Abstract
The paper studies on measurements of air-gap magnetic suspension system suspension system installation. Measurement of suspended air-gap magnetic suspension system installed in the entire system plays a part in measurements, display and feedback。 The design takes the control of single-chip core PIC16F877A as the test board,and with the function of keyboard,the test board converse the three input signals to the measure of the suspension of air-gap,the controlled voltage and the controlled current,which realize the processing and storage of the sampling data,only to display the measured data through the RT-12864-10 LCD,and the RS232 port can also send the data to the PC. The characteristics of this design is having made a low-cost,high-precision measurement system by taking PIC single-chip as the core,which settle a foundation of a more in-depth application of the magnetic levitation technology in the coming days.
