Definitions

  • the invention relates to an on-board communication system aboard a railway vehicle for transmitting information with tags placed on the ground and relates in particular to a communication system for tram.
  • the chain of transmission usually consists of an on-board antenna associated with a amplifier / adapter housing having as output links for the transmission of signals to or from the antenna, these links being connected to an interface card of an evaluation module carrying out the processing of data.
  • Such an amplifier / adapter housing is supplied with electricity by power lines connected to a vehicle power supply unit.
  • Such communication systems are used in particular in tag speed control, such as the KVB system used in France by the National railway Company (SNCF), each vehicle being informed at passage of a beacon on the state of the signaling, a calculator of the module constantly checking that the speed of the vehicle is compatible with the signaling encountered and imposing if necessary an emergency stop.
  • SNCF National Railway Company
  • the SNCF requires that the distance between the vertical axis of the antenna and the axis of the axle before it is not more than 12 m.
  • Such a value may however vary in function of the operating companies since it is a function, in particular, of the location of the ground beacons in relation to the infrastructure.
  • the distance between the extreme axles of the same vehicle may not exceed 24 m when the vehicle has only one antenna.
  • each car is then equipped with an antenna 21 disposed at a distance d ⁇ 12 m from the front axle 11.
  • the antenna 21 is associated with a housing amplifier / adapter 22 from which come out of the connecting wires 6 which are connected to an interface card of an evaluation module 3 embarked on the car 10.
  • Each housing amplifier / adapter 22 is powered electrically by lines 5 connected to a power supply card present in the module evaluation, this card itself being powered by a power supply unit 9 disconnectable by means of a switch 7.
  • the evaluation module 3 of each car is connected to a viewing panel 8 on which are displayed the different information communicated in the passage of beacons 1 and in particular the possible emergency stop orders.
  • an object of the present invention is to provide a communication system that can operate with two antennas distant from each other and that is simple and economical to achieve.
  • the subject of the invention is an onboard communication system on board of a railway vehicle for transmitting information with tags disposed on the ground, characterized in that it comprises two transmission chains each constituted by an antenna associated with an amplifier / adapter housing, the transmission lines being connected to the same evaluation module ensuring the processing of the signals picked up or transmitted by one of the antennas at the passage of the beacons, each amplifier / adapter housing being powered electrically by the same power unit and having connection wires for connection to a evaluation module interface board and in that the system comprises means switching device for alternately connecting the interface card of the unit evaluation of the connecting wires of one or the other of the transmission chains, the antenna belonging to the transmission chain whose connecting wires are not connected to the interface card by the switching means being put into a state inactive so as to have limited energy consumption.
  • the invention also relates to a railway vehicle characterized in that comprises a communication system as previously described.
  • Figure 2 represents tramway consisting of two cars 10, these cars 10 having a common central axle 12 and a front axle 11 arranged nearby the end of the car 10.
  • the tram is equipped with a control system of tagged speed that uses a communication system allowing the exchange information with tags 1 disposed on the ground.
  • This communication system has two ground / tramway transmission lines 2, spread over both cars 10, which are intended to be used alternately depending on the direction of moving the tramway.
  • the two transmission chains 2 are connected to a single module 3 carried by one of the cars 10, this module 3 ensuring the processing of data received or transmitted through both transmission lines 2 in the passage tags 1.
  • the evaluation module 3 further comprises, in the case of speed control by tags, a calculator that verifies that the speed of the vehicle is in accordance with the indications of signals communicated by beacons 1 and transmits information driving at visualization panels 8 placed at each end of the tramway in a driving cabin.
  • each transmission chain 2 of the transmission system communication is carried by one of the cars 10 and is made of a box adapter / amplifier 22 associated with an antenna 21 which is arranged under the car at a distance of less than 12 m from the axis of the front axle 11.
  • These antennas 21 associated with their adapter housing / amplifier 22 are for example in accordance with those usually used in the KVB system of speed control of the SNCF, the adapter / amplifier housing 22 being connected to the antenna by cables of link 23 with a length of about 6 m, the antenna 21 emitting on a length of 27 Mhz and receiving signals on a wavelength of 4.35 Mhz.
  • each adapter / amplifier box 22 is powered by two power lines 0 and 12 V continuously for the emission and two supply lines 0 and 12V continuously for the reception, these lines being represented by a single feed line 5 in FIGS. to simplify the figures.
  • the supply lines 5 are connected to a card supply 31 of the evaluation module 3 which is itself powered by a unit power supply 9 of the tramway.
  • the supply lines 5 of the two housings 22 are connected directly to the power supply board 31 of the evaluation module 3, the lines power supply 5 equivalent voltage of the two housings 22 being connected in parallel, no relay being present on the supply lines 5 between the unit 9 power supply and the housing adapter / amplifier 22.
  • Each adapter / amplifier housing 22 also comprises five links transmitting the signals picked up or transmitted by the antenna, these links being represented by a single wire 6 in Figures 2 and 3.
  • the connecting son 6 are connected to a switching module 4 comprising a relay 41 for each of the connection wires 6 from the housings 22 of the two transmission chains 2.
  • These relays 41 including the guaranteed mechanical characteristics allow a safe control of their state, connect the connecting wires 6 from the housings 22 of the two chains of transmission 2 to either an interface card 32 belonging to the evaluation module 3 or to a plug card 42 belonging to the switching module 4.
  • the different relay 41 of switching module 4 have switching commands dependent so that when the connecting wires 6 of one of the housings 22 are connected with the interface board 32 of the evaluation module 3, the connection wires 6 of the other housing 22 are connected to the plug board 42.
  • the interface board 32 of the evaluation module 3 is connected to a computer which provides the data processing and development of driving information signals on viewing panels 8.
  • the plug card 42 has a structure equivalent to the interface card 32 of the evaluation module 3 and makes it possible to charge with a suitable impedance the son of link 6 that are connected to it so that the latter do not behave like antennas disturbing the signals transmitted by the transmission chain 2 which is connected to the evaluation module 3.
  • the plug card 42 further comprises means for positioning inactive of the antenna 21 associated with the housing 22 which is connected to it so that this antenna 21 has a limited power consumption while being off on transmission and the reception.
  • this setting inactive position of the antenna is carried out by a simple crossing of two connecting wires 6 at the entrance of the card plug 42 relative to the equivalent connections of the connecting son 6 on the interface card 32.
  • the communication system thus produced will advantageously be equipped with a card 31 standard power supply usually intended to power a single antenna 21.
  • the power supply card 31 simultaneously feeds both housings 22, the latter are respectively connected to an active antenna 21 and a antenna 21 inactive.
  • the housing 22 associated with the inactive antenna 21 consumes very little energy and the power consumed by this housing 22 is negligible in front of the power demanded by the housing 22 connected to the antenna 21 active, which allows to use a power supply card 31 usual, ie slightly power greater than the power consumed by a single housing 22 associated with an antenna active 21.
  • Such a communication system is particularly advantageous because it allows, at relays, to select one or the other of the two transmission lines connect to the evaluation module according to the direction of traffic of the tramway while having voltage drops in the power lines minimized to the maximum since no switching element is placed on the lines Power.
  • the inter-antenna distance is limited by voltage losses in the supply lines, too much distance between the power supply unit and the adapter / amplifier box leading to a insufficient power at the level of these. So, such a system allows to offer the inter-antenna distance closest to the theoretical maximum value for a given power of the power unit.
