METHOD FOR PROVIDING PASSENGER ACCESS TO A PASSENGER AREA OF A PASSENGER AREA OF A LANE-BOUND VEHICLE

Description

[0001] The invention relates to a method for providing passenger access to a passenger area of ​​a passenger compartment of a track-bound vehicle.

[0002] It is generally known to restrict access to a specific area of ​​a rail-bound vehicle. For example, rail vehicles are known as traction vehicles, where passenger access to the driver's area (often also called the driver's cab) is restricted by means of a lockable door.

[0003] WO 2017 / 036714 A1 describes a method for activating an access control unit using a mobile electronic device. Starting from a locked state that blocks access to an area, the access control unit is activated to an unlocked state that allows access. Activating the access control unit to the unlocked state requires the existence of access authorization. This authorization is verified against an authorization database.

[0004] DE 10 2012 218 143 A1 describes an operating system for operating functional units in a rail vehicle, wherein at least one base station is provided in each car of the rail vehicle, which communicates via a wireless interface with a mobile device of an authenticated user, in particular an authenticated train attendant, who operates functional units of the rail vehicle via a graphical user interface of the mobile device.

[0005] US 2007 / 0040672 A1 describes a mass transit and mass transportation safety system by which a substantial number of passengers and / or pieces of luggage are transported by an intermodal transportation vehicle, such as a bus, ship, train, subway, or aircraft. The system comprises: a) a vehicle that carries a substantial amount of luggage and / or passengers, containing a plurality of seats for the crew and / or passengers and a luggage hold by which luggage is stored for transit, and which vehicle has at least one seat for a driver, pilot, or operator, and which vehicle has at least one door or entry point by which people and / or luggage enter and exit;b) a first sensor connected to each door opening or other designated detection points within the vehicle, emitting a first signal relating to the identity and presence of any identification medium passing within detectable proximity of the first sensor; c) a second sensor mounted on the vehicle for detection, emitting a second signal indicative of radioactive, explosive, and / or biohazardous material located inside or in close external proximity to the vehicle; d) a third sensor connected to each designated operator and passenger seat for detection, emitting a third signal indicative of a person occupying the corresponding seat;e) a fourth sensor connected to each seatbelt for detection, which is connected to each seat and outputs a fourth signal indicative of a person seated and buckled in the associated seat; f) an alarm triggered in response to a predetermined signal; g) a display located within the line of sight of the vehicle operator or vehicle crew to show collected data and information, in particular correlated with the corresponding occupancy of seats and other conditions relating to the vehicle, and which display consists of one or more selectable screen(s) available to an operator, with manual control of input and screen selection by the operator;h) Devices for indicating and displaying the identification, presence, and location of each piece of luggage or person in the vehicle, depending on the initial signals received, and for comparison with any previously loaded load list in memory to generate an initial differential signal; i) Devices for indicating and displaying all designated seating positions within the vehicle, including information concerning the occupancy status and seatbelt use, according to the third and fourth signals; j) Devices for indicating and displaying any alarm within the system;k) a computer system for controlling the safety system, comprising an input / output for generating an input signal by a driver, operator, or authorized person, a memory and a processor for receiving the signals and initiating an alarm depending on which memory is capable of storing collected and associated data relating to the signals, the status of sensors, and the status of the display, which data includes load directories and trip history downloads; l) three communication modes, comprising i) a dedicated wireless communication network, ii) a conventional cellular wireless protocol, and iii) a satellite transceiver for satellite-based communication outside of modes i) and ii); m) a cellular wireless jamming device (57) that responds to a signal generated by the processor;n) Devices for inputting information into memory via the processor from hardwired and wireless sources; o) enabling the processor to compare the identification of baggage or persons within the vehicle, as received from the first sensor, with relevant data stored in memory, with information such as a passenger or baggage loading list, and to identify expected, authorized, or unauthorized passengers or baggage, and, depending on any discrepancy, to initiate the specified signal to activate the associated alarm, and additionally to enable selection of different communication methods, and, depending on a specified alarm signal initiated by a sensor, to select or deselect a communication mode to a remote location, and additionally to activate the cellular wireless jamming device.;

