Background

In the traditional industrial digitization process, the acquisition of industrial data is an important link. In a factory where network wiring is inconvenient, data generated by production equipment may be transmitted over a wireless network. For example, a System on Chip (SoC) module is usually used to collect data, and then the data is transmitted to a data receiver such as a cloud platform by using a wireless communication technology such as 4G or 5G.

In the prior art, the power supply for the data acquisition module (typically a 12V or 24V dc regulated power supply) is typically provided by the production equipment of the factory. However, due to considerations such as electricity cost and production safety, a plant may be powered off when production equipment is shut down or not needed for a while. This will result in the data acquisition module also being powered down and unable to transmit status data to the recipient.

Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

In the existing industrial data collection field based on wireless transmission, a data collection (SoC) module collects status data of production equipment and then transmits the status data through a wireless transmission module, for example, the data collection module sends the data to a 4G/5G module, and then the data is sent to a data receiver (such as a cloud platform) through an antenna device by the 4G/5G module. However, existing data collection modules are typically powered by the production equipment of the plant, and are unable to transmit status data when the production equipment is shut down or temporarily powered off.

In order to solve the above problems, it has been proposed to separately configure an independent Power Supply, such as an Uninterruptible Power Supply (UPS) or a large-capacity battery, for the data acquisition module, so as to Supply Power to the data acquisition module when the production equipment is powered off, thereby ensuring data transmission. However, since the data acquisition and transmission module consumes a lot of power and requires a large amount of energy, on one hand, such a solution is very costly, and on the other hand, a large-capacity independent power supply is bulky and heavy, and therefore is not suitable for large-area popularization.

Therefore, the application provides an improved data acquisition system for solving the problem that the data acquisition module in the prior art cannot transmit state data after being powered off, and the improved data acquisition system can be applied to data acquisition gateway equipment. Fig. 1 is a schematic view of an application scenario of a data acquisition system according to an embodiment of the present application. As shown in fig. 1, the data acquisition system can be applied to industrial data acquisition of production equipment of a conventional manufacturing industry. In the data acquisition system, the data acquisition module CAN acquire the state data of the industrial equipment through various ways, for example, acquiring digital signals, analog signals, Programmable Logic Controller (PLC) signals, serial communication interface standard (RS232, RS485, RS422, CAN) signals, industrial ethernet signals and the like of the industrial equipment. In particular, the SoC may be employed to implement the functionality of the data acquisition module.

When the industrial equipment is normally powered on to work, the system is powered by an external power supply, and for example, the power can be supplied by machine tool type production equipment. The data acquisition module transmits the acquired data to a data receiver through the wireless transmission module. Meanwhile, the data acquisition module can synchronize the acquired state data to the control module for storage, so that after the production equipment is abnormal or the data acquisition module is powered off, the control module can send unsent data to a data receiver through the wireless transmission module. Specifically, a Micro Controller Unit (MCU) may be used to implement the function of the control module. The MCU has a much lower power consumption than the SoC, and therefore, an internal power supply module with a lower capacity (e.g., a low-capacity, low-cost lithium battery) may be provided in the system.

When no external power supply supplies power, the power supply switching module is switched to be supplied with power by the internal power supply module. At the moment, the control module replaces the data acquisition module to transmit abnormal state data through the wireless transmission module. Specifically, the link switching module switches the data link between the data acquisition module and the wireless transmission module into the data link between the control module and the wireless transmission module. At this time, the wireless transmission module is also switched to the operation mode with lower power consumption. Therefore, the problem that the data acquisition module cannot transmit state data after power failure is solved, power consumption can be saved, and cost is saved.

The above embodiments are illustrations of technical principles and exemplary application frameworks of the embodiments of the present application, and specific technical solutions of the embodiments of the present application are further described in detail below through a plurality of embodiments.

Example one

Fig. 2a is a system block diagram of a data acquisition system according to an embodiment of the present application. As shown in fig. 2a, the data acquisition system provided by the present application includes: the device comprises a data acquisition module 1, a wireless transmission module 2 and a control module 3. The data acquisition module 1 is provided with a first power consumption control module 3 with second power consumption, and the second power consumption is lower than the first power consumption.

