摘　　要：在依据低速率蜂窝网络的窄带物联网(NB-IoT)通信技术的基础上,实现对电容电池的电压和工作温度的监测。利用嵌入式ARM9带Linux操作系统结合A/D电压采集电路与DS18B20温度传感器作为数据采集平台,以及Qt图形界面现场显示数据,同时应用NB-IoT通信技术将数据上报云平台与PC服务器。测试终端结果表明:系统可以准确实现现场与远程电池电压与温度数据监测,据数据显示电压误差低于1%。系统运行稳定可靠,为现场监测和远程监测提供条件。On the basis of narrow-band Internet of things( NB-IoT) communication technology in low-rate cellular networks,voltage and operating temperature monitoring of capacitive cells are achieved. The embedded ARM9 band Linux operating system combined with the A/D voltage acquisition circuit and the DS18 B20 temperature sensor is used as the data acquisition platform,and the Qt graphical interface is used to display the data in the field. At the same time,the data is reported to the cloud platform and the PC server by using the NB-IoT communication technology. The test results show that the system can accurately realize field and remote monitoring the battery voltage and temperature data,and the voltage error is less than 1 % according to the data display. The operation of the system is stable and reliable,which provides conditions for field monitoring and remote monitoring.
