Definitions

  • the invention relates to a circuit arrangement for monitoring the presence of rail vehicles within certain track sections by means of two induction loops, the changes in inductance of which are each detected by an oscillator, the oscillations of which are converted into square-wave pulses and divided in a frequency divider, and are fed to an evaluation circuit connected downstream of the frequency dividers, which are supplied as a function of the emits a busy or clear message for each change in inductance, the circuit arrangement also having means which enable the direction of travel to be determined by comparing the two messages originating from the evaluation circuit over time.
  • a circuit arrangement of the type described above is known from DE-A-31 00 724, both oscillators being connected to a common evaluation circuit via a changeover switch.
  • the oscillators operating at different frequencies vibrate constantly, although only one oscillator frequency is evaluated at a time.
  • An electronic counter is used as the switch, which receives its switch pulse from the oscillator frequency currently being evaluated. This has the disadvantage that there is no switching process if the oscillator currently being evaluated fails. Since the failed oscillator remains connected to the evaluation circuit, the entire system becomes ineffective.
  • Another disadvantage of the known circuit arrangement is that when the oscillator frequency changes, for example due to environmental influences, the changeover switch switches in a time interval which is changed in the same way, because the changeover process is dependent on the respective oscillator frequency. Monitoring the switch is therefore not possible.
  • the known circuit arrangement finally has the disadvantage that couplings, referred to as beats, can occur between the two constantly oscillating oscillators via the iron masses of the rail vehicles, as a result of which Difference between the different oscillator frequencies is canceled and a clear assignment of the individual frequencies to their respective oscillators is no longer sufficiently possible.
  • this assignment is absolutely necessary for determining the direction of the rail vehicles. Even if the frequencies of the oscillators change significantly due to a failure of frequency-determining elements, spatial allocation and thus direction determination in the evaluation circuit is no longer clearly possible.
  • the invention has for its object to provide a circuit arrangement for monitoring the presence of rail vehicles within certain track sections of the type assumed to be known, with the avoidance of the disadvantages described above, a clear determination of direction and at least a detection of the rail vehicles possible even if an oscillator circuit fails is.
  • the solution to this problem by the invention is characterized in that two galvanically separated clock generators alternately switch the oscillators ineffective, that the oscillators are galvanically separated from one another, that the clock generators are connected to one another via galvanically separated coupling links, are quartz-stabilized and mutually synchronized, that each oscillator is followed by a frequency divider, which is brought into a defined position dynamically, and that the two frequency dividers connected downstream of the oscillators are each assigned their own evaluation circuit.
  • the circuit arrangement according to the invention has the advantage that the use of a separate evaluation circuit means that different oscillator frequencies are no longer required and that mutual interference between the oscillators is avoided in the case of induction loops installed closely next to one another in the track by the fact that the two galvanically separated clocks alternate the oscillators switch ineffective.
  • a mutual electrical influence of the two oscillator circuits is prevented by the fact that the oscillators are electrically isolated from one another and the clock generators are connected to one another via electrically isolated coupling elements.
  • the clock generators are quartz-stabilized and mutually synchronize, with a frequency divider downstream of each oscillator being dynamically brought into a defined position.
  • the correct functioning of the clock generator can be monitored by the two evaluation circuits in that on the one hand the distances between the pulse trains in each evaluation circuit and on the other hand the opposite sense between the individual pulse trains of both evaluation circuits are monitored as a function of the frequency of the clock generator. Interference pulses occurring between the pulse trains acting in the manner of data telegrams are recognized as such because the frequency of the clock generator and thus the pulse train interval times per system are known. Since both systems are completely galvanically isolated from each other, there is no dependency of the systems on each other.
  • the coupling elements are operated with constant current.
  • the function of the clock generator can also be monitored in this way.
  • the coupling elements are designed as optocouplers and the light-emitting diode is connected to a freely programmable output of the corresponding frequency divider.
  • the coupling links are designed as optocouplers, commercially available components can be used.
  • each phototransistor is operated with the voltage of the other sub-arrangement and is connected to the reset input of the corresponding frequency divider. This prevents the entire system from becoming ineffective in the event of a clock failure and a permanent pulse that may be present.
  • a further development according to the invention consists in that the freely selectable output of the frequency divider, which is connected downstream of the clock generator, blocks the oscillator.
  • the invention proposes to provide each evaluation circuit with a microcomputer, as a result of which some of the functions are replaced by appropriate programming of the microcomputer instead of expensive hardware.
  • the illustration shows two oscillators 1a, 1b, each of which comprises an induction loop 2a, 2b laid within a track section.
  • Each oscillator 1a or 1b is followed by a frequency divider 3a, 3b, which changes the frequency of the oscillations of the oscillators 1a or 1b converted into rectangular pulses and passes them on to an amplifier 4a or 4b in order to reliably transmit the pulse trains via commercially available, wire-like cables from to be able to transmit the oscillator side to the evaluation circuit and to be independent of the coupling capacitances of the cables.
  • each evaluation circuit 6a or 6b comprises a signal output 7a, 7b, which is designed as an element galvanically separated from the system, for example as a relay contact or as a DIN interface for data systems.
  • each evaluation circuit 6a or 6b is assigned a voltage source 8a or 8b, which at the same time, via the two-wire line 5a or 5b with the aid of a constant voltage regulator 9a or 9b, the oscillator 1a or 1b, the frequency divider 3a or 3b and the amplifier 4a or 4b supplied with voltage.
  • An operational amplifier 10a or 10b is arranged in each of the lines 5a or 5b leading to the evaluation circuit 6a or 6b and is likewise supplied with voltage by the voltage source 8a or 8b.
  • a clock generator 11a or 11b is additionally supplied with constant voltage via the constant voltage regulator 9a or 9b.
  • the exemplary embodiment in each case is a quartz.
  • a frequency divider 12a or 12b is connected downstream of this clock generator 11a or 11b.
  • These frequency dividers 12a and 12b are connected to one another via coupling elements 13a, 13b, which in the exemplary embodiment are each formed by a light-emitting diode and a photo transistor.
  • the associated frequency divider 12a and 12b is connected to the photo transistor via a dynamic input.
  • the coupling elements 13a, 13b thus result in synchronization with simultaneous electrical isolation of the clock generators 11a and 11b and thus both systems.
  • the oscillators 1a and 1b oscillate with an induction formed by the induction loops 2a and 2b and the corresponding capacitor. These vibrations are converted into rectangular pulses in frequency divider 3a and 3b and their frequency is changed. Due to the frequency of the clock generators 11a and 11b, which mutually synchronize, one light-emitting diode of the coupling elements 13a and 13b is operated alternately in the forward direction. The associated phototransistor switches the applied voltage to the associated frequency divider 12a or 12b. The output Q x of the frequency divider 12a or 12b disables the oscillator 1a or 1b and sets the associated frequency divider 3a or 3b of the useful signal dynamically in a defined position.
  • the clock generators 11a and 11b effect, via the coupling elements 13a and 13b, that only one oscillator circuit emits pulse trains to the associated evaluation circuit 6a or 6b.
  • the light-emitting diodes By operating the light-emitting diodes with constant current, it is possible to monitor the functionality of the clock generators 11a and 11b in the evaluation circuit 6a or 6b by means of the upstream operational amplifier 10a or 10b.
  • This directional Detection is used to switch signals or level crossing protections assigned to the track section on and off.
