量測裝置及量測方法Measuring device and measuring method

本揭露內容是有關於一種量測裝置及量測方法。The content of this disclosure relates to a measuring device and a measuring method.

由於飲食與生活習慣的改變，慢性疾病已成為當前醫學領域的關注焦點。對此，由於慢性疾病無法根治，故目前應對方式為早期發現，以避免病情加重。慢性疾病包含像是高血壓、高血脂、心臟病、及糖尿病等。以糖尿病來說，其屬於一種代謝疾病，症狀為患者的血糖會長期高於標準值。因此，糖尿病的患者常需要自行檢測血糖濃度，從而經由檢驗來得知血糖濃度的高低，藉此控制飲食並維持血糖濃度。Due to changes in diet and living habits, chronic diseases have become the focus of attention in the current medical field. In this regard, since chronic diseases cannot be cured, the current response method is early detection to avoid aggravation of the disease. Chronic diseases include high blood pressure, hyperlipidemia, heart disease, and diabetes. In the case of diabetes, it is a metabolic disease, and the symptom is that the patient's blood sugar will be higher than the standard value for a long time. Therefore, diabetic patients often need to detect the blood glucose concentration by themselves, so as to know the level of the blood glucose concentration through the test, so as to control the diet and maintain the blood glucose concentration.

隨著科技發展，醫學領域對疾病的檢測能力也隨之提升，像是可使用非侵入式的量測方式來得到血糖濃度。然而，在使用非侵入式的量測方式的過程中，受測目標將可能因發生移動或抖動而干擾到量測結果。因此，如何讓非侵入式的量測方式能更精確地得到受測目標的血糖濃度，已成為相關領域的研究發展方向之一。With the development of science and technology, the medical field's ability to detect diseases has also improved, such as non-invasive measurement methods can be used to obtain blood glucose concentration. However, in the process of using non-intrusive measurement methods, the measured target may interfere with the measurement result due to movement or jitter. Therefore, how to make non-invasive measurement methods to obtain the blood glucose concentration of the tested target more accurately has become one of the research development directions in related fields.

第一加速度感測器120與第二加速度感測器122的設置位置非彼此相對。具體來說，第一加速度感測器120至第一表面S1的垂直投影與第二加速度感測器122至第一表面S1的垂直投影會是相分離的。透過如此配置，當遭遇受測者的抖動行為時，會因第一加速度感測器120與第二加速度感測器122的設置位置差異，而導致其與受測者的手指10發生抖動源頭處的距離不同，從而測得不同的加速度數值，以利做為判斷受測者是否發生抖動的依據。The installation positions of the first acceleration sensor 120 and the second acceleration sensor 122 are not opposite to each other. Specifically, the vertical projection of the first acceleration sensor 120 to the first surface S1 and the vertical projection of the second acceleration sensor 122 to the first surface S1 are separated. Through this configuration, when encountering the subject’s jitter behavior, the difference between the location of the first acceleration sensor 120 and the second acceleration sensor 122 will cause the subject’s finger 10 to shake at the source. The distance is different, so that different acceleration values are measured, which can be used as a basis for judging whether the subject is shaking.

第二加速度感測器122與第三加速度感測器124的設置位置可彼此相對。具體來說，第二加速度感測器122至第一表面S1的垂直投影係與第三加速度感測器124至第一表面S1的垂直投影至少部分重疊或是完全重合。如此配置可使第二加速度感測器122與第三加速度感測器124在感測加速度數值時，會具有接近的參數條件，並因此第二加速度感測器122與第三加速度感測器124測得的加速度數值可適於做為判斷受測者動作的輔助依據。The installation positions of the second acceleration sensor 122 and the third acceleration sensor 124 may be opposite to each other. Specifically, the vertical projection of the second acceleration sensor 122 to the first surface S1 and the vertical projection of the third acceleration sensor 124 to the first surface S1 at least partially overlap or completely overlap. Such a configuration allows the second acceleration sensor 122 and the third acceleration sensor 124 to have similar parameter conditions when sensing acceleration values, and therefore the second acceleration sensor 122 and the third acceleration sensor 124 The measured acceleration value can be used as an auxiliary basis for judging the action of the subject.

此外，第一加速度感測器120與第一表面S1之間的垂直距離可實質上等於第三加速度感測器124與第一表面S1之間的垂直距離，例如其可貼齊第一表面S1或是皆與第一表面S1相隔一段相同間距。如此配置可使第一加速度感測器120與第三加速度感測器124在感測加速度數值時，會具有接近的參數條件，並因此第一加速度感測器120與第三加速度感測器124測得的加速度數值可適於做為判斷受測者動作的輔助依據。In addition, the vertical distance between the first acceleration sensor 120 and the first surface S1 may be substantially equal to the vertical distance between the third acceleration sensor 124 and the first surface S1, for example, it may be aligned with the first surface S1 Or they are all separated from the first surface S1 by the same distance. Such a configuration allows the first acceleration sensor 120 and the third acceleration sensor 124 to have similar parameter conditions when sensing acceleration values, and therefore the first acceleration sensor 120 and the third acceleration sensor 124 The measured acceleration value can be used as an auxiliary basis for judging the action of the subject.

