【摘要】：随着我国进入到'十三五',我国经济又进入到一个新台阶,人民的生活水平也在不断进步,同时人民也越来越依赖电力能源,这就给我国电力相关部门提出了更高的要求—保证电力的安全性和稳定性,特别是像我国沿海地区,每年都会有数场台风的侵袭,因此要想保证电力的正常供应,就必须要保证变电站及其周边的安全,因此电力部门就需要一套能够实时的监控变电站的系统,当有电力无法正常供应的时候,电力部门相关人员能够在第一时间内知道发生问题的地点,随后能够立刻派相关维修人员过来维修。随着互联网行业的快速发展,现在的视频监控技术可以去实现变电站视频的监控,相比之前的视频监控系统,这样做不仅可以提高视频监控的稳定性,而且还可以缩减很多不必要的成本。该系统选用的是Linux操作系统,该系统所用的代码包含一个重要的性质——开源性,并且遵循着GPL协议[1],由于源代码被公开,因此任何人都可以在Linux操作系统上进行修改,非常方便。并且Linux操作系统在应用中表现出非常稳定的性质,运行过程中消耗的资源较少。该系统选用USB摄像头采集视频图像,USB摄像头中所用到的是V4L2驱动程序,该驱动程序在灵活性和稳定性方面具有很好的表现,该系统如果要做到实时的监控,那么这也意味着系统要处理的视频图像会非常多,因此需要选取具有较高压缩效率的压缩技术,该系统选用H.264编码技术,目前该技术具有很好的压缩效率。图像在压缩好后传输的过程中容易受到多方面因素的干扰,本系统选用RTP/RTCP传输协议,随后选用流媒体播放器VLC作为视频播放器,VLC可以做到视频的实时播放,而且还可以支持多种视频格式的播放,最后对该系统中的全部功能进行详细的仿真测试。
[Abstract]:As our country enters the 13th Five-Year Plan, the economy of our country enters a new stage, and the living standards of the people continue to improve. At the same time, the people are increasingly dependent on electricity and energy. This puts forward higher requirements for the power related departments in our country-to ensure the safety and stability of electricity, especially in coastal areas of China, where typhoons strike several times a year, so if we want to ensure the normal supply of electricity, It is necessary to ensure the safety of the substation and its surrounding areas. Therefore, the power department needs a system that can monitor the substation in real time, when there is electricity that cannot be supplied normally. Relevant personnel in the power sector can know the location of the problem within the first time, and then immediately send the relevant maintenance personnel to repair it. With the rapid development of the Internet industry, The current video surveillance technology can realize the substation video monitoring. Compared with the previous video surveillance system, it can not only improve the stability of video surveillance, The system uses the Linux operating system, and the code it uses contains an important property-open source, and follows the GPL protocol [1], because the source code is open. So anyone can make changes on the Linux operating system, which is very convenient. And the Linux operating system shows a very stable nature in the application. In this system, the V4L2 driver is used in the USB camera to capture video images, and the driver has a good performance in flexibility and stability. If the system is to be monitored in real time, it also means that the system will process a lot of video images, so it is necessary to select the compression technology with high compression efficiency, and the system uses H.264 coding technology. At present, the technology has a good compression efficiency. The image is easy to be interfered by many factors in the process of image transmission after compression. In this system, RTP/RTCP transmission protocol is selected. Then the streaming media player VLC can be used as the video player to play the video in real time, and it can also support the playback of various video formats. Finally, the simulation test of all the functions of the system is carried out in detail.
