This creation is about a step frequency management device, especially a treadmill management device for treadmills.

In recent years, the national movement has become more and more popular, and the variety of sports has become more and more novel. Among them, running does not require special skills, but also can achieve the effect of exercise heart and lung function, can be said to be one of the most fitness-oriented sports. However, outdoor running sports are greatly affected by weather conditions. Therefore, treadmills that allow runners to exercise indoors are becoming more popular and popular.

When the treadmill runs on a running belt of the treadmill, the treadmill can change the movement information of the treadmill by using the weight of the athlete's body. And calculating the calculated motion information using the display device on the treadmill, thus allowing the athlete to know the condition of his or her movement.

However, when the treadmill starts to start, for example, within a few seconds after starting, if the method of detecting the current change is to calculate the number of steps, it will be caused by the unstable initial state after the start. The detected current change is susceptible to noise interference, resulting in an error in the calculation of the cumulative number of steps, reducing the accuracy of motion information calculation.

The purpose of the present invention is to provide a treadmill frequency management device for solving the transient initial instability state after the treadmill is started, so that the detected current change is susceptible to noise interference, resulting in a cumulative number of steps. Calculate the problem of an error that reduces the accuracy of motion information calculations.

In order to achieve the foregoing, the treadmill management device of the treadmill proposed by the present invention comprises a one-step sensing unit, a processing module and a human interface module. The gait sensing unit receives the one-step motion signal and converts the step signal to generate a one-step signal. The processing module includes a control unit, a counting unit, a timing unit, and a computing unit. The control unit is coupled to the gait sensing unit to receive the gait signal and output a count control signal and a timing enable signal. The counting unit is connected to the control unit to receive the counting control signal, wherein the control unit controls the counting unit to count according to the counting control signal to generate a one-step count value. The timing unit is coupled to the control unit to receive the timing enable signal, wherein the control unit activates the timing unit timing according to the timing enable signal to generate a time count value. The calculating unit is connected to the control unit to read the step count value and the time count value, and calculate a cumulative step value according to the step count value and the time count value every other time interval value And a cumulative step frequency value, wherein the step count value obtained at the beginning of one of the treadmills and the time count value are not listed as calculating the cumulative step value and the accumulated step frequency value. The human interface module includes a display unit connected to the control unit, wherein the control unit reads the accumulated step value and the accumulated step frequency value, and transmits the accumulated step value and the accumulated step frequency value To the display unit for display by the display unit.

The treadmill management device uses the "delay" and "panning" methods to calculate the exercise information of the exerciser through the calculation unit; thereby, the initial instability after the treadmill is started can be effectively removed. The state, which causes unnecessary noise interference, calculates high-accuracy motion information.

In order to further understand the techniques, means and effects of this creation in order to achieve the intended purpose, please refer to the following detailed description and drawings of this creation. I believe that the purpose, characteristics and characteristics of this creation can be obtained in this way. The detailed description is to be understood as merely illustrative and not restrictive

The technical content and detailed description of this creation are as follows.

Referring to Figures 1 and 2, the present application provides a treadmill 100 for operation and use by an athlete (user) 200. The treadmill 100 includes a running belt 101, a driving mechanism 102, and an electronic instrument panel 103. The driving mechanism 102 can be an electric motor (or a motor). The running belt 101 is driven by the driving mechanism 102 and rotated by a driving wheel (not shown) and a belt (not shown) for the athlete 200 to run or walk on. Moreover, the player 200 can control the start and stop of the treadmill 100 by controlling a human interface module 30 disposed on the electronic instrument panel 103 (refer to FIG. 3 for details). The function of the rotational speed of the driving mechanism 102, etc., and the human interface module 30 can display the motion information of the athlete 200, which will be described in detail later.

