Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] In this embodiment, preferably, the control module is electrically connected to a power supply module for powering the system, and the power supply module is electrically connected to the mains power grid. The system is powered by the power supply module, so that the system can operate stably.

[0021] In this embodiment, preferably, the power supply module includes a step-down circuit for reducing high voltage, the power supply module includes a rectifier circuit for converting AC voltage into DC voltage, the power supply module includes a voltage stabilizing circuit for stabilizing and stepping down the voltage, and the power supply module includes a filter circuit for filtering out AC voltage from DC voltage. Through the step-down circuit, rectifier circuit, voltage stabilizing circuit and filter circuit in the power supply module, the supply voltage is regulated, the stability of the supply voltage is maintained, and the safety of the system circuit is improved.

[0022] In this embodiment, preferably, the control module is electrically connected to an auxiliary module, the auxiliary module includes a display screen for displaying data information, the auxiliary module includes a key unit for control and adjustment, the auxiliary module includes a timing module for timing and marking time, and the auxiliary module includes a storage unit for storing data information. The setting of the auxiliary module can improve the operational convenience of the system, the key unit facilitates the operation and control of the system, and facilitates the display of various data information, the timing module facilitates the time tagging of the data information, and facilitates query, and the storage unit is used to store the data information.

[0023] In this embodiment, preferably, the processing module includes a receiving unit for acquiring data information, the processing module includes a gain unit for amplifying the data information, the processing module includes a conversion unit for performing analog-to-digital conversion on the data information, and the processing module includes a filtering unit for filtering out interference from the data information. The data information is pre-processed through the receiving unit, gain unit, conversion unit and filtering unit in the processing module, thereby improving the precision and accuracy of the data information and facilitating calculation and processing of the data information.

[0024] In this embodiment, preferably, the detection module includes a moisture detection sensor for detecting the moisture content in the hydraulic oil, the detection module includes a viscosity sensor for detecting the viscosity of the hydraulic oil, the detection module includes a particle size sensor for detecting the particle size in the hydraulic oil, the detection module includes a temperature sensor for detecting the temperature of the hydraulic oil, the detection module includes a pH sensor for detecting the pH of the hydraulic oil, and the detection module includes a flow rate sensor for the flow rate of the hydraulic oil. The flow rate sensor is installed on the hydraulic oil delivery pipeline. Through a variety of detection sensors, the performance of the hydraulic oil is detected and various data information of the hydraulic oil is obtained. The viscosity standard is 10-6m2 / s±15%, the moisture content cannot exceed 0.03%, and the hydraulic oil must be changed if the water content exceeds 0.1%;

[0025] The acid value of lubricating oil has a significant impact on its performance. A high acid value indicates a high content of organic acids in the lubricating oil, which may cause corrosion to mechanical parts, especially in the presence of water. Furthermore, as lubricating oil oxidizes and deteriorates during storage and use, the acid value gradually increases. The change in acid value is often used to measure the oxidation stability of lubricating oil or as an indicator for oil changes.

[0026] The impurities separated by filtration from the precipitation and suspended matter in the lubricating oil that are insoluble in gasoline or benzene are called mechanical impurities.

[0027] Mechanical impurities in lubricating oil are mainly foreign matter mixed into the lubricating oil during use, storage and transportation, such as dust, mud, sand, metal debris, metal oxides and rust.

[0028] The presence of mechanical impurities in lubricating oil will accelerate the wear of mechanical parts such as grinding, straining and scratching, and block the oil nozzles and oil filters, causing lubrication failure. Mechanical impurities in transformer oil will reduce its insulation performance.

[0029] Large particles greater than 20 microns can cause catastrophic failure; particles with a clearance size of 10-25 microns can cause the greatest wear and filter / servo valve plugging.

[0030] Temperature sensors are used to detect the temperature of hydraulic oil during operation. When the temperature is low, the viscosity is too high, making startup difficult. Furthermore, after startup, the lubricating oil will not flow easily onto the friction surfaces, causing wear on mechanical parts. If the temperature is too high, the viscosity decreases, making it difficult to form an appropriate oil film on the friction surfaces, resulting in a loss of lubrication and causing problems such as rubbing and gluing on the friction surfaces of mechanical parts. Therefore, the oil must have a good viscosity-temperature characteristic, meaning the smaller the change in viscosity with operating temperature, the better.

[0031] The flow rate sensor is used to detect the delivery flow rate of the hydraulic oil to prevent the hydraulic oil viscosity or impurities from being too high, causing the hydraulic oil to be unable to be delivered or to be delivered slowly, resulting in low lubrication between mechanical meshing.

[0032] In this embodiment, preferably, the communication module adopts a 5G network, a wireless network or a Bluetooth network, and transmits data information through the communication module, and selects the communication method according to the length of the distance.

[0033] Working principle: When the hydraulic oil is working, the control module sends a monitoring instruction, or the terminal module sends a monitoring instruction through the communication module. The monitoring instruction is transmitted to the drive module through the processing module. The drive module controls the micro oil pump to extract the hydraulic oil in the hydraulic oil tank, and then detects the hydraulic oil through the moisture detection sensor, viscosity sensor, particle size sensor, temperature sensor, pH sensor and flow rate sensor in the detection module, and transmits the detected data information to the processing module. The data information is pre-processed by the processing module to improve the precision and accuracy of the data information, which is convenient for calculation and processing of the data information. The control module analyzes and processes the data information, analyzes the quality of the hydraulic oil, and transmits the data information to the display screen in the auxiliary module for display, and the data information is time-stamped through the timing module for easy query after storage in the storage unit, and then the data information is transmitted to the terminal module for decision-making and processing of the hydraulic oil.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
