Description

The utility model relates to the field of combating terrorism by technical means.

There are various types of anti-fragmentation blankets and anti-fragmentation blankets (for example, the anti-fragmentation blanket "UYUT" - http://www.divecon.net/catalog/lokalizatory-vzryva/protivooskolochnoe-odeyalo-uyut/), designed to reduce the high-explosive and fragmentation effects in an explosion improvised explosive devices.

The tactics of using such means are as follows - when a suspicious object is found, which may contain a VU, such an object is covered with an anti-splinter blanket (blanket), as a result of which the “negative effect” is reduced to 70%.

The prototype is a protective structure of a splinterproof blanket with a gas-filled material (patent RU (11) 2200293 - (https://yandex.ru/patents/doc/RU2200293C1_20030310), containing layers of woven and nonwoven materials with increased ballistic resistance, characterized in that the layers of woven and nonwoven materials are separated by layers of gas-filled material with closed pores, which does not form damaging fragments under explosive loading, having an apparent density of 10 ... 100 kg / m ³ , tensile strength of at least 0.5 MPa, and the total thickness of the gas-filled material is 0.5 … 5.0 times the thickness of the nonwoven fabric.

This anti-splinter blanket (blanket) is quite effective, but it has certain drawbacks - in the case of using a VU controlled by a radio channel, it will in no way help against such initiation. Although, according to experts, the use of such VU is very likely (as the specialist of the Ministry of Internal Affairs Shogenov TG in his article "MODERN MOBILE MEANS OF SUPPRESSING EXPLOSION CONTROL RADIO LINES: STATE AND NEW REALITY", the scientific journal "International Journal of Applied and Basic Research" states, that, based on the materials of practice, 55% of all VUs were controlled by a radio channel, mainly in the VHF range - https://applied-research.ru/ru/article/view?id=10247).

The objective of the claimed utility model is to reduce the likelihood of initiation (control) over the radio channel of a VU localized by means of a splinterproof blanket (blanket) of a dangerous object.

The technical result is to improve safety for the population.

The problem is solved by the fact that on the inner side (the one that covers the suspicious object) of the splinter blanket (bedspread), a radio signal blocker (noise generator) is installed in the range from 20 MHz to 3000 MHz (VHF band as the most likely to be used by an intruder, see. article by Shogenov T.K.). The blocker is designed to generate various types of interference: barrage, aiming, masking, flickering, diverting, response. In this case, the interference can be used both jointly and separately.

The declared anti-splinter blanket contains the main layer of material. On the inner side of the main material layer, at least one radio signal blocker is installed, made in the form of a noise generator in the range from 20 MHz to 3000 MHz. The radio signal blocker is designed to generate various types of interference: barrage, sighting, masking, flickering, diverting, response, while the interference is used both jointly and separately. The radio signal blocker is designed to be activated remotely using wired and wireless means. The blocker of radio signals is configured to turn on with a time delay.

As the main layer of the material, a single-layer or multi-layer anti-splinter material, for example, based on Kevlar, can be used.

As a blocker, various models of blockers can be used, for example, specially made to block possible control commands of the RVU, or other blockers of signals (noise generators), made with the possibility of generating various types of interference: barrage, sighting, masking, flickering, diverting, response, the interference is used both jointly and separately, in the range from 20 MHz to 3000 MHz.

Currently, there are already some types of such blockers "Pelena-8U" (http://kobra.su/catalog/nosimyj/item/174-pelena-8u/) with blocking frequencies from 20 to 3500 GHz.

Such blockers RVU are made in order to block the communication of a whole large area, the blocker that will be used in the proposed device will be located in the immediate vicinity of the possible receiving-initiating device of the WU and, therefore, can be made much less powerful (with lower spectral power), which will have certain advantages before use over standard RVU blockers (the power of which can reach up to 100 W):

1) reduction in weight and dimensions;

2) significantly longer battery life;

3) the use of a low-power blocker as part of an anti-splinter blanket (blanket) will practically not lead to communication interference in the local area.

Mathematical modeling carried out by the author showed that when the blocker is placed from the receiving device in the 400-500 MHz range at a distance of 15 cm and the transmitting device is at a distance of 200 meters, for a significant decrease (up to 90%) the probability of receiving commands from the transmitting device, a blocker power of no more than 5 W is sufficient (against 60-100 W of standard blockers for these purposes).

To increase the likelihood of blocking the control signal of the VU, such blockers can be placed in different parts of the splinter blanket (blanket). Also, for the safety of the operator, a remote activation of the blocker or activation with a certain delay can be provided.

The device works as follows.

If a suspicious object is found, it is covered with an anti-splinter blanket. To reduce the likelihood of initiation via the radio channel of a radio-controlled VU, possibly located in a suspicious object, one or more blockers of signals in the range from 20 MHz to 3000 MHz are turned on. The blocker (s) are located on the inside of the splinter blanket (blanket) and their emitting antenna is approximately directed towards the suspicious object. To increase safety, such activation of the blockers should be done remotely or with a time delay, when all persons are at a sufficiently safe distance.

If the VU does work (for example, it is initiated at a certain time with the help of a clock mechanism), the splinter blanket reduces the harmful effects on people or material objects.
