摘要
针对动车组气动侧拉门硬线控制的不足,开展了基于TMS320LF2812A的侧拉门控制器的研究。分析了该门控制器的硬件框图、原理图以及软件控制算法,对外部硬线信号的监控以及当前门状态的分析进行开关门动作。同时采用敏感胶条检测法和时间检测法对障碍物进行检测。可靠的硬件结构及增强的状态机算法,实现了可靠的侧拉门控制。结果表明,该设计鲁棒性强,能满足系统要求。
To avoid the shortcomings of hard line control on railway passenger car pneumatic side door, the side door control unit （DCU） based on TMS320LF2812A is studied. The hardware block diagram, schematic diagram and software control algorithm of DCU are elaborated. The opening and closing of the door is controlled by monitoring the external signal and the current state of the door. The obstacle detection is performed by using sensitive edge detection method and timing method. The reliable hardware structure and enhanced state machine algorithm can achieve the reliable control of the side door. The results show that the design is robust,which can meet the system requirements.
