Abstract
Description
Technical Field
[0001] The present invention relates to a safety strip for a door, in particular a safety strip for a vehicle door. Furthermore, the present invention relates to a door having the safety strip and a vehicle having the door. Furthermore, the present invention relates to a method for operating a safety element. Background Art
[0002] Safety strips for transport vehicle doors are known in the prior art. These strips are used to seal between a door and a frame, or between two doors. These strips are also known as profiled safety strips. Furthermore, they can prevent or reduce the likelihood of objects (such as people or objects) being trapped between a door and a frame, or between two doors. To this end, the strips can include, for example, contact strips that generate a signal when deformed in a predefined manner. For example, deformation of the strip could be caused by a person's arm being trapped between a closing door and a frame, or between two doors. This signal can interrupt further closing of the door to prevent injury.
[0003] Furthermore, the use of light barrier assemblies is known, which can be used to detect objects between a door and a frame, or between two doors. Light barrier assemblies typically include a transmitter and a receiver. The transmitter can be located in the frame, while the receiver can be arranged in the door. If the light emitted by the transmitter is interrupted by an object, the light barrier assembly generates a signal that can interrupt the closing of the door.
[0004] Object recognition by contact strips and / or light barrier assemblies is limited in many respects. In addition, in particular the transmitting and receiving units of the light barrier assemblies are open towards the monitored space, making them susceptible to damage, for example due to vandalism. Summary of the Invention
[0005] Therefore, the object of the present invention is to provide a security strip that improves object recognition. A further object of the present invention is to provide a security strip that ensures increased security. A further object is to provide a security strip that is protected from damage. A further object is to provide a security strip that is simple and inexpensive to manufacture and / or replace.
[0006] A security strip for a door, preferably a door of a vehicle, is described. The security strip is elastic and / or flexible. The security strip has at least one receiving space.

The sensor assembly is configured to emit electromagnetic radiation into a monitoring area and to receive electromagnetic radiation from the monitoring area. The sensor assembly is arranged in the receiving space such that the security strip completely surrounds the sensor assembly in at least one plane.
[0007] By emitting electromagnetic radiation into and receiving electromagnetic radiation from the monitored space, the monitored space can be effectively monitored and object detection within the monitored space can be improved. The sensor assembly can be positioned in a protected manner within the receiving space. Furthermore, the sensor assembly can be easily installed on a door, such as a vehicle door. This requires only replacing the door's security strip. This provides a simple and inexpensive retrofit option for existing doors.
[0008] The safety strip can be non-rigid, flexible and / or elastic. In particular, the safety strip is configured as a profile and is provided as a safety profile. The safety strip can contribute to or cause a seal between a door and a frame or between a door and another door.

For example, the security strip can be black. The security strip can include a color additive, preferably carbon.
[0018] The security strip may be or can be produced by extrusion or coextrusion.
[0019] The sensor assembly can emit electromagnetic radiation into a monitoring area. The electromagnetic radiation can be reflected in the monitoring area, for example, by an object in the monitoring space, and the reflected electromagnetic radiation can be received by the sensor assembly. Based on the electromagnetic radiation, and in particular, based on the received or reflected electromagnetic radiation, the sensor assembly can determine whether an object is present in the monitoring area.
[0020] Generally, electromagnetic radiation can also be called electromagnetic waves.
[0021] Electromagnetic radiation may be emitted through the security strip. Alternatively or additionally, electromagnetic radiation may be received through the security strip. Electromagnetic radiation may pass through the material of the security strip when being received and / or emitted.
[0022] The sensor assembly can be arranged in the receiving space such that preferably electromagnetic radiation passes through the security strip or the material of the security strip when electromagnetic radiation is received and / or emitted by the sensor assembly.

Alternatively, the multiple planes can be non-parallel and can form an angle of 5°, 10°, or 20° between two of the planes.
