1 is a network diagram illustrating a virtual riding providing system using a bicycle according to an embodiment of the present invention.

1, the virtual riding providing apparatus 100 communicates with the user terminal 300 and the external server 400, and sets the riding environment of the bicycle 200 according to the received riding basic data, When riding, the user can evaluate the riding ability of the user to evaluate the user's motion state or recommend the riding course to the user.

First, the virtual riding providing apparatus 100 communicates with the user terminal 300 and the external server 400 to receive riding basic data. Here, the riding basic data includes user basic data input by the user, bicycle data selected by the user, physical environment constant data, physical environment basic data, and bicycle standard data.

The user basis data includes weight, sex, height, date of birth, and the like. The user basic data is obtained by evaluating the user's riding ability (i.e., anaerobic ability, aerobic capacity, FTP ability) during riding in a state where the riding environment is set, calculating the occupancy rate corresponding to the user's maximum heart rate, To coincide with the occupancy rate of the user. These contents will be described in more detail below.

The bicycle data selected by the user includes bicycle weight, wheel size, bicycle type, front gear ratio, front gear combination, rear gear ratio, rear gear combination, and the like.

The physical environment constant data includes the wind resistance coefficient, the rolling resistance value, and the like. This physical environment constant data is used to calculate the ground resistance used to control the brake pedal strength of the bicycle 200. [ These contents will be described in more detail below.

The physical environment basic data is data received from an external server (that is, a meteorological office server), and includes the temperature, humidity, wind speed, and wind direction of the current time on the riding course. The physical environment basic data is used to calculate the air resistance used to control the brake pedal strength of the bicycle 200 or to generate the blower intensity signal for controlling the strength of the blower that blows the air to the bicycle 200. These contents will be described in more detail below.

The bike specification data is data representing the actual size of the bicycle 200, including a crank radius, a crank arm length, a flywheel size, a flywheel pulley radius, a brake pedal strength data sheet, and the like.

The virtual riding providing apparatus 100 sets a virtual riding environment according to the riding basic data. At this time, the virtual riding providing apparatus 100 may generate a signal for setting the intensity of the brake pedal of the bicycle 200 and the intensity of the blower for sending the wind to the bicycle 200, and may transmit the signal to the bicycle 200.

First, the virtual riding providing apparatus 100 calculates the air resistance and the ground resistance using the riding basic data, and generates the brake pedal intensity signal according to the total resistance calculated using the air resistance and the ground resistance.

More specifically, the virtual riding providing apparatus 100 calculates the air density using the temperature and wind of the riding course set by the user among the physical environment basic data of the riding basic data, and calculates the wind resistance coefficient and the air density The air resistance coefficient can be calculated, and the air resistance can be calculated according to the air resistance coefficient and the riding speed.

In addition, the virtual riding providing apparatus 100 may calculate the ground resistance using the rolling resistance value of the physical environment constant data of the riding basic data, the inclination of the riding course set by the user, and the vertical drag.

Then, the virtual riding providing apparatus 100 may calculate the resistance using air resistance and ground resistance, and then generate a brake pedal intensity signal according to the resistance and provide it to the bicycle 200. Accordingly, the bicycle 200 can adjust the brake pedal intensity in accordance with the brake pedal intensity signal.

The virtual riding providing apparatus 100 also generates a blower intensity signal in accordance with the wind direction of the riding course set by the user, the internal value with respect to the running direction of the wind speed, and the traveling speed of the user among the physical environment basis data of the riding basic data And provides it to the bicycle 200. Thus, the bicycle 200 can send wind according to the blower intensity signal.

When the user rides on the bicycle 200, the virtual riding providing apparatus 100 calculates the maximum heart rate of the user based on the user basis data of the riding basic data. In one embodiment, the virtual riding providing apparatus 100 can calculate the maximum heart rate of a user using the following equation (1).

[Equation 1]

Maximum heart rate = 208 - (0.7 * age)

The virtual riding providing apparatus 100 determines a reference occupancy rate corresponding to a user's maximum heart rate with reference to a reference occupancy rate table for each heart rate. Here, the reference occupancy rate table for each heart rate is a table in which the reference occupation rate is stored for each user's heart rate. The reason for determining the reference occupancy rate corresponding to the maximum heart rate of the user as described above is that the user calculates the occupancy rate corresponding to the heart rate from the user terminal 300 during the riding by the power according to the resistance of the bicycle 200 during the riding, So as to coach the user's motion state.

