Description

[0001] The present invention relates to a method for operating a fully automatic revolving door, a fully automatic revolving door and a computer program product that can be used to operate the fully automatic revolving door.

[0002] In the field of revolving doors, sometimes also called rotating doors, three different types are generally common. Firstly, there are revolving doors that require the cooperation of the person passing through and are operated either fully manually by the person pushing, or semi-automatically by means of a drive and additional pushing by the person passing through. These two types of revolving doors are not the subject of this disclosure. Secondly, there are also revolving doors that are operated fully automatically, without requiring any manual pushing by the person passing through. Such doors, which are the subject of this disclosure, are referred to here as fully automatic revolving doors, or can generally also be called "full-energy revolving doors."

[0003] Fully automatic revolving doors are subject to special requirements. It is generally desirable to minimize energy consumption and prevent unnecessary door rotations, such as those that are not used. Furthermore, it is desirable to minimize air exchange and any associated heat loss between the two sides of the door, typically the interior and exterior of the building. For this purpose, fully automatic revolving doors can be set to a default position in which the door leaves are stationary and the door does not rotate. In the specific case of a double-leaf revolving door, this stationary position typically results in the access opening being defined by the (widened or extended with additional elements) outer edge of the door leaf.The two opposing access openings are completely or at least partially blocked by the two existing outer edges of the door leaves. Even with revolving doors with more than two leaves, the problem can arise that the outer edges of the door leaves obstruct the open, theoretically accessible area of ​​the revolving door's access opening. However, these circumstances can fundamentally hinder comfortable and, in particular, seamless passage for people through fully automatic revolving doors, or access to the interior of the revolving door, because an outer edge in the access opening can obviously obstruct access to the interior of the revolving door and thus passage through it.Furthermore, a poorly chosen starting sequence for the actual motor assistance required for passage through the revolving door can be particularly critical for a smooth passage. If, for example, the starting sequence begins too late, while the approaching person intending to enter is only a short distance from the door leaf, they may mistakenly conclude that it is not a fully automatic revolving door, but rather that they need to provide assistance or even push it. If, however, the person then actually reaches for and touches the door leaf of a fully automatic revolving door, this usually leads to a stop or interruption of the automatic rotation of the door leaves for safety reasons. This results in unnecessary delays for people passing through the revolving door.Should the starting process of any acceleration or deceleration to the "transit rotation speed" of the door leaves required for passage be fundamentally unfavorable, it may adversely occur that, especially when a person arrives wishing to enter, the outer edge of a door leaf is positioned disruptively in the access opening, necessitating unnecessary deceleration and waiting of the person.

[0004] Against this background, it is an object of the present invention to provide a method for operating a fully automatic revolving door, as well as a fully automatic revolving door and a corresponding computer program product, with which at least one of the problems described above is addressed. In particular, it is an object to make the passage through the revolving door as smooth and seamless as possible for approaching persons wishing to enter, while simultaneously minimizing energy loss, whether through unwanted heat exchange between the two sides of the door or through unnecessary acceleration or deceleration.

[0005] This problem is solved with respect to a method by the method for operating a fully automatic revolving door with the features of claim 1, with respect to a fully automatic revolving door by the fully automatic revolving door with the features of claim 13, and with respect to a computer program product by the computer program product according to claim 15. Advantageous embodiments are the subject of the dependent claims and the following description.

[0006] The central finding here is that, through sensor-based detection of people's movements and targeted application of the acquired sensor data, the opening angle of the revolving door can be optimized for approaching individuals. As proposed, it is thus possible to precisely control the rotation of the door leaves, reducing the risk of a person walking towards the outer edge of a door leaf. Furthermore, the rotation can be selectively accelerated or decelerated to ensure the smoothest possible passage (also for subsequent users) and / or to optimize energy consumption. The present invention thus improves a fully automatic revolving door by optimizing it through the use of sensors to automatically set a desired opening angle as a predetermined access angle or a desired rotation angle of the door leaves when a person is expected to approach the revolving door.This technology allows people to enter the revolving door area seamlessly and without any deceleration upon arrival, without being hindered by the outer edge of a door leaf. The proposed procedure and revolving door design ensure that the passage through the door is as smooth and seamless as possible for approaching individuals, while simultaneously minimizing energy loss. This is achieved through precise control of the door leaves, based on the detection of people's movements. This control accelerates the door leaves so that the access area of ​​the revolving door opening has a predetermined opening angle at the anticipated arrival time of the person.

[0007] Specifically, according to a first independent aspect of the disclosure, as set forth in claim 1, a method for operating a fully automatic revolving door is proposed, which method comprises at least the following steps a) to d): a) Providing a revolving door with at least two door leaves, a drive unit, and at least one sensor for detecting pedestrian movement, wherein the drive unit is configured to rotate the at least two door leaves within a passage area of ​​the revolving door. b) Detecting the speed and direction of approach of at least one person approaching the revolving door from an approach side using the at least one sensor. c) Calculating an estimated arrival time of the person at the revolving door based on the detected speed and direction of approach. d) Accelerating the at least two door leaves by the drive unit such that an access area of ​​an entry opening of the revolving door has a predetermined opening angle at the estimated arrival time of the person.

[0008] The term "fully automatic revolving door" refers to a revolving door that is entirely motorized and does not require any manual pushing by a person for its intended use; in fact, manual pushing is strictly prohibited and must be prevented. A "drive" is a mechanical device that sets the revolving door leaves in rotation. "Sensors" are devices that detect the movements and / or positions of people. The "passage area" of the revolving door is the area through which people can pass. Due to the rotation of the revolving door, the passage area is variable and continuously adjusted. A person enters the interior of the revolving door, which encompasses or provides the passage area, via the "access area."The access area is also variable because an outer edge of a door leaf can temporarily partially obscure the access area, thus dividing it into two parts, or can even partially obscure it completely in a specific position (for example, in the case of a double-leaf revolving door with widened outer edges). Basically, a revolving door has an "access opening" (or two opposing access openings), which is either fully 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 is divided (or even completely covered) by an outer edge of a door leaf, so that the person can only enter the passage area of ​​the revolving door (and thus their interior area) through the access opening to the left or right of the door leaf, and thus through either the left or the right resulting access area.

