1 and 2, the electromyography measuring system 100 of the present invention includes a fitness wear 110 and a portable terminal 130 worn by an athlete. The portable terminal 130 can measure the electromyogram of the exerciser using the signal provided from the electromyogram sensor mounted on the fitness wear 110 and display the measurement result so as to visually recognize the electromyogram.

First, the fitness wear 110 includes a wear body 10, a plurality of fiber electrode portions 111 attached to the wear body 10, a conductive pattern portion 113, and a control module 115.

The fiber electrode portion 111 is attached to the inner surface of the wear body 10. The fiber electrode unit 111 constitutes an electromyography sensor together with the control module 115 and is connected to the control module 115 through the conductive pattern unit 113.

The human body can measure the electromyogram or electrocardiogram by measuring the current of the small electric current and its current in the skeletal muscle according to the movement of the muscle. Electrocardiogram (ECG) specifically measures the current in the myocardium and its current change. When the wearer wears the fitness wear 110 of the present invention, the fiber electrode portion 111 directly contacts the skin and the current generated in the muscles according to the wearer's movement is transmitted to the control module 115 ).

The EMG measurement is performed by a method of amplifying the difference between the voltages of the + electrode and the - electrode based on the signal ground. Therefore, the positive electrode and the negative electrode must be attached to the muscle to be measured in one pair. 2, two (+ electrodes and - electrodes) are disposed in each muscle portion of the human body protected by the fitness wear 110 as shown in FIG. 2, and a signal ground portion for voltage measurement is disposed. The signal ground portion is made in the same manner as the fiber electrode portion 111, but its size is made sufficiently large to serve as a signal ground for the fiber electrode portion 111 for sensing.

The control module 115 amplifies the difference between the detected positive voltage and negative voltage and converts the sensed positive voltage and negative voltage into a digital signal. The control module 115, the conductive pattern part 113, And the fiber electrode part 111 form one electromyogram sensor. The actual EMG is calculated using the measurement values provided by the control module 115 of the portable terminal 130.

2, the control module 115 includes a sensor unit 201, a communication unit 203, a power supply unit 205, and a module control unit 207. The control unit 115 includes a conductive pattern unit 113, ) To measure the current for EMG measurement. The control module 115 converts the measured analog signal into a digital signal and transmits the digital signal to another portable terminal 130. The portable terminal 130 may be a mobile terminal carried by the wearer such as a smart phone or the like and the portable terminal 130 may calculate the EMG using the digital signal provided by the control module 115 And displays it to the wearer.

The communication unit 203 communicates with the portable terminal 130 in accordance with a predetermined communication protocol such as Bluetooth, Zigbee or NFC. The module control unit 207 controls the sensor unit 201 to detect the living body current at a predetermined cycle under the control of the portable terminal 130 and transmits the digital signal received from the sensor unit 201 to the communication unit 203 To the portable terminal 130 via the Internet.

The fitness wear 110 may be of various types such as an upper, lower or whole new type, a sleeveless type, etc., and the position of the fiber electrode portion 111 differs according to each type of fitness wear. On one side of each fitness wear 110, a barcode on which information on the type of fitness wear is recorded is printed or attached. Bar codes are not only conventional bar types, but also 2D bar codes such as QR codes. The control module 115 is commonly used for various kinds of fitness wears 110 by using the connection terminals 209. [

3, the portable terminal 130 includes a first wireless interface 301, a display unit 303, an input unit 305, a barcode reader 307 And a terminal control unit 310.

The first wireless interface 301 is an interface directly connected to the communication unit 203 of the control module 115 and may correspond to Bluetooth, Zigbee or NFC. Hereinafter, Bluetooth will be mainly described. The digital signal provided by the control module 115 is transmitted to the terminal control unit 310 through the first wireless interface 301 as described below.

In the case where the portable terminal 130 has a telephone function (for example, a smart phone), it may further include a wireless interface other than the first wireless interface 301. [

The display unit 303 is a device for displaying various information such as a LCD, an OLED and the like so that it can visually recognize various information. The input unit 305 is a device for receiving a user's control command. For example, it is preferable that the display unit 303 and the input unit 305 are provided in the form of a single touch screen.

The barcode reader 307 reads barcode 117 printed or attached to the fitness wear 110

And is provided with a camera (not shown) or may be configured to mount a high and external laser reader.

The terminal control unit 310 controls the overall operation of the portable terminal 130 and specifically includes a sensor control unit 311 and an event processing unit 313 for measuring EMG of the present invention.

The terminal control unit 310 may be a configuration specifically installed for the present invention, but may be a configuration that is installed to perform a main or basic function (e.g., telephone, communication, etc.) of the portable terminal 130 in general. In the case where the terminal control unit 310 is installed to perform the basic functions of the mobile terminal 130, the terminal control unit 310 includes a processor chip, which is hardware that is basically possessed by the mobile terminal 130, And may be a functional representation of a configuration implemented by an operating system (OS) software operating on the chip. In other words, the conventional terminal, to which the present invention is not applied, may also include the terminal control unit 310.

In this regard, the sensor control unit 311 and the event processing unit 313 may be installed in an existing terminal for the implementation of the present invention as an application which is software operating on the operating system program. In other words, when the sensor control unit 311 and the event processing unit 313 of the present invention are installed in a conventional portable terminal, the portable terminal becomes the portable terminal of the present invention.

Alternatively, the application may be software recorded on a computer-readable storage medium of a software distribution server (not shown), and the portable terminal 130 may be connected to a software distribution server (not shown) via a separate network And download and install the application (or software). An application for the sensor control unit 311 and the event processing unit 313 may be separately stored and managed and installed in the portable terminal 100. However, Or may be provided together.

