Definitions

  • the present invention relates to a method and a system for processing a planned switch chain in order to achieve circulation of one or more switches in rail-bound traffic.
  • decentralized signal box structures As digitalization moves into the control and/or monitoring of rail traffic, there will be an increasing reduction in decentralized signal box structures.
  • the decentralized signal box structures are increasingly being converted into central signal box structures that cover very large areas.
  • a reduction in this regard to two or three central signal boxes could be planned for the Swiss Federal Railways network, which would then ensure 24-hour operation. Since these changes will also take place over a period of many years to protect investments in the already installed base, the requirements for the decentralized signal box structures will increase massively, especially with regard to response times and latency times, especially since at the same time there is usually always an increase in efficiency should be achieved in the existing network.
  • Siemens Mobility AG has developed signal box structures under the name Sinet ® , in which data is exchanged between the so-called element controllers and LEUs (Lineside Electronic Unit), which are arranged on the track to control switches , signals, balises, axle counters and the like, and a central signal box is provided via a redundant data line.
  • Communication units (SCU) to which the element controllers are used are connected, integrated into the data line in ring structures.
  • the electrical supply and monitoring of currents from the signal box are delegated to the local element controllers, which are connected to a power bus that is also redundant and thus obtain their power locally with the advantageously associated short cable routes.
  • the coupling unit required for this is referred to as the network node unit SND, which is also coupled to the communication unit SCU and exchanges bidirectional data with it, for example about the strength of the flowing current and function characteristics and the like.
  • These power supply structures are currently sold by Siemens Mobility AG under the name Sigrid ® .
  • Sinet ® and Sigrid ® are, for example, in the European patent EP 2 301 202 B1 described.
  • the document EP2549620A2 discloses a method for the decentralized control of switches.
  • Decentralized functional units are connected to a ring line and have external power supplies for powering the point drives.
  • the present invention is therefore based on the object of specifying a method and a system for processing a planned switch chain in order to achieve the circulation of one or more switches in rail-bound traffic, which meet the above-mentioned requirements.
  • the simultaneous starting of several switches can be reliably prevented by specifically allowing the switch running chain in only a single communication unit of the plurality of communication units arranged in the data line ring, whereby the power bus supplying the switch motors can be designed for a significantly lower peak load.
  • the delay time until all circulation commands are processed is essentially only determined by the times until the switch-on current falls below the predeterminable value summed up at the individual switches. Additional communication times to the signal box that further delay processing do not occur here because local communication only occurs in the data line ring.
  • the delay is a maximum of ten times the time required for the starting current to fall below a predeterminable threshold. Assuming a time period of 200 ms per switch, there would be a maximum delay of 2s for the ten switches until the last circulation command would be processed. Such a short period of time can easily be tolerated even when the network is busy.
  • the communication units carry out a functional test of their communication units arranged adjacently in the data ring line at regular intervals and in the event of a failure of a communication unit that is currently blocking the switch chain the turnout chain is released again and blocked by the next communication unit configured in the turnout chain.
  • FIG. 1 shows a schematic representation of a system 2 for controlling and monitoring rail traffic on a track section 4.
  • this track section there are four switches W1 to W4 and a level crossing BUe.
  • a control system 6 is provided in the present case, in which a plurality of dispatcher workstations are usually provided.
  • the dispatchers monitor the scheduled settings of routes and intervene manually in the control of the train's movement if there are deviations from the timetable.
  • the request for setting a route is transmitted from the control system 6 to a signal box 8, which today usually includes a signal box computer 10 as well as other data resources and control cabinet infrastructure 12.
  • Both the control system 6 and the signal box 8 connect to a redundant data backbone 16a, 16b (e.g. OTN, SDH, UMUX or similar) for data exchange using routers/switches 14.
  • the data backbone 16a, 16b can be used to bridge almost any distance.
  • Each switch W1 to W4 can include one or more switch motors, each of which is controlled by an Element Controller EC.
  • These element controller EC are logically arranged within a combined communication and network node unit.
