Title:
A method for detecting manipulation in a sensor system for locking mechanism, and locking mechanism
Document Type and Number:
Japanese Patent JP6033490
Kind Code:
B2
Abstract:
A sensor system for a locking system of a door includes: an acceleration sensor which is designed to detect movements of the door in at least two dimensions and to record a time-resolved acceleration profile; a magnetic field sensor which is designed to detect a magnetic field in the area of the locking system, to detect changes of the magnetic field and to record a time-resolved magnetic field change profile; and a control device which is coupled to the acceleration sensor and to the magnetic field sensor and which is designed to correlate the acceleration profile to the magnetic field change profile, to compare the profile correlation to a predetermined correlation signature, and to output an alarm signal if the profile correlation matches the correlation signature.
