| The system is studied by using the software, LabVIEW, and the hardware including PC, DAQ, sensor and amplifier. The computer controls parameter setting, the data acquisition, signal processing and saving and etc, which can meet the need of dynamic measurement.Firstly, simple introduction on virtual instrument and LabVIEW is made in the thesis. Secondly, the characteristic of recoil system is analyzed. Sensor measuring speed and displacement of recoil operated. Thirdly, special function of the data acquisition board is systematically analyzed. The method with software that can extend the special function of program controlled level is put forward. Fourthly, the function and the usage of every module are studied in detail as the sequence of parameter setting, data acquisition, filter, signal processing.The results of experiment prove the practicability and the accuracy of the system, which is easy to be developed by engineer for the good expansibility and high price performance ratio. |
