Utility model content
The purpose of this utility model is to provide a kind of video conferencing system communicated with command centre for command car, to solve the problem of the transmission bandwidth existing for existing communication mode by wireless network bandwidth restriction.
In order to realize above object, the technical scheme that the utility model adopts is: a kind of video conferencing system communicated with command centre for command car, comprise and command the wireless network server of on-the-spot audio-video signal and the command centre's webserver for being located at the on-the-spot audio-video signal of fixing command centre receiving center for being located in command car to receive, this system also comprises the mobile terminal for being located in command car and is located at the fixed server of fixing command centre; The described command centre webserver and fixed server communicate to connect, wireless network server communicates to connect the uplink to realize commanding on-the-spot audio-video signal by the first communication link and fixed server, and mobile terminal communicates to connect the downlink transfer to realize the on-the-spot audio-video signal in center by second communication link and fixed server.
Described first communication link and second communication link are the wireless network of telecommunications/movement/UNICOM.
This system also comprises the audio/video decoder for being located at command centre, and this audio/video decoder and fixed server communicate to connect commands on-the-spot audio-video signal to carry out decoding to show to obtain.
The described command centre webserver is connected by wired network communication with between fixed server.
Described mobile terminal is movable computer or smart mobile phone.
The utility model utilizes the Wireless/wired network of existing comprehensive covering for the video conferencing system that command car communicates with command centre, the audio/video information of the audio/video information of moving vehicle and fixing command centre is accessed in fixed server simultaneously, the wireless network server of command car and mobile terminal realize the upper of data respectively by different communication links, downlink transfer, solve wireless routing transmission bandwidth to affect by wireless network bandwidth, what between fixing command centre and command car, realize that transmitting two paths audio frequency and video on same link cause does not meet because of wireless bandwidth, there is the situation that signal quality is bad, thus affect the problem of the fluency of information.
In addition, the platform that the audio frequency and video that fixed server erects a movement manage with fixing audio frequency and video unified monitoring, mobile command car and fixing command centre be respective access platform again, the bidirectional audio-video reached between fixing command centre and mobile command car transmits, and this system has that confidentiality is high, cost is low, the simple feature of Dynamic System.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the video conferencing system that the utility model communicates with command centre for command car.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described further.
Be illustrated in figure 1 the schematic diagram of the video conferencing system embodiment that the utility model communicates with command centre for command car, as seen from the figure, this system comprises for being located at the wireless network server in command car and the command centre's webserver for being located at fixing command centre, wireless network server receives commander on-the-spot sound, vision signal by microphone in camera in car and car, and command centre's webserver passes through sound, the vision signal at center camera and microphone receiving center scene, center; In addition, this system also comprises the mobile terminal for being located in command car and is located at the fixed server of fixing command centre; Command centre's webserver and fixed server communicate to connect, wireless network server communicates to connect the uplink to realize commanding on-the-spot audio-video signal by the first communication link and fixed server, and mobile terminal communicates to connect the downlink transfer to realize the on-the-spot audio-video signal in center by second communication link and fixed server.
