Description
TECHNICAL FIELD
[0001] The present disclosure relates to a high-speed door. TECHNICAL BACKGROUND
[0002] Lift gates have been used for some time, for example, in factories or warehouses as passageways or driveways between separate areas. Such lift gates are equipped with a vertically movable gate leaf, which is guided in two lateral gate frames. The gate leaf is pulled upwards by a drive mechanism when the gate is opened and lowered downwards when the gate is closed. State-of-the-art gates include gates with a flexible, film-like gate leaf and gates with segmented gate leaves, each with individual, fixed segments pivoting to one another.
[0003] DE 10 2021 122 013 B4 describes a drive device for a lifting gate, a lifting gate with such a drive device, and a method for operating such a lifting gate. The drive device has an inner shaft and an outer hollow shaft, wherein the outer hollow shaft is arranged concentrically to the inner shaft and surrounds it. The inner shaft is designed to be mounted on a lifting gate in a installed state of the drive device in a rotationally fixed manner. When the drive device is started up in the installed state, the outer hollow shaft rotates around the inner shaft. The described lifting gate comprises such a drive device, two door frames, a door lintel, and a control panel. The drive device is mounted in a rotationally fixed manner in the door lintel. A door leaf is guided in the door frame and can be opened or closed by the drive device.
[0004] In conventional lifting gates, the drive device, which serves to open and close the lifting gate, is operated by an external energy source that is not part of the lifting gate itself. In order to supply the drive device with electrical energy, the lifting gate is usually connected to the power grid of a building into which the gate is integrated. It is therefore necessary that the appropriate electrical cables and connections are available at the appropriate installation location. The lifting gate is usually included in the planning phase of the construction or renovation of the respective building so that the appropriate electrical cables and connections can be planned and are available in the necessary positions when the lifting gate is installed. Conventional lifting gates are usually controlled by control panels attached locally to the gate or by motion detectors attached to the gate. DESCRIPTION
[0005] Accordingly, the object of the invention is to provide a lifting gate which can be subsequently installed in a location and does not require a connection to an external power supply.
[0006] This object is achieved by the subject matter of the independent claims. Further embodiments emerge from the dependent claims and the following description.
[0007] According to a first aspect, a self-contained smart high-speed door is provided. The smart high-speed door comprises a first door frame and a second door frame, a door leaf guided between the first door frame and the second door frame, a drive device with at least one DC motor, a DC energy source that supplies the drive device with energy, and a controller configured to control the operation of the drive device. The drive device is configured to raise and lower the door leaf to selectively open or close a passage defined by the first door frame and the second door frame. The DC energy source is configured to supply the drive device with energy independently of an external energy network. The DC energy source is connected to the drive device.
[0008] The first door frame and the second door frame run vertically along the sides of the opening area of the lifting door and can be connected to a door head. The door frames contain suitable means for holding the door leaf in a plane of the opening area of the door and for guiding it vertically, so that the door leaf can slide up and down vertically along the door frames. For example, the door frames can contain rails designed to accommodate correspondingly designed guide rollers attached to the door leaf.
[0009] The door leaf can be a film-like door leaf or a solid door leaf consisting of several interconnected individual segments that form a flat door leaf when the lift door is closed and seal off the opening area of the lift door. Such a segmented door leaf can, for example, be the door leaf of a standard sectional door or a spiral high-speed door.
[0010] The drive device can, for example, be located in the door lintel. Such a lintel forms a space for accommodating the drive device and runs horizontally between the two door frames above the door's opening area.
[0011] The drive device can be any suitable drive device. For example, the drive device can comprise an external rotor motor or an internal rotor motor. The corresponding motor can, for example, be mounted on the side of the door head and configured to raise or lower the door leaf through its rotation. The motor can, for example, be connected to the door leaf by means of chains, belts, or other transmission devices to raise and lower the door leaf.
[0012] The drive device preferably has an inner shaft with an inner shaft length and an outer hollow shaft with a hollow shaft length. The outer hollow shaft is concentrically aligned with the inner shaft. The inner shaft is mounted on the lifting gate (or laterally on its lintel) in a rotationally fixed manner. The outer hollow shaft rotates around the inner shaft when the drive device is operated in the installed state.
[0013] Such a drive device is thus integrated into the lintel of the lifting gate. In the following, such a drive device is referred to as a "tubular motor." The inner shaft can be a standard shaft with suspension or bearing points at its ends.
[0014] In the prior art, such a shaft is usually driven directly by a motor, whereby the drive force can be transmitted via the shaft to various transmission means such as belts or toothed pulleys in order to open and close the gate. In the tubular motor, however, the inner shaft is designed so that its ends are mounted in a door lintel for non-rotation purposes when the drive device is installed in the lifting gate. The inner shaft therefore does not rotate when the drive device is in operation, but is stationary relative to the lifting gate. For this purpose, the inner shaft can be fastened in a rotationally fixed manner, for example, in corresponding recesses in the sides of a door lintel. For this purpose, the inner shaft can be screwed, riveted or connected to the door lintel at its ends in a rotationally fixed manner in some other suitable way.