The data acquisition module 1 is used for acquiring first state data for identifying the state of the industrial equipment and transmitting the first state data through the wireless transmission module 2; the control module 3 is configured to transmit a part of the first state data, that is, the first state data that is acquired by the data acquisition module 1 and is not transmitted, through the wireless transmission module 2 according to the state of the data acquisition module 1. In the embodiment of the present application, the data acquisition module 1 may be a module for acquiring data of an industrial device, such as an industrial intelligent gateway, and the wireless transmission module 2 may be a module having a network connection and transmission function, which may transmit data to the outside by means of a WiFi, 3G, 4G, 5G, or other network.

In the embodiment of the present application, when the external power supply supplies power normally, the data acquisition module 1 acquires the state of the production equipment, that is, the first state data, and then transmits the data to the data receiver through the wireless transmission module 2. The control module 3 acquires the state data of the data acquisition module 1 and transmits part of the first state data through the wireless transmission module 2 according to the state of the data acquisition module 1. For example, when the control module 3 determines that the data acquisition module 1 is in the power-off state, the first state data that is not transmitted by the data acquisition module 1 is transmitted through the wireless transmission module 2. In the embodiment of the present application, the control module 3 may be a module having a control function, such as an MCU.

The data acquisition system provided by the embodiment of the application can further include: an internal power supply module 4. The internal power supply module 4 may be used to supply power to the control module 3. For example, in the present embodiment, the internal power supply module 4 may be a lithium battery or a battery of other materials. Specifically, a power switching module 5 may be provided for monitoring the external power source and the internal power supply module 4, and controlling the internal power supply module 4 to supply power when the external power source stops supplying power. When power is supplied to the internal power supply module 4, the power switching module 5 can also generate a control signal to control the power lamp of the internal power supply module 4 to flash, so as to send a prompt to related workers, the internal power supply module 4 is started, and the workers are reminded to access an external power supply as soon as possible, so as to prevent the electric quantity of the internal power supply module 4 from being exhausted. When the power switching module 5 detects that the external power supplies power, the external power can also be controlled to charge the internal power supply module 4. In the embodiment of the present application, the power switching module 5 may be a PMIC (power management IC) or a PMU (power management unit).

In the embodiment of the present application, a first switch unit 6, a second switch unit 7, and a third switch unit 8 may be respectively disposed between the power switching module 5 and the data acquisition module 1, the control module 3, and the wireless transmission module 2. When the external power supply supplies power, the power supply switching module 5 controls the first switching unit 6, the second switching unit 7 and the third switching unit 8 to be switched on; when the internal power supply module 4 supplies power, the power supply switching module 5 controls the first switching unit 6 to be turned off, and controls the second switching unit 7 and the third switching unit 8 to be turned on. Therefore, the data acquisition module 1, the control module 3 and the wireless transmission module 2 are independently powered, and the power consumption of each module is minimum under different power supply states. Specifically, a Power Management (Power Management IC/Power Management Unit; PMIC/PMU for short) circuit may be adopted to implement the function of the Power switching module 5.

In the embodiment of the present application, the control module 3 may be used to control different operation modes of the wireless transmission module 2. Specifically, when the external power supply supplies power, the control module 3 controls the wireless transmission module 2 to start the first operation mode; when the internal power supply module 4 supplies power, the control module 3 controls the wireless transmission module 2 to start the second operation mode, wherein the power consumption of the wireless transmission module 2 in the first operation mode is lower than the power consumption in the second operation mode. Specifically, the wireless transmission module 2 communicates with the data acquisition module 1 through a first data link (e.g., USB2.0, USB3.0, PCIe, etc.) having a first transmission rate and a second data link (e.g., UART, etc.) having a second transmission rate in the first operation mode; in a second operating mode, the wireless transmission module 2 communicates with the control module 3 via a second data link, wherein the first transmission rate is higher than the second transmission rate. In the embodiment of the present application, the data amount of the abnormal state information is small, and therefore, the control module 3 may send data to the data receiving side at a low transmission rate (for example, send data in the form of heartbeat packets, etc.) at regular time.

In the data acquisition system provided in the embodiment of the present application, a link switching module 9 (e.g., a data selector circuit) may be provided to switch the data link between the data acquisition module 1/the control module 3 and the wireless transmission module 2. Specifically, when the external power supply supplies power, the link switching module 9 may control the wireless transmission module 2 to communicate with the data acquisition module 1 through the second data link; when the internal power supply module 4 supplies power, the link switching module 9 controls the wireless transmission module 2 to communicate with the control module 3 through the second data link. Of course, when the internal power supply module 4 supplies power, the first data link between the data acquisition module 1 and the wireless transmission module 2 is also automatically interrupted, so that the operation power consumption of the wireless transmission module 2 is reduced.

