The present invention relates to a treadmill system, and more particularly, to a treadmill system that implements a marathon course as it is, even if the user inputs a desired marathon course without the user adjusting the driving speed or the slope of the track belt.

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, a user uses a treadmill to walk or run while changing walking speed or running speed according to his / her taste in order to alleviate boredom during the walking or running exercise. Since the belt speed adjustment has to be operated every day, it is not only cumbersome but also causes a problem that the balance is disturbed during exercise.

In addition, when the movement speed of the track belt of the treadmill is manipulated by a predetermined program, due to the limitation of exercising according to the uniformly programmed speed, the walking or running speed may not be adjusted according to the user's physical condition or condition. There was a problem that forced or inefficient exercise is forced.

Thus, there have been attempts to find ways to sustain walking or running movements while not intriguing users.

The present invention has been made to solve the above problems, it is to provide a treadmill system that implements the marathon course as it is, even if the user inputs the desired marathon course, the user does not adjust the driving speed or the slope of the track belt. For that purpose.

Further, another object of the present invention is to enable the user to input various courses according to the user's taste, and to prevent the tedious repetition of only uniform courses.

In addition, the present invention, by preventing the acceleration and deceleration too sensitive to the position of the user to provide a stable automatic running speed adjustment environment to the user, to minimize the user's control panel operation for the purpose of the user's convenience do.

Another object of the present invention is to implement a marathon race in which several treadmills are connected to a server, and several users simultaneously play a game.

The present invention, in order to achieve the above object, a track belt rotating in an infinite track, the inclination drive unit for adjusting the inclination of the track belt, the mileage sensing unit for detecting the travel distance of the track belt, and driving It provides a treadmill system characterized in that it comprises a control unit for driving the inclined drive unit according to the mileage detected from the mileage sensing unit receiving the course information.

This is because if the user selects a course in advance before starting a running exercise using the treadmill, the treadmill inclination is automatically adjusted according to the mileage even if there is no user's operation, so that the actual marathon course can be practiced more realistically. To make it possible. At this time, the control unit may be formed in the form of a control panel, or may be embedded in any position to be electrically connected in the form of a box.

The memory device may include a memory unit configured to store a plurality of driving courses, and the controller is configured to input information of the driving course to the controller by selecting one of a plurality of driving courses stored in the memory unit. At this time, the driving course includes the slope and image information of the ground according to the well-known courses such as Chuncheon International Marathon, Seoul International Marathon, Seoul Half Marathon and Boston Marathon. In this way, the user can also practice by course while driving the desired course one by one on the treadmill.

The apparatus may further include a media reading unit that reads the media information from a medium in which the driving course is input in advance, so that the driving course information stored in the medium is input to the controller and selectable. Through this, the treadmill manufacturer can extend the driving course that has not been input into the memory, and can walk or run various driving courses.

In addition, the driving course may be configured to select arbitrary driving course information by using a geographic information system (GIS) in which the altitude is displayed, and input information including the inclination and the like to the controller.

The treadmill system may further include a connection terminal connected to the Internet, and the driving course may be received from a predetermined server through the Internet and input to the controller. Through this, by developing a driving course in a manufacturer or a separate operator to share the course information for a fee or free, users of the treadmill can run a variety of courses.

In general, in consideration of the fact that the degree of reality that is most sensitive to visual effects varies, the virtual reality (VR) receives information of a driving course, and according to the driving distance detected from the driving distance sensing unit. It is effective to further include a screen unit for displaying visual information of the driving course as an image.

In this case, the screen unit may be formed of an LCD (LCD) installed in the front portion of the treadmill, may be installed in the form of a large screen spaced apart from the treadmill a predetermined distance. In addition, the screen unit may be formed of a goggle-type display mechanism connected from the control unit of the treadmill.

It is configured to further include a traveling drive unit for driving the track belt in a caterpillar, so that the track belt is automatically moved even if the user does not push the drive by driving the track belt.

