Video conferencing and video surveillance can be effectively integrated to meet the needs of national security, emergency command, police inspector, digital justice, digital security, digital environmental protection, etc., to achieve fast and accurate visual scheduling, and to improve emergency incidents in various government departments. And the ability to cope with daily government affairs. This article refers to the address: http:// As a command center and monitoring center, video conferencing is responsible for communication, scheduling and supervision. Video surveillance, as a terminal acquisition, can realize on-site video and audio collection and provide command basis for the command site. The video conference site calls and controls any monitoring point image or video, and broadcasts the video surveillance and video conference screens to all the conference sites. It realizes the multi-party consultation, negotiation and unified deployment of the various departments. Arrange to avoid blind decision-making due to the inability to arrive at the scene in time, and improve the efficiency of unified analysis and decision-making. For example, when the government holds daily video conferences of various departments, it can call the video information of the jurisdictions of various departments for inspection or review, such as squares, railway stations, airports, gas stations, reservoirs, power stations, mines, shopping centers, entertainment venues, Internet cafes, hotels and other areas, through the real-time monitoring of images, video and alarm capture pictures, the relevant departments through the video conference joint inspection and remediation. Four stages of video conferencing integration monitoring The first generation of analog docking system outputs the image to the video conference terminal through the video surveillance decoder image, so that the surveillance image is broadcast in the conference. The second generation of video-based quasi-visual command and dispatch system, the video surveillance gateway and the MCU are integrated, and the video monitoring terminal is accessed through software. There is no professional dispatching seat. Only one monitoring platform client software is installed on the PC to perform simple video. Monitoring and management, using the monitoring and management mode of operation, requires multiple clicks for video scheduling, capacity is limited, and more than a certain capacity requires complex multi-machine stacking. The third-generation video surveillance and video conferencing dedicated gateway method solves the problem of video conferencing and video surveillance access. It can call multi-channel surveillance images and PTZ control of surveillance images through operations such as seating. However, it is necessary to increase the investment of the gateway device, and the dedicated gateway realizes the transcoding function and increases the fault point. Although the video conference call monitoring problem is solved, the integration open problem is not solved. The fourth-generation visual dispatching system seamlessly integrates video conferencing and video surveillance, without additional equipment, and can integrate other systems such as GIS and call center to form a complete digital system through visual dispatch management platform. As shown in Figure 1. Conference and monitoring of all-digital convergence of the fourth generation of fusion solutions Video surveillance and video conferencing integration unified interface The video conference supports conference template settings that are integrated between the conference terminal and the monitoring terminal. It supports one-click conferences and supports conference SMS notifications. As shown in Figure 2. Unified display and convenient control Converged conference support conference terminal and camera list display and control, support screen display mode setting, screen polling, broadcast mode, voice control, support for all video conference venues, send rolling subtitles and other functions. As shown in Figure 3. Conference image and surveillance image mixed multi-screen Support monitoring alarm image manually added to the video conference, support multi-channel 1080P or 720P, CIF surveillance images are simultaneously displayed in the video conference, support single-screen, multi-screen and other display modes, each screen display image can be switched or configured . As shown in Figure 4. Conference dual stream display monitoring and converged service The video conference supports VGA map pages, alarm information and other VGA pages to be displayed in all video sub-sites through dual stream synchronization. 3G, cloud computing, Internet of Things Video business brings new vitality The convergence solution using 3G technology supports mobile applications, and the 3G mobile phone constantly monitors images and joins conferences, which greatly expands the application scenario. The converged solution adopts distributed deployment and supports deployment on virtual machines to support cloud disk storage. The integration solution is connected through the middleware and the Internet of Things card and the M2M platform to realize the alarm linkage capture, which can greatly improve the intelligence of the integration solution. Convergence trend of conference and monitoring By combining conference and monitoring, the video surveillance capability of the surveillance system can be fully utilized, and video conferences can be used to enhance the emergency command capability of the video surveillance system, by introducing the monitored video into the video conference, and between the video conference and the monitoring system. Interconnection and control will provide a state-of-the-art monitoring and emergency command and dispatch tool.
Composite Insulator is an electrical device consisting of insulation section made of polymer materials and metal fittings, Silicone rubber is the most widely used polymeric insulation material for high voltage products. Composite polymer insulator can play an important role in overhead transmission lines. Electric composite insulator can be divided into: Suspension Composite Insulator,Composite Long Rod Insulator, Pin Type Composite Insulator and Line Post Composite Insulator.
As the replacement of porcelain insulators, silicone rubber composite insulators have many advantages:
