Description
本創作是一種檢測裝置，特別是指身體訓練器的運動狀態檢測裝置。The present invention is a detecting device, in particular, a motion state detecting device of a body trainer.
對一般人而言，運動的好處可以增強心肺功能，並可促進血液循環，使人健康；對於復健中的患者來說，係可藉由運動來恢復體力與肌力。運動大致上可分為室外運動與室內運動，為了要在有限的室內空間內運動，目前健身房或復健醫院皆設有各種身體訓練器，例如跑步機、健身車或橢圓機等，使用者亦可自行購買身體訓練器置放在家裡，讓使用者在家也能進行健身運動。For the average person, the benefits of exercise can enhance heart and lung function, and promote blood circulation, making people healthy; for patients in rehabilitation, the body and muscle strength can be restored by exercise. Sports can be broadly divided into outdoor sports and indoor sports. In order to exercise in a limited indoor space, the gym or rehabilitation hospitals currently have various body trainers, such as treadmills, exercise bikes or elliptical machines. Self-purchasing body trainers can be placed at home so that users can exercise at home.
現有身體訓練器大都設有偵測元件，偵測元件所測得的信號傳送至一運算裝置進行運算，運算裝置之運算結果可供使用者得知本身的運動狀態。Most of the existing body trainers are provided with a detecting component, and the signal measured by the detecting component is transmitted to an arithmetic device for calculation, and the operation result of the computing device is available for the user to know the motion state of the user.
然而，已知單一種偵測元件大都只能檢測到單一種運動資訊，例如轉速偵測元件能偵測轉速，方向偵測元件僅能偵測方向，當要同時偵測轉速與方向時，必須同時安裝轉速偵測元件與方向偵測元件。由此可見，當要得到多種運動資訊時，必須安裝多個偵測元件，導致偵測元件佔用身體訓練器的空間，並使信號線或電力線的線路配置會變得更複雜、組裝不易。However, it is known that a single type of detecting component can only detect a single motion information. For example, the speed detecting component can detect the rotational speed, and the direction detecting component can only detect the direction. When the rotational speed and the direction are simultaneously detected, At the same time, the rotation detecting component and the direction detecting component are installed. It can be seen that when multiple motion information is required, multiple detection components must be installed, which causes the detection component to occupy the space of the body trainer, and the line configuration of the signal line or the power line becomes more complicated and the assembly is not easy.
本創作的主要目的是提供一種身體訓練器的運動狀態 檢測裝置，利用簡單的結構達到檢測多種運動狀態的目的。The main purpose of this creation is to provide a movement state of the body trainer. The detecting device achieves the purpose of detecting a plurality of motion states with a simple structure.
本創作檢測裝置係應用於身體訓練器之一本體與一運動裝置，該檢測裝置包含有：一受測元件，設置在該運動裝置上以沿著一循環的運動軌跡移動；複數個感應元件，沿著該運動軌跡設置在該本體上，該受測元件相對該些感應元件移動，各感應元件係感應到受測元件後產生一感應信號；以及一控制器，電連接該些感應元件以接收感應信號，該控制器將該運動軌跡區分為複數個軌跡區段，並根據該些感應信號在各軌跡區段中彼此間隔的時間判斷使用者的運動狀態。The creation detecting device is applied to a body of a body trainer and a moving device, and the detecting device comprises: a measuring component disposed on the moving device to move along a circular motion track; a plurality of sensing elements, Positioned along the movement track on the body, the device under test moves relative to the sensing elements, each sensing element senses an inductive signal after sensing the device under test; and a controller electrically connects the sensing elements to receive Inductive signal, the controller divides the motion trajectory into a plurality of trajectory segments, and determines a motion state of the user according to the time at which the sensing signals are spaced apart from each other in each trajectory segment.
本創作只需要將該些感應元件固設在身體訓練器的本體上，且將受測元件設置在運動裝置上，例如感應元件可設於健身車的車架上，受測元件可設於曲柄上，當使用者踩踏曲柄時，該受測元件即可沿著圓形的運動軌跡移動，當受測元件經過感應元件時，感應元件即可對應產生感應信號。The present invention only needs to fix the sensing elements on the body of the body trainer, and set the device under test on the moving device. For example, the sensing element can be set on the frame of the exercise bike, and the device under test can be set on the crank. In the above, when the user steps on the crank, the device under test can move along a circular motion trajectory, and when the device under test passes through the sensing component, the sensing component can generate an induced signal correspondingly.
