蒙自DG-SMCM-T30-RP Smart Manhole Cover Monitoring Terminal

The smart manhole cover monitoring terminal can be easily installed at the base of the manhole cover, transforming a conventional cover into an intelligent one. It enables unified management and real-time monitoring of the cover’s basic information, facility status, and conditions such as water inundation or submersion. In the event of anomalies—such as the cover being opened, lost, or sewage overflowing—the system automatically triggers an alarm to the supervisory center, effectively supporting intelligent oversight of urban lifelines.

Product Description

Measurement principle

The smart manhole cover monitoring terminal can be easily installed at the base of a manhole cover, transforming an ordinary cover into a smart one. It enables unified management and real-time monitoring of the cover’s basic information, facility status, and conditions such as water inundation or submersion. When anomalies occur—such as the cover being opened, lost, or sewage overflowing—the system automatically triggers an alarm at the supervisory center, effectively supporting intelligent oversight of urban lifelines.