[0026] The security strip or its material can substantially completely surround the sensor assembly. This allows one or more data lines, signal lines, and / or power supply lines to be substantially excluded. The security strip or its material can completely surround the sensor assembly, allowing the data lines, signal lines, and / or power supply lines to be excluded. This means that while the sensor assembly is completely surrounded by the security strip, the data lines, signal lines, and / or power supply lines do not necessarily have to be (completely) surrounded by the security strip.

Based on these signals, the controller can determine whether an object is present in the monitored area. The transmission can be wireless or wired.
[0054] The controller can be configured to compile, process, and / or evaluate a signal based on the received electromagnetic radiation. The signal can include or be the sum of all parameters acquired by the sensor assembly. For example, the signal can include all parameters received by the antenna. In particular, one or more filters can be applied to the signal. For example, a background signal can be subtracted or calculated using the filter.

[0056] The controller can be configured to determine the location and / or velocity and / or direction of movement of an object based on electromagnetic radiation received in the monitoring area or based on the compiled, processed, and / or evaluated signals. The velocity can be the relative velocity between the sensor assembly and the object. The location can be determined based on the distance and direction between the sensor assembly and the object. The direction can be determined or defined by a point and one or two angles.
[0057] Preferably, the sensor assembly or the controller is configured to know the location and speed of an object in the monitoring space. Additionally, the sensor assembly or the controller may be configured to know the direction of movement of the object.
[0058] The controller can be configured to interpret the received electromagnetic radiation based on intermediate information.

For example, the "relevance" category can be divided into ["relevant," "not relevant"].
[0060] The controller can be configured to distinguish objects based on electromagnetic radiation and / or based on the compiled, processed, and / or evaluated signals. For example, the controller can identify multiple objects based on electromagnetic radiation and / or based on the compiled, processed, and / or evaluated signals. The controller can be configured to distinguish or separate the (identified) objects.
[0061] The controller may be configured to evaluate or analyze a signal based on the received electromagnetic radiation. For example, the controller may be configured to learn or determine or interpret a scene based on the received signal of the electromagnetic radiation.
[0062] Preferably, the controller is configured to interpret the scenario based on the signals, intermediate information, and / or classification. For example, the controller can be configured to determine whether a person (also known as a passenger) is approaching a closing door. In this case, the controller can determine whether a person is (potentially) trapped between the door and the frame, or between the door and another door.
[0063] The controller can be configured to generate a signal based on electromagnetic radiation and / or based on the compiled signal and / or based on the classification and / or based on the state of the door. The generated signal can alter the operation of the door. Preferably, the signal can alter the movement of the door. More preferably, the signal can interrupt or abort the closing process of the door.
[0064] Preferably, the state of the door, in particular its open and / or closed state, is an influencing variable in generating the signal. If a person or other object moves toward the closing door and the door is significantly open, the controller can be informed that the closing process does not need to be aborted. Conversely, if the door is only slightly open, for example because the closing process is almost complete, the controller can be informed that the closing process must be aborted because a person is about to become trapped between the door and the frame or between the door and another door.
[0065] The controller can be configured to preferably utilize one or more algorithms before generating the signal. In particular, the controller can be configured to apply one or more algorithms to evaluate the signal based on electromagnetic radiation. The algorithm can be configured to learn from data. For example, machine learning can be applied to the algorithm. In particular, supervised machine learning, unsupervised machine learning, and / or reinforcement learning can be applied to the algorithm.

[0096] Figure 1a Door assembly 1000 is shown in a first state. Door assembly 1000 includes a door 300. Door 300 can be a door of a vehicle, such as a train. Door 300 is designed as a single leaf. Door 300 can be designed as a sliding door that operates relative to a frame 500. Door 300 preferably includes a safety strip 200 on one end, which is (slightly) compressed when door 300 impacts frame 500, which can be, for example, an aluminum or steel profile. Door 300 preferably includes a glass pane or window 400. Door 300 can define an xy plane. The z direction can be oriented perpendicular to the xy plane.
