Abstract:

There were too many required measurement analog quantities in the control system of Mobile Frequency Convertor, design the extended circuit of multi-channel analog quantity measurement can complete the job accurately and promptly to this problem. Use remote-calibrate method, written analog quantity measure program of the embedded system to accomplish the measurement job of multiple channel analog quantity. The process of calibrate was fast, simple and preciseness, it can be applied to calibrate and check of measure analog quantity in the industry field. Its easy to master for the relative engineering and technical personnel.

Key words: frequency convertor, embedded system, distributed control system, analog quantity measure
