Application And Rearch Of The Embeded Control System

Recently, the application of Internet on MCU becomes the most important part in IT. With the development of MCU and the accuracy of application, it's necessary to divide program into many important task respectively. It distributes CPU time and system resource in each task efficiently, at the same time;we must realize real-time functionality and reliability of system. Operartion System (RTOS) Kernel, which shortens the empolder period of product and enhances productive efficiency, solves the problem, however, it also supplys the possibility of the connection between MCU and Internet.The thesis describes the general development Embedded System and RTOS. And designs the application of the embedded system UC/OS-Ⅱ.In the following, the transplant of UC/OS-Ⅱ on enhanced 8051 compatible microcontroller W78E516B is described in detail. This mentioned OS is the base of realization of multi-task/user support on the embedded TCP/IP protocol stack.The next part introduces systematic design and realization of Ethernet scheme of UC/OS-II in detail. Firstly, the realization of the control module of Ehternet interface and network card is introduced. And then embedded TCP/IP protocol stack uIP is introduced, mainly including a detailed analysis of some standard Internet protocols like Ethernet, ARP, IP, TCP and ICMP. Finally, the realization of Net interface design is given in RTOS.On the base of research of the application of UC/OS-Ⅱ, Hypertext transfer protocol HTTP is described in detail, and a method to realize Embedded WEB Server in SCM system is given. And then the application of data collection is introduced in detail. The hardware design and realized scheme of Server/Client software is given. And the last of this part introduces the application of USB in Embedded RTOS, including the design of its software and hardware.Through the debug, it has succeeded.
