Definitions

  • the present invention concerns a system and a method for checking the integrity or completeness of a multi-unit vehicle, said vehicle being preferentially a guided vehicle.
  • the present invention is related to vehicles comprising multiple units (or cars/coaches) and for which the integrity or completeness has to be ensured, notably for security reasons.
  • the present invention concerns all kinds of vehicles comprising multiple units or cars, but is preferentially directed to multiple unit guided vehicles, wherein "guided vehicle” refers to public transport means such as buses, trolleybuses, streetcars, subways, trains or train subunits, etc., as well as load transporting means such as, for example, freight trains, for which safety is a very important factor and which are guided along a route or railway by at least one rail, in particular by two rails.
  • Multi-unit vehicle integrity like train integrity, ensures that the multi-unit vehicle is complete at any time, i.e. that the back of the multi-unit vehicle (train) has not become separated from the front and that the multi-unit vehicle integrity is preserved.
  • train integrity is ensured by wayside devices like track circuits, axle counter, or similar systems, and/or by onboard devices like double coupling which provides two couplings on every vehicle unit, or tail lamp with positioning capability which refers to a device installed at the rear of the train that communicates information (e.g. position of the rear of the train, its speed or its distance from the front of the train) related to train integrity to either the front of the train or the ground, e.g. a wayside device, or alarmed coupling wherein a physical link between two vehicle units provides an alarm if the link is broken, or train circuit wherein a wired link through all vehicles in the train for which any break in the link can be detected.
  • wayside devices like track circuits, axle counter, or similar systems
  • onboard devices like double coupling which provides two couplings on every vehicle unit, or tail lamp with positioning capability which refers to a device installed at the rear of the train that communicates information (e.g. position of the rear of the train, its speed or its distance from the front of the train
  • An objective of the present invention is therefore to propose a system and a method for ensuring completeness of a multi-unit vehicle that is cheap, easy to implement/install/reconfigure on any multi-unit vehicles and that uses little or no power.
  • the present invention proposes to use Radio-Frequency Identification (RFID) techniques and system for checking that a multi-unit vehicle, i.e. a vehicle comprising multiple units, e.g. N units, is complete or not.
  • RFID Radio-Frequency Identification
  • the method according to the invention comprises:
  • the integrity controller may control the integrity or completeness of the multi-unit vehicle by comparing the information related to the presence or absence of the vehicle units that he got through each message M k he received with an initial information related to the initial configuration of the multi-unit vehicle.
  • the initial information might be entered by an operator in a system of the multi-unit vehicle and stored in on-board storing means of the multi-unit vehicle and then read by the integrity controller connected to the multi-unit vehicle system, or might be stored by said operator directly in a memory of the integrity controller.
  • the integrity controller is able to automatically determine the initial configuration of the multi-unit vehicle at a start of a mission by interacting with at least one RFID reader R k in order to get said information comprised in each message M k he receives and then to store in its memory said initial information related to the initial configuration of the multi-unit vehicle. Then, during the mission of the multi-unit vehicle, said integrity controller preferentially communicates with at least one of the RFID readers in order to receive said message M k and controls if the information related to the presence or absence of a vehicle unit diverges from the initial information related to the initial configuration. In particular, in case of divergence, the multi-unit vehicle is able to send an alarm signal to the multi-unit vehicle system.
  • each RFID reader stores in a memory, e.g. in own storing means, an information related to the absence or presence of at least one directly adjacent vehicle unit and then, during mission of the multi-unit vehicle, sends said message M k to the integrity controller if and only if the RFID reader identifies a change in said information related to the absence or presence of at least one directly adjacent vehicle unit.
  • the reception of the message M k by the integrity controller may directly lead to a generation of an alarm signal by said integrity controller.
  • the RFID tags and readers are installed on part of vehicle units that faces parts of the other vehicles units.
  • each vehicle unit between the first and the last vehicle unit is equipped with at least one RFID reader, preferentially two, and at least one RFID tag, preferentially two, while the first and the last vehicle units are either equipped with a RFID tag or with a RFID reader.
  • the first and the last vehicle units might also be equipped with one RFID reader and one RFID tag in order to be able to communicate with a vehicle unit of another multi-unit vehicle equipped with RFID tag and/or RFID reader according to the invention and that might be coupled to the first or the last vehicle unit of the multi-unit vehicle according to the invention.
  • a RFID tag or a RFID reader might be installed on/close to the front of the first vehicle unit and respectively on/close to the rear part of the last vehicle unit in order to be able to communicate with a RFID reader or tag of a vehicle unit of another multi-unit vehicle that might be coupled to the first or last vehicle unit.
