</p><p>1、內(nèi)置高性能工業(yè)控制計(jì)算機(jī)</p><p>本裝置采用高性能工控機(jī)作為控制計(jì)算機(jī)，配置1G內(nèi)存8G硬盤，預(yù)裝Windows XP操作系統(tǒng)，面板帶有8.4″800*600分辨率TFT真彩LCD顯示器,電阻觸摸屏，不用外接鍵盤和鼠標(biāo)就可直接使用，裝置面板配有四個(gè)USB接口，可方便地進(jìn)行數(shù)據(jù)存取、數(shù)據(jù)通信和軟件升級(jí)等。</p><p> </p><p>2、 DSP數(shù)字信號(hào)處理系統(tǒng)</p><p>采用6000系列DSP控制器作為核心，F(xiàn)PGA可編程邏輯器件輸出波形，由于采用的是DDS硬件輸出波形的技術(shù)，使波形頻率和相位精度相當(dāng)高，同時(shí)，該系統(tǒng)與工控機(jī)通訊直接采用USB2.0接口，使得數(shù)據(jù)通訊穩(wěn)定可靠。</p><p> </p><p>3、 D/A和A/D轉(zhuǎn)換</p><p>采用高精度D/A轉(zhuǎn)換器，同時(shí)采用有源低通濾波器，使輸出波形平滑，幅頻特性優(yōu)良。同時(shí)控制系統(tǒng)還保留了12路12位A/D轉(zhuǎn)換電路，可實(shí)時(shí)采集12路模擬量的輸出波形并通過軟件在屏幕上顯示實(shí)際輸出的波形，幅值和相位。</p><p> </p><p>4、高精度線性電壓，電流功率放大器</p><p>電流，電壓采用高性能線性放大器直接耦合輸出方式，使電流，電壓源可直接輸出交流和直流波形，并可通過軟件計(jì)算輸出各種如方波、各次諧波疊加的組合波形，故障暫態(tài)波形等，可以較好地模擬各種短路故障時(shí)的電流，電壓特征。功放電路采用進(jìn)口大功率高保真模塊式功率器件作功率輸出級(jí)，結(jié)合精心合理設(shè)計(jì)的散熱結(jié)構(gòu)，具有足夠大的功率冗余和熱容量，功放電路具有完備的過熱、過流、過壓及短路保護(hù)，電流回路允許開路，不會(huì)損壞裝置。面板有電流開路指示燈，以方便用戶檢查接線正確與否。開路亮紅燈。大電流*采用*的硬件，*電路克服了傳統(tǒng)的軟件*的缺點(diǎn)，大電流使用更安全更可靠。當(dāng)*電路啟動(dòng)時(shí)，面板上亮綠燈。同時(shí)面板還有電壓過載或短路指示燈，當(dāng)電壓回路（在有輸出情況下）發(fā)生短路時(shí)，該指示燈發(fā)亮。</p><p> </p><p>5、開入量、開出量</p><p>裝置共有開入量8對(duì)，開出量4對(duì)。</p><p>開入、開出量都由光電隔離器和24V直流繼電器組成，其工作電源為獨(dú)立的24V工作電源。所以在COM端與開入量之間有110V的直流電壓。</p><p> </p><p>6、獨(dú)立的直流電源輸出</p><p> </p><p>裝置配有兩路110V直流電源電壓輸出，頭尾相接組成+110V、0V、-110V三個(gè)端子輸出，只能作保護(hù)裝置的工作電源，不能作直流操作電源使用。+110V、-110V兩端子裝在側(cè)面板上，這樣可輸出220V直流電壓。</p> </div> <link rel="stylesheet" type="text/css"
