摘　　要：介绍在DCS系统中对交流电气量进行直接采集的应用方法,重点介绍可直接应用于DCS系统中的多通道交流量采集模块的设计原理,给出系统设计框图,并以交流电压测量模件为例,给出交流电压测量模件原理框图,简要介绍其工作流程。This article presents an application for sampling and measuring the Alternating Current （AC） signal in the Distributed Control System （DCS） and the design principle of the multi-channel AC sampling module which can be applied directly in DCS in detail. It shows the whole system design scheme by functional block diagram. Then the module for measuring akemating voltage is introduced as example. A block diagram for the module is given and simply describes how it works.
