Embodiment
In order to make content of the present invention be more likely to be clearly understood, below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
As shown in Figure 1, a kind of transmission of video monitoring system, described transmission of video monitoring system comprises at least one camera 1, shunt 2, video compressing module 3, video loop module 4, cache module 5, host computer 6, communication module 7, control end 8, video server 9, network 10, client 11, described camera 1 connects shunt 2, and camera inside comprises video acquisition module 41 and video record module 42, camera has the function of video acquisition and storage, can store the video data of certain capacity.Described shunt 2 separates two-way, and connect video compressing module 3 and video loop module 4 respectively, cache module 5 is connected with video compressing module 3.By the setting of video compressing module 3 and loop module 5, jumbo video is compressed, be convenient to store, decrease volume of transmitted data; Carry out loop play by video loop module 4 pairs of videos, correct and delete useless video.Described video compressing module 3 is interconnected with cache module 5, and cache module 5 is connected with video integration module 15, is controlled by the speed of cache module 5 pairs of video data transmission.Described host computer 6 is connected with cache module 5 and video integration module 15 respectively, and video integration module 15 carries out packing process to all treated images.Described video integration module 15 is connected with control end 8 by RTP or RTCP communications protocol, and video integration module controls packed image transmitting to control end 8.
Further, this system is also provided with communication module 7, and described communication module 7 is connected with control end 8 by ICP/IP protocol, arranges like this, is convenient to Received signal strength.Described host computer 6 is by network 10 connection control end 8.Described control end 8 is interconnected with video server 9, and described video server 9 inside comprises client thread pond 41 and control end thread pool 42.Client thread pond 41 is connected by Transmission Control Protocol with client 11.Described video server 9 is interconnected with client 11, and image information is passed to client, and described client 11 Connection Cache module 12, cache module 12 connects decompression module 13, and decompression module 13 is connected with multiple display device 14.Cache module 12 pairs of video datas rationally store, and reduce data transmission bauds.The view data of decompression module 13 to packing decompresses according to corresponding algorithm, then sends to multiple display device 14.Wherein, multiple display device 14 comprises video wall, video terminal, display screen, is mainly used to show the video information received.
As shown in Figure 2, described network 10 comprises wide area network 61 and local area network (LAN) 62, wide area network and local area network (LAN) can respectively with video server 9, also can be connected with router 91, signal transmission to client 11, control end 8.
Further, this transmission of video monitoring system comprises control end 8, video server 9 and client 11.Video server 9 can cross over local area network (LAN) 61 and wide area network 62, and the video source of control end 8 can be the control point in local area network (LAN) 61 and wide area network 62, and client 11 also divides local area network (LAN) and wide area network two kinds.Video server 9 utilizes fixing tcp port to intercept the request of the client-access from local area network (LAN) and wide area network, hear that the request of client-access just connects afterwards, open up new TCP end and set up communication with client, send video source signal to client simultaneously, client selects a video source to set up the order of monitoring connection, additional receptive address and port number information, the network address of server analysis client and port, determine client belonging network character, then by connection request pass down the line to video source, when passing on connection request, server can send network address and the port information of video data receiving terminal simultaneously, when client is positioned at local area network (LAN), this network address and port point to client, when client is positioned at wide area network, this network address and port point to server, video data need forward through server, video server is through the network address of receiving terminal and port information, send video packets, directly or be forwarded to monitor client through video server, in monitor procedure, client and control end are kept in communication with video server all the time, resolved by video server, pass on and processing command, system is finished the work thus.
The video source collection of control end has various ways, can pass through Embedded video acquisition plate data acquisition, but this cycle mode development time is long, and cost is high.This Systematical control end program needs to register on video server after starting, each road video has a unique sequence number to identify on video server, client sends transmission command to video server by this sequence number, determines whether control end responds and how to respond by video server.System utilizes coding and decoding video algorithm to complete video data process, requires video packets of data to send to control end by network, store in control end capturing video to file according to RTP or rtcp protocol, sends video file to video server.
In addition, client-side program operates in the monitoring client computer of local area network (LAN) or wide area network, carries out the easy to operate conversion realizing various video, the parameter adjustment of remote camera by special interface, send the request of recorded video file, receive the functions such as recorded file from video server.
The present invention is as follows by a kind of transmission of video monitoring system practical function: the first, configuration image size, data format and relevant parameter, and carry out initialization, the control such as to wake or restart up, the second, mesh parameter is configured, as arranged the IP address of video server, listening port etc., the 3rd, request video record, by arranging, video source can timed recording, and store video material, retrieves when needed.Four, real-time recording transmission is asked, for the client of local area network (LAN) or wide area network provides real-time monitored picture.Five, network access authority is set, for avoiding aggressive reaction, meets confidentiality requirement, can arrange server, shield unwarranted access.
Be only specific embodiments of the invention above, but the present invention is not limited thereto, for the person of ordinary skill of the art, under the prerequisite not departing from technical solution of the present invention, the distortion made should be considered as belonging to scope.
