基于MATLAB的实时数据采集与分析研究

Real-time data acquisition and analysis based on MATLAB

数据采集系统在许多领域均得到了广泛应用,不过大多采集方式均基于目前流行的采集设备,而对自主开发的数据采集系统通过合理运用串口及MATLAB强大的数值计算和分析功能,实现基于MATLAB的实时数据处理和分析的方式则相对较少。本文简要介绍了MATLAB的数据采集工具箱的主要特征和数据采集的基本方法,尝试使用自主设计的数据采集系统,通过MATLAB软件进行实际人体心电图实时数据采集读取和分析处理仿真,实验结果表明了该方法的可行性,具有一定的应用价值。

Data acquisition system has been widely used in some fields. However, a majority of means of data acquisition are based on popular devices currently, it is sparse that use independent design and realize data acquisition and analysis by reasonably using serial, and powerful numeric-count and analytical capability of MTLAB. This paper briefly introduces main feature and basic method of data acquisition toolbox in matlab7.0, the outcome of experiments indicates that it is feasible to achieve real-time data acquisition, reading and analysis.
