Abstract
|
Remote video surveillance system is more and more widely in the power system , it is an important part of the substation automation run . The text according to the \. \\Functional modules , first of all by Linux provides a set of dedicated API function to achieve on the USB camera 's driver call , enabling video image acquisition ; including using image frame index of the way and covered methods to complete the history of video storage . Secondly , in embedded systems transplantation Boa server using UDP / RTP protocol group to encapsulate the video image , and IP multicast network transmission of video images . In addition, command transmission between the decoder and PTZ PTZ camera control through S3C2410 development board . Finally , through the use of CGI technology to achieve a dynamic interactive features of the system . Debugging , all modules of the software functions have been realized . Software system design , the introduction of the image - based frame-level indexing method , greatly improves the efficiency of historical data retrieval ; due to data transmission using IP multicast transmission mode , greatly reducing the burden on the user increase in volume for a long time server ; addition , because a the video data is divided into several separate parts, and encapsulated in a different IP packets for transmission to solve the problem of packet loss . The solution of the above problems , and has a certain practical significance to improve the monitoring quality for real-time monitoring of the melting ice \In addition , the system can also be applied to some other area of video surveillance , intelligent community , banks, shopping malls and other places , with some commercial value .