Fig. 2e shows a schematic diagram of data link switching according to an embodiment of the present application. As shown in fig. 2e, the source of the data transmitted by the wireless transmission module 2 can be switched by the control signal of the link switching module 9. For example, the data 1-n from the data acquisition module and the data 1-n from the control module can be switched by the control signal, so that whether the wireless transmission module 2 transmits the data from the data acquisition module 1 or the data from the control module 3 can be controlled. For example, the wireless transmission module 2 may be controlled to communicate with the data acquisition module 1, i.e., the SoC, through the second data link when the value of the control signal is zero, and the wireless transmission module 2 may be controlled to communicate with the control module 3 through the second data link when the value of the control signal is one.

For example, in the embodiment of the present application, when the industrial device to which the data acquisition system is connected is powered on, the power supply state to the data acquisition system may be detected by the power switching module 5, such as a power management unit (PMIC/PMU) circuit. When it is determined that the power supply of the data acquisition system has been enabled, for example, the industrial device has been turned on and thus provides power to the data acquisition system through its internal power supply circuitry, or an external power supply that provides power to the industrial device has been enabled and thus the external power supply has begun to provide power to the data acquisition system. Therefore, when the power supply switching module 5 has confirmed that the external power supply of the data acquisition system has been enabled, the power supply switching module 5 supplies power to the control module 3 using the external power supply as described above, for example, may cause the control module 3 to complete the startup operation. Then, the control module 3 may control the power switching module 5 to supply power to the data acquisition module 1 and the wireless transmission module 2.

In the case where the power supply of the external power source is obtained, the data acquisition module 1 and the wireless transmission module 2 start a startup operation, such as loading various drivers, and optionally cause various peripherals connected thereto to perform the startup operation. After the wireless transmission module 2 completes the start operation, an external data connection may be established with the internet, so that an external server, such as a cloud server, may be connected to facilitate the transmission of data collected by the data collection system to the outside.

In the case of using the external power source for power supply, i.e. in the normal operation state of the data acquisition system, as described above, the data acquisition module 1 acquires data of the industrial equipment and transmits the data through the first data link and the second data link between the data acquisition module and the wireless transmission module 2.

FIG. 2b shows a flow diagram of data acquisition system and industrial equipment start-up according to the present application. As shown in fig. 2b, in step S2011, the industrial device and the data acquisition system to be subjected to the state acquisition are turned on. For example, the industrial equipment and the data acquisition system connected to the industrial equipment may be activated by pressing a switch or remotely sending a power-on signal. In step S2012, it may be detected whether power is supplied from the external power source. When it is detected that the external power source supplies power, in step S2013, the control module 3 may be powered by the external power source to start the control module 3. Next, in step S2014, the data acquisition module 1 and the wireless transmission module 2 may be powered by an external power source, and the control status data is transmitted via the data link between the data acquisition module 1 and the wireless transmission module 2. In this step, the start of the control module 3 may be completed, and the driver of the wireless transmission module 2 and other related drivers are loaded accordingly, and the establishment of the wireless transmission link between the wireless transmission module 2 and an external server, for example, a cloud server, is completed. In step S2015, the operating state information of the industrial device may be collected as first state data by the data collection module 1, and the collected first state data is transmitted to the external server through the wireless transmission module 2. When the external power supply is not detected, in step S2016, power may be supplied to the control module 2 through the internal power supply module, thereby completing the start-up of the control module 2. In step S2017, the control module 2 may confirm that no external power is supplied, and store state information identifying abnormal power-on in the internal memory. In step S2018, a control signal may be further generated to prompt the worker. For example, the power lamp of the external power module may be controlled to flash to alert the operator of such an abnormal condition.

In addition, in the embodiment of the present application, there are a plurality of abnormal states, and the control module 3 may perform different operations for different abnormal states.

Specifically, for the case of the abnormal state one, i.e. the power failure of the data acquisition module 1:

the control module 3 synchronously stores the first state data acquired by the data acquisition module 1, and transmits the second state data and the newly stored first state data through the wireless control module 2 when acquiring the second state data identifying the power-off state of the data acquisition module 1.

