Embodiment Construction

[0034] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] 1. A method of loading LED display information:

[0036] A method for loading information on an LED display screen, using an intelligent terminal headphone interface to drive a pluggable external infrared transmitter module to send out infrared information, pair with an infrared receiver module and a control card with a font library to receive information, and transmit it to the LED display The screen realizes the transmission of LED display content.

[0037] see image 3 and Figure 4 , the present invention uses a dedicated APP (application software) running on the smart terminal, the dedicated APP has a man-machine interface, and uses the text input method of the smart terminal to input and display content; it also has a voice recognition function, and the operator informs the APP through voice that it needs to display Th...

Abstract

The present invention provides a method and system for loading information on an LED display screen. A pluggable external infrared transmitting module is driven through an earphone interface of an intelligent terminal to send out infrared information, and is paired with a control card with an infrared receiving module and a font library to receive information. Pass it to the LED display to realize the sending of the LED display content. The LED display control system includes an intelligent terminal, an infrared emission module, a control card and an LED display unit board; the infrared emission module adopts the frame format of the infrared remote control to realize the communication protocol of the short control frame. Compared with wired transmission, the present invention has the characteristics of strong functionality and convenient operation; compared with wireless transmission, it has the advantage of low cost. The signal transmission is carried out by designing a special control card with a font library and an infrared receiving module, which has the characteristics of reliability.

Description

technical field [0001] The invention relates to an LED display screen control method and system, in particular to an LED display screen control method and system for realizing infrared remote control through an earphone interface of an intelligent terminal. Background technique [0002] In the prior art, there are mainly two ways to load the display content of the LED display through infrared remote control: the infrared remote control baseband communication protocol and the LED serial port standard communication format, which require a special remote control keyboard to achieve, with limited functions and inconvenient operation , poor effect and high cost. For example, the methods for on-site loading of displayed content in the LED field include computer serial port, computer network port, U disk, and special keyboard infrared remote control. [0003] The LED display (screen) control system usually consists of a unit board (LED dot matrix, drive, decoding), control card an...
