Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.

1 is a diagram showing the operation of a bicycle fitting control system according to an embodiment of the present invention.

Referring to Figure 1, the bicycle fitting control system 100 may receive pressure data from the pressure sensor 10. First, the pressure sensor 10 may be provided on the saddle and handle. As an example, a plurality of pressure sensors 10 provided on a bicycle saddle may be placed at saddle positions corresponding to the hip bones, and pressure data applied to each pressure sensor 10 may be measured. Additionally, a plurality of pressure sensors 10 provided on the handle may be disposed at handle locations corresponding to hand bones, and pressure data applied to each pressure sensor 10 may be measured. That is, the pressure sensor 10 can measure pressure data applied to the placed location and transmit each measured pressure data to the bicycle fitting control system.

The bicycle fitting control system 100 may generate bicycle fitting data based on the received pressure data. The bicycle fitting control system 100 can determine the distribution of pressure applied to the saddle and handlebar based on the received pressure data. As an example, the bicycle fitting control system 100 may determine whether the user's hip bone is accurately positioned on the saddle based on pressure data. Additionally, the bicycle fitting control system 100 may determine whether the user's hands are accurately holding the handlebar based on pressure data. The bicycle fitting control system 100 may determine the user's posture using pressure data applied by the user's hip bones to the saddle and pressure data applied by the hands to the handlebars. At this time, the bicycle fitting control system 100 may generate user posture data from the identified user posture and determine whether the user posture has changed based on the generated user posture data. When the bicycle fitting control system 100 determines that a change in the user's posture is necessary because pressure is applied intensively to a specific location, it may request a change in the user's posture from the user terminal 20.

If the user's pain cannot be alleviated even if the user changes his or her posture, the bicycle fitting control system 100 may generate handle fitting data and saddle fitting data based on the body index of the user that has already been registered. The bicycle fitting control system 100 may provide the generated handle fitting data and saddle fitting data to the user terminal 20.

Therefore, the bicycle fitting control system 100 can determine the user's posture using the pressure data applied to the saddle and handlebars and guide the user's hips and palms to be in the correct position based on the determined user's posture. there is. In addition, if pain on the user's buttocks and palms continues even if the user's posture changes, the bicycle fitting control system 100 generates saddle fitting data and handlebar fitting data based on the user's body data to provide real-time information to the user. Optimized bicycle fitting data can be provided.

Additionally, the bicycle fitting control system 100 may receive pressure data applied to the left and right sides of the saddle from the pressure sensor 10 provided on the saddle and calculate cadence data. Cadence data indicates the number of pedal steps per minute. That is, the bicycle fitting control system 100 can check the number of times a user pedals per minute by using the fact that when the user pedals, the user's body weight moves left and right and the hip bone also moves left and right.

Additionally, the bicycle fitting control system 100 may include a sensor. The sensor may include at least one of a GPS sensor, a gyro sensor, or an acceleration sensor. When equipped with a GPS sensor, the bicycle fitting control system 100 can estimate the gear ratio using GPS data and cadence data. The gear ratio is the rate at which the wheel rotates when one pedal is turned. At this time, the bicycle fitting control system 100 can estimate the gear ratio of the bicycle by complex calculating the speed and time values of the GPS value and cadence data.

Additionally, the bicycle fitting control system 100 can check the body weight load applied to the pedals using the estimated gear ratio. For example, when the gear ratio is higher than a preset reference value, the bicycle fitting control system 100 may determine that the load of body weight applied to the pedals is high, so the pressure applied to the hips and palms is low and the pressure is high to the knees. there is. In addition, the bicycle fitting control system 100 determines that when the gear ratio is lower than the preset reference value, the load of the body weight applied to the pedal is low, so the pressure applied to the hips and palms is high and the pressure applied to the knees is low. You can.

Additionally, the bicycle fitting control system 100 may determine whether to adjust cadence based on the estimated gear ratio. That is, the bicycle fitting control system 100 may determine that cadence adjustment is necessary when the gear ratio is lower or higher than the reference value.

