[Abstract]:As an important application of the Internet of things, smart home is developing rapidly. In recent years, a large number of smart home enterprises have emerged in our country, and traditional home appliance enterprises have opened their own smart home model one after another. Even Samsung, Google and other companies have joined the research tide of smart home. It is of great value to study and construct a convenient, efficient and low-cost smart home system. In this paper, a smart home system based on ARM9 is designed and developed based on embedded linux technology, ZigBee technology and QT technology, which provides a comfortable, convenient and intelligent living environment for users. This paper introduces the background of smart home industry and its development at home and abroad. Then, combining with the actual situation of household appliances and other household devices, it investigates the functional needs of some users for smart home. After analyzing and discussing the possibility of realizing the system, this paper introduces the overall architecture of the intelligent home system, and designs the software and hardware scheme of the system. From a functional point of view, The system can be divided into wireless sensor network subsystem and infrared self-learning remote control subsystem. BOA server and user interaction page are the basis of realizing the function of the two subsystems. Background processors make it possible for users to access smart home systems at any time, anywhere, After the interactive page of the system is verified by the user information, the user can complete the control of the home common equipment and the equipment equipped with the remote control, as well as the acquisition of the house information. In the wireless sensor network subsystem, by studying the ZigBee wireless sensor network protocol and combining the indoor layout, the wireless sensor network suitable for the residential interior is established, and the coordinator node is set up in the network. The router node and the terminal node design the application program of each node according to the data transmission mode between the nodes, in addition, In order to facilitate the data transmission in wireless sensor networks and the identification of transmission data and the extraction of key information between nodes and BOA servers, According to the design idea of data packet in computer network, the data transmission standard of wireless sensor network subsystem is established in this paper. Infrared self-learning remote control subsystem is an infrared self-learning remote controller designed and implemented by using ARM9 technology QT technology and WEBKIT technology. The remote controller cooperates with wireless sensor network subsystem. The remote interaction between the user and most of the devices in the home at present is realized, and the control blind spot is reduced. This paper focuses on the design, compilation, transplant process and remote control method based on WEBKIT of the QT main interface of the infrared self-learning remote controller. The test results show that the infrared self-learning remote controller designed in this paper can not only centrally control but also remotely control each household appliance equipment equipped with remote control through the network. In addition, the infrared self-learning remote controller designed in this paper has the performance. Scalability and applications in smart home systems also have many unique advantages.
