方案描(miao)述：斷(duan)(duan)路器(qi)主(zhu)要(yao)包括進行數據(ju)采(cai)集：輸(shu)(shu)入通(tong)道(dao)（如模擬量(liang)輸(shu)(shu)入變換與低(di)通(tong)濾波(bo)回路、采(cai)樣保(bao)持與多(duo)路轉換系統以及(ji)開關量(liang)輸(shu)(shu)入通(tong)道(dao)等(deng)(deng)）、進行數據(ju)處理及(ji)相(xiang)應判斷(duan)(duan)的數字(zi)核心部分（如CPU、存儲器(qi)、實時(shi)(shi)時(shi)(shi)鐘(zhong)、看門狗(gou)等(deng)(deng)）以及(ji)輸(shu)(shu)出通(tong)道(dao)（如開關量(liang)輸(shu)(shu)出通(tong)道(dao)等(deng)(deng)）。除此之外，還有人(ren)機接口（如鍵盤、顯示器(qi)及(ji)打(da)印機）。

供電方式：斷(duan)路(lu)器(qi)(qi)系統電(dian)(dian)源(yuan)解(jie)決方案(an)：一般給斷(duan)路(lu)器(qi)(qi)內部處(chu)理(li)器(qi)(qi)、存(cun)儲器(qi)(qi)、I/O模(mo)塊(kuai)、各種擴(kuo)展模(mo)塊(kuai)供電(dian)(dian)的電(dian)(dian)壓(ya)為(wei)5VDC，可(ke)通(tong)總線提供的24V總線電(dian)(dian)源(yuan)利用DCDC模(mo)塊(kuai)隔離變壓(ya)獲得。對(dui)于通(tong)信部分可(ke)以(yi)通(tong)過隔離電(dian)(dian)源(yuan)和(he)光耦隔離提高通(tong)信的可(ke)靠性。信號調理(li)模(mo)塊(kuai)的供電(dian)(dian)由(you)定壓(ya)穩壓(ya)系列產品提供穩定的低紋波直流電(dian)(dian)壓(ya)。

方案特(te)點：隔(ge)(ge)離(li)(li)變送(song)器(qi)模塊解決方案：信(xin)號(hao)調理的信(xin)號(hao)輸(shu)出為0-5V的電(dian)(dian)(dian)壓信(xin)號(hao)可以通過隔(ge)(ge)離(li)(li)變送(song)模塊隔(ge)(ge)離(li)(li)后送(song)給處理器(qi)0-5V電(dian)(dian)(dian)壓信(xin)號(hao)，經過多路(lu)開關轉換成可處理的數(shu)字信(xin)號(hao)。隔(ge)(ge)離(li)(li)變送(song)器(qi)供電(dian)(dian)(dian)可直(zhi)接(jie)由系統電(dian)(dian)(dian)源的24V電(dian)(dian)(dian)壓供電(dian)(dian)(dian)。
