摘　　要：给出一个用于变电站二变三遥系统中的实时多任务分布式远程工业控制计算机通信网的设计方案。该方案使用了ＢＩＴＢＵＳ、ＳＴＤ和ＰＣ三种标准总线及工控语言ＰＬ／Ｍ５１、Ｃ语言和汇编语言等三种语言编程，具有形式新颖、技术先进和指标较高等特点。主站备份切换时间大大缩短，可达３秒．这种方案将被广泛应用。his paper present an advanced design scheme for the computer Communication Network based on BITBUS. STDBUS and PCBUS that used in The Three Remote System of electric power sencond substation.This Scheme is an excellent New and practical design scheme that used PL/M51 Industrial Control language. C and assembly language in the pragram. The switch time between main station and standby station is 3S. The utilization of this type of communication Network Could be the orientation of further development for the design of industrial Control Network.
