Definitions

  • the invention relates to a device for detecting the positions of pivotable parts of a switch, e.g. Tongue rails, with at least one sensor, and a method for Signal evaluation of sensors to determine the position of pivotable parts of a switch, by means of this device.
  • DE 35 11 891 A1 describes a device consisting of a electric motor driven single turnout drive, a definable Adjustable and, if applicable, also a definable one Monitoring slide and a sensor arrangement for detecting the Slider end positions and their safety status have become known. With the help of the sensors integrated in the devices monitoring of the end positions and the closed position of the actuating and, if necessary, monitoring slide recognized. The test results are then sent to a tax and Monitoring logic or a controlling signal box passed on, whereby the passability of the switch is determined. A distance measurement the tongue rail to the stock rail does not take place.
  • DE 26 36 359 A1 is a monitoring device for the End positions of swiveling rails of railway switches have become known, with inductive rail switches at certain control points are provided, which of the pivotable Brushed ferromagnetic counterparts arranged over the rail become. Due to the inductively triggered switch triggering be determined whether the pivotable rail is in its end position located.
  • This procedure essentially aims to be premature Wear in the area of the tongue rail through a Detect sensor so that the smallest determined when driving Value of the distance between tongue rail and stock rail saved distance values and limit values are defined and were compared and when exceeded a maintenance signal is triggered after a certain limit value.
  • Possible proximity sensors are inductive or capacitive analog sensors provided.
  • inductive proximity switches are very reliable and wear-free switching elements, however, they can not used to determine the exact position of the moving To determine parts of a switch constantly, but only used to signal whether the switch tongue is the respective one Has reached the end position or not. Because inductive Proximity switches are used in resonant circuits the accuracy of the measurements of the resonant circuit quality, which is strong dependent on external influences and the accuracy of the components is. Complex measures are therefore necessary in order to To increase the redundancy and accuracy of these measuring devices.

  • the Tongue rail position not linearly dependent on the sensor signal is the distance evaluation in a particularly advantageous manner executed so that it interacts with a characteristic curve query. Thanks to such a characteristic curve query, an exact The tongue rail position can also be determined if the measurement signals are not based on a linear distance law.
  • a particularly preferred development of the measuring device is that the output of at least one other sensor connected to the function control for measuring the idle signal is.
  • a further sensor which is either specially calibrated or with the actual one Distance sensor is identical, is used the accuracy of the measurement of the idle signal and thus the Functional control reliability increased.
  • a switch is a particularly useful one Formed such that at least two distance sensors each at the loading and unloading position of the swiveling parts are arranged on the track. Because now several distance sensors are arranged accordingly, in addition to the functional check in the undamped state also another function check take place in the damped end position. The stake at least two installed in different locations Distance sensors also create the possibility of reliability the function check and the accuracy of the distance measurement with the help of a measured value comparison and / or a Increase averaging. Furthermore, such serves Training to do this, the tongue rails over the entire length of the switch to observe changes in shape, taking the measurements can also take place during the crossing. In this way can determine the overall condition of the switch position and long-term Changes are predetermined.
  • the characteristic curve is designed such that that they each have tolerance ranges for permissible functional areas for the placement and storage of the pivotable parts and that a functional control for the investment and Storage position is done.
  • the idle signal as a calibration variable for the characteristic with Characteristic curve interacts.
  • the idle signal will shift the characteristics themselves that the value of the rest signal equal to the function value at the storage position is a family of curves.
  • Another disturbance in the form of line losses e.g. Prevent voltage drops at the line resistances, are the sensor outputs in an advantageous manner as current outputs educated.
  • the sensor outputs as current outputs are executed, the sensor signals are in the form of light streams that can be further processed.
  • the procedure for evaluating the signals from the sensors essentially consists in that the sensor signals in a characteristic curve calculator the positions are evaluated as functions of the signal values are determined, the signals with the sensor rest signals be compared and the functionality of the sensors is determined and, if applicable, signal values which are outside of tolerance windows specified in the characteristic curves, be used for error messages, the characteristic by comparison with the quiescent current signals within a permissible Tolerance is adapted to the ambient conditions and short-term error messages can be suppressed.
  • a particularly preferred method step in addition monitors the operational readiness of the point machine, whereby an even higher reliability of the point setting device can be achieved.
  • monitors the point machine it is ensured that malfunctions that affect the point machine are due, and not due to age-related wear or other environmental disorders of the tongue splint originate, be recognized in time. So it succeeds Main sources of error, which lead to decommissioning and repair of the rail switch lead constantly and separately from each other to monitor.
  • Another advantageous process step to ensure safe Monitor the function of the closures and the narrowest passage check is that the signals come from different Measurement levels are compared with each other.
