Definitions

  • the invention relates to a reset method for an axle counter.
  • Axle counters are used in railway signaling technology.
  • a command to restart the Section evaluation for example via an additional communication cable transmitted to the point of delivery.
  • the command to restart transmitted to the metering point via the power supply line. This Command must not be exerted on the Power supply line can be generated. A restart is done by Switching off the power supply voltage generated.
  • the object of the invention is to provide a method for the secure transmission of a To provide information about a power line that Is exposed to interference and an associated point of delivery for an axle counter.
  • the section evaluation for a point of delivery of an axle counter is carried out by an interlocking system supplied with DC voltage.
  • a restart command will change the polarity of the DC voltage inverted.
  • the polarity reversal is recognized by a diode.
  • every section evaluation becomes a coded restart command assigned, e.g. a restart command with a predetermined period of time.
  • the Duration of a received restart command monitored. Is that Duration within a time window, i.e. between a minimal and a maximum duration specified for the respective section evaluation is, the received restart command is for the respective Section evaluation is determined and the restart is initiated. Is that Time outside the specified time window, then a restart not initiated.
  • a Griger bridge is provided at the point of delivery. It serves the Power supply for the point of delivery regardless of the polarity of the Ensure supply voltage. This ensures that Metering points continue to be powered even when on a restart is to be carried out at a certain point of delivery.
  • the Axle counter evaluation can therefore be used to evaluate several Clearance sections are used.
  • a command to restart cannot be caused by an error or a Influence can be generated.
  • a cable with communication properties is for the transmission of the restart information not mandatory.
  • FIG. 1 shows a schematic representation of a Detail from an interlocking system according to the invention and one Detail from a point of delivery according to the invention.
  • a railway signaling system usually includes a Interlocking system and at least one metering point with Section evaluation for an axle counter, the over Power supply lines are interconnected.
  • An axle counter usually includes two points of delivery, those with rail contacts are connected.
  • the interlocking system 1 includes a Reverse polarity switch 2 to generate restart commands for the at least one metering point by reversing the polarity of the transmitted Supply voltage.
  • a fuse 3 is provided, which in the positive supply voltage branch is inserted and serves to to detect and reverse a polarity reversal caused by a short circuit prevention.
  • the metering point 4 includes a Grford bridge 5 and a downstream detector 6,8 for the detection of a received one Restart commands, one versus the power supply voltage has inverse polarity for the point of delivery.
  • the detector 6, 8 includes a diode 6 and a converter 8.
  • the converter 8 is, for example, as Opto-coupler implemented.
  • a switching power supply 7 is provided the Grford bridge 5 is connected downstream.
  • the polarity reversal circuit 2 is in the supply voltage line between Interlocking system 1 and metering point 4 switched. It serves the Generate restart commands.
  • a restart command is given generated by reversing the polarity of the supply voltage, i.e. is inverted.
  • the pole reversal circuit 2 has control inputs for the purpose Control of the relay contacts. The control takes place e.g. about a Software program.
  • the Griger bridge 5 serves to supply the voltage for the Switching power supply 7 and the point of delivery 4 for the normal case and for the case to provide a reversed supply voltage. So that's it Power supply guaranteed continuously, also during a restart command. This is particularly beneficial in the Connection of several metering points to a pole reversal via the same Supply lines, because the metering points remain undisturbed in Operation can remain if a certain point of delivery by a restart command is prompted to restart.
  • Switched-mode power supply 7 does not supply the supply voltage for one illustrated calculator.
  • the computer can also be a double computer system or be a three-computer system.
  • the calculator is also with converter 8 connected. If detector 6, 8 detects a restart command, then this is communicated to the computer, which then carries out a restart.
  • the polarity reversal circuit 2 is suitable Restart commands with at least two different time periods generate, with at least two metering points restart commands with are assigned to different durations.
  • Polarity reversal circuit 2 is e.g. connected to metering point 4 via first supply lines and via second supply lines with another metering point.
  • the restart command for point of delivery 4 is e.g. formed by reversing the polarity Supply voltage for 3 seconds.
  • the restart command for the another point of delivery is e.g. formed by reversing the polarity Supply voltage for 5 seconds.
  • a restart in point of delivery 4 takes place only take place if a restart command is received for 3 seconds, not if a restart command is received for 5 seconds.
  • the Griger bridge 5 in each Metering point only enables the evaluation of the time period. Without it would each point of delivery upon receipt of a restart command to one Restarted; it can be used for an individual evaluation and individual metering points can be addressed.
  • the unaffected Metering points continue to work without restriction.
  • the point of delivery calculator 4 is programmed to monitor whether that received restart command within a specified Time window. For example, it monitors whether the restart command lies within the time window 2 seconds to 4 seconds. For point of delivery 4, a restart command is provided with 3 seconds.
  • Such one received command is within the specified time window and initiated a restart.
  • a calculator available that monitors a time window of 4 to 6 seconds.
  • a received restart command with 5 seconds lies in the specified time window and initiates a restart.
  • the time periods are Restart commands programmable in the signal box system 2, e.g. for installation and / or during operation.