[0015] The outer hollow shaft, on the other hand, is a type of tube that is arranged concentrically, i.e., with the same center point, around the inner shaft. The outer hollow shaft is rotatable relative to the inner shaft. For example, the outer hollow shaft can be driven or rotated relative to the inner shaft by one or more motors.
[0016] For this purpose, the outer hollow shaft can, for example, be rotatably mounted at its ends in the lintel of the lifting gate, so that the hollow shaft can be rotated about its central axis without changing its position relative to the lintel in the horizontal or vertical direction.
[0017] In a lifting door with a foil-like door leaf or curtain, the outer hollow shaft can also be used to directly pick up or wind up the door leaf when the door is opened. However, in a door with a fixed or segmented door leaf, the torque of the drive mechanism can also be transmitted through the outer hollow shaft to other movement and transmission elements, thus raising or lowering the door leaf.
[0018] In versions with a tubular motor, the outer hollow shaft preferably has an outer diameter of approximately 180 mm. However, other diameters are also conceivable depending on the available installation space and requirements.
[0019] The inner shaft and outer hollow shaft of a tubular motor can, for example, be made of a metallic material such as steel or aluminum. However, it is also conceivable for the inner shaft and outer hollow shaft to be made of other suitable materials, such as high-strength plastic or any other suitable material. This list is merely exemplary, however, and other materials are also conceivable.
[0020] In a drive device designed as a tubular motor, the at least one DC motor is a DC motor with an outer motor element and an inner motor element. The inner motor element is mounted on the inner shaft for rotation therewith. The outer motor element surrounds the inner motor element and is connected to the inner motor element via a rotatable connection. The outer hollow shaft surrounds the outer motor element and is connected to the outer motor element via a rotation therewith. Such a motor can be an external rotor motor, with the stator arranged inside and surrounded by the rotor. The inner motor element therefore corresponds to the stator of the DC motor. The outer motor element corresponds to the rotor of the DC motor.
[0021] Since the inner shaft of such a tubular motor is rotationally fixed relative to the lifting gate or the lintel of the lifting gate, and the inner motor element is rotationally fixed on the inner shaft, the inner motor element cannot rotate or move relative to the lintel of the lifting gate. The fact that the inner motor element is rotationally fixed on the inner shaft means, in particular, that the inner shaft extends centrally through the inner motor element and is rotationally fixed to it. The inner shaft thus functions as the output shaft of a standard electric motor, but this drive shaft is prevented from rotating by the rotationally fixed connection to the lintel.
[0022] The outer motor element of such a tubular motor surrounds the inner motor element so that the latter is also arranged concentrically to the inner shaft. In other words, the inner shaft, the inner motor element, and the outer motor element are arranged concentrically with respect to a common axis of symmetry that runs along the longitudinal direction of the inner shaft. The outer motor element is rotatably mounted relative to the inner motor element about this common axis of symmetry. The inner motor element therefore surrounds the inner shaft and is firmly connected to it. The outer motor element, in turn, surrounds the inner motor element and is rotatable relative to it. The inner motor element can contain permanent magnets or one or more electromagnets formed with corresponding coils. The outer motor element can also contain one or more electromagnets with magnetic coils or permanent magnets.However, at least one of the inner motor element and the outer motor element includes at least one electromagnet.
[0023] Since the outer hollow shaft is non-rotatably connected to the outer motor element (rotor), the inner shaft is non-rotatably connected to the lifting gate and to the first motor element (stator), and the outer motor element is rotatable relative to the inner motor element, activation of the DC motor causes the outer motor element, and thus the hollow shaft connected to the outer motor element, to rotate.
[0024] In other words, in this arrangement, the output shaft of a standard electric motor is held in place, causing the outer casing of the motor (and thus the connected outer hollow shaft) to rotate. In a tubular motor, the outer hollow shaft may be an integral part of the outer motor element, or a separate component connected to the outer motor element by any suitable means, such as gluing, welding, riveting, or similar. However, the outer motor element may also be press-fitted into the outer hollow shaft to create a frictional connection.
[0025] Optionally, in a tubular motor, a cooling device, such as a fan or any other suitable cooling device, can also be arranged on one or both sides of the outer hollow shaft. Such a cooling device can be designed to create an air flow from the outside into the hollow shaft and thereby cool the first motor. For this purpose, cooling openings can also be arranged in the outer hollow shaft, for example, which serve as exhaust openings for the air introduced by the cooling device. As an alternative to such air cooling, a liquid cooling system can also be installed around the first motor.
[0026] It should be noted that although the drive device is described in detail above with a tubular motor, any other suitable drive device can also be used. A drive device with a tubular motor as described above can, however, be used for a wide variety of lifting doors without major modifications. Such a drive device can, for example, be used for lifting doors with flexible / film-like door leaves, for lifting doors with fixed door leaf segments such as spiral doors, or for standard sectional doors. Only minor modifications are necessary. The use of a static central inner shaft and an outer hollow shaft with motors arranged in between also creates a space-saving drive device, as the motors do not have to be housed laterally in the door headroom, but are located within a tube that also serves to hold the door leaf.
[0027] In general, the drive device, or rather the DC motor of the drive device, can provide a power of approximately 1 kW and a force of approximately 1.2 kN. However, other technical specifications are also possible, depending on the specific application. In particular, the motor power must be large enough to lift the respective door leaf of the self-contained smart high-speed door. A total motor power of up to 3 kW is particularly preferred. This power can be provided by at least one DC motor alone or, as described below, by multiple motors.
