Definitions
- the invention relates to a reset method for an axle counter.
- Axle counters are used in railway signaling. Such Axle counters are e.g. known from DE 196 38 956 A1.
- a command for restarting the Section analysis for example via an additional Fermeldetiv transferred to the metering point.
- the command is to restart transmitted via the power supply line to the metering point.
- This Command must not be influenced by influencing voltages on the Power supply line can be generated.
- a reboot is through Turning off the power supply voltage generated.
- the object of the invention is a method for secure transmission of a To provide information about a power line that Interference is exposed and an associated metering point for an axle counter.
- the section evaluation for a counting point of an axle counter is performed by an interlocking system supplied with DC voltage.
- a restart command becomes the polarity of the DC voltage inverted.
- the reverse polarity is detected in the simplest case via a diode.
- each section evaluation will be a coded restart command assigned, e.g. a restart command with a predetermined period of time.
- the Monitoring the duration of a received restart command. Is that lying Duration within a time window, i. between a minimum and a maximum duration, which is specified for the respective section evaluation is, then is the received restart command for each Section evaluation determined and the restart is initiated. Is that lying Time outside the specified time window, then a reboot not initiated.
- a Gritz bridge is planned. It serves to the Power supply for the metering point regardless of the polarity of the Ensure supply voltage. This ensures that Metering points continue to be supplied with power even if a restart is to be performed at a specific point of delivery.
- the Axis counter evaluation can therefore be used to evaluate several Free reporting sections are used.
- Occurs for example, by a short circuit with another line one Reverse polarity (galvanic interference), then becomes a pseudo-restart command generated, but after exceeding the maximum Period is discarded, and thus does not lead to a restart.
- Reverse polarity galvanic interference
- a command to restart can not be caused by an error or a Influencing be generated.
- a cable with Fermeldeeigenschaften is for the transmission of the restart information not mandatory.
- FIG. 1 shows a schematic representation of a Detail of an interlocking internal system according to the invention and a Detail of a metering point according to the invention.
- a railway signaling equipment usually includes, inter alia. 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, with rail contacts are connected.
- the interlocking internal system 1 includes a Umpolscnies 2 for generating restart commands for the At least one point of delivery by reversing the polarity of the emitted Supply voltage.
- a fuse 3 is provided, which in the positive supply voltage branch is inserted and serves to detect a reverse polarity caused by short circuit and to prevention.
- the metering point 4 includes a Grford bridge 5 and a downstream detector 6,8 for detecting a received Restart commands, the one opposite the power supply voltage has inverse polarity for the metering point.
- the detector 6, 8 includes a diode 6 and a converter 8.
- the converter 8 is for example as Opto-coupler executed.
- a switching power supply 7 is provided which the Grford bridge 5 is connected downstream.
- the polarity reversal circuit 2 is in the supply voltage line between Interlocking system 1 and point of delivery 4 connected. It serves to the Reboot commands to generate. A restart command will be generated by reversing the supply voltage, i. e. is inverted.
- 2 relay contacts are in the polarity reversal circuit intended.
- the polarity reversal circuit 2 has control inputs on purpose Control of the relay contacts. The activation takes place e.g. about one 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. This is the Voltage supply ensured uninterrupted, even during a restart command. This is particularly advantageous in the Connection of several metering points to a polarity reversal circuit via the same Supply lines, as well as the metering points continue undisturbed in Operation can remain when a specific 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 calculator can also be a dual-computer system or a three-computer system.
- the calculator is also with converter 8 connected. Detects detector 6, 8 a restart command, so will communicated this to the computer, which then performs a reboot.
- the polarity reversal circuit 2 is suitable Restart commands with at least two different time periods generate, with at least two metering points having restart commands are assigned to different durations.
- Polarity reversal circuit 2 is e.g. connected via first supply lines to point of delivery 4 and over second supply lines with another point of delivery.
- the restart command for point of delivery 4 is e.g. formed by Umpolung the Supply voltage for 3 seconds.
- the restart command for the another point of delivery is e.g. formed by Umpolung the Supply voltage for 5 seconds.
- a restart in the metering point 4 takes place only when a restart command is received for 3 seconds, not if a restart command is received for 5 seconds.
- a restart command with 3 seconds is provided.
- Such received command lies in the given time window and causes a reboot.
- the monitor a time window of 4 to 6 seconds.
- a received restart command with 5 seconds lies in the given time window and causes a restart.
- the durations of the Restart commands in the interlocking system 2 programmable, e.g. for installation and / or during operation.
- the Time window of the counting points programmable, e.g. telemetrically through the Interlocking system 2. This provides a flexible allocation of Reboot commands realized the whole Railway signaling system flexible for extensions and Changes in the topology and number of metering points holds.
