A LED display control system and control method

Abstract

The invention discloses an LED display screen control system and control method, wherein the control system comprises a sending card used for receiving a video source, processing the video source, converting the video source into wireless signals, transmitting the wireless signals to receiving cards and sending control commands to the receiving cards; the receiving cards, wherein the number of the receiving cards is at least one, receiving ends of all the receiving cards are in wireless connection with the sending card, sending ends are electrically connected with a display circuit of an LED display screen, and each receiving card has a unique physical address; a setting module used for obtaining original parameters of the receiving cards, practically controlling the position and the area of the LED display screen according to the receiving cards, generating new parameters, associating the new parameters with the physical addresses of the receiving cards and generating the control command of each receiving card; and a control module used for controlling the receiving cards to display corresponding content according to the control commands. According to the invention, the LED display screen is operated in a wireless manner, the production and installation of plug-ins are saved, the maintenance cost and time are also saved, and the automatic control of the display screen is realized.

Description

technical field [0001] The invention relates to an LED display screen, in particular to a control system and a control method of the LED display screen. Background technique [0002] The traditional LED display control system is generally composed of two parts, the sending card and the receiving card. Due to the need to transmit a large amount of commands and video data, the data is generally transmitted by wire, such as optical fiber and Ethernet. [0003] Such as figure 1 As shown, the receiving card is placed inside or near the LED display screen, and multiple receiving cards are serially connected in a wired manner. The serial connection methods between receiving cards include S type, Z type or other methods. [0004] Since the sending card and the receiving card and the receiving card are all wired connections, then connectors are needed, which will cause many problems: [0005] 1. Connectors will increase the corresponding cost, and the connectors need to be inserted...

AI Technical Summary

Problems solved by technology

[0005] 1. Connectors will increase the corresponding cost, and the connectors need to be inserted and installed manually. When installing and disassembling a large display screen, the number of connectors is huge, resulting in a huge workload for workers and error-prone

[0006] 2. Connectors are prone to contact failures, resulting in unstable operation of the display screen

[0007] 3. The connectors are serially connected sequentially. When a connector fails, it will cause the back screen to work abnormally.

[0008] 4. The connection shape and position of the receiving card must be entered manually, which is time-consuming and laborious

[0009] 5. Especially for large-scale LED displays, multiple sets of control systems are required to complete the display control work, which is relatively complicated
