Description

The invention relates to a passage control system with at least one exit door, the exit door comprising a door leaf, the door leaf having an entrance side and an exit side, the door leaf being attached to a support for suspension, the door leaf comprising a transparent material, with the door leaf a camera system is arranged, the camera system having a movable unit, a housing and a drive for the movable unit, the movable unit and the drive being arranged within the housing, the housing being immovably fixed relative to the door leaf, the movable unit is movable in height direction within the housing, the movable unit comprising a portrait camera, the movable unit defining a swept area via the traverse path and the area of the movable unit in a front view, the swept area minus the area of the movable unit aren unit defines a released area, the housing having a rear side and a front side, the rear side being connected to the front of the housing via side walls.

Such a pass-through control system, for example for airports, is already out WO 2010/078856 A1 known and comprises an entrance door made of glass, an exit door made of glass and a passage therebetween. In front of the entrance door there is a reader for identification documents (eg ID cards or passports), which opens the entrance door after reading out a presented identification document, in particular an ID photo. The person to be identified then passes the open entrance door, which then closes again. She is now in the passage and stands in front of the entrance side of the still closed Exit door. A camera system is arranged on the exit side of the exit door and comprises a height-adjustable unit with a portrait camera and a screen. The height-adjustable unit is brought into the height position of the head of the person to be identified, so that the person can view his own camera recording on the screen and, if necessary, correct it on instruction. A processing unit compares the camera recording with the ID photo that has been read out and opens the exit door if it matches.

The camera system off WO 2010/078856 A1 comprises a drive which is arranged on the exit side of the exit door in the vicinity of the pivot axis and which carries the displaceable unit. The moveable unit is enclosed and, for the purpose of movability, is not attached to the door leaf, but is rigidly connected to a guide carriage on a guide rail of the drive via two arms. The disadvantage is that the movable unit and the guide carriage are relatively unprotected from the environment. In this way, dust quickly gets between the guide carriage and the guide rail in the area of the guide carriage. The unit, which can preferably be moved quickly, can also injure curious children.

It is therefore known from practice to arrange the movable unit together with the drive in a housing of the camera system. This housing protects the movable unit and the drive from the environment and comprises a front and a rear side, which are connected to one another via side walls. The housing forms a closed space which contributes significantly to the longevity of the movable unit and in particular of the sensitive drive and, at the same time, rounds off the overall picture of the exit door or the camera system.

Sometimes ID photos are out of date, so that even with optimal recording conditions (sufficient lighting, several individual photos, correct height position, etc.) and with the latest artificial intelligence or algorithms, the camera recording cannot be assigned to the ID photo. For this reason, border officials are often stationed behind the transit controls, who carry out a manual check if necessary. Another job of the border guards is to monitor the area of the transit controls. The disadvantage of these known systems from practice is that the border guards do not have an unobstructed view of the passage because the housing, which is quite large due to its movability, blocks the view into the passage. The invention is therefore based on the object of providing the border guards with better surveillance of the passages.

This object or these objects are achieved by a passage control system with at least one exit door, the exit door comprising a door leaf, the door leaf having an entry side and an exit side, the door leaf being attached to a support for suspension, the door leaf being a transparent one Material comprises, wherein a camera system is arranged on the door leaf, the camera system having a movable unit, a housing and a drive for the movable unit, the movable unit and the drive being arranged within the housing, the housing being immovable relative to the door leaf is fixed, wherein the movable unit can be moved in the vertical direction within the housing, the movable unit comprising a portrait camera, the movable unit defining a swept area via the traverse path and the area of the movable unit in a front view, the swept area He minus the area of the movable unit determines a released area, the housing has a rear side and a front side, the rear side being connected to the front of the housing via side walls,
characterized in that
the back of the housing is transparent over at least a portion of the swept area.

The invention is initially based on the knowledge that there are a large number of possibilities for improving the monitoring of the passage. For example, it is possible to position several surveillance cameras at different points in the passage. In principle, this enables significantly better surveillance, which also does not require any border officials on site. However, it was found that this type of surveillance is tiring for the border guards and provokes negligence as a result. It was also found that this type of monitoring is too complex for artificial intelligence, so that this type of monitoring does not appear to be possible in the foreseeable future.

Another possibility for better monitoring of the passages is to arrange the camera system not on the exit door but on the side walls of the passageway so that the glass exit door ensures a clear view of the passage for the border guards. However, this has the disadvantage that the people to be identified do not instinctively run towards the exit door and stop in front of it, but have to be directed to the camera system on the side wall. The steering can be done optically and / or acoustically, for example. However, it has been found that this causes delays in the process, so that the throughput is noticeably reduced.

In particular, it was found that an at least partially transparent camera system provides such an insight into the area of the passage that border officials stationed behind the passage control consider this to be sufficient for their work. The border guards can perceive and interpret all essential movements of the persons to be identified. This type of surveillance is significantly less tiring for border officials and at the same time enables a high throughput of people to be identified. As a result, the object mentioned at the beginning is achieved in a particularly satisfactory manner.

