当前由于对电力管廊内部状态缺乏智能、有效、可靠、经济的监测手段,电网输配电及电力安全运行存在隐患。窄带物联网(Narrow Band Internet of Things,NB-IoT)作为低功耗广域网通信技术,其具有覆盖广、支撑连接数量多、更低功耗、更低成本等特点,适宜覆盖面广、监测难度大的电力管廊的监测。文章基于NB-IoT技术构建电力管廊智能监测系统,系统由感知层、网络层和应用层组成。采用低功耗主控制器和NB通信模块,实现电力管廊中各种环境参数的有效监测。同时,实时传输到远程云平台,实现实时远程在线自动采集与数据存储。通过系统应用,验证了本设计有效可行,为电力管廊的监控、管理及维护提供了一种有效的监测手段。
Nowdays, due to the lack of intelligent, effective, reliable and economical monitoring means for the internal state of the power pipeline corridor, there are hidden dangers in the power transmission and distribution network and the safe operation. As a low power wide area network (LPWAN) communication technology, NB-IoT is characterized by wide coverage, large number of connections, lower power consumption and lower cost. It is suitable for power pipeline corridor monitoring with wide coverage and great difficulty. Based on NB-IoT, this paper designs an intelligent monitoring system of power pipeline corridor, which is composed of sense layer, network layer and application layer. Low-power main controller and NB communication module are used to realize effective monitoring of various environmental parameters in the power pipeline corridor. And collected data is transmitted to the remote cloud platform in real time, which enables real-time remote online automatic collection and data storage. Through the application of the system, the design is proved to be effective and feasible, which provides an effective monitoring means for the monitoring, management and maintenance of the power pipeline corridor.
