[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.
