| Abstract: | Physical experiments require acquisition of data and recording of experimental phenomena to facilitate the detailed analysis, a video and data synchronous acquisition system is presented in this paper, using the webcam capture live video, experiment data acquisition card which is based on ARM Cortex-M core chip of STM32F103RBT6. Video and data are transferred to the computers by TCP protocol through ethernet. Data visualization and data analysis are programmed by the software called LabVIEW. Video and data linkage and analysis are based on time indexing. The retrieval of detailed experimental video and data waveforms are based on data change points and indices of the key points in experiments. The system provides a more comprehensive, complete and accurate basis for experimental analysis, improving the efficiency of experimental analysis. |
