Description
本發明係有關於量測裝置及方法，尤其更有關於用以量測心電圖的量測裝置及其量測方法。 The present invention relates to a measuring device and method, and more particularly to a measuring device for measuring an electrocardiogram and a measuring method thereof.
近年來，民眾對於安全驗證的需求逐漸提高，舉凡輸入個人密碼或身份ID、感應門禁卡或是生物特徵辨識等驗證方式，實已普及於日常生活當中。 In recent years, the demand for security verification has gradually increased, and the verification methods such as inputting personal passwords or identity IDs, sensory access cards, or biometric identification have become popular in daily life.
經過統計，一般大眾平均每天至少花費十四分鐘在使用行動電話，藉由一般大眾普遍持有行動電話的趨勢，本技術領域的技術人員紛紛提出了各種方案，希望能將使用者的驗證資訊與行動電話結合，藉此通過行動電話來進行驗證，進而便於使用者在驗證通過後直接進行小額消費或各項操作。 According to statistics, the average public spends at least 14 minutes a day on the use of mobile phones. With the general public's tendency to hold mobile phones, technicians in the technical field have proposed various solutions, hoping to verify the user's information. The combination of the mobile phone and the mobile phone is used for verification, so that the user can directly perform small consumption or various operations after the verification is passed.
然而，使用行動電話來進行驗證，使用者仍然需要執行額外的步驟，或是操作額外的裝置，例如需要輸入密碼、地址或身份ID等，或是需要***或感應卡片。再者，即使是通過行動電話來進行生物特徵辨識，但使用者仍然需要注視相機鏡頭以擷取虹膜資訊，或是按壓行動電話上的特殊部位來擷取指紋或量測心電圖訊號等，實為不便。 However, using a mobile phone for authentication, the user still needs to perform additional steps or operate additional devices, such as a password, address or identity ID, or need to insert or sense a card. Moreover, even if the biometric identification is performed by mobile phone, the user still needs to look at the camera lens to capture the iris information, or press a special part on the mobile phone to capture the fingerprint or measure the electrocardiogram signal, etc. inconvenient.
以上述的生物特徵辨識為例，使用者要令行動電話取得生物特徵，皆需要花費額外的時間，並且執行額外的動作，實不方便，並且也不符合使用者一般使用行動電話時的習慣。換句話說，現有的驗證方式無法有效運 用使用者操作行動電話時的空餘時間(air time)，同時進行量測、判讀與認證，也無法在使用者正常使用行動電話(例如講電話)時，自動完成上述生物特徵的量測，並且直接完成辨識動作。 Taking the above biometric identification as an example, it takes an extra time for the user to obtain the biometric feature of the mobile phone, and it is inconvenient to perform additional actions, and does not conform to the habit of the user generally using the mobile phone. In other words, the existing verification method cannot be effectively transported. When the user operates the mobile phone with the air time, simultaneous measurement, interpretation and authentication, and the user can automatically complete the measurement of the biometrics when the user normally uses the mobile phone (for example, talking on the phone), and Complete the identification action directly.
再者，現今生物特徵辨識的正確率尚有不足。舉例來說，現有技術已可實現以使用者的心電圖(electrocardiogram,ECG)來進行辨識的技術方案。然而，傳統第一導層(Lead-I)的心電圖(即，量測使用者的左手到右手的迴路所得之心電圖)，依現有的分析方式僅能取出為數不多的特徵，正確率始終無法繼續提升。因此，目前所採用的心電圖辨識，僅能進行較低正確率的驗證，也因此無法被運用在需要高安全性的保全領域中。 Moreover, the correct rate of biometric identification is still insufficient. For example, the prior art has realized a technical solution for identifying by a user's electrocardiogram (ECG). However, the traditional first lead layer (Lead-I) electrocardiogram (ie, the ECG obtained by measuring the user's left-to-right hand loop) can only extract a few features according to the existing analysis method, and the correct rate is always impossible. Continue to improve. Therefore, the currently used ECG identification can only be verified with a lower accuracy rate, and therefore cannot be used in the field of security where high security is required.
本發明之主要目的，在於提供一種心電圖量測裝置及其量測方法，係可將傳統第一導層(Lead-I)的心電圖以生理身體自然結構一分為多，藉此增加心電圖上可供辨識的特徵數，進而提昇辨識的正確率，同時，此一生理現象係依不同人體的特徵性而有所不同，並且無法以肉眼直接觀察得知，故甚為安全。 The main object of the present invention is to provide an electrocardiogram measuring device and a measuring method thereof, which can divide the electrocardiogram of the traditional first guiding layer (Lead-I) into a plurality of physiological body natural structures, thereby increasing the electrocardiogram. The number of features to be identified, thereby improving the accuracy of identification, at the same time, this physiological phenomenon is different according to the characteristics of different human bodies, and can not be directly observed by the naked eye, so it is very safe.
本發明之另一主要目的，在於提供一種心電圖量測裝置及其量測方法，係可通過量測裝置在本體上所設置的電極片，令使用者在正常使用量測裝置的情況下同時進行心電圖的量測，藉此令使用者不必再執行額外的量測行為。 Another main object of the present invention is to provide an electrocardiogram measuring device and a measuring method thereof, which are provided by the measuring device on the main body, so that the user can simultaneously perform the normal use of the measuring device. The measurement of the electrocardiogram allows the user to eliminate the need for additional measurement behavior.
為達上述目的，本發明的量測裝置在本體上設置有至少二電極片，當使用者正常使用量測裝置時，二電極片恰好觸及使用者的手部及面部。量測方法係通過二電極片分別量測使用者的左手至左邊面部的第一心電圖訊號，以及右手至右邊面部的第二心電圖訊號。進一步，分別由第一心電圖訊號及第二心電圖訊號與其交互運算之結果(如加減法與相關係數)來擷取出複數心電圖特徵，並且藉由上述綜合特徵來進行心電圖生物特徵辨識。 In order to achieve the above object, the measuring device of the present invention is provided with at least two electrode sheets on the body, and when the user normally uses the measuring device, the two electrode sheets just touch the user's hand and face. The measuring method measures the first electrocardiogram signal of the left hand to the left side of the user and the second electrocardiogram signal of the right hand to the right side by the two electrode sheets. Further, the plurality of electrocardiogram features are extracted by the first electrocardiogram signal and the second electrocardiogram signal and the result of the interleaving operation (such as addition and subtraction and correlation coefficient), and the electrocardiogram biometric identification is performed by the integrated feature.
本發明對照現有技術所能達成之功效在於，可將行動裝置，例如行動電話本身當作量測裝置，並且在量測裝置的本體，例如殼體的正面、背面、側面或是顯示螢幕上分別設置電極片。藉此，可以在使用者正常使用行動裝置(例如接聽電話)時，同時為使用者量測辨識所需之心電圖。藉此，使用 者要進行心電圖生物特徵辨識時，不需要再執行額外的量測動作，因而可以省去使用者的麻煩。 The effect of the present invention over the prior art is that a mobile device, such as a mobile phone itself, can be used as a measuring device, and on the body of the measuring device, such as the front, back, side or display screen of the housing, respectively. Set the electrode pads. Thereby, when the user normally uses the mobile device (for example, answering the telephone), the user can measure the desired electrocardiogram at the same time. Use this When performing ECG biometric identification, it is not necessary to perform additional measurement actions, thereby eliminating the trouble of the user.
再者，本發明將傳統第一導層的心電圖，即，量測使用者的左手至右手的心電圖，依據人體的特徵性區分為量測使用者的左手至左邊臉部的心電圖，以及右手至右邊臉部的心電圖，並可將上述二心電圖相互運算，進而得到更多訊息。如此一來，可以用來進行辨識的心電圖特徵數將會增加一倍以上，辨識的正確率也可增加一倍以上。 Furthermore, the present invention divides the electrocardiogram of the conventional first guiding layer, that is, the left-to-right hand electrocardiogram of the user, according to the characteristics of the human body, to measure the electrocardiogram of the left hand to the left side of the user, and the right hand to The electrocardiogram of the right side of the face, and the two ECGs can be inter-calculated to get more information. As a result, the number of ECG features that can be used for identification will more than double, and the accuracy of recognition can be more than doubled.
