Abstract

꼭 필요한 표시내용들을 모아 상태표시장치에 넣어 시스템 외부에 도출시켜 사용자나 취급자 모두가 이 상태 표시 장치를 이용하여 시스템의 정상 여부판단과 고장수리에 유용하게 활용할 수 있게 하는 특별한 별도의 부품을 사용하지 않고 간단히 구성하기 위해 주전원을 오아게이트(OR1)를 통해 입력하여 주전원 공급상태를 제1발광다이오드(LED1)를 통해 표시하고, 데이타버스(BD0)를 통해 모니터 상태정보를 디플립플롭(DF1)에서 래치하며, 데이타버스(DB1)를 통해 시스템의 아이들상태정보를 디플립플롭(DF2)에서 래치하여 상기 디플립플롭(DF2)의 출력에 따라 모니터 구동상태를 제2발광다이오드(LED2)에서, 상기 디플립플롭(DF2)의 출력에 따라 시스템의 아이들상태를 제3발광다이오드(LED3)에서 표시토록 구성됨을 특징으로 하는 키폰시스템의 시스템 체크 결과 표시회로.The necessary display contents are gathered and put into the status display device and brought out to the outside of the system so that the user or the handler can use this status display device to judge whether the system is normal and to use special special parts The main power source is inputted through the OR gate OR1 to display the main power supply state through the first light emitting diode LED1 and the monitor status information is transmitted to the D flip-flop DF1 via the data bus BD0 Latches the idle state information of the system through the data bus DB1 in the D flip-flop DF2 and outputs the monitor driving state from the second light emitting diode LED2 according to the output of the D flip- And the idle state of the system is displayed on the third light emitting diode (LED3) according to the output of the D flip-flop (DF2). And a display circuit.

Description

키폰시스템의 시스템 체크 결과 표시회로System check result display circuit of key telephone system

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is a trivial issue, I did not include the contents of the text.

제1도는 본 발명에 따른 회로도이다.Figure 1 is a circuit diagram according to the present invention.

Claims (1)

키폰시스템의 운용상태 표시회로에 있어서, 주전원을 오아게이트(OR1)를 통해 입력하여 주전원 공급상태를 표시하는 제1발광다이오드(LED1)와, 데이타버스(BD0)를 통해 모니터 상태정보를 래치하는 디플립플롭(DF1)과, 데이타버스(BD1)를 통해 시스템의 아이들상태정보를 래치하는 디플립플롭(DF2)와 상기 디플립플롭(DF2)의 출력에 따라 모니터 구동상태를 표시하는 제2발광다이오드(LED2)와, 상기 디플립플롭(DF2)의 출력에 따라 시스템의 아이들상태를 표시하는 제3발광다이오드(LED3)로 구성됨을 특징으로 하는 회로.The operating state display circuit of the key telephone system includes a first light emitting diode (LED1) for receiving a main power via a gate (OR1) and displaying a main power supply state, a second light emitting diode (LED1) for latching monitor state information via a data bus A flip-flop DF1, a D flip-flop DF2 for latching the idle state information of the system via the data bus BD1 and a second light emitting diode DF2 for indicating the monitor driving state according to the output of the D flip- (LED2), and a third light emitting diode (LED3) for indicating the idle state of the system according to the output of the D flip-flop (DF2). ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: It is disclosed by the contents of the first application.
