Internet Of Things Smart Home Control System Based On ZigBee And IOS

As the high rise of the product of the Internet of things, Smart home is gradually affect our lives. Intelligent household not only have the the basic functions of the traditional household products,but also incorporates a variety of related communication control technologies. Smart home allows users to manage household intelligent equipment more easily, brings better comfort to the user’s family life.This paper have completed the system’s hardware design based on ZigBee communication and the iOS client application development based on Xcode development platform. At the same time this system control functions have been analyzed, the key code of this system network performance was tested. Finally this paper have completed the main hardware part and software part of the smart home control system, and has met the actual demand of the project. In this control system design, the method of the UDP packet radio is used, implements the intelligent gateway information automatically, the setting is adopted to realize the intelligent household terminal customization, improve the user’s effect of this system.This paper has mainly completed the following work:1) The functionality and performance of the smart home system was studied, the overall architecture of this system was given and the relationship between each function module framework, and on the analysis of ZigBee signal characteristics, CC2530 chip performance, the iOS operating system application development advantages and characteristics on the basis of xib view, determined the design scheme of the system and each part of communication system.2) Completed this system node hardware circuit design, the key to complete the control software design and software design of communication. This paper completed node hardware design, including the design of center node, the routing node and the end node design. Based on i OS mobile, client control software design was completed, including system management control, switch control, light, security control, scene control, timing control analysis and design, among them, the system management control to realize the control and management of the whole system, scenes and timing control to realize the personalized control of smart home terminal. This paper completed communication software design, including the design of the Socket communication and ZigBee communication design.3) This paper implemented the iOS operating system based on ZigBee signal intelligent home control system, including system management, the switch control, light control, security control, scene control, timing control, Socket communication and ZigBee node communication and other several aspects. Control function of this system at the same time to realize the key code was analyzed. The simulation results of this system were analyzed. And the network performance of this system from two angles of communication distance and time were tested and analyzed.
