小的范圍內(nèi)變化,如果明顯某個(gè)同一品牌的不同GPS天線和同一品牌的其他GPS天線的R1或R2的電阻值有明顯不同,或者R1和R2的電阻值差異較大(應(yīng)該在同一數(shù)量級,那該GPS天線肯定有問題,更換該天線。比如R1和R2的電阻值為0或無窮大,說明GPS天線有短路或斷路故障。3檢查天饋部分各接口是否連接可靠,室外部分的防水是否良好。4檢查功分器是否接得太多,導(dǎo)致信號太弱?；蝠伨€長度超過120米,檢查有無干放重新設(shè)計(jì)GPS天饋系統(tǒng)。2、否則,檢查GPS串口狀態(tài)。通過ClkShow命令查看“STATUS”狀態(tài):查看iRs232Fd:17,STATUS:1,TYPE:Trimble,1pps:0STATUS:2,(串口通訊:0表示串口不通,2表示GPS正常了,1仍在通訊之中若STATUS等于0,表示串口不通,BCCS與GPS子卡不能通信,則檢查連接線纜,重新插拔BCCS,復(fù)位BCCS,或更換子卡,或更換BCCS槽位,或更換BCCS單板。ClkShow命令介紹見附件1.3GPS故障1.3.1排查方法簡述1、告警子碼為31-32:GPS天線連接開路或41-42:GPS天線連接短路,檢查GPS天饋系統(tǒng),具體可見1.2節(jié)“GPS狀態(tài)異?！辈糠帧?、告警子碼為11-12:與GPS模塊通信鏈路中斷,參考1.2節(jié)“GPS狀態(tài)異?！辈糠謱Υ诠收系奶幚矸椒ā?、告警子碼為1-2:GPS衛(wèi)星丟失告警或21-22:GPS的TRAIM告警(>50NS,按如下方法處理:1檢查GPS天線位置是否滿足120度的凈空要求。2檢查GPS是否受到干擾。3檢查GPS天饋系統(tǒng)。具體可見1.2節(jié)“GPS狀態(tài)異常”部分。1.3.2排查方法詳述告警子碼為1-2:GPS衛(wèi)星丟失告警或21-22:GPS的TRAIM告警(>50NS的處理方法1檢查GPS天線位置是否滿足120度的凈空要求。如果某段時(shí)間內(nèi)長時(shí)間反復(fù)有此告警,以及伴隨著衛(wèi)星丟失告警,甚至是反復(fù)出現(xiàn),說明GPS天線的放置位置不好,接收到的信號不理想,考慮更換地方?；蛘呔€纜鏈接松動等,此時(shí)檢查并重新連接即可。偶爾出現(xiàn)此類告警,說明同步的過程中發(fā)現(xiàn)1PPS超過了誤差,因此會告這個(gè)警,所以目前出現(xiàn)這個(gè)告警時(shí)一般不需要處理,除非這個(gè)告警總是不消失,就需要更換GPS接收機(jī)子卡。2檢查GPS信噪比是否正常。輸入―ShowTrimSVInfor1‖,就可以打開Trimble卡收到衛(wèi)星的信號質(zhì)量打印!ps:信噪比--SVQuality的單位db/hz,一般在大于40左右都是有效的,信噪比滿足要求?；蛘咧苯虞斎搿癝howUbxSVInfor1”,就可以打印Ublox卡收到衛(wèi)星的信號質(zhì)量打印!ps:信號質(zhì)量指示――SVQuality,一般是等于7有效信噪比—SVStrength的單位db/hz,一般在大于40左右都是有效的注意:因?yàn)殚_關(guān)打開,就一直是在打印這些信息,為避免影響單板正常工作,在檢查之后通過―ShowTrimSVInfor0‖或“ShowUbxSVInfor0”關(guān)閉打印。信噪比過低的可能原因有:線纜損耗過大,或者存在干擾。3檢查GPS天饋系統(tǒng)。具體可見“GPS狀態(tài)異?！辈糠?。1.4GPS其余告警碼排查一般同時(shí)會有GPS狀態(tài)異常、GPS故障,首先處理GPS狀態(tài)異常、GPS故障告警,解決后其它告警自然消除。1.5ClkShow命令介紹使用Logview登陸到BCCS(SBMP、CC單板上,用ClkShow命令多次察看,ClkShow的打印如下:下面是正常工作過程中的打印:10MPLL(WorkMode:REAL,MainSrc:0NamePriorityQualityConfigCableLengthGps011TRUE50Gps100FALSE0Mode:Keepup,DAVal:18424,Phase:0,PdDelt:4PdDeltValue0-11-1203010MClockALMStatus:Clear比較重要的信息有GPS的狀態(tài)和10MHz鎖相環(huán)當(dāng)前狀態(tài),已經(jīng)標(biāo)識為紅色。第一處紅字為GPS狀態(tài),分別是“優(yōu)先級”、“質(zhì)量”、“是否已配置”和“線纜長度”,例子中是正常情況,GPS出現(xiàn)故障時(shí)“質(zhì)量”會變?yōu)?。第二處紅字為10MHz鎖相環(huán)當(dāng)前狀態(tài),有以下這幾種:KeepUp(跟蹤,鎖相環(huán)已經(jīng)鎖定的正常工作狀態(tài)Heat(預(yù)熱,初次上電并且有可用參考源時(shí)的狀態(tài),持續(xù)10分鐘FastCapture(快捕,鎖定過程,屬于中間狀態(tài)FreeRun(自由振蕩,沒有可用參考源時(shí)的狀態(tài)下面是使用Trimble的GPS卡,在自由振蕩狀態(tài)情況下的打印:10MPLL(WorkMode:EMULATE,MainSrc:255NamePriorityQualityConfigCableLengthGps010TRUE100Gps110FALSE0Mode:Freerun,DAVal:16255,Phase:0,PdDelt:0PdDeltValue0010203
