Description

Treadmill with walking information analysis function and analysis method thereof {Walking information analyzing treadmill and analyzing method thererof}

The present invention relates to a treadmill with a walking information analysis function and a method for analyzing the same. In particular, the magnitude of the input AC current is analyzed to detect a user's step and the state of the walking belt, thereby increasing the reliability of the treadmill and analyzing the motion. The present invention relates to a treadmill equipped with a working information analysis function for improving accuracy and an analysis method thereof.

As social interest in sports increases, the use of treadmills in gyms and homes is increasing. In particular, such a treadmill is widely used as a basic device for aerobic exercise because it can be continued for a long time in a narrow space.

On the other hand, these treadmills are relatively expensive devices equipped with electric devices for driving and various devices for the user interface, and thus the demand for more diverse and accurate motion analysis based on the working information is increasing and needs continuous management. In terms of organizations, the demand for self-verification functions is increasing.

FIG. 1 shows a state of use of a general treadmill. As shown, the treadmill 1 includes a driving unit 2 that is electrically operated and a walking belt 4 that moves at a speed set by the driving unit 2. It is basically provided so that the user 5 can walk or run on the top of the walking belt 4, and the user interface and display 3 for speed adjustment and monitoring of the driving unit 2 are disposed in front of the user. have.

The user interface and the display 3 also include a function for checking the exercise state of the user by arithmetically calculating and displaying the exercise amount information according to the speed of the driving unit 2 based on the speed.

In the case of the general treadmill 1 as described above, the start and the end of the exercise can be set by manipulating the buttons configured in the user interface and the display 3, and the speed of the walking belt 4 can be adjusted by adjusting. In the case of the treadmill 1 that appeared, most of the time, the user is adjusting the constant speed driving state by checking the shock applied to the user's movement in order to maintain the speed set by the user.

However, the conventional treadmill 1 only aims to control the target speed, and there is no consideration of the deterioration of the walking belt 4 which increases the load of the driving unit relatively easily due to use and increases the load of the driving unit. There is a risk of exceeding the capacity, and there is a problem of low reliability because additional information is calculated through measurements that do not take this into account.

In the case of Korean Patent No. 10-0484226, after rectifying the power, the magnitude of the DC voltage is checked, and the current is confirmed while converting the rectified DC voltage into an AC voltage for driving the motor through an inverter, and the actual rotation speed of the motor. It is configured to collect the output of the encoder for confirmation and to compensate the difference between the input and the actual movement speed by a feedback method. That is, by continuously performing the process of varying the torque by varying the current value for the motor during the exercise can be expected to maintain the constant speed even if the user's weight or exercise state changes.

However, since this method is designed to maintain a fixed encoder rotation speed by varying the current value based on the encoder output, when the belt is aging according to the use, if the current consumes a lot, the current exceeding the limit capacity of the motor depends on the user's movement. If necessary, the motor can be overloaded, which can lead to mechanical damage or power problems. In other words, although complex sensing means are used, electrical stability, which is the basis of the reliability of the treadmill, cannot be guaranteed.

This is the same problem in the case of Korean Patent No. 10-0373599. The registered patent controls the walking belt movement speed by encoder feedback and additionally identifies the user's position by dividing the walking belt region into a plurality. After that, the user's location information is used as the information on the exercise state to automatically adjust the speed. As described above, if the user wants to drive the motor at a desired speed due to the weight of the user or the aging of the belt due to use, the limit capacity of the motor may be exceeded, thereby ensuring basic electrical stability of the treadmill. none.

In addition, the Korean Patent Publication No. 10-2004-0081995 discloses a technique for automatically measuring the weight through a treadmill, which simply increases the torque applied to the motor in milliseconds when the user stands on the walking belt. Check the torque at the time when the motor is driven as a value for measuring the weight of the user, and then check the weight through the correlation table for the prepared weight and torque to measure the weight of the user. Therefore, it is difficult to consider the contact friction force of the working belt, so that the reliability of the measurement result is low. In addition, in this case, since there is no consideration of the aging of the walking belt according to the use, the friction force and the torque increase which are greatly increased according to the aging of the walking belt are not considered. .

