Description

[0001] The invention relates to a method for operating a revolving door with a sliding door function, a revolving door with a sliding door function, and a computer program product for operating a revolving door with a sliding door function.

[0002] A revolving door, sometimes also called a pivot door, has two or more door leaves that rotate within a circular housing. The door leaves can be mounted on a rotating central axis and optionally driven by this axis. Alternatively, the door leaves can be mounted on an outer ring guide within the housing and driven by this guide. Revolving doors restrict the entry of outside air into a building and can therefore contribute to energy savings.

[0003] If revolving doors are classified according to their drive mechanism, three basic types can be distinguished. First, there are manually operated revolving doors without a drive. With these, the door leaves must be set in motion manually by the person passing through. There are also revolving doors where the door leaves are only assisted by a drive mechanism. The door leaves do not rotate, or only very slowly, without external input. When a person pushes a door leaf, the drive assists the resulting rotation or helps overcome the initial inertia, after which the person passing through continues pushing independently without motor assistance. Revolving doors of this type are called semi-automatic revolving doors (or "low-energy revolving doors"). Finally, there are fully automatic revolving doors (or "full-energy revolving doors").In these systems, the door leaves are driven in such a way that they move independently, that is, without external influence from a person.

[0004] There are revolving doors where one or more of the door leaves function as sliding doors. For this purpose, one door leaf can have a movable sliding door element. This element is preferably motorized to create a passage through the revolving door, as an alternative to the usual way of walking through a revolving door with the rotating movement of the door leaves. The door leaf thus forms a sliding door. In the case of a double-leaf revolving door with two door leaves, the two affected door leaves typically form a sliding door, for example, with an opening between them. However, there are also, for example, three- or four-leaf revolving doors, or even more than two, where one or more of the more than two door leaves have a sliding door element and can form one or more sliding doors.In an example with three door leaves, it is also possible to equip only one or two door leaves with a sliding door element. This sliding door element is typically positioned further outwards, radially speaking, relative to the door leaf, and can move towards the surrounding revolving door frame or towards the pivot point. These revolving doors with a sliding door function generally have two operating modes: In the first operating mode, the sliding door(s) of the revolving door are closed. In this case, the revolving door can only be passed through when the door leaves are rotating. In the second operating mode, the sliding doors are open or can open and close like a conventional sliding door. In this state, the door leaves preferably do not rotate, and an opening in the sliding door is not possible.The sliding doors, formed by the relocation of the sliding door elements, can be passed through when open. These sliding doors can, of course, also be closed and locked in the aforementioned second operating mode, so that passage through the revolving door is not possible in this closed state. The sliding door function can be particularly advantageous if bulky items need to be transported through the revolving door or if there is a high volume of traffic. With the sliding door open, the revolving door can be traversed more quickly than in the classic rotating revolving door operation, but the air exchange is not restricted to the same extent as with a closed sliding door. In everyday use, a distinction is made between these two operating modes (rotating and sliding).Sliding door operation) can be changed manually, for example by manually pressing a button provided for this purpose, if this is considered appropriate by the building staff, for example.

[0005] In contrast, the invention is based on the objective of providing an improved method for operating a revolving door with a sliding door function, a revolving door with a sliding door function that uses this method, and a computer program product for carrying out the method.

[0006] The problem is solved by providing the method for operating a revolving door with a sliding door function according to claim 1, the revolving door with a sliding door function according to claim 14, and the computer program product for operating a revolving door with a sliding door function according to claim 15. Advantageous embodiments are the subject of the dependent claims and the following description. It should be noted that the features listed in the independent and dependent claims can be combined with one another in any way, provided this is technically feasible. This also applies across the boundaries of the claim categories and even if one claim is not dependent on another. The description further characterizes and specifies the invention, particularly in conjunction with the figures.If elements in the patent claims or the description are designated with numerical words such as "first", "second", etc., the numerical words serve only to make the elements distinguishable, but do not make any statement about an order, a total number or other properties of the elements, unless this is explicitly indicated.

[0007] The key finding here is that by using sensors to detect pedestrian movement and strategically applying the acquired sensor data, the transition to and from sliding door mode can be optimized. As proposed, this allows for automated switching between sliding and revolving door modes, eliminating the need for conscious user action. The switch between sliding and revolving door modes, or "rotational operating state," occurs automatically. This automation has a positive impact on traffic flow, as it prevents congestion in front of the revolving door.

[0008] Specifically, according to a first independent aspect of the disclosure, as set out in claim 1, a method for operating a revolving door with a sliding door function is proposed, which method comprises at least the following steps a) to e): a) Providing a revolving door with a door leaf assembly comprising at least two door leaves, a rotary drive for rotating the at least two door leaves within a passage area of ​​the revolving door, and at least one sensor for detecting pedestrian movement, wherein the door leaf assembly further comprises at least one sliding door element, the sliding door element being drive-assisted such that a sliding door passage through the at least two door leaves can be opened and closed with motor assistance in a sliding door mode. b) Acquiring initial sensor data concerning pedestrian movement using the at least one sensor. c) Performing an initial analysis of the initial sensor data. d) Automatically determining, based on the initial analysis, that the revolving door should be switched to sliding door mode.

[0009] The proposed method can be applied to semi-automatic or fully automatic revolving doors, with application to fully automatic revolving doors being preferred. Similarly, the proposed revolving door can be either semi-automatic or fully automatic, with the fully automatic revolving door being preferred for the proposed sliding door function.

[0010] The term "semi-automatic revolving door" refers to a revolving door that is both motor-assisted and requires manual push-starting by a person to pass through it. The term "fully automatic revolving door," on the other hand, refers to a revolving door that is entirely motor-driven and requires no manual push-starting by a person for its intended use; in fact, manual push-starting is strictly prohibited or must be prevented. A "drive" is a mechanical device that sets the revolving door leaves in motion. In the case of a "rotary drive," this sets the leaves in their intended rotational movement, and in the case of a "sliding door drive," it sets the intended lateral sliding and thus opening movement of the door leaf equipped with a sliding door function.The sliding door mechanism involves the opening of two or more door leaves equipped with a sliding door function (opening of the sliding door element(s) of the door leaf assembly). The sliding door drive allows the sliding door element(s) to be moved with drive assistance. The sliding door opening, which is formed, for example, between the door leaves or between the door leaf and a revolving door frame located further out in the radial direction, is opened by a lateral movement of the sliding door element(s), thereby causing the revolving door to assume the sliding door open position.

