AbstractHome Abstract Home centralized control system links all the electrical appliances in a family by the use of embedded technology,home appliance control criterion and the protocol of communication．It provides a more comfortable，segure and convenient living environment with the real-time and intelligent control of the appliances． This paper,which has all actual project background，includes the intelligent home’S derivation,development and achievements in recent years．We observed that the tools of mobile communications were commonplaces nOW and the traditional appliances still played the main role at home．So according to our analysis and demonstration On the related technology,we designed the construction of the system， and presented a scheme that can implement interconnection in a house like a network． In this scheme，it used several technologies including RS·485 bus technology, mobile communication technology and infrared communication technology．Here， we presented the overall design of our intelligent home control systems that based Oil wireless communication．Parts of the system which have been realized are shown as follow： 1．Participated in instituting the communication protocol of the system，which is based on the characteristic of data transmission in wireless communication theory and the need of this home centralized control system． 2．Designed the wireless transceiver circuit’and its peripheral circuit after the study of the theory of the wireless communication and the pfindple of nRF2401 chip． According to home appliances control protocol 1 wrote the code of wireless transmission and receiving program with c，and implemented communication through the home appliances control system． 3．Designed the LeD disphying circuit．The LeD can display types and numbers of the appliances that user is controlling through TN positive display． 4-Designed the matrix keyboard circuit．Used interrupted mechanism to control the matrix keyboard SO as to SaVe power． 5．By analyzing t
