Integrated Communication Solution for Tunnel Construction

During tunnel excavation, it is necessary to deploy telephone, voice intercom, and voice broadcast stations along the route. At this point, the range of radio intercom is greatly limited, and if used, more relay stations must be deployed along the route.

Generally, video surveillance, stress detection, ventilation control, and lighting control along the route can also be integrated into the same communication system (though in practical applications, these communication systems often use a separate set of communication equipment, typically employing dual-optical-port media converters, serial servers, and PoE power supply.

IDM POE-M08+ = 3 units of Gigabit media converters + 3 Gigabit port 8 Fast Ethernet port switches + 4-port serial server + 150W 8-port PoE power supply).
