电(dian)力线(xian)载(zai)(zai)波(bo)通信(xin)(xin)G3-PLC调(diao)制技术(shu)概述：1、电(dian)力线(xian)载(zai)(zai)波(bo)通信(xin)(xin)是(shi)指(zhi)利(li)用(yong)现有的(de)(de)(de)(de)(de)电(dian)力线(xian)，通过(guo)载(zai)(zai)波(bo)方式将模拟(ni)信(xin)(xin)号(hao)(hao)或数(shu)字(zi)信(xin)(xin)号(hao)(hao)进行高速(su)传递的(de)(de)(de)(de)(de)技术(shu)，在(zai)(zai)电(dian)力线(xian)载(zai)(zai)波(bo)通信(xin)(xin)系(xi)统(tong)中(zhong)(zhong)比较(jiao)基(ji)(ji)本(ben)的(de)(de)(de)(de)(de)一(yi)(yi)(yi)项(xiang)任(ren)务(wu)就是(shi)根据(ju)通信(xin)(xin)信(xin)(xin)道(dao)的(de)(de)(de)(de)(de)不(bu)同(tong)(tong)选择(ze)不(bu)同(tong)(tong)的(de)(de)(de)(de)(de)调(diao)制方式。2、一(yi)(yi)(yi)般来(lai)(lai)说，基(ji)(ji)带信(xin)(xin)号(hao)(hao)含(han)有直(zhi)(zhi)流分(fen)量和频(pin)率较(jiao)低的(de)(de)(de)(de)(de)频(pin)率分(fen)量，往(wang)往(wang)不(bu)能作为(wei)传输(shu)(shu)信(xin)(xin)号(hao)(hao)在(zai)(zai)信(xin)(xin)道(dao)中(zhong)(zhong)直(zhi)(zhi)接(jie)传输(shu)(shu)，因此，必须把基(ji)(ji)带信(xin)(xin)号(hao)(hao)转变成为(wei)一(yi)(yi)(yi)个相(xiang)对基(ji)(ji)带频(pin)率而言非常高的(de)(de)(de)(de)(de)带通信(xin)(xin)号(hao)(hao)（已调(diao)信(xin)(xin)号(hao)(hao)）以适合于(yu)信(xin)(xin)道(dao)传输(shu)(shu)。3、一(yi)(yi)(yi)个通信(xin)(xin)系(xi)统(tong)的(de)(de)(de)(de)(de)质(zhi)量再很大程(cheng)度上依(yi)赖于(yu)所采用(yong)的(de)(de)(de)(de)(de)调(diao)制方式。调(diao)制时为(wei)了使信(xin)(xin)号(hao)(hao)特(te)(te)征(zheng)与信(xin)(xin)道(dao)特(te)(te)征(zheng)相(xiang)匹配，因此，调(diao)制方式的(de)(de)(de)(de)(de)选择(ze)是(shi)由系(xi)统(tong)中(zhong)(zhong)信(xin)(xin)道(dao)特(te)(te)性来(lai)(lai)决定(ding)的(de)(de)(de)(de)(de)。显然不(bu)同(tong)(tong)类型的(de)(de)(de)(de)(de)信(xin)(xin)道(dao)特(te)(te)征(zheng)，将相(xiang)应存在(zai)(zai)着不(bu)同(tong)(tong)类型的(de)(de)(de)(de)(de)调(diao)制方式。

电(dian)力线(xian)(xian)载波(bo)通(tong)(tong)(tong)信(xin)G3-PLC可以(yi)(yi)(yi)应用于(yu)(yu)物联(lian)网：将电(dian)力线(xian)(xian)通(tong)(tong)(tong)信(xin)（PLC）应用于(yu)(yu)物联(lian)网也并(bing)非易事。众(zhong)所(suo)周知，低压电(dian)力线(xian)(xian)的(de)(de)(de)拓(tuo)扑(pu)结构和物理特性(xing)都与传(chuan)(chuan)统通(tong)(tong)(tong)信(xin)传(chuan)(chuan)输介质不同，是(shi)在已加载工频(pin)(pin)电(dian)力信(xin)号(hao)的(de)(de)(de)通(tong)(tong)(tong)路上传(chuan)(chuan)输高速数据信(xin)息(xi)，因此带来了(le)工作环境恶(e)劣(lie)、噪(zao)声干扰严重以(yi)(yi)(yi)及时变性(xing)大等问题；同时，信(xin)号(hao)很容(rong)易产生反(fan)射(she)、驻(zhu)波(bo)和谐振等现(xian)象(xiang)，令(ling)信(xin)号(hao)的(de)(de)(de)衰(shuai)减特性(xing)极(ji)其(qi)复(fu)杂，造成(cheng)PLC信(xin)道具(ju)有很强的(de)(de)(de)频(pin)(pin)率选(xuan)(xuan)择性(xing)。