智能電表(biao)在設計上有些什么突破智能電(dian)(dian)網用電(dian)(dian)信(xin)息采集(ji)(ji)系統中，智能電(dian)(dian)表介(jie)于電(dian)(dian)力(li)(li)用戶(hu)和(he)信(xin)息采集(ji)(ji)現場終(zhong)端(duan)之間(jian)，主要完成電(dian)(dian)力(li)(li)用戶(hu)用電(dian)(dian)信(xin)息的(de)(de)提供、管理和(he)傳遞(di)，是智能電(dian)(dian)網的(de)(de)底層終(zhong)端(duan)設備。

1、信息的提供：計量技術的突破

從功能上講(jiang)，傳(chuan)統電(dian)(dian)(dian)表(biao)只要求(qiu)計量有功電(dian)(dian)(dian)能，智(zhi)能電(dian)(dian)(dian)表(biao)能夠(gou)實現(xian)更(geng)多的計量和測(ce)量功能，比如電(dian)(dian)(dian)網電(dian)(dian)(dian)壓、電(dian)(dian)(dian)流、功率(lv)、頻率(lv)等參(can)數。電(dian)(dian)(dian)表(biao)的核心任務(wu)是(shi)(shi)電(dian)(dian)(dian)能計量，但是(shi)(shi)電(dian)(dian)(dian)能計量已不再是(shi)(shi)智(zhi)能電(dian)(dian)(dian)表(biao)的功能，智(zhi)能電(dian)(dian)(dian)表(biao)需要提供更(geng)多的電(dian)(dian)(dian)力使用狀況參(can)數，并將這些信息進行(xing)收集、分析和交互管理后(hou)產生有用的信息，電(dian)(dian)(dian)力系統再以此實時地(di)做出更(geng)好的用電(dian)(dian)(dian)決策和電(dian)(dian)(dian)力系統配(pei)置(zhi)優化。

從性能上(shang)講(jiang)，傳統電(dian)表精(jing)度(du)(du)等(deng)級較低，隨著計(ji)量技術的(de)(de)(de)(de)發(fa)展，智(zhi)(zhi)能電(dian)表在計(ji)量的(de)(de)(de)(de)精(jing)度(du)(du)、動(dong)態范圍等(deng)指標(biao)上(shang)都(dou)有了很大(da)的(de)(de)(de)(de)提高，在啟(qi)動(dong)潛動(dong)上(shang)也可以做的(de)(de)(de)(de)更準(zhun)確(que)，可以實(shi)現(xian)軟件校表大(da)提高生(sheng)產效率。實(shi)際(ji)上(shang)，目前(qian)的(de)(de)(de)(de)智(zhi)(zhi)能電(dian)表尤其是智(zhi)(zhi)能單相表提供的(de)(de)(de)(de)精(jing)度(du)(du)等(deng)級已遠(yuan)(yuan)遠(yuan)(yuan)超過標(biao)準(zhun)要求。

