System Overview

The mine video broadcast communication system uses TCP/IP and new bus as communication protocols. It can be used as an important part of the coal mine safety system and provide an effective communication method for coal mine safety production. The new mine broadcast communication system can be distributed in tunnels, waiting rooms, along the monkey car line, along the belt line, coal mining face, excavation face and other positions to completely eliminate call blind spots. The underground workers and resting personnel can clearly hear the speaker broadcast sound and alarm voice and can communicate with the well and underground through the intercom speaker, and transmit the image data of each monitoring point to the central monitoring room, so as to realize the monitoring and real-time communication of the underground workers and ensure the safety of the personnel.

COME-STAR Solution

System requirement:

1) The underground working area has a harsh environment, and the equipment needs to operate stably and reliably

2) The underground equipment needs to have explosion-proof safety features, low power consumption, and meet the requirements of the flammable and explosive environment underground

3) A reliable 10G redundant ring network that can be quickly restored when a fault occurs

4) Sufficient bandwidth to meet the requirements of video and voice data transmission

5) Convenient network management and diagnostic functions

6) There are a variety of terminal devices, and a variety of port access methods need to be provided, such as serial ports, CAN ports, etc.

Solution:

(A) Ground equipment

The ground equipment of the system consists of dispatching main and standby machines, voice gateways, IP phones, intercom microphones, storage servers, UPS power supplies, printers, sound and light alarms, three-layer 10G convergence switches, etc.

(B) Underground equipment

1) It is mainly composed of IP broadcasting, broadcast substations, monitoring substations, mining intrinsically safe Gigabit ring network switches, mining intrinsically safe 100M Ethernet switches, etc.;

2) The mine broadcast communication system can broadcast the emergency handling plan voice through the "mine voice broadcast system" according to the specific situation of the dispatching personnel;

3) The underground speakers will repeatedly play the alarm sound and alarm voice, promptly notify the underground workers to evacuate and leave quickly, and provide necessary information assistance for the safety measures and emergency rescue taken;

4) Try to avoid the occurrence of safety accidents and reduce the losses caused by safety accidents;

5) It can play propaganda and education, current news, background music and other content, which can play a positive role in enhancing the safety awareness of employees, entertaining the cultural life of employees, and realizing humanized management;

6) Monitor the operation of underground workers and ensure the real-time status of workers.
