The present invention relates to a treadmill control system. More particularly, two or more treadmills are connected to each other to share data and to mutually control each other as necessary, thereby inducing interest of a user exercising with the treadmill and maintaining the treadmill for a long time. It relates to a system and a control method thereof.

The treadmill is a treadmill, which is called a treadmill, and is widely used in homes and sports centers because it can bring a walking or running effect in a narrow space by using a belt that rotates in an infinite track. Treadmills can walk or run indoors at a moderate temperature even in winter, and the running speed can be arbitrarily adjusted, so the demand is increasing day by day.

In general, when walking or running using a treadmill, it is easy to be a monotonous walking or running exercise, and there is a limit to steadily continuing the exercise using the treadmill. Therefore, the necessity of eliminating the boredom of exercise is increasing in performing a walking or running exercise using a treadmill.

To this end, treadmills are designed to adjust the walking belt speed of the control panel while the user walks or runs to change the speed of walking or running according to taste, but it is cumbersome because the user must operate the control panel while walking or running. In addition, there was a problem that causes a risk of balance unbalanced during exercise.

In addition, the walking or running exercise using the treadmill is performed only by the user alone, not in connection with other users, and thus the necessity of overcoming the limitation that can be exercised alone is increased even though the movement speed or the inclination of the track belt is adjusted. have.

The present invention has been made to solve the above problems, two or more treadmills are connected to each other to share the data of each treadmill by selectively displaying on the screen portion of the treadmill, to exercise the user's boredom It is an object of the present invention to provide a treadmill system and a control method thereof.

In addition, another object of the present invention is to drive a running course of two or more different treadmills at the same time, inducing a bond or interest between users to induce a long-term walking or running exercise using the treadmill.

In addition, the present invention is to control the other treadmill by any one of the two or more treadmills connected to each other, so that even if the user does not directly manipulate the walking or running exercise state, the operation performed by another user or the driving selected by another user By running the course together, it not only motivates you to exercise alone, but also induces competition among walking or running movements, and motivates the user to concentrate on walking or running exercises. Its other purpose is to prevent it.

The present invention is a treadmill system comprising a plurality of treadmills, including a first treadmill and a second treadmill, which are installed to be connected to each other in order to achieve the object described above, wherein the first treadmill is the information of the first treadmill. It provides a treadmill system, characterized in that for selectively transmitting to the second treadmill.

This allows two or more treadmills to mutually share information such as running speed, running distance, calories burned, running slope, travel time, or other information needed for treadmill control, so that the user is not bored and interestingly and steadily. Keep your treadmill running.

Here, the treadmills are provided with a screen unit for displaying the traveling information of the other user and their driving information, respectively. Therefore, the treadmill of any one of the treadmills can display the driving information transmitted from the other treadmill of the treadmills on the screen, it can give the impression such as exercising with the user of the other treadmill. .

At the same time or alternatively, the treadmill of any of the treadmills may be controlled according to the information transmitted from the treadmill of the other of the treadmills. This allows the user to operate his treadmill according to the movement speed or inclination of the track belt controlled by another user even if the user does not directly control the movement speed or inclination of the track belt. Even if the exercise condition is not changed, the user can walk or run according to the exercise condition changed by another user.

The information includes one or more of running speed, running distance, calories burned, running inclination, and running time, and includes control information for controlling another treadmill.

The first treadmill and the second treadmill which are different from each other are preferable in terms of doubling the interest of the exercise while having mutual ties. To this end, the first treadmill and the second treadmill select the same driving course, respectively, so that the same driving course can be mutually traveling. At this time, the driving course includes the inclination information according to the driving distance, and when the user of the treadmill performs a walking or running exercise according to the driving course, the inclination of the track belt rotating in the infinite track is automatically adjusted.

In this way, even if the user does not separately operate the inclination of the track belt, the inclination of the track belt is automatically adjusted according to the traveling distance according to the traveling distance. In this case, the driving course may be a virtual course, or may be any one of 5km, 10km, 20km, 42.195km, etc. of the marathon actually conducted.

In addition, the driving course includes two-dimensional or three-dimensional surrounding landscape information according to the driving distance in addition to the inclination information according to the driving distance, and through the screen unit mounted on each treadmill, within the user and the user's driving distance and a certain range. By displaying the surrounding landscape according to the user's mileage with other users, the user can not only inject virtual reality as if the user is driving in a marathon, but also stimulates the user's desire to exercise using a treadmill, Keep your workouts more interesting.