[0097] Safety strip 200 includes a sensor assembly 100. Sensor assembly 100 may be arranged in the upper half of safety strip 200 (in the direction of gravity). Preferably, sensor assembly 100 is arranged in the upper third or upper quarter of safety strip 200. Sensor assembly 100 is at least partially, and in particular, completely, surrounded or covered by safety strip 200. Sensor assembly 100 may be a radar sensor assembly.
[0098] exist Figure 1a In the embodiment, the door 300 is closed so that the safety strip 200 rests against the frame 500. When the door 300 is closed, the sensor assembly 100 can be set up so as not to perform measurements.
[0099] exist Figure 1b Shown in Figure 1a The door assembly 1000 is configured to be partially open, wherein the door 300 is partially open. When the door 300 is open, the sensor assembly 100 can be configured to perform measurements. To this end, the sensor assembly 100 can emit electromagnetic radiation into the monitored area and receive electromagnetic radiation from the monitored area.
[0100] The monitoring area is preferably the entrance and / or exit area of door 300. The monitoring area can extend perpendicularly to the plane defined by the door (in one direction and / or in the opposite direction) over a distance of at least 0.1 m or up to at least 3.0 m. This allows the monitoring area to be monitored with respect to subjects, such as people or objects.
[0101] It is provided that the sensor assembly 100 is arranged largely or even completely in the safety strip 200. The sensor assembly 100 is thereby protected from damage, dust and other environmental influences.
[0102] exist Figure 1bIn the example, object 800 is present in the monitoring area. Sensor assembly 100 emits electromagnetic radiation into the monitoring area (also referred to as the monitoring space). The electromagnetic radiation may be reflected by object 800. The reflected electromagnetic radiation is received by sensor assembly 100. Object 800 can be identified based on the received electromagnetic radiation. Furthermore, the distance of object 800 from sensor assembly 100 can be identified or determined based on the received electromagnetic radiation. Similarly, the speed of object 800 (relative to sensor assembly 100) can be identified or determined based on the received electromagnetic radiation. The direction in which object 800 (relative to sensor assembly 100) is moving can also be identified or determined based on the received electromagnetic radiation. Using at least one or more of these parameters, it can be determined whether object 800 is (possibly) trapped during the closing process of door 300. Based on one or more of these parameters, it can be determined whether there is a risk or probability of object 800 being trapped.
[0103] When a pinching event is detected or a threshold value for the probability of pinching is exceeded, the closing process of door 300 can be suspended or interrupted. Sensor assembly 100 can generate a signal. This signal can be transmitted to the control unit of door 300. In response to the signal, the control unit of door 300 can change the control of door 300, for example, suspending or interrupting the door closing process as described above.
[0104] In order to determine or know whether an object is (possibly) caught between the door 300 and the frame 500 during the closing process of the door 300, the characteristics and / or state of the door 300 may be considered. Similarly, in order to determine or know whether a signal for changing the control of the door is generated, the characteristics and / or state of the door 300 may be considered.
[0105] Characteristics of door 300 include, for example, its closing speed or closing force. When the closing speed is high, it is possible to predict or detect that an object will be trapped, even when the known distance is greater, compared to when the closing speed is low. When the closing force is high, the consequences of trapping (e.g., risk of injury to a person) are high, so sensor assembly 100 generates a signal for controlling door 300 even when the risk of trapping or the probability of trapping is low.
[0106] The state of door 300 is, for example, the degree of opening of door 300. Compared to when door 300 is more open, when door 300 is less open, it can be detected that object 800 is about to be pinched or has a higher probability of being pinched when the distance and movement of object 800 from sensor assembly 100 are the same.
[0107] exist Figure 2a The door assembly 1000 is shown in FIG. The door assembly 1000 is similar to Figure 1a and 1b A door assembly, wherein Figure 2aThe door assembly 1000 includes two doors 300, 301. Each of the doors 300, 301 can be any door disclosed herein.
[0108] The doors 300, 301 can be doors of a means of transport, such as a train or a bus. The doors 300, 301 are designed in two leaves. The doors 300, 301 can be configured as sliding doors.
