基于NB-IoT技术的井盖管理系统设计与实现

Design and Implementation of Manhole Cover Management System Based on Narrowband IoT Technology

井盖是地下管廊安全的出入口,是地下管廊运维不可缺少的组成部分。传统的井盖管理是采用人工巡检方式,但是由于井盖数量大以及分布不集中,管理起来比较困难,特别是当井盖出现破裂、移开、被盗等问题时不能及时发现,就会造成一定的安全隐患。本文提出了一种基于NB-IoT技术并集成多种传感器的智能井盖管理系统,该管理系统增加了电子锁功能和低功耗模式,使得实际应用价值得到很大提升。通过大量实验证明,该管理系统可以实时监控井盖的状态以及井盖环境信息,从而达到智能管理井盖的作用。

The manhole cover is the safe entrance and exit of the underground pipe gallery and it is an indispensable part of the operation and maintenance of the underground pipe gallery.The traditional manhole cover management adopts the manual inspection method,but due to the large number of manhole covers and the non centralized distribution,it is difficult to manage,especially when the manhole covers are cracked,removed,stolen and etc.,which cannot be found in time,resulting in certain security risks.This paper presents an intelligent manhole cover management system,which is based on NB IoT technology and integrates multiple sensors.Considering the application,the electronic lock function and low power design mode are added,so the practical application value is greatly improved.Through a large number of experiments,it is proved that the management system can monitor the state and environment information of manhole cover in real time,so as to achieve the role of intelligent management of manhole cover.