In addition, the virtual riding provision apparatus 100 provides respective test programs for measuring an oxygen-free capability, aerobic capability and FTP capability of the user. Based on the results of each test, the user's anoxic capacity, aerobic capacity and FTP capacity are calculated, and then the first comprehensive grade is determined according to the respective levels of anoxic capacity, aerobic capacity and FTP capacity.

First, a process of determining the oxygen-free ability test program and the class of the anaerobic capability provided by the virtual riding providing apparatus 100 will be described. The user adapts to the pedal rotation in the order presented by the program. This test lasts 30 seconds. At the start of the test, the pedal has a specific resistance value. At this time, the specific resistance value differs from user to user and determines the resistance value to be applied to the pedal 240 of the bicycle 200 by using the age, sex, and weight of the user among the basic data of the user.

When the user rotates the pedal hardly for a predetermined time (for example, 30 seconds) under the corresponding resistance, the virtual riding providing apparatus 100 sets the power value measured for a specific time in a specific unit (for example, 5 seconds) , The average power is calculated for each specific unit, and the highest power among the average power per unit is determined as the maximum power. At this time, the average power over a specific time is determined as the maximum power.

Then, the virtual riding providing apparatus 100 determines the fatigue of the muscles in consideration of the time from the start to the maximum power, the difference between the maximum power and the lowest power, and the time from the maximum power to the lowest power. The maximum power, maximum power, and muscle fatigue values thus obtained are assigned respective ratings, and an anaerobic exercise ability level is determined by combining the respective ratings.

Next, a procedure for determining the aerobic ability test program and the aerobic ability level provided by the virtual riding provision apparatus will be described.

In addition to the bicycle, the virtual riding providing apparatus 100 requires a heart rate meter capable of measuring heart rate. The aerobic test program is a process that finds the user's equilibrium heart rate in four steps of power stage. When the user executes the program, the user starts the test after adjusting the pedal rotation according to the guide. This test takes a specific pedal resistance value in Step 1, and the user turns the pedal until it reaches the equilibrium heart rate while maintaining the pedal revolution at 50 rpm under the corresponding resistance.

When the equilibrium heart rate appears within a specific time (for example, five minutes), the virtual riding providing apparatus 100 proceeds to the next step. If the equilibrium heart rate does not appear within a predetermined time, the virtual riding providing apparatus 100 determines that the test has failed and ends. This applies at all stages.

When the equilibrium heart rate is displayed within a predetermined time, the virtual riding providing apparatus 100 determines the pedal resistance value of the next step according to the measured equilibrium heart rate at the next step. That is, the virtual riding providing apparatus 100 determines a resistance value of a multiples (for example, double, triple, quadruple, and the like) of the current pumping resistance value at the present stage as the pumping resistance value of the next step according to the balanced heart rate .

For example, when going from step 1 to step 2, the pedal resistance value of the next step is determined according to the measured equilibrium heart rate. It is branched according to the equilibrium heart rate value to the resistance value of 2 times, 3 times, and 4 times the resistance value of the puddle determined in the 1st step. The process of finding the equilibrium heart rate in step 2 and the process of moving to the next step are the same as in step 1.

When the process goes from step 2 to step 3, the test is performed at the resistance values of 3, 4, and 5 according to the branch determined in step 2. As in the previous steps, the process of finding the equilibrium heart rate and the process of passing through the steps are the same.

If you go from step 3 to step 4, perform the test under 4, 5, and 6-fold resistances along the branch determined in step 2. In the fourth step, the process of finding the equilibrium heart rate is the same, but even if the equilibrium heart rate is not found, the test ends with success. Step 4 is the step of generating more reliable data. The maximum oxygen uptake (VO2max) is calculated using the equilibrium heart rate and resistance values measured at each step of the test. The calculated maximum oxygen uptake is classified according to age and gender.

For example, when the heart rate is 120 bpm in the interval set at 150 power in the aerobic test stage 2, the virtual riding providing apparatus 100 performs the exercise for 30 seconds when the average heart rate during 30 seconds is 120rpm, which is 70% of the maximum heart rate If the average power is 160, then the user's average power 160 is higher than the pre-calculated aerobic test power 150, so the aerobic grade can go up by one.

Lastly, a process of determining the class of aerobic capacity after the virtual riding providing apparatus 100 calculates the FTP capability will be described. The virtual riding providing apparatus 100 changes the rating of the FTP capability if the riding average total power after the riding for a specific time is better than the pre-calculated FTP test result. Then, the virtual riding providing apparatus 100 recalculates the FTP test result calculated in advance using the data recorded in the corresponding riding.

