基于NB-IoT的智慧巷道水位监测系统研究

Research on Water Level Monitoring System of Intelligent Roadway Based on NB IoT

研究提出一个基于NB-IoT技术的物联网巷道水位监测系统架构及模型设计,尝试将传感网技术应用于解决巷道水灾的监测问题上。系统利用树莓派作为传感节点中各监测节点的控制核心,收集、过滤巷道周边传感器获取的信息,并通过传感网传递信息给后台服务器,记录所有水位信息与处理结果。系统包含一个能够识别出水位信息的传感网络模型,通过架设于巷道中的传感器网络去感知水位情况后,通过NB-IoT网络传递信息,记录异常信息与处理结果,如果出现信息异常,传感节点可自动报警。

The paper proposes an architecture and model design of water level monitoring system for IoT roadway based on NB IoT technology,and try to apply sensor network technology to solve the monitoring problem of roadway flood.The system uses raspberry pie as the control core of each monitoring node in the sensor node to collect and filter the information obtained by the sensors around the roadway,and transmits the information to the background server through the sensor network to record all water level information and processing results.The system includes a sensor network model that can identify the water level information.After sensing the water level through the sensor network set up in the roadway,the system transmits information through the NB-IoT network,records the abnormal information and processing results.If the information is abnormal,the sensor node can automatically alarm.
