Description

The utility model relates to devices for isolating explosive or suspicious objects, namely by preventing the initialization of an explosive device in them, the detonator of which is wirelessly controlled.

There are various devices for preventing the detonation of radio-controlled explosive devices (VU).

For example, to block possible control commands for radio-controlled explosive devices (RVU), you can use all kinds of radio communication blockers, which are currently produced by Russian and foreign industries in a large number. For example, "Pelena-8U" (http://kobra.su/catalog/nosimyj/item/174-pelena-8u/).

The prototype is a device for preventing the initialization of an explosive device (RF Patent No. 195713, published: 02/04/2020, bul. No. 4), made in the form of a protective dome containing a layer of fabric and made with the ability to cover a suspicious object with the dome, while the dome is made in the form frame, moreover, a fabric is used as a fabric, shielding from electromagnetic interference, and inside the dome, a false base station is installed and fixed to the dome, capable of simulating digital standards for wireless data transmission from the group: GSM, GPRS, EDGE, DECT, BLUETOOTH, WLAN.

However, this device only simulates certain communication standards, including cell phones, namely (as indicated in the description) digital standards for wireless data transmission from the group: GSM, GPRS, EDGE, DECT, BLUETOOTH, WLAN. At the same time, the accidental activation of the timer for the initialization of the explosive device is excluded if it does not see the signals of the required communication standard. The base station ST121 (http://www.alt-1c.ru/pages.html?id=5&cat=145&item=1545) can be used as a simulator (as indicated in the description) - the type of base stations that simply emit communication packets , similar to some communication systems (GSM, GPRS, EDGE, DECT, BLUETOOTH, WLAN).

The disadvantage is that this solution does not accurately prevent explosion if the command is issued in frequency ranges not covered by these standards. According to experts in this field, radio stations of very high frequencies and ultra-high frequencies (VHF-UHF) are used to control VU in a large number of cases (Shogenov T.G. Modern mobile means of suppressing radio lines for controlling an explosion: state and new reality, scientific journal " International Journal of Applied and Basic Research "p. 339 (https://applied-research.ru/ru/article/view?id=10247)), and, as you know, the VHF-UHF range is the range from 20 MHz to 3 GHz.

The objective of the claimed utility model is to increase the probability of preventing an explosion when using RVU.

The technical result is to improve safety for the population.

The problem is solved by the fact that in the device for preventing the initialization of an explosive device, made in the form of a protective frame of the dome with the ability to cover the dome of a suspicious object, the frame of the dome is made of a layer of material, and the material used is a fabric shielding from electromagnetic interference, according to the claimed technical solution a blocker of radio signals in the range from 20 MHz to 8000 MHz is installed inside the dome. The frame of the dome can be made foldable, inflatable. The blocker is designed to be activated remotely using wired and wireless means. The 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 device for preventing the initialization of an explosive device is made in the form of a protective frame of the dome with the possibility of covering a suspicious object with the dome. The frame of the dome is made of a layer of material, and the material used is a fabric that shields from electromagnetic interference (for example, this - https://el-kor.ru/bezehovye-kamery-i-ekrankamery-ekraniruyushchie-materialy/aaronia-x-dream -tkan-ekraniruyushchaya-ot-elektromagnitnyh-pomeh-100-db), allowing you to block signals up to 30 GHz. A blocker of radio signals in the range from 20 MHz to 8000 MHz is installed inside the dome. The frame of the dome can be made foldable, inflatable. The blocker is designed to be switched on remotely (using both wired and wireless means). The blocker is made with the ability to generate various types of interference: barrage, sighting, masking, flickering, diverting, response. In this case, the interference can be used both jointly and separately. As a material of the dome, metal sheets of aluminum, copper, nickel, iron and silver, as well as their alloys can be used (https://el-kor.ru/bezehovye-kamery-i-ekrankamery-ekraniruyushchie-materialy/aaronia-magnoshield -dur-plastinalist-dlya-ekranirovaniya-silnyh-magnitnyh-poley). The dome material can be aluminum or copper foil. It is known that to control VU (and block the frequencies of their operation) in a greater number of cases, radio stations of very high frequencies and ultra-high frequencies (VHF-UHF) are used in the range from 20 MHz to 3 GHz (Shogenov T.G. Modern mobile means of suppressing radio lines explosion control: state and new reality, scientific journal "International Journal of Applied and Fundamental Research" p. 339 (https://applied-research.ru/ru/article/view?id=10247)).

Example. The following experiments were performed.

1) Into a sealed dome of a cylindrical shape (a tank with a height of 75 cm), shielded with two layers of shielding fabric (like this - https://el-kor.ru/bezehovye-kamery-i-ekrankamery-ekraniruyushchie-materialy/aaronia-x-dream -tkan-ekraniruyushchaya-ot-elektromagnitnyh-pomeh-100-db) was placed radio station LPD radio station - frequency range 433-434 MHz, maximum power up to 5 W. A second radio station of the same type provided signal transmission. As a result, it was found that signal transmission is possible at a distance of 8 to 20 meters (depending on the orientation of the radio equipment, the connection either appeared or disappeared).

2) In the course of the next experiment, the above-mentioned radio stations were also used, only they were now located 70 cm from the blocker of this range (for the blocker, frequencies 433 MHz, 315 MHz, 868 MHz, 869 MHz were used, the total output power was 10 W (jammer.su )). As a result of the experiment, signs of an emerging connection were observed at distances from 3 to 12 meters (depending on the orientation of radio equipment in space, the connection appeared and then faded).

3) During the final experiment, the above bollard was placed inside the sealed cylindrical dome (from point 1) and fixed at the top. The distance between the blocker and the radio station did not exceed 70 cm. As a result of the experiment, signs of an emerging connection were observed at distances from 0.2 to 1.5 meters.

Thus, it can be argued that when the blocker is placed inside a dome shielded with fabric, a "certain" synergistic effect is observed. This is because radio waves do not travel outside the shielded dome, but are reflected and folded inside the dome, which also affects the additional blocking efficiency. Therefore, when using a bollard inside such a shielded dome, it (the bollard) can be significantly smaller in size with the same efficiency (you can also reduce the power and increase the battery life).

Therefore, the use of a bollard inside the dome, made in the form of a protective dome containing a layer of fabric and capable of covering the suspicious object with the dome, provides the following advantages:

1) reduction in weight and dimensions;

2) significantly longer battery life;

3) unlike a bollard without a dome, no permission is required for use (since the signal from the bollard “under the dome”, due to the use of one or several layers of radio-opaque tissue, will practically not come out from under the dome;

4) the use of blockers under the dome will not lead to the disconnection of all wireless communication in the local area, unlike conventional blockers, since the signal from the blocker "under the dome", due to the use of one or several layers of radio-opaque fabric, will practically not come out from under the dome.

Application tactics - a suspicious object (bag, etc.) is covered from above with a dome made of radio-opaque fabric, and the above-described radio signal blocker is placed inside.
