RU53023U1 - DETECTOR OF FERROMAGNETIC OBJECTS - Google Patents

Abstract

The utility model relates to the field of detection of conductive objects and can be used as a stationary technical means of combating terrorism to accelerate the detection of firearms and cold steel disguised as clothes or in baggage. The technical result of the utility model is the ability to detect a ferromagnetic search object regardless of whether it is in a dynamic or static state, fixing the appearance of an individual who is a carrier of ferromagnetic mass exceeding the established one, reducing the deployment time and increasing the secrecy of installation, providing the ability to transfer data to a hard computer drive disk.

The detector of ferromagnetic objects contains a data collection and transmission unit and an autonomous indicator device. The information collection and transmission unit includes the Earth's magnetic field distortion sensors in the form of a line of magnetoresistors mounted on one axis, a television camera, a controller, a transmitter and receiver, and a body made of non-magnetic material. A stand-alone indicator device, including a housing made of non-magnetic material, a transceiver and an interface unit with an electronic computer.

A novelty in the detector of ferromagnetic objects is the use of a line of magnetoresistors as magnetic field sensors and a breakdown of the device itself into an information collection and transmission unit and an autonomous indicator device made in cases made of non-magnetic materials, while a controller and a television camera are introduced into the information collection and transmission unit , transceiver, and stand-alone indicator device

includes a transceiver and a unit for interfacing with an electronic computer.

Description

The utility model relates to the field of detection of conductive objects and can be used as a stationary technical means of combating terrorism to accelerate the detection of firearms and cold steel, grenades disguised as clothes or in baggage.

Known stationary inspection metal detector, working on the eddy current principle of detection and designed to search for metal objects. [one]

The disadvantages of such a metal detector are:

- a large number of false positives, due to the reaction to any metal objects (watches, jewelry, etc.), which significantly reduces the speed of the search;

- limited possibilities for the organization of the control zone associated with the need to install elements of conductor communication between the sensitive elements and the indicator device;

- the lack of the ability to transfer data to the hard drive of an electronic computer.

A known detector of ferromagnetic objects [2], providing a search for ferromagnetic objects of artificial origin in and near structures and having increased search security and high detection speed.

The disadvantages of this device are:

- the absence of a signal when the ferromagnetic search object is stationary;

- low range;

- lack of ability to transfer data to the hard drive

electronic computer.

The technical result of the utility model is the ability to detect a ferromagnetic search object regardless of whether it is in a dynamic or static state, fixing the appearance of an individual who is a carrier of ferromagnetic mass exceeding the established one, reducing the deployment time and increasing the secrecy of installation, providing the ability to transfer data to a hard computer drive disk.

The technical result achieved is achieved by using ferromagnetic objects in the detector as sensors of a line of magnetoresistors that perform dynamic scanning, as well as by incorporating a controller, a television camera, a transceiver device and a stand-alone indicator device, including a transceiver device and an electronic computing unit by car.

The drawing shows a structural diagram of a detector of ferromagnetic objects.

The detector of ferromagnetic objects contains a data collection and transmission unit (1) and an autonomous indicator device (2). The information collection and transmission unit includes the Earth's magnetic field distortion sensors in the form of a line of magnetoresistors mounted on one axis (3), a television camera (4), a controller (5), a transceiver (6), a body made of non-magnetic material (7 ) A stand-alone indicator device, including a housing made of non-magnetic material (8), a transceiver (9) and an interface unit (10) with an electronic computer (11).

The detector of ferromagnetic objects operates as follows.

A ferromagnetic search object (12), falling into the detection zone, distorts the lines of force of the Earth’s magnetic field. This distortion is fixed by magnetoresistors (3), about which a signal is sent to the controller (5); when the distortion is exceeded above the established norm, the controller (5) receives a command to the television camera (4) to capture the image, from where the image of the appearance of an individual carrying a ferromagnetic mass exceeding the established value comes to the controller (5). Using transceivers (6), (9), information through the interface unit (10) is sent to an electronic computer (11), where the processing, visualization and (or) scoring of the results takes place.
