基于NB-IoT的地下管网数据采集仪设计
Design of Underground Pipe Network Data Acquisition Instrument Based on NB-IoT
摘要
Abstract
Aiming at the difficulties in water quality data collection and outdated monitoring methods of the underground pipe network,a data acquisition instrument based on NB-IoT is designed.The data acquisition instrument uses STM32L151RET6 low-power chip and NB-IoT communication module,uses MOS tube to control the on and off of peripher-al power supply.In software design,the microcontroller uses timed sleep and interrupt wake-up modes of operation to re-duce operating power consumption.The experimental results show that the data acquisition instrument runs stably,and the data transmission conforms to the HJ212-2017 protocol.The average working current in the working state,receiving state and dormant state are 94 mA,9 mA and 300 pA respectively.And the use time of one charge is about 134 days.It can be applied to real-time monitoring of factory sewage pipes and urban underground pipe networks.关键词
