基于NB-IoT与单片机的组合式电气火灾探测器设计与实现

Design and implementation of combined electrical fire detector based on NB-IoT and MCU

为预防电气火灾事故,以STM32F103VCT6单片机为主控制器,以NB-IoT为通信模块,设计开发了组合式电气火灾探测器。探测器采集到用电设备及输电线路的短路、开路、过欠压、过电流、温度异常和漏电等故障信息,会立即发出声光警报且显示其报警信息,并将信息同步上传到物联网平台,通过计算机与手机将报警信息及时推送给用户,并对其进行远程监管。结果表明,电气火灾探测器反应灵敏,稳定性高,设备运行稳定。

In order to prevent electrical fire accidents,a combined electrical fire detector is designed and developed with STM32F103VCT6 as the main controller and NB-IoT as the communication module.The detector collects fault information such as short circuit,open circuit,over-voltage,under voltage,over-current,temperature abnormality and leakage of electric equipment and transmission lines,will immediately send out an audible and visual alarm and display its fault information on the screen,and simultaneously upload the information to the Internet of things platform,push the fault information to the user in time through the computer and mobile phone,and conduct remote supervision on it.The test results show that the electrical fire detector is sensitive,stable and the equipment operates stably.
