Fig. 1 is a schematic structural diagram of a remote upgrade system according to an embodiment of the present application, and the system is specifically a remote upgrade system applied to a lightning protection internet of things. The system comprises the background server and the lightning protection monitoring unit, and can realize remote upgrade of the lightning protection monitoring unit. The lightning protection monitoring Unit comprises a micro control Unit (MCU for short). In this embodiment, referring to fig. 1, the background server is an upper computer 10, and the micro control unit is a lower computer 20.

The upper computer 10 runs an Application (APP). The application program is used for receiving the signals fed back by the lightning protection monitoring unit, analyzing and processing the signals and storing the data in the background server. The current data and the historical data can be viewed on the application program, and an instruction can be sent to the lightning protection monitoring unit.

Fig. 2 is a schematic structural diagram of a lower computer according to an embodiment of the present disclosure, and referring to fig. 2, the lower computer 20 includes a memory 21, and the memory 21 is a flash memory (flash). In the present embodiment, the memory 21 includes an outbound area 211, a backup area 212, and an upgrade area 213.

In this embodiment, to realize the remote upgrade of the lightning protection monitoring unit, the lower computer 20 includes two sets of programs: the first set of programs is used as original programs for leaving a factory (hereinafter referred to as factory programs); the second set of programs is an IAP (Application Programming) program, which is a program requiring an upgrade (which may be referred to as an online upgrade program, hereinafter referred to as an upgrade program), specifically, upgrade program firmware.

The embodiment also provides a remote upgrading method, which can be applied to the remote upgrading system. Fig. 3 shows an information interaction diagram of the foregoing remote upgrade system, where steps a1 to a5 are specifically applied to the lower computer 20, and steps C1 to C4 are specifically applied to the upper computer 10, where step C1 and step C2 are optional.

And step C1, receiving an upgrade instruction sent by the user, wherein the upgrade instruction corresponds to the lower computer 20.

The application program running on the upper computer 10 provides a column of interface specially used for remote upgrading, and new upgrading program firmware can be added for selective upgrading; in addition, the aforementioned interface also has an upgraded diary, such as: the upgrade object, the upgrade time, state, version, etc.

Determining a lightning protection monitoring unit to be upgraded, for example, determining an ID (Identification) of the lightning protection monitoring unit, where the ID of the lightning protection monitoring unit to be upgraded may be specifically selected by a user; the application program has a corresponding upgrading program, such as adding a new upgrading program firmware by a user; then, an upgrade instruction issued by the user is received, for example, the user clicks the upgrade to issue an upgrade instruction to the application program, where the upgrade instruction is used to upgrade the selected lightning protection monitoring unit (the lower computer 20).

And step C2, receiving the heartbeat packet sent by the lower computer 20 in response to receiving the upgrade instruction.

After the step C1 is completed, the upper computer 10 has received the upgrade instruction, and the application program is ready, and then the upper computer 10 receives the heartbeat packet that is periodically uploaded by the object unit (i.e., the lightning protection monitoring unit) corresponding to the upgrade instruction, where the received heartbeat packet indicates that the lower computer 20 of the lightning protection monitoring unit is operating normally.

And step C3, sending the upgrading communication data, wherein the upgrading communication data comprises an upgrading program.

After receiving the heartbeat packet of the lower computer 20, the application program sends an upgrade packet (including an upgrade program) plus the protocol header and the protocol trailer as upgrade communication data to the lower computer 20. Accordingly, the lower computer 20 executes step a 1.

Step A1, receiving upgrade communication data, wherein the upgrade communication data comprises an upgrade program.

As described above, the upper computer 10 transmits the upgrade communication data to the lower computer 20 through the application program, and accordingly, the lower computer 20 receives the upgrade communication data.

Fig. 4 is a schematic flowchart of step a1 of the remote upgrade method provided in this embodiment, where in this embodiment, step a1 specifically includes step a11 and step a 12.

And step A11, receiving the protocol header of the upgrade communication data and the upgrade program, and caching the upgrade program.

As described above, the upgrade communication data sent by the upper computer 10 to the lower computer 20(MCU) includes the protocol header, the upgrade program, and the protocol trailer. In the normal operation process, when the protocol header corresponding to the upgrade program is received from the upper computer 10, the lower computer 20 stores the corresponding code in the cache of the RAM (Random Access Memory) until the protocol end at the end, thereby implementing the cache of the upgrade program.

And step A12, if the protocol end of the upgrading communication data is received within the set time, the upgrading program is verified to obtain a verification result.

It takes time for the upper computer 10 to transmit the upgrade communication data, and if a missing code or an error occurs during the transmission, the lower computer 20 cannot receive the complete upgrade communication data. For this reason, in the present embodiment, the lower computer 20 sets the time of receiving the protocol end of the upgrade communication data, and if the protocol end of the upgrade communication data is received within the set time, indicates that the communication is successful. After receiving the protocol trailer of the upgrade communication data, the lower computer 20 checks the upgrade program therein. Specifically, the aforementioned step a12 includes a step a121 and a step a 122. Fig. 5 is a flowchart illustrating step a12 of the remote upgrade method provided in this embodiment.

