Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In this embodiment, the outer size of the spacer 3 is adapted to the inner wall size of the outer cover 9, and the spacer 3 is movably connected to the outer cover 9 through the reset spring 2; the microcontroller 703 includes an H-bridge motor drive circuit, a data storage circuit, a current detection circuit, an LED indication circuit, a 485 communication circuit, a 485 sensor circuit, a power supply step-down circuit, a logic control chip circuit, and a main control chip circuit; two types of chips are used to communicate with each other to control the sensor collection and the linkage with the refueling equipment. The STM32F030 MCU is used for logical operation, and the sensor values ​​are collected for comparison and communication. The host computer 485 communication and STM32F103 MCU are used for main control. The power step-down circuit provides stable power supply for the device to drive the motor and MCU to run. The main control MCU obtains the current vibration, temperature, and ultrasonic values ​​through 485 every 1 second. The user can send corresponding commands through 485 communication to query the current sensor data in real time, and control whether the filling action is needed by analyzing the sensor data, and can send some operating parameter information and control parameters through 485. The H-bridge motor drive circuit is used to drive the execution motor to move back and forth left and right for filling. The weak current signal is amplified by the operational amplifier through the current detection circuit, and the current current is obtained by obtaining the amplified voltage value. The corresponding operation is performed to obtain the current current. If the current is greater than the switching current, it is considered that the injection is completed. After each injection, the operating parameters are saved through the data storage circuit. The data storage circuit is used to store the operating data and parameters. If a single stroke operation times out and still times out after fault tolerance, the host computer will be informed of the error through 485, accompanied by a buzzer prompt and LED display. The logic control chip can replace the host computer to perform logical operations and send control commands for refilling.

At the same time, it is necessary to have the machine's own fault alarm prompt, temperature, vibration, ultrasonic alarm prompt and bearing mechanical fault alarm, and the automatic lubricating oil filling device is flexible to install, free from the constraints of the background, and is more convenient to use. It also has monitoring and analysis functions, automatically fills oil products according to the operating status of the equipment, reduces the oiling cycle, and ensures normal lubrication of the equipment; the microprocessor system is used according to the state, and can accurately measure the motor operating temperature, vibration and ultrasonic values, and detect the operating status of the equipment in real time, so as to achieve intelligent lubrication; and to ensure that each lubrication point is safe and reliable in performing grease injection and management, the lubrication pump has a 485 communication function, which can communicate wirelessly or wired data interactively, expand the use of system software, and realize centralized management of scattered equipment, and at the same time has remote data monitoring of equipment operation and lubrication status.
