摘要
针对目前绝大多数高校宿舍不能安全防火所带来的严重后果,设计了一套当宿舍发生火灾时,能自动报警的安防系统。系统利用烟雾和温度传感器采集宿舍内的烟雾和温度信息,通过放大后进行A/D转换,单片机对A/D转换数据进行计算,从而判断出宿舍是否安全。测试结果表明,当宿舍发生火灾时,系统能及时进行声光报警,通过GSM发送短消息通知相关人员,并打开电磁阀进行灭火,防止灾情恶化,达到预期效果。
Aiming at the serious consequences that the college dormitory can＇t fire safely brought,a set of safety system that can automatically alerts has been designed when a fire occurs in a dormitory.The system collects smoke and temperature signals through smoke and temperature sensors.The signals will be converted by the A/D converter after being amplified,then computed by SCM.The dormitory fire safety will be determined by the data.The test results showed that the system can timely alarm and send a short message through the GSM to notify the relevant personnel when a dormitory fires,and open the solenoid valve for fire fighting.These prevent fire degradation and achieve the desired results.
