FIELD: engineering of electric locks with electronic devices, possible use for locking an apartment, office, safe, etc.
SUBSTANCE: electronic lock device contains key and lock. Electronic key contains buttons "open", "close", "open" and "closed" indicators, transmitter-receiver, microcontroller. Electronic lock contains electro-mechanical executive device, microcontroller, transmitter-receiver. Transmitter contains phase manipulator, high frequency generator, first mixer, first heterodyne, first intermediate frequency amplifier, power amplifier and transmitting antenna. Receiver contains receiving antenna, high frequency amplifier, second mixer, second heterodyne, second intermediate frequency amplifier, multiplexer, band filter and phase detector.
EFFECT: increased reliability of duplex radio connection between key and lock by using complex signals with phase manipulation.