For example, in the case of normal power supply, the data acquisition module 1 may transmit the first status data of the industrial device to the control module 3 while transmitting the first status data to the outside through the wireless transmission module, and when acquiring the first status data of the industrial device again, may similarly transmit the first status data acquired again to the control module 3 while transmitting the first status data to the outside through the wireless transmission module, so as to update the current status data of the industrial status stored in the control module 3. Therefore, when the power supply of the data acquisition module 1 is interrupted, for example, when the control module 3 acquires the second state data identifying the power-off state of the data acquisition module 1, the control module 3 may know, according to the second state data, that the data acquisition module 1 cannot continuously transmit the first state data of the industrial device to the outside, and since the data acquisition module 1 may synchronously update the currently acquired state data to the control module 3 in each acquisition turn of the state data of the industrial device, the control module 3 may transmit the state data of the industrial device, which is last synchronized to the control module 3 before the power supply of the data acquisition module 1 is interrupted, when the power supply of the data acquisition module 1 is interrupted and the first state data of the industrial device cannot be transmitted to the outside.

In addition, aiming at the abnormal state II, namely the abnormal starting condition of the equipment:

when the internal power supply module 4 supplies power, when the control module 3 recognizes that the first state data contains third state data identifying an abnormal starting state of the acquisition system, the control module 3 acquires and stores the third state data, and synchronizes the third state data to the data acquisition module 1 after the industrial equipment is normally started, so that the data acquisition module 1 transmits the third state data through the wireless transmission module 2 to report the abnormal starting state before the data receiver is prepared.

For example, if the data acquisition system is started without external power, for example, if the start button is pressed or the data acquisition system is woken up by the internet, the power switching module 5 may detect the external power, and therefore detect that the data acquisition system is started but the external power is not supplied in this case, and therefore, in this embodiment, it may be determined as an abnormal power-on condition. In this case, the power switching module may supply power to the control module 3 through an internal power supply module such as a lithium battery, so that the control module 3 completes the start-up under the power supply of the internal power supply module. Then, since the abnormal power-on condition is detected, the control module 3 may read the third status data identifying the abnormal power-on condition as described above, store the third status data in an internal memory, for example, a register or an internal flash memory (flash), and may further send a control signal, for example, control an external power supply or flash indicator on the data acquisition device to indicate the abnormal status to the staff.

In addition, for abnormal state three-the case of external power outage:

the control module 3 can also read a first register used for recording the electric quantity of the external power supply in the power supply switching module 5, and when a power-off signal is acquired from the first register, the control module 3 sends a power-off notification instruction to the data acquisition module 1 so that the data acquisition module 1 disconnects a data link with the wireless transmission module 2; meanwhile, the control module 3 controls the power supply switching module 5 to stop supplying power to the data acquisition module 1.

Fig. 2c shows a schematic flow chart of the data acquisition system according to the embodiment of the present application in the case of power failure of the external power supply module. For example, in the embodiment of the present application, in a normal power supply state of the external power supply, both the data acquisition system and the external device are in a normal operation state. In this normal operation state, as shown in fig. 2c, in step S2021, the control module 3 may periodically acquire the record information of the power supply state to the external power supply in the power supply switching module 5. For example, the power supply switching module 5 may record power supply state information of the external power supply in a register inside thereof, and the control module 3 may periodically access the register to acquire the power supply state. When the control module 3 confirms the external power supply and is turned off based on the acquired power supply state information in step S2021, power-off notification information may be transmitted to the data collection module 1 in step S2022 so that it is ready for power-off. Accordingly, in step S2023, the data collection module 1 may stop data communication with the wireless transmission module 2 upon receiving the power-off notification transmitted by the control module 3, and transmit a notification signal to the control module 3 upon confirming that the data communication has been stopped. Therefore, in step S2024, in the case where the data acquisition module 1 has stopped data transmission with the wireless transmission module 2, the data acquisition system may switch to the mode in which the internal power supply module 4 supplies power. For example, the wireless transmission module 2 can be controlled by the control module 3 to enter a low power consumption mode, and accordingly a low rate transmission link that consumes less power is used to establish a data connection with the control module 3, and finally the control module 3 can control the power switching module 5 to switch the power supply of the data acquisition module to the internal power module 4. In this case, in step S2025, the data acquisition module 2 may enter a shutdown state in response to the power-off notification of the control module 3, and also switch the data link of the wireless transmission module 2 to the data transmission link with the control module 3 to reduce power consumption.

