Research And Realization Of Smart Home System In Advanced District

The thesis begins with studying the development condition of domestic and international Smart Home System, and introduces the present solution by detailed analyzing and comparing the development all kinds of technologies. Combining the actual circumstance of the our country, based on the design principle of "humanist", the thesis designs and realizes a Distribute Smart Home Control System .The present Smart Home System mostly with single-item functions and assisted a handful of related functions, can'tembody the superiority of intelligence, or assist life. Aims at the real meaning of intelligence of the complicated environment, the thesis designs to adopt ATmega8 singlechip as the controlling center, applies the existing computer technology, sensor technology, and combine field bus technology, architecture technology and mechanism design technology, and composes an intelligent network system to realize the function of adjusting indoor environment, controlling and supervising home appliancese and managingindoor related devices intelligently.The Distributed Smart Home System applies RS-485 communication protocol whose frame is simple, and uses mufti-machine correspondence technique carried out the information commutation of the virtual host and each extension, overcoming the weak dependability of depending on one host, and guarantees the vivid stability of the whole system circulate. Based on designning the home bus, realizes to sharethe residence information and control all the equipmentses effectively.In addition, the paper designs a few special features functions equip,such as saving waterinstallment, the warm water maintenance installment, temperature and humidity system can guarantee the indoor comfortable moderation, ecosystem system indoor can guarantee the air indoor fresh, the safety guard against theft system can guarantee without the artificial constitution and control the solution to defend or establish to defend by identifying automatically.And other humanized function also manifestes out of the ordinary and the intellectualized characteristic of the Smart Home System, and shows out the character of comfort, saving energy, economy, emerges the basic characteristic of intelligence of the system completely.Now the system is reliable in communication, simple in operating, friendly in man-machine interface,high ratio of performance to price, easy to be maintained and worhy to be recommended.At last, the thesis also combines to experiment to discuss the step and the design principles of Smart Home, at the same time argued the development of present condition and the application in future, emphasized, elaborated and initiated the design principle of "humanist".
