[0052] 其中,数据处理模块用于对运动数据检测单元11所检测到的运动运动加速度进行处理,例如根据运动数据检测单元11所检测到的各方向的加速度计算合加速度值,并对所得到的运动加速度的曲线进行滤波处理,以去去除噪音和尖锐部分使曲线平滑,当然还可进行其他处理。 [0052] wherein the data processing module for the motion data detection unit 11 detects the acceleration of movement of the moving process, for example, calculates the acceleration in each direction of motion data detection unit 11 detects the acceleration values ​​together, and the resulting motion acceleration curves of the filtering process, to remove noise and to make the sharp part smooth curve, of course, also other processing. 在实际使用中,由于运动时前进方向与重力方向的加速度较大,而其他方向的加速度对步伐的计算影响较小,因此数据处理模块计算合加速度时,可不用计算各方向的合加速度,仅对运动时前进方向的加速度或者对运动时前进方向与重力方向的加速度值进行加权修,使得合加速度信号更加清晰明显,计步更加准确。 In actual use, since the forward direction of motion and the direction of gravity greater acceleration, an acceleration in the other direction little effect on the calculated pace, so that the data processing module calculates the resultant acceleration, can not calculate the acceleration in each direction of engagement, only the forward direction when the acceleration or the acceleration values ​​of the forward movement direction of the movement direction of gravity weighted repair, such that the combined acceleration signal more clearly evident, more accurate step counting.

[0053] 波峰波谷判断模块用于判断数据处理模块所得到的合加速的波峰和波谷,并将判断结果发送至控制单元12。 [0053] The peaks and troughs acceleration determining means for engagement of the crests and troughs is determined by the data processing module obtained, and the determination result to the control unit 12. 在加速度曲线上,从波谷到波峰可以认为迈步开始,从波峰到波谷可以认为是落脚踩地,一个“波谷-波峰-波谷”可以认为是一个走步周期,因此每当波峰波谷判断模块判断出一个相邻的波峰和波谷时,则代表完成一步,控制单元12指示计数模块使表征运动步数的计数值加1,即,运动步数加1,如果波峰波谷判断模块没有判断出相邻的波峰和波谷,则控制单元12不进行相应的指示,计数模块无变化,即运动步数不变。 On the acceleration curve, from the trough to move the peak start may be considered, from peak to trough may be considered off the foot, a "trough - peak - trough" may be considered a walking period, so whenever peaks and valleys determining module determines a neighboring peaks and troughs, represents one step, the control unit 12 indicates that the count value of the counting module characterization another step movement, i.e., movement plus a number of steps, if the peaks and valleys is not the determining module determines that the adjacent peaks and troughs, the control unit 12 does not indicate the corresponding counting module unchanged, i.e. the number of steps the same motion.

[0054] 在一种实施方式中,波峰波谷判断模块可通过下述方法判断运动加速度的波峰和波谷:当所述加速度超过所述基准值的第一上限,并且随后又降低到所述基准值的第一下限时,波峰波谷判断模块可判断出现一个波峰;当所述加速度低于所述基准值的第二下限,并且随后又超过所述基准值的第二上限时,波峰波谷判断模块可判断出现一个波谷。 [0054] In one embodiment, the peaks and valleys motion acceleration determining module may determine the peaks and valleys by the following method: when the acceleration exceeds the first upper limit reference value, and subsequently reduced to the reference value a first lower limit, peaks and valleys determination module determines a peak appears; when the acceleration is lower than the lower limit of the second reference value, and then exceeds the second upper limit and the reference value, the determination module may be peaks and valleys Analyzing a trough appears. 其中,所述基准值的第一上限指的是该基准值加上第一变化量所得的值,所述基准值的第一下限指的是该基准值减去第一变化量所得的值,所述基准值的第二上限指的是该基准值加上第二变化量所得的值,所述基准值的第二下限指的是该基准值减去第二变化量所得的值。 Wherein the first upper limit reference value refers to a value obtained by adding the reference value of the first variation, the first lower limit reference value refers to a value obtained by subtracting the reference value obtained in the first variation amount, the second upper limit reference value refers to a value obtained by adding the reference value of the second variation, the second lower limit reference value refers to a value obtained by subtracting the reference value of the second variation amount. 在实际应用中,所述基准值、第一变化量、第二变化量均可根据经验或每个使用者的具体情况进行设定。 In a practical application, the reference value, a first variation, a second variation amount can be set according to experience or particular circumstances of each user. 当然所述基准值还可采用动态基准值,即,以一定时间段内的合加速平均值作为基准值,例如,可以当前时刻的前2秒内所有加速度的平均值作为动态基准值,在实际应用中,可根据具体需要设定相应的时间。 Of course, the reference value may also be dynamic reference value, i.e., a certain time period in order to accelerate the closing of the average value as a reference value, for example, an average value of acceleration within all 2 seconds before the current time as a dynamic reference value, the actual applications, may be set according to specific needs the corresponding time.