[0109] The first door 300 includes a safety strip 200. A sensor assembly 100 is arranged in the safety strip 200. Figure 1a and Figure 1b The first door 300 may have a glass pane or window 400 .
[0110] The second door 301 includes a security strip 201. A sensor assembly 101 is arranged in the security strip 201. The second door 301 may have a glass pane or window 401. The second door 301 may be any door disclosed herein.
[0111] exist Figure 2a In the embodiment shown in FIG. 3 , the doors 300 and 301 are closed. In the closed state, the safety strips 200 and 201 of the first and second doors 300 and 301 are in contact. The two safety strips can be (slightly) compressed by contact.
[0112] exist Figure 2b 1 shows the door assembly 1000 in an open state. The sensor assembly 100 of the first door 300 and / or the sensor assembly 101 of the second door 301 emit electromagnetic radiation into the monitoring area. An object 800 may be present in the monitoring area. The electromagnetic radiation may be reflected by the object 800. The radiation reflected by the object 800 may be received by the sensor assembly 100 of the first door 300 and / or the sensor assembly 101 of the second door 301. Objects may be identified based on the electromagnetic radiation, preferably in view of Figure 1a and 1b In particular, the sensor assembly 100 of the first door 300 and / or the sensor assembly 101 of the second door 301 can learn or determine the position or location, the distance between the respective sensor assembly and the object, the speed of the object (relative to the respective sensor assembly) and / or the direction of movement of the object (relative to the respective sensor assembly).
[0113] Each of the sensor assemblies 100, 101 can generate a signal for controlling the respective door 300, 301. The movement of the respective door 300, 301 can be changed based on the signal or signals. Likewise, the movement of the first and second doors 300, 301 can be changed based on the signal of only one of the sensor assemblies 100, 101.
[0114] Figure 3aA schematic cross section through the safety strip 200 is shown. Figure 3a A schematic cross section through a section of door 300 is also shown.
[0115] The door 300 may include a fastening receptacle 310. The safety strip 200 may be inserted into the fastening receptacle 310 to connect the safety strip 200 to the door 300. This connection may be force-locking and / or form-locking. The connection may be removable. The door 300 may have a first side 320 and a second side 330 on the end side. The door 300 may also preferably have a first protrusion 340 and a second protrusion 350 on the end side of the door 300. The fastening receptacle 310 may be formed between the first side 320 and the second side 330. The first protrusion 340 and the second protrusion 350 may bring about a form-locking connection with the safety strip 200, in particular in the direction of the end side to which the safety strip 200 is attached.
[0116] The security strip 200 may include a fastening section 240. The fastening section 240 may be configured to complement the fastening receptacle 310. The fastening section 240 may be push-fit or press-fit into the fastening receptacle 310 to connect the security strip 200 to the door 300. The fastening section 240 may be dovetail-shaped. The connection between the security strip 200 and the door 300 may be a dovetail connection. The security strip 200 may be connected to the door 300 along its entire length.
[0117] The security strip 200 may have a first receiving space 210. The first receiving space 210 may extend along the entire length of the security strip 200. Alternatively, the first receiving space 210 may extend along the length of the security strip 200, at most in sections. In particular, the first receiving space 210 is open on both sides or at most on one side, with one or more openings preferably present at the axial ends (in the longitudinal direction). Perpendicular to the longitudinal extent of the security strip 200, the first receiving space 210 may be closed, i.e., have no openings, or be completely surrounded by the security strip 200 or its material.
[0118] The security strip 200 may have a second receiving space 220. The second receiving space 220 may extend along the entire length of the security strip 200. Alternatively, the second receiving space 220 may extend along the length of the security strip 200, at most in sections. In particular, the second receiving space 220 is open on both sides or at most on one side, with one or more openings preferably present at the axial ends (in the longitudinal direction). Perpendicular to the longitudinal extent of the security strip 200, the second receiving space 220 may be closed, i.e., have no openings, or be completely surrounded by the security strip 200 or its material.