另一方面，本發明的量測裝置還可為一用以包覆使用者的行動裝置的防護殼，該防護殼在對應位置上設置有上述量測用的電極片。藉此，可通過防護殼來令即有的行動裝置擴充使用心電圖的量測功能，藉此降低使用者的添購成本。 On the other hand, the measuring device of the present invention may also be a protective casing for covering the user's mobile device, and the protective casing is provided with the above-mentioned electrode sheets for measurement at corresponding positions. Thereby, the protective device can be used to expand the measurement function of the electrocardiogram by using the mobile device, thereby reducing the user's purchase cost.

首請參閱第一圖、第二圖、第三圖及第四圖，第一圖本創作的第一具體實施例的量測裝置正視圖，第二圖為本創作的第二具體實施例的量測裝置後視圖，第三圖為本創作的第一具體實施例的第一心電圖量測示意圖，第四圖為本創作的第一具體實施例的第二心電圖量測示意圖。本創作主要揭露了一種心電圖(Electrocardiogram,ECG)的量測方法，以及用以實現該量測方法的一心電圖量測裝置(下述簡稱為該量測裝置1)。本實施例中，該量測裝置1可為一行動裝置，例如一智慧型行動電話，但不加以限定。 Referring to the first, second, third and fourth figures, the first figure is a front view of the measuring device of the first specific embodiment of the present invention, and the second figure is the second embodiment of the present invention. The rear view of the measuring device, the third figure is a first electrocardiogram measurement diagram of the first embodiment of the creation, and the fourth figure is a second electrocardiogram measurement diagram of the first embodiment of the creation. The present invention mainly discloses an electrocardiogram (ECG) measurement method, and an electrocardiogram measurement device (hereinafter referred to as the measurement device 1) for implementing the measurement method. In this embodiment, the measuring device 1 can be a mobile device, such as a smart mobile phone, but is not limited.
該量測裝置1主要係於本體上設置有複數的電極片，例如，該量測裝置1可於其殼體10的側面或背面上設置有一第一電極片11，並於該殼體10的正面上設置有一第二電極片12。再例如，若該電極片11、12為石墨烯所製成，則因石墨烯幾近透明之特性，該電極片11或12還可直接設置在該量測裝置1的一顯示螢幕14上。藉此，可在不影響到該顯示螢幕14的正常使用的前提下，將該電極片11、12與該顯示螢幕14設置在一起。為便於說明，下面將於說明書中以將該二電極片11、12設置在該殼體10上的方式來舉例說明，但不加以限定。 The measuring device 1 is mainly provided with a plurality of electrode sheets on the body. For example, the measuring device 1 can be provided with a first electrode sheet 11 on the side or the back surface of the housing 10, and the housing 10 is A second electrode sheet 12 is disposed on the front surface. For example, if the electrode sheets 11 and 12 are made of graphene, the electrode sheets 11 or 12 may be directly disposed on a display screen 14 of the measuring device 1 due to the nearly transparent nature of the graphene. Thereby, the electrode sheets 11, 12 and the display screen 14 can be disposed together without affecting the normal use of the display screen 14. For convenience of explanation, the two electrode sheets 11, 12 are exemplified in the description below, but are not limited thereto.
本創作主要是通過該量測裝置1上的該二電極片11、12，於一使用者2正常使用該量測裝置1(例如接聽電話)的狀態下觸及該使用者2的手部21及面部22，藉此為該使用者2進行心電圖訊號的量測。通過本創作，該使用者2不需要執行額外的量測動作，該量測裝置1就可以在空餘時間(air time)來為該使用者2進行量測。 The present invention mainly uses the two electrode sheets 11 and 12 on the measuring device 1 to touch the hand 21 of the user 2 in a state in which the user 2 normally uses the measuring device 1 (for example, answering a telephone). The face 22 is used to measure the electrocardiogram signal for the user 2. By this creation, the user 2 does not need to perform an additional measurement action, and the measurement device 1 can measure the user 2 at the air time.
該量測裝置1主要是在該使用者2接聽電話的狀態下，通過該第一電極片11觸及該使用者2的手部21，並且通過該第二電極片12觸及該使用者2的面部。只要能有效與該使用者2接觸，該些電極片11的設置位置可以適度調整，並非以圖中所示者為限。 The measuring device 1 mainly touches the hand 21 of the user 2 through the first electrode sheet 11 and touches the face of the user 2 through the second electrode sheet 12 in a state where the user 2 answers the call. . The position of the electrode sheets 11 can be appropriately adjusted as long as it can effectively contact the user 2, and is not limited to those shown in the drawings.
第一圖中該第一電極片11係以設置於該殼體10的側面為例，以觸及該 使用者2的手指，第二圖中該第一電極片11係以設置於該殼體10的背面為例，以觸及該使用者2的手掌。再者，該第二電極片12較佳係設置於該殼體10的正面頂部，以觸及該使用者2的耳朵，但並不以此為限。例如前文所述，該二電極片11、12亦可為石墨烯製成，並且直接設置於該顯示螢幕14上。並且，該些電極片11、12係需與該使用者2直接接觸，因此需裸露於該殼體10或該顯示螢幕14之外。或者，該殼體10或該顯示螢幕14的部分區域可以導電材質製成，藉此該些電極片11、12可設置於該殼體10或該顯示螢幕14的內部，並且通過該些導電區域來與該使用者2接觸。 In the first figure, the first electrode sheet 11 is exemplified on a side surface of the housing 10 to touch the first electrode sheet 11 . The finger of the user 2, in the second figure, the first electrode sheet 11 is exemplified on the back surface of the casing 10 to touch the palm of the user 2. Furthermore, the second electrode sheet 12 is preferably disposed on the front surface of the housing 10 to touch the ear of the user 2, but is not limited thereto. For example, as described above, the two electrode sheets 11, 12 may also be made of graphene and directly disposed on the display screen 14. Moreover, the electrode sheets 11, 12 need to be in direct contact with the user 2, and therefore need to be exposed outside the housing 10 or the display screen 14. Alternatively, the housing 10 or a portion of the display screen 14 may be made of a conductive material, whereby the electrode sheets 11, 12 may be disposed inside the housing 10 or the display screen 14 and pass through the conductive regions. Come in contact with the user 2.
傳統第一導層(Lead-I)的心電圖，主要是量測使用者的左手到右手之迴路所得的心電圖。本創作的主要技術手段在於，將左手到右手的迴路從身體中間切開，藉以將傳統第一導層的心電圖一分為二，區分為量測使用者的左手到左邊面部的心電圖，以及右手到右邊面部的心電圖等兩部分。值得一提的是，本創作是依據人體的自然結構，將傳統第一導層的心電圖一分為二，藉此增加可供辨識的特徵的數量，進而提昇辨識的正確率。並且，二心電圖的內容會因不同人體的特徵性而有所不同，並且無法以肉眼直接觀察得知，故還可進一步提高辨識的安全性。 The ECG of the traditional first guide layer (Lead-I) is mainly an electrocardiogram obtained by measuring the loop of the user's left hand to the right hand. The main technical means of this creation is to cut the loop of the left hand to the right hand from the middle of the body, thereby dividing the electrocardiogram of the traditional first guide layer into two, and distinguishing the electrocardiogram of the left hand to the left face of the user, and the right hand to The electrocardiogram of the right side of the face and other two parts. It is worth mentioning that this creation is based on the natural structure of the human body, dividing the electrocardiogram of the traditional first guiding layer into two, thereby increasing the number of features that can be identified, thereby improving the correct rate of identification. Moreover, the content of the two electrocardiograms may vary according to the characteristics of different human bodies, and cannot be directly observed by the naked eye, so the safety of identification can be further improved.