以下將對判斷受測者的動作做進一步的說明，請看到第2圖，第2圖為依據本揭露內容的第一實施方式繪示使用量測裝置進行量測方法的流程圖。如第2圖所示，量測方法包含步驟S10、S20、S30、S40、S50、S60、S70、S80、S90、S100及S110。步驟S10為感速加速度。步驟S20為計算出第一比值，並比較第一比值與第一判斷條件值之關係。步驟S30為比較第一比值與第二判斷條件值之關係。步驟S40為判斷為雜訊。步驟S50為進行判斷條件式的運算。步驟S60為修正光感測器之光強度數值。步驟S70為計算出第二比值。步驟S80為比較第二比值與判斷條件範圍之關係。步驟S90為判斷為雜訊。步驟S100為修正光感測器之光強度數值。步驟S110為輸出光感測器之光強度數值。The following will further explain the action of judging the subject. Please see FIG. 2. FIG. 2 is a flowchart of a measurement method using a measurement device according to the first embodiment of the present disclosure. As shown in Figure 2, the measurement method includes steps S10, S20, S30, S40, S50, S60, S70, S80, S90, S100, and S110. Step S10 is the speed sensing acceleration. Step S20 is to calculate the first ratio and compare the relationship between the first ratio and the first judgment condition value. Step S30 is to compare the relationship between the first ratio and the second judgment condition value. Step S40 is to determine that it is noise. Step S50 is to perform the calculation of the judgment condition formula. Step S60 is to correct the light intensity value of the light sensor. Step S70 is to calculate the second ratio. Step S80 is to compare the relationship between the second ratio and the judgment condition range. Step S90 is to determine that it is noise. Step S100 is to correct the light intensity value of the light sensor. Step S110 is to output the light intensity value of the light sensor.

前述所提之量測受測者的光學訊號與第2圖所示的各步驟可同步進行。換言之，在進行步驟S10至步驟S110的同時，光發射器會持續地發出光束照射受測者的手指，且光感測器也會持續地接收自受測者的手指離開之光束，從而將對應光束之光強度數值傳輸至控制器。The aforementioned measurement of the optical signal of the subject and the steps shown in Figure 2 can be performed simultaneously. In other words, while performing step S10 to step S110, the light transmitter will continuously emit a light beam to illuminate the subject’s finger, and the light sensor will also continue to receive the light beam leaving from the subject’s finger, thereby corresponding The light intensity value of the beam is transmitted to the controller.

於步驟S10中，各加速度感測器會開始記錄測得的加速度數值，並將測得的加速度數值傳輸至控制器，其中各加速度感測器記錄加速度數值的頻率為每秒10筆(即每0.1秒可產生一筆加速度數值)。In step S10, each acceleration sensor will start to record the measured acceleration value and transmit the measured acceleration value to the controller. The frequency of each acceleration sensor recording the acceleration value is 10 pens per second (that is, every An acceleration value can be generated in 0.1 second).

以下關於步驟S20至步驟S60的說明中，將是以第一加速度感測器測得的加速度數值進行處理做為範例來說明，而這些數據處理方式同樣可套用至第二加速度感測器或第三加速度感測器所測得的加速度數值。為了方便說明，第一加速度感測器測得的加速度數值將以數值Gn 表示，例如第一筆加速度數值可表示為數值G1 ，而第二筆加速度數值可表示為數值G2 。在此所述的第一筆加速度數值與第二筆加速度數值指的是第一加速度感測器連續測得的兩筆加速度數值，且其可以是相同軸向的加速度數值，例如數值G1 及G2 可皆為是第一加速度感測器在x軸向上於不同時間點測得的加速度數值。In the following description of steps S20 to S60, the acceleration value measured by the first acceleration sensor is used as an example for description, and these data processing methods can also be applied to the second acceleration sensor or the first acceleration sensor. Acceleration value measured by three acceleration sensors. For the convenience of description, the acceleration value measured by the first acceleration sensor will be represented by a value G n . For example, the first acceleration value can be represented as a value G 1 , and the second acceleration value can be represented as a value G 2 . The first acceleration value and the second acceleration value mentioned here refer to the two acceleration values continuously measured by the first acceleration sensor, and they can be acceleration values in the same axis, such as the values G 1 and G 2 can all be the acceleration values measured by the first acceleration sensor at different time points along the x-axis.

於步驟S20中，在第一加速度感測器測得加速度數值之期間，控制器可用以計算第一加速度感測器在連續的第一時序及第二時序的加速度數值之比值，以得到第一比值。具體來說，控制器可持續計算(Gn+1 /Gn )的數值，並將此數值記錄為第一比值，例如先計算(G2 /G1 )的數值，並接著再計算(G3 /G2 )的數值。第一加速度感測器測得加速度數值與控制器計算第一比值可以是同步進行。因此，自第一加速度感測器測得數值G1 後，隨著第一加速度感測器每測出一筆新的加速度數值，控制器即對應地計算出一個新的第一比值。In step S20, during the period when the first acceleration sensor measures the acceleration value, the controller can calculate the ratio of the acceleration value of the first acceleration sensor in the continuous first time sequence and the second time sequence to obtain the first acceleration value. One ratio. Specifically, the controller can continuously calculate the value of (G n+1 /G n ) and record this value as the first ratio. For example, first calculate the value of (G 2 /G 1 ), and then calculate (G 3 /G 2 ). The acceleration value measured by the first acceleration sensor and the first ratio calculated by the controller may be performed synchronously. Thus, from the first measured value after the acceleration sensor G 1, as a first acceleration sensor for each measured value by a new, acceleration, i.e., the controller calculates a first ratio corresponding to the new.

