Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, be clearly and completely described the technical scheme in this utility model embodiment, obviously, described embodiment is this utility model part embodiment, instead of whole embodiments.Based on the embodiment in this utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of this utility model protection.
According to expert introduction, when we bow, the anteflexion limit (chin encounters the state of breastbone) can only be 45 °.If when anteflexion amplitude reaches 30 °, just cervical vertebra can be had influence on.If cervical vertebra is in extremely anteflexion exceptional stability state for a long time, will damage cervical vertebra, and this hazard ratio sees taller tens times of computer.
Fig. 1 is the indicative flowchart of the method 100 for measuring cervical vertebra moving illustrated according to this utility model embodiment.
As shown in fig. 1,100 101, utilize sensor to obtain cervical vertebra moving angle, this cervical vertebra moving angle represent cervical vertebra skew main shaft angle, 102, calculate cervical vertebra moving amount based on cervical vertebra moving angle.
Therefore, according to this utility model embodiment, by using sensor, the definite data value of the angle of cervical vertebra moving can be obtained, and cervical vertebra moving amount can be calculated accordingly, thus, accurately can obtain the quantitative values of cervical vertebra moving with numeric form, be convenient to subsequent treatment.
The unit of cervical vertebra moving angle can degree of being (°).
In this utility model embodiment, cervical vertebra once movable can refer to that cervical vertebra comes into play along the direction of departing from original position from original position, arrive another location after---normally near the direction of original position---continue motion more in a certain direction until the process that stops completely.It should be noted that once the process that movable also can refer to that cervical vertebra comes into play along the direction of departing from original position from original position, stop completely when arriving another location; Can also be process between 0 at two movable instantaneous velocitys, above all can think once movable.Consider the integrity of strength vertebra activity, the first situation of employing is described by this utility model.Cervical vertebra moving angle can refer in the once activity of cervical vertebra cervical vertebra the maximum angle of process.Here, in the once activity of cervical vertebra, the position that cervical vertebra stops completely can be identical or different with original position.That is, when cervical vertebra moving repeatedly, each original position can be identical or different, and each stop position also can be identical or different.
According to this utility model embodiment, for the activity each time of cervical vertebra, the average speed to cervical vertebra that should be movable can be calculated, and the activity point of view of cervical vertebra can be obtained by being multiplied with the Active duration of cervical vertebra by average speed.
According to this utility model embodiment, in the once activity of cervical vertebra, comprise two motor processs that direction is contrary, thus two angles can be obtained: the first angle from original position to another location and the second angle from another location to stop position.Between first angle and the second angle, the angle value of the maximum angle of its absolute value is as the cervical vertebra moving angle of this cervical vertebra moving.
First angle and the second angle can be vector, and cervical vertebra moving angle can be scalar.Such as, can the regulation cervical vertebra direction of moving from left to right and the cervical vertebra direction of moving from the bottom up be forward, namely the first angle at this moment obtained and the second angle on the occasion of, and can the regulation cervical vertebra direction of moving from top to bottom toward the direction of left movement and cervical vertebra from right be forward, the first angle namely at this moment obtained and the second angle be negative value.When the first angle and the second angle being compared, only compare the absolute value of the two, and be used as the cervical vertebra moving angle of this cervical vertebra moving with maximum absolute value.When being appreciated that the once activity when utilizing first effective activity threshold to determine whether as cervical vertebra, also only can compare absolute value and this first effective activity threshold of the first angle and/or the second angle.
When determining the first angle and the second angle, respectively with original position and primary importance for calculating with reference to 0 degree of position.
In the specific implementation, sensor can be angular-rate sensor.Certainly, this utility model embodiment is not limited thereto, and those skilled in the art obviously can utilize other any suitable sensors that are existing or exploitation in the future to carry out alternative angular-rate sensor.
After this, will be that angular-rate sensor is to illustrate this utility model embodiment for sensor.
Angular-rate sensor can measure instantaneous velocity, i.e. instantaneous angular velocity (unit: degree/second (°/s)) in real time.According to design requirement, measured instantaneous velocity can be scalar, also can be vector.When instantaneous velocity is vector, as previously mentioned, similarly, can specify instantaneous velocity when cervical vertebra moves from left to right and cervical vertebra moves from the bottom up on the occasion of, and can regulation cervical vertebra from right move from top to bottom toward left movement and cervical vertebra time instantaneous velocity be negative value.
