Method for determining the state of access control devices and sales or payment machines of an access control system
First Claim
1. A method of determining a state of access control devices and sales or payment machines of an access control system, the method comprising:
- detecting, permanently or in predetermined time intervals, a sound profile in an audible or an ultrasonic range emitted during operation by a component or a component group of an access control device or a sales or payment machine of an access control system by at least one microphone and on a basis of a recorded sound profile,creating an acoustic identification signature in a server or a central computer, which identification signature is based on a frequency spectrum of the recorded sound profile and/or a temporal change thereof,assigning the acoustic identification signature to a component or a component group and comparing with an acoustic reference identification signature which is stored in the server and assigned to the component or component group,in an event of 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, detecting increased wear of the component or the component group, andin an event of detection of the deviation of the detected acoustic identification signature from the acoustic reference identification signature stored in the server, which deviation exceeds a second threshold value, which is higher than the first threshold value, detecting a defect of the component or the component group.

Abstract
A method for determining the state of access control devices and sales or payment machines of an access control system by detecting sound profiles emitted during operation by a component or component group by at least one microphone. Based upon the recorded sound profile, an acoustic identification signature is created in a server or a central computer, which identification signature is based on the frequency spectrum of the recorded sound profile and/or the temporal change thereof. The acoustic identification signature is compared with a reference identification signature(s) stored in the server and assigned to a component or a component group. In the event of the detecting an acoustic identification signature which exceeds a predetermined first threshold value, increased wear of the component or the component group is detected, while if the deviation exceeds a second threshold value, a defect of the component or the component group is defected.

4. A method of determining a state of access control devices and sales or payment machines of an access control system, the method comprising:
-
detecting, permanently or in predetermined time intervals, a sound profile in an audible or an ultrasonic range emitted during operation by a component or a component group of an access control device or a sales or payment machine of an access control system by at least one microphone and on a basis of a recorded sound profile, creating an acoustic identification signature in a server or a central computer, which identification signature is based on a frequency spectrum of the recorded sound profile and/or a temporal change thereof, assigning the acoustic identification signature to a component or a component group and comparing with an acoustic reference identification signature which is stored in the server and assigned to the component or component group, in an event of 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, detecting increased wear of the component or the component group, in an event of detection of the deviation of the detected acoustic identification signature from the acoustic reference identification signature stored in the server, which deviation exceeds a second threshold value, which is higher than the first threshold value, detecting a defect of the component or the component group, storing identification signatures, in addition to an acoustic reference identification signature for a component or a component group, in the server which, in each case, correspond to an actual defect of a component or a component group, an identification signature not corresponding to the reference identification signature can, in a case of adequate matching with an identification signature corresponding to an actual defect of a component group, be assigned to the respective defect of a component of a component group directly, and in a case of detected identification signatures, which neither corresponds to the reference identification signature nor to an identification signature assigned to a defect of a component or a component group, storing these identification signatures in the server as new identification signatures, which correspond to a not yet classified or categorized defect, and classification or categorization the detected identification signatures when the defect is identified.

8. A method of determining a state of access control devices and sales or payment machines of an access control system, the method comprising:
-
detecting, permanently or in predetermined time intervals, a sound profile in an audible or an ultrasonic range emitted during operation by a component or a component group of an access control device or a sales or payment machine of an access control system by at least one microphone and on a basis of a recorded sound profile, creating an acoustic identification signature in a server or a central computer, which identification signature is based on a frequency spectrum of the recorded sound profile and/or a temporal change thereof, assigning the acoustic identification signature to a component or a component group and comparing with an acoustic reference identification signature which is stored in the server and assigned to the component or component group, in an event of 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, detecting increased wear of the component or the component group, in an event of detection of the deviation of the detected acoustic identification signature from the acoustic reference identification signature stored in the server, which deviation exceeds a second threshold value, which is higher than the first threshold value, detecting a defect of the component or the component group, and assigning a detected identification signature to a component or component group on a basis of a known precise sequence of the individual operations during the operation of an access control device or the sales or payment machine of the access control system, uniquely assigning the detected identification signature to one operation and therefore one component or one component group, and detecting the start of operation of the access control device or the sales or payment machine on a basis of the signals delivered by the at least one microphone.
