Design And Implementation Of Intelligent Home System Based On Bluetooth Technology

With the progress of science and technology,the quality of life of the people is also improving,which puts forward higher requirements and standards for the home environment,especially after entering the information age,it is developing towards the direction of network,information and intelligence.Smart home is the integration of advanced information technology,electronic technology,interconnection technology and Internet of things technology in the traditional home life,connecting many modules involved in the home with the help of the Internet,so that it has a series of functions,such as automatic operation,remote control and environmental monitoring,so as to build a convenient,efficient,comfortable and intelligent modern home system.This paper first introduces the embodiment and future trend of smart home from three aspects: domestic,foreign and future.Analysis based on major short-distance wireless communication technologies,such as infrared communications,Bluetooth communications,and Finally,it is determined that the Bluetooth communication mode has not been completed.In order to prove the practicability of Bluetooth technology in this aspect,based on the research and analysis of Bluetooth communication principle,the simulation model of Bluetooth transmission voice signal is built.This paper focuses on the application of Bluetooth technology to the design of smart home system,which is mainly composed of four parts,one is Bluetooth communication part,the other is smart home control part,the third is voice control part,the fourth is environmental information collection part.When designing the hardware part,S3C6410,which has high performance-price ratio and extensive technical support,is selected as the CPU,of the core controller.The Bluetooth chip of type is used to complete the communication function between all the devices.the chip has the advantage of low energy consumption.SHT11 temperature and humidity sensor and MQ-4 smoke sensor are selected to collect the environmental information of home environment.In the design of voice command discrimination function Chip,through The wave control mode is complete.Intelligent control of prompt lamp;select LM298 motor control chip to realize automatic curtain control.The research and development of the software system involves the following related links,one is the main program part,the other is the Bluetooth function part,the third is the voice application part.In order to facilitate display and manipulation,complete and optimize human-computer interaction,with the help of The development of local graphic function window is completed.Through the test of laboratory environment and the function test of the whole machine,the smart home system developed in this paper can meet the basic demand standard of the people,can carry out intelligent analysis and disposal of its environmental information,can carry on the double control of keystroke and voice to the home equipment,the operation is simple,the function is perfect,the energy consumption is small,the cost is low,the market prospect is very considerable.
