摘　　要：一种高压电缆接地电流在线监测系统,在前端研制集感应取电、数据采集、信号发射为一体的监测装置,采用Lora+5G无线传输策略,在隧道密闭空间内应用低功耗的Lora通信方式,将前端采集的数据传至部署在隧道边界的汇聚节点,再通过5G通信技术将汇聚后的数据统一传至后台服务器。经过现场试验,监测装置能在电缆隧道、工井等复杂环境运行,数据传输距离、采集率能够满足现场需求。This paper describes an online monitoring system for high-voltage cable grounding current,and develops a monitoring device integrating induction power acquisition,data acquisition and signal transmission at the front end,adopts the Lora+5G wireless transmission strategy,applies the low-power Lora communication mode in the confined space of the tunnel,transmits the data collected at the front end to the convergence node deployed at the tunnel boundary,and then transmits the converged data to the background server through 5G communication technology.After field tests,the monitoring device can operate in complex environments such as cable tunnels and wells,and the data transmission distance and collection rate can meet the needs of the site.
