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

1 is a block diagram of an exercise amount confirmation and location tracking device built in the shoe according to an embodiment of the present invention.

As shown, the exercise amount confirmation and location tracking device built in the shoe, the pressure sensor 100, the power supply 200, the speaker 300, LED 400, the communication chipset 500, the antenna 600 consist of.

The pressure sensor 100 outputs a voltage variably according to the amount of pressure when a user of a shoe puts on a shoe and a pressure is applied thereto. In addition, the pressure sensor 100 minimizes power consumption by generating a wake-up interrupt signal to the communication chipset 500 when the user starts walking in shoes. I did it.

Next, the power supply unit 200 is for supplying power to the communication chipset 500, a pressure oscillator 210 and a pressure oscillator 210 for outputting a charging voltage according to the amount of pressure when the pressure is applied The battery 220 is configured to be charged by the charging voltage output from the battery 220 to provide the charging voltage to the communication chipset 500.

When the user of the shoe starts to walk wearing the shoe, the pressure oscillator 210 is driven accordingly to charge the battery 220, and the charging voltage charged in the battery 220 is supplied to the communication chipset 500.

The speaker 300 outputs sound in accordance with a sound source control signal output from the communication chipset 500.

Next, the LED 400 emits light according to a light emission control signal output from the communication chipset 500 and may blink the user's eyes.

Here, the speaker 300 and the LED 400 can be seen as a location notification means, the speaker 300 outputs a sound when the sound source control signal is input as a location notification control signal to inform the location, LED 400 When the light emitting control signal is input as the position notification control signal, the light is notified of the position.

Meanwhile, the communication chipset 500 includes an analog-digital converter 510, a wireless communication unit 520, and a controller 530.

The analog-to-digital converter 510 converts an analog voltage input from the pressure sensor 100 into a digital voltage and outputs the digital voltage. For example, as illustrated in FIG. 2, an analog voltage input from the pressure sensor 100 is 0 to 0. FIG. Converts to a digital value between 3V and outputs. In FIG. 2, the digital value ranges from 0 to 3V. Each scale is divided into 0.1V units, and the current output value represents 1.7V.

In addition, the wireless communication unit 520 transmits and receives data to and from the portable terminal 700 through a short range communication method through the antenna 600. At this time, the short-range communication method that the wireless communication unit 520 can use is Zigbee, RFID, Bluetooth, and the like. Of course, as will be described later, in order to provide a location tracking function when the device of the present invention from the mobile terminal 700 is a long distance away, the wireless communication unit 520 can transmit and receive data such as a base station, a router, etc. In this case, CDMA, Communication methods such as WCDMA, HSDPA, and Wibro can be used.

Next, the controller 530 calculates and outputs a weight corresponding to the pressure value of the pressure sensor 100 output from the analog-to-digital converter 510 when the user of the shoe wears the shoe and is in a landing state. .

To this end, the factory initially sets the weight for each of the digital values corresponding to the pressure values of the pressure sensor 100 to produce a product.

However, even when the factory sets the weight for each of the digital values corresponding to the pressure value of the pressure sensor 100 in the factory as described above to produce a product, when the actual shoe user uses such a function, the mobile terminal 700 Occurs when the weight displayed and displayed is different from the user's weight.

Therefore, in the present invention, the user can use the portable terminal 700 to correct the difference between the initially set weight and the actual weight, which will be described with reference to FIG. 3 below.

3 is a flowchart illustrating a weight error correction process in the communication chipset of FIG. 1.

First, when the user wears shoes (S110) and the digital value corresponding to the pressure value measured from the pressure sensor 100 in the landing state is output from the analog-to-digital converter 510, the digital value is output to the output value. Accordingly, the initially set weight is transmitted to the mobile terminal 700 to be displayed on the display unit (S112).

Then, the user checks the weight displayed on the mobile terminal 700 (S114), and determines whether or not to match their weight (S116), if the match is terminated and if it does not match the weight of the communication chip ( In step S118, the control unit 530 transmits the control to the control unit 530 of FIG.

As such, the control unit 530 that receives the weight of the user from the mobile terminal 700 changes the setting value for the initial digital value to the received weight, and then calculates and outputs the weight according to the changed setting value (S120).

For example, when the user's weight is actually 62 kg, and the weight displayed on the mobile terminal 700 is 70 kg when the user wears shoes and lands (for example, the output value of the analog-to-digital converter 510 is 1.7 V). , Correction is necessary.

