SPKS在地铁CBTC系统中的应用

Application of SPKS in Metro CBTC System

阐述了地铁CBTC信号系统中实体SPKS的防护实现机制;以正线及场段SPKS的防护分区划分为例,通过对比不同防护分区的划分,说明了SPKS防护分区划分的原则;通过防淹门防护中应用SPKS的情况及变量的传递过程,对虚拟SPKS在防淹门接口中的应用进行了简述。对SPKS在CBTC系统中的工程应用有借鉴作用。

The protection realization mechanism of entity SPKS in metro CBTC signal system is described.Taking the protection zoning of SPKS in main line and depot as an example,the principle of SPKS protection zoning is explained by comparing the division of different protection zoning;Through the application of SPKS in flood gate protection and transmission process of variables,and the interface of virtual SPKS with flood gate is described.It can be used for reference in the engineering application of SPKS in CBTC system.