[0006] DE 10 2014 219 692 A1 describes a method for detecting a hazardous situation in the interior of a vehicle. To achieve automated detection of a hazardous situation in the vehicle interior, it is proposed that a sensor unit generates a sensor signal that depends on a condition prevailing in the vehicle interior. An analysis unit uses this sensor signal and a hazard function to determine a hazardous condition. The analysis unit then generates hazard information based on the determined hazard condition. A vehicle control unit receives this hazard information and, according to an instruction contained in the hazard information, changes the locking state of a vehicle door. For example, a door is locked to prevent a criminal from escaping or unlocked to allow vehicle occupants to leave the vehicle in the event of a fire.

[0007] The invention is based on the objective of increasing the safety for passengers who are in the track-bound vehicle.

[0008] This problem is solved by a method for providing passenger access to a passenger sub-area of ​​a passenger area of ​​a track-bound vehicle according to claim 1.

[0009] The invention is based on the understanding that operators of rail-bound vehicles wish to protect their passengers in the event of a dangerous situation. In particular, it is desirable to protect passengers from persons who pose a danger to the passengers.

[0010] The solution according to the invention solves this problem by restricting access to the passenger area when a dangerous situation arises. Passengers requiring protection can remain in the passenger area or go there to seek protection from persons who are outside the passenger area and pose a danger.

[0011] A significant advantage of the invention lies in the increased safety of passengers using the track-bound vehicle. The resulting sense of security increases passengers' willingness to choose track-bound vehicles as their mode of transport. In particular, it increases the likelihood of using track-bound vehicles at times and / or in locations where their use poses a perceived higher safety risk. Specifically, passengers who are exposed to a higher safety risk due to their language, ethnicity, religion, sexual identity, or social role will be more likely to choose track-bound vehicles as their mode of transport.

[0012] The passenger area is preferably a spatial area within the track-bound vehicle intended for the presence of one or more passengers. For example, all interior areas of the track-bound vehicle that are not exclusively intended for attendant personnel and / or the installation of vehicle components are passenger areas. The passenger area is preferably an interior area of ​​a car or a section of an interior area of ​​a car of the track-bound vehicle.

[0013] The track-bound vehicle is preferably a rail vehicle. More preferably, the track-bound vehicle is a vehicle for passenger transport in local and / or long-distance public transport.

[0014] The access restriction device preferably comprises a door mechanism. When the door mechanism is closed and blocked (locked), it separates the passenger compartment from another area of ​​the track-bound vehicle, preferably in such a way that passenger access to the passenger compartment from the other passenger compartment is not possible. Passenger access to the passenger compartment is preferably provided by an open door mechanism or a door mechanism that can be opened by anyone. The term "restriction" is understood by those skilled in the art to mean that the door mechanism is closed and can no longer be opened by anyone.

[0015] The occurrence of a hazardous situation can be determined and / or ascertained in various ways: For example, it can be determined by a specific time of day. For instance, a hazardous situation is considered to have occurred at a predefined time in the evening of a given day. Thus, the period between evening and the following morning is considered a hazardous situation. Alternatively or additionally, the occurrence of a hazardous situation can be determined by the location of the track-bound vehicle. For example, traveling through a specific section of road, such as in a specific district, is considered a hazardous situation.

[0016] Alternatively or additionally, the occurrence of a dangerous situation is preferably determined on a case-by-case basis. For example, a physical attack on a passenger by a person posing a danger is considered a dangerous situation.

[0017] The method according to the invention comprises: restricting passenger access depending on the access authorization of a person located in the vehicle. The person is preferably a person who requests access to the passenger area. Those skilled in the art understand the term "access authorization" preferably to mean that, while a hazardous situation exists, access to the passenger area is provided exclusively to authorized persons. An authorized person is preferably an accompanying person (e.g., the driver, crew, and / or station staff) who accompanies the vehicle, and / or a security person appointed by the operator to resolve the hazardous situation. Alternatively or additionally, an authorized person is preferably an authorized passenger who is designated for access to the passenger area while a hazardous situation exists.Eligible passengers are preferably passengers who belong to a predetermined group of people, for example, female persons.