[0055] 在实际应用中,由于加速度传感器会检测到许多干扰信号,表现在加速度曲线上就是有的波峰波谷并不代表实际完成了一步,为了更精确计量运动步数,计步单元14还设置了计时模块,其用于计算当前波峰的时间间隔,即,加速度从所述基准值的第一上限到所述基准值的第一下限的时间间隔,以及当前波谷的时间间隔,即,加速度从所述基准值的第二下限到所述基准值第二上限的时间间隔,并将计算结果发送至控制单元12。 [0055] In practice, since many of the acceleration sensor detects an interference signal, and in the acceleration curve is that some peaks and valleys do not represent the actual completion of the step, in order to more precisely metered movement number of steps, the step count unit 14 is also provided a timing module, for calculating the peak current time interval, i.e., the upper limit of the acceleration from the first time of the first reference value to a lower limit value of the reference interval, the time interval and the current trough, i.e., the acceleration from the second lower limit reference value to the upper limit value of the second reference time interval, the calculation result to the control unit 12. 控制单元12判断当前波峰的时间间隔和当前波谷的时间间隔是否处于设定室间隔范围内,例如判断当前波峰时间间隔是否在0.3秒到0.5秒之间,如果是则判定当前波峰有效。 The control unit 12 determines the current time interval and the peak current time interval is within a trough septal set range, for example, the peak current is determined whether the time interval between 0.3 seconds to 0.5 seconds, if it is determined that the current peak is valid. 当同时判定当前波峰和波谷有效时,则控制单元12才指示计数模块使表征运动步数的计数值加1,如果有一个无效则不进行指示,即,不计数。 When both current peaks and troughs is determined valid, the control unit 12 before the count value indicating the number counting module characterizing movement of another step, if there is not a valid instruction, i.e., does not count. 在实际应用中,此处的设定时间间隔为根据经验及具体情况设定的一个时间范围,其与使用者完成一步所需时间有关,可根据使用者的身体状况、年龄进行设定或者采用一个较普遍的统计值。 In practice, the set time interval here is based on a time range of experience and the specific circumstances set, the time required to complete the user step-related, according to the user's physical condition, age or the use of set a common than statistics.

