Description

The invention relates to shoes, characterized by the appointment, namely to the structural elements of the shoe, ensuring its tracking, which is a serious step to make life easier for people suffering from Alzheimer's disease or help parents to be aware of the movements of the child. The significant role of this development is due to the possibility of its practical application in tracking a person’s location using a radio module and a GPS tracker.

The prior art known insole with measuring weights for shoes (RU 96731U1, IPC A43B 3/00, A43B 17/00, publ. 08/20/2010]. The insole is a container that in some places has connected upper and lower walls, while the container is filled with liquid and connected to a mechanical measuring sensor or measuring instrument. The insole differs from the known ones because one or two layers of protective material are additionally applied on its external surfaces.

A disadvantage of the known insole is the absence in its design of elements for ensuring geolocation of shoes.

In addition, many portable GPS devices are now known. For example, a GPS tracker is known (US6198431B1, IPC G01C 21/20, G01S 1/00, G01S 19/27, G01S 5/14, publ. 03.03.2001], which is a lightweight compact portable receiver and GPS transmitter for use on while working outdoors, its disadvantage is the fact that it is easy to lose this device during a walk.

The closest technical solution to the claimed invention and selected as a prototype of recognized monitored shoes (RU2665902C2, IPC AV 4300, publ. 04.09.2018], which is based on the circuit terminal attached to the body and the movable component. Tracked shoes, in particular for children, contains:

- a circuit terminal permanently installed in the said shoe;

- a housing containing a first electrical contact connected to said circuit terminal;

- a movable component removably inserted into said housing, the movable component having a second electrical contact, said first electrical contact and a second electrical contact being configured to come into contact with each other depending on the insertion of said movable component into the housing.

A disadvantage of the known technical solution is the low reliability of the shoe due to the fact that its design contains moving parts.

The technical task, the solution of which the claimed invention is directed, is the possibility of detecting shoes when the owner of the shoes deviates from the walk route.

This problem is solved by the fact that footwear for people with disabilities contains typical elements, including left and right semi-pairs, each of which consists of a sole with a heel, equipped with a seal, with a top of a shoe fixed on it. What distinguishes shoes from known analogues is that the heel of the right half pair is hollow, containing an insulating element made of polyurethane, in which a control unit is installed, made on the basis of a microcontroller, equipped with first and second measuring inputs, first and second power outputs. A strain gauge attached to the inner surface of the heel is connected to the first measuring input of the control unit, a gyroscope is connected to the second measuring input, an LED strip attached to the outer surface of the heel is connected to the first power output, and a buzzer is connected to the second power output. A radio module and a GPS tracker connected to the first and second inputs of universal USART microcontroller universal synchronous-asynchronous transceivers of the control unit through bi-directional serial communication channels of the RS-232 data interface are installed in the heel.

A positive technical result of the claimed invention is the expansion of technical capabilities for the detection of shoes due to the use in its design of the control unit with a radio module connected to it, a GPS tracker, a buzzer and an LED strip along the heel. An additional technical result is the possibility of fixing the moment of putting on shoes by the owner due to the use of a strain gauge in the control unit design.

The invention is illustrated by drawings, where FIG. 1 shows the right semi-pair with the integration point of the GPS tracker in its heel, and FIG. 2 shows a simplified block diagram of the control unit.

Footwear for people with disabilities has the following design.

The footwear contains soles 1 with heels 2, fitted with heels 3, with shoe upper attached to it 4. The heel of the right semi-pair is hollow, containing an insulating element 5 of polyurethane, in which a control unit 6 is installed, made on the basis of a microcontroller 7, fitted with first and second measuring inputs 8 and 9, the first and second power outputs 10 and 11. To the first measuring input 8 of the control unit 6 connected strain gauge 12, mounted on the inner surface of the heel. A gyroscope 13 is connected to the second measuring input 9. An LED tape 14 is attached to the first power output 10, attached to the outer surface of the heel 2, and a buzzer 15 is connected to the second power output 11. The radio module 16 and the GPS tracker 17 are also connected to the heel the first and second inputs of the universal synchronous-asynchronous transceivers USART 18 and 19 of the microcontroller 7 of the control unit 6 through bi-directional serial communication channels of the RS-232 data exchange interface.