[0018] According to the invention, access authorization is determined based on booking information that represents a booking of passenger access and / or a reservation of a seat or standing place within the passenger area for the person. In this embodiment, the person is preferably a passenger. The booking of passenger access for the person preferably results from the reservation. More preferably, the booking is made as part of the ticket purchase. For example, the operator provides a reservation system that allows a user to reserve a seat within the passenger area for the passenger. Once the seat is reserved for the passenger, the passenger is considered authorized to access the passenger area, particularly during a hazardous situation.

[0019] This has the advantage of increasing the feeling of safety and thus the tendency to choose rail-bound vehicles as a means of transport: because even before the journey begins, it can be ensured by booking that a seat within the passenger area (with restricted access in the event of a dangerous situation) and access to the passenger area are provided for the passenger.

[0020] The operator's reservation system preferably provides authorized users with information about the location of the authorized passenger within the passenger area. An authorized user could be, for example, a parent or legal guardian of a minor passenger or a guardian of a passenger who lacks legal capacity.

[0021] Furthermore, the passenger area is preferably monitored by a camera system when a hazardous situation occurs (and while the hazardous situation persists). The images generated by the camera system can be made available to the operator and / or a security person appointed by the operator to resolve the hazardous situation. In this way, safety within the passenger area is further increased.

[0022] Individuals who are unauthorized to be in the passenger area (for example, because they entered the passenger area together with an authorized person) can be detected by the camera system and identified – for example, using facial recognition. Furthermore, other hazards arising within the passenger area can be identified.

[0023] Finally, measures can be taken to address a hazard posed by an unauthorized person: For example, a security guard will make an announcement to warn other passengers and / or directly address the unauthorized person. The unauthorized person will also be tracked, for example, using the camera system. Images of the unauthorized person will be continuously transmitted to the security guard (for example, via a device they carry). Alternatively or additionally, the unauthorized person can be identified, for example, by controlling a lighting system. Tracking and identifying the unauthorized person primarily assists the security guard in locating them.

[0024] The passenger can give their consent to the monitoring of the passenger area, for example, when purchasing a ticket and / or reserving a seat.

[0025] The occurrence of a hazardous situation can be determined, for example, based on image information captured by a camera system. The method according to the invention comprises: determining the occurrence of the hazardous situation at least on the basis of the activation of a warning device and the generation of warning information, which at least represents the occurrence of the hazardous situation, upon activation.

[0026] The activation of the alarm device is preferably carried out by a passenger.

[0027] The signaling device can be designed as an actuating element, the activation of which directly triggers a restriction of personal access. For example, the actuating element can be designed as an emergency button, the activation of which leads to a blocking of a door mechanism.

[0028] The alarm device can alternatively be designed as an actuating element, the activation of which indirectly triggers a restriction of personnel access. For example, the alarm information can be evaluated by an entity that is mechanically and / or spatially separate from the alarm device with regard to the occurrence of the hazardous situation. This entity is preferably a data processing unit of the vehicle.

[0029] The alarm device can alternatively or additionally be designed as a permanently installed emergency call device within the track-bound vehicle. The alarm device is preferably designed to record a voice message from the passenger and generate audio information based on the recording. The recording preferably includes verbal information about the hazardous situation.

[0030] In a preferred training scenario, the reporting device includes a mobile device carried by a vehicle attendant and / or a passenger. Using a mobile device as a reporting device is particularly practical, as passengers frequently carry one. The ability to activate the mobile device to report a hazardous situation is preferably provided by an application loaded onto the mobile device. This application is preferably provided by the operator.

[0031] The mobile device is preferably connected to the vehicle's communication network, such as an operator network, via a wireless connection, for example, a WLAN connection (WLAN: Wireless Local Area Network). The mobile device then transmits the notification information, preferably via this connection, to a data processing unit that is also connected to the vehicle's communication network.

[0032] The mobile device is preferably designed as a smartphone, wearable (e.g. smartwatch) and / or tablet.

