Definitions
- the present invention relates to a door system for a public transport vehicle having at least one door opening and a door closing the door opening. Furthermore, the application relates to a method for monitoring and controlling such a door system.
- Door systems are used in particular in rail and road vehicles, but also on boats and in aircraft. Door systems of this kind are monitored in many respects and controlled according to a wide variety of conditions. On the one hand, the safety of incoming and outgoing passengers must always be guaranteed, on the other hand, doors or door leaves should open and close reliably and only under certain conditions. It must also be prevented that people or objects between two door leaves or a door leaf and a door frame are trapped.
- door systems in the context of the invention also includes boarding aids, such as sliding steps or treads. Their function and use must also be monitored and controlled, as there are, for example, obstacles on them that pose a danger to the passengers. It must also be ensured that no persons or objects are trapped between the boarding aid and the platform and the boarding aid does not hit against persons.
- boarding aids such as sliding steps or treads. Their function and use must also be monitored and controlled, as there are, for example, obstacles on them that pose a danger to the passengers. It must also be ensured that no persons or objects are trapped between the boarding aid and the platform and the boarding aid does not hit against persons.
- Tread sensors safety mats, strain gauges or the like for detecting loads on treadle system and boarding aids.
- the object of the invention is, on the one hand, to provide a door system in which the above-mentioned monitoring and control tasks can be achieved with the least possible outlay.
- the installation, maintenance and repair should be easy and low cost possible. In particular, the number of required components should be reduced.
- the door system should be suitable for optimizing boarding and boarding procedures and avert risks for passengers at an early stage.
- the object of the invention to provide a corresponding method for monitoring and control of such a door system.
- a door system comprises a sensor unit which scans a passenger compartment three-dimensionally in the area of the door opening and at least one communication element for context-based communication with passengers on the basis of measurement results of the sensor unit.
- the method according to the invention comprises the following method steps: Contactless three-dimensional scanning of a passenger compartment in the region of a door opening (44) with a sensor unit (26),
- the passenger or boarding room is therefore detected or scanned three-dimensionally with the aid of a sensor unit inside and / or outside the vehicle.
- This three-dimensional scanning can be done on the basis of known optical systems such as infrared sensors, infrared laser scanners or suitable camera systems with optical image data evaluation, also conceivable is a scan with ultrasound.
- optical systems such as infrared sensors, infrared laser scanners or suitable camera systems with optical image data evaluation, also conceivable is a scan with ultrasound.
- tests for possible collisions of the door and door systems with the surroundings or passengers can be carried out.
- previously defined points in the room can be used as virtual buttons for controlling the door and door systems.
- An essential aspect of the invention is therefore that the context-based information is output according to the invention directly to the affected user. Information is therefore output where it is needed, for example at a specific door to a specific passenger. This avoids that the passenger concerned does not feel addressed due to a generally formulated information that is output at all doors.
- context-based communication is advantageous if specific hazard potential has been detected by the sensors. If, for example, snow is on a sliding step or if there is a gap between the sliding step and the platform, exactly those passengers in the area of the corresponding door who are affected by the danger are informed according to the invention.
- the communication may take the form of an announcement or an indication on a display on the corresponding door. In this case, the communication by the driver himself, who was previously made aware of the danger by the system, can However, according to an automated announcement or display in the area of the corresponding door is possible.
- the sensor unit determines a specific relevant state or corresponding data, forwards them to a computer unit, which then outputs context-based, locally relevant information.
- Context-based information means that this is not output automatically and globally everywhere, but that it is based on the data determined by the sensor unit and is adapted specifically to the conditions on site
- the context determines which passenger or passengers are affected, whom the information should reach, and the latter in turn, on which door or doors the information is relevant
- the invention will be described essentially by way of example for the use of the laser scanner unit, but instead of the laser scanner unit, the abovementioned alternatives can also be described Sensor units are used.
- the term laser scanner unit is then to be understood as a synonym for all suitable sensors.
- the sensor unit is formed by a laser scanner unit, which is arranged in the region of the door opening.
- the laser scanner unit generates a kind of point cloud, via which a scanning of the passenger compartment takes place in all three dimensions, ie in the x-direction, y-direction and z-direction.
- the laser scanner unit uses infrared light that is not visible to the human eye.