As shown in FIG. 3, the step frequency management device of the treadmill of the present invention comprises a one-step sensing unit 10, a processing module 20, and the human interface module 30. The gait sensing unit 10 can be a force sensor or a force sensor, such as a force plate or a load cell, or a pressure sensor, such as a pressure plate, for the athlete 200. The force exerted by the body on the gait sensing unit 10 when running on the running belt 101 is such that the step signal S _{FM is} a power signal in this embodiment. In conjunction with FIG. 2, the gait sensing unit 10 is disposed in a space at the bottom of the treadmill 100 and adjacent to the running belt 101. When the athlete 200 runs on the running belt 101, the gait sensing Unit 10 can sense the force applied to the athlete 200. In addition, the number of the gait sensing units 10 is not limited to one, and a plurality of gait sensing units 10 may be simultaneously disposed on the treadmill 100 to more accurately sense the power provided by the athlete 200. News. When the athlete 200 runs on the running belt 101, the gait sensing unit 10 receives the continuous one-step motion signal S _FM , and the gait sensing unit 10 converts the step signal S _FM to generate one step. State signal S _FT .

In addition, in the present invention, the gait sensing unit 10 can also be a current sensor or a voltage sensor, wherein the current sensor or the voltage sensor is disposed on the driving mechanism 102. For example, the gait sensing unit 10 can be a Hall current sensor. When the athlete 200 runs on the running belt 101, the body weight is applied to the running belt 101. The difference in variation causes the back electromotive voltage of the driving mechanism 102 to be different from the load current. Therefore, the Hall current sensor can detect the change of the load current, and detect the change of the pace of the athlete 200. The basis for the step value calculation is provided, that is, in this embodiment, the step signal S _{FM is} a current signal. Similarly, if the gait sensing unit 10 is a voltage sensor, the step signal S _{FM is} a voltage signal.

Furthermore, in the present creation, the gait sensing unit 10 can also be an infrared sensor, so that the situation of the change of the pace of the athlete 200 can be more accurately sensed. Therefore, multiple sets of infrared sensations can be installed. The detector is in an appropriate position of the treadmill 100, for example, adjacent to the platform frame of the running belt 101, and detects the change of the pace of the athlete 200 by using infrared rays to provide a basis for calculating the step value. In the example, the step signal S _{FM is} an optical signal.

The processing module 20 can be disposed in the electronic instrument panel 103 (see FIG. 2) to facilitate electrical connection with the human interface module 30. However, the position set as described above is not limited. The processing module 20 includes a control unit 21, a counting unit 22, a timing unit 23, a storage unit 24, and a computing unit 25. The control unit 21 is connected to the gait sensing unit 10 to receive the gait signal S _FT and output a counting control signal S _TC and a timing start signal S _TT .

The counting unit 22 is connected to the control unit 21 to receive the counting control signal S _TC , wherein the control unit 21 controls the counting unit 22 to count according to the counting control signal S _TC to generate a one-step count value V _C . The timing unit 23 is connected to the control unit 21 to receive the timing enable signal S _TT . The control unit 21 starts the timing unit 23 to count according to the timing enable signal S _TT to generate a time count value V _T .

The calculating unit 25 is connected to the control unit 21 to read the step count value V _C and the time count value V _T , and according to the step count value V _C and the time count value V _T , every other calculation interval The length of time of the value is calculated as a cumulative step value V _AS and a cumulative step frequency value V _AF .

The human interface module 30 includes the display unit 31. The display unit 31 is connected to the control unit 21, wherein the control unit 21 reads the accumulated step value V _AS and the accumulated step frequency value V _AF , and transmits the accumulated step value V _AS and the accumulated step frequency value V _AF The display unit 31 is provided for display by the display unit 31. As for the operation of the treadmill's stride frequency management device, a detailed description will be given later in conjunction with the drawings.

Before describing the step frequency management device of the treadmill, the "step frequency" will be described first. "Frequency", as the name suggests, refers to the frequency of running, that is, the number of steps taken in a unit of time. For example, if an athlete runs 20 steps in 10 seconds, the athlete's step frequency is 2 steps per second (2 steps/second). In addition, the pitch frequency can also be expressed in units of steps per minute. In the above example, the athlete's step frequency is 120 steps per minute (120 steps/minute).