When the bicycle fitting control system 100 determines that cadence adjustment is necessary, it may request the user terminal 20 to change the gear ratio. Additionally, the bicycle fitting control system 100 may generate handle fitting data and saddle fitting data based on the gear ratio when the user's pain cannot be alleviated even if the gear ratio is changed. Additionally, the bicycle fitting control system 100 may provide the generated handle fitting data and saddle fitting data to the user terminal 20.

Figure 2 is a diagram showing an example of a pressure sensor provided on a bicycle saddle and handle according to an embodiment of the present invention.

First, the pressure sensor can gently bend according to the curves of the bicycle seat, handlebar, and human body. The pressure sensor may be topped with a material such as memory foam that can distribute the user's pressure. In addition, the pressure sensor is provided with a thin waterproof cloth over the memory foam, etc., so that it is protected from moisture such as water or sweat and can be prevented from being damaged.

As an example, a plurality of pressure sensors (11a, 11b, 11c, 11d, 11e, 11f, 11g, 11h, 11i, 11j) may be provided on the left and right sides of the saddle. Pressure sensors 11b, 11c, 11d, 11e, 11g, 11h, 11i, 11j may be provided where the hip bone should be positioned accurately on the saddle. In addition, the pressure sensors (11a, 11b, 11c, 11d, 11e) provided on the left side of the saddle and the pressure sensors (11f, 11g, 11h, 11i, 11j) provided on the right side of the saddle measure pressure when the user pedals. The movement of data can be measured. The bicycle fitting control system can check the distribution of pressure on the buttocks and the user's posture based on the pressure data applied to the saddle. Additionally, the bicycle fitting control system can calculate cadence data using pressure data on the left and right sides of the saddle that moves according to the user's pedal driving.

The pressure sensors 11b, 11c, 11d, 11e, 11g, 11h, 11i, and 11j can measure pressure data applied by the user's hip bone to the saddle. The pressure sensors 11a and 11f may be provided at the frontmost position when the user sits on the saddle. The pressure sensors 11a and 11f can measure pressure data applied by the user's perineum and prostate.

As an example, a plurality of pressure sensors (12a, 12b, 12c, 12d, 12e, 12j, 12i, 12h, 12g, 12f) may be provided on the left and right sides of the handle. Pressure sensors 12a, 12b, 12c, 12d, 12e, 12j, 12i, 12h, 12g, 12f can be positioned exactly where the palm should be positioned on the handle. Additionally, the pressure sensors 12a, 12b, 12c, 12d, 12e, 12j, 12i, 12h, 12g, and 12f can measure pressure data applied to the handle. The bicycle fitting control system can check the pressure distribution on the hands and the user's posture based on the pressure data on the handlebars.

Figure 3 is a diagram showing the configuration of a bicycle fitting control system according to an embodiment of the present invention.

The bicycle fitting control system includes a communication unit 110, a sensor unit 120, a pressure data receiver 130, a cadence data calculation unit 140, a gear ratio estimation unit 150, a user posture data generation unit 160, and a fitting data generation unit. It may include unit 170.

First, the communication unit 110 provides a communication network to enable communication with the bicycle fitting control system, pressure sensor, and user terminal. For example, the communication unit 110 may use a wired communication network and a wireless communication network such as Zigbee, WiFi, or Bluetooth.

The sensor unit 120 may include a bicycle driving information measurement sensor. The bicycle driving information measurement sensor may include at least one of a GPS sensor, a gyro sensor, or an acceleration sensor. The bicycle driving information measurement sensor can obtain bicycle driving information by measuring bicycle driving information when the user drives the bicycle. At this time, the bicycle driving information may include at least one of location tracking information, angular velocity information, or acceleration information. For example, when the sensor unit 120 includes a GPS sensor, it can obtain location tracking information based on the time and distance of the bicycle. As will be described later, the gear ratio can be estimated based on GPS data obtained from the GPS sensor. Additionally, when the sensor unit 120 includes an acceleration sensor, it can obtain parking status information of the bicycle based on the acceleration sensor.