As a result, as described above, in order to operate the treadmill reliably, the consideration of the degree of deterioration of the working belt and the increase of the driving motor load due to use is not considered at all.

On the other hand, in order to grasp the user's exercise state to provide the exercise effect more accurately, it is necessary to analyze not only the speed but also the user's step to analyze the exercise effect that fits more personal characteristics. A plurality of sensors are attached to the bottom of the belt to determine the working state based on the impact of the user's position or movement.

In the case of Korean Registered Room No. 20-0360363, a plurality of infrared sensors and shock detection sensors are arranged to check the user's walking and movement according to the detected user's motion, but the cost increases for additional sensor placement. Of course, due to the characteristics of the treadmill that continuously generates more than a few tens of kilograms of impact, sensor failures are frequent and low in effectiveness.

In addition, in order to analyze the walking state of the user, it is possible to accurately analyze only by considering the basic load according to the state of the walking belt, but as described above, in the related art, the operation or measurement of the treadmill is considered in consideration of the state of the walking belt. Correction has not been made.

The state of such walking belts is serious until the skilled person can physically check the tension of the belt or add a complex tension measuring structure. After the occurrence of the belt to replace or repair the management of the treadmill is a big situation. In particular, the fact that the user should be able to check the aging degree of the walking belt during exercise due to the characteristics of the treadmill that starts driving while the user is on the walking belt makes it more difficult to implement the function of measuring the aging belt.

On the other hand, as various smart terminals are becoming more common, applications that support exercise schedules or exercise amount analysis are emerging, so if the treadmill used as a basic exercise device of aerobic exercise can provide exercise information through more accurate walking information analysis, Utilization will increase, but treadmills that reliably perform accurate walking analysis have not emerged.

Korean Patent Registration No. 10-0484226 Korean Patent Registration No. 10-0373599 Korean Patent Publication No. 10-2004-0081995 Korean Registration Room No. 20-0360363

BRIEF DESCRIPTION OF THE DRAWINGS The above and other objects, features and advantages of the invention will become more apparent from the following detailed description of the present invention when taken in conjunction with the accompanying drawings.

2 is a block diagram showing an example of the configuration of the treadmill 100 according to an embodiment of the present invention, as shown in the power supply unit 10 to which the external AC power is applied, and through the power supply of the power supply unit 10 A driving unit 30 including a driving driver generating a set level of electric power, a motor to which the output of the driving driver is connected, and a working belt rotating by the motor, and driving of the power supply unit 10 and the driving unit 30. The current sensor unit 20 disposed between the drivers to measure the current consumption, the user interface unit 60 for receiving the set speed and input the weight information, and the drive unit 30 through the current sensor unit 20 Receiving the current value consumed by the) and the aging of the walking belt using the exercise speed setting value and weight information and the pre-configured table information obtained from the user through the user interface 60 Work analysis unit 50 for grasping and analyzing walking information such as steps and stride lengths, an input speed of the user interface unit 60 and a result of the walking analysis unit, and thus the exercise speed, distance, steps, stride length, and calories burned. And a control unit 40 for performing an exercise analysis including at least one of the following, and determining whether to alarm on a walking belt state, and a display unit 70 for displaying a result provided by the control unit 40 to a user. . If necessary, a communication unit 80 may be further provided to communicate with an external terminal. In this case, the controller 40 may identify a paired external terminal and transmit the result of the exercise analysis through the communication unit 80. .

The controller 40 controls the drive unit 30 based on an exercise condition (speed, etc.) set through the user interface 60 similarly to the controller 40 applied to a general treadmill, Based on the driving state in accordance with the movement distance, the amount of calories consumed by the exercise, the general analysis results for the exercise time can be calculated and provided through the display 70. However, the control unit 40 according to the embodiment of the present invention further receives the user's weight information through the user interface unit 60 in addition to the general function and provides it to the working analysis unit 50. A more detailed working analysis result may be received through the working analysis unit 50, and the individual exercise analysis result may be calculated based on this, and a self-checking result of confirming the aging information of the walking belt may be provided. In addition, it is possible to prevent an excessive increase in the load of the driving unit due to the aging of the walking belt and to accurately analyze the working state of the user in consideration of the degree of aging of the walking belt.

