37、若泄露(lu)(lu)電(dian)(dian)流變(bian)化(hua)率差值大于泄露(lu)(lu)電(dian)(dian)流變(bian)化(hua)率閾值，則判定(ding)當(dang)前電(dian)(dian)纜段存(cun)在(zai)故障缺(que)陷(xian)；

38、若(ruo)泄露電(dian)流(liu)變化(hua)率差(cha)值(zhi)小于等于泄露電(dian)流(liu)變化(hua)率閾(yu)值(zhi)，則(ze)判定當前電(dian)纜段所在的電(dian)纜為故(gu)障狀態，并發(fa)送故(gu)障警報。

39、本(ben)方案(an)中，當電(dian)(dian)(dian)纜段存(cun)在(zai)隱患時(shi)，電(dian)(dian)(dian)流(liu)(liu)(liu)通過(guo)所在(zai)位置時(shi)產生的(de)(de)泄(xie)(xie)露(lu)(lu)(lu)電(dian)(dian)(dian)流(liu)(liu)(liu)大(da)(da)；當調整電(dian)(dian)(dian)流(liu)(liu)(liu)的(de)(de)大(da)(da)小(xiao)時(shi)，存(cun)在(zai)隱患的(de)(de)位置的(de)(de)泄(xie)(xie)露(lu)(lu)(lu)電(dian)(dian)(dian)流(liu)(liu)(liu)變(bian)(bian)化量往往會比正常(chang)工作的(de)(de)電(dian)(dian)(dian)纜段的(de)(de)泄(xie)(xie)露(lu)(lu)(lu)電(dian)(dian)(dian)流(liu)(liu)(liu)變(bian)(bian)化量要大(da)(da)，因此，判斷一(yi)個電(dian)(dian)(dian)流(liu)(liu)(liu)異常(chang)點是否(fou)是環(huan)境(jing)影響(xiang)(xiang)(xiang)導致(zhi)泄(xie)(xie)露(lu)(lu)(lu)電(dian)(dian)(dian)流(liu)(liu)(liu)增大(da)(da)還是電(dian)(dian)(dian)纜段本(ben)身出現(xian)缺(que)陷導致(zhi)的(de)(de)泄(xie)(xie)露(lu)(lu)(lu)電(dian)(dian)(dian)流(liu)(liu)(liu)增大(da)(da)，只(zhi)需要調整通過(guo)電(dian)(dian)(dian)流(liu)(liu)(liu)的(de)(de)大(da)(da)小(xiao)，當電(dian)(dian)(dian)流(liu)(liu)(liu)異常(chang)點的(de)(de)泄(xie)(xie)露(lu)(lu)(lu)電(dian)(dian)(dian)流(liu)(liu)(liu)變(bian)(bian)化高于正常(chang)工作的(de)(de)電(dian)(dian)(dian)纜段的(de)(de)泄(xie)(xie)露(lu)(lu)(lu)電(dian)(dian)(dian)流(liu)(liu)(liu)變(bian)(bian)化時(shi)且超過(guo)一(yi)定的(de)(de)允許(xu)誤差，則說明所述電(dian)(dian)(dian)流(liu)(liu)(liu)異常(chang)點對(dui)應的(de)(de)電(dian)(dian)(dian)纜段出現(xian)了(le)(le)缺(que)陷，通過(guo)這種方式簡單(dan)的(de)(de)體現(xian)了(le)(le)電(dian)(dian)(dian)纜是否(fou)出現(xian)故障，排(pai)除(chu)了(le)(le)受到外(wai)部環(huan)境(jing)影響(xiang)(xiang)(xiang)對(dui)電(dian)(dian)(dian)纜泄(xie)(xie)露(lu)(lu)(lu)電(dian)(dian)(dian)流(liu)(liu)(liu)的(de)(de)影響(xiang)(xiang)(xiang)，提高了(le)(le)電(dian)(dian)(dian)纜故障排(pai)查的(de)(de)效(xiao)率和準確度(du)。

40、第二方面，本發(fa)明實施例中提供的(de)一種(zhong)技(ji)術(shu)方案(an)是：一種(zhong)電纜(lan)(lan)(lan)故障檢測系統，包(bao)括：數據采集模塊：獲取每(mei)一個電纜(lan)(lan)(lan)段(duan)(duan)的(de)泄露電流信(xin)號(hao)，當(dang)電纜(lan)(lan)(lan)段(duan)(duan)的(de)泄露電流信(xin)號(hao)超過設定閾值時(shi)，獲取對應(ying)電纜(lan)(lan)(lan)段(duan)(duan)的(de)狀態信(xin)息(xi)，并根(gen)據安裝在電纜(lan)(lan)(lan)段(duan)(duan)上的(de)順(shun)序對檢測裝置(zhi)進(jin)行(xing)編碼(ma)；

