新型漏电火灾报警系统研制方案

Design scheme of a new leakage fire alarm system

针对国内外漏电火灾报警系统的总线传递线路架设困难和设计冗余,研制了基于PIC(Peripheral Interface Controller,PIC)单片机的新型漏电火灾报警系统,并介绍了新型漏电火灾报警系统的系统结构及功能设计.该系统通过人机界面操作以及检测数据信息的交流传递,实现了下位机与上位机之间的信息传递,克服了传统的总线传递线路应用相关方面的困难.较传统的漏电火灾系统,该系统具有结构简单、操作容易、通信简单的优点.

Based on the current situation of the electricity leakage fire alarm system at home and abroad , The development of a new scheme was proposed , which resolved the problem of the constructed difficul-ties of traditional bus transmission line , redundancy design , etc.The method of the design adopted PIC （ Peripheral Interface Controller , PIC ） single-chip microcomputer , and introduced the system structure and function , hardware circuit design and software design .Compared with the traditional leakage fire sys-tem, the design had the advantages of simple structure , easy operation, simple communication.This sys-tem solved hardware redundancy of traditional leakage fire system .Throughing a man-machine interface and the exchange of testing data and information , it realized the information transfer between lower com-puter and upper computer , which overcomes the related difficulties of the traditional bususage .
