The manhole cover anomaly monitor is an intelligent online monitoring device that senses the status of manhole covers. It is installed on the back of the manhole cover and monitors its status in real time. When the manhole cover tilts, shifts, overflows, or other abnormalities occur, it immediately triggers an alarm and sends the alarm information to the monitoring center.