請一併看到第3圖，第3圖為第一比值與時間的關係圖。第3圖所示的圖形表示了由控制器計算出的第一比值與相對應時間點的關係圖。第3圖中，橫軸為時間且單位為秒，而縱軸為加速度數值之比值且為無單位。控制器會隨著時間持續計算出對應每一個時間點的第一比值，接著，控制器會比較計算出的第一比值與第一判斷條件值之關係，其中第一判斷條件值可以是在量測方法進行前先設定。例如，第一判斷條件值可以具有上限數值「2」且下限數值「-2」，其在第3圖的位置可如虛線L1或L2所示。每當控制器計算出一筆第一比值時，即會進行比較第一比值與第一判斷條件值之關係。對此，當第一比值落於第一判斷條件值之內時(即-2≦Gn+1 /Gn ≦2)，即判斷第一比值符合第一判斷條件值。反之，當第一比值落於第一判斷條件值之外時(即Gn+1 /Gn ＜-2或Gn+1 /Gn ＞2)，即判斷第一比值未符合第一判斷條件值。Please also see Figure 3, which is the relationship between the first ratio and time. The graph shown in Figure 3 shows the relationship between the first ratio calculated by the controller and the corresponding time point. In Figure 3, the horizontal axis is time and the unit is seconds, and the vertical axis is the ratio of acceleration values and is unitless. The controller will continue to calculate the first ratio corresponding to each time point over time, and then the controller will compare the calculated first ratio with the first judgment condition value, where the first judgment condition value can be a quantity Set the measurement method before proceeding. For example, the first judgment condition value may have an upper limit value "2" and a lower limit value "-2", and its position in FIG. 3 may be as shown by the dashed line L1 or L2. Whenever the controller calculates a first ratio, it will compare the relationship between the first ratio and the first judgment condition value. In this regard, when the first ratio falls within the first judgment condition value (that is, -2≦G n+1 /G n ≦2), it is judged that the first ratio meets the first judgment condition value. Conversely, when the first ratio falls outside the first judgment condition value (ie G n+1 /G n <-2 or G n+1 /G n ＞2), it is judged that the first ratio does not meet the first judgment Condition value.

判斷第一比值是否符合第一判斷條件值可視為判斷受測者的手指有無在量測光學訊號中發生移動行為，例如上下移動。當第一比值未符合第一判斷條件值的情況持續連續1秒(或以上)的時候，即判斷受測者的手指有上下移動行為，並進入步驟S30。舉例來說，在第3圖的第一時間點T1(或接近第一時間點T1)時，控制器會判斷受測者的手指有上下移動行為，並因此進入步驟S30。反之，若判斷受測者的手指未有上下移動行為，則進入步驟S70。Determining whether the first ratio meets the first judging condition value can be regarded as judging whether the subject's finger moves in the measured optical signal, such as moving up and down. When the situation that the first ratio does not meet the first judgment condition value continues for 1 second (or more), that is, it is judged that the subject's finger is moving up and down, and step S30 is entered. For example, at the first time point T1 (or close to the first time point T1) in FIG. 3, the controller will determine that the subject's finger moves up and down, and therefore enter step S30. Conversely, if it is determined that the subject's finger does not move up and down, then step S70 is entered.

於步驟S30中，控制器會進一步比較步驟S20計算出的第一比值與第二判斷條件值之關係，其中第二判斷條件值可以是在量測方法進行前先設定。例如，第二判斷條件值可以具有上限數值「5」且下限數值「-5」，其在第3圖的位置可如虛線L3或L4所示。同樣地，每當控制器計算出一筆第一比值且第一比值未符合第一判斷條件值時，即會進行比較第一比值與第二判斷條件值之關係。In step S30, the controller further compares the relationship between the first ratio calculated in step S20 and the second judgment condition value, where the second judgment condition value may be set before the measurement method is performed. For example, the second judgment condition value may have an upper limit value of "5" and a lower limit value of "-5", and its position in FIG. 3 may be as shown by the dashed line L3 or L4. Similarly, whenever the controller calculates a first ratio and the first ratio does not meet the first judgment condition value, it will compare the relationship between the first ratio and the second judgment condition value.

對此，當第一比值落於第一判斷條件值之外且落於第二判斷條件值之內時(即-5≦Gn+1 /Gn ＜-2或2＜Gn+1 /Gn ≦5)，即可接著判斷第一比值是否符合接續的判斷條件式。反之，當第一比值落於第二判斷條件值之外(即Gn+1 /Gn ＜-5或Gn+1 /Gn ＞5)，即判斷第一比值未符合第二判斷條件值。In this regard, when the first ratio falls outside the first judgment condition value and falls within the second judgment condition value (that is, -5≦G n+1 /G n ≦-2 or 2≦G n+1 / G n ≦5), then it can be judged whether the first ratio meets the connection judgment condition formula. Conversely, when the first ratio falls outside the second judgment condition value (ie G n+1 /G n <-5 or G n+1 /G n ＞5), it is judged that the first ratio does not meet the second judgment condition value.

