Tunnel communication device

Abstract

A tunnel communication device relates to a communication device, in particular to a mine communication device, which comprises an interphone inside a tunnel, an interphone outside the tunnel, a relaystation, a communication cable, an optical fiber, a feed pipe, an optical fiber transmission machine and a radio frequency amplifier; the problem that no interphone signal exists in a tunnel, a concrete room and other areas is solved, the personal safety of staff is guaranteed to a certain extent, and a corresponding positive effect is achieved on equipment monitoring.

Description

technical field [0001] The invention relates to a communication device, especially a mine communication device. Background technique [0002] Nowadays, many mine workshops involve many tunnels and concrete rooms, which cannot be covered by walkie-talkie signals. When the staff is carrying out production operations in the above-mentioned areas, the mobile phone signal cannot be received. The walkie-talkie used in the workshop only relies on the power of the walkie-talkie itself to transmit and receive, and cannot send and receive information. As a result, real-time communication inside and outside the tunnel cannot be performed, and the central control operation instructions cannot be received. The area listens to the instructions issued by the central control or reports the operation status of the equipment. There is a period of time interval during this period, which can easily cause safety accidents caused by untimely work communication, and there are major safety hazard...