並且，本案是將傳統第一導層的心電圖一分為二，以得到左邊的心電圖及右邊的心電圖，因此可以得到更多的訊息。並且，這樣的心電圖還可以當作呼吸偵測，以及心臟偏右處的特殊疾病之量測，藉以做為未來醫療診斷之用。 Moreover, in this case, the electrocardiogram of the traditional first guiding layer is divided into two to obtain the left electrocardiogram and the right electrocardiogram, so that more information can be obtained. Moreover, such an electrocardiogram can also be used as a measure of respiration and a measure of a particular disease at the right side of the heart for future medical diagnosis.
再者，依據人體的特性，雖將原本量測使用者的左手到右手之迴路所得的心電圖，區分為量測左手到左邊面部的心電圖A，與量測右手到右邊面部的心電圖B，然而，上述的心電圖A與心電圖B相加，並不會等於量測使用者的左手到右手之迴路所得的心電圖。為更明確說明，遂列出其計算公式如下：Lead I ECG(traditional)=Lead I ECG(right side)+Lead I ECG(left side)+Remain components。 Furthermore, according to the characteristics of the human body, the electrocardiogram obtained by measuring the left-handed to right-handed loop of the user is divided into an electrocardiogram A measuring the left hand to the left side, and an electrocardiogram B measuring the right hand to the right side, however, The above-mentioned electrocardiogram A is added to the electrocardiogram B, and is not equal to the electrocardiogram obtained by measuring the left-hand to right-hand loop of the user. For a more specific explanation, 计算 list its calculation formula as follows: Lead I ECG (traditional) = Lead I ECG (right side) + Lead I ECG (left side) + Remain components.
由上述公式可看出，傳統第一導層的心電圖，實等於量測左手到左邊面部的心電圖，加上量測右手到右邊面部的心電圖，再加上因人體特性而無法由本創作的方式直接量測得出的心電圖部分。換句話說，通過本創作 的方式進行量測，除了可將傳統第一導層的心電圖一分為二之外，經由上述心電圖的交互運算，實可得到三張不同之心電圖。也就是說，於較佳的情況下，可用以辨識的特徵數，以及辨識的正確率皆可提昇三倍。下面敘述中，係先以將傳統第一導層的心電圖一分為二之實例來舉例說明。 It can be seen from the above formula that the electrocardiogram of the traditional first guiding layer is equivalent to measuring the electrocardiogram of the left hand to the left side face, plus the electrocardiogram measuring the right hand to the right side face, and the direct inability to be directly created by the present method due to the characteristics of the human body. The measured ECG portion. In other words, through this creation In the way of measuring, in addition to dividing the electrocardiogram of the traditional first guiding layer into two, through the above-mentioned interaction calculation of the electrocardiogram, three different electrocardiograms can be obtained. That is to say, in the preferred case, the number of features that can be used for identification, and the correct rate of recognition can be increased by three times. In the following description, an example in which the electrocardiogram of the conventional first conductive layer is divided into two is exemplified.
如第三圖及第四圖所示，該量測裝置1係讓該二電極片11、12貼覆於該使用者2的左手與左邊臉部(較佳為左耳)，藉以從左手到左邊臉部的迴路來量測得出一第一心電圖訊號(如第七圖B所示的第一心電圖訊號31)。並且，該量測裝置1還讓該二電極片11、12貼覆於該使用者2的右手與右邊臉部(較佳為右耳)，藉以從右手到右邊臉部的迴路來量測得出一第二心電圖訊號(如第七圖C所示的第二心電圖訊號32)。 As shown in the third and fourth figures, the measuring device 1 is configured such that the two electrode sheets 11 and 12 are attached to the left and left faces of the user 2 (preferably the left ear), thereby The loop of the left face measures a first electrocardiogram signal (such as the first electrocardiogram signal 31 shown in Figure 7B). Moreover, the measuring device 1 also allows the two electrode sheets 11, 12 to be attached to the right hand and the right side of the user 2 (preferably the right ear), thereby measuring the loop from the right hand to the right side. A second electrocardiogram signal is generated (such as the second electrocardiogram signal 32 shown in FIG. C).
本創作的主要技術功效在於，若通過一般的特徵擷點法可由一心電圖訊號中擷取出n個心電圖特徵，則本創作將傳統的心電圖一分為二，故共可於該二心電圖訊號31、32中擷取出2n個心電圖特徵。換句話說，在進行心電圖生物特徵辨識時，將會有至少2n個心電圖特徵可供辨識使用，因此可以有效地提昇辨識的正確率。 The main technical effect of this creation is that if the n-cardiogram features are extracted from an ECG signal by the general feature point method, the original ECG is divided into two, so that the two ECG signals 31 can be shared. 32 撷 extracted 2n ECG features. In other words, when ECG biometrics are performed, at least 2n ECG features will be available for identification, so that the correct rate of recognition can be effectively improved.
參閱第五圖，為本創作的第一具體實施例的量測裝置方塊圖。該量測裝置1包括該第一電極片11、該第二電極片12、一微處理器13及一顯示螢幕14，該微處理器13電性連接該第一電極片11、該第二電極片12及該顯示螢幕14。其中，該第一電極片11、該第二電極片12與該顯示螢幕裸露於該殼體10上，而該微處理器13則設置於該殼體10內部。更甚者，該二電極片11、12還可直接設置在該顯示螢幕14上，但不加以限定。 Referring to the fifth figure, a block diagram of the measuring device of the first embodiment of the present invention is shown. The measuring device 1 includes the first electrode sheet 11, the second electrode sheet 12, a microprocessor 13 and a display screen 14. The microprocessor 13 is electrically connected to the first electrode sheet 11 and the second electrode. The sheet 12 and the display screen 14. The first electrode sheet 11 , the second electrode sheet 12 and the display screen are exposed on the casing 10 , and the microprocessor 13 is disposed inside the casing 10 . Moreover, the two electrode sheets 11, 12 can also be directly disposed on the display screen 14, but are not limited.

When the two electrode sheets 11 and 12 respectively touch the left and left sides of the user 2, the microprocessor 13 can control the measurement to obtain the first An ECG signal 31. When the two electrode sheets 11 and 12 respectively touch the right hand and the right side surface of the user 2, the microprocessor 13 can control the measurement to obtain the second electrocardiogram signal 32. At the same time, the microprocessor 13 can perform basic processing on the obtained first electrocardiogram signal 31 and the second electrocardiogram signal 32, for example, performing signal amplification, analog/digital conversion, etc., which is a technical field.

Therefore, when the user holds the measuring device 1 with the left hand, the light of the detecting unit 19 on the right side of the casing 10 is blocked by the thumb of the left hand, so the measuring device 1 can judge the current measurement. The first electrocardiogram signal 31 of the user's left hand to the left side; conversely, when the user holds the measuring device 1 with the right hand, the light of the detecting unit 19 on the left side of the housing 10 is the right thumb Therefore, the measuring device 1 can determine that the second electrocardiogram signal 32 of the right hand to the right side of the user is now measured.
該量測裝置1還可包含一儲存單元15，該儲存單元15設置於該殼體10內部，並且電性連接該微處理器13，該儲存單元15中儲存有至少一心電圖模板151。更具體而言，若要進行辨識，則該使用者2需預先量測該第一心電圖訊號31及該第二心電圖訊號32，並儲存於該儲存單元15中，以做為該至少一心電圖模板151。在進行生物特徵辨識時，該微處理器13主要是在量測取得該第二心電圖訊號31、32，並且擷取出該些心電圖特徵後，再將該些心電圖特徵與該至少一心電圖模板151中的心電圖特徵進行比對，藉以判斷該使用者2是否可通過生物特徵辨識。舉例來說，該微處理器13可被預先寫入相關程式，並以時域軸分析、頻譜分析、及亂度分析等方式來進行比對，以為該使用者2進行生物特徵辨識，但不加以限定。 The measuring device 1 can also include a storage unit 15 disposed inside the housing 10 and electrically connected to the microprocessor 13 . The storage unit 15 stores at least one electrocardiogram template 151 . More specifically, if the identification is to be performed, the user 2 needs to measure the first electrocardiogram signal 31 and the second electrocardiogram signal 32 in advance, and store the same in the storage unit 15 as the at least one electrocardiogram template. 151. When performing the biometric identification, the microprocessor 13 mainly obtains the second electrocardiogram signals 31 and 32, and extracts the electrocardiogram features and the at least one electrocardiogram template 151. The ECG features are compared to determine whether the user 2 can pass biometric identification. For example, the microprocessor 13 can be pre-written into the relevant program and compared by time domain axis analysis, spectrum analysis, and ambiguity analysis to perform biometric identification for the user 2, but not Limited.
