Embodiment Construction
[0031] The technical solution of the present invention will be specifically described below in conjunction with the accompanying drawings.
[0032] refer to figure 2 , the automatic lubricating device 4 has a man-machine interface self-setting lubricating work mode: (1). Manually set the lubricating operation time, injection amount and other information through the button 6, and display the operation process on the OLED display 5; (2). When When the sensors 2, 3 and another temperature sensor on the control circuit board 12 detect the information and evaluate that there is no overrun prompt, the whole set of lubricating device 4 implements drive control to the piezoelectric pump 13 according to the set information, and oils and lubricates; (3) .When the manual setting operation is not performed, the lubricating device 4 is filled with oil and lubricated according to the default information of the system.
[0033] A lubrication working mode based on sensor data fusion process...