At this time, the driving drive is accelerating and decelerating itself according to the intention of the user. More specifically, when the user is located in front of the track belt, the moving speed of the track belt is accelerated, and the user is located behind the track belt. When shifted, the movement speed of the track belt is decelerated, so that automatic speed adjustment of the track belt is realized. By doing so, the user may not be able to reduce the running speed by a separate switch operation if tired or hard while driving the course, but may run slowly if exhausted even if there is no separate operation, and vice versa.

Therefore, the user simply inputs the driving course using the treadmill at the beginning, and changes the running speed freely without any manipulation, and visually enjoys the surrounding landscape of the input marathon course, and adjusts the slope according to the driving course. You will be able to run the marathon course as it is.

The treadmill system includes a front load sensor installed in front of the track belt to measure the load of the user exercising on the track belt for automatic speed adjustment, and the track belt to measure the load of the user exercising on the track belt. And a rear load sensor installed at the rear of the control unit, wherein the control unit is controlled to accelerate or decelerate the driving unit by calculating a movement position of the user on the track belt based on values measured at the front load sensor and the rear load sensor, respectively. .

The front load sensor and the rear load sensor are each formed of one or more load cells. The load cell is composed of one or more strain gauges whose electrical resistance changes in proportion to the amount of deformation or compression as they are loaded from the outside.The voltage value around the strain gauge changes as the electrical resistance of the strain gauge changes. The sensor calculates the deformation amount of the strain gauge from this, and measures the load applied from the outside in consideration of the physical properties of the material to which the strain gauge is attached. 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, it is possible to derive the change in the resistance value of the strain gauge measured in four places 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 the acceleration and deceleration, the movement speed of the track belt is not accelerated or decelerated when the user is not biased forward or rearward by a predetermined amount. Instead, the movement speed of the track belt may be accelerated or decelerated only when the user is biased further to the front portion or the rear portion than the predetermined amount on the track belt.

In addition, the front load sensor and the rear load sensor are installed on the left and right sides of the track belt, respectively, to what extent the user is eccentrically forward or rearward, even if the user has a tendency to eccentrically move left and right. Whether or not it can be easily detected.

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, the track belt rotating in the infinite track, the inclination drive unit for adjusting the inclination of the track belt, the travel distance sensing unit for detecting the travel distance of the track belt, and receives the information of the driving course, A plurality of treadmills including a control unit for driving the inclined drive unit according to the traveling distance detected by the traveling distance detecting unit; A server in which the plurality of treadmills are connected to each other; A server controller configured to select a plurality of treadmills at the same time and to select one driving course, and to receive the sensed mileage of each of the plurality of treadmills and provide course information according to the mileage; And the treadmills configured to simultaneously select the one driving course, share the driving data with each other, and control the respective inclined driving units according to the course information received from the server control unit.

In this case, each of the treadmill has a screen portion, the course information includes the image information according to the driving distance, the treadmill simultaneously selected the one running course also share the image data of each other and the screen of each treadmill Is displayed in wealth. The server controller shares driving information of the treadmills simultaneously connected to one course. In other words, treadmills allow multiple people to share information about a course while simultaneously running a marathon.

Hereinafter, with reference to the accompanying drawings will be described in more detail the configuration of the treadmill system according to an embodiment of the present invention.

As shown in the figure, the treadmill system 100 according to an embodiment of the present invention is a track unit 110 for the user walking or running movement, and the inclination drive unit 120 for adjusting the inclination of the track unit 110 The controller 110 controls the running speed and the inclination of the track unit 110 and is connected to other servers to communicate with the server 130 and detects the traveling speed and the traveling distance of the track unit 110. The sensor 140 and a load sensor module 190 for measuring the load of the user exercising on the track belt 111 from the front and rear of the track belt 111, respectively.

