Abstract Multiple parameters generating plant,could simulate a variety of physical parameters ,The research of a variety of physical parameter measurement is very beneficial. Virtual instrument is based on the computer,which is different from traditional instruments and have good ability of human-computer interaction,using virtual instrument could build different systems according to actual demand.
This paper is based on the LABVIEW graphical programming multi-parameter data acquisition system, the program implement the acceleration, impact force and pressure signal in real time measurement through the modular programming. and research some Processing method of impact signal. We could read data and the eigenvalue of impact signal from the screen directly.
Multi-parameter data acquisition system based on LABVIEW, with functions of data acquisition, analysis, storage and so on, has good stability and flexibility and can realize the measurement task.
