Research On Substation Video Monitoring System Based On S3C6410

As China enters into "13th Five-Year",the Chinese economy has entered a new stage,People’s living standards are also constantly improving,at the same time,people are more and more dependent on electric power.This has put forward higher requirements to the relevant departments of the electric power in our country.Especially in coastal areas of China,There are several typhoons every year.Therefore,in order to ensure the normal supply of electricity,it is necessary to ensure the safety of the substation and its surroundings.Therefore,the power sector needs a set of real-time monitoring system of Substation.When there is no electricity supply Power sector personnel can know where the problem occurred in the first place.Then can immediately send maintenance personnel over the maintenance staff.With the rapid development of the Internet industry,now the video monitoring technology can realize the Substation Video Monitoring.Compared to the previous video surveillance system.This can not only improve the stability of video surveillance.But also can reduce a lot of unnecessary costs.In this system,the operating system uses Linux operating system.In recent years in the field of embedded applications is the most Linux operating system.Its code is open source.And follow the GPL protocol.Because the source code is open.So anyone can modify the Linux operating system and Very convenient.And Linux operating system in the application of a very stable nature and less resources consumed during operation.The system uses USB camera to capture video images.USB camera is used in the V4L2 driver.The driver has good performance in terms of flexibility and stability.The system should be monitored in real time.This also means that the system will have to deal with a lot of video images.So it is necessary to select the compression technology with high compression efficiency.The system uses H.264 coding technology.At present,the technology has high compression efficiency.The image is easy to be interfered by many factors in the process of transmission.The system uses RTP/RTCP transmission protocol.Then select the streaming media player VLC as a video player.VLC can do real-time video playback.But also can support a variety of video format playback.Finally all the functions of the system are simulated in detail.