In the case that the internal power supply module 4 supplies power to the data acquisition system, particularly to the control module 3 and the wireless transmission module 2 in the low power operation state, in step S2026, the control module 3 may further periodically send status information, for example, a heartbeat packet, to the outside, for example, a cloud server, through the wireless transmission module 2, where the current status information of the data acquisition system, particularly the power information of the internal power supply module 4, may be included in the status information. Therefore, the outside can know the online state of the data acquisition equipment through the state information.

In addition, aiming at the abnormal state four-the abnormal condition of the data acquisition module 1:

fig. 2d is a schematic flow chart illustrating a failure of a data acquisition module in the data acquisition system according to the embodiment of the present application. As shown in fig. 2d, the data collection module 1 may communicate with the control module 3 at step S2031. For example, the data collection module 1 may synchronously update the currently acquired first state data of the industrial equipment to the control module 3. In step S2032, the control module 3 checks the status data of the data collection module 1 to determine whether the data collection module 1 is operating normally. After the abnormal state of the data acquisition module 1 is detected, the training query operation can be performed for multiple times to eliminate the problem of false alarm caused by data interference in the communication process. Specifically, after the control module 3 receives the fourth state data identifying the abnormal state of the data acquisition module 1, and when it is determined that the number of continuous receiving times of the fourth state data is greater than the preset threshold, in step S2033, the control module 3 controls the link switching module 9 to disconnect the second data link between the data acquisition module 1 and the wireless transmission module 2, open the second data link between the control module 3 and the wireless transmission module 2, and at the same time, the control module 3 controls the power switching module 5 to stop supplying power to the data acquisition module 1. In step S2034, the control module 3 may send out the last time before the interruption, i.e., the newly stored first state data, through the data link with the wireless transmission module 2, with power supplied by the internal power supply module. And the abnormal condition can be simultaneously sent to the outside, thereby achieving the effect of alarming the abnormal working of the equipment.

For example, in the embodiment of the present application, in a normal power supply state of the external power supply, both the data acquisition system and the external device are in a normal operation state. In this normal operating state, the control module 3 may periodically communicate with the data acquisition module 1, as described above. For example, the data acquisition module 1 may periodically transmit status information of the data acquisition module 1 to the control module 3 through a communication bus between the control module 3 and the data acquisition module 1. Therefore, the control module 3 may confirm the operation state of the data collection module 1 based on the received state information of the data collection module 1. For example, if the state information of the data acquisition module 1 indicates that the state is abnormal or the control module 3 does not receive the state information of the data acquisition module 1 continuously for several periods, the control module 3 may confirm that the data acquisition module 1 is in an abnormal state, in which case the data acquisition system may refer to the above-mentioned shutdown procedure, close the data transmission of the data acquisition module 1, change the operation mode of the wireless transmission module 2 to low-power operation and establish a low-rate data transmission channel between the wireless transmission module 2 and the control module 3, and so on.

In addition, according to the embodiment of the present application, the data acquisition system may include a switch assembly for switching the operation mode of the control module 3. As described above, the control module 3 may switch to the low power mode to communicate with the wireless transmission module 2 by using the low power data transmission channel in case of power failure or abnormality of the data acquisition module 1. However, in some cases, a switch assembly may be additionally provided to further advance or actively switch the operation mode of the control module 3 according to an external condition or an operation condition of the industrial equipment monitored by the data acquisition system. For example, the switch component may detect and analyze the working state information of the industrial device collected by the data collection module 1 to make the working state of the industrial device unstable, so as to determine that the low power operation mode of the control module 3 is started in advance when a problem may occur, so as to operate the low power mode of the control module 3 while the data collection module 1 is still working normally, thereby avoiding a failure of the last data transmission between the data collection module 1 and the control module 3 due to the burst state of the industrial device by the data collection module 1. In the embodiment of the present application, the switch assembly may also have a manual mode, so that an operator may manually turn on the low power mode of the control module 3 according to actual needs to simultaneously operate the normal collection mode of the data collection module 1 and the low power mode for performing backup.

In addition, in the embodiment of the present application, it can also be determined whether and when to enable the low power mode, i.e. the backup mode, of the control module 3 according to the working scenario or working requirement of the data acquisition module 1, for example, the type or occasion of the industrial equipment to be acquired by the data acquisition module 1. For example, the low power mode of the control module 3 may be automatically enabled according to the detection result of various sensors provided in the field according to the detection result of the sensors. For example, when the sensors detect that the supply voltage of the industrial device is not stable, or when a lightning or excessively humid environment is detected, the low-power mode of the control module 3 may be automatically enabled to synchronously backup the status data of the industrial device collected by the data collection module 1. In addition, the backup mode of the control module 3 may also be enabled according to the current task content of the industrial device, for example, when the currently performed task of the industrial device, which is the object of data collection, is a very important task, or when the currently performed task needs to be backed up more frequently, according to the requirement of the task or at a predetermined frequency, i.e., a period.