[0009] One advantage of this method is the optimization of the opening angle of the door leaves available for entry, ensuring natural and smooth movement through the door. This angle, which is the opening angle into which a person approaching the revolving door can freely walk without colliding with the outer edge of a door leaf, is also called the walking opening angle. In this context, it is stated that the access area of ​​the entrance opening has precisely this walking opening angle. In a case of, for example, 30°, this means that the outer edge of the door leaf, or rather the leading portion of this outer edge when viewed in the direction of rotation, and the leading edge of the entrance opening when viewed in the direction of rotation (i.e., the right-hand edge in a revolving door rotating counterclockwise when viewed from above) enclose such an angle of 30°.This definition of the access opening angle can also refer to the access opening angle in front of a door leaf, as it describes the access area within the revolving door's interior, located in front of the door leaf in the direction of rotation. Alternatively, an access opening angle can, of course, also be formed behind the door leaf or used by the approaching person. This is then formed directly behind a door leaf and the closing edge of the access opening, which is also located behind this door leaf in the direction of rotation. A further advantage can be energy savings through a possible minimization of the time required for full motor assistance and by minimizing unnecessary braking and acceleration processes.

[0010] Furthermore, the air and heat exchange between the inside and outside of the building can be reduced if there are unnecessary and avoidable unused openings.

[0011] A revolving door typically has two or more leaves that rotate within a circular housing. The leaves can be mounted on and driven by a rotating central axis. Revolving doors offer the fundamental advantage of restricting the ingress of outside air into a building, thus contributing to energy savings. They have access points in the form of openings on both the inside and outside of a building (or on the two corresponding opposite sides of the building areas separated by the revolving door).

[0012] The proposed precise control ensures that the door leaves are in an optimal or desired position when the person reaches the revolving door, resulting in a seamless and comfortable passage. The invention thus offers an improved solution for the operation of fully automatic revolving doors, increasing user comfort and contributing to energy savings, as the rotation can be adapted to the optimal use of the revolving door, thereby reducing the number of unused rotations and the duration of unnecessary open positions.

[0013] In particular, the drive accelerates the at least two door leaves in such a way that the access area of ​​an entry opening of the revolving door reaches a predetermined opening angle at the person's expected arrival time, with the acceleration being based on the detected speed and approach direction of the person. Specifically, the acceleration is controlled by a control unit that processes the detected data on the person's speed and approach direction.

[0014] In particular, the acceleration of the at least two door leaves by the drive is such that an access area of ​​an entry opening of the revolving door has a predetermined opening angle for walking at the presumed arrival time of the person, and that no outer edge of a door leaf blocks, divides or completely covers the access area, and the person can enter unhindered.

[0015] In particular, the predetermined opening angle for passage is defined in such a way that the person can pass through the access area or the open entry opening without obstruction by an outer edge of a door leaf.

[0016] In particular, the moment or time of entry by the person is chosen in such a way that the door leaves are in a comfortable position, or that the person does not have to wait for an outer edge of a door leaf to pass in order to enter the interior of the revolving door.

[0017] The proposed revolving door and its corresponding operating procedure allow for various types of revolving doors. Firstly, double-leaf revolving doors, where two door leaves run in a straight line and form an angle of 180°, can be used. Secondly, triple-leaf revolving doors, where each of the three door leaves forms an angle of 120° to each other, and finally, quadruple-leaf revolving doors, where each of the four door leaves forms an angle of 90° to each other, are also possible.

[0018] Depending on the specific type of revolving door, different maximum opening angles are possible for the access area. For example, a double-leaf revolving door can have a maximum opening angle of 60°, which is available over a longer rotation range. A triple-leaf revolving door can also have a maximum opening angle of 60°, but over a shorter rotation range. A four-leaf revolving door can have a maximum opening angle of 90°.

[0019] As proposed, these different maximum opening angles, depending on the revolving door type, are used to optimally control the pedestrian opening angle of the revolving door. The pedestrian opening angle is the angle that the access area of ​​the revolving door's entry opening has at the anticipated arrival time of a person, i.e., when they are passing through the entry opening. This angle is chosen so that the person can enter unhindered without walking towards the outer edge of a door leaf.

[0020] Preferably, specific angular ranges can be set for the pedestrian opening angle. For a double-leaf revolving door, the preferred pedestrian opening angle can be, for example, between 45° and 60°, particularly preferably between 50° and 60°, and more preferably between 55° and 60° (either in front of or behind the door leaf in the direction of rotation), or more preferably substantially 60°. For a three-leaf revolving door, the preferred pedestrian opening angle can be between 30° and 60°, particularly preferably between 45° and 60°, and more preferably between 55° and 60° (either in front of or behind the door leaf in the direction of rotation), or more preferably substantially 60°.In the case of a four-leaf revolving door, the preferred opening angle for passage can be between 55° and 90°, particularly preferably between 75° and 90°, and more preferably between 80° and 90° (either in front of or behind the door leaf in the direction of rotation), or more preferably substantially 90°. These angle ranges ensure that the access area of ​​the revolving door's opening is sufficiently or optimally open at the anticipated arrival time of the person to allow seamless passage.

[0021] In particular, the predetermined walking opening angle is selected depending on the number of door leaves of the revolving door, whereby the predetermined walking opening angle (in the direction of rotation either in front of the door leaf or behind the door leaf): between 45° and 60°, preferably substantially 60°, for a two-leaf revolving door; or between 30° and 60°, preferably substantially 60°, for a three-leaf revolving door; or between 55° and 90°, preferably substantially 90°, for a four-leaf revolving door.

[0022] According to a further embodiment of the method for operating a fully automatic revolving door, the revolving door is configured, in step d), to accelerate the at least two door leaves to a passage rotation speed according to the following operating operations: The at least two door leaves are accelerated from a standstill to the passage rotation speed, accelerated from a lower base rotation speed or a lower preceding passage speed to the passage rotation speed, or decelerated from a higher preceding passage speed to the passage rotation speed. These operating operations ensure that the door leaves always rotate at the optimal speed to allow seamless passage for the person.It may also be possible to perform several acceleration or deceleration maneuvers while a person approaches the carousel door, in order to then allow the person to enter as seamlessly as possible upon arrival.