The pressure data receiver 130 may receive pressure data from a pressure sensor. Pressure sensors may be provided on the saddle and handle of a bicycle. The pressure data receiver 130 may receive pressure data applied to the saddle and handle of the bicycle when riding the bicycle. Pressure data may include pressure distribution applied to the saddle and handle.

The cadence data calculation unit 140 may calculate cadence data based on the received pressure data. Cadence data is a numerical representation of the number of pedaling times per minute. As an example, the cadence data calculator 140 may receive pressure data measured by pressure sensors provided on the left and right sides of the saddle from the pressure data receiver 130. When the bicycle rides, pressure may shift to the left and right of the saddle in response to the user's pedal operation. The cadence data calculation unit 140 may calculate cadence data based on the movement of pressure data applied to the saddle when riding a bicycle.

For example, the pressure sensor can transmit data at 30 frames per second to the pressure data receiver 130, and when converted to per minute, it is possible to measure up to 18,000 RPM. In general, it is almost impossible for a user to pedal 200 times per minute, so cadence data can be extracted from the pressure sensor without data loss.

The gear ratio estimator 150 may estimate the gear ratio based on the calculated cadence data and measured GPS data. The gear ratio is the rate at which the wheel rotates when one pedal is turned. The gear ratio estimator 150 can estimate the gear ratio regardless of wheel size by complex calculating the speed value and cadence data of GPS data. Additionally, the gear ratio estimation unit 150 can estimate a more accurate gear ratio when the wheel size is already registered. The gear ratio estimator 150 may provide the estimated gear ratio to the user terminal in real time. Additionally, since the gear ratio estimation unit 150 can estimate using cadence data measured based on pressure data, it is possible to present an accurate gear ratio even without synchronizing time values when linking data.

The user posture data generator 160 may determine the user's posture based on the received pressure data. As an example, the user posture data generator 160 may generate the user's posture data by checking the position of the user's hip bone based on pressure data. Additionally, the user data generator 160 may determine whether the user's hip bone is in the correct position on the saddle using the generated user posture data. Additionally, the user posture data generator 160 may generate the user's posture data by checking the position of the user's palm based on the pressure data. The user data generator 160 may determine whether the user's palm is in the correct position on the handle using the generated user posture data.

When the user posture data generator 160 determines that the user's hip bone or palm is not in the correct position, it may request a user terminal to change the user's posture. At this time, the user posture data generator 160 may request a change in the user's posture based on the generated user posture data. For example, when the user posture data generator 160 determines that the pressure distribution at the top of the saddle is high, it may generate user posture data in which the user's center of gravity is concentrated toward the top of the saddle and the handle. The user posture data generator 160 may determine that the height of the user's hips needs to be moved to the bottom of the saddle in order to lower the pressure applied to the user's perineum and palm. The user posture data generator 160 accurately presents the position and height of the user's hip bones, thereby correcting incorrect seating positions and reliably eliminating saddle pain.

Additionally, when it is confirmed that the pressure distribution of the palm applied to the handle is high, the user posture data generator 160 may generate user posture data in which the user's center of gravity is concentrated toward the handle. Additionally, the user posture data generator 160 may determine that the user's center of gravity needs to move from the handle to the saddle side by raising the upper body to lower the pressure applied to the wrist.

The fitting data generator 170 may include a handle fitting data generator 171 and a saddle fitting data generator 172. The handle fitting data generator 171 may generate handle fitting data based on the gear ratio. Additionally, the saddle fitting data generator 172 may generate saddle fitting data based on the gear ratio. The handle fitting data generator 171 may generate fitting data such as handle angle, handle length, and handle height based on the gear ratio. Additionally, the saddle fitting data generator 171 may generate fitting data such as the height of the saddle, the angle of the saddle, and the distance between the front and back of the saddle.

