Abstract

본 발명의 원격 제어기기의 반송파 주파수 변경방법 및 변경장치는, 리모콘에서 적외선으로 송신되는 동작 명령에 따라 원격제어되는 각종 원격 제어기기에서 동작명령을 변조하는 반송파의 주파수를 변결할 수 있도록 하는 것이다. 송신부에서 송신되는 약 940~950mm의 파장을 가지는 적외선과 형광등에서 출력되는 약 900mm의 파장을 가지는 광이 상호간에 간섭을 발생하고, 이로 인하여 송신부에서 송신된 적외선이 수신부에 원활하게 수신되지 않으며, 기기가 오동작을 하게 되는 것을 해결하기 위한 본 발명은, 적외선 수신부(24)가 수신하는 신호가 잡음신호인지를 마이콤(21)이 판별하고, 설정된 시간이상으로 계속 잡음신호가 수신될 경우에 반송파 주파수 선택부(25)를 제어하여 적외선 수신부(24)가 수신할 적외선의 반송파 주파수를 변경하게 함과 아울러 표시부(26)에 반송파 주파수의 변경을 표시하며, 송신부의 반송파 주파수의 변경 요청에 따라 사용자가 반송파 주파수 선택부(15)를 조작하게 하고, 반송파 주파수 선택부(15)가 선택한 반송파의 주파수로 동작 명령을 변조하여 송신하게 함으로서 송신부에서 송신되는 동작명령이 원활하게 수신부로 수신되고, 이로 인하여 오동작없이 정확히 동작할 수 있게 된다.The method and apparatus for changing a carrier frequency of a remote controller according to the present invention are to change the frequency of a carrier modulating an operation command in various remote controllers remotely controlled according to an operation command transmitted from the remote controller to the infrared. Infrared rays having a wavelength of about 940 to 950 mm transmitted from the transmitter and light having a wavelength of about 900 mm output from the fluorescent lamp interfere with each other, and thus, infrared rays transmitted from the transmitter are not smoothly received at the receiver. According to an embodiment of the present invention, the microcomputer 21 determines whether a signal received by the infrared receiver 24 is a noise signal, and selects a carrier frequency when the noise signal is continuously received for more than a predetermined time. The control unit 25 controls the infrared receiver 24 to change the carrier frequency of the infrared rays to be received, and displays the change in the carrier frequency on the display unit 26, and the user changes the carrier frequency in response to a request for changing the carrier frequency of the transmitter. The frequency selector 15 is operated, and the carrier frequency selector 15 modulates the operation command by the frequency of the selected carrier and transmits. That is, by the operation instruction it is smoothly transmitted from the transmitter received by the receiving unit, which results it is possible to correctly operate without malfunction.