For the sake of convenience and clarity of the technical solutions of the present invention, the specific examples illustrate, however, that the examples are not intended to limit the implementation of the present invention.         <TABLE border="1" borderColor="#000000" width="_0001"><TBODY><tr><td> time (seconds) </td><td> 0~10 </td><td> 10 ~20 </td><td> 20~30 </td><td> 30~40 </td><td> 40~50 </td><td> 50~60 </td><td> 60 ~70 </td><td> 70~80 </td></tr><tr><td> Steps</td><td> 20 </td><td> 22 </td><td > 23 </td><td> 25 </td><td> 25 </td><td> 26 </td><td> 27 </td><td> 28 </td></tr> <tr><td> Step frequency (steps/seconds) </td><td> 2.0 </td><td> 2.2 </td><td> 2.3 </td><td> 2.5 </td>< Td> 2.5 </td><td> 2.6 </td><td> 2.7 </td><td> 2.8 </td></tr></TBODY></TABLE> In this embodiment, The step frequency is calculated every 10 seconds, wherein the time period of 10 seconds is defined as a calculation interval value. However, the calculation interval value is not limited to 10 seconds, and can be changed according to actual application needs. During the period of 0 to 10 seconds, the number of steps the athlete 200 runs on the treadmill 100 is 20 steps. Therefore, the calculation unit 25 calculates the step frequency of the athlete 200 to be 2.0 steps per second. During 10 to 20 seconds, the number of steps the athlete 200 runs on the treadmill 100 is 22 steps. Therefore, the calculation unit 25 calculates the step frequency of the athlete 200 to be 2.2 steps per second. Similarly, during 20 to 30 seconds, 30 to 40 seconds, 40 to 50 seconds, 50 to 60 seconds, 60 to 70 seconds, and 70 to 80 seconds, the athlete 200 runs on the treadmill. The steps are 23 steps, 25 steps, 25 steps, 26 steps, 27 steps, and 28 steps. Therefore, the calculating unit 25 calculates that the step frequency of the athlete 200 is 2.3 steps per second and 2.5 steps per second. 2.5 steps per second, 2.6 steps per second, 2.7 steps per second, and 2.8 steps per second.       

In order to overcome the problems existing in the existing treadmill, the treadmill management device of the treadmill uses the "delay" and "panning" methods to calculate the exercise information of the athlete 200 through the calculation unit 25. The "delay" method is such that the exercise information of the athlete 200 running on it is slightly ignored at the beginning of the treadmill 100, and the so-called "translation" mode refers to when the treadmill 100 is in a steady state. After that, it is really read and calculated from the information it senses. Thereby, the initial unstable state after the treadmill 100 is started can be effectively removed, and unnecessary noise interference is caused, and high-accuracy motion information is calculated.

Therefore, in this creation, the first 10 seconds of the start count and the timekeeping operation are regarded as the initial state of the transient, and are not listed as the calculation of the effective exercise information. Here, the start count and the count operation refer to a state in which the counting unit 22 and the timing unit 23 are activated, which will be described in detail later. Moreover, after 10 seconds, the calculation of effective exercise information is started, as detailed below.

The first 10 seconds of the start count and timing operation, that is, the period of 0 to 10 seconds, is regarded as the initial period of transient. After a period of 10 seconds, that is, 10 to 20 seconds, the count value and the timer value obtained by the counting unit 22 and the timing unit 23 are calculated as the next 10 second period (that is, 20 to 30 seconds). Basis. Therefore, during 0 to 20 seconds, the display unit 31 does not display the time, step information, and/or step frequency information (hereinafter referred to as running information or sports information) of the athlete 200 running, or the display unit 31 can display Relevant reminder text in "Sports Information Calculation". Thus, after 20 seconds, the display unit 31 starts displaying the running information of the athlete 200.

