基于LCU的地铁车辆控制电路改造研究

Research on Reform of Control Circuit on Metro Vehicles Based upon LCU

针对广州13号线地铁车辆,研究了控制电路中使用LCU替换前期采用的继电器控制方案,详细介绍了研制背景、LCU运用范围确定、LCU设备概述及电气原理图设计、硬件组成与选型、软件设计、装车验证等内容。

In view of the metro vehicles for Guangzhou No. 13 Line, the control scheme to replace relays applied in the early stage with LCU in the control circuit is researched. Such contents as the development background, determination of LCU operation scope, general description and electrical diagram design of LCU equipment, hardware composition and model selection, software design and verification on vehicle are described in detail.
