Abstract
본 발명은 비동기 통신제어장치에 관한 것으로, 특히 복수개의 기기가 접속되어 있는 AV시스템에 공통 직렬 통신방식(Common Serial Communication Method)를 사용하여 각 기기에 동일 우선권을 부여함으로써 한기기의 통신라인의 독점을 피하고, 통신의 우선 선점에 따른 각 기지의 동작명령이나 상태를 파악하여 원하는 데이타를 원하는 기기에 전송하도록 한 AV시스템의 비동기 통신제어장치에 관한 것이다. 상기와 같은 목적을 달성하기 위한 본 발명의 AV시스템의 비동기 통신제어장치는 AV 시스템이나 HA(Home Automation)시스템에 있어어, 타기기의 제어신호 또는 본 기기의 제어신호와 본 기기의 제어신호를 비교, 합성하여 제1충돌신호를 검출하는 제1충돌검출부와, 상기 제1충돌검출부의 제1충돌신호를 받아 1/2 Tm윈도우신호를 발생하는 1/2윈도우신호발생부와, 상기 제1충돌검출부의 제1충돌신호를 받아 시간축 지연에 대한 보상을 하는 지연보상수단부와, 상기 지연보상수단부의 보상신호와 상기 1/2윈도우신호발생부의 1/2Tm윈도우신호를 비교, 합성하여 제1충돌보상신호를 출력하는 제1충돌보상수단부와, 상기 제1 충돌보상수단부의 제1충돌보상신호와 상기 1/2윈도우신호 발생부의 1/2Tm윈도우신호를 비교, 합성하여, 제2충돌신호를 검출하는 제2충돌검출부와, 상기 제2충돌검출부의 제2충돌신호를 윈도우(window)신호로 바꾸어주는 윈도우신호발생부와, 상기 윈도우신호발생부의 윈도우신호와 본기기의 제어신호를 비교, 합성하여 전송데이타 또는 무신호를 발생하는 송신판단부와, 상기 송신판단부에서 발생하는 신호를 송신하고, 타기기의 제어신호를 수신하거나, 본기기의 제어신호를 수신하여 본기기의 마이컴에 전달함과 동시에 상기 제1충돌검출부로 전달하는 송, 수신 판단부로 이루어짐을 특징으로 한다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an asynchronous communication control device, and more particularly, to monopolize a communication line of a device by giving the same priority to each device using a common serial communication method to an AV system to which a plurality of devices are connected. The present invention relates to an asynchronous communication control apparatus of an AV system which avoids the operation of each known base and the state of communication according to the preemption of communication, and transmits the desired data to a desired device. Asynchronous communication control apparatus of the AV system of the present invention for achieving the above object is in the AV system or HA (Home Automation) system, the control signal of the other device or the control signal of this unit and the control signal of the unit A first collision detection unit for comparing and synthesizing the first collision signal, a half window signal generator for generating a 1/2 Tm window signal in response to the first collision signal of the first collision detection unit, and the first collision signal Comparing and synthesizing the delay compensation means unit for compensating for the time axis delay by receiving the first collision signal of the collision detection unit, the compensation signal of the delay compensation unit and the 1 / 2Tm window signal of the 1/2 window signal generation unit A second collision signal by comparing and synthesizing a first collision compensation means unit for outputting a collision compensation signal, a first collision compensation signal of the first collision compensation means unit, and a 1/2 Tm window signal of the half window signal generation unit; A second collision detection unit for detecting Comparing and synthesizing the window signal generation unit for converting the second collision signal of the second collision detection unit to a window signal, the window signal of the window signal generation unit and the control signal of the device to generate transmission data or no signal A transmission determining unit and a signal generated by the transmission determining unit, receiving a control signal of another device, or receiving a control signal of the main unit and transmitting the signal to the microcomputer of the main unit, to the first collision detection unit. It is characterized by consisting of a transmission and reception determining unit for transmitting.
