Problems solved by technology

[0003] At present, coal mine underground broadcasting technologies include common cable FM broadcasting, CAN bus mode, constant voltage broadcasting mode, etc. All these technologies need to form an independent network, with short transmission distance and poor anti-interference ability
The integration of the above systems is poor. In terms of appearance, most of the equipment adopts flameproof and intrinsically safe type, which is bulky and heavy, which brings great inconvenience to production, installation and maintenance. Equipment management is inconvenient. It also consumes a lot of money
In terms of performance, the power amplifier of the broadcasting system is single and cannot be integrated into the dispatching system

Embodiment Construction

[0067] In order to make the technical solutions and advantages of the present invention clearer, the implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0068] figure 1 It shows a schematic structural diagram of a mine broadcasting system proposed by an embodiment of the present invention, such as figure 1 As shown, the system includes: a surface component and a downhole component.

[0069] It should be noted that, since the mine broadcasting system proposed in this embodiment is applied in a mine, the ground components are components installed outside the mine, and the underground components are components installed in the mine. Specifically, as figure 1 As shown, the ground component includes a dispatching computer, an Ethernet switch, and a broadcast server; the downhole component includes a broadcast terminal, wherein the dispatching computer and the broadcast server are respectively co...

Abstract

The invention discloses a mine broadcasting system. The mine broadcasting system comprises a ground assembly and a downhole assembly, wherein the ground assembly comprises a scheduling computer, an Ethernet switch and a broadcast server; the downhole assembly comprises a broadcast terminal; and the scheduling computer and the broadcast server are respectively in communication connection with a broadcast terminal through the Ethernet switch. According to the mine broadcasting system, the mine communication contact level and the communication efficiency are improved, service power amplificationof voice, multimedia scheduling, cluster intercom, broadcast scheduling and the like are realized, the working efficiency and management and informatization level of a mine are greatly improved, greateconomic and social benefits are generated, and the mine broadcasting system has the advantages of simple structure, easy networking, strong anti-interference capability, high transmission rate and the like; and the overall construction, wiring and material cost can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of communication equipment. More specifically, it relates to a mine broadcasting system and using method. Background technique [0002] Due to the special geographical environment of the mine, the mine broadcasting system plays an important role in the coal mine. It can not only play music, notifications, paging broadcasts and publicity, but also send evacuation warnings in emergency situations. It is a very critical information dissemination platform. [0003] At present, underground broadcasting technologies in coal mines include common-cable FM broadcasting, CAN bus mode, and constant-voltage broadcasting mode. The integration of the above systems is poor. In terms of appearance, most of the equipment adopts flameproof and intrinsically safe type, which is bulky and heavy, which brings great inconvenience to production, installation and maintenance. Equipment management is inconvenient. It also consume...
