CABIN FOR AN AIRCRAFT WITH A SURVEILLANCE ARRANGEMENT, AIRCRAFT WITH THE CABIN, SURVEILLANCE ARRANGEMENT AND METHOD FOR SURVEILLING AN AIRCRAFT CABIN

Description

[0001] The invention relates to a cabin for an aircraft with a monitoring arrangement for monitoring a first monitoring area and a second monitoring area. The invention further relates to an aircraft with the cabin and a method for monitoring a cabin of an aircraft.

[0002] Aircraft are already known in which monitoring systems for seat monitoring are used. For example, the document DE 10 2006 042 299 A1 describes a conditional warning and reporting system for an aircraft cabin to determine the cabin status. Within the scope of a monitoring method for monitoring a seat status, the occupancy status of a seat element is measured using a seat occupancy sensor and the seat belt fastening status of the seat element is measured using a seat belt fastening sensor and transmitted to a monitoring device. This device can generate a warning signal when a combination of a predetermined seat occupancy and seat belt fastening status occurs.

[0003] US 2020 / 169844 A1 discloses systems and methods for providing navigation guidance to people in crowded and unfamiliar environments such as aircraft cabins, stadiums, and theaters. An "activation array" can be created to dynamically activate various lighting devices, personal electronic devices, and / or other devices to guide the person from a current location to a destination, such as a seat, entrance, or restroom. These techniques can be adapted based on existing environmental conditions and / or user-personalized settings to improve the comfort of people in these environments.

[0004] The object of the invention is to provide a cabin with a functionally expanded monitoring arrangement. This object is achieved by a cabin for an aircraft with a monitoring arrangement having the features of claim 1, by an aircraft with the cabin according to claim 7, and by a method for monitoring a cabin of an aircraft having the features of claim 8. Preferred or advantageous embodiments of the invention emerge from the claims, the description, and / or the accompanying figures.

[0005] A cabin for an aircraft, particularly for civil aviation, is proposed. For example, the cabin is designed as a passenger cabin with at least one lavatory and / or at least one entrance door through which the aircraft and / or the cabin can be entered.

[0006] The cabin has a first monitoring area and a second monitoring area. The cabin comprises a monitoring arrangement. The monitoring arrangement is designed to monitor the first monitoring area and the second monitoring area. Preferably, the monitoring arrangement is designed to monitor and / or control a flow of people in the cabin. In particular, the monitoring arrangement is designed to monitor and control how many people are located at which position in the first monitoring area and in the second monitoring area and / or how many people are located in the first and / or second monitoring area.

[0007] The monitoring arrangement comprises at least one output device. The at least one output device is designed and / or arranged to output an approval signal or a prohibition signal regarding a change in the position and / or presence of at least one person in the first monitoring area and / or in the second monitoring area. Preferably, the approval signal can be outputted / is outputted by the at least one output device when a change in the position and / or presence of at least one person in the first monitoring area and / or in the second monitoring area is permitted or authorized. In particular, the prohibition signal can be outputted / is outputted by the at least one output device when a change in the position and / or presence of at least one person in the first monitoring area and / or in the second monitoring area is prohibited or inadmissible.

[0008] It is advantageous that the flow of people in the cabin, which may be formed by passengers, crew, and / or flight attendants staying and / or moving around the cabin, can be regulated by issuing the release signal or the prohibition signal. This ensures that the necessary distances between people are maintained, for example, to prevent the spread of infection between people. In particular, gatherings of several people in confined areas of the cabin can be avoided.

[0009] In a preferred embodiment of the invention, the release signal and / or the prohibition signal is or comprises an optical signal. Optionally, the output device is designed as a light. Preferably, the light emits the optical signal in the form of light and / or outputs the optical signal as a symbol, in particular as an illuminated symbol. In particular, the light can be an on-off light, which can display either the prohibition signal or the release signal. It is preferred that the light displays the prohibition signal. When this goes out, it indicates permission to change the position and / or the presence of the at least one person in the respective monitored area.

[0010] Within the scope of the invention, it is particularly preferred that the output device is designed as a traffic light. The traffic light is preferably designed to display a first signal color as the release signal. The first signal color can be, for example, the color green. In particular, the traffic light is designed to display a second signal color as the prohibition signal. The second signal color can be, for example, the color red. The output device as a traffic light can optionally display a third signal color. The third signal color can be, for example, the color orange. The third signal color preferably symbolizes a wait signal, which indicates to the at least one person that the prohibition signal or the release signal will extinguish shortly.

