And a kind of ship-to-shore audio-video based on SIP dispatches system and the naval vessel equipped with the system.
Background technique
Ship at present, especially the public affair ship level of informatization are higher and higher, have realized point-to-point video conference between ship-to-shore, ship
Each system fortune of interior video monitoring, the passback of wireless individual image, cabin, the informationization for the systems such as driving, and the achievable ship in part
Row parameter synchronizes long-range monitoring bank base.Telecommunication management may be implemented in current each internal system, but each system is mutually dispersed, no
Between homologous ray lack " hinge " so that the audio-video of each system freely can be spread and is scheduled, cannot achieve interworking function, enumerate as
Under:
1. cannot achieve the communication of each equipment room inside naval vessel, for example command telephone can not be with list used in security personnel
Soldier schemes biography, intercom is linked up, to influence to command efficiency.
2. cannot achieve the intercommunication between the naval vessel using different frequency range ultrashort wave radio set, after sea police office merges, usually exist
The problem of ultrashort wave radio set is unable to intercommunication between constituent parts naval vessel influences the commander that forms into columns.Such as former fish-farming operation naval vessel ultrashort wave radio set makes
With fishing frequency range, former frontier policeman naval vessel ultrashort wave radio set uses police frequency range, and the two is unable to intercommunication.
3. bank base scheduling can only reach video conference terminal position personnel (captain/chief engineer), can not directly with tune
Degree " tip " location personnel (such as from the individual soldier of warship, cabin position personnel) carry out audio-video directly link up, thus acquisition less than
The in-situ data of " first-hand ", influences the result of decision.
SIP (Session Initiation Protocol, initiation protocol of replying) technology is first in mobile communication field
It introduces, realize the business such as IP voice-over, video and is uniformly controlled in IMS (IP multimedia) converged communication.Sip technique is answered extensively
For enterprise's visual scheduling, on certain advanced ships also based on SIP realize in take on the telephone it is (shortwave, ultrashort with outer logical equipment
Wave radio station etc.) comprehensively control, have no be applied to the utility model relates to ship-to-shore between audio-video integrated dispatch.
Summary of the invention
In view of the above-mentioned drawbacks of the prior art, the technical problem to be solved by the present invention is to provide be based on SIP skill
Art integrates the communication function of the subsystem respectively dispersed on ship, realizes ship-to-shore audio-video integrated dispatch.
In order to solve the above technical problems, the utility model, which uses such a ship-to-shore audio-video based on SIP, dispatches system
System comprising be set to ship business system in naval vessel, comprehensive video management platform, wireless image transmission individual-soldier system, boat-carrying view

Module completes the mutual conversion of RTSP signaling and SIP signaling, guarantees the pipe that RTSP video code flow is supported under Session Initiation Protocol framework
Reason.
The also outer logical equipment voice channel of the present invention is broadly divided into two classes, and one kind is half-duplex channel, as shortwave, ultrashort wave,
Wireless image transmission voice channel, one kind are full-duplex channels, as marine satellite, VSAT defend it is logical.To realize full duplex equipment and half pair
Communication between construction equipment takes following measure.One, to support half-duplex operation, flat touch control command terminal will in this system
Expanding external band PTT key handle, and PTT signaling data transfer function is supported in integrated communication control equipment, it is possible to provide it is right
The support of half-duplex operation mode.Two, to be adapted to half versus full-duplex interchannel when carrying out voice forwarding, this system
Come using the acoustic control triggering PTT transmitting-receiving mode based on VAD (Voice Activity Detection, voice activity detection) detection
Adaptation, basic principle is, when full-duplex terminal is given orders or instructions, carries out text hegemony by the DSP on processing platform, once assert the use
Family is given orders or instructions, then the PTT signal control signaling channel of automatic trigger semi duplex radio station goes out voice transmission, other situations are from turn
To receive words.
The present invention is docked using video output gateway with the interface of video conference terminal stream transmission, and then can pass through control
Video exports the output content of gateway, guarantees that bank base can see the control and monitor console picture of any position on ship, video monitoring video
(key position for monitoring device operation), can also be adopted the sound that need to monitor sound position by establishing Multi-Party Conference
Collect equipment and meeting is added, bank base is enable to hear the equipment operation sound at scene.
More than it should be understood that, only specific embodiment of the present utility model, but the protection scope of the utility model
It is not limited thereto, anyone skilled in the art can be thought easily in the technical scope disclosed by the utility model
The change or replacement arrived, should be covered within the scope of the utility model.
