基于USB2.0数据采集系统及在故障诊断中的应用

Data Acquisition System Based on USB2.0 and the Applications in the Fault Diagnosis

介绍了基于U SB 2.0接口的同步数据采集系统以及在机械故障诊断中的应用,给出了该系统的硬件组成原理及软件设计方法。由于该系统使用了CY 7C 68013,因而具有使用方便、即插即用等特点。采用L abV IEW 7.0软件,大大地增加了本系统在机械故障诊断中的灵活性和实用性。与笔记本电脑相连即可进行移动式在线的故障诊断和分析处理,具有较高的实用推广价值。

This paper introduces data acquisition system based on USB2. 0 and the application in the fault diagnosis and presents the system hardware composition principium and software designed method. With the help of CY7C68013, the system has the characteristic of convenience,and ＂plug and play＂, and so on . Because of introducing LabVIEW7. 0 software ,it enhances the flexibility and practicability of this system in the fault diagnosis. Connecting to notebook PC, it can make movable online fault diagnosis and analysis and process, so it has upper value of practicality and popularization.