[0011] Optionally, the output device is additionally designed to output at least one acoustic signal in addition to the optical signal. The acoustic signal can be, for example, a noise, a tone, a sequence of tones or a voice message. It can alert the at least one person to the output of the optical signal and thus prevent the prohibition signal and / or the release signal from being overlooked. Preferably, the acoustic signal, for example in the form of an advisory tone, sounds at the same time or almost simultaneously with the display of the optical signal. It is also possible for the acoustic signal to be matched to the displayed optical signal. In particular, a prohibition advisory tone sounds when the prohibition signal is displayed and a different release advisory tone sounds when the release signal is displayed.

[0012] The cabin comprises a seating area with several seats. Preferably, passengers of the aircraft can take their seats on the seats. The monitoring arrangement comprises several output devices. Exactly one output device is assigned to all seats in the seating area. Preferably, the respective output device is arranged above the seat in the cabin. For example, the output device is integrated into the supply duct of the cabin, which is arranged in particular in an overhead area of ​​the assigned seat. In particular, ventilation openings and / or displays such as fasten seat belt signs can also be integrated into the supply duct and / or overhead area. The person sitting on the respective seat can thus clearly recognize the release signal or prohibition signal issued by the output device.

[0013] The first surveillance area comprises at least one aisle located between the seats in the seating area and / or extending between them. In particular, passengers of the aircraft move from their seats through the aisle to reach at least one lounge and / or functional area of ​​the aircraft and from the lounge and / or functional area to return to their seats.

[0014] The second monitoring area comprises the aircraft's lounge and / or functional area. This can, for example, be at least one cabin lavatory and / or at least one waiting area in front of the lavatory. Alternatively, or optionally, the lounge and / or functional area can comprise an entrance and / or exit area of ​​at least one cabin door.

[0015] The cabin includes at least one additional monitoring area. The at least one additional monitoring area includes several or all seats in the seating area.

[0016] The monitoring arrangement comprises a first sensor device. The first sensor device is designed and / or arranged to detect the presence and / or position of at least one person in the first monitoring area as first sensor data. Preferably, the first sensor(s) are designed and / or arranged to detect whether at least one person is in and / or walking along the at least one aisle between the seats in the seating area. For this purpose, the first sensor(s) can be integrated, for example, in a cabin ceiling and / or cabin wall. Alternatively or optionally additionally, the first sensor(s) can be integrated in the area of ​​an overhead luggage compartment and / or in a lateral seat structure of several or all seats, in particular one directed towards the at least one aisle.

[0017] The monitoring arrangement comprises a second sensor device. The second sensor device is designed and / or arranged to detect the presence and / or position of at least one person in the second monitoring area as second sensor data. For example, the second sensor device comprises one or more second sensors. The at least one further sensor device is designed to detect a position and / or presence of at least one person in the at least one further monitoring area as further sensor data. Preferably, the second sensors are designed and / or arranged to detect whether at least one person is in the at least one further lounge and / or functional area of ​​the cabin, in particular in the at least one lavatory, in the waiting area in front of the respective lavatory and / or in the entrance and / or exit area of ​​the aircraft door. The second sensor(s) can, for example,be integrated into a cabin ceiling and / or cabin wall, in the waiting area, in the washroom, and / or in the entrance and / or exit area. Alternatively, or optionally, the second sensor(s) can be arranged on an access door to the washroom and / or on equipment in the corresponding areas.

[0018] The monitoring arrangement comprises at least one further sensor device. The at least one further sensor device is designed and / or arranged to detect the presence and / or position of at least one person in the at least one further monitoring area as further sensor data. For example, the at least one further sensor device comprises a plurality of further sensors. Preferably, one or more of the further sensors are assigned to exactly one seat in the seating area. In particular, the further sensors are designed and / or arranged to detect seat occupancy of the respective seat. The further sensor(s) can be integrated for this purpose as pressure sensors, for example in a seat cushion of the respective seat. It is also possible within the scope of the invention for the further sensor(s) to be designed as distance sensors, for example so-called time of flight sensors, above the seat or row of seats, for exampleare arranged in a supply channel (Passenger Supply Channel, PSC).

