轨道交通车辆制动管理方式探讨

Discussion on Brake Management of Rail Transit Vehicles

归纳了轨道交通车辆几种典型的制动管理方式,分析了各种制动管理方式下的网络通信数据流以及VCU(车辆控制单元)、EBCU(电子制动控制单元)和TCU(牵引控制单元)的相关功能。同时,在对比分析4种制动管理方式优劣势的基础上,基于轨道交通车辆不同的制式和运用场景,建议高铁列车、动车组采用方式4,市域车、地铁列车采用方式3,其他类型车辆采用方式1或方式2的制动管理方式。

Several typical brake management methods for rail transit vehicles are summarized,and the data flow of network communication and relevant functions of vehicle control unit(VCU),electronic brake control unit(EBCU)and traction control unit(TCU)are analyzed under all brake management methods.Meanwhile,after the comparative analysis of strength and weakness of all four brake management methods,it is recommended to apply method 4 for high-speed railway train and electric multiple unit(EMU),and method 2 for urban rail/metros,and method 1 or 2 for other types of vehicles.