For example, even if you walked the same distance at the same speed, if the taller person walked with a wider step and a smaller number of steps, the heat consumed less than the shorter person walked with a narrower step. do. Therefore, if accurate information about the number of steps and stride length can be obtained, more accurate analysis of individual exercise results is possible. In addition, when the working belt becomes aging and the frictional force increases, the driving current consumption increases to provide the same movement speed. Therefore, unnecessary power consumption increases and operating cost increases, and the driving driver or the motor is damaged by the increase of the driving load. This may be checked to inform the user of the need to check the working belt. In addition, the walking analysis criteria may be changed in consideration of the change in the measured value due to the increase in frictional force due to the aging of the walking belt, thereby making it possible to accurately determine the walking and stride length.

To this end, the working analyzer 50 may include a walking belt current value table and a step-by-step step detection reference current value table for the weight and exercise speed measured based on the new walking belt internally in the weight table 53. have. The walking belt current value table is for determining the aging of the walking belt, and the step-by-weight step detection reference current value table is for step determination, and thus, only a table necessary for using one of these functions may be provided.

The walking analyzer 50 is inputted through the user interface to determine the aging belt and the current information corresponding to the weight table 53 according to the set exercise speed and the user weight information transmitted through the control unit 40 It may be provided with an aging determination unit 52 to determine the degree of aging of the walking belt by obtaining the, the current value measured by the current sensor unit 20 and comparing them. The aging determination unit 52 may provide the control unit 40 with alarm information or flag information for notifying when the aging belt is older than or equal to a preset reference, and may simply provide the aging level to the control unit 40. have. Meanwhile, the aging information of the walking belt may be divided into predetermined sections or averaged to a specific value and used to change a reference value when analyzing an exercise or determining a step to be performed later.

The walking analysis unit 50 is the step detection reference current corresponding to the weight table 53 according to the user weight information input through the user interface and transmitted through the control unit 40 to determine the user's step To obtain the step detection reference current value (stepping current for determining the start of the step, stepping current for determining the end of the step) of the value table, and to obtain the measured current value measured through the current sensor unit 20 By comparing these steps, one step can be measured by checking the start and end of the steps, and a step determination unit that measures the stride length by counting these steps and obtaining a period between steps by referring to the number of steps and the speed of exercise ( 51).

In addition, the step determination unit 51 of the walking analyzer 50 may adjust the step detection reference current value with reference to the degree of aging of the walking belt obtained from the aging determiner 52. For example, if the aging of the walking belt is progressing and more current of about 0.5A is measured for the corresponding weight on average compared to the new walking belt, the standard can be corrected by raising the step detection reference current by about 0.5A. have.

On the other hand, since the working analysis unit 50 can basically determine the idle (no load) state by measuring the current consumption of the driving unit through the current sensor unit 20, and transmits the information about the idle state to the control unit 40 The controller may also include a function of stopping operation or maintaining a minimum driving state when such idling continues for a predetermined time or more.

More detailed operation of the working analyzer 50 will be described in more detail with reference to FIGS. 5 to 9.

Through the illustrated configuration, the treadmill 100 according to an embodiment of the present invention allows the treadmill to be safely managed through consideration of the aging of the walking belt, and enables personalized exercise analysis through accurate step determination. It can be seen that.

FIG. 3 illustrates an example of the display unit 70 according to the configuration shown in FIG. 2. As shown, the display panel 71 includes a current, average current, It can be seen that additional information 72 is currently displayed, such as the number of steps. Of course, in addition to such direct information, it is natural that the individual calories calculated, the intensity of exercise, and the amount of exercise calculated through this can be provided through various display methods. In addition, through the aging display unit 73 configured in the display panel 71 as shown, when the inspection or replacement of the working belt is required, the user can immediately check it. Of course, it can also provide information about the degree of aging through level meters and numerical information, not just a check indicator.