41、拼(pin)接(jie)模塊：根(gen)據檢(jian)測(ce)(ce)裝置(zhi)(zhi)的編(bian)碼對電纜(lan)(lan)段的狀態(tai)信(xin)(xin)息(xi)(xi)進行順次拼(pin)接(jie)得到目(mu)標(biao)電纜(lan)(lan)狀態(tai)信(xin)(xin)息(xi)(xi)；獲取模塊：對檢(jian)測(ce)(ce)裝置(zhi)(zhi)編(bian)碼信(xin)(xin)息(xi)(xi)進行拆分，將(jiang)拆分后的檢(jian)測(ce)(ce)裝置(zhi)(zhi)編(bian)碼信(xin)(xin)息(xi)(xi)發送至云端(duan)，云端(duan)將(jiang)拆分后的檢(jian)測(ce)(ce)裝置(zhi)(zhi)編(bian)碼信(xin)(xin)息(xi)(xi)重組得到目(mu)標(biao)檢(jian)測(ce)(ce)裝置(zhi)(zhi)編(bian)碼信(xin)(xin)息(xi)(xi)，根(gen)據目(mu)標(biao)檢(jian)測(ce)(ce)裝置(zhi)(zhi)編(bian)碼信(xin)(xin)息(xi)(xi)獲取目(mu)標(biao)電纜(lan)(lan)檢(jian)測(ce)(ce)信(xin)(xin)息(xi)(xi)；

42、判定模塊：根據設定的安全泄露(lu)電(dian)流閾(yu)值(zhi)(zhi)提取目標(biao)電(dian)纜(lan)段，云端(duan)通(tong)過臨值(zhi)(zhi)判斷機制對目標(biao)電(dian)纜(lan)段進行狀態判斷，結(jie)合(he)目標(biao)電(dian)纜(lan)檢測(ce)信(xin)息輸出初(chu)步判定結(jie)果(guo)；

43、確定(ding)模塊(kuai)：利用(yong)深度神經(jing)網絡(luo)算(suan)法建立(li)電纜內部電流(liu)變化(hua)與電纜泄露電流(liu)值變化(hua)之(zhi)間的(de)耦合關系并結合初步(bu)判定(ding)結果(guo)判段目標電纜是(shi)否(fou)存在故障。

