Abstract
The invention provides a walkie-talkie remote communication framework which comprises at least a pair of talking device, an address analysis service device. The communication between the talking device and the address analysis is transmitted by the INTERNET (WAN), and after the boot, the talking device regularly reports to the address analysis service device. When an active calling talking device needs the call, first, the active calling talking device refers to the address analysis service device for the address of a passive calling talking device and then uses the address to call the passive calling talking device which receives the call of the active calling talking device, and then both of the active calling talking device and the passive calling talking device enter a two-way audio and video talking. The walkie-talkie remote communication framework of the invention transmits voice and image on the basis of the existing ETHERNET, solves the problem that the traditional talking equipment is restricted by transmission distance, and realizes the function of audio and video talking in the LAN and that in the WAN.
Description
[technical field]
The present invention relates to the intercom technology, particularly relates to a kind of framework that can realize the intercom strange land intercommunication of two-way audio frequency and video intercommunication in the strange land.
[background technology]
Emulation bus is adopted in the most of employing of wiring bus mode in the building talkback, so transfer of data at present, audio transmission, video transmission, and this all causes almost not having compatibility and interoperability between each producer.In addition, adopt bus mode to transmit, also needing to solve has following problem: the 1) problem of limited transmission distance.As everyone knows, signal strength signal intensity increases with transmission range and decays, and therefore need amplify and conditioning signal intensity by increasing extras, but still can not solve transmission range completely.2) anti-interference problem comprises that data, Voice ﹠ Video are anti-interference.Comprise noise jamming and disturb, environmental interference etc. can be passed through differential transfer, increase shielding, increase live width, two-wire system/three-wire system transmission, but still can't thoroughly solve anti-interference problem.3) audio frequency and video the line is busy problem.Adopt traditional intercommunication of emulation bus mode, usually, simultaneously can only the transmission of one line audio frequency and video on the bus, can't transmit the multipath concurrence audio frequency and video, this causes system bus ground audio frequency and video, and usually the line is busy.Can improve by the method that increases bus etc., but these all are the methods of curing the symptoms, not the disease.Eventually the above, traditional intercommunication exists the disadvantage of wiring trouble, transmission range weak point, poor anti jamming capability, compatibility and interoperability difference.
[summary of the invention]
The object of the present invention is to provide a kind of framework that can realize the intercom strange land intercommunication of two-way audio frequency and video intercommunication in the strange land.
For achieving the above object, the invention provides the framework of a kind of intercom strange land intercommunication, comprise the talk back equipment of at least one pair of, an address resolution service equipment, wide area network is adopted in communication between talk back equipment and the address resolution service equipment, regularly report for work to the address resolution service equipment in talk back equipment start back, when the master exhales talk back equipment to call out, at first exhaled the address of talk back equipment to the inquiry of address resolution service equipment, utilize this address call to be exhaled equipment then, the equipment of being exhaled is accepted main calling of exhaling talk back equipment, and both sides enter two-way audio frequency and video intercommunication.
The advantage of the framework of intercom of the present invention strange land intercommunication is: utilize wide area network to carry out voice and image transmission, be not subjected to the restriction of traditional talk back equipment distance, and can carry out the two-way intercommunication of voice and video.

[embodiment]
The framework of intercom of the present invention strange land intercommunication by at least one pair of intercommunication establish put forth energy, an address resolution service equipment forms, the communication between talk back equipment and the address resolution service equipment utilizes wide area network, carries out the transmission of voice and image.Adopt this framework realization intercom strange land intercommunication to use and comprise digital audio/video transmission technology device address analytic technique etc.G.722 talk back equipment digitlization audio frequency and video transmission use, H.263 with RTP international standard technology, the address resolution service equipment adopts the DDNS technology.
See also Fig. 1 and Fig. 2, for the framework of intercom of the present invention strange land intercommunication comprises an intercommunication device A, an intercommunication equipment B, and an address resolution service equipment, the communication of talk back equipment A and talk back equipment B and address resolution service equipment utilizes Wide Area Network.
Using this framework to realize that the process of intercom strange land intercommunication is as described below: regularly reports for work to the address resolution service equipment in talk back equipment start back, when the master exhales talk back equipment A to need the calling talkback equipment B, at first inquire about the address of being exhaled talk back equipment B to the address resolution service equipment, thereafter the address resolution service equipment is replied the address information of talk back equipment B to talk back equipment A, notify talk back equipment B also calling talkback device A simultaneously, talk back equipment B replys to the address resolution service equipment then, talk back equipment A utilizes the address call of talk back equipment B to be exhaled talk back equipment B then, exhaled talk back equipment B to accept main calling of exhaling talk back equipment A, while talk back equipment B calling talkback device A, talk back equipment A replys the calling of talk back equipment B, both sides enter two-way audio frequency and video communication (RTP), under the situation of the narrow bandwidth of wide area network, also can only carry out the audio frequency intercommunication.
See also Fig. 3, be the composition logic diagram of the framework of this intercom strange land intercommunication.Wherein composition structure in the inside of talk back equipment A and talk back equipment B is identical, all adopting current version is the talk back equipment of AH8-H9VAC-7, the address resolution service equipment comprises DDNS (dynamic territory analyzing) database that connects in regular turn, the DDNS logic module, and network communication module, the address resolution service equipment is by the communication of network communication module realization with talk back equipment A and talk back equipment B, talk back equipment is after the room number address at talk back equipment B place is exhaled in the inquiry of address resolution service equipment, and IP address and port numbers that the address resolution service equipment can be replied this room number arrive talk back equipment B.See also Fig. 4, be the circuit connection diagram of the echo cancellation parts FM1073 that all uses in the talk back equipment.
The advantage of the framework of intercom remote intercommunication of the present invention is: the ICP/IP protocol that 1) adopts standard Network technology solves the problem of the compatible and interconnectivity difference of traditional intercom system. 2) based on existing The ETHENET network carries out voice and image transmitting, has solved traditional talk back equipment and limited by transmission range Problem. 3) adopt digitized transmission technology, solved that the audio frequency and video of traditional intercommunication easily are disturbed Problem. 4) adopt digitized transmission technology, solve traditional intercommunication the line is busy problem, realize really meaning " in every family logical " on the justice. 5) adopt NAT, the technology such as RTP/RTCP not only realize in the LAN The audio frequency and video intercommunication function has also been realized the audio frequency and video intercommunication function on the wide area network.