[0056] 进一步地,为了更准确的计量运动步数,计数模块还用于计算当前波峰波谷和前一波峰波谷的时间间隔,并将计算结果发送至控制单元12。 [0056] Furthermore, for more accurate measurement of the number of movement steps, counting module is further configured to calculate the current peaks and valleys and peaks and valleys of the previous time interval, and transmits the calculation result to the control unit 12. 控制单元12判断当前波峰波谷和前一波峰波谷的时间间隔是否处于设定时间间隔内,如果是,则指示计数模块使表征运动步数的计数值加I ;反之则判断当前连续行走步数,即,当前连续出现的满足设定时间间隔的波峰波谷个数,如果当前连续行走步数小于设定值,则控制单元12指示计数模块清零并重新计数,反之则指示计数模块使表征运动步数的计数值加I。 The control unit 12 determines whether the current peaks and valleys and peaks and valleys of the previous time interval is within a predetermined time interval, if so, the count value indicating the number counting module move step plus characterization I; Analyzing this otherwise continuous many steps, That is, to meet the current number of consecutive peaks and valleys of the set time interval, if the current step number continuously traveling than the set value, the control unit 12 instructs the count is cleared and the counting module, otherwise indicating that the counting module move step Characterization plus count value I. 此处的设定时间间隔为正常行走和跑步时相邻两步的时间间隔,例如0.3秒至1.8秒,如果相邻两步的时间间隔不在此范围内,则表示这两步不是连续行走状态下的相邻两步,此时通过判断已经连续行走的步数可排除计步初始阶段的误差或者仅计量超过一定数量的连续行走步数。 Adjacent to the two-step interval set time interval is here the normal walking and running, for example 0.3 to 1.8 seconds, if the interval between consecutive two steps is not within this range, it indicates that these two steps are not continuous walking state adjacent two steps at this time is determined by the number of consecutive steps walking step count error can be excluded or only the initial stage of continuous measurement over a number of many steps. 例如为了排除计步初始阶段的误差,该设定值可设置为4-10步,当出现相邻两步的时间间隔不处于设定间隔范围内时,如果连续行走步数小于该设定值,则表示该连续行走步数为误差出现的步数,不代表实际行走步数,需要清零并重新计步。 For example in order to exclude the error count step of the initial stage, the setting value can be set to step 4-10, when there is an adjacent two-step interval is not within the range of the set interval, if the continuous many steps than the value , it indicates that the continuous walk step number of the step number error occurs, it does not represent the actual number of walking steps, and need to be cleared again pedometer.

[0057] 请参阅图2,本发明第二实施例提供的血氧测量仪包括血氧数据采集单元10、运动数据检测单元11、控制单元12、血氧数据处理单元13、计步单元14和显示单元15。 [0057] Referring to FIG 2, a second embodiment of the present invention provides oximeter comprises blood oxygen data acquisition unit 10, the motion data detection unit 11, the control unit 12, the blood oxygen data processing unit 13, the count unit 14 and step The display unit 15. 其中,控制单元12包括模式选择模块20和使用者状态判断模块21。 Wherein the control unit 12 includes a mode selection module 20 and the user state determination module 21. 模式选择模块20用于为使用者提供计步模式和血氧测量模式选择,并将选择结果发送至控制单元12,控制单元12根据选择结果控制进入相应的模式。 Mode selection module 20 to provide a step mode and oximetry meter mode is selected as the user, and the selection result to the control unit 12, the control unit 12 controls according to the selection mode into the respective results. 使用者状态判断模块21用于根据运动检测单元11的检测数据判断使用者是否处于运动状态,并将判断结果发送至控制单元12,控制单元12根据判断结果控制血氧数据处理单元13执行相应的数据处理模式来得到血氧值。 User status determination module 21 for determining whether data detected by the motion detection unit 11 whether the user is in motion, and transmits the determination result to the control unit 12, the control unit 12 controls the blood oxygen data processing unit 13 according to the determination result of executing the corresponding data processing mode to obtain oxygen values.

