Description
Technical field
The invention belongs to brain electricity applied technical fields, are related to a kind of television set intelligently remote control system based on brain-computer interface.
Background technique
Establish between people and computer one of brain-computer interface (Brain-computer interface, BCI) exchanges
And control channel, but it is that one kind does not depend on peripheral nerve by EEG signals and these common brains outputs of musculature are logical
System that human brain and computer or other electric rooms communicate is realized in road.This technology can help those to have dyskinesia
Disabled person realize control to external environment and equipment, improve their self care ability.Studies have shown that when people is being in
The EEG signals of specific frequency can be generated under certain specific state, such as in the case where people is in sleep or fatigue state, greatly
Brain can generate a kind of EEG signals of particular frequency range, and the amplitude for the EEG signals that different people generates may be different, but frequency
Rate is identical.Based on the principle, the EEG signals under sleep or fatigue state can be collected and be used.It is existing
" the music induced hypnotic method and system based on EEG signals " patent, mainly by EEG acquisition, (EEG signal is very micro-
It is weak, it is almost flooded completely by various noises, under usual experiment condition, it needs to be used by special processing, i.e.,
BCI system will also be handled EEG signal), analysis and display platform realize the current sleep of EEG signals monitoring user
State, auditory stimulation induced hypnotic, and then alleviate the bad problem of user's sleep state.Sleep stage algorithm is namely based on sleep
In brain electric treatment, what the characteristics of EEG signals determined.The algorithm devises three parts, first is that the pretreatment of original signal；Two
It is the feature extraction algorithm of signal after noise reduction process；It is obtained point third is that carrying out processing classification to characteristic signal using SVM classifier
Phase result；But this technology is only merely to analyze the feature of sleep period EEG signals, is changed according to this analysis result
Kind sleep quality, there is no this signal characteristics that is used well.The technology of the present invention is right on the basis of analyzing EEG signal
The feature of dormant EEG signals is utilized, and the instruction of closing television is executed with this feature value；It is realized with this
The purpose of intelligent manipulation TV based on brain-computer interface technology.
In addition to this, separately there is and " studies based on portable brain-machine interface intelligent appliance control system " document, mainly
A set of intelligent appliance system using only brain electric control is devised using visual evoked potential, it not only can be to stable state vision inducting
The real-time collection analysis processing of current potential (Steady-state visual evoked potentials, SSVEP) signal, moreover it is possible to
It is converted into corresponding control command, achievees the purpose that control intelligent appliance without body language.It is big that system is broadly divided into two
Part: EEG signals real-time processor based on DSP platform and the intelligent appliance device built based on Zigbee wireless network.It adopts
With TI2000 series DSP TMS320F2812 chip, the characteristics of by DSP high speed, low-power consumption, realizes and the number of SSVEP is filtered
Wave, feature extraction and classification finally convert control command for characteristic signal to control the intelligence on wireless network node
Electric household appliance.The technology is the intelligent appliance net built using wireless network, but this has certain limitation, for being ignorant of utilizing
For the crowd of network, this is exactly a kind of inconvenience to them；And infrared technique is then different.Infrared communication technology is suitble to
It is connected in inexpensive, cross-platform, point-to-point high-speed data, especially embedded system.The main application of infrared technology: equipment
Interconnection, info gateway.File and information exchange in achievable distinct device after equipment interconnection.Info gateway is responsible for link information
Terminal and internet.Infrared communication technology is supported and is used by numerous software and hardware manufacturers in global range, at present mainstream
Software and hardware platform be provided which the support to it.Infrared technique has been widely used in setting for mobile computing and mobile communication
In standby.Remote control of smart phone application at present is divided into two classifications, one is needing network support to be controlled, and another
It then needs smart phone to support infrared emission, is controlled using infrared signal.But both modes are confined to can be normal with hand
Using remote controler and in it is awake when crowd.If people once sleeping, just can not closing television, then here it is a kind of non-
Automatic and not convenient form also creates the waste of the energy.
Therefore the dormant EEG signals of measurand are acquired based on BCI technology, after this signal is handled
It is used as the instruction of closing television, so that it may solve the problems, such as appeal；This this technology can be used to solve following two field
The problem of scape is lower met.Scene one: user is seeing while seeing TV in other things of hurrying, such as while TV opens
Mobile phone does not see TV, and such state maintains regular hour (such as half an hour), thus can be to a certain extent
Cause the waste of resource；We pass through the visual stimulator for installing a fixed frequency range on a television set, if one timing of user
The interior brain not as seeing TV would not generate the EEG signal of this frequency range, we can be believed with one be previously set
Number characteristic value instructs as corresponding closing television machine and executes the instruction.Scene two: if people can not just close once falling asleep
TV, then also creating the waste of the energy here it is a kind of nonautomatic and not convenient form.Therefore it is based on BCI technology
Dormant EEG signals are acquired, are used as the instruction of closing television after this signal is handled.This scene
Closing television scheme is most important be exactly spontaneous brain electricity signal analysis, wavelet transformation has good Time-Frequency Localization characteristic,
The detection to signal transient ingredient can be achieved, and its each frequency segment components can be handled, it is extractable to obtain sleep cerebral electricity letter
The varying information of number rhythm and pace of moving things.Our brain is not generating brain wave all the time.This is some spontaneous rhythmic neuroelectricities
Activity, frequency variation range can be divided into four wave bands, i.e. δ (1-3Hz), θ (4-7Hz), α between 1-30 times per second
(8-13Hz), β (14-30Hz).
The statement of three classes wave
It, can be according to the waveform difference occurred under different conditions and corresponding frequency according to the characteristic of these eeg signals
Rate difference is acquired and utilizes, only signal of the analysis in sleep state, and such data will not mix will not be especially more.
When system detection to this frequency range signal and send the signal to EEG Processing end carry out signal processing with point
Analysis, retransmits a first-level instruction to android system platform, then cell phone application is according to preset closing television machine
Second level instruction is executed automatically, achievees the purpose that TV is automatically closed with this.This technology has been not only suitable for movement
The crowd of obstacle is also suitable for all other men group.
Summary of the invention
In view of this, the purpose of the present invention is to provide a kind of television set intelligently remote control system based on brain-computer interface, utilizes