Usually, when people consciously movable cervical vertebra time, all can slightly pause during from original position activity to primary importance and when primary importance turns back to stop position.Based on this, angular-rate sensor can be utilized to the active situation of cervical vertebra between the moving period obtaining twice identical instantaneous velocity of the direction of motion and be 0, and then obtain the movement parameter of each activity of cervical vertebra.
For the activity each time of cervical vertebra, can understand, twice measurement needing travel direction contrary.In the activity each time of cervical vertebra, angular-rate sensor starts to measure its instantaneous velocity in real time coming into play along the direction of departing from original position from original position from cervical vertebra, until the instantaneous velocity of cervical vertebra equals 0, terminate the measurement of this first time when namely arriving primary importance; Then, angular-rate sensor again measures its instantaneous velocity in real time from cervical vertebra in opposite direction, namely from primary importance near the direction of original position comes into play, until the instantaneous velocity of cervical vertebra equals 0, terminate the measurement of this second time when namely arriving stop position.
First time measures and measures with second time is only that direction is different, is measured as example is below specifically described with first time.
During first time measures, angular-rate sensor can be measured and obtain multiple instantaneous velocity.Depend on design requirement and actual needs, multiple instantaneous velocity can be obtained according to the interval preset.Angular-rate sensor itself can have memory function, measure the multiple instantaneous velocitys obtained, or angular-rate sensor can not store during storing each measurement, but in real time the instantaneous velocity measured is sent to its outside.
Measure for this first time, the average speed of cervical vertebra can be calculated.Can calculate the average speed of cervical vertebra when the instantaneous velocity that each acquisition one is new, this average speed can be instantaneous average speed, the average speed namely and between instantaneous velocitys all before.In one example in which, maximum instantaneous velocity and minimum instantaneous velocity can be removed from current obtained multiple instantaneous velocitys, then using the average speed of the intermediate value in residue instantaneous velocity as the cervical vertebra of this first time measurement.In another example, can, after remove maximum instantaneous velocity and minimum instantaneous velocity from current obtained multiple instantaneous velocitys, the meansigma methods of residue instantaneous velocity be asked to be used as the average speed of the cervical vertebra of this activity.Certainly, this utility model embodiment is not limited thereto, and can also calculate the average speed of each cervical vertebra moving according to other any suitable methods.When instantaneous velocity is vector, the average speed during the measurement of this first time is the vector identical with the symbol of instantaneous velocity.
Then, by the average speed during first time is measured with measure for the first time during the Active duration of cervical vertebra be multiplied and obtain the first angle of cervical vertebra moving.Active duration can be obtained by angular-rate sensor inside or outside intervalometer.
In fact, the current instantaneous velocity measured based on angular-rate sensor and the instantaneous velocity of each time point recorded before obtain average speed and and then to obtain current angular be a process quickly, so the instantaneous average speed of each time point can be obtained, then can be multiplied by cervical vertebra Active duration up to the present during instantaneous average speed and this first time are measured and obtain the current Transient activity angle of cervical vertebra.Finally, the first angle of cervical vertebra moving during of maximum absolute value in multiple Transient activity angle being measured as first time.
Similarly, the second angle of cervical vertebra moving during rightabout second time is measured can be obtained.
Then, by comparing the absolute value of the first angle and the second angle, the absolute value of that angle of maximum absolute value is therebetween defined as the cervical vertebra moving angle of this motion of cervical vertebra.
In addition, in order to save memory space, instantaneous maximum first angle so far only can be recorded to and real-time update during first time measures, thus this first time measure during record be instantaneous the first maximum angle all the time, and at the end of first time measures, namely the first instantaneous maximum angle stored is the first angle during the measurement of this first time.Similarly, the second angle during second time is measured can also so be obtained.
According to this utility model embodiment, cervical vertebra moving amount can be calculated based on the activity point of view of cervical vertebra.To be specifically described below.
Can by representing cervical vertebra moving amount in total distance of predetermined Measuring Time section, such as 1 hour period cervical vertebra moving.
Distance can be represented by arc length.First, based on each activity point of view, obtain each activity arc length.Arc length can be calculated by equation (1) below.
