Description
Technical Field
The utility model relates to a communication device, especially mine communication device.
Background
Many mine workshops today involve many tunnels and concrete rooms, which are not covered by intercom signals. When the staff carries out production operation in the area, the mobile phone signals cannot be received. The interphone used in the workshop only transmits and receives by means of the power of the interphone and cannot transmit and receive information, so that real-time communication cannot be achieved inside and outside the tunnel, and the central control operation instruction cannot be received. A period of time interval exists during the period, so that safety accidents caused by untimely work communication are easily caused, and a great potential safety hazard exists.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a tunnel communication device has solved the problem that there is not intercom signal in areas such as tunnel, concrete room, has ensured staff personal safety to a certain extent, plays corresponding positive effect to the control of equipment.
In order to achieve the above purpose, the utility model provides a following technical scheme:
a tunnel communication device comprises an interphone 1 in a tunnel, an interphone 8 outside the tunnel, a relay station 7, a communication cable 3, an optical fiber 6, a feed tube 2, an optical fiber transmitter 5 and a radio frequency amplifier 4; the feed pipe 2 is laid in the tunnel and extends to the corner of the concrete chamber and the edge of the tunnel to collect analog signals sent by the interphone 1 in the tunnel; the relay station 7, the optical fiber transmitter 5 and the radio frequency amplifier 4 are located outside the tunnel, the feeder tube 2 transmits an analog signal to the radio frequency amplifier 4 through the communication cable 3, the radio frequency amplifier 4 transmits a signal to the optical fiber transmitter 5 through the communication cable 3, the optical fiber transmitter 5 has a function of converting the analog signal into a digital signal, and the optical fiber transmitter 5 is connected with the relay station 7 through an optical fiber 6; the relay station 7 decodes the digital signal into an analog signal and transmits the analog signal to the tunnel outer interphone 8 for receiving through radio waves, so that the tunnel inner interphone 1 and the tunnel outer interphone 8 can communicate with each other.
Further: the outside of the feed tube 2 is a copper tube.
Further: the optical fiber 6 is made of a rat-proof material.
Advantageous technical effects
The utility model is suitable for a digit, simulation, cluster intercom system extends basic station coverage, eliminates signal blind area, shadow district, improves server speech quality. And single-mode optical fiber transmission is adopted, so that the loss is low, the cost is low, and the construction is simple. The optical fiber between the near-end machine and the far-end machine can be pulled for 20-80 kilometers furthest, one multi-path near-end machine can be connected with N far-end machines at most, and a star networking mode with larger coverage range can be realized: the method is suitable for covering long and narrow tunnels or concrete chamber signals. The relay station applies a brand new RoIP technology, voice signals borne by Radio (Radio) signals of the traditional relay station are transmitted through an IP network, local talkback signal relay can be achieved, voice real-time performance and error-free transmission of PTT signals can be achieved through the IP network, different geographic spaces and different frequency bands can be easily met, network interconnection and voice sharing are achieved, one-key type conversation is achieved, the problem that transmission distance is limited by transmission environment, transmitting power, receiving sensitivity and the like in Radio transmission is solved, and the purpose of ultra-long distance relay-free network interconnection is achieved. Because the tunnel of workshop is long, and the concrete room is many, the utility model discloses intercom system has adopted the mode of wired introduction to acquire the signal source, and this kind of mode signal coverage mode scope is wide, and intercom receiving and dispatching audio frequency is effectual.

FIG. 1 is a connection diagram of the present invention.
In the figure, 1-interphone in tunnel, 2-feeder tube, 3-communication cable, 4-radio frequency amplifier, 5-optical fiber transmitter, 6-optical fiber, 7-relay station and 8-interphone outside tunnel.
Detailed Description
The invention will be further explained with reference to the drawings and practical application of production.
Example 1: as shown in fig. 1, a tunnel communication device includes an intercom 1 inside a tunnel, an intercom 8 outside the tunnel, a relay station 7, a communication cable 3, an optical fiber 6, a feeder tube 2, an optical fiber transmitter 5, and a radio frequency amplifier 4; the feed pipe 2 is laid in the tunnel and extends to the corner of the concrete chamber and the edge of the tunnel to collect analog signals sent by the interphone 1 in the tunnel; the relay station 7, the optical fiber transmitter 5 and the radio frequency amplifier 4 are located outside the tunnel, the feeder tube 2 transmits an analog signal to the radio frequency amplifier 4 through the communication cable 3, the radio frequency amplifier 4 transmits a signal to the optical fiber transmitter 5 through the communication cable 3, the optical fiber transmitter 5 has a function of converting the analog signal into a digital signal, and the optical fiber transmitter 5 is connected with the relay station 7 through an optical fiber 6; the relay station 7 decodes the digital signal into an analog signal and transmits the analog signal to the tunnel outer interphone 8 for receiving through radio waves, so that the tunnel inner interphone 1 and the tunnel outer interphone 8 can communicate with each other.
Example 2: example 1 the feed tube 2 is externally a copper tube.
Example 3: the optical fiber 6 of any one of embodiments 1 and 2 is made of a rat-proof material.
