Embodiment 1

As shown in FIG. 2 and FIG. 5, a control method of a treadmill is disclosed in the embodiment. The treadmill includes a treadmill bracket 401. A distance detecting device 201 is disposed on a position of the treadmill bracket 401 near the control dial 208. The running belt 202 of the treadmill is provided with a first area 403, a second area 404 and a third area 402, wherein the second area 404 is located in the middle of the first area 403 and the third area 402, and the first area 403 is located in the second The area 404 is adjacent to the side of the distance detecting device 201, and the third area 402 is located at the side of the second area 404 away from the distance detecting device 201. The method includes:

S101. Obtain a distance between the user 100 and the distance detecting device 201.

S102. If the distance is within the first area 403 of the running belt, increase the current speed of the treadmill;

If the distance is within the second region 404 of the running belt, maintaining the current speed of the treadmill unchanged;

If the distance is within the third zone 402 of the running belt, the current speed of the treadmill is lowered.

In the present invention, different regions are divided on the running belt according to the distance from the distance detecting device, including a first region close to the distance detecting device, a third region remote from the distance detecting device, and the first region and the first region. The second area between the three areas, so that the distance between the user and the distance detecting device can be detected to determine which area the user is currently in, and the corresponding speed control process is performed according to the current area, for example, at the distance In an area, the current speed of the treadmill is increased, and if the distance is in the second area of the running belt, the current treadmill is maintained. The speed is constant. If the distance is in the third zone of the running belt, the current speed of the treadmill is lowered, so that the treadmill can intelligently adapt to the running speed of the user without requiring the user to manually adjust.

With the solution of the present invention, the treadmill can be adapted to the running speed of the user without requiring manual adjustment by the user. When the user runs faster than the treadmill, the user naturally falls in the first area near the front end of the treadmill. After detecting the distance, the treadmill will increase the speed of the treadmill, so that the user will Moving to the second area, then the user will always be in the middle position; likewise, when the user runs slower than the treadmill, the user's footsteps will fall to the third area near the back end of the treadmill, and the treadmill detects this After the distance, the speed of the treadmill will be lowered, so that the user will move to the second area due to relative motion, so that the user will always be in the middle position (ie, the second area). This not only makes the treadmill more intimate, but also avoids the discomfort that the user suddenly loses or accelerates.

In this embodiment, the adjustment order of the speed can be freely set, for example, the initial running speed is 5 km/h, and if the distance between the user and the distance detecting device is in the first area, the treadmill can increase the speed to 10 km. /h, can also be increased to 8km / h, or 7km / h, or 12km / h, etc., or gradually increase when the height is increased, such as 1km / h per minute, or 1km / h every five minutes, etc. The height adjustment method can be used, and these can be set according to the actual needs of the user.

The treadmill includes a bottom plate 400 to which the treadmill mount 401 is secured, and a running belt 202 disposed on the bottom plate 400.

According to another example, the method further comprises: obtaining a distance between the user and the distance detecting device when the treadmill has not been activated;

If the distance is in the preset activation active area, the treadmill is activated.

This allows the user to stand on the running belt and start the treadmill without operating the treadmill. If the user does not stand in the corresponding effective area, it will not start, which makes it easier for the user to control the treadmill. Control the start of the treadmill.

According to another example, the method further includes controlling the treadmill to stop operating if the distance detecting means does not detect the distance of the user from the distance detecting means within the preset time. This will prevent the treadmill from spinning and wasting power.

According to another of the examples, the distance detecting device comprises an ultrasonic distance measuring device. Ultrasonic detection of distance is more reliable and safe.

According to another example, the step of acquiring the distance between the user and the distance detecting device comprises: acquiring a preliminary distance between the two groups of users and the distance detecting device within a preset time, And averaging the at least two sets of preliminary distances to obtain a distance between the user and the distance detecting device.

In order to get accurate distance information, we use a clever distance test algorithm to get multiple sets of distance information in a very short time, and then average them, so that the distance information obtained will be more accurate, so that we can carry out the corresponding Operation; if we use the running belt with the end of the running belt as the head of the running belt and the other end as the tail, we set a starting point on the treadmill and divide the length from the starting point to the tail into three areas, close to the head area. The running speed of the user exceeds the running speed of the running belt, and the speed of the running belt needs to be increased to adapt to the running speed of the user. The vicinity of the tail area indicates that the running speed of the user is lower than the running speed of the running belt, and the speed of the running belt needs to be adjusted. Low to adapt to the user's running speed, if the user is in the middle area, the running speed of the identifying user is basically synchronized with the running speed of the running belt, and the speed of the running belt is not required to be adjusted. When adjusting the speed of the running belt, the running speed of the running belt can be adjusted according to the distance between the user and the distance detecting device. When the head area is close to the head area, the closer the distance is, the larger the height is. When approaching the tail area, the farther the distance is, the greater the reduction. This allows the treadmill to intelligently adapt to the user's running speed without requiring the user to manually adjust and improve the user experience. In addition, in the running work, if an emergency call is temporarily received and the treadmill is forgotten, the ultrasonic speed control device will automatically stop the treadmill when it detects that no one is running on the belt for a period of time.

When adjusting the speed of the running belt, the running speed of the running belt can be adjusted according to the distance between the user and the distance detecting device. When the head area is close to the head area, the closer the distance is, the larger the height is. When approaching the tail area, the farther the distance is, the greater the reduction. This allows the treadmill to intelligently adapt to the user's running speed without requiring the user to manually adjust and improve the user experience.
