Abstract
본원 발명은 입력 스캔타임(scan time)보다 빠르게 변화되는 입력의 변화를 검출할 수 있는 범용콘트롤러의 입력장치에 관한 것으로서, 입력전압과 제어전압의 레벨이 다른 경우에 전기적으로 회로를 비접속하는 절연회로와, 상기 절연회로의 출력신호에 포함된 잡음을 제거하는 저주파통과필터와, 상기 저주파통과필터의 출력신호를 입력으로 하여 유효신호가 시작되는 부분을 감지하는 에지검출회로와, 중앙처리장치로부터 신호를 받아 제어신호를 발생하는 게이트선택회로와, 상기 게이트 선택회로의 제어신호에 따라 상기 에지검출회로의 출력 신호를 데이타버스로 출력하는 제1게이트회로와, 상기 게이트선택회로의 제어신호에 따라 상기 저주파통과필터의 출력신호를 데이타버스로 출력하는 제2게이트회로와, 상기 에지검출회로에서 에지가 검출된 후 상기 에지의 유지값을 소거하도록 상기 게이트선택회로의 제어신호에 따라 에지소거신호를 출력하는 소거회로로 구성되어 입력신호의 에지 및 레벨을 검출함으로서 입력스캔타임 사이에 입력되는 유효신호를 처리할 수 있는 것을 특징으로 한다.The present invention relates to an input device of a general-purpose controller that can detect a change in an input that changes faster than an input scan time. The present invention relates to an insulation that electrically disconnects a circuit when the input voltage and the control voltage are different. A low pass filter for removing noise included in an output signal of the insulation circuit, an edge detection circuit for detecting a portion at which an effective signal starts by inputting an output signal of the low pass filter, and a central processing unit from the central processing unit. A gate selection circuit for receiving a signal and generating a control signal, a first gate circuit for outputting an output signal of the edge detection circuit to a data bus according to a control signal of the gate selection circuit, and a control signal of the gate selection circuit A second gate circuit for outputting an output signal of the low pass filter to a data bus, and edge detection in the edge detection circuit; And an erase circuit for outputting an edge erase signal in accordance with a control signal of the gate selection circuit to erase the sustain value of the edge, thereby processing a valid signal input between input scan times by detecting edges and levels of the input signal. It can be characterized by.
