路面积水带电实时在线监测系统设计

Design of Real-Time Online Monitoring System for Electrified Water-Logged Ground

基于现有的漏电检测仪和水浸检测仪等无法有效指示路面积水带电,设计了路面积水带电实时在线监测系统。通过安装于灯杆下部的1#电极和灯杆附近地面的2#电极,不间断监测路面积水带电情况。危险发生时,系统能及时发出声光告警信号,并通过物联网通讯技术将积水带电信息传送至远程监控中心,及时切断灯杆供电,消除安全隐患。该系统采用太阳能供电,超低功耗设计,监测采集系统和漏电回路光电隔离,提高了系统的安全性和可靠性。

This real-time on-line monitoring system is designed based on the fact that the existing leakage detector and water immersion detector can not effectively indicate the electrified water-logged ground. Two electrodes are installed where the first electrode is placed under the pole of light and the second one is installed on the ground near the pole of light. Then, the voltage of water-logged ground can be continuously monitored. When there are some dangers, the system can emit sound and light in time to warn the pedestrians to pay attention to safety. At the same time, the system can transmit the information to the remote monitoring center through the Interact of Things communication technology. Then, the remote monitoring center can cut off the power supply immediately to prevent potential safety hazards. The system is powered by solar energy and is designed with ultra-low power technology. Also, the monitoring acquisition system and leakage circuit are isolated by the optical components, which greatly improve the safety and reliability of the system.
