The friction and the abrasion are main factors influencing the working reliability and the service life of mechanical equipment, various running machines are kinematic pairs consisting of various friction pairs, and the friction and the abrasion are inevitable during the running process, which are main forms of component failure and failure. The grinding particles are the inevitable product of the abrasion of the friction pair in the equipment and also the main source of oil pollution, and the generation of the grinding particles can aggravate the abrasion of the friction pair and even generate larger abrasion. The wear particles suspended in the lubrication system are important information carriers reflecting the wear state inside the equipment. Taking a fan as an example, the current device state detection method is to analyze the lubricating oil in the device by means of on-site sampling, off-line detection and analysis, so as to determine the state of the device. This way, work load is big and when confirming that need more lubricating oil, equipment has adopted the more lubricating oil work of particulate matter for a long time, and there is longer time difference between sampling time and the change time promptly to accelerate the loss of equipment.

Based on this, the present embodiment determines the state of the device by detecting the interference signal generated by the lubricant on the sensor in real time, so as to avoid the situation of time delay caused by field sampling and offline analysis.

Specifically, as shown in fig. 1, an embodiment of the present invention provides an apparatus status analysis method based on lubricant oil information. The embodiment can be applied to a server, a processor corresponding to various detection platforms or a central controller of other detection systems.

In the application process, the embodiment includes the following steps:

and S11, obtaining disturbance information corresponding to the lubricating oil on the second equipment.

In the embodiment of the present application, the second device is a device or a plurality of devices currently being detected. The lubricating oil is the lubricating oil in the device being tested, i.e. the lubricating oil that has been added to the device. The disturbance information is a signal generated by the lubricant on the second device as it flows past the sensor. Specifically, the lubricating oil on the second device is pumped to the sensor through the pipeline by the oil well pump with a preset size, so that when the lubricating oil flows through the sensor, the particulate matters in the lubricating oil interfere with the signal generated by the sensor, for example, the continuous signal becomes a discrete signal. Specifically, an interference signal is generated on a magnetic field of the induction coil, the magnetic conductivity of the sensor coil is changed, and the material, size and quantity of friction particles carried by lubricating oil are detected by disturbing different changing conditions. Wherein the sensor is a particle sensor which transmits data to the central controller through an RS485 data communication interface. The oil-well pump of predetermineeing the size is small-size oil-well pump, and its effect is on pumping oil to particle sensor. The embodiment adopts the mode of small-size oil-well pump, makes it can adapt to the limited equipment in space, for example the gearbox casing. In the application process, the small oil well pump is placed outside the wind motor gear box and adjacent to the sensor.

In some embodiments, to achieve the automatic detection of the particulate matter in the lubricating oil, before performing step S11, the method further includes the following steps:

firstly, a plurality of first devices are numbered to obtain a first code of each device. All the devices which need to be detected by a worker during the first device are individually numbered, so that different numbers exist in each device, and the numbers are used as first codes. And meanwhile, setting standard index data of each first device. The standard index data may be data of particulate matter in the lubricant oil that may cause equipment damage during operation of each piece of equipment analyzed from previous operational data. The standard index data for each device may not be the same, depending on the type of device and the operating principle. And then, constructing an association relation between the first code and the standard index data, even if the number of each device is associated with the standard data, for example, when the number A0 is obtained, the standard index data corresponding to the number A0 can be called quickly, so that the data calling time and the accuracy of a calling result are saved. In the present embodiment, the device number, the standard index data, and the association relationship between the two are stored in the designated database.

In some embodiments, the disturbance information corresponding to the lubricant on the second device is also obtained, and a second code of the second device is also obtained. The second code is the code currently detecting the device, and the code may be received from the human-computer interface, for example, when the lubricant detection needs to be performed on the fan device, the worker data the code B0 of the fan device through the human-computer interface. According to the embodiment, the device code being detected is obtained, so that the subsequent data can be accurately called conveniently.

And S12, calculating index data of the lubricating oil on the second equipment according to the disturbance information.

According to the embodiment of the application, the corresponding index data is obtained by calling the prestored calculation program through the disturbance information acquired in real time. The function of the calculation program is to convert the disturbance information into index data containing the content of particulate matter in the lubricating oil, the type of particulate matter, and the size of particulate matter. The types of particulate matter include ferromagnetic particles and non-ferromagnetic particles, among others.

And S13, acquiring standard index data of the lubricating oil.

In the embodiment of the application, the corresponding first code in the database is matched through the previously acquired second code, and the standard index data of the lubricating oil on the second device is called according to the first code obtained through matching, so that the accuracy of the data calling result is ensured.

And S14, comparing the size relationship between the index data and the standard index data, and judging the equipment state according to the comparison result of the size relationship.

In the embodiment of the application, whether the particulate matters pinched by the lubricating oil on the second equipment exceed the preset value is determined through the size relation, and when the particulate matters are determined to exceed the preset value, the alarm information comprising the second code and the current state of the lubricating oil in the second equipment is generated. The alarm information can be sent to the mobile phone terminal of the corresponding worker in a short message mode, and can also be played on the corresponding terminal equipment in a sound mode. After receiving the alarm information, the working personnel can quickly determine the working state of the equipment and timely process the equipment so as to prolong the working time of the equipment.

In some embodiments, when the method is applied to a detection process of a wind turbine device, as shown in fig. 2, the method specifically includes the following steps:

the lubricating oil dirt detection sensor is controlled to detect the state of the lubricating oil in the fan, then the central controller calculates the pollutant index according to the detected state information of the lubricating oil, and a worker can check the pollutant index in real time through the control console or the mobile equipment. Then, the central controller judges whether the pollutants in the lubricating oil exceed the standard or not, if so, alarm information containing equipment numbers and equipment exceeding conditions is generated and sent to a specified terminal, so that a worker can receive specific information through a console or a mobile device to timely perform lubricating oil smoothness on the equipment; if the standard is not exceeded, whether the standard is exceeded or not is determined, the equipment number which is exceeded quickly and the condition of lubricating oil in the equipment are sent to a specified terminal, so that workers are reminded to pay attention to the equipment, and the lubricating oil is replaced in time when problems occur.

In conclusion, in the application process of the embodiment, the field sampling of workers is not needed, and when the lubricating oil is determined to be required to be replaced, the time difference between the sampling and the replacing of the lubricating oil is shortened, so that the lubricating oil on the equipment can be more slippery in time, and the service life of the equipment is prolonged.