Here, the treadmills may be treadmills connected by wire or wirelessly in one sports center, or may be treadmills connected by using a communication network such as the Internet in different spaces.

In addition, the information displayed on the screen portion of the treadmill includes not only simply displaying the user's own information and other user's information, but also displaying the extracted information by comparing these information with each other. For example, the driving gap between the user and another user is displayed, or when a driving speed of one of the users is maintained at the current speed, it is overtaken after a predetermined time, or the gap between them is widened to some extent. It calculates and displays what is present.

For example, the screen portion of the first treadmill, the running interval between the user of the first treadmill and the user of the second treadmill, the scheduled time of overtaking between the user of the first treadmill and the user of the second treadmill, Estimated time of arrival of the user of the first treadmill and the user of the second treadmill, calories burned by the user of the first treadmill and the user of the second treadmill, the user of the first treadmill and the user of the second treadmill Heart rate of the user, the running history of the user of the first treadmill and the second treadmill, the current running speed of the user of the first treadmill and the user of the second treadmill, the user of the first treadmill and the second treadmill The current driving position of the user is displayed.

In addition, the extracted information may be displayed in comparison with the driving information with the user other than the user of the second treadmill by the user's selection.

On the other hand, the treadmills, the user further includes a driving drive for driving the track belt in an endless track so as to accelerate when the user is located in front of the track belt, and decelerate when the user is located behind the track belt, Even if you do not operate the control panel unit separately, it is possible to walk or run while accelerating or decelerating the movement speed of the track belt.

The automatic speed control mechanism includes: a front load sensor installed in front of the track belt to measure a load of a user who is exercising on the track belt; A rear load sensor mounted to the rear of the track belt to measure a load of a user exercising on the track belt; And detecting whether the user on the track belt is biased toward the front part or the rear part from the values respectively measured by the front load sensor and the rear load sensor.

Specifically, the front load sensor and the rear load sensor are each formed of one or more load cells. Accordingly, the front load sensor and the rear load sensor formed of a load cell output different voltage values according to the degree of the user's bias toward the front part or the rear part of the track belt, and the output voltage values are respectively converted into an amplifier and an analog-digital converter. Each load value can be measured via.

For example, when the user is biased in the front part of the track belt, the load F1 measured by the front load sensor formed of the load cell becomes larger than the case where the user is located in the center part of the track belt. Since it is biased in the front part of the belt, a control command is issued to accelerate the movement speed of the track belt. Similarly, when the user is biased at the rear of the track belt, the load F2 measured by the rear load sensor formed of the load cell becomes larger than the case where the user is located at the center of the track belt, so that the user Since it is biased in the rear part, a control command is issued to slow down the movement speed of the track belt.

In contrast, the front load sensor and the rear load sensor may be formed of a strain gauge. In this case, four strain gauges may be formed in the front load sensor and the rear load sensor, respectively, and may constitute a complete Wheatstone bridge circuit like the load cell, respectively. Two strain gauges may be formed in the front load sensor and the rear load sensor. The strain gauges for the rear load sensor and the strain gauges for the rear load sensor may be combined to form a Wheatstone bridge circuit.

That is, the front load sensor and the rear load sensor are each formed of one strain gauge at the left, right side of the front part of the track belt, and the left and right side of the rear part, and they form a bridge bridge facing each other to form one bridge voltage. You can also find out where you are by car. Through this, the change in the resistance value of the strain gauge measured in four places can be derived as one bridge voltage difference, so that even if only one relatively expensive amplifier is installed, the user's position can be accurately determined.

When the front load sensor and the rear load sensor are formed of two strain gauges, and the Wheatstone bridge is formed such that the strain gauge for the front load sensor (resistance value R2) and the strain gauge for the rear load sensor (resistance value R1) face each other. If the applied power supply is V, the bridge voltage difference ΔV is expressed by the following equation.

Therefore, when the user is biased toward the front part of the track belt, the R1 value becomes larger, and when the user is biased to the rear part of the track belt, the R2 value becomes larger, so that the sign and absolute value of the value of the bridge voltage difference ΔV are increased. By the size of the user can detect whether the user is biased forward or backward, and to what extent. Through this, by accelerating or decelerating the driving speed of the driving unit for driving the track belt, it is possible to implement an automatic speed control device that is automatically accelerated or decelerated even without user's manipulation. At this time, the resistance values (R1, R2) of the strain gauge for the front load sensor and the strain gauge for the rear load sensor have the same resistance value. Since it is converted, it is preferable in view of ease of control.

