Description

The invention to signaling devices, including video cameras, designed to protect the territory, for example, a linear section of the border, and can be effectively applied to ensure security against terrorist threats.

The prior art system for protecting the border of a protected area (RU 2365857, IPC F41H 13/00, published on 08.27.2009), designed to protect the border using video surveillance. The system comprises an overview camera connected to the control computer, at least one unit of remotely controlled small arms mounted permanently. In addition, the system is equipped with motion sensors connected through the intruder detection controller to the control computer, light and sound alarm systems connected through light and sound alarm controllers to the control computer [1].

The disadvantage of the invention is the low reliability of the system under conditions of various optical interference.

The closest in technical essence to the proposed technical solution is a system for implementing the method of protecting a linear section of the border (RU 2460142, IPC G08B 13/196, published on 08.27.2012).

The system contains a computer-based information collection and processing subsystem to which video cameras are connected with backlight lasers attached to them and thermal imagers installed along a linear section of the border [2].

A disadvantage of the known technical solution is the low reliability of the system under conditions of various optical interference.

The technical problem to which the claimed invention is directed, which coincides with the technical result achieved when using it, is to increase the degree of reliability of protection of the protected territory, for example, a linear section of the border.

To solve this problem, in a protected area protection system that contains a subsystem for collecting and processing information and the associated video surveillance subsystem using cameras equipped with backlight lasers, thermal imaging surveillance subsystem using thermal imagers, moreover, thermal imagers and video cameras are installed along a linear section of the border with alternation, and also a vibration detection subsystem, the output of the information collection and processing subsystem is connected to the bi-directional interface control unit, and the aforementioned video cameras and thermal imagers are equipped with optical filters with a passband that matches the radiation frequency of the backlight lasers, in addition, the subsystem for collecting and processing information is based on a programmable microcontroller.

The invention is illustrated in the drawing, which shows a structural diagram of a protected area protection system.

The protection system of the protected area 1, along which a fence 2 is made, containing poles 3 and a mesh 4 stretched between them, contains a subsystem for collecting and processing information 5. The system also contains a video surveillance subsystem 6, which includes cameras 7 with backlight lasers 8. In addition, the system contains a subsystem of thermal imaging 9, which includes thermal imagers 10, and cameras 7 and thermal imagers 10 are equipped with optical filters 11 with a passband that matches the frequency of the radiation of the backlight lasers. In addition, the system contains a vibration detection subsystem 12 with sensitive elements 13 mounted on the grid 4. Subsystem 5 is connected to the subsystems 6, 9 and 12 via communication channels 14. The output of the information collection and processing subsystem 5 based on the programmable microcontroller is connected with a control unit 15, which is a microprocessor system, for example a personal computer, a bi-directional interface 16.

As optical filters can be used, for example, narrow-band IR filters, manufactured by Izovaki, transmitting radiation only in a certain narrow wavelength range, while absorbing longer and shorter waves [3].

The system of protection of the protected area works as follows.

Power is supplied to all subsystems: 5, 6, 9 and 12. Information from video cameras 7 and thermal imagers 10, as well as from the vibration detection subsystem 12 with sensitive elements 13, is transmitted via communication channels 14 to subsystem 5 based on a programmable microcontroller, where preliminary processing is performed information. Further, the signals from the output of the microcontroller through the interface 16 are sent to the control unit 15, where the information is analyzed and all subsystems for ensuring security in the protected area are controlled. In the normal mode of operation of the video surveillance subsystem 6 using cameras 7 with laser illumination by lasers 8 and thermal imaging 9 using thermal imagers 10, they can stably detect security threats in the daytime and at night in fog, snow, rain.

In the event of an emergency, for example, a dazzling effect in a wide spectrum of radiation on optical surveillance equipment, protective filters will significantly attenuate this harmful radiation, since they pass only a very narrow frequency range that matches the frequency of the backlight lasers 8. As a result, the system will not exit out of order and will reliably provide protection for the protected area.

Thus, the use of the system allows to increase the reliability of protection of the protected area.
