The Design And Implementation Of Voice Smart Home System

Since entering the 21st century,along with the rapid development of information technology,science and technology and the improving of people' s living standard,people's pursuit of intelligent household,voice and networked trend has become increasingly obvious.Although smart home system develops slowly because of many factors,the concept of smart home system has begun to mass,intelligent household,as a major application of Internet of things era direction must be a long time in the future of hotspots in the field of intelligent control.Now with the emergence of the voice recognition technology,the voice of household intelligent control has also become popular in research of computer and communication.Meanwhile,ZigBee technology with its unique technical advantages,take it as the core of wireless smart home system become by far the most excellent smart home solutions,is currently an important direction of the development of the smart home.Based on the characteristics of the structure and function of smart home as a starting point,deeply study the working principle of embedded gateway,speech recognition,ZigBee and the sensor modules,aims to design and implement a voice smart home based on Android terminal,Web terminal system.Thesis mainly finished the following work:1)Designed a smart home system model,the model will be inside the bedroom home appliances connected into a communications network,through the sensors to collect the corresponding data,using ZigBee wireless information technology to finish each home appliance node to the embedded gateway information transmission,at the same time use the network(Internet,GSM/GPRS and 3 g/4 g,PSTN and other public network resources)to provide external access interface,system has the scalability and remote control abilities;2)The principle and application of voice recognition technology is studied,and successfully transplanted the Keda xunfei speech recognition technology,realized the function of speech precise control of smart home;3)Interacting with the smart home system was implemented Android,Web control program,the control process sequence can use wireless communication means such as bluetooth,WiFi,information for indoor home appliance,and carry on remote control,the biggest bright spot is the use of the voice of speech recognition technology to achieve the precise control of indoor home appliance function;4)Designed and completed a human-computer interaction interface which can good communication with the user's Android?Web terminal,greatly improving the voice intelligent household practicability and operability.This paper tests the smart home system the interaction with Android?Web terminal under the condition of outer net,the test results show that the Android,Web terminal control system can be very good voice control indoor and various household appliances,and has reached the requirement of design proposed in this paper.
