The ultralong-distance intercom has the advantages of ingenious structure and convenient use, and can effectively solve the problem of narrow application coverage area since the digital cluster intercom can only use the CDMA1x network or the Evdo network.
Description
Technical field
The utility model relates to wireless overlength distance intercommunication communication, particularly a kind of overlength distance intercom.
Background technology
Traditional analog wireless tranceiver communication distance is too near.Existing Digital Clustering intercommunication (VOIP communication), be in fact using speech as a kind of application of playing the line data, but can only provide cluster intercommunication communication by the CDMA1X packet domain; Point-to-point, point-to-multipoint half-duplex operation service are provided, and its shortcoming is: communication network is used single, can only use CDMA1x network or Evdo network.
Summary of the invention
For above-mentioned situation, for overcoming the defect of prior art, the purpose of the utility model just is to provide a kind of overlength distance intercom, can effectively solve the Digital Clustering intercom and can only use CDMA1x network or Evdo network to cause the problem of using the coverage area narrow.
The technical scheme of its solution is, comprise housing and control circuit, control circuit is housed in housing, control circuit comprises wireless data transceiving radio road and central processor CPU, central processor CPU is connected with wireless data transceiving radio road, central processor CPU and GPS navigation system, the compress speech circuit is connected with the voice restoration circuit, the compress speech circuit is connected with front end voice collecting circuit, on the voice collecting circuit, talking handle is housed, the voice restoration circuit is connected with the voice broadcast circuit, the voice broadcast circuit is connected with the loudspeaker of housing front end, central processor CPU is connected with the display on housing.
The utility model structure is ingenious, and manufacturing process is simple, easy to use, can effectively solve the Digital Clustering intercom and can only use CDMA1x network or Evdo network and the narrow problem of use coverage area.
The accompanying drawing explanation
Fig. 1 is the utility model principle schematic.
Fig. 2 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further details.
By Fig. 1, Fig. 2 provides, the utility model comprises housing and control circuit, in housing 1, control circuit is housed, control circuit comprises wireless data transceiving radio road 2 and central processor CPU 3, central processor CPU 3 is connected with wireless data transceiving radio road 2, central processor CPU 3 and GPS navigation system 4, compress speech circuit 5 is connected with voice restoration circuit 6, compress speech circuit 5 is connected with front end voice collecting circuit 7, talking handle 8 is housed on voice collecting circuit 7, voice restoration circuit 6 is connected with voice broadcast circuit 9, voice broadcast circuit 9 is connected with the loudspeaker 10 of housing 1 front end, central processor CPU 3 is connected with the display 11 on housing 1.
In order to guarantee result of use, said wireless data transceiving radio road 2 provided with SIM card therein, wireless data transceiving radio road 2 is through SIM card and existing communication base station wireless connections.
Said housing front end has a plurality of control buttons 12 that are connected with central processor CPU 3, regulates control button 12, can show through display the information of vehicle, such as: time, the speed of a motor vehicle, direction, the number-plate number that makes a call etc.
Operation principle of the present utility model is:
(1) intercommunication function operation principle
Front end voice collecting circuit 7 is delivered to compress speech circuit 5 to what gather to voice, and compression, encryption, packing by compress speech circuit 5 are processed into packet.Then the packet of encrypting is delivered to central processor CPU 3, the packet of encrypting arrives the SIM card in wireless data transceiving radio road 2 after central processor CPU 3 is processed.SIM card in wireless data transceiving radio road 2 arrives the machine room server to data packet transmission by wireless public network and the Internet.After the machine room server is received data, analyze the Data Source terminal, then judge the other terminal that data distributing arrives, then to qualified remote terminal, by the Internet and wireless public network, carry out the transmission of packet.Terminal can be collected packet by the SIM card in wireless data transceiving radio road 2, packet is after central processor CPU 3 is processed, again packet is delivered to also primary circuit 6 of speech data, packet is reduced into to sound and the loudspeaker 10 by voice broadcast circuit 9 play back, thereby the people hears sound.
(2) GPS location operation principle
GPS navigation system 4 becomes data 1 to driver's particular location measurement, and data 1 are transported to central processor CPU 3.SIM card in wireless data transceiving radio road 2 becomes driver's particular location measurement data 2 bags to be transferred to the machine room server by wireless public network with the Internet.After the machine room server is received data 2, then data 2 are transported to central processor CPU 3, obtain a result after central processor CPU 3 deal with data 1 and data 2, result is delivered on display 11, can realize the speed of a motor vehicle, the demonstration of direction.
The utility model has the advantages that: can realize the intercommunication of the overlength distance communications field.
The scope of application of the present utility model is: public security department, communications and transportation, city management, the conversational communications such as large-scale activity and race and railway dispatching.
The utility model structure is ingenious, and manufacturing process is simple, easy to use, can effectively solve the Digital Clustering intercom and can only use CDMA1x network or Evdo network and the narrow problem of use coverage area.
