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 having an antenna for contactlessly receiving an access authorization signal from a separate transponder, wherein an excitation signal for the transponder is emitted by the antenna only in an active state of the antenna, wherein the locking arrangement has a voltmeter which is used to capture an electrical voltage dropped across the antenna or a voltage change in the passive state of the antenna, wherein the antenna changes from the passive state to the active state if a voltage drop is present across the antenna in the passive state. A corresponding method is also described.
