I. Introduction The public security command center has higher and higher requirements for information display. The large-screen display system, as a communication platform for centralized information display, can display the computer graphic information, video conference and video surveillance signals of various monitoring systems in real time. Command, dispatch, negotiation, decision making and information feedback play an important role. The traditional large-screen display system mostly uses the large screen as a single display. When multiple screens are displayed together, the resolution of the content source is limited, and high-definition display cannot be realized on multiple splicing screens. The viewing effect of the command center application. At the same time, because the independent content is displayed on the wall, the information is scattered and isolated, and it is impossible to combine the massive alarm information, video surveillance information, police guard information, event scene information and high-resolution large-screen display system advantages to improve emergency command. Decision and resource scheduling efficiency. At present, the main problems faced by traditional public security command centers are: 1. How to use high-resolution representation of high-resolution maps associated with events: The high-resolution content source of the PGIS system matches the resolution of the large-screen high-resolution display system, and the clear display of super-high scores is performed; 2. How to improve the judgment and analysis efficiency of the police: through the geographic information system to locate the incident at the first time, and quickly link the video around the incident to realize the video implementation; 3. How to quickly grasp the police and accurately dispatch resources: It is difficult to understand the actual situation of the distribution of police resources in the first time, and it is difficult to confirm the appropriate police resources in the first time; 4. How to grasp the disposal process and result feedback in real time: It is difficult to grasp the real-time status of police deployment, it is difficult to monitor the entire disposal process and effect in real time, and it is difficult to make real-time response and deployment adjustment according to the changes in the field in time. Second, the system architecture and application advantages The ultra-high score display actual combat platform can effectively solve the problems of display and actual application. The system extracts various police resource data from the public security massive data through various types of data interfaces. According to the application logic of the command center, The logical relationship corresponding to various police resource data is sorted out, and the data processing technology and data rendering technology such as geographic operation, data analysis and data extraction are used to visualize the big data, and the super high score visualization server is used to realize the police data. It integrates with the big screen and presents the process of intelligent command and dispatch. It combines the PGIS system, business application and video surveillance with ultra-high resolution large-screen system, which can realize on-demand setting, one-click calling, fast assistant decision making, video command and dispatch, etc. Visual command and dispatch function. Hikvision super high score display actual combat platform system includes front-end monitoring front-end, mobile handheld police terminal products, such as individual soldiers, police services, law enforcement recorders, etc., wireless emergency control products such as vehicle forensics systems, wireless cameras, wireless base stations The video information obtained by the front-end products is integrated into the video hub center through the transmission private network to provide a video basis for visual command. In the back-end command center, a set of command platform, a data center, and a large-screen system are provided. Complete system solution. The visual combat platform system is shown in Figure 1. Figure 1. Visualization of the actual platform system The actual platform based on the super high score display has the following obvious application advantages: 1. Really super high resolution display Visualized actual platform system, relying on ultra-high resolution splicing large screen, can combine large screen resolution with limited physical resolution into ultra-high resolution splicing video wall, as a high-resolution, large-area display terminal, showing ultra-high resolution Electronic map, video surveillance, GPS equipment, command and dispatch business system, etc., its display resolution is the superposition of single-screen display resolution, the image display content is more abundant, the scope is wider, the image is more clear, avoiding the need to frequently drag the mouse In order to see the content of different areas. 2. The terminal and the big screen are WYSIWYG Ordinary computer display resolution is generally 1920*1080, and the resolution of the ultra-high-resolution visual scheduling system is often 10-50 times of the resolution of ordinary computer display. If the ultra-high-resolution visual scheduling system is directly displayed by ordinary computers, only A small part of the display system must be dragged with the mouse to switch to the rest, or directly to the large screen operation, which is inconvenient to use. The use of the ultra-high-scoring display method on the wall of the actual combat platform allows the user to directly view and operate the ultra-high-resolution visual scheduling system on the ordinary computer, completely synchronizing with the splicing large-screen display content. 3. Visualized scheduling of intelligent applications Based on the ultra-high resolution electronic map, the actual combat platform includes a rich command and dispatch combat function, fully integrated with the large-screen display system, and finally presents the user with an ultra-high resolution visual command and dispatch system, which can improve the alert judgment and confirmation efficiency. Improve emergency command decision-making and resource dispatching speed, and master the disposal process and disposal results in real time, which can effectively improve the ability of public security organs to predict and predict, dynamic control, on-site disposal capability and command support capability under dynamic and informatized conditions. Government emergency response and urban management. Third, the technical support of the super high score display The ultra-high-scoring display actual combat platform relies on the ultra-high-resolution video processor, adopts high-speed bus transmission technology and digital image processing technology, and the image data of the ultra-high-resolution video processor enters the system through the ultra-high-level access module, and passes the image data. The block processing is performed, and then sent to the output module through the high-speed backplane bus for output display, and the image synchronization technology, the decoding technology, the remote control technology, and the high-speed bus transmission technology are used in the whole implementation process. Maps or software over 10 million pixels can be displayed on the entire TV wall. Figure 2 is a schematic diagram of the relationship between 10 million pixel content and the TV wall. Figure 2.
