Communication system of intrinsic safety high-speed integrated channel for a mine

Abstract

The invention discloses a communication system of an intrinsic safety high-speed integrated channel for a mine, which is mainly used for the real-time underground and ground information exchange of a coal mine. The communication system comprises a channel ground optical transmitter and receiver and an underground optical transmitter and receiver, wherein the channel ground optical transmitter and receiver respectively comprises a transmitter and a receiver; the transmitter comprises a signal input unit, a signal output processing unit, a signal multiplexing unit, a string absorbing data interface circuit and an optical fiber receiving and transmitting module which are sequentially connected; the receiver comprises a optical fiber receiving and transmitting module, a series-to-parallel data interface circuit, a signal shunting unit, a signal receiving and processing unit and a signal output unit which are sequentially connected; and optical fiber transmission is realized through the optical fiber receiving and transmitting module between the transmitter and the receiver. The invention has the advantages of low transmission cost, high communication efficiency, simultaneously integrated transmission of the video, voice and data information of the coal mine, information sharing, high system reliability, good openness and high interference resisting capacity.

Description

technical field [0001] The invention relates to a communication system, in particular to a communication system of an intrinsically safe mine-used high-speed integrated channel. Background technique [0002] Coal is currently one of the most important energy sources available to human beings, and is related to the healthy development of the entire society. Coal mine safety and high-efficiency production have undoubtedly become a hot spot of social concern. It not only affects the social economy, but also concerns the life safety of mining personnel. At present, the country has attached great importance to the safety of coal mining, and it is mandatory for all coal mine production enterprises to have a safety inspection system. The environment in coal mines is very complex and harsh, and there are many objects that need to be controlled and monitored. At present, the coal mine information system mainly consists of three parts: ① Important coal mine equipment and related mea...