[0019] The monitoring arrangement has an evaluation device. The evaluation device is, for example, a microcontroller. The evaluation device is designed to calculate a distance between at least one person in one of the monitoring areas and at least one other person in another of the monitoring areas. In particular, the evaluation device is designed to calculate the distance between the at least one person and the at least one other person based on the first sensor data, the second sensor data, and / or the further sensor data.

[0020] In a further preferred implementation of the invention, the evaluation device is designed to evaluate the occupancy of the seats based on the additional sensor data. In particular, the seat occupancy makes it possible to determine which seats in the seating area are occupied by a person, e.g., a passenger, a crew member, and / or a member of the flight crew, and which are unoccupied.

[0021] For example, the evaluation device is integrated into a mobile computer, for example in a tablet or smartphone, or can be connected and / or connectable to it by cable or wireless means. Alternatively, the evaluation device can be integrated into a permanently installed computer or can be connected and / or connectable to it by cable or wireless means. The computer preferably has a display or screen. In particular, the seat occupancy and / or the calculated distances can be called up and / or displayed on the display or screen. It is also possible within the scope of the invention to display an overview of how often and / or to which seats the prohibition signal or the approval signal is issued.

[0022] The evaluation device, designed as a computer, can be assigned to and / or used by, for example, cabin crew and / or an aircraft crew. The advantage is that, based on the displayed seat occupancy and / or distances, the cabin crew and / or the crew can obtain a quick and reliable overview of how many passengers are already seated and / or in which rows these seats are located. In particular, the cabin crew and / or the crew can obtain information about the flow of passengers in the cabin and, if necessary, take appropriate measures to maintain the necessary distances between passengers and / or avoid congestion.

[0023] Within the scope of the invention, it is particularly preferred that the at least one output device for outputting the release signal and / or the prohibition signal can be controlled by the computer. For this purpose, the computer is connected to the at least one output device, e.g., via WiFi or Bluetooth. In particular, the on-board personnel and / or the crew can control the at least one output device by means of the computer to output the prohibition signal or the release signal for one, some, or all of the seats. In particular, the on-board personnel and / or the crew can control the flow of people in the cabin by outputting the release signal or the prohibition signal based on the seat occupancy and / or distances output on the display or screen. For example, by controlling the prohibition signal, it can be prevented that passengers get up from their seats after landing and step into the aisle before the aircraft has reached its final parking position and has come to a standstill.

[0024] For example, the on-board personnel and / or the crew can use the computer to control the release signal for specific seats and / or rows of seats in the seating area, e.g. initially for the outermost seat in every third row. The on-board personnel and / or the crew can then control the release signal, e.g. for a middle seat in every third row and then for a rear seat in every third row. Individual seats in other rows can then successively receive the release signal, for example. By successively issuing the release signal for specific seats and rows of seats, the necessary distance between passengers can be regulated and maintained, e.g. during disembarkation. This can prevent all passengers from getting up from their seats at the same time, stepping into the aisle and / or searching for their luggage, particularly during disembarkation.In particular, it can prevent all passengers from moving simultaneously or in close succession along at least one aisle to the aircraft door. This makes disembarkation more relaxed and safer for passengers, as well as for the crew and / or cabin crew.

[0025] The on-board personnel and / or the crew have in particular the possibility of exerting influence by controlling the at least one dispensing device in a situation-adapted manner and of preventing congestion and queues in the at least one aisle, e.g. when passengers are boarding or disembarking, and / or crowds in the at least one other lounge and / or functional area.

[0026] The monitoring arrangement comprises a control device. The control device is connectable and / or connected to the evaluation device for signaling purposes. In particular, the evaluation device transmits the calculated distance as distance signals to the control device. The control device is preferably designed to control the at least one output device depending on the calculated distance to output the prohibition signal or the release signal. A control algorithm for control by the control device is stored in the control device and / or in the at least one output device. In particular, the output device can be controlled algorithm-based and / or manually, using the computer operated by the on-board personnel and / or the crew, to output the release signal or the prohibition signal.

[0027] It is advantageous that the flow of people in the cabin can be controlled automatically, in particular according to the stored algorithm, by calculating the distance and issuing the release signal or the prohibition signal depending on this, in particular in the first and second monitoring areas and optionally additionally in the at least one further monitoring area. This advantageously ensures that people in the individual monitoring areas maintain a sufficient distance from one another, in particular to prevent the spread of infection, for example in the event of a pandemic. Furthermore, a gathering of people in certain areas of the cabin and the associated long waiting times, for example in the waiting area in front of the washroom, can be prevented.