具體來說，該微處理器13是先由該二心電圖訊號31、32中取出預定數量的心電圖特徵，並且再通過相同的方式，由該至少一心電圖模板151中取出對應數量的心電圖特徵，最後再比對該些心電圖特徵是否符合，進而判斷該使用者2是否可通過生物特徵辨識。值得一提的是，該至少一心電圖模板151可由該量測裝置1來量測並儲存，也可以由其他設備來對該使用者2進行量測(例如於醫院中進行量測)後，再傳送到該量測裝置1中儲存， 不加以限定。 Specifically, the microprocessor 13 first extracts a predetermined number of electrocardiogram features from the two electrocardiogram signals 31, 32, and in the same manner, extracts a corresponding number of electrocardiogram features from the at least one electrocardiogram template 151, and finally Then, whether the ECG features are consistent or not, and whether the user 2 can pass the biometric identification. It is worth mentioning that the at least one electrocardiogram template 151 can be measured and stored by the measuring device 1 or can be measured by other devices (for example, in a hospital), and then Transferred to the measuring device 1 for storage, Not limited.
該量測裝置1還包括有一傳輸單元16，該傳輸單元16設置於該殼體10內部，並且電性連接該微處理器13。如前所述，該量測裝置1可通過該微處理器13來取出該些心電圖特徵，並且將該些心電圖特徵與該至少一心電圖模板151進行比對。於另一實施例中，該量測裝置1係僅通過該二電極片11、12來取出該些心電圖特徵，並且經過該微處理器13的訊號放大、類比/數位轉換等處理後，再通過該傳輸單元16傳送至外部的一伺服器(如第八圖中所示的伺服器42)。該伺服器42中儲存有該使用者2預先量測的至少一心電圖模板421，藉此該伺服器可為該使用者2進行生物特徵辨識。 The measuring device 1 further includes a transmission unit 16 disposed inside the housing 10 and electrically connected to the microprocessor 13. As described above, the measuring device 1 can take out the electrocardiographic features through the microprocessor 13 and compare the electrocardiographic features with the at least one electrocardiogram template 151. In another embodiment, the measuring device 1 takes out the electrocardiographic features only through the two electrode sheets 11, 12, and passes through the signal amplification, analog/digital conversion, etc. of the microprocessor 13, and then passes. The transmission unit 16 transmits to an external server (such as the server 42 shown in the eighth figure). The server 42 stores at least one electrocardiogram template 421 pre-measured by the user 2, whereby the server can perform biometric identification for the user 2.
然而，要由該量測裝置1或該伺服器42來為該使用者2進行辨識，應視實際所需而定，不加以限定。若由該量測裝置1來進行，則該微處理器13需具備有於該二心電圖訊號31、32中取出心電圖特徵的功能，並且該使用者2需預先量測該至少一心電圖模板151並儲存於該量測裝置1中。反之若由該伺服器42來進行，則該伺服器42需具備有接收該二心電圖訊號31、32，以及從該二心電圖訊號31、32中取出心電圖特徵的功能，並且，使用者2還需預先量測該至少一心電圖模板421並儲存於該伺服器42中。本實施例中，該至少一心電圖模板151與該至少一心電圖模板421係為相同，並且皆對應至該二心電圖訊號31、32。 However, the identification of the user 2 by the measuring device 1 or the server 42 should be determined according to actual needs and is not limited. If the measurement device 1 is used, the microprocessor 13 needs to have the function of taking out the ECG features in the two electrocardiogram signals 31, 32, and the user 2 needs to measure the at least one electrocardiogram template 151 in advance. It is stored in the measuring device 1. On the contrary, if the server 42 is used, the server 42 needs to have the function of receiving the two electrocardiogram signals 31, 32 and extracting the electrocardiogram features from the two electrocardiogram signals 31, 32, and the user 2 needs to The at least one electrocardiogram template 421 is pre-measured and stored in the server 42. In this embodiment, the at least one electrocardiogram template 151 is identical to the at least one electrocardiogram template 421 and corresponds to the two electrocardiogram signals 31, 32.
該量測裝置1還可包括一揚聲單元17及一麥克風18，分別設置於該殼體10內，並且分別電性連接該微處理器13。本實施例中，該量測裝置1係由該使用者2的左手至左邊面部的迴路來量測該第一心電圖訊號31，並且再由該使用者2的右手至右邊面部的迴路來量測該第二心電圖訊號32。為通知該使用者2是否量測完畢，以及是否要換邊進行量測，以利量測動作的進行，故在該第一心電圖訊號31與該第二心電圖訊號32量測完成後，該微處理器13可以控制該揚聲單元17發出提示聲響，以提醒該使用者2換邊量測。 The measuring device 1 can further include a speaker unit 17 and a microphone 18 respectively disposed in the housing 10 and electrically connected to the microprocessor 13 respectively. In the embodiment, the measuring device 1 measures the first electrocardiogram signal 31 from the loop of the left hand to the left side of the user 2, and is measured by the loop of the right hand to the right side of the user 2 The second electrocardiogram signal 32. In order to inform the user 2 whether the measurement is completed, and whether the measurement is to be changed, in order to facilitate the measurement operation, after the first electrocardiogram signal 31 and the second electrocardiogram signal 32 are measured, the micro The processor 13 can control the speaker unit 17 to emit a prompt sound to remind the user 2 to change the edge measurement.
本實施例中，為了有效提昇安全性，除了該第一心電圖訊號31及該第二心電圖訊號32之外，該量測裝置1更可加入該使用者2的聲音，做為生物特徵辨識的另一參數。如第五圖中所示，該儲存單元15中儲存有該使用者2預先輸入的一語音資訊152，當該量測裝置1要為該使用者2進行辨識 時，除了將該些心電圖特徵與該至少一心電圖模板151進行比對外，還通過該麥克風18接收該使用者2輸入的一語音訊號，並且將該語音訊號與該語音資訊152進行比對。藉此，同時由該些心電圖特徵與該至少一心電圖模板151的比對結果，以及該語音訊號與該語音資訊152的比對結果，判斷該使用者2是否可通過辨識。 In this embodiment, in order to effectively improve the security, in addition to the first electrocardiogram signal 31 and the second electrocardiogram signal 32, the measuring device 1 can further add the sound of the user 2 as another biometric identification. One parameter. As shown in the fifth figure, the storage unit 15 stores a voice information 152 input by the user 2 in advance, and the measuring device 1 is to identify the user 2 The voice signal input by the user 2 is received by the microphone 18 and compared with the voice information 152. Thereby, the comparison result of the electrocardiogram features and the at least one electrocardiogram template 151 and the comparison result of the voice signal and the voice information 152 are used to determine whether the user 2 can pass the identification.
