Emergency command center LED large screen display system scheme

The positioning of emergency command center should be to integrate multiple data resources, collect multiple business platforms and computer graphics signals of command center for unified management and call, so as to provide favorable business support for emergency decision makers to quickly access multiple data and deal with emergencies accurately and efficiently.The large-screen display system serves as the front-end display layer of emergency command center access platform, emergency command platform and other business platforms. The display effect directly affects the display of business platform functions and indirectly affects the work efficiency of command and dispatch.

The LED display system of the meeting place of the emergency command center includes the office facilities and intelligent meeting hardware equipment of the organization, discussion and command places and equipment places for comprehensive emergency disposal during emergency time.Solutions from the venue environment to the intelligent conference system design and construction of the entire solution.Solution features:

(1) venue reusability.In wartime, it is an emergency command place or emergency duty room; in peacetime, it is a multi-functional meeting room, training and drill room or duty lounge

(2) high stability and reliability of the system.The whole system supports online diagnosis, upgrade and replacement, and the design mode of front-end display and back-end control makes fault diagnosis extremely convenient

Easy to manage, easy to operate.The system supports friendly Chinese interface, conference venue audio and video switching and distribution, electric projection screen, electric curtain, projector, DVD player and other centralized and unified control through the central control system, which can facilitate the convening and management of meetings.

(4) strong scalability.The system supports multiple cascades, which can expand the scale of the conference to hundreds of thousands of sub-venues.

Second, demand analysis

The staff of the command center need to monitor graphic information from computer software, video monitoring of important parts and real-time communication with the duty room. Therefore, there are the following requirements in the construction process:

1. Visual scheduling, preview and echo function of signal image

If the computer in the command center cannot preview all signals and the contents displayed on the big screen in real time, it will lead to a lot of misoperation. The command center needs to conduct precise command and dispatching for the whole area, and the function of premonitoring and echo is particularly important

2. Mixed application of analog signal and digital signal

Given the need to use the old equipment CVBS signal source, VGA signal source access, a new digital monitoring signal access, therefore in the command center system front-end analog signals, with computer signals and network video signal, cross convergence between multiple systems, a single interface device stack is overmuch, cause wiring complexity, complex system control, equipment take up the space is large, increase fault nodes and so on various aspects of the problem.

3, flexible control of a variety of control methods

According to the general policy of information construction of control center, there are new requirements for the control mode of equipment.Traditional PC independent control, single control personnel, fixed seats, can not meet the requirements of the control center to respond quickly to emergencies, need unified, convenient control mode.

4. High stability

The command center is a department to prevent and deal with emergencies, which requires a highly reliable and stable hardware system, and there will be a huge risk for any outage.

LED display system, small spacing to assume command center multi-functional, comprehensive application of applications including the daily work of scientific research and teaching, video security monitoring system, video conferencing system, multimedia system, control system, visual command system and digital business construction, realize the business platform information connectivity, etc.

1. Integration

Realize centralized control of large-screen display system and peripheral equipment, humanized operation interface design, realize control of any computer in the network by touch screen or all-in-one machine, including PPT presentation, remote configuration and operation, etc.

2. Input and output of large-scale signals

Signals more, achieve more, according to the signal into a large screen control software support image window and signal processor application window of various operations, including window open/close, attribute set, move freely zoom, stack, and realize the window on the wall splicing any roaming, operators can operate more intuitive and accurate.

3. Flexible operation of multiple control modes

A variety of control methods work together to get rid of the limitations of traditional control methods.With PC, tablet computer and desktop control keyboard, the client software can display the contents being displayed on the big screen in real time, and can carry out pre-plan retrieval, unified switching of multiple signal sources, head control and other operations.Multi-user operation, with the function of authority classification, can customize the access and operation permissions of users.When operating at the same time, priority control is given to those with high permissions, and priority control is given to those with the same permissions who log in first.Adopt authority classification, can avoid the wrong operation when many people control, thus affecting the work efficiency.

4. High stability

The equipment adopts FPGA hardware architecture, no operating system, no computer crash, blue screen, virus invasion and other common problems.Board modular design and support hot plug, when the board card is damaged without shutdown, can be replaced in real time, does not affect the transmission of other lines.Hot backup redundant power supply, when the first power supply failure, the equipment does not need to shut down, automatically use the backup power to continue to work.

5. Plan management

It can easily realize the preparation, saving, modification and deletion of scene and plan, and realize the pre-arrangement of all display screen (setting the window size and position of display signal, and calling the existing display plan at any time). It supports the use of "hot key" (shortcut key) to quickly call plan.Support automatic execution function of preplan, which can be triggered according to time or event to realize automatic display of screen.

6. Compatibility

Multiple sets of display systems can be interconnected with the large-screen display systems of fire station monitoring system, public security bureau monitoring system and traffic management bureau monitoring system.
