摘要
介绍一种2乘2取2架构的轨旁安全计算机平台iBase22-TSP,该平台为卡斯柯公司全自主研发并通过了SIL4级欧标认证,应用于城轨CBTC信号系统。描述其系统组成,软硬件架构以及2取2比较、冗余切换等相关安全原理;通过概述基于该安全计算机平台在城轨ZC/LC产品中的使用情况,展望该平台应用于其他安全产品中的前景。
This paper introduces a track-side safety computer platform, iBase22-TSP, which a- dopts a double-2-out-of-2 structure. This platform is independently developed by CASCO and has passed through SIL4 ISA of European standards and has been used in CBTC signal system of ur- ban railway. We describe the constitution and hardware ＆ software structure of the system, and describe the related safety principles including double-2-out-of-2 comparison and redundant swit- chover. An overview of its application in ZC/LC product for urban rail transit is summarized and the prospect of its application in other safety product is also expected.
