The invention relates to a treadmill and a track control method thereof, and in particular to a treadmill and a track control method thereof that determine the imaging length of a light pattern in a signal providing element through a controller to adjust the track.

In recent years, Chinese people have paid more attention to the importance of health, and a wave of sports has emerged. At present, the most popular sports fitness equipment is mainly treadmills. In order to allow users to have more diversified choices, the treadmill can provide different setting functions such as speed change, timing, and multi-sport mode, so that the user can adjust the exercise state as needed.

When the conventional treadmill adjusts the track, the user often needs to directly press the control panel to select and give instructions. However, the user's physical strength will be gradually lost as the exercise time lengthens, causing the user to become increasingly unable to keep up with the speed of the runway rotation. Therefore, the user will be located in the second half of the runway far from the control panel. In this case, it is very likely that the user will not press the selection command or the function of emergency power-off may cause accidents.

In addition, most users have inertial motion postures. For example, the user may inertially move toward one side of the runway. And this kind of use habits because long-term force is applied to a specific area of the runway, it is likely to cause uneven wear of the runway, and may eventually reduce the life of the treadmill.

Therefore, how to improve the treadmill to improve the safety of the user and increase the life of the treadmill in order to overcome the above-mentioned shortcomings has become one of the important issues to be solved in this business.

First, refer to FIG. 1, which is a schematic diagram of a treadmill provided by an embodiment of the present invention. An embodiment of the present invention provides a treadmill M, which includes a running track 20, a first signal providing element, a first sensor 51, and a controller 30. The first signal providing element is disposed on the first side 204 of the runway 20. The controller 30 is coupled to the first sensor 51. In detail, the treadmill M further includes a bracket body 10 and an adjustment panel 103 mounted on the bracket body 10. The controller 30 is disposed in the control panel 103. The control panel 103 provides the user with related information such as running speed, time, and warnings, and can directly adjust the runway through the above information. The bracket body 10 is provided at A front end 201 of the runway 20 has two opposite sides, and a first support rod 101 and a second support rod 102 extending upward respectively. The first sensor 51 is disposed on the first support rod 101. It is worth mentioning that the position set by the first sensor 51 can completely capture the first light pattern provided by the first signal providing element. The runway 20 includes a track 202 and a base 203 supporting the track 202.

The first signal providing element is used to provide a light beam to the first sensor 51. For example, the first signal providing element may be a light reflecting element having a high reflection coefficient or a light emitting element.

In detail, the first signal providing element may be a light emitting element, such as an element that can actively provide a light beam such as infrared light, laser light, or LED. Alternatively, the first signal providing element may be a reflective element having a high reflection coefficient, such as a reflective tape. The first signal providing element may also be formed of glass fluorescent beads. Alternatively, the first signal providing element may be a combination of a reflective tape and glass fluorescent beads. However, the present invention is not limited to this. A person having ordinary knowledge in the technical field may change the material used for the first signal providing element or the type of the light source used by himself according to actual conditions and requirements to complete the present invention. For convenience of explanation, the following signal providing elements mentioned in this embodiment are exemplified by reflective elements, and the first signal providing element is the first reflective element 41.

The first sensor 51 is used for capturing a first image. With reference to FIG. 3, FIG. 3 is a schematic diagram of an embodiment of a first image provided by an embodiment of the present invention. The first image 61 includes a first light pattern 611 provided from the first reflective element 41, and the first light pattern 611 extends from a first starting point S1 in the first image 61.

Referring again to FIG. 1, the first sensor 51 is, for example, a Complementary Metal-Oxide-Semiconductor (CMOS) image sensor or a charge-coupled device (CCD) image sensor. This embodiment is not limited.

It is worth mentioning that, referring to FIG. 3 and FIG. 1B, FIG. 1B is a schematic diagram of a first sensor according to an embodiment of the present invention. The first sensor 51 in the embodiment of the present invention There may also be a first light source 71. The first light source 71 may be disposed on the first sensor 51 to provide a light beam to irradiate the first reflective element 41 to generate a first light pattern 611, thereby improving the clarity of the first light pattern 611 in the first image 61. degree. The first light emitting source 71 is, for example, infrared light or a light emitting diode having a wavelength of 850 nm. It should be understood that the first light emitting source 71 has various changes in different implementation forms, and the embodiment of the present invention is not limited thereto.

Incidentally, in this embodiment, the treadmill M includes only one sensor and one reflective element. However, the present invention is not limited to this. In other embodiments, the treadmill M may also include a plurality of sensors and a plurality of reflective elements. The reflective elements are disposed on the sides of the runway 20. The sensors can completely capture the light pattern provided by a reflective element. For the convenience of description, the following will take the treadmill M as an example including only one sensor and one reflective element.

