Dynamically controlled electronic locking system and control system fitted with such a locking system

Dynamically controlled electronic locking system including means (10) for entering data, an electromagnetic actuation device (26) for controlling a bolt (28) and an electronic circuit (12), characterised in that said circuit includes:

• a first memory (80) for storing a reference value (REF),
• a second memory (82) for storing a current value (CRT),
• a processing unit including a first register (30) for applying a function to the reference value (REF), a second register (36) for processing the current value (CRT), a third register (38) for processing an entry value (INT), means for transferring the reference value (REF) and the current value (CRT) from its memory into its respective register and conversely, and logic means (32, 40, 42, 90) for:
• processing the reference value (REF) contained in the first register to define a new reference value replacing the former value (REF) in the first register (30),
• combining the current value (CRT) contained in the second register (36) and the entry value (INT) contained in the third register (38), to define a new current value contained in the second register (36),
• comparing the content of the first (30) and second (36) registers and,
• in the event of a match only, sending an instruction to the electromagnetic actuation device (26) to control the bolt (28), and replacing in the first memory (80) the reference value contained therein by the new reference value contained in the first register (30) and replacing in the second memory (82) the current value contained therein by the new current value contained in the second register (36).