In addition, since the data acquisition module is often disposed in an environment such as a workshop of a factory, which is easily affected by various environments, such as various noises, foreign matters such as dust, or even electromagnetic interference from various external devices, the control module 3 may be configured to further perform multiple communications, such as polling query, on the data acquisition module 1 when detecting that the data acquisition module 1 is in an abnormal state, so as to accurately confirm the operating state of the data acquisition module 1 and remove the interference of the external environment.

After the abnormal state of the data acquisition module 1 is finally confirmed, in addition to executing the shutdown operation, the control module 3 may further store abnormal information indicating the abnormal state of the data acquisition module 1 inside the control module 3, such as an internal register or an internal Flash memory (Flash), so that after the wireless transmission module 2 and the control module 3 establish a low-rate data transmission channel, the abnormal information may be transmitted to the outside through the wireless transmission module to send an alarm signal.

Further, in this embodiment of the application, the control module 3 may poll the power switching module 5 through the I2C bus to read the power of the internal power module 4, and transmit power information data to the data receiving side to notify the system that there is a risk of a disconnection. Specifically, the control module 3 may read the power information data from the second register in the power switching module 5 for recording the power of the internal power supply module 4 at regular time, and transmit the power information data through the wireless transmission module 2.

The data acquisition system that this application embodiment provided, the data acquisition module transmits the state data of the industrial equipment who gathers through wireless transmission module under the condition of normal power supply to the control module that will gather the data acquisition module and the industrial equipment's that does not transmit state data through wireless transmission module transmission to the data receiver through extra setting when the data acquisition module is in abnormal state, thereby solve the problem that can't transmit state data after the data acquisition module outage among the prior art.

Example two

Fig. 3 is a flowchart of an embodiment of a data acquisition method provided by the present application, where the method may be applied to a data acquisition system including a data acquisition module and a wireless transmission module, and an execution subject may be a device having a data acquisition function, such as an intelligent digital industrial device, or may be an apparatus or chip integrated on the device, such as an industrial acquisition gateway, or the like. As shown in fig. 3, the data acquisition method includes the following steps:

s301, first state data of the industrial equipment collected by the data collection module is received.

In this application embodiment, when the external power source normally supplies power, the state of the production equipment, that is, the first state data, can be acquired by the data acquisition module, and then the data is transmitted to the data receiver through the wireless transmission module.

S302, second state data of the data acquisition module are obtained.

In the process of acquiring the first state data and sending the first state data to the outside by the data acquisition module, the data acquisition method of the embodiment of the application can acquire the state data of the data acquisition module 1, namely, the second state data for identifying the state of the data acquisition module. In this embodiment of the application, the data acquisition module may be in a state powered by an external power source, and in this state, the data acquisition module and the wireless transmission module are in a normal operation state, that is, both are powered by the external power source, and the data acquisition module acquires the state data of the industrial equipment and then transmits the state data to the outside through a data transmission channel between the data acquisition module and the wireless transmission module. In such a state, the data collection module may also be in an abnormal state for various reasons, such as a power outage or a fault.

And S303, according to the second state data, when the data acquisition module is in an abnormal state, transmitting the first state data which is acquired by the data acquisition module and is not transmitted through the wireless transmission module.

In the embodiment of the application, when the data acquisition module is in a normal operation state, the data acquisition module transmits the acquired state data of the industrial equipment to the outside through the wireless transmission module. However, in an abnormal state, for example, in a power-off state, since the data collection module loses power supply, collected state data cannot be transmitted to the outside. This also poses a problem in the prior art in that an external device such as a cloud server cannot know the exact state of the data acquisition system. Therefore, in the embodiment of the application, when the state of the data acquisition module is in a power-off or abnormal state, at least a part of the acquired state data can be transmitted to the outside, such as a cloud server, through the wireless transmission module, so that the outside can know the state of the data acquisition system through at least a part of the state data sent out in this way.