- a distance measurement is carried out, which is based on the so-called time-of-flight (ToF) principle. This means that the laser scanner emits light pulses and the delay until the measures the reflection of the corresponding light pulse. About the measured delay of the reflection can be concluded that the distance of the scanned point to the sensor unit.
- the distance measurement or monitoring of the passenger compartment is the more accurate, the more samples per unit time.
- the sensor unit includes an evaluation unit with a computer / processor and a suitable software.
- the evaluation unit can alternatively also be arranged externally of the sensor unit, for example in the case of a train in the driver's compartment.
- the arrangement of the sensor unit should be such that the passenger compartment can be optimally scanned, so protrude no unwanted elements in the beam paths. Although these can be ignored by the sensor unit, they cast a shadow.
- the central position above the two door wings that is to say in the region of the abutting main closing edges, has proven particularly advantageous on the outside of the vehicle. The point cloud is emitted downwards from this upper position.
- the mounting of the sensor unit in the middle above the door is particularly favorable, because then the passenger compartment can be optimally scanned.
- an arrangement laterally next to and above the door has proved to be particularly favorable, because in the central arrangement, the support arms of the door would limit the view of the laser scanner.
- an area can be defined in which, for example, a hand movement of a passenger can be evaluated as pressing a button.
- the sensor unit recognizes it and triggers an opening or closing signal for the doors.
- calibrating such a virtual button an object is held in the point cloud at the desired location where the virtual button is to be created. If this is held long enough and it is only this one object for the laser scanner recognizable, the center of the object is determined, whose position is then used as the center of the virtual button.
- a radius around this center is defined, whereby the size of the virtual button can be determined. If this virtual button is activated, the distance of all scanned objects that are detected within the passenger compartment is determined to be the center point of the virtual button. If the distance of an object, for example a passenger's hand, to the center of the virtual button is smaller than the previously determined radius, then the virtual button is considered activated.
- the region of the point cloud which is closest to the door opening is used in particular for detection and activation. This ensures that only movements are considered that come close to very close to the door or vehicle wall. Ideally, passengers must touch the sticker or marker to activate the button.
- buttons can be positioned and set up at any point. No additional cabling is required and changes can be made to the vehicle or position at any time. It is still easily possible and associated with only insignificant additional costs to provide multiple buttons in a door system. It is conceivable, for example, the additional establishment of buttons for children or wheelchair users.
- the entire environment visible to the laser unit or the laser scanner is scanned and stored taking into account tolerances.
- the door portal dimension is integrated into the calibration to hide relevant objects beyond the door. Calibration makes it possible to adapt to different environments, such as platform heights or obstacles.
- the sensor unit easily detects additional objects or elements within the monitored passenger compartment.
- the sensor unit is coupled to the control of the door or door and is able to read each of the current door or door leaf position. The information is used to monitor the space between the leaves, the wider environment can be ignored for this application. With only one door, the area immediately within the door frame or the gap between the main closing edge and the door frame is monitored.
- the sensor unit uses the measurement results not only for the control of the doors, but the measurement results can also be used according to the invention for direct communication with the passengers. For example, passengers may be asked to change their position, to visit another car or other vehicle, or to remove items from hazardous areas. Corresponding instructions or information to the passengers can be automatically output by the door system itself, but they can also be issued by an operator. the driver of the vehicle or an external control center. In the first case, an auxiliary information is automatically generated when certain measurement results are available. If, for example, a person is in the closing or opening area of a door or door leaf, according to the invention it is automatically possible to provide information, for example in the form of an announcement via a loudspeaker, via which the person is asked to leave the danger area.
- Particularly suitable as communication elements are loudspeakers, monitors or illuminants. It can be provided only a single communication element, but alternatively, different or more same communication means can be used. In a particularly simple variant, for example, a light source via the colors red and green signal whether a door will be opened or not. For more information, speakers or monitors are more suitable.
- the communication elements are preferably arranged directly in the region of the door opening.
- the virtual pushbutton can be obscured by larger objects, especially at busy stations, and therefore can not be used.
- the sensor unit takes this case into consideration and, according to the invention, a warning is output via the communication element. This warning can be made to the passenger directly concerned at the corresponding door, for example via speakers, or first to the train or vehicle driver, who then passes this information to the passenger if necessary.
- a signal is generated which z. B. can be used to stop or reversing the door or door.
- a signal is generated which z. B. can be used to stop or reversing the door or door.
- a signal before opening the door can be used to issue a warning to the passengers.
