【摘要】：作为智能电网的关键组成部分,电网视频监控系统在电网的生产、运行、维护、管理等方面举足轻重。近年来,随着电网视频监控系统规模的不断扩大,采用设备的厂家不断增多,但是由于不同生产厂商的视频监控系统设备的参考标准、功能及兼容性不一致,不同的产品之间在互联互通方面存在着一定的障碍。随着国网公司智能电网建设对电网视频监控系统标准化管理、统一监控、全局规划等要求的提出,对电网视频监控系统进行标准化规定与测试势在必行。本文在对四川电网视频监控系统架构、组成及功能深入调研分析后,结合国网视频监控系统标准,参与制定并完善了适用于四川的电网视频监控系统标准。据此进行需求分析,形成了四川电网视频监控系统检测平台的整体结构和功能组成。设计章节主要对检测平台(包括A接口平台模拟器、地市(县)级平台模拟器、站端智能辅助平台模拟器、视频处理单元模拟器)的各功能模块进行详细的分析、设计与实现。主要有:通信功能的实现,SIP协议和HTTP协议栈的实现,基于RTP的H.264格式视频流数据的打包、传输、解码播放、校验和保存的实现,MD5加密过程的实现等。在设计完成检测平台功能测试和协议测试的基础上,本文进一步对其功能进行优化,提出了自动测试、异常测试和压力测试的思想,对这三种测试方法进行研究,分析选取典型测试案例,同时进行设计与实现。检测平台设计完成后,在实验室和变电站现场与不同厂家的电网视频监控系统设备进行了大量的联调测试。在文章最后,给出了具体的测试结果,并对测试情况进行详细说明。实际测试验证了该检测平台的稳定性、可靠性、准确性、实用性,具有很好的应用价值。
[Abstract]:As a key component of smart grid, the video surveillance system plays an important role in the production, operation, maintenance and management of power grid. The number of manufacturers adopting equipment is increasing, but the reference standards, functions and compatibility of video surveillance system equipment of different manufacturers are not consistent. There are some obstacles in interconnection between different products. With the national network company smart grid construction of the grid video surveillance system standardization management, unified monitoring, global planning and other requirements, It is imperative to standardize and test the video surveillance system of power grid. After deeply investigating and analyzing the structure, composition and function of the video surveillance system of Sichuan Power Grid, this paper combines with the national network video surveillance system standard. Participated in the development and improvement of the standard of power grid video surveillance system for Sichuan. The whole structure and function composition of the video surveillance system detection platform of Sichuan power network is formed. The design chapter mainly discusses the detection platform (including A interface platform simulator, prefectural (county) level platform simulator, station terminal intelligent auxiliary platform simulator, etc. The function modules of the video processing unit simulator are analyzed, designed and implemented in detail, including the implementation of the communication function and the implementation of the HTTP protocol stack, the packaging, transmission, decoding and playing of video stream data in H.264 format based on RTP. On the basis of designing and completing the function test and protocol test of the testing platform, this paper further optimizes its function, and puts forward the ideas of automatic test, abnormal test and stress test. The three testing methods are studied, the typical test cases are analyzed and selected, and the design and implementation of the test platform are carried out. After the design of the test platform is completed, In the laboratory and substation field with different manufacturers of power grid video surveillance system equipment for a large number of joint testing. In the end of the article, the specific test results are given. The test results show that the platform is stable, reliable, accurate and practical.
