DEVICE FOR OPENING/CLOSING DOOR BY USING MOBILE TERMINAL

摘要

PURPOSE: A device for opening/closing a door by using a mobile terminal is provided to allow a user to remotely check an opened/closed state of a door and control opening/closing of the door any time and anywhere. CONSTITUTION: A controller(200) controls general operations of a lock unit(107). A channel coding unit(201) performs channel coding and interleaving on a message received from the controller(200), converts it into an analog baseband signal and provides it to a spread modulator(202). The spread modulator(202) spread-modulates the baseband signal and outputs it. A transmission RF unit(203) up-converts the spread-modulated signal into an RF signal and outputs it to an antenna(106) through a duplexer(204). The duplexer(204) transfers a signal transmitted from the transmission RF unit(203) to the antenna(106) and a signal received through the antenna(106) to a receiving RF unit(205). The receiving RF unit(205) down-converts an RF signal received from an adjacent base station into a baseband analog signal, and outputs it. A despread demodulator(206) despread-demodulates a signal received from the receiving RF unit(205) and outputs it. A channel decoding unit(207) restores the despread-demodulated signal into an original information message and provides it to the controller(200). A power supply unit(208) inputs an AC power. An impact sensor(209) senses an impact.
