Research on door control system of high-speed Electric Multiple Units based on TCN

门控系统作为高速动车组安全运行的重要部件,具有状态多、结构功能复杂、可靠性要求高等特点,其可靠的工作与乘客安全息息相关。为了提高高速列车门控系统的可靠性及安全性,在列车通信网络的基础上,提出了高速动车组门控系统的网络结构,设计出门控器内部硬件结构,并使用FPGA+ARM共同开发列车车门控制器,有利于提高国内高铁列车门控系统的国产化率。首次提出从门控器的MVB通信结构提高了门控系统的可靠性,经实验测试,该网络系统很好地实现了门控系统的复杂功能。

As an important part of safe operation of high-speed EMU,the door control system has the characteristics of multiple states,complex structure and function,and high reliability requirements. Its reliable work is closely related to passenger safety. In order to improve the reliability and safety of high-speed train door control system,on the basis of train communication network,the paper puts forward the network structure of high-speed EMU gating system,develops the controller hardware structure design,and uses the FPGA + ARM for joint development of train door controller,to improve the localization rate of door system on high-speed trains in China. The MVB communication structure of door controller improves the reliability of door control system for the first time.