The track unit 110 includes a track belt 111 moving in an endless track, a drive roller 112 for guiding the movement of the track belt 111 at both ends of the track belt 111, and the track belt 111. Deck 113 formed in a plate shape to support the weight of the user between the upper and lower, and the frame 114 in contact with and support both sides of the deck 113 to support the deck 113, including the user's weight And the anti-vibration rubber 115 installed between the deck 113 and the frame 114 to absorb shocks, and the frame 114 is made of a plastic or metal material that enhances aesthetics so that the frame 114 is not exposed to the outside. From the deco cover 116 formed to cover both sides, the support 117 for supporting the rear portion of the treadmill 100, the drive motor 118 for driving the rotation of the drive roller 112, and the drive motor 118 It is configured to include a transmission belt 118a for transmitting a driving force of the driving roller 112.

Here, the driving motor 119 and the inclined drive unit 120 are installed in the receiving unit 112a located in front of the track unit 110. And, as shown in Figure 2, the track belt 111 is installed so as to be movable in a small track between the drive roller 112, the deck 113 is inserted between the upper and lower surfaces of the track belt 111. . In addition, both sides of the deck 113 supporting the user's weight and exercise shock are supported by a deck support 114a protruding in a 'b' shape from the frame 114. And, between the deck support (114a) and the deck 113, the anti-vibration rubber 115 is installed, to attenuate the impact load of the user to protect the user's knees and the like.

The inclined drive unit 120 includes an elastic member 121 having both ends 121a and 121b rotatably coupled to adjust the inclination of the track unit 110, and a motor 122 that drives the expansion and contraction of the elastic member 121. And a horizontal bar 123 in which one end 121a of the elastic member and the center part 123a are rotatably coupled, a support 134 attached to both ends of the horizontal bar 123, and the front of the treadmill 100. The support roller 125 rotatably attached to the end of the support 124 to support the portion, the center portion is rotatably coupled to the other end 121b of the elastic member 121, both ends protrude near the decor cover 116 It includes a fixing bar 129 is coupled to the formed fastening portion (129a).

As a result, when the stretchable member 122 is extended by the driving of the motor 122, the distance between the fixing bar 129 and the horizontal bar 123 is increased, and the angle between the support 134 and the ground is increased. As the support roller 125 at the end of the support 134 rolls, the inclination of the track portion 110 is greatly adjusted. On the contrary, when the elastic member 122 is reduced by the driving of the motor 122, the distance between the fixing bar 129 and the horizontal bar 123 is closer, and the angle between the support 134 and the ground becomes smaller. As the support roller 125 at the end of the support 134 rolls, the inclination of the track 110 is adjusted to be small. That is, by controlling the rotation direction and the amount of rotation of the motor 122, it is possible to adjust the inclination between the track portion 110 and the ground.

The control panel 130, the control panel 131 is formed so that the appearance is securely mounted inside the memory and the circuit portion, the movement speed of the track belt 111, running distance, calories burned and the marathon selected by the user An LCD 132 displaying image information of the course, a handle 133 protruding from the lower end of the control panel 131 and protruding to be held by the user during exercise or emergency, and the control panel 131 are installed at the waist height of the user. A connection member 134 erected vertically from the track part 110 to be fixed, a horizontal reinforcement 135 connecting between the connection member 134 to reinforce the lateral rigidity of the connection member 134, and various marathon courses And a media accommodation unit 136 formed in the control panel 131 so as to accommodate and read a storage medium such as a CD or a DVD so as to select the control unit.

In this control panel 131, the track belt of the treadmill 100 automatically controls the driving speed of the track belt according to the position of the user, and also according to the driving distance of the track belt to implement the marathon course as it is selected by the user. It automatically adjusts the slope and reads the media input to the media receiving unit 136 so that various marathon courses can be selected, and has a separate network connection to connect to a server such as the Internet to download the marathon courses from the server. A control unit that performs various functions, such as selecting a marathon course stored in a server without downloading it, is seated.

