摘要
面向智能城市感知需求,设计了用于电网线路健康状态监测的多参数NBIoT传感监测终端。终端以STM32L低功耗嵌入式系统为核心,基于由DS18B20测温芯片、DHT11感湿器件、BH1750光照检测芯片、LSM303DLHC微加速度计、L3G4200微陀螺仪组成的传感器阵列监测线路多参数,并通过NBIoT BC95模块和UDP协议实现物联网传输。监测设备能够实时传感电网环境的温湿度、光照度、振动倾覆状态等,并与云服务器交互。测试表明,该终端在未来城市输电监管应用中具有实用价值。
A NBIoT monitoring terminal device sensing environment parameters of electrical grid transmission line was designed and realized. The terminal is based on STM32 L embedded system,DS18 B20 thermometer,DHT11 humidometer,BH1750 illuminometer,LSM303 accelerometer,L3 G4300 gyroscope and BC95 module which can realize NBIoT communication were used. The device can monitor environmental parameters and operating condition of transmission line,with communication to network cloud server. Test shows that the terminal device is useful in future city transmission line monitoring.
