There are many ways you can choose to collect data. The choice of which method to use depends on many factors, including the plexity of the task, the speed and accuracy you need, the evidence you want, and more. Whether simple or plex, the data acquisition system can operate and play its role.The old way of using pencils and papers is still feasible for some situations, and it is cheap, easy to obtain, quick and easy to start. All you need is to capture multiple channels of digital information (DMM) and start recording data by hand.Unfortunately, this method is prone to errors, slower acquisition of data, and requires too much human analysis. In addition, it can only collect data in a single channel。 舉 例來(lái)說(shuō) , 在 40 年以前 , 在一個(gè)著名的學(xué)院實(shí)驗(yàn)室中 , 為追蹤用青銅做的坩堝中的溫度上升情況的裝置是由熱電偶、繼電器、查詢臺(tái)、一捆紙和一支鉛筆。 你能很清楚地感覺(jué)到與筆只有小的改變。此外,PC 機(jī)內(nèi)的電子環(huán)境經(jīng)常很容易發(fā)出噪聲、 產(chǎn)生高速率的時(shí)鐘和總線噪聲,電子接觸面限制 PC 機(jī)插件卡片的精度。與 PC 機(jī)連接容易將數(shù)據(jù)傳送到電腦進(jìn)行進(jìn)一步的分析。因此，使用通用系統(tǒng)的概念模型將節(jié)省時(shí)間并降低特定系統(tǒng)開(kāi)發(fā)的成本。以及訓(xùn)練項(xiàng)目數(shù)據(jù)集，訓(xùn)練自定義數(shù)據(jù)集和訓(xùn)練預(yù)定義數(shù)據(jù)集，它們分別是設(shè)備項(xiàng)目數(shù)據(jù)集，自定義數(shù)據(jù)集和預(yù)定義數(shù)據(jù)集的專業(yè)化。我們使用這個(gè)模型來(lái)更好地組織將被系統(tǒng)組件使用的數(shù)據(jù)。根據(jù)這一分析，我們?cè)谙到y(tǒng)的概念模型中列出了一個(gè)三層次的物品層次。前端數(shù)據(jù)采集經(jīng)常做成模塊而且是典型地與 PC 機(jī)或控制器連 接。它們能夠處理多 信號(hào)輸入,有時(shí)可達(dá) 120通道。儀器的背面有一 個(gè)槽孔接收一張?jiān)谳^多輸入時(shí)能多重發(fā)訊的掃描儀卡片, 通常是 8到10通道的mux 。不幸的是這種方法容易發(fā)生錯(cuò)誤、 采集數(shù)據(jù)變慢和需要太多的人工分析。s definition, and the output is a control signal.One of the advantages of using data electronic loggers is their internal monitoring signals. Most can directly measure several different input signals without the need for additional signal monitoring devices. One channel can monitor thermocouples, RTDs, and voltages.Thermocouples provide valuable pensation for accurate temperature measurements. They are typically equipped with multichannel cards. Builtin intelligent electronic data recorder helps you set the measurement period and specify the parameters for each channel. Once you set it all up, the data electronic recorder will behave like an unbeatable device. The data they store is distributed in memory and can hold 500,000 or more readings.Connecting to a PC makes it easy to transfer data to a puter for further analysis. Most data electronic recorders can be designed to be flexible and simple to configure and operate, and most provide remote location operation options via battery packs or other methods. Thanks to the A/D conversion technology, certain data electronic recorders have a lower reading rate, especially when pared with PC plugin cards. However, a reading rate of 250 per second is relatively rare. Keep in mind that many of the phenomena that are being measured are physical in nature, such as temperature, pressure, and flow, and there are generally fewer changes. In addition, because of the monitoring accuracy of the data electron loggers, a large amount of average reading is not necessary, just as they are often stuck on PC plugin cards.Frontend data acquisition is often done as a module and is typically connected to a PC
