동기식 정보 송 ·수신장치의 고장진단방법Fault Diagnosis Method of Synchronous Information Transceiver

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제 1 도는 본 발명 동기식 정보 송 ·수신장치의 블록도, 제 2 도는 본 발명의 고장진단방법 흐름도.1 is a block diagram of a synchronous information transmitting and receiving apparatus of the present invention, and FIG. 2 is a flowchart of a fault diagnosis method of the present invention.

Claims (1)

중앙처리장치(2)에서 피롬(1)의 프로그램내용에 의해 호스트 메모리(3)의 송신정보데이타를 전송버퍼(7) 및 전송 FIFO(5), 드라이버(4)를 통해 읽어와 동기식 통신프로세서(9)를 통해 송출하고, 그 동기식 통신프로세서(9)에 수신되는 수신정보 데이타를 중앙처리장치(2)에서 읽은 후 상기 드라이버(4) 및 수신 FIFO(6), 수신버퍼(8)를 통해 상기 호스트메모리(3)에 저장하는 동기식 정보 송 ·수신장치에 있어서, 송신정보 데이타를 송출한 후 소정시간이내에 응답신호가 수신되지 않거나 비전송수신이 발생된 경우에 상기 중앙처리장치(2)에서 에러감지용상태버퍼(10)를 인에이블시켜 상기 각부의 상태출력을 검사하고, 이때 정상일 경우에는 송신정보를 재송신하여 응답신호를 다시 기다리고 , 에러일 경우에는 그 해당에러상태를 상기 동기식 통신프로세서(9)를 통해 음극선관(11)에 표시함과 아울러 송신을 중단하게 함을 특징으로 하는 동기식 정보 송 ·수신장치의 고장진단방법.In the central processing unit 2, the transmission information data of the host memory 3 is read out through the transfer buffer 7, transfer FIFO 5, and driver 4 by the program contents of the pyrom 1, and the synchronous communication processor ( 9) and after receiving the received information data received by the synchronous communication processor 9 from the central processing unit 2, the driver 4, the receiving FIFO 6, and the receiving buffer 8 are read. A synchronous information transmitting / receiving apparatus stored in the host memory (3), wherein the central processing unit (2) detects an error when a response signal is not received or a non-transmitting reception occurs within a predetermined time after sending the transmission information data. Enable the status buffer 10 to check the status output of each part, and if it is normal, retransmit the transmission information and wait for the response signal again, and if the error is found, the synchronous communication processor 9 Through A method for diagnosing a failure of a synchronous information transmitting / receiving device, characterized by displaying on a cathode ray tube 11 and stopping transmission. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
