列车控制系统中不中断行车的系统在线替换

On-Line Replacement for Automatic Train Control System

大城市的轨道交通网络要求不间断的服务,这就需要在系统功能扩展时能保证在线运营.基于日本现行列车自动控制系统,为了在现有系统环境下使原系统逐步在线过渡到新的列车自律控制系统,使用了基于网关的过渡技术,提出两种测试方法,运用保证性评价技术加以分析,从而使系统在功能扩展与新旧系统过渡时能提高可靠性、在线性等保证性指标.

In order to satisfy non-stop services in metropolitan railways,railway systems must assure on-line expansion.On the enviroment of current Japanese automatic train control system,for building a new communication-based autonomous train control system,this paper used a gateway-based replacement technology and proposed two different methods for test and assurance evaluation technology.Assurance of test was calculated and we analyzed properties of test,chose best test method.That is to say,we can assure on-line expansion.