Therefore, as shown in FIG. 13, the control unit receives course information including image information and inclination information from the medium or the server, and the actual travel distance of the track belt 111, thereby driving the track belt 111. FIG. Control the inclination drive motor 122 to implement the inclination according to the marathon course according to the distance, and the LCD 132 or / and the screen 132 'to show the scenery of the course according to the traveling distance of the track belt 111 Can be controlled.

In addition, image information indicating the scenery of the marathon course may be displayed through the LCD 132, but in order to enhance the visual effect of the user, the projection type or the projection type installed on the front of the treadmill system for the user to watch while running It may be displayed through a large screen 132 'such as an LCD. In addition, using glasses-type display control method devised by Nakada Suguru and disclosed in Korean Patent Laid-Open Publication No. 2004-47692, glasses or helmets worn on the user's head to display different screens for each user It can also be used as a type imaging apparatus (not shown). That is, as shown in FIG. 13, the controller 131 detects the travel distance of the track belt 111 and displays landscape information of the marathon course according to the travel distance on the screen 132 'or the wearable image device 132 ". By transmitting a wired or wirelessly, such as by Bluetooth, the visual landscape of the marathon course is displayed on the screen 132 'or the wearable image device 132 ".

The traveling distance sensor 140, as shown in Figure 2, is mounted on the bottom of the deck 113, each time the track belt 111 rotates in an infinite track on the inner surface of the track belt 111 By detecting the displayed sensing strip 111a, the user's traveling distance is sensed. On the other hand, in the embodiment of the present invention has been described with an additional traveling distance sensor 140 as an example, even if there is no separate travel distance sensor, to the drive motor 118 for driving the track belt 111 The controller may be configured to detect an outgoing frequency signal and detect a driving distance and a traveling speed of the user.

The load sensor module 190 is respectively installed in the front and rear portions of the deck 113 to measure the load transmitted to the deck 113, the coupling member 191 protruding laterally from the frame 114 And a bending member 192 coupled to the coupling member 191 to a suitable thickness such that an appropriate amount of bending deformation occurs by the load from the deck 113, and attached to the bottom surface of the bending member 192 in the elastic region. And strain gages 193a, 193b, 194a, and 194b that are bent and deformed together with the bending member 192 to change their resistance.

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. 11, the control unit comprises 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 on 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 controller, and the moving speed of the track belt 111 is adjusted by adjusting the driving speed of the driving unit 112a.

At this time, when the power supply (POWER SUPPLY) is applied to the Wheatstone Bridge, V between the first contact 181 and the second contact 182 between the front strain gauge 194a and the rear strain gauge 193a. The bridge 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. Therefore, the treadmill system according to an embodiment of the present invention is configured to accelerate or decelerate the moving speed of the track belt 111 according to the sign of ΔV and the magnitude of the absolute value.

At this time, the front strain gauges 194a and 194b and the rear strain gauges 193a and 193b are preferably formed to have the same resistance value. However, it may have any resistance value such as 120Ω or 350Ω.

Hereinafter, with reference to Figure 14 will be described in detail the operating principle of the treadmill system 100 for implementing a marathon course according to an embodiment of the present invention configured as described above.

A user who wants to run a predetermined marathon course using the treadmill system 100 inputs driving course information into the control unit 131 of the treadmill system. In this case, the marathon course selected by the user may be one selected from a marathon course previously input to the memory of the control unit 131 of the treadmill system 100. The medium may be placed in the medium receiving unit 136, and the marathon course information may be input / selected by reading from the medium, and the network connection circuit may be connected to the server by wire or wireless to download the marathon information stored in the server. You can choose to take a marathon course by taking it or by reading it. At this time, the driving course information preferably includes data such as the slope of the ground according to the driving distance, the landscape of the two-dimensional or three-dimensional surroundings according to the driving distance, and the wind speed according to the terrain.

