Dang Shi-hong

Abstract

To monitor the actual signal,this paper designs the multi channel data acquisition system with W77E58 as its core,presents its frame and the hardware and software implementation methods in analog acquisition.Besides,the detailed circuit diagram and software program are shown.Field tests show that the system has the advantage of high precision,low power consumption,strong anti-interference ability and good versatility.