When the user runs faster on the track belt, the user is biased toward the front part on the track belt. Since the bridge voltage difference ΔV of the Wheatstone bridge increases and decreases in proportion to the degree of deviation of the user, The amount of acceleration and deceleration of the drive speed of the driver is adjusted in proportion to the bridge voltage difference ΔV of the Wheatstone bridge.

At this time, in order to prevent malfunction due to too high sensitivity in the control of acceleration and deceleration, if the user is not biased forward or rearward by a predetermined amount on the track belt, the movement speed of the track belt is not accelerated or decelerated. Instead, the movement speed of the track belt may be accelerated or decelerated only when the user is biased further toward the front part or the rear part than the predetermined amount on the track belt.

Then, after the user starts walking or running on the track belt, the loads of the front and rear portions of the track belt are measured and averaged, respectively, without accelerating or decelerating the movement speed of the track belt for a predetermined time. It is stored as a voltage difference (ΔVref). This is because the running positions on the track belt are different for each user's inclination, so that the movement position according to the user's inclination can be accurately identified initially, and the moving speed of the track belt can be effectively adjusted according to the user's inclination. For example, if a user has a tendency to move in a slightly biased position in the front part of the track belt, even if the user is somewhat inclined in the front part of the track belt, it is already in the reference bridge voltage difference ΔVref. Since the propensity is taken into account, the speed of movement of the track belt is no longer accelerated unless the user is further biased forward.

In addition, the front load sensor and the rear load sensor are installed in contact with the frame for supporting the deck placed between the upper and lower parts of the track belt so as to support the load of the user in the treadmill. That is, the front load sensor and the rear load sensor may be installed between the frame and the deck, the load of the deck to measure the amount of deformation of the frame to be installed to calculate the load from the deck therefrom It may be.

On the other hand, the present invention is a treadmill system comprising a plurality of treadmills installed to be connected to each other, including a first treadmill and a second treadmill, wherein the treadmills including the first treadmill and the second treadmill are infinite. A track belt rotating in orbit; A driving driver for driving the track belt in an infinite track so as to accelerate when the user is located in front of the track belt and to decelerate when the user is located behind the track belt; And a part or all of the treadmills connected to the first treadmill receive the driving course information selected from the first treadmill and travel the same running course as the first treadmill according to the traveling distance. To provide.

Through this, the user can simply designate another treadmill to which his treadmill is linked, and receive the driving course information selected by the other treadmill to exercise according to the received driving course. At this time, the movement speed of the track belt is automatically adjusted according to the user's intention, and the inclination of the track belt is adjusted according to the driving distance, thereby enabling more exciting and interesting walking or running exercise.

Here, the tread mill including the first tread mill and the second tread mill, the inclined drive unit for adjusting the inclination of the track belt; Further, the treadmills running by the driving course selected by the first treadmill are adjusted inclination of the track belt according to the traveling distance.

In this case, the first treadmill stores a plurality of driving courses in the memory unit, and when any one of the stored driving courses is selected, the first treadmill operates according to the selected driving course, and the second treadmill is operated by the first treadmill. The treadmill receives the information of the selected driving course and operates according to the same driving course.

On the other hand, it is also possible to select a driving course stored in the memory unit of the treadmill, but it is also possible to enjoy a more diverse driving course by selecting the driving course read by the reading unit for reading the medium in which the driving course is stored in advance. Here, the medium may include various forms such as a CD, a DVD, a memory chip, and a USB memory capable of storing driving course information.

The treadmills may have respective screen units, and may simply display the user's own information and other user's information on the screen unit, compare the information with each other, and display extracted information, The surrounding landscape can be displayed together, and the avatars of other users who are similar in distance to the user can be displayed together with the surrounding landscape. Through this, it is possible to run at a faster speed to overtake other users.

At the same time, the treadmills further include a microphone and a speaker, so that the user of a specific treadmill transmits voice information to the treadmill of another user through the microphone and outputs the speaker to the speaker while driving, even if the treadmill is spaced apart from each other. You can talk to each other during a running workout, so you can soothe boredom and encourage each other.

On the other hand, according to another field of the invention, the present invention, the first treadmill that can select any one of the host mode to run in accordance with the driving course selected by itself, and the slave mode running in accordance with the driving course transmitted from another treadmill and CLAIMS What is claimed is: 1. A control method of a treadmill system comprising a plurality of treadmills including a second treadmill, comprising: setting the first treadmill to a host mode and setting the second treadmill to a slave mode; Receiving, by the second treadmill, driving course information selected by the first treadmill and traveling according to the received driving course; It provides a control method of the treadmill system, characterized in that configured to include.

