Abstract

The invention relates to a device for controlling the passage of people with a passage lock, the exit of which is closed by an exit door (gate). This exit door (5) opens in response to a signal from at least one biometric unit (8) arranged in the lock area (3), with which the biometric features of a person desiring to enter can be recorded, and this biometric unit (8) is frontally opposite the entrance to the lock room (3) and preferably integrated into the exit door (5) of the lock room (3). A person entering the lock area (3) is thus almost inevitably immediately in the correct position for the detection by the biometric unit (8), i.e. frontally opposite the biometric unit.

Description

The invention relates to a device for controlling the passage of people with a passage lock, the exit of which is closed by an exit door (gate) which opens in response to a signal from at least one biometric unit arranged in the lock space for detecting biometric features of a person requesting passage .

Passage controls, such as those used for security reasons at various facilities, e.g. access to certain buildings, when crossing borders, at airports and other public and private or business and industrial facilities, are intended to help prevent unauthorized persons from gaining access to the relevant facility Provide terrain or buildings. In the simplest case, they consist of a gate that opens and clears the passage after a person has inserted an authorization certificate, e.g. their ticket, at a control machine or is identified on a reader using their ID card or (travel) passport could.

Authorization certificates, ID cards or passports and the like can be forged or passed on without authorization. Devices in which the person not only has an ID card or passport read, but also has to leave a fingerprint, which is then compared and thus a more secure identification, should ensure more security allowed so that the passage can be released - or not. Taking fingerprints, especially from a large number of people in a row at one and the same place, is met with reservations for hygienic reasons. In addition, it had to be recognized that the fingerprint of not everyone in the world is sufficiently reliable for secure identification.

Devices have therefore been proposed in which a person, after reading an ID card or passport, is initially given access through a first gate into a lock, in which they can use biometric unit (s), e.g. face recognition or other biometric recognition features , is identified, after which the exit of the lock or further access through a second gate (gate) is made possible - or not.

In known pedestrian barriers with face recognition, the biometric units, e.g. camera (s),. arranged in the side walls of the lock, and instructions must be given to the person who has entered the lock to take a certain position and posture so that the detection can be carried out reliably. These instructions must first be understood and then properly followed, so that there are always delays in the passage control, which is particularly disadvantageous in busy passages, which are often passed by people who are not familiar with such a system affects. This can also lead to incorrect rejection of people, for example if the person has not taken the correct position exactly or for too short a time.

Certain dimensions are specified for devices for checking people through, for example at airports; so is the length the devices, also known as passage barriers, are limited, for example, to 2.5 meters, and the width is also specified. For this reason, among other things, a so-called corner solution could not be used, in which the lock passage should be angled by approx. 45 ° at a certain distance from the entrance gate and the camera, e.g. for face recognition, on the angled wall of the lock passage the person first approaches, should be installed. If several locks are to be arranged side by side for passage control, they have to be offset by a certain amount in the longitudinal direction in this corner solution, which increases the space requirement and mandatory predetermined dimensions cannot be adhered to.

The object of the invention is to create a device for personal passage control with biometric recognition, for example face recognition, which adheres to the specified dimensions and in which the recognition can take place without delays, in a short time and reliably, ie also the error rate, such as a false rejection a person, must be kept as low as possible, best avoided entirely.

This is achieved according to the invention with a device according to claim 1.

By arranging the biometric unit frontally opposite the entrance to the lock room, it is achieved that a person is inevitably in the correct position when entering the lock room in front of the biometric unit, without instructions relating to this being given to the person and being followed by the person Need to become. This arrangement of the biometric unit frontally opposite the entrance to the lock room means that several through locks can be parallel to each other be arranged without increasing the space requirement in the longitudinal direction of the locks; the length of the locks remains the same over the entire arrangement of several locks, so that the above-mentioned dimensional specifications can be safely adhered to.

The exit door of the lock chamber preferably consists of at least one pivoting wing known per se and the biometric unit is integrated into this at least one pivoting wing. Here, too, after entering the lock area, the person is practically inevitably in the correct position and posture in relation to the biometric unit. When the pivoting wing is pivoted into the position freeing the passage, the optical unit is pivoted out of the passage and the field of vision of the person and the person can quickly leave the lock area; it is also not tempted to continue to observe the biometric unit. Unnecessary delays are avoided.

The biometric unit preferably consists of a recording device, for example a camera, for recording and recognizing biometric features, for example the face and / or the iris, of a person desiring to enter, and a display is provided for the image recorded by the recording device; the receiving device and the display are integrated in the pivoting wing of the exit door of the lock room; the receiving device can form a unit with the display. On the display, the person can observe and follow the recognition process, and by doing this involuntarily, he inevitably maintains the correct position and posture in relation to the recording device (camera). After the exit door has been swung open, the recording device and the display are out of the person's field of vision, they are not misled, to keep looking at the display, but will leave the lock area quickly and without unnecessary delay.

