基于Labwindows／CVI测控软件的校准方法研究

摘要

介绍了在测控软件设计中用软件修正测量误差的方法，分析误差来源并建立数学模型。实验证明使用最小二乘算法来逼近校准曲线效果最好，通过软件修正测量误差使测量结果更精确，提高了测量仪器的测量精度。该项目的上位机软件以铁路应答器综合检测系统为背景，使用Labwindows／CVI作为开发平台。Labwindows／CVI是NI公司推出的具有强大功能的测控软件开发平台，完全可以满足项目要求。%It introduces the measurement error correction methods used in the monitoring and control software design. Analysis of error sources and Establish mathematical model. Experiments show that using the least squares algorithm to approximate the best calibration curve. Correcting Measurement errors with software to make more accurate measurements, Improve the accuracy of measuring instruments. The project＇s PC software to railway transponder integrated detection system for the background. Use Labwindows / CVI as a development platform. Labwindows / CVI is introduced NI measurement and control with powerful software development platform, fully meet the project requirements.