參閱第六圖，為本創作的第一具體實施例的量測流程圖。首先，該量測裝置1量測取得該使用者2的左手至左邊面部的該第一心電圖訊號31(步驟S10)，接著，量測取得該使用者2的右手至右邊面部的該第二心電圖訊號32(步驟S12)。具體而言，步驟S10中，該使用者2係將該第一電極片11貼覆在左手，並將該第二電片11貼覆在左邊面部，以令該量測裝置1量測該第一心電圖訊號31。而步驟S12中，該使用者2則將該第一電極片11貼覆在右手，並將該第二電片11貼覆在右邊面部，以令該量測裝置1量測該第二心電圖訊號32。本實施例中，該量測裝置1可預設必須先量測該第一心電圖訊號31，或是預設必須先量測該第二心電圖訊號32，不應加以限定。而於另一實施例中，該量測裝置1亦可讓該使用者2依照自訂的順序進行量測，並且通過該至少一偵測單元19判斷目前量測的是該第一心電圖訊號31或該第二心電圖訊號32。 Referring to the sixth figure, a measurement flow chart of the first embodiment of the present invention is shown. First, the measuring device 1 measures the first electrocardiogram signal 31 of the left hand to the left side of the user 2 (step S10), and then measures the second electrocardiogram of the right hand to the right side of the user 2 Signal 32 (step S12). Specifically, in step S10, the user 2 attaches the first electrode sheet 11 to the left hand, and attaches the second power sheet 11 to the left side surface, so that the measuring device 1 measures the first An ECG signal 31. In step S12, the user 2 attaches the first electrode sheet 11 to the right hand, and the second electric film 11 is attached to the right side surface, so that the measuring device 1 measures the second electrocardiogram signal. 32. In this embodiment, the measuring device 1 can preset the first electrocardiogram signal 31, or must first measure the second electrocardiogram signal 32, and should not be limited. In another embodiment, the measuring device 1 can also allow the user 2 to perform measurement according to a customized order, and determine, by the at least one detecting unit 19, that the first electrocardiogram signal 31 is currently measured. Or the second electrocardiogram signal 32.
接著，該量測裝置1可選擇性地對該二心電圖訊號31、32進行雜訊濾波處理(步驟S14)，以濾除掉辨識過程不需要之訊號。同時，該量測裝置1還可選擇性地對該二心電圖訊號31、32進行訊號放大、類比/數位轉換等處理。該量測裝置1還可選擇性地判斷該二心電圖訊號31、32是否可通過一前置淘汰(prescreen)處理(步驟S16)。若該二心電圖訊號31、32無法通過該前置淘汰處理，則該量測裝置1直接判斷辨識失敗(步驟S18)，並可將對外發出一失敗訊息，或是顯示在該顯示螢幕14上。 Then, the measuring device 1 can selectively perform noise filtering processing on the two electrocardiogram signals 31 and 32 (step S14) to filter out signals not required by the identification process. At the same time, the measuring device 1 can also selectively perform signal amplification, analog/digital conversion and the like on the two electrocardiogram signals 31 and 32. The measuring device 1 can also selectively determine whether the two electrocardiogram signals 31, 32 can pass a prescreen processing (step S16). If the two ECG signals 31, 32 cannot pass the pre-emption processing, the measuring device 1 directly determines that the identification has failed (step S18), and may send a failure message to the outside or display on the display screen 14.
上述的該前置淘汰處理，係直接將該二心電圖訊號31、32的圖像與該至少一心電圖模板151的圖像進行比對，若該二心電圖訊號31、32與該至少一心電圖模板151具有很大的差異，則該量測裝置1不再進行該些心電圖特徵的比對，而是直接認定辨識失敗。值得一提的是，該步驟S14及S16係為選擇性步驟，不必然執行，並且也沒有執行上的順序關係。 The pre-emption processing described above directly compares the image of the two electrocardiogram signals 31 and 32 with the image of the at least one electrocardiogram template 151, if the two electrocardiogram signals 31, 32 and the at least one electrocardiogram template 151 If there is a big difference, the measuring device 1 no longer performs the comparison of the electrocardiographic features, but directly determines that the identification fails. It is worth mentioning that the steps S14 and S16 are optional steps, which are not necessarily performed, and there is no order relationship in execution.
該步驟S12、S14或S16後，該量測裝置1接著由該第一心電圖訊號31 及該第二心電圖訊號32中，分別擷取出預定數量的心電圖特徵(步驟S20)，並且將該些心電圖特徵與該至少一心電圖模板151進行比對(步驟S22)。本實施例中，該量測裝置1主要是採用一心電圖特徵擷點法，由該第一心電圖訊號31中取出n個心電圖特徵，並由該第二心電圖訊號32中取出n個心電圖特徵，藉以與該至少一心電圖模板151中取出的心電圖特徵進行比對(容下述詳)。其中，n的數量取決於所設定的精準度，可能為10~25個，但不加以限定。 After the step S12, S14 or S16, the measuring device 1 is followed by the first electrocardiogram signal 31. And the second electrocardiogram signal 32, respectively extracting a predetermined number of electrocardiogram features (step S20), and comparing the electrocardiogram features with the at least one electrocardiogram template 151 (step S22). In the embodiment, the measuring device 1 mainly adopts an electrocardiographic feature point method, and extracts n electrocardiogram features from the first electrocardiogram signal 31, and extracts n electrocardiogram features from the second electrocardiogram signal 32, thereby The ECG features taken out from the at least one electrocardiogram template 151 are compared (described below). The number of n depends on the accuracy set, and may be 10~25, but it is not limited.
最後，該量測裝置1依據比對結果，判斷該使用者2是否可通過生物特徵辨識(步驟S24)，若無法通過辨識，則該量測裝置1發出該失敗訊息；反之，若通過辨識，則該量測裝置1令該使用者2進行後續作動(步驟S26)。例如若該量測裝置1為行動電話，則可在該使用者2辨識通過後，執行畫面解鎖、撥話、電話銀行(tel-bank)的授權，或是控制與該量測裝置1連接的其他裝置等等，不加以限定。 Finally, the measuring device 1 determines whether the user 2 can pass the biometric identification according to the comparison result (step S24). If the identification is not possible, the measuring device 1 issues the failure message; Then, the measuring device 1 causes the user 2 to perform subsequent operations (step S26). For example, if the measuring device 1 is a mobile phone, after the user 2 recognizes the pass, the screen unlocking, dialing, tel-bank authorization, or controlling the connection with the measuring device 1 can be performed. Other devices and the like are not limited.
請參閱第七圖A至第七圖D，第七圖A為本創作的第一具體實施例的完整心電圖示意圖，第七圖B為本創作的第一具體實施例的第一心電圖示意圖，第七圖C為本創作的第一具體實施例的第二心電圖示意圖，第七圖D為本創作的第一具體實施例的特徵點示意圖。第七圖A中所示者，為正常通過使用者的左手至右手的迴路來量測所得的心電圖訊號，即，傳統第一導層的心電圖訊號，本實施例中稱為一完整心電圖訊號3。 Referring to FIG. 7A to FIG. 7D, FIG. 7A is a schematic diagram of a complete electrocardiogram of the first embodiment of the present invention, and FIG. 7B is a schematic diagram of a first electrocardiogram of the first embodiment of the present invention. 7 is a schematic diagram of a second electrocardiogram of the first embodiment of the creation, and FIG. 7D is a schematic diagram of a feature point of the first embodiment of the creation. The figure shown in the seventh figure A is used to measure the obtained electrocardiogram signal through the left-to-right hand loop of the user, that is, the electrocardiogram signal of the conventional first guiding layer, which is referred to as a complete electrocardiogram signal 3 in this embodiment. .
第七圖B中所示者為上述的該第一心電圖訊號31，而第七圖C中所示者為上述的該第二心電圖訊號32。本創作係以使用者的面部為中心，將左手至右手的迴路切割為左手至左邊面部的迴路+右手至右邊面部的迴路。然而如上所述，本創作通過特殊的量測方法將該完整第一心電圖訊號3切割為該第一心電圖訊號31與該第二心電圖訊號32，但該第一心電圖訊號31與該第二心電圖訊號32相加後，並不會等於該完整心電圖訊號3，而會因為人體特性而具有差異(即，前述公式中的Remain components)，本創作中將該差異視為一第三心電圖訊號(如第十四圖所示的第三心電圖訊號33)。並且，該第三心電圖訊號33也可做為生物特徵辨識的一個參數(容後詳述)。 The first electrocardiogram signal 31 is shown in the seventh figure B, and the second electrocardiogram signal 32 is shown in the seventh figure C. This creation is based on the user's face, cutting the loop from left to right hand into the loop from left to left face + loop from right hand to right face. However, as described above, the present invention cuts the complete first electrocardiogram signal 3 into the first electrocardiogram signal 31 and the second electrocardiogram signal 32 by a special measurement method, but the first electrocardiogram signal 31 and the second electrocardiogram signal 32, after adding, does not equal the complete ECG signal 3, but will have differences due to human characteristics (ie, Remain components in the above formula). In the present creation, the difference is regarded as a third electrocardiogram signal (such as The third electrocardiogram signal shown in Figure 14). Moreover, the third electrocardiogram signal 33 can also be used as a parameter of biometric identification (described in detail later).
