The invention discloses a rail transit vehicle and a dynamic pantograph rising control system and method thereof. The control system comprises a programmable logic control unit. The first relay is connected with a first input point of the programmable logic control unit; the first relay is used for providing a first input signal for the programmable logic control unit according to the size relation between the vehicle running speed and the dynamic pantograph rising speed limiting threshold value. The second relay is connected with a second input point of the programmable logic control unit; when a contact network is arranged above the pantograph, the second relay provides an effective second input signal for the programmable logic control unit; and the output point of the programmable logic control unit is connected with the pantograph rising valve, responds to the effective input signal and sends a pantograph rising command to the pantograph rising valve. According to the method, the risk of pantograph net damage caused by dynamic pantograph rising of the multi-power-source rail transit vehicle at the too high speed is greatly reduced.

    本发明公开了一种轨道交通车辆及其动态升弓控制系统、方法,控制系统包括可编程逻辑控制单元;第一继电器,该第一继电器与可编程逻辑控制单元的第一输入点位连接;第一继电器用于根据车辆运行速度与动态升弓速度限制阈值的大小关系为可编辑逻辑控制单元提供第一输入信号;第二继电器,与可编程逻辑控制单元的第二输入点位连接;当受电弓上方有接触网时,第二继电器为可编辑逻辑控制单元提供有效第二输入信号;可编程逻辑控制单元输出点位连接受电弓升弓阀,输出点位响应于有效输入信号,向电弓升弓阀发送升弓命令。本发明极大地降低了多动力源轨道交通车辆在过高速度动态升弓时造成弓网损伤的风险。
