본 발명은 시스템 콘트롤러가 내장된 전원 제어회로의 구동방법에 관한 것이다.The present invention relates to a method of driving a power supply control circuit incorporating a system controller.

종래의 대부분의 전원 제어회로는 하드 웨어적인 단순한 스위치의 절환에 의하여 처리하기 때문에 오동작을 방지할 수 있는 조건 판단과 오동작 방지를 위한 제어 신호가 없는 실정이어서 전원이 안정화 되기전에 다음과 같은 문제점이 발생되는 것이었Most of the conventional power supply control circuits are handled by a simple switch of hardware. Therefore, the following problems occur before the power is stabilized because there is no control signal for determining the condition and preventing the malfunction. It was

(1) 입출력 단자가 순간적으로 정의되지 않고 (2) 시스템 콘트롤러와 주변 분배회로의 리셋트 타임을 수동소자에 의존하게 됨으로 주변 회로의 조건에 따라 오동작을 유발시키게 되며 (3) 외부 제어 신호에 의하여 전원을 제어하기 위하여는 상당수의 부수적인 회로가 필요하게 되는 것이었다.(1) The input / output terminals are not defined instantaneously. (2) The reset time of the system controller and the peripheral distribution circuit depends on the passive elements, causing malfunctions according to the conditions of the peripheral circuits. In order to control the power supply, a large number of additional circuits were required.

본 발명의 목적은 시스템 콘트롤러의 휴지 상태를 이용하여 소프트 웨어적으로 처리하고 주변 분배회로는 스위칭 소자를 사용하여 시스템 콘트롤러의 제어를 받을 수 있는 전원 제어회로의 구동방법을 제공하고자 하는 것으로 제어 신호에 의하여 동작 상태가 결정되는 시스템 콘트롤러에서 파워 전원 투입시 전원안정 및 리셋트 완료후 입출력 장치가 정상 동작되게 하고 파워 전원 차단시 중지동작 완료 후 불능신호, 스위칭 신호 차단하고서 콘트롤러가 휴지 상태로 돌입되게 한 것이다.An object of the present invention is to provide a method of driving a power supply control circuit that can be processed in software using the idle state of the system controller and the peripheral distribution circuit can be controlled by the system controller using a switching element. When the power supply is turned on, the I / O device operates normally after power stabilization and reset is completed. When the power supply is turned off, the controller enters the idle state by blocking the disable signal and switching signal after the stop operation is completed. will be.

이를 첨부 도면에 의하여 상세히 설명하면 다음과 같다.This will be described in detail with reference to the accompanying drawings.

제1도는 본 발명에 대한 회로도로서 전원공급부 (1)에 시스템 콘트롤러(4)에 안정된 전원을 공급시키는 레규레이터(2) 및 전원 스위칭부(5)에 전원을 공급하는 주변 분배용 정류회로(3)가 연결되게 구성시키고 기기전원 제어신호(a)에 의하여 구동되는 시스템 콘트롤러(4)에 입출력 장치(7) 및 주변 분배회로(6)가 연결되어 제어되게 구성시킨 후 시스템 콘트로러(4)의 스위칭 제어신호(e)가 공급되는 전원 스위칭부(5)에서 주변분배회로(6) 및 입출력 장치(7)에 전원이 투입되게 구성시킨 것이다.1 is a circuit diagram of the present invention, a regulator 2 for supplying stable power to the system controller 4 to the power supply unit 1 and a rectifying circuit 3 for peripheral distribution for supplying power to the power switching unit 5. ) And the input / output device 7 and the peripheral distribution circuit 6 are connected and controlled to the system controller 4 driven by the device power control signal a. The power is supplied to the peripheral distribution circuit 6 and the input / output device 7 by the power supply switching unit 5 to which the switching control signal e is supplied.

제2a도는 본 발명에서 파워 전원 투입시 각부 출력 상태도이고 제2b도는 본 발명에서 파워 전원 차단시의 각부 출력 상태도를 나타내고 있으며 제3a도는 본 발명에서 파워 전원 투입시의 구동 플로우 챠트이며 제3b도는 본 발명에서 파워 전원 차단시의 구동Figure 2a is a diagram showing the output state of each part when the power supply in the present invention, Figure 2b is a diagram showing the output state of each part when the power supply is cut off in the present invention, Figure 3a is a drive flow chart when the power supply in the present invention and Figure 3b is In the invention, driving at power off

즉, 파워 전원 투입시에는 「제어신호 공급」여부에 따라「동작상태」가 결정되면 주변분배회로(6) 및 입출력 장치(7)를 시스템 콘트롤러에서 제어한 후「전원 안정」이 되어야만 「리셋트 완료」시켜 입출력 장치가 정상동작을 하게 하고 있으며 파워 전원 차단시에는「제어신호 공급」여부를 판단하고「중지 동작완료」여부가 결정되면「불능신호 공급」,「시간지연」을 시킨 후 시스템 콘트롤러(4)가 「휴지상태」로 돌입되게 함으로써 전원 온-오프시에 야기되는 문제점을 해소시키고 있는 것이다.That is, when the power supply is turned on, if the "operation state" is determined according to the "control signal supply", the "reset power supply" must be reset after controlling the peripheral distribution circuit 6 and the input / output device 7 by the system controller. When the power supply is turned off, it is judged whether the control signal is supplied, and if it is determined that the stop operation is completed, the system controller is executed after the disable signal supply and the time delay. By causing (4) to enter the "rest state", the problem caused at the time of power on / off is eliminated.

