【摘要】：视频监控系统是监测变电站运行环境和提升其信息化程度的重要平台,随着我国电力行业的迅猛发展,变电站视频监控系统发挥出越来越大的作用。然而,监控领域厂家众多,监控标准又未统一,导致各家的设备在对接时经常出现故障,极大地影响了视频监控系统的功能,为变电站长期运行埋下了隐患。针对上述问题,统一监控标准,规范通信接口,设计出一套合理的测试方案保证设备互联互通,是一项极具现实意义的课题。本文围绕这一课题开展工作,针对变电站的特殊应用环境,设计与实现了一种基于ONVIF(Open Network Video Interface Forum,开放网络视频接口论坛)协议的摄像机模拟测试方法。本文首先阐述了课题的研究意义,分析了视频监控标准的国内外研究现状及其测试方法,然后对本课题的相关技术进行了理论研究,并在此基础上开发了符合变电站需求的ONVIF扩展协议,完成了ONVIF协议软件测试平台和摄像机模拟器的设计。主要工作体现在以下几个方面:1.从功能需求和技术路线角度分析,确定了摄像机模拟测试方法的总体实施方案,扩展了三维定焦、物体移动侦测、视频遮挡侦测和OSD(On-screen Display,屏幕菜单式调节方式)字幕等ONVIF接口,并对各接口的参数进行了详细定义。2.完成了ONVIF协议软件测试平台的设计。根据被测对象的不同,分为客户端测试平台和服务端测试平台两部分,详细介绍了各主要功能模块的设计思路和实现方法。3.完成了摄像机模拟器的设计。从模拟真实摄像机的主要性能参数、多路视频流传输机制和事件触发机制三个角度入手,详细阐述了通过软件模拟真实设备的思路和具体实现过程。4.通过ONVIF软件测试平台和摄像机模拟器对视频监控设备的测试,验证了摄像机模拟测试方法的有效性。
[Abstract]:Video surveillance system is an important platform to monitor substation operation environment and improve its information level. With the rapid development of power industry in China, substation video monitoring system plays an increasingly important role. However, there are many manufacturers in the field of monitoring, monitoring standards are not uniform, resulting in the equipment in docking often appear fault, greatly affected the function of the video surveillance system, the substation for the long-term operation of hidden dangers. Aiming at the above problems, it is of great practical significance to unify the monitoring standard, standardize the communication interface, and design a set of reasonable test scheme to ensure the interconnection and interworking of the equipment. According to the special application environment of substation, this paper designs and implements a camera simulation test method based on ONVIF (Open Network Video Interface Forum, (Open Network Video Interface Forum) protocol. This paper first describes the significance of the research, analyzes the domestic and foreign research status of video surveillance standards and its testing methods, and then carries out a theoretical study on the related technologies of this topic. On this basis, the ONVIF extension protocol is developed to meet the substation requirements, and the design of the ONVIF protocol software test platform and camera simulator is completed. The main work is reflected in the following aspects: 1. From the point of view of functional requirements and technical route, the overall implementation scheme of camera simulation test method is determined, which extends 3D focusing, object motion detection, video occlusion detection and OSD (On-screen Display,). Screen menu adjustment) subtitle and other ONVIF interface, and the parameters of each interface are defined in detail. 2. The software testing platform of ONVIF protocol is designed. According to the differences of the tested objects, it is divided into two parts: the client test platform and the server test platform. The design ideas and implementation methods of the main functional modules are introduced in detail. 3. The design of camera simulator is completed. From the three angles of simulating the main performance parameters of real camera, the transmission mechanism of multi-channel video stream and the mechanism of event triggering, the train of thought and the concrete realization process of simulating real equipment by software are described in detail. 4. The ONVIF software test platform and camera simulator are used to test the video surveillance equipment, and the validity of the camera simulation test method is verified.
