煤矿供电系统的保护设计软件设计

摘要

单片微型计算机简称单片机。它是把组成微型计算机的各功能部件：中央处理器、CPU、随机存取存储器RAM、只读存储器ROM、I/O接口电路、定时器/计数器以及串行通信接口等制作在一块集成芯片中，构成一个完整的微型计算机。单片机主要应用于控制领域，由于其具有可靠性高、体积小、价格低、易于产品化等特点，因而在智能仪器仪表、实时工业控制、智能终端、通信设备、导航系统、家用电器等自控领域获得广泛应用。

煤矿供电系统保护是整个煤矿安全的重要组成部分，做好煤矿供电系统保护工作是做好煤矿安全工作的保障之一，对避免和减少煤矿井下重大安全事故的发生具有十分重要的作用。

在煤矿生产中，井下煤矿的供电系统的保护大多采用继电保护装置，随着计算机技术、微电子技术、信息技术、网络通信技术的不断发展，智能保护系统已经研制成功，这使得使整个系统的可靠性有很大提高，从而保证了生产质量。

Abstract

Single chip computer chip referred to. It is composed of the microcomputer functional components: the central processor, the CPU, random access memory (ROM, RAM and read-only memory I/O interface circuit, timer/counter and serial communication interface chip in a piece of integration, constitute a complete micro computer. SCM is mainly applied to control field, since it has high reliability, small volume, low price, easy to prod in intelligent instrument, industry control, real-time intelligent terminals, communication equipment, navigation, household appliances automation field widely used.

Coal is the power system protection is an important part of coal mine safety in coal power system protection, ready to work is the guarantee of coal mine safety work, to prevent and reduce the colliery safety accidents of major plays a very important role.

In coal mine production in coal mine, the power system protection relay protection device is used mostly, along with the computer technology, microelectronics technology, information technology, network communication technology unceasing development, intelligent protection system has been developed, which makes the whole of the reliability of the system has greatly improved, so as to ensure the quality of production.

Keywords: MCU ；A \ D converters；D/A converter
