Definitions

  • the invention relates to railway control systems.
  • railway control apparatus includes time division multi-plexing means for communicating between equipment locations in a railway system, at least one of the locations being provided with time division multi-plex transmitting means and at least the remaining locations with time division multi- p lex receiving means.
  • time division multi-plexing means comprises a plurality of independent multi-plex receiving/transmitting system and the receiving means at each location is provided with signal comparison means responsive to the independent multi-plexed signals to pass the signals only when a majority of the or all of the signals agree.
  • the interlock sub-systems 1, 2 and 3 are connected to T.D.M. transmitters 4, 5 and 6 respectively which transmits the signals via pairs of cables 7, 8 and 9 to T.D.M. receivers 10, 11 and 12 located at a wayside equipment. It will be understood that the cables 7, 8 and 9 will continue on to connect to further T.D.M. receivers in other wayside equipments but that these are omitted here for clarity.
  • the outputs of the three receivers 10, 11 and 12 are connected to both a majority voting circuit 13 and an out-of-coincidence circuit 14.
  • the voting circuit 13 compares the three received signals and if all of or a majority of the signals are equal that signal is taken as correct and is gated to the output 15 of the rating circuit.
  • the out-of-coincidence circuit 14 is responsive to any of the signals being in disagreement to provide an alarm output 16 which indicates that a failure has occurred.
  • the three T.D.M. links need not be, but preferably are, synchronised in their operation. If the links are asynchronous it will be necessary to provide temporary signal storage facilities between the receivers and the voting and out of coincidence circuits.
  • the interlocking system 1 receives information from wayside equipments relating to the operative states of control devices, such as track occupancy circuits, signals and points. Signals representing the states of these devices are supplied to a wayside equipment T.D.M. transmitter 17 which multi-plexes the information onto cable 18 connected to T.D.M. receiver 19 back at the interlock room. The information is demulti-plexed and supplied to a voting circuit 20 and out of coincidence circuit 21. The signals 22 then determined as correct are supplied to the interlocking system 1 for the normal interlock control functions to be performed.
  • wayside equipments relating to the operative states of control devices, such as track occupancy circuits, signals and points.
  • Signals representing the states of these devices are supplied to a wayside equipment T.D.M. transmitter 17 which multi-plexes the information onto cable 18 connected to T.D.M. receiver 19 back at the interlock room.
  • the information is demulti-plexed and supplied to a voting circuit 20 and out of coincidence circuit 21.
  • the signals 22 then determined
  • Fig. 2 the complete triple redundancy circuits are not shown for the sake of clarity. It will also be understood that the cables 7 and 18 may be the same cable. Thus for a triple redundant T.D.M. system the cable in each sub-system may be used for transmission in both directions.
  • each T.D.M. link to the interlock system may be connected directly to one of the interlock sub-systems, in this case only the majority voting circuit 13 in Fig. 2 is retained for correlating signals received from the interlock sub-systems.
  • the three systems operate independently except in so far as they receive inputs from common sources and provide outputs to control the same devices.
  • FIG. 3 this shows a railway signalling system again with triple redundancy.
  • a control panel 30 can be used to feed information, for example route information, into a supervisory computer 31.
  • the computer displays information relating to track occupancy, train movements etc. by means of a visual display unit (V.D.U.) 32 and also supplies information, such as anticipated route forming control signals to an interlocking computer system 33.
  • the computer 31 also receives information from the interlocking computer 33 relating to track occupancy states and the settings of signals and points.
  • Computer 31 can also transmit signals to and receive information from a satellite interlocking system 34.
  • the interlocking systems 33 and 34 are both linked to outside locations by triple redundancy T.D.M. links as described with reference to Figs. 1 and 2.
  • various outputs in the signalling system may be recorded in a "black box” type accident recorder so that should an incident occur the recorded signals can be checked to see if the incident was due to control failure.
