Converged Communication: A Communication Method in the Digital Era

Features

■     System Composition

The system consists of servers, dispatch consoles, general and intrinsic safety digital dispatch machines, ground output intrinsic safety telephone couplers, mining intrinsic safety telephones, cables, and other necessary equipment and system software.

 ■   Dispatch and command

The scheduling system integrates various functional modules and incorporates them into the entire integrated scheduling communication system, achieving digital integration of work, office, and emergency communication, and meeting the requirements of integrated scheduling communication in different scenarios.

■   Gas monitoring

Including toxic gases and explosive gases such as gas, gas monitoring sensors are installed in the relevant areas underground, which can real-time transmit the underground gas environment back to the platform safety control system and automatically generate alarm reminders.

■   Temperature monitoring

Real time temperature monitoring and hazard level definition of important locations such as coal mine passages and temperature measurement points, to prevent fire, high temperature and other dangerous situations, achieve early warning, alarm and automatic generation of alarm reminders.

■   Emergency broadcasting

When there is an emergency broadcast request, the system immediately switches to the emergency broadcast state, broadcasts urgently to the area that needs to be broadcasted, and at the same time, the system activates the alarm linkage function.

■    Video surveillance

Real time push monitoring images, GPS positioning video monitoring tracks real-time images of object movement, alarm terminals and video monitoring are linked to the wall and integrated into integrated scheduling communication to achieve linkage.   

■   Pull away transmission

It can achieve long-distance extension of extension users, with a maximum transmission distance of up to 10Km, making it more convenient for both in and out of the well, administrative and scheduling networking.

■   Dual circuit protection

The underground extension can achieve dual circuit protection for communication channels. Each extension user has two communication channels, the main shaft and the auxiliary shaft. In case of any open circuit or short circuit fault in either line, the host can ensure the normal operation of the extension communication and report the corresponding line fault.