[0028] The technical characteristics of the DC motor can be designed in particular so that the self-contained smart high-speed door can be operated at an opening speed of up to approximately 4 m / s. Conventional industrial lifting gates are typically operated at opening speeds of 0.2 m / s to 0.3 m / s. The DC motor can, for example, be designed as a DC motor with a commutator (commutator motor). However, other suitable DC motors known to those skilled in the art can also be used.
[0029] The controller is configured to control the operation of the self-contained smart high-speed door and can be any suitable control component, such as a general-purpose computer, an ASIC circuit, an FPGA, or any other circuit component that enables the drive device to be controlled and thus to open and close the self-contained smart high-speed door. The controller also includes corresponding non-volatile and volatile memory components, such as random access memory (RAM) and persistent memory, which contains the programming of the controller. The controller can receive automatic inputs (e.g., from sensors and other systems connected to it) and / or manual inputs (e.g., from a user, either directly or via other devices connected to the controller).The control system can receive commands regarding the opening, closing and stopping of the door, for example, via a control panel / user interface attached to the self-contained smart high-speed door, via an external user interface (described below), via proximity sensors or other sensors, etc.
[0030] The DC power source provides the power for the drive unit (and also for the control system). It is directly connected to the drive unit and, upon request from the control system, supplies it with a DC voltage, which is used to raise or lower the door leaf as required. Furthermore, the DC power source can also supply the drive unit with power to hold the door leaf in a current position. For this purpose, the DC motor of the drive unit can be driven in the opening direction with a power sufficient to overcome the force of gravity, but not enough to lift the door leaf.Although the DC power source is directly connected to the drive device, it may itself include an electrical buffer storage device, such as a battery or a capacitor, to enable operation of the drive device even when the DC power source is not producing any electrical current.
[0031] The DC power source is part of the lifting gate itself and can be any suitable power source that delivers a DC voltage and is capable of driving the drive mechanism. However, the DC power source being part of the lifting gate itself does not necessarily mean that the DC power source is directly attached to the lifting gate. For example, the DC power source can also be retrofitted on a building roof and connected to the drive mechanism or an energy buffer, as described below.
[0032] The direct current energy source can be connected to the drive device via an energy buffer, such as a battery or other suitable energy storage device. The energy buffer then serves to supply the drive device with electrical energy even when the direct current energy source is not currently supplying any electrical energy. This can be the case, for example, if the direct current energy source (as described below) is a solar cell module. It is also conceivable for the energy buffer to be connected in parallel between the direct current energy source and the drive device, so that the direct current energy source supplies the drive device directly with energy when the direct current energy source is supplying sufficient energy, but the energy buffer supplies energy when the direct current energy source is not currently providing sufficient energy.The energy output of the energy buffer to the drive device can also be controlled with the controller.
[0033] The direct current energy source operates independently of an external power grid. An external power grid is defined as an energy grid that is not part of the self-contained smart high-speed door itself. In particular, an external power grid also includes a building's electrical grid. The disclosed self-contained smart high-speed door can thus operate independently of the building's electrical grid and thus "self-sufficiently," as it does not rely on an external energy source. This allows the self-contained smart high-speed door to be retrofitted into buildings, for example, in warehouses or production halls, without the need for corresponding power lines / power lines at the respective installation location. High-speed doors (or doors in general) are typically planned during the construction phase, which is why the corresponding power connections are usually present in the required positions.However, since the self-contained smart high-speed door does not require such connections, it can be retrofitted cost-effectively into an existing building infrastructure in which no door was previously planned.
[0034] No current conversion whatsoever between direct current and alternating current takes place between the direct current energy source and the drive device (i.e. between the direct current energy source and the energy buffer and between the energy buffer and the drive device), in particular no DC-AC conversion and / or AC-DC conversion. For state-of-the-art gates operated with a DC motor, however, at least AC-DC conversion is always required, as these are connected to building power networks that operate with alternating current in order to minimize line losses. By omitting such current conversion, conversion losses are avoided. However, DC-DC current conversion can take place between the energy buffer and the drive device in order to enable, for example, speed ramps and different opening and closing speeds.Such a DC-DC power conversion can also be controlled via the controller.
[0035] According to one embodiment, the direct current energy source comprises a renewable energy source integrated into the smart high-speed door.
[0036] The direct current energy source can be any suitable renewable energy source, such as a solar cell or a wind turbine.
[0037] For example, if the self-contained smart high-speed door is used as a gate between the interior of a hall and an outdoor area, a wind turbine can be installed relatively easily outside the building and connected to the drive device.
[0038] According to a further embodiment, the renewable energy source is a solar cell module.
[0039] A solar cell module can be arranged on the high-speed door (for example on the outside of the high-speed door), particularly when the self-sufficient smart high-speed door is used as a passage between the interior of a building and an exterior of the building, in such a way that the solar cell module is irradiated with solar radiation and thus produces electrical energy to operate the self-sufficient smart high-speed door.
