| Abstract: | A testing terminal is introduced, which is a highly accurate, miniature device for faint signal based on AD7718. On the basis of the analysis of the whole system, this paper describes the main hardware design points of the data collection module, and offers the software design procedure of the system terminal. The host computer system is developed based on / Windows98/2000/xp platform. Finally, combining the actual project requirement, this paper describes the main design points of anti-interference, and pointes out some special anti-interference measures. The precision of system testing is up to 0. 0017%. |
