Description

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

Passage control, as used in a wide variety of facilities, e.g. When accessing certain buildings, when crossing borders, at airports and other public, private or business and industrial facilities for security reasons, the aim is to help prevent unauthorized persons from gaining access to the site or building in question. In the simplest case, they consist of a gate or gate that only opens and opens the passage after a person has issued an authorization certificate, e.g. introduced their ticket, or could be identified on a reader using their ID or (passport) passport.

Credentials, ID cards or passports and the like can be forged or passed on without permission. Devices are to provide more security, in which the person not only has to have an ID or passport read, but also has to leave a fingerprint, which then makes a comparison and thus a more secure one Identification allowed so that the passage can be released - or not. The taking of fingerprints, especially from a large number of people in succession at one and the same place, is met with reservations for hygienic reasons. In addition, one had to recognize that the fingerprint of every person worldwide is not sufficiently reliable for reliable identification.

Devices have therefore been proposed in which, after reading in an identification card or passport, a person is first given access to a lock through a first gate, in which they can be accessed using biometric unit (s), e.g. facial recognition or other biometric identification features, after which it is possible to leave the lock or further access through a second gate (or not).

In known face locks with face recognition, the biometric units, for example camera (s), are arranged in the side walls of the lock, and instructions must be given to the person who has entered the lock to take a specific position and posture the detection can be carried out reliably. These instructions must first be understood and then followed correctly, so that there are always delays in the passage control, which is disadvantageous especially in the case of heavily frequented passages, which are often also used by people who are not familiar with such a system affects. This can also lead to false rejections by 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 the passage of people, for example at airports; for example, the length of the devices, also known as passage barriers, is limited 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 at a certain distance from the entrance gate by approx. 45 ° and the camera, e.g. for facial recognition, on the angled wall of the lock passage the person approaches first, should be installed. If several locks for passage control are to be arranged next to each other, they have to be offset by a certain amount in the longitudinal direction with this corner solution, which increases the space requirement and the prescribed dimensions cannot be maintained. Through the WO 99/06928 a device for passage control is known in which the lock passage is angled at a distance from the entrance gate of approximately 45 °; this creates a first passage section and a second passage section. A biometric sensor, also called a biometric unit, is located on the angled side wall of the second passage section of the lock passage. If several locks are arranged side by side, this increases the space requirement, which makes it difficult to comply with the prescribed dimensions. More importantly, a person entering the lock passage is not immediately and inevitably in the correct position for detection by the biometric sensor. A person approaching the biometric sensor through the first passage section must turn his head towards the biometric sensor. A person will not do this on his own, but must be instructed position and posture, so that the detection by the biometric sensor can be carried out reliably. As already mentioned in another context above, this repeatedly leads to delays in the passage control, which has a disadvantageous effect especially in the case of heavily frequented passages, which are also passed by people who are not familiar with such a system. This can lead to false rejections by people, for example if the person has not taken the required position exactly or for a short period of time.

The object of the invention is to provide a device for controlling the passage of people with biometric recognition, e.g. To create face recognition that complies with the specified dimensions and in which the recognition can be carried out quickly and reliably without delays, i.e. The error rate, such as a false rejection of a person, must also be kept as low as possible, ideally avoided entirely.

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

By placing the biometric unit frontally opposite the entrance to the lock room, it is achieved that a person is inevitably in the correct position frontally in front of the biometric unit when entering the lock room, without instructions being given to the person and followed by the person Need to become. This arrangement of the biometric unit frontally opposite the entrance to the lock room also allows several through-locks can be arranged in parallel next to each other without increasing the space required in the longitudinal direction of the locks; the length of the locks remains the same across the entire arrangement of several locks, so that the above-mentioned dimensions can be safely met.

By designing the exit door of the lock room from at least one swivel wing known per se and the integration of the biometric unit in the at least one swivel wing, the person is practically inevitably in the correct position and attitude to the biometric unit after entering the lock room. When the swivel wing is swiveled into the position that clears the passage, the optical unit is swiveled out of the passage and the field of vision of the person and the person can quickly leave the lock area; it is not tempted to continue to observe the biometric unit. Unnecessary delays are avoided.

The biometric unit 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 passage, and a display is provided for the image recorded by the recording device; the cradle and the display are integrated in the swivel wing of the exit door of the lock room; the recording device can form a unit with the display. On the display, the person can observe and track the recognition process, and by doing so involuntarily, they inevitably maintain the correct position and attitude to the recording device (camera). After swinging open the exit door, the cradle and the display are outside the person's field of vision, they will not be tempted to look further at the display, but will leave the lock room quickly and without unnecessary delay.

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

The lighting means can advantageously also be integrated in the pivoting wing of the exit door above and / or below and / or next to the receiving device (camera). However, they can also be arranged laterally in the lock room.

The lighting means can be adjustable and / or adjustable if necessary.

In order to direct the person's attention in the lock room in the right direction, a device for sound generation, e.g. a loudspeaker can be arranged to generate short, broadband noises, such as clicking or clicking. It can also be achieved that the person assumes the required position.

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

A display unit, e.g. a monitor, on which the reading process can be tracked.

In front of or at the entrance door, a simple biometric system, e.g. a fingerprint scanner can be installed to verify access to the lock.

It is particularly advantageous if the biometric unit for recording biometric features, in particular biometric features of the face and / or the iris, of a person requesting passage is vertically displaceable for their exact positioning in relation to the person in question. For this purpose, a device for detecting the body height of the person can be arranged at the entrance to the lock room, which is followed by an electronic unit for generating a control signal for the vertical travel 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 thus be brought into the correct position by the person entering the lock room, namely at eye level. The detection can be carried out with the same accuracy and in people of different heights of the same quality, falsely rejecting people is avoided, and the whole process is accelerated.

