The invention discloses a redundancy switching method for a maglev train levitation control board card and a related assembly, and relates to the field of train control. Two suspension control board cards are arranged at a suspension point and are respectively a main board card and a slave board card, the main board card and the slave board card interact through a main board card verification signal and a slave board card verification signal so as to judge whether the main board card needs to be switched to the slave board card for control currently, and if the main board card needs to be switched to the slave board card, the slave board card is switched to the slave board card for control. If yes, the slave board card obtains the control authority of the suspension point from the main board card. It can be seen that no board card needs to be additionally arranged to conduct switching control between the suspension control board cards, information interaction can be conducted between the master board card and the slave board card, when switching is needed, the slave board card obtains the control authority from the master board card, and redundancy control over the suspension point by the master board card and the slave board card is achieved; and the problem that the maglev train cannot normally run in a suspension mode due to the fact that the suspension point cannot be controlled when one suspension control board card breaks down is solved while the cost is saved.
本发明公开了一种磁浮列车悬浮控制板卡冗余切换方法及相关组件,涉及列车控制领域。在一个悬浮点设置两个悬浮控制板卡,分别为主板卡和从板卡,主板卡和从板卡之间通过主板卡验证信号和从板卡验证信号进行交互,以判断当前是否需要从主板卡切换至从板卡进行控制,若需要从主板卡切换至从板卡,则从板卡从主板卡获取对悬浮点的控制权限即可。可见,无需额外设置板卡进行悬浮控制板卡之间的切换控制,主从板卡之间可进行信息交互,当需要切换时由从板卡从主板卡获取控制权限,实现主板卡和从板卡对悬浮点的冗余控制,在节省成本的同时避免当一个悬浮控制板卡故障时无法对悬浮点进行控制导致磁浮列车无法正常悬浮行驶的问题。