- the signal can only inform those passengers who are also affected. For example, a loudspeaker announcement can be made on the door that stopped or reversed. There are no announcements or instructions at the other doors.
- the door system and method according to the invention can also be used to detect extremities and their position and speed. By using one or more point clouds, a movement speed in the direction of the door opening or away from the door opening can be determined. From these data can be drawn directly conclusions on the intent of a passenger, such as an opening or access request.
- even movement flows of passengers in the area of the doors can be determined and used.
- a door By detecting the direction of movement of a passenger, a door can be locked or opened so as to direct the flow of movement of the passengers in one direction. If, for example, a passenger has passed the door in the permitted direction of movement and no other passenger follows, the door can be closed directly in order to make it difficult for the door to pass in the opposite, wrong direction. If a passenger moves in the wrong direction toward the door, if no one is in the area of the moving door or wants to get off, it can be closed faster if needed, and advantageously depending on the distance and speed of the passenger to prevent in the wrong direction.
- a space in front of the door opening is advantageously monitored, which can extend for example up to 10 m, preferably 2 to 5 m, starting from the door in the direction of the platform or the road.
- Passengers are thus recognized early and it can be timely responded. It is possible to inform passengers who are in the entry area of this door just before closing individual doors that it will close. This information is output only on those doors in front of which passengers are located.
- the scanning of the passenger compartment makes it possible to provide the passenger with context-based information or to him before potential danger situations to warn. For example, if a passenger is leaning against the door or door leaf from inside while opening it, that passenger may be warned beforehand. The same applies to a disturbing object that is leaning against the door. The door can remain locked for opening until the potential danger is removed.
- specific information can be sent to the passengers in the area of this door or object.
- a passenger hides a virtual push button. In this case, it can be stopped via the speaker or monitor or alternative signals to change its position so that the button is reusable. This information is also addressed only to this passenger, on the other doors is no indication.
- a significant advantage for the applications mentioned in particular is that a passenger must not have contact with a moving door to interrupt the opening or closing process and / or initiate a reversing door.
- conventional sensors which are arranged in the main closing edge, the main closing edge must be touched by the passenger, if necessary even pressed in, so that a signal is generated.
- Such a touch is often perceived as unpleasant and can in particular also pollute the clothing of the passenger. Due to the non-contact scanning of the relevant passenger compartment according to the invention, these disadvantages can be effectively avoided.
- the embodiment of the door system according to the invention and the method according to the invention for monitoring the passenger compartment allow further advantageous monitoring and control options. For example, if a door is marked as "defective" and a passenger approaches such a door, he can on the Status of the door via the communication means, such as the speaker to be pointed. This is advantageous because passengers are known to often overlook defects in the form of stickers or notice them only when the door does not work. Also, the driving operation can be accelerated and facilitated by the fact that passengers who prevent the closing of a door by being too close to this door are already asked to step back before closing the door. In sensor systems according to the prior art, the passengers are only then asked by the driver of the vehicle when it detects a malfunction of the door, so if this can not be closed, for example. Such a failure can be saved by prior recognition of the position of the passengers.
- the passenger can be informed about the result via the means of communication and, for example, receive an indication as to which entry he can alternatively choose. Furthermore, it is possible to inform passengers about the degree of filling, in particular about seat occupancy of a particular car and tell them about the communication elements in which car still free seats are available. In principle, it is possible with the aid of the door system according to the invention and the method according to the invention to inform the driver of the vehicle about the movement and use of doors in order to be able to control them optimally.
- unused doors can be closed earlier or automatic doors are released, in front of which passengers are waiting to get off. Closing doors as quickly as possible is particularly advantageous in the case of air-conditioned or heated cars.
- the control of passengers for example on a platform or at a stop in the prior art only on the rear view mirror of the driver and is therefore dependent on its concentration and attention.
- the use of the three-dimensional scanning on the outside of the vehicle can be used according to the invention to detect a snow cover, for example, on a kick and report. Passengers can be made aware of the imminent danger via the communication elements.
- the distance of the door opening to a platform it is also possible to determine the distance of the door opening to a platform, so as to optimally extend the tread or boarding aid. This is particularly advantageous if the distances between see the door opening and the platform differ from station to station. It is thus possible to dispense with corresponding sensors on the approach aids themselves. If, for example, a gap remains between the boarding aid and the platform despite the fully extended sliding step, the passengers can be informed of this directly by the communication elements. This information can also be automatically output by the system itself if appropriate measurement results are available.