44、本方案中，由于電(dian)纜(lan)(lan)(lan)(lan)鋪設的(de)(de)(de)規(gui)模(mo)較大(da)，想要對(dui)(dui)整體(ti)(ti)電(dian)纜(lan)(lan)(lan)(lan)之間進(jin)(jin)行(xing)(xing)檢(jian)測(ce)(ce)(ce)(ce)(ce)(ce)難(nan)度較大(da)，因此(ci)在(zai)電(dian)纜(lan)(lan)(lan)(lan)上(shang)安裝(zhuang)(zhuang)(zhuang)(zhuang)了(le)若干個(ge)(ge)(ge)檢(jian)測(ce)(ce)(ce)(ce)(ce)(ce)裝(zhuang)(zhuang)(zhuang)(zhuang)置(zhi)(zhi)(zhi)，檢(jian)測(ce)(ce)(ce)(ce)(ce)(ce)裝(zhuang)(zhuang)(zhuang)(zhuang)置(zhi)(zhi)(zhi)中設有數據(ju)采(cai)集(ji)模(mo)塊(kuai)，這些檢(jian)測(ce)(ce)(ce)(ce)(ce)(ce)裝(zhuang)(zhuang)(zhuang)(zhuang)置(zhi)(zhi)(zhi)分別檢(jian)測(ce)(ce)(ce)(ce)(ce)(ce)自(zi)己(ji)所安裝(zhuang)(zhuang)(zhuang)(zhuang)的(de)(de)(de)一段電(dian)纜(lan)(lan)(lan)(lan)的(de)(de)(de)狀(zhuang)態信(xin)(xin)息，通(tong)過(guo)對(dui)(dui)這些檢(jian)測(ce)(ce)(ce)(ce)(ce)(ce)裝(zhuang)(zhuang)(zhuang)(zhuang)置(zhi)(zhi)(zhi)進(jin)(jin)行(xing)(xing)編碼(ma)，檢(jian)測(ce)(ce)(ce)(ce)(ce)(ce)裝(zhuang)(zhuang)(zhuang)(zhuang)置(zhi)(zhi)(zhi)存(cun)儲有鄰接(jie)電(dian)纜(lan)(lan)(lan)(lan)的(de)(de)(de)裝(zhuang)(zhuang)(zhuang)(zhuang)置(zhi)(zhi)(zhi)編碼(ma)信(xin)(xin)息并(bing)通(tong)過(guo)拆分模(mo)塊(kuai)對(dui)(dui)裝(zhuang)(zhuang)(zhuang)(zhuang)置(zhi)(zhi)(zhi)編碼(ma)信(xin)(xin)息進(jin)(jin)行(xing)(xing)拆分，可(ke)以提高信(xin)(xin)息傳輸的(de)(de)(de)安全性；通(tong)過(guo)拼(pin)接(jie)模(mo)塊(kuai)對(dui)(dui)各個(ge)(ge)(ge)檢(jian)測(ce)(ce)(ce)(ce)(ce)(ce)裝(zhuang)(zhuang)(zhuang)(zhuang)置(zhi)(zhi)(zhi)獲取電(dian)纜(lan)(lan)(lan)(lan)檢(jian)測(ce)(ce)(ce)(ce)(ce)(ce)信(xin)(xin)息順次(ci)拼(pin)接(jie)形成整體(ti)(ti)電(dian)纜(lan)(lan)(lan)(lan)的(de)(de)(de)檢(jian)測(ce)(ce)(ce)(ce)(ce)(ce)信(xin)(xin)息并(bing)同(tong)步(bu)至管理平臺或(huo)/和移動(dong)端(duan)，通(tong)過(guo)判定模(mo)塊(kuai)和確定模(mo)塊(kuai)對(dui)(dui)電(dian)纜(lan)(lan)(lan)(lan)檢(jian)測(ce)(ce)(ce)(ce)(ce)(ce)信(xin)(xin)息進(jin)(jin)行(xing)(xing)判定并(bing)得出結論，當檢(jian)測(ce)(ce)(ce)(ce)(ce)(ce)到(dao)電(dian)纜(lan)(lan)(lan)(lan)故障時，則發送報(bao)警(jing)信(xin)(xin)號(hao)并(bing)對(dui)(dui)電(dian)纜(lan)(lan)(lan)(lan)進(jin)(jin)行(xing)(xing)異(yi)常定位(wei)，并(bing)且每個(ge)(ge)(ge)檢(jian)測(ce)(ce)(ce)(ce)(ce)(ce)裝(zhuang)(zhuang)(zhuang)(zhuang)置(zhi)(zhi)(zhi)都可(ke)以根據(ju)編碼(ma)信(xin)(xin)息并(bing)根據(ju)裝(zhuang)(zhuang)(zhuang)(zhuang)置(zhi)(zhi)(zhi)編碼(ma)信(xin)(xin)息的(de)(de)(de)順位(wei)進(jin)(jin)行(xing)(xing)通(tong)信(xin)(xin)，在(zai)其(qi)中一個(ge)(ge)(ge)檢(jian)測(ce)(ce)(ce)(ce)(ce)(ce)裝(zhuang)(zhuang)(zhuang)(zhuang)置(zhi)(zhi)(zhi)無(wu)法通(tong)信(xin)(xin)時，其(qi)周圍(wei)的(de)(de)(de)檢(jian)測(ce)(ce)(ce)(ce)(ce)(ce)裝(zhuang)(zhuang)(zhuang)(zhuang)置(zhi)(zhi)(zhi)均可(ke)接(jie)收到(dao)信(xin)(xin)號(hao)并(bing)將信(xin)(xin)號(hao)發送給(gei)管理平臺或(huo)/和移動(dong)端(duan)，通(tong)過(guo)這種方式顯著降低了(le)對(dui)(dui)大(da)規(gui)模(mo)鋪設電(dian)纜(lan)(lan)(lan)(lan)的(de)(de)(de)故障檢(jian)測(ce)(ce)(ce)(ce)(ce)(ce)的(de)(de)(de)難(nan)度，并(bing)且提升了(le)故障檢(jian)測(ce)(ce)(ce)(ce)(ce)(ce)時的(de)(de)(de)排(pai)查精度。