當第一比值未符合第二判斷條件值的時候，即進入步驟S40。當第一比值符合第二判斷條件值的時候，即進入步驟S50。此外，於判斷受測者的手指有上下移動行為後，若Gn+1 /Gn 之值在連續2秒(或以上)的期間符合-2≦Gn+1 /Gn ≦2時，則判斷受測者的移動行為中止，並進入步驟S70。When the first ratio does not meet the second judgment condition value, step S40 is entered. When the first ratio meets the second judgment condition value, step S50 is entered. In addition, after judging that the subject’s finger is moving up and down, if the value of G n+1 /G n meets -2≦G n+1 /G n ≦2 for a continuous period of 2 seconds (or more), Then it is judged that the movement behavior of the subject is suspended, and step S70 is entered.

於步驟S40中，可因第一比值未符合第二判斷條件值，而判斷此時受測者的手指的移動行為過度劇烈，並對應地捨棄所記錄的光強度數值，從而避免這些光強度數值影響到對受測者血糖濃度的量測結果。In step S40, because the first ratio does not meet the second judgment condition value, it is judged that the movement behavior of the subject's finger is excessively violent at this time, and the recorded light intensity values are discarded accordingly, so as to avoid these light intensity values Affect the measurement results of the subject's blood glucose concentration.

於步驟S50中，可因第一比值符合第二判斷條件值，而接著判斷第一比值是否符合判斷條件式。具體來說，由於前述判斷計算條件未對加速度方向所代表的正負號有進一步判斷，故計算出相同量值卻正負號不同時，會代表不同的移動程度。舉例來說，若Gn+1 /Gn =3或Gn+1 /Gn =-3，則分別表示「Gn+1 為Gn 的3倍」或是「Gn+1 為Gn 的(-3)倍」之狀況，而受測者的手指對此兩種狀況係為不同的移動程度。更詳細而言，「Gn+1 為Gn 的(-3)倍」所代表的單位時間移動程度會是大於「Gn+1 為Gn 的3倍」所代表的單位時間移動程度。In step S50, since the first ratio meets the second judgment condition value, it is then judged whether the first ratio meets the judgment condition formula. Specifically, since the aforementioned judgment calculation conditions do not further judge the sign of the acceleration direction, when the same magnitude is calculated but the sign is different, it will represent a different degree of movement. For example, if G n + 1 / G n = 3 or G n + 1 / G n = -3, respectively represent "G n + 1 to 3 times the G n" or "G n + 1 to G (-3) times of n ”, and the testee’s fingers have different degrees of movement in these two situations. More specifically, the degree of movement per unit time represented by "G n + 1 to G n of the (-3) times" would be greater than the "G n + 1 to 3 times the G n" the degree of movement per unit time is represented.

對此，若第一比值為正值時，則進入步驟S60，而若第一比值為負值時，則對第一比值進行判斷條件式之運算，其中判斷條件式為：「(Gn+1 /Gn )-1」。判斷條件式可由(Gn+1 -Gn )/Gn 經整理後而得，此式子的物理意義為：當Gn+1 與Gn 為異號時，(Gn+1 -Gn )計算出的結果量值會大於Gn+1 與Gn 各自的量值，並可視為Gn+1 與Gn 之間的差異。接著，再比較判斷條件式的運算結果與第二判斷條件值之關係。在運算結果落於第一判斷條件值之外且落於第二判斷條件值之內時(即(Gn+1 -Gn )/Gn 為負且-5≦Gn+1 /Gn ＜-2，即進入步驟S60。反之，當運算結果落於第二判斷條件值之外時(即(Gn+1 -Gn )/Gn 為負且(Gn+1 -Gn )/Gn ＜-5)，即判斷未通過判斷條件式，並進入步驟S40。In this regard, if the first ratio is a positive value, then go to step S60, and if the first ratio is a negative value, then the first ratio is subjected to the calculation of the judgment condition formula, where the judgment condition formula is: "(G n+ 1 /G n )-1". The judgment condition formula can be obtained by sorting (G n+1 -G n )/G n . The physical meaning of this formula is: when G n+1 and G n are different signs, (G n+1 -G n) calculated result will be greater than the magnitude G n + 1 and G n respective magnitudes, and regarded as the difference between G n + 1 and G n. Then, compare the relationship between the calculation result of the judgment condition formula and the second judgment condition value. When the calculation result falls outside the first judgment condition value and falls within the second judgment condition value (that is, (G n+1 -G n )/G n is negative and -5≦G n+1 /G n <-2, that is, go to step S60. On the contrary, when the calculation result falls outside the second judgment condition value (ie (G n+1 -G n )/G n is negative and (G n+1 -G n ) /G n <-5), that is, it is judged that the judgment condition formula is not passed, and the process proceeds to step S40.

於步驟S60中，可因第一比值符合前述的判斷過程，而判斷此時受測者的手指的移動行為係可接受的。此時，控制器會修正光感測器之光強度數值，以對光感測器之感測結果進行補償。對此，修正光感測器之光強度數值的步驟包含計算光感測器之光強度數值與光強度樣本值之平均值。光強度樣本值可以是判斷受測者未發生移動行為時所記錄的光強度數值，或是判斷受測者未發生移動行為期間所記錄的光強度數值之平均值。舉例來說，可在第3圖的第一時間點T1之前，取所記錄的多個光強度數值的其中一筆做為光強度樣本值，或者，也可以是將第3圖的第一時間點T1之前記錄的全部光強度數值取平均做為光強度樣本值。In step S60, it can be judged that the movement behavior of the subject's finger at this time is acceptable because the first ratio conforms to the aforementioned judgment process. At this time, the controller will correct the light intensity value of the light sensor to compensate the sensing result of the light sensor. In this regard, the step of correcting the light intensity value of the light sensor includes calculating the average value of the light intensity value of the light sensor and the light intensity sample value. The light intensity sample value can be the light intensity value recorded when it is judged that the subject is not moving, or the average value of the light intensity value recorded during the judging that the subject is not moving. For example, before the first time point T1 in Figure 3, one of the multiple recorded light intensity values can be taken as the light intensity sample value, or it can be the first time point in Figure 3 All the light intensity values recorded before T1 are averaged as the light intensity sample value.