[0023] In particular, the rotational speed can be the speed that exists when the person arrives at the revolving door or when the person passes through the revolving door.

[0024] Preferably, the estimated arrival time of the person at the revolving door can also be calculated multiple times and the control signals for accelerating the door leaves according to step d) can be corrected or adjusted based on the multiple calculations.

[0025] A further step in the process involves determining the rotational speed of one or more of the door leaves based on the detected speed of the person, in order to enable seamless passage through the revolving door. By adjusting the rotational speed of the door leaves, a smooth and comfortable passage through the revolving door can be ensured. Essentially, passage without any braking is possible. A smooth passage for the person can be facilitated. This adjustment can be made to the detected speed of the person's movement.

[0026] According to a further embodiment, a desired access position of the at least two door leaves is preset in such a way that in the desired access position no outer edge of the at least two door leaves divides or covers the access area of ​​the access opening of the revolving door.

[0027] Preferably, an outer edge of one of the at least two door leaves, viewed in the direction of rotation, can be positioned at an angle of up to 15°, preferably up to 5°, in front of, and preferably directly in front of, the access opening when viewed in the desired access position. These pre-settings ensure that the person can enter without hindrance.

[0028] Preferably, the starting time of the acceleration of the at least two door leaves (in particular to the passage rotation speed) and / or the magnitude of the passage rotation speed of the at least two door leaves is determined such that the at least two door leaves are in the desired access position at the presumed arrival time of the person at the revolving door. This ensures that the door leaves are in the optimal position at the right time to allow seamless passage.

[0029] The revolving door can be configured with an initial automatic operating mode in which at least two door leaves remain stationary in a default position. In this mode, the revolving door stays in a resting position until the sensors detect a person approaching. This means the door leaves do not rotate continuously but are only activated when someone approaches and wants to pass through. The advantage of this initial automatic operating mode is energy savings, as the drive is only activated when needed, instead of running continuously. This significantly reduces energy consumption and contributes to sustainability. Furthermore, this mode minimizes air exchange between the interior and exterior of the building, which is particularly beneficial in air-conditioned environments, as it reduces heat loss.Another advantage is the reduced wear and tear on the revolving door's mechanical components, as these are not constantly in motion but are only activated when needed. This extends the door's lifespan and reduces maintenance costs. Furthermore, the stationary state of the door leaves offers increased safety, as they do not rotate uncontrollably, thus minimizing the risk of accidents or injuries.

[0030] Alternatively, the revolving door can be configured for a second automatic operating mode. In this mode, the drive unit rotates the at least two door leaves at a lower base speed, then accelerates them to a speed suitable for pedestrian passage, and after the person has passed, decelerates them back to the lower base speed and continues rotating at that speed. This second automatic operating mode ensures that the door leaves remain in continuous motion. This can be particularly advantageous in high-traffic areas such as shopping centers, airports, or office buildings where a constant flow of people is expected.On the other hand, the basic, continuous rotation at low speed can help optimize the drive's energy consumption, as the door leaves do not constantly need to be accelerated from a standstill, which typically requires more energy. Furthermore, this operating mode can also extend the service life of the revolving door's mechanical components, as the stress caused by frequent starting and stopping is reduced. In this context, "low rotation speed" means that it is lower than the rotation speed generated by the drive in a typical, normal passing situation, when a person wants to pass through the revolving door.Accordingly, the torque provided by the drive in the second automatic operating mode is lower than the torque provided by the drive when a person walks through the revolving door normally. An exception may occur if a very slow rotational speed is deliberately set, even when, for example, a disabled or very slow-walking person passes through.

[0031] According to a further embodiment, the revolving door has a sensor system that monitors both the approach side and an exit side of the revolving door opposite the approach side. Preferably, the sensor system comprises at least one sensor for monitoring the approach side and at least one further, in particular similar, sensor for monitoring the exit side.

[0032] In principle, at least one sensor can be, for example, a radar sensor and / or a lidar sensor. These specific sensor types offer a precise and reliable method for detecting people's movements, which is crucial for optimizing door control. Radar sensors use electromagnetic waves to measure the distance, speed, and direction of objects, while lidar sensors use light pulses to capture accurate three-dimensional information about the environment. By integrating these sensor technologies, the revolving door can detect a person's approach speed and direction with high accuracy. One advantage of using radar sensors is their ability to operate independently of lighting conditions and weather, making them particularly reliable in diverse environments.Lidar sensors, on the other hand, can offer high resolution and accuracy in detecting distances and movements, which can improve the detection and tracking of people's movements.

[0033] In principle, the applicant's MotionIQ technology can also be used to support the tasks of capturing or processing sensor data.

[0034] In particular, the method can include determining whether at least one person intends to pass through the revolving door, preferably by evaluating the body orientation, posture (especially sitting or lying positions), facial expressions, gestures, and / or gaze direction of that person. Specifically, a person for whom a desire to pass through has been determined can be weighted differently when evaluating the recorded movements of people than a person for whom no desire to pass through has been determined. Reference can also be made to the European patent application EP4095341A1, filed by the present applicant, the contents of which are incorporated herein by reference.The expert can glean basic information from this registration regarding door control and the detection of person movements, as well as inferences regarding access requests.

[0035] In particular, an initial analysis of the recorded person movements can be carried out in such a way that the initial analysis includes a detection of 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 that falls below a predefined threshold.

[0036] In particular, the proposed method can include the following further step: decelerating the at least two door leaves from their rotational speed during passage to a standstill or to a lower base rotational speed after a person has passed through the revolving door. Preferably, the at least two door leaves come to a standstill in such a way that the drive automatically rotates them into a desired, further rotated stopping position, wherein, in the desired, further rotated stopping position, no outer edge of the at least two door leaves divides or obscures the access area of ​​the revolving door's entrance opening. The desired, further rotated stopping position can be the desired entry position.