[0028] In a preferred embodiment of the invention, the evaluation device is connectable and / or connected to an external device. The external device is assigned, for example, to an external location, such as ground staff of the aircraft. Preferably, the evaluation device is designed to transmit the seat occupancy of the seats in the seating area and / or the calculated distance between the people in the monitoring areas to the external device. By outputting this information(s), a boarding process before the aircraft takes off can be supported by the external location, for example. In particular, the external device can output how many people are currently boarding the aircraft, how many people have already taken their seats and / or how many people are in the aisle or in the at least one other common and / or functional area of ​​the cabin.This prevents several people from standing together in a confined space and / or long queues from forming. In particular, it ensures passengers' comfort when boarding the aircraft and protects them from the risk of infection.

[0029] A monitoring arrangement for monitoring a cabin of an aircraft is designed for integration and / or use in the cabin according to the previous description and / or according to one of claims 1-6.

[0030] The monitoring arrangement comprises a first sensor device. The first sensor device has a plurality of first sensors. The first sensor device and / or the first sensors are configured to detect a position and / or presence of at least one person in a first monitoring area of ​​the cabin as first sensor data.

[0031] The monitoring arrangement comprises a second sensor device. The second sensor device has one or more second sensors. The second sensor device and / or the second sensor(s) are configured to detect a position and / or presence of at least one person in a second monitoring area of ​​the cabin as second sensor data.

[0032] The monitoring system includes an evaluation device. The evaluation device is configured to calculate a distance between the persons in the monitored areas based on the first and second sensor data.

[0033] The monitoring arrangement comprises a control device. The control device is designed to control at least one output device based on the calculated distance.

[0034] The monitoring arrangement comprises at least one output device. The at least one output device is designed to output an enable signal or a prohibition signal based on a change in the position and / or presence of at least one person in the monitored areas, depending on the calculated distance.

[0035] An aircraft with the cabin according to the previous description and / or according to one of claims 1 to 6 forms a further subject of the invention.

[0036] A further subject of the invention is a method for monitoring an aircraft cabin, using the monitoring arrangement according to the previous description. The cabin to be monitored is designed according to the previous description and / or according to one of claims 1 to 6.

[0037] Within the scope of the method, an enable signal or a prohibition signal is issued via a change in a position and / or presence of at least one person in a first monitoring area of ​​the cabin and / or in a second monitoring area of ​​the cabin.

[0038] Further features, effects, and advantages of the invention will become apparent from the following description of a preferred embodiment of the invention and the accompanying figures. These show: Figure 1 shows a cabin of an aircraft with a first monitoring area, which is monitored by a first sensor device; Figure 2 shows the cabin with the first monitoring area and with a second and a third monitoring area, which are monitored by a second and a third sensor device; Figure 3 shows a schematic structure of a monitoring arrangement for monitoring monitoring areas of the cabin.

[0039] Identical or identical parts are provided with the same reference numerals in the figures.

[0040] In the Figure 1 A cabin 1 of an aircraft for civil aviation is shown obliquely from above. The cabin 1 is designed as a passenger cabin. It has a seating area 2 with a plurality of seats 3, which are arranged in rows of several seats, e.g. three seats. Passengers 4 of the aircraft can sit on the seats 3. The cabin 1 can comprise one, two or more seating areas 2. Between the seating areas 2 or next to the seating area(s) 2 runs an aisle 5, along which the passengers can walk to get to their seats 3 or from there to a lounge and / or functional area 13 (see Figure 2 ) to reach cabin 1.

[0041] An overhead area 6 with overhead luggage compartments 7 is arranged above the seating area 2. On an underside of the overhead area 6 facing the seats 3, a supply duct 8, or passenger supply channel, extends across the rows of seats. Integrated into the supply duct 8 are, for example, ventilation nozzles and seat belt signs for each row of seats or for each seat 3 in the row.

[0042] Cabin 1 includes a mobile computer 9, e.g., a tablet or laptop. Computer 9 has a display. Alternatively, the computer can also be configured as a stationary computer with a screen. A member of the cabin crew 20 located in cabin 1 uses and / or operates computer 9.

[0043] The cabin 1 has a monitoring arrangement 10 for monitoring monitoring areas 11, 14, 17 of the cabin 1. A schematic structure of the monitoring arrangement 10 is shown in the Figure 3 shown.