If the interval displayed by the display unit 31 is 1 second, that is, the display unit 31 displays the running information of the athlete 200 once every 1 second. However, the display interval is not limited to 1 second, and the display interval can be 0.5 seconds or other seconds. Moreover, since the running information displayed by the display unit 31 is the running information of the previous time interval, that is, during the period of 20 to 30 seconds, the display unit 31 displays the calculation by the calculating unit 25 for 10-20 seconds. Running information coming out. For example, during every 20 seconds during the period of 20 to 30 seconds, the cumulative number of steps (steps) displayed by the display unit 31 are: 2 (21st second), 4 (22nd second), 7 (first) 23 seconds), 9 (24th second), 11 (25th second), 13 (26th second), 15 (27th second), 18 (28th second), 20 (29th second), and 22 (30th Seconds), as explained below. Since the display unit 31 is displayed once every one second, the cumulative number of steps displayed by the display unit 31 is 2 steps at the 21st second, and 4 steps at the 22nd second, at the 23rd second. , displayed as 7 steps, ..., and so on, at the 30th second, displayed as 22 steps. Thus, the cumulative number of steps displayed in the 30th second is 22 steps, that is, the number of steps taken by the athlete 200 in the previous time interval (10 to 20 seconds). Wherein, since the step value is a positive integer value, the calculation of the step information can be rounded to the integer number of digits.

The following 10 seconds is taken as an example. During the period of 30 to 40 seconds, the number of accumulated steps (steps) displayed by the display unit 31 is: 24 (31st second), 27 (32th second), 29 (33rd second), 31 (34th second), 34 (35th second), 36 (36th second), 38 (37th second), 40 (38th second), 43 (39th second), and 45 (40th second), description as follows. Since the display unit 31 is displayed once every one second, the total number of steps displayed by the display unit 31 is 24 steps at the 31st second, and 27 steps at the 32nd second, at the 33rd second. , displayed as 29 steps, ..., and so on, at the 40th second, displayed as 45 steps. Thus, the cumulative number of steps displayed in the 40th second is 45 steps, that is, the number of steps that the athlete 200 ran in the last two time intervals (10 to 30 seconds). So, and so on.

Furthermore, the calculation unit 25 can also calculate the cumulative step frequency, starting from the effective calculation time. In the embodiment, the effective calculation time is 0 to 10 seconds, according to the athlete 200. The cumulative step frequency can be calculated by the cumulative number of steps run. For example, during 20 to 30 seconds, the display unit 31 displays the running information calculated by the calculating unit 25 during 10 to 20 seconds. That is, during the period of 20 to 30 seconds, the cumulative step frequency calculated by the calculation unit 25 is calculated as the cumulative number of steps during the period of 10 to 20 seconds and the effective accumulated time. Therefore, during the period of 20 to 30 seconds, In 1 second, the cumulative step frequency displayed by the display unit 31 is 132.0 (steps/minute), that is, 22×60/10=132.0. Similarly, during every 30 seconds, the cumulative step frequency displayed by the display unit 31 is 135.0 (steps/minute), that is, 45×60/20=135.0. Similarly, during the period of 40 to 50 seconds, every 1 second, the cumulative step frequency displayed by the display unit 31 is 140.0 (steps/minute), that is, 70×60/30=140.0. So, and so on.

In summary, the running information of the athlete 200 can be calculated by the calculating unit 25 and displayed in conjunction with the display unit 31. As shown in FIG. 4A, the information that the display unit 31 can display is as shown in the figure, and may include "Step time", "cumulative step" and "cumulative step" are not limited to the above information. The "step time" is the aforementioned effective calculation time. For example, the information shown in FIG. 4A corresponds to the information during the period of 50 to 60 seconds. Therefore, the effective calculation time should be deducted from the first 20 seconds of the "delay" and "translation" modes. Thus, when the timer unit 23 counts the 60th second, the effective "step time" displayed by the display unit 31 should be 40 seconds. Thus, at the 40th second, the value displayed by the "cumulative step number" is For 20~60 seconds, the cumulative number of steps between these 40 seconds is 95 steps. Moreover, at the 40th second, the value displayed by the "cumulative step frequency" is the frequency of 95 steps between 40 seconds, which is 142.5 (steps/minute), which is 95×60/40=142.5.

