1. A transmission and reception system for controlling a locking/unlocking operation of an electronic lock mounted in a door, comprising:
- a transmission unit for transmitting a control signal having a predetermined frequency for controlling a locking/unlocking operation of said electronic lock;
a reception unit for receiving the control signal and effecting driving control of said electronic lock in response to the control signal, wherein said reception unit includes a carrier detection circuit for detecting a frequency of the control signal and a mechanism unit for performing the locking/unlocking operation; and
a power supply unit arranged in the door for supplying power to said carrier detection circuit and including a switch for selectively supplying power to said mechanism unit, wherein said power supply unit supplies power only to said carrier detection circuit when the control signal is not received and supplies power to said mechanism unit when the control signal is received.
