基于MATLAB的控制设备及获取数据方法的研究

Method of Controlling Instruments and Data Acquisition Based on MATLAB

在介绍Instrument Control Toolbox的功能的基础上,设计了MATLAB环境下计算机通过GPIB接口与测量设备进行通信的过程,给出了具体的数据传输的软、硬件实施方案。以函数发生器为例研究了设备的控制和数据的获取方法,给出了部分MATLAB程序。实验结果表明该方法具有编程简便,数据处理能力强的特点,具有一定的应用价值。

On the basis of introducing the functions of Instrument Control Toolbox, the communication process between computer and the measurement equipment was designed through GPIB interface in the environment of MATLAB, and the plans of software and hardware of data transmission were also given in this paper. Take function signal generator for instance, the methods of controlhng instruments and data acquisition were studied and part of MATLAB programs were given, The experiment results showed that this method had the merit of programming easily, the powerful data processing, and had some values of application.
