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 main body 10, a plurality of fiber electrode portions 101 attached to the wear main body 10, a conductive pattern portion 103, and a control module 105.

The fiber electrode portion (101) is attached to the inner surface of the wear body (10). The fiber electrode unit 101 constitutes an electromyography sensor together with the control module 105 and is connected to the control module 105 through the conductive pattern unit 103.

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 fibrous electrode portion 101 directly contacts the skin, and the current generated in the muscles according to the wearer's movement is transmitted through the conductive pattern portion 103 to the control module 105 ).

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. As shown in FIG. 2, the fiber electrode unit 101 is provided with two signal electrodes (+ electrode and -electrode) in each muscle region of the human body protected by the fitness wear 110 and a signal ground unit for voltage measurement. The signal ground portion is made in the same manner as the fiber electrode portion 101, but its size is made sufficiently large to serve as a signal ground for the fiber electrode portion 101 for sensing.

The control module 105 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 105, the conductive pattern part 103, And the fiber electrode portion 101 form one electromyogram sensor. The actual EMG is calculated using the measurement value provided by the control module 105 by the portable terminal 130.

The control module 105 is mounted on one side of the inner surface or the outer surface of the fitness wear 110.

2, the control module 105 includes a sensor unit 201, a communication unit 203, a power supply unit 205, and a module control unit 207. The control unit 105 includes a conductive pattern unit 103, ) To measure the current for EMG measurement. The control module 105 converts the measured analog signal into a digital signal and transmits the digital signal to another portable terminal 130. The mobile 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 105. [ 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.

An athlete may have a plurality of fitness wears 110, such as top, bottom, or front. However, the control module 105 is commonly used for various types of fitness wears 110 by using the terminals 209. [

Hereinafter, configurations that are not essential to the description of the present invention are not shown in the drawings and are not described.

Although the portable terminal 130 of the present invention is connected to the control module 105 of the fitness wear 110 described above, the present invention is not limited to the fitness wearer 110 shown in FIGS. 1 and 2, The conductive pattern part 103 is not limited to being mounted on the wear body 10 as if it were a part of the fiber. In other words, the portable terminal 130 of the present invention can operate with a control module 105 connected to an electrode unit (not shown) directly attached to a human body.

3, the portable terminal 130 includes a first wireless interface 301, a display unit 303, an input unit 305, and a terminal control unit 310 to perform the EMG measurement and display of the present invention .

The first wireless interface 301 is an interface directly connected to the communication unit 203 of the control module 105 and may correspond to Bluetooth, Zigbee or NFC. Hereinafter, Bluetooth will be mainly described. The digital signal provided by the control module 105 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 terminal control unit 310 controls the overall operation of the portable terminal 130 and includes a sensor control unit 311 and a display control unit 313 in order to measure the 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 functionally indicating a configuration implemented by an operating system (OS) 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 respect, the sensor control unit 311 and the display control unit 313 may be installed in an existing terminal for implementing the present invention as an application which is software operating on the operating system program.

Here, the sensor table stores information on the portion (muscle region) where the fiber electrode unit 101 is attached for each fitness wear for each fitness wear. In addition, the sensor table manages predetermined 'reference EMG' for each muscle region. Here, the reference EMG corresponds to the EMG value when the corresponding muscle is in motion.

The sensor control unit 311 calculates the electromyograms of the respective muscle parts using the digital signals provided by the control module 105. [ Since the control module 105 provides the measured values through the plurality of pairs of fiber electrode units 101, 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 reference EMG for each muscle region to identify the muscle region above the reference EMG. That is, the sensor control unit 311 can identify the muscle region that is stimulated by the current exercise. The sensor control unit 311 provides the measurement result to the display control unit 313.

The display control unit 313 displays the muscle part on which the EMG is measured beyond the reference EMG on the display unit 303. [

[ The display control unit 313 can provide the sensor control unit 311 with information on the fitness wear selected by the user.

In addition, the display control unit 313 may display a plurality of selectable motion types through the display unit 303 and receive a user's selection through the input unit 305. [ The display control unit 313 may display information on 'anticipated muscle region' to be stimulated when the exercise normally proceeds based on the kind of exercise selected by the user through the display unit 303. [ Further, the display control unit 313 can display whether the 'predicted muscle region' and the muscle region determined by the sensor control unit 311 to have measured the EMG more than the reference EMG coincide with each other.
