SOFTWARE STRUCTURE OF A FAIL-SAFE AND FAULT-TOLERANT COMPUTER FOR RAILWAY SIGNALLING DEVICE

Open publisher page 3 citations

Abstract

Railway signalling control systems must not only have high reliability but also be fail-safe. The authors mentioned the hardware structure of a fail-safe and fault-tolerant computer for railway signalling in the conference of FTCS-10. A description is given of the software structure of this system. In designing the programming structure, a composite structured method is applied. The interlocking program is divided into a number of simple functional modules. To construct a high-security program, most of the algorithms for performing interlocking functions are specified according to those of traditonal relay interlocking system, as far as this is possible.
