Definitions

  • the invention relates to a circuit arrangement for monitoring the occupancy status of a switch or a track area according to the preamble of claim 1 must be guaranteed that a subsequent Vehicle cannot switch the switch if there is still one vehicle in front is located in the area of the switch. Independently the track section may only be of the train length again be released if the metal mass of the last car has left the effective range.
  • This effective range is a 6th up to 12m long track section, which uses a capacitive Connection between the rails and the inductors of the Rails is designed as an NF (low frequency) resonant circuit.
  • An external evaluation device detects damping and Change in resonance frequency during navigation by a Rail vehicle caused by axle short circuit and damping caused by the iron mass of the car body. As an axle short circuit when driven by a road vehicle, for example at a level crossing can distinguish between wheeled and rail vehicles.
  • a detector circuit known as turnout blocking circuit MC-WSK from Siemens AG relies on an oscillator whose feedback through the track circle. In the event of damping or upset the oscillation of the track breaks off, what is interpreted as driving. With this detection principle is the EMC resistance (electromagnetic compatibility) conceptually limited. Faults caused by inverters modern vehicle controls or strong radio transmitter can hardly be mastered. Beyond that fail-safe properties at component level for this detector be detected. Because this type of security verification no longer corresponds to modern developments a high admission risk.
  • the well-known detector circuit requires a complicated comparison and the use of Special measuring devices as part of the commissioning. Automation as well as effective self-diagnosis are not possible.
  • the object of the invention is to overcome these disadvantages eliminate and a circuit arrangement of the generic type Specify type, which is characterized by improved immunity and distinguishes increased functional reliability.
  • the circuit arrangement enable detection of the damping and resonance frequency change by correlating the in and out of the track circle decoupled signals.
  • the differentiation between track circuit influence by axis short circuit or iron mass by evaluating the level of the correlation voltage. On this way you can choose between occupancy by a rail vehicle or a road vehicle can be distinguished.
  • a synchronous rectifier for comparison of the coupled with the decoupled LF signal and a Controller provided for evaluating the correlation signal.
  • A occurs at the output of the synchronous rectifier DC correlation signal, the level of which depends only on the Amplitude and the phase offset of the decoupled from the track circuit Signal depends.
  • the evaluation of the correlation voltage done by the controller takes into account the exact frequency fed in correspond. Interference frequencies largely compensate each other in a low pass following the synchronous rectifier.
  • the controller enables extensive automation sequential control and signal evaluation. Adjustment and commissioning simplify themselves. Special measuring devices not required.
  • the controller that has all the relevant control parameters and processed evaluation data, allows an effective Self-diagnosis. This means that in the event of a fault, the fault can be quickly identified possible. Fail-save properties of individual Components that have the property insulation strength going out are not required.
  • the safety record keeping can be done at the level of observation units, so the admission risk over the known Detector device is reduced.
  • the frequency stabilization in the Resonance frequency to be coupled into the track circuit by the controller controlled.
  • This type of external control allows one Improvement of the signal / interference ratio by increasing the power coupled into the track circuit. This gives a significant increase in EMC resistance.
  • a second controller for redundant safety-relevant evaluation of the correlation voltage be provided.
  • the single figure shows a block diagram of a switch blocking circuit correlation detector.
  • a track circuit 1 which forms an oscillating circuit from rail regions 2a and 2b forming inductors and a capacitor 3.
  • An NF signal with a frequency of 20 to 30 Hz is coupled into this track circuit 1.
  • a first controller 4 is used, which is connected to the track circuit 1 via a PLL (phase locked loop) component 5 and an output stage 6.
  • the frequency to be coupled in is controlled by the controller 4, f oszsoll , the PLL element 5, f oszist and amplified by means of the output stage 6.
  • the unamplified input signal and an output signal of the track circuit 1 are routed to a synchronous rectifier 7, which after a phase adjustment 8 overlaps the two signals and generates a correlation signal.
  • This DC voltage correlation signal is fed to the controller 4 via a low-pass filter 9.
  • the coupling-in signal and the coupling-out signal are each also routed to the controller 4 via a peak value rectifier 10 and 11.
  • Both the sequence control and the evaluation of the correlation voltage U correlation are carried out by the controller 4. If the track circuit 1 is traversed by a rail vehicle, the oscillating circuit is considerably damped by the axle short circuit and the iron masses of the car body, so that the decoupled signal differs significantly from that injected signal differs. This difference is detected by correlating the two signals by means of the synchronous rectifier 7 and fed to the controller 4 for level evaluation. Ultimately, the controller 4 generates an output signal which triggers a free or busy message 12 of the track section under consideration.
  • the controller 4 can be connected to a diagnostic module 13, which queries certain parameters, and / or a diagnostic device 14, which evaluates controller states.
  • a second controller 4.1 can be provided for redundancy purposes be the same as the first controller 4 with a second Low-pass filter 9.1, a second synchronous rectifier 7.1, a second phase adjustment 8.1 and a second peak value rectifier 10.1 is connected.
  • the invention is not limited to the above Embodiment. Rather, there are a number of variations conceivable, which is also fundamentally different Execution make use of the features of the invention.
