Design And Implementation Of Highway Video Surveillance System And OSD

Modern security systems video surveillance has been developed to monitor all network security era. As the highway traffic video monitoring system a very important part of its development of national and regional stakeholders are highly valued.Video surveillance as an extension of highway Management Vision a powerful tool, hoping to intuitive, real-time to see the highway scene live, so that homes can understand the current highway road conditions, weather conditions, traffic operation conditions and traffic anomalies. With video surveillance, management of exceptions can be made quickly and accurately determine and develop solutions to the problems. Moreover, video surveillance can be exceptions to video, this time by the OSD display system, the location of additional information to facilitate analysis of future accidents.Currently there are different video surveillance manufacturers to comply with the production of different standards, not with the Internet, and this is not only inconvenient for the entire network of mutual access and retrieval, also made the community a great waste of resources. This paper described the highway video surveillance system is a comprehensive video surveillance management platform design. Specifically, the paper's main work is as follows:(1) In order to be able to access digital video computers, network transmission using Resilient Packet Ring technology, and if so, will need digital video in accordance with the encapsulated Ethernet frame format.(2) In order to ensure high-quality multi-channel video transmission at the same time, the need for image compression, cut and packaged by the Ethernet MAC layer to digital video transmission and exchange.(3) To facilitate the monitoring personnel immediate, accurate status of the discovery site, the video display, the paper is now very popular with OSD overlay technology stack including camera number, toll station, date and time and alarm signals and so on.(4) In order to monitor the conduct of officers for the mutual exchange of voice and data transmission. System uses 10-channel audio/data hybrid transmission, the proportion of audio data can be user-set.(5) In order to allow monitoring personnel to the unified management and command, the unified network management system to monitor. Network management system to complete by the embedded operating system, through the IIC interface, single-disc and audio and video/data to communicate with one disk.Through the testing and joint commissioning, the research to achieve the highway video surveillance system video, audio, data and other indicators of integrated transport. Playing out the great potential of video surveillance, video surveillance to improve the management of the expressway comprehensive coordination.
