Research On The Control System Of Intelligent Equipment Based On Embedded Internet Technology

Embedded system is the hardware and software system, which has been embedded in the application of product and engineering, and is cored with mcu . The embedded system, which came from the combination of embedded sytem and Internet.,has become a new technology with the development of computer and network. It buildups the ability of connecting Internet through the embedded system. It bring that emmbedded system , which is cored with low -costed mcu ,directly connects Internet without PC.This thesis applys embedded Internet to intelligent home equipment. With Internet developing to home equipment, intelligent information products have came in home, and become a fashion. When intelligent home control system connects all the equipment through home bus, it will build a more powerful and more intelligent modern home system.This thesis designed and realized a intelligent home control system cored with 8bit mcu p89c51rd2. It has the ethernet interfere of connecting Internet and the interfere of connecting other home equipment through CAN bus. The ethernet interfere is realized by the ethernet controlling chip Rtl8019as, and the CAN interfere is realized by the CAN controlling chip sjalOOO and receiver controlling chip pca82c250. In the thesis, both interferes are introduced detailed.If the embedded system can connect the Internet, it not only has the physical interfere but also the TCP/IP protocol. In the thesis, TCP/IP protocol are introduced detailed. We also simplified the protocol according the character of the embedded system and realized a small TCP/IP protocol fitted to embedded system.We also designed some accessional software to enforce the function of the system.In the last of the thesis we tested the whole system in simulated condition and got a satisfied effect.