As an example, the handle fitting data generator 171 and the saddle fitting data generator 172 receive from the user terminal whether pain persists after changing the gear ratio, and generate handle fitting data and saddle fitting data when the user's pain persists. You can. A low gear ratio means that the wheel rotates less when one pedal rotation occurs, which results in the pedal spinning in vain. In other words, because the force applied to the pedal is low, the pressure applied to the palm and buttocks is high. If the handlebar is low, the user's weight moves forward, and the handlebar height must be adjusted because a greater portion of the body weight must be supported on the handlebar than on the saddle. At this time, the handle fitting data generator 171 may generate handle fitting data that increases the handle. In addition, a high gear ratio means that the wheel rotates a lot when the pedal rotates one turn, so the user puts all of his/her weight on the pedal to drive it, resulting in high pressure on the knee. Accordingly, the saddle fitting data generator 172 may generate saddle fitting data that increases the saddle to relieve knee pain.

In addition, the handle fitting data generator 171 may generate handle fitting data based on the user's body index. Additionally, the saddle fitting data generator 172 may generate saddle fitting data based on the user's body index. The body index may include the user's height, weight, arm length, and leg length. As an example, the handle fitting data generator 171 and the saddle fitting data generator 171 may receive whether pain persists after changing the posture based on user posture data from the user terminal. The handle fitting data generator 171 and the saddle fitting data generator 172 may generate handle fitting data and saddle fitting data based on the user's body index when the user's pain continues. Accordingly, the fitting data generator 170 may provide bicycle fitting data customized to the user's body.

Figure 4 is a diagram showing a configuration for storing data of a bicycle fitting control system according to an embodiment of the present invention.

First, the bicycle fitting control DB 180 includes the estimated gear ratio of the gear ratio estimator 150, the user posture data of the user posture data generator 160, the handle fitting data and saddle fitting data of the handle fitting data generator 171. The saddle fitting data of the generator 172 may be stored. If communication with the user terminal is possible through the communication unit 110, the bicycle fitting control DB 180 may delete data to be provided to the user terminal without storing it. Additionally, the bicycle fitting control DB 180 may store data to be provided to the user terminal when communication with the user terminal is not possible through the communication unit 110. Additionally, the bicycle fitting control DB 180 may provide stored data to the notification unit 190. When communication with the user terminal is possible through the communication unit 110, the bicycle fitting control DB 180 can provide the stored data to the user terminal and delete it.

The notification unit 190 may provide additional notifications to the user based on the received data. As an example, the notification unit 190 may use a warning device to deliver information through various types of warning sounds according to preset conditions. That is, when the user's gear ratio is high, the notification unit 190 can notify the user with a warning sound containing information that the gear ratio is high. As a result, the bicycle fitting control system can provide bicycle driving information to the user even in situations where the battery of the user terminal is exhausted or unusable. Accordingly, the user can change posture, adjust gear ratio, and control bicycle fitting in real time through additional notifications.

Figure 5 is a diagram illustrating an embodiment of fitting a bicycle based on handle fitting data and saddle fitting data of the bicycle according to an embodiment of the present invention.

As described above, handle fitting data and saddle fitting data may be generated based on the estimated gear ratio and user body index. First, the handle fitting data may include the length of the handle stem (171a), the height of the handle (171b), and the angle of the handle (171c). For example, if the saddle is high compared to the user's body index, pain may occur on the outside of the knee. At this time, handle fitting data that adjusts the height 171b of the handle based on the user's body index to relieve pain may be generated.

Saddle fitting data may include saddle angles (172a, 172b, 172e, 172f), saddle height (172c), and saddle length (172d). Additionally, the distance between the saddle and the handle can be adjusted based on the handle fitting data (171a, 171b, 171c) and the saddle fitting data (172a, 172b, 172c, 172d, 172e, 172f). For example, if the gear ratio is high, pain in the knees may occur. At this time, since the saddle must be moved upward in height to relieve pain, saddle fitting data that adjusts the height 172c of the saddle may be generated.

Therefore, the bicycle fitting control system can generate bicycle fitting data in real time using pressure data measured from pressure sensors attached to the saddle and handle and provide it to the user terminal. This solves the limitations of one-time fitting performed with conventional expensive fitting equipment, and allows fitting at any time in the environment and situation desired by the user.

