具有语音提示功能的倒闸自动操作控制器

A power-switch auto-operating controller with voice function

针对国内中小型变电所存在的时常发生带负荷误操作倒闸或有故障而不能即时准确操作倒闸等问题 ,从安全、可靠、即时准确而又经济的角度出发 ,提出了采用单片机AT89C51为核心的具有语音提示功能的倒闸自动操作控制系统的方案 ,并且给出一个具有四个主要用户的小型终端变电所的倒闸自动操作控制器原理框图。

In this paper,to counter the questions of mis-operation of power-switch with load or not taking of power-switch on time for middle and small domestic transformer substations,we give a project taking AT89C51 microcomputer as the core power-switch auto-operation control system with voice function,and present the operating principle,key part circuits and program flow charts of a small terminal transformer substation with 4 main users.We take into consideration safety,reliability,accuracy,instantaneity and economy.The controller makes middle and small domestic transformer substations run more safely.
