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 fastened to a support for suspension, the door leaf comprising a transparent material, on 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 the vertical direction within the housing, the movable unit comprising a portrait camera, the movable unit defining a swept area in a front view via the travel path and the area of the movable unit, the swept area minus the area of the movable aren unit determines a released area, wherein the housing has a back and a front, the back being connected to the front of the housing via side walls.

Such a passage control system, for example for airports, is already out WO 2010/078856 A1 known and includes an entrance door made of glass, an exit door made of glass and an intermediate passage. 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 an submitted identification document, in particular an ID photo. The person to be identified then passes the open front door, which then closes again. It 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 picture on the screen and, if necessary, correct it on instruction. A computing unit compares the camera image with the read ID card photo and opens the exit door if there is a match.

The camera system WO 2010/078856 A1 comprises a drive arranged on the exit side of the exit door near the swivel axis, which carries the movable unit. The movable unit is enclosed and not attached to the door leaf for the purpose of being movable, but 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 the area of the guide carriage, dust quickly gets between the guide carriage and the guide rail. The preferably quickly movable unit can also hurt 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 includes a front and a rear, which are connected to each other via side walls. The housing forms a closed space, which contributes significantly to the longevity of the movable unit and in particular the sensitive drive and also 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 shooting conditions (sufficient lighting, several single photos, correct height position, etc.) and with the latest artificial intelligence or algorithms, the camera photo cannot be assigned to the ID photo. For this reason, border guards are often stationed behind the passage controls, who carry out a manual check if necessary. Another task of the border guards is to monitor the area of the passage controls. A disadvantage of these known systems from practice is that the border guards do not have an unobstructed view into the passage, because the housing, which is quite large due to the movability, blocks the view into the passage. The invention is therefore based on the object of offering border guards better surveillance of the passageways.

This object is 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 entrance side and an exit side, the door leaf being fastened 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, the movable unit being movable in the vertical direction within the housing, the movable unit comprising a portrait camera, the movable unit defining a swept area over the travel path and the area of the movable unit in a front view, the swept area hey minus the area of the movable unit, determines a released area, 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,
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 multitude 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. This enables fundamentally better surveillance, which also does not require any border guards on site. However, it was found that this type of surveillance is tiring for border guards and subsequently provokes negligence. It was also found that this type of monitoring is too complex even for artificial intelligence, so that this type of monitoring does not appear to be possible in the foreseeable future.

Another way of better monitoring the passageways is to arrange the camera system not on the exit door but on the side walls of the passageway, so that the exit door made of glass ensures that border guards have a clear view of the passageway. 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 must be directed to the camera system on the side wall. The steering can take place 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 guards stationed behind the passage control find this to be sufficient for their work. The border guards can perceive and interpret all essential movements of the people to be identified. This type of surveillance is significantly less tiring for border guards and at the same time enables a high throughput of people to be identified. As a result, the above-mentioned task is solved particularly satisfactorily.

The above-mentioned 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 fastened to a support for suspension, the door leaf comprising a transparent material , 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 immovably fixed relative to the door leaf , 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 over the travel path and the area of the movable unit in a front view, the swept area being less The area of the movable unit determines a released area, 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 any noticeable scatter, so that preferably an observer who sees through the transparent material recognizes a sharp image. Transparent materials are, for example, glasses for window panes or acrylic glass (polymethyl methacrylate, PMMA). The term “transparent materials” also includes safety glasses or polycarbonates. It is preferred that opaque materials are excluded from the term “transparent materials”. Even more strongly scattering materials are not included in the expression “transparent materials”. The term "strongly scattering" means those materials in which the outlines of people are no longer sharp and the contours only appear as diffuse shadows. The term “transparent” can refer to one or both directions. It is possible that the door leaf is provided with a reflective coating, so that only the viewing direction from the exit side to the entrance side of the door leaf is possible.

The passage control system is expediently designed as a one-way path. If a person to be identified stands in front of the exit door and waits for it to open, the side of the door leaf facing the person is the entry side, while the other side of the door leaf is the exit side. An inspection of the passage control system with a view of the entrance side of the door leaf corresponds to a front view of the passage control system or the respective component. The view from the opposite direction thus corresponds to the rear view of the passage control system or the respective component. The exit door or that Passage control system expediently defines a direction of passage.

The expression “immovably fixed” preferably means that the housing is fixed to the door leaf, for example by means of screws or by gluing or by latching means, and then - apart from loosening the connection between the housing and the door leaf - is no longer movable relative to the door leaf.

The expression “swept area” preferably means the area which is determined by the area of the movable unit in a front view when all height positions are moved one after the other. For example, in the case of a movable unit with a purely rectangular outline in the front view, a swept area results from the width of the rectangle of the movable unit multiplied by a height difference between the upper edge in the highest height position and the lower edge in the lowest height position of the movable unit . The movable unit preferably has a travel path in the vertical direction of at least 0.5 m or 0.7 m or 0.8 m.

The transparent opening 39 from the front view 3rd is preferably designed as a hole through the transparent material of the door leaf 2nd is covered. The transparent opening 39 is preferably designed such that it covers a swept surface of the movable unit 6 corresponds or essentially corresponds. The swept area minus the area of the moveable unit 6 in a front view there is a free area 10th , through which in this exemplary embodiment both the person to be identified and people can see through from the exit side.

In 4th is a rear view of the camera system 5 shown, in this figure a back plate 43 was omitted to look at the inside of the camera system 5 to release. The interior is primarily a drive 8th which the movability of the moveable unit 6 guaranteed. The drive 8th includes in particular an electric motor 20th in the form of a stepper motor with brake, a guide rail 16 with a timing belt 46 , a support rail 19th as well as a sledge 17th on the guide rail 16 . Further components of the drive, not shown here, can be, for example, a motor controller or a DC voltage supply.

