Research Of Smart Home Environmental Monitoring Systerms Based On Networking Technology

With the increasing of the requirement of quality in life,people have increasingly strong demand about the intelligent household environment.So the automation of environmental information and electrical equipment monitoring has become the inevitable trend of intelligent building industry development.In recent years,along with the fast and steady development of our country economy,people are paying more and more attention to the environmental problems,and especially the building indoor environment.The environment quality of building indoor has a direct impact for people's health and work efficiency.Therefore,it is very important to design a system which can monitoring and adjusting building indoor environment.based on this starting point,this paper study the intelligent household environment monitoring system based on Internet of things technology,and design a smart home environment monitoring system based on ZigBee wireless sensor network.First,this paper expounds the characteristics and developing status of intelligent household environment monitoring system,introduces the relevant technology of the Internet of things,compared the several typical wireless communication technology,and introduces the characteristics of the ZigBee wireless network communication technology in detail,it is very suitable for smart home information transmission,it can fully satisfy the information communication between the sensor and electric equipment.And then,this thesis designs a intelligent household environment monitoring system based on Internet of things of overall scheme,determine the structure and function of the system,using Zigbee technology can make the building environment and the control equipment be the wireless network system,based on ARM embedded gateway information control center,the system will be according to the environment of sensor gain parameters for switch control of the corresponding electrical equipment,make the environmental parameters to achieve the set range.And the system is mainly the design of the hardware and software in detail,including environmental information acquisition circuit,ZigBee network nodes,the design of the intelligent home gateway and intelligent switch,etc.In the framework of the intelligent household environment monitoring system,combined with intelligent control theory,the particle swarm optimization(PSO)optimized support vector machine(SVM)classifier is applied to the system,the system has more intelligent control strategy,the Matlab simulation data with actual cases,and the results show that PSO-SVM classifier can make the system control decisions more accurately,and help improve the reliability of the system.Finally,this paper uses UML object-oriented design idea to design the upper machine of the system and analysis the requirement of the system,software of StarUML is used to design,and introduced the main use case diagram,class diagram and sequence diagram,user interface design is realized by using Java.Also on the part of the system function test,the test results show that the system can implement environmental information acquisition and wireless equipment automatic control functions,to achieve the desired effect.This system is stable and reliable,its operation is convenient,and has a good performance of extensible.This system has certain market application prospect and theoretical significance.
