<p>The locking system includes a blocking and electronic releasing device by means of different codes for each one of the keys, it also being possible to modify the memory of the control circuit by means of an operating key to refuse access to a lost key, also allowing access to other new copies of the key. This electronic blocking is done by means of an independent pin of the locking pistons of the mechanical part of the cylinder, the latter being inside as well as outside the same. The key (4) communicates to the cylinder (1) its code by means of an electric contact (9) through which the energy required for its operation will be supplied to it. The transmission of data of the key to the cylinder is done by the electric contact itself (9). A rotary-type electric motor (10) acts on a blocking pin (6) by means of an eccentric (11) and connecting rod (12.) The control circuit of the cylinder (1) has a memory in which the codes of the keys (4) that have access to the lock appear. The control circuit will launch its reading process of the code of the key to allow or refuse retraction of the blocking pin (6.) <IMAGE></p> |