When the sensor control unit 311 and the event processing unit 313 are installed in the portable terminal 130, the operation starts when there is an operation start control (icon click, etc.) of the user or an instruction.

The sensor control unit 311 stores and manages a 'sensor table' for each fitness wear type in a memory or a storage medium. Here, the sensor table stores information on the portion (or muscle portion) where the fiber electrode unit 111 is attached for each type of fitness wear for each fitness wear 110. In addition, the sensor table manages a predetermined reference EMG for each muscle portion. Here, the reference EMG corresponds to the EMG value when the corresponding muscle is in motion. The sensor control unit 311 receives from the event processing unit 313 the type of the fitness wear 110 worn by the user.

Since the sensor control unit 311 knows the type of the fitness wear 110, the sensor control unit 311 can recognize whether the digital signal provided by the control module 115 is measured by the fiber electrode unit 111 attached to the fitness wearer 110 And can be calculated by the EMG of the corresponding muscle portion. The control module 115 provides values measured through the plurality of pairs of fiber electrode units 111 so that the sensor control unit 311 can calculate the electromyograms of the plurality of muscle parts that can be measured when the fitness wear 110 is worn .

The sensor control unit 311 compares the calculated EMG with the preset reference EMG in the corresponding muscle portion, thereby confirming the muscle portion above the reference EMG. That is, the sensor control unit 311 can identify the muscle part that is stimulated by the current exercise. The sensor control unit 311 provides the measurement result to the event processing unit 313.

The event processing unit 313 reads the barcode printed or attached to one side of the fitness wear 110 using the barcode reader 307 and confirms the type of the fitness wear 110 worn by the user and sends the barcode to the sensor control unit 311 And displays on the display unit 303 the muscular part in which the electromyogram is measured to be greater than the reference EMG using the EMG measurement value provided by the sensor control unit 311 during the exercise.

The event processing unit 313 may display a plurality of exercise programs that can be performed according to the type of fitness wear selected by the user through the display unit 303 and may receive a user's selection through the input unit 305. [

The event processing unit 313 may display information on 'predicted muscle part' to be stimulated when the exercise normally proceeds based on the exercise program selected by the user through the display unit 303. [

The event processing unit 313 can display whether or not the muscle part stimulated by the exercise performed by the current user matches the expected muscle part based on the result of the electromyogram measurement provided by the sensor control unit 311. [ If the posture is erroneous even if the user exercises according to the exercise program, a portion other than the predicted muscle portion frequently occurs, and such a function of the event processing portion 313 is very effective in correcting the user's exercise posture.

4, a plurality of muscle parts a1, a2, b1, b2, c1, c2 and d corresponding to the fitness wear 110 of Fig. 1 are displayed on the screen 401 of the display unit 303. Fig. (C1, c2, d) in which the EMG value of the reference EMG equal to or higher than the EMG measured from the EMG measured by the sensor control unit 311 is represented by color and pattern , Shading, and the like. 4 shows that both the biceps brachii (c1, c2) and the rectus abdominis muscle (d) are in motion, indicating that there is more stimulation in the rectus abdominis muscle (d) than in the biceps brachii (c1, c2) .

Through the above-described methods, the event processing unit 313 manages the number of times of exercise and the order of each predicted muscle part in accordance with the exercise program while the exercise program selected by the user is performed, and stores the information provided by the sensor control unit 311 It is determined whether or not the exercise program selected as the basis is completed.

In addition, the event processor 313 checks whether a predetermined exercise program is completed, and then performs a predetermined end event when it is determined that the exercise program is completed. Here, the preset end event corresponds to playing a specific music or changing a music being played back.

Hereinafter, with reference to FIG. 5, a method of measuring an electromyogram based on the operation of the terminal control unit 310 of the present invention will be described.

<Checking the type of fitness wear: S501>

The user wears the fitness wear 110 and then reads the barcode 117 attached to the fitness wear 110 using the barcode reader 307 of the portable terminal 130. [ The barcode reader 307 provides the barcode read from the fitness wearer 110 to the event processor 313. [ The event processing unit 313 confirms the type of the fitness wear 110 based on the read barcode and provides it to the sensor control unit 311. [

<Selection of exercise program: S503>

The sensor control unit 311 displays a plurality of selectable exercise programs to the user through the display unit 303. When the user selects one of the exercise programs, the sensor control unit 311 displays an 'expected muscle portion' corresponding to the exercise program on the display unit 303, and may provide guidance for the exercise program itself.

<Exercise according to exercise program: S505>

When the user starts the exercise using the guidance for the exercise program displayed on the display unit 303, the sensor control unit 311 calculates the electromyogram for each muscle part by using the digital signal provided by the control module 115. [ The sensor control unit 311 compares the calculated EMG with the reference EMG of the corresponding muscle portion to identify the muscle portion above the reference EMG, that is, the muscle portion during exercise.

<Confirmation of end of exercise program: S507>

The event processing unit 313 determines whether the muscle part currently in motion corresponds to the anticipated muscle part based on the information provided by the sensor control unit 311 and counts the number of times the muscle part in motion is the anticipatory muscle part. The event processing unit 313 repeats steps S505 and S507 until the number of counts reaches the number of times of exercise (or the number of times of stimulation) of at least one muscle part set in the exercise program.

&Lt; End of exercise program: S509 >

When it is determined that the user-selected exercise program is completed based on the information provided by the control module 115, the event processing unit 313 performs the end event of the exercise program. For example, the terminal control unit 310 may request another configuration (for example, a sound source playback unit) of the terminal control unit 310 to change the currently playing sound source to another sound source, thereby indicating that the user selected the exercise program.

In this way, the electromyogram measuring method of the electromyography measuring system 100 of the present invention is performed.
