The Researches And Applications Of The Wireless-Controlled Security System For Smart Home

This paper develops a kind of equipment for the home intelligent security system based on the mobile phone control. This equipment can meet people's urgent need such as timely understanding of the family security situation, real-time information processing, and effective control. Using the existing mobile phone networks, it can achieves multiple functions of the family requested safety control and warning, such as fireproofing, guarding against theft, and emergency rescue, etc. in the form of short messages. Simultaneously in the aspect of family electric intelligent control, it can also realize the intelligent management and regulation to the domestic electrical appliances, and farthest meet home users'humanization requirements through a variety of regulating means.The paper firstly discusses the development general situation of smart home at home and abroad, and according to the domestic and international developments and trends, it does researches and designs a wireless-controlled smart home security system. This intelligent warning systems uses wireless transmission technical means, overcomes the shortcomings of cable transmission technology, and using the wireless data communications module TC35 as a main device of circuit, constructs GSM communications module, serial-port communications chip MAX232 circuit design, and PT2262/2272 series declassified IC to make the matching interaction with the wireless detectors. So the system achieves the receiving and dispatching and police control of wireless data communications module, the home warning information, selective control of household appliances, realty management center's unified management, and user's decentralized control.