  • each vehicle unit between the first and the last vehicle units is equipped with at least two RFID readers and at least two RFID tags, each RFID reader, respectively RFID tag, of a same vehicle unit being configured and installed for communicating with a RFID tag, respectively RFID reader, of a different vehicle unit.
  • the first and the last vehicle units are both equipped with one RFID tag and one RFID reader for communicating with the RFID tag/reader of the second vehicle unit and respectively of the penultimate vehicle unit.
  • the first and the last vehicle units might also be equipped with an additional pair comprising one RFID tag and one RFID reader for checking the coupling of the first/last vehicle unit with a vehicle unit of another multi-unit vehicle.
  • the present invention proposes to use known RFID techniques and devices for carrying out the system and method according to the invention.
  • the distance at which the RFID reader is still able to identify a RFID tag might be tuned. It is thus possible to define for each RFID reader/tag said threshold distance d over which they will not be anymore capable of communicating with one another.
  • Radio-frequency identification/tracking is done wirelessly and free of any contact between the RFID tag and the RFID reader.
  • each RFID tag according to the invention comprises electronically stored information related to the vehicle unit on which it is or it has to be installed.
  • some or all RFID tags might be powered by and read at short ranges (a few meters) via a magnetic field (electromagnetic induction) generated by the RFID reader, and then act as a passive transponder to emit in return microwaves or UHF radio waves.
  • some other or all RFID tags use a local power source such as a battery for generating the magnetic field and may operate at hundreds of meters.
  • Each RFID Tag according to the invention might be passive, active, or battery-assisted passive. They comprise in particular a circuit connected to an antenna configured for sending a signal to and receiving a signal from the RFID reader with which it cooperates.
  • the signal sent by the RFID tag T k to the RFID reader R k might comprise in particular the data D k and other relevant data related to the vehicle unit on which it is installed, and the signal sent by the RFID reader R k to the RFID tag T k might comprise data related to the vehicle unit on which the RFID reader is mounted.
  • the circuit is at least able to store and process information/data transmitted by the RFID reader or that have to be transmitted to the RFID reader with which it cooperates, like the data D k .
  • Said circuit might be able to modulate and/or demodulate a radio-frequency signal sent to/by the RFID reader and/or to collect DC power from the electromagnetic field generated by the RFID reader.
  • Passive RFID tags according to the invention are free of any battery power supply. Their advantages are to be cheap and easy to be installed/ mounted on any vehicle unit due to their small size. Active RFID tags according to the invention have their own power supply used to supply energy to the circuit and to send periodically information to the RFID reader, notably said data D k .
  • Battery-assisted passive RFID tags according to the invention comprises a battery, but only send information to the RFID reader, e.g. the data D k when they are activated by said RFID reader. Message send to reader is power by the reader antenna energy.
  • the RFID tags according to the invention might be read-only tags, might have a factory-assigned serial number, or might be read/write tags where vehicle unit-specific data are stored in storing means of the circuit of the RFID tag.
  • Each RFID reader R k according to the invention is able to read information stored in the storing means of the RFID tag T k and/or to store information in the storing means of the RFID tag T k .
  • the RFID reader R k according to the invention has Wireless Local Area Network (WLAN) capabilities and is therefore able to wirelessly communicate with another RFID reader of the system according to the invention, or with the integrity controller 11 which comprises in particular means for wirelessly communicating with at least one of the RFID reader R k , R 2k .

  • each RFID reader R k may provide another RFID reader R z ⁇ k with the message M k .
  • the RFID readers R 1 and R N-1 send their respective messages M 1 and M N-1 directly to the integrity controller 11 and/or only to the RFID readers M 2 and M N-2 respectively.
  • the integrity controller 11 is configured for selecting among the RFID readers R k a single RFID reader will first generate a message.
  • the integrity controller orders the RFID reader R 1 or the RFID reader R N-1 to first generate a message M 1 or M N-1 .
  • each RFID reader R k generate a message M k only if it has been selecting by the integrity controller 11 for being the first RFID reader to generate a message M k or if it has received a message M z from another RFID reader, in particular from a directly neighboring RFID reader.
  • the integrity controller 11 may receive any message M k directly from any RFID reader R k , wherein preferentially each RFID reader R k directly sends the message M k to the integrity controller 11 by means of wireless communication.
  • the integrity controller 11 receives only messages comprising information related to the presence or absence of all vehicle units. Preferentially, it receives only the messages M 1 or M N-1 , wherein each of said messages M 1 or M N-1 comprises additional information related to the absence or presence of the vehicle unit U i ⁇ 2 or U i ⁇ N by subsequent incorporation of information related to the presence or absence of a vehicle unit by each RFID reader R k with k ⁇ 1 and k ⁇ N-1.
