Abstract (en)
[origin: WO0009836A1] The invention concerns a device for controlling access between an electronic key (1) and lock (2). The key (1) comprises an electric power source (10), a key computing unit (11), a module for transmitting and-receiving signals controlling access to the key (12), and the lock (2) a central lock processing unit (21) and a lock transmission-reception module (22). The key (1) further comprises a module (13) for generating a power signal, a key transfer circuit (14), and the lock (2) comprises a lock transfer circuit (24), said circuits (14 and 24) enabling the two-way transfer of signals controlling access to key and lock and one-way transfer signal of electric power carried by the power signal between the key (1) and the lock (2). The invention is useful for controlling special high security access.
