Product Manual

Smart Manhole Cover Monitoring Terminal, Model AN-DMC

Product Introduction

The Smart Manhole Cover Monitoring Terminal (hereinafter referred to as 'the Terminal') is an independently developed low-power smart sensor device designed by our company specifically for smart cities, municipal pipe networks, underground utility tunnels and similar environments. Based on an internal multi-axis attitude sensor, high-precision environmental sensing matrix and ranging radar, paired with a high-speed 4G wireless communication module, it can guard the safety of underground facilities 24/7 with high reliability.

Installed on the inner side of the manhole cover, the Terminal requires no complex construction on the road surface, enabling rapid deployment and simple post-installation maintenance. It effectively reduces labor and time costs, providing an efficient and stable intelligent solution for municipal manhole cover safety management (anti-theft, anti-displacement, anti-fall, etc.).
