2. definite (see figure 2) of system framework

3. systemic-function and structrual description thereof

In Fig. 1, the physiology signal that the physiological signal acquisition module is gathered, (RR-50 time number extracts) is stored in signal reservoir module 502 in order after treatment, judge module 503 will through the current index of the RR50 signal that extraction be stored in storage module 502 in before the RR-50 signal of extraction compare, and determine that whether RR-50 time present number be than increasing in the past, if RR-50 time number increases, then represent the physiological data condition improvement.

When detailed interpre(ta)tive system function, at first explain the index of expression physiological status, in electrocardiogram and among the pulse wave figure, the R ripple of a heartbeat and next time the interval between the R ripple of heartbeat be referred to as RR at interval, RR is at interval as a kind of index, can represent the autonomic function of human body, RR at interval can be as a kind of accurately and effectively index of expression human body physiological state.

RR pulse wave at interval absolute value at interval corresponding to two successive heartbeats when RR50 is defined in a preset time section (as a minute) measurement pulse wave changes 50ms or more number of times; the value of RR50 is big more; the experimenter loosens more; the value of RR50 is more little; the experimenter is nervous more, and in the daily routines process, the value of RR50 is less than 10 times/minute; in bed is 30 times/minute, exists certain relation between the relaxation state of RR50 and user.The threshold value whether experimenter loosens is about 15 times/minute RR50 value.If the value of RR50 surpasses this value, just think that the experimenter is in relaxation state.

Strictly say, the R ripple of " R " expression heartbeat of RR50, the peak value of pulse wave is corresponding to this R ripple, therefore, RR50 may also be referred to as PP50, that is measures two absolute values between the adjacent P crest value and change the number of times that 50ms or more number of times are PP-50, and the meaning of its measurement is consistent with RR-50.

The structure that is interpreted as now realizing function shown in Figure 1 and needs, Fig. 2 represents the block diagram of this structure.In Fig. 2, CPU is that central microprocessor is used for each module in the control device, and it corresponds to physiologic information acquisition module among Fig. 1, RR-50 extraction module and judge module, the difference in functionality of CPU will be in disparate modules enumeration.

By various control sequences and the various control data of CPU, various instruction set and enquiry form etc. are stored in memory under program (ROM, read-only memory), in addition, ROM also stores various voice messaging model, so that under different instruction, by different language guiding user.

Data memory (RAM, random access memory (RAM)), be used to store pulse wave signal, the index of expression degree of relaxation, measure the time of these indexs etc., and be used as the computer of the inferior counting number of the detection that measurement index index when detecting increases in time, when CPU carries out mathematical calculation, RAM also can be used as the computing zone, and RAM corresponds to signal storage module 502 among Fig. 1.

Man machine interface is sent instruction according to the button of user operation, and show, simultaneously, the running status of display system, result that controlled state and physiological status are compared and trend, keyboard drive circuit in the man machine interface, the operation of control button is transferred to CPU with the push-button type of operating with an interrupt signal.

The pressure-type pulse transducer is a kind of pressure transducer, can be placed on finger or wrist and scratch side, this kind pick off is experienced the vibration of pulse wave, and the waveform that pressure is changed is converted into the signal of telecommunication, through signal amplify and signal condition after and transmit as the pulse wave detection signal.The photoelectric type pulse transducer is a kind of optical pickocff, can be placed on gill lappet position on the finger of user, this kind pick off comprises light emitting diode and photaesthesia transistor, light emitting diode emission light is to finger, after the finger medium vessels was accepted emission light, portions of light reflexed to the sensing crystal pipe, produced the opto-electronic conversion effect behind the photaesthesia transistor acknowledge(ment) signal, the photosignal that produces is through amplifying and nursing one's health the back and transmit as pulse wave signal.

A/D converter is accepted the pulse wave signal that transmits from pulse transducer, is digital signal with analog signal conversion, and with switched digital data transmission to bus, sound source is made up of speaker, and the pulse of RR-50 the number of output that can directly feed back is on the one hand exported the number of times of RR-50 in the unit interval with certain audio frequency and tone, during the RR-50 increased frequency, audio frequency is accelerated, and tone improves, and intensity of sound increases, and when RR-50 number reduces, audio frequency slows down, and tone reduces, and intensity of sound weakens.On the other hand, speaker provides the various promptings relevant with somatosensory to user, and the physiological status that CPU is different according to user is called the different linguistic information models that preset, different physiological statuss of prompting user and degree of relaxation.

