Abstract(in English) | This is a retrospection paper on the development of the fail safe computer systems in the railway signaling field. At the start, this paper describes the fail safe systems in the railway signaling. In order to satisfy the fail safe requirements, the first system had used the fail safe parametrons as logical elements and the trance former typed ROM. This system had been developed in 1967. The second system had used the micro-processors 8085, and had been practically used in 1985. I had been concerned in development of the other 2 or 3 systems. This paper describes the episodes on the development of the fail safe computer systems. |
