基于Labview的车辆模拟量信号量采集系统

Labview-based Vehicle Analog Signal Acquisition System

近年来,随着电子技术和计算机技术的高速发展,测试技术也在不断地更新换代。早期的自动检测和手动检测相结合的方法由于自动化程度偏低、测量精度低、实时性差等缺点,逐渐被微机化的测试系统所取代。文章选用以计算机和数据采集设备NI-USB6009为硬件设备,以Labview为软件开发平台,配合必要的传感器、信号调理设备和数据采集卡组成了一套多通道的车辆模拟量数字量信号采集系统。本课题研究开发的采集信号系统方案具有良好的扩展性,并且具有速度快、精度高、界面友好的特点。

With the development of computer technique,test technology is also constantly updated.The combination of early automatic detection and manual detection has been replaced by a computerized test system because of its low automation,low measurement accuracy,and poor real-time performance.Therefore,the author develops a muti-channel Analog quantity and Digital quantity measurement and analysis system based on computer as hardware workbench,Laboratory Virtual Instrument Workbench(Labview)as a development software,essential sensor,signal conditioner and NI USB-6009 data acquisition cards.This plan enjoys a lot of advantages such as excellent expanding performance,high precision and friendly interface.
