The invention provides a rail transit traction system safety function distribution method and system and electronic equipment, and the method comprises the steps: carrying out the hazard analysis of a rail transit traction system, and determining the hazard type of each top layer and the safety integrity level which needs to be satisfied; aiming at any top-layer hazard type, determining a safety function which the rail transit traction system needs to have in the existing operation scene, and distributing a safety integrity level of the safety function according to a safety integrity level requirement which the top-layer hazard type needs to meet, so as to form at least one safety function distribution tree corresponding to the top-layer hazard type; and obtaining a safety function distribution result of the rail transit traction system in combination with each top layer hazard type and the corresponding safety function distribution tree. According to the method, the fault tree analysis method can be adopted to perform traction system safety function distribution, the damage and safety integrity level of the rail transit vehicle traction converter subsystem can be determined, and the function safety design of the rail transit traction system can be effectively guided.

    本发明提供一种轨道交通牵引系统安全功能分配方法、系统及电子设备,方法包括:对轨道交通牵引系统进行危害分析,确定各顶层危害类型及其需满足的安全完整性等级;针对任一顶层危害类型,确定轨道交通牵引系统在现有运行场景下需具备的安全功能,并根据顶层危害类型需满足的安全完整性等级要求分配安全功能的安全完整性等级,形成与顶层危害类型对应的至少一种安全功能分配树;结合各顶层危害类型以及对应的安全功能分配树获取轨道交通牵引系统的安全功能分配结果。本发明能够采用故障树分析方法进行牵引系统安全功能分配,能够明确轨道交通车辆牵引变流器子系统危害及安全完整性等级,可以有效指导轨道交通牵引系统功能安全设计。
