Method and apparatus for checking electrical drive mechanisms
First Claim
1. A method for checking a plurality of electrical drive mechanisms, which comprises:
- picking up measured values at a plurality of electrical drive mechanisms and outputting signals describing the measured values;
providing the signals describing the measured values with drive mechanism-specific identifiers;
then carrying the signals without interruption, on-line, to a central or higher-ranking data processing system;
comparing the signals in the data processing system with desired values available in the data processing system; and
indicating an error for a particular drive mechanism at which a signal originated if the signal deviates from its desired value.

Abstract
A method and an apparatus are provided for checking a plurality of electrical drive mechanisms which may, in particular, be drive mechanisms for railroad switches. Measured values are picked up at the same time at the plurality of electrical drive mechanisms, and the signals describing them are provided with a drive mechanism-specific identifier. These thus-identified signals are then carried without interruption, on-line, to a data processing system, where they are compared with desired values that are available there. If a signal deviates from a desired value, an error is indicated for the particular drive mechanism at which the signal originated.

9. An apparatus for checking a plurality of electrical drive mechanisms, comprising:
-
sensors disposed at a plurality of electrical drive mechanisms for picking up measured values and outputting signals describing the measured values; drive mechanism-specific marking devices associated with said sensors for providing the signals with drive mechanism-specific identifiers; a central or higher-ranking data processing system connected on-line to said sensors for receiving the signals without interruption, said data processing system having a comparator for comparing the signals output by said sensors with desired values available in said data processing system; and a display device connected to said data processing system for indicating an error for a particular drive mechanism at which a signal originated if the signal deviates from its desired value. - View Dependent Claims (10, 11, 12, 13, 14, 15)
