Method and arrangement for fault detection in a switch system

Abstract

For fault detection in a switch system including multiple switches, for a respective switch its operating data are acquired and transmitted to a central control. For a respective first switch of the switch system, a deviation of an operating behavior of the first switch from a set behavior is determined by the central control on the basis of its operating data. If there is a deviation, operating data of the first switch are compared with operating data of other, second switches of the switch system and, depending on that, a second switch with similar operating data is selected.

1 . A method for fault detection in a switch system that is distributed over at least one track route and comprises multiple switches, the method comprising:
 acquiring operating data of the switch concerned for the switches of the switch system, and transmitting the operating data to a central control; and   b) for a respective first switch of the switch system,
 determining a deviation of an operating behavior of the first switch from a set behavior by the central control on a basis of the operating data of the first switch, 
 if there is a deviation, comparing the operating data of the first switch with operating data of other, second switches of the switch system, 
 depending on the results of the comparison, selecting a second switch with similar operating data, 
 on the basis of the operating data of the selected second switch, deriving a fault indication for the first switch, and 
 outputting the fault indication for the first switch. 
   
     
     
         2 . The method as claimed in  claim 1 , wherein the operating data acquired for a respective switch are transmitted to the central control by a transmitting device assigned to the respective switch. 
     
     
         3 . The method as claimed in  claim 1 , wherein an indication of a fault cause is sought in the operating data of the selected second switch and, if such an indication is found, the indication found is output as a fault indication for the first switch. 
     
     
         4 . The method as claimed in  claim 1 , wherein an indication of a fault that has occurred is sought in the operating data of the selected second switch and, if such indication is found, the indication found is output as a fault forecast for the first switch. 
     
     
         5 . The method as claimed in  claim 1  wherein the operating data of a respective switch comprise a variation over time of a current consumption and/or a variation over time of a power consumption of a switch operating mechanism of the respective switch. 
     
     
         6 . The method as claimed in  claim 1 , wherein the operating behavior and/or the set behavior of the respective first switch is simulated by means of a physical simulation model of the first switch on the basis of the operating data of the first switch. 
     
     
         7 . The method as claimed in  claim 1 , wherein multiple second switches of which the operating data are similar to the operating data of the first switch are selected, and the operating data of the selected second switches are combined to derive the fault indication. 
     
     
         8 . The method as claimed in  claim 1 , wherein, when comparing operating data of a respective first switch with operating data of a respective second switch, a distance measure for a distance between the respectively compared operating data is determined and/or operating data patterns are determined by a pattern recognition method and compared. 
     
     
         9 . The method as claimed in  claim 1 , wherein a knowledge graph of which the nodes are respectively assigned to a switch of the switch system is managed by the central control, and the operating data of a respective switch are stored in assignment to a node assigned to this switch. 
     
     
         10 . The method as claimed in  claim 1 , wherein virtual operating data for a multiplicity of virtual switches are generated by means of a physical simulation model, and the virtual operating data are used as operating data of the second switches. 
     
     
         11 . The method as claimed in  claim 10 , wherein a number of virtual switches is determined depending on a number and/or an age of the switches of the switch system. 
     
     
         12 . An arrangement for fault detection in a switch system that is distributed over at least one track route, designed for carrying out a method as claimed in  claim 1 . 
     
     
         13 . A computer program product, comprising a computer readable hardware storage device having computer readable program code stored therein, said program code executable by a processor of a computer system to implement a method as claimed in  claim 1 . 
     
     
         14 . A computer-readable storage medium with a computer product as claimed in  claim 13 .
