题 目： 电厂交直流低压供电屏配电支路监测系统 PAGE I 摘要 电力系统对当前人们的生产生活都具有重要意义，而在进行电力使用时，电力开关又是整个电网系统中至关重要的一环，对电力开关状态的监测在电力系统运行中是非常有必要且重要的。传统供电系统的开关设计复杂，这就导致合闸保护和后期的维护相当困难，并且在初期，仅有相应的开关功能并无法对各个支路的状态进行实时监测。 而随着电子技术和计算机信息技术的发展，电力系统也在发生着巨大的变化，而本文基于51单片机对电力系统开关状态检测系统进行了开发，通过串口通信实现了可远距离观看供电开关的状态，通过LCD显示屏可以让使用者更直观的对各个支路的开关状态进行了解。本文将整个系统分为检测端和显示端，分别采用一个单片机进行设计。 为了更真实的模拟实际使用的情况，本文分别通过Proteus进行了仿真验证并做了相应的实物进行验证，从仿真和实物的实际操作来看，本文所设计的开关状态检测系统完全达到了设计要求，能够成功对各个支路的开关状态进行监测的同时通过串口发送至另一端进行显示。 关键词：电网系统；开关检测；串口传输；状态显示  Abstract The power system is of great significance to peoples production and life at present, and the power switch is a crucial part of the whole power grid system when it is used, so the monitoring of the power switch status is very necessary and important in the operation of the power system. The switch design of traditional power supply system is complicated, which leads to the difficulty of closing protection and later maintenance, and in the initial stage, only the corresponding switch function can not monitor the status of each branch in real time. And with the development of electronic technology and computer information technology, electric power system are changing so much, and this article is based on 51 single chip switch state detection system in power system with the development, through a serial port communication to achieve the distant view of the power supply switch state, through the LCD display can let users more intuitive to understand each branch switch state. In this paper, the whole system is divided into detection end and display end, respectively using a single chip computer design. In order to more truly simulate the actual use of the situation, this paper respectively through Proteus simulation verification and do the corresponding physical verification, from the simulation and the actual operation of the real object, the switch state detection system designed in this paper completely