[0037] According to a further embodiment, the revolving door has at least one additional auxiliary sensor, preferably for monitoring the exit side of the revolving door opposite the approach side. This additional auxiliary sensor preferably detects only the presence of a person passing through the passage area of ​​the revolving door and exiting accordingly. The detected presence of the person on the exit side is used to initiate the braking of the at least two door leaves, in particular to a standstill or to a lower base rotational speed. The integration of this additional auxiliary sensor optimizes the detection of people's movements by precisely monitoring not only their approach but also their exit from the revolving door.This allows for improved control of the motorized drive by optimally supporting the rotation of the door leaves not only when a person approaches but also when exiting the revolving door, stopping the movement or slowing it down to slower, energy-saving speeds if necessary. One advantage of this additional monitoring is increased door control efficiency, as the motorized support is only activated when actually needed, leading to reduced energy consumption. Furthermore, air exchange between the interior and exterior can be minimized, which in turn reduces heat exchange and thus contributes to better energy efficiency for the building.

[0038] Auxiliary sensors can also be provided on both sides. In principle, depending on the perspective or the passage of people from one or the opposite side, both sides can represent an approach side or an opposite exit side.

[0039] In principle, the auxiliary sensor(s), as well as the (main) sensor for detecting people's movements, and even several of these (main) sensors, can each be a radar sensor or a lidar sensor. Such sensors are capable of capturing precise movement data and transmitting it to the revolving door's control unit. It is also possible for the (main) sensor to function as the primary sensor on each side (approach side and exit side) when viewed from the approach side, and as an auxiliary sensor when passing through the revolving door from the other side. Camera monitoring, control, or camera-based detection of people's movements is also conceivable, either as a primary or supplementary measure.

[0040] Specifically, the additional auxiliary sensor is intended to detect only the presence of a person passing through the revolving door's passage area and exiting on the exit side. In this case, the auxiliary sensor can only be positioned separately from the (main) sensor on that side. The use of such an additional auxiliary sensor, specifically designed to detect the presence of people passing through the revolving door's passage area and exiting on the exit side, can then be configured more efficiently, simply detecting the person's presence without measuring additional data such as speed or direction. Integrating this auxiliary sensor offers several advantages. First, it enables more precise control of the revolving door's drive by ensuring that the motor assistance ends precisely when the person leaves the passage area.This contributes to energy savings, as the drive remains active only as long as necessary for the smooth passage of the person. Secondly, this precise control minimizes air and heat exchange between the interior and exterior of the building, which is particularly beneficial in air-conditioned environments. The auxiliary sensor works in conjunction with the existing sensors that detect the approach speed and direction of the person, thus complementing the existing sensor system to ensure comprehensive monitoring of both the approach and exit sides of the revolving door. By detecting the presence of a person on the exit side, the system can determine the optimal time to stop the motor assistance, resulting in smoother operation of the revolving door.This not only improves the user experience by enabling smooth and intuitive movement through the door, but also reduces the mechanical stress on the door leaves and drive mechanism, thus extending the lifespan of the components. Overall, the introduction of the additional auxiliary sensor contributes to more efficient and user-friendly operation of the revolving door by optimizing the interaction between the various system components and reducing operating costs.

[0041] In particular, it is intended that the presence of a person on the exit side opposite the approach side of the revolving door, or the exit side itself, will be used to reduce or stop the rotational movement of the at least two door leaves by the drive.

[0042] In particular, it is provided that if a person intervenes, especially by touching the door leaves, a safety mode is activated and the passage rotation speed of the at least two door leaves is reduced, in particular the at least two door leaves are stopped.

[0043] A further step in the process involves detecting a group of people and controlling the rotation of at least two door leaves based on the slowest person approaching the revolving door within the group. This ensures that everyone in the group can pass through the revolving door safely and comfortably. However, it can also be configured that people moving too slowly, below a certain predefined threshold, are ignored and thus filtered out. In such cases, the control of the rotation might not be based on the objectively slowest person approaching the door, but rather on the slowest person who is still moving faster than the specified threshold.

[0044] According to another embodiment, the desired access position can be preset in different ways. For example, with a double-leaf revolving door, the 0° position can be preferred as the desired access position. This position can ensure a maximum opening width of 60°. Furthermore, the 0° position can provide a certain amount of free space in the passageway, so that people entering have room 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 another 45°. This allows subsequent people to enter the same passageway.

[0045] It may also be preferred if the desired entry position is variable. This variability can depend, in particular, on the sensor data collected. Furthermore, and preferably, the door leaves of the revolving door can be rotated so that the desired entry position is set at the anticipated arrival time of the person or the first person among several people.

[0046] The desired entry position can be adjusted depending on the number of people requesting access. Specifically, for a double-leaf revolving door, the 0° position can be set as the desired entry position for groups of up to two people. For groups of more than two people requesting access, the 45° position can be set as the desired entry position.

[0047] According to another independent aspect of the present disclosure, a fully automatic revolving door is proposed, as described in claim 13, which is configured in particular for carrying out a proposed method as described above or below. The proposed fully automatic revolving door comprises: at least two door leaves; a drive unit configured to rotate the at least two door leaves within a passage area of ​​the revolving door; at least one sensor for detecting person movements, wherein the at least one sensor is configured to detect the speed and direction of approach of at least one person approaching from an approach side of the revolving door; and a control unit configured to calculate an estimated time of arrival of the person at the revolving door based on the detected speed and direction of approach.

[0048] The control unit is proposed to accelerate at least two door leaves in such a way that an access area of ​​an entry opening of the revolving door has a predetermined opening angle for walking at the presumed arrival time of the person.

[0049] The proposed design may include the provision that the control unit is further configured to accelerate the at least two door leaves from a standstill, or a lower basic rotational speed, or a higher preceding passage speed to a passage rotational speed, and wherein the drive is configured to perform an automatic rotational movement of the at least two door leaves at the passage rotational speed.

[0050] Preferably, the revolving door has two door leaves (so-called double-leaf revolving door), or the revolving door has three door leaves (so-called triple-leaf revolving door), or the revolving door has four door leaves (so-called quadruple-leaf revolving door).