[0011] In the operating mode where the sliding door function is active and the opening and closing of one or more sliding door openings is achieved by laterally shifting the door leaf(s), the revolving door is also referred to as being in sliding door mode. In this sliding door mode, the sliding door opening (or openings) can be either open (the so-called "sliding door open state") or closed (the so-called "sliding door closed state"). If, however, the sliding door function is not to be used for people to pass through, but rather the rotational movement of the revolving door is to be used for this purpose, then this is referred to as the classic revolving door mode or the "rotational operating state." In this rotational operating state, the...The sliding door element(s) are usually closed (so that a "sliding door closed state" is generally present here as well).

[0012] "Sensors" are devices that detect the movements and / or positions of people. A sensor is assigned a detection area, or a sensor system can have multiple detection areas. The proposed sensor can have a detection area in front of and / or inside the revolving door.

[0013] Furthermore, a "passage area" can be defined for the revolving door, which is the area through which people can pass through the revolving door. In rotation mode, when the door leaves are turning, this passage area is continuously adjusted due to the revolving door's rotation. In sliding mode, when the revolving door is in the sliding door opening position and the sliding door element(s) are open, the passage area is static, and the revolving door can be easily passed through like an open sliding door (or several open sliding doors). For example, with a double-leaf revolving door and a sliding door opening formed between the two leaves, this means simply passing through the two access openings of the revolving door and the open area between the two leaves when the sliding door is open.

[0014] A person enters the interior of the revolving door, which encompasses or provides the passageway, via an "access area." The access area is also variable during rotation, as an outer edge of a door leaf temporarily partially occupies the access area or divides it into two parts.

[0015] Basically, a revolving door has an "access opening" (or two opposing access openings), which is either completely open, allowing a person to enter the passageway of the revolving door (and thus its interior) through one of the resulting access areas. Alternatively, the access opening may be divided (or even covered) by an outer edge of a door leaf, so that a person can enter the passageway of the revolving door (and thus its interior) through either the left or right of the door leaf.

[0016] The term "door leaf arrangement" preferably refers to a combination or sum of several or all door leaves of the revolving door, which can be driven individually or together. The rotary drive can, as proposed, enable fully automatic or semi-automatic operation. The detection area is preferably defined by an area extending either in front of one or two access openings of the revolving door. This area preferably extends three-dimensionally in space, so that, in particular, persons located near the revolving door can be detected at their full height. It is possible for the detection area to be formed by areas that are not contiguous with each other.

[0017] The door leaf arrangement can be formed by two or more door leaves, as proposed. An advantageous embodiment features two door leaves, arranged, in particular, slightly spaced apart, each with a sliding door element, such that a single sliding door opening is formed between the two door leaves when the two sliding door elements are moved laterally. However, other configurations are also possible, for example, each of the two door leaves could have only one sliding door element, the movement of which would then create the sliding door opening.Furthermore, door leaf arrangements with more than two door leaves are also conceivable, whereby their exact orientation and dimensions, as well as the dimensions of the sliding door elements, are essentially freely selectable, as long as the following conditions are met: It is essential that, in the open sliding door position, it is possible to pass through the revolving door via a sliding door opening, even though the door leaf arrangement is not currently rotating, and that, when the sliding door opening is closed or the sliding door is closed, the revolving door cannot simply be passed through unless the door leaf arrangement is rotating, i.e., in active rotation mode. In a possible design with, for example, three or more door leaves, the sliding door opening could...The sliding door openings are then formed between a door leaf with a sliding door element and a revolving door frame arranged further outwards in radial terms.

[0018] According to advantageous embodiments of the invention, a sensor arranged on a frame or housing of the revolving door can detect the detection area. However, the at least one sensor can also be mounted elsewhere: For example, it is proposed that the at least one sensor be attached to a building wall or ceiling in an interior or exterior area of ​​a building in which the revolving door is installed. The use of multiple sensors in different positions is entirely possible and can prove advantageous. The at least one sensor can, according to the proposal, be a radar sensor, a lidar sensor, a camera, or another type of sensor. Furthermore, detecting an area within the revolving door can also be helpful, for example, to determine how many people are currently inside.For this purpose, sensors can also be arranged inside the revolving door, for example on at least one of the door leaves or on a ceiling wall of the revolving door.

[0019] In the closed position of the revolving door, the door leaves are closed by the sliding door element(s). In this closed position, the door leaf assembly can rotate automatically in a fully automatic mode, or it can operate semi-automatically, requiring a push to initiate rotation. When the revolving door allows passage by rotating the door leaves, this can also be referred to as the rotational operating state or the (classic) revolving door mode. This can also refer to a stationary state, i.e., when the door leaves are at a standstill, as long as the revolving door remains capable of allowing passage to arriving individuals by rotating the door leaves.However, situations may arise where activating the sliding door function is desirable and the door should switch to the sliding door opening position to allow people to pass through. For this to work, the revolving door must be set to a sliding door mode, so that when someone wants to enter, a sliding door opening is enabled instead of, for example, passage via the rotation of the door leaves. As proposed, based on the initial analysis, it will be determined whether the revolving door should be set to this sliding door mode.

[0020] In particular, the initial analysis can also determine whether the sliding door opening between the door leaves, or between the door leaf and the revolving door frame, should also be opened. In this case, the sliding door elements are moved laterally. For the purposes of this disclosure, this is preferably understood to mean that all door leaf elements of the door leaf arrangement are moved laterally outwards from their central closed position, as viewed from the center of the revolving door, towards their open position; or that this applies only to selected door leaf elements; or that the movement of the sliding door element or...The sliding door elements are moved into an open position such that a radially outer sliding door element is shifted inwards towards the center of rotation and one or more sliding door passages are opened between the door leaf and the radially outer carousel door frame.

