Definitions

  • pairs of values are then formed on the one hand from the respective positions during load switching, which can be graduated practically arbitrarily, that is, on the one hand, and on the other hand, the torque values determined at these positions.
  • These determined pairs of values are compared with the previously saved, member-specific pairs of values, the target values and limit values. Depending on the result of this comparison, certain status messages are output. If the comparison shows a correspondence between the corresponding actual and target value pairs, an "ok" message is generated, which, however, can also be suppressed.
  • the further inventive method described in claim 2 includes the same first process steps: Again, the rms values of current and voltage determined, and at the same time a position is determined, as has already been explained.
  • This method assigns the corresponding torques over time, which in turn corresponds to the angle of rotation traveled during load switching.
  • An actual torque value is generated at regular short time intervals, for example every 20 ms, and stored in a ring buffer.
  • This is followed by synchronization using a synchronizing pulse.
  • a synchronizing pulse is generated at the start of a particularly characteristic functional sequence during the switching sequence at a time t syn .
  • the triggering of the energy accumulator which in turn triggers the sudden actuation of the diverter switch, can be used particularly advantageously for generating this synchronizing pulse.
  • Measured value recording is thus carried out according to the principle of a transient recorder known per se. The advantages of this method will be explained in more detail below with reference to FIG. 2.
  • the torque curve synchronized in this way is then broken down into characteristic parts, so-called windows.
  • Each window corresponds to a characteristic part of the switching sequence that is taking place.
  • Such windows can include, for example, the period of actuation of the preselector, the fine selector or the diverter switch.
  • Each window is limited by two characteristic points in time that determine the start and end of the window: t 0 - t 1 ..., ..., t syn - t n .
  • Each of these windows is compared with previously stored characteristic target values. This selective comparison method not only detects a deviation of the actual values from the target values of the torque and thus an error, but also an error that occurs can be assigned to a specific module that is causing it.
  • Characteristic measured values are recorded during the switchover process, here current and voltage, from which information about the prevailing active current and thus the current torque is generated. Then there is a comparison with target values and evaluation of the comparison. As a result, information or messages are generated that can express different priorities. In the event of significant deviations from the respective setpoint, it may be necessary to switch off immediately, for example if the torque during the load changeover exceeds an absolute (extreme) setpoint that is still permissible. In the event of deviations in a non-critical area that do not immediately question safety, information can be output that recommend early maintenance, indicate an expected end of life or make other trend statements.