當該控制器接收到感應信號後，可根據兩感應元件的間隔時間即可推算出運動裝置的轉速，可根據所接收到感應信號的排列順序判斷出運動裝置是正轉或逆轉，還可根據軌跡區段分別判斷使用者之左、右腳(或左、右手)的運動狀態。After the controller receives the sensing signal, the rotation speed of the motion device can be estimated according to the interval time of the two sensing elements, and the motion device can be determined to be forward or reverse according to the order of the received sensing signals, and can also be based on the trajectory. The segments determine the motion state of the user's left and right feet (or left and right hands), respectively.
是以，該控制器可同時判斷出多種運動狀態，本創作 結構主要包含的元件僅有受測元件、感應元件與控制器，故本創作的構造相當簡單而可有效簡化線路的配置，並使組裝變得容易。Therefore, the controller can simultaneously determine a variety of motion states, this creation The structure mainly includes only the components to be tested, the sensing component and the controller, so the structure of the creation is quite simple, which can simplify the configuration of the circuit and make the assembly easy.
請參考圖1、2所示，本創作之檢測裝置係裝設在一身體訓練器上，身體訓練器可為健身車或橢圓機，該身體訓練器主要包含有一本體與一設置在該本體上的運動裝置，該運動裝置係沿著循環的運動軌跡相對該本體運動。Referring to FIG. 1 and FIG. 2, the detecting device of the present invention is installed on a body trainer, and the body trainer can be an exercise bike or an elliptical machine. The body trainer mainly includes a body and a body disposed thereon. The motion device moves relative to the body along a trajectory of the cycle.
身體訓練器以健身器為例，該本體為車架10，該運動裝置包含有齒盤11、鏈條12、兩曲柄13與飛輪14，當使用者踩踏曲柄13運動時，曲柄13透過齒盤11與鏈條12帶動飛輪14轉動。The body trainer is exemplified by an exercise machine. The body is a frame 10, and the movement device comprises a toothed disc 11 , a chain 12 , two cranks 13 and a flywheel 14 . When the user steps on the crank 13 , the crank 13 passes through the toothed disc 11 . The chain 12 drives the flywheel 14 to rotate.
本創作之檢測裝置包含有一檢測單元20與一控制器30，該檢測單元20設置在該車架10的一側，假設使用者左腳所踩踏的曲柄13上設有該檢測單元20。該檢測單元20包含有複數個感應元件21~24與一受測元件25。The detecting device of the present invention comprises a detecting unit 20 and a controller 30. The detecting unit 20 is disposed on one side of the frame 10, and the detecting unit 20 is provided on the crank 13 on which the user's left foot is stepped on. The detecting unit 20 includes a plurality of sensing elements 21-24 and a measuring component 25.
該受測元件25可為永久磁鐵或發光二極體(LED)，本實施例是以永久磁鐵為例。該受測元件25是固設在該曲柄13上，請參考圖3所示，當使用者踩踏曲柄13運動時，該曲柄13係以一軸心A相對該車架10轉動，使該受測元件25沿著一循環的運動軌跡40移動。The device under test 25 can be a permanent magnet or a light emitting diode (LED). In this embodiment, a permanent magnet is taken as an example. The device under test 25 is fixed on the crank 13. Referring to FIG. 3, when the user steps on the crank 13, the crank 13 is rotated relative to the frame 10 by an axis A, so that the test is performed. Element 25 moves along a cycle of motion trajectory 40.
該些感應元件21~24可為霍耳元件或感光元件，本實施例是以霍耳元件為例。該些感應元件21~24分別透過電路板固設在該車架10上且對應該受測元件25之運動軌跡40的位置，各感應元件21~24係根據感應到的磁場而產生 一感應信號S。是以，當使用者踩踏曲柄13運動時，該受測元件25係沿著運動軌跡40依序經過該些感應元件21~24，使該些感應元件21~24依序產生感應信號S1 ~S4 。The sensing elements 21 to 24 may be Hall elements or photosensitive elements. This embodiment is exemplified by a Hall element. The sensing elements 21-24 are respectively fixed on the frame 10 through the circuit board and corresponding to the position of the motion track 40 of the device under test 25, and each of the sensing elements 21-24 generates an inductive signal according to the induced magnetic field. S. Therefore, when the user steps on the crank 13 to move, the device under test 25 sequentially passes through the sensing elements 21-24 along the motion track 40, so that the sensing elements 21~24 sequentially generate the sensing signals S 1 ~ S 4 .