The aforementioned object is also achieved by a passage control system with at least one exit door, the exit door comprising a door leaf, the door leaf having an entrance side and an exit side, the door leaf being attached to a support for suspension, the door leaf comprising a transparent material A camera system being arranged on the door leaf, the camera system having a movable unit, a housing and a drive for the movable unit, the movable unit and the drive being arranged within the housing, the housing being fixed immovably relative to the door leaf , wherein the movable unit can be moved in the vertical direction within the housing, wherein the movable unit comprises a portrait camera, the movable unit defining a swept area in a front view via the displacement path and the area of the movable unit, the swept area abz Usually the surface of the movable unit defines a released surface, the housing having a rear side and a front side, the rear side being connected to the front side of the housing via side walls.

The term “transparent” preferably means a clear material without perceptible scattering, so that a viewer can preferably see a sharp image when looking through the transparent material. Transparent materials are, for example, glasses for window panes or acrylic glass (polymethyl methacrylate, PMMA). The expression “transparent materials” also includes, in particular, safety glasses or polycarbonates. It is preferred that opaque materials be excluded from the term "transparent materials". More preferably, highly scattering materials are also not included in the expression “transparent materials”.

In Fig. 3 the camera system 5 is shown without a door leaf 2, so that the threads of the fixation 33 in the housing 7 can be seen. The housing 7 has a view of the side view of Fig. 3 in addition to the side wall 13a, a rear side 11 and a front side 12, the front side 12 of this exemplary embodiment comprising a transparent opening 39. In the side view after Fig. 3 a preferred thickened area 40 of the side wall 13a can also be seen, which has a cable opening 41 in a lower section, for example.

The transparent opening 39 from the front view according to Fig. 3 is preferably designed as a hole which is covered by the transparent material of the door leaf 2. The transparent opening 39 is preferably designed in such a way that it corresponds or essentially corresponds to a swept area of the displaceable unit 6. The swept area minus the area of the movable unit 6 in a front view results in a released area 10 through which, in this exemplary embodiment, both the person to be identified and people can look through from the exit side.

In Fig. 4 A rear view of the camera system 5 is shown, a rear side plate 43 having been omitted in this figure in order to reveal the inner workings of the camera system 5. The inner workings are primarily a drive 8 which ensures that the movable unit 6 can be moved. The drive 8 comprises in particular an electric motor 20 in the form of a stepping motor with a brake, a guide rail 16 with a toothed belt 46, a support rail 19 and a guide carriage 17 on the Guide rail 16. Further components of the drive, not shown here, can be, for example, a motor control or a DC voltage supply.

The electric motor 20 of this exemplary embodiment may draw a rated current of 4 A and exert a holding torque of 3.5 Nm, while the step angle can be 1.8 °. The electric motor 20 drives the toothed belt 46, which is arranged circumferentially in the vertical direction and to which the guide carriage 17 is connected. The guide carriage 17, for its part, is connected to the displaceable unit 6, which in this exemplary embodiment also has a cable cover 38. The cable cover 38 is preferably also connected to the support rail 19, so that the movable unit 6 is mounted on both sides on rails 16, 19, which gives additional stability.

In this exemplary embodiment, cables for a 24 V voltage supply, an RS485 bus, a CAN bus, an Ethernet cable and a grounding cable are located in the cable cover 38. The cables are expediently guided from the screen 14 or the chambers 9, 42 through the cable cover 38 to a drag chain 18. In Fig. 4 it can be seen that the drag chain 18 takes up a certain space to the side of the guide rail 16, so that the thickened area 40 is formed. The drag chain 18 ensures a minimum radius for cable bends, so that the cables are protected. The cables are guided downward within the drag chain 18 to a preferred upper transfer point 47 of the drag chain 18 and from there in a statically fixed manner.

Further components of the drive 8 are preferably located within the side wall 13c and more preferably below the electric motor 20, for example the motor control or the 24 V DC voltage supply. Some of the cables are conveniently inserted through the cable opening 41 in Fig. 4 led to the outside, below them the grounding cable, at least one cable for the power supply, and the Ethernet cable. The latter preferably transmits the portrait photos taken to a computing unit of the pass-through control system or the control system or a higher-level server. Finally, a lighting control 37, which is connected to the lighting device 22, is also arranged in a lower area.

In Fig. 5 the rear view of the camera system 5 is shown, although this differs from FIG Fig. 4 the back plate 43 covers the drive 8 entirely. The rear panel 43 has a window opening 44 which, in this exemplary embodiment, consists of a transparent plastic, for example polycarbonate. The dimensions of the window opening 44 of the rear side plate 43 correspond to the transparent opening 39 of the front side. In this way, the camera system 5 ensures transparency both when looking into the passage 36 and when looking out of it. This creates less of the feeling of being locked in for the people to be identified. In particular, however, border officials on the exit side of the exit door 1 have a better view of the passage 36 and can, if necessary, better observe the people to be identified there and better interpret their actions.