[0119] The security strip 200 may include a third accommodating space 250. The third accommodating space 250 may extend along the entire length of the security strip 200. Alternatively, the third accommodating space 250 may extend along the length of the security strip 200, at most in sections. In particular, the third accommodating space 250 is open on both sides or at most on one side, preferably with one or more openings located at the axial ends (in the longitudinal direction). The third accommodating space 250 may have at least one opening, preferably at least two or three openings, perpendicular to the longitudinal extent of the security strip 200.
[0120] The security strip 200 may have a cavity 230. The cavity 230 may extend along the entire length of the security strip 200. Alternatively, the cavity 230 may extend along the length of the security strip 200 in sections, at most. In particular, the cavity 230 may be open on both sides or at most on one side, with one or more openings preferably present at the axial ends (in the longitudinal direction). Perpendicular to the longitudinal extent of the security strip 200, the cavity 230 may have at least one opening, preferably at least two or three openings. Perpendicular to the longitudinal extent of the security strip 200, the cavity 230 may have at least one opening, preferably at least two or three openings. Perpendicular to the longitudinal extent of the security strip 200, the cavity 230 may be closed, i.e., have no openings, or be completely surrounded by the security strip 200 or its material. Similarly, the cavity 230 may be completely closed, i.e., have no openings or be completely surrounded by the security strip 200 or its material.
[0121] exist Figure 3b 3 shows the security strip 200 in a state connected to the door 300. The fastening section 240 of the security strip 200 can be arranged in the fastening receptacle 310 of the door 300.
[0122] Sensor assembly 100 is disposed in first accommodation space 210. Due to the design of first accommodation space 210, when sensor assembly 100 emits electromagnetic radiation into the monitoring area, the electromagnetic radiation passes through security strip 200 or the material of security strip 200. Accommodation space 210 is particularly disposed between the fastening area of security strip 200 and the contact area of security strip 200. This ensures that sensor assembly 100 is securely accommodated and further safeguards other functions of security strip 200. When sensor assembly 100 receives electromagnetic radiation, electromagnetic radiation from or from the monitoring area can pass through security strip 200 or the material of security strip 200. Preferably, first accommodation space 210 is configured in security strip 200 so that electromagnetic radiation from sensor assembly 100 to the monitoring area and / or from the monitoring area to sensor assembly 100 passes only (i.e., exclusively) through the material of security strip 200 or security strip 200. If further elements are arranged in the path of the electromagnetic radiation between the sensor assembly 100 and the monitoring area, a portion of the electromagnetic radiation may be absorbed and / or reflected, thereby possibly falsifying the measurement.
[0123] A contact strip 270 may be arranged in the second receiving space 220. A cavity 230 may be formed in front of the second receiving space 220, toward the end of the door 300 or the contact area of the security strip 200, particularly toward the end of the door 300 where the security strip 200 is arranged or connected. The cavity 230 in front of the second receiving space 220, in which the contact strip 270 is arranged, facilitates deformation of the security strip 200 or its material, thereby enabling the contact strip 270 to be triggered with less force than would be the case without the cavity 230. When the contact strip 270 is triggered, at least one section of the security strip 200 is compressed, thereby creating the possibility of an object being trapped or potentially trapped. After being triggered, the contact strip 270 can transmit a signal to a control unit of the door 300, which, based on this signal, modifies the movement of the door 300, for example, interrupting or aborting the closing process.
[0124] A light barrier assembly 280 may be disposed in the third storage space 250. The light barrier assembly 280 may be arranged in the third storage space 250 so as to transmit light, preferably within a wavelength range invisible to humans, into the monitored area. A light receiver may be provided on a frame or door opposite the light barrier assembly 280. If light reception is interrupted, for example, by an object in the monitored area, the light barrier assembly 280 may be triggered. When triggered, the light barrier assembly 280 may transmit a signal to the control unit of the door 300, which, based on the signal, may alter the movement of the door 300, for example, interrupting or aborting the closing process.
[0125] The contact strip 270 , the grating assembly 280 , the second receiving space 220 , the third receiving space 250 and / or the cavity 230 are optional.
