Wireless relay explosion-proof communication system for gas tunnel

Abstract

The invention discloses a wireless relay explosion-proof communication system for a gas tunnel. The wireless relay explosion-proof communication system comprises a main station and an intelligent terminal which are arranged outside the gas tunnel, and an intrinsic safety type terminal and a plurality of relay units which are arranged in the gas tunnel, wherein the plurality of relay units are arranged at intervals along the gas tunnel section by section and are in communication connection with one another, the main station is in communication connection with the relay units, a communication network is constructed in the gas tunnel through the plurality of relay units, The intelligent terminal is in communication connection with the master station and enters a to-be-matched state; the intrinsic safety type terminal is in communication connection with any relay unit and is correspondingly matched and connected with the intelligent terminal through the main station, and the intrinsic safety type terminal is configured to perform remote control operation on the intelligent terminal after being in communication connection with the intelligent terminal, send communication information to the intelligent terminal and receive the communication information sent by the intelligent terminal. According to the wireless relay explosion-proof communication system, construction safety in the gas tunnel can be guaranteed, data communication precision and communication efficiency in the gas tunnel are improved, and the risk of privacy disclosure is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of mobile communication in an inflammable and explosive environment, in particular to a wireless relay explosion-proof communication system for a gas tunnel. Background technique [0002] In coal mine collection operations, workers often need to carry out construction work inside the mine. Due to the complex terrain environment, serious electromagnetic interference during construction operations, and flammable and explosive gases in the internal environment of the mine, the staff inside the mine External information exchange is difficult. In order to solve the above problems, a variety of intrinsically safe explosion-proof mobile phones have been developed in the prior art. By increasing the protection circuit, increasing the line interval of the circuit board, shielding and packaging electronic components, and using special materials to manufacture mobile phone casings, etc. And other measures to ensure th...

However, in this case, in order to avoid affecting the timeliness of message reception, the staff need to take out the mobile phone card in their own mobile phone and replace it with the mining mobile phone. The operation of replacing the mobile phone terminal not only loses all kinds of Information, such as address book, chat records, call records, etc., and privacy risk is precisely one of the biggest risks facing social groups today. The information is difficult to accept. Even though the functions of mining mobile phones are becoming more and more perfect, and various practical functions are attached to them based on the specific use environment, people still have great rejection and resistance to them.
