1. A REMOTE CONTROL SYSTEM FOR ACCESS MANAGEMENT AND Control, particularly applicable to remote opening and closing of doors of garages, dwellings and automobiles, which has one or more controls (1) that communicate with one or more receiving hosts (2, 3, 4) that govern the opening/closing of said doors or accesses;

  • characterised in that each of said controls (1) has a single pushbutton (5) that acts in such a way that depending on a number and/or duration of the presses made on said pushbutton (5) and/or a proximity of the control (1) to hosts (2, 3, 4), the control (1) can control and be controlled by any number of receiving hosts (2, 3, 4), according to pre-established modes;

    being a communication between each control (1) and the receiver host (2, 3, 4) a bi-directional data communication that includes a secret coding, (stored in both the remote controls and in the receiving hosts, by means of an algorithm for codifying which allows useful information for diverse functions to be transmitted, so that authorisation for use in the system and the inviolability of the aforementioned communication are assured by means of said algorithm, which is a referential positioning dynamic algorithm, called rpda, specially developed for this system, which allows information packages of any size to be protected and which consists of a pre-coded preamble that heads all communication messages and requires a satisfactory reply by the communicating element at the end of the entire message flow.