And step A121, generating a real-time check code of the upgrading program.

After receiving the complete upgrade communication data, the lower computer 20 checks the upgrade program therein, specifically, performs CRC32 (cyclic redundancy check 32) check, and generates a corresponding real-time check code.

And A122, comparing the real-time check code with a preset check code to obtain a check result.

And after the real-time check code of the upgrading program is generated, comparing the real-time check code with a preset check code. The preset check code is contained in the upgrading communication data, and the preset check code and the upgrading program are jointly used as an upgrading packet; illustratively, the preset check code is the last 4 bytes of the upgrade package, wherein the upgrade communication data has a 4-byte CRC32 check code as a suffix bin format file, and thus the real-time check code is compared with the last 4 bytes of the received upgrade package, and the comparison result is used as the check result.

And step A2, storing the upgrading program and writing the value of the upgrading mark as a first preset value.

As described above, the storage space of the memory 21 (e.g., flash) of the lower computer 20 includes three portions, which are the factory area 211, the backup area 212, and the upgrade area 213, respectively, where the factory area 211 is used to run the factory original program, the backup area 212 is used to receive the upgrade program firmware, and the upgrade area 213 is used to upgrade the running space of the program firmware.

After receiving the protocol header, the lower computer 20 stores the code before the protocol end in the backup area 212 of the memory 21 for analysis; thus, step a2 is to store the upgrade program in the backup area 212 and write the value of the upgrade flag to the first preset value. Specifically, if the verification result is that the verification is passed, indicating that the receiving is successful, the upgrade program is stored in the backup area 212; the verification is passed, that is, the real-time verification code is consistent with the last 4 bytes of the received upgrade package, and the lower computer 20 erases the upgrade program in the cache to the backup area 212, so that the cache can store a new upgrade program. Meanwhile, the lower computer 20 writes the value of the upgrade flag as the first preset value in a designated storage space, where the designated storage space may be the flag area 214 of the memory 21, or may be a storage space existing outside the memory 21. Illustratively, the value of the upgrade flag is written to be 1, that is, the first preset value is 1. The lower computer 20 sends return data to the upper computer 10 after storing the upgrade program and writing the value of the upgrade flag to the first preset value, and feeds back that the communication is successful. Correspondingly, the upper computer 10 executes step C4, receives the return data and stores the return data for easy viewing.

And A3, restarting the lower computer and detecting the value of the upgrading mark.

After the upgrade program is stored, specifically, after the backup area 212 completes the backup of the upgrade program, the lower computer 20 resets and restarts to end the running program, so as to prepare for the subsequent upgrade. After the restart is completed, the lower computer 20 first detects the value of the upgrade flag.

And step A4, if the value of the upgrading mark is the first preset value, acquiring the upgrading program and writing the value of the upgrading mark as the second preset value.

After the lower computer 20 is restarted, if the detected value of the upgrade flag is 1 (the first preset value), the upgrade program is acquired to perform subsequent processing, and the value of the upgrade flag is rewritten, specifically, the value of the upgrade flag is written as the second preset value, for example, 2.

In this embodiment, after the lower computer 20 is restarted, it detects that the value of the upgrade flag is 1 (the first preset value), copies the code of the backup area 212 to the upgrade area 213, thereby acquiring the upgrade program from the backup area 212, and then writes the value of the upgrade flag to the second preset value.

And step A5, running an upgrading program.

And the lower computer 20 acquires the upgrading program after restarting, and runs the upgrading program to realize upgrading.

In this embodiment, after the upgrade program is stored in the upgrade area 213, the lower computer 20 jumps to the upgrade area 213 to run the upgrade program, and runs the upgrade program stored in the upgrade area 213, thereby completing the upgrade, where the upgrade program runs normally. Further, the lower computer 20 transmits data indicating that the upgrade is completed to the upper computer 10; accordingly, the upper computer 10 executes step C5, receives and stores the data indicating that the upgrade is completed, and facilitates viewing.

As described above, the lower computer 20 receives the upgrade communication data, wherein the upgrade communication data includes the upgrade program; the lower computer 20 stores the received upgrade program in the backup area 212, and writes the value of the upgrade flag as a first preset value; the lower computer 20 restarts and detects the value of the upgrade flag; if the value of the upgrade flag is the first preset value, storing the upgrade program stored in the backup area 212 in the upgrade area 213 of the lower computer, and writing the value of the upgrade flag into the second preset value; the upgrade flag is a second preset value, which indicates that the upgrade area 213 stores the upgrade program, so that the upgrade program stored in the upgrade area 213 can be run; the first preset value is corresponding to the backup area 212 and stores the received upgrading program, the second preset value is corresponding to the upgrading program which is stored in the backup area 212 and copied to the upgrading area 213 after the lower computer 20 is restarted, the upgrading program can be reliably and continuously received and the upgrading can be completed, and therefore the upgrading can be stably carried out for multiple times in later maintenance; therefore, the remote upgrading can be carried out correctly, reliable remote upgrading is realized, technicians can be prevented from going to the field for processing, and the later maintenance cost can be saved.