이와 같이 구성된 본 발명의 동작 상태는 전원 공급이 중지된 정지상태, 순간 정전시와 같이 전원 공급이 차단 후 재공급되는 천이상태, 정상적인 전원이 공급되는 통전 상태로 구분되나 정지상태 및 상태에서는 대개 안정화되고 천이 상태에서 오동작이 생기게 되는 것으로 천이 상태중의 동작은 다음과 같다.The operating state of the present invention configured as described above is divided into a stop state in which the power supply is stopped, a transition state in which the power supply is resupplied after the power supply is cut off, and a energized state in which normal power is supplied, such as during a momentary power failure. In the transition state, a malfunction occurs. The operation during the transition state is as follows.

즉, 천이 상태중 파워 전원이 공급되는 때에는 제2도 및 제3a도와 같이 기기전원 제어신호(a)가 시스템 콘트로러(4)에 공급된 여부를 판단하여 제어신호(a)가 공급된 경우 시스템 콘트롤러(4)가 자체 발진을 하여 휴지상태에서 「동작상태」로 전환된다. 여기서「동작상태」란 안정된 전원에 의하여 구동하고 있을때를 뜻하며「휴지상태」란 모든 내부 동작이 중지되 클럭 발진이 멈추어진 상태이다.That is, when power power is supplied during the transition state, it is determined whether the device power control signal a is supplied to the system controller 4 as shown in FIGS. 2 and 3a, and when the control signal a is supplied. The controller 4 oscillates itself and is switched from the rest state to the "operation state". In this case, the "operation state" refers to when it is driven by a stable power supply. The "operation state" refers to a state in which all internal operations are stopped and clock oscillation is stopped.

그후 시스템 콘트롤러(4)가 초기화된 후 입출력 장치 불능신호(b)를 입출력 장치(7)에 인가시켜 입출력 장치가 불능 상태가 되게함과 동시에 동작제어 신호 및 데이타 라인(f)을 통하여 필요한 동작 제어 신호를 입출력 장치(7)에 보내어 전원이 투입되는 순간 발생할 수 있는 오동작을 방지한다.Thereafter, after the system controller 4 is initialized, the input / output device disable signal b is applied to the input / output device 7 to make the input / output device disabled, and at the same time, the required operation control is performed through the operation control signal and the data line f. The signal is sent to the input / output device 7 to prevent a malfunction that may occur at the moment of power-on.

이와 같은 오동작 방지 행위가 종료되면 시스템 콘트롤러(4)는 스위칭When the malfunction prevention operation is completed, the system controller 4 switches.

또한 제2도 및 제3b도와 같이 파워 전원 차단시에는 기기전원의 제어신호(a)가 차단되는 것을 시스템 콘트롤러(4)에서 감지하여「현재의 동작을 중지함」과 같은 루틴에 의하여 수행중인 동작을 중지하고 휴지상태가 될때까지 모든 입출력 상태를 셋트시킨다. 그후「중지동작 완료?」상태를 판단하여 동작 완료가 확인되면 입출력 장치의 불능신호(b)를 책티브(Active)로 하여 입출력 단자의 기능을 차단시켜 파워 전원이 차단되면서 발생되는 오동작을 대비하여 완전한 불능 상태가 될때까지 시간이 걸린 경우에는 「시간지연」루틴 수행후 스위칭 제어 신호를 차단시키고「휴지 상태」로 돌입하여 시스템 콘트롤러(4)는 자체 클럭 발진을 멈춘 휴지 상태가 되는 것이다.In addition, as shown in FIGS. 2 and 3b, when the power supply is turned off, the system controller 4 detects that the control signal a of the device power supply is cut off and is being performed by a routine such as "stopping the current operation." Stops and sets all I / O states until it is idle. After that, when the operation completion is confirmed by judging the state of "stop operation completed?" If it takes time until it becomes completely disabled state, after performing the "time delay" routine, the switching control signal is cut off, and the system enters the "rest state", and the system controller 4 becomes the dormant state which stopped its own clock oscillation.

이상에서와 같이 본 발명은 마이콤으로 구성되는 시스템 콘트롤러의 동작 상태와 휴지 상태를 이용하여 전원-오프시에(천이상태)생기는 오동작을 소프트 웨어적인 처리로 인하여 방지할 수가 있는 것으로 입력단자 중 오동작을 유발시키는 단자를 불능 상태로 하여 전원이 공급되게 하여 입출력 단자가 순간적으로 정의되지 아니하는 문제점을 배제하고 주변 분배 회로의 리셋트는 시스템 콘트롤러의 논리적 제어에 의하여 타이밍 처리되게 하여 주변 회로에 의한 오동작을 방지할 수가 있어 여러가지 전자기기의 전원 회로로 널리 사용될 수 있는 효과가 있는 것이다.As described above, the present invention can prevent malfunctions generated during power-off (transition state) by using software processing by using the operating state and the idle state of the system controller composed of the microcomputer. Eliminate the problem that the input and output terminals are not defined instantaneously by disabling the causing terminal to be disabled, and the reset of the peripheral distribution circuit is timed by logical control of the system controller to prevent malfunction by the peripheral circuit. It can be used as a power supply circuit of various electronic devices that can be widely used.