Figure 6 is a diagram showing the overall flow of the bicycle fitting control system according to an embodiment of the present invention.

Referring to FIG. 6, in step S110, the bicycle fitting control system may receive pressure data from the pressure sensor. Pressure sensors may be provided on the saddle and handle. A plurality of pressure sensors provided on the saddle may be placed at positions corresponding to the hip bones, and a plurality of pressure sensors provided on the handle may be placed at positions corresponding to the hand bones. Each pressure sensor can measure pressure data applied at the deployed location.

In step S120, the bicycle fitting control system may generate user posture data based on the received pressure data. The bicycle fitting control system can use pressure data to determine the user's posture and generate user posture data based on this. As an example, the position of the user's hip bone can be determined based on pressure data from a pressure sensor placed on the saddle. Additionally, the angle of the user's upper body can be determined based on pressure data from the pressure sensor placed on the handle.

In step S130, the bicycle fitting control system may determine whether the user's posture has changed based on the generated user posture data. For example, if the bicycle fitting control system determines from the user posture data that the height of the user's hips is located at the top of the saddle, it may determine that the user's hips need to be moved to the bottom of the saddle. Additionally, when the bicycle fitting control system determines that the angle of the user's upper body is tilted toward the handlebar, it may determine that the user's upper body needs to move from the handlebar to the saddle side.

In step S140, when the bicycle fitting control system determines that a change in user posture is necessary, it may request a change in posture from the user terminal. Therefore, the bicycle fitting control system can determine the user's posture in real time based on pressure data and continuously guide the user to the optimal posture when a change in posture is necessary.

In step S150, when the bicycle fitting control system receives from the user terminal that pain persists even if the user changes his or her posture, the bicycle fitting control system may generate handle fitting data and saddle fitting data based on the user's body index. there is. The user's body index may include the user's height, weight, arm length, and leg length. The bicycle fitting control system can analyze pressure distribution and provide bicycle fitting appropriate for the user's body index. As an example, a bicycle fitting control system may generate saddle fitting data that can relieve knee pain based on the user's leg length. Additionally, the bicycle fitting control system can generate handlebar fitting data and saddle fitting data to reduce back and hand pain based on the user's height and arm length. Handle fitting data may include the length of the handle stem, the height of the handle, and the angle of the handle. Saddle fitting data may include saddle angle, saddle height, and saddle length.

In step S160, the bicycle fitting control system may provide the generated handle fitting data and saddle fitting data to the user terminal. Therefore, the bicycle fitting control system can induce the correct user posture based on pressure data applied to the handlebar and saddle when riding a bicycle. Additionally, the bicycle fitting control system can provide bicycle fitting data in real time based on user posture data and the user's body index.

In step S170, the bicycle fitting control system may calculate cadence data based on the received pressure data. Cadence data is a numerical representation of the number of pedaling times per minute, and can be calculated using the pressure sensor provided in the saddle. When riding a bicycle, pressure may shift to the left and right of the saddle in response to the user's pedal operation. At this time, the bicycle fitting control system can calculate cadence data by receiving pressure data movement from pressure sensors placed on the left and right sides of the saddle. For example, because pressure sensors can measure up to 18,000 RPM per minute, a bicycle fitting control system can extract cadence data without data loss.

In step S180, the bicycle fitting control system may estimate the gear ratio based on the calculated cadence data and sensor data. The gear ratio is the rate at which the wheel rotates when one pedal is turned. As an example, sensor data may include at least one of GPS data, acceleration data, or angular velocity data. The bicycle fitting control system can accurately estimate the gear ratio by complex calculation of cadence data and GPS data. The bicycle fitting control system can estimate the gear ratio regardless of bicycle wheel size by calculating speed data and cadence data from GPS data. At this time, if the bicycle wheel size is already registered, the gear ratio can be estimated more accurately.

