就二滩木材过坝１∶５模型的计算机监测控制系统作了系统介绍．针对二滩工程电气控制系统具有控制点数多，数据采集点多，现场条件差，同时还要达到实时监测、控制的目的，该系统设计为上、下位机的结构，下位机采用ＳＴＤ工控机及可编控制器实现对现场的实时监测、图形显示、报表打印等． A systematic introduction was made on the computer monitoring and control system of Ertan wood over dam 1: 5 model. For the Ertan project electrical control system has many control points, data collection points, poor site conditions, but also to achieve real-time monitoring and control purposes, the system is designed for the upper and lower computer structure, the lower computer using STD IPC and Programmable controller real-time monitoring of the scene, graphics display, report printing.
