Research and application of control system of magnetic-vibrant-thermal therapy apparatus based on WinCE

In recent years, it was proven that the apparatus integrated with pulse magnetic field, vibration and heating three physical factors can obtain positive curative effects. This paper presents a friendly and accurate control system based on WinCE for magnetic-vibrant-thermal (MVT) therapy apparatus. The system mainly consists of four modules including data processing, real-time control, graphical interface and system maintenance. Specially, a fast approximate piecewise linear interpolation method is proposed to real-time convert and calibrate the sensor parameters, and a fault-tolerant communication protocol with a self-check and multi-device control function is proposed to exchange data and commands through serial interface and network protocol. Experimental results show that the therapy apparatus can accurately and real-time control the output of physical factors, and has well operability, timeliness and reliability.