- Fig. 1 An inventive door system from the outside in simplified
- Schematic diagram, 2 shows an inventive door system from the inside in a simplified schematic representation
- FIG. 3 is a schematic diagram of the function of a virtual button
- Fig. 4 a schematic diagram for obstacle monitoring between two door leaves.
- Figures 1 and 2 show in a very simplified schematic representation of a door system 20 for a vehicle 42 (see Figure 5) of public passenger transport. This has a not visible in Figures 1 and 2 door opening 44, which is closed in the embodiment shown by a door, formed of two door leaves 22. Below the door a boarding aid 24 is arranged to facilitate the entry and exit from the vehicle 42.
- This approach aid 24 may be formed, for example, as an extendable tread or tread plate.
- Both figures further show a sensor unit 26.
- This is arranged centrally on the outside of the vehicle 42 above the door leaf 22.
- the sensor unit 26 is positioned laterally above the two door leaves 22, since otherwise not shown support arms would possibly limit the view of the sensor unit 26.
- the sensor unit 26 can be arranged at any suitable position, depending on the type of sensor.
- the sensor unit 26 generates a point cloud within the passenger compartment to be monitored, via which the passenger compartment is scanned.
- the sensor unit 26 can have, for example, an optical sensor, preferably a laser, in particular an infrared laser.
- the sensor unit 26 furthermore has an evaluation unit (not shown) for evaluating the measured data.
- This can be integrated into the sensor unit or arranged externally.
- FIGS. 1 and 2 show symbolically different variants of communication means, namely a loudspeaker 50, a monitor 52 and a lighting means 54, all of which are arranged in the region of the door opening 44.
- FIG. 3 illustrates the use of the door system 20 according to the invention for creating a virtual pushbutton 36.
- a virtual pushbutton 36 simulates an otherwise wired, real pushbutton.
- a sticker or a corresponding symbol painting can be provided in the door area.
- an object is held in the desired position of the virtual pushbutton 36 in the point cloud. If this is kept quiet enough long enough, its position can be used as the center 38 for the virtual button 36.
- a radius 40 is determined and stored in the associated evaluation software. If, for example, a passenger's hand now approaches the virtual button 36 within the defined radius 40 through the point cloud, this movement is interpreted as the passenger's request to trigger. As an alternative to the hand of the passenger, any object in this area is correspondingly recognized and considered.
- FIG. 4 illustrates another example of the use of the door system 20 according to the invention.
- An indicated vehicle 42 with a door opening 44 can be seen.
- Two door leaves 22 are in front of it in a slightly open position.
- a first point cloud area PI monitors and is limited to a space between the two door wings 22, it ignores the wider environment.
- a second point cloud area P2 scans the space immediately in front of the two door wings 22 and is stretched slightly further so that it overlaps with the door wings 22 in the expansion. If there is an obstacle in the monitored or scanned rooms, this is reliably detected and closing or moving the door can be interrupted, if necessary, the door is reversed automatically.
- the point cloud area PI thus monitors a space between main closing edges 46 of the two door wings 22.
- the space between the main closing edge 46 of the single door and the door frame is monitored.
- the invention is not limited to the embodiments described and shown, but also other uses of the door system 20 according to the invention are possible.
- an optical imaging monitoring can also take place, with a corresponding evaluation software evaluating movements, shapes and speeds.
- a video camera with a corresponding evaluation program.
- the communication with the passengers can not only be done via loudspeakers, but also via monitors or other optical signals, such as warning lights.
- door openings 44 passages or windows can also be monitored by means of the described method.
- the invention is also suitable in conjunction with other sensor elements, for example ultrasound sensors.
- the sensor unit 26 can be embodied and aligned such that not only the passenger compartment is monitored directly in the area of the door opening, but, for example, a significantly larger space is included in the monitoring on the outside of the vehicle 42. This makes it possible to identify human streams and their direction early and respond to them by opening or closing the door.
- the monitoring of the passenger compartment can only take place outside, only inside and preferably on both sides of the door.
- the sensor unit 26 or the associated evaluation unit is connected to an external display device. This may be provided, for example, by the driver or in a control center, preferably in the station or in the vicinity of a stop. The results of the scanning by the sensor unit 26 can then be evaluated there and further processed.
