The Design Of Intelligent House System Based On The Brain-computer Interface

With the unbelievable growth of economy and fast step of science and technology,people's requirements for residential is no longer a simple shelter.First,it should be strong,followed by beauty and now healthy is to be concerned,so is safety and convenience.This is the reason why intelligent buildings become popular all over the world.There are many systems in smart buildings,for example lighting system,air conditioning system,water supply system,integrated wiring system and fire automation system.It is also essential for some smaller intelligent home to be equipped with lighting and air conditioning systems.So in the basement of the wireless network control,intelligent information management system of home automation needs more in-depth study.Smart home has two different meanings.The first one is defined in the definition of "smart home" system,or we usually refer to the meaning of a residential environment.It is not only a smart system in buildings,but also an intelligent project implemented in a residential environment among multiple buildings.The second refers to the system products produced by the smart home manufacturers and meet for the main functions of the integration in smart home system.Such products should be completed by means of integrated installation,so all this system products should be a complete service process including hardware products,software products,integration and installation services,and after-sales service.The market of smart home in our country is in a period of rapid development and the future demand will be more and more strong.The traditional smart home is poor on integration performance.Because the degree of intelligence is not so high,the purpose of living more comfortable did not come true,so did the need for a better life.For some people who do not understand the use of intelligent home automation or the entire appliance equipment and someone who have unhealthy body and cannot be independent to control different equipment,the traditional system will not make people's life more convenient.Therefor there are so many places which need to be improved.In this paper,these problems are put forward and will be solved on my own opinion.There are some works I did before:1)First,this paper list some relevant knowledge about the smart home,brain computer interface and wireless sensor networks.Understanding of the operating process of each system set up the foundation for the following system design;2)This paper has simplified the whole system in the smart home,leaving behind the parts for daily life,such as lighting and air conditioning systems,of course,as well as security systems.After sorting out all these sensor nodes in systems,which are used for information collection and transmission,it is necessary to set up a wireless sensor network.On the one hand,it is useful for data collection,storage and processing of data.On the other hand,analysis results will be sent to the managers;3)The processing for collecting and dealing with the EEG signals under different conditions of human imagination is necessary before some features have been extracted out.And then the data is converted to a digital signal through the wireless network transmission from one node to another node(i.e.the coordinator),and then transmitted to the control system.The control center will compare the characteristics of real-time data with the EEG signal which has been stored readily before,and then send the control command to control equipment for achieving various functions;4)In the end,this paper presents the integration of whole system.Both the biological signals and environmental physical signals are included in the category of sensor signal acquisition.And then the researchers can make the judgment of human's thought or the parameters of surrounding environment through the signal so that the system will response in a correct way and give the control to some outside equipment.
