The study of EMUs catenary＇s dynamic parameters detection system based on DSP technology

针对采用检测方式无法较好地实现对动车组弓网高频动态特性进行测试的问题，开发了基于TMS320C5402的检测系统，以实现完全意义上的非接触式接触网检测。文中计算了相关检测算法，介绍了系统的总体设计，详细说明了系统的硬件设计，完成了系统的软件主程序流程图设计。 目录摘要：本文提出了通过测量动车组受电弓滑板变化状态并用配套算法计算出相应参数的方法，设计了检测系统。

According to the problem that the existing detection method can not be a better way fo achieve the EMUs panfograph-cafenary high-frequency dynamic testing, the paper develops detection systems based on TMS320C5402 to achieve complete non-contact catenary detecting. In the paper, relevant defection algorithm has been computed, overall design of the system has been described, the system hardware design has been shown in detail, and the main program flow chart of the system has been designed. Catalogue Abstract： The paper proposes a method which can calculate the corresponding parameters by measuring the changes of EMUs pantograph slider and using matching algorithm, and designs the defection system.
