Study On Automation Technology Of Smart Homes

Intelligent Building is a .new comprehensive intercross subject, it stands for the latest high-tech product in architecture industry, and it has flourished all over the world as the growing mainstream on 21st century. Presently, with the prevalence of computer and the development of information industry, the concept of "Intelligentize" was introduced into home. Based on the entire Smart Home system, this paper studied the sampling and processing of alarming signal in security system. All includes:Establishment of integrated Smart Home system. The Smart Home system consists of two main parts梐utomation system and management system. This paper discusses the basic elements of security system梙ome controller and monitor program.Hardware circuits to sampling alarming signal in security system. By comparing and choosing the configuration of signal-sampling system, the input channel is designed which including the A/D sampling and converting circuits and the real time clock circuits. This paper also designed the assistant circuits such as reset circuits, watchdog circuits.Communicative interface in security system for long-distance monitor. The interface communicates with up-computer by special embedded modem. To integrate the local single chip and the modem, the asynchronous communicative adapter was added into the system.Monitoring program in up-computer. This thesis developed the program to input and dispose the alarming signal by means of Delphi language, which has ability to deal with high-effective database and network. This program has functional parts of serial port disposal, modem communication, database operation and so on. The communicativeprotocol was also used in low-voltage electric power system.DSP applies in Smart Home. Though reading a mass of documents and references, this paper brings forward the idea that DSP has advantages in Smart Home's future development.