Similarly, as shown in FIG. 4B, the information displayed is corresponding to the information during the period of 60 to 70 seconds. Therefore, the effective calculation time should be deducted from the first 20 seconds. Thus, when the timekeeping unit 23 counts the 70th second, the effective "step time" displayed by the display unit 31 should be 50 seconds. Thus, at the 50th second, the value displayed by the "cumulative step number" is For 20~70 seconds, the cumulative number of steps between these 50 seconds is 121 steps. Moreover, at the 50th second, the value displayed by "cumulative step frequency" is the frequency of running 121 steps in 50 seconds, which is 145.2 (steps/minute), which is 121 × 60 / 50 = 145.2.

Furthermore, as shown in FIG. 4C, the information displayed is corresponding to the information during the period of 70 to 80 seconds. Therefore, the effective calculation time should be deducted from the first 20 seconds. Thus, when the timekeeping unit 23 counts the 80th second, the effective "step time" displayed by the display unit 31 should be 60 seconds. Thus, at the 60th second, the value displayed by the "cumulative step number" is For 20~80 seconds, the cumulative number of steps between 60 seconds is 148 steps. Moreover, at the 60th second, the value displayed by the "accumulated step frequency" is the frequency of 148 steps between 60 seconds, which is 148.0 (steps/minute), which is 148 x 60/60 = 148.0.

Taking FIG. 5A to FIG. 5C as an example, FIG. 5A shows the motion information when the effective calculation time is the 50th second, including “count step time” is displayed as 00:00:51, and “cumulative step” is displayed as step 0124 and The "cumulative step frequency" is displayed as 145.9 steps/minute, as illustrated in Figure 4B. Figure 5B shows the motion information when the effective calculation time is 51 seconds, including "step time" displayed as 00:00:51, "cumulative step" is displayed as 0124, and "cumulative step" is displayed as step 145.9. /minute. Among them, the "cumulative step number" is 124 steps, which is 121 + 27/10 × 1, and then rounded to the integer number of digits, which can be obtained 124. In the above formula, 121 represents the cumulative number of steps during the period of 20 to 70 seconds, and 27 represents a total of 27 steps during the period of 60 to 70 seconds. ×1 indicates that 50 to 51 intervals are 1 second. Thus, from 50 seconds to 51 seconds, "cumulative The number of steps is changed from 121 steps to 124 steps. Furthermore, the "cumulative step frequency" is 145.9 steps / minute, which is 124 × 60 / 51, and then rounded to the first decimal place, you can get 145.9. In the above formula, 124 represents the cumulative number of steps during the period of 20 to 71 seconds. Thus, in the case where the accumulated effective time is 51 seconds and the process runs for 124 steps, the calculation unit 25 can calculate the "cumulative step frequency" of 145.9 steps / minute.

Similarly, FIG. 5C shows the motion information when the effective calculation time is 52 seconds, including "step time" displayed as 00:00 minutes and 52 seconds, "cumulative step number" is displayed as 0126 steps, and "cumulative step frequency" Displayed as 145.4 steps / minute. Among them, the "cumulative step number" is 126 steps, which is 121 + 27/10 × 2, and then rounded to the integer number of digits, which can be obtained 126. In the above formula, 121 represents the cumulative number of steps during the period of 20 to 70 seconds, 27 represents a total of 27 steps during the period of 60 to 70 seconds, and ×2 represents 50 to 52 intervals of 2 seconds, thus, from 51 seconds to 52 seconds, "cumulative The number of steps is changed from 124 steps to 126 steps. Furthermore, the "cumulative step frequency" is 145.4 steps / minute, which is 126 × 60 / 52, and then rounded to the first decimal place, you can get 145.4. In the above formula, 126 represents the cumulative number of steps during the period of 20 to 72 seconds. Thus, in the case where the accumulated effective time is 52 seconds and the process runs 126 steps, the calculation unit 25 can calculate the "cumulative step frequency" of 145.4 steps / minute.

