【正文】 通過一個工業(yè)實例，這個特殊DAS的發(fā)展證明了一個通用系統(tǒng)的概念模型對于開發(fā)一個特定系統(tǒng)的有用性。我們的通用DAS概念模型在DAS設(shè)備的設(shè)計中發(fā)揮了重要作用。最后，我們分析了設(shè)備環(huán)境下的觀測和監(jiān)測報告。 （iii）能夠定義自定義和預(yù)定義的列車數(shù)據(jù)集。該系統(tǒng)的要求之一是能夠使用預(yù)定義的數(shù)據(jù)集來記錄特定狀態(tài)監(jiān)測報告。我們分析了設(shè)備環(huán)境下的設(shè)備項目包。為了驗證這個假設(shè)，我們基于我們的通用DAS概念模型開發(fā)了鐵路設(shè)備的DAS。好的、成本低的數(shù)據(jù)電子自動記錄儀有合適的通道數(shù)(2060通 道) 和掃描速率相對低但對于多數(shù)工程師的普遍應(yīng)用已足夠。 前端運轉(zhuǎn)的效率是非常高的, 能與速度和精度與最好的單機儀器匹敵。此外,因為數(shù)據(jù)電子自動記錄儀的監(jiān)測精度 , 多量且平均閱讀沒有必要,就像它們經(jīng)常在 PC 記插件卡片一樣。大多數(shù)數(shù)據(jù)電子自動記錄儀可設(shè)計為柔性和簡單的組態(tài)和操作 , 而且經(jīng)由電池包裹或其它方法,多數(shù)提供遠程位置的操作選項。 內(nèi)設(shè)智能數(shù)據(jù)電子自動記錄儀幫助你設(shè)定測量周期和具體指定每個通道的參數(shù)。使用數(shù)據(jù)電子自動記錄儀的一個好處就是他們的內(nèi)部監(jiān)測信號。數(shù)據(jù)電子自動記錄儀是典型的單機儀器,一旦配備它們 , 就能測 量、記錄和顯示數(shù)據(jù)而不需要操作員或計算機參與。這些插件卡片也測量一定范圍的電壓。因為卡片 本質(zhì)上是計算機的一部分, 建立測試是容易的。外部的 PC 機通常處理數(shù)據(jù)采集和分析。一些 benchtop DMMs 提供可選擇的掃描能力。在多通道內(nèi)較長時間的監(jiān)控,記錄儀能發(fā)揮很好的作用,除此之外,它們的價值得到限制。 他 們提供數(shù)據(jù)的長備紙記錄 , 因為數(shù)據(jù)是圖解的格式 , 他們易于現(xiàn)場采集數(shù)據(jù)。精度取決于謄寫器的水平, 并且你可能需要自己動手依比例輸入。而你所需要的就是捕捉到多路數(shù)字信息 (DMM ),然后開始用手記錄數(shù)據(jù)。今天的大學(xué)學(xué)生很可能在 PC 機上自動處理和分析數(shù)據(jù),有很多 種可供你選擇的方法去采集數(shù)據(jù)。設(shè)備從 簡單的存儲器發(fā)展到復(fù)雜的電腦系統(tǒng)。 and training item data sets, training custom data Sets and trains predefined data sets, which are device project data sets, custom data sets, and specialized sets of predefined data sets.Finally, we analyzed the observations and monitoring reports in the equipment environment. The system39。t detect small changes in the input signal. In addition, the electronic environment within the PC is often susceptible to noise, high clock rates, and bus noise. The electronic contacts limit the accuracy of the PC card. These plugin cards also measure a range of voltages. To measure other input signals, such as voltage, temperature, and resistance, you may need some external signal monitoring devices. Other considerations include plex calibrations and overall system costs, especially if you need to purchase additional signal monitoring devices or adapt the PC card to the card. Take this into account. If your needs change within the capabilities and limitations of the card, the PC plugin card provides an attractive method for data collection.Data electronic recorders are typical standalone instruments that, once equipped with them, enable the measurement, recording, and display of data without the involvement of an operator or puter. They can handle multiple signal inputs, sometimes up to 120 channels. Accuracy rivals unrivalled desktop DMMs because it operates within a 22 word, percent accuracy range. Some data electronic automatic recorders have the ability to measure proportionally, the inspection result is not limited by the user39。數(shù)據(jù)采集外文文獻翻譯 (含：英文原文及中文譯文) 文獻出處：Txomin Nieva.

In the simplest form, a technician logging the temperature of an oven on a piece of paper is performing data acquisition. As technology has progressed, this type of process has been simplified and made more accurate, versatile, and reliable through electronic equipment. Equipment ranges from simple recorders to sophisticated puter systems. Data acquisition products serve as a focal point in a system, t