Lighting means for uniform, low-glare, low-cast shadow and low-reflection illumination of the face of the person concerned are advantageously arranged in the lock space; This way, reflections on glasses can be minimized.

The lighting means can advantageously also be integrated into the pivoting wing of the exit door above and / or below and / or next to the recording device (camera). But they can also be arranged laterally in the lock space.

The lighting means can be adjustable and / or controllable as required.

In order to direct the attention of the person in the lock area in the right direction, a device for generating sound, e.g. a loudspeaker, for generating short, broadband noises such as cracking or clicking, can also be arranged close to the biometric unit. This can also ensure that the person takes the required position.

According to a preferred embodiment of the invention, access to the lock space is blocked by an entrance door which opens upon a signal from a control unit arranged in the entrance area for a person's access authorization. This control unit can be a device for capturing the alleged identity, in particular on the basis of authorization certificates or ID cards or passports, or a device for capturing a PIN be. A preliminary check can be carried out before a person enters the lock area and this can be compared with the subsequent biometric recognition. This increases the overall reliability of the control.

A display unit, e.g. a monitor, on which the reading process can be followed, can also be assigned to the device for recording the identity in the entrance area.

A simple biometric system, e.g. a fingerprint scanner, can also be installed in front of or on the entrance door to verify access to the lock.

It is particularly advantageous if the biometric unit for detecting biometric features, in particular biometric features of the face and / or the iris, of a person desiring the passage is vertically displaceable for its exact positioning in relation to the person concerned. For this purpose, a device for detecting the body height of the person can be arranged at the entrance to the lock area, followed by an electronic unit for generating a control signal for the vertical displacement unit of the biometric unit that is dependent on the determined body height. The biometric unit, preferably a camera with or without a display, can be brought into the correct position, namely at eye level, as soon as the person enters the lock area. The detection can thus be carried out on people of different body sizes with the same accuracy and in the same quality, false rejections of people are avoided, and the entire process is accelerated.

The moving unit for the vertical displacement of the biometric unit advantageously consists of a linear drive.

The device for detecting the height of the body of a person desiring the passage can consist of a light curtain, which is followed by an electronic unit for generating a control signal for the vertical moving unit, e.g. a linear drive, of the biometric unit, which is dependent on this height of the body.

The light curtain can consist of a number of light barriers arranged one above the other and transversely to the direction of access. The height of the person can be determined from the highest light barrier, which is interrupted when the person enters.

The distance between the individual light barriers can be 2.5 cm. This is considered sufficient to determine the height of a person with the necessary accuracy.

According to a useful further development of the invention, several light barriers are integrated in the base of the device at a short distance from the floor of the lock space over its length. In this way, the position of a person in the lock room can be reliably determined and it can be recognized whether any objects, e.g. suspicious pieces of luggage, have been left in the lock room after leaving the lock room. This means that security requirements can be met.

About halfway up the lock area, several light barriers can be integrated into the side walls over its length be. In this way it can be seen whether, for example, there are several people in the lock area at the same time, and what is known as tail-gating, i.e. trying to get another person through, perhaps undetected, can be avoided. The position of a person can thus be recognized even more reliably and, for example, if the camera is approached too closely, a signal can be generated to correct the position accordingly.

In order to further increase security, recording devices for monitoring can be installed on the frame and / or on the pillars of the lock chamber.

The invention is described in more detail below with reference to the accompanying drawings; show it:

