Description

BACKGROUND OF THE INVENTION Field of the Invention [0001]

The present invention relates to an apparatus and method for displaying a momentum, which detects a motion using a six-axis or nine-axis sensor, analyzes motion information to determine whether or not to exercise, and counts and displays the momentum as the number of times.

Recently, a variety of exercise solutions for diet and body management have been presented through the Internet and other media, and systems for u-Healthcare have been proposed, which can be used at specific times and places, It is a system that continuously measures various biometric information such as user's heart rate, blood pressure, body temperature, and movement and remotely monitors such information to enable active treatment and health care.

Korean Patent Laid-Open No. 10-2013-0058026 " Momentum Quantity Display Device " is disclosed as a conventional health care system. It can display the number of exercises and calories consumed provided from a fitness device, A calorie consumed by the exercise can be known, so that it is possible to perform an interesting exercise and to provide various moving pictures related to the exercise method.

However, such a conventional exercise quantity display device is to detect the movement of the exercise device by the sensor member to calculate the exercise quantity, and the exercise quantity display itself is limited to the exercise device, and the user can not know the exercise quantity indicator for various body movements There are disadvantages.

Korean Patent Laid-Open No. 10-2013-0089796 discloses an arm motion measurement system based on a wireless sensor network. The arm motion measuring system includes a motion measurer attached to a user's arm to measure movement of the arm and collecting measured motion data, a motion sensor connected to the motion sensor and a wireless sensor network (WSN) A gateway for relaying a signal so as to enable information exchange between the motion measuring device and another device, and a terminal carried by the user, wherein the terminal receives the motion data from the relay through wireless communication, And a mobile server device for measuring the arm movement and the energy consumption, and by providing an auxiliary service specialized for the dumbbell curl, which is an indoor weight arm movement, the number of exercises corresponding to the physical characteristics of the individual So that accurate dumbbell curl motion can be induced to the user It characterized.

However, the arm motion measurement system uses an acceleration sensor as a motion detector to be worn on an arm. In the motion measurement using the acceleration sensor, only the acceleration information can be used, and only the momentum can be measured. The acceleration sensor measures linear acceleration and tilt angle. The acceleration sensor alone can sense only the rotation between horizontal and vertical at a fixed position. With this sensor, it is possible to estimate simple momentum, but it can not measure complex motion.

That is, the conventional arm motion measurement system can measure and display the number of movements using a measurement algorithm in the case of a dumbbell curl motion having a simple directional repetitive motion.

However, in general, since the reference value of each axis for the exercise type must be changed, it is necessary to receive only the selection input of the user's exercise type. The output data of the sensor module varies depending on the wearing area.

In the case of using the acceleration sensor, since the upper and lower threshold values of the respective measurement algorithms must be changed, it is possible to separately measure the number of times of exercise when the kind of the exercise is different. Therefore, different measurement algorithms must be provided for each exercise type, It is possible to measure a simple momentum in the corresponding motion. Also, depending on the type of exercise, it may happen that the exercise information can not be precisely classified and measured only by the acceleration sensor.

Typically, during a fitness exercise, several sets of exercises to perform several kinds of exercises successively several times for each exercise kind are repeatedly exercised. In the case of using the acceleration sensor as described above in the case of the set motion, there is a problem that the exercise is interrupted because the exercise type must be set and operated for each exercise type.

The motion determination and display control module of the momentum display terminal analyzes the received data, And a motion amount display method for counting and displaying the number of times of exercise,

A calibration step (S10) of receiving movement data from an operation measuring device and setting a reference position for motion identification when a start button or a calibration button is input;

A motion axis having the greatest motion among the X, Y, and Z axes with respect to a reference position after the calibration is performed, and a motion axis and a motion direction are set by sensing whether the motion direction of the motion axis is an increase direction or a decrease direction, (S20) of automatically setting an angle range for a motion range and a motion direction;

The step of counting the number of times of exercise (S40)

When the motion axis and the direction angle set in the motion determination information setting step S20 are newly changed and set, if the setting of the motion axis and the direction angle is repeated within the predetermined count number, it is determined as the set motion, Thereby displaying the number of set movements.

The gyro sensor 111 and the acceleration sensor 112 are installed in the operation measuring device 100 and the detection signals of the gyro sensor 111 and the acceleration sensor 112 are detected by the microprocessor 120 And transmits it to the momentum display terminal 200 through the communication module 130. The wearer 150 is installed in the body part of the user so that the user can wear the body part of the quaternion data (X, Y, Z, W) It should be worn on the body part for measurement of momentum. It is preferable to use a wearing means such as a band-type Velcro tape because the wearing position of the wearing means 150 is different.