Taking FIG. 6A to FIG. 6C as an example, when the athlete 200 continuously runs, the movement can be calculated according to the number of steps run by the athlete 200 and the accumulated effective time according to the corresponding cumulative time interval. The sports information of the 200 long-distance running. As shown in FIG. 6A, the motion information when the effective calculation time is 15 minutes and 00 seconds is displayed, including "step time" displayed as 00 hours, 15 minutes and 00 seconds, "cumulative steps" displayed as 2408 steps, and "cumulative steps". The frequency is displayed as 160.5 steps/minute. When the athlete 200 continues to run, as shown in FIG. 6B, the effective calculation time is displayed as the motion information at the 15th minute and 30 seconds, including the "step time" displayed as 00 hours, 15 minutes and 30 seconds, "cumulative step" The number is displayed as step 2491 and the "cumulative step frequency" is displayed as 160.7 steps/minute. Similarly, as shown in FIG. 6C, the motion information when the effective calculation time is 16 minutes and 00 seconds is displayed, and the "step time" is displayed as 00:16:00, and the "cumulative step" is displayed as 2569 steps. The "cumulative step frequency" is displayed as 160.6 steps/minute.

The display unit 31 can provide not only the motion information of the athlete 200 in text form as shown in FIG. 4A to FIG. 6, but also the motion information of the athlete 200 in an image manner. As shown in FIG. 7, on the display unit 31, not only the latest motion information can be displayed, for example, the step time is 00:16:00, the accumulated step is 2569, and the accumulated step is 160.6/min. The motion information history of the athlete 200, such as the history of the accumulated step frequency, can be further represented graphically. Thereby, by displaying the motion information history, it is helpful to help the athlete 200 to continuously observe the cumulative cadence state of the long-term motion process. For a long-distance runner, to be able to run good grades, you must pay attention to the improvement of the pace, because the increase in the pace represents the increase in speed. Together with the stable step frequency, it shows that the long-distance runner has a stable and high-speed long-distance running ability. However, the increase in the step frequency requires long-term training for the long-distance runners, and the step frequency can be gradually increased to effectively increase the speed. In this way, the motion information history provided by the display unit 31 of the present invention will help the athlete 200 to enhance the step frequency and stabilize the training, and the motion information history is presented through the image mode, which is helpful to the athlete 200. The cumulative pitch information from the beginning to the present can be visually observed, and the fun and motivation of using the treadmill 100 can be improved. Furthermore, the present invention can provide not only the above display manner, but also further providing the sports information in a variety of ways in the form of sound, light or other forms. For example, when the athlete 200 continues to run for more than a predetermined time, or the accumulated step exceeds a predetermined value, or the accumulated step frequency exceeds a predetermined value, the treadmill 100 may A reminder sound or music is emitted through the speaker, or light of a different color can be emitted through a light-emitting element such as a light-emitting diode to improve the fun of the athlete 200 using the treadmill 100, chasing the power of setting a target, or achieving a set target A sense of accomplishment.

4A to 7 are illustrated by way of example. Next, the operation of the treadmill management device of the treadmill will be further described in conjunction with the aforementioned examples.

As shown in FIG. 1, FIG. 2 and FIG. 3, the athlete 200 (user) first stands on the running belt 101 of the treadmill 100, and then turns on a power switch disposed on the electronic instrument panel 103. (not shown) to activate the drive mechanism 102 of the treadmill 100, such as a motor, to drive the running belt 101 to begin to accelerate. The operator 200 can operate the control unit 32 of the human interface module 30 to generate a control signal S _OC , wherein the control signal S _OC is transmitted to the control module 20 . The unit 21, in turn, adjusts the rotational speed of the drive mechanism 102 to control the speed of the treadmill 100 such that, after a few seconds, the drive mechanism 102 will gradually accelerate from a stationary state to a rotational speed adjusted by the athlete 200.