This is because only the treadmill selected as the host mode among the treadmills connected to each other is controlled by itself and the treadmill selected as the slave mode is controlled by the other treadmills, thereby preventing collision between data exchanges. . In addition, any one treadmill travels the same driving course as the driving course selected in the other treadmill, thereby inducing interest of the user using the treadmill and allowing each other to feel a sense of solidarity during exercise. In addition, when the treadmill is selected as the slave mode, the user who is walking or running on the track belt does not change the setting speed of the track belt's moving speed and inclination by directly operating the control panel installed in front of the track belt. Since the movement speed and the inclination of the track belt of the treadmill are controlled, it is possible to concentrate only on walking or running movements, thereby preventing the possibility of disturbing posture balance during the movement.

The method may further include displaying driving information of the first treadmill on the screen of the second treadmill, and displaying driving information of the second treadmill on the screen of the second treadmill. Check the information with each other so you can drive through walking or running.

And displaying a list of other treadmills including the first treadmill selected in the host mode on the second treadmill, so that a user who wants to be controlled by the other treadmill can conveniently tread any one of the treadmills selected in the host mode. Confirm and select.

In addition, measuring the heart rate of the user exercising on a plurality of the treadmill; If the user's heart rate exceeds a predetermined value, controlling the user's heart rate to lower the moving speed or the inclination of the track belt of the treadmill that exceeds the predetermined value; It further comprises preventing excessive exercise of the exerciser's exercise amount as controlled by another treadmill.

And, the plurality of treadmills are provided with a sensing unit for detecting the heart rate of the user exercising in each treadmill, respectively, if the heart rate data detected in each treadmill exceeds a predetermined value, to reduce the drive speed of the track belt, Lower the slope of the control to lower the intensity of the exercise. By doing so, when several users exercise by setting the exercise condition by others and walking or running together, the exercise amount is exceeded by the user's own exercise amount, the user is exhausted or excessive exercise and rather health Harm can be prevented beforehand.

On the other hand, it may be configured to further include a central host control unit for controlling the control unit of the plurality of treadmills collectively, and to control all or a part of the plurality of treadmills to operate in the same manner.

In addition, the driving course selection button 135 may be used not only when selecting the driving course stored in the memory unit 146 of the treadmill, but also when selecting the driving course stored in the DVD 88. . That is, when the DVD 88 is inserted into the medium reading unit 132, the driving course list stored in the DVD 88 is displayed on the screen unit 131, and the driving course list displayed on the screen unit 131 is driven. The course selection button 135 may be selected. In addition, the screen unit 131 may be formed as a touch pad to directly select a driving course by directly touching the corresponding list of the screen unit 131 with a finger.

In addition, when the treadmill 1 is set to the slave mode, in order to select the treadmill to transmit the driving course information for driving the treadmill 1, the treadmill 1, the treadmill 2, 3, 4 connected to the The user list of the treadmill set to the host mode is displayed on the screen unit 131. In this way, the user can more easily select a treadmill to travel on the same driving course as the own treadmill 1.

On the other hand, when the treadmill 1 is set to the slave mode, in order to select the treadmill to transmit the driving course information to drive the treadmill 1, the treadmill 1, the treadmill 2, 3, 4 connected to the The user list of the treadmill set in the slave mode may also be displayed on the screen unit 131. In this case, if the user selects the treadmill of the second user to link with the treadmill driving course of the second user selected as the slave mode, the third user selected by the second user (host mode or another host mode) is selected. The driving course information of the treadmill of the user selected as the user may be transmitted to the treadmills of the user and the second user, respectively, to provide a more convenient control environment for the user by driving the treadmill of the user and the second user.

In addition, not only one type of image information is represented on the screen unit 131, but different types of information may be displayed by dividing into several screens as shown in FIGS. 9 to 13. Then, the driving information such as traveling distance, running time, running speed, calories burned, running inclination and running speed history, heart rate of the other treadmills 2, 3 and 4 connected to the treadmill 1 and the user's own treadmill ( By selectively or simultaneously displaying various information according to the driving of 1) on the screen unit 131, the user may perform a running exercise with a competitive spirit while checking the driving state of another user in real time. Further, the screen unit 131 compares the driving information of the user's own treadmill 1 with the driving information of a selected treadmill among the connected treadmills (for example, the driving interval between two treadmills and the overtaking schedule). Time, estimated time to reach a specific location, heart rate difference, etc.).

