摘要
平稳性指标是衡量铁道车辆运行品质的主要技术参数。根据ARM处理器AT91RM9200的工作原理和性能特点,提出了一种基于ARM嵌入式技术的车辆运行平稳性系统设计方案。系统采用了嵌入Linux操作系统,分析了系统的软硬件功能结构。系统性能可靠,价格低廉,适用于一般振动信号的采集和分析。
Smoothness criterion is one of the important items which show the quality of running railway vehicles.Accordlng to the ARM CPU AT91RM9200 principle of work and performance, this paper presents a set of design scheme on vehicle smoothness criterion measuring system based on ARM. The system adopts embedded Linux OS, analyzes the functional configuration of system hardware and software, which is also applicable for detection of general vibratory signal.
