基于MATLAB的实时数据采集与分析系统的实现

System for Real-time Data Acquisition and Analyses Based on MATLAB

用数据采集卡构建的数据采集系统,一般价格昂贵且难以与实际需求完全匹配。为此,提出了一种新的简单可行的方案,利用计算机本身的软硬件资源,不需添加其他任何设备即可构成数据采集与分析系统。详细介绍了该系统的设计方法,使用MATLAB语言编制了简洁的图形用户界面,该界面操作方便,并且可以根据用户的需求进行功能扩充。最后给出了详细的试验结果。

The data acquisition system made up of data acquisition card is expensive and is hard to meet the practical demands.To handle this problem,a new and feasible scheme is introduced,the system is established by applying the software and hardware resources of computers and without adding any other device.The design procedure of the system is discussed in detail,a simple graphic user interface (GUI) is programmed with MATLAB language,which is convenient to be operated and its function can also be expanded according to users’ demands.Some experimental results are also given finally.