The electric motor 20th This exemplary embodiment may draw a nominal current of 4 A and exert a holding torque of 3.5 Nm during the step angle 1 , 8 °. The electric motor 20th drives the timing belt 46 on which is arranged circumferentially in the height direction and with which the guide carriage 17th connected is. The sledge 17th in turn is with the movable unit 6 connected, which this embodiment also includes a cable cover 38 having. The cable cover 38 is also preferred with the support rail 19th connected so that the movable unit 6 on both sides on rails 16 , 19th is stored, which gives additional stability.

In the cable cover 38 In this exemplary embodiment there are cables for a 24 V power supply, an RS485 bus, a CAN bus, an Ethernet cable and an earth cable. The cables are expediently from the screen 14 or the Kammeras 9 , 42 through the cable cover 38 through to a drag chain 18th guided. In 4th can be seen that the drag chain 18th a certain space to the side of the guide rail 16 claimed so that the thickened area 40 arises. The drag chain 18th ensures a minimum radius for cable bends so that the cables are protected. The cables are inside the drag chain 18th up to a preferred upper transfer point 47 the drag chain 18th and from there statically fixed down.

Preferably inside the side wall 13c and more preferably below the electric motor 20th there are other components of the drive 8th , for example the motor control or the 24 V DC voltage supply. Some of the cables are expediently through the cable opening 41 in 4th led to the outside, including the grounding cable, at least one cable for the power supply, and the Ethernet cable. The latter preferably transmits the recorded portrait photos to a computing unit of the passage control system or the control system or a higher-level server. Finally, there is a lighting control in a lower area 37 arranged, which with the lighting device 22 connected is.

In 5 is the rear view of the camera system 5 shown, however in contrast to 4th the back panel 43 the drive 8th completely covered. The back panel 43 has a window opening 44 on, which in this embodiment consists of a transparent plastic, for example polycarbonate. The window opening 44 the back plate 43 corresponds in size to the transparent opening 39 the front. In this way, the camera system ensures 5 a transparency both with a view of the passage 36 in as well as looking out of it. As a result, the person to be identified has less of the feeling of being locked up. However, border guards in particular have a special feature on the exit side of the exit door 1 a better insight into the passage 36 and, if necessary, can better observe the people to be identified there and interpret their actions better.

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 ad 26 indicates with a green field that the person can enter the passage control system. The person approaches the reader, recognizes the intuitively presented instructions on the screen 24th of the reader 23 and then places your identification document on the scanner 25th . The data of the identification document are read out and transferred to a computing unit. The front door then opens 15 inside so that the person's passage 36 can enter.

Then the front door closes 15 again and the person is removed from the surveillance camera 30th supervised. Because of the structure of the passage control system, in particular because of the exit door that can be intuitively recognized as an exit door 1 , the person approaches the exit door 1 . In this embodiment, the opening of the entrance door is activated 15 also facial recognition of the camera system 5 , which on the recordings of the live image camera 42 falls back. Since faces can be recognized as faces from a distance of several meters, the camera system is 5 of this embodiment, the face of the approaching person always strives approximately in the middle of the recording area of the live image camera 42 to keep. This means that the movable unit fits 6 with each step of the approaching person their height position to the height of the person to be identified. As a result, the movable unit moves 6 calmer and more even so that it does not have to move quickly only when the person is right in front of the exit door 1 stands.

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

Via the live image camera 42 determines the camera system 5 in this exemplary embodiment also whether the face of the person to be identified is sufficiently illuminated. For this purpose, images from the live image camera 42 to the lighting control 37 which checks whether stronger or weaker lighting is required. A corresponding signal is then sent to the lighting device 22 spent to adjust the lighting. Once the camera system 5 or the lighting control 37 In addition to the correct position of the face and the correct illuminance, a trigger signal is sent to the portrait camera 9 issued, which then takes a portrait of the person to be identified. The portrait camera 9 has a relatively high resolution, which allows for example portrait shots with 13 MP. In contrast, the resolution of the live image camera may only be 2 MP.

The portrait is then preferably transmitted to the computing unit via the Ethernet cable or compared with the image of the identification document read out. This comparison may be carried out, for example, using artificial intelligence in the form of a neural network. If the selected portrait of the person to be identified with the portrait of the portrait camera 9 matches, the exit door opens 1 by an electric motor's swivel axis 32 actuated and the door leaf 2nd together with the camera system 5 is swung open to the outside.

Optionally, before or after the portrait takes place but in any case before the exit door 1 opens on the screen 14 instructions are given that the person's hand or finger of the hand on the sensor 35 for hand biometrics. The fingerprint or handprint determined in this way can then also be compared with the read data record. In this way, greater security in identifying people can be achieved by double checking. It is also conceivable that these two identification methods are used alternatively. For example, is the read out Portrait shot is still out of date but a fingerprint is stored in the identification document, so that a successful comparison of the portrait shots can be dispensed with and instead the successful comparison of the fingerprint can be relied on.

If an automatic successful comparison is not possible, there is the option that the portrait picture as well as the selected portrait picture are transmitted to a border official for manual verification. If he comes to the opinion that both recordings belong to the same person, he can manually exit the door 1 to open. Alternatively, he can also manually check the identification document and inspect the person to be identified. Then the exit door opens at the latest 1 for the now identified person, whereupon the passage control system becomes free and after closing the exit door 1 again via the display 26 the willingness to accept signals.