The sound source drive circuit is one and is used for the drive circuit of being sounded and showing through the D/A change-over circuits through RR-50 severals pulses of handle extracting by CPU, simultaneously, also is to be used for reading the drive circuit that produces specifically warning or verbal messages from ROM by CPU.

The light beam driver is a drive circuit that is used for being shown through the D/A change-over circuit through the RR-50 pulse number that extracts by CPU the diode light beam, the diode light beam is the array that light emitting diode is formed, shape is similar to light beam, the glittering height of light beam is directly proportional with the RR-50 pulse number, unit interval, RR-50 number was many more, and the glittering number of diode light beam light emitting diode is many more.

Liquid crystal display is used to show the various message and the figure of the demonstration information that forms with CPU, the physiological status, controlled state, speaker and the liquid crystal display that show user correspond to reminding module 504,505 among Fig. 1, display driver is from CPU reading displayed information, be converted to the form that is applicable to display, and the demonstration of control liquid crystal display.

Intervalometer has the common function that clocks, the measurement clock time the during measurement of its output when the measurement data.Another critical function of intervalometer is that a default period sends an interrupt signal by bus to CPU1 in the past at the clock time default by CPU or by CPU, at this moment also provide interrupt signal to be since the last type that CPU presets or after the information that forms of a type.

The I/O interface is other equipment that are used for the device outside, personal computer for example, also for example, the game machine control box sends or accepts the communication means of various information, can be connected with lead or cable between these communication means (by universal or special connector) or standard interface circuit (USB between the equipment such as large-scale amusement device control box, RX23232C etc.) connect, can also adopt multiple remote control mode (for example, infrared remote controller, radio radiological unit etc.).

4. system operation programs is described (see figure 5)

1) when this device of application used as relaxation instructing device, program was as follows:

The program of the device work with above-mentioned functions and structure is described now: behind the power connection of device, the pressure-type pulse transducer and (or) the photoelectric type pulse transducer begins to detect pulse wave, the pulse signal that obtains is converted to digital signal by A/D converter, and exports bus to.

When user pushes button when sending interrupt signal, device begins to measure, and R-50 number of measure R is with the relaxation state of definite user, simultaneously, user is by adopting the relaxation training method that is suitable for oneself to reach relaxation state as early as possible, and the many formulas of the mode of loosening are various, please refer to the user's manual of device.

In order to judge the relaxation state of user, equipment can be set that manual identification is measured and discern different identification measurement patterns such as measurement automatically, the manual identification measurement pattern is to think when beginning to reach relaxation state when user, send instruction by keyboard, pattern with external interrupt is sent an external interrupt signal to CPU, CPU receives and begins to start the identification measurement pattern behind this signal, discerns measurement pattern automatically and be after beginning to detect pulse signal in the stipulated time (time parameter can by the keyboard setting).Intervalometer sends an interrupt signal automatically and gives CPU, and CPU receives signal and begins to start the identification measurement pattern.

After CPU identification measurement pattern starts, this is put intervalometer and produces an interrupt signal at regular time interval (for example a minute) and produce another interrupt signal in the stable time in the past, the previous period is the interval that is used to measure expression physiological status index, the i.e. variation of each physiological status index in each interval, this interval are 4～6 minutes.

On the contrary, a back time period is the interval that finishes up to measuring, even notice through after the suitable effort at this interval user, also can not reach the state that more loosens again.

Then, when one of 12 report of intervalometer in interval regular time are interrupted, CPU stores pulse wave signal to the given time period in RAM, calculate the index of each physiological status then based on the pulse wave signal of storage, promptly in order to extract maximum point from pulse wave, CPU at first carries out the time differentiate to pulse wave, by determining that time-derivative is whole clock times that zero clock time is determined the flex point place in the waveform, secondly, CP determines the maximum or the minimum of each flex point from the slope (time-derivative value) of flex point waveform on every side.For example, for given flex point, CPU calculates the sliding average of small-sized slope in the last specific period of flex point, if this sliding average for just, then flex point is a maximum, and if it is minus, then flex point is a minimum.