[0021] Preferably, each door leaf is equipped with a sliding door element, although variations are also conceivable in which one door leaf is equipped with several sliding door elements or at least one sliding door element is multi-part. To move the sliding door elements, the revolving door can, as proposed, have at least one sliding door drive (also called a relocation drive). For example, each sliding door element can be assigned its own sliding door drive / relocation drive. As soon as the sliding door elements have been moved so that passage through the door leaf assembly is possible (through the sliding door opening), the revolving door is in the sliding door open position.

[0022] The proposed system enables an automatic, sensor-based transition from the rotational operating state or the sliding door closing state to the sliding door mode or the sliding door opening state. This can, for example, prevent crowding in front of the revolving door during periods of high pedestrian traffic. The described method is preferably implemented as a computer-based system. This can preferably be carried out by a data processing device integrated into the revolving door.

[0023] One advantage of this method is the optimization of the automatic, case-specific switching between revolving door mode (rotational operating state) and sliding door mode. This allows for more efficient management of overall traffic flow and also enables the revolving door to accommodate bulky objects.

[0024] The proposed method is preferably designed to include the following step: e) Controlling at least one sliding door drive of the revolving door and thereby opening the sliding door passage by moving the sliding door element upwards, whereby the revolving door changes into a sliding door opening state.

[0025] In particular, the revolving door changes from the previously prevailing rotational operating state, in which the sliding door passage is also closed, and thus also from the sliding door closing state, to the sliding door opening state, and basically, as already explained, to the sliding door mode.

[0026] The proposed method is preferably designed such that, in the sliding door opening state of the revolving door, in which the at least one door leaf is open, the following steps are performed: Acquisition of second sensor data concerning person movements by means of the at least one sensor (receiving second sensor data from the at least one sensor); performance of a second analysis of the second sensor data from the at least one sensor; and determination, based on the second analysis, that the sliding door opening should be closed. The at least one sliding door drive (a displacement drive) of the revolving door is then activated, whereby the sliding door opening is closed by closing or displacement of the sliding door element, thereby switching the revolving door into a sliding door closing state, and in particular, further into a rotation operating state.The sliding door function can therefore be deactivated if this is appropriate. This can be useful, for example, if the number of people in the area of ​​the revolving door has decreased again.

[0027] Preferably, in the rotational operating state—or, in particular, simultaneously in the sliding door closing state—the rotary drive of the revolving door is controlled such that it sets the door leaf assembly into an automatic rotational movement. If, based on the initial analysis, it is determined that the sliding door opening is to be opened, the rotary drive is preferably controlled to stop the rotational movement of the door leaf assembly. This describes one way to control the revolving door in fully automatic operation. Thus, the door leaf assembly is initially in automatic rotational movement and therefore does not need to be pushed by a person. However, when the sliding door function is activated, i.e., when the revolving door is switched to sliding door mode, the rotary drive should then be stopped.If a passage is to be opened through the door leaves (via the sliding door opening), then, according to this embodiment, the rotation of the door leaf assembly or the door leaves themselves is stopped. Preferably, the rotation does not end abruptly, but rather the rotational speed is reduced over a certain period. This allows people passing through the revolving door to adjust to the change in operating mode.

[0028] It is advantageous if the at least one sliding door drive is only controlled in such a way that the sliding door opening is opened by moving the sliding door element after the rotational movement of the door leaf assembly has ceased or after the door leaf assembly has fallen below a predefined rotational speed. Thus, the sliding door opening is advantageously only opened when the door leaves have come to a complete stop or at least almost to a complete stop.

[0029] In a particularly advantageous embodiment of the proposed method, the rotary drive is controlled to terminate the rotational movement such that the door leaf assembly assumes a predefined desired rotational position. This predefined desired rotational position is a defined angular orientation of the door leaf assembly. Preferably, this is an angular orientation in which the door leaf assembly is easy to pass through. For example, it is advantageous if, in the case of two door leaves, the door leaves are aligned essentially parallel to the access openings of the revolving door. Such a position is particularly preferred for a double-leaf revolving door. This position can also be called the 0° position.

[0030] With the proposed revolving doors and their corresponding operating procedures, it is generally possible to use various types of revolving doors, with the double-leaf revolving door being the preferred option. Double-leaf revolving doors, in which two door leaves run in a line and enclose an angle of 180°, can be used. Depending on the specific type of revolving door and the number of door leaves, different maximum possible opening angles for the access area result. For the aforementioned and preferred double-leaf revolving door, the maximum opening angle can be, for example, 60°, and this opening angle can generally be provided as a pedestrian access angle over a longer rotation range, even during operation. As previously described, the desired rotational position can be preset.For example, with a double-leaf revolving door, the 0° position may be the preferred rotational position. This position can ensure a maximum opening width of 60°, representing the maximum usable opening angle given the structural constraints (maximum utilization of the access opening without obstructing the outer edge of a door leaf). Furthermore, the 0° position can provide a certain amount of free depth in the passageway, giving people space in the direction of rotation to enter the interior. At the same time, the maximum opening width of 60° is maintained for a certain period, even if the door rotates an additional 45°. This allows subsequent people to enter the same passageway while the revolving door is in rotation. For the sliding door mode, or...For moving the sliding door into the open position and using the revolving door with the sliding door open, this 0° position is also preferred, since the three openings then available (both access openings and the sliding door passage) are aligned parallel to each other and can lie in a line or straight direction of movement.