The acceleration sensor 112 measures the linear acceleration and the tilt angle. The acceleration sensor 112 alone can detect only the rotation between the horizontal and vertical directions at a fixed position. With this sensor, it is possible to estimate simple momentum, but it can not measure complex motion. Accordingly, the present invention uses a gyro sensor 111 to measure complex motion. The gyro sensor 111 can precisely measure the rotation and the direction even with complicated movements.

The geomagnetic sensor 113 may further include a geomagnetic sensor 113, which can be used to measure an absolute direction using a geomagnetic sensor, thereby further improving the measurement accuracy. In the 9-axis sensor, more accurate operation can be measured by using the geomagnetic sensor to correct the output value of the gyro and acceleration sensor.

Therefore, the present invention can accurately read a user's complex motion by using a six-axis or nine-axis sensor. This makes it possible to determine not only the amount of momentum but also whether or not the exercise is correct. The output format of the motion measuring device 100 is a quaternion and the communication module 130 is transmitted to the momentum display terminal 200 using a Bluetooth module. That is, various repetitive movements (ex: push-up, squat, dumbbell movement) using the body with the 9-axis sensor can be counted without any special setting.

The momentum display terminal 200 may be a mobile communication terminal such as a smart phone or a terminal equipped with a communication module 210 for wireless communication with the communication module 130 of the motion measuring device 100. [ In the momentum display terminal 200, a motion measurement and display control module 220 is installed as an application program. The motion measurement and display control module 220 analyzes motion data received from the motion measurement device 100 to determine motion, counts the number of motions, Display the momentum.

The motion measuring device 100 is worn on the body part for measuring the momentum, and the motion data is measured by wearing the body part where the displacement is greatly generated during the exercise. When the motion measurement and display control module 220 of the momentum display terminal 200 is operated, the menu buttons and the display window 224g are displayed on the screen as shown in FIG. 3, and the device list button 224a is displayed on the menu button portion 224. [ The communication between the operation measuring device 100 and the same-quantity display terminal 200 is automatically set up. When the connection button 224b is pressed, communication connection is established and the quaternion data detected by the operation measuring device 100 Motion data is transmitted to the momentum display terminal 200 in real time.

The motion determination and display control module 220 receives the quaternion quaternion data transmitted from the motion measuring device 100 from the data receiving unit 221 by changing the Euler angle data.

 The calibrating unit 222 sets a reference position at the start of the exercise and performs calibration for correcting the received data to the amount of displacement according to the reference stitch. The menu button unit 224 of the exercise determination and display control module 220 displays a calibration button (E.g., 5 seconds) at the time of inputting the corresponding button, and automatically calibrates the received data based on the reference position information to perform calibration .

In another embodiment, when the start button 161 is provided to the operation measuring device 100 and the start button is input, the motion detection control unit 120 performs calibration by using the momentum display terminal 200 through the communication module 130 It is possible to cause the calibration unit 222 to perform the reference position setting and the calibration of the received motion data.

It may be troublesome for the user who starts the exercise to operate the exercise amount display terminal 200 to press the calibration button and then move to the exercise position to start the exercise. In order to solve such a complication, when the operation measuring device 100 is provided with a start button for a calibration instruction, the button input of the motion measuring device 100 worn without departing from the exercise position is calibrated, .

The exercise quantity counter 223 analyzes the movement data on which the calibration is performed, generates motion, determines the repeatability, and counts the number of times of exercise. First, the axis with the greatest movement among the movements of the X, Y, and Z axes is set as the motion axis, and the direction of movement is determined by determining whether the motion of the corresponding motion axis is the increase direction or the decrease direction. Then, the motion range and the angular range are automatically set to the motion judgment range according to the motion axis and the motion direction.

Then, it is determined whether motion in the motion axis and the motion direction is out of the motion determination range. If the motion data exceeds the motion determination range, it is determined that the motion is performed.

Then, it is judged whether or not the exercise is returned within the allowable range after the exercise is performed, and when it is returned, it is determined that one exercise is completed, and the number of times is counted and displayed.

The present invention is advantageous in that it is not limited to a specific exercise and there is no need to select an exercise item. There is no great restriction on the sensor attachment site. However, when you exercise, you can usually wear a motion measuring device on a moving joint.