Finally, the process of determining the FTP capability and the process of determining the FTP capability through the FTP test program will be described. When the program is executed, the pedal rotation adaptation process is performed according to the guide. Then riding the riding course provided by the program for 20 minutes with electric power. After 20 minutes of riding, calculate 20 minutes average power and normalize power. The FTP rating is given based on the calculated value.

The virtual riding providing apparatus 100 determines the first overall grade using the anaerobic grade, the aerobic grade, and the FTP grade determined through the above-described process. After selecting the recommended group for the riding course as a basis, we recommend a specific course from the recommended group to the riding course.

At this time, the virtual riding providing apparatus 100 selects a specific detailed course from the course group as a riding course according to the result of comparing the distance class determined through the power class and the aerobic class determined through the anaerobic ability and the FTP ability, Recommended.

In one embodiment, if the power rating determined through the anaerobic capability and the FTP capability is lower than the first comprehensive grade, the virtual riding providing apparatus 100 may recommend a course having a large degree of tilt in the course group as a riding course.

In another embodiment, the virtual riding providing apparatus 100 may recommend a long course of the course group as a riding course if the distance grade determined through the aerobic capacity is lower than the first comprehensive grade.

Then, the virtual riding providing apparatus 100 re-evaluates the user's riding ability when the riding environment is set according to a recommended riding course through the above-mentioned process.

When the user rides on the bicycle 200, the virtual riding providing apparatus 100 calculates the oxygen-free capacity, the aerobic capacity, and the FTP capacity, respectively, of the user, and then, based on the rating of each of the anaerobic capacity, aerobic capacity, The overall grade is determined.

First, a process of determining the class of anaerobic capability after the virtual riding providing apparatus 100 calculates the anaerobic capacity will be described. The virtual riding providing apparatus 100 stores the average power for each section when the average gradient maintains the specific gradient over a specific distance during the riding, and calculates the highest average power among the average average powers of the sections after the end of the riding, Determine the rating based on the comparison of test measurements.

For example, the virtual riding provision apparatus 100 stores an average power of 5 seconds when the average gradient maintains a specific gradient over 5 seconds during the riding, and when the average gradient maintains the specific gradient over 30 seconds, And the highest power of the 5-second interval after the end of the riding and the highest average power of the 30-second interval are compared with the pre-calculated anaerobic test measurement values to determine the rating.

Next, a process of determining the aerobic capacity level after the virtual riding providing apparatus 100 calculates the aerobic capacity will be described. The virtual riding providing apparatus 100 may allow the virtual riding providing apparatus 100 to determine that the average heart rate is within a predetermined heart rate (for example, 50%, 60%, 70%, 80%, or 90% , The class is determined according to the result of comparison with the average power per average heart rate after the end of the riding and the average power according to the previously calculated aerobic test power.

For example, when the heart rate is 120 bpm in the interval set at 150 power in the aerobic test stage 2, the virtual riding providing apparatus 100 performs the exercise for 30 seconds when the average heart rate during 30 seconds is 120rpm, which is 70% of the maximum heart rate If the average power is 160, then the user's average power 160 is higher than the pre-calculated aerobic test power 150, so the aerobic grade can go up by one.

Lastly, a process of determining the class of aerobic capacity after the virtual riding providing apparatus 100 calculates the FTP capability will be described. The virtual riding providing apparatus 100 changes the rating of the FTP capability if the riding average total power after the riding for a specific time is better than the pre-calculated FTP test result. Then, the virtual riding providing apparatus 100 recalculates the FTP test result calculated in advance using the data recorded in the corresponding riding.

Then, the virtual riding providing apparatus 100 recommends a riding course on the basis of the integrated grade of either the first comprehensive grade or the second comprehensive grade according to the difference grade between the first comprehensive grade and the second comprehensive grade can do.

In one embodiment, the virtual riding providing apparatus 100 may recommend a riding course based on the second comprehensive grade if the difference between the first comprehensive grade and the second comprehensive grade is less than a specific grade.

In another embodiment, the virtual riding providing apparatus 100 may recommend a riding course based on the first comprehensive grade if the difference grade between the first comprehensive grade and the second comprehensive grade is greater than or equal to a specific grade.

The virtual riding providing apparatus 100 confirms in real time whether the user is riding in accordance with the user's maximum heart rate and the purpose of the exercise during the riding process of the recommended riding course, and notifies the user of the riding course.

The virtual riding providing apparatus 100 receives a user's purpose of riding before starting the riding. For example, let's choose one of the three options to improve your performance, to improve your performance, to improve your physical fitness, and to lose weight. Depending on the purpose of each exercise, the range in which the heart rate should be maintained during riding changes.