第七圖D係以該第一心電圖訊號31中的一個完整心跳波型為例，說明心電圖訊號上所具備的心電圖特徵。如圖所示，每一個心跳波型皆具備有
P、Q、R、S、T的特徵點，而其相對位置則因人而易，此為醫學上的通常知識，在此不再贅述。藉由該些特徵點、以及該些特徵點之間的相對關係，即可實現由心電圖訊號來進行生物特徵辨識的目的。本創作中，主要是通過上述的心電圖特徵擷點法，由該些心電圖訊號3、31、32、33中取出如下表所示的各項心電圖特徵，其中該特徵擷點法為本領域的常用手段，於此不再贅述：
採用該心電圖特徵擷點法，一般可從該完整心電圖訊號3中取得上述17個心電圖特徵。其中，“amplitude”指點到點之間的振幅高度；“duration”指點到點之間的時間長度；“slope”為斜率；“angle”指該點的角度。其中，該些心電圖特徵的數量係以所設定的精準度而定，並非以17個為限。 With the ECG feature point method, the above 17 electrocardiogram features can generally be obtained from the complete electrocardiogram signal 3. Where "amplitude" refers to the height of the amplitude between points; "duration" refers to the length of time between points; "slope" is the slope; "angle" refers to the angle of the point. Among them, the number of the electrocardiogram features is determined by the set accuracy, not limited to 17.
本創作將該完整心電圖訊號3切割為該第一心電圖訊號31及該第二心電圖訊號32，更甚者還可計算得出該第三心電圖訊號33。故若採用該心電圖特徵擷點法，則該量測裝置1共可由該三心電圖訊號31、32、33中取出至少17 * 3=51個心電圖特徵，因此可有效提昇辨識的正確率。再者，若採用其他的方法可從該完整心電圖訊號3中取得n個心電圖特徵，則以該方法來分析該三心電圖訊號31、32、33，可取得至少3n個心電圖特徵。 The whole ECG signal 3 is cut into the first electrocardiogram signal 31 and the second electrocardiogram signal 32, and the third electrocardiogram signal 33 can be calculated. Therefore, if the electrocardiographic feature point method is adopted, the measuring device 1 can take out at least 17 * 3 = 51 electrocardiogram features from the three electrocardiogram signals 31, 32, and 33, thereby effectively improving the accuracy of the identification. Furthermore, if n electrocardiographic features can be obtained from the complete electrocardiogram signal 3 by other methods, the three electrocardiogram signals 31, 32, and 33 can be analyzed by the method to obtain at least 3n electrocardiographic features.
值得一提的是，於該三心電圖訊號31、32、33之間，還可以加減法或其他方式進行交互運算，以計算出兩兩之間的相關係數，因此以一個心電圖訊號可以取出17個心電圖特徵為例，則該三心電圖訊號31、32、33將可取出51+3=54個心電圖特徵。然而，以上所述皆僅為本創作的一較佳具體實例，並不以此為限。 It is worth mentioning that between the three ECG signals 31, 32, 33, it is also possible to add and subtract or other methods to calculate the correlation coefficient between the two, so that 17 can be taken out with one ECG signal. Taking the ECG feature as an example, the three electrocardiogram signals 31, 32, 33 will take out 51 + 3 = 54 ECG features. However, the above description is only a preferred embodiment of the present invention, and is not limited thereto.
進一步，通過對該些心電圖訊號3、31、32的分析，還可以分析出該使用者2的肌肉資訊並輸出肌電訊號(electromyography,EMG)，或是分析出該 使用者2的腦波資訊並輸出腦電波(electroencephalogram,EEG)。而若該量測裝置1貼覆的位置靠近該使用者2的眼晴(例如貼覆左耳或右耳)，則還可分析並輸出該使用者2的眨眼訊號(electrooculogram,EOG)。再者，由於量測該使用者2的右手至右邊面部的迴路的該第二心電圖訊號32的起伏較大，故針對該第二心電圖訊號32進行分析，還可以分析得出該使用者2的呼吸次數(respiratory)。藉由上述該些額外的資訊，當該量測裝置1或該伺服器42在進行生物特徵辨識時，還可進一步分析出該使用者2目前的情緒(emotion)，藉此提供額外的服務，或是注意該使用者2的狀況等。值得一提的是，由於該第二心電圖訊號32是以使用者的身體右半部為主要量測對象，故藉由該第二心電圖訊號32，還可供醫療人員分析得出心臟偏右處所患的特殊疾病。 Further, by analyzing the electrocardiogram signals 3, 31, and 32, the muscle information of the user 2 can be analyzed and the electromyography (EMG) can be output, or the User 2's brain wave information and output an electroencephalogram (EEG). If the position of the measuring device 1 is close to the eye of the user 2 (for example, the left ear or the right ear is attached), the user's 2 electrooculogram (EOG) can also be analyzed and output. Furthermore, since the fluctuation of the second electrocardiogram signal 32 of the loop of the right hand to the right side of the user 2 is measured, the second electrocardiogram signal 32 is analyzed, and the user 2 can also be analyzed. The number of breaths (respiratory). With the above additional information, when the measuring device 1 or the server 42 performs biometric identification, the current emotion of the user 2 can be further analyzed, thereby providing additional services. Or pay attention to the condition of the user 2, and the like.

If the signal transmission unit 54 is a wireless transmission unit, the signal transmission unit 54 can be integrated with the amplification processing unit 55, and implemented by an integrated circuit (IC) chip, but is not limited. .
本實施例中，該行動裝置6內部儲存有使用者預先量測的至少一心電圖模板(例如第十二圖中所示的心電圖模板661)，藉此，當該量測裝置5將量測所得的心電圖訊號傳送至該行動裝置6後，該行動裝置6可據以進行比對辨識。 In this embodiment, the mobile device 6 internally stores at least one electrocardiogram template (for example, the electrocardiogram template 661 shown in FIG. 12) measured by the user, whereby the measuring device 5 will measure the measurement. After the ECG signal is transmitted to the mobile device 6, the mobile device 6 can perform the identification.
具體而言，當該第一電極片51及該第二電極片52分別觸及該使用者的左手及左邊面部時，可量測取得該第一心電圖訊號31。而當該第一電極片51及該第二電極片52分別觸及該使用者的右手及右邊面部時，可量測取得該第二心電圖訊號32。接著，該量測裝置5會通過該放大處理單元55對所取得的該第一心電圖訊號31及/或該第二心電圖訊號32進行訊號放大、類比/數位轉換等處理後，再通過該訊號傳輸單元54，將經過處理的該二心電圖訊號31、32傳送至該行動裝置6。該行動裝置可利用該二心電圖訊號31、32來為該使用者進行生物特徵辨識。 Specifically, when the first electrode sheet 51 and the second electrode sheet 52 respectively touch the left and left sides of the user, the first electrocardiogram signal 31 can be measured. When the first electrode sheet 51 and the second electrode sheet 52 respectively touch the right hand and the right side surface of the user, the second electrocardiogram signal 32 can be measured. Then, the measuring device 5 performs signal amplification, analog/digital conversion, and the like on the obtained first electrocardiogram signal 31 and/or the second electrocardiogram signal 32 through the amplification processing unit 55, and then transmits the signal through the signal. The unit 54 transmits the processed two electrocardiogram signals 31, 32 to the mobile device 6. The mobile device can utilize the two electrocardiogram signals 31, 32 to perform biometric identification for the user.
