Abstract

The invention discloses a wirelessly controlled LED display screen information distribution system, which comprises a central management computer, an Internet, a GPRS, a control card, and an LED display screen. The invention adopts the following technical scheme that: a control card is arranged on each LED display screen; the information is distributed on control cards of the LED display screens distributed in various places by using the conventional wireless internet system platform and a central management computer in the wireless transmission mode through the Internet and GPRS system; and the control cards control respective LED display screens to display and distribute. Therefore, the defects of difficult remote distribution and arrangement and resource waste are overcome. The wireless control LED display screen information distribution system provided by the invention realizes real-time servo work of a plurality of LED display screens by using one computer in the wireless transmission mode. Therefore, the LED display screens can be remotely arranged in a scattering way, and can adjust and change information distribution contents in real time and save the resources.

Description

technical field [0001] The present invention relates to the release technology of LED display screen information, specifically refers to a wireless control LED display screen information release that uses the existing wireless Internet access platform to perform real-time adjustment and replacement control of the information content displayed and released on the LED display screen through wireless transmission system. Background technique [0002] LED display is to display graphic and video information by controlling the on and off of the semiconductor light-emitting diode array; it has been widely used in stations, docks, airports, shopping malls, hospitals, hotels, banks, markets, schools, factories and mines, cultural and sports Venues, municipal public service places. [0003] The information release of the LED display screen in the prior art adopts a wired connection with a computer for transmission. Since the wired connection transmission mode is limited by the transm...
