Multi-screen parallel massive information display system

Abstract

The invention provides a multi-screen parallel massive information display system. An integral splicing wall is divided by the system with four screens as a unit, each four screens are controlled by an accessory node controller, and the accessory node controllers are connected with a master node controller through a high-speed internet. Under unified allocation and organization of the master node controller, external massive data (including analog video signals, digital signals of a computer and the like) are transmitted to the high-speed internet after quantization and digital processing and finally transmitted to the accessory node controllers, and images are parallelly rendered to a video memory by the accessory node controllers and displayed on a high-definition splicing display screen. The system comprehensively applies the CPU (central processing unit)+CPU parallel processing technology, the cloud computing technology and the high-speed network technology, so that the massive data which cannot be processed and displayed by a traditional system are quickly displayed in real time.

Description

Technical field [0001] The invention involves communication and computer fields, especially a multi -screen parallel mass information display system. Background technique [0002] At present, the mainstream information display system of the market uses a centralized control computing method to control the display unit. With the continuous development of technology and the user's requirements for product performance and display effects, it continues to improve. [0003] The existing information display system uses a centralized control computing method to control the display unit.That is, all input images must be connected to the video controller, and all output images are output by the video controller.The core components of this processing method are image spiers. Most of the equipment is designed with pure hardware structure and no operating system.The decoding and rendering work of the entire large -screen display image is concentrated in the image splicter. The system has poo...

AI Technical Summary

Problems solved by technology

[0005] (1) It is unable to process and display the user's large amount of data information, and at the same time, it cannot be compatible with new image input methods on the market;

[0006] (2) The system function combination, display, partition, and image exchange capabilities are relatively poor, and the input and output image matrix exchange capabilities between the same video controller are relatively good. When multiple video controllers are configured with a large number of screens, the two The matrix switching function between the input and output images of different video controllers is relatively weak; the general functional partition is based on the video controller, and basically does not support any combination or partition of input and output images between different controllers;

[0007] (3) The stability and reliability of the system are not high. At present, the video controllers of mainstream manufacturers are still based on industrial computers, so it is a severe test for the stability and reliability of the system. Especially for large-scale display systems, a If the video controller (such as output 32 channels) fails, the 32 screens may not be displayed normally, and maintenance is very troublesome. It is necessary to take out all the image input cards and image output cards in the video controller; on the other hand, the system Online real-time redundancy cannot be achieved;

[0008] (4) The scalability is poor, and it cannot meet the user's requirements for upgrading and transforming the display system. When the user proposes to expand on the original basis, the existing technology can only be dismantled and rebuilt;

[0009] (5) The system is not easy to maintain and upgrade

Due to the enlargement and reduction of the image of the traditional video controller, the conversion of the image format, and the image processing method are basically completed by the image input and output card, so its software is solidified in the image input and output card, and cannot be processed by pure software. The update realizes the system upgrade