[0040] According to a further embodiment, the smart high-speed door further comprises an embedded subscriber identification module (eSIM), which connects the controller to a cellular network, and / or a wireless network module (WLAN module), which connects the controller to a wireless network (WLAN). The self-contained smart high-speed door can be controlled via an external user interface connected to the cellular network or WLAN.
[0041] An eSIM is an embedded SIM card and serves like a replaceable physical card for user identification in a mobile network. Subscriber information is securely embedded in a soldered module and can be modified via software. This module is either a small physical integrated circuit (eSIM) or a software enclave (iSIM) of a system-on-a-chip. The eSIM can replace the traditional SIM card.
[0042] However, a physical SIM card can also be used instead of or in addition to an eSIM. For this purpose, the control unit can include a corresponding interface or socket into which a SIM card can be inserted to connect the high-speed door to a mobile network.
[0043] In addition to or as an alternative to an eSIM / SIM, the control unit can also be connected to a WLAN via an integrated WLAN module. It is also conceivable for the control unit to have a LAN interface for a wired connection to a local network. Furthermore, the control unit can also include a transponder or a transponder reader, so that the self-contained smart high-speed door opens automatically, for example, when a user with a corresponding transponder approaches the self-contained smart high-speed door and closes again when the user with the transponder moves away from the self-contained smart high-speed door.
[0044] The control system can be connected to a corresponding server, for example, via the cellular network and / or WLAN / LAN via a wide area network (WAN), such as the Internet. The local network can provide appropriate routing services for this purpose. However, the corresponding server can also be directly connected to the local network (especially if WLAN / LAN is used), allowing the external user interface to connect to the high-speed door directly via the local network and without access to a WAN.
[0045] However, the controller itself can also function as a server, which can be accessed via the mobile network or the WAN / LAN (for example via a corresponding IP address).
[0046] The external user interface, in turn, is an interface or device that is not part of the self-contained smart high-speed door itself. The external user interface can, for example, contain appropriate software to control the functions of the self-contained smart high-speed door and receive messages from the self-contained smart high-speed door's control system. Control can be performed by the user via appropriate user inputs or automatically via the external user interface.
[0047] According to another embodiment, the external user interface is a user's mobile device.
[0048] Such a mobile device could be, for example, a smartphone carried by a user or another network-capable device. The software for controlling the self-contained smart high-speed door could then be, for example, a corresponding app on the smartphone configured to receive operating inputs from a user. Such operating inputs could include, for example, inputs to open the door, close the door, or stop the door in an emergency.
[0049] However, the software can also be configured to execute control functions of the self-contained smart high-speed door itself when defined conditions are met, i.e., to independently send corresponding command signals to the control system of the self-contained smart high-speed door via the mobile network or WLAN / LAN. For example, the software of the mobile device can continuously monitor the position of the mobile device and automatically open the self-contained smart high-speed door when the mobile device approaches the high-speed door, i.e., when it comes within a threshold distance of the door. Conversely, the mobile device can also automatically close the self-contained smart high-speed door when the mobile device moves away from the self-contained smart high-speed door.
[0050] Such functions can be controlled, for example, using a geofence defined by the autonomous smart high-speed door. For example, a delivery driver driving into a warehouse could carry a mobile device such as a smartphone that continuously monitors their position and compares it with a geofence defined by the autonomous smart high-speed door. As soon as the driver or vehicle enters the geofence, the mobile device can send a command to open the autonomous smart high-speed door. Conversely, the mobile device can send a command to close the autonomous smart high-speed door when the driver exits the geofence.In particular, the use of a geofence avoids repeated and unnecessary opening and closing operations, which would occur, for example, if the mobile device were to send corresponding commands when the mobile device approaches or moves away from the gate in close proximity (which could be detected, for example, by a Bluetooth connection between the mobile device and the control system or by means of a transponder signal or similar).
[0051] It is also conceivable for the mobile device to communicate with the control system via other communication connections (e.g., via short-range communication such as Bluetooth connections), allowing the door to be stopped, for example, when a user with the mobile device is in the door opening. Such safety functions can be implemented redundantly to other safety functions, such as light barriers.
[0052] The control processes by the mobile device described above are merely exemplary in nature and other suitable control processes and / or inputs are also conceivable.
[0053] According to a further embodiment, the communication of the external user interface with the controller takes place via an encrypted communication protocol.
[0054] Encrypting communication prevents or at least hampers misuse by unauthorized persons. For example, an unauthorized person could attempt to open the self-contained smart high-speed door using appropriate commands and thus break into the building. End-to-end encryption of communication makes such attempts more difficult.
[0055] Encryption can be implemented using any suitable protocol. For example, the connection between the external user interface and the controller (e.g., directly or via a corresponding server, as described above) can be implemented via an encrypted virtual private network (VPN).
[0056] According to a further embodiment, the controller is configured to send a warning signal to the external user interface when an undesirable event occurs.
[0057] An undesirable event is, for example, an event that was neither requested by a user nor appears to be appropriate with regard to automated control operations. The control system can, for example, monitor the operating status of the autonomous smart high-speed door and detect when such an undesirable event occurs. For this purpose, the control system can, for example, include a lookup table with unusual or abnormal operating states. The operating states can include, for example, the position of the door leaf, movement data of the door leaf (such as its speed and acceleration), externally acting forces, and the like. For this purpose, the autonomous smart high-speed door can include corresponding sensors that communicate with the control system.In certain versions, the control system can also detect undesirable events using artificial intelligence, for example through various machine learning algorithms.
