新一代铁路计算机双机切换与外设延长系统的研究

摘要

Active-standby switching and peripheral signal extending were two significant functions of the modern railway computer system. To meet the requirement of the synthetic automation of marshaling yard, the New Generation Railway Active-Standby Switching and Peripheral Signal Extending System was developed on basic of the preceding technique. This paper expounded it in composition, principle and design of hardware and software.%为满足编组站综合自动化(SAM)系统的需要,在原有双机切换设备和外设延长设备技术的基础上,研究开发了新一代铁路计算机双机切换与外设延长系统.本文从设备组成、工作原理和软硬件设计等方面对其进行阐述.