Next, CPU determines to be right after the minimum in the maximum front of each extraction.The pulse wave amplitude at maximum and minimum place is read from RAM, and the difference between determining, if this difference surpasses predetermined value, then the clock time of this maximum is defined as the peak value of pulse wave.After the whole pulse waveforms that extract were all carried out this peak detection process, the clock time that takes place based on these peak values calculated two peak-to-peak intervals of adjacent pulse wave (being equivalent to twice RR between heartbeat at interval).

CPU determines that from the pulse wave intervening sequences ground that obtains adjacent pulse interlude is poor.Next, whether each that check these time differences surpasses 50ms with the acknowledging time difference, and counting surpasses the fixed number of the time difference of 50ms, and is set to RR50.

CPU is stored in the RR50 value the calculated clock time of reading with current measurement among the RAM from intervalometer, if the RR50 of storage is not first RR50 that obtains after user pushes button, whether the more current RR50 of CPU increases to some extent than the RR50 that previous measurement obtained that (that is, CPU judges that user points out this effect.If at this moment the eyes of user are closed in order to help loosening, in this case, be necessary to provide certain device that does not rely on vision to point out user.Therefore, CPU1 can be by one section melody that can not disturb the relaxation training of user of loudspeaker plays.

In addition, CPU judges whether user is in enough relaxation states.The reason of carrying out this judgement is to believe for relaxation state the one fixed limit is arranged.That is, in case user sufficiently loosens, can not surpass this point on loosening has further raising, and the change of RR50 value is also with saturated.If reached this saturation conversely speaking,, can think that then user has reached the state that enough loosens.

The RR50 value increases with the continuation training of user, and has shown saturation.After 1 minute 30 seconds, the RR50 value reaches 15 times/minute, thinks that in this scope user is in relaxation state in the training beginning.The RR50 value is saturated after training begins about 4 minutes.

For detecting this saturation, RR50 value in the current RR50 value that CPU will measure at every turn and the last measurement and judges whether current RR50 value increases mutually, if current RR50 value increases, then CPU will give the counting increase+1 of RAM, and check whether new count value surpasses certain specific value.Carrying out this process is for fear of incorrect judgement, promptly only rely on the RR50 value and no longer change and just think that user is in the relaxation state, even the relaxation state of user begins just not improve from measurement at all.At this moment, if count value is lower than specific value, then CPU does not carry out the inspection of RR50 saturation, and waits for from the interruption report of intervalometer when the specified time interval.

On the contrary, if count value surpasses a particular value, whether the then RR50 value calculated from RAM reads out in over a special time process of CPU, and the change of inspection RR50 value is in a certain specific scope.

It should be noted that the particular value here is meant the threshold value that is used to judge relaxation state, and be to be provided with according to the index of using.For example, if use RR50 as index, then threshold value is 15 times/minute.In addition, said here specific scope is to be used for the standard whether judge index is in saturation.Equally, specific scope also is provided with according to index.Consider measurement error, when the change between present value of calculation and the value of calculation in the past is between-10% to+10%, think that RR50 is in saturation.

In the judgement of this type variation, the value explanation user beyond particular range does not sufficiently loosen.Therefore, the situation that does not exceed particular value with count value is the same, and CPU still waits for the interruption of self-timer.Mode when relaxation state is insufficient, repeats aforesaid operations according to this.

On the contrary, he has been in the state that enough loosens if the RR50 value in particular range, is then pointed out user.If at this moment the eyes of user are closed, can point out this fact to user by one section melody, the melody that this melody uses during with transition period of pointing out him to be in relaxation state to user is different.Simultaneously, the setting of CPU release timer, and sum up measurement result.

Afterwards, when user pushed button, CPU was based on the raising on the measurement quantification degree of relaxation of just having carried out, and the degree of pointing out user to loosen.

Can consider to calculate the degree of loosening with following method.That is, can use method based on the ratio between the daily value of variation in the currency of index and index.In this case, RR50 value each on one section specified time interval is in the past measured initial moment place and is obtained, and is stored among the RAM3 the local different place with the RR50 value that is used for being stored in measuring process storage calculating.Calculate the meansigma methods of these RR50 values of storing on the specified time interval in the past, and be defined as the daily value of RR50.In this case, the last RR50 value that obtains is compared with this meansigma methods in measuring process.The multiple (multiplication factor) that increases or reduce is regarded as the degree of relaxation of user.

