Problems solved by technology

[0002] The currently known leakage communication technology can realize voice communication in mines, but because it is analog communication, the effect is poor, the function is single, full-duplex communication is not possible, and the installation and debugging are complicated
Known underground PHS, because group call cannot be realized, there is no scheduling function

Embodiment Construction

[0012] Accompanying drawing has provided the structural principle block diagram of the present invention. The system consists of two major components: a wired backbone network and a wireless network:

[0013] (1) The wired backbone network is composed of WEB (network) server, SIP (voice) server, streaming media server, router, and explosion-proof network switch. The WEB server, SIP server, and streaming media server are connected to the router through flame-retardant optical cables and placed on the well. An explosion-proof network switch is placed every 3 kilometers underground. The first explosion-proof network switch underground is connected to the router above the well through flame-retardant optical cables, and the explosion-proof network switches underground are interconnected through flame-retardant optical cables.

[0014] (2) The wireless network consists of an explosion-proof wireless network access point (AP) and an explosion-proof wireless terminal. The explosion...

Abstract

The system includes two part: the wired backbone network composed of network WEB server, voice SIP server, stream media server, router and explosion proof network exchanger, and the wireless network composed of access point of explosion proof network and explosion proof type wireless terminals. WEB server, SIP server and stream media server placed above well are connected to the router. One explosion proof network exchanger is placed underside of well at each certain distance. Each exchanger is linked each other. One of the exchangers is connected to the router above well. The access point of explosion proof network is connected to the explosion proof network exchanger. Through wireless network protocol, the explosion proof type wireless terminals are connected to the access point of explosion proof network. The invention can implement functions of voice communication, scheduling, positioning, video monitoring and data transmission between above well and underside of well.

Description

technical field [0001] The invention relates to underground communication equipment in coal mines, belonging to the technical field of network communication. Background technique [0002] The current known leakage communication technology can realize voice communication under the mine, but because it is an analog communication, the effect is poor, the function is single, full-duplex communication is not possible, and the installation and debugging are complicated. Known downhole PHS, owing to can't realize group call, has no scheduling function. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a computer network-based mine voice communication system, which can realize the functions of mine mobile voice communication, scheduling, and positioning, and can be extended to video monitoring, telemetry and remote control data transmission. It can also be connected to the Internet to realize remote communication. [0...
