Abstract

본 발명은 원격제어 기능이 있는 다수의 원격제어 기기들을 하나의 원격제어 송신기로 송신기로 원격제어할 수 있도록 하는 것으로서 종래에는 학습시 원격제어 코드의 구성요소를 펄스 버스트 성분과 펄스 오프 성분으로 인식하는 것으로 학습할 기존의 원격제어 코드와 학습되어 메모리에 압축저장된 신호를 신장하여 송신하는 원격제어 코드간에 시간오차가 발생하였고, 또한 원격제어 코드를 그의 반복패턴에 관계없이 압축하므로 저장할 정보량이 많아 메모리의 용량이 커야 되었다.The present invention allows a plurality of remote control devices having a remote control function to remotely control a transmitter with a single remote control transmitter. In the related art, a component of a remote control code is recognized as a pulse burst component and a pulse off component during learning. There is a time error between the existing remote control code to be learned and the remote control code that extends and transmits the signal that has been learned and compressed and stored in the memory, and also compresses the remote control code irrespective of its repetition pattern. The capacity had to be large.

본 발명은 원격제어 코드의 학습시 하나의 펄스 버스트 신호의 시작시간부터 다음의 펄스 버스트 성분의 시작시간까지를 하나의 펄스의 주기로 인식하는 것을 기본으로 하여 연속되는 펄스 버스트 성분을 읽고, 원격제어 코드의 연속성에 기인하는 반복되는 펄스 버스트 성분 및 펄스 오프 성분의 형태를 인식하여 저장해야 될 정보량을 줄임으로써 오차가 발생됨이 없이 원래의 원격제어 코드를 정확히 발생시켜 제어할 원격제어 기기의 오동작을 방지하고, 메모리의 용량을 줄여 전지의 소모전력을 줄일 수 있다.The present invention reads a continuous pulse burst component on the basis of recognizing the period of one pulse from the start time of one pulse burst signal to the start time of the next pulse burst component when learning the remote control code, and the remote control code By reducing the amount of information to be stored by recognizing the shape of repeated pulse burst component and pulse off component due to the continuity of, it prevents the malfunction of the remote control device to be generated by accurately generating the original remote control code without any error. In addition, the power consumption of the battery can be reduced by reducing the memory capacity.
