| Smart home to residential as a platform, the use of network communications technology and integrated wiring technology, and home life on the various subsystems organic combination, through management, so that home life more comfortable, safe. Compared with ordinary household, smart home not only of the traditional functions of living, but also from the passive static structural change as a dynamic tool, provides a comprehensive range of information exchange function, helps the residence and the outside to maintain smooth exchange of information to help people effectively arrange time, enhance the security of home life, or even for a variety of energy cost savings.This paper introduces a new type of smart home control system, through the programming of the system, details the design of this principle, functions and features. In the design, by the introduction of the real-time clock chip PCF8563, the system runs simultaneously with people's lives, meanwhile, the introduction of LCD chips integrating simplified Chinese character, enhancing the readability of system procedures and making human-computer interface more human. By introducing the design of wireless transmission module PT2262/PT2272, will host systems and other systems of communication between the various units to achieve a completely wireless; Also through specific modalities set PT2262 wireless modules and PT2272 communication between the encoding, the system would be highly intelligent: on the one hand, the signal acquisition and the control units in system forms a one-to-one relationship. That is, the family will have the events of the corresponding control unit to deal with. On the other hand, theoretically the number of signal acquisition will be unlimited. It is that in theory the system handle the number of incidents is no restrictions. And if users need to upgrade the hardware (for the new incident), it need only reference to the use of the manual can be easily completed.At the end of the papers, this stage of the system design is summed up and the system design for the next step is decrypted. |
