An automatic end changing method of a multi-source system locomotive comprises the steps that S1, whether an electric key quits occupation or not is judged, and if the electric key does not quit occupation, automatic end changing is not activated; if the electric key is not occupied, parking braking is applied; s2, judging whether the main power supply is closed before the electric key quits the occupation, and if the main power supply is not closed, not activating the automatic end change; if the main power supply is closed, maintaining the current power supply mode; s3, after occupying the new occupying end, judging whether the power supply mode of the new occupying end is consistent with the power supply mode before the end is changed; if the power supply modes are consistent, activating automatic terminal switching; and if the power supply modes are inconsistent, traction blocking is applied. Compared with the prior art, the operation limitation that automatic end changing can be activated only by switching the power supply mode firstly is avoided, the risk of conflict operation of the power supply mode possibly caused by movement of the locomotive is avoided, the automatic end changing process is simplified, and then efficient and convenient automatic end changing is achieved on the premise that a power source for automatic end changing is not interrupted.

    一种多源制机车的自动换端方法,包括:S1、判断电钥匙是否退出占用,若电钥匙未退出占用,则不激活自动换端;若电钥匙退出占用,则施加停放制动;S2、判断电钥匙退出占用前的主电源是否闭合,若主电源未闭合,则不激活自动换端;若主电源闭合,则维持当前供电模式;S3、占用新占用端后,判断新占用端的供电模式与换端前的供电模式是否一致;若供电模式一致,则激活自动换端;若供电模式不一致,则施加牵引封锁。与现有技术相比,本发明避免了需要先转换供电模式才能激活自动换端的操作限制,避免了机车移动可能导致的供电模式冲突运行的风险,简化了自动换端流程,进而实现了在自动换端的电源不中断的前提下进行高效便捷的自动换端。
