Abstract

본 발명은 건설 중장비중 가장 많이 사용되는 굴삭기의 보드내 프로세서(1)와 병렬 버스(5)와의 메모리(4) 사용 중재를 이용한 전자제어장치에 관한 것으로 데이타를 저장하기 위한 메모리(4)와 보드내 프로세서(1)로부터 버스제어신호에 응답하여 복수의 인터페이스에서 메모리(4) 사용을 요청할 경우 중재하는 버스 중재기(2)와 버스 중재기(2)의 중재 결정에 의해서 보드내 프로세서(1)와 메모리(4)를 연결시키고 병렬버스(5)와 메모리(4)를 연결시켜 주는 버스 교환기(4)로 구성되어 여러 관절을 동시에 제어할 수 있으므로 조작법이 간단하게 되어 굴삭기를 최대한 활용할 수 있다.The present invention relates to an electronic control device using mediation of the memory (4) between the onboard processor (1) and the parallel bus (5) of an excavator which is most used among construction heavy equipment. In-board processor (1) by arbitration decision of the bus arbiter (2) and the bus arbiter (2) that arbitrate when requesting the use of memory (4) in a plurality of interfaces in response to a bus control signal from my processor (1) And a bus exchanger (4) connecting the memory (4) and connecting the parallel bus (5) and the memory (4) can control multiple joints at the same time, so the operation is simple and can make full use of the excavator.