In this embodiment, the first sensor 51 directly outputs the first image 61 to the controller 30, and the controller 30 performs subsequent calculations based on the first image 61. In other embodiments, the first sensor 51 may further include a first image processor (not shown in FIG. 1). The first image processor receives the first image 61 and calculates an imaging length of the first light pattern 611 according to the first image 61. The first image processor outputs the imaging length of the first light pattern 611 to the controller 30, so that the controller 30 adjusts the runway 20 according to the imaging length of the first light pattern 611.

The controller 30 can directly determine the imaging length of the first light pattern 611 according to the difference in brightness between the first light pattern 611 and the background of the first image 61, and the imaging length of the first light pattern 611 is a first starting point S1. The extended distance is either the distance extended by the first starting point S1 in a predetermined direction P, or the longest distance extended by the first starting point S1 in the predetermined direction P. In this embodiment, the predetermined direction P refers to a direction in which the first light pattern 611 extends from the first starting point S1 to the first end point F1.

Referring back to FIG. 1, the controller 30 controls the driving module to adjust a running speed of the runway 20 according to the imaging length of at least one light pattern (for example, the first light pattern 611). Authentic For example, the controller 30 first receives the first image 61, calculates the imaging length of the first light pattern 611 according to the first image 61, and then adjusts the running speed of the runway 20 correspondingly. The controller 30 is a technique commonly used by a person with ordinary knowledge in the technical field to control the computing system, so it will not be repeated here.

With reference to FIG. 1 and FIG. 3, when the start key (not shown in FIG. 1) of the treadmill M is pressed, the first sensor 51 captures a first image 61 at regular intervals. Since the first reflective element 41 has a high reflection coefficient, the first image 61 shows the first light pattern 611 reflected by the first reflective element 41 to the first sensor 51. When there is no object A (for example, a user) on the treadmill M, the beam pattern reflected by the first reflective element 41 will not be blocked, so the imaging length of the first light pattern 611 is completely represented by the first starting point S1 extends to the first end point F1.

Referring to FIG. 2, FIG. 2 is a schematic diagram of a sensing area of a running track in a treadmill according to an embodiment of the present invention. The running track 20 of the treadmill M is divided into at least a first sensing area SR1 adjacent to the first sensor 51 and a second sensing area SR2 adjacent to the first sensing area SR1. The controller 30 determines that the object A is located in the first sensing area SR1 or the second sensing area SR2 of the runway 20 according to the imaging length of the first light pattern 611, and then adjusts the running speed of the runway 20 correspondingly according to the position of the object A. Actually, in this embodiment, the runway 20 is divided into two areas, the first half area (that is, the first sensing area SR1) and the second half area (that is, the second sensing area SR2), and the rear area is shielded according to the first light pattern 611. The rendered imaging length determines that the object A is located in the area of the runway 20.

Referring to FIGS. 4A and 4B, FIGS. 4A and 4B are schematic diagrams of different masked first images provided by one embodiment of the present invention, respectively. When the object A is located on the track 20 of the treadmill M, the object A will be located between the first sensor 51 and the first reflective element 41 and shield the first light reflected by the first reflective element 41 to the first sensor 51 The pattern 611 makes the first light pattern 611 as shown in FIG. 4A or 4B.

As shown in FIG. 4A, when the imaging length of the first light pattern 611 extending from the first starting point S1 is less than a first preset value TH1, the controller 30 determines that the object A is located in the first sensing area SR1 of the runway 20, The controller 30 accordingly increases the Running speed. Specifically, the controller 30 determines that the speed at which the object A is moving is greater than the running speed provided by the runway 20. Then, the controller 30 directly increases the running speed of the runway 20 through the driving module to match the moving speed of the object A, so that the object A can be maintained at the middle position of the runway 20. In this embodiment, the first preset value TH1 is designed so that when there is no object A on the runway 20, the first light pattern 611 extends from the first starting point S1 to a half of the distance of the first end point F1. Incidentally, the first preset value TH1 provided in this embodiment is merely an example, and is not intended to limit the present invention. Those with ordinary knowledge in the technical field may design the value of the first preset value TH1 according to actual conditions and requirements.

As shown in FIG. 4B, when the imaging length of the first light pattern 611 extending from the first starting point S1 is greater than the first preset value TH1, the controller 30 determines that the object A is located in the second sensing area SR2 of the runway 20, and borrows This controller 30 reduces the running speed of the runway 20 correspondingly. Specifically, at this time, the controller 30 determines that the moving speed of the object A is less than the running speed provided by the runway 20. Then, the controller 30 directly reduces the running speed of the runway 20 through the driving module to match the speed at which the object A moves.

The following will further introduce the flow of the running track control method of the treadmill M. With reference to FIGS. 2, 4A and 4B, please refer to FIG. 11, which is a flowchart of a runway control method provided by one embodiment of the present invention. The running track control method of FIG. 11 is applicable to the treadmill M of FIG. 1. In step S101, the first sensor 51 captures a first image 61 at regular intervals. The first image 61 includes a first light pattern 611 provided from the first reflective element 41, and the first light pattern 611 extends from a first starting point S1 in the first image 61.

