摘要
为了增强CTCS-3级列车控制系统ATP车载设备的可靠性,在分析车载设备的外部接口与内部功能的基础上,结合时序状态机的相关理论分析,提出一种能够使得CTCS-3级列车控制系统ATP车载设备主备系无扰动切换的指导方法。针对该方法,结合相关功能点,进行分析,得出该方法的可行性,此研究成果对指导双系无扰动切换具有较大的实用价值。
In order to enhance the reliability of CTCS-3 onboard ATP equipment, the paper puts forward a method of non-disturbance switching between main and standby CTCS-3 ATP on-board systems based on functional analysis of external and internal interfaces of the systems and the theory analysis of sequence state machine. The analysis of the relevant functions of the systems shows that the method is feasible and can be applied to guide most kinds of non-disturbance switching between dual redundant systems, which has great practical value.
