The Research And Development Of Intelligent Home Monitoring System Bsased On Arm And Zigbee

With the development of Internet of Things technology and intelligent equipment,people dissatisfy with their living environment which can only allow us to live. The realization of digital and network in living environment is an inevitable trend.Intelligent Home Furnishing can provide a modern way of life, a more intelligent and orderly for human beings, which is an inevitable trend of the future residential mode.In response to this circumstance, this paper develops a intelligent home monitoring system based on AMR and Zig Bee. The center of the system is an intelligent gateway which is made up of ARM and Zig Bee coordinator. It provides the internal and external network services between the Zig Bee Network and Internet. And the gateway also exchanges data with Zig Bee end device, network server and Android application.An application product is developed by Qt on intelligent gateway, it is controlled conveniently.Compared with the traditional Home Furnishing intelligent system, a historical data storage function is added to the system on the basis of realizing the basic function of the intelligent home monitoring system. These data make it possible to analyze by using large data method in the future. By using the Libevent technology, a high performance network server which is used to store the historical data of the home control system is added to the system to realize this function. The system also adds temporary data storage and temporary data synchronization function to deal with different network environment. As the response to the phenomena which hackers leak database of large Internet company a more effective method was taking to encrypt the user information especially the password on the basic of MD5 by slowing encryption process and adding salt.This paper firstly describes the background and significance of the subject,analyzes the development status of domestic and international smart home, and then introduces the related technologies to be used in this system. After that a cross compiler environment is built for the host computer and target machine. Then the whole system architecture is described in two aspects of hardware and software.According to the hardware architecture there are four main parts: the Zig Bee end device, intelligent gateway, network server and android application. The design,implementation, program design and implementation details of every part is described in detail to realize the system.A smart home monitoring system which has high promotion application value with friendly interface, simple operation, high security and comprehensive function is developed after practical operation.
