Definitions

  • Such a beacon is known in particular in a signaling system compliant with the ETCS standard (for "European Train Control System” in English) and more particularly subset 036 relating to the "A" interface.
  • It comprises signaling equipment 6 arranged along a track 4.
  • the state of this equipment may take different values in a defined set of predefined values.
  • the state of the equipment 6 is controlled by the control state of a relay 12.
  • the control state of the relay 12 is a function of a setpoint signal S c generated by a remote switching center 14 and applied to the relay 12.
  • Some contacts of the relay 12 are free: their individual engagement state corresponds to the control state of the relay 12, and therefore to the state imposed on the equipment 6.
  • the beacon 120 which makes it possible to transmit to the train 2 information relating to the state of the signaling equipment 6 is connected to the relay 12 via an encoder 110.
  • the encoder 110 comprises an acquisition means 112 for determining the individual engagement state of a free contact of the relay 12; selection means 114 able to select, from a list stored in the encoder 110, a telegram associated with the determined individual engagement state; and an interface means 116 capable of transmitting, to the beacon 120, a message C whose payload corresponds to the selected telegram.
  • the beacon 120 includes an interface means 122 capable of receiving the message C transmitted by the coder 110; decoding means 123 capable of decoding the received message C and placing the telegram contained in this message C in the memory 28 of the beacon 120; and a transponder 24 capable of transmitting a radio signal S corresponding to the telegram placed in the memory of the beacon.
  • the beacon 120 also includes an electrical power management module 126 which is clean, when it is influenced by a conjugated module 46 which is provided with a reading device 40 on board the train 2, to generate a power supply current. transponder 24 of the beacon 120.
  • the encoder 110 operates continuously so as to detect any change in the individual engagement state of the free contact, i.e., any change of control state of the relay 12. As a result, the encoder 110 must be connected to a source of electrical power 118.
  • the encoder 110 sends a message C to the tag 120 with the new telegram to be taken into account.
  • the encoder 110 must then provide sufficient electrical power to the beacon 120 so that the latter processes the message C.
  • an encoder In the first place, an encoder must be added to the feet of the signaling equipment, which it is desired that signaling information be resumed on board the train.
  • This encoder must be protected from external aggressions. It is therefore to place it in a housing, which can be the housing 10 protecting the relay 12, but which is often an additional housing. This represents a cost in terms of equipment and footprint at the foot of the equipment.
  • An encoder is a calculator. It therefore has many components. It represents a significant investment and maintenance cost. In addition, its availability is limited, which has the effect of reducing the functional availability of the tag 120 and those of other tags that may be connected to it.
  • An encoder must be permanently powered. It consumes an electrical power of the order of 2 to 20 W. The operation of the encoder therefore increases the cost of operating the signaling system as a whole.
  • the document EP 2 340 977 A1 discloses a system comprising a beacon for operating in ETCS level 1 while passing an encoder, but only in a limited supervision mode (SL "limited supervision") of this level.