在第一時間點T1之後，若發生第一比值大於第一判斷條件值且符合第二判斷條件值時(即符合步驟S30及步驟S50的判斷內容)發生，則控制器可對應發生的時間點，修正此時間點所記錄之光強度數值。亦即，控制器可取此時間點所記錄之光強度數值與光強度樣本值之平均值，並將計算所得的平均值取代此時間點原本測得的光強度數值。如此一來，即完成對光感測器之感測結果的補償，從而避免因受測者的移動行為造成光感測器之感測結果失真，並接著進入步驟S110。After the first time point T1, if the first ratio is greater than the first judgment condition value and meets the second judgment condition value (that is, the judgment content of step S30 and step S50 is met), the controller can correspond to the time point of occurrence , Revise the light intensity value recorded at this point in time. That is, the controller can take the average value of the light intensity value recorded at this time point and the light intensity sample value, and replace the originally measured light intensity value at this time point with the calculated average value. In this way, the compensation of the sensing result of the light sensor is completed, so as to prevent the sensing result of the light sensor from being distorted due to the movement behavior of the subject, and then step S110 is performed.

同前於步驟S10所述，若判斷受測者的手指未有上下移動行為，則進入步驟S70。以下關於步驟S70至步驟S100的說明中，將是以第一加速度感測器與第二加速度感測器測得的加速度數值進行處理做為範例來說明，而這些數據處理方式同樣可套用至其他加速度感測器之組合(例如第一加速度感測器與第三加速度感測器)所測得的加速度數值。為了方便說明，第一加速度數值測得的加速度數值將以數值GA表示，而第二加速度數值測得的加速度數值將以數值GB表示，其中數值GA與數值GB可以是在同一個時間點測得，且其可以是相同軸向的加速度數值。Same as described in step S10, if it is determined that the subject's finger does not move up and down, then step S70 is entered. In the following description of steps S70 to S100, the acceleration values measured by the first acceleration sensor and the second acceleration sensor are processed as an example, and these data processing methods can also be applied to other data processing methods. The acceleration value measured by the combination of acceleration sensors (for example, the first acceleration sensor and the third acceleration sensor). For the convenience of explanation, the acceleration value measured by the first acceleration value will be represented by the value GA, and the acceleration value measured by the second acceleration value will be represented by the value GB, where the value GA and the value GB can be measured at the same time point , And it can be the acceleration value in the same axial direction.

於步驟S70中，控制器可用以計算第一加速度感測器與第二加速度感測器在第一時序或第二時序的加速度數值之比值，以得到第二比值。具體來說，控制器可持續計算每一個時間點的|GA/GB|的數值，並將此數值記錄為第二比值，例如先計算時間點為1秒時的資料點之|GA/GB|的數值，並接著再計算時間點為1秒時的下一個資料點之|GA/GB|的數值。各加速度感測器測得加速度數值與控制器計算第二比值可以是同步進行。因此，自各加速度感測器測得加速度數值後，隨著各加速度感測器每測出一筆新的加速度數值，控制器即對應地計算出一個新的第二比值，並進入步驟S80。In step S70, the controller can calculate the ratio of the acceleration values of the first acceleration sensor and the second acceleration sensor in the first time sequence or the second time sequence to obtain the second ratio. Specifically, the controller can continuously calculate the value of |GA/GB| at each time point and record this value as the second ratio. For example, first calculate the value of |GA/GB| for the data point when the time point is 1 second. Then calculate the value of |GA/GB| of the next data point when the time point is 1 second. The acceleration value measured by each acceleration sensor and the second ratio calculated by the controller may be performed synchronously. Therefore, after the acceleration values are measured by each acceleration sensor, as each acceleration sensor measures a new acceleration value, the controller correspondingly calculates a new second ratio and enters step S80.

