| With the rapid development of computer technology,intelligent home gradually replaces the ordinary traditional home,so that people’s lives become more comfortable and intelligent.At the same time,the concept of whole-house intelligence has also been proposed,but there are some problems such as high price,possible invasion of user privacy and difficulty in achieving equipment standardization.Through the research on the development and current situation of smart home,this paper designs and implements a localized whole house intelligent system based on Raspberry PI,which can solve the above pain points to a certain extent.Firstly,the physical layer equipment of the whole house intelligent system is designed and transformed.It mainly includes a sensor network and a number of other devices that can be controlled.The sensor network and some devices with simple control instructions adopt CC2530 chip,and Zig Bee technology is used as the underlying network structure for design and transformation.The equipment with complex control instructions or large amount of data transmission is modified with ESP8266 chip and WIFI access system.Secondly,a series of whole-house intelligent system services are designed and implemented.These include speech recognition,speech synthesis,Rasa dialogue robot,Home Assistant,and IOTManager services.The services work together to provide users with home environment monitoring and home equipment control functions.In addition,Docker technology is applied for containerized deployment in order to make it easier to maintain and upgrade each service.Thirdly,a mobile APP is developed using Android technology and voiceprint recognition technology.It is used to receive the user’s voice input and interact with the whole house intelligent system service after successful voiceprint recognition.Finally,this paper designed and implemented a whole house smart home scene mode of elderly care.A practical application scenario of smart home system is described. |