As a microcontroller, an AVR-based chip can be used, for example ATMega128L ¹ ( ¹ ATMega128 Architecture // Microelectronics Market URL: http://www.gaw.ru/html.cgi/txt/doc/ micros / avr / arh128 / 20 .htm (appeal date: 03/21/2019)). As a strain gauge, any known one can be used, for example, BF350-3AA BF350 ² ( ² BF350-3AA STRAIN GAUGE MODULE // Hobby components URL: https://hobbycomponents.com/documents/963-bf350-3aa-strain-gauge- module (access date: 03/21/2019)). As a gyroscope, a digital three-axis accelerometer GY-291 can be used on an ADXL345 ³ microcircuit ( ³ GY-291 Module 3-axis accelerometer (13 bits) ADXL345 (RKP-GY-291-ADXL345) // Robot-kit URL: http: //robot-kit.ru/product info.php/info/p1169 Modul-GY-291-3-h-osevoi-akselerometr - 13-bit-ADXL345-RKP-GY-291-ADXL345-.html (the date of circulation : 21.03.2019)). The assembly of the НС-11 ⁴ can be used as a radio module ( ⁴ НС-11 Radio module // RoboShop URL: http.//roboshop,spb,ru/CC1101-HC11 (access date: 21.03.2019)), and as GPS tracker G229 ⁵ ( ⁵ GPS Tracker for Arduino do it yourself // Habr-habr.ru URL: https://habr.com/ru/en/post/196150/ (access date: 03/21/2019)). For attaching the heel to the sole, it is advisable to use rubber glue of the brand “Desmokol” ⁶ ( ⁶ Polyurethane glue Desmokol for shoes // kakley.ru URL: https://kakkley.ru/plue-polyurethane-desmocolk-for-I / (circulation date: 03/21/2019)).

The microcontroller 7 (Fig. 2) includes a microprocessor 20 connected via a common bus with a FLASH program memory, a SRAM data memory (conventionally not shown in the figures), a ten-bit analog-to-digital converter 21, universal eight-bit bidirectional I / O ports 22 , 23 and 24, as well as the above mentioned first and second universal synchronous asynchronous transceivers USART 18 and 19. The first measurement input 8 of the control unit 6 is made on the basis of an operational amplifier and connected to the analog-to-digit input A new converter 21. A second measurement input, made in the form of current-limiting resistors, 9 is connected to the first bi-directional I / O port 22. Power outputs 10 and 11 are made on the basis of transistor switches, while the first power output 10 is connected to the second I / O port 23 , and the second power output 11 is connected to the third I / O port 24.

Shoes for people with disabilities are used as follows.

As mentioned above, a hollow molded heel made of thermoplastic was chosen as the place for the integration of shoe detection units. As an additional insulation of the control unit, the radio module and the GPS tracker from external factors on the inside of the heel, an insulating element made of polyurethane is used. In addition, heel heels are made of wear-resistant materials, to prevent them from wear. The heel is fixed to the sole of the shoe with the use of the adhesive method, preliminarily setting it in place of gluing, then using the screw through the heel cushion, reinforce the heel. When fixing the heel, as noted above, it is advisable to use rubber glue for shoes of the Desmokol brand.

During use of the shoe as intended, the owner puts pressure on the heel 2 equal to its weight, while the strain gauge 12 detects the deformation of the shoe and the force applied to it and transfers its value to the input of the measuring input 8. The microprocessor 20 in accordance with the control program written in the program FLASH-memory (conventionally not shown in the figures), performs force measurement using an analog-to-digital converter 21. After detecting the moment that the shoe wears the owner, microprocessor 21 starts naet constant poll gyro 13 in order to control the spatial coordinates of footwear and the radio module 16, waiting for control commands from an external remote control (in the figures is not shown).

The owner of the shoe or the person accompanying it, using the control panel, can turn on the LED tape 14. The LED tape 14 fixed on the heel will illuminate the shoes, increasing the safety of wearing them in the dark.

The gyroscope 13 will respond to a change in the orientation of the body in space from vertical to horizontal. In the latter case, registering the possible fall of the owner, the control unit 6 with the help of the buzzer 15 gives a warning signal to the owner. If after five seconds the gyroscope 13 does not fix the restoration of the body orientation to the vertical, the control unit 6 using the radio module 16 transmits the alarm signal and the current geographical coordinates of the owner's location, recorded using the GPS tracker 17, to the remote control.

Thus, the footwear disclosed in this application extends the ability to control the location of persons with disabilities or children, which generally improves the safety of walks.