請一併看到第4圖，第4圖為第二比值與時間的關係圖。第4圖所示的圖形表示了由控制器計算出的第二比值與相對應時間點的關係圖。第4圖中，橫軸為時間且單位為秒，而縱軸為加速度數值之比值且為無單位。於步驟S80中，控制器會比較計算出的第二比值與判斷條件範圍之關係，其中判斷條件範圍可以是在量測方法進行前先設定。例如，判斷條件範圍可分為三個區間，稱第一區間、第二區間以及第三區間。第一區間可以是大於等於0.95且小於等於1.05，如第4圖的區間I1所示；第二區間可以是超過0.8且未達0.95或者是超過1.05且未達1.20，如第4圖的區間I2A及I2B所示；第三區間可以是小於等於0.8或者是大於等於1.2，如第4圖的區間I3A及I3B所示。每當控制器計算出一筆第二比值時，即會進行比較第二比值與判斷條件範圍之關係。對此，當第二比值落於第一區間時(即0.95≦|GA/GB|≦1.05，如區間I1所示)，即判斷第二比值符合判斷條件範圍。反之，當第二比值非落於第一區間時，即判斷第二比值未符合判斷條件範圍，此時，接著再判斷此第二比值是落在第二區間(即0.85＜|GA/GB|＜0.95或是1.05＜|GA/GB|＜1.20，如區間I2A或I2B所示)或第三區間(即|GA/GB|≦0.8或是|GA/GB|≧1.2，如區間I3A或I3B所示)。Please also see Figure 4, which shows the relationship between the second ratio and time. The graph shown in Figure 4 shows the relationship between the second ratio calculated by the controller and the corresponding time point. In Figure 4, the horizontal axis is time and the unit is seconds, and the vertical axis is the ratio of acceleration values and is unitless. In step S80, the controller compares the relationship between the calculated second ratio and the judgment condition range, where the judgment condition range can be set before the measurement method is performed. For example, the judgment condition range can be divided into three intervals, called the first interval, the second interval, and the third interval. The first interval can be greater than or equal to 0.95 and less than or equal to 1.05, as shown in the interval I1 in Figure 4; the second interval can be more than 0.8 and less than 0.95 or more than 1.05 and less than 1.20, as shown in the interval I2A in Figure 4 And I2B; the third interval can be less than or equal to 0.8 or greater than or equal to 1.2, as shown in the intervals I3A and I3B in Figure 4. Whenever the controller calculates a second ratio, it will compare the relationship between the second ratio and the judgment condition range. In this regard, when the second ratio falls within the first interval (ie, 0.95≦|GA/GB|≦1.05, as shown in the interval I1), it is determined that the second ratio meets the judgment condition range. Conversely, when the second ratio does not fall in the first interval, it is judged that the second ratio does not meet the judgment condition range. At this time, it is then judged that the second ratio falls in the second interval (ie 0.85<|GA/GB| ＜0.95 or 1.05＜|GA/GB|＜1.20, as shown in the interval I2A or I2B) or the third interval (ie |GA/GB|≦0.8 or |GA/GB|≧1.2, as in the interval I3A or I3B Shown).

判斷第二比值是否符合判斷條件範圍可視為判斷受測者有無在量測光學訊號中發生抖動行為。進一步來說，第二比值與抖動行為的劇烈程度有相關性，當第二比值越大時，即表示有較劇烈的抖動行為；反之，當二比值越小時，即表示抖動行為較緩和或是趨近未發生抖動行為。Determining whether the second ratio meets the judgment condition range can be regarded as judging whether the subject has jittered in the measured optical signal. Furthermore, the second ratio is related to the severity of the jittering behavior. When the second ratio is larger, it means that there is a more violent jittering behavior; conversely, when the second ratio is smaller, it means that the jittering behavior is more moderate or There is no jitter behavior when approaching.

當第二比值未符合判斷條件範圍，且第二比值落於第三區間(即區間I3A或I3B)時，會進入步驟S90，而當第二比值未符合判斷條件範圍，且第二比值落於第二區間時(即區間I2A或I2B)，會進入步驟S100。舉例來說，在第4圖的第二時間點T2之後，控制器判斷受測者有發生抖動行為，並會進入步驟S90或步驟S100。反之，若判斷未發生抖動，則進入步驟S110。When the second ratio does not meet the judgment condition range and the second ratio falls within the third interval (ie, interval I3A or I3B), step S90 is entered, and when the second ratio does not meet the judgment condition range, and the second ratio falls within In the second interval (ie, interval I2A or I2B), step S100 is entered. For example, after the second time point T2 in FIG. 4, the controller determines that the subject has a jitter behavior, and will enter step S90 or step S100. Conversely, if it is determined that no jitter has occurred, the process proceeds to step S110.

於步驟S90中，可因第二比值未符合判斷條件範圍，且第二比值落於第三區間，而判斷此時受測者的抖動行為過度劇烈，並對應地捨棄所記錄的光強度數值，從而避免這些光強度數值影響到對受測者血糖濃度的量測結果。In step S90, because the second ratio does not meet the judgment condition range and the second ratio falls within the third interval, it is judged that the subject’s jitter behavior is excessively severe at this time, and the recorded light intensity value is discarded accordingly. This prevents these light intensity values from affecting the measurement results of the subject's blood glucose concentration.

於步驟S100中，可因第二比值落於第二區間，而判斷此時受測者的手指的抖動行為係可接受的。此時，控制器會修正光感測器之光強度數值，以對光感測器之感測結果進行補償。對此，修正光感測器之光強度數值的步驟包含計算光感測器之光強度數值與光強度樣本值之平均值。此光強度樣本值的定義可同前述。舉例來說，可在第4圖的第二時間點T2之前，取所記錄的多個光強度數值的其中一筆做為光強度樣本值，或者，也可以是將第4圖的第二時間點T2之前記錄的全部光強度數值取平均做為光強度樣本值。In step S100, because the second ratio falls within the second interval, it can be determined that the shaking behavior of the subject's finger at this time is acceptable. At this time, the controller will correct the light intensity value of the light sensor to compensate the sensing result of the light sensor. In this regard, the step of correcting the light intensity value of the light sensor includes calculating the average value of the light intensity value of the light sensor and the light intensity sample value. The definition of the light intensity sample value can be the same as that described above. For example, before the second time point T2 in Figure 4, one of the multiple recorded light intensity values can be taken as the light intensity sample value, or it can be the second time point in Figure 4 All the light intensity values recorded before T2 are averaged as the light intensity sample value.