參閱第十二圖，為本創作的第一具體實施例的行動裝置方塊圖。該行動裝置6主要包含有如前述的該量測裝置1中的一微處理器62、一顯示螢幕63、一麥克風64、一揚聲單元65及一儲存單元66等元件。與該量測裝置1的差異在於，該行動裝置6上沒有配置電極片，無法直接為該使用者2進行量測。因此，該行動裝置6需配置有電性連接該微處理器62的一傳輸單元61。該行動裝置6通過該傳輸單元61接收該量測裝置5傳來的該二心電圖訊號31、32，並於該二心電圖訊號31、32中擷取出該些心電圖特徵後，再將該些心電圖特徵與該至少一心電圖模板661進行比對。最後，可依比對結果判斷該使用者2是否可通過辨識。其中，該傳輸單元61的格式需對應至該量測裝置5上的該訊號傳輸單元54的格式。 Referring to Figure 12, a block diagram of a mobile device of a first embodiment of the present invention is shown. The mobile device 6 mainly includes a microprocessor 62, a display screen 63, a microphone 64, a speaker unit 65, and a storage unit 66 in the measuring device 1 as described above. The difference from the measuring device 1 is that the electrode piece is not disposed on the mobile device 6, and the user 2 cannot be directly measured. Therefore, the mobile device 6 needs to be provided with a transmission unit 61 electrically connected to the microprocessor 62. The mobile device 6 receives the two electrocardiogram signals 31 and 32 transmitted by the measuring device 5 through the transmitting unit 61, and extracts the electrocardiogram features from the two electrocardiogram signals 31 and 32, and then performs the electrocardiogram features. The at least one electrocardiogram template 661 is compared. Finally, it can be determined according to the result whether the user 2 can pass the identification. The format of the transmission unit 61 needs to correspond to the format of the signal transmission unit 54 on the measuring device 5.
值得一提的是，該行動裝置6中還可包含至少一偵測單元67，該偵測單元67電性連接該微處理器62。通過該偵測單元67，該微處理器62在接收到該量測裝置5傳來的一心電圖訊號時，可以判斷是量測左手至左邊面部的迴路所得的心電圖訊號、或是量測右手至右邊面部的迴路所得的心電圖訊號。其中，該偵測單元67可例如為一三軸***、一陀螺儀(Gyro)或前文中所述的光線感測器等。 It is worth mentioning that the mobile device 6 can also include at least one detecting unit 67, and the detecting unit 67 is electrically connected to the microprocessor 62. Through the detecting unit 67, when receiving an electrocardiogram signal from the measuring device 5, the microprocessor 62 can determine whether to measure the electrocardiogram signal obtained by the loop from the left hand to the left side, or measure the right hand to The ECG signal from the circuit on the right side of the face. The detecting unit 67 can be, for example, a three-axis positioner, a gyroscope (Gyro) or a light sensor as described in the foregoing.
以三軸***或陀螺儀為例，當該二電極片51、52分別貼覆使用者的左手與左邊面部，或是貼覆使用者的右手與右邊面部時，該行動裝置6會呈現一特殊之傾斜角度(例如第三圖與第四圖所示)，該行動裝置6可通過該偵測單元67來量測該傾斜角度，並且經過計算後，判斷該量測裝置5目前是貼覆在使用者的左手與左邊面部，或是貼覆在使用者的右手與右邊面部。如此一來，就可以判斷出目前正在量測的是該第一心電圖訊號31或是 該第二心電圖訊號32。 Taking a three-axis positioner or a gyroscope as an example, when the two electrode sheets 51 and 52 respectively cover the left and left sides of the user, or the right and right sides of the user are attached, the mobile device 6 presents a The tilting angle is measured by the detecting unit 67, and after the calculation, it is determined that the measuring device 5 is currently attached. In the user's left and left faces, or on the user's right and right faces. In this way, it can be determined that the first ECG signal 31 is currently being measured or The second electrocardiogram signal 32.
於另一實施例中，該行動裝置6還可通過內存的一應用程式662來判斷心電圖訊號的類型。具體而言，因絕大多數人的心臟偏向左邊，故如第七圖B及第七圖C所示，由使用者的左手至左邊面部的迴路量測出來的該第一心電圖訊號31，其波型一般會比由右手至右邊面部的迴路量測出來的該第二心電圖訊號32來得大。因此該行動裝置6接收該量測裝置5傳來的兩個心電圖訊號後，可以通過該應用程式662來解析該二心電圖訊號的波型特徵，藉以判斷哪一個是該第一心電圖訊號31，哪一個是該第二心電圖訊號32。 In another embodiment, the mobile device 6 can also determine the type of the electrocardiogram signal through an application 662 in the memory. Specifically, since the heart of most people is biased to the left, as shown in FIG. 7B and FIG. 7C, the first electrocardiogram signal 31 measured by the loop of the left hand to the left side of the user, The wave pattern will generally be larger than the second electrocardiogram signal 32 measured from the loop from the right hand to the right face. Therefore, after the mobile device 6 receives the two electrocardiogram signals transmitted by the measuring device 5, the waveform characterization of the two electrocardiogram signals can be analyzed by the application 662, thereby determining which one is the first electrocardiogram signal 31, which One is the second electrocardiogram signal 32.
值得一提的是，前述的該量測裝置1亦可視實際所需，設置該偵測單元67，或是安裝該應用程式662，藉此於量測過程中，判斷該量測裝置1目前量測該第一心電圖訊號31或是該第二心電圖訊號32。其詳細技術特徵與上述說明相同，故不再贅述。 It is worth mentioning that the measuring device 1 can also set the detecting unit 67 or install the application 662 according to actual needs, thereby determining the current amount of the measuring device 1 during the measuring process. The first electrocardiogram signal 31 or the second electrocardiogram signal 32 is measured. The detailed technical features are the same as those described above, and therefore will not be described again.
參閱第十三圖，為本創作的第二具體實施例的量測流程圖。首先，通過該量測裝置1、5對該使用者2進行量測，以取得一心電圖訊號(步驟S30)，接著，通過該偵測單元67或該應用程式661，判斷該心電圖訊號為量測使用者的左手至左邊面部的心電圖訊號，或是量測使用者的右手至右邊面部的心電圖訊號(步驟S32)。 Referring to the thirteenth figure, a measurement flow chart of the second embodiment of the present invention is shown. First, the user 2 is measured by the measuring device 1 and 5 to obtain an electrocardiogram signal (step S30), and then the detecting unit 67 or the application 661 determines that the electrocardiogram signal is measured. The electrocardiogram signal from the left hand to the left side of the user, or the electrocardiogram signal of the right hand to the right side of the user (step S32).
於步驟S32中判斷完成後，即可進一步量測取得另一心電圖訊號(步驟S32)，並且，通過該偵測單元67或該應用程式661，判斷該另一心電圖訊號是否相異於前一個心電圖訊號(即，步驟S30中量測的該心電圖訊號)(步驟S36)。該步驟S36的目的，在於判斷使用者是否有換邊量測，即，是否有將該量測裝置1、5從貼覆左手及左邊面部的狀態，換成貼覆右手及右邊面部的狀態(反之亦然)。藉此，可以確保量測到的兩個心電圖訊號是正確的，不是兩個該第一心電圖訊號31，也不是兩個該第二心電圖訊號32。其中，若步驟S34中量測的心電圖訊號與步驟S30中量測的心電圖訊號相同，則該量測裝置1或該行動裝置6發出提示，請求使用者重新量測(步驟S38)。 After the determination in step S32 is completed, another ECG signal can be further measured (step S32), and the detecting unit 67 or the application 661 determines whether the other electrocardiogram signal is different from the previous electrocardiogram. The signal (i.e., the electrocardiogram signal measured in step S30) (step S36). The purpose of the step S36 is to determine whether the user has the edge change measurement, that is, whether the measurement device 1, 5 is replaced from the left hand and the left face, and the right hand and the right face are attached ( vice versa). Thereby, it can be ensured that the two ECG signals measured are correct, not two of the first electrocardiogram signals 31, nor two of the second electrocardiogram signals 32. If the ECG signal measured in step S34 is the same as the ECG signal measured in step S30, the measuring device 1 or the mobile device 6 issues a prompt to request the user to re-measure (step S38).
