摘　　要：该系统利用MCS-51单片机8031为核心构成的数据采集模块进行数据采集,通过调制解调芯片MSM7512BRS与标准MODEM建立连接,采用公共电话网络作为数据传输信道,将数据传送到中央管理计算机进行综合处理。其中数据采集模块与中央管理计算机的远程通信是该系统实现的关键点之一,本文主要介绍系统的远程通信问题,详细说明了调制解调芯片MSM7512BRS与标准MODEM的连接过程。A remote electric energy management system based on the public switched telephone network is introduced. First the data is gathered by the data-gather-module designed with 8031 of MCS-51 single chip computer. Then the chain of the data is set up by the modem chip MSM7512BRS and MODEM. Last using the public switched telephone network as the data transmission channel, the data is transmitted to the cen-tral computer to process synthetically. One of the key techniques is the remote commu-nication between the data-gather-module and the central computer. This paper intro-duces the technique of the remote communication mainly, and the process of setting up chain of the data between the MSM7512BRS and MODEM is introduced in detail.