On the other hand, when the telecommunication machine 80 is configured in the treadmill 100, the control unit 40 communicates with an external terminal while analyzing the results of the exercise (speed, exercise distance, average speed, exercise time, steps, stride length, exercise) Strength, calories burned, etc.) may be delivered to an external terminal. The communication unit 80 may support a variety of wired and wireless communication methods, as well as a simple wired serial communication method, Wifi, Bluetooth, Zigbee, UWB, NFC, IrDA, Wibro, 3G / 4G mobile communication and a variety of local and One or more of the telecommunication schemes may be supported. Of course, for such communication, it is preferable to perform pairing (including mutual registration, authentication, secure connection, etc.) between the external terminal and the treadmill so that the user's information can be safely transmitted.

In particular, when using a terminal capable of application installation and communication, such as smart phones, tablet computers, etc., which have been recently spread rapidly, information on treadmills may be collected through the installed applications to manage exercise schedules. It can automatically instruct you according to the exercise schedule you need or deliver necessary information.

For example, when a user who has a smartphone paired with Bluetooth and has a workout management application installed therein that supports the treadmill's communication method approaches the treadmill, the treadmill automatically identifies the Bluetooth of the smartphone and Interworking will be performed. After that, when the user climbs on the treadmill and presses the start button of the treadmill, the treadmill receives the user's weight and today's exercise schedule information from the corresponding exercise management application through the Bluetooth of the smart phone, and automatically sets the required exercise time and exercise speed. The operation can then be performed. After the workout is completed, the treadmill can transmit the amount of exercise, the number of steps measured, the stride length, and the result of the exercise analysis to the application through the Bluetooth.

Figure 4 shows an example of the external terminal described above, in the case shown is a screen that can be checked for the walking belt and basic exercise information display and speed control of the treadmill. Of course, this function may be performed as an independent application as shown in the configuration, or may be applied in the form of an add-on to a commercial exercise scheduler or a general platform.

FIG. 5 is a graph illustrating an operating state of a current sensor unit for analyzing a working analyzer, and the current sensor unit of the present invention may be configured to be directly connected to an external power source connected to a driving driver of a driving unit to measure a consumption current There is a direct connection to the 220V 60Hz signal as shown can detect the current change at a speed of 1KHz. The current sensor part that can measure current accurately with sampling rate of 1KHz and various resolutions from 8bit to 12bit can be implemented at a relatively low cost because there is a wide variety of general purpose, even at 1KHz speed as shown Since the period is only about 1ms, a 60Hz signal can measure about 16 times in one period, providing sufficient precision, and it is relatively easy to reduce the measurement period if necessary.

Recently, the performance of the microcontroller used as a general controller has been improved. Most microcontrollers have an internal analog-to-digital converter with a cycle of 1us or less and a resolution of 10bit or more. In addition, since a current sensing circuit consisting of a simple passive element can be configured and measured by an embedded analog-to-digital converter, it may be possible to configure a sensing unit, a working analysis unit, and a controller having high safety and high resistance to shock at low cost.

Figure 6 shows an example of the working belt current value table for the weight and exercise speed measured on the basis of the new working belt configured in the weight table of the walking analyzer. As shown in the figure, the current value measured when using a new walking belt for each weight and speed can be checked. Since the current value increases as the working belt ages, it is possible to accurately predict the aging degree of the working belt through these tables and actual measurements.

7 is a flowchart illustrating a measuring process of a aging belt according to an exemplary embodiment of the present invention. When the treadmill is driven and enters a normal state, the measuring process of the aging belt may be performed once or periodically. First, as shown, first check the exercise state information (speed, other variable information (tilt, variable speed scheduling, etc.)) obtained through the user interface (the input obtained through the external terminal can also be regarded as obtained through the user interface). Then, check the weight information of the input user.