The operation of the passage control system is as follows: A person to be identified, for example a passenger in an airport building, approaches the passage control system. The display 26 signals with a green field that the person has entered the passage control system can enter. The person approaches the reader, recognizes the intuitively displayed instruction on the screen 24 of the reader 23 and then places their identification document on the scanner 25. The data from the identification document are read out and transferred to a processing unit. The entrance door 15 then opens inwards so that the person can enter the passage 36.

The entrance door 15 then closes again and the person is monitored by the surveillance camera 30. Due to the structure of the passage control system, in particular due to the exit door 1, which can be intuitively recognized as an exit door, the person approaches the exit door 1. In this exemplary embodiment, the opening of the entrance door 15 also activates a face recognition of the camera system 5, which is based on the recordings of the live image camera 42 falls back. Since faces can already be recognized as faces from a distance of several meters, the camera system 5 of this exemplary embodiment strives to keep the face of the approaching person always approximately in the center of the recording area of the live image camera 42. As a result, the displaceable unit 6 adapts its height position to the body size of the person to be identified with each step of the approaching person. As a result, the movable unit 6 moves more calmly and evenly, so that it does not have to move quickly only when the person is standing directly in front of the exit door 1.

It is very preferred that the screen 14 of the camera system 5 shows that the person is induced to move until their face is centered in the recording area of the live image camera 42 or the portrait camera 9. This can be done, for example, in that the screen 14 displays markings within which the person's face must be located. For this purpose, the live image from the live image camera 42 is displayed on the screen 14 so that the person feels as if they are facing a mirror.

In this exemplary embodiment, the camera system 5 also uses the live image camera 42 to determine whether the face of the person to be identified is sufficiently illuminated. For this purpose, images from the live image camera 42 are transferred to the lighting control 37, which checks whether stronger or weaker lighting is required. A corresponding signal is then output to the lighting device 22 in order to adapt the lighting. As soon as the camera system 5 or the lighting control 37 registers the correct illuminance in addition to the correct position of the face, a trigger signal is output to the portrait camera 9, which then takes a portrait of the person to be identified. The portrait camera 9 has a relatively high resolution which, for example, allows portraits to be taken at 13 MP. In contrast, the resolution of the live image camera may only be 2 MP.

The portrait photograph is then preferably transmitted to the computing unit via the Ethernet cable or compared with the read image of the identification document. This comparison may be carried out, for example, via an artificial intelligence in the form of a neural network. If the read out portrait of the person to be identified matches the portrait taken by the portrait camera 9, the exit door 1 opens by an electric motor actuating the pivot axis 32 and the door leaf 2 together with the camera system 5 being pivoted outward.

Optionally, before or after the portrait takes place, but in any case before the exit door 1 is opened, the instruction can be output on the screen 14 that the person should use his hand or a finger the hand should place on the sensor 35 for hand biometrics. The fingerprint or handprint determined in this way can then also be compared with the data set that has been read out. In this way, a double check can be used to achieve greater security in the identification of persons. It is also conceivable that these two identification methods are used alternatively. If, for example, the portrait photograph that has been read out is out of date, but a fingerprint is stored in the identification document, a successful comparison of the portrait photographs can be dispensed with and the successful comparison of the fingerprint can be relied on instead.

If an automatic, successful comparison is not possible, there is the option that the portrait picture as well as the read out portrait image are transmitted to a border official for manual checking. If he comes to the conclusion that both recordings belong to one and the same person, he can open the exit door 1 manually. Alternatively, he can also carry out a manual check of the identification document together with a visual inspection of the person to be identified. At this point at the latest, the exit door 1 opens for the now identified person, whereupon the pass-through control system becomes free and, after the exit door 1 has been closed, the readiness for admission is again signaled via the display 26. <b> List of reference symbols: </b> BZ description BZ description 1 Exit door 26th advertisement 2 Door leaf 27 railing 3 Attachment 28 upper edge of the railing 4th carrier 29 Railing wall 5 Camera system 30th Security Camera 6th movable unit 31 holder 7th casing 32 Swivel axis 8th drive 33 Fixation 9 Portrait camera 34 Door frame 10 released area 35 Hand biometric sensor 11 back 36 Passage 12th front 37 Lighting control 13a, b, c side walls 38 Cable cover 14th screen 39 transparent opening 15th entrance 40 thickened area 16 Guide rail 41 Cable opening 17th Guide carriage 42 Live image camera 18th Drag chain 43 Back plate 19th Support rail 44 Window opening 20th Electric motor 45 Mainstay 21 Railing foot 46 Timing belt 22nd Lighting device 47 Transfer point 23 Reader 24 screen 25th scanner