從(cong)可(ke)(ke)(ke)靠(kao)性(xing)上講(jiang)，傳統(tong)電(dian)(dian)(dian)(dian)表(biao)尤其是感應(ying)(ying)式電(dian)(dian)(dian)(dian)表(biao)，其抗干擾(rao)性(xing)能(neng)(neng)(neng)(neng)(neng)(neng)、防(fang)竊電(dian)(dian)(dian)(dian)性(xing)能(neng)(neng)(neng)(neng)(neng)(neng)、溫度性(xing)能(neng)(neng)(neng)(neng)(neng)(neng)等方(fang)面(mian)都比較差，一(yi)些不法(fa)(fa)用(yong)(yong)(yong)戶(hu)很容(rong)易通(tong)過(guo)簡單的(de)(de)(de)(de)(de)手段干擾(rao)電(dian)(dian)(dian)(dian)表(biao)的(de)(de)(de)(de)(de)正常(chang)運行，進而達到竊電(dian)(dian)(dian)(dian)的(de)(de)(de)(de)(de)目的(de)(de)(de)(de)(de)。智能(neng)(neng)(neng)(neng)(neng)(neng)電(dian)(dian)(dian)(dian)能(neng)(neng)(neng)(neng)(neng)(neng)表(biao)借(jie)助遠程通(tong)信功(gong)能(neng)(neng)(neng)(neng)(neng)(neng)，用(yong)(yong)(yong)戶(hu)在(zai)異地可(ke)(ke)(ke)以(yi)通(tong)過(guo)互(hu)聯(lian)網(wang)或者移(yi)動通(tong)信網(wang)絡對家(jia)里的(de)(de)(de)(de)(de)各種智能(neng)(neng)(neng)(neng)(neng)(neng)負(fu)荷，如(ru)空調、洗衣機(ji)、冰箱(xiang)、照明等實現(xian)遠端(duan)開關控制(zhi)，同時通(tong)過(guo)智能(neng)(neng)(neng)(neng)(neng)(neng)電(dian)(dian)(dian)(dian)表(biao)的(de)(de)(de)(de)(de)遠端(duan)通(tong)信功(gong)能(neng)(neng)(neng)(neng)(neng)(neng)還可(ke)(ke)(ke)以(yi)實現(xian)異地監控和報警。智能(neng)(neng)(neng)(neng)(neng)(neng)電(dian)(dian)(dian)(dian)能(neng)(neng)(neng)(neng)(neng)(neng)表(biao)作為電(dian)(dian)(dian)(dian)網(wang)的(de)(de)(de)(de)(de)入戶(hu)接口(kou)，一(yi)方(fang)面(mian)電(dian)(dian)(dian)(dian)網(wang)通(tong)過(guo)智能(neng)(neng)(neng)(neng)(neng)(neng)電(dian)(dian)(dian)(dian)表(biao)將安全、高質的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)能(neng)(neng)(neng)(neng)(neng)(neng)輸(shu)送(song)到用(yong)(yong)(yong)戶(hu)的(de)(de)(de)(de)(de)用(yong)(yong)(yong)電(dian)(dian)(dian)(dian)設備(bei)上;而隨著新(xin)能(neng)(neng)(neng)(neng)(neng)(neng)源(yuan)的(de)(de)(de)(de)(de)廣(guang)泛應(ying)(ying)用(yong)(yong)(yong)，許多分布式新(xin)能(neng)(neng)(neng)(neng)(neng)(neng)源(yuan)，如(ru)風能(neng)(neng)(neng)(neng)(neng)(neng)、太陽能(neng)(neng)(neng)(neng)(neng)(neng)等，已經(jing)在(zai)用(yong)(yong)(yong)戶(hu)端(duan)得(de)到了(le)充分的(de)(de)(de)(de)(de)使用(yong)(yong)(yong)，這種微型分布式能(neng)(neng)(neng)(neng)(neng)(neng)源(yuan)也可(ke)(ke)(ke)以(yi)通(tong)過(guo)智能(neng)(neng)(neng)(neng)(neng)(neng)電(dian)(dian)(dian)(dian)表(biao)反(fan)饋到電(dian)(dian)(dian)(dian)網(wang)中，與電(dian)(dian)(dian)(dian)網(wang)實現(xian)并網(wang)。所以(yi)智能(neng)(neng)(neng)(neng)(neng)(neng)電(dian)(dian)(dian)(dian)表(biao)需要具備(bei)雙(shuang)向電(dian)(dian)(dian)(dian)能(neng)(neng)(neng)(neng)(neng)(neng)傳輸(shu)和計量的(de)(de)(de)(de)(de)功(gong)能(neng)(neng)(neng)(neng)(neng)(neng)。智能(neng)(neng)(neng)(neng)(neng)(neng)電(dian)(dian)(dian)(dian)表(biao)采用(yong)(yong)(yong)領(ling)先的(de)(de)(de)(de)(de)現(xian)代集成電(dian)(dian)(dian)(dian)路設計技術，可(ke)(ke)(ke)以(yi)保證(zheng)在(zai)強干擾(rao)、寬(kuan)溫度范圍下(xia)的(de)(de)(de)(de)(de)精(jing)確可(ke)(ke)(ke)靠(kao)計量，有效的(de)(de)(de)(de)(de)保障電(dian)(dian)(dian)(dian)網(wang)公(gong)(gong)司和合(he)法(fa)(fa)用(yong)(yong)(yong)戶(hu)的(de)(de)(de)(de)(de)權益，實現(xian)用(yong)(yong)(yong)電(dian)(dian)(dian)(dian)的(de)(de)(de)(de)(de)公(gong)(gong)平和公(gong)(gong)正。

2、信息(xi)的管理：智能管理的突破

傳(chuan)統電(dian)表沒有MCU或者MCU只(zhi)承擔很簡單的管理功能(neng)，其信息(xi)通過字輪(lun)來顯(xian)示，僅能(neng)提(ti)供電(dian)量數據(ju)給用戶，不能(neng)對用電(dian)采(cai)集進行(xing)智能(neng)管理。

