Abstract
본 발명의 구동상태 표시장치는 다수의 보드가 슬롯에 장착되는 기기에서 각 부위의 동작상태를 표시하는 것이다.The driving state display device of the present invention is to display the operation state of each part in the device in which a plurality of boards are mounted in the slot.
본 발명은 RQ 보드 및 RP 보드가 어드레스 버스 요청신호와 데이타 버스 요청신호를 발생하는지를 시각적으로 표시함은 물론 시스템의 고장 및 입출력 에러의 발생을 시각적으로 표시하여 시스템의 동작상태를 바로 확인할 수 있도록 하는 것으로서 다수의 버퍼 및 다수의 표시용 발광 다이오드를 직렬로 연결하고, 버퍼의 제어단자에 RQ 보드 및 RP 보드가 발생하는 어드레스 버스 요청신호 및 데이타 버스 요청신호와, 시스템의 고장신호 및 입출력 에러신호가 각기 인가되게 하여 어드레스 버스 요청신호, 데이타 버스 요청신호, 시스템의 고장신호 및 입출력 에러신호가 발생시 버퍼가 도통상태로 되면서 발광 다이오드를 점등시키게 함으로써 어드레스 버스 요청신호, 데이타 버스 요청신호, 시스템의 고장신호 및 입출력 에러신호가 발생시 이들 신호에 따라 발광 다이오드가 선택적으로 점등되어 사용자는 발광 다이오드의 점등상태로 시스템의 동작상태를 바로 확인할 수 있다.The present invention provides a visual indication of whether the RQ board and the RP board generate an address bus request signal and a data bus request signal, as well as a visual indication of the occurrence of system failure and input / output errors, so that the operation status of the system can be immediately confirmed. A plurality of buffers and a plurality of display light emitting diodes are connected in series, and an address bus request signal and a data bus request signal generated by an RQ board and an RP board and a system fault signal and an input / output error signal are connected to a control terminal of the buffer. When the address bus request signal, the data bus request signal, the system fault signal and the input / output error signal are generated, the buffer is turned on and the LED is turned on so that the address bus request signal, the data bus request signal, and the system fault signal are applied. And I / O error signals when these signals occur According to the light-emitting diode is selectively lighting the user can immediately check the operation state of the system to a lighting state of the LED.
