[Abstract]:Data acquisition, storage and analysis unit is an important part of modern test system. Its main function is to complete real-time data storage, dynamic display and analysis and processing, and to view the status of the test process. It is very important to manage the experimental data. With the development of modern test system, it is necessary to realize the technology of high sampling rate, large capacity and multi-channel dynamic data acquisition and analysis. This paper summarizes the functional requirements and characteristics of the large capacity dynamic data acquisition and analysis program, and discusses the implementation methods and key technologies of each function in modules. According to the function, the program is divided into three modules: efficient storage module, dynamic display module and analysis and processing module. In order to meet the requirements of the project, this paper demonstrates the implementation of 16 channel data storage, display and analysis. On the basis of. Net Framework 4 framework, combined with the technical specifications of the system and the software and hardware platform based on the software and hardware, the mechanism of "producer and consumer" mode combined with multi-thread is adopted to realize the fast storage of the large capacity test data into the computer hard disk. Using the technology of double buffering and component, the dynamic display of multi-channel data is completed, and there are two ways to display the multi-channel data: single graph, single channel and single graph. Multi-thread method is used to process data storage, display, and achieve multi-task synchronization. Microsoft Visual 2010 (C #) is used to complete the design of each module of the program and the performance test of the key parts. Finally, after the test is completed, the software provides the operation of data analysis, data playback, data export and so on. The method of memory mapping file is used to realize the fast reading of the data on the hard disk. The verification experiment combining computer drawing with parallel programming is given, and the experimental results and reasons are analyzed. Through the software design of the large capacity dynamic test data acquisition and analysis system, the requirements of the test system are fulfilled, and the further improvement of the system is prospected.