[0051] According to another independent aspect of the present disclosure, a computer program product is proposed, as described in claim 15, which computer program product comprises instructions that cause the proposed fully automatic revolving door, as described above and below, to execute the process steps according to the proposed method, as described above and below. The computer program product is configured to operate a proposed fully automatic revolving door, as described above and below.

[0052] Features described above or below, which may relate to only one type of subject matter of the invention, for example, only to a method for operating a fully automatic revolving door, can be adapted and transferred to the other subject matter of the claim, such as the fully automatic revolving door, in a technically meaningful way, and form further proposed embodiments. In particular, the proposed revolving door or its components can be configured to perform the described process steps. Features can also be transferred in a technically meaningful way between the subordinate, independent subject matter of the process or fully automatic revolving doors, each forming independent embodiments.

[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 is an isometric view of a four-leaf revolving door according to an embodiment; Fig. 2 a schematic top view of a four-leaf revolving door, namely according to view a) in a first position with people in the vicinity of the revolving door, and according to view b) in a second, further rotated position of the revolving door compared to the position according to view a); Fig. 3 a schematic top view of a three-leaf revolving door, namely according to view a) in a first position with people in the vicinity of the revolving door, and according to view b) in a second, further rotated position of the revolving door compared to the position according to view a); Fig. 4 a schematic top view of a two-leaf revolving door, namely according to view a) in a first position with people in the vicinity of the revolving door, and according to view b) in a second, further rotated position of the revolving door compared to the position according to view a); and Fig.5. A flowchart of a proposed procedure.

[0054] Fig. 1 Figure 1 shows an isometric view of a fully automatic revolving door 1. The revolving door 1 includes a turnstile 2. This turnstile 2 has four door leaves 3. The door leaves 3 are each angled at 90° to each other. The turnstile 2 is rotatable about an axis of rotation A. The axis of rotation A extends in the axial direction z. A radial direction r is defined perpendicular to the axial direction z. A circumferential direction u is defined about the axial direction z. The revolving door 1 can, in principle, be configured to rotate in both opposite directions with respect to the circumferential direction u. In the present embodiment, which is illustrated by the description of the figures, the revolving door 1 is configured to rotate counterclockwise when viewed from above (see direction of rotation v in Figure 1). Fig. 1 bis 4 ).

[0055] The revolving door 1 is usually installed in a wall 4 in the form of an exterior wall of a building, or in a wall separating two areas of a building (cf. Fig. 2 , Fig. 3 , Fig. 4 ) and provides a passage between an interior side 5 of the building and an exterior side 6 of the building (or the two building areas). For this purpose, the revolving door 1 provides an access opening 7 into its interior, whereby a person passing through the access opening 7 enters a passage area 7a and, as the door leaves 3 rotate along the direction of rotation v, the passage area 7a adjusts for the person entering until the person can leave the interior of the revolving door 1 on the other side (i.e., at the opposite access opening).

[0056] A drive 8 is arranged on the turnstile 2 for the automated rotation of the door leaves 3. This drive 8 can be designed as an electronically commutated multipole motor, with one rotor of this drive 8 being connected coaxially to the axis of rotation A of the turnstile 2. This allows the drive 8 to enable a direct and gearless drive of the turnstile 2.

[0057] As from Fig. 1 As can be seen, the access opening 7 is laterally bounded by the left end edge 9 and the right end edge 10 of the revolving door 1. An access area 11 for entering the interior of the revolving door 1 is generally bounded by these end edges 9 and 10, as well as by an upper end edge of the revolving door 1 and regularly by the floor at the bottom, and can extend to a maximum of the entire width of the access opening 7. However, this access area 11 is variable and can be partially obscured by an outer edge 12 of the door leaf(s) 3, or the outer edge 12 can divide the access area 11 into a left access area 11 and a right access area 11 in certain positions of the revolving door 1 or the door leaf(s) 3, as shown in the illustration. Fig. 1 and the corresponding position of the revolving door 1 is the case, and likewise in views b) of the Fig. 2 and Fig. 3 . In view b) of the Fig. 4 In the case of the double-leaf revolving door 1, the widened outer edges 12 of the two door leaves 3, created by extensions, completely block the two access openings 7 (one at the bottom, one at the top) in the illustrated position of the revolving door 1, thus no longer dividing them into left and right accessible access areas 11. All descriptions of the access area 11 on the exterior of the building 6 apply analogously to the opposite area on the interior of the building 5 and the access opening there, or the variable access area 11 formed there.

[0058] In principle, the variable access area 11 can be defined by the corresponding opening angle. According to view a) in Fig. 1 Four door leaves 3 are provided, such that an angle of 90° is enclosed between each pair of adjacent door leaves 3. The access opening 7 of this four-leaf revolving door 1 is selected to provide an access area 11 with a maximum opening angle of 90°. The resulting open access area 11 with the corresponding opening angle is shown in Fig. 2 In view a) it is indicated by the dashed lines and in that view it is also 90°.

[0059] Regarding the arrival of persons wishing to enter at carousel door 1, i.e., according to view a) in Fig. 2 Once persons P1 and P2 have passed the access opening 7, the opening angle available to them for passing through the access area 11 and thus through the access opening 7 can also be referred to as the walking opening angle α1. This walking opening angle α1 is defined between the front end of the outer edge 12 of the door leaf 3 (viewed in the direction of rotation v) and the front closing edge of the revolving door 1 (viewed in the direction of rotation v), in this case, the right closing edge 10. However, this only applies if a door leaf 3 is in a corresponding rotational position within the area of ​​the access opening 7 and not if there is no outer edge 12 present in the area of ​​the access opening 7. Then the two end edges 9, 10 simply define the current walking opening angle α 1 , which then corresponds to the maximum possible opening angle.

[0060] Based on the aforementioned definition of the pedestrian opening angle α1 as viewed in the direction of rotation v in front of a door leaf 3, this pedestrian opening angle α1 can therefore also be referred to as the pedestrian opening angle α1 in the direction of rotation v behind the door leaf 3. Alternatively or simultaneously (cf. e.g. Fig. 2 b) ) can of course also be formed as a pedestrian opening angle α 1 in the direction of rotation v in front of the door leaf 3 and be used by the person and can therefore also be referred to as such a pedestrian opening angle α 1 in the direction of rotation v in front of the door leaf 3.

