Design And Implementation Of Smart Home Environment Monitoring System Based On ZigBee

In 2018,the World Conference on the Internet of Things was held under the background of the development of economy and the wisdom of mankind towards the interconnection of all things.It is hoped that the Conference will promote the development of the new economy of China and the Internet of Things and"build a community of human destiny"with the Internet of Things.With the gradual saturation of communication between people's networks,the operators of traditional communications at home and abroad are looking for new growth space.However,the Internet of Things has a huge market space,which provides a very good opportunity for the development of traditional communication operators.At present,the Internet of Things has become a hotspot of development.Aiming at the compatibility of client side,relatively single function,high power consumption of sensor network and insufificient remote real-time monitoring ability of monitoring objective environment,an intelligent home environment monitoring system based on ZigBee is designed and implemented by combining an improved WSN ad hoc network routing algorithm.The main work is as follows:Firstly,the strengths and weaknesses of distinct wireless communication schemes like LoRa,NB-IOT and ZigBee are analyzed,and a framework of intelligent home environment monitoring system based on ZigBee is constructed.Secondly,the hardware and software design of ZigBee module based on CC2530 is completed according to the system requirement analysis environment data acquisition and client real-time intelligent monitoring scheme,and ZigBee Ad-hoc Networks is built based on Z-Stack of Texas Instruments Company,which meets the actual-time monitoring of environmental variables like fire,temperature and humidity,human body infrared,and simple home appliances like relays and fans Control.Thirdly,the design of embedded control platform,server and client is completed.Qt-based applications are designed on Linux and Linux system is transplanted.A client of remote login compatible with all kinds of operating systems is compiled to provide users with more convenient Human-Machine Interaction.Fourthly,Taking up with the energy expenditure-related problems of intelligent home environment monitoring system based on ZigBee,a suitable routing algorithm of ad hoc network is proposed.By considering the address distribution of each node module,the integrity of WSN is guaranteed,the energy consumption of WSN is balanced,the life cycle of the network is prolonged,and the performance is evaluated and verified by simulation tools.Finally,the overall monitoring system tests the ARM platform functionality and indicators.The experimental results show that some of them achieve the expected functions and maintain a relatively stable function.In addition,after adding the corresponding ad hoc network algorithm,the system's underlying delay,packet loss rate,and life cycle-related indicators are tested and compared with the results.