[0033] According to the invention, access for individuals is restricted based on the reporting information.

[0034] Preferably, a data processing unit connected to the vehicle's communication network triggers the restriction of personal access upon receipt of the alarm information. This triggering preferably occurs when the data processing unit sends a control signal to the access restriction device. The control signal can be transmitted as a data packet via the vehicle's communication network to the door control unit. For example, the data processing unit sends a blocking signal to a door control unit of the door control unit, whereby the blocking signal causes the door control unit to be blocked.

[0035] A preferred further training includes: sending the notification information to a land-based data processing facility and triggering the restriction by means of the data processing facility based on the received notification information.

[0036] Preferably, the notification information is sent from the notification device to a vehicle-side data processing unit connected to the communication network and transmitted from the vehicle-side data processing unit to a land-side data processing unit via a wireless data connection.

[0037] In addition to the notification information, location information, which serves to locate the notification device, is preferably transmitted to the land-based data processing facility.

[0038] In addition to the message information, preferably image information representing a spatial area inside or outside the vehicle captured by a camera system is also transmitted to the land-based data processing facility.

[0039] The land-based data processing unit can use the notification information, the determined location of the notification unit, and / or image information to determine in which area of ​​the passenger compartment a restricted passenger section should be created. Furthermore, the land-based data processing unit can use one or more of the aforementioned pieces of information to determine the extent to which passenger access should be restricted. For example, the data processing unit can determine whether passenger access should be completely blocked and / or whether access should be granted to authorized persons.

[0040] The land-based data processing unit preferably triggers the restriction of personal access by sending a control signal, which is transmitted as a data packet to the vehicle-based data processing unit. The activation then preferably occurs when the vehicle-based data processing unit sends the control signal to the access restriction device.

[0041] Alternatively or additionally, the land-based data processing unit transmits the alarm information, location information, and / or image information to a security officer via a land-based terminal. Using an actuator on the land-based terminal, the security officer preferably triggers the restriction of passenger access. The security officer can preferably decide which passenger area should be subject to access restrictions and trigger the restriction accordingly via the land-based terminal. For example, the security officer can use the alarm information, the determined location of the alarm unit, and / or the image information to determine in which area of ​​the passenger area access restrictions should be established.Furthermore, the security officer can use one or more of the aforementioned pieces of information to determine the extent to which access to persons should be restricted.

[0042] In the method according to the invention, restricting personal access includes a Determining the person's access authorization using a verification device and granting access to the person using an access restriction device depending on the result of determining the access authorization.

[0043] Preferably, personal access is granted to the person if the result of determining access authorization is: Access authorization exists.

[0044] For preferred further training, eligibility for access is determined using identification information, which from a mobile device and / or an identification element, that is carried by the person and provided.

[0045] If the identification information is provided by the mobile device, it is preferably transmitted to the testing facility via a wireless data connection, for example a WLAN connection (Wireless Local Area Network), Bluetooth connection and / or near field communication connection (NFC).

[0046] The identification element is preferably designed as a card with an RFID element (RFID: Radio Frequency Identification), wherein the identification information can be read from the RFID element by means of the testing device.

[0047] In the case of preferred further training, determining eligibility for access includes a Capturing a biometric characteristic of the person using a capture device and determining access authorization based on the biometric characteristic.

[0048] Capturing the biometric feature preferably involves capturing the person's face using a camera unit. The camera unit preferably generates image information representing the person's face. This image information is then evaluated using the testing device.

[0049] The recording of the biometric characteristic preferably further includes (alternatively or additionally) the recording of a fingerprint of the person.

[0050] According to a further preferred embodiment, the access restriction device comprises at least one inner door that separates the passenger compartment from another area of ​​the track-bound vehicle. Releasing access includes opening the inner door. The other area is preferably a part of the passenger compartment that lies outside the passenger compartment.

[0051] According to a preferred training method, the interior door includes a Compartment door, which separates a passenger area inside a compartment from a passenger area outside the compartment, and / or a carriage transition door, which separates a passenger area inside a first carriage from a passenger area inside a second carriage.

