a security architecture for entriegelungssystem activities in emergency and authorised persons

摘要

A security structure-opening assembly (12) for use in unlocking a locked structure (24) comprising: a radio frequency receiver (16) formed to detect radio frequency signals on a radio frequency; an actuator (20) coupled to the receiver (16) and formed for coupling to one of a security structure lock assembly (25) and an unlocking mechanism (22A) for a security structure lock assembly (25) at a position by-passing any authorized user input device (23); the receiver (16) being responsive to detected signals to actuate the actuator (20) and produce unlocking of the lock assembly (25). At progressively higher levels of security, the radio signal is analyzed by a private line detector circuit (30), a digital burst detector circuit (31) and a decoder circuit (32). A method for providing a security structure-opening system (12) for a locked structure (24) having an authorized user input device (23) comprising the steps of: coupling a radio frequency receiver assembly (16) to a lock assembly (25) for the locked structure at a position by-passing the authorized user input device (23), the receiver assembly (16) being formed to detect the presence of signals on a radio frequency and formed to be responsive to a detected signal to unlock the lock assembly (25); and unlocking the lock assembly (25) by transmitting a signal on a radio frequency to the receiver (16). At progressively higher levels of security, the process includes the steps of analyzing the radio signal by a private line detector circuit (30), by a digital burst detector circuit (31) and by a decoder circuit (32).