[0126] Figure 4 Sensor assembly 100 is schematically shown. Sensor assembly 100 may include a receiving assembly 110. Receiving assembly 110 may include at least one antenna, preferably at least two antennas, more preferably at least three antennas, and even more preferably at least four antennas. Each of antennas R1, R2, R3, and R4 may receive electromagnetic radiation from or from a monitored area.
[0127] In the receiving component 110, a spacing sR1 can exist between each two of the antennas R1, R2, R3, and R4 in a first direction, which spacing is between 0.1 and 0.9 times the wavelength of the electromagnetic radiation, or particularly preferably approximately half (approximately 0.5 times the wavelength of the electromagnetic radiation). Alternatively or additionally, a spacing sR2 can exist between each two of the antennas R1, R2, R3, and R4 in a second direction, which spacing is between 0.1 and 0.9 times the wavelength of the electromagnetic radiation, or particularly preferably approximately half (approximately 0.5 times the wavelength of the electromagnetic radiation). The first direction may not be parallel to the second direction, and in particular may be perpendicular to the second direction.
[0128] The sensor assembly 100 may include a transmitting assembly 120. The transmitting assembly 120 may include at least one antenna, preferably at least two antennas, and more preferably at least three antennas. Each of the antennas T1, T2, and T3 may transmit electromagnetic radiation to a monitoring area.
[0129] In the transmitting assembly 120, a spacing sT1 can exist between each two of the antennas T1, T2, and T3 in a first direction. This spacing is between 0.6 and 1.5 times the wavelength of the electromagnetic radiation, or particularly preferably approximately one time (approximately 1.0 times the wavelength of the electromagnetic radiation). Alternatively or additionally, a spacing sT2 can exist between each two of the antennas T1, T2, and T3 in a second direction. This spacing is between 0.6 and 1.5 times the wavelength of the electromagnetic radiation, or particularly preferably approximately one time (approximately 1.0 times the wavelength of the electromagnetic radiation). The first direction may not be parallel to the second direction, and in particular, may be perpendicular to the second direction.
[0130] Sensor assembly 100 may include a controller 130. Controller 130 may be configured to control sensor assembly 100. In particular, controller 130 may be configured to control transmitting assembly 120. The emission of electromagnetic radiation into the monitored area may be controllable via controller 130. In particular, the controller may receive a signal from another control unit that signals the start of an opening or closing process for one or more doors and the need to activate sensor assembly 100. Controller 130 may be configured to interpret and / or evaluate signals from receiving assembly 110. Alternatively, controller 130 may be external to sensor assembly 100.
[0131] Sensor assembly 100 may include an energy supply 140. Energy supply 140 can supply energy, particularly electrical energy, to sensor assembly 100. Energy supply 140 may include a battery or accumulator. Energy supply 140 may be configured to receive electrical energy wirelessly, for example, by induction. Alternatively or additionally, energy supply 140 may be connected to an energy source, preferably outside of safety strip 200. This connection may be a contact-type connection, such as a wired connection.
[0132] The sensor assembly 100 may include a data interface 150. The data interface 150 may be configured to transmit data to the exterior of the security strip 200, either contactlessly or with contact. Alternatively or additionally, the data interface 150 may be configured to receive data from the exterior of the security strip 200, either contactlessly or with contact. In particular, the data interface 150 is connected to a door control unit.
[0133] Sensor assembly 100 may include memory 160. Memory 160 may include volatile and / or non-volatile memory. Memory 160 may store data from receiving assembly 110. Memory 160 may store one or more algorithms for evaluating data in memory 160, particularly data from receiving assembly 110.
[0134] Figures 5a to 5d The measurements of the sensor assembly 100 of the door assembly 1000 are shown. Figure 5a In the embodiment, at least one door, in particular both doors, is open. The sensor assembly 100 transmits electromagnetic waves into the monitoring area and receives electromagnetic radiation from or from the monitoring area. There is no object (to be detected) in the monitoring area.
