Description
Technical field
The utility model relates to the video-frequency monitor field, particularly the Internet video monitor.
Background technology
An important application of video monitoring system is exactly the safe city engineering, and the safe city engineering is that the nationwide of being intended to of Ministry of Public Security's tissue promotes the Important Project project that the urban public security monitoring is built comprehensively.Be intended to by technological means, with hit, prevention is broken laws and commit crime is purpose, satisfies the people's good hope humorous, that ask safety of seeking development, aspire for stability, sue for peace.Pass through network management, public security organs at different levels and relevant departments can monitor, browse, inquire about the on-the-spot realtime graphic in places such as being built up in the complicated place of public security, keypoint part, arterial street, the multiple location of case, critical junction, bayonet socket, the public security of understanding and grasping guarded region intuitively is dynamic, can accomplish fast reaction, effectively improve social security integrated management level emergency.
" 3111 engineering " is divided into tertiary structure: the first order is set up the control and command center in the municipal public security bureau; The second level is in branch office; The third level is in local police station or street, and three grades all require networking operation.
In the safe city project case history of current construction, owing to adopt stream media technology, and carry out centralized management.In this system, offer the vision signal that the rear end is based on the internet, these signals can not show on monitor or screen test.
The rear end display mode has following several:
One, at unit orderly rooms at different levels, computer is adopted in the monitoring point, and uses special-purpose decoding monitoring software or adopt the mode of IE browser to realize real time monitoring.Computer and Internet connection are easy, and be easy to operate, and shortcoming is that investment is big, display effect difference and do not support long time continuous working, and compatibility, computer virus etc. also can cause certain problem.
Two, adopt Video Decoder, network video signal is converted to composite video, and adopt monitor to show by video line.
Three, for Surveillance center: adopt industrial computer, and on machine the video decode card is installed, network video signal is through after the decoding of decoding card, and the output composite video signal shows via video wall again.While outputting VGA signal on the industrial computer is showing on the display or is showing on video wall.
This several should situation in, several defectives are all arranged:
1, at first be that cost is too high, the industrial computer that uses on the engineering involves great expense, and is equipped with miscellaneous equipment again, and the whole system cost is high.
2, screen is too little, computer display generally has only tens to twenties cun, can not be applicable to large scale display, adopt large-sized display device reluctantly, again can be and cause the insurmountable difficult problem of system because of compatibility issues such as resolution, definition and poor stability;
If 3, the 3rd adopt the curtain wall display system, then, become composite video signal through various device translates again because network video signal has originally compressed terribly, pixel is lost very serious, has caused image quality decrease etc.
4, the 4th is that operation is loaded down with trivial details.Because equipment is numerous, various device derives from different production again and produces house usually, therefore operates cumbersome.
The utility model content
The purpose of this utility model provides the decoding of a kind of lower-cost collection Internet video, real time monitoring, records a video, is controlled in the embedded type network video monitor of one.
Another purpose of the present utility model provides a kind of Internet video that is made of above-mentioned Internet video monitor and monitors curtain wall.
The technical scheme that realizes first purpose of the utility model is as follows:
A kind of Internet video monitor, comprise liquid crystal display screen and driver module thereof, also comprise the network decoding memory module, described network decoding memory module comprises ethernet module, digital signal processing chip, the RAM that is connected with digital signal processing chip and FALSH, hard disk and hard disk controller, the Internet video data arrive digital signal processing chip through ethernet module, hard disk links to each other with digital signal processing chip through hard disk controller, and the decoded vision signal of digital signal processing chip shows on liquid crystal display screen through the liquid crystal display screen driver module.
The technical scheme that realizes another purpose of the utility model is as follows:
A kind of Internet video monitors curtain wall, is made of many above-mentioned Internet video monitors, and described Internet video monitors that curtain wall also comprises the control desk and the network switch, and described Internet video monitor and control desk all are connected on the network switch.
Compared with prior art, the utlity model has following beneficial effect:
1, adopts embedded OS, reduced cost;
2, integrated Internet video decoder, digital hard disk recording, monitor are in one, and be easy to operate;
3, predeterminable multiple decoding process in FLASH is by the adaptive video data ground decoding of digital signal processing chip according to input;
4, adopt the network switch that the Internet video monitor is spliced into the supervision curtain wall, easily splicing, easily expansion;
5, under the situation that realizes said function, do not need to join IP video server and storage managing server in addition, system architecture is simple and direct, has reduced cost, and is easy to operate;
6, the monitor lcd curtain wall directly shows digital signal, need not an Internet video data transaction and become composite video signal, thus the image definition height that shows;