 The driving course information does not have to be 42.195 km, and any driving distance such as 5 km, 10 km, and 20 km may be used.

Then, when the user presses the start button and starts the running exercise, the treadmill system 100 implements the driving course selected by the user as it is. That is, the track belt 111 is accelerated at a higher speed when running fast according to the mood or state of the user, and the track belt 111 is decelerated at a slower speed when the user runs slowly. In addition, the mileage sensor 140 detects the mileage of the user in real time, and transmits the detected mileage to the controller 131.

The controller 131 visually displays the scenery of the pre-selected driving course on the LCD 132 or the screen 132 'according to the distance the user has driven by running, so that the user may actually run a marathon course. Feel it. In addition, the controller 131 rotates the driving motor 122 of the inclined drive unit 120 in the forward or reverse direction to adjust the inclination of the preselected driving course according to the distance the user has traveled by running, so as to adjust the selected driving course. Implement the slope as it is.

When the user presses the stop button or completes the selected driving course while driving the course, the driving of the track belt 111 is automatically terminated.

That is, by using the treadmill system 100 according to an embodiment of the present invention, even if the user arbitrarily selects a variety of marathon courses, there is no operation for accelerating or decelerating the movement speed of the track belt or adjusting the inclination after the running starts. By directly feeling the slope and the image landscape according to the driving distance of the selected marathon course, the user feels as if they are actually running the marathon course, and inspires them to walk or run for a long time without being bored.

And, the driving course information input to the treadmill system 100 according to an embodiment of the present invention includes the driving information of the participants of the actual competition, such as the Chuncheon International Marathon, or the driving information of the virtual participants, the CD 132 In addition, the screen 132 ′ may be used to open a simulation game or cyber marathon competition in which a participant other than the user on the treadmill system 100 competes in advance.

On the other hand, the treadmill system 100 according to an embodiment of the present invention, even if there is no user input, the operation principle of automatically adjusting the moving speed of the track belt 111 is as follows. In other words, 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 setting value ΔVset. Then, when the user ascends the track belt 111 and presses the exercise start button and starts a walking or running exercise, the movement speed of the track belt 111 is not automatically accelerated or decelerated for a predetermined time of about 1 minute after the start of the exercise. The load is measured by the load sensor module 190 at the front and rear portions of the track belt 111. Through this, the user who is currently running on the track belt 111 determines the 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. 7 is obtained for about one minute 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 of the front portion becomes large, whereas the bending member 192 provided to 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 undergoes bending deformation, and thus the front strain gauge ( The resistance values R1 of 194a and 194b hardly change. 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.

On the other hand, the configuration of the treadmill system 1000 according to another embodiment of the present invention is shown in FIG. That is, a plurality of first treadmill 100, second treadmill 200, ..., n-th treadmill (300, where n is a natural number) configured as a treadmill 100 according to an embodiment of the present invention described above Are all configured to be connected to the server 99 by wire or wirelessly, the speed of the track belt 111 is automatically adjusted according to the position of the user on the track belt 111, the inclination of the track belt 111 is inclined It is adjusted by the drive unit 120. The driving course selected by the user is displayed on the LCD 132 and / or the screen 132 'according to the user's driving distance.

The first treadmill 100, the second treadmill 200, ..., the n-th treadmill 300 is connected to one server 99 at the same time, the user using the treadmills (100, 200, 300) server 99 You can select a driving course stored at the same time and run a marathon race together. In this case, the server may be a server on the Internet, or may be a server in a sports center having a plurality of treadmills.

Hereinafter, the operation principle of the treadmill system 1000 according to another embodiment of the present invention configured as described above will be described in detail with reference to FIG.

When a user who wants to run together using the treadmills 100, 200, and 300 connects to the server 99 and selects one of the marathon courses among the various marathon courses of the server 99, the server 99 determines the treadmills 100, 200, 300. Transmit the selected course information.

