With the development of society, the military, armed police, and public security command centers are playing more and more important roles in modern information warfare. The command center can realize activities such as information integration, unified command, real-time command, remote conference, and speech report. The command center must not only meet the needs of real-time command in emergencies during non-war periods, but also implement real-time command and dispatch for large-scale and comprehensive events in wars and emergencies, so as to achieve breakthroughs in space limitations and greatly improve The reaction speed greatly improves the overall rapid response capability. So, in practical applications, what are the key technologies of the distributed visual management system? Large screen splicing function command center is often composed of multiple large screens (mainstream methods are LED large screen, DLP large screen, DID large screen), various signals are transferred to the large screen display in an intuitive way, providing a basis for decision-making . Therefore, the distributed visual management system must be able to support LED large-screen splicing, DID large-screen splicing, and DLP large-screen splicing. The equipment used should preferably support various large screens at the same time. Signal seamless switching Non-seamless switching system, every time you change a signal source, the big screen will be black for a few seconds, which greatly affects the use. Especially if there are high-level leaders visiting, if the signal is black, it will cause unpredictable bad consequences. OSD quickly switches the signal source of the command center, often there are hundreds of channels, conventional equipment, through the central control page or computer software page to call, find the required signal source from hundreds of signals, and then switch to the large screen , Often takes tens of seconds. If it is an emergency, tens of seconds will have very serious consequences. Therefore, the signal must be quickly switched by OSD, and the signal can be retrieved within one second. KVM seat management is often an operator who manages multiple signal sources. In front of the operator, multiple displays are equipped, but only one set of mouse and keyboard is equipped, which is the introduction of KVM function. The actual operation should be that the mouse can cross the monitor arbitrarily, and enter the corresponding computer for operation. Permission setting management different operators manage different areas of the screen. The highest authority administrator can manage all screens. There must be allocation of various permissions. In actual projects, there should be temporary permissions so that others can take over the work when the operator leaves the seat for a short time (the temporary permissions must be immediately invalidated after the operator returns). The important work of the business collaboration function is often not completed by an operator. Each person completes a part of the work and is finally reviewed by the administrator. After the review, it is put on the big screen. Signal interconnection and intercommunication The distributed visual management system must be able to communicate with the leadership office, multifunctional meeting room, and even remote meeting rooms in the building. Modular function expansion facilitates the expansion of other functions, such as extended recording and broadcasting, and direct recording of important signals. For example, the automatic call of extended alarm signal, when the alarm signal is triggered, the corresponding signal will be automatically put up on the big screen, and the automatic call does not require any manual operation. For example, the introduction of monitoring of the surrounding environment, PM2.5, temperature, humidity, lighting and other environmental information monitoring. The system stability command center often runs 7*24 hours, and the requirements for stability are very high. In the early days, the matrix + splicing processor was used to build. In the early days, they were all centralized equipment. The biggest drawback of this type of equipment was a small problem. It required the entire machine to be powered off for maintenance, which was equivalent to the entire system shutdown. At this stage, using distributed can perfectly solve this problem. Decentralized distributed, the maintenance of any node does not affect the entire system. (Decentralized distributed, must not use any server, otherwise it is pseudo-distributed, once the server fails, the entire system will be paralyzed) Ultra HD 4K signal supports 4K signal access, except for 4K conference cameras and 4K computer signals In addition to the source, there is also the access of 4K H.265 IPC cameras. The remote visualized operation interface must have a real-time preview, and the previewed information will be put on the big screen. Do not arbitrarily call information to interfere with decision-making. The operation should be simple, use drag and drop on the screen. The operation interface must be able to be installed on a handheld tablet for easy operation by the operator or leader. The distributed integrated management system is dominated by command technology and information technology, and fully utilizes modern communication technology, network technology, automation technology, electronic monitoring and other advanced technologies to build a data transmission network as the link, computer information system as the support, and audio processing. , Video splicing processing, network transmission, KVM collaborative management, HD recording and broadcasting, POE power supply, environmental monitoring, centralized control and other functions in a modern, networked, intelligent processing platform. At present, the distributed integrated management system has been widely used in the government, military, armed police, and public security command center systems.
