Definitions

  • the invention is related to a system for redundant transfer of information from a system detecting free status of track sections to a signalling system, in particular to a station system, a linear lock system, a junction signalling system and a method of redundant transfer of such information, in particular if high availability of railway system using serial communication is required.
  • Systems required to provide particularly high availability levels include systems detecting free status of track sections commonly used in railway traffic control systems. Malfunctions of their functioning are directly reflected in perturbation of railway traffic, negatively impacting its continuity and safety.
  • the goal of this invention is to develop a solution ensuring high availability of a railway traffic control system.
  • the communication system within each of the control modules comprises at least one communication controller, preferably installed in a processor system with at least one Ethernet switch system equipped with at least two ports connected to at least two, preferably independent communication buses ensuring connection with other control modules comprising the system detecting free status of track sections.
  • the method of redundant information transfer from the system detecting free status of track sections to the signalling system, in particular to a station system, a linear lock system, a junction signalling system is characterised in that according to the invention, the system detecting free status of track section provides information stored in the local memory of the set of n control modules and sent to the signalling system as ordered, individual information signals, wherein each and every single information signal is formed from at least two unit signals obtained from previously identified control modules from the set of n control modules according to a previously specified selection rule for individual control modules.
  • the ith unit signal is obtained by processing information stored in the ith control module, while the jth signal is obtained by processing information stored in the jth control module according to the same processing algorithm implemented in control modules.
  • the j-information is obtained in the jth module by copying the i-information sent from the ith control module during a period no longer than a period previously defined in the system detecting free status of track sections.
  • ith and jth signals are sent in parallel to the signalling system using the appropriate communication system.
  • Fig. 1 presents a schematic diagram of a single control module
  • Fig. 2 presents a simplified diagram of connections in a peer-to-peer system between 1, 2, . n control modules
  • Fig. 3 presents a diagram of redundant information transfer between ith control module and jth control module.
  • the system detecting free status of track sections 1 includes n control modules Mk 1,2,...n, in which one interface unit UI is installed, ensuring connection between the system detecting free status of the tracks S1 and the signalling system S2.
  • Each of the control modules Mk 1,2...n uses an interface unit UI connected to the corresponding processor unit UP.
  • Each of the processor units is provided with local memory MEM and the corresponding communication system COM.
  • Control modules Mk 1,2...n are interconnected using a communication bus conforming to the 802.3 Ethernet standard and to safe transmission standards using cryptographic techniques.
  • Each of the control modules Mk 1,2...n is characterised by identical software-hardware design, while processor systems SP of the individual control modules Mk 1,2...n are interconnected using virtual logical peer-to-peer connections.
  • the communication system COM within each of the control modules Mk 1,2...n forms a single communication controller built into the processor unit UP with one Ethernet switch system provided with two ports connected to two independent communication buses ensuring connection with other.
  • Information transfer from the system detecting free status of track sections S1 to the signalling system S2 of the station system takes place such that the system detecting free status of track sections S1 is provided with information PK stored in the local memory MEM of the set of n control modules Mk 1,2...n and sent to the signalling system S2 as ordered, individual information signals SYG.
  • Each individual information signal SYG is formed using at least two unit signals SYGi and SYGj obtained from previously identified unit control modules MKi and MKj included in the set of n control modules Mk 1,2...n according to a previously specified selection rule.
  • the SYGi signal is obtained by processing information stored in the control module MKi and the SYGj signal is obtained by processing information stored in the Mkj module according to an identical processing algorithm implemented in control modules Mk 1,2...n .
  • the j-information is obtained in the Mj module by copying i-information sent from the Mi module during a period not longer than the period previous specified in the system detecting free status of track sections S1.
  • the obtained SYGj signal is sent to the S2 signalling system in parallel to the SYGI signal using the appropriate communication system COM.