Accordingly, when the user informs the control unit 530 of the communication chip 500 of the actual weight 62kg using the menu provided in the portable terminal 700, the control unit 530 corrects the difference in weight (that is, When the output value of the analog-to-digital converter 510 is 1.7V, the output is corrected to 62 kg).

On the other hand, the controller 530 calculates and outputs the number of steps by counting the number of times of crossing the specific threshold value when the digital value according to the pressure change of the pressure sensor 100 is input from the analog-to-digital converter 510.

When the user walks wearing shoes, the digital value according to the pressure change of the pressure sensor 100 will be described with reference to FIG. 4, which shows the digital value according to the pressure change of the pressure sensor 100 over time. Each time the number of steps is counted, the counted value is multiplied by 2 (if only one shoe is equipped with the device of the present invention and multiplied by 2 to consider the number of steps of the other foot), the number of steps is calculated and output.

In addition, the control unit 530 outputs a sound through the speaker 300 when there is a request for location confirmation from the mobile terminal 700, or emits and flashes the LED 400 so that the user easily finds the position of the shoe. Do it.

The location tracking function of the shoe is used to find a shoe in a dark place or a restaurant with a lot of shoes, and the user is located in the control unit 530 of the communication chipset 500 through a menu operation of the mobile terminal 700. The confirmation request signal is transmitted, and accordingly, the controller 530 outputs a sound through the speaker 300 or emits and blinks the LED 400 so that the user can easily find the shoe.

However, such a location tracking function can be used only when the mobile terminal 700 and the wireless communication unit 520 provided in the communication chipset 500 transmit and receive data through a short range communication method, and are located at a short distance, that is, long distance, that is, far away. It cannot be used if it is separated.

Therefore, in the present invention, when the communication chip set 500 mounted on a shoe sends a signal to an intermediate router such as a base station in the long distance, the signal is analyzed to determine the location of the user who is wearing the shoe in a location tracking method such as a triangulation method. It can be traced.

The location tracking method at a long distance is illustrated in FIG. 5. As illustrated in FIG. 5, when a user such as a child wears shoes and is in a park, the control unit 530 of the communication chipset 500 may include three base stations or the like. It periodically signals the router.

Then, the location tracking server 800 receives the reception sensitivity received from the three base stations or routers, and tracks the location of the shoe in a well-known method such as a triangular measurement method and transmits it to the mobile terminal 700.

In this case, the parent of the young child can easily find the position of the child by looking at the position of the shoe displayed on the mobile terminal 700.

On the other hand, the mobile terminal 700 receives and displays the weight and the number of steps transmitted from the wireless communication unit 520 of the communication chipset 500. In this case, the mobile terminal 700 may directly display the number of steps as an exercise amount, or may display the amount of exercise as a distance (unit: m) by multiplying the number of steps that an adult can move on an average step. .

In addition, the portable terminal 700 transmits the weight input by the user to the communication chipset 500 to correct the initial weight. In addition, when the user requests a shoe position check using a menu to track the shoe position, the mobile terminal 700 transmits a position check request signal to the communication chipset 500 accordingly. In addition, the mobile terminal 700 displays the location transmitted from the location tracking server 800 so that the parent of the child can identify the location of the child.

The portable terminal 700 performing such a function may be a PDA, an MP3, a mobile phone, or the like.

6 is an exemplary diagram in which the exercise amount checking and position tracking device according to an embodiment of the present invention is embedded in a shoe.

Referring to the drawings, the pressure sensor 100 and the pressure oscillator 210 of the momentum check and position tracking device is embedded in the shoe heel, the communication chip 500 is also embedded close to the shoe heel.

As such, when the pressure sensor 100 and the pressure oscillator 210 are built in the heel of the shoe, the pressure sensor 100 and the pressure oscillator 210 may be positioned at the strongest portion of the shoe to measure the user's weight most effectively.

Then, the speaker 300 is installed to be built in the front of the heel of the shoe, the LED 400 is installed to be exposed to the outside in front of the heel of the shoe.

As such, when the speaker 300 and the LED 400 is installed in front of the shoe heel, the user can clearly hear the sound, and the flicker of the LED 400 can be easily confirmed.

The antenna 600 is located above the shoe and installed to be exposed to the outside so that the antenna 600 can be easily transmitted and received without interfering with the wireless signal, and the mobile terminal 700 is maintained as close as possible.
