摘　　要：针对目前折关检测的缺点,介绍了采用AT 89C51单片机为核心,设计一个智能化列车折关检测装置;在详细分析列车制动原理的基础上,重点讨论了系统的工作原理和硬件设计,采用独特的检测手段;该系统能够及时检测出列车折角塞门是否被关闭,并蜂鸣报警及测量管压;系统投入运行后,应用结果表明,该检测系统运行稳定可靠,检测精度高,检测精度达到了±2节内,具有很大的推广价值。Aiming at the fault detection of train angle cocks currently, this paper introduces a intellectualized fault defection instrument of train angle cocks based on AT89C51 MCU. On the basis of analyzing train braking principle detailedly, we discuss specially the systematic operating principle and hardware design, and adopt the unique detecting approach. It can detect whether the train angle cocks are closed, and alarm drivers. Since the system is put into operation, the application shows that this system runs stably and accurately, the deteclion precision has achieved ±2, The technology and methods adopted in the system are worthy of using abroad.
