摘要
高速列车的行车调度指挥系统是确保列车运行安全和提高列车运行效率的核心中枢系统,是列车运行安全的保障。CTC各核心子系统之间相辅相成,共同作用,保证了CTC系统的功能正常发挥,因此分析CTC核心子系统之间的关联度十分重要。从行调子系统和助调子系统的功能分析入手,运用灰色关联度理论,构建CTC核心子系统关联度分析模型,计算行调子系统和助调子系统之间的关联系数和间接关联因子,以此类推,可以得到CTC系统中的其他核心子系统之间的关联度,为CTC系统行车调度提供了优化对象和目标。
As a core central system, the train operation dispatching system can raise the efficiency of train operation and ensures the safety of operation. Core subsystems supplement each other and work together to ensure the normal function of CTC system. Therefore, it is very important to analyze the correlation of CTC core subsystem. Starting with a functional analysis of the dispatching command subsystem and the assistant scheduling subsystem, We construct a correlation analysis model of CTC core subsystem using gray correlation theory, and calculate the correlation coefficients and indirect correlation factor of the dispatching command subsystem and the assistant scheduling subsystem. In the same manner, the degree of association of all CTC core subsystems can calculated and the calculation results can be provide the optimized object and target for the CTC.