[0058] As soon as an undesirable event occurs, the control system can send a corresponding warning message to external user interfaces that communicate with it, as described above. The control system can also encompass different classes of user interfaces. For example, it is conceivable that a warning message is sent to an owner, proprietor, or operator of the self-contained smart high-speed door, but not to delivery personnel / drivers or other persons who can control the self-contained smart high-speed door but lack any additional authorizations.
[0059] According to a further embodiment, the undesirable event comprises at least one of the following: a break-in or a break-in attempt through the smart high-speed door, an emergency at the smart high-speed door, or a lack of energy supply to the drive device.
[0060] For example, if the door leaf is moved / opened without being triggered by the control system, this can be detected as a break-in attempt. An emergency on the self-contained smart high-speed door could be a trapped person or object, which can be detected, for example, by an overload of the drive device. A power outage can be detected, for example, by monitoring the voltage or current of the DC power source. If the voltage drops below a threshold, this is an indication of a power outage, for example, if a solar cell is not receiving any or insufficient irradiation.
[0061] Furthermore, it's conceivable to automatically inform other entities in certain situations. For example, the self-contained smart high-speed door could automatically report a break-in attempt to the police. In the event of a trapped person, it's also conceivable to send a report to an ambulance. In the event of a power outage, it's conceivable to notify a service technician, etc.
[0062] According to a further embodiment, the drive device comprises at least two modular DC motors, so that a required power of the drive device can be adjusted as needed.
[0063] For example, a door with a fixed door leaf requires more power than one with a film curtain due to the heavier weight of the door leaf. The height of the self-contained smart high-speed door also affects the required power due to the weight of the door leaf being moved. A taller door, for example, requires more power from the drive unit.
[0064] The DC motors can be modular motors, which can have the same or different performance characteristics. The second modular DC motor can be constructed the same as the first DC motor or differently from the first.
[0065] In a design with a tubular motor, for example, standardized modular DC motors or motor units can be inserted into the outer hollow shaft to achieve the intended / required power. For example, as described above, modular DC motors can be pressed into the outer hollow shaft in the required number to increase the power of the drive device accordingly. Each of the DC motors can be designed according to the DC motor described above.
[0066] Instead of using a second DC motor, the length / extension of the first DC motor can also be varied in a tubular motor to adapt to the required power. Maximum power is available when the first DC motor occupies the entire length of the outer hollow shaft. Using two or more DC motors allows for an increase in total power and total torque, as does using a DC motor extending over the entire length of the hollow shaft, since all DC motors transmit their torque along the same axis of rotation and the torques of several DC motors are therefore added together. Of course, in a design with more than one DC motor, the first motor cannot occupy the entire length of the outer hollow shaft.
[0067] According to another embodiment, the self-contained smart high-speed door further comprises at least one sensor for monitoring environmental conditions. The controller is configured to detect occurring service requirement events and send them, along with the sensor data prevailing at the time of the service requirement event, to a higher-level entity for statistical big data analysis in order to predict future service requirement events based on the statistical big data analysis.
[0068] For example, different wear parts of the self-contained smart high-speed door may wear at different rates under different environmental conditions such as temperature, humidity, air pollution, and the like. The control system can therefore continuously monitor such environmental conditions. In addition, environmental conditions such as noise or changes in resistance in springs, which indicate wear or defects in the lifting door, can also be monitored using appropriate sensors. When a service requirement event occurs, such as the need for a replacement part due to a defect or wear, the control system sends this service requirement along with the corresponding sensor data about the environmental conditions to a higher-level entity, such as a cloud server.The cloud server can then statistically correlate the occurrence of the corresponding service demand events with the corresponding environmental conditions prevailing at the time of occurrence, for example using artificial intelligence, as part of a big data analysis.
[0069] Emergency stops, for example, can also influence the service life of individual components, so that such data can also be included in the big data analysis.
[0070] Based on this big data analysis, future service requirement events or failure / service probabilities can then be predicted. For example, the self-contained smart high-speed door can continuously monitor the environmental conditions and send them to the higher-level entity. The higher-level entity can then predict in advance when a service requirement event will occur in the future based on the environmental conditions and, for example, the duration of these conditions. For example, a "mean time for failure" of individual components can be determined.
[0071] For example, several autonomous smart high-speed doors can be connected to the parent entity, and each of these autonomous smart high-speed doors can send the data described above to the parent entity, allowing this data to be incorporated into the big data analysis. Thanks to this "swarm intelligence" implemented in this way, the future service requirements for each of the autonomous smart high-speed doors can be identified and, for example, communicated to a user at an early stage. For different autonomous smart high-speed doors, the corresponding type data can also be taken into account.
[0072] According to a further embodiment, the at least one sensor for monitoring environmental conditions is selected from the group comprising: an ambient temperature sensor, a humidity sensor, a particle sensor, a noise sensor and a resistance sensor.
[0073] According to a second aspect, a smart high-speed door kit is provided. The smart high-speed door comprises a smart high-speed door and a self-sufficient DC power source. The smart high-speed door and the self-sufficient DC power source are configured such that the smart high-speed door is supplied with power from the DC power source in such a way that the smart high-speed door can be operated independently of an external power grid.