[0135] The measurement situation is Figure 5b and Figure 5c Visualization in. Figure 5b A graphic representation of received electromagnetic radiation is shown. Here, the angle in degrees (°) is plotted against the distance in meters (m). Different signal strengths in decibels (dB) are represented by differently colored areas or by different shades of light. Figure 5b In the example, the angle is the azimuth.
[0136] exist Figure 5b Several areas of relatively high signal strength can be seen in the image. These areas are caused by reflections of the electromagnetic radiation emitted by sensor assembly 100. For example, at a distance of approximately 1.6 m, area 810 with high signal strength is formed in an azimuth angle range of approximately -20° to over 80°. This area may be caused by reflections of electromagnetic radiation at the bottom of the door, such as on the floor of a bus or train. Furthermore, at a distance of approximately 0.7 m, area 820 with high signal strength is formed in an azimuth angle range of approximately -40° to approximately 30°. This area may be caused by reflections of electromagnetic radiation from gripping elements in the door area (e.g., gripping rods).
[0137] Figure 5c Shows something like Figure 5b , where Figure 5c In , the angle is the elevation angle. Figure 5c Again, multiple areas with higher signal strengths are visible. For example, area 811 with high signal strength is formed at a distance of approximately 1.6 m and an elevation angle range of approximately 0° to over 80°. This area can again be caused by reflections of electromagnetic radiation at the door bottom.
[0138] exist Figure 5d Shown in the Figure 5b and 5c The diagram, in Figure 5d In the diagram, velocity in meters per second (m / s) is plotted against distance in meters (m). The diagram uses the term "Doppler" because velocity measurements are based on the Doppler effect. Figure 5d In the scene, only low speeds (negative and positive speeds) are visible.
[0139] like Figures 5b to 5d The signal shown can be regarded as background. When there is no object 800 to be detected in the monitoring area, that is, the monitoring area does not have an object 800 to be detected, the measurement performed by the sensor assembly 100 is as follows: Figures 5b to 5d This background can be subtracted or taken into account in further measurements in order to improve the recognition of the object to be detected. The background cannot be the object to be detected.
[0140] Figures 6a to 6d 1 shows a measurement of the sensor assembly 100, wherein an object 800 to be detected is present in the monitoring area. The object 800 is moving away from the sensor assembly 100. Figure 6b As can be seen in the diagram relative to Figure 5bThe illustration shows an additional region 800b with a higher signal strength. Region 800b is formed at a distance of approximately 0.6 m and an azimuth angle range of approximately -25° to approximately 0°. Region 800b is caused by reflection of electromagnetic radiation from object 800 to be detected.
[0141] Similarly, in Figure 6c It can be seen that relative to Figure 5c The illustration shows an additional region 800c. This region is formed at a distance of approximately 0.6 m and an elevation angle of approximately 0° to approximately 60°. Region 800c is again caused by reflection of electromagnetic radiation at object 800 to be detected.
[0142] exist Figure 6d In FIG. 8 , at a distance of approximately 0.6 m and a speed of approximately 0.5 m / s, a region 800d with increased signal strength is formed, which is due to the reflection of electromagnetic radiation from the object to be detected 800. A positive speed indicates that the object 800 is moving away from the sensor assembly 100.
[0143] Figures 7a to 7d The diagram shows a measurement of the sensor arrangement 100 , wherein an object 800 to be detected is present in the monitoring area. The object 800 is moving in the direction of the sensor arrangement 100 , ie the object 800 is moving towards the sensor arrangement 100 .
[0144] exist Figure 7b In FIG. 8 , region 800b is at a distance of about 0.4 m and an azimuth angle ranging from about -60° to about 20°. Figure 7c In FIG. 8 , a region 800 c can be seen at a distance of about 0.4 m and an elevation angle range of about 0° to over 80°, and in FIG. Figure 7d Region 800d can be seen at a distance of approximately 0.4 m and a velocity of approximately -0.5 m / s. Regions 800b, 800c, and 800d are caused by the object to be detected. The negative velocity indicates that object to be detected 800 is moving in the direction of sensor assembly 100, i.e., toward sensor assembly 100.
