With the advancement of China's smart manufacturing in 2025 and the rise of safe and smart cities, the application of LED displays in the field of high-end displays has become more and more extensive. In addition, the pace of transformation and upgrading of LED display manufacturers is getting faster and faster, which invisibly promotes the explosion of the LED display market. Is there a solution for LED display in the emergency command center? The following is a brief introduction by Winbond Ying Optoelectronics LED display manufacturer.
The emergency command center integrates various data resources, manages and calls the multi-service platform and computer graphics signals of the command center in a unified way, in order to make emergency decisions quickly and efficiently, call multiple data quickly, and respond to emergencies accurately and efficiently. The event provides favorable business support. Moreover, the LED display screen can be enlarged, reduced, full screen, split screen, or displayed in the form of picture-in-picture on the emergency call center access platform, the front-end display layer of the emergency call platform and other business platforms. The emergency command center involves multiple links and puts forward higher requirements on the stability and safety of the system. All these put forward higher requirements for the LED display produced by the LED display manufacturer.
The LED display system of the emergency command center includes the organization of comprehensive emergency treatment in emergency situations, the establishment of office facilities at the command site, and the provision of hardware equipment for smart meetings. Its solutions include system stability, scalability, reusability of places, and ease of management. Among them, the demand analysis is as follows:
LED display manufacturer
1. Highly stable.
Because the emergency command center is formed by the integration of multiple data resources, the multi-service platform and the command center’s computer graphics signals are concentrated to achieve unified management and calling. When the command center fails, other links will also have various failures. Therefore, the emergency command center needs a high-reliability and high-stability hardware system.
2. The analog and digital signals are mixed together.
Because different devices require different signal access, such as the CVBS signal source of the old device, HDMI, VGA signal source, the new digital monitoring signal source, etc., the front end of the command center system needs an analog signal, and it also needs to be connected to the computer and Network video signal is compatible. However, due to the cross-aggregation of multiple systems and excessive stacking of single equipment, problems such as complicated wiring, cumbersome system control, large equipment occupation space, and many faulty nodes. Therefore, when wiring and selecting models, not only the mixing of analog signals and digital signals, but also the coordination of various wiring links must be considered to avoid signal interference and other problems.
3. Visual scheduling and preview playback of signal images.
If the command center computer cannot realize the real-time visual scheduling of signal images, the preview of each signal, and the content displayed on the LED display, it will cause a lot of operating errors. In addition, there are many monitoring needs to achieve preview and playback functions, which can greatly increase the ability of the command center to accurately control cases.
4. Realization of multiple control methods.
Only one person can operate an ordinary computer, and the seat is also fixed. However, the emergency command center needs to work collaboratively in many projects and links, which puts forward new requirements for the operation of the equipment. In order to meet the requirements of the command center for rapid response to emergencies, a unified and convenient operation method is required.
Program features: The emergency command center adopts LED display screens. Because it is viewed from close range and the image display effect is relatively high, the LED display screens generally installed inside the command center are small-pitch LED displays. The display content includes video conferencing, visual command, video security monitoring, integrated multimedia, digital business, scientific research and teaching, integrated control, etc., in order to realize the information sharing and interconnection of various services. Therefore, the following 6 points need to be completed.
1. Highly stable.
The device adopts FPGA full hardware structure and no operating system, which avoids blue screen and crashes to a large extent. Moreover, the modular board design can support hot-swappable functions. When one of the boards has a problem, it can be replaced in real time without shutting down or powering off, without affecting the transmission of other lines. In addition, in order to ensure that the screen can work continuously for 7*24 hours, Winbond's LED display manufacturer has designed a dual backup function of power and signal for this purpose. In other words, after one power supply or signal has a problem, the other power supply or signal will directly replace the normal operation without affecting the normal operation of the screen.
2. Compatibility.
The emergency command center is accessed through a variety of equipment and needs to be compatible with various signal sources. For example, VGA, HDMI, DVI, SDK and DP, etc., which require the video processor to be compatible with multiple signal sources, and then converted into a signal that the LED display can receive. It has achieved interconnection and information sharing with multiple display systems such as security, monitoring, public transportation, and fire protection.
3. Integration.
Realize the centralized control of the LED display screen and peripheral equipment, and the design of the corresponding operation interface is more user-friendly. Through the touch screen or touch screen all-in-one machine, the control of any computer on the network is realized. It can realize the synchronization of network video conference, remote control, PPT presentation, remote command and other functions.
4. Flexible operation with multiple control methods;
The conventional control center is managed by a single personal PC, and the command center is set into flexible multiple control methods to adapt to different signal access and multi-platform access. Such as personal computer, tablet computer, desktop control keyboard, mobile wifi control and so on. The client software can realize real-time display of the content displayed on the LED display screen, and can perform operations such as plan extraction, unified switching of multiple signal sources, and cloud platform control. Moreover, multi-user operation requires authority control to define the access operation authority of different users. And it runs at the same time, and meets the priority control of those with higher authority. Those with the same authority have the first control. In this way, problems such as system misoperation and network jams can be avoided to a large extent, thereby improving the operating efficiency of the system.
5. Large-capacity signal input and output.
The software can support multiple operations of image windows and processor application windows, including free movement and zooming, picture-in-picture, attribute settings, overlay, window opening/closing, window roaming, and so on. Operators can perform more intuitive and precise operations according to their needs. These operations must satisfy multi-signal display and realize functions such as multi-signal access display. Software and equipment are required to support large-scale signal input and output.
6. Planning and preparation management.
The large-screen operation can realize the functions of preparing, deleting, adding, modifying, updating, and saving the plan, and realizes the pre-arrangement of all display screens. For example, the size of the window, the position of the display signal, zoom, etc., and the existing display scheme can be called at any time. It also provides shortcut keys to call the plan and automatic execution of the plan, which can be triggered according to the needs of time and events, and realize functions such as intelligent automatic display of the screen.
The above is a brief introduction of Winbond Ying Optoelectronics LED display manufacturer to the emergency command center LED display solution. Contains demand analysis and program characteristics, and the emergency command center can also meet the functions of high stability, compatibility, integration, flexible operation, multiple control methods, large-capacity signal input and output, and plan management. Of course, different emergency command centers require different functions. Therefore, LED display manufacturers need to develop different solutions for different command centers.