前述受測元件25與感應元件21~24的位置僅是較佳實施例而已，並不用來限制本創作。受測元件25可設置在齒盤11或飛輪14上，以隨著齒盤11或飛輪14的轉動而移動，該感應元件21~24則可設置在車架10上對應受測元件25的位置，以感應受測元件25的磁場。此外，當感應元件21~24分佈的密度越高，該控制器30所判斷出的數據係更加精確，本較佳實例僅以四個感應元件21~24為例說明。The positions of the above-mentioned device under test 25 and the sensing elements 21 to 24 are only preferred embodiments and are not intended to limit the present invention. The device under test 25 can be disposed on the spur 11 or the flywheel 14 to move with the rotation of the spur 11 or the flywheel 14, and the sensing elements 21-24 can be disposed on the frame 10 corresponding to the position of the device under test 25. To sense the magnetic field of the device under test 25. In addition, when the density of the sensing elements 21 to 24 is higher, the data judged by the controller 30 is more accurate. The preferred embodiment is described by taking only four sensing elements 21 to 24 as an example.
該控制器30電連接該些感應元件21~24以接收感應信號，該控制器30並根據該些感應信號的時間點判斷該身體訓練器的運動狀態。請參考圖3所示，本較佳實施例中，該運動軌跡40可區分為等長的第一~第四軌跡區段41~44，該檢測單元20包含有一第一~第四感應元件21~24，該四個感應元件21~24分別設置在該些區段41~44上。The controller 30 is electrically connected to the sensing elements 21 to 24 to receive the sensing signals, and the controller 30 determines the motion state of the body trainer according to the time points of the sensing signals. Referring to FIG. 3, in the preferred embodiment, the motion track 40 can be divided into first to fourth track segments 41-44 of equal length, and the detecting unit 20 includes a first to fourth sensing elements 21 ~24, the four sensing elements 21~24 are respectively disposed on the sections 41-44.
當使用者踩踏曲柄13運動時，該受測元件25依序經過該些感應元件21~24，當受測元件25沿著運動軌跡40運動一圈後，該些感應元件21~24分別依序產生第一~第四檢測信號S1 ~S4 。該控制器30係將兩檢測信號之間隔時間依序定義為一第一時間T1(秒)、一第二時間T2(秒)、一第三時間T3(秒)與一第四時間T4(秒)，第一時間T1代表 受測元件25經過第一軌跡區段41所花費的時間，依此類推。When the user steps on the crank 13 to move, the device under test 25 sequentially passes through the sensing elements 21-24. When the device under test 25 moves along the motion track 40, the sensing elements 21-24 are sequentially followed. The first to fourth detection signals S 1 to S 4 are generated. The controller 30 sequentially defines the interval between the two detection signals as a first time T1 (seconds), a second time T2 (seconds), a third time T3 (seconds), and a fourth time T4 (seconds). The first time T1 represents the time it takes for the device under test 25 to pass the first trajectory section 41, and so on.
是以，當該控制器30取得第一~第四時間T1~T4後，係將該些時間加總為一總時間T(s)，T=T1+T2+T3+T4，該控制器30係根據該總時間T計算出該曲柄13的轉速RPM，RPM=60/T。是以，本創作只要利用一個檢測單元20即可判斷出曲柄13的轉速RPM，代表使用者踩踏曲柄13的速度。Therefore, after the controller 30 obtains the first to fourth times T1 to T4, the time is added to a total time T(s), T=T1+T2+T3+T4, and the controller 30 Based on the total time T, the rotational speed RPM of the crank 13 is calculated, RPM = 60/T. Therefore, the present invention can determine the rotational speed RPM of the crank 13 by using one detecting unit 20, which represents the speed at which the user steps on the crank 13.
該控制器30除了可判斷轉速，還可根據接收到感應信號的排列順序判斷曲柄13的正、反轉。舉例來說，當該控制器30依序接收到該些感應信號(.-Sn -S1 -S2 -Sn-1 -Sn -S1 -S2 -.，n為感應元件的數量，本實施例中，n=4)，即該第一~第四感應信號為正向排列(.-S4 -S1 -S2 -S3 -S4 -.)，該控制器30可判斷該曲柄13為正轉；相反的，當該控制器30依序接收到第四~第一感應信號(-S4 -S3 -S2 -S1 -S4 -.)，即該第一~第四感應信號為反向排列(-S1 -Sn -Sn-1 - -S2 -S1 -Sn -.)，該控制器30可判斷該曲柄13為反轉。In addition to the determination of the number of revolutions, the controller 30 can determine the forward and reverse of the crank 13 based on the order in which the sensing signals are received. For example, when the controller 30 sequentially receives the sensing signals (.-S n -S 1 -S 2 -S n-1 -S n -S 1 -S 2 -., n is an inductive element The number, in this embodiment, n=4), that is, the first to fourth sensing signals are forward arrayed (.-S 4 -S 1 -S 2 -S 3 -S 4 -.), the controller 30 It can be judged that the crank 13 is forward rotation; conversely, when the controller 30 sequentially receives the fourth to first sensing signals (-S 4 -S 3 -S 2 -S 1 -S 4 -.), that is, The first to fourth sensing signals are arranged in the reverse direction (-S 1 -S n -S n-1 - -S 2 -S 1 -S n -.), and the controller 30 can judge that the crank 13 is inverted.
