Design And Research Of Intelligent Home System Based On ZigBee And Speech Recognition

At present,China's social development has entered the third decade of the 21 st century.Science and technology are developing with each passing day.Internet technology is developing towards the direction of big data and artificial intelligence.In view of the current situation of complex operation,high cost and inconsistent standard of smart home equipment,this paper analyzes and compares the advantages and disadvantages of the mainstream smart home equipment in the domestic market,and proposes a simple and comfortable smart home system.First of all,according to the functional requirements needed for the design,determines the ZigBee wireless network technology based overall scheme,can realize collection and analysis of the overall index family indoor environment,to reform the traditional intelligent home appliance equipment for the control of air conditioning,water heater,TV and other equipment,supplemented by voice recognition function,through the user's voice commands,after system analysis,treatment with ZigBee network passed to terminal equipment,in order to realize the control of the equipment.Secondly,the Arduino UNO development board is determined as the main control unit for the analysis and processing of control instructions and environmental data.The wireless network adopts ZigBee wireless networking technology to design software and hardware for the network coordinator,child nodes and various sensor modules.According to the characteristics of intelligent home system,a power management module with automatic switching circuit is designed.Based on OneNET cloud platform,ELF2530 gateway module is used to realize the transmission function of home Intranet and Internet,and the indoor environment value can be checked in real time on terminal devices such as computers andmobile phones.The speech recognition module realizes the control requirements by collecting the user's voice commands,through preprocessing,speech feature extraction and pattern matching,and finally through the main control unit to the terminal node.Finally,the experiment proves that the system has achieved the set design goal.The intelligent home system designed in this paper not only realizes the basic service function,but also realizes the design concept of low cost,low power consumption,easy operation,safety and reliability.It can make users experience the comfort brought by technology while obtaining convenience,and meet people's requirements for smart home system.
