Description

The measurement of signal of organism and guiding device
The present invention relates to a kind of device that is used for the measurement and the guiding of signal of organism, the signal of this measurement device organism, blood pressure for example, rapid pulse, and E.E.G, one side is as the index of health, on the other hand, provide stimulation, make the signal specific of organism be directed into predetermined direction according to the signal value of measuring, more particularly, the present invention relates to a kind of its big I be convenient to the to wear measurement that is used for signal of organism of carrying and the device of guiding.
The signal of the various organisms that can be measured by people is arranged, and these signals are as learning able-bodied important parameter, for example blood pressure, rapid pulse, body temperature and E.E.G voltage.And, for the people who stands this measurement, when the signal of organism is a bad value or during in physiology or psychological undesirable value, be described value guiding favourable to the direction that presents good value to people's psychosomatic health.Therefore, had several devices to be used for the measurement and the guiding of signal of organism, the signal specific of these measurement device organisms also provides stimulus information, so that the direction of wishing on organism guiding psychology and the physiology.
Be that example more specifically describes below with the E.E.G.It is said has confidential relation between people's E.E.G and people's Physiological Psychology state.In general, be divided into four classes to it according to the frequency of E.E.G so long, promptly 1-4Hz be δ ripple, 4-8Hz is θ ripple, 8-13Hz is α ripple, what 13Hz was above is β ripple.Under normal physiological conditions, these E.E.Gs exist with admixture.When these E.E.Gs specific one when preponderating then shows following feature.
Be that the δ ripple is the E.E.G that occurs when the people sleep soundly, the θ ripple is the E.E.G that occurs down when the complete relaxation state of people, promptly ponder state or be in the E.E.G that occurs under the state that reaches after firm the falling asleep when the people is in, the α ripple is to increase energy to concentrate the E.E.G that strengthens faculty of understanding and memory, and when loosening, the people occurs, the β ripple then is the E.E.G that occurs when human brain is actively movable, i.e. the E.E.G that occurs when people's study or work.If measure above-mentioned these E.E.Gs, if and this specific E.E.G of α ripple is preponderated, the people is concentrated and increase faculty of understanding, thereby they are brought to the state that can carry out creationary research and improve work efficiency.
As a kind of measurement and guiding device about E.E.G of routine, known example discloses Nos.Sho59-146639 at Japan Patent, Hei2-168932, and Hei2-168933, and disclosed among the Hei2-168934.
In above-mentioned Japanese patent gazette, No.Sho59-146639 discloses a kind of such system, and this system comprises: E.E.G detects the processing section, is used for detecting E.E.G and it is carried out analyzing and processing, audio reproducing apparatus is used for reporting the E.E.G state and this state is returned the feedback object of bringing back to life.For the frequency analysis by means of signal of organism obtains echo signal fast, need a big device at least, because personal computer or DSP have been used for carrying out this analysis.In addition, in this system, be designed to a kind of audio reproducing apparatus as the audio reproducing apparatus of organism stimulus signal, magnetic tape recorder for example, it is distinct on entity that this device and E.E.G detect the processing section.Therefore, E.E.G detect processing section and audio reproducing apparatus be independent device and need to use connector for example the sound connector two devices are connected together.Because this structure, this system are not suitable for and carry and wear, promptly be not suitable for and be installed on the human body or on the clothes.
Thereby as a kind of processor of special applications, personal computer or DSP (digital signal processor) have been applied to frequency analysis, so that finish the analyzing and processing of brain wave signal apace, and bring out the target brain wave signal in real time.Thereby need so far with big device.This is because the fast Fourier transformation algorithm generally is used to the frequency analysis of brain wave signal.Under the situation that E.E.G is analyzed, as an example, in the interval of 0.5Sec, calculate the fourier-transform of 512 one-dimensional data if desired, then must use microprocessor with high-frequency clock CPU or with high performance CPU for example personal computer carry out routine processes.When as a kind of stimulation, when for example using musical sound to stimulate, the sound store medium is a kind of independent device, for example magnetic tape recorder and CD-audio player, and and above-mentioned E.E.G analysis portion be separately to divide.Therefore, when carrying these devices when carrying out biofeedback, be difficult to use because carrying many equipment.