[0074] In summary, the invention provides a self-contained smart high-speed door suitable for easy retrofitting in a building. In particular, no connection to an external power grid, such as a building's power grid, is required, thus avoiding the need for subsequent installation of corresponding power connections. The disclosed self-contained smart high-speed door can also enable "smart" control functions, such as manual and / or automatic control via a user's smartphone, thereby increasing operating convenience and avoiding unnecessary opening and closing operations. Furthermore, the future service requirements of the self-contained smart high-speed door can be identified early on using a big data analysis. The performance of the drive device can be easily adjusted as needed using modular motor units.In conjunction with an external user interface, it also provides the ability to send warning messages to a user in the event of unwanted events. BRIEF DESCRIPTION OF THE CHARACTERS

Fig. 3 A schematic side view of the drive device from Fig. 2 . DETAILED DESCRIPTION OF EMBODIMENTS
[0076] Fig. 1 shows a schematic representation of a self-contained smart high-speed door 10 according to an exemplary embodiment of the present disclosure. The left side of the Fig. 1 shows the self-contained Smart High-Speed Door 10 in a schematic side view. The right side of the Fig. 1 shows the self-contained Smart High-Speed Door 10 in a frontal view.
[0077] The illustrated self-contained smart high-speed door 10 is a self-contained smart high-speed door 10 with a fixed segmented door leaf 3 with several connected door leaf segments 11 that can pivot relative to one another. The door leaf 3 or the door leaf segments 11 are movably mounted in two lateral door frames 1, 2 such that the door leaf 3 can slide up and down relative to the door frames 1, 2. For this purpose, corresponding guide rollers (not shown) are slidably mounted in corresponding rails (not shown) in the door frames 1, 2.
[0078] A drive device 4, which is preferably a drive device 4 with a tubular motor, as described with reference to the Fig. 2 and 3 described, is integrated into a door lintel 12 on the top side of the self-contained smart high-speed door 10. An inner shaft 18 of the drive device 4 is mounted in a rotationally fixed manner on the sides of the door lintel 12. A toothed belt 15 runs over toothed pulleys 19 on the right and left side of the drive device 4. In the embodiment shown, the toothed belts 15 are connected to a lowest door leaf segment 11 via corresponding left and right toothed belt connections 14. In addition, the drive device 4 can also have just one toothed pulley 19 with a toothed belt 15. Instead of the toothed pulley 19, a V-belt pulley or a chain pulley or a chain wheel can be used, which are operatively connected to a V-belt or a chain, as well as any other suitable connecting element.
[0079] In the side view of the self-contained smart high-speed door 10, a spiral receptacle 13 for the door leaf 3 in the door head 12 is indicated by a dashed line. Although only one coil of the spiral is indicated, the spiral can have multiple coils, in particular enough coils to accommodate the entire door leaf 13 when the self-contained smart high-speed door 10 is fully opened.
[0080] Although the self-contained smart high-speed door 10 is depicted as a door with a spiral mount for the door leaf, it can also be designed such that the door leaf 13 is pushed vertically upwards out of the door lintel 12 upon opening and runs parallel to a wall in which the self-contained smart high-speed door 10 is installed. Furthermore, versions of the self-contained smart high-speed door 10 are also conceivable in which the door leaf 13 is initially pushed upwards and then changes its direction of movement so that the door leaf 13 runs parallel to a ceiling above the self-contained smart high-speed door 10 when opened.
[0081] The drive device 4 is connected to a direct current energy source 6, which in the side view of the self-sufficient smart high-speed door 10 in Fig. 1 schematically shown as a solar cell module 6 mounted on the outside of the self-sufficient smart high-speed door 10, which is connected to the drive device 4 (or to a DC motor 5 (see Fig. 2 ) of the drive device 4) via an energy buffer, such as a battery (not shown). However, it should be noted that other suitable direct current energy sources are also possible. In particular, the direct current energy source 6 does not have to be attached directly to the self-sufficient smart high-speed door 10, but can, for example, also be mounted on a building roof and connected to the self-sufficient smart high-speed door 10. This allows the self-sufficient smart high-speed door 10 to be operated independently of an external / external energy network (such as a building's power grid). In addition, no current conversion between direct current and alternating current, such as DC-AC conversion or AC-DC conversion, takes place between the direct current energy source 6 and the drive device 4, thereby avoiding converter losses.However, DC-DC power conversion can take place between the energy buffer and the drive device 4, for example, to enable speed ramps and different opening and closing speeds. Such DC-DC power conversion can be controlled via a controller 7. For prior art lifting gates operated with a DC motor 5, AC-DC conversion is always necessary, since such lifting gates are powered by an external power grid, which is usually designed as an AC grid to reduce transport losses. Thanks to the integrated DC power source 6, the self-sufficient smart high-speed door 10 can also be easily retrofitted in buildings that were planned without a lifting gate / high-speed door and therefore do not have the necessary power connections at the required location in the building. This avoids major renovation work on the building's power grid.
