基于单片机的配电箱温度监测和火灾报警系统设计

Design of temperature monitoring and fire alarm system of distribution box based on MCU

针对配电箱在夏季运行存在高温等情况,设计一种应用于配电箱的温度监控和火灾报警系统,以单片机为核心,使用温度传感器和烟雾传感器对配电箱内的环境进行检测,实现自动散热和火灾报警功能。使用无线网络模块将环境数据上传至OneNET物联网平台,实现对配电箱内运行环境的远程监控。实验结果表明:在夏季阳光下,环境温度36.7℃左右时,此系统最高可使封闭式配电箱降温6℃;发生火灾时,能够进行声光报警,同时远程物联网平台可以实时存储和显示温度和烟雾数据,供PC端和手机端访问查看。该系统能够满足配电箱内日常运行环境的实时监测以及突发火灾情况下的及时报警需求,方便用户或安全管理人员对配电箱进行安全智能管理。

In view of the high temperature operation of the distribution box in summer,a temperature monitoring and fire alarm system applied to the distribution box was designed.The system uses MCU as the core,and uses a temperature sensor and a smoke sensor to detect the environment in the distribution box to realize automatic heat dissipation and fire alarm.The wireless network module is used to upload environmental data to the OneNET Internet of Things platform to achieve remote monitoring of the distribution box.The experimental results showed that in summer,when the ambient temperature is around 36.7℃,the temperature of the enclosed distribution box can be dropped by up to 6℃.When a fire occurs,it can provide sound and light alarms,and the remote IoT platform can store and display temperature and smoke data for PC and mobile phones to access and view.The system can meet the need for real-time monitoring of the environment in the distribution box and the timely alarm in case of fire emergency,which is convenient for users or safety management personnel to carry out safe and intelligent management of the distribution box.