智(zhi)能電(dian)(dian)表的(de)(de)MCU系統(tong)擔負用(yong)電(dian)(dian)信(xin)息(xi)的(de)(de)存儲、用(yong)電(dian)(dian)信(xin)息(xi)的(de)(de)顯示和用(yong)電(dian)(dian)信(xin)息(xi)的(de)(de)傳(chuan)(chuan)遞等(deng)管(guan)理功能。通過對存儲模塊、時鐘模塊、加(jia)密模塊、計(ji)量模塊、通信(xin)模塊、預(yu)付費(fei)卡等(deng)的(de)(de)有效管(guan)理，智(zhi)能電(dian)(dian)表可(ke)以實現(xian)預(yu)付費(fei)、復費(fei)率(lv)、階(jie)梯電(dian)(dian)價(jia)等(deng)用(yong)電(dian)(dian)方(fang)式的(de)(de)管(guan)理，實現(xian)自(zi)動拉合閘、自(zi)動報警等(deng)安全措施的(de)(de)管(guan)理，實現(xian)自(zi)動控制、自(zi)動抄表等(deng)信(xin)息(xi)傳(chuan)(chuan)遞的(de)(de)管(guan)理。

使用(yong)智(zhi)能電表，電力(li)用(yong)戶可根(gen)據用(yong)電信息改(gai)變用(yong)電習慣、選擇用(yong)電方式和(he)時間，提高能源(yuan)使用(yong)效率，減少能源(yuan)的(de)浪費，實(shi)現(xian)電能的(de)合(he)理利用(yong)。

使(shi)用(yong)(yong)智能(neng)電(dian)表，電(dian)網公司可(ke)利用(yong)(yong)智能(neng)電(dian)表對用(yong)(yong)電(dian)信息進行監測，及時發(fa)現存在的(de)(de)問題(ti)甚至電(dian)力(li)故障，為用(yong)(yong)戶(hu)提供用(yong)(yong)電(dian)咨詢；每戶(hu)的(de)(de)電(dian)力(li)需(xu)求可(ke)以詳細把握，并根據(ju)需(xu)求調節發(fa)電(dian)與(yu)配電(dian)設備，平衡高峰(feng)和低谷需(xu)求期(qi)的(de)(de)用(yong)(yong)電(dian)量，形成發(fa)電(dian)、配電(dian)與(yu)用(yong)(yong)電(dian)的(de)(de)及時互(hu)動，減少大面(mian)積停電(dian)、斷電(dian)等影響(xiang)社會正常生產、生活(huo)的(de)(de)事件(jian)發(fa)生。

3、信(xin)息(xi)的傳遞：通信(xin)技術的突破

傳統電(dian)表(biao)是電(dian)網(wang)中一個(ge)(ge)個(ge)(ge)孤立的(de)終(zhong)端，用電(dian)信息依靠人(ren)工抄(chao)表(biao)來(lai)收集，效(xiao)率和可靠性(xing)都不能(neng)得(de)到保障。而(er)智(zhi)能(neng)電(dian)網(wang)依靠各種通信手(shou)段將智(zhi)能(neng)電(dian)表(biao)納入統一的(de)網(wang)絡中，智(zhi)能(neng)電(dian)表(biao)作為(wei)智(zhi)能(neng)電(dian)網(wang)的(de)智(zhi)能(neng)終(zhong)端節點，可以實現自(zi)動(dong)抄(chao)表(biao)、自(zi)動(dong)控制等(deng)功能(neng)，大大提高了效(xiao)率和可靠性(xing)。

智能電(dian)網常用的通(tong)信方式(shi)包括電(dian)力線載波(bo)、485、GPRS、小無線、光(guang)纖等(deng)(deng)，這些通(tong)信方式(shi)各有優缺點(dian)，通(tong)信模式(shi)將根據終應用進(jin)行選擇(ze)，如智能電(dian)表與(yu)采(cai)集(ji)器(qi)(qi)/集(ji)中(zhong)器(qi)(qi)之(zhi)間一般采(cai)用載波(bo)和485等(deng)(deng)方式(shi)，采(cai)集(ji)器(qi)(qi)/集(ji)中(zhong)器(qi)(qi)與(yu)主站之(zhi)間一般采(cai)用GPRS、光(guang)纖等(deng)(deng)方式(shi)。
