【摘要】：隨著大容量存儲技術(shù)及三維波形映射、顯示技術(shù)在時域測量領(lǐng)域的應(yīng)用,大大提高了數(shù)字示波器對異常信號的捕獲及觀察能力。但在現(xiàn)有存儲映射技術(shù)運用中要么在三維映射之后丟失原始波形數(shù)據(jù),要么在深存儲下捕獲率低下;在顯示技術(shù)運用中不能根據(jù)用戶的需求調(diào)整顯示方式,顯示方法單一,不利于對異常信號的觀察。本文針對上述存儲映射問題綜合利用單幅采集單幅映射與分段存儲集中映射波形三維成像技術(shù)實現(xiàn)深存儲下的高捕獲率與波形定量分析功能;針對上述顯示問題利用波形亮度調(diào)節(jié)及校正技術(shù)實現(xiàn)對波形圖像細(xì)節(jié)更加直觀、有效的觀察和分析。本課題在民營企業(yè)合作項目的基礎(chǔ)上對分段存儲集中映射技術(shù)、波形亮度調(diào)節(jié)和校正技術(shù)等存儲映射及顯示技術(shù)進行工程實際成果轉(zhuǎn)化。該項目在實現(xiàn)上述功能的同時達到并超過項目所要求的500MHz模擬帶寬、4GSPS實時采樣率、單通道最大存儲深度256Mpts和200000 wfms/s波形捕獲率等各項技術(shù)指標(biāo),為進一步提升系統(tǒng)性能和完善系統(tǒng)功能打下了基礎(chǔ)。本文將主要按如下順序闡述:1、對現(xiàn)有兩種主要波形存儲映射三維成像技術(shù)分別進行分析和理論論證;對三維波形顯示方法進行深入分析和理論論證;得出本設(shè)計中數(shù)字三維示波器的系統(tǒng)整體方案;2、波形存儲映射系統(tǒng)設(shè)計,其中包括大容量存儲器設(shè)計,波形分段存儲集中映射功能設(shè)計及波形普通存儲三維映射功能設(shè)計;3、三維波形顯示系統(tǒng)設(shè)計,其中包括亮度調(diào)節(jié)技術(shù)的實現(xiàn)、并行映射矢量顯示的實現(xiàn)及三維視窗擴展的實現(xiàn);4、最后完成存儲映射及顯示技術(shù)的各功能模塊調(diào)試及優(yōu)化并提出下一步研究計劃及展望。
[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.