當兩個心電圖訊號量測完畢，並且分別確認為該第一心電圖訊號31與該第二心電圖訊號32，即可如同第六圖中的步驟S14至步驟S26所示，對該二心電圖訊號31、32進行雜訊濾波處理(步驟S40)、判斷是否通過前置淘 汰處理(步驟S42)、由該二心電圖訊號31、32中分別擷取出複數心電圖特徵(步驟S46)、將該些心電圖特徵與預存的該心電圖模板151、661進行比對(步驟S48)、依據比對結果判斷該使用者2是否通過生物特徵辨識(步驟S50)、於未通過前置淘汰處理或生物特徵辨識動作時判斷為辨識失敗(步驟S44)、以及於通過辨識後，令該使用者2進行後續的動作(步驟S52)。 When the two electrocardiogram signals are measured and confirmed as the first electrocardiogram signal 31 and the second electrocardiogram signal 32, respectively, as shown in step S14 to step S26 in the sixth figure, the second electrocardiogram signal 31, 32 performs noise filtering processing (step S40), and determines whether or not the pre-sampling is passed. Step (42), extracting the plurality of electrocardiogram features from the two electrocardiogram signals 31 and 32 (step S46), comparing the electrocardiogram features with the pre-stored electrocardiogram templates 151 and 661 (step S48), and The comparison result determines whether the user 2 passes the biometric identification (step S50), determines that the identification fails if the pre-emption processing or the biometric operation is not passed (step S44), and after the identification, causes the user 2 Perform the subsequent action (step S52).
參閱第十四圖，為本創作的第一具體實施例的第三心電圖示意圖。第十四圖中揭露了前述的該第三心電圖訊號33，其中該第三心電圖訊號33可視為生物特徵辨識可使用的參數之一。然而，該第三心電圖訊號33並非直接對使用者量測所得，而是經過前文中所述的公式計算後所得出。 Referring to Figure 14, a third electrocardiogram of the first embodiment of the present invention is shown. The third electrocardiogram signal 33 is disclosed in the fourteenth figure, wherein the third electrocardiogram signal 33 can be regarded as one of the parameters that can be used for biometric identification. However, the third electrocardiogram signal 33 is not directly measured by the user, but is calculated by the formula described in the foregoing.
參閱第十五圖，為本創作的第三具體實施例的量測流程圖。若要進行最高安全等級的生物特徵辨識行為，則需盡可能地增加可供辨識的參數。本實施例中，首先該量測裝置1、5對該使用者2進行量測，以取得該完整心電圖訊號3(步驟S60)，其中該完整心電圖訊號3係由該使用者2的左手至右手的迴路來量測所得。值得一提的是，該完整心電圖訊號3亦可由其他的量測設備來進行量測，並且傳送到該量測裝置1或該行動裝置6中，不加以限定。 Referring to the fifteenth figure, a measurement flow chart of the third embodiment of the present invention is shown. To perform the biometric identification behavior of the highest security level, you need to increase the parameters that can be identified as much as possible. In this embodiment, first, the measuring device 1 and 5 measure the user 2 to obtain the complete electrocardiogram signal 3 (step S60), wherein the complete electrocardiogram signal 3 is from the left hand to the right hand of the user 2 The loop is measured. It is worth mentioning that the complete ECG signal 3 can also be measured by other measuring devices and transmitted to the measuring device 1 or the mobile device 6 without limitation.
接著，該量測裝置1、5進一步對該使用者2進行量測，以取得該第一心電圖訊號31(步驟S62)，並且取得該第二心電圖訊號32(步驟S64)。接著，該量測裝置1或該行動裝置6可依據該完整心電圖訊號3、該第一心電圖訊號31以及該第二心電圖訊號32，計算出該第三心電圖訊號33(步驟S66)。其中，該量測裝置1或該行動裝置6主要是將該完整心電圖訊號3減去該第一心電圖訊號31與該第二心電圖訊號32的訊號總合，以得出該第三心電圖訊號33。 Next, the measuring device 1 and 5 further measure the user 2 to obtain the first electrocardiogram signal 31 (step S62), and obtain the second electrocardiogram signal 32 (step S64). Then, the measuring device 1 or the mobile device 6 can calculate the third electrocardiogram signal 33 according to the complete electrocardiogram signal 3, the first electrocardiogram signal 31, and the second electrocardiogram signal 32 (step S66). The measuring device 1 or the mobile device 6 mainly subtracts the signal of the first electrocardiogram signal 31 and the second electrocardiogram signal 32 from the complete electrocardiogram signal 3 to obtain the third electrocardiogram signal 33.
值得一提的是，於本實施例中，要用以進行生物特徵辨識的心電圖訊號，總共包括了該第一心電圖訊號31、該第二心電圖訊號32及該第三心電圖訊號33，因此該量測裝置1、該行動裝置6或該伺服器42中儲存的該至少一心電圖模板151、661、421的數量必須為三個，並且分別對應至該三心電圖訊號31、32、33，如此才可以進行比對辨識。 It is to be noted that, in this embodiment, the electrocardiogram signal to be used for biometric identification includes the first electrocardiogram signal 31, the second electrocardiogram signal 32, and the third electrocardiogram signal 33, and thus the amount The number of the at least one electrocardiogram templates 151, 661, 421 stored in the measuring device 1, the mobile device 6, or the server 42 must be three, and corresponds to the three electrocardiogram signals 31, 32, 33, respectively. Perform alignment identification.
步驟S66後，即可如同第六圖中的步驟S14至步驟S26所示，對該三心電圖訊號31、32、33進行雜訊濾波處理(步驟S68)、判斷該三心電圖訊號31、 32、33是否通過前置淘汰處理(步驟S70)、由該三心電圖訊號31、32、33中分別擷取出複數心電圖特徵(步驟S74)、將該些心電圖特徵與預存的該至少一心電圖模板151、661或421進行比對(步驟S76)、依據比對結果判斷該使用者2是否通過生物特徵辨識(步驟S78)、於未通過前置淘汰處理或生物特徵辨識動作時判斷為辨識失敗(步驟S72)、以及於通過辨識後，令該使用者2進行後續的動作(步驟S80)。 After step S66, as shown in step S14 to step S26 in the sixth figure, the three electrocardiogram signals 31, 32, and 33 are subjected to noise filtering processing (step S68), and the three electrocardiogram signals 31 are determined. 32, 33 whether the plurality of electrocardiogram features are extracted from the three electrocardiogram signals 31, 32, 33 by the pre-emption processing (step S70), and the electrocardiographic features and the pre-stored at least one electrocardiogram template 151 are extracted. , 661 or 421 is compared (step S76), determining whether the user 2 passes the biometric identification according to the comparison result (step S78), and determining that the identification fails when the pre-emption processing or the biometric identification operation is not passed (step S72), and after passing the identification, the user 2 is caused to perform a subsequent operation (step S80).
值得一提的是，為了增加可供辨識的參數，該量測裝置1或該行動裝置6還可同時接收該使用者2輸入的語音訊號，並且於執行該步驟S76時，同時將該語音訊號與預先輸入的該語音資訊152進行比對。如此一來，可以更進一步提高辨識的正確率。 It is worth mentioning that, in order to increase the identifiable parameters, the measuring device 1 or the mobile device 6 can simultaneously receive the voice signal input by the user 2, and when performing the step S76, simultaneously the voice signal The voice information 152 that is input in advance is compared. In this way, the correct rate of identification can be further improved.
本創作中，主要係通過該量測裝置1、5來量測該第一心電圖訊號31與該第二心電圖訊號32，至於比對辨識的部分，以及計算該第三心電圖訊號33的部分，則可由該量測裝置1、該行動裝置6或是該伺服器42來執行，不應加以限定。 In the present invention, the first electrocardiogram signal 31 and the second electrocardiogram signal 32 are mainly measured by the measuring device 1, 5, and the portion of the comparison is calculated, and the portion of the third electrocardiogram signal 33 is calculated. It can be executed by the measuring device 1, the mobile device 6, or the server 42, and should not be limited.
