摘　　要：城市地下管廊内布设了大量的管线,如燃气管道、网络通讯线路、电力线路等,由于地下环境复杂多变,存在着气体泄漏、爆炸、火灾等安全风险。针对这些问题,提出一种基于窄带物联网技术(Narrow Band Internet of Things,NB-IoT)的地下管廊环境监测系统。该系统采用先进的传感器技术、NB-IoT技术、软件技术,系统主要分为数据采集模块、物联网云平台、远程监测系统三部分。数据采集模块以STM32作为主控单元连接各个传感器,采集温度、湿度、水位、可燃气体等数据,经过处理后利用NB-IoT网络上传到物联网云平台,远程监测系统调用物联网云平台的数据接口进行远程显示与预警。实验结果表明,系统在降低系统总体功耗的同时,能够实时、稳定地进行地下管廊环境监测,提前预防可能存在的风险。A large number of pipelines,such as gas pipelines,network communication lines,power lines,etc.,are laid out in urban underground pipeline corridors.Due to the complex and ever-changing underground environment,there are safety risks such as gas leakage,explosion,and fire.To address these issues,a narrowband Internet of Things(NB-IoT)based underground pipeline corridor environmental monitoring system is proposed.The system adopts advanced sensor technology,NB-IoT technology,and software technology.The system is mainly divided into three parts:data acquisition module,IoT cloud platform,and remote monitoring system.The data collection module uses STM32 as the main control unit to connect various sensors,collect temperature,humidity,water level,combustible gas and other data.After processing,it is uploaded to the IoT cloud platform using the NB-IoT network.The remote monitoring system calls the data interface of the IoT cloud platform for remote display and warning.The experimental results show that the system can reduce the overall power consumption of the system while monitoring the underground pipeline corridor environment in real-time and stably,preventing potential risks in advance.
