本文主要介绍了葛洲坝二江电厂的计算机防误操作闭锁系统基本原理、功能、设计原则和应用效果;计算机防误操作闭锁系统主要由操作指令闭锁和操作程序闭锁两大部分组成;操作指令闭锁是通过“安全分析系统”来实现的,防止操作指令的误发;操作程序闭锁是计算机对设备操作过程中的每一项操作均实行严格的安全条件检查,防止由于各种因素引起的误操作。
This paper mainly introduces the basic principle, function, design principle and application effect of computer anti-misoperation locking system in Gezhouba Erjiang Power Plant. The computer anti-misoperation locking system mainly consists of two parts: operation command lockout and operation program lockout. The operation command lockout is Through the “safety analysis system ” to achieve, to prevent the mistakes of operating instructions; operating procedures blockade is a computer equipment operation in the operation of each operation are strictly stringent safety conditions to prevent due to various factors caused by errors operating.