For example, if you want to improve your performance, it is best to exercise while maintaining 70 to 90% of your maximum heart rate. It is good to exercise to maintain heart rate in the range of 60 ~ 80% of the physical enhancement and 50 ~ 70% of the weight loss. Heartbeat is not the ability to control according to a person's will. To adjust your heart rate while riding a bicycle, you must adjust the amount of physical activity by adjusting the speed at which you turn the pedals or by adjusting the resistance on the pedals.

The virtual riding providing apparatus 100 continuously monitors the heart rate of the user, continuously informs the user to exercise in a suitable heartbeat region, and may forcibly lower the resistance if necessary.

The reason for recommending the riding course according to the user's athletic ability rating as described above is to provide a riding course that is easy to maintain the heart rate area in accordance with the purpose of the exercise.

2 is a block diagram for explaining an internal structure of a virtual riding provision apparatus according to an embodiment of the present invention.

2, the virtual riding providing apparatus 100 includes a riding basic data storing unit 110, a display unit 120, a virtual riding environment setting unit 130, a user evaluating unit 140, a course estimating unit 150 And a control unit 160. [0033]

The riding basic data storage unit 110 stores the riding basic data stored in the riding basic data storage unit 110 according to the control of the controller 160. The riding basic data storage unit 110 stores the riding basic data stored in the riding basic data storage unit 110, Server) is stored. Here, the riding basic data includes user basic data input by the user, bicycle data selected by the user, physical environment constant data, physical environment basic data, and bicycle standard data.

The user basis data includes weight, sex, height, date of birth, and the like. The user basic data is obtained by evaluating the user's riding ability (i.e., anaerobic ability, aerobic capacity, FTP ability) during riding in a state where the riding environment is set, calculating the occupancy rate corresponding to the user's maximum heart rate, To coincide with the occupancy rate of the user. These contents will be described in more detail below.

The bicycle data selected by the user includes bicycle weight, wheel size, bicycle type, front gear ratio, front gear combination, rear gear ratio, rear gear combination, and the like.

The physical environment constant data includes the wind resistance coefficient, the rolling resistance value, and the like. This physical environment constant data is used to calculate the ground resistance used to control the brake pedal strength of the bicycle 200. [ These contents will be described in more detail below.

The physical environment basic data is data received in real time from an external server (that is, a meteorological office server), and includes the temperature, humidity, wind speed, wind direction and altitude of the current time on the riding course. The physical environment basic data is used to calculate the air resistance used to control the brake pedal strength of the bicycle 200 or to generate the blower intensity signal for controlling the strength of the blower that blows the air to the bicycle 200. These contents will be described in more detail below.

The bike specification data is data representing the actual size of the bicycle 200, including a crank radius, a crank arm length, a flywheel size, a flywheel pulley radius, a brake pedal strength data sheet, and the like.

The display unit 120 displays and outputs information to be processed by the virtual riding providing apparatus 100. For example, the display unit 120 may output the riding course provided by the virtual riding providing apparatus 100, and may output the speed, the wind direction, the wind speed, and the like upon riding according to the riding course.

The display unit 120 may include at least one of a liquid crystal display, a thin film transistor liquid crystal display, an organic light emitting diode, a flexible display, and a 3D display. One can be included.

In a case where a display unit 120 and a sensor for detecting a touch operation (hereinafter, referred to as 'touch sensor') have a mutual layer structure (hereinafter referred to as 'touch screen' It can also be used as an input device. The touch sensor may have the form of, for example, a touch film, a touch sheet, a touch pad, or the like. For this reason, the display unit 120 can receive riding basic data from the user.

The touch sensor may be configured to convert a change in a pressure applied to a specific portion of the display unit 120 or a capacitance generated in a specific portion of the display unit 120 into an electrical input signal. The touch sensor can be configured to detect not only the position and area to be touched but also the pressure at the time of touch.

If there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and then transmits the corresponding data to the controller 160. Thus, the control unit 160 can know which area of the display unit 120 is touched or the like.

The virtual riding environment setting unit 130 sets a virtual riding environment under the control of the controller 160. [ At this time, the virtual riding environment setting unit 130 may generate a signal for setting the intensity of the brake pedal of the bicycle 200 and the intensity of the blower for blowing the wind to the bicycle 200, and may transmit the signal to the bicycle 200.

First, the virtual riding environment setting unit 130 calculates the air resistance and the ground resistance using the riding basic data under the control of the control unit 160, and calculates the air resistance and ground resistance based on the total resistance calculated using the air resistance and ground resistance, To generate a pedal intensity signal.