Then, the server 99 notifies the countdown through the LCD 132, the screen 132 'or a separate speaker (not shown), and transmits a start signal to the various treadmills (100, 200, 300). Then, the user of the treadmill (100, 200, 300) starts a walking or running exercise.

Each of the treadmills 100, 200, and 300 detects a user's driving distance using the driving distance sensor 140, and transmits the detected driving distance information to the server 99. At the same time, the server 99 transmits image data, inclination data, wind direction and wind speed data, and travel distance data of another user according to the travel distance of each treadmill 100, 200, 300 to each treadmill 100, 200, 300.

Then, each of the treadmills 100, 200, and 300, based on the data received from the server, the landscape information of the driving course according to the distance traveled by the user walking or running on the LCD 132 or the screen 132 ' Display and instill the feeling of running outdoors in the user, the inclination of the track unit 110 is adjusted by the inclination drive unit 120 according to the inclination of the ground according to the user's driving distance, according to the air volume and wind speed data Fans are installed around the treadmills 100, 200, and 300, and the driving data of the user who is running on another treadmill is displayed on the LCD 132 or the screen 132 'in the form of an avatar to run the running course. It can be realized as if you are actually running a marathon outdoors.

In the running exercise as described above, when the user presses the driving stop button by abstaining in the middle, or completes the initially selected driving course, the statistical data such as the user's driving history and ranking, the time required by each section, and the record of all time are recorded. By displaying on the 132 or the screen 132 ', it is possible to inspire the user's motivation for running.

Although the preferred embodiments of the present invention have been described above by way of example, the scope of the present invention is not limited to these specific embodiments, and may be appropriately changed within the scope described in the claims.

That is, in the embodiment of the present invention has been described by taking only the treadmill as an example, such a system is equally applicable to exercise equipment, such as a bicycle running.

In addition, in identifying the position of the user on the track belt 111, it has been described with an example including the step of identifying which position on the track belt 111 according to the user's inclination, as an example, except that the track belt 111 Can be controlled immediately in accordance with the sign and magnitude of the bridge voltage difference ΔV. And in order to suppress the sensitivity which detects acceleration / deceleration too much, the initial setting which does not perform the acceleration / deceleration adjustment of the track belt 111 when the absolute value of the bridge voltage difference (DELTA) V is smaller than a predetermined value. Although the value? Vset has been illustrated to be set, this may be selectively applied. In this case, since the moving speed of the track belt 111 is accelerated and decelerated in the absence of the initial set values of ΔVref and ΔV, the moving speed of the track belt is adjusted only by the absolute value and the sign of ΔV.

As described above, according to the present invention, if a user inputs a desired marathon course, even if the user does not adjust the driving speed or the inclination of the track belt, the landscape information according to the mileage is displayed on the screen, and the track of the treadmill is displayed. Negative slope is controlled to be equal to the slope of the ground according to the distance traveled by the input marathon course, and the wind direction and wind speed according to the terrain of the marathon race are blown by the fan, so that the user can run the marathon course outdoors even while running indoors. The present invention provides a treadmill system that induces higher utilization by preventing virtual boredom of running exercise and inducing interest by making a virtual reality feel like driving.

In this way, the user can select a variety of courses according to the user's preference to perform a walking or running exercise for each course, so as to avoid boring the running exercise easily by tediously repeating the uniform course only.

In addition, the present invention, by preventing the acceleration and deceleration too sensitive to the position of the user to provide a stable automatic running speed adjustment environment to the user, to minimize the user's control panel operation to facilitate the user's convenience.

On the other hand, the present invention implements that several treadmills are connected to the server, and at the same time several users are running marathon races with each other, so that the user is running indoors using a treadmill, as if playing a networked game with others By inducing such interests, it is possible to motivate the running exercise using the treadmill. In addition, according to the same principle, you can use the treadmill to hold a more vibrant cyber marathon. ㅇ
