基于ARM的列车振动检测系统研究

摘要

随着高速铁路和城市轨道交通的不断发展，更加便携、智能的列车振动测试仪也陆续出现。为了实现对列车运行状态的实时监控，文章提出设计一款多用途的便携式列车振动分析检测仪，仪器采用双ARM处理器实现传感器信号采集和相关处理，同时采用CPLD芯片进行加速度信号的AD模数转换，提高了系统的数据处理和存储能力，增强了可靠性。%With the development of high speed railway and urban rail transit,there are starting to appear more portable intelligent train vibration testers.In order to realize the real-time monitoring the running state of the train,it put forward to design a multi-purpose portable train vibration detection system..It adopts dual ARM processor to acquire and process the sensor signal.,while using CPLD to realize the modulus converdion of acceleration signal.Thus,it improves the system ability of processing data and storage and enhances the reliability.