Referring to fig. 6, the upper computer 10 of the present embodiment includes a mode switch 101. The mode switch 101 is a mode selection switch, and may be a toggle switch, such as a double toggle switch. In other embodiments, the mode switch 101 and the upper computer 10 are two independent components of the remote upgrade system.

Then, the remote upgrade method provided by this embodiment, fig. 7 is a logic diagram of the remote upgrade method provided by this embodiment, and referring to fig. 7, before the step a3 of detecting the value of the upgrade flag, a step B1 is further included.

Step B1, the state of the mode switch 101 is acquired.

The mode switch 101 has at least two states corresponding to a normal mode and an abnormal mode, respectively. The normal mode is a default state, and indicates that the lower computer 20 is operating normally. The abnormal mode is triggered by a user, for example, the gear of the mode switch 101 is shifted to the gear corresponding to the abnormal mode, which indicates that a problem, such as power failure or crash, occurs during the upgrade process. Step B1 specifically includes step B11 and step B12.

And step B11, receiving a state switching instruction sent by the user through the trigger mode switch.

When a user finds that a problem occurs in the upgrading process, the user toggles the mode switch 101 of the upper computer 10 and sends a state switching instruction to the upper computer 10, for example, the normal mode is switched to the abnormal mode. The upper computer 10 receives the state switching instruction and sends the state switching instruction to the lower computer 20.

And step B12, generating the state of the mode switch according to the state switching command.

After receiving the state switching instruction sent by the upper computer 10, the lower computer 20 generates the state of the mode switch 101 according to the state switching instruction.

Of course, the upper computer 10 may generate the state of the mode switch according to the received state switching instruction, and then transmit the state of the mode switch to the lower computer 20, so that the lower computer 20 acquires the state of the mode switch 101.

Referring to fig. 7, after the lower computer 20 is powered on again, the lower computer is a default factory program and then detects the state of the mode switch 101. Correspondingly, the detecting the value of the upgrade flag in the step a3 specifically includes: and if the state of the mode switch is the normal mode, detecting the value of the upgrading mark. The foregoing steps a4 and a5 are then performed.

Correspondingly, the step a5 (running the upgrade program stored in the upgrade area) is specifically: referring to fig. 6, if the value of the upgrade flag is not the first preset value but the second preset value, the upgrade program stored in the upgrade area 213 is operated.

After the status of the mode switch 101 is acquired, it is detected that the value of the upgrade flag is not the first preset value but the second preset value, and this indicates that the upgrade area 213 stores a new upgrade program and needs to be upgraded. Then, the lower computer 20 jumps to the upgrade area 213 to run the upgrade program.

Correspondingly, the remote upgrade method provided by this embodiment further includes step B2.

And step B2, if the value of the upgrade flag is neither the first preset value nor the second preset value, running the factory program stored in the factory leaving area 211 to receive the upgrade communication data.

Various interferences may occur in the process of upgrading the lower computer 20, which may cause an error in running the upgrade program. In order to avoid this possibility, the upper computer 10 is provided with a mode switch 101, and the remote upgrade method provided in connection with this embodiment may select a normal mode or run a factory program. Specifically, referring to fig. 6, in the case that the state of the mode switch is the normal mode, if the value of the upgrade flag is neither the first preset value nor the second preset value, it indicates that a problem occurs in the upgrade process, and for this reason, the lower computer 20 runs the factory program stored in the factory exit area 211, receives upgrade communication data, restarts the upgrade, or starts a new round of upgrade, and can implement multiple upgrades in later maintenance.

Further, referring to fig. 7, if the state of the mode switch is the abnormal mode, it indicates that a problem occurs during the upgrade process. And detecting whether the value of the upgrading mark is a second preset value or not in order to determine whether an error occurs in the upgrading process. If the value of the upgrade flag is the second preset value, it indicates that although a problem occurs in the upgrade process, the upgrade area stores the upgrade program to be updated, and at this time, the foregoing step a5 (running the upgrade program stored in the upgrade area) is performed. If the value of the upgrade flag is not the second preset value, it indicates that a problem occurs in the upgrade process and data in the upgrade area is lost, and in order to perform normal upgrade, a factory program stored in the factory leaving area 211 is run to eliminate the problem, so as to receive upgrade communication data. Thus, the system has good error recovery capability.