Fig. 3 is the block chart of the other parts of Fig. 1 of being represented by functional device CPU 73 shown in Figure 2 and device body 1.
At first, E.E.G importation 30, carry out filtering by detecting with 21 brain wave signals shown in the figure, thereby obtain the E.E.G frequency domain by 5 inputs of E.E.G input connector from E.E.G.The signal processing of brain wave signal in the CPU that is made of single chip microcomputer 73 subsequently is divided into the frequency domain of β, α, θ and δ ripple, and they are stored in the scratchpad memory 36 in the single chip microcomputer 73.At this moment, all or part of quilt of the information in acoustic information memorizer 75 and aforesaid operations repeat to export one section predetermined time interval to out connector 7 as the E.E.G stimulus signal concurrently.
The ratio that is stored in the brain wave signal of the current generation in the temporary storage device 36 shows that on liquid crystal display 2 or its analog the user also can notifiedly use gauge tap 3,4 to select the level of definite specific E.E.G by the user.Meanwhile, by using gauge tap 3,4 to monitor by signal processing 31 with the ratio of the definite specific E.E.G of relevant mode, be driven and be stored in the state of the particular stimulation signal in the scratchpad memory 36 according to what preceding elder generation determined with selected control mode, decision is the less important new stimulus signal that is written in the acoustic information memorizer 75 down.Then, repeatedly export the stimulus signal of one pre-period from acoustic information memorizer 75 after, the new content that the content of stimulus signal memorizer 75 just is temporarily stored device 36 replaces, and the new stimulus signal of this signal as brainwave feedback.Like this, the effect of study just is reflected in the guiding of specific E.E.G subsequently, and can expect to improve the guiding speed of specific E.E.G.That is, control section 33 changes the content as the acoustic information memorizer 75 of stimulus signal memorizer, and the signal that changes to earphone 22 outputs that for example are connected in output signal adapter 7 and 8, thereby makes the specific E.E.G of target be introduced the user apace.
On the other hand, under the situation of in the middle of the mode that can select by gauge tap 3,4, select a sound advice method or vibration informing mode, when the E.E.G measuring-signal has reached predetermined E.E.G level, the value that the user can notifiedly set is reached, this realizes by the notification voice that produced by interior dress information speaker 10 or by the vibration of notice vibrator 23 generations that link to each other with the adapter 8 that is used for signal output, and need not see display 2.About notifying user's brain wave signal level to reach the method for predetermined E.E.G level, as a kind of method opposite, also can adopt when specific E.E.G begins to guide with regard to output sound or vibration and reach the method that described sound or vibration is stopped when setting level when specific E.E.G with said sequence.
Fig. 4 is a flow chart, and expression is by comprising signal processing 31, the control flow that the single-chip microcomputer 73 of the main handling implement of conduct of control section 33 and analog is carried out.
At first carry out metering system, display mode or similar initial setting (100).
Use gauge tap 3 then, set and whether use the learning effect (101) that is determined.According to the content of initial setting, changing and stimulating the mode that produces figure is different modes (102), (103).
When the operation by gauge tap 3 begins the E.E.G detection (104), produce figure by the stimulation that determines above and produce stimulation (105), (106).In addition, when brain wave signal is measured (107), (108) carry out analyzing and processing (109) to it, and according to set (111) about the mode of whether carrying out specific E.E.G guiding in initial setting, whether the decision stimulus signal will be changed (113).In addition, when specific E.E.G reaches soon, carry out the notice (117) that target reaches.
As mentioned above, this mode is arranged also, promptly notice produces from the beginning, when desired value near the time then stop.
The profile of body 1 card shape as shown in Figure 5, therefore, the signal specific that the comprises organism for example biofeedback of α ripple can be carried out with the place at any time.