The control unit 140 is built in the control panel 130, and the data transmission and reception unit 141 for transmitting and receiving data on any one or more of the other treadmills (2, 3, 4) connected to the driving information and the driving course, The driving course output unit 142 for reading the driving course information from the medium reading unit 132 or the memory unit 146 and the driving information output for processing the read driving course information to be transmitted to the treadmill set in the slave mode.

In particular, as shown in Figs. 14 to 20, the treadmill 1 according to an embodiment of the present invention accelerates when the user is biased forward of the track belt 111 and decelerates when hitting to the rear of the track belt 111. Since the two treadmills are running the same driving course with each other, even if the user does not manipulate the movement speed of the track belt during the walking or running exercise, it is variable according to the user's intention. The walking or running exercise can be performed at an inclination of a predetermined driving course according to the traveling distance at the speed, so that a more exciting and interesting walking or running exercise can be realized.

More specifically, as shown in FIGS. 14 to 20, the automatic speed control mechanism grasps the acceleration and deceleration intention of the user based on the load measured by the load sensor module 190 to determine the speed of the track belt 111. Adjust Specifically, the load sensor module 190 is installed in the front and rear portions of the deck 113, respectively, to measure the load transmitted to the deck 113, the coupling formed protruding laterally from the frame 114 Attached to the bottom of the bending member 192 and the bending member 192 formed of a suitable thickness so that a proper amount of bending deformation is caused by the load from the deck 113 is coupled to the member 191, the coupling member 191 And the strain gauges 193a, 193b, 194a, and 194b formed to be bent and deformed together with the bending member 192 in the elastic section so as to change the resistance thereof. Here, the coupling member 191 and the bending member 192 are firmly fixed to be integrally deformed by a fastening means such as a bolt in a state where the four fastening holes 191a and 192a overlap each other. Further, another through hole 192b of the bending member 192 communicates with a through hole formed in the center of the anti-vibration rubber 115 and is used to fix the anti-vibration rubber 115.

As shown in Fig. 19, the control section includes a pair of strain gauges 194a and 194b having a value of resistance value R2 and a rear portion of the track belt 111 so as to measure the load of the front portion of the track belt 111 as shown in FIG. A pair of strain gages 193a and 193b having a value of resistance R1 facing each other to measure the load, the front strain gauges 194a and 194b and the rear strain gages 193a and 194b of the Wheatstone bridge. An amplifier for amplifying the bridge voltage difference ΔV between the first contact 181 and the second contact 182 between 193b) and an analog-to-digital converter for converting the amplified signal into a digital signal. . Then, the digital signal converted through the analog-to-digital converter is transmitted to the control unit, and the moving speed of the track belt 111 is adjusted by adjusting the driving speed of the driving unit 112a based on this. That is, the automatic speed control mechanism of the track belt 111 is implemented by the load sensor module 190 and the control unit.

The control unit may further include a bridge voltage difference ΔV between the first contact 181 and the second contact 182 between the front strain gauges 194a and 194b and the rear strain gauges 193a and 193b. When larger, the track belt 111 is driven to rotate itself even if the user does not press a separate start button. The bridge voltage difference ΔV forms a waveform of a constant period while walking or running on the track belt 111, but the bridge voltage difference ΔV does not form a waveform of a constant period for a predetermined time. Or close to zero, the user is considered not to be on the track belt 111, and the movement of the track belt 111 is stopped.

Through this, the user does not input separately to drive the track belt 111, the track belt 111 starts to move automatically even if it just climbs on the track belt 111, the user separately track belt 111 Even if the user only comes down from the track belt 111 without a separate operation to stop the movement of the track belt 111, the movement of the track belt 111 stops by itself, thereby greatly increasing the user's convenience.

At this time, when the power supply (POWER SUPPLY) is applied to the Wheatstone bridge, the bridge between the first contact 181 and the second contact 182 between the front strain gauge 194a and the rear strain gauge 193a. The voltage difference ΔV is expressed by Equation 1 described above.

Therefore, when the user is biased toward the front part or the rear part of the track belt 111, the strain gauge provided on the biased side becomes larger than the resistance value of the strain gauge on the unbiased side, so that the sign of ΔV is Depends on the direction of eccentricity. In addition, the greater the bias toward either side, the larger the resistance value of the strain gauge on the biased side, while the resistance value of the non-biased strain gauge becomes relatively smaller, so that the absolute value of ΔV in proportion to the bias Will change. Accordingly, the moving speed of the track belt 111 is accelerated or decelerated according to the sign of ΔV and the magnitude of the absolute value, and the track belt 111 according to the acceleration / deceleration input by the user even if the magnitude of the absolute value of ΔV is the same. The acceleration and deceleration of the movement are controlled differently.

