Wireless data transmission and control method and device, electronic equipment and storage medium

Abstract

The invention relates to a wireless data transmission and control method and device, electronic equipment and a storage medium. The method comprises the following steps: a signal and / or a video is sent to an acquisition card in a wired transmission or wireless transmission mode; the video is distributed to a receiving card corresponding to the LED display module after being processed, and signalsare sent to the receiving card through a plurality of sending ports; data from one sending port is selected to be received; after the signals are received, the signals are transmitted among the receiving cards in a one-in one-out communication mode to form an annular closed circuit, and meanwhile control signals are transmitted in the opposite direction; and the received signal is displayed on the LED display screen. The invention further comprises a wireless data transmission and control device, a plurality of mobile video sources can be timely, accurately and clearly displayed on the LED display screen, and the wireless data transmission and control device can be applied to live broadcast. According to the invention, the load of the whole system is reduced, the running speed and the anti-interference capability of the system are improved, and the use cost is saved.

Description

technical field [0001] The invention belongs to the technical field of wireless data transmission and control, and in particular relates to a wireless data transmission and control method and device thereof, electronic equipment and a storage medium. Background technique [0002] In the modern business environment, wireless data transmission and control technology has been applied in the field of LED display data transmission and control. In the prior art, the sending card directly wirelessly broadcasts the video data packets to all receiving cards that make up the LED display module, and each receiving card obtains the corresponding video data packets according to its own hardware identification or loading position number, and After being driven and controlled, the respective loading areas are displayed on the corresponding modules; the sending card processes the video source and then connects to a wireless transceiver module, and each receiving card is equipped with a wi...

AI Technical Summary

Problems solved by technology

One sending card corresponds to the receiving cards that make up all the display modules of the LED display, forming more wireless data channels, which are likely to cause interference with each other, and because of the interference, the number of receiving cards that can be carried by the sending card is ultimately limited

The wireless transmission method based on WIFI or WHDI technology will cause interference due to other wifi devices used on site; when there are multiple video sources that want to access wirelessly, it cannot be switched freely; WHDI and wifi limit the bandwidth, 4K / The 8K video source cannot be transmitted through a wireless data channel