[0061] For illustrative purposes, the situations described in views a) and b) are briefly discussed below. Fig. 2 bis 4 , and there, reference is made to the lower access opening 7: In view a) of the Fig. 2 The prevailing opening angle α is 90°; in view b) it is again 45° (specifically in the direction of rotation v both in front of and behind the door leaf 3). In view a) the Fig. 3 The prevailing opening angle α is 60°; in view b) it is again 30° (specifically in the direction of rotation v both in front of and behind the door leaf 3). In view a) the Fig. 4 The prevailing access opening angle α1 is 60°; in view b) it is 0°, since the outer edge 12 of the door leaf 3 blocks the access opening 7. Furthermore, the corresponding access opening angles α1 of the access openings shown above (which are not explicitly labeled) are the same as those of the lower access openings 7.

[0062] Fig. 2 Figure 1 shows a schematic top view of a four-leaf revolving door 1, specifically in view a) in a first position with persons P1, P2, P3 and P4 in the vicinity of the revolving door 1, and in view b) in a second position of the revolving door 1 rotated 45° further compared to the position in view a). In view a), the revolving door 1 is shown in the 0° position, where the access area 11 is maximally large, utilizes the entire available width of the access opening 7, and can be optimally used for entering the passage area 7a. In view b), the revolving door 1 is rotated a further 45°, providing two equally sized access areas 11, each with an opening angle of 45°, viewed once in the direction of rotation v in front of and once behind the door leaf 3, or the access opening 7 is divided into those two access areas 11 by the outer edge 12.

[0063] Similarly, in view b) the Fig. 2 to recognize how two equally sized access areas 11, each with an opening angle of 45° (see dashed lines), are provided, separated by the door leaf 3, which divides the access opening 7 in the middle in the illustration and the corresponding position of the revolving door 1.

[0064] Accordingly, the position can be determined according to view a) of Fig. 2 This can also be referred to as the 0° position of the four-leaf revolving door 1, whereby this 0° position is essentially the desired access position of the depicted revolving door 1. In this 0° position, the access area 11 is maximally large and can be optimally used by an arriving person P1 or P2 to enter the passageway 7a. In this desired access position, the 0° position, the four door leaves 3 are set so that their outer edges 12 do not extend into the access area 11 or the two access areas 11 of the access opening 7 of the revolving door 1 (or the two access openings 7, as shown in the illustration). Fig. 2 (above, another unmarked access opening is provided for access from the corresponding opposite side). Specifically, the outer edges 12 of the door leaves 3, viewed in the direction of rotation in the depicted desired access position, are arranged directly in front of and directly after the access area 11 of the access opening 7.

[0065] From the 0° position according to view a) of the Fig. 2 All subsequent positions of the four-leaf revolving door 1 can also be described if the door leaves 3 are rotated further in the direction of rotation v. Thus, the position according to view b) can be designated as the 45° position, and all intermediate positions on the way there as the 1° position, 2° position, etc. All positions following the 45° position according to view b) in the direction of rotation can be designated as the 46° position to the 89° position, because the apparent 90° position is again a new 0° position, corresponding to the position according to view a), except that the door leaf 3 previously (in view a)) arranged directly in front of the access area 11 of the access opening 7 now occupies a position as a door leaf arranged directly after the access area 11 of the access opening 7.

[0066] In the case of the three-leaf revolving door 1 according to Fig. 3 With three door leaves 3, two adjacent door leaves each enclose an angle of 120°. The access opening 7 is configured to provide a maximum opening angle of 60° for passage, and this 60° opening angle can now be provided over a longer rotation range. This shows Fig. 3 Figure 1 shows a schematic top view of a three-leaf revolving door 1, specifically in view a) in a first position with persons P1, P2, P3, and P4 in the vicinity of the revolving door, and in view b) in a second position of the revolving door rotated 30° further compared to the position in view a). View a) shows the desired access position of the three-leaf revolving door 1, which can be referred to as the 0° position. From this position to the position shown in view b), the door leaves 3 have been rotated 30° further. View b) shows the 30° position, with two smaller access areas 11, each with an opening angle of 15°, one in front of and one behind the door leaf 3 when viewed in the direction of rotation v.

[0067] From the desired access position of the three-leaf revolving door 1 according to view a) to the position shown in view b) of the Fig. 3 In the position shown, the door leaves 3 were rotated a further 30°, resulting in the 30° position, and two smaller access areas 11 were again formed, each with an opening angle of only 15°. In the position not shown, rotated a further 15°, i.e., the 60° position, a single access area 11 is again formed, which has an opening angle of 60°. In this 60° position, the door leaf 3, which in view a), i.e., the desired access position, was located directly in front of the access area 11 of the access opening 7, is now located directly after the access area 11 of the access opening 7. For the subsequent positions according to the following 59°, i.e., the 61° position up to the 119° position, the access area 11 remains fully open. In the position rotated a further 60°, i.e.,From view b) a position rotated by 75° further, the fictitious 120° position exists, which is again a new 0° position in which the access area 11 is again maximally open and which position can again be considered the desired access position for this lower access opening 7.

[0068] Fig. 4 Figure 1 shows a schematic top view of a double-leaf revolving door 1, specifically in view a) in a first position with persons P1, P2, P3, and P4 in the vicinity of the revolving door, and in view b) in a second position of the revolving door rotated 90° further compared to the position in view a). View a) shows the 0° position of the double-leaf revolving door 1. From this position to the position shown in view b), the door leaves 3 have been rotated 90° further. View b) shows the 90° position, where, due to the wide outer edge 12, there is no free access area 11, but rather it is completely blocked.

[0069] In the case of the double-leaf revolving door 1 according to Fig. 4 With two door leaves 3, the two door leaves run in a line, forming an angle of 180° between them. The access opening 7 is again configured to provide a maximum opening angle (access opening angle α 1) of 60°, which can also be maintained over a longer rotation range. View a) shows the 0° position of the double-leaf revolving door 1. From this position to the position shown in view b), the door leaves 3 have been rotated a further 90°. View b) therefore shows the 90° position, and due to the wide outer edge 12, there is no free access area 11, but rather it is completely blocked.