In addition, can be according to each user like changing the acoustic information that is stored in the acoustic information memorizer 75 shown in Figure 1.Simultaneously, in middle memory element outside the E.E.G of storage in the scratchpad memory 36 of single chip microcomputer 73 measurement historical data temporarily is stored in, written or printed documents 1 can be connected in the adapter terminal 25 that is used for TV by the input and output connector that is used for storage card 9 that meets the PCMCIA/JEIDA standard, as shown in Figure 6, or be connected in personal computer shown in Figure 9 40 or 41.
Fig. 6 and system shown in Figure 9 comprise, except that body shown in Figure 51, also have as the E.E.G detection of test section and be with 21, be used for listening E.E.G to stimulate the earphone 22 of music, notice reaches the fingerstall notice vibrator 23 and the information speaker 24 of the prearranged signals of organism, the adapter terminal 25 that contains the external memory unit 26 that constitutes by nonvolatile storage and so on, and the feasible TV of understanding easily 27 of signal that shows organism.The example that show this moment on TV or personal-machine as shown in Figure 8.
In addition, because stimulus information can by meet the PCMCIA/JEIDA standard and allow to be input to and stimulate acoustic information memorizer 75 from the adapter 9 of external device (ED) adapter terminal I/O stimulus data for example shown in Figure 1, so can replace original stimulus information with the stimulus information that is suitable for each user.In contrast, by using adapter 9, information that can be obtained the signal analysis result as organism and stimulus signal guiding graphics memory be memory element for example in the adapter terminal externally.
On the other hand, because adapter terminal 25 can link to each other with domestic TV 27, just can provide such facility, promptly thereby the pictorial display that the body 1 of the device of measurement of using out of doors that adorns oneself with and guiding E.E.G is taken home with giant-screen confirms user's health condition of this day, as shown in Figure 7.
As the key technology that realizes E.E.G checkout gear of the present invention, generally speaking there is the guiding organism to enter the method for relaxation state and use microminiaturized mounting technology handle assembly to make the size of the credit card.The following describes completed technology status among the embodiment.
Enter relaxation state about guiding, for example when using sonic stimulation, have
Figure A9512171100311
The sound of the fluctuation for example singing of the stream in brook and the cry of bird is output, thereby makes the user be directed to relaxation state.
Narrowing down to the size of card about handle assembly, must reduce power consumption, so that extend the life of a cell, is portable because card dimensions means.Thereby, importantly use to have the high processing speed and the microcomputer of low power consumption, and only use this microcomputer realization E.E.G processing capacity as much as possible.
These following functions have realized with the size of the credit card.Suppose and can be in a segment length time for example when the user sleeps, to measure E.E.G that so that preserve the historical record of E.E.G, this device is made to measurement result in keeping during 24 hours.As the guiding user voice output that enters relaxation state, this device is made to can provide the high-quality sonic stimulation of stereo high-fidelity to the user.For this reason, make this device can export with the FM acoustic phase with the test sound of level 20KHz.About the demonstration and the measurement of E.E.G, its target is by using FFT (fast Fourier transformation) to carry out signal processing, and most important performance is placed approximately on the ability of just upgrading the E.E.G demonstration in 0.5 second.
Upgrade the E.E.G demonstration in order to carry out in about 0.5 second interval, the result of FFT operation must be approximately just obtained every 0.5 second.The figure on Figure 20 top is illustrated in the power spectrum value of 512 data of sampling during 0.5 second.Under the situation in 0.5 second sampling time, the resolution in the FFT operation is 2Hz.Can not detect the value that 1Hz δ involves its analog with this resolution.If resolution is provided to 0.5Hz, then must carry out FT to 2 seconds data.Yet, when in the time must carrying out display update in 0.5 second, at this moment between in the data that just can not sample 2 seconds.Therefore, use this method, promptly the data of new acquisition in 0.5 second and the stack of the data in past 1.5 seconds, and carried out the FFT conversion, shown in the figure of Figure 20 bottom.Like this, the data that obtain that obtain in the past by means of stack and new per 0.5 second, just can obtain having the E.E.G that 0.5Hz orders resolution frequently.
