Fig. 1 is the theory diagram of system's preferred embodiment of real-time Transmission multi-medium data in the digital clustering communication system of the present invention.
Fig. 2 is the flow chart of the method preferred embodiment of real-time Transmission multi-medium data in the digital clustering communication system of the present invention.
Embodiment
In order to make technical problem to be solved by this invention, technical scheme and beneficial effect clearer, clear, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
Fig. 1 shows the system of real-time Transmission multi-medium data in the digital cluster system of the present invention.This system comprises colony terminal 10, dispatching desk 22 and is positioned at media server 20 on the dispatching desk 22, colony terminal 10 is for after being registered as validated user to media server 20, communicate with media server 20, and the Real-time Collection multi-medium data is also encoded, and sends to media server 20; Media server 20 is used for the multi-medium data behind reception and decoding set group terminal 10 codings, and decoded multi-medium data is play in real time.Media server 20 is the servers that have fixed ip address on the internet; Dispatching desk 22 is used for the dispatcher and controls communicating by letter between media server 20 and the colony terminal 20, the transmission of multi-medium data and the real-time broadcast of multi-medium data.In digital clustering communication system of the present invention, media server 20 communicates with dispatching desk 22.
Therefore the dispatcher can understand field data clear, intuitively, and resource is reasonably allocated.Colony terminal 10 has unique ESN or MEID, and colony terminal 10 is registered to media server 20 with this ESN or MEID.
Simultaneously, the upgrading that the present invention only need to carry out at existing colony terminal and dispatching desk need not to introduce or change too much hardware content, thereby as far as possible under prerequisite cheaply, has realized the real-time Transmission of multi-medium data, and the compatibility of system is very strong.
Fig. 2 shows the method for real-time Transmission multi-medium data in the digital clustering communication system of the present invention.Describe the process of the inventive method in detail below in conjunction with Fig. 1, Fig. 2, the method is utilized colony terminal 10 and the media server 20 that is positioned on the dispatching desk 22 is realized, may further comprise the steps:
3G network or 4G Internet Transmission can reach faster transfer rate, the preferred 3G of the above-mentioned wireless network of the present invention or 4G network.At present, there are various standards in 3G network, such as TD-SCDMA (Time Division-Synchronous Code Division Multiple Access, TD SDMA), WCDMA (Wideband Code Division Multiple Access, Wideband Code Division Multiple Access (WCDMA)), CDMA2000 (Code Division Multiple Access 2000, CDMA 2000) or WiMAX (Worldwide Interoperability for Microwave Access, worldwide interoperability for microwave access).Though present patent application day the 4G network also be in development, people are unremitting to the pursuit of network transfer speeds, even the Internet Transmission standard of 5G, 6G network or other high-speed transfer that may occur in the future, all should be this just scopes of protecting of invention.
After the carrier of colony terminal 10 reached the spot, colony terminal 10 adopted internal or external 12 pairs of multi-medium datas of multimedia collection device (video, audio frequency) to gather.Because the data volume of multi-medium data is larger, colony terminal 10 internal or external 14 pairs of multi-medium datas of multimedia coding device are encoded.
Step 104, described media server is decoded to the multi-medium data that receives, and plays in real time.
20 pairs of multi-medium datas that receive of media server are decoded, thereby have realized the effect of real-time playing multimedia data.The dispatcher watches multi-medium data in real time by dispatching desk, thereby understands in real time field data, is convenient to the dispatcher to the scheduling of resource.In addition, media server 20 can be set up with a plurality of colony terminals 10 simultaneously and communicate by letter, and receives the multi-medium data that 10 transmission of respective cluster terminal come.The dispatcher can offer a plurality of windows at dispatching desk and monitor simultaneously the dynamic of Different field, allows the dispatcher that various field datas are had an integral body, get information about.
Preferably, be voucher or the file data that makes things convenient for some event, in the time of media server 20 receiving multimedia data or afterwards, media server 20 can carry out multi-medium data automatically all preserving, or the dispatcher optionally preserves multi-medium data by dispatching desk.
Need to prove, communicating by letter between colony terminal 10 and the media server 20 can be radio communication, but is not limited to this.
Above-mentioned explanation illustrates and has described a preferred embodiment of the present invention, but as previously mentioned, be to be understood that the present invention is not limited to the disclosed form of this paper, should not regard the eliminating to other embodiment as, and can be used for various other combinations, modification and environment, and can in invention contemplated scope described herein, change by technology or the knowledge of above-mentioned instruction or association area.And the change that those skilled in the art carry out and variation do not break away from the spirit and scope of the present invention, then all should be in the protection range of claims of the present invention.
