Abstract

The invention is related to the systems of so-called “security entrance” and, in particular, to the systems for preventing the entry of forbidden articles and/or substances from an unprotected area to a protected one. The simplicity, efficiency and secrecy of examination in a security system for preventing the entry of forbidden articles and/or substances from a surrounding area to a protected one, said system comprised of a partitioning separating a protected area from an unprotected one, at least, one walk-gate made in said partitioning, an information control-and-processing device and a detector of forbidden articles and/or substances is achieved due to said detector of forbidden articles and/or substances made an X-ray kind to provide secret examination of every person passing through said walk-gate.

Claims

1. A security entrance system for preventing entry of forbidden articles and/or substances from a surrounding area to a protected one comprising:

a partitioning separating a protected area from an unprotected one;

at least one walk-gate made in said partitioning;

an information control-and-processing device and a detector of forbidden articles and/or substances,

wherein said detector of forbidden articles and/or substances comprises an X-ray radiation source to provide examination of a person passing through at least one walk-gate;

wherein an X-ray receiver of said detector is made as a vertical linear X-ray receiver built-in into a walk-gate element opposite to said X-ray radiation source; and

wherein said walk-gate element with said built-in X-ray receiver is a movable door with a drive mechanism of said door made so that it maintains a predefined ratio of a door motion speed and of a scanning rate of the X-ray radiation source.

2. The security entrance system as in claim 1, wherein at least one walk-gate in said partitioning is supplied with at least one door having a respective drive mechanism connected to a signal output of the information control-and-processing device.

3. The security entrance system as in claim 1, wherein said detector of forbidden articles and/or substances is comprised of an X-ray scanning radiation source and of an X-ray receiver that is co-linear to said X-ray radiation and is connected to information inputs of the information control-and-processing device.

4. The security entrance system as in claim 3, wherein said detector of forbidden articles and/or substances further comprises a horizontal linear X-ray receiver disposed under a walk-gate floor provided with at least one X-ray transparent portion or built-in into said walk-gate floor.

5. The security entrance system as in claim 3, wherein said detector of forbidden articles and/or substances further comprises a horizontal linear X-ray receiver built-in into a walk-gate floor.

6. The security entrance system as in claim 3, wherein said detector of forbidden articles and/or substances further comprises a horizontal linear X-ray receiver disposed above a walk-gate ceiling provided with at least one X-ray transparent portion.

7. The security entrance system as in claim 3, wherein said detector of forbidden articles and/or substances further comprises a horizontal linear X-ray receiver built-in into a walk-gate ceiling.

8. The security entrance system as in claim 1, wherein said X-ray radiation source of said detector of forbidden articles and/or substances is made to generate a flat fan-shaped X-ray beam in a walk-gate plane and can be disposed behind a bottom part of one of the walk-gate side walls provided with at least one X-ray transparent portion.

9. The security entrance system as in claim 1, wherein said X-ray radiation source of said detector of forbidden articles and/or substances is made to generate a flat fan-shaped X-ray beam in a walk-gate plane and is built-in into a bottom part of one of the walk-gate side walls.

10. The security entrance system as in claim 1, wherein said walk-gate is additionally supplied with a sensor to define a presence of a person ready to pass through said walk-gate with an output of said sensor being connected to an input for activating the X-ray radiation source.
