Tunnel electronic manhole cover monitoring system

The intelligent manhole cover monitoring system uses the current advanced wireless communication technology, power supply technology, and sensor technology to incorporate the state of the manhole cover, the state of the underground environment, the opening of the manhole cover, and the inspection of the manhole cover into the unified maintenance management system, and establish the corresponding alarm processing Mechanism, the status of the manhole cover and the alarm content are displayed through the electronic map. If the manhole cover is stolen or damaged, the monitoring personnel can go to the scene to deal with it in time and quickly Resolve safety hazards. The system can realize the data collection, real-time display, diagnostic analysis, fault alarm of various security signals of the manhole cover, so that the dispatch center, operation and maintenance station, and management departments can intuitively understand and master the operation of the underground pipeline network