The test of the daily value of user also can adopt following manner to obtain, promptly require user after sitting quietly 5 minutes, when the individual is in tranquility, do not do any relaxation training, user is pressed lower keyboard, send instruction from keyboard and give CPU, start " initialization value measurement pattern ", CPU send instruction sample respectively three one minute, calculate the quantity of RR50 in the per minute, three RR50 quantity in a minute are average, be about to that RR50 number obtains average RR50 value divided by 3 in three minutes, this numerical value is kept in the RAM automatically, as daily value and user RR50 every day measured value relatively, all behind relaxation training RR50 the more daily value person of increasing of number, all can be considered the evidence of relaxation state improvement.

The user relaxation state can represent with bar diagram, bar diagram, block diagram or sector diagram, can adopt ten point system or 100 fens systems, increases or the degree that reduces represents that with hundred-mark system the account form of multiplication factor is:

Account form (1)-" random measurement pattern "

Relaxation state improves degree (multiplication factor RG)=preceding RR-50 number of RR-50 the number/training in training back

Account form (2)---" desired value measurement pattern "

Relaxation state improves degree (multiplication factor JG)=RR-50 number/desired value in training back

In order further clearly to represent degree of relaxation and state thereof, expression degree of relaxation and loosening of state thereof after giving a rank, multiplication factor are reresented user, this rank is represented with ten point system, is made of letter and number, and the multiplication rank is represented mode (as shown in Figure 3).

Multiplication factor to the expression degree of relaxation is reresented user after giving a rank.That is, if multiplication factor less than 1.0, then its rank is " G0 ", if multiplication factor is equal to or greater than 1.0 but less than 1.2, its rank is " G1 ".If multiplication factor is equal to or greater than 1.2 but less than 1.4, its rank is " G2 ".If the factor is equal to or greater than 1.4 but less than 1.6, its rank is " G3 ".If factor G is greater than 1.6 less than 1.8, its rank is " G4 ".The rest may be inferred.Rank is high more, and degree of relaxation more.In addition, show jointly that corresponding to these rank labellings and rank then user can directly be learnt his degree of relaxation if in display, use.

Also be fine to the details of user prompting about multiplication factor or class value.For example,, can provide a piece of news to user if class value is " G0 ", as " degree of relaxation not improve ", and if class value is " G1 ", can provide a piece of news to user, as " degree of relaxation has very little improvement ".Similarly, when class value was " G2 ", user can be received the message such as " the less improvement of degree of relaxation ", received the message as " relaxation state has improvement " when class value is " G3 ".When class value is " G4 ", user will be received the message such as " degree of relaxation has improvement ".

Because as the result of this prompting, user can be confirmed the effect of current training at once, thus should training very attractive to user, make them wish to continue to practice.

The another kind of method of assessment degree of relaxation can be imported desired value by hand from keyboard, or adopts upper PC by exterior I/O interface (for example USB interface) input desired value, CPU with this information storage in RAM.In case finished measurement, CPU compares the rate of change that obtains with default target, and respond this results suggest user relatively, multiplication factor with respect to the desired value of rate of change is endowed a rank, respond this class value prompting user, the multiplication factor less than 1.0 illustrates that current rate of change does not reach desired value.Therefore, when user provides message such as " miss the mark value ", continue to strengthen training to encourage him.

On the other hand, in case passed through the dwell time that presets, intervalometer produces an interruption, because can not expect the relaxation state that reaches suitable at this point, even user is proceeded relaxation training.CPU prompting user is measured and is stopped, and the setting in the release timer, therefore measures and is ended automatically, receive this prompting after, user can begin measurement again after the time of waiting for a weak point.Carry out the result of relaxation training as mode according to this, not only can point out user he whether entered relaxation state, and can be when he reaches this state or he point out user when unlikely reaching this state apace.

Just as used herein, rate of change is represented the intensity of variation by the daily value of the index of current calculating and index or the desired value that presets, yet, also can represent the variation of the desired value calculated before the desired value of current calculating and current measurement begin with rate of change.If a kind of situation in back then might be confirmed the variation of degree of relaxation in real time in measurement.