Fig. 1 FIG. 4 shows a two-line device for controlling people's passage, whereby two-line means that two the same passage locks are arranged in parallel next to one another. An extension to a three- or four-line device, for example, is just as conceivable as the construction of a single-line device. The side walls 2 of the lock rooms 3 are fixedly mounted on bases 1. A person gains access to a lock room 3 through an entrance door 4, which in the embodiment shown consists of a two-wing, front pivoting door 4 and which only reacts to a signal from an electronic unit opens. The person can leave the lock chamber 3 through an exit door 5, in the embodiment shown a single-leaf swing door 5, which opens in response to a signal from a further electronic unit. In front of one side wall 2 or on a gate frame 11 of each passage lock, a device 6 for detecting the alleged identity, for example a reader 6, is attached above the base 1 and firmly connected to it Has to enter passport and via which a signal is generated in an electronic unit, a computer, upon which the entrance door 4 opens. A monitor 7 can preferably be attached above the reading device 6, on which the reading-in process on the reading device 6 can be observed and followed and with the aid of which a person can also be instructed and assisted in operation. A simple, first biometric system, for example a fingerprint scanner, can also be mounted in front of or on the entrance door 4 in order to verify the access to the lock area 3 as securely as possible. A camera 8, preferably with display 9, for biometric recognition, e.g. face recognition, recognition of the face as a whole and / or the iris of a person who has entered the lock room 3, is integrated as a biometric unit in the pivoting wing 5 of the exit door 5. The camera 8 and display 9 are therefore arranged frontally opposite the entrance of the lock chamber 3, see above that a person entering necessarily and without special instructions assumes the required and correct, namely frontal position to the camera 8. The display 9 will have the effect that the person concerned will follow the process of image recording for the biometric recognition on the display 9, i.e. remain in the required position and not be distracted, for example turning their head, which would have to lead to an interruption of the process . In order to attract the attention of the person and thus the frontal alignment on the camera 8, a device for generating sound, e.g. a loudspeaker, can be arranged spatially close to the camera 8, which generates short, broadband noises (e.g. cracking, clicking) can be located by humans and thus directs a person's attention in the right direction. The display 9 shows the mirrored image of the person spatially close to the camera 8, so that the person receives information about their positioning and can intuitively correct any incorrect positions. Preferably also integrated in the swivel wing 5 of the exit door 5, above and below the camera 8 and the display 9, lighting means 10 are arranged so that a uniform, low-glare, low-shadow, low-reflection illumination of the face of a person is achieved in order to meet the requirements to be able to receive compliant photographs. But it is also possible to arrange the lighting means laterally if necessary. The lighting means 10 can be adjustable.

A recorded with the camera 8 or another suitable recording device, possibly among several as the best selected image that is visible on the display 9, is evaluated in an electronic unit, such as a programmable computer, and a signal is generated therefrom, which is sent to a control unit is forwarded, Via which the swivel leaf 5 of the exit door 5 is opened or, if the worst comes to the worst, is also held in the closed position if a certain person is not supposed to pass. When the swivel wing 5 is swung open, the camera 8 and the display 9 are also swiveled out of the person's field of vision, so that they are not tempted to continue to observe the display 9, but rather to leave the lock chamber 3 quickly. The arrangement of the camera 8 with display 9 in the swivel wing 5 of the exit door 5 also avoids unnecessary delays in the passage control and speeds up the process, which is particularly advantageous in the case of heavily frequented pass-through locks, e.g. at airports.

The pivoting wing 5 of the exit door 5 is located between columns 12 and is pivotably mounted on one of the columns 12. The necessary electronic units, computers and control units can be accommodated in the columns 12 in an advantageous and space-saving manner with all accessories.

In order to obtain images suitable for biometric face recognition, the recording device or camera 8 should be located as close as possible to eye level with the person to be recorded, which naturally depends on the body size of a person and varies greatly from person to person. In order to bring the camera 8 to eye level, it can be adjusted in the vertical direction together with the display 9 with the aid of a fast linear drive. The linear drive receives its command from an optical sensor, which determines the height of a person when entering the lock space 3. For this purpose, a light curtain, for example, is installed at the entrance of the passage lock, which consists of a number of light barriers arranged one above the other and transversely to the passage direction. From the at the highest light barrier, which is interrupted when entering the lock area, the height of the person can be determined. The distance between the individual light barriers can be, for example, 2.5 cm. This is considered sufficient to be able to determine the height of the body with the accuracy required for the purpose. The measurement signal of the light curtain serves as a control variable for the linear drive, which moves the unit consisting of camera 8 and display 9 into position at eye level; then a fine adjustment of the camera position can be made by processing the camera image. The camera 8 is therefore already correctly positioned when the person has entered the camera field of view. The overall process of the process is thus accelerated again.

According to a useful further development of the invention, several light barriers can be integrated in the base 1 of the lock chamber 3 over its length and at a short distance from the floor. In this way, the position of a person in the lock room 3 can be reliably recognized and it can be seen whether any objects, e.g. suspicious pieces of luggage, may have been left behind in the lock room 3 after leaving the lock room 3; a so-called clear gate can be carried out, which meets the security requirements.

In addition, several light barriers can be integrated about halfway up the lock space 3 over its length in the side walls 2, which allow it to be recognized whether, for example, several people are in the lock space 3 at the same time. In this way, so-called tail-gating, i.e. the attempt to smuggle another person through undetected, can be prevented. The position of a person can thus be recognized even more precisely and, for example, if it is too close Approach the camera to generate a corresponding signal to correct the position.

To further increase security, 3 surveillance cameras can be installed on the frame 11 and / or on the pillars 12 of the lock space.
