　　機(ji)(ji)車(che)(che)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)機(ji)(ji)技(ji)術(shu)(shu)是電(dian)(dian)力、內(nei)燃機(ji)(ji)車(che)(che)核心技(ji)術(shu)(shu)之一，作為一種自(zi)主(zhu)(zhu)研發(fa)、完全擁有(you)知識產權的新型(xing)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)機(ji)(ji)， DK-2型(xing)機(ji)(ji)車(che)(che)電(dian)(dian)空制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)機(ji)(ji)具備完善的微機(ji)(ji)模(mo)擬(ni)控制(zhi)(zhi)(zhi)(zhi)(zhi)、網(wang)絡通(tong)(tong)訊、故障(zhang)智能(neng)(neng)診斷(duan)等(deng)信息(xi)化(hua)功(gong)能(neng)(neng)，它采用微機(ji)(ji)模(mo)擬(ni)控制(zhi)(zhi)(zhi)(zhi)(zhi)技(ji)術(shu)(shu)，能(neng)(neng)實現(xian)列(lie)(lie)車(che)(che)自(zi)動(dong)(dong)(dong)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)與機(ji)(ji)車(che)(che)單(dan)獨制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)、以及空電(dian)(dian)聯(lian)(lian)合制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)、斷(duan)鉤保(bao)護、列(lie)(lie)車(che)(che)充風流量(liang)檢測(ce)、制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)重(zhong)聯(lian)(lian)、列(lie)(lie)車(che)(che)電(dian)(dian)空制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)、列(lie)(lie)車(che)(che)速度監控配合等(deng)功(gong)能(neng)(neng)，具備單(dan)機(ji)(ji)自(zi)檢、故障(zhang)診斷(duan)、數據(ju)記錄與存(cun)儲等(deng)智能(neng)(neng)化(hua)、信息(xi)化(hua)功(gong)能(neng)(neng)，具備MVB、CAN等(deng)網(wang)絡通(tong)(tong)訊接口(kou)，可通(tong)(tong)過(guo)網(wang)絡實現(xian)遠端(duan)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)重(zhong)聯(lian)(lian)控制(zhi)(zhi)(zhi)(zhi)(zhi)，適應現(xian)代機(ji)(ji)車(che)(che)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)機(ji)(ji)信息(xi)化(hua)以及網(wang)絡控制(zhi)(zhi)(zhi)(zhi)(zhi)的發(fa)展要求。DK-2制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)機(ji)(ji)有(you)5項(xiang)主(zhu)(zhu)要技(ji)術(shu)(shu)創新點在(zai)國內(nei)機(ji)(ji)車(che)(che)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)機(ji)(ji)中均(jun)屬(shu)首次采用，解(jie)決了(le)機(ji)(ji)車(che)(che)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)機(ji)(ji)的多項(xiang)關鍵技(ji)術(shu)(shu)，填補了(le)國內(nei)機(ji)(ji)車(che)(che)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)機(ji)(ji)多項(xiang)技(ji)術(shu)(shu)空白，突破了(le)機(ji)(ji)車(che)(che)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)機(ji)(ji)自(zi)主(zhu)(zhu)研發(fa)的技(ji)術(shu)(shu)瓶頸，使我國機(ji)(ji)車(che)(che)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)機(ji)(ji)的技(ji)術(shu)(shu)水(shui)平(ping)上升了(le)一個臺階。

　　DK-2制(zhi)動(dong)(dong)(dong)機完全能滿(man)足電(dian)力、內(nei)燃機車對機車制(zhi)動(dong)(dong)(dong)機的(de)(de)操縱、控(kong)制(zhi)和安(an)全性能的(de)(de)要(yao)求，可替代(dai)目(mu)前占領我國機車制(zhi)動(dong)(dong)(dong)機市場的(de)(de)進口產品，降低機車制(zhi)動(dong)(dong)(dong)機采(cai)購成(cheng)本(ben)，減少對進口設(she)備(bei)的(de)(de)依賴(lai)性，符合當代(dai)中國鐵(tie)路發展要(yao)求。

　　2007年(nian)，DK-2制動機(ji)在(zai)神華(hua)集(ji)(ji)團朔黃鐵路(lu)公司成功實現(xian)了首臺套樣機(ji)裝(zhuang)車運(yun)行考核，隨后(hou)實現(xian)小批量裝(zhuang)車運(yun)行。2009年(nian)開始在(zai)神華(hua)集(ji)(ji)團神朔公司再次實現(xian)了12臺套DK-2制動機(ji)的裝(zhuang)車改造。

　　據來自南車(che)株機公司的消息，今年(nian)，DK-2制(zhi)動機將(jiang)在出口中(zhong)東的TM3電力機車(che)上裝(zhuang)車(che)應用，實現進入國際市場(chang)的突(tu)破。
