Variable speed running device and control method thereof

The present invention relates to a variable speed running device and a control method thereof, and more particularly to a variable speed running device that can be adjusted according to a user's heart rate.

With the improvement of medical knowledge, more and more people have developed the habit of fitness. Among the many fitness equipments, the popularity of treadmills is the highest. The reason is that the treadmills are more powerful than the simple operation. Better fitness equipment for function.

During the user's use of the treadmill, the user's heart rate varies with the intensity and duration of the exercise. However, the running speed of the running belt of the treadmill is set at the factory and is running at a constant speed. Under constant speed operation, it is easy for the user to warm up for a long time in the early stage of exercise, or physical fitness in the late stage of exercise. The consumption is too fast, and during the movement, when the user's heart rate changes, the treadmill cannot actively change the running speed of the treadmill according to the user's current physical condition to provide the user with appropriate training intensity. .

For the heart rate rate, it is customary to attach a heart rhythm patch to the user to detect the heart rate of the user on the treadmill. When the heart rate patch senses that the user's heart rate is too high, A processor lowers the speed of the treadmill; if the heart rate patch senses that the user's heart rate is low, the processor can increase the speed of the treadmill and provide the user with appropriate exercise intensity. However, the heart rhythm patch needs to be directly attached to the user's skin, so that the user's skin has an uncomfortable touch, and during the movement, the sweat from the user is also likely to cause the heart rhythm patch to fall off. The convenience of the user to use the treadmill is reduced.

The above and other objects, features and advantages of the present invention will become more <RTIgt;

The term "force" as used in the present invention refers to a vertical force generated between a first object and a second object. For example, when the first object applies a force to the second object, the force is the first object toward The positive action of the second object or the reaction of the second object toward the first object.

The "two values have a positive correlation" as used in the present invention means that the magnitudes of the two values have a proportional relationship.

Referring to FIG. 1 , which is a preferred embodiment of the variable speed running device of the present invention, the device comprises: a treadmill 1, a pressure sensor 2, a database 3 and a processing unit 4. The pressure sensor 2 is disposed at a contact end of the seat body 11 of the treadmill 1 and the ground. The processing unit 4 is electrically connected to the treadmill 1, the pressure sensor 2 and the data base 3.

The treadmill 1 has a body 11 and a driving unit 12, and the base 11 is provided with a running belt 111 for driving the running belt 111 to rotate. The treadmill 1 of the present invention can be used in various types on the market. The structure of the treadmill for fitness, the detailed structural composition and the principle of actuation can be understood by those having ordinary knowledge in the technical field, and will not be described herein.

The pressure sensor 2 is disposed at a contact end of the seat body 11 of the treadmill 1 and the ground to sense a force between a runner and the treadmill 1 and output a pressure signal. The pressure sensor 2 can be any piezoelectric material of any shape, and in the embodiment, is disposed at four corners of the contact end of the base 11 and the ground to accurately sense the runner and the treadmill 1 The force is applied, and the corresponding pressure signal is output according to the force of different magnitudes.

More specifically, when the runner runs on the treadmill 1, the force between the runner and the treadmill 1 is positively correlated with the force of the contact end of the seat 11 of the treadmill 1 and the ground. Therefore, the pressure sensor 2 is disposed at the contact end of the seat body 11 of the treadmill 1 and the ground, and the induced force can represent the force between the runner and the treadmill 1.

The database 3 is configured to store at least one runner information, the at least one runner information includes a rated heart rate range of the at least one runner, and the at least one runner is at least one when the treadmill 1 is exercising The heart rate of one of the runners and the correspondence between the at least one runner and the treadmill 1 (see below for details).

When exercising, the energy consumption of the runner is positively correlated with the heart rate for the same runner. More research has pointed out that when the runner performs running, the energy consumption is proportional to the force between the runner and the ground, and the force is the vertical force applied by the runner to the ground, or the ground is running toward the ground. The ground reaction force is reversed. It can be seen that the heartbeat rate of the runner is positively correlated with the force between the runner and the ground, that is, if the heartbeat rate of the runner is lower, the force between the runner and the ground is smaller; The higher the heart rate of the runner, the greater the force between the runner and the ground.

In more detail, in order to enable the force between the runner and the treadmill 1 to accurately correspond to the heart rate of the runner, in this embodiment, the manner of establishing the database 3 can be set on the treadmill 1 The pressure sensor 2 at the contact end of the seat body 11 and the ground measures the force between the at least one runner and the treadmill 1 when at least one runner runs on the treadmill 1 and simultaneously utilizes a heart rhythm sensor Recording a heart rate of the at least one runner to establish a relative relationship between a force between the at least one runner and the treadmill 1 and a heartbeat rate of the at least one runner, and storing the relative relationship in the database 3 in advance . When the variable speed running device of the present invention is actually operated, the data of the database 3 can be directly utilized without using an additional heart rhythm sensor.

The rated heart rate range is not limited herein, and may depend on the age or physical condition of the runner. In this embodiment, the maximum number of heart beats per minute of the runner is subtracted from the minimum number of heart beats per minute as a rated heartbeat number, and the number of the rated heartbeats is increased or decreased by the number of the rated heartbeats. A rated heart rate range is defined as a basis for determining the rotational speed adjustment of the running belt 111 of the treadmill 1. For example, the maximum heartbeat number of the runner is 200, the minimum heartbeat number is 68, and 132 after subtraction is the rated heartbeat number. If the 132 is based on the increase and decrease 10 as the rated heart rate range, the rated heart rate range. That is 122 to 142.

