LED Panel Control System Application Research Based On Embedded Ethernet

LED panel system gain rapid development in the design, manufacture and application from nineties ages. It went through from single color and two color to image LED panel. Now true color panel has come true. During the development course, it obtains quite great progress in parts capability(super high bright LED panel and blue LED) and systemn form(computerized all dynamic display system).Compared with other flat display, LED panel has many special feature such as high reliability, long age, high performance, low cost, and more important high acclimatization. Moreover with the technique of all color panel perfected increased, LED panel is widely used in many place.The paper's research object is LED panel asynchronous control system. Firstly, the thesis analyze the existing problems via the sale of LED panel asynchronous control system in the market. Then giving out the new solution of data transmission using ARM9 processor AT91RM9200 and DM9161E as system core. Particularly introducing the hardware design of embedded system and the problem which must be concerned. Following paragraph talk about the software design based on embedded Linux, from Bootloader, porting system, network device design to application about UDP and TCP transmission via BSD socket programming. By the same time, the thesis gives out another software solution based on RTOS uC/OS-II and uC/TCP-IP. The last paragraph introduces the development of network for example IPv6, ultra speed Ethernet and also fiber communication.
