[Abstract]:With the rise and development of the Internet of things, smart home appliances, as one of the nine demonstration applications of the Internet of things, have also been rapidly developed. The traditional intelligent home appliance system adopts the integrated wiring technology, which has the disadvantages of poor flexibility and difficult to install and maintain. Intelligent home appliances based on wireless sensor network (WSN) have changed the communication link from wired to wireless, which has the characteristics of strong expansibility and easy maintenance, and has been paid more and more attention in recent years. In view of the shortcomings of single control mode and unidirectionality of the existing wireless sensor network intelligent home appliance system, this paper proposes a bidirectional wireless sensor network intelligent home appliance system architecture. Two kinds of intelligent home appliances systems based on CC1100 wireless sensor network and ZigBee wireless sensor network have been designed successively which effectively solve the problem of stateless feedback of the existing intelligent home appliance system and the defect that the proprietary wireless sensor network cannot be self-organized. The main contributions and innovations are the introduction of GSM network to transform passive detection into active monitoring, the development of a new lighting control method based on ZigBee wireless sensor network, and the development of intelligent lamp head with independent intellectual property rights. The speech recognition and remote control terminals are introduced to realize the diversification of the control terminals. The intelligent home appliance system based on CC1100 wireless sensor network is designed to solve the current situation that the existing intelligent home appliance system only has one-way control stateless feedback link. The system includes two parts: the main control module and the terminal control module. The GSM network is introduced as the external control network, and the stability and reliability of the network are verified on Shenfu intelligent G-Home platform. The intelligent home appliance system based on ZigBee is designed to solve the problem that CC1100 and other proprietary wireless networks cannot be self-organized and do not have routing algorithm. The system includes home gateway, intelligent lamp head and other intelligent terminals, which work together through the upper computer interface. The location problem of intelligent terminal is solved effectively. The latter not only improves the network performance, but also introduces GPRS, voice control and other control methods. In addition, a new type of intelligent lamp head is developed to solve the power supply problem of single fire switch and the rewiring problem of zero fire switch. The system studied in this paper has the advantages of following the practical application requirements, complete function, simple operation, and has certain practical significance and wide application prospect.
