Data gathering system of test - bed of thrust bear 推力軸承試驗臺的數(shù)據(jù)采集系統(tǒng)
Portable general data gathering system 便攜式通用數(shù)據(jù)采集系統(tǒng)
Provide super - user support to the plant wide data gathering system 為工廠數(shù)據(jù)采集系統(tǒng)提供支持,包括系統(tǒng)顯示的所有控制點。
In addition , make out in detail the design on inner combination logic and time logic of fpga , including series - parallel conversion , data selector , counter , flip - latch , timer , encoder , etc . at one time , not only pursuit flow of the data gathering system is illuminated , but also make use of in reason and effectively inner ram resource of fpga and build it in ping - pong framework 另外,詳細(xì)的介紹了fpga內(nèi)部的組合邏輯和時序邏輯的設(shè)計方案,包括串并轉(zhuǎn)換、數(shù)據(jù)選擇器、計數(shù)器、鎖存器、定時器、譯碼器等。并闡述了數(shù)據(jù)采集系統(tǒng)的工作流程,而且合理有效地使用了fpga內(nèi)部的ram資源,將其構(gòu)建成乒乓式結(jié)構(gòu)。
The primary task of this thesis is how to design a set of data gathering system , which can track record original wave forms of sound signals , the moment that sound impulse range pass gate limits , the data on the orientations of vector water - sensor in the buoy and the data obtained by gps 本論文以整個系統(tǒng)的硬件設(shè)計為主要研究對象,主要任務(wù)是設(shè)計一套數(shù)據(jù)采集系統(tǒng),完成對聲信號的原始波形及聲脈沖幅度過門限時刻、浮標(biāo)上矢量水聽器的方位數(shù)據(jù)及gps數(shù)據(jù)的記錄。
