| Abstract: | The paper deceloped control system for experiments of impact vibration, and designed the software of DAQ based on LabVIEW's multi-threads technical. The program realized the reverse control of the two three-channel magnet valves and collected the multi-channel analog signals by using PIO-821PGL multi-function card as the DAQ and DIO hardware. The paper used the serial port of computer to communicate with the PIC controller of laser target at the same time and collected the dates of laser target. After gaining all the necessary data, it shows them in the module of data analysis, and indicates the data of some time of sensors and laser target synchronously, and checks all the signals by FFT. |