More specifically, the virtual riding providing apparatus 100 calculates the air density using the altitude corresponding to the temperature and the course information received in real time from the external server (that is, the weather station server) as shown in [Equation 2] (3), the air resistance coefficient is calculated using the air resistance coefficient and the physical resistance constant data received from the user terminal (), and then the air resistance coefficient and the riding speed are used So that the air resistance can be calculated. The virtual riding providing apparatus 100 may calculate the ground resistance using the inclination of the riding course set by the user, the vertical drag, and the rolling resistance value.

 &Quot; (2) "

Air density = (1.293-0.00426 * temperature) * EXP * (altitude / 7000)

&Quot; (3) "

Air resistance coefficient = air density * wind resistance coefficient

&Quot; (4) "

Air resistance = Speed * Air resistance coefficient

The virtual riding environment setting unit 130 sets the ground resistance using the rolling resistance value of the physical environment constant data of the riding basic data, the inclination of the riding course set by the user, and the vertical drag under the control of the controller 160 Can be calculated.

Then, the virtual riding environment setting unit 130 may generate the resistance using the air resistance and the ground resistance, and then generate the brake pedal intensity signal according to the resistance and provide it to the bicycle 200. Accordingly, the bicycle 200 can adjust the brake pedal intensity in accordance with the brake pedal intensity signal.

In addition, the virtual riding environment setting unit 130 sets the virtual riding environment setting unit 130 to generate a blower intensity signal according to the wind direction of the riding course set by the user, the internal value for the running direction of the wind speed, And provides it to the bicycle 200. Accordingly, the bicycle 200 can send wind according to the blower intensity signal.

The user evaluating unit 140 calculates a user's anoxic capacity, aerobic capacity, and FTP capacity when the user is riding the bicycle 200, and determines a rating of each of an oxygen-free capacity, an aerobic capacity, and an FTP capacity, To the course recommendation unit 150. [

Then, the user evaluating unit 140, when riding by the user in a state in which the riding environment is set according to the riding course recommended by the course estimator 150 through each of the user's anaerobic ability, aerobic ability and FTP ability, Evaluate your riding skills again.

The user evaluation unit 140 determines the occupancy rate corresponding to the heart rate received from the user terminal 300 during riding for each power according to the resistance of the bicycle 200, and generates a heart rate and occupancy rate table for each power.

At this time, the user evaluating unit 140 extracts the occupancy rate corresponding to the heart rate received from the user terminal 300 during the riding in the reference occupation rate table according to the heart rate, stores the corresponding occupancy rate for each power according to the resistance of the bicycle 200, And a share table.

The user evaluator 140 determines a heart rate class and a power class with reference to the heart rate and occupancy rate table for each power depending on the resistance. That is, the user evaluating unit 140 may determine the power rating after extracting the power information from the heart rate and occupancy rate table for each power according to the resistance, determine the heart rate rating after extracting the heart rate information, (150).

The course estimator 150 recommends a course according to the first overall grade determined by the user evaluator 140 under the control of the controller 160. [

At this time, the course estimator 150 calculates the oxygen level determined by the user evaluator 140, the power level determined through the FTP capability determined by the user evaluator 140, and the aerobic ability determined by the user evaluator 140 Depending on the result of comparing each of the distance classes determined with the first comprehensive grade, it is possible to recommend a specific detailed course as a riding course.

In one embodiment, if the power level determined through the anaerobic capability and the FTP capability is lower than the first comprehensive grade, the course weighting unit 150 may recommend a course having a large degree of tilt in the course group as a riding course.

In another embodiment, if the distance grade determined through aerobic capacity is lower than the second overall grade, the course weighting unit 150 may recommend a longer course of the course group as a riding course.

In one embodiment, the course weighting unit 150 may recommend a riding course based on the second general grade if the difference grade between the first and second general grade is below a certain grade.

In another embodiment, the course tracker 150 may recommend a riding course based on the first overall grade if the difference class between the first and second general classes is greater than or equal to a particular grade.

The user coaching unit 160 provides real-time coaching to determine whether the user is performing appropriate exercise while riding a course recommended by the course recommendation unit 150. [

The user coaching unit 160 calculates the maximum heart rate of the user on the basis of the user basis data of the riding basic data when the user rides on the bicycle 200. In addition, the purpose of the exercise is identified through the pre-exercise questionnaire, and the occupancy rate per heart rate area according to the exercise purpose is taken from the occupancy rate reference table for each heart rate area.

Here, the occupancy table for each heart rate area is divided into five areas from 50% to 100% of the maximum heart rate, and the occupancy rate of the heart rate area distribution over the entire exercise time is summarized so that the heart rate area corresponding to the exercise purpose can be maintained according to the exercise purpose Table.
