Description

The utility model relates to reconnaissance and alarm systems and alarm systems, and can be used on large areas for monitoring and guarding the perimeter of large territories, and for automatic remote detection and observation of the movement of people, equipment, and other purposes. It can mainly be used to protect the border.

A device for detecting an intruder is known that contains a television camera (see RF patent No. 7225 with priority of 10/15/1997 for the utility model "Device for detecting an intruder"). The disadvantage of this device of the utility model is the presence of only one detection channel.

It is also known a device for detecting an intruder containing at least one pair of video cameras (see the application for the grant of a patent of the Russian Federation for invention No. 2003115358 with a priority of May 26, 2003 “Method for detecting an intruder and a device for its implementation”). The disadvantage of this device is the strong dependence of the probability of detecting an intruder on the time of day and weather conditions.

Also known is a stationary monitoring system manufactured by EVP Defense under the brand name MIRA (see http://www.evpudefence.com/en/products/stationary-monitoring-systems/mira), which contains an infrared camera, a television camera, and a rotary device. This monitoring system is designed to monitor territories and detect moving objects. The disadvantage of this system is the lack of a low-level camera in the system, which allows you to observe when changing the time of day without active backlighting, the lack of exact conjugation of the optical axes of the camera and the thermal imager, uneven load distribution on the slewing ring, which leads to a reduction in the life of the slewing ring .

The closest analogue (prototype) is a monitoring system based on the Focus-D long-range optical-electronic module (see http://www.favorit2003.ru/focus.html) including an infrared camera (thermal imager), video camera, rotary device, workstation (AWS).

The main disadvantage of this system is essentially the separate (at different times of the day) operation of the thermal imager and video camera: the video camera is designed to work in the daytime, the thermal imager is designed to work at night, which dramatically reduces the efficiency of the system. It is not possible to simultaneously monitor from two video channels. The disadvantage of this system is the use of a television camera with a low sensitivity value, which leads to the forced use of a cooled thermal imaging camera (as part of the product) with a small service life in low light conditions - dusk and dawn.

The technical problem, which is solved by the claimed device, is to provide a high probability of detection and recognition of objects at long ranges within optical visibility regardless of the time of day.

The device comprises a video unit integrating a color television camera with a motorized varifocal lens, a black and white high-sensitivity television camera with a mirror-lens lens, a long-wavelength infrared imaging camera of 8-12 μm with a variable field of view. The automated workstation has a video block control function (television cameras and a thermal imager) and a slewing ring, with a function for recording and storing information and with a function for displaying information.

The optoelectronic module is a multisensor system. The device implements a three-channel system for day and night observation of objects in the visible and infrared wavelength spectrum. The device allows you to monitor territories by detecting and recognizing moving and stationary targets of any class; automatically accompanies targets, panes the observed terrain in the 360 ° sector, is able to work on preset points (the preset point means the azimuth and elevation angle of the most important objects for observation previously saved by the operator, the operator can switch to the preset point at any time), has automatic scanning of a given sector. Integration with other distributed systems for the protection of territories can significantly increase the efficiency of the device.

Figure 1 shows a block diagram of a device, where:

1 - video block;

2 - color television camera with a motorized zoom lens;

3 - infrared thermal imaging camera 8-12 microns with a variable field of view;

4 - black and white television camera high sensitivity with a mirror-lens lens;

5 - slewing ring;

6 - electrical cabinet;

7 - AWP;

8 - integration unit.

The device operates as follows.

According to a given program with AWP 7 and / or under the control of the operator, the video block 1 located on the slewing rotary device 5, controlled with AWP 7, scans the monitoring area. Information recorded by a color television camera with a motorized varifocal lens 2, a black-and-white high-sensitivity television camera 4 and a thermal imaging camera with a working range of 8-12 μm 3 is fed to the workstation 7. Integration of three surveillance channels allows monitoring at any time of the day. A thermal imaging channel operating in the infrared spectrum of wavelengths of 8-12 microns provides the best detection range in fog and poor visibility conditions. The rotary support device 5 provides scanning of the territory in the range of angles in azimuth - circular (n · 360) °; and in elevation ± 35 °.

Workstation 7 has a built-in integration unit 8 with distributed security systems of any difficulty level. The integration unit 8 carries out target recognition, its auto-capture and subsequent auto-tracking, implements the functions of stabilization and correction of the video stream, recording, storage and viewing of video clips and still frames.

Upon receipt of information from any distributed security system integrated with the claimed device, the optical axis of the video block is positioned by means of a slewing ring device at the location of the violation indicated by the distributed security system. Positioning occurs both automatically and automation under the control of the operator. The power supply of the device is carried out by means of a control cabinet 6, which is connected to the rotary support device 5, video block 1. The power supply of the AWP 7 is carried out from an alternating current network with voltage of 220 V ± 10%, frequency (50.0 ± 0.5) Hz.

The device is industrially applicable.

As constructive elements, appropriate devices supplied by the industry can be used, such as black-and-white and color television cameras, IR cameras for video unit 1, computers and displays equipped with specialized software that implements integration, auto-capture and auto-tracking functions for AWP 7, video stream stabilization.
