发明名称 Process and device for controlling the closure of locks
摘要 A process reliably detects the change of the locking state of at least one lock with a logic with memory and display attached to a key. The process includes determining a rotation of the key associated with the lock within the lock, detecting a single or multiple rotation in unlocking or locking direction of the lock and simultaneously determining whether the detected rotation occurs in unlocking or locking direction of the lock. A signal is generated that indicates the unlocking or locking of the lock. This signal is stored in the memory of the logic, and the signal is displayed. A device for implementing the process includes one or several markers mounted near the lock, one or several sensors non-rotatably connected with the key for detecting these markers, a logic attachable to the key with a memory in which data can be stored whereby the logic can process the signals received from the sensors, and a display for displaying the locking state.
