城轨列车三取二逻辑控制单元设计

Design of LCU based on two out of three method in urban train

针对列车复杂运行环境以及现有LCU的运用情况,提出一种更可靠的基于三取二控制技术的城轨列车LCU设计方法,重点研究了在软件算法和硬件设计上的三取二设计思想,并对其进行模块化设计。该三取二LCU系统已示范应用于广州市轨道交通二十一号线两列车,应用情况良好。

In view of the complex running environment of the train and the application of the existing LCU, a more reliable design method of the urban train LCU based on two out of three control technology is proposed. The design idea of two out of three method in the software algorithm and hardware design is studied emphatically, and the modular design is carried out. The LCU system based on two out of three method has been demonstrated and applied to the two trains of Guangzhou Rail Transit Line 21, and the application is good.
