Abstract

The invention relates to network remote control, in particular to a GPRS-based remote LED panel control system. The GPRS-based remote LED panel control system comprises an upper computer control terminal, a transit server and lower computer LED panels. The upper computer control terminal is in network connection with the lower computer LED panels through the transit server. According to the GPRS-based remote LED panel control system, remote control is achieved through the intranet penetration technology and the transit server, and each LED panel can be controlled by all networked PCs; wired control and wireless remote control are both achieved; the laying cost of communication lines and the communication fault rate are reduced; the stability and timeliness of LED information transmission are enhanced; the LED panels can receive information issued by the upper computer control terminal at any time, so that the working efficiency of the LED panels is greatly improved; the remote transmission data volume of the LED panels is increased, the information is sent through a GPRS DTU, the TCP/IP network protocol is adopted, and the number of networked terminals is not limited; the remote application distance of the LED panels is extended, and the LED panels can be used at any places with GPRS network coverage without distance limitation.

Description

[0001] Technical Field The present invention relates to network remote control, especially to the field of LED display remote control. Background technique [0002] In practical application of LED display, most of them are single non-Internet of things design, which fails to realize large-scale publicity and real-time update of multi-LED display. In terms of the transmission method of LED display information, through wired transmission, an additional expenditure for line laying is required; while the existing wireless transmission has disadvantages such as low quality of long-distance communication and small amount of data sent at one time. limited. Contents of the invention [0003] This system aims at the various disadvantages and limitations of traditional LED displays, and solves these problems through a set of stable and perfect remote control system, including the realization of unified remote control of multiple LED displays, real-time update of display content, chang...