[0044] The cabin 1 has a first monitoring area 11. The first monitoring area 11 is formed by and / or encompasses the aisle 5.

[0045] The monitoring arrangement 10 has a first sensor device 12. The first sensor device 12 comprises one or more first sensors, which are arranged on the walls, ceiling, and / or floor of the cabin 1 and can form a sensor network. The first sensor(s) are designed, for example, as optical sensors, e.g., as cameras, optionally as so-called time-of-flight sensors.

[0046] The first sensor device 12 detects a position and / or presence of at least one person, in particular at least one passenger 4 or member of a crew or on-board personnel 20, in the first monitoring area 11 as first sensor data 21. In particular, the first sensor device 12 detects whether and / or how many people are in the aisle 5, whether and / or how many people enter the aisle 5 and whether and / or how many people leave the aisle 5.

[0047] In the Figure 2The cabin 1 is shown in a view of the backs of the seats 3 along the aisle 5. The cabin 1 has the lounge and / or functional area 13. The lounge and / or functional area 13 comprises a lavatory 15 spatially separated from the seating area 2 and a waiting area 19 in front of the lavatory 15. The lounge and / or functional area 13 can optionally additionally comprise an entrance and / or exit area of ​​an aircraft door (not shown).

[0048] The cabin 1 has a second monitoring area 14. The second monitoring area 14 is formed by and / or encompasses the lounge and / or functional area 13.

[0049] The monitoring arrangement 10 has a second sensor device 16. The second sensor device 16 comprises one or more second sensors, which can form a sensor network. The second sensor(s) are designed, for example, as optical sensors, e.g., as cameras, optionally as so-called time-of-flight sensors. The second sensor(s) are arranged on the wall, ceiling, or floor of the lavatory 15. One or more other second sensors can optionally be arranged on the wall, ceiling, or floor in the waiting area 19 and / or in the entrance and / or exit area of ​​the aircraft door. One or more second sensors can also be arranged on an access door to the lavatory 15. These can be designed, for example, as motion sensors and detect door opening and closing movements in order to be able to evaluate whether the lavatory 15 is occupied or not.The second sensor(s) arranged on the access door can also be designed as optical sensors.

[0050] The second sensor device 16 detects a position and / or presence of at least one person in the second monitoring area 14 as second sensor data 22. Thus, the second sensor device 16 detects whether and / or how many people are in the residence and / or functional area 13, whether and / or how many people enter the residence and / or functional area 13, and whether and / or how many people leave it.

[0051] The cabin 1 has at least one further monitoring area, in particular a third monitoring area 17. The third monitoring area 17 is formed by the seating area 2 or by the seating areas 2.

[0052] The monitoring arrangement 10 has at least one further sensor device, in particular a third sensor device 18. The third sensor device 18 comprises a plurality of third sensors that form a sensor network. The third sensor(s) are designed, for example, as optical sensors, e.g., as cameras, optionally as so-called time-of-flight sensors. The third sensors are arranged in the supply duct 8. A third sensor is assigned to each seat 3 of the seating area 2, or alternatively, to each row of seats. The third sensor device 18, in particular the third sensor assigned to the respective seat 3, detects the occupancy of the seat 3 by a person as third sensor data 23.

[0053] The monitoring device 10 has an evaluation device 24 for evaluating the first, second, and third sensor data 21, 22, 23. The evaluation device 24 is designed as a microcontroller. It is integrated into the computer 9. Alternatively, it can be a separate component that is connected and / or connectable to the computer 9, e.g., via radio or a cable.

[0054] Based on the first and second sensor data 21, 22 and optionally additionally based on the third sensor data 21, 22, the evaluation device 24 calculates a distance between persons located in the first and second monitoring areas 11, 14 and optionally additionally in the third monitoring area 17. The evaluation device 24 also evaluates the seat occupancy of the seats 3, in particular, it evaluates whether and on which seats 3 of the seating area 2 a person is sitting and whether and which seat(s) are unoccupied.

[0055] The computer 9 is connected by signal and / or data to an external device, e.g. another computer outside the aircraft, which is used, for example, by ground staff at an airport. The evaluated seat occupancy and, optionally, the calculated distance between the people in the monitoring areas 11, 14, 17 can be transmitted to the additional computer. This allows the ground staff, for example, during a boarding process, to gain an impression of how quickly the passengers in the cabin 1 are getting into their seats 3, which seats 3 are already occupied, how many people are in the aisle 5, waiting area 19 and / or in the entrance and / or exit area of ​​the aircraft door and at what distance. The ground staff can therefore advantageously structure the boarding process in a more regulated manner, in particular by avoiding passenger congestion in the monitoring areas and / or avoiding queues in front of the aircraft door.

