高校宿舍远程安防监测系统设计

Design of the Remote Security Monitoring System for College Dormitory

针对高校宿舍火灾及物品被盗事件频发,设计了一种集火灾报警和防盗的远程监控系统。该系统采用LM3S811为核心微处理器、GSM作为远程无线传输模块、MQ-2烟雾传感器和DS18B20温度传感器作为火灾传感器件、热释电红外传感器作为防盗监测传感器,采用红外遥控的方式改变系统的参数设置,通过信号处理算法对宿舍内的环境进行判断,通过硬件系统测试,结果表明系统能够较快感知宿舍内的突发情况,能达到预期效果。

Aiming at frequent events of fire and theft occurred in college dormitory, a remote monitoring system combining fire alarm with anti-theft is designed. The system uses LM3S811 as the core microprocessor, GSM as the remote wireless transmission module, MQ-2 smoke sensor and DS 18B20 temperature sensor as the fire sensors, the pyroelectric infrared sensor as the anti-theft monitoring sensor, uses the infrared remote control way to change the parameter setting of the system. Through the signal processing algorithm the environment in dormitory is judged. The results of hardware system testing show that the system can quickly perceive the emergent situation in dormitories, and achieves the desired effects.
