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。
Aimed at the university dormitory fire and the frequent theft of goods, a fire alarm and burglar alarm system was designed. The system uses the LM3S811 as the core microprocessor, GSM as the remote wireless transmission module, the MQ-2 smoke sensor and the DS18B20 temperature sensor as the fire sensing device, the pyroelectric infrared sensor as the anti-theft monitoring sensor, and the infrared remote control method to change the system parameters Set, through the signal processing algorithm to judge the environment within the dormitory, through the hardware system testing, the results show that the system can quickly perceive sudden dormitory, to achieve the desired results.