In the present embodiment, 128 (Pieces) data of sampling in during 0.5 second, and 512 points (Point) of the data of past 2 seconds (0.5 second+1.5 seconds) sampling are carried out FFT, thereby make it possible to the resolution measurement E.E.G of 0.5Hz and carried out the demonstration of its renewal every 0.5 second.Realize this operation by means of microcomputer, just can realize the frequency analysis processing of brain wave signal and need not use big bandwidth-limited circuit to finish a large amount of frequency analysis operations in real time with the device of credit card-sized.
In addition, in order to reduce used unit quantity as far as possible, can finish above-mentioned operation again simultaneously, the reception of above-mentioned E.E.G sampled data and the generation of sonic stimulation also are applicable to same single chip microcomputer to be controlled.These three kinds of processing will be carried out simultaneously.The method that is used for this processing is described as follows.
As mentioned above, after 128 E.E.G data are sampled, began to carry out 512 FFT processing every 0.5 second.According to the result who handles, calculating E.E.G is the ratio of α, β, δ and θ ripple, and the result is shown on liquid crystal display.In the meantime, be carried out incessantly by the voice output of carrying out simultaneously.Meanwhile, E.E.G sampling must so be carried out, and makes E.E.G be sampled with predetermined interval and is not subjected to the interference of output sound.Therefore, by means of the generation cycle be interruption and the control interrupt priority of tens μ seconds, avoid in processing, clashing.This a series of processing is repeatedly carried out with key switch (gauge tap) 3, till finishing measurement.
In order to make by battery-driven equipment miniaturization, importantly definite which processing should be finished by the microcomputer that consumes most of power.On the contrary, if too many processing is assigned to microcomputer, just these processing can not finish on time, unless increase the speed of cpu clock.Yet power consumption increases with the increase of cpu clock speed.On the other hand, can not put into high capacity cell in the device of card size.Thereby, on the size that first important problem is placed on card in, this device is so constructed, and makes that in the restriction that is retained as far as possible little power consumption, processing as much as possible oneself is finished by it.Be described as follows about this structure.

The processing procedure of brain signal is as follows.In order to realize 512 FFT every 0.5 second, 8 buffers are provided, each stores 128 E.E.G data.Buffer is made into circular buffer.4 buffer stores wherein are 512 E.E.G data for the FFT use of sampling in 2 seconds in the past.128 data of 8 buffers displacement in per 0.5 second.Be described in detail below.
As shown in figure 19, CPU comes copy data by transmit 512 E.E.G data of handling with FFT to buffer, and mainly carries out frequency analysis by FFT.On the other hand, in the time of with the signal processing of E.E.G, carry out the sampling of E.E.G data, and use the intervalometer 731 in the RISC microcomputer 73, A/D converter 732, DMAC733 and CPU734 are input to sampled data in the memorizer.At first, the sample frequency that produces by intervalometer 731 be 256Hz promptly in 0.5 second the E.E.G data in 128 cycles carry out A/D with A/D converter 732 and change.When converting, the DMAC733 in the microcomputer sends data to 128 data buffers.128 E.E.G data of every transmission just produce in CPU734 and transmit end interrupt.Thereby this operation is repeated to carry out data acquisition successively.In this way, the RISC microcomputer is fully utilized, and most control operation is assigned to microcomputer.Like this, just realize the hardware configuration of miniaturization, thereby realized the E.E.G test card of credit card-sized.
Figure 10 is the outside figure of an embodiment, wherein can by the mode menu of gauge tap 3 control by it is limited to have only begin/mode of stopping to be simplified.
Though the explanation that provides above is being applied to about the present invention with the situation of brain wave signal as the signal of organism, the present invention can be applicable to not to be other signal of the organism of brain wave signal, for example blood pressure and rapid pulse.In addition, also can use the memorizer in the single chip microcomputer 73 to replace stimulating acoustic information memorizer 75.