[0031] According to an advantageous embodiment, the basic control of the rotary drive can be achieved such that the rotary drive assists a rotational movement of the door leaf assembly when a person pushes the door leaf assembly. In this variant of the method, the revolving door is therefore operated semi-automatically. The door leaf assembly does not rotate on its own, or only very slowly, if it is not pushed. Ultimately, people wishing to pass through the revolving door must push the door leaves. If, based on the initial analysis, it is determined that the sliding door passage is to be opened, then preferably one of the following two steps is carried out before the sliding door passage is opened by moving the sliding door element: a) According to a first alternative, the rotary drive is controlled in such a way that the rotational movement of the door leaf assembly is stopped. Optionally, this is done in such a way that the rotational movement of the door leaf assembly is only stopped when the door leaf assembly, pushed by the person, has reached a predefined desired rotational position. Thus, according to this embodiment of the method, in semi-automatic operation, the door leaf assembly is allowed to continue being pushed and the rotational movement of the door leaf assembly is only stopped when the desired rotational position is reached. For this purpose, the rotary drive can preferably brake and / or stop the rotational movement of the door leaf assembly in a suitable manner, which can also be done continuously. A brake can optionally also be used for braking or stopping.Once the desired rotational position is reached, the door leaves can preferably no longer be moved manually, and the sliding door elements are opened or moved laterally. b) If, in semi-automatic operation, it is determined that the sliding door opening should be opened, then, according to a second alternative, the rotary drive can be controlled in such a way that it sets the door leaf assembly in an autonomous rotational movement, which then ends when the door leaf assembly has reached the predefined desired rotational position. The door leaf assembly thus assumes the desired rotational position in virtually fully automatic operating mode, without the need for a person to push it, which may, for example, manifest itself in a generally faster rotational movement with a higher rotational speed (which then needs to be slowed down shortly before or from the desired rotational position).

[0032] Preferably, when the sliding door opening is to be opened or closed, a warning device on the revolving door is activated to emit a visual and / or audible signal. This device can be either an audible or a visual signal generator (e.g., a loudspeaker, a warning light, or the like). The warning device can be activated, for example, before the sliding door element(s) are moved to open or close. However, it is particularly preferred that the warning device is activated before the door leaf assembly is moved into the desired rotational position, i.e., the starting position for opening or using the sliding door opening. Furthermore, it can be provided that the warning device is activated at a predefined time interval before the sliding door element(s) are moved.For example, once the initial analysis determines that the sliding door mode should be activated, or even that the sliding door opening should be opened, or once the second analysis determines that the rotation operating state should be activated again, or that the sliding door opening should be closed, a warning signal can first be issued via the warning device. A predefined time interval is then observed before the sliding door element(s) are moved.

[0033] According to an advantageous embodiment of the invention, the method is designed such that, during the first analysis, position data, movement data, and / or status data relating to at least one person and / or at least one object within the detection range are taken into account. The object can, in principle, be any object, for example, a package, a suitcase, a piece of furniture, a stretcher, a hospital bed, or even a motor vehicle. Position data preferably refers to data specifying the position of the at least one person or object, for example, XY coordinates. The position data is preferably determined during the first analysis based on the initial sensor data, for example, by means of image recognition methods.

[0034] The motion data preferably consists of data indicating how fast the at least one person or object is moving and / or accelerating. This motion data is also preferably acquired based on the initial sensor data. As proposed, initial sensor data acquired at different times can be evaluated to determine the motion data. Position and / or motion data for multiple people or objects can be determined, evaluated, and considered. It is also possible to combine this position and / or motion data to, for example, determine the position or speed of a group of people.

[0035] The condition data preferably refers to data concerning the condition of at least one person or at least one object, whereby this term is to be interpreted broadly. In particular, condition data may include body orientation, posture, especially sitting or lying position, facial expression, gestures, direction of gaze, height or estimated weight of a person, as well as size, length, width, depth, and / or estimated weight of the at least one object.

[0036] The first analysis preferably includes an assessment of whether predefined limits are exceeded individually or in total with regard to position data, movement data, and / or status data; whether there is a congestion in or at the revolving door; and / or whether there is a risk of a congestion in or at the revolving door. Optionally, a regular and / or current rotation speed of the door leaf assembly is used for this assessment. In the rotational operating state or sliding door closing state, the number of people who can pass through the revolving door per unit of time is limited by the rotation speed of the door leaf assembly, geometric constraints, and ultimately also the diameter of the revolving door. The assessment is advantageously based on whether, for improved pedestrian flow, or...To avoid congestion at the revolving door, a switch to sliding door mode and then, if necessary, directly to the sliding door's open position may be required. However, in addition to pedestrian flow, other parameters can also be considered, for example, whether an object is so bulky that it cannot be moved through the revolving door, or only with great difficulty, when it is in rotation. The evaluation should preferably be carried out by a computer.

[0037] The evaluation can be based on predefined values ​​and metrics, for which algorithms familiar to experts can be advantageously used. Alternatively or additionally, the evaluation can be carried out using machine learning methods. For this purpose, various situations can be recorded during a training phase, for example, with different groups of people or with different objects. The system learns in which situations a transition from the rotating operating state to the sliding door mode, or possibly also from the sliding door closed state to the sliding door open state, is useful, for example, through supervised learning.

[0038] The assessment can optionally consider a regular and / or current rotation speed of the door leaf assembly. This can be advantageous because, for example, a higher rotation speed of the door leaf assembly allows more people to pass through the revolving door per unit of time. Thus, the limit values ​​are advantageously modified depending on the rotation speed and / or the risk assessment regarding the formation of congestion is adjusted. The regular rotation speed refers to the rotation speed of the revolving door during normal operation or the preset speed.

[0039] The proposed procedure preferably includes determining whether at least one person in the detection area wishes to pass through the revolving door. To determine this intention, the body orientation, posture (especially sitting or lying positions), facial expressions, gestures, and / or gaze direction of the at least one person in the detection area are evaluated. A person for whom an intention to pass through has been determined is weighted differently in this evaluation than a person for whom no intention to pass through has been determined. It is quite possible that there are people in the detection area who do not wish to pass through the revolving door. These individuals are of little or no significance for the decision as to whether to switch to sliding door mode.For example, the sliding door mode should only be activated, or the sliding door opened, for a person carrying a bulky item if that person actually intends to pass through the revolving door. Furthermore, people who are merely near the revolving door but do not intend to pass through it do not contribute to a congestion risk at the revolving door.

[0040] This fact can be taken into account, as proposed, by giving less weight, or even no weight at all, to these individuals and / or their data in the previously described assessment process of whether certain thresholds are exceeded, whether a traffic jam exists or could develop. A suitable weighting is advantageously applied for this purpose. Consideration of the desire to enter the area can also be achieved through the application of machine learning methods. In particular, machine learning methods can also be used to determine the desire to enter the area. Further aspects for determining a desire to enter the area or for analyzing recorded sensor data and people movements are known from EP 4 095 341 A1, the contents of which are hereby incorporated into the present application. Reference is also made to the applicant's MotionIQ technology.

