指磁的耦合，在大功率變壓器、交流電機、強電流電網(wǎng)等的周圍空間都存在很強的交變磁場，而控制系統(tǒng)(檢測、變送、轉換、調節(jié)、計算、執(zhí)行、輔助、顯示等單元)線路形成的閉合回路處在這種變化的磁場中將被感應出電勢，使信號源與儀器儀表之間的連接導線、儀表內部的配線通過磁耦合在電路中形成干擾。這種電磁感應電勢與有用信號相串聯(lián)，當信號源與顯示儀表相距較遠時，干擾較為突出。此外，高頻率發(fā)生器、帶整流子的電機等設備，也會產生高頻率的干擾。

1.**初的智能儀表被稱為自動抄表系統(tǒng)（AMR），也是遠程自動抄表也成為了智能儀表**基本的功能。利用智能儀表的紅外線等通信功能，就能夠實現(xiàn)自動抄表。這樣就不需要工作人員前往現(xiàn)場進行人工抄表，提升了效率，也削減抄表業(yè)務的成本。此外，還能夠減少人為因素造成的失誤，抄表精度得到提升，也使得收益得到提升。之后雙向通信的遠程操作功能也增加進來，防止非法使用電力/燃氣等，因此智能儀表**初被能源行業(yè)應用和看好。 </p> <p> <br /> </p><p> 微電子技術和計算機技術的不斷發(fā)展，引起了儀表結構的根本性變革，以微型計算機（單片機）為主體，將計算機技術和檢測技術有機結合，組成新一代“智能化儀表”，在測量過程自動化、測量數(shù)據(jù)處理及功能多樣化方面與傳統(tǒng)儀表的常規(guī)測量電路相比較，取得了巨大進展。 </p> <p> 智能儀表不僅能解決傳統(tǒng)儀表不易或不能解決的問題，還能簡化儀表電路，提高儀表的可靠性，更容易實現(xiàn)高精度、高性能、多功能的目的。隨著科學技術的進一步發(fā)展，儀表的智能化程度將越來越高。智能儀表，不但能完成多種物理量的精確顯示，同時可以帶變送輸出、繼電器控制輸出、通訊、數(shù)據(jù)保持等多種功能。 </p> <p> 智能儀表和智能傳感器一般是用在現(xiàn)場總線系統(tǒng)中，這種儀表和傳感器內部嵌入的有通訊模塊和控制模塊，可以完成數(shù)據(jù)采集，數(shù)據(jù)處理和數(shù)據(jù)通訊功能,說白了就是在普通的儀表和傳感器上加了個單片機。 </p> <p> <br /> </p><div style="width:100%;text-align: center;"><img

指電的耦合，靜電感應是兩電場相互作用的結果。在相對的兩根導線中，如其一的電位發(fā)生變化，則由于導線間的電容變化使得另一導線的電位也發(fā)生變化，干擾源以電容性的耦合在回路中形成干擾。 </p> <p> 電勢 </p> <p> 附加熱電勢和化學電勢。由于不同金屬產生的熱電勢以及金屬腐蝕等產生的化學電勢，在電路回路中形成直流電氣干擾。 </p> <p> <p> 震動 </p> <p> 在強振動的環(huán)境中，導線由于在磁場中處于運動狀態(tài)而產生感應電勢，此干擾與信號相串聯(lián)，以串模干擾形式進入儀器儀表。 </p> 成都數(shù)字智能顯示儀表哪家專業(yè)</p><p style="text-indent:25px">成都數(shù)字智能顯示儀表哪家專業(yè)</p><p> 智能儀表的特點 </p> <p> 編輯 </p> <p> (1)精度高智能變送器具有較高的精度。利用內裝的微處理器，能夠實時測量出靜壓、溫度變化對檢測元件的影響，通過數(shù)據(jù)處理，對非線性進行校正，對滯后及復現(xiàn)性進行補償，使得輸出信號更精確。一般情況，精度為比較大量程的±0.1%，數(shù)字信號可達±0.075% </p> <p> (2)功能強 </p> <p> 智能變送器具有多種復雜的運算功能，依賴內部微處理器和存儲器，可以執(zhí)行開方、溫度壓力補償及各種復雜的運算。 </p> <p> (3)測量范圍寬 </p> <p> 普通變送器的量程比比較大為10:1，而智能變送器可達40:1或100:1，遷移量可達1900%和-200%，減少變送器的規(guī)格，增強通用性和互換性，給用戶帶來諸多方便。 </p> <p> (4)通信功能強 </p> <p> 智能變送器均可實現(xiàn)手操器進行操作，既可在現(xiàn)場將手操器插到變送器的相應插孔，也可以在控制室將手操器連接到變送器的信號線上，進行零點及量程的調校及變更。有的變送器具有模擬量和數(shù)字量兩種輸出方式(如HART協(xié)議)，為實現(xiàn)現(xiàn)場總線通訊奠定了基礎。成都數(shù)字智能顯示儀表哪家專業(yè)</p><p
