Title: LOCKING ARRANGEMENT, IN PARTICULAR DOOR LOCK ARRANGEMENT FOR A SWITCHGEAR CABINET, AND A CORRESPONDING METHOD
Abstract:
The invention relates to a locking arrangement, in particular a door lock arrangement for a switchgear cabinet, which has a system for verifying a locking authorization, wherein the system has a door lock (100) having an antenna (104) for contactlessly receiving an access authorization signal from a separate transponder (201), wherein an excitation signal for the transponder (201) is emitted by the antenna (104) only in an active state of the antenna (104), characterized in that the locking arrangement has a voltmeter (105) which is used to capture an electrical voltage dropped across the antenna (104) or a voltage change in the passive state of the antenna (104), wherein the antenna (104) changes from the passive state to the active state if a voltage drop is present across the antenna (104) in the passive state. A corresponding method is also described.
