By mutual connection of the various components in the system, safe production commands, daily broadcasts of files and safety knowledge and two-way intercommunication between ground working personnel and underground working personnel can be realized, and local music and certain video files can be further played. The system has advantages of strong anti-interference capability, high output sound quality, wide coverage of voice signals, safe and reliable performance, and the like.
Description
Technical field
The utility model relates to a kind of mining broadcasting intercom system, and this system is mainly used in operations such as operating personnel's under factory site, ore deposit face and the mine safety commander, two-way intercommunication, scheduling, belongs to communication technical field.
Background technology
Coal mine since in depth down and passage crisscross; And have an inflammable and explosive methane gas etc., therefore in this special geological environment, need to use special-purpose and broadcasting intercom system that have higher reliability keeps communicating by letter with the personnel of underground work.
The system that present industry inside, colliery is used to communicate by letter mainly contains two kinds: a kind of is dispatcher telephone system, and a kind of in addition is the Personal Handyphone System system.But this two cover system all is main purpose with the one-way traffic to be designed; Can not realize the two-way intercommunication under ground and the mine, when emergency occurring, for example gas leakage appears in the down-hole or other accidents need notify underground operators to withdraw; Command function when this two cover system all lacks emergency escape; Particularly because subsurface environment seals very much, whether normally the personnel in the pit can not clearly know reservation route passing through of safety when withdrawing, if can not withdraw according to original route; Whether also have new route can in time instruct the operating worker escape, this has great influence to the rescue miner when having an accident.If when control centre and mine distance is far away, the device distance between the system also can be far away, causes the antijamming capability of these two kinds of telephone systems weak, exports that psycho-acoustical quality is not high, the voice signal coverage rate can not well not guarantee the fail safe under the mine entirely.
To the deficiency of above-mentioned existence, be badly in need of a kind of safety commander that can operate in the face of underground operators of research and development with realizing, can realize the communication system of the two-way intercommunication under ground and the mine again.
The utility model content
To the problem that occurs in the above-mentioned technology; The utility model provides a kind of mining broadcasting intercom system; The daily broadcasting of safe commander, file and security knowledge that this system can realize through connecting each other of each parts producing; Two-way intercommunication under ground and the mine can also be play simultaneously local music and looked the screen file with some, and this system has that antijamming capability is strong, output tonequality height, voice signal broad covered area, advantage such as safe and reliable.
In order to reach the foregoing invention purpose; The technical scheme that the utility model adopts is; A kind of mining broadcasting intercom system is provided, comprises computer, broadcasting main website, first transducer, second transducer, first ring exchanger, second ring exchanger and some hands free telephones; Said broadcasting main website is connected with first transducer with computer respectively; Said first transducer is connected with first ring exchanger, and first ring exchanger is connected through optical cable with second ring exchanger; Said second ring exchanger is connected through cable with second transducer; Said second transducer is connected with some hands free telephones through cable; Said first transducer, second transducer, first ring exchanger and second ring exchanger all dispose a mine explosion-suppression and intrinsic safety type D.C. regulated power supply.
Preferably, said computer, broadcasting main website, first transducer and the first ring exchanger setting are on the ground; Said second transducer, second ring exchanger and some hands free telephones are arranged in the mine.
With respect to prior art, the utlity model has following beneficial effect:
1, has multiple communication function; Broadcasting main website, ring exchanger, transducer and hands free telephone through expansion combines and makes this broadcasting intercom system can ensure the arbitrfary point point to-point communication of ground and down-hole when the normal operation; Can also realize the function of two-way intercommunication; When safe condition occurring under the mine and go wrong, the downhole operations personnel can get in touch with the terrestrial broadcasting station timely, improved in the mine fail safe.
2, adopt optical cable to connect between two of the utility model ring exchangers; Connect through cable between all the other each devices; Help improving traffic rate and stability; And adopt cascade system between the transmission range equipment far away, can guarantee this system's antijamming capability, output tonequality, voice signal coverage rate effectively.
Description of drawings
Fig. 1 is the theory diagram of mining broadcasting intercom system.
Embodiment
The utility model is done bright specifically below in conjunction with accompanying drawing:
As shown in the figure, broadcasting intercom system that this is mining comprises computer, broadcasting main website, first transducer, second transducer, first ring exchanger, second ring exchanger and some hands free telephones; Said broadcasting main website is connected with first transducer with computer respectively; Said first transducer is connected with first ring exchanger, and first ring exchanger is connected through optical cable with second ring exchanger; Said second ring exchanger is connected through cable with second transducer; Said second transducer is connected with some hands free telephones through cable; Said first transducer, second transducer, first ring exchanger and second ring exchanger all dispose a mine explosion-suppression and intrinsic safety type D.C. regulated power supply; Said computer, broadcasting main website, first transducer and the first ring exchanger setting are on the ground; Said second transducer, second ring exchanger and some hands free telephones are arranged in the mine.
At first will broadcast main website, first transducer, second transducer, first ring exchanger, second ring exchanger and some hands free telephones and connect and compose broadcasting intercom system through cable; Wherein connect through optical cable between first ring exchanger, second ring exchanger; The management software of broadcasting intercom system then is installed on computers; Software is opened software setting after installing successfully; Software setting success back search broadcasting intercommunication sub-station equipment, the user can define in the list of devices that search comes out equipment voluntarily or the equipment group name is claimed; The user can also according to circumstances select the sound source input mode of uphole equipment, and this software is supported microphone, MP3 or outside three kinds of sound sources.Administrative staff can call out or monitor an equipment; Can carry out two-way intercommunication with an equipment, can carry out multicast, can broadcast the intercommunication substation to all and broadcast a group equipment; Last calling device can be replied, and top all operations can be stopped at any time.This software can be next to mine, the music of a group or all devices is controlled; Support functions such as program request and loop play; Edit play content and play rules on the support software backstage; The manager can be under the mine during operating personnel's rest, and playing back music lets suitable the loosening of operating personnel.