[0052] In other words, the passenger compartment is a passenger area within a compartment and / or a passenger area within a first carriage.

[0053] Designing the interior door as a compartment door has the advantage that a compartment can be restricted with regard to passenger access by means of a single door.

[0054] Designing the inner door as a carriage transition door has the advantage that, by means of two carriage transition doors, each located at the end of the carriage, passenger access to a carriage can be restricted (if all outer doors of the carriage are blocked).

[0055] According to a preferred embodiment of the method according to the invention, the access restriction device comprises at least one outer door which separates the passenger compartment from a spatial area in the vicinity of the vehicle. The outer door is preferably blocked when a dangerous situation occurs.

[0056] Preferably, the access restriction device comprises a set of doors, including both interior and exterior doors. The doors of the set are arranged such that the passenger compartment is inaccessible to any person when all doors are blocked. In particular, the set includes all doors through which passenger access to the passenger compartment is possible. For example, if the passenger compartment consists of a carriage, the access restriction device includes all exterior doors that provide access to the carriage, as well as any gangway doors located at each end of the carriage.

[0057] The invention further relates to an access restriction device for providing passenger access to a passenger area of ​​a track-bound vehicle, which is designed to restrict passenger access to the passenger area in the event of a dangerous situation.

[0058] The access restriction device includes at least one interior door that separates the passenger area from another area of ​​the track-bound vehicle.

[0059] The access restriction device includes at least one external door that separates the passenger area from a spatial area in the vicinity of the vehicle.

[0060] The access restriction device preferably includes a verification device for determining a person's access authorization.

[0061] The invention further relates to a track-bound vehicle comprising: a passenger compartment and an access restriction device of the type described above.

[0062] The track-bound vehicle preferably includes a reporting device which is designed to be activated to generate and send a reporting information.

[0063] The track-bound vehicle further preferably comprises a vehicle-side data processing device which is designed to receive the message information and send it to a land-side data processing device.

[0064] The vehicle-side data processing equipment is preferably designed to trigger the restriction of personal access.

[0065] For details on the design, features and advantages of the access restriction device and the track-bound vehicle, please refer to the description of the corresponding process characteristics.

[0066] Exemplary embodiments of the invention will now be explained with reference to the drawings. The drawings show: Figure 1 shows a schematic flowchart of a method according to the invention in an embodiment, Figure 2 shows a schematic diagram of the structure of a track-bound vehicle with an access restriction device in a first embodiment, and Figure 3 shows a schematic diagram of the structure of a track-bound vehicle with an access restriction device in a second embodiment.

[0067] Figure 1 Figure 1 shows a track-bound vehicle 1 in the form of a rail vehicle 2 in a partial schematic sectional view as a top view. Figure 2schematically shows the sequence of an exemplary embodiment of a method according to the invention.

[0068] The rail vehicle 2 is designed as a train consisting of several cars 4, 6, which are mechanically coupled to each other and form a train unit. In the embodiment under consideration, the rail vehicle 2 is designed as a so-called multiple unit train.

[0069] The track-bound vehicle 1 has a passenger area 12, which comprises a first passenger section 14 and a second passenger section 15. The track-bound vehicle 1 has an access control device 5, which includes external doors 32, 33, 34, 35 and an internal door 38. The second passenger section 15 is separated from a spatial area 36 in the vicinity of the vehicle 1 by the external doors 32, 33, 34, 35. Furthermore, the passenger section 15 is separated from the passenger section 14 by the internal door 38.

[0070] In normal operation, the outer doors 32, 33, 34, 35 and the inner door 38 provide passenger access to passenger area 15 (procedure step A). ​​The outer doors are closed while the train is in motion and are temporarily opened when the train stops at a station to allow passengers to board and alight.

[0071] If a hazardous situation arises during the operation of vehicle 1, a passenger 16 may perceive it. Passenger 16 then activates a reporting device 18 in a procedure step B. The reporting device 18 is a mobile terminal 19 carried by passenger 16. For example, the option for passenger 16 to activate the device is provided by an application loaded on the mobile terminal 18. The application may also provide a query through which passenger 16 indicates the area of ​​vehicle 1 where the hazardous situation exists.

