1) various data during the operation of the lift pump are acquired through a first angle sensor, a temperature sensor, an infrared receiver and a second angle sensor in a unit monitoring and acquiring device;

2) analyzing the collected various data through a CPU (central processing unit) of the processor, thereby obtaining relevant parameters of the rotating speed stability, the operating temperature, the position deviation and the flow deviation of the oil transportation branch pipe and the oil transportation main pipe of the lift pump;

3) the related parameters obtained through analysis are wirelessly transmitted to the internet remote terminal through the wireless transmission module, the internet remote terminal stores the related parameters, meanwhile, the failure reason of the lifting pump is sent to an operator according to the related parameters, and the operator is reminded to carry out related maintenance.