In this case, also can adopt a kind of scheme to user prompting degree of relaxation.Yet, more preferably also comprise a kind of suggestion device that instructs user specially, make him can improve degree of relaxation.For example, a kind of scheme of considering is to instruct the user deep breathing of slowing down, and special-purpose intervalometer for this purpose is provided when degree of relaxation does not improve.In this case, if deep breathing number of times corresponding to multiplication factor or class value.Degree of relaxation in the measuring process can easily be brought up to desired degree.At this moment be necessary to instruct in this case the respiratory frequency of user, when promptly the degree of relaxation of failing to reach expectation when user is improved, can be according to multiplication factor or multiplication factor number of levels, select suitable respiratory frequency, send the breathing inducement signal by speaker, require user to follow the respiratory frequency that instructs in the speaker and carry out depth of respiration, loosen to reach greatly.Relaxation state and inductive respiratory frequency relation see the following form.The multiplication rank is low more, the inductive respiratory frequency that needs is low more, respiratory depth is dark more, and to adopt the ventral breathing method, otherwise, when the multiplication rank reaches the G4 level, do not need to adopt the breathing abductive approach, when having only relaxation state not reach expected value, can promote user to enter deeper relaxation state (see figure 4) to deeply breathe by inducing and instruct user than the lower speed of determining of breathing rate.

Can finish above-mentioned prompting by liquid crystal display or speaker, also the data of needs can be delivered to external device (ED) via the I/O interface, make the judgement of degree of relaxation by external device (ED).When external device (ED) was judged degree of relaxation, user used the button in the input equipment and this device is set and is in data transmission state.CPU reads with Measuring Time and is stored in RR50 value among the RAM then, and sequentially they is delivered to the I/O interface.Transfer to upper PC by USB interface or RX233C interface.Therefore, by the operation host computer, the process that doctor or other director can clear and definite user relaxation states, and obtain guidance about degree of relaxation.When determining degree of relaxation, can provide by the director (for example doctor) of host computer or operation external device (ED) corresponding to the guidance of this degree of relaxation by external device (ED).

2) when this device of application used as the biofeedback training device, service routine was as follows:

When implementing biofeedback training, each training is set the higher limit of training time and training objective value (being described in greater detail below the rate of change among the RR50) in the present embodiment, from external device (ED) these values are set by doctor or other directors.That is, the director is used to be provided with the order of higher limit and desired value with keyboard input, and (also can adopt external device (ED) host computer input instruction), CPU gathers the information of transmitting and is stored among the RAM then.

Then, when user pushed button, CPU detected this action and trains beginning and intervalometer is set to produce an interruption in particular time interval from body.After past time corresponding to the higher limit of training the duration, as mentioned above, CPU also is provided with intervalometer and produces another interruption.After pushing button, the focusing on of user loosened, and beginning is from the body training, advises etc. to loosening.

After the power connection of apparatus main body, the detected pulse wave signal of kymoscope is exported via A/D converter at certain time point.When intervalometer when one of gap report interrupts at a fixed time, CPU picks up the pulse wave signal of reading from A/D converter and is stored in the RAM, calculates RR50 according to the degree identical with such scheme, and it is stored among the RAM with clock time of measuring.Be the RR50 value that obtains to the user prompting then, CPU produces the speech message based on the RR50 value, is the information component model of reading from ROM, and it is forwarded to the sound source driver.As a result, the form prompting user to sound by the speaker of the current RR50 value of representing physiologic information.As a result, user is known that RR50 value that he has just heard has reached and is become big.As a result, reached biofeedback.When showing biofeedback effect, the situation of user improve greatly with the fluctuation change in the pulse wave interval, thereby the RR50 value increases gradually.

On the contrary, when biofeedback did not produce any effect, the relaxation state of user remained unchanged or has deteriorated into more nervous state.Therefore, the RR50 value is constant or a less reduction arranged.Therefore, the increase by listening to the RR50 value that goes out from speaker or reduce, user can be confirmed his relaxation state in real time, and with its as target from the body training.

On the other hand, in each time of measuring, CPU is with the RR50 value of measuring in certain concrete interval process in the past, and it comprises preceding at least RR50 value one-shot measurement and current, and calculates two variation tendencies between the value.CPU determines that the direction whether current RR50 value increases to tensity changes then, and the result of this judgement of prompting user.

Then, CPU repeatedly handles to point out user at the specified time interval place that is arranged in the intervalometer with the RR50 value.User continues to train from body according to this prompting. and in this process repeats, might allow intervalometer report an interruption in the past owing to one period corresponding to the higher limit of training from body.It is owing to carry out to such an extent that be not fine from body training, also unlikely produce any effect even expression continues from the body training again.Thereby CPU prompting user finishes to train from body.User responds this prompting, ends to train from body.

