Abstract

FIELD: radio engineering.

SUBSTANCE: invention relates to radio engineering; it can be used to detect radiation sources in large-sized objects. A device includes a spatial structure, a shell of which is entirely or at least a layer of the shell is made of radio-opaque material. Equipment is installed inside the spatial structure, signals from which are transmitted via wired or wireless communication to a control computer. A virtual base station is used as equipment. The spatial structure is erected above or outside an object being examined. In the latter case, the object being examined is transported inside it on its own or in another way.

Description

The invention relates to radio engineering, in particular to devices for detecting radio transmitting devices installed in large objects, for example, cars, and can be used to establish the fact of covert installation of eavesdropping, tracking and explosive devices.

Radio transmitting devices can be used for covert recording of acoustic and video information with its subsequent transmission or in real time to a remote receiving device.

Also known are radio transmitting devices called GPS trackers and designed to track the location of an object, such as a car. The coordinates of the object are usually transmitted via the Internet or SMS-messages.

To control explosive devices, radio transmitting devices are also often used (URL: / https: //applied-research.ru/ru/article/view? Id = 10247, date accessed: 16.06.2020).

Searching for and locating radio transmitting devices is complicated by the fact that these items can be found in large objects, such as cars or buildings.

It is known that a large number of the above-described radio transmitting devices operate using cellular communications.

The prototype is a device for preventing the initialization of an explosive device (https://yandex.ru/patents/doc/RU195713U1_20200204), made in the form of a protective dome containing a layer of fabric and made with the possibility of covering a suspicious object with the dome, characterized in that the dome is made in the form frame, moreover, 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. Such an imitation (as indicated in the description, they create an imitation of digital standards for wireless data transmission from the group: GSM, GPRS, EDGE, DECT, BLUETOOTH, WLAN, so that the timer for the initialization of the explosive device does not accidentally turn on if it does not see the signals of the required communication standard. as indicated in the description) base station ST121 can be used [http://www.alt-1c.ru/pages.html?id=5&cat=145&item=1545] This is a 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 allow you to say for sure whether a digital device (for example, a GSM cellular communication) is in a suspicious object or not (since it is not intended to create a two-way information exchange with devices, including GSM). In addition, it cannot be used to inspect bulky items such as a car.

The objective of the claimed utility model is to more accurately determine whether a cellular communication device is located in a large-sized object.

The technical result is to improve safety for the population.

The technical problem to be solved by the present invention is the detection and possible identification of radio transmitting devices of cellular communication - secretly installed sources of radio emission - in large-sized objects.

The solution to the technical problem posed is achieved through the use of a temporary structure (for example, a tent or a tent) in the search for radio transmitting devices, erected over the surveyed large-sized object or placing a large-sized object in a different way under this temporary structure (roll up, drag, etc.), and the shell of the building is made or contains a layer of radio-opaque fabric, shielding from electromagnetic interference, and the use of equipment installed inside the building to register electromagnetic radiation (radio emission).

As equipment, it is proposed to use a virtual base station of cellular communication (VBS) with the ability to conduct two-way information exchange with devices using cellular communication.

The principle of operation of such devices has been known from the prior art for a long time, for example, it is described in this article (date of access 07/03/2020 https://habr.com/ru/company/securitycode/blog/280886/). The link provides the finished product - VBS (date of treatment 07/03/2020 https://www.mascom.ru/equipment/poiskovoe-oborudovanie/kompleksy-vyyavleniva-besprovodnykh-sredstv-dostupa/ibs-2g.php)

As indicated in the above description of this device, it forcibly automatically transfers the cellular communication devices located in the room under its control. As a result, it is the devices using cellular communication that are determined with 100% probability, and it is also possible to determine some possible identifiers of these devices.

The construction is proposed to be carried out entirely or using one or several layers of radio-opaque fabric or other shielding material such as Aaronia X-Dream (URL: / https: //www.test-expert.ru/catalog/detail.php? ID = 16 & SECTION_ID = 33, date of access: 23.06.2020).

The proposed invention is illustrated by a drawing (Fig. 1), in which the positions indicate: 1 - inspected large object, 2 - building, 3 - blocker, 5 - VBS, 6 - control computer. FIG. 1 shows the option of the largest configuration of the proposed device - option "c)".

The proposed device for detecting sources of radio emission in large objects works as follows.

Building 2 is being erected around a large-sized object 1, which is subject to inspection for the presence of secretly installed sources of radio emission. In the case of an examination of a car or other vehicle that can be moved under its own power or in any other way inside building 2, building 2 is erected in a free place, close to the object being inspected, after which the latter is transported on its own or in another way inside the erected building, or it is erected directly over a vehicle if it is impossible or unsafe to move it.

The form of the building, its architectural features and the method of construction are not subject to protection under this application.

A short-term activation of the blocker 3 is possible (to activate the "sleeping" radio transmitting devices).

VBS 5 fix the presence of at least one device using cellular communication (since a large-sized object is located inside a building made using radio-opaque fabric, cellular communication devices will be detected exclusively inside, and not outside). The information is transmitted to the control computer 6 and is the basis for further search activities. After the survey, building 2 can be dismantled until the next use.

The technical result of using the proposed invention is to provide the possibility of examining large-sized items, including those that cannot be moved to another place - stationary objects. As an example of using the proposed device for detecting radio emission sources as a large-sized object of examination, Fig. 1 shows an economic structure that cannot be moved to another place, which will serve the purpose of increasing the safety of the population.

Also, this device can be used for the simultaneous examination of several small objects. Then these items are moved under a temporary building.

It is possible with the help of the claimed device to conduct a study for the presence of radio emission sources using cellular communications, one or several people at once. The investigated persons must also be moved to the inside of the temporary structure. The research itself is carried out similarly to the above.
