The automatic configuration(inauguration)of train communication networks(TCN)is emphasized as a distinguishing feature of train control and management systems(TCMS).This process establishes the composition and sequence of nodes,identifies the master node,and determines node orientations relative to the master node within TCNs,laying a foundation for train control and manage-ment.In scenarios of TCMSs based on wireless communication,the absence of physical wire/cable connections between nodes in the wireless train backbone(WLTB)network renders automatic inauguration in traditional ways impractical.Consequently,manual setting of parameters remains the prevailing configuration practices in engineering applications.Furthermore,the automatic configuration is de-manded in a dynamic manner for virtual coupling(VC)systems,where multiple trains are virtually coupled into platoons through WLTB.The configuration mode by manual parameter setting is not viable,since following trains run in an automatic operation mode.This paper analyzed the TCN and WLTB inauguration as well as VC platoon coupling/uncoupling,and delved into the nature and root causes of obstacles encountered in the initialization and dynamic configuration of train platoons based on wireless communication.The findings inspired the introduction of an expanded network system that merges TCMSs and signaling systems to provide an automatic con-figuration solution.This solution included automatic configuration methods,layered functions,and system architecture for communica-tion network-based train control(CBTC)systems,focusing on automatic train operation aspects.Additionally,the paper also explored CBTC-related domains for potential future research endeavors.
