基于ARM的火灾报警系统的设计
摘要
火灾探测报警系统的出现增强了人类发现火情的能力,降低了火灾的危害。但传统火灾探测报警系统的综合分析判断能力较差,通信能力弱、火灾误报和漏报时有发生,系统性能还有很大的提高空间。
本文详细介绍了一套基于ARM的火灾报警系统的设计,该系统将目前广泛使用的嵌入式技术与火灾探测技术结合在一起,采用网络通信作为信息传输手段,实现了火灾探测报警功能。同时,还将嵌入式视频监控系统引入该系统中,用于提高系统应对火灾误报的能力,降低火灾误报带来的损失。
文中重点讲述了系统硬件结构、嵌入式开发环境构建、基于ARM一Linux的GPIO驱动程序的设计、火灾探测和网络传输应用程序的设计、嵌入式视频监控系统、基于LabVIEW设计的上位机火灾监控平台的设计等内容。

Abstract
Over the years, the mine safety accident frequency sent. When analysis in the near future several coal mine especially big accidents discovers several general character question: The ground and the mine shaft personnel's munication is not prompt; After the coal mine accident occurs, the emergency disaster relief rescues safely the efficiency is low, search and rescue effect difference .In order to difficult to occur after the ore can confirm rapidly the ore difficult position and is stranded the staff population, by the quickest speed development rescue operations, safeguards miner's safety, arranges in the mine pit based on the high technology and new technology safe monitoring management system management system imperative. This article has designed one based on the CAN main work and the radio frequency recognition technology mine pit positioning system .Uses RFID to be possible real-time the staff who wears electronic label (Tag) to the mine shaft to carry on the localization, the status recognition, gathers the information from the reader-writer to transmit the ground through the CAN main line, on the one hand has realized and under personnel's checking attendance statistics, on the other hand distributed the situation for the inquiry mine pit in personnel to provide the basis. In the system design the use brings ECAN module PIC monolithic integrated circuit PIC18F4580 and the radio frequency receiving and dispatching chip ADF7020 achievement writes the pone
