Abstract

FIELD: personal protective equipment.

SUBSTANCE: invention can be used to ensure the safety of pedestrian movement in conditions of enemy mining. The essence of the invention is that a search coil is integrated into a soldier’s standard footwear at the manufacturing stage, the conducting turns of which are fused into the outer contour of the sole, connected to a power supply and a control unit, which, when parameters change indicating the presence of metal objects, mines, in the immediate vicinity, generates alert signals. The triggered alarm has an irritating effect on a person, causing a response in form of an unconditioned reflex to prevent placing a foot on a detected metal object, a mine.

EFFECT: detect of mines and prevention of placing a foot on it due to reflexive action.

Description

The alleged invention relates to personal protective equipment and can be used to ensure the safety of pedestrian movement in conditions where the enemy is mining the area.

The proposed invention has no analogues in its purpose.

The proposed invention solves the problem of detecting a mine at the site where the foot is supposed to be planted and preventing contact with it.

There is a known invention, patent CA 2210868 A1, which protects against the damaging effects of mine explosives by placing the foot at a height of at least 5 cm due to the frame. The invention is also known, RF 2090123, which provides protection against injury by attaching a shock-absorbing and energy-absorbing module made of composite materials to the foot. The disadvantage of both options is the impossibility of their use outside of mine clearance tasks. The proposed invention is distinguished by a method of protection against mine blast damage by preventing it, as well as by the possibility of mass and everyday use due to minor differences from standard shoes in terms of weight and size characteristics.

The technical result of the proposed invention is to detect a mine and prevent placing a foot on it due to reflexive action.

The essence of the invention is that a search coil is integrated into a soldier’s standard footwear at the manufacturing stage, the conductor turns of which are fused into the outer contour of the sole, connected to a power supply and a control unit, which, when changing parameters indicating the presence of metal objects in the immediate vicinity, generates alert signals. The triggered alarm has an irritating effect on a person, causing a response in the form of an unconditioned reflex to prevent placing a foot on a detected metal object.

The implementation of the invention is presented in Figures 1-4.

In Fig. Figure 4 shows the appearance of the product, where 1 is a control unit with a battery, 2 is a connection unit for an external headset (headphones), 3 is a receiving coil.

The operating principle is shown in Fig. 5, where:

1 - search coil. Under the influence of a current of a certain frequency, it generates an electromagnetic field. Used as a metal object detector. It can be implemented both according to the principle of a single-coil circuit (Fig. 1), and according to the “receive-transmit” circuit (Fig. 3), or on another principle.

2 - control unit. Supplies control signals to the search coil to generate an electromagnetic field and records the operating parameters of the search coil. When changing parameters indicating the presence of metal objects in the immediate vicinity, it generates alerts.

3 - power supply.

4 - switch. Designed to disable the circuit when moving around industrial facilities, being in cars and armored vehicles, rooms and other places with multiple metal soil contamination.

5 - siren. It has an irritating effect on a person causing a response in the form of an unconditioned reflex to prevent placing a foot on a detected metal object. In experimental samples, vibration was applied to the middle lower part of the foot. Additionally, light and sound notification is possible, including using peripheral devices.

6 - connector for connecting peripheral devices.

7 - operator.

The implementation of the proposed invention is possible on the basis of standard military footwear (high-top boots). The control unit can be implemented on the basis of similar blocks of hand-held induction metal detectors. The search coil can be implemented in the form of turns of copper wire wound on a ferrite core, or in another way that ensures that the required parameters are achieved. The battery is selected based on the requirements for the control unit supply voltage, current consumption and operating conditions. The annunciator in the experimental model was implemented in the form of a signal supply device based on the generation of vibration signals transmitted to a person through the skin of the lower extremities. For this purpose, the experimental model used a vibration device in the form of a micromotor with an eccentric on the shaft. To prevent habituation to the effects of the irritating factor, the frequency and strength of vibration were chosen to remain unchanged, and the duration and operating period of the signal varied depending on the degree of proximity to the detected object. Thus, when using a physical stimulus with these characteristics, a person without obvious pathologies will have an unconditioned reflex that will unconsciously prevent the operator from placing his foot on the initialized object.

Claims (1)

Mine-resistant shoes that warn the operator that the foot is approaching a metal object, a mine, and prevent contact with it, characterized by the fact that a mine detector is integrated into the shoes, consisting of a control unit, a power source, a search coil and an annunciator, which is a micromotor with an eccentric on the shaft, wherein the turns of the search coil conductor are fused into the outer contour of the sole and connected to a power supply and a control unit, which, when changing parameters indicating the presence of metal objects or mines near it, is capable of generating warning signals that have an irritating vibration effect transmitted to a person through the skin lower extremities on the middle part of the foot, causing a response in the form of an unconditioned reflex that prevents placing the foot on a metal object, a mine, and the frequency and strength of vibration are unchanged, and the duration and working period of the signal can be changed depending on the degree of approach to the metal object, mine.
