The Research Of Performance Test And Fault Diagnosis System Of Water Pump In The Coal Mine Underground

This subject is the study of the pump tests and failure diagnosis system, reducing the incidence of accident miners,and providing the scientific management of the parameter for the submersible pump.The pump performance test includes the three parts of the software, the hardware design and emulation, the diagnose system of the pump introduced the main axis of the detection programme.The pump tests of the hardware design is based mainly on the overall plan and select module functionality of their hardware counterparts, Mainly including the data collection, and the serial communication systems, the key electrical circuits and the LCD display section design.According to the hardware and system design principle a performance test the PCB board, and debugging appears to confirm the correctness of the board.The software design is the use of the software development system Keil uvision4 C51,the program include the application procedures and the data collection, processing the application, application programs, showing a list and the serial communication a subroutine.The data collection with a subroutine is collecting the flow of pump capacity,pump head,active power of pump and pump speedThe emulation software is the proteus monolithic integrated circuits, and peripheral devicing of the simulation debugging, to verify the accuracy of the system works and rationality need to make the experiment.The pump to diagnose the system is established to detect, to force the monolithic integrated circuits to control the core set of the system, according to the scheme set out in the hardware and software design of the main pointsFigure [46] table [15] reference [41]...
