Description

The utility model relates to equipment providing blocking of radio frequencies, which can be used, for example, for mobile communications and / or for radio-controlled devices, and can be used in information security systems, in particular, to protect mobile users from unauthorized control and to block triggering of radio-controlled devices for various purposes, installed secretly or in violation of the current legislation (including the prevention of terrorist acts).

Known, in particular, the universal blocker "Pelena-8U", which can be used both as a portable, operating with built-in antennas, and as a transportable, operating using external antennas on magnetic bases (URL: / http: // kobra .su / catalog / nosimyj / item / 174-pelena-8u /; date of treatment 09/02/2020). This device includes two transmitters mounted in cases with built-in antennas.

The closest in terms of the set of essential features - the prototype of the claimed utility model - is the Senao JA-158 cellular communication blocking device, which includes a housing, jammers and radiating antennas (URL: / https://www.cnews.ru/reviews/free/techsec2006/ articles / anticonnect.shtml; date accessed: 12/08/2020).

The general disadvantages of the above technical means include the inability to register, encrypt, store in memory and transfer information to a remote device. Such additional functionality can be used, for example, to control the mode of use of such devices (time, place of switching on, radiating frequencies, radiation power, etc.). At the same time, users of such blockers can use them for other purposes, for example, radio-controlled VU blockers can be used constantly to block communication of citizens, or vice versa, do not turn on such devices (or use not all emitting ranges) when this is required, for example, by the rules of instructions for the purpose of ensuring security.

Known mobile communication devices with additional functions (US Pat. RU 2617412, publ. 20.11.2015. Bull. No. 32). They include a case, a processor located in it, and an interface connector connected to the processor for connecting a module that provides the device with additional functions. These devices can include, in particular, a memory module, a cryptoprocessor, and a number of communication interfaces, which makes it possible to perform cryptographic operations on information, store it in memory, and transfer it to a remote device. The disadvantages include the impossibility of organizing with its help blocking frequency ranges to prevent unauthorized removal of information from a mobile phone or with its help, as well as to prevent covert activation of a radio-controlled device for other purposes.

The technical problem to be solved by the proposed utility model is to eliminate the shortcomings of the prototype - to create a device that allows not only blocking frequency ranges in which unauthorized information retrieval from a mobile device is possible, control and activation of radio-controlled devices and other functions using a radio channel, but also register and store in memory information about the modes of operation of such blockers (frequencies, time and place of activation, etc.), as well as transfer the received information to a remote device.

The solution to this technical problem is carried out by introducing a processor blocker and additional modules functionally related to it, namely, a memory module, a communication module, into the design of the blocker.

The radio frequency blocker proposed as a present useful model is illustrated by a drawing (Fig. 1) and includes a housing 1, a jamming module 2, a communication module 3, and a memory module 4.

The jamming module 2 contains a block 21 of jammers and an antenna unit 22 with radiating antennas 221. Depending on the design of the device, the number of jammers and radiating antennas 221 may be different.

Communication module 3 is designed for data transmission via wireless and wired communication and can be, but not exclusively, a Bluetooth module, a Wi-Fi module, a cellular communication module of the GSM standard (900/1800), and have a slot 31 for connecting a SIM cards and a USB port 32 with a corresponding controller 33. In this case, data transmission can be carried out using wired and wireless technologies.

Depending on the design of the device, the number of slots 31 for installing SIM-cards in the communication module 3 can be from one or more.

The memory module 4 contains a machine-readable medium 41 (may be in the form of a memory card, flash drive). The computer-readable medium 41 can be removable from the housing 1 or non-removable.

The device proposed as a present utility model operates as follows.

After turning on the device block 21 generators of interference begins to transmit interference signals of a given power. In the memory of the device, the turn-on time is recorded and recorded on a machine-readable medium 41, as well as, if necessary, other related information - operating time, radiating antennas, radiating ranges, powers, operating time, etc. For analysis (and other functions), the device a computer (or any computing device, processor) can be added. The retrieval of the information received can be carried out both through the connector and by means of removing the machine-readable medium and connecting it to the computer of the controlling person. Preferably, to prevent unauthorized access to the memory module 4, physical protection of the device body and its connectors (by means of locks, locking devices, sealing, etc.). Also, access to information stored using module 4 is preferably protected by information security methods (for example, access through entering a password, encrypting stored information, etc.).

In this case, the above information (on time of switching on, ranges, power, etc.) can be transmitted to a remote device using the communication module 3.

It should be noted that jamming module 2 can block the frequencies of communication module 3 (the emitting jamming range 2 can "overlap" the range for communication of module 3). To neutralize such a negative scenario, you can use the following possible solutions:

1) Inclusion of the so-called "transparency window" in the emitting range (that is, exclusion from the emitting frequencies of the jammer 2, the frequencies that are used for communication by the communication module 3);

2) Information transmission before jamming (for example, the choice of the information transfer algorithm through the communication module is such that after pressing the "on" button of the jammer, power is supplied to the radiating antennas only after the message is sent by the communication module 3);

3) Transfer of information immediately after turning off the jamming module.

Also, if necessary, the above-described device can be equipped with a position determination module (for example, using GPS and / or GLONASS, etc.). With the help of it, in the memory module 4 (and / or this information can be transmitted by means of the communication module to the remote device), the place (geographical location) of jamming can also be fixed. This information may be necessary, for example, to identify abuses of the blocker user (for example, permission to use the blocker was issued to the user only for a certain place, and he uses it in other places) or, conversely, according to safety standards, the user must turn on the blocker in certain places ( for example, when following a certain route in order to ensure your own safety) and there are doubts about the user's following these instructions.

If the emitting range of the jamming module 2 "covers" the range of the receiver of the position determination module, you can use the solutions given above (see the previous paragraph).

The technical result when using the proposed utility model is the ability to obtain information about the cases of switching on the device, duration of operation, radiated frequencies, power, etc. including the duration of operation of the jamming module 21. Such information may be of not only technical, but also operational interest, for example, to comply with certain regulatory requirements (legal requirements, instructions, orders).
