1.8用電信息采集系統有哪些通訊方(fang)式？
答：用電(dian)信(xin)息采(cai)集(ji)系統的(de)數據通(tong)信(xin)網(wang)絡(luo)必須(xu)穩定(ding)可(ke)靠，采(cai)集(ji)數據的(de)傳輸由遠程(cheng)通(tong)訊信(xin)和本(ben)(ben)地(di)通(tong)信(xin)兩類(lei)通(tong)信(xin)網(wang)絡(luo)構成(cheng)，分別采(cai)集(ji)終端(duan)至系統主站間的(de)遠程(cheng)數據傳輸和智(zhi)能電(dian)表至采(cai)集(ji)終端(duan)之(zhi)間的(de)本(ben)(ben)地(di)數據傳輸。
遠(yuan)程(cheng)(cheng)通信(xin)信(xin)息采(cai)集(ji)系統(tong)的數(shu)(shu)(shu)據通信(xin)網絡(luo)必(bi)須(xu)穩(wen)定可靠，采(cai)集(ji)數(shu)(shu)(shu)據的傳輸由遠(yuan)程(cheng)(cheng)通信(xin)和本地通信(xin)網絡(luo)構成，分別(bie)提供采(cai)集(ji)終端(duan)(duan)至系統(tong)主站間的遠(yuan)程(cheng)(cheng)數(shu)(shu)(shu)據傳輸和智(zhi)能電表至采(cai)集(ji)終端(duan)(duan)的本地數(shu)(shu)(shu)據傳輸。
遠程(cheng)通信可(ke)采用光(guang)纖專網、GPRS/CDMA無線(xian)(xian)公網、230MHz無線(xian)(xian)專網和中壓電力線(xian)(xian)載波(bo)等，階(jie)梯的通信方式要綜合考慮系統(tong)建設規模，技術前瞻(zhan)性(xing)，通信實時(shi)性(xing)、安全性(xing)、可(ke)靠性(xing)等因素(su)確定。
; 本地通信可采用電力線(xian)載波、微功率無線(xian)通信技(ji)術和RS-485總線(xian)相結合(he)的典型組網方式，主要有(you)兩種：
（1）“集中(zhong)器-電能表”方(fang)式(shi)是集中(zhong)器通(tong)過電力(li)線(xian)載波或微(wei)功率無線(xian)直接與智能電能表通(tong)信。
（2）“集中器-采(cai)集器-電(dian)能(neng)表(biao)”方(fang)式是集中通(tong)過電(dian)力線(xian)載波(bo)或微功率無線(xian)與(yu)采(cai)集器通(tong)信(xin)，采(cai)集器通(tong)過RS485總線(xian)與(yu)智能(neng)電(dian)能(neng)表(biao)通(tong)信(xin)。
1.9針對不同類型(xing)的電力用(yong)戶，用(yong)電信息(xi)采集系統選用(yong)哪些模式采集數據？
答(da)：大型專(zhuan)(zhuan)用(yong)(yong)(yong)變壓(ya)器用(yong)(yong)(yong)戶和(he)中(zhong)小(xiao)型專(zhuan)(zhuan)用(yong)(yong)(yong)變壓(ya)器用(yong)(yong)(yong)戶應采(cai)(cai)(cai)用(yong)(yong)(yong)“專(zhuan)(zhuan)變采(cai)(cai)(cai)集(ji)器終(zhong)端(duan)+rs-485多功能(neng)電能(neng)表”采(cai)(cai)(cai)集(ji)模式，大型專(zhuan)(zhuan)用(yong)(yong)(yong)變壓(ya)器用(yong)(yong)(yong)戶可選擇安裝(zhuang)帶(dai)交(jiao)流(liu)采(cai)(cai)(cai)樣(yang)專(zhuan)(zhuan)變終(zhong)端(duan)或(huo)不帶(dai)采(cai)(cai)(cai)樣(yang)專(zhuan)(zhuan)變終(zhong)端(duan)，中(zhong)小(xiao)型專(zhuan)(zhuan)用(yong)(yong)(yong)變壓(ya)器用(yong)(yong)(yong)戶可選擇安裝(zhuang)不帶(dai)交(jiao)流(liu)采(cai)(cai)(cai)樣(yang)終(zhong)端(duan)。