[0072] Alternatively, passenger 16 can activate a permanently installed alarm device 20 in vehicle 1, which is designed as an emergency call device 21.

[0073] Upon activation of B, the reporting device 18 or 20 generates a reporting information in a process step C, which represents the occurrence of the hazardous situation and, if applicable, indicates the area of ​​the vehicle 1 in which the hazardous situation exists.

[0074] The reporting device 18 or 20 sends the reporting information via a wireless data connection to a data processing device 22 of the vehicle 1.

[0075] The data processing unit 22 is connected to a land-based data processing unit 24. In process step D, the data processing unit 22 sends the alarm information to the land-based data processing unit 24. In addition to the alarm information, image information, generated by a camera system and representing at least a portion of the passenger area 12, is sent to the land-based data processing unit 24 in process step DD.

[0076] The data sent in process steps D and DD from vehicle 1 to the land side is transmitted via a wireless data connection 40.

[0077] The land-based data processing unit 24 is part of a security control center 26. The security control center 26 includes a display device 27 for outputting the alarm information and image information to a security person 29.

[0078] By means of an operating device 28, the security person 29 can trigger, in a procedure step E, that passenger access to the passenger area 15 is restricted. For example, the security person 29 can trigger the restriction of passenger access by selecting the outer doors 32, 33, 34, 35 and the inner door 38 for blocking via the operating device 28.

[0079] Alternatively, the data processing unit 24 can use location information to determine the location of the reporting unit 18 or 20 and, in a procedure step EE, trigger a restriction of personal access to the passenger area 15.

[0080] In a process step F, control information is transmitted to the data processing unit 22, which causes a restriction of person access in a process step G by restricting the access for persons to the passenger area 15 through the outer doors 32, 33, 34, 35 and the inner door 38.

[0081] In particular, access by persons outside vehicle 1 via the exterior doors 32, 33, 34, 35 is blocked, regardless of access authorization. Access by persons located within passenger compartment 14 is restricted: A person 42 requesting access to passenger compartment 15 via the interior door 38 will be granted this access only after an authorization check. For this purpose, in process step H, an access authorization for person 42 is determined by means of a verification device 23.

[0082] To determine access authorization H, identification information is provided in process step J by a mobile device 46 carried by person 42 and received by an access unit 44 of vehicle 1 in process step K. The identification information is transmitted, for example, via near-field communication (NFC). Alternatively, the identification information can also be transmitted via WLAN (Wireless Local Area Network) or Bluetooth.

[0083] To determine H the access authorization, in an additional procedure step L the face of person 42 is recorded as a biometric feature by means of a recording device 48, which is designed as a camera unit 49.

[0084] The identification information and facial information representing the captured face are sent to the verification unit 23 via the communication network. In process step M, the verification unit 23 checks whether person 42 should be granted access to passenger area 15 based on the provided identification information and facial information. In addition to the identification information and facial information, verification M can also be performed using booking information resulting from a seat reservation for person 42 within passenger area 15. If verification M is successful, access to passenger area 15 is granted in process step N by unlocking the inner door 38 using the access unit 44.

[0085] Figure 3Figure 101 shows a track-bound vehicle 101 in the form of a rail vehicle 102 in a partial schematic sectional view as a top view. Vehicle 101 is similar to the one described in relation to... Figure 1 The vehicle 1 described above is constructed and can be operated essentially according to the method described with reference to Figure 1. Identical and functionally equivalent elements are provided with the same reference numerals.

[0086] The track-bound vehicle 101 has a passenger area 12, which comprises a first passenger section 114 and a second passenger section 115. The track-bound vehicle 101 has an access control device 105, which includes external doors 132, 133, 134, 135, 139, 141 and an internal door 138. The second passenger section 115 is separated from a spatial area 36 in the vicinity of the vehicle 101 by means of the external doors 132, 133, 134, 135, 139, 141. In addition, the passenger section 115 is separated from the passenger section 114 by means of the gangway door 138.
