摘要
为方便、快捷地检测和评价列车的振动性能,将AD73360及DSP技术应用到列车振动测试系统中。采用AD73360将车厢内的振动加速度转换为数字信号,再利用DSP芯片的高速数据处理能力对加速度信号进行分析,同时在线得到列车运行的平稳性和舒适性指标。研究分析了列车振动测试系统,给出了系统设计方案,详细介绍了TMS320F2407DSP和AD73360接口电路的软硬件设计方法。实践证明,该系统能够准确、快速地在线测得列车运行的振动参数,为保障行车安全提供比较有效的依据。
In order to test and evaluation of trains＇vibration performance conveniently,AD73360 and DSP has been used in train vibration measure system. The vibration acceleration has been changed into digital signal, the acceleration signal was analysed in DSP chip, and get the trains＇comfort and sperling online. Based on study and analysis of the train vibration measure system, the author educes a technical plan. This paper introduces technique performance of AD73360 and provides design of interface circuit with TMS320F2407 DSP and software programming.
