基于LoRa技术的地下电缆运行环境监测系统设计

Design of Environmental Monitoring System for Underground Cable Operation Based on LoRa Technology

针对目前城市中地下电缆由施工引起的外力破坏事故频发的情况,提出了基于LoRa技术的地下电缆运行环境监测系统。该系统通过布置一定数量的数据采集设备对处于危险地段的地下电缆所处环境的温湿度、烟雾、振动等物理量进行实时采集,在异常情况下能就地报警,并实时将数据通过LoRa网络上传至汇集端。该系统具有布置灵活、运行周期长、实用性强等优点,能远距离感知电缆运行环境状态,对电缆的安全维护管理具有积极意义。

In view of the frequent occurrence of external force damage accidents caused by construction of underground cables in cities at present,an environmental monitoring system for underground cables operation based on LoRa technology is proposed.The system collects real-time physical quantities such as temperature,humidity,smoke,and vibration in the environment of underground cables in dangerous areas by arranging a certain number of data acquisition equipment,and can alarm on the spot under abnormal conditions,and upload the data to the collection end in real time through LoRa network.The system has the advantages of flexible layout,long operation cycle and strong practicability.It can sense the state of cable operation environment from a long distance,and has positive significance for cable safety maintenance and management.
