Design And Implementation Of Smart Home System Based On Zigbee Wireless Technology

In today's rapid economic development,people use Internet information technology,automatic control technology and sensing technology to create intelligent living conditions,and continuously improve and enhance living environment and living conditions.Smart home integrates control objects such as household appliances and home appliances,and perceives the running status of household equipment through smart terminal equipment,controls various parameters parameters in the running process,and creates an intelligent,safe,convenient and comfortable home environment.At present,the smart home lacks substantial content and unified standard,with narrow coverage.In particular,there are many drawbacks in the way of wired control,and product interactivity and experience are poor.Therefore,this paper proposes to develop smart home system based on ZigBee wireless technology,which has very important application value.The research of this paper firstly analyzes the existing problems in the development of smart home,analyzes the current research situation at home and abroad,and points out the purpose and significance of the research.Then it discusses the core technologies used in the smart home development process,including ZigBee technology,CC2530 development board and sensor technology and so on.This paper analyzes the feasibility of system construction from different aspects such as technology,economy and operability,determines the basic requirements and characteristics of the system,and provides constructive solutions.The functional structure and workflow are designed with modular design ideas,the monitoring objects of the system is defined,and the functional requirements are proposed.This paper focuses on the ZigBee wireless network,designs the hardware and software parts of the ZigBee coordinator and the ZigBee terminal nodes,including circuits,communication protocols,control boards,upper computer and various sensors.The ZigBee wireless network is used to establish the home interior network system,and realizes the application of the ZigBee network in the smart home system.By testing the software and hardware of the system,it is confirmed that the system can run safely,reliably and stably.The smart home system based on ZigBee wireless technology studied in this paper is of great significance for improving people's quality of life.Based on the research of embedded development technology and ZigBee network technology,the smart home system designed with microprocessor chip takes the home gateway as the core,designs the ZigBee coordinator node module,and ZigBee terminal node module,and analyzes it deeply.The communication method between the home gateway of the smart home system and the home internal network was studied,so as to realize the indoor temperature and humidity,smoke and photosensitive detection system in the home.Therefore,the research and application of the system has very important application value.