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

The device for detecting the body height of a person wanting the passage can consist of a light curtain to which an electronic unit for generating a control signal for the vertical travel unit which is dependent on this body height, e.g. a linear drive that is subordinate to the biometric unit.

The light curtain can consist of a number of light barriers arranged one above the other and transversely to the direction of access. The body height can be determined from the highest arranged 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 a person's height with the required accuracy.

According to a useful 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 room along its length. The position of a person in the lock room can thus be reliably determined and it can be recognized whether any objects, for example suspicious luggage, have been left behind in the lock room after leaving the lock room were. This means that security requirements can be met.

At about half the height of the lock room, several light barriers can be integrated in the side walls along its length. This way you can see whether e.g. there are several people in the lock room at the same time, and so-called tail-gating, i.e. the attempt to pass another person through, perhaps undetected, can be avoided. The position of a person can thus be recognized even more reliably and e.g. If you approach the camera too close, a signal can be generated to correct the position accordingly.

To further increase security, monitoring devices can be installed on the frame and / or on the pillars of the lock room.

Fig. 1 shows a two-line device for personal passage control, with two-line means that two identical passage gates are arranged in parallel next to each other. An extension to a three- or four-line device, for example, is conceivable if necessary, as is the setting up of a single-line device. The side walls 2 of the lock rooms 3 are permanently mounted on bases 1. A person has access to a lock room 3 through an entrance door 4 which, in the embodiment shown, consists of a double-leaf, front swing door 4 and which only respond to a signal from an electronic unit opens. The person can leave the lock room 3 through an exit door 5, in the embodiment shown a single-leaf swing door 5 which opens upon a signal from another electronic unit. In front of the one side wall 2 or on a goal frame 11 of each passage gate, a device 6 for detecting the claimed identity, for example a reading device 6, is attached above the base 1 and firmly connected to it, into which a person has an authorization certificate, an identification card, a 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 process on the reading device 6 can be observed and tracked and with the aid of which a person can also be guided and supported in the operation. In front of or at the front door 4 can a simple, first biometric system, for example a fingerprint scanner, may also be installed in order to verify access to the lock room 3 as securely as possible. A camera 8, preferably with a display 9, is integrated in the swivel wing 5 of the exit door 5, preferably with a display 9, for the biometric recognition, for example face recognition, the recognition of the face as a whole and / or the iris, of a person who has entered the lock space 3. The camera 8 and display 9 are thus arranged frontally opposite the entrance to the lock room 3, so that an entering person inevitably and without special instructions assumes the required and correct, namely frontal position to the camera 8. The display 9 will cause the person in question to follow the process of image acquisition for the biometric recognition on the display 9, that is, to remain in the required position and not be distracted, for example turning his head, which should lead to an interruption of the process . In order to achieve the attention of the person and thus the frontal alignment to the camera 8, a device for sound generation, e.g. a loudspeaker, can be arranged spatially close to the camera 8, which generates short, broadband noises (e.g. crackling, clicking) that are locatable for humans and thus directs a person's attention in the desired, correct direction. The display 9 shows the mirrored image of the person close to the camera 8, so that the person receives information about their position and can intuitively correct any incorrect positions. Also preferably integrated in the swivel wing 5 of the exit door 5, lighting means 10 are arranged above and below the camera 8 and the display 9 such that a uniform, Low-glare, drop shadow and low-reflection lighting of the face of a person is achieved in order to be able to obtain light images that conform to the requirements. However, it is also possible to arrange the lighting means laterally if required. The lighting means 10 can be adjustable.

An image recorded with the camera 8 or another suitable recording device, possibly among several selected as best, which 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, in the event of an emergency, is also held in the closed position when 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 field of view of the person, so that the person is not tempted to continue to watch the display 9, but rather to leave the lock space 3 quickly. The arrangement of the camera 8 with the display 9 in the swivel wing 5 of the exit door 5 also ensures that unnecessary delays in the passage control of the people are avoided and the process is accelerated, which is particularly the case with heavily used passage gates, e.g. at airports, is an advantage.

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

In order to obtain images suitable for biometric facial recognition, the recording device or camera 8 should, if possible, be at eye level of the person to be recorded, which naturally depends on the height of a person and varies greatly from person to person. In order to bring the camera 8 at eye level, it can be adjusted in the vertical direction together with the display 9 using a fast linear drive. For this purpose, the linear drive receives its command from an optical sensor, which determines the body height of a person when entering the lock room 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 transverse to the passage direction. The body height of the person can be determined from the highest arranged light barrier, which is interrupted when entering the lock room. The distance between the individual light barriers can be, for example, 2.5 cm. This is considered sufficient to be able to determine the body height 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; Subsequently, the camera position can be fine-tuned 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 is accelerated again.

According to a useful development of the invention, several light barriers can be integrated in the base 1 of the lock room 3 over its length and at a short distance from the floor. The position of a person in the lock room 3 can thus be reliably recognized and it can be seen whether any objects, e.g. suspicious luggage left in lock room 3; a so-called clear gate can be implemented, which meets the security requirements.

In addition, several light barriers can be integrated in the side walls 2 at about half the height of the lock space 3, which allow to recognize whether e.g. several people are in lock room 3 at the same time. This prevents so-called tail-gating, i.e. the attempt to pass another person through undetected. The position of a person can also be recognized more precisely and e.g. If you approach the camera too close, 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 room.