In step S190, the bicycle fitting control system may determine whether to adjust the cadence data based on the estimated gear ratio. The bicycle fitting control system can compare the estimated gear ratio with a preset reference value. The bicycle fitting control system may determine that cadence data needs to be adjusted if the estimated gear ratio is smaller or larger than the reference value. For example, a low gear ratio means that the wheel rotates properly when one pedal wheel rotates, so the force applied to the pedal is low and the pressure applied to the palm and buttocks is high. Therefore, it can be determined that cadence data needs to be adjusted because pain may occur in the palms and buttocks. In addition, a high gear ratio means that the user puts all of his/her weight on the pedals to drive the pedals, which results in high pressure on the knees. Therefore, it may be determined that adjustment of cadence data is necessary to relieve knee pain.

In step S200, when the bicycle fitting control system determines that cadence data needs to be adjusted, it may request a gear ratio change from the user terminal. The bicycle fitting control system can request a change by lowering the gear ratio if the cadence data is high. Additionally, the bicycle fitting control system can request a change by increasing the gear ratio if the cadence data is low.

In step S210, the bicycle fitting control system may receive whether pain persists from the user terminal. The bicycle fitting control system can generate handlebar fitting data and saddle fitting data based on the gear ratio when the user's pain cannot be alleviated even if the gear ratio is changed. For example, a high gear ratio means that the user pedals with all of his or her body weight and the pressure applied to the knee is high, so saddle fitting data that increases the saddle can be generated. In addition, a low gear ratio means that a significant portion of the user's weight must be withstood on the handle rather than on the saddle while the pedals are spinning, so handle fitting data that increases the handle can be generated. The handle fitting data may include fitting data such as handle angle, handle length, and handle height. Additionally, the saddle fitting data may include fitting data such as the height of the saddle, the angle of the saddle, and the distance between the front and back of the saddle. In step S160, the bicycle fitting control system may provide the generated handle fitting data and saddle fitting data to the user terminal.

The bicycle fitting control system can determine the user's posture based on pressure data from pressure sensors provided on the handlebar and saddle. The bicycle fitting control system can use the identified user posture to continuously guide the user to maintain the correct posture while riding a bicycle.

Additionally, the bicycle fitting control system can calculate cadence data in real time based on the movement of saddle pressure data. The bicycle fitting control system can estimate the gear ratio by complex calculation of cadence data and GPS data. When the user's pain persists, the bicycle fitting control system can generate handlebar fitting data and saddle fitting data from the estimated gear ratio and user posture data. As a result, the bicycle fitting control system can provide customized bicycle fitting data without expensive equipment in the environment and situation desired by the user.

Figure 7 is a diagram illustrating a method of storing data of a bicycle fitting control system according to an embodiment of the present invention.

In step S310, the bicycle fitting control system may determine whether communication with the user terminal is possible. The bicycle fitting control system can use a wired communication network and a wireless communication network such as Zigbee, WiFi, or Bluetooth to communicate with the user terminal.

In step S320, when the bicycle fitting control system determines that communication with the user terminal is possible, it may delete the data to be provided to the user terminal without storing it. The bicycle fitting control system may provide user posture data, gear ratio, handlebar fitting data, and saddle fitting data to the user terminal.

In step S330, when the bicycle fitting control system determines that communication with the user terminal is impossible, it may store data to be provided to the user terminal. As an example, a bicycle fitting control system may include a database capable of storing 10 hours of data. At this time, the bicycle fitting control system may provide notification to the user of information stored in the database using an additional notification device. For example, a bicycle fitting control system is a warning device that can transmit information through various types of warning sounds according to preset conditions.

In step S340, the bicycle fitting control system may determine whether communication with the user terminal is possible. When the bicycle fitting control system determines that communication is not possible, it can continue to store data to be provided to the user terminal and provide additional notifications.

In step S350, when the bicycle fitting control system determines that communication with the user terminal is possible, it may provide data stored in the database to the user. Additionally, the bicycle fitting control system may delete the provided database data.

As a result, the bicycle fitting control system can provide bicycle driving information to the user even in situations where the battery of the user terminal is exhausted or unusable.
