Description

Technical Field

[0001] The present invention relates to the technical field of display screen control systems, and particularly to an efficient and intelligent LED display screen control system. Background Art

[0002] Most modern flat panel displays use the spatial method to synthesize colors, and each pixel on the display contains sub-pixels that can generate the three primary colors. When the sub-pixel pitch is small enough, color mixing occurs to present various different colors. The sub-pixels of an LED full-color display correspond to light-emitting diodes of different primary colors (such as red, green, and blue). Under the control of drive signals, the three primary colors present various different colors through color mixing and form an LED pixel. During the process of an LED display showing an image, the pixel data of the video source can be completely mapped to the LED display one by one.

[0003] Currently, the common LED display screen control systems on the market mainly achieve the control of LED display screens through traditional synchronous or asynchronous control cards. For LED display screens produced by different manufacturers, the compatibility of existing control systems is poor, and often need to be customized and developed for specific display screens, increasing the development cost and time. Summary of the Invention

[0004] The purpose of the present invention is to provide an efficient and intelligent LED display screen control system to solve the problems raised in the above background art.

[0005] To achieve the above objectives, the present invention is realized through the following technical solutions: An efficient and intelligent LED display screen control system includes a PC background management system, a collection APP, and a transmission and control device. It returns violation tags and confidence values through a content detection algorithm, receives the collection tasks issued by the PC background management system, scans the QR code for collection, fills in new display screen information in the form that appears after the APP scans the code, and transmits the information to the PC background management system. The collection APP accepts the verification tasks under the PC background management system, and the APP verifies the used QR code by scanning and transmits it to the PC background management system after verification. The transmission and control device is connected to the LED screen and transmits the display content of the LED screen to the PC background management system in real time.

[0006] Optionally, the LED screen collects display information by posting a QR code.

[0007] Optionally, the PC background management system uses an OCR content recognition engine for text recognition and image analysis, constructs an optical channel processing architecture, separates the text and picture special recognition pipelines, establishes a text and picture association matrix, solves the text and picture composite violation scenarios, associates a dynamic feature library, covers the pure picture violation types, and uses a confidence threshold algorithm to classify and determine the violation content.

[0008] Optionally, the PC background management system mainly identifies whether the text and pictures contain pornographic, politically related and other inappropriate content.

[0009] Optionally, the PC background management system can turn off the LED screen with one key through the transmission and control device, and disconnect the video stream of the LED screen.

[0010] Optionally, the transmission and control device includes a networking module and a playback module, and the networking module controls whether the playback module plays through current.

[0011] Optionally, the PC background management system is connected to the networking module and the playback module through a shunt.

[0012] Optionally, the PC background management system can extract frames and upload the played picture content.

[0013] Technical effects and advantages of the present invention:

[0014] 1. The management unit can break through device differences and manufacturer restrictions, and centrally manage various LED devices. The management unit can not only strictly review the published content to ensure the accuracy and compliance of information, but also quickly suspend device playback in special situations such as emergency events and information error correction, achieving flexible and efficient control, and ensuring the stable operation of the LED display system and the security of information dissemination.
