IOT_based Smart Home System Technologies And Their Implementation

The rise and development of Internet technology, has changed the way we work and ourway of life gradually. It requires not only office automaton, intelligence, but also the automationand intelligence of household life. In this context, smart home comes into being. Smart homesystem uses the computer and network communication technology connect all kinds ofhousehold facilities together thorough family networks, so as to provide more convenient andcomfortable living environment for people.This design uses Freescale MC9S08AW128as the core of the smart home control system,which has the advantage of high performance, rich interface, and good expansibility. We usewireless sensor technology as a development platform of smart home controller, the applicationof the smart home control system development can be on the platform of secondary development,so as to shorten the development cycle, and save resources.We determine the overall architecture design through the analysis of the smart home system.According to the features of smart home system and the basic functions, we analyzes the basicstructure of smart home controller, and then for each terminal has carried on the detailed design.Finally we use the wireless touch intelligent switch, the infrared transponder, intelligentelectrical outlet, the human body infrared detector, temperature sensors, smoke detectors and soon to realize the remote monitoring of family, and master the safety of their families at anywhereand anytime. It is also convenient for the user to understand and grasp housing situation in theshortest possible time.
