摘要：
针对当前国内应用于机械故障诊断的数据采集分析仪器成本高、实时性差等缺陷,设计了一套实时数据采集分析系统,能进行实时数据采集处理、下位机存储和上位机分析。系统整体采用主从结构;下位机采用8051f020单片机作为mcu,数据采用fram(铁电存储器)存储,通讯层主要由uart模块组成,实现数据采集、处理、存储及传输等;上位机软件采用vc 和matlab融合技术,主要实现路径设置、数据实时显示、数据处理等功能;同时介绍了在vc 中调用matlab引擎实现接口通信的方法。应用实例表明:系统具有很好的实时性和可靠性。

abstract: the domestic apparatus of data collection and analysis, which is used in machinery fault diagnosis, has the defects of high costs and poorly real-time. a device which can be capable of real-time data acquisition and processing has been designed for real-time data acquisition and analysis. the next-bit machine is used to store and the pc is used to analyze. and 8051f020 is used as the mcu of the lower place machine, the data is stored in the fram, and uart module is used as the main part of communication layer. the lower place machine is used to realize those functions such as data collection, processing, storage, transmission and so on. the software of top pc used the integration of vc and matlab, the main function are path settings, real-time data display, data processing. it also introduced the method of invoking matlab engine from vc to achieve communication. finally, an example is given to show that this system has a good real-time performance and reliability.
