CODE LOCK FOR CONTAINERS Russian patent published in 2004 - IPC

FIELD: applicable for protection of containers against an unauthorized access of strangers and their location. SUBSTANCE: the code lock has a power supply source on the container, remote-controlled switch with two opposite phase windings, code device, ferreed contacts consisting of the "authorize" and "inhibit" groups, electromechanical locking device consisting of actuating units kinematically linked with the mechanical lock, relay winding and make contacts of the alarm system, duplex radio communication transmitter consisting of a master oscillator, modulation code generator, phase manipulator and a power amplifier. In addition the lock has a receiver of GPS signals, consisting of receiving antenna, high-frequency amplifier, detector and a phase detector. At the control station the lock has a transceiving antenna, duplex, recording unit, receiver of duplex radio communication consisting of a high-frequency amplifier, detector and a phase detector, microprocessor, transmitter of duplex radio communication having a master oscillator, phase manipulator and a power amplifier, receiver of GPS signals containing a receiving antenna, high-frequency amplifier, detector and a phase detector. The detector has a phase doubler, spectrum width meters, comparison unit, threshold unit and a key. EFFECT: expanded functional potentialities of the lock due to precise location of the container subjected to an unauthorized opening by evildoers. 3 dwg