When body training can not produce any effect as mentioned above, CPU provides specific indication to tell on from training to user.An example as these indications is to instruct user to carry out the various relaxation trainings of describing in detail in the said procedure.Yet carry out the relaxation training of single exercise form by mode according to this, the effect of his effort of user there is no telling, but in this implementation procedure, used under the situation of body training method, can knowing of biofeedback.Therefore, after the indication of implementing the CPU guidance, user is by restarting the effect that can know these guidances from the body training according to order same as described above with biofeedback.

Do not having prompting to stop under the situation of body training, when user pushed button with the end training again, CPU detected this operation and termination process.Then, CPU starting process is to calculate the rate of change as the RR50 of the autonomous training result that has just carried out.Promptly in the information from be stored in RAM, CPU reads training and has just begun the RR50 value that the back obtains, RR50 value and the clock time when measure R R50 that training has obtained before just having finished immediately.CPU calculates the clean training time based on the zero-time and the concluding time of measuring then, and according to the rate of change of following Equation for Calculating index (is the RR50 value at this).Then the result is stored among the RAM.

The rate of change of index (RR50)=[(desired value when body training finishes-when body training beginning desired value) ÷ training time] * 100%, rate of change is represented with percentage ratio.

By calculating this rate of change, the effect of biofeedback can be quantized.That is, rate of change is represented the intensity of variation (and relaxation state) of index in the time per unit, and this value is big more, and it is fast more that user enters relaxation state, and the effect of biofeedback produces soon more.

Except above-mentioned process, CPU can give a rank to the effect that produces from the body training by means of the program identical with above-mentioned implementation procedure, if and it is shown to user. for example the rank of Ji Suaning is " 0 ", then CPU provides above-mentioned various indications to user, and carry, in case show after user oneself enters relaxation state to try again that suggestion content is with reference to above-mentioned implementation procedure from the body training.

CPU measures the rate of change of RR50 with the end of each training section clock time is stored among the RAM.Simultaneously, CPU shows RR50 rate (trend, and being presented on the display over time with diagrammatic form.As a result, RR50 value becomes big on the basis of body training if carry out every day at user, and then user is known to train from body and told on.In addition, when user was watched the degree of this increase, he can be directly acquainted with its relaxation state and improve to such an extent that how soon have.On the contrary, if the rate of change of RR50 value is flat or descends that then user knows that its effect from the body training is unsatisfactory.

In addition, the data of relevant this tendency information can be delivered to external device (ED), for example personal computer.At this moment, user utilizes the button handle assembly on the keyboard to be arranged to be in the data forward mode.As a result, CPU reads and is stored among the RAM tendency information and delivers to I/O interface 15.Tendency information is issued to the host computer in the external device (ED).Microprocessor in the personal computer is stored in measurement result in internal RAM or the hard disk then.As a result, doctor or other directors pass through the process of the clear and definite user of operation personal computer energy from the body training, and can be provided as the target to the doctor's advice training partly of user daily routines.

When repeating on body training the basis,, also will slowly disappear in the variation of the rate of change of RR50 even training continues in every day.State has promptly reached capacity.This state can be considered target and reaches.Therefore, for detecting this state, when each training section finished, CPU is the desired value of setting and for the actual measured value of the rate of change of RR50 value before body training beginning relatively.If measured value surpasses desired value, then the desired destination value is considered as reaching, and sends a prompting to user, for example, " has obtained enough effects from the body training, has kept current state.”

On the other hand, intervalometer timing (for example each minute) is sent an interrupt signal to CPU, after CPU receives interrupt signal, extract the multiplication factor numerical value that is stored among the RAM immediately, find out the corresponding output pulse number of multiplication factor by look-up table, and according to presetting regulation produces corresponding umber of pulse in the table, this umber of pulse is delivered to actuator by the I/O oral instructions, the numerical value of multiplication factor is big more, proves that the user degree of relaxation is high more, and the pulse number that CPU produces is many more, thus, the movement range that actuator produces is big more, and actuator is if with digital quantity control, for example actuator such as motor, then because the pulse number increase, the angle of corner increases, and based on concrete how many pulse numbers of generation, then needs to determine according to the 26S Proteasome Structure and Function of actuator self.Equally, actuator then because the digital quantity that CPU produces increases, is changed the corresponding raising of analog quantity that produces by D/A if by analog quantity control, corresponding the increasing of control voltage that analog drive circuit produces, and the corresponding increase of action of electrical equipment generation is carried out in simulation.