At this time, in view of the walking or running movement pattern of the user, since the bridge voltage difference ΔV forms a waveform of a constant period, the bridge voltage difference Δ in determining the increase or decrease of the bridge voltage difference ΔV. It is preferable to adjust the moving speed of the track belt 111 based on the root mean square (RMS) value or the peak value of V).

At this time, referring to Figure 16 looks at the control method of the automatic speed control mechanism as follows. When the position on the track belt 111 of the user deviates to some extent, the acceleration / deceleration is converted into the bridge voltage difference ΔV and input to the controller as the initial set value ΔVset.

When the user ascends the track belt 111 and presses the exercise start button and starts a walking or running exercise, the track belt 111 is not automatically accelerated or decelerated for a predetermined time of about 15 seconds after the start of the exercise. The load is measured by the load sensor module 190 at the front part and the rear part of the belt 111, respectively. Through this, the user who is currently running on the track belt 111 determines which position on the track belt 111 has a tendency to run. Specifically, the average value of the bridge voltage difference DELTA V of the Wheatstone bridge circuit shown in Fig. 19 is obtained for about 15 seconds after the start of the exercise, and the average value is stored as the acceleration / deceleration reference bridge voltage difference DELTA Vref.

Then, when the user runs faster and the user's body is biased toward the front part of the track belt 111, the bending member 192 installed in front of the user is more than the bending member 192 installed in the rear. Since bending deformation occurs, the resistance value R2 of the strain gauges 194a and 194b in the front portion becomes large, whereas the bending member 192 provided in the rear hardly causes bending deformation, so that the resistance of the rear strain gauges 193a and 193b occurs. The value R1 hardly changes. Therefore, according to equation (1), ΔV becomes a negative sign, and as the user moves to the front part of the track belt 111, its absolute value increases. At this time, when the absolute value of (ΔV-ΔVref) exceeds the absolute value of the initial setting value (ΔVset), the degree to which the user is biased toward the front part is set through the initial setting value (ΔVset). Since it is biased, the command for accelerating the moving speed of the track belt 111 in proportion to the magnitude of the absolute value of (ΔV-ΔVref) is transmitted to the control unit, so that the user's track belt 111 can be operated even if there is no user's separate operation. The position of the track belt 111 is accelerated by detecting the position on the track belt 111.

Similarly, when the user's body is inclined to the rear part of the track belt 111 as the running speed is slowed while the user is tired during the exercise, the bending member 192 installed in front of the bending member 192 installed at the rear of the user Since more bending deformation occurs, the resistance value R1 of the strain gauges 193a and 193b in the rear portion increases, whereas the bending member 192 provided in the front hardly causes bending deformation, and thus the front strain gauge 194a. , Resistance value R1 of 194b) hardly changes. Accordingly, ΔV becomes (+) according to Equation 1, and the absolute value of the ΔV becomes larger as the user moves to the rear portion of the track belt 111. At this time, when the absolute value of (ΔV-ΔVref) exceeds the absolute value of the initial setting value (ΔVset), the degree to which the user is biased to the rear part is set by the initial setting value (ΔVset). Since it is biased, the command to reduce the moving speed of the track belt 111 in proportion to the magnitude of the absolute value of (ΔV-ΔVref) is transmitted to the control unit, so that the user's track belt 111 can be operated even if there is no user's separate operation. Detects the position on the track belt 111 to slow down the movement speed of the track belt 111.

At this time, whether to accelerate or decelerate the movement speed of the track belt 111 depends on the sign of (ΔV−ΔVref). The adjustment of the movement speed of the track belt is continued until the user's running movement ends.

That is, as shown in FIG. 4, the controller 140 determines the position of the user on the track belt 111 from the bridge voltage difference ΔV between the strain gauges 193a, 193b, 194a, and 194b. Not only adjusts the moving speed of the track belt 111 according to the position, but also controls the inclination according to the driving distance according to the driving course information transmitted from the medium 88 or other treadmill, and detects the traveling distance of the track belt 111 2D or 3D surrounding landscape according to the traveling distance of the selected driving course is displayed on the screen unit 131, and selectively displays driving information received from other treadmills 2, 3, and 4 or displays the received driving information.