  • the communication unit SCU1 to SCU5 establishes the connection to a data ring line 20 via the element controllers, which are designed at SIL4 level Interlocking 8 can exchange data.
  • the network node units SND1 to SND5 couple to a power bus 22, which is also designed as a ring line, and supply the element controller EC with the electrical power required to operate the switch motors.
  • the energy bus 22 itself is supplied with the required electrical power at feed points ES1, ES2 remote from the central signal box 8. These feed points ES1, ES2 can, for example, also be arranged in fixed structural structures, such as transformer houses TH1, TH2.
  • the communication of the network node units SND1 to SND5 with the associated communication units and/or with the signal box 8 is also handled via the communication units SCU1 to SCU5.
  • a switch chain is first of all configured for the switches W1 to W4 administered in this data ring line 18, which is stored in each communication unit SCU1 to SCU5 and here, for example, regulates the order in which the individual switches W1 to W4 should circulate.
  • each communication unit SCU1 to SCU5 is capable of temporarily blocking this switch chain for all other communication units SCU1 to SCU5 integrated in the data ring line 18.
  • a staggered processing of these circulation commands is ensured in that a first communication unit, here for example the SCU1, of the communication units SCU1 to SCU5 is configured in such a way that, after receiving a switch changeover command, it runs the planned switch running chain for the other communication units arranged in this data ring line 18, here the SCU2 to SCU5, and processes the switch circulation commands received for the element controller EC 1i connected to this first communication unit SCU1.
  • the network node unit SND1 detects the switch-on current recorded by the switch motor or switch motors and reports to the communication unit SCU1 when the switch-on current has again fallen below a predeterminable limit value. In response to this reported fall below the limit value for the inrush current, the configuration of the communication units SCU1 to SCU5 then provides for the blocking of the turnout chain to be lifted again and the turnout chain to be released to the second communication unit configured in the turnout chain, here for example SCU2, is carried out. At this point it should also be mentioned again that for the processing of all turnout commands, it is irrelevant which of the communication units is the first to take possession of the turnout chain and temporarily block it for all others.
  • the second communication unit SCU2 configured in the turnout chain now takes possession of the turnout chain and blocks it for the other communication units SCU1, SCU3 to SCU5.
  • the switch W2 can rotate, whereby After the inrush current falls below the limit value, the blocking of the turnout chain is lifted and taken over by the next communication unit configured in the turnout chain, here eg SCU4.
  • This procedure can now be repeated for one additional communication unit, here only SCU5, until the last switch circulation command has been processed in accordance with the planned switch running chain for the switches W1 to W4 administered in this data ring line 18.
  • the switch chain is not taken over by the communication unit SCU3 because no switch circulation command has been issued for the communication unit SCU3, which is only intended for the level crossing BUe. It should also be noted that it is irrelevant at which communication unit SCU1 to SCU5 the first turnout command arrives, since the order of the communication units blocking the turnout chain results from the turnout chain. For example, in this exemplary embodiment, if the communication unit SCU4 for the switch W3 were to block the switch chain first, the switch chain would then be processed according to the configuration in the further order SCU5 for switch W4, SCU1 for switch W1 and SCU2 for switch W2.
  • the communication units SCU1 to SCU5 can now each be configured in such a way that a functional test of their neighbors in the data ring line 18 is carried out at regular intervals arranged communication units can be carried out.
  • the communication units can, for example, send short live requests to their respective neighbors. If there is no reply, there is probably a malfunction in the non-responsive communication unit. If the communication unit that is currently blocking the switch chain fails, the switch chain is then immediately released again, so that the switch chain can be taken over by the next communication unit configured in the switch chain and blocked again for the remaining communication units arranged in the data ring line.
  • each communication unit SCU is associated with a network node unit SND for the electrical supply of the respective communication unit SCU and the element controller EC connected to it, with the communication unit SCU also sending an alive request at regular intervals their associated network node unit SND sends. If there is no response, this is interpreted as a failure of the network node unit SND.
  • the switch chain blocked by the assigned communication unit SCU is immediately released and can thus be taken into possession of the next communication unit configured in the switch chain.
