【摘要】：随着大容量存储技术及三维波形映射、显示技术在时域测量领域的应用,大大提高了数字示波器对异常信号的捕获及观察能力。但在现有存储映射技术运用中要么在三维映射之后丢失原始波形数据,要么在深存储下捕获率低下;在显示技术运用中不能根据用户的需求调整显示方式,显示方法单一,不利于对异常信号的观察。本文针对上述存储映射问题综合利用单幅采集单幅映射与分段存储集中映射波形三维成像技术实现深存储下的高捕获率与波形定量分析功能;针对上述显示问题利用波形亮度调节及校正技术实现对波形图像细节更加直观、有效的观察和分析。本课题在民营企业合作项目的基础上对分段存储集中映射技术、波形亮度调节和校正技术等存储映射及显示技术进行工程实际成果转化。该项目在实现上述功能的同时达到并超过项目所要求的500MHz模拟带宽、4GSPS实时采样率、单通道最大存储深度256Mpts和200000 wfms/s波形捕获率等各项技术指标,为进一步提升系统性能和完善系统功能打下了基础。本文将主要按如下顺序阐述:1、对现有两种主要波形存储映射三维成像技术分别进行分析和理论论证;对三维波形显示方法进行深入分析和理论论证;得出本设计中数字三维示波器的系统整体方案;2、波形存储映射系统设计,其中包括大容量存储器设计,波形分段存储集中映射功能设计及波形普通存储三维映射功能设计;3、三维波形显示系统设计,其中包括亮度调节技术的实现、并行映射矢量显示的实现及三维视窗扩展的实现;4、最后完成存储映射及显示技术的各功能模块调试及优化并提出下一步研究计划及展望。
[Abstract]:With the application of large capacity storage and 3D waveform mapping and display technology in time domain measurement, the ability of digital oscilloscope to capture and observe abnormal signals is greatly improved. However, in the application of the existing storage mapping technology, either the original waveform data is lost after 3D mapping, or the capture rate is low in deep storage. In the application of display technology, the display mode can not be adjusted according to the needs of users, and the display method is single. It is not good for the observation of abnormal signals. In order to solve the above storage mapping problem, this paper synthetically uses the technique of single acquisition and single amplitude mapping and piecewise storage centralized mapping waveform 3D imaging to realize the function of high capture rate and quantitative analysis of waveform under deep storage. In view of the above problems, the waveform brightness adjustment and correction technology is used to realize more visual and effective observation and analysis of the waveform image details. On the basis of the private enterprise cooperation project, this paper transforms the storage mapping and display technology such as segmented storage centralized mapping technology, waveform brightness adjustment and correction technology into practical engineering achievements. At the same time, the project achieves and exceeds the 500MHz analog bandwidth 4GSPS real-time sampling rate, single channel maximum storage depth 256Mpts and 200000 wfms/s waveform capture rate and so on. It lays the foundation for further improving the system performance and improving the system function. In this paper, according to the order described in the following order: 1, the existing two main waveform storage mapping three-dimensional imaging technology are analyzed and theoretical demonstration, three-dimensional waveform display method in-depth analysis and theoretical proof; The whole system scheme of digital 3D oscilloscope in this design is obtained. The waveform storage and mapping system is designed, including the design of large capacity memory. The function design of waveform segmented storage centralized mapping and waveform general storage 3D mapping design, 3D waveform display system design, including the realization of luminance adjustment technology, The realization of parallel mapping vector display and the implementation of 3D window extension. Finally, the debugging and optimization of each functional module of storage mapping and display technology are completed, and the next research plan and prospect are put forward.