在第二時間點T2之後，若發生第二比值未符合判斷條件範圍，且第二比值落於第二區間時(即0.85＜|GA/GB|＜0.95或是1.05＜|GA/GB|＜1.20，如區間I2A或I2B所示)發生，則控制器可對應發生的時間點，修正此時間點所記錄之光強度數值。亦即，控制器可取此時間點所記錄之光強度數值與光強度樣本值之平均值，並將計算所得的平均值取代此時間點原本測得的光強度數值。如此一來，即完成對光感測器之感測結果的補償，從而避免因受測者的移動行為造成光感測器之感測結果失真，並接著進入步驟S110。After the second time point T2, if the second ratio does not meet the judgment condition range and the second ratio falls within the second interval (ie 0.85＜|GA/GB|＜0.95 or 1.05＜|GA/GB|＜ 1.20, as shown in the interval I2A or I2B) occurs, the controller can correct the light intensity value recorded at this time point corresponding to the time point of occurrence. That is, the controller can take the average value of the light intensity value recorded at this time point and the light intensity sample value, and replace the originally measured light intensity value at this time point with the calculated average value. In this way, the compensation of the sensing result of the light sensor is completed, so as to prevent the sensing result of the light sensor from being distorted due to the movement behavior of the subject, and then step S110 is performed.

步驟S110中，控制器會輸出透過光感測器測得的光強度數值，並將光強度數值匯入至資料庫，以利進行後續之比對受測者的血糖濃度。對此，若因符合前述條件而判斷受測者的手指未有移動或抖動行為時，則控制器可直接輸出光感測器之光強度數值至資料庫。相反地，若因未符合前述條件而判斷受測者的手指有移動或抖動行為，且有對光感測器之光強度數值做出修正時，則控制器將會輸出修正後的光感測器之光強度數值至資料庫。也就是說，本揭露內容的量測方法係使控制器可依據第一比值與第二比值輸出光感測器之感測結果，例如判斷是否修正光感測器之光強度數值，從而避免因受測者的動作造成光感測器之感測結果失真。In step S110, the controller outputs the light intensity value measured through the light sensor, and imports the light intensity value into the database to facilitate subsequent comparison of the blood glucose concentration of the subject. In this regard, if it is determined that the subject's finger does not move or shake because the aforementioned conditions are met, the controller can directly output the light intensity value of the light sensor to the database. Conversely, if it is determined that the subject’s finger is moving or shaking because the aforementioned conditions are not met, and the light intensity value of the light sensor is corrected, the controller will output the corrected light sensor The light intensity value of the device is sent to the database. In other words, the measurement method of the present disclosure enables the controller to output the sensing result of the light sensor according to the first ratio and the second ratio, for example, to determine whether to correct the light intensity value of the light sensor, so as to avoid The motion of the subject causes the sensing result of the light sensor to be distorted.

同前所述，一些步驟的處理方式可套用至其他的加速度感測器。然而，本揭露內容不以此為限，於其他實施方式中，一些步驟的處理方式可同步套用至超過一個加速度感測器。舉例來說，在步驟S20至步驟S60之中，控制器除了可藉由第一加速度感測器測得的加速度數值來計算出第一比值以外，尚可藉由第二加速度感測器測得的加速度數值來計算出第三比值，其中第三比值為第二加速度感測器在第一時序及第二時序的加速度數值之比值。接著，再依據第一比值與第三比值判斷是否修正光感測器之光強度數值，例如可對第一比值與第三比值分配權重後相加，以利進行判斷。As mentioned above, the processing methods of some steps can be applied to other acceleration sensors. However, the content of the present disclosure is not limited to this. In other embodiments, the processing method of some steps can be simultaneously applied to more than one acceleration sensor. For example, in step S20 to step S60, in addition to calculating the first ratio by the acceleration value measured by the first acceleration sensor, the controller can also use the second acceleration sensor to measure The third ratio is calculated from the acceleration value of, where the third ratio is the ratio of the acceleration value of the second acceleration sensor in the first time sequence and the second time sequence. Then, it is determined whether to correct the light intensity value of the light sensor according to the first ratio and the third ratio. For example, the first ratio and the third ratio can be weighted and added to facilitate the judgment.

除此之外，本揭露內容的量測裝置除可應用為指套以外，也可應用為攜帶式裝置，像是手錶。舉例來說，請看到第5圖，第5圖為依據本揭露內容之第二實施方式繪示量測裝置100B的側視示意圖。本實施方式與第一實施方式的至少一個差異在於，本實施方式的量測裝置100B至少省略了第二殼體(例如第1A圖的第二殼體104)，並更包含第一錶帶130及第二錶帶132。第一錶帶130及第二錶帶132分別連接至第一殼體102的相對兩邊緣，並可拆卸式地連接在一起，例如第二錶帶132可穿過透過扣環134後，與第一錶帶130連接在一起。In addition, the measuring device of the present disclosure can be applied to not only a finger sleeve, but also a portable device, such as a watch. For example, please see FIG. 5, which is a schematic side view of the measurement device 100B according to the second embodiment of the present disclosure. At least one difference between this embodiment and the first embodiment is that the measurement device 100B of this embodiment at least omits a second housing (for example, the second housing 104 in Figure 1A), and further includes a first strap 130 And the second strap 132. The first strap 130 and the second strap 132 are respectively connected to two opposite edges of the first housing 102 and can be detachably connected together. For example, the second strap 132 can pass through the through buckle 134 to connect with A strap 130 is connected together.

