基于4G-LTE的脱机LED控制系统的设计
Design of off-line led control system based on 4G-LTE
摘要
Abstract
On the market,the off-line LED display currently used to control the display content mainly by wired.With the rapid development of mobile communication technology,4G is beginning to enter the popular stage.Compared with the traditional wired communication mode,4G technology isn' t bound by the place and has obvious advantages in engineering cost,environment adaptability,network expansion,equipment maintenance and so on.In order to solve the problem that wired LED display is not installed because of the geographical location,communication distance and the installation mode, off-line LED control system based on 4G-LTE is designed.The system is designed with the core of i.MX6Q micro controller,wireless communication module of 4G-LTE,and scanning control module of FPGA chip,and achieves a new off-line control system structure that based on ARM + FPGA + 4G, and matches PC software based on TCP /IP network communication protocol.The off-line control sys-tem can achieve wireless transmission of high-quality images and video,and support 256 full-color LED gray-scale display screens of graphics through the 4G network.After testing,the system can run stably and effectively,and have higher practicability and transmission.关键词
