<p>The invention relates to an operating method and an electronic-mechanical installation for locking/unlocking (safety lock), actuated by infrared remote control, with a code emission, reception and electronic code processing, meant for providing door locking/unlocking and eliminating the possibility of unlocking or damaging by forcing the safety lock mechanically by unauthorized persons. According to the invention, the method uses, for locking/unlocking the safety lock, the infrared generation and emission-reception of a code consisting of a quasi-infinite number of codes, which may be used, and the comparison of the received code with the code recorded in the receiver memory. According to the invention, the installation consists of a remote control generating the code by means of a micro-controller (u1-E3), code emitted in infrared, and a safety lock, respectively, said safety lock comprising a code receiver in combination with a micro-controller (u1-R3) and, besides an usual mechanical part, it also comprises a cam (C) for automatically blocking the safety lock, in case of unauthorized forcing.</p> |
