Design And Implementationof Smart Home Monitoring System Based On Wireless Sensor Network

Along with the advent of network and digital intelligent society and the rapid development of new technology,such as high performance computing and Internet of things etc.,so it is imperative to make SmartHome into a truly stage of comprehensive implementation.SmartHome is a perfect combination of Internet information technology with traditional home industry.The various subsystems about home life is unified managed by SmartHome with the involvement of all kinds of new type sensor,and it can make life more comfortable,efficient and intelligent.What's more,with the rapid popularity of smart phone,mobile communication technology,big data and cloud technology,the application of SmartHome can cover more fully and reach a new height in home appliances,wireless remote control,environment detection and control and so on.SmartHome monitoring system based on wireless sensor network is studied in this paper.The SmartHome is taken as the research object,the actual needs of enterprise's R & D is taken into account through the full investigation of enterprise,then the environmental parameters that is required to be monitored are determined,and application of sensor technology for intelligent collection of monitoring data is studied.A solution of remote monitoring system about SmartHome based on wireless sensor network is put forward by the analysis of wireless sensor network technology and wireless communication technology.A set of perfect remote monitoring system about SmartHome is designed through the use of mobile terminal platform.Then the functions concerning basic monitoring,automatic adjustment,alarm and control of electrical equipment are achieved.So the remote control for household equipment is realized when reliable and comprehensive information of home environment is provided for home users.The key technologies of wireless sensor network for remote monitoring system about SmartHome is researched in this paper,a thorough research of intelligent data acquisition and wireless communication is done,and after completing the selection of sensor effectively and establishing a ZigBee network which can make these nodes together,a SmallHome LAN(local area network)is formed through sampling test and error comparison;a set of communication protocols is defined which has a communication function to communicate data based on the Modbus protocol,and it improves the flexibility of ZigBee wireless transmission;the effective processing and security encryption of perception layer data can ensure the reliability and safety of system;a real-time data acquisition is achieved by using multi-threaded serial communication to obtain monitoring data and building a system service platform;the client application is developed by using Ajax and WebService technology to realize the basic information management of system and adopting WebSocket HTML5 full duplex communication technology to achieve real-time interaction of Monitoring information.Finally,the achievement of this research is mapped out and tested in the actual field to verify the application of SmartHome monitoring system,and the basic functions of SmartHome is realized by the SmartHome monitoring system in this paper.The unique advantages in performance,cost,versatility and scalability of this system is of great significance to the research and exploration of SmartHome monitoring system based on wireless sensor network.
