碩士 === 國立雲林科技大學 === 電子與資訊工程研究所 === 94 === The application of Internet has become not only having education value but also having business value such as multimedia transmission, due to the emergence and spring up of Internet and ADSL etc. These reasons induce that all of application will be integrated in IP-based networks. Based on the platform of IP-network, the communication product which has the ability to carry data, voice, control, and video information, will dominate the future markets. The major problem in the automatic industry control system is that how to design a control platform which can support the control conditions of long distance, wide range, and high resolution. Up to now, the most of control platform are focus on the interface of RS-232 or RS-485 which also have the limitation of transmission speed, control range, and wire problem. In this thesis, based on the client/server model we target on the design and implementation a control platform which can be applied to the large coverage control environment. We use the control platform to the light control system. The server side is realized by the personal computer. According to the music play the server sends different control commands to the client module via Ethernet interface. In the client side, based on the 8-bit 8051 micro controller, we integrate the Ethernet interface, communication protocols, and I/O control for light to realize an embedded network control platform which follows the server command to control the on/off of lights. In this thesis, we develop a control platform which has the properties of simple, low cost, large coverage range, and high transmission speed. The control platform can applied to the automatic industry control environment.