In step S102, the controller 30 receives the first image 61 and calculates an imaging length of the first light pattern 611 according to the first image 61. Alternatively, in other embodiments, the first image processor of the first sensor 51 may receive the first image 61 and calculate the imaging length of the first light pattern 611. Then, the first image processor outputs the calculated imaging length of the first light pattern 611 to the controller 30. In this way, the controller 30 does not need to spend time and hardware resources to calculate the imaging length of the first light pattern 611. Incidentally, for a method of calculating the imaging length of the first light pattern 611, reference may be made to the foregoing, and details are not described herein again.

In step S103, the controller 30 determines whether the imaging length of the first light pattern 611 in the image is greater than the first preset value TH1. If the imaging length of the first light pattern 611 in the first image 61 is not greater than the first preset value TH1, go to step S104. Conversely, if the imaging length of the first light pattern 611 in the first image 61 is greater than the first preset value TH1, the process proceeds to step S105. The controller 30 determines that the object A is located in the first sensing area SR1 or the second sensing area SR2 of the runway 20 according to the imaging length of the first light pattern 611 and adjusts the running speed of the runway 20 accordingly.

In step S104, the controller 30 determines that the object A is located in the first sensing area SR1 of the runway 20, that is, the speed of the object A is greater than the running speed of the runway 20. Then, the controller 30 directly increases the running speed of the runway 20 through the driving module, and returns to step S101. In step S105, the controller 30 determines that the object A is located in the second sensing area SR2 of the runway 20, that is, the speed of the object A is less than the running speed of the runway 20. Then, the controller 30 directly reduces the running speed of the runway 20 correspondingly through the driving module, and returns to step S101.

The above steps S101 to S105 will be repeatedly performed until the stop key of the treadmill M is pressed (not shown in FIGS. 1 and 2), and the operation of the treadmill M is stopped. The start key and the stop key on the treadmill M can be separate keys or the same key.

On the other hand, the treadmill M may further include a second reflective element 42 and a second sensor 52. Referring again to FIG. 2, the second reflective element 42 is disposed on the second side 205 of the runway 20 and corresponds to the first reflective element 41. The second sensor 52 is coupled to the controller 30, and the second sensor 52 is disposed on the second support rod 102 of FIG. 2.

The second reflective element 42 has a high reflection coefficient, and the second reflective element 42 can be made of the same or different material as the first reflective element 41. Those with ordinary knowledge in the technical field can change the second reflective element according to actual conditions and requirements. 42 materials to complete the present invention.

The second sensor 52 is used for capturing a second image. The second image includes The second light pattern provided by the light element 42. The second light pattern extends from a second starting point S2. Similar to the first image 61, the second light pattern in the second image also changes due to the position of the object A.

The controller 30 may determine that the object A is located in the first sensing area SR1 or the second sensing area SR2 of the runway 20 according to at least one of the imaging length of the first light pattern 611 or the imaging length of the second light pattern. The controller 30 adjusts the running speed of the runway 20 correspondingly according to the position of the object A. As for the method in which the controller 30 determines the position of the object A according to the imaging length of the first light pattern 611 or the imaging length of the second light pattern, the method is similar to the flow shown in FIG. 11.

Specifically, when the imaging length of the first light pattern 611 is changed and the second light pattern is not blocked, the controller 30 takes the first image 61 to adjust the running speed of the treadmill M. When the first light pattern 611 is not blocked and the imaging length of the second light pattern is changed, the controller 30 takes a second image to adjust the running speed of the treadmill M. When the imaging length of the first light pattern 611 and the imaging length of the second light pattern are both changed, the controller 30 takes either the first image 61 or the second image to adjust the running speed of the treadmill M.

In addition, the second sensor 52 may further include a second image processor. The second image processor is configured to receive the second image, calculate the imaging length of the second light pattern according to the second image, and then output the imaging length of the second light pattern to the controller 30. The method for calculating the imaging length of the second light pattern by the second image processor is the same as the foregoing method of calculating the imaging length of the first light pattern 611, so it will not be repeated here.

Incidentally, the second sensor 52 in the embodiment of the present invention may further have a second light source for providing a light beam to irradiate the second reflective element 42 to generate a second light pattern. The second sensor 52 may be the same as or different from the aforementioned first sensor 51. The sensor is a technology commonly used by those with ordinary knowledge in the technical field, so it will not be repeated here.

The treadmill M provided by the embodiment of the present invention can directly adjust the rotation speed of the running track 20 by judging the position of the user, thereby the treadmill M can directly give The speed of the user's physical strength. Therefore, the user does not need to press any additional speed-adjusting buttons during the motion state, and even when the user cannot keep up with the running speed of the runway 20, the accident caused by the delay of pressing the emergency switch will not occur. It is worth mentioning that the controller 30 can also output the information of adjusting the runway 20 to the control panel 103, and the control panel 103 reminds the user that the operation of the treadmill M will be adjusted by sound or warning light. In addition, the control panel 103 can simultaneously display the user's exercise information, such as: step frequency, and exercise information.
