Abstract

The invention discloses a multimedia terminal of a mining communication control system and the mining communication control system. The multimedia terminal has the functions of audio and video conversation, network data exchange, CAN / 485 intrinsic / non-intrinsic conversion and the like. The multimedia terminal comprises an intrinsic safety box body and an explosion-proof box body, a power supply module, a signal isolation conversion module and an SIP conversation module are arranged in the explosion-proof box body. The power supply module is used for supplying power to the signal isolation conversion module and the SIP conversation module. The signal isolation conversion module realizes bidirectional transparent transmission between a non-intrinsic CAN signal and an intrinsic safety CAN signal, bidirectional transparent transmission between a non-intrinsic 485 signal and an intrinsic safety 485 signal, and protocol conversion between the CAN signal and the 485 signal. The SIP conversation module realizes audio and video conversation and network data exchange.

Description

technical field [0001] The invention relates to the technical field of mine communication, in particular to a multimedia terminal of a mine communication control system and the mine communication control system. Background technique [0002] The multimedia terminal is an audio conversion device used in the coal mine communication control system, which realizes the conversion between digital audio and analog audio of the SIP protocol, and can realize functions such as video calls and calls. Through the multimedia terminal, the audio signals of KTC118, KTC2, and broadcasting can be intercommunicated, and the voice of the wireless communication system with underground WIFI standard and 3G standard can be realized, and the video call function can be supported. [0003] The inventor found in the research and development process that the existing multimedia terminals cannot meet the needs of viewing the actual on-site conditions of the two parties in the call in real time between ...
