Abstract. The main purpose of this thesis is to introduce an intelligent home control system which is based on MCU(EM78F668N), the PC(personal computer), wireless transceiver module FHL0611 as the core, to control the external temperature sensors, humidity sensors, light sensor and solar heating system. Thus the system achieves the automatic control of indoor home environment and use a wireless terminal on the indoor home of the remote control. This article also gives the device hardware and software design and implementation. Keywords: EM78F668N, Intelligent control, Indoor environment, Energy conservation.
1 Introduction Enters for the 21st century, the human society has already entered brand-new information age. Along with the social economic development, people living standard improving, the people to their own living environment requirement becomes higher and higher. Meanwhile, because of the community's progress and future development of human civilization and the general concern, People's energy-saving, green, environmental protection has become a subject of the pursuit of a more conscious action. In modern society, people pursue the life that with perfect quality, personalized and automated. The humane and intelligent in intelligent control technology of morden home required to make smart home electronics products have been widely used. It not only optimizes the people's lifestyle and living environment, but also convenient people to effectively arrange a time and save a variety of energy. It achieve the appliances, lighting, curtain control and burglar alarm, remote control. Smart home manufacturers are mainly composed of traditional residential quarters smart system manufactures, for now mostly smart home systems are sub-systems of residential quarters smart systems, especially turning from security system and visual intercom system. Those systems are not fit for the single individuals, so it is a valuable subject that develops a low-cost temperature controlling device. we design a morden home which is based on solar heating and intelligent home control system as the core. And the morden home can meet the modern pursuit of comfort, energy saving, environmental protection, and convenient H.

concept. Adopting EM78F668N chip is an attempt for us to realize controlling of comfortable living environment.
2 Design of Hardware System This system is based on micro controller EM78F668N to control modules, as shown in figure 1: sensor module, LED module, the power modules, all kinds of indoor appliances, electric curtains module, solar energy heating module, wireless communication module, etc. EM78F668N is the core of intelligent household system. The system mainly includes the following functions: (1) When nobody in the home cut off all the home appliance 220 V power source, which not only eliminates all kinds of electric standby power consumption, but
