摘要
以单片机作为控制器件,采用烟雾传感器、温度传感器设计火灾报警系统,实现实时监控.当温度或烟雾浓度超过设定的阈值1时,GSM模块向用户发送预警短信,同时启动声光报警,排气扇工作.当温度或烟雾浓度超过设定的阈值2时,GSM模块向用户拨打报警电话.系统主要有电源模块、烟雾检测、温度检测、矩阵键盘、液晶显示、声光报警、GSM模块、串口通信和数模转换等电路.该系统投入运行并测试后,可满足多种环境火灾报警的基本要求.
The design takes the MCU as the control device,and uses smoke sensor and temperature sensor to realize real-time monitoring.When the temperature or smoke concentration exceeds the first threshold,the GSM module sends a warning message to the user,and starts the audible and visual alarm and exhaust fan operation.When the temperature or smoke concentration exceeds the second threshold,the GSM module calls the user for an alarm call. The system mainly has power supply module,smoke detection,temperature detection,matrix keyboard,liquid crystal display,sound and light alarm,GSM module,serial communication and digital-analog conversion circuit.After the system is put into operation and tested,it can meet the basic requirements of fire alarm in a variety of environments.
