平轮振动信号采集系统的开发

Development of Collection System for Horizontal Wheel Vibration Signal

针对地铁车辆车轮踏面擦伤造成车辆行进过程中产生轮轨系统的耦合振动给车辆走行部带来的损害，描述了应用DSP技术设计PCI总线标准的数据采集卡的研制，以及VxWorks操作系统下数据采集卡驱动程序的开发。

In the running process the produced coupled vibration of track system due to scrapes on locomotive wheel can bring damage to the locmotive＇s running gear. This article describes research of data acquisition card using standard of PCI busbar designed by DSP technology and driver development of data acquisition card under Vx Works operation system.
