| 摘要 |
The invention relates to an opening system for a safety device (3) equipped with locking/unlocking means (11), the opening system having a remote transmitter (2) of coded signals (SC 1 ,...,SC n ) including a selector (T 1 ,...,T n ) of signals to be transmitted. The safety device (3) comprises a learning receiver (6) suitable for learning coded signals (SC 1 ,...,SC n ) transmitted by the remote transmitter (2), a microprocessor (9) operable by the receiver means (6) and including a storage (10) for storing the coded signals (SC 1 ,... ,SC n ) received in input by the receiver (6), as well as an arbitrary sequence (C 1 ,...,C n ) of the coded signals (SC 1 ,...,SC n ) intended to act as opening combination (C) of the safety device (3), and a comparator suitable for activating the operation of the locking/unlocking means (11) for the opening of the safety device (3) upon the reception of a prearranged sequence (SP 1 , ... SP n ) of coded signals (SC 1 ,...,SC n ) emitted by the remote transmitter and coinciding with the opening combination (C).
