Abstract

본 발명은 유선리모콘의 비동기식 송신장치 및 그 방법에 관한 것으로 종래에는 2개 이상의 유선리모콘에서 동시에 직렬데이타가 출력되었을 경우 주장치가 인식하지 못하는 결과치를 이루게 되어 아무런 동작을 하지 않거나 오동작을 하는 문제점이 있어 본 발명은 이러한 점을 감안하여 출력선의 상태를 감지하고 직렬데이타의 송신여부를 판단하여 각 유선리모콘에서 출력되는 직렬데이타가 충돌하는 것을 방지하여 먼저 출력된 직렬데이타를 주장치로 보내도록 하는 기능을 유선리모콘에 네장된 범용원칩마이컴에 추가하여 2개 이상의 유선리모콘이 동시에 동작되어도 유선리모콘에서 출력되는 직렬데이타를 정확하게 송신할 수 있도록 하여 사용할 수 있다.The present invention relates to an asynchronous transmission device and a method of a wired remote control, and conventionally, when serial data is output from two or more wired remote controllers at the same time, the main device achieves a result that the main device does not recognize. In view of the above, the present invention detects the state of the output line and judges whether or not to transmit serial data, thereby preventing the serial data output from each wired remote controller from colliding with each other. In addition to the universal one-chip microcomputer installed in the remote controller, even if two or more wired remote controllers operate simultaneously, the serial data output from the wired remote controller can be accurately transmitted.
