Abstract

In the context of the method for determining the state of access control devices and sales or payment machines of an access control system, the sound profile in the audible or ultrasonic range emitted during operation by a component or component group of an access control device or a sales or payment machine of an access control system is detected permanently or in predetermined time intervals by at least one microphone, wherein on the basis of the recorded sound profile, an acoustic identification signature is created in a server or central computer, which identification signature is based on the frequency spectrum of the recorded sound profile and/or the temporal change thereof, wherein the acoustic identification signature is compared with an acoustic reference identification signature which is stored in the server and assigned to this component or component group, and wherein in the event of the detection of a deviation of the detected acoustic identification signature from the acoustic reference identification signature stored in the server, which deviation exceeds a predetermined first threshold value, increased wear of the component or the component group is detected, wherein if the deviation of the detected acoustic identification signature from the acoustic reference identification signature stored in the server exceeds a second threshold value, a defect of the component or the component group is detected.