[0082] The illustrated self-contained smart high-speed door 10 is equipped with a control panel 16 and a sensor arrangement 17 (shown only schematically as a box). The sensor arrangement 17 can, for example, comprise proximity sensors, speed sensors and acceleration sensors for the door leaf, force sensors for the door leaf, or other sensors. The sensor arrangement 17 can, for example, also comprise sensors for monitoring environmental conditions for big data analysis of service requirement events, as described above. The control panel 16 is communicatively connected to the controller 7 (indicated by a dashed line). An embedded subscriber identification module (eSIM) 20 and / or a WLAN module 30 (collectively referred to below as the communication module) is also connected to the controller 7 and configured to receive control instructions from an external user interface 40 (e.g.a user's smartphone or another mobile device). For this purpose, the controller 7 can be connected to a wireless network (WLAN) via the WLAN module 30 and / or to a cellular network via the eSIM 20. If the external user interface 40 is also connected to the WLAN and / or a cellular network, it can communicate with the controller 7 via the corresponding network. Also, the external user interface does not have to be connected to the same local network as the controller 7. The external user interface 40 can, for example, communicate with a server set up for this purpose via a wide area network (WAN), such as the Internet, which in turn communicates with the controller 7 or is part of the controller 7 itself, which also has access to the WAN.The communication module can also be used to communicate with a higher-level entity as part of the big data analysis described herein.
[0083] The opening and closing of the self-contained smart high-speed door 10 can be controlled either directly via the control panel 16 in a known manner, or via the external user interface 40. It should also be noted that the control panel 16 can also be omitted entirely, and control is then carried out solely via the external user interface 40 or (at least) one external user interface. The external user interface 40 can contain software to receive control instructions from a user and / or to send automatic control commands, as described above (for example, in relation to a geofence application). In this way, the self-contained smart high-speed door implements "smart" functions, such as automatic opening and closing commands as the user approaches and moves away from the self-contained smart high-speed door. Such applications have been described in detail above and are not repeated here for the sake of brevity.
[0084] The controller 7 can also continuously monitor the operating status of the self-contained smart high-speed door 10 and send warning signals to the external user interface 40 when undesirable events occur. For this purpose, the controller 7 can monitor the outputs of the sensors included in the sensor array 17. For example, the controller can detect an attempted break-in if the door leaf moves without previously receiving a control command (indicated by measurements from the speed sensor and the acceleration sensor). Similarly, the controller 7 can detect an emergency, such as a trapped user, if, for example, the output of a force sensor exceeds a certain threshold.In addition, the controller 7 can monitor the power supply from the DC power source 6 (for example, by monitoring a voltage level) and send a warning message to the external user interface 40 in the event of a power shortage. However, this list of undesirable events is merely exemplary, and other undesirable events may also be detected. Where appropriate, the controller 7 can also automatically send warning messages to appropriate authorities, such as the police, ambulances, security companies, etc.
[0085] It should be noted that the control panel 16 and the sensor arrangement 17 can also be mounted at other locations and are not limited to the positions shown.
[0086] With reference to the Fig. 2 and 3 An exemplary drive device for the self-sufficient Smart high-speed door 10 is now shown Fig. 1 described, which is designed as a tubular motor. However, it should be noted that any suitable drive device comprising at least one DC motor 5 can be used in the self-contained smart high-speed door 10.
[0087] The Fig. 3 shows the drive device 4 in a schematic side view. In the top view, elements not visible from the perspective shown are shown with dashed outer contours. Fig. 2 shows a schematic cross-sectional view of the drive device 4 from the Fig. 3 along the section line AA. In general, fixed, i.e., rotationally fixed, connections 22 between two components are schematically represented by crosses in the figures. Rotatable connections 21 are schematically represented by solid dots.
[0088] The illustrated drive device 4 has an inner shaft 18 and an outer hollow shaft 23, which surrounds the inner shaft 18 and is arranged concentrically to the inner shaft 18. The outer hollow shaft 23 is a hollow cylinder or a tube, as best shown in Fig. 3 The inner shaft 18 is a standard elongated shaft. The inner shaft 18 is also designed to be inserted into a door head 12 at its lateral ends (see Fig. 1 ) to be mounted in a rotationally fixed manner. The inner shaft 18 has an inner shaft length 24 and the outer hollow shaft 23 has an inner hollow shaft length 25. The outer hollow shaft 23 is rotatably mounted on the inner shaft 18 at its lateral ends by hollow shaft bearings 26. The hollow shaft length 25 describes the length of the hollow shaft 23 available for accommodating one or more DC motors 5 in the hollow shaft 23, ie the length available between the hollow shaft bearings 26. In the Fig. 3 The hollow shaft bearings 26 are not shown for reasons of clarity.
[0089] An inner motor element 27 surrounds the inner shaft 18 and, as indicated by the crosses shown, is connected to it in a rotationally fixed manner. The inner motor element 27 is surrounded by an outer motor element 28, which is also aligned and arranged concentrically with the inner shaft 18 and the inner motor element 27. The outer motor element 28 is rotatable relative to the inner motor element 27.