[0058] 具体地,使用者状态判断模块21根据所述运动数据检测单元11所检测到的运动数据判断使用者的状态,即使用者是处于静止状态还是处于运动状态,控制单元12根据判断结果选择相应的数据处理模式。 [0058] Specifically, the user state determination module 21 based on the motion data detection unit 11 detected movement data to determine the user's status, i.e., the user is at rest or in motion, the control unit 12 based on the result select the appropriate data processing mode. 当使用者状态判断模块21判断使用者处于静止状态时,控制单元12选择静止状态数据处理模式,并指示血氧数据处理单元13执行静止状态数据处理模式来得到血氧值,即,血氧数据处理单元13基于所采集的血氧数据得到血氧值;当使用者状态判断模块21判断使用者处于运动状态时,则控制单元12选择运动状态处理模式,并指示血氧数据处理单元13执行运动状态数据处理模式来得到血氧值,即,血氧数据处理单元13基于所采集的血氧数据和所检测到的运动数据得到血氧值。 When the user status determination module 21 determines that the user is in a stationary state, the control unit 12 selects the still state data processing mode, the blood oxygen indication of the data processing unit 13 performs data processing mode to a stationary state value obtained oxygen, i.e., oxygen data the processing unit 13 to obtain oxygen value based on the collected data oxygen; when the user status determination module 21 determines the user is in motion, the motion state of the processing unit 12 selects the control mode, and instructs the data processing unit 13 performs the blood oxygen motion status data processing mode to obtain the value of the oxygen, i.e., oxygen-based data processing unit 13 and oxygen data collected athletic data detected value obtained oxygen.

[0073] 作为本发明的另一种技术方案,本发明还提供了一种计步方法。 [0073] As another aspect of the present invention, the present invention also provides a method of counting steps.

[0074] 如图5所示,本发明提供的计步方法包括下述步骤: [0074] As shown, the step counting process of the present invention comprises the following five steps:

[0075] S1:测量使用者的运动加速度,并得出所述运动加速度的变化曲线;S2:基于加速度基准值判断所述加速度曲线的波峰和波谷;S3:每当判断出一个相邻的波峰和一个波谷时使表征运动步数的计数值加I。 [0075] S1: measuring a user's motion acceleration, and deriving the motion acceleration curve; S2: determining a reference value based on the acceleration of the acceleration profile of peaks and troughs; S3: whenever it is determined that a neighboring peak and a valley when the number of movement steps characterized count value I.

[0076] 在一种实施方式中,可通过下述方法判断运动加速度的波峰和波谷:当所述加速度超过所述基准值的第一上限,并且随后又降低到所述基准值的第一下限时,可判断出现一个波峰;当所述加速度低于所述基准值的第二下限,并且随后又超过所述基准值的第二上限时,可判断出现一个波谷。 [0076] In one embodiment, the motion acceleration can be determined by the peaks and valleys of a method: when the acceleration exceeds the first upper limit reference value, and subsequently reduced to the reference value of the first limit, a peak appears may be determined; when the acceleration is lower than the lower limit of the second reference value, and then exceeds the second upper limit and the reference value, a trough may be determined occurs. 其中,所述基准值的第一上限指的是该基准值加上第一变化量所得的值,所述基准值的第一下限指的是该基准值减去第一变化量所得的值,所述基准值的第二上限指的是该基准值加上第二变化量所得的值,所述基准值的第二下限指的是该基准值减去第二变化量所得的值。 Wherein the first upper limit reference value refers to a value obtained by adding the reference value of the first variation, the first lower limit reference value refers to a value obtained by subtracting the reference value obtained in the first variation amount, the second upper limit reference value refers to a value obtained by adding the reference value of the second variation, the second lower limit reference value refers to a value obtained by subtracting the reference value of the second variation amount. 在实际应用中,所述基准值、第一变化量、第二变化量均可根据经验或每个使用者的具体情况进行设定。 In a practical application, the reference value, a first variation, a second variation amount can be set according to experience or particular circumstances of each user. 当然所述基准值还可采用动态基准值,即,以一定时间段内的合加速平均值作为基准值,例如,可以当前时刻的前2秒内所有加速度的平均值作为动态基准值,在实际应用中,可根据具体需要设定相应的时间。 Of course, the reference value may also be dynamic reference value, i.e., a certain time period in order to accelerate the closing of the average value as a reference value, for example, an average value of acceleration within all 2 seconds before the current time as a dynamic reference value, the actual applications, may be set according to specific needs the corresponding time.