The processing unit 4 is electrically connected to the driving unit 12 of the treadmill 1, the pressure sensor 2 and the data base 3. The processing unit 4 can receive the pressure signal of the pressure sensor 2, and output a control according to the pressure signal. The speed signal is transmitted to the driving unit 12, so that the driving unit 12 drives and changes the rotation speed of the running belt 111.

More specifically, when the runner runs on the treadmill 1, the pressure sensor 2 provided at the contact end of the seat 11 of the treadmill 1 and the ground can sense the runner and the treadmill 1 at any time. The force is applied to the processing unit 4, and the processing unit 4 can determine the magnitude of the force according to the pressure signal, and find out from the database 3 the corresponding force corresponding to the running. The heart rate of the person, and at the same time determine the relative relationship between the heart rate and the rated heart rate range.

If the heart rate is in the range of the rated heart rate, indicating that the runner is in a better state of motion, the processing unit 4 can output the speed control signal to the driving unit 12 of the treadmill 1 to maintain the running belt 111. The operating speed; if the heart rate is greater than the rated heart rate range, it means that the current exercise intensity of the runner is too strong, causing an excessive burden on the body, so the processing unit 4 can output the speed control signal to the driving unit of the treadmill 1 12, in order to reduce the running speed of the running belt 111; if the heart rate is less than the rated heart rate range, it means that the current exercise intensity of the runner is insufficient and cannot have better motion efficiency, so the processing unit 4 can output the speed control signal The drive unit 12 of the treadmill 1 is added to increase the running speed of the running belt 111.

Referring to FIG. 2, the variable speed running device control method of the present invention comprises: a database establishing step S1, a force sensing step S2, a data matching step S3, and a speed adjusting step S4.

The database establishing step S1 is to establish the database 3, the database 3 is configured to store at least one runner information, the at least one runner information includes a rated heart rate range of the at least one runner, and the at least one runner The heart rate of the at least one runner and the corresponding relationship between the at least one runner and the treadmill 1 when the treadmill 1 is exercising.

In more detail, in order to enable the force between the runner and the treadmill 1 to accurately correspond to the heart rate of the runner, in this embodiment, the manner of establishing the database 3 can be set on the treadmill 1 The pressure sensor 2 at the contact end of the seat body 11 and the ground measures the force between the at least one runner and the treadmill 1 when at least one runner runs on the treadmill 1 and simultaneously utilizes a heart rhythm sensor Recording a heart rate of the at least one runner to establish a relative relationship between a force between the at least one runner and the treadmill 1 and a heartbeat rate of the at least one runner, and storing the relative relationship in the database 3 in advance .

The force sensing step S2 uses the pressure sensor 2 to sense the force between the runner and the treadmill 1 when the runner moves on the treadmill 1. In this embodiment, the pressure sensor 2 is disposed at a contact end of the seat body 11 of the treadmill 1 and the ground. Since the force between the runner and the treadmill 1 is positively correlated with the force of the contact end of the seat body 11 of the treadmill 1 and the ground, the seat of the treadmill 1 is measured by the pressure sensor 2 The force between the contact end with the ground can be used as the force between the runner and the treadmill 1, and the pressure signal is output to the processing unit 4.

In the data comparison step S3, the processing unit 4 finds the heartbeat rate corresponding to the force in the database 3 according to the force sensed by the pressure sensor 2. When the runner moves on the treadmill 1, the pressure sensor 2 can instantly sense the force applied by the runner to the treadmill 1 and output a relative pressure signal to the processing unit 4, After receiving the pressure signal, the processing unit 4 can determine the force between the runner and the treadmill 1 by using the pressure signal, and find the corresponding heart rate according to the force in the database 3, thereby estimating The current heart rate of the runner who is exercising on the treadmill 1.

In the speed adjustment step S4, the processing unit 4 determines the relationship between the heart rate of the runner who performs the exercise and the rated heart rate range, and outputs the speed control signal to control the running speed of the running belt 111 of the treadmill 1, wherein If the heart rate is within a range of the rated heart rate, the running speed of the running belt 111 of the treadmill 1 is unchanged. If the heart rate is greater than the rated heart rate range, the running speed of the running belt 111 of the treadmill 1 decreases, if the heart rate is less than In the rated heart rate range, the running speed of the running belt 111 of the treadmill 1 increases.

In summary, when the runner runs on the treadmill 1, the pressure sensor 2 provided at the contact end of the seat 11 of the treadmill 1 and the ground can sense the runner and the treadmill 1 at any time. The force is applied to the processing unit 4, and the processing unit 4 can determine the magnitude of the force according to the pressure signal, and find out from the database 3 the corresponding force corresponding to the running. The heart rate of the person, and at the same time determine the relative relationship between the heart rate and the rated heart rate range.

If the heart rate is in the range of the rated heart rate, indicating that the runner is in a better state of motion, the processing unit 4 can output the speed control signal to the driving unit 12 of the treadmill 1 to maintain the running belt 111. The operating speed; if the heart rate is greater than the rated heart rate range, it means that the current exercise intensity of the runner is too strong, causing an excessive burden on the body, so the processing unit 4 can output the speed control signal to the driving unit of the treadmill 1 12, in order to reduce the running speed of the running belt 111; if the heart rate is less than the rated heart rate range, it means that the current exercise intensity of the runner is insufficient and cannot have better motion efficiency, so the processing unit 4 can output the speed control signal The drive unit 12 of the treadmill 1 is added to increase the running speed of the running belt 111.

In addition, when the runner moves on the treadmill 1, the runner does not need to attach a heart rhythm patch or set other rhythm sensors on the body. Through the setting of the database 3, the runner only needs to be normal to the runner. When the machine 1 runs, the corresponding heartbeat rate can be found in the database 3 by the force between the runner and the treadmill 1 to adjust the rotational speed of the running belt 111 of the treadmill 1.