[0090] Since the inner shaft 18 in an installed state of the drive device 4 (shown in Fig. 1 ) is non-rotatably mounted in a door lintel 12, the inner motor element 27 is non-rotatably connected to the inner shaft 18, and the outer motor element 28 is rotatably mounted on the inner motor element 27, the inner motor element 27 and the outer motor element 28 form an external rotor motor, which is referred to herein as a DC motor 5. The inner motor element 27 thus functions as the stator of the first DC motor 5. The outer motor element 28 functions as the rotor of the DC motor 5.
[0091] Although in the Fig. 1 bis 3 Not shown, both the inner motor element 27 and the outer motor element 28 can contain either magnetic coils or permanent magnets. It is also possible for both the inner motor element 27 and the outer motor element 28 to be equipped with magnetic coils. However, at least one of the inner motor element 27 and the outer motor element 28 has magnetic coils, so that the DC motor 5 represents an electric motor. As one skilled in the art will readily recognize, the DC motor 5 can be designed in any suitable manner, for example as a DC motor with a commutator. However, other DC motors are also conceivable. In particular, the DC motor 5 in the illustrated embodiment can have a power of approximately 1 kW up to 3 kW and a force of approximately 1.2 kN or more.In particular, the drive device 4 can provide an opening speed of the self-contained smart high-speed door 10 of up to 4 m / s.
[0092] The outer motor element 28 is also firmly connected to the outer hollow shaft 23, as also indicated by crosses. Activation of the DC motor 5 thus causes the outer hollow shaft 23 to rotate. The outer hollow shaft 23 can then be used, for example, to pick up / wind up film-like door leaves 3 when the drive device 4 is installed.
[0093] Furthermore, in the illustrated drive device 4, the inner shaft length 24 is greater than the hollow shaft length 25, whereby the inner shaft 18 has a first lateral projection 31 (relative to the hollow shaft) and a second lateral projection 32 (relative to the hollow shaft). A toothed pulley 19 is rotatably mounted on the inner shaft 18 on the first lateral projection 31 and the second lateral projection 32 and is firmly connected to the outer hollow shaft 23. This arrangement causes the toothed pulleys 19 to rotate when the motor is activated. Each of the toothed pulleys 19 can transmit the motor power to a toothed belt, which, for example, in the case of a self-contained smart high-speed door 10 with fixed, segmented door leaves 3, can be connected to at least one (e.g., the lowest) or all of the door leaf segments 11, in order to raise or lower the door leaf 3 when the DC motor 5 or the drive device 4 is activated, i.e.to open or close the self-contained smart high-speed door 10.
[0094] Although in the Fig. 1 bis 3 While illustrated with two toothed pulleys 19, the drive device 4 can also have just one toothed pulley 19 on one side of the drive device. Furthermore, instead of a toothed pulley 19 with a toothed belt, a V-belt pulley with a V-belt or a chain pulley with a chain can be used, for example. It should also be noted that if the drive device 4 is used for a self-contained smart high-speed door 10 with a film curtain (such as a PVC curtain) as the door leaf 3, it does not include toothed pulleys 19. In this case, the film curtain is wound directly onto the outer hollow shaft 23.
[0095] In the Fig. 2In the embodiment shown, the DC motor 5 extends along the entire hollow shaft length 25, whereby a high torque of the DC motor 5 can be achieved. Such dimensioning of the DC motor 5 is possible in particular due to the space-saving arrangement within the outer hollow shaft 23. However, it should be noted that instead of a DC motor 5 extending over the entire hollow shaft length 25, the drive device 4 can contain a DC motor 5 extending only over part of the hollow shaft length 25 or several, for example, similarly designed, modular DC motors 5. In particular, in the latter embodiment, the power of the drive device 4 can be easily adapted to the respective requirement, for example by pressing several modular DC motors 5 into the outer hollow shaft.
[0096] The drive device 4 can also have a cooling device (not shown). This can be, for example, air cooling or liquid cooling such as water cooling. With air cooling, for example, a fan (not shown) can be attached to one side of the hollow shaft 23 and designed to blow air into the hollow shaft 23. Such a fan can, for example, be arranged outside the toothed disk 19, between the toothed disk 19 and the hollow shaft bearing 26, or inside the hollow shaft bearing 26. To enable an air flow from the outside through the fan into the hollow shaft 23, the hollow shaft bearing 26 and the toothed disk 19 can contain corresponding ventilation openings. In addition, the DC motor 5 can also contain corresponding cooling channels (not shown) that enable an air flow through the DC motor 5.The hollow shaft 23 can also include corresponding air outlet openings (not shown) that allow the heated air to escape from the hollow shaft 23. Alternatively, the DC motor 5 can also be water-cooled. The statements regarding the cooling channels in the DC motor 5 also apply without restriction to any additional DC motors 5 that may be present, as described above.
[0097] It should be noted that although the self-contained smart high-speed door 10 has been described with a drive device 4 in the form of a tubular motor, any other suitable drive device may be used. In particular, drive devices with side-mounted DC motors driving a drive shaft, which in turn is connected to the door leaf by appropriate connecting elements, may also be used.
[0098] Additionally, it should be noted that "comprising" or "having" does not exclude other elements or steps, and "a" or "an" does not exclude a plurality. Furthermore, it should be noted that features or steps described with reference to one of the above embodiments may also be used in combination with other features or steps of other embodiments described above. Reference signs in the claims are not to be considered as limitations. LIST OF REFERENCE SYMBOLS