[0070] The desired access position of the double-leaf revolving door 1 according to Fig. 3 This is not shown, but exists in a position rotated only 45° further from view a), i.e., the 45° position of the double-leaf revolving door 1, when the two outer edges 12 are each positioned with their foremost area, viewed in the direction of rotation v, directly in front of the access area 11 of the entrance opening 7. Here, the maximum opening angle of 60° (walk-through opening angle α 1 ) is provided, and a person can also enter the passage area 7a as far as possible, up to the next door leaf 3 in the direction of rotation.

[0071] According to further embodiments, the desired access position can also be preset differently for all illustrated and described revolving doors 1. In particular, the example of the double-leaf revolving door 1 makes it clear that setting the 0° position as the desired access position can also be preferable, since this ensures the maximum opening width of 60° (walk-through opening angle α 1) and simultaneously provides a certain free depth of the passage area 7a, so that persons entering have space in the direction of rotation v to enter the interior, but at the same time the maximum opening width of 60° (walk-through opening angle α 1) is guaranteed for a further period of time, namely for a further rotation of another 45°, in order to allow subsequent persons to also enter the same passage area 7a.

[0072] It may therefore be particularly advantageous if the desired access position or the predetermined opening angle α 1 is variable relative to the presumed arrival time of person P1 or P2, and in particular depends on the recorded sensor data, such as the number of people detected.

[0073] Preferably, the door leaves 3 can be rotated such that the desired entry position is set at the anticipated arrival time of the person, or of the first person among several people. Preferably, the desired entry position can be adjusted depending on the number of people registered with an entry request. In particular, it is preferred that, for a double-leaf revolving door 1, the 0° position is set as the desired entry position for groups of up to two (alternatively up to three, alternatively up to four, alternatively up to five) people with an entry request, while for groups of more than two (alternatively more than three, alternatively more than four, alternatively more than five) people with an entry request, the 45° position is set as the desired entry position.

[0074] In principle, it can be provided that the estimated time of arrival for groups of several people wishing to enter is determined by the person whose arrival is most likely to be at carousel door 1, based on the recorded speed and direction of approach.

[0075] Regarding the specific situation of entry or passage by persons, such as persons P1, P2, P3 and P4 in views a) of the Fig. 2 , 3 and 4 , an approach side 13 and an exit side 14 of the revolving door 1 can always be defined. From the approach side 13, in the cases of the Fig. 2 bis 4 Persons P1, P2, P3 and P4 can approach the revolving door 1 from the outer side of the building 6 in order to get to the other side, i.e. the inner side of the building 5 and thus the exit side 14, through the revolving door 1.

[0076] Specifically, the movements of people can be detected by sensor D5 in the detection area E5 marked by the dashed line, and by sensor D6 in the detection area E6 on the approach side. Therefore, in the cases shown, the movement of person P4 cannot yet be detected. The movements of people P1, P2, and P3 can be detected and analyzed. The respective arrow indicates a vector representing the speed and direction of approach of each person P1, P2, or P3. Based on the sensor data, it can be concluded that person P3 is moving away from revolving door 1 and therefore likely does not intend to enter. Only people P1 and P2 are moving towards revolving door 1, and thus an intention to enter can be assumed.

[0077] Furthermore, it can be determined that person P1 will probably reach carousel door 1 first, because firstly, they are located closer to the (lower) access opening 7 and secondly, they are moving faster (represented by the larger vector arrow).

[0078] To illustrate the advantages of the proposed procedure, one can refer to the Fig. 2 bis 4 , as well as simultaneously on the Fig. 5 Reference will be made to this.

[0079] Fig. 5 Figure 1 shows a flowchart of a proposed procedure for operating a fully automatic revolving door 1. The procedure comprises the following steps: After the revolving door 1 is initially provided with at least two door leaves 3 in step S100, as already described above, by... Fig. 1 and 2The illustrated example of a four-leaf revolving door 1 with four door leaves 3, and of a three-leaf revolving door 1 with three door leaves 3 (see. Fig. 3 ) and in the case of a double-leaf revolving door 1 with two door leaves 3, as well as a drive 8 and at least one sensor D5 or D6 for detecting person movements, wherein the drive 8 of the revolving door 1 can rotate the at least two door leaves 3 within a passage area 7a of the revolving door 1, the aforementioned detection of person movements takes place in step S200. For this purpose, the at least one sensor D5 or D6 detects the person movements in its respective detection area E5 or E6, specifically the speed and direction of approach of at least one person P1 or P2 approaching from the approach side 13 of the revolving door 1. Subsequently, in step S300, a presumed arrival time of person P1 or P2 at the revolving door 1 is calculated based on the detected speed and direction of approach. Specifically, the estimated arrival times can be calculated for both persons P1 and P2.However, it is also possible to first deduce which person is expected at the door first, in this case person P1, and only calculate their estimated arrival time. In any case, the control of the revolving door 1 should regularly be directed, in cases where it depends on the estimated arrival time, towards the estimated arrival time of the first arriving person P1. In addition to the speed and direction of approach, the position of the detected person P1 or P2 is naturally also included in the two aforementioned calculation methods. The Motion-IQ technology of the present applicant can be used, or reference can also be made to the applicant's disclosure EP4095341A1. Using a corresponding technology, with which the detection area E6 or E5 in front of the revolving door 1 is monitored via the sensor D6 or D5, the area in front of the door is observed, and the direction and speed of movement of person P1 or P2 are used to calculate the expected arrival time.P2 calculates the arrival time or, more generally, a desired passage time. Similarly, this technology can also be used to calculate or estimate a departure time, whereby assumptions can be made about how long a person P1 or P2 typically needs to pass through the revolving door 1, an assumption which can also be dependent on the person's speed. In step S400, the at least two door leaves 3 are then accelerated by the drive 8 such that an access area 11 of an entry opening 7 of the revolving door 1 has a predetermined passage opening angle α 1 at the presumed arrival time of person P1, P2.