L
i=2 π r × (α
i/ 360) ... equation (1)
Here, i represents the index of the cervical vertebra moving angle measured in the Measuring Time section that this is predetermined, and i is natural number; L
irepresent the arc length (unit: centimetre (cm) or millimeter (mm)) corresponding to i-th cervical vertebra moving angle; α
irepresenting i-th cervical vertebra moving angle, can be scalar; R represents cervical vertebra moving radius, can be default default value, and for different crowds, such as adult and child have different default values.Girth/2 π of neck can be utilized to calculate r.For child, r is approximately 5cm, and for adult, r is not more than 10cm usually, so generally, the default value of r can between 5cm ~ 10cm.
Afterwards, the activity arc length sum corresponding with each activity point of view measured during Measuring Time section is calculated
as cervical vertebra moving amount, wherein n is the cervical vertebra moving total degree during Measuring Time section.
In addition, activity point of view can also be utilized to calculate this Motion mapping of cervical vertebra to the line segment length (unit: centimetre (cm) or millimeter (mm)) on this cervical vertebra plane of movement.Line segment length d can be calculated by equation (2) below.
D
i=r sin α
iequation (2)
Wherein, d
irepresent i-th line segment length of the cervical vertebra moving during this Measuring Time section, α
irepresent i-th cervical vertebra moving angle, r represents cervical vertebra moving radius.
Afterwards, the line segment length sum corresponding with each activity point of view measured during Measuring Time section is calculated
as cervical vertebra moving amount, wherein n is the cervical vertebra moving total degree during Measuring Time section.
According to this utility model embodiment, cervical vertebra moving amount is the quantitative values obtained cervical vertebra moving measurement, and it can be notified to user, and also can be stored as historical information for analyzing in the future and.
According to a further embodiment, when swing by a small margin fast head repeatedly time, although cervical vertebra moving amount is very large, this can not play the effect of tempering cervical vertebra, because each movable amplitude is all too little.Therefore, for this situation, this utility model embodiment can also based on cervical vertebra moving angle [alpha]
icalculate the effective movable number of times of cervical vertebra, namely the activity of cervical vertebra reaches the total activity number of times of predetermined amplitude.
If for the once activity of cervical vertebra, its cervical vertebra moving angle [alpha]
ibeing more than or equal to effective activity threshold, is then effective cervical vertebra moving by this activity inventory that cervical vertebra carries out.In addition, can also according to distance L
ior d
iwhether be greater than effective activity threshold of its correspondence to determine whether each activity of cervical vertebra is effective cervical vertebra moving.With first effective activity threshold similarly, effective activity threshold can be empirical value, and can vary with each individual according to everyone own situation.
Expressly, can this effective activity threshold can be manually set.
The unit of effective activity threshold can be angular unit (degree (°)), also can be long measure (unit: centimetre (cm) or millimeter (mm)).Such as, effective activity threshold greatly between 5 ° ~ 15 °, such as, can be able to be 10 °.Such as, when radian, effective activity threshold can between 0.5cm ~ 2cm, and when line segment length, effective activity threshold can between 0.5cm ~ 3cm.
Then, the effective cervical vertebra moving during Measuring Time section is counted, as the effective movable number of times of cervical vertebra.
According to this utility model embodiment, the effective movable number of times of cervical vertebra is also the quantitative values obtained cervical vertebra moving measurement, it can be notified to user separately or together with cervical vertebra moving amount, and also can be stored as historical information for analyzing in the future and.
In one example in which, for each the cervical vertebra moving angle computational activity distance during Measuring Time section, and then cervical vertebra moving amount is obtained.
In addition, in another example, can after obtaining cervical vertebra moving angle at every turn, first determine whether this activity of cervical vertebra is effective cervical vertebra moving based on this cervical vertebra moving angle, then the ability computational activity distance when this activity of cervical vertebra is effective cervical vertebra moving, and then obtain cervical vertebra moving amount.In this case, cervical vertebra moving amount is actually the effective cervical vertebra moving amount during this Measuring Time section.
In other words, can obtain based at least one the cervical vertebra moving angle during Measuring Time section and each the corresponding operating range in this at least one cervical vertebra moving angle.Effective activity point of view of cervical vertebra during all activity point of view of cervical vertebra or Measuring Time section during this at least one cervical vertebra moving angle is Measuring Time section.By the only just computational activity distance when the activity of cervical vertebra is effective cervical vertebra moving, can amount of calculation be reduced, and can memory space be saved.
