摘要：
A multichannel system was developed for vibration measurement and analysis based on LabVIEW , a popular workbench for virtual instruments to make measurement and analysis using computers. An external data acquisition box was used to sample the data with internal and external triggering, A/D conversion and first-in-first-out (FIFO) storage. The sampled data were transferred from the data acquisition box to the computer through the enhanced parallel port. The LabVIEW system then processed the data and sent out necessary control signals. The results show that the developed system can provide functions of vibration data sampling, storage, analysis and recall with high precision.
