The Design of the Multifunctional Calibrated Program of Computer Based On LabWindows/CVI

摘要

In the realm of measurement, any of the test system of physics signal is composed of the sensor, amplifier, A/D conversion board and computer. Before using, we should adopt the homologous calibrated method; calculate all of the functional parameters of the test system according to the result of the calibration; conform the coefficient of data proceeding of the test system; the condition of the system should work in etc. In the last, one calibrated program calibrates one signal only, but the method introduced in the paper can calibrate several signals, such as pressure, force, temperature, acceleration, displacement etc. The Multifunctional Calibrated Program is designed with LabWindows/CVI, and it is very flexible and convenience to use. This paper emphasizes on the principle of multi-parameter calibrated program of the computer data acquisition, the method of the program design, the method of data proceeding, the way to extend the calibrated program. It provides the reference for multifunction of calibrated program of test system.
