The insole 100 is provided for the left foot and the right foot, respectively. In the present invention, if necessary, the insole 100 for the right foot or the left foot will be described as an example.

And the pressure sensor unit 200 is provided in the insole 100. The pressure sensor unit 200 is configured to measure the pressure applied from the user's sole.

At this time, the pressure sensor unit 200 may be a foot pressure sensor capable of measuring foot pressure.

Here, the pressure sensor unit 200 is not limited to a specific shape or structure, and may be formed in various shapes capable of measuring the foot pressure of a user.

The pressure sensor unit 200 may be entirely disposed on the insole 100.

Therefore, foot pressure measurement can be made at any point where the user's sole and the insole 100 abut.

The pressure sensor unit 200 may divide regions into regions of a predetermined region where the pressure sensor is disposed. The pressure sensor part 200 may be divided into a first area part 210, a second area part 220, a third area part 230, a fourth area part 240 and a fifth area part 250. have.

Here, the first region portion 210 to the fifth region portion 250 may be divided into regions for each foot pressure portion that is pressed based on the bone of the human foot.

For example, the first region 210 may be a region in which the calcaneus region is pressed based on the bone of the foot. In addition, the second region 220 may be a region in which the cubic bone region is pressed based on the bone of the foot.

In addition, the third region 230 may be a region in which the region of the metatarsal bone 1 is pressed from the metatarsal bones 4 and 5 based on the bone of the foot. In addition, the fourth region portion 240 may be a region in which the thumb stun is pressed.

In addition, the fifth region 250 may be a region where the thumb fracture region is pressed based on the bone of the foot.

As such, the pressure sensor unit 200 may be divided into first region parts 210 to fifth region parts 250 for each foot pressure part that is pressed based on the bones of a person's foot.

On the other hand, although the pressure sensor unit 200 as described above has been described as being integral with the insole 100, it may be separate from the insole 100 as shown in FIG. 4.

The separable pressure sensor unit 200 shown in FIG. 4 is a metal fiber sensor coated with a mesh and supplies power to the pressure sensors of the first region 210 to the fifth region 250 at the edge. The power supply terminal 270 is formed.

The pressure sensor 200 is not limited to this, and one carbon atom is combined with three other carbon atoms to form a hexagonal honeycomb pattern, and a carbon nanotube material formed by rolling a net having a corresponding hexagonal honeycomb pattern in a cylindrical shape Can also be made with

As described above, according to the present invention, as the pressure sensor 200 is formed of a carbon nanotube material, it is possible to implement the pressure sensor 200 having a more compact, faster, and better performance.

In addition, the carbon nanotubes can be used as a super-strong fiber or a surface material that is resistant to heat and friction because the bond between carbon atoms is much stronger than silicon, very strong in air, and has chemically stable properties.

In particular, since the pressure sensor 200 of the present invention frequently generates heat and friction according to the pedestrian's walking, it is highly preferable to use the carbon nanotube that is resistant to heat and friction as a material for the pressure sensor 200. .

Meanwhile, it is preferable that a power supply terminal 120 corresponding to the power terminal 270 is formed on a surface of the insole 100 positioned under the pressure sensor unit 200.

That is, when the pressure sensor unit 200 is stacked on the insole 100, the power terminal 270 of the pressure sensor unit 200 contacts the power supply terminal 120 of the insole 100 to supply power. Power of 400 may be supplied.

As described above, the smart walking management system according to the present invention is provided with the pressure sensor unit 200 as a separate type independent from the insole 100, so that when the failure occurs in the pressure sensor unit 200, the insole 100 ) It is possible to reduce the management cost by replacing only the pressure sensor unit 200 without having to replace the whole.

Meanwhile, the communication unit 300 is configured to transmit pressure information measured from the pressure sensor unit 200 to the external device 1.

The communication unit 300 may establish a communication connection with the external device 1 through short-range communication technologies such as ZigBee, Near Field Communication (NFC), and Bluetooth.

At this time, the external device 1 may be any one of a smart phone, a portable terminal, a personal digital assistant (PDA), a portable multimedia player (PMP), a notebook computer, and a tablet PC. The external device 1 can be used with any terminal that can communicate with the communication unit 300.

In particular, as another embodiment, the communication unit 300 may be inserted into and installed in the communication unit installation hole 130 formed in the insole 100 as shown in FIG. 5.

At this time, the main control unit 700 may be further formed at the position of the communication unit 300 of FIG. 3.

More specifically, the communication unit installation hole 130 is formed in the arch portion in which the pressure of the sole of the foot is relatively less than that of the other parts of the insole 100, so that the inserted communication unit 300 is applied by the user's sole to walk. The pressure can be prevented from being damaged by pressure.

 Meanwhile, the smart walking management system according to the present invention further includes an electric power generating unit 600 interposed between the insole 100 and the pressure sensor unit 200 of a metal fiber coated with a mesh type as shown in FIG. 6. It is characterized by.

The power generating unit 600 is composed of a piezoelectric element that is a semiconductor element that converts a physical force (vibration) into an electrical signal, and generates power by receiving pressure applied as a pedestrian walks.

The power generating unit 600 has an electrode 610 at a corresponding position of an edge so that it can contact the power terminal 270 of the pressure sensor unit 200 and the power supply terminal 120 of the insole 100. It is preferably formed.