[0041] A person's body orientation away from the entrance of a revolving door can indicate that they do not intend to enter. Body posture can also clarify this, for example, if a person is sitting or lying down. In this case, the person is unlikely to intend to pass through the revolving door in the near future. Information regarding facial expressions, gestures, or gaze direction can also be used to infer a person's intention to pass through the revolving door. Combinations of these parameters can also be evaluated, and the aforementioned parameters can be recorded at multiple points in time to further assess the person's intention to enter or pass through the revolving door.Thus, according to advantageous embodiments of the invention, even complex situations can be captured and taken into account accordingly: For example, it could be determined that a person is merely waiting in front of the carousel door and does not want to enter the carousel door because, for example, they are smoking or looking at their smartphone.

[0042] According to a particularly advantageous embodiment of the proposed method, the first analysis includes detecting whether a group of people is approaching the revolving door whose number exceeds a predefined threshold, and / or whether a person is approaching the revolving door at a speed below a predefined threshold. A sufficiently large group of people can be allowed to pass through by switching to sliding door mode and finally to the sliding door's open position. Advantageously, a predefined threshold for the size of the group of people can be used for detection. This threshold is preferably determined by the diameter of the revolving door. Whether a group of people is present and whether the group is actually approaching can optionally be determined based on the density of people in the detection area and / or on the direction of movement of the group of people.

[0043] If a person approaches at a particularly slow speed, such as a wheelchair user or someone with a walking disability, the system can switch to sliding door mode and ultimately to the sliding door open position. This is because the person might not be able to safely pass through the revolving door due to the potentially excessive rotational speed of the door leaf assembly. A threshold value, determined by the rotational speed of the door leaf assembly, can be implemented for this purpose. Machine learning methods can be advantageously employed to identify this group of people—a slow-moving individual, a wheelchair user, or someone with a walking disability—and for related evaluation tasks.

[0044] It can further be proposed that the initial analysis considers the number of people, the density of people, the dwell time of one or more people, the speed of movement of one or more people, the number of people in relation to a specific time period, the movement pattern of one or more people, and / or the dimensions of a moving object within the detection area. The density of people refers to the number of people per unit area. Dwell time preferably refers to how long a person remains at a position or in an area of ​​a specific size within the detection area. It is particularly advantageous to consider an average dwell time of people in the detection area, a median dwell time of people in the detection area, and / or a maximum dwell time of a person in the detection area.It can also be checked whether a specific number of people appear in the detection area within a certain period. It is also suggested that the number of people passing through the revolving door per unit of time can be taken into account, for example, how many people pass through the revolving door within a five-minute time window. The movement pattern can advantageously include a direction and / or path of movement of a person or object, and it is advantageously determined whether the person or object is moving towards an access opening of the revolving door. For all the aforementioned parameters, limit values ​​or other criteria can be provided to determine whether the revolving door should be switched to the sliding door opening state.

[0045] It is advantageous if the initial analysis includes determining a point in time at which a switch to sliding door mode, and optionally to the sliding door open state, is sensible and / or necessary. Preferably, the control of the sliding door drive or displacement drive, to shift the sliding door elements so that the revolving door assumes the sliding door open state, is only initiated at this point in time. If, for example, a person is approaching very slowly, it may be advantageous to wait before switching to sliding door mode and thus also to the sliding door open state, so that the revolving door can continue operating in the rotational state or sliding door closing state for as long as possible. The determination of this point in time is preferably based on determining the speed of at least one person or object within the detection range.

[0046] The preceding section explained various procedures, conditions, parameters, and criteria for determining, within and / or based on the initial analysis, whether a change of the revolving door to sliding door mode, and potentially ultimately to the sliding door open state, should be triggered. If the revolving door is already in sliding door mode, and potentially in the sliding door open state, and the second analysis aims to determine whether a change back to the rotating operating mode should occur (or perhaps only the sliding door opening should be closed), the aforementioned procedures, conditions, parameters, and criteria can still be applied, albeit with the opposite objective. Specifically, it must be determined whether the door should transition to or return to the rotating operating state or the sliding door closing state.The sliding door opening should be closed as soon as, for example, a traffic jam in and / or at the revolving door has cleared, there is no longer a risk of congestion in and / or at the revolving door, or as soon as a bulky object has passed through the revolving door. However, even with the sliding door opening closed, the sliding door mode can, of course, be maintained initially, and the sliding door(s) can continue to operate as a conventional sliding door. When more people arrive, the sliding door opening can be opened, allowing them to pass through in sliding door mode. However, switching back to the rotating operating mode is also possible and may even be preferable. To save energy, it is preferable to switch back to the rotating operating state (or, generally, to the closed sliding door state) as soon as possible.

[0047] Preferably, the method in the rotational operating state of the revolving door comprises the following steps: Receiving a first control signal to initiate a switch to sliding door mode, preferably also opening the sliding door opening, and in particular controlling the at least one sliding door drive or displacement drive, thereby opening the sliding door opening by moving or displacement of the sliding door element, thus switching the revolving door into a sliding door opening state. In the sliding door mode, in particular in a sliding door opening state, the proposed method preferably comprises the following steps: Receiving a second control signal to initiate a switch from sliding door mode back to the rotational operating state and / or to close the sliding door opening, and controlling the at least one sliding door drive or displacement drive.The revolving door is closed by a displacement drive, which closes the sliding door opening by moving the sliding door element, thus switching the revolving door to the closed sliding door state, and preferably continuing to the rotational operating state. A transition from the open sliding door state to the closed sliding door state, or generally from the rotational operating state to the sliding door mode, and vice versa, can therefore be initiated by a control signal. This signal can be triggered, for example, by a remote control, a push button, or a card reader, which first authenticates a user to change the sliding door mode. Consequently, a manual switch between the rotational operating state or sliding door mode, and, if desired, between the closed and open sliding door states, is also possible.

