单参量或同性多参量的参数微机化数据采集器对电子工程师而言并不新鲜,但是,对于用同一个数据采集器进行非同性,例如:温度、压力、光学等多参量的测量则仍然是需要研究的问题。在同一个数据采集器进行多参量测量中,必需妥善地解决各参量的归一化、偏置、非线性校正及系统的自校等问题,在这方面,基于个人计算机的数据采集器将能大显身手,由于这种计算机具有强大的硬件和软件功能。
Single-parameter or multi-parameter parameters of the same parameter Microcomputer-based data acquisition for electronic engineers is not new, but for the same data acquisition for non-homology, such as: temperature, pressure, optical and other multi-parameter measurement is still Need to study the problem. In the same data collector for multi-parameter measurement, the normalization, offset, non-linear correction of the parameters and self-calibration of the system must be properly solved. In this respect, the personal computer-based data collector Show off because of the powerful hardware and software features of this computer.
