摘　　要：随着自动化技术的不断发展,仪表技术与自控系统也不断向智能化、网络化方向延伸。首先对变电所倒闸操作监测系统总体结构设计进行了研究,重点介绍了下位机控制单元各部分模块及其功能,并且给出了倒闸操作的系统组成框图,关键部分电路及系统流程图。在倒闸操作模拟系统中,以STC单片机为主控制器,通过与上位机进行串行通讯,接收上位机发出的运行状态显示和开关运行方式改变各种命令,实现对马赛克模拟屏上的所有模拟显示开关实现控制功能。With the rapid growth of automatic technology, meter technology and automatic system also constantly change to the way of intelligent and network. This paper provided the overall structural design of the power-switch operating monitoring system, and based on it it introduced chiefly each module and function in the upper control unit. It presented the composition chart ,the key circuits and program flow charts of power-switch operating system. In the power-switch operating analog control system, using STC MCU as the main controller, it managed the upper computer, then realized serial communication. The lower control unit received the running status display and the switch operating mode from the upper computer software to change any order. It can achieve to manage all the analog switch displays in the mosaic analog panel.