Therefore, according to the data acquisition method provided by the embodiment of the application, the data acquisition module transmits the acquired state data of the industrial equipment through the wireless transmission module under the condition of normal power supply, and the additionally arranged control module transmits the state data of the industrial equipment which is acquired by the data acquisition module and is not transmitted to the data receiver through the wireless transmission module when the data acquisition module is in an abnormal state, so that the problem that the data acquisition module cannot transmit the state data after power failure in the prior art is solved.

EXAMPLE III

Fig. 4 is a flowchart of another embodiment of a data acquisition method provided by the present application. As shown in fig. 4, on the basis of the embodiment shown in fig. 3, the data acquisition method provided by this embodiment may include the following steps:

s401, first state data of the industrial equipment collected by the data collection module is received.

In the embodiment of the application, the data acquisition system may have an external power source and an internal power supply module, and therefore, when the external power source supplies power normally, the data acquisition module may acquire the state of the production equipment, that is, the first state data, and then transmit the data to the data receiving party through the wireless transmission module.

S402, monitoring the states of the power supplies of the data acquisition module and the wireless transmission module.

And S403, when the external power supply is started, the external power supply is used for supplying power to the data acquisition module and the wireless transmission module.

In the embodiment of the application, the data acquisition system and the external equipment are in a normal operation state under the normal power supply state of the external power supply. In this normal operation state, the state of the power supply may be monitored, and for example, the record information of the power supply state of the external power supply may be periodically acquired. For example, the record information of the power supply state may be periodically acquired. When it is confirmed that the external power supply has been enabled based on the acquired record information of the power supply state, the power supply may be switched to the external power supply to supply power to the data acquisition system, for example, the data acquisition module and the wireless transmission module. In this case, the method may further include:

and S407, controlling the wireless transmission module to transmit the first data through the first data link and transmit the second data through the second data link.

For example, the wireless transmission module may be further controlled to transmit first data over a first data link having a first transmission rate and to transmit second data over a second data link having a second transmission rate when powered by an external power source. In an embodiment of the application, the first transmission rate is higher than the second transmission rate. Therefore, in the embodiment of the present application, the wireless transmission module can be operated in the operation modes with different powers through the data links with the two different transmission rates. For example, the wireless transmission module may communicate with the data collection module via a first data link (e.g., USB2.0, USB3.0, PCIe, etc.) having a first transmission rate and a second data link (e.g., UART, etc.) having a second transmission rate in a first mode of operation, and transmit a portion of the first status data and/or the exception information via the second data link in a second mode of operation.

And S404, when the external power supply is stopped, stopping supplying power to the data acquisition module, and switching the power supply of the wireless transmission module into the internal power supply module.

In the embodiment of the present application, when it is confirmed that the external power supply has been disconnected or deactivated, the power supply may be switched to the internal power supply module for supplying power. By continuing to supply power through the internal power supply module, part of the first state data can be continuously transmitted through the wireless transmission module. In this state, it may further include:

s408, controlling the wireless transmission module to transmit second state data for identifying the power-off state of the data acquisition module and the newly stored first state data through a second data link.

In the power-off state, the data communication between the data acquisition module and the wireless transmission module can be stopped, and when the data communication is confirmed to be stopped, the power supply mode of the internal power supply module is switched. For example, the wireless transmission module may be controlled to enter a low power consumption mode and a data connection is established using a correspondingly less power consuming low rate transmission link.

Further, in the power-off state, the following processing may be further included:

s405, a control signal is generated.

And S406, sending the control signal to an internal power supply module.

In the embodiment of the application, when the power supply is switched to the internal power supply module under the condition that the external power supply is determined to be disabled, a control signal can be further generated, and the control signal can control a power lamp of the internal power supply module to be in a flashing state, so that the internal power supply module can enable the power lamp to flash according to the control signal, and a worker can be reminded conveniently.

In addition, in the power-off state, third state data identifying an abnormal power-on state of the data acquisition system can be acquired. When the internal power supply module supplies power, when the first state data is identified to contain third state data for identifying the abnormal starting state of the data acquisition system, the third state data can be acquired and stored, and after the data acquisition system is normally started, the third state data is synchronized to the data acquisition module, so that the data acquisition module transmits the third state data through the wireless transmission module to report the abnormal starting state before the data acquisition module is ready to a data receiver.

For example, if the data acquisition system is started without external power, for example, if a start button is pressed or the data acquisition system is woken up by the internet, status data identifying abnormal startup of the system may be acquired and thus, in this case, it may be detected that the data acquisition system is started but no external power is supplied, and thus, in this embodiment of the present application, it may be determined as an abnormal startup situation. In this case, power may be supplied through an internal power supply module such as a lithium battery, so that the data acquisition system completes low-power startup under the power supply of the internal power supply module and stores the abnormal startup information.

