Abstract

본 발명은 사스(SASS) 시스템의 원격 경보 수신보드(RARB)에서 퍼스컴(PC)에로의 병렬 통신을 행하는 회로에 관한 것으로 특히 통신속도 및 통신 품질을 향상시키는 데 적합하도록 한 것이다.The present invention relates to a circuit for performing parallel communication from a remote alarm reception board (RARB) of a SARS system to a personal computer (PC), and is particularly suitable for improving communication speed and communication quality.

종래의 기술은 PCU(40)에서 데이터 송신시 직렬데이타 형태로하여 송신하고 이것을 다시 쉬프트 레지스터(50)에서 병렬데이터 형식으로 변환하기 때문에 데이터 처리보드(60)로의 데이타 송신시 송신시간이 오래걸리고 쉬프트 레지스터에서 데이터 변환시 에러를 유발하는 문제점이 있었다.In the prior art, since the PCU 40 transmits data in the form of serial data and converts it back to the parallel data format in the shift register 50, the transmission time takes longer when the data is transmitted to the data processing board 60. There was a problem that caused errors when converting data in registers.

본 발명은 따라서 원격정보 수신보드(RARB)에서 PC 내부에 있는 데이터 처리보드(60)로의 데이터 전송을 CPU(40)의 메모리 용량확장을 위한 출력포트를 이용하여 직렬데이터로의 변환작업을 거치지 않고 병렬데이터를 곧바로 전송하는 통신회로를 이루도록 한 것이다.Therefore, the present invention does not undergo data conversion from the remote information receiving board (RARB) to the data processing board 60 inside the PC without converting the data into serial data using an output port for expanding the memory capacity of the CPU 40. It is to establish a communication circuit for transmitting parallel data directly.
