基于NB-IoT的无线数据采集器设计

Design of wireless data acquisitor based on NB-IoT

针对工商业燃气用量大、用户地域分散、抄表困难以及通过GPRS和4G网络抄表功耗大等问题,该文设计了一种基于NB-IoT的无线数据采集器,具有远程抄表、远程充值、远程阀控、告警主动上报等功能。实验及测试结果表明,所设计的无线数据采集器具有性能稳定、功耗低的优势。

Aiming at the problems of large industrial and commercial gas consumption,geographical dispersion of users,difficulty in meter reading,and high power consumption through GPRS and 4G networks,a wireless data acquisitor based on NB-IoT is designed.It has functions such as remote meter reading,remote recharge,remote valve control,and active alarm reporting.The experiment and test results show that the designed wireless data acquisitor has the advantages of stable performance and low power consumption.