進一步，該控制器30可根據感應信號分別判斷使用者左、右腳的施力程度。承前述，使用者左腳所踩踏的曲柄13上設有該檢測單元20，一般來說，左腳在第一與第二軌跡區段41、42中為由上而下踩踏而容易施力，該控制器30可根據第一時間與第二時間的總和TL，TL=T1+T2，判斷出左腳的轉速RPML，；同理， 左腳在第三與第四軌跡區段43、44中僅是被曲柄13帶動往上牽引，即右腳在這兩軌跡區段43、44中為由上而下踩踏施力，因此該控制器30可根據第三時間與第四時間的總和TR，TR=T3+T4，判斷出右腳的轉速RPMR，。該控制器30即可根據左腳與右腳的轉速RPML、RPMR判斷出左右腳的施力程度，當轉速越高，代表施力程度越大。Further, the controller 30 can determine the degree of force applied to the left and right feet of the user according to the sensing signal. In the foregoing, the detecting unit 20 is disposed on the crank 13 on which the user's left foot is stepped. Generally, the left foot is easily biased in the first and second trajectory sections 41 and 42 from the top to the bottom. The controller 30 can determine the rotational speed RPML of the left foot according to the total TL of the first time and the second time TL, TL=T1+T2, Similarly, the left foot is only pulled up by the crank 13 in the third and fourth track sections 43, 44, that is, the right foot is stepped from top to bottom in the two track sections 43, 44. Therefore, the controller 30 can determine the rotational speed RPMR of the right foot according to the sum of the third time and the fourth time TR, TR=T3+T4, . The controller 30 can determine the degree of force applied to the left and right feet according to the rotational speeds RPML and RPMR of the left and right feet, and the higher the rotational speed, the greater the degree of exertion.
該控制器30還可根據第一~第四時間T1~T4之長短分別判斷左、右腳的作功狀態，即是否減緩或停止施力。於第一與第二軌跡區段41、42中，若第二時間T2較第一時間T1長(T2>T1)，代表左腳在第二軌跡區段42中的施力程度已減輕或停止施力；同理，若第四時間T4較第三時間T3長(T4>T3)，代表右腳在第四軌跡區段44施力程度已減輕或停止施力。The controller 30 can also determine the working state of the left and right feet according to the lengths of the first to fourth times T1 to T4, that is, whether to slow or stop the applying force. In the first and second trajectory sections 41, 42, if the second time T2 is longer than the first time T1 (T2>T1), the degree of exertion of the left foot in the second trajectory section 42 has been reduced or stopped. Similarly, if the fourth time T4 is longer than the third time T3 (T4>T3), it means that the right foot is relieved or the force is applied in the fourth track section 44.
再者，使用者可在感興趣的軌跡區段中設置較多的感應元件。舉例來說，請參考圖4所示，以第一軌跡區段41為例，當使用者要特別檢測左腳在第一軌跡區段41的運動狀態，可在第一軌跡區段41中再設置多個感應元件26~29，使第一軌跡區段41中感應元件的密度在高於其他軌跡區段42~44，由於第一軌跡區段41中感應元件的密度較高，故該控制器30可從第一軌跡區段41獲得更多感應信號，使得檢測結果更為精密與準確。Furthermore, the user can set more sensing elements in the track segment of interest. For example, referring to FIG. 4, taking the first trajectory section 41 as an example, when the user wants to specifically detect the motion state of the left foot in the first trajectory section 41, the first trajectory section 41 can be further The plurality of sensing elements 26-29 are disposed such that the density of the sensing elements in the first track section 41 is higher than the other track sections 42-44, and the control is higher due to the higher density of the sensing elements in the first track section 41. The device 30 can obtain more sensing signals from the first track segment 41, so that the detection result is more precise and accurate.
綜上所述，本創作之檢測裝置結構簡單而易於實施，控制器30所判斷出的轉速資訊反映使用者的作功程度， 故使用者得以瞭解自己的體能狀態，並適時地調整自己的運動節奏與強度。In summary, the detection device of the present invention is simple in structure and easy to implement, and the rotation speed information judged by the controller 30 reflects the degree of work of the user. Therefore, users can understand their physical status and adjust their rhythm and intensity in a timely manner.