[0145] The measurements of sensor assembly 100 can determine the location of object 800, the distance of object 800 from sensor assembly 100, the speed of object 800 relative to sensor assembly 100, and / or the direction of movement of object 800 relative to sensor assembly 100. This allows particularly good monitoring of the monitoring area.
[0146] In principle, the measurement can be performed using the following steps. The controller can be configured to perform the following steps. One or more of the steps may be optional.
[0147] The sensor assembly can emit electromagnetic radiation with at least one antenna (transmitting antenna), preferably over a wide solid angle range. The solid angle range can be at least 30°, at least 45°, at least 60°, at least 75°, or at least 90°.
[0148] The sensor assembly can receive the reflected electromagnetic radiation using at least two antennas (receiving antennas), each of which can be a transmitting antenna and / or a receiving antenna.
[0149] Signal conditioning can be applied to the received electromagnetic radiation, in particular to a signal based on the received electromagnetic radiation. The signal conditioning can include one or more filters. The signal can include, for example, all parameters for different receiving antennas.
[0150] The received signal can be parsed based on intermediate information. Intermediate information is, for example, distance, angle, speed and / or signal strength and / or another possible abstract parameter. Parameters can allow subsequent classification of objects with respect to their type, state and / or their relevance and / or another category. Exemplary parameters are "type", "state" and / or "relevance" and / or another category. These categories can be divided into at least two subcategories. For example, "type" can be decomposed into, for example, ["person", "door"], or, for example, "state" can be decomposed into, for example, ["movement toward door", "movement away from door", "not moving"], or, for example, "relevance" can be decomposed into, for example, ["relevant", "irrelevant"].
[0151] For example, based on the direct and / or abstract intermediate information generated from the previously described steps, the application scenario and / or the classification of objects in the scenario can be analyzed. The scenario can then be interpreted. A signal describing the scenario can be triggered, for example, by a controller. For example, upon monitoring a closing door and an approaching person, the signal can be used to abort the door closing process. The scenario can be interpreted using an algorithm. Algorithms that learn from data can be used to interpret the scenario. In particular, machine learning, such as supervised machine learning, unsupervised machine learning, and reinforcement learning, can be used for learning.
[0152] Figure 8a A door 300 having a security strip 200 is shown. The sensor assembly 100 is arranged in the security strip 200. The door 300 is Figure 8a . The top view shows the door in a plane perpendicular to the direction of gravity or parallel to the floor.
[0153] When sensor assembly 100 emits electromagnetic radiation, monitoring area 900 is obtained. Sensor assembly 100 can be designed to emit electromagnetic radiation within a large solid angle or solid angle range. This allows for particularly effective monitoring of the entry and / or exit area because the monitored area is relatively large. The solid angle or solid angle range can be at least 30°, at least 45°, at least 60°, at least 75°, or at least 90°. The solid angle or solid angle range can extend perpendicular to the direction of gravity or parallel to the floor.
[0154] exist Figure 8b Two door assemblies are shown. The door assembly is shown in a side view. The side view can be perpendicular to the floor or parallel to the direction of gravity.

[0156] Sensor assembly 100 of first door 300 and sensor assembly 101 of second door 301 can emit electromagnetic radiation into respective monitoring areas 900, 901. Each sensor assembly 100, 101 can emit electromagnetic radiation into the monitoring area over a large solid angle or solid angle range. The solid angle or solid angle range can be at least 30°, at least 45°, at least 60°, or at least 75°. The solid angle or solid angle range can extend in the direction of gravity or perpendicular to the ground.
[0157] At least one of the monitoring areas 900 , 901 or each of the monitoring areas 900 , 901 may extend over at least 30%, preferably at least 50%, more preferably at least 70%, more preferably at least 80% of the total height or total length of the respective security strip 200 , 201 .
[0158] Monitoring areas 900 , 901 can extend from security strips 200 , 201 , in which the associated sensor assemblies 100 , 101 are arranged, to an opposite frame or an opposite door.