According to this utility model embodiment, except the left and right flat turn activity of the aforementioned cervical vertebra mentioned, the activity of cervical vertebra can also comprise up and down and left and right upset activity.Up and down referring to is bowed downwards, to be reduced and to layback head this series of activity.Left and right upset activity refers under the prerequisite in face orientation front, and left ear is pressed close to left shoulder, reduction and auris dextra and pressed close to this series of activity of right shoulder.Therefore, can find out, the left and right flat turn activity of cervical vertebra, up and down and left and right upset activity are the activities carried out respectively around three axles perpendicular to each other.
According to this utility model embodiment, angular-rate sensor can be three axis angular rate sensors, to obtain the angle in three kinds of activities above.
Therefore, correspondingly, cervical vertebra moving angle can comprise at least one in up and down angle, left and right flat turn angle and left and right flip angle, cervical vertebra moving amount comprises at least one in up and down amount, left and right flat turn amount and left and right upset amount, and the effective movable number of times of cervical vertebra comprises at least one in effective movable number of times up and down, the effective movable number of times in left and right and the effective movable number of times of left and right upset.
Can understand, first/effective activity threshold can have identical or different value for different activity directions.
In addition, because cervical vertebra moving amount and the effective movable number of times of cervical vertebra may be used for representing the active situation of cervical vertebra within a predetermined period of time, so this utility model embodiment can determine whether to send to user to report to the police to point out user's needs movable cervical vertebra accordingly further.
In one example in which, when meet in following alert if at least one time, to User Alarms:
At least one in cervical vertebra moving amount is less than corresponding activity threshold value; And
At least one in the effective movable number of times of cervical vertebra is less than corresponding effective activity frequency threshold value.
For the different motion of cervical vertebra, activity threshold value and effective activity threshold can have identical or different value respectively.Can rule of thumb or own situation manually arrange activity threshold value, first/effectively activity threshold and effectively activity frequency threshold value.
Certainly, as required, can also be set to when activity and/or the effective movable number of times of cervical vertebra exceed another threshold value to User Alarms, to indicate the activity of cervical vertebra excessive.

In one example in which, this equipment 400 also comprises: meter step unit (not shown), is configured to carry out meter step to the paces of testee.
Usually, traditional pedometer can be worn in wrist, such as sport wrist-watch, but its disadvantage is, meter step is inaccurate.Due to human arm in the process swung and health in traveling process, greatly interference is existed to the result of meter step, especially when hand irregular movement, so the poor effect of meter step, particularly in the process of running, deviation is larger.Physiological parameter (the such as calorie consumption) index calculated is walked so larger with actual numerical bias by meter.
Equipment 400 according to this utility model embodiment may be implemented as the wearable device being worn on head.Because the head of human body keeps static relative to health usually at the volley, even if head movement, the amplitude of motion is also far smaller than the swing of arm, so can reflect the true paces of user really, thus obtains physiological parameter index more accurately.
Specifically, the meter step unit in equipment 400 utilizes three-axis sensor to realize step function.Be described utilizing three-axis sensor to carry out the principle of meter step referring to Fig. 5 and Fig. 6.
Schematic diagram when Fig. 5 illustrates that human body advances, and Fig. 6 illustrates the acceleration utilizing three-axis sensor to sense.
As shown in Figure 5, in Level Walking motion, vertical and two acceleration that advance present cyclically-varying.Specifically, walking receive foot action in, due to center of gravity upwards single foot contact to earth, vertical direction acceleration be in forward increase trend, continue afterwards forward, decentralization bipod touches the end, and acceleration is contrary.Horizontal acceleration reduces when receiving foot, increases when taking a step.
With reference to Fig. 6, can see in walking movement, vertically (x-axis) and advance (y-axis) acceleration of producing and time are roughly a sine curve, and have a peak value at certain point, wherein the acceleration change of vertical direction is maximum, by carrying out detection computations and acceleration rate threshold decision-making to the peak value of track, the step number of user movement can be calculated in real time, also can estimate user's walking distance further according to this.Z-axis represents left and right acceleration.
Namely the sinusoidal path of a walking movement can be obtained by three-axis sensor.
Then peakvalue's checking is carried out.Have recorded vector length and direction of motion last time, by the change of vector length, the direction of current acceleration can be judged, and compare with the acceleration direction that the last time preserves, if contrary, namely represent shortly past peak state, then enter meter step logic and carry out meter step, otherwise give up.By user's walking paces can be obtained to the number of times of peak value is cumulative.