After the athlete 200 activates the treadmill 100, and after the athlete 200 starts running, when the gait sensing unit 10 detects the first step signal S _FM , the processing module is turned on. 20 operations. Wherein, if the gait sensing unit 10 is a power sensor or a pressure sensor, the step signal S _FM is a power signal; if the gait sensing unit 10 is a current sensor or In the case of a voltage sensor, the step signal S _FM is a current signal or a voltage signal. Further, if the gait sensing unit 10 is an infrared sensor, the step signal S _FM is a light. signal. As shown in FIG. 8 , specifically, when the gait sensing unit 10 detects the first step signal S _FM ( S11 ), the gait sensing unit 10 converts the first step. Signal S _{FM is used} to generate a first one of the gait signals S _FT (S12). The gait sensing unit 10 outputs the gait signal S _FT to the control unit 21 of the processing module 20 (S13).

When the control unit 21 receives the first gait signal S _FT , the control unit 21 outputs the counting control signal S _TC to the counting unit 22 (S14) and outputs the timing starting signal S _TT to the timing unit. 23 (S15). The step (S14) and the step (S15) are not limited by the above sequence, that is, the step (S15) may be performed earlier than the step (S14). When the counting unit 22 receives the count control signal S _TC , the counting operation is performed (S16). When the control unit 21 outputs the count control signal S _{TC each} time, the function of counting up by the counting unit 22 is performed. For example, when the gait sensing unit 10 detects 20 step signals S _FM for a period of time, the gait sensing unit 10 sequentially converts the 20 step signals S _FM to 20 gait signals S _FT . When receiving each gait signal S _FT , the control unit 21 correspondingly outputs the counting control signal S _TC to control the counting unit 22 to accumulate the step count value V _C . Therefore, the gait sensing unit 10 detects 20 step signals S _FM , and the step count value V _C generated by the counting unit 22 is incremented to 20. When the timing unit 23 receives the timing enable signal S _TT , the timing unit 23 is started to start counting, and the timing unit 23 is caused to accumulate the time count value V _T (S17).

The calculation unit 25 calculates the movement information of the number of steps and the step frequency every 10 seconds in accordance with the examples of FIG. 4A to FIG. 7 and the corresponding description. However, the practical application does not limit the time by 10 seconds. Therefore, in the following description, this 10-second time period is defined as the calculation interval value. Furthermore, for the sake of brevity and clarity of the operation of the calculation unit 25, the principles of calculation described below are as shown in FIGS. 3A to 7 and the corresponding description. As shown in FIG. 9, when the timing unit 23 counts up to the calculation interval value (S21), that is, when the timing reaches 10 seconds, the timing unit 23 outputs a calculation start signal S _CS to the control unit 21 (S22). The calculation unit 21 is controlled to notify the calculation unit 25 to calculate the cumulative step value and the accumulated step frequency value, which will be described in detail later. After the control unit 21 receives the calculation start signal S _CS , the control unit 21 outputs a value transfer signal S _VT to the counting unit 22 and the timing unit 23 (S23) to notify the counting unit 22 and the timing unit. The step count value V _C and the time count value V _{T are} transmitted to the storage unit 24. At the same time, the control unit 21 also outputs a calculation control signal S _CC to the calculation unit 25 to notify the calculation unit 25 to read the step count value V _C and the time count value V _T . The step (S23) and the step (S24) are not limited by the above sequence, that is, the step (S24) may be performed earlier than the step (S23).

When the counting unit 22 receives the value transmission signal S _VT , the counting unit 22 transmits the step count value V _C to the storage unit 24 (S25), for the storage unit 24 to store the step count value V. _C. When the timing unit 23 receives the value transmission signal S _VT , the timing unit 23 transmits the time count value V _T to the storage unit 24 (S26) for the storage unit 24 to store the time count value V _T . The step (S25) and the step (S26) are not limited by the above sequence, that is, the step (S26) may be performed earlier than the step (S25).