[0080] The predetermined pedestrian opening angle α1 can, for example, correspond to the maximum possible opening angle due to structural constraints. Accordingly, the predetermined pedestrian opening angle α1 can, for example, be the maximum possible opening angle for a double-leaf revolving door 1 (see figure). Fig. 4 , there in particular view a)) preferably be 60°. In the case of a three-leaf revolving door 1 (see Fig. 3 , there in particular view a)), the preferred access opening angle α 1 can therefore also be 60°. In the case of a four-leaf revolving door 1 (see Fig. 2 , in particular view a)), the preferred opening angle α 1 can be 90°. These angles ensure that the access area 11 of the access opening 7 of the respective revolving door 1 is optimally open, i.e., at its maximum width, at the expected arrival time of person P1 or P2, in order to allow seamless passage.

[0081] Alternatively, angle ranges can be preferred that are possible at a presumed arrival time, so that the maximum possible opening width does not necessarily have to be available. Accordingly, the predetermined pedestrian opening angle α 1 can, for example, be set for a double-leaf revolving door 1 (see figure). Fig. 4 ) of 45° to 60°, more preferably between 50° and 60°, more preferably between 55° and 60° (either in front of or behind the door leaf 3, but preferably in front of the door leaf 3). In the case of a three-leaf revolving door 1 (see Fig. 3 The predetermined opening angle α1 can therefore be between 30° and 60°, particularly preferably between 45° and 60°, and more preferably between 55° and 60° (either in front of or behind the door leaf 3, but preferably in front of the door leaf 3). In the case of a four-leaf revolving door 1 (see... Fig. 2 The predetermined opening angle α1 for passage can be between 55° and 90°, particularly preferably between 75° and 90°, and more preferably between 80° and 90° (either in front of or behind the door leaf 3, but preferably in front of the door leaf 3). These angle ranges ensure that the access area 11 of the access opening 7 of the revolving door 1 is sufficiently open at the expected arrival time of person P1 or P2 to allow seamless passage.

[0082] To achieve the predetermined opening angle α 1 at the expected arrival time, acceleration and / or deceleration processes can be carried out.

[0083] In principle, it is conceivable to adjust the passage rotation speed provided by the drive 8, and specifically to the speed of the person P1 or P2 passing through. For this purpose, when dealing with a group of people or several people P1, P2, the speed of the slower person P2 should be used as the basis for adjusting the passage rotation speed. If this requires accelerating the door leaves 3 to a higher rotation speed than previously present, it may be preferable to subsequently decelerate the door leaves 3 back to the lower base rotation speed.

[0084] For this purpose, or more generally, it can be useful to detect when a person leaves the area of ​​the revolving door 1 after passing through it. It is therefore conceivable that, following the motorized assistance of the rotational movement of the at least two door leaves 3 by the drive 8 according to the rotational speed of the person passing through, this assistance or level could be automatically readjusted. This could, for example, occur at a specific time chosen based on a calculated, presumed exit time, such that the assistance of the rotational movement ends when person P1 or P2 is about to leave the passage area 7a of the revolving door 1.

[0085] However, it is also conceivable that the drive 8 stops supporting the rotational movement of the at least two door leaves 3 when person P1 or P2 has actually passed through the passage area 7a of the revolving door 1, for example, completely. Additional auxiliary sensors can be used for this purpose, such as the auxiliary sensor D5b (see...). Fig. 2 bis Fig. 4 ), which auxiliary sensors monitor the exit side 14 of the revolving door 1. Advantageously, this can be a very simple auxiliary sensor D5b, which only detects the presence of person P1 or P2 passing through the passage area 7a of the revolving door 1 and exiting accordingly at the exit side 14.

[0086] As part of step S100, or generally following a person P1 or P2 passing through the revolving door 1 and, if necessary, before any motor assistance for the rotation of the revolving door 1 stops, a desired access position of the revolving door 1 can also be set. The desired access position is preferably preset such that the outer edges 12 of the at least two door leaves 3 are not in the access area 11 of the access opening 7 of the revolving door 1. In this way, the next time a person passes through, a particularly smooth, seamless passage through the passage area 7a of the revolving door 1 is possible, without the risk of collision with the outer edge 12 or the need for unnecessary waiting in front of the revolving door 1. It is further preferred that an outer edge 12 of one of the at least two door leaves 3 in the desired access position is just in front of, or...furthermore, preferably located directly in front of the access area 11 of the access opening 7. This allows for the most extensive possible walking area directly into the passage area 7a and minimizes the time required for the passage of person P1 or P2.

[0087] At the in Fig. 5 the procedures shown and described above, or in the case of the corresponding revolving doors 1 according to Fig. 1 bis Fig. 4 It is possible to preset the stopping of the motorized assistance for the rotation of the door leaves 3. Specifically, the stopping of the motorized rotation of the at least two door leaves 3 by the drive 8 can be implemented, for example, in such a way that the stopping occurs with a time delay, so that even if person P1 or P2 has passed through the revolving door area, the at least two door leaves 3 are automatically rotated by the drive 8 into a desired, further rotated stopping position. This stopping position can be defined such that, in the desired, further rotated stopping position, no outer edge 12 of the at least two door leaves 3 is located in the access area 11 of the access opening 7. It can be specifically stipulated that the desired, further rotated stopping position is the previously described desired access position.

[0088] The proposed revolving doors 1, as depicted and described, can be operated in different modes. The revolving door 1 can be configured for a first automatic operating mode in which the at least two door leaves 3 are stationary in a basic state. This means that the door leaves 3 do not rotate continuously or automatically, but are in a resting position. Furthermore, the revolving door 1 can be configured for a second automatic operating mode in which the at least two door leaves 3 are continuously rotated at a low speed by the drive 8. A low rotational speed in this context means that it is lower than the rotational speed produced by the drive 8 in an actual passage situation, when a person wants to pass through the revolving door 1.Accordingly, the torque provided by the drive 8 in the second automatic operating mode at low rotational speed is less than the torque provided by the drive 8 when a person passes through the revolving door 1.
