본 고안은 전장품제어마이컴의 초기신호지연장치에 관한 것으로서, 더욱 상세히는 출력표시를 가지는 전장품의 초기신호지연장치에 관한 것이다.The present invention relates to an initial signal delay device for an electronic device control microcomputer, and more particularly, to an initial signal delay device for an electronic device having an output display.

자동차에서 사용되는 다양한 전장품의 경우 운전자의 조작패널상에 이러한 전장품의 상태를 표시하는 시그널장치가 되어 있다.In the case of various electronic devices used in automobiles, there is a signal device that displays the state of such electronic devices on the driver's operation panel.

제1도에 자동차용 전장품의 출력표시제어가 예시적으로 도시된다. 마이컴(1)에 의하여 제어되는 전장품은 출력단표시기(2:도면에서의 발광다이오우드를 도시함)를 제어하는 출력단표시제어IC(3)를 구동함으로서, 전장품의 출력표시의 제어가 이루어지는 구성을 가진다.In Fig. 1, the output display control of the automotive electronics is exemplarily shown. The electrical equipment controlled by the microcomputer 1 has a structure in which the output display control of the electrical equipment is controlled by driving the output stage display control IC 3 that controls the output stage display device 2 (showing the light emitting diode in the drawing).

그러나, 상기한 같이 일반적으로 마이컴에 의하여 제어되는 이러한 전장품은 초기에 시동스위치를 ON함에 의하여 전원이 연결되면 전장품의 현재 상태와는 무관하게 출력표시장치에 전원이 인가되어 현재의 상태와는 상이한 지시(예를 들면 ON신호가 들어왔다가 OFF되는 것 등)를 하게 됨으로 운전자의 혼란을 야기시키는 문제점을 가진다.However, as described above, such electric appliances, which are generally controlled by the microcomputer, are initially powered on by turning on the start switch, so that the power is supplied to the output display device regardless of the current state of the electric appliances, thereby indicating a different indication from the current state. (For example, the ON signal is turned on and then turned off), which causes the driver's confusion.

본 고안에서는 상기와 같은 문제점을 감안하여 초기 출력표시를 일정시간 지연시키는 구성을 가짐으로서 상기 문제점을 해결하는 것을 목적으로 한다.The present invention aims to solve the above problems by having a configuration for delaying the initial output display for a predetermined time in view of the above problems.

이하의 부수된 도면과 함께 본 고안의 전장품제어마이컴의 초기신호지연장치를 더욱 상세하게 설명한다.The initial signal delay device of the electronic device control microcomputer of the present invention will be described in more detail together with the accompanying drawings below.

제2도는 본 고안의 전장품제어마이컴의 초기신호지연장치를 도시하는 회로도, 제3도는 본 고안의 전장품제어마이컴의 초기신호지연장치의 제어 타이밍도로서 함께 설명한다.FIG. 2 is a circuit diagram showing an initial signal delay device of the electronic device control microcomputer of the present invention, and FIG. 3 is described together as a control timing diagram of the initial signal delay device of the electronic device control microcomputer of the present invention.

본 고안에서는 마이컴(1)에 의하여 제어되는 전장품은 출력단표시기(2)와, 상기 출력단표시기(2)를 제어하는 출력단표시제어IC(3)사이에 ENABLE 지연수단으로서 컨덴서(4)와 저항(5)을 연결함으로서 상기 컨덴서(4)와 저항(5)이 구성하는 시정수만큼 타임래그로서 지연하여 ENABLE 제어신호를 지연시킴으로서 일정시간 후, 정상적인 표시상태가 되도록 한다.In the present invention, the electrical equipment controlled by the microcomputer 1 includes the capacitor 4 and the resistor 5 as an ENABLE delay means between the output stage display 2 and the output stage display control IC 3 controlling the output stage display 2. ) By delaying the ENABLE control signal by a time lag by the time constant configured by the capacitor 4 and the resistor 5 so as to be in a normal display state after a certain time.

제3도에서 A는 마이컴제어신호를 도시하고, B는 출력표시장치의 제어신호, C는 ENABLE 단자지연신호를 표시한다. 여기에서 △T는 저항(5)과 컨덴서(4)에 의한 시정수만큼의 지연분을 의미한다.In FIG. 3, A shows a microcomputer control signal, B shows a control signal of an output display device, and C shows an ENABLE terminal delay signal. ΔT here means a delay by the time constant of the resistor 5 and the capacitor 4.

이상과 같은 본 고안의 전장품제어마이컴의 초기신호지연장치는 출력장치를 드라이브하는 제어IC의 신호를 일정한 시간동안 ENABLE 지연시킴으로서 시동초기의 불안정한 표시상태를 제거할 수 있게하여 표시의 신뢰성을 제공하고 회로를 안정화시키는 유용한 고안인 것이다.The initial signal delay device of the control electronic device of the present invention as described above provides a reliability of display by eliminating the unstable display state of the initial start-up by delaying the signal of the control IC driving the output device for a certain time. It is a useful design to stabilize.