[0056] The monitoring device 10 comprises a plurality of output devices 25. The output devices 25 are arranged above each row of seats in the seating area 2 in the supply channel 8. Each of the output devices 25 is assigned to exactly one seat 3 in the row.

[0057] The output devices 25 are designed as traffic lights for outputting two or more differently colored optical signals. A first signal color output by the traffic light, e.g., green, forms an enable signal 26. A second signal color output by the traffic light, e.g., red, forms a prohibition signal 27. Optionally, a third signal color, e.g., orange, can be output, which can form a wait signal until the change between the enable signal 26 and the prohibition signal 27 occurs. It is also possible for the output devices 25 to be designed to output acoustic signals, which can indicate the output and the change between the optical signals.

[0058] The release signal 26 and the prohibition signal 27 are intended to influence the position and / or presence of at least one person in the monitored areas 11, 14, 17. The prohibition signal 27 signals the passenger in the corresponding seat 3 that they must remain seated and are not allowed to leave seat 3. The release signal 26 signals the passenger in the corresponding seat 3 that they may stand up and leave seat 3.

[0059] The monitoring arrangement 10 comprises a control device 28 for controlling the output devices 25 based on the calculated distance between the persons in the monitoring areas 11, 14, 17. The control device 28 is integrated into the computer 9 or is connectable or connected thereto. A control algorithm is stored in the control device 28, by means of which the output devices 25 can be controlled with algorithm-based control signals 29 based on the calculated distance.

[0060] For example, the control algorithm includes limit values ​​for a minimum distance between any two persons in one, several, or all monitoring areas 11, 14, 17. If the limit value is reached or undershot, the control device 28 triggers the output of the prohibition signal 27 for the corresponding seats 3. If the limit value is not reached, the control device triggers the release signal 26 for the corresponding seats 3. According to the control algorithm, the control device 28 can, for example, also take into account the distance between two persons and specific seats 3 and / or rows of seats, so that the control device can accordingly trigger the release signal 26 for specific rows of seats and the prohibition signal 27 for other rows of seats.

[0061] This advantageously avoids a close gathering of people in the first and second monitoring areas 11, 14. This ensures that distancing rules, e.g., to reduce the spread of infection during a pandemic or similar situations, are observed.

[0062] The member of the on-board crew 20 can also control the output devices 25 by issuing manual control commands using the computer 9 and, in particular, the control device 28 integrated therein or connected to it. For this purpose, the calculated distance and / or the evaluated seat occupancy can be shown on the display so that the member of the on-board crew 20 can take note of them. The control commands can be entered via the display as a touchscreen or via a keyboard, etc.

[0063] For example, the member of the cabin crew 20 can influence the disembarkation process of passengers 4 from the aircraft by manually controlling the dispensing devices 25. If the release signal 26 is activated, for example, only for seats 3 in every third row of seats in the seating area 2, it can be achieved in particular that not all passengers 4 crowd into the aisle 5 at the same time to remove their luggage from the overhead storage compartments 7 and move to the aircraft door. The disembarkation process can proceed in an orderly manner and is thus more relaxed and pleasant for the passengers 4 and the cabin crew 20. In addition, close gatherings can be avoided and any necessary distancing rules in the first and second monitoring areas 11, 14 can be observed.

[0064] As from the Figure 3As can be seen, the evaluation device 24 is signal-connected to the first, second, and third sensor devices 12, 16, 18. The sensor devices 12, 16, 18 transmit the acquired first, second, and third sensor data 21, 22, 23 to the evaluation device 24.

[0065] The evaluation device 24 is connected to the control device 28 via signaling. It transmits the calculated distance as distance signals 31 to the control device 28. It can also transmit the calculated distance as distance signals for display on the display of the computer 9. Furthermore, the evaluation device 24 transmits the evaluated seat occupancy as seat occupancy signals 32 to the control device 28 and / or for display on the display of the computer 9.

[0066] The control device 28 is connected to the output devices 25 via radio, in particular Wi-Fi or Bluetooth. For control, the control device 28 sends the algorithm-based control signals 29 or control signals 30 based on the manual control commands to the output devices 24. List of reference symbols