As the pedestrian walks, the electricity generated by the power generation unit 600 is transferred to the power supply unit 400 made of a secondary battery and charged, or the pressure sensor unit 200 that requires power immediately or It may be supplied to the communication unit 300 and the like.

 On the other hand, the power generating unit 600 is easily detachable to and mounted on the insole 100, and may be mounted on the insole 100 or detached if necessary.

For example, when a pedestrian needs to walk for a long time, it is preferable to walk in a state in which the power generating unit 600 is mounted when all of the power charged in the power supply unit 400 is discharged and charging is not feasible.

Conversely, when a pedestrian walks for a short time, it is preferable to walk after removing the power generating unit 600 when the power supplied to the power supply unit 400 is sufficient to supply power.

In addition, the power supply unit 400 is configured to supply power to various components mounted on the insole 100. For example, the power supply unit 400 may be supplied with power for the operation of the communication unit 300 or power may be supplied to the pressure sensor unit 200.

The power supply unit 400 may be made of a secondary battery that is used semi-permanently through charging. Here, the power supply unit 400 does not necessarily have to be made only of a secondary battery, and any form may be used as long as it is possible to supply power to various components mounted on the insole 100.

The communication unit 300 and the power supply unit 400 are installed in the installation space groove 110 formed in the insole 100. Here, in one embodiment of the present invention, the installation space groove 110 is described as being formed in the arch portion of the insole 100 as an example, but the installation space groove 110 must be formed only in the arch portion of the insole 100 Of course, it can be formed in various parts of the insole 100, of course.

Meanwhile, the walking analysis unit 500 is configured to analyze pressure information measured from the pressure sensor unit 200. That is, the walking analysis unit 500 analyzes the user's walking state through pressure information transmitted from the communication unit 300.

The gait analysis unit 500 may be installed in the external device 1. For example, the external device 1 may be a smartphone, and the user may install the walking analysis unit 500 on the smartphone through an app. Therefore, the user can check his / her walking state through the smartphone.

Here, the walking analysis unit 500 installed in the smartphone is made to enable the user to select a mode according to a standing, walking or running state. For example, the walking analysis unit 500 may be made to select various modes such as a standing mode, a normal walking mode, a fast walking mode, and a running mode.

In addition, the mode selection may be selected by a user's hand touch through the gait analysis unit 500, but is also possible through the main control unit 700 formed on the insole 100.

That is, it is possible to select the walking mode by a combination of the number of times the user lifts the forefoot and touches only the heel on the ground.

More specifically, when the user touches the heel on the ground, a signal pressed to the first area unit 210 of the pressure sensor unit 200 located at the back is transmitted to the main control unit 700, and the main control unit 700 In the walking signal 500, a standing mode, a normal walking mode, a fast walking mode, and a running mode are selected from the gait analysis unit 500 to analyze the selected mode.

For example, a signal in which the heel is touched once is in a standing mode, a signal in which the heel is touched twice is a normal walking mode, a signal in which the heel is touched three times is a fast walking mode, and a signal in which the heel is touched four times is in a running mode. The main control unit 700 is signal-processed and transmitted to the walking analysis unit 500 so that analysis of a corresponding mode can be performed.

The gait analysis unit 500 analyzes a user's gait state through pressure information measured by the pressure sensor unit 200.

Specifically, when the gait analysis unit 500 walks once, the first area unit 210, the second area unit 220, the third area unit 230, the fourth area unit 240, and the fifth area When the sequential movement of the foot pressure is shown in the order of the unit 250, the gait analysis unit 500 determines that the user's correct gait is achieved. At this time, the gait analysis unit 500 is recognized as the correct gait only for the foot pressure intensity greater than a predetermined pressure to the first region portion 210 to the fifth region portion 250.

For example, if it is determined that the correct gait is performed based on the one gait, the gait analysis unit 500 may be configured to add one point. The gait analysis unit 500 may calculate the respective scores for the left foot and the right foot.

Through this method, the gait analysis unit 500 calculates the correct number of walks compared to the total number of walks. For example, if 100 walks are made, if the correct gait of the left foot is 95 and the correct gait of the right foot is 98, the gait analyzer 500 calculates the correct number of gaits compared to the total number of gaits, and the correct gait of the left foot is 95%. It is analyzed that the correct gait of the right foot is 98%.

In addition, the gait analysis unit 500 may be configured to analyze the cause of the incorrect walking. For example, it is possible to analyze the cause, such as the foot pressure intensity in the third region 230 being less than a predetermined pressure among 5% of the causes of failure of correct walking during the walking of the left foot. As described above, the data results analyzed from the gait analysis unit 500 where correct gait is not achieved may also be used as gait treatment data for correct gait.

Here, the walking analysis unit 500 is configured to input various user information such as a user's height and weight. Accordingly, the gait analysis unit 500 sets the foot pressure intensity to be applied to the first area portion 210 to the fifth area portion 250 according to the user information, and is recognized as correct walking only for the foot pressure intensity above the set pressure. Is done.

In addition, a notification function for notifying the user of an abnormal abnormal walking may be added to the walking analysis unit 500.

For example, the gait analysis unit 500 may notify the user that the correct gait is not achieved by sound or light at a point where the correct gait is not achieved. When such a notification is generated, the user may walk slowly and correct his or her walking posture.
