A Research And Design Of Control System Based On Ethernet

The thesis discusses the hardware and software implementation of a Control System based on Ethernet in detail. The system with many useful features can be classified to a new generation. It is a preferential selection for the control system of next generation, because it has solved the conflicts between the increase of multimedia classroom and the lack of administrators. Furthermore, it has realized automatic management of multimedia classroom and simplified the complexity of equipment application.We have done a lot of hardware and software work to solve some crucial technical problems as follows:(1) We select proper apparatus to meet the system requirement of hardware system.(2) We program a compact TCP/IP communication protocol stack.(3) We design a friendly user interface.(4) We combine the USB, serial interface and Ethernet interface commands.(5) We design the USB firmware program.(6) We realize the design of anti-jamming. There are several innovations in the project.Firstly, we adopt an interface of Ethernet to realize remote control.Secondly, we adopt several interfaces, such as USB2.0 and UART interface, to simplify the difficulty of implementation and solve the technical problems.Thirdly, we adopt ARM7 MCU as the control core of the system, which evidently improves the whole performance of the system and reduces the cost.At last we make a conclusion to the thesis and we believe that the new control system will replace the old generation system in the future. At the same time, as a practical project, there are some valuable ideas and ways for future research.
