摘要
针对我国铁路机车信号现有各种制式而研制出一种通用式机车信号。它由微机控制,适用于非电气化区殴。在着重分析了这种装置技术难点的基础上,以保证可靠工作为前提,详细研究了本装置的硬件结构、软件结构。同时提出实时控制系统中应用微机、微电子电路保证具有“故障-安全”性能的措施。本装置已在铁路现场扩大应用较长时间,工作可靠,并通过了部级鉴定。
This paper describes a universal type of cab signalling,which has been developed for replacement of the different types of cab signalling existing in Chinese railways. The new system is controlled by computer and is a applicable in unelectrified railways. The teahnical difficulties about the system are analysed, and the hardware and software are given such a design as to ensure the reliability of the system. Moreover, it is discussed how the 'fail-safe' function is realized when the computer and micro-electronic elements are used in this realtime controlled system. The system has been applicated to railways for quite a long time and proved reliable of working.