[0048] According to another independent aspect of the present disclosure, a revolving door with a sliding door function is proposed, as set out in claim 14, which revolving door is in particular designed to carry out a proposed method as described above or below, and which revolving door comprises the following: A door leaf assembly. The door leaf assembly comprises at least two door leaves with at least one sliding door element, and the sliding door element is drive-assisted such that a sliding door opening through the at least two door leaves can be opened and closed with motor assistance in a sliding door mode.

At least one sensor for detecting the movement of people in a detection area in front of and / or inside the revolving door. A data processing device configured to carry out the proposed method described above and below.

[0049] The proposed method described above can be implemented using this revolving door, in accordance with all the variants described above. The data processing device can be a microcontroller, a computer, a computer network, or any other data processing device. In particular, the data processing device can also be located remotely from the revolving door housing and communicate with the revolving door housing and associated drives and / or sensors via data cable and / or wirelessly.

[0050] According to a further independent aspect of the present disclosure, a computer program product for operating a revolving door with a sliding door function is proposed, as described in claim 15. This computer program product comprises instructions that, when executed by a computer, cause the computer to perform the proposed method described above or below. The computer program product can, in particular, be executed by the data processing device of the revolving door described above. The computer program product can, as proposed, be configured to implement any variant of the proposed method described above or below. In particular, the computer program product comprises instructions that cause the proposed revolving door, as described above or below, to perform the process steps according to the proposed method, as described above or below.as described below.

[0051] Features described above or below, relating only to one type of subject matter of the invention, for example, only to a method for operating a revolving door, can be adapted in a technically meaningful way to the other subject matter of the claim, such as the revolving door itself, and form further proposed embodiments. In particular, the proposed revolving door or its components can be configured to perform the described process steps.

[0052] Preferably, the revolving door has exactly two door leaves (so-called double-leaf revolving door).

[0053] Further advantageous and preferred embodiments will become apparent from the following description with reference to the figures. The drawing, which merely depicts exemplary embodiments, shows: Fig. 1 a schematic representation of a proposed revolving door in a perspective view, Fig. 2 a schematic representation of the proposed revolving door in a top view at a first time point according to a first scenario, Fig. 3 a schematic representation of the proposed revolving door in a top view at a second time point according to the first scenario, Fig. 4 a schematic representation of the proposed revolving door in a top view at a third time point according to the first scenario, Fig. 5 a schematic representation of the proposed revolving door in a top view at a fourth time point according to the first scenario, Fig. 6 a schematic representation of the proposed revolving door in a top view at a fifth time point according to the first scenario, Fig.Fig. 7 shows a schematic representation of the proposed revolving door in a top view at a sixth time point according to the first scenario; Fig. 8 shows a schematic representation of the proposed revolving door in a top view at a seventh time point according to the first scenario; Fig. 9 shows a schematic representation of the proposed revolving door in a top view at an eighth time point according to the first scenario; Fig. 10 shows a schematic representation of the proposed revolving door in a top view according to a second scenario; Fig. 11 shows a schematic representation of the proposed revolving door in a top view according to a third scenario; and Fig. 12 shows a flowchart of the proposed procedure.

[0054] Fig. 1 Figure 1 shows a schematic representation of a proposed revolving door 1 in a perspective view. The revolving door 1 is a fully automatic revolving door 1 that requires no action from the person passing through it, such as an additional push. The revolving door 1 has two door leaves 2. Each door leaf 2 has a sliding door element 3 that can be opened by a motor (not shown). The door leaves 2 together form a door leaf assembly 4, which in principle allows passage through the revolving door 1 in two different ways. Firstly, a central passage through the door leaves 2, or through the door leaf assembly 4, can be opened and closed as a sliding door passage ST by opening the two sliding door elements 3 laterally (in Fig. 1 The sliding door passage ST is closed; see also below. Fig. 6 ), specifically when the revolving door 1 is in sliding door mode. Furthermore, the door leaf assembly 4 is rotatable by a drive (not shown) about a virtual central axis, a vertical axis (not shown separately), specifically, in principle along both circumferential directions u, but in the present and preferably configuration along the direction of rotation v, which corresponds to the clockwise direction in a top view (see also Fig. 4 The door leaf assembly 4 is guided in an outer ring and can be driven via this ring, so that the door leaves 2 can be set into a rotary motion when the revolving door 1 is not in sliding door mode but in the rotation operating state. The sliding door function in question can, in principle, be implemented in the sliding door mode in the manner of a conventional sliding door, so that the sliding door opening ST can also be closed in sliding door mode (as in Fig. 1 (as shown above), so that a sliding door closing state exists, or the sliding door opening ST is opened by moving the sliding door elements 3 laterally, so that a sliding door opening state exists, whereupon the sliding door closing state can be entered again by closing the sliding door elements 3 again, without having to leave the sliding door mode (and switch back to the rotation operating state).

[0055] The revolving door 1 can be entered through a front access opening 5, which opens, for example, to an exterior building 6, and exited through a rear access opening 5, which opens, for example, to an interior building 7. It is understood that the revolving door 1 can be traversed in both directions. A sensor D6 is mounted on a housing 8 of the revolving door 1 above the front access opening 5. In this case, the sensor D6 combines a camera and a lidar sensor. With the aid of this sensor D6, an area in front of the access opening 5, specifically a detection area E6 assigned to the sensor D6 (see Figure 1), can be monitored. Fig. 2 ). are recorded. Sensor D6 therefore monitors the building exterior 6, while the sensor on the other side of an exterior wall 9 (in Fig. 1 The base of the outer wall is indicated by dashed and hatched lines; see also Fig. 2 bis Fig. 11 The interior side of the building 7 is monitored by a further, appropriately designed sensor. This sensor, or potentially other sensors not shown, of the revolving door 1 are arranged within the housing 8 of the revolving door 1 and above the rear access opening 5 of the revolving door 1 in order to monitor further detection areas 10 with regard to the movement of people.