After the state information and the weight information are obtained, the current consumption unit measures the current consumption of the driving unit currently in motion, and then the working belt for the measured weight and exercise speed based on the new working belt corresponding to the state information and the weight information. The current value of the current value table is compared with the measured current consumption amount (of course, the current value of the working belt current value table may be obtained first and then the current consumption value may be measured).

If it is within the preset range as a result of the comparison, it is determined that the state is good, and if the range is exceeded, information for requesting replacement or inspection of the working belt is transmitted to the controller. Of course, the comparison results can be utilized separately.

8 is a conceptual diagram illustrating a step determination process according to an exemplary embodiment of the present invention, and a graph schematically illustrates a measurement result of a current sensor unit according to a user's step.

As shown in the figure, the output of the current sensor unit outputs the current value of A1 for the basic load (the load between the steps of walking or running), and the increased current value for a certain period of time when the user steps on the walking belt. do. Since the graph shown is a schematic diagram, the output under the basic load is constant and the output in the case of a step appears to increase and decrease constantly, but in practice, it varies according to the frictional force of each section of the belt, the characteristics of the driving unit, and the movement of the user. The noise source is included.

Therefore, in order to grasp the exact user's step from the mixed output of various noise sources, the step current A2 close to the high current output obtained by the general user's step is set as the start of the step, and the high current output decreases below a certain level. By setting a predetermined point to the stepping current A3, noise is detected by using a method of determining the step Ts as one step until the stepping current A3 is measured and then the stepping current A3 is measured. To filter.

Since the stepping current A2 and the stepping end current A3 are determined according to the user's weight, a step-by-step stepping reference current value table matching the stepping current A2 and the stepping end current A3 is prepared for each weight. Based on this, the output can be determined by monitoring the output of the current sensor unit. After obtaining the period Tw between the steps and calculating based on the current movement speed, the stride length of the corresponding step can be obtained.

On the other hand, in the case of such a step determination, a reference for speed may be added to the step detection reference current value table for each weight, but since the output under basic load is being measured, the step current (A2) and the step end current ( When measuring by adding A3), it may be possible to set the weight alone.

Of course, since the current value for the weight increases with the aging of the walking belt, more accurate steps can be measured by reflecting the result value of the walking belt aging determination in the step detection reference current value.

FIG. 9 is a flowchart illustrating a step measurement process according to an exemplary embodiment of the present invention, wherein the step measurement may be continuously performed during an exercise, and is preferably performed after determining the working belt aging described in FIG. 7 to reflect corresponding aging information. It is good to carry out.

First, when the running speed of the treadmill is in a steady state, the step measurement is performed, and the exercise state information obtained through the user interface (speed, other variable information (tilt, variable speed scheduling, etc.)) is checked, and the input of the user By checking the weight information, a step of detecting the reference current value is obtained from the step-by-weight step reference current value table.

Now, while measuring the current consumption of the driving unit currently in motion through the current sensor unit to check whether the measured current (A3 in FIG. 8) is detected, if it is detected, the step count is increased by 1 and the step count is prohibited.

Thereafter, while measuring the current consumption of the driving unit currently in motion through the current sensor unit, it checks whether the measured amount of step current (A2 in FIG. 8) is detected and releases the prohibition of step count increase.

By repeating the procedure of performing the two comparison processes while measuring the current consumption during the exercise, it is possible to clearly determine the number of steps during the exercise.

Of course, in the process of increasing the step count by one, the stride length can be obtained by a time difference from the previous step, and the stride length can be accumulated to obtain average stride information.

On the other hand, the walking analysis unit determines that the idle current during the walking belt aging measurement or the step measurement process described above, or separately, if the current consumption of the driving unit is less than the predetermined value, the control unit stops the running of the treadmill or minimum driving Intelligent control to maintain state may also be possible.

In the above described and illustrated with respect to preferred embodiments according to the present invention. However, the present invention is not limited to the above-described embodiments, and various changes and modifications may be made by those skilled in the art without departing from the scope of the present invention. .
