The network monitor for video monitoring solves problems that a computer or an NVR (network video recorder) needs to be configured between a network camera and a monitor, the cost is high, and comprehensive routing is complicated. The network monitor capable of realizing direct network video monitoring has an additional function of being directly connected with a network camera on the basis of a common liquid crystal monitor, omits a middle signal conversion procedure, reduces loss of signals to the utmost extent, and realizes networking and digitalization from a monitoring front end to a monitoring rear end. The technical scheme includes that the network monitor comprises a power circuit, a memory circuit, a liquid crystal screen, a router, a key control circuit, an interface control module and a microprocessor control module. The network monitor used for video monitoring is mainly applied to field real-time picture monitoring and short-time picture recording.
Description
Technical field
The utility model relates to a kind of network monitor, particularly a kind of network monitor that is used for Network Video Surveillance.
Background technology
In recent years, along with the development of Display Technique,, changed the LCD monitor of high definition into by common simulation CRT monitor as the monitor of supervisory control system terminal; On the other hand, the video camera of supervisory control system front end also develops into web camera (IP video camera) from analog video camera just fast.Though the camcorder technology of front end and the Display Technique of rear end have all obtained significant progress, the connected mode between the two is also very original, as shown in Figure 1.
Just grow with each passing day to the demand of high definition monitoring in monitoring market at present, and in the face of the development of front end high definition web camera, because therefore the terminal presentation facility that can embody high definition network monitoring advantage that can directly not link to each other accordingly all can only adopt the connected mode shown in the figure one.The shortcoming of this connected mode is explained as follows:
1. web camera is directly exported the AV signal to monitor.Because the definition of the CVBS signal maximum transmitted of AV signal is 575 lines (after removing blanking signals), therefore no matter how high the monitor resolution of terminal have, and also cannot reach the standard of 720p high definition.
2. web camera is by netting twine interface RJ45 output network vision signal, after soft decoding by computer or the decoding of network hard disk video recorder NVR, output AV signal or VGA signal, perhaps more clearly the HDMI/DVI signal to monitor.The effect of AV signal and web camera are directly exported the AV signal and be there is no two different herein.For the VGA signal or the HDMI/DVI signal of this moment output, though can reach 720P or more than the 720P, owing to need to be equipped with computer or NVR between web camera and monitor, cost is too high, and comprehensive wiring is loaded down with trivial details.
For these reasons, just need a kind of monitor can directly handle the network video signal of web camera output, realization front monitoring front-end truly is to networking, the digitlization of rear end.
The utility model content
The technical solution adopted in the utility model is to overcome prior art owing to need to be equipped with computer or NVR between web camera and monitor, cost is too high, and comprehensive wiring is loaded down with trivial details, the network video signal that provides a kind of network monitor that is better than video monitoring directly to handle web camera output, realization front monitoring front-end truly is to networking, the digitlization of rear end.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of network monitor that is used for video monitoring, comprise power circuit, memory circuit, liquid crystal display screen, router, key control circuit, it is characterized in that also comprising interface control module, microprocessor control module, wherein web camera module, router, interface control module, microprocessor control module, liquid crystal display screen are electrically connected in proper order, and power circuit output end, key control circuit output, memory module output are electrically connected with microprocessor control module input respectively.
Described web camera module comprises the multi-channel network video camera.
Described interface modular converter comprises PHY chip LAN8720.
Described microprocessor control module is a kind of in SOC chip, the ARM microprocessor.
From above-mentioned architectural feature of the present utility model as can be seen, its advantage is:
On the basis of existing common LCD monitor, increase the function of the web camera of directly plugging into, cancellation middle signal transfer process reduces the loss of signal to greatest extent, reduce the cost of supervisory control system, the monitoring image of direct display network video camera, realization front monitoring front-end truly is to networking, digitlization, high Qinghua of rear end.
Description of drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is the connected mode of traditional front-end and back-end.
Fig. 2 is the network monitor theory diagram.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Network monitor intends adopting the technology platform of Web TV, removes the part that monitor does not need on this platform, newly-increased needed function of network monitor and characteristic.
The specific design block diagram is as shown in Figure 2: comprise power circuit, memory circuit, liquid crystal display screen, router, key control circuit, interface control module, microprocessor control module, wherein web camera module, router, interface control module, microprocessor control module, liquid crystal display screen are electrically connected in proper order, power circuit output end, key control circuit output, memory module output are electrically connected with microprocessor control module input respectively, and wherein the web camera module comprises the multi-channel network video camera.Interface modular converter comprises PHY chip LAN8720.The microprocessor control module is that SOC chip, ARM etc. can handle a kind of in the processor of audio-video signal.Key control circuit is identical with the TV set controller function.
Preferred embodiment
The specific design process: the parallel data of multi-channel network video camera is followed the data formation network video signal that ICP/IP protocol converts serial form to by router, interface modular converter is decoded to network video signal then, become the signal of MPEG-4/H.264 form after the removal network encapsulation, the microprocessor control module is decoded to the signal of MPEG-4/H.264 form, the final LVDS digital signal that forms R, G, B drives liquid crystal display screen, carries out picture in the liquid crystal display screen top and shows.
Interface modular converter is finished physical layer and the two-part function of data link layer.Physical layer has defined data and has transmitted needed electricity and light signal, line status, clock reference, digital coding and circuit etc., and provides standard interface to data link layer device.Data link layer then provides structure, data error inspection, the transmission of addressing mechanism, Frame to control, provide to network layer the functions such as data-interface of standard.The data encapsulation that is about to the web camera module is a frame, sends to router, by interface modular converter data is sent in the microprocessor control module then.
Disclosed all features in this specification except mutually exclusive feature, all can make up by any way.