Therefore, when the external power supply is started, the data acquisition module can be controlled to transmit the third state data through the wireless transmission module.

S409, second state data for identifying the state of the data acquisition module is obtained.

In the process that the data acquisition module acquires the first state data and sends the first state data to the outside, the data acquisition method of the embodiment of the application can acquire the state data of the data acquisition module, namely the second state data for identifying the state of the data acquisition module. In this embodiment of the application, the data acquisition module may be in a state powered by an external power source, and in this state, the data acquisition module and the wireless transmission module are in a normal operation state, that is, both are powered by the external power source, and the data acquisition module acquires the state data of the industrial equipment and then transmits the state data to the outside through a data transmission channel between the data acquisition module and the wireless transmission module.

And S410, sending part of the first state data through the wireless transmission module according to the second state data.

Further, in this embodiment, the data acquisition method of this application may further include:

and S411, acquiring the electric quantity information data of the internal power supply module.

And S412, transmitting the electric quantity information data to the outside through the wireless transmission module.

Therefore, in the embodiment of the application, the electric quantity information data of the electric quantity of the internal power supply module can be acquired, the electric quantity information data is transmitted to the data receiving party, and the system is informed of the risk of disconnection.

In the embodiment of the application, when the data acquisition module is in a normal operation state, the data acquisition module transmits the acquired state data of the industrial equipment to the outside through the wireless transmission module. However, in an abnormal state, for example, in a power-off state, since the data collection module loses power supply, collected state data cannot be transmitted to the outside. This also poses a problem in the prior art in that an external device such as a cloud server cannot know the exact state of the data acquisition system.

Therefore, in the embodiment of the application, when the state of the data acquisition module is in a power-off or abnormal state, at least a part of the acquired state data can be transmitted to the outside, such as a cloud server, through the wireless transmission module, so that the outside can know the state of the data acquisition system through at least a part of the state data sent out in this way.

As shown in fig. 5, the data acquisition device provided in the embodiment of the present application includes: a receiving unit 51, an obtaining unit 52 and a processing unit 53.

The obtaining unit 52 may be configured to obtain second status data of the data acquisition module.

In the process of acquiring the first state data and sending the first state data to the outside by the data acquisition module, the data acquisition apparatus according to the embodiment of the present application may acquire the state data of the data acquisition module 1, that is, the second state data identifying the state of the data acquisition module, by using the acquisition unit 52. In this embodiment of the application, the data acquisition module may be in a state powered by an external power source, and in this state, the data acquisition module and the wireless transmission module are in a normal operation state, that is, both are powered by the external power source, and the data acquisition module acquires the state data of the industrial equipment and then transmits the state data to the outside through a data transmission channel between the data acquisition module and the wireless transmission module. In such a state, the data collection module may also be in an abnormal state for various reasons, such as a power outage or a fault.

The processing unit 53 may be configured to transmit the first state data, which is acquired by the data acquisition module and is not transmitted, through the wireless transmission module when the data acquisition module is in the abnormal state according to the second state data.

In the embodiment of the application, when the data acquisition module is in a normal operation state, the data acquisition module transmits the acquired state data of the industrial equipment to the outside through the wireless transmission module. However, in an abnormal state, for example, in a power-off state, since the data collection module loses power supply, collected state data cannot be transmitted to the outside. This also poses a problem in the prior art in that an external device such as a cloud server cannot know the exact state of the data acquisition system. Therefore, in the embodiment of the present application, when the data acquisition module is determined to be in the power-off or abnormal state according to the state of the data acquisition module acquired by the acquisition unit 52, the processing module 53 may transmit the first state data, which is not transmitted by the data acquisition module and received by the receiving module 51, to the outside, such as a cloud server, through the wireless transmission module, so that the outside can know the state of the data acquisition system through at least a part of the state data thus transmitted.

Therefore, according to the data acquisition device provided by the embodiment of the application, the data acquisition module transmits the acquired state data of the industrial equipment through the wireless transmission module under the condition of normal power supply, and transmits the state data of the industrial equipment which is acquired by the data acquisition module and is not transmitted to the data receiver through the wireless transmission module when the data acquisition module is in an abnormal state, so that the problem that the state data cannot be transmitted after the data acquisition module is powered off in the prior art is solved.