[0056] The direction of rotation v generally points in the Fig. 1 bis 11 The present revolving door 1, viewed from above, can be set into a clockwise rotational movement by means of its rotary drive. Rotation in the opposite direction is also possible and conceivable, but the default state is that in the rotational operating state of the illustrated revolving door 1, the direction of rotation v is clockwise, "right-hand," and thus, when people pass through, it is a left-hand traffic flow.

[0057] Fig. 2 Figure 1 shows a schematic representation of the proposed revolving door 1 in a top view at a first point in time according to a first scenario. The roof of the revolving door 1 is not shown, thus providing a direct top view of elements within the housing 8 of the revolving door 1. The two door leaves 2, which form the door leaf assembly 4 of the revolving door 1, are arranged within the housing 8. Locking elements 11 are arranged laterally on the outer edges of each door leaf 2. These locking elements, along with the door leaf 2, can be rotated into the area of ​​the access openings 5, for example, to block the access openings 5 ​​to the revolving door 1 at night. Furthermore, the locking elements 11 and the resulting widened outer edges of the door leaves 2 ensure that, regardless of the angle of the revolving door 1, the access openings 5 ​​to the revolving door 1 remain open.The door leaf 2 in the rotational operating state of the revolving door 1 never forms a continuous open connection between the inside of the building 7 and the outside of the building 6, which could result in an undesirable draft phenomenon and thus an energy loss due to heating or cooling losses.

[0058] In addition, a display case glass 12 is provided on each door leaf 2, so that a display case area is formed between the door leaf 2, the locking element 11 and the display case glass 12, in which, for example, exhibition objects can be placed.

[0059] The sensors D6 and others of the revolving door 1 detect a detection area E6 or 10 in front of the two access openings 5 ​​and inside the housing 8 of the revolving door 1. The entire detection area D6 and 10 is formed by three non-contiguous areas, the respective boundaries of which are marked by dashed lines.

[0060] Fig. 3 shows a schematic representation of the proposed revolving door 1 from Fig. 2 in a top-down view at a second point in time according to the first scenario. The second point in time is chronologically after the first. The revolving door 1 has a rotary drive for moving the door leaves 2 and is in a fully automatic operating mode, so that the door leaves 2 have rotated further with drive assistance compared to the first point in time. The revolving door 1 is in the rotation operating state as well as still in the sliding door closing state, in which the sliding door passage ST is blocked due to the closed position of the sliding door elements 3. It now appears in the Fig. 3 In the situation shown, a group of people 13 are standing in front of the lower (front) access opening 5 of the revolving door 1.

[0061] The group of persons 13 is identified by the sensor D5 located above the front access opening 5 (in Fig. 3 (not shown) the revolving door 1 is monitored. The collected sensor data is forwarded to a data processing unit of the revolving door 1. The data processing unit evaluates the sensor data as part of an initial analysis. During this initial analysis, the data processing unit determines that the group of people 13 is approaching and that its size exceeds a predefined threshold of eight people. Furthermore, based on the direction of movement of the group of people 13, illustrated here by a symbolic arrow 14, the data processing unit determines that the group of people 13 is moving towards the front access opening 5 of the revolving door 1. The data processing unit also determines the speed of movement of the group of people 13.For this purpose, an average movement speed averaged over all persons in group 13 can be used as a reference, or, for example, the slowest movement speed of the slowest person in group 13.

[0062] Based on the initial analysis, the data processing device determines that the revolving door 1 should switch to sliding door mode, and furthermore, specifically that the door leaves 2 should be opened by moving or shifting the sliding door elements 3 so that the group of people 13 can pass through the revolving door 1 more quickly than in the rotational operating state. The revolving door 1 should therefore first switch to sliding door mode and then also to a sliding door open state. Otherwise, a bottleneck could occur due to the size of the group of people 13. Since the group of people 13 is approaching relatively quickly, the data processing device further determines that the switch to sliding door mode should begin immediately.

[0063] Fig. 4 shows a schematic representation of the proposed revolving door 1 from Fig. 2 or 3 in a top view at a third point in time according to the first scenario. The third point in time is after the second point in time. The group of people 13 has moved further towards the revolving door 1 and has also grown in size. In order to ultimately switch to the sliding door open state, the door leaf arrangement 4 should first assume the most suitable, so-called rotational desired position. This is shown in the illustration according to Fig. 4 not yet reached, so the door leaf arrangement 4 continues to be driven in the direction of rotation v by the rotary drive.

[0064] Fig. 5 shows a schematic representation of the proposed revolving door 1 from Fig. 2 or 3 or 4 in a top view at a fourth point in time according to the first scenario. The fourth point in time is chronologically after the third point in time. The door leaf assembly 4 has now reached the desired rotational position, which, in the case of the present double-leaf revolving door 1, is the 0° position, in which the door leaves 2 run parallel to the access openings 5. The door leaves 2 are essentially aligned parallel to the access openings 5 ​​of the revolving door 1 and the outer wall 9. In this position, the drive stops the rotational movement of the door leaf assembly 4. The switch to the sliding door opening state can now take place. In principle, however, it is also conceivable that the opening of the sliding door passage ST could begin shortly before the desired rotational position is reached.

[0065] Fig. 6 shows a schematic representation of the proposed revolving door 1 from Fig. 2 or 3, 4, or 5 in a top-down view at a fifth point in time according to the first scenario. The fifth point in time is chronologically after the fourth point in time. Since the door leaf assembly 4 is now in the desired rotational position, the data processing device controls the sliding door drive(s) or the displacement drive(s) of the revolving door 1, which is / are assigned to the sliding door elements 3. The sliding door elements 3 are thereby displaced laterally or moved open, with the respective direction of movement of the sliding door elements 3 being indicated by symbolic displacement arrows 15.

[0066] Fig. 7 shows a schematic representation of the proposed revolving door 1 from Fig. 2 or 3, 4, 5, or 6 in a top-down view at a sixth point in time according to the first scenario. The sixth point in time occurs after the fifth point in time. Now, a sliding door passage ST is fully open through the door leaf arrangement 4, and the group of people 13 passes through it. The revolving door 1 has already assumed the sliding door open state in the representation.