本實施方式中，第一加速度感測器120與第二加速度感測器122會共同設置於第一殼體102內，且第一加速度感測器120與第二加速度感測器122至第一表面S1的垂直距離相同。具體來說，第一加速度感測器120與第一表面S1之間的垂直距離可視為第一距離，而第二加速度感測器122與第一表面S1之間的垂直距離可視為第二距離，且第一距離實質上等於第二距離。舉例來說，例如第一加速度感測器120與第二加速度感測器122可貼齊第一表面S1，或者是皆與第一表面S1相隔一段相同間距。In this embodiment, the first acceleration sensor 120 and the second acceleration sensor 122 are jointly arranged in the first housing 102, and the first acceleration sensor 120 and the second acceleration sensor 122 are arranged in the first housing 102 together. The vertical distance of the surface S1 is the same. Specifically, the vertical distance between the first acceleration sensor 120 and the first surface S1 can be regarded as the first distance, and the vertical distance between the second acceleration sensor 122 and the first surface S1 can be regarded as the second distance , And the first distance is substantially equal to the second distance. For example, for example, the first acceleration sensor 120 and the second acceleration sensor 122 may be aligned with the first surface S1, or they may be separated from the first surface S1 by the same distance.

當進行對受測者的光學訊號量測時，光發射器110可朝著第一表面S1發出光束。光束可在進入受測者的手臂後發生反射，並因此行進至進入光感測器112的感測面S3，使得光感測器112可測得對應光束的光強度數值，並將光強度數值傳輸至控制器126。同時，第一加速度感測器120與第二加速度感測器122會將測得的加速度數值傳輸至控制器126，藉以進行如第3圖所繪的各步驟，從而判斷是否要修正光感測器之光強度數值，從而避免因受測者的動作造成光感測器之感測結果失真。When measuring the optical signal of the subject, the light emitter 110 can emit a light beam toward the first surface S1. The light beam can be reflected after entering the arm of the subject, and therefore travels to the sensing surface S3 of the light sensor 112, so that the light sensor 112 can measure the light intensity value of the corresponding light beam, and then calculate the light intensity value. Transmitted to the controller 126. At the same time, the first acceleration sensor 120 and the second acceleration sensor 122 will transmit the measured acceleration value to the controller 126 to perform the steps as depicted in Figure 3 to determine whether to correct the light sensing The light intensity value of the sensor, so as to avoid the distortion of the sensing result of the light sensor caused by the action of the subject.

請再看到第6圖，第6圖為依據本揭露內容之第三實施方式繪示量測裝置100C的側視示意圖。本實施方式與第一實施方式的至少一個差異在於，本實施方式的第一加速度感測器120與第二加速度感測器122至第一表面S1的垂直距離不同。具體來說，第一加速度感測器120與第一表面S1之間的垂直距離可視為第一距離，第二加速度感測器122與第一表面S1之間的垂直距離可視為第二距離，且第一距離實質上大於第二距離。如此的配置可使第一加速度感測器120與第二加速度感測器122在遭遇受測者的抖動行為時，能測得不同的加速度數值，以利判斷受測者是否發生抖動。Please see FIG. 6 again, which is a schematic side view of the measurement device 100C according to the third embodiment of the present disclosure. At least one difference between this embodiment and the first embodiment is that the vertical distances from the first acceleration sensor 120 and the second acceleration sensor 122 to the first surface S1 in this embodiment are different. Specifically, the vertical distance between the first acceleration sensor 120 and the first surface S1 can be regarded as the first distance, and the vertical distance between the second acceleration sensor 122 and the first surface S1 can be regarded as the second distance. And the first distance is substantially greater than the second distance. Such a configuration enables the first acceleration sensor 120 and the second acceleration sensor 122 to measure different acceleration values when encountering the subject's shaking behavior, so as to facilitate the determination of whether the subject is shaking.

綜上所述，本揭露內容的量測裝置包含第一加速度感測器、第二加速度感測器、光發射器、光感測器以及控制器。光發射器與光感測器可共同進行對受測者的光學訊號量測，並將感測結果傳輸至控制器，以利控制器藉由感測結果比對受測者的血糖濃度。第一加速度感測器與第二加速度感測器可測得加速度數值，並傳輸至控制器。控制器能對第一加速度感測器與第二加速度感測器測得的加速度數值進行處理，以判斷是否要修正光感測器之光強度數值，從而避免因受測者的動作造成光感測器之感測結果失真。In summary, the measurement device of the present disclosure includes a first acceleration sensor, a second acceleration sensor, a light emitter, a light sensor, and a controller. The light emitter and the light sensor can jointly measure the optical signal of the subject, and transmit the sensing result to the controller, so that the controller can compare the blood glucose concentration of the subject with the sensing result. The first acceleration sensor and the second acceleration sensor can measure the acceleration value and transmit it to the controller. The controller can process the acceleration values measured by the first acceleration sensor and the second acceleration sensor to determine whether to correct the light intensity value of the light sensor, so as to avoid the light sensing caused by the action of the subject The sensing result of the detector is distorted.