Therefore, according to this utility model embodiment, meter step cell layout can be worn in the equipment of head, because the head of human body keeps static relative to health usually at the volley, even if head movement, the amplitude of motion is also far smaller than the swing of arm, so can reflect the true paces of user really, thus it is more accurate to obtain the meter step result that physiological parameter index more accurately obtains.
In addition, E Wen is also the important indicator of physiological parameter, and traditional method aims at head zone with volume temperature rifle to scan, but volume temperature rifle volume is bigger than normal, and be not suitable for the measurement under kinestate.Consider that human body may have the situation that body temperature is increased to exceptional value at work or in motion, so equipment 300 can also comprise: temperature measuring unit (not shown), be configured to utilize total radiation ther to measure the temperature of testee.And when measuring the body temperature obtained and exceeding safety range, can be reported to the police by notification unit.Utilize total radiation ther to measure the temperature of testee, make the small volume of this equipment 300, and forehead temperature can be calculated accurately, thus make user know the situation of oneself volume temperature more conveniently.
According to the difference of temperature-measurement principle, the design of infrared radiation thermometer has three kinds of methods usually, and that determines the radiation temperature of object by the heat radiation that the all-wave of measuring radiation object is long is called total radiation ther; That determines its brightness temperature by the monochromatic radiation brightness of Measuring Object under certain wavelength is called radiance thermometry; If vary with temperature constant temperature by the ratio of the monochromatic radiation brightness of testee under two wavelength be called two-color thermometry.
Radiance thermometry is without the need to ambient temperature compensation, and emissivity error is less, and temperature measurement accuracy is high, but works in shortwave district, is only suitable for high temperature measurement.The optical system of two-color thermometry can partial occlusion, and affect little by smog dust, temperature measurement error is little, but must select suitable wave band, and the emissivity of wave band is more or less the same.
In this utility model embodiment, total radiation ther is adopted to calculate the temperature of object being measured.Total radiation ther is constant temperature according to the global radiation within the scope of all wavelengths, and what obtain is the radiation temperature of object.Choosing is that radiation signal is very weak because the wavelength of middle cryogenic object is comparatively large in this way, and structure is simple, and cost is lower.After this be briefly described to the principle of total radiation ther.
The relational expression can derived radiator color temperatures by planck formula and be detected between voltage, i.e. equation (3).
V=Ra ε σ T4=KT4 ... equation (3)
In equation (3), K=Ra ε σ, is determined by experiment, such as ε gets the absolute temperature that 1, T represents testee, and R represents detector sensitivity, a represents the constant with atmospheric attenuation distance dependent, and ε represents radiance, and σ represents Si Difen-Boltzmann constant.
Therefore, can determine the temperature of testee by detecting voltage, equation (3) shows that detector output signal and target temperature are non-linear relation, and the biquadratic of V and T is directly proportional, so will carry out linearization process.Obtain the apparent temperature of object after linearization process, radiance need be carried out and be modified to true temperature,
Its corrector is as follows:
Tr in formula---radiation temperature (apparent temperature)
ε (T)---radiance, gets 0.1 ~ 0.9.
Due to the impact of modulation sheet radiation signal, the revised true temperature of radiance is the temperature higher than environment, also needs to do ring temperature compensation and repays, and namely true temperature adds the actual temperature that pressed on ring temperature finally could obtain testee.
Utilize total radiation ther can make the minimized in size of equipment 300, and the temperature results that precision is 0.1 ~ 0.2 can be obtained, can daily need be met completely.
In addition, temperature results can be worked as when being greater than 37.5 DEG C, by notification unit in the mode of sound and/or vibration to User Alarms.
In another example, hardware and/or software filtering can be carried out, to remove interfering data wherein in any suitable moment to the data obtained (cervical vertebra moving amount, meter step data and temperature value).
Such as, for the result of meter step, handheld device has some low amplitude and twitches state (hand shaking be commonly called as) fast, or the equipment that repeatedly shakes fast when certain trick user may come round too short is walked to simulate people, if these interfering datas are not removed, the exact value of meter step can be affected.For this interference, can judge to filter by adding upper threshold value and cadence to detection.The fastest running frequency of usual human body is 5HZ, and that is the interval of adjacent two steps is at least greater than 0.2 second, therefore, by arrange to this interval arrange max-thresholds and can in meter step process filter high frequency noise, namely remove the too fast situation of cadence.Meanwhile, can also, by comparing with acceleration magnitude last time, set up certain threshold value to judge motion whether to belong to effective, effective exercise just can carry out meter step.
