Design And Implementation Of The Embedded Intelligent Household Control Terminal

Informationization and the application of intelligent electronic technology in the household brought safe, comfortable, individuation, intelligent household life for people. The rise of homehold intelligence has become a inevitable trend. Intelligent household platform on residential, integrates wiring technology, network communication technology and intelligent electronic technology, safety technology to one,construct efficient, safe, environmental protection family affairs management system, improve the quality of household life, greatly promote the harmonious of household life. Intelligent household system mainly includes family security systems, family communications systems, household automation systems. Household control terminals is the core of intelligent household system(contains the function of household gateway). And through the use of network technology, it implements the interactive information internally. By means of man-machine interface, the users can easily to control the domestic equipment.Based on the comparative study of the development in intelligent household at home and abroad, combining household control and management requirements, discussed the structure, function and characteristic of a intelligent household control terminal, which used ColdFire52235 as the main controller, by adopting the embedded Ethernet technology, designed a embedded intelligent household control terminal. the project work completed the following job:①Based on low cost built a intelligent household system framework. Its control terminals not only can achieve to control internal lights and equipment of family,but aslo can ealize the protocol conversion between familie subnet with external network.②Based on the embedded Ethernet technology research, completed the implementation and application of an embedded TCP/IP protocol in the main control chip.③Design a protocol conversion module between familie subnet with external network, which was build by RS485, through the family gateway, the internal subnet can communicate with Ethernet. The household control terminal realized the function of household gateway.④Designed a set of embedded intelligent household control terminal, built a intelligent household control hardware and software platform, gives out the terminal hardware structure and software realization scheme. Test data showed that the household gateway performance stable and can meet the household control and management requirements, the design is reasonable and feasible.
