摘　　要：针对目前气体泄露检测报警装置存在检测精度低、报警方式单一等问题,设计一种便携式CO气体泄漏报警仪。报警仪以MSP430F135芯片为控制核心,以声光、震动、短信模块为报警主体,通过CO传感器获得CO体积分数,经过数据去噪、放大、A/D转换、安全验证、报警触发和实时显示等流程完成气体泄漏的实时监测和处理。为了同时满足安装和便携两种方式,内置了外置供电和充电模块自动切换,实时显示电量和提醒充电,经过实验室测试和现场测试,该气体报警仪具有便捷、高精度、低功耗、多模式报警、操作方便等多种优点。Aiming at issues exist in gas leak detection and alarm device leak such as detection precision is low, alarm mode is single, design a portable CO gas leak alarm device. The alarm uses MSP430F135 chip as control core,use sound and light,vibration, SMS module as alarm body, CO volume fraction is obtained by CO sensor, through data de-noising, amplification, A/D conversion, security authentication, real-time display, alarm trigger and other processess to complete real-time monitoring and processing of gas leak. In order to both satisfy two ways of installation and portability,buih an external power supply and charging module automatically switches, real-time display battery charge and reminders, through laboratory and field test ,the gas alarm device has convenient, high- precision, low power consumption, multi-mode alarm, easy to operate, and other advantages.