When the calculation unit 25 receives the calculation control signal S _CC , the calculation unit 25 reads the step count value V _C stored by the storage unit 24 and the time count value V _T (S27). It should be noted that, as described in the foregoing example, in the step (S27), the step count value V _C read by the calculating unit 25 and the time count value V _T are the previous time interval. The step count value V _C is the time count value V _T . In other words, in step (S25), the counting unit 22 transmits the step count value V _C stored in the storage unit 24, and in the step (S26), the timing unit 23 transmits to the storage unit 24 to store The time count value V _T , the step count value V _C and the time count value V _T are read by the calculation unit 25 in the latter time interval, and subsequent calculation information is performed. Therefore, in the step (S27), the computing unit 25 reads the count value of the step count value V _T V _C and the time is based pedometer value V _C and V before the time count value of the time interval _T , as a follow-up calculation.

When the calculating unit 25 receives the step count value V _C of the previous time interval and the time count value V _T , the calculated value is based on the step count value V _C and the time count value V _T The effective accumulated time can be calculated as the current accumulated step value V _AS and the accumulated step frequency value V _AF . The effective accumulated time is the aforementioned step time, which is the first 20 seconds after the "time delay" and "translation" modes are deducted from the accumulated time after the timekeeping unit 23 starts. The calculation of the cumulative step value V _AS and the cumulative step frequency value V _AF can be described in conjunction with the corresponding description in the examples listed in FIGS. 3A to 6C , and details are not described herein again.

As shown in FIG. 10, when the calculating unit 25 calculates the accumulated step number and the accumulated step frequency based on the step count value and the time count value of the previous time interval (S31), the calculating unit 25 transmits the cumulative step. The number is accumulated to the storage unit 24 (S32), and a calculation completion signal S _CD is outputted to the control unit 21 (S33) to notify the control unit 21 that it has completed the calculation, ready to read the calculation result. When the control unit 21 receives the calculation completion signal S _CD , the control unit 21 reads the accumulated step number from the storage unit 24 and the accumulated step frequency (S34). When the control unit 21 receives the accumulated step value V _AS and the accumulated step frequency value V _AF , the control unit 21 transmits the received accumulated step value V _AS and the accumulated step frequency value V _AF to the display unit 31 ( S35) In this manner, the display unit 31 displays the accumulated step value V _AS and the accumulated step frequency value V _AF (S36) for the athlete 200 to exercise information.

In addition, the treadmill 100 further provides the function of automatically shutting down. When the athlete 200 finishes using the treadmill 100, the power switch on the electronic dashboard 103 can be manually turned off, causing the treadmill 100 to gradually decelerate and eventually stop operating. However, if the athlete 200 does not actively turn off the power switch after using the treadmill 100, the treadmill 100 is continuously in operation, and if other users accidentally touch the still-operating one, Running the belt 101 will cause an injury to occur. Therefore, the treadmill 100 can continuously sense the step signal S _FM through the gait sensing unit 10. If the gait sensing unit 10 continues for a period of time, for example, 10 seconds or 20 seconds, but is not limited _thereto , when the step signal S _FM is not received, it is determined that the treadmill 100 is currently unmanned. State, therefore, the power is turned off, causing the treadmill 100 to stop operating.

In summary, this creation has the following features and advantages:

1. The motion information of the athlete 200 is calculated by the calculation unit 25 by means of "delay" and "translation", whereby the initial unstable state after the treadmill 100 is started can be effectively removed, resulting in unnecessary The noise interferes with the calculation of high-accuracy motion information.

2. The display unit 31 displays the motion information of the athlete 200 through text or image, which helps the athlete 200 to improve the training effect and power of the step frequency; and further provides sound, light or other forms. In a manner, the sports information is presented in a variety of ways to improve the running pleasure of the athlete 200.