The present invention gives time to hold the exercise posture for 5 seconds by pressing the calibration button. After 5 seconds, the user will be able to perform the desired exercise. At this time, the movement of the user's first motion is read to determine how much the rotation of the axis moves and returns. Based on the detected information, it is judged that the exercise is performed when the movement is within the error range. With this algorithm, the number of repetitive motions can be automatically counted without inputting the user's sports item or sensor attachment site.

The present invention receives quaternion data from an operation measuring device 100, converts the quaternion data into Euler data, and determines the number of movements with an angle of x, y, and z axes.

The rotation value of the sensor is initialized by pressing the calibration button on the momentum display terminal 200 (i.e., mobile) receiving the output of the sensor after wearing the motion measuring device on the part (arm, leg, head, chest,

First, when the movement is first performed after calibrating, it determines whether the movement of the joint corresponds to which axis of the x, y, or z axis, and determines whether the direction of movement is + direction or direction.

According to the first detected axis and direction, when it exceeds the predetermined angle, it is judged that the exercise is performed, and when it returns to the starting point of the exercise, counting is performed. With this algorithm, only the motion you want to count can be counted accurately.

For example, when the push-up is performed after the calibration, the axis of the angle that changes greatly in the first movement is set as the main axis, and the angle of the axis is set to a certain range or more. If the user pushes up, the forward or side-to-side motion is excluded from the count due to this algorithm.

The present invention further comprises a sound output unit 227 for outputting a sound or counting sound output each time the count number is increased by the control of the main control unit 226 when displaying the exercise amount count count. Accordingly, the number of times of counting during exercise can be output as sound or count voice.

The sound output unit 227 may be installed in the operation measuring device 100 to output a counted sound or a counted sound under the control of the motion detection control unit 120 so that the communication module can perform bidirectional communication. The main control unit 226 of the momentum display terminal 200 transmits the count information to the operation measuring device 100 and the count information received from the motion detection control unit 120 of the operation measuring device 100 So that the sound or count audio output can be controlled. That is, a sound output unit may be configured in the operation measuring device so that a count sound or voice is output from the operation measuring device.

Meanwhile, the integrated momentum display apparatus according to the present invention may include a microprocessor provided with a motion determination and display control module installed in the momentum display terminal, a microprocessor installed as a program, and a monolithic structure . That is, the integrated device is configured so that the motion measuring device itself can measure and display the momentum without using the smart terminal.

In the following description, the reference numerals in the drawings denote the same components as those in Figs. 1 and 2 and those in Figs. 5 and 6, and the integral momentum display device is denoted by reference numeral 300 .

The integrated momentum display device (300) of the present invention comprises:

A momentum counter (223) for counting the number of motions by judging the motion based on the rotation light direction information whose filtering is controlled by the calibration section (222);

A display control unit 225 for outputting and displaying the counted number of times of exercise on the display 230;

A plurality of menu buttons for operating the momentum measuring apparatus are provided through the display 230 and the motion detection control unit 120, the data receiving unit 221, the calibration unit 222, Which controls the operation of each part of the exercise determination and display control module 220 for starting the measurement of the amount of exercise and determining and displaying the amount of exercise by controlling the display of the exercise amount 223, the display control part 225 and the display 230, And a control unit (226).

In addition, the integrated momentum display device 300 includes a start button 161 for transmitting a control command to start the exercise count together with automatic calibration after a predetermined time elapses after the start is input, a reset button 162, and an operation status indicator 163.

And a menu button provided by the software.

In the integrated type momentum display apparatus thus constructed, the integrated momentum display device 300 is worn on a motion measurement site where a displacement occurs according to the motion of the user's body, and after a predetermined time (for example, 3-5 seconds) During the preparatory phase, start exercising. At the time when a predetermined time for taking the ready position after the start button is inputted, the current position and attitude information is set as the reference position information, and calibration for automatically setting the range for determining the motion, that is, the filtering information, is performed .

After the calibration is performed, the motion detection information is filtered to determine whether the motion returns to the original reference position after the motion is generated beyond the set motion range, and the motion number count is increased and displayed on the display 230. Of course, the return to the reference position is not returned to the correct position but is returned to within the range set in the filtering range, thereby recognizing whether or not to return.

Therefore, since the reference position may be changed according to the movement of the movement, it is preferable to perform the re-calibration to set the return position, that is, the reference position every time and reset the filtering range accordingly.