[0077] 在实际应用中,为了更准确计量运动步数,步骤S2还包括下述步骤:判断当前波峰的时间间隔和当前波谷的时间间隔是否处于设定时间范围内,如果是,则判定当前波峰和波谷有效,反之则判定当前波峰和波谷无效。 [0077] In practice, in order to more accurately measure the number of movement steps, further comprising the step S2 following the step of: determining whether the current time interval and the peak current trough interval is within a predetermined time range, if yes, determines that the current peaks and troughs valid, otherwise it is determined that the current peaks and troughs invalid. 其中,所述当前波峰的时间间隔为加速度从所述基准值的第一上限到所述基准值的第一下限的时间间隔;所述当前波谷的时间间隔为加速度从所述基准值的第二下限到所述基准值第二上限的时间间隔。 Wherein the current peak time interval from a first interval value to the upper limit of the reference time of the first lower limit value of the reference acceleration; trough of the current time interval from the reference value for the acceleration of a second the lower limit to the upper limit value of the second time of the reference interval. 此处的设定时间间隔为根据经验及具体情况设定的一个时间范围,其与使用者完成一步所需时间有关,可根据使用者的身体状况、年龄进行设定或者采用一个较普遍的统计值。 Set time interval here is based on a time range of experience and the specific circumstances set with the user time to complete the steps necessary to related, according to the user's physical condition, age or adopt a set of more general statistics value. 因此,若当前波峰的时间间隔和当前波谷的时间间隔不处于设定时间范围内,则表示该波峰波谷不代表实际完成了一步,为干扰信号或噪声,可以排出,通过该步骤可以使计量步数更准确。 Thus, if the current time interval and the peak current is not within the troughs of the set time interval range, it indicates that the peaks and valleys do not represent the actual completion of the step, an interference signal or noise, can be discharged, it can be made step by step measurement the number is more accurate.

[0078] 进一步地,为了更准确的计量运动步数,步骤S3还包括下述步骤:判断当前波峰波谷与前一波峰波谷的时间间隔是否处于设定时间间隔内,若是,则使表征运动步数的计数值加I ;反之则判断当前连续行走步数是否小于设定值,即,当前连续出现的满足设定时间间隔的波峰波谷个数是否小于设定值,若是,则使计数清零并重新计数,反之则使表征运动步数的计数值加I。 [0078] Furthermore, for more accurate measurement of the number of movement steps, the step S3 further comprising the steps of: determining the current peaks and valleys and the crests and troughs of the previous time interval is within a predetermined time interval, and if yes, step motion so characterized count value plus I; otherwise determines whether the current step number continuously traveling than the set value, i.e., set to meet the current number of consecutive peaks and valleys of the time interval is less than a set value, if yes, the count is cleared and re-counting, the count value otherwise characterize movement plus the number of steps of I. 此处的设定时间间隔为正常行走和跑步时相邻两步的时间间隔,例如0.3秒至1.8秒,如果相邻两步的时间间隔不在此范围内,则表示这两步不是连续行走状态下的相邻两步,此时通过判断已经连续行走的步数可排除计步初始阶段的误差或者仅计量超过一定数量的连续行走步数。 Adjacent to the two-step interval set time interval is here the normal walking and running, for example 0.3 to 1.8 seconds, if the interval between consecutive two steps is not within this range, it indicates that these two steps are not continuous walking state adjacent two steps at this time is determined by the number of consecutive steps walking step count error can be excluded or only the initial stage of continuous measurement over a number of many steps. 例如为了排除计步初始阶段的误差,该设定值可设置为4-10步,当出现相邻两步的时间间隔不处于设定间隔范围内时,如果连续行走步数小于该设定值,则表示该连续行走步数为误差出现的步数,不代表实际行走步数,需要清零并重新计步。 For example in order to exclude the error count step of the initial stage, the setting value can be set to step 4-10, when there is an adjacent two-step interval is not within the range of the set interval, if the continuous many steps than the value , it indicates that the continuous walk step number of the step number error occurs, it does not represent the actual number of walking steps, and need to be cleared again pedometer.