[0067] Fig. 8 shows a schematic representation of the proposed revolving door 1 from Fig. 2 or 3, 4, 5, 6, or 7 in a top-down view at a seventh time point according to the first scenario. The seventh time point occurs after the sixth time point. Now, the group of people 13 has largely passed through revolving door 1, and no further people are approaching from the outside of the building 6. Meanwhile, sensors D6 and others of revolving door 1 continue to monitor detection area E6 or 10. The data processing device of revolving door 1 performs a second analysis based on the recorded sensor data. The second analysis shows that only a small number of people remain in detection area 10 of revolving door 1, and that these people are moving away from revolving door 1. Based on this, the data processing device determines that the sliding door passage ST should be closed and thus the sliding door should be closed.It controls the sliding door drives so that the sliding door opening ST is closed by closing or shifting the sliding door elements 3. This is indicated by symbolic shift arrows 15. In principle, it would also be conceivable for the sliding door to close automatically, for example, due to the lack of detection of other people attempting to pass through the revolving door 1 in sliding door mode. In principle, the revolving door 1 could continue to operate in sliding door mode. However, based on the second analysis, it is determined that the revolving door 1 should switch back to its rotational operating state.

[0068] The second analysis mentioned here doesn't necessarily have to be the second analysis, and therefore the first subsequent analysis of sensor data after the first. Rather, the terms "first" and "second" in this context serve to distinguish that the analyses have different purposes or effects. The first analysis determines whether to switch to sliding door mode, while the second analysis determines whether to switch back from sliding door mode to rotation mode, or whether to continue operating the revolving door 1 in sliding door mode. Therefore, many subsequent analyses can, of course, follow an initial analysis and correspond to the same type of analysis until a switch to sliding door mode is required.The sliding door opening state may continue to be performed, so that the next or further analysis(s) is (or possibly many further) a "second analysis(s)".

[0069] Fig. 9 shows a schematic representation of the proposed revolving door 1 from Fig. 2 or 3, 4, 5, 6, 7, or 8 in a top-down view at an eighth point in time according to the first scenario. The eighth point in time occurs after the seventh point in time. The sliding door elements 3 are now fully closed and thus in the closed position, closing the door leaf assembly 4. The revolving door 1 has also now returned to its rotational operating state. To allow arriving persons to pass through the revolving door 1 in the future, the rotation drive subsequently begins to set the door leaf assembly 4 back into rotation.

[0070] Fig. 10 Figure 1 shows a schematic representation of the proposed revolving door 1 in a top view according to a second scenario. The roof of the revolving door 1 is again not shown, so elements inside the door are visible. According to the second scenario, a wheelchair user 16 approaches the revolving door 1. The wheelchair user 16 is moving at a slow speed. The wheelchair user 16 is moving slower than, or too slowly for, the fully automatically rotating door leaves 2 of the revolving door 1. The wheelchair user 16 would therefore not be able to pass through the revolving door 1 in its rotating operating state. The speed of the wheelchair user 16 is below a threshold value, which is detected during an initial analysis by the data processing device of the revolving door 1.Thus, the data processing device of the revolving door 1 controls the sliding door drives in such a way that the sliding door elements 3 are moved into the sliding door open state, which is again indicated by symbolic displacement arrows 15. Based on the initial analysis, the revolving door 1 was therefore switched from its rotational operating state to its sliding door mode.

[0071] Fig. 11 Figure 1 shows a schematic representation of the proposed revolving door 1 in a top view according to a third scenario. The roof of the revolving door 1 is again not shown, so elements inside the door are visible. According to the third scenario, two people 17 approach the revolving door 1, carrying a bulky object 18. In an initial analysis, the data processing device of the revolving door 1 processes sensor data from the detection area D6 or 10 of the revolving door 1. It determines the dimensions of the object. The data processing device further determines that the dimensions of the object 18 exceed predefined limits. The object 18 cannot be transported through the revolving door 1 in its rotating operating state.Thus, the data processing device of the revolving door 1 controls the sliding door drives in such a way that the sliding door elements 3 are moved into the sliding door open state, which is again indicated by symbolic displacement arrows 15. Based on the initial analysis, the revolving door 1 was therefore switched from its rotational operating state to its sliding door mode.

[0072] Fig. 12 Figure 1 shows a flowchart of the proposed procedure. This begins in step S100 with the acquisition of initial sensor data by a sensor or the receipt of this initial sensor data by a data processing device of a revolving door. At this point, the revolving door is in a rotational operating state and also in a sliding door closing state, in which one door leaf assembly of the revolving door is closed by sliding door elements of the door leaf assembly. In step S200, the data processing device performs an initial analysis of the initial sensor data. In step S300, based on this initial analysis, the data processing device determines that the revolving door should switch to a sliding door mode and, more specifically, that a sliding door opening of the revolving door should be opened.In a fourth step, S400, the data processing device controls a rotary drive of the revolving door, which is coupled to a door leaf assembly of the revolving door, such that the door leaf assembly assumes a predefined desired position. In a fifth step, S500, the data processing device controls the sliding door drives of the revolving door so that the sliding door opening is opened by moving the sliding door elements upwards or downwards. Thus, the revolving door assumes a sliding door open state.

[0073] In step six, S600, the door leaf assembly is in the sliding door open position. The data processing device then performs a second analysis based on two sensor readings. In step seven, S700, the data processing device determines that the sliding door opening should be closed. In step eight, S800, the data processing device controls the sliding door drives of the revolving door so that the sliding door opening is closed by closing or moving the sliding door element. The revolving door thus returns to the sliding door closed position. Furthermore, based on the second analysis, the revolving door also switches back to the rotation operating state.It could also be intended that the second analysis serves only to determine whether the revolving door should switch back to the rotational operating state, while the described steps of closing the sliding door opening and thus resuming the sliding door closed state occur completely automatically without any special analysis of sensor data. In this way, the revolving door can also be operated in its sliding door mode like a conventional sliding door, allowing arriving persons to pass through by opening the sliding door opening based on simple detection, and then closing that sliding door opening again without automatically switching back to the rotational operating state. Instead, it continues to operate in the sliding door mode until a switch back to the rotational operating state is desired and either actively selected or performed automatically based on the aforementioned second analysis.