而电(dian)力线(xian)(xian)载波(bo)通(tong)(tong)(tong)信(xin)G3-PLC可以(yi)(yi)(yi)根据频(pin)(pin)率选(xuan)(xuan)择特性(xing)确定较佳信(xin)号(hao)传(chuan)(chuan)输频(pin)(pin)率，并(bing)通(tong)(tong)(tong)过大量的(de)(de)(de)实测数据分析获得电(dian)力线(xian)(xian)的(de)(de)(de)信(xin)道特性(xing)，针对这(zhei)些特征(zheng)设计有效的(de)(de)(de)抗噪(zao)声技术和防衰(shuai)减技术，大幅地提高了(le)电(dian)力线(xian)(xian)的(de)(de)(de)通(tong)(tong)(tong)信(xin)性(xing)能，实现(xian)高速、可靠、实时的(de)(de)(de)长距(ju)离通(tong)(tong)(tong)信(xin)。电(dian)力线(xian)(xian)载波(bo)通(tong)(tong)(tong)信(xin)G3-PLC，是(shi)一种通(tong)(tong)(tong)过电(dian)线(xian)(xian)进行数据传(chuan)(chuan)输的(de)(de)(de)通(tong)(tong)(tong)信(xin)技术。

电(dian)力(li)线(xian)载(zai)波(bo)(bo)(bo)(bo)通(tong)(tong)(tong)信(xin)(xin)(xin)(xin)G3-PLC的(de)(de)(de)原理：1、电(dian)力(li)线(xian)载(zai)波(bo)(bo)(bo)(bo)通(tong)(tong)(tong)信(xin)(xin)(xin)(xin)是指利(li)用现(xian)有(you)的(de)(de)(de)电(dian)力(li)线(xian)，通(tong)(tong)(tong)过载(zai)波(bo)(bo)(bo)(bo)方式(shi)(shi)将模拟(ni)信(xin)(xin)(xin)(xin)号(hao)(hao)或数字信(xin)(xin)(xin)(xin)号(hao)(hao)进(jin)行高速传(chuan)(chuan)递的(de)(de)(de)技术，在(zai)电(dian)力(li)线(xian)载(zai)波(bo)(bo)(bo)(bo)通(tong)(tong)(tong)信(xin)(xin)(xin)(xin)系(xi)统中(zhong)比较(jiao)基(ji)(ji)本(ben)的(de)(de)(de)一(yi)(yi)(yi)项任务就是根(gen)据通(tong)(tong)(tong)信(xin)(xin)(xin)(xin)信(xin)(xin)(xin)(xin)道(dao)(dao)的(de)(de)(de)不(bu)同(tong)选(xuan)择不(bu)同(tong)的(de)(de)(de)调制(zhi)(zhi)方式(shi)(shi)。2、一(yi)(yi)(yi)般来说，基(ji)(ji)带信(xin)(xin)(xin)(xin)号(hao)(hao)含有(you)直(zhi)流分(fen)(fen)量和频(pin)率(lv)较(jiao)低的(de)(de)(de)频(pin)率(lv)分(fen)(fen)量，往往不(bu)能作为传(chuan)(chuan)输信(xin)(xin)(xin)(xin)号(hao)(hao)在(zai)信(xin)(xin)(xin)(xin)道(dao)(dao)中(zhong)直(zhi)接传(chuan)(chuan)输，因此，必须(xu)把基(ji)(ji)带信(xin)(xin)(xin)(xin)号(hao)(hao)转变(bian)成为一(yi)(yi)(yi)个(ge)相(xiang)对基(ji)(ji)带频(pin)率(lv)而言非常高的(de)(de)(de)带通(tong)(tong)(tong)信(xin)(xin)(xin)(xin)号(hao)(hao)(已调信(xin)(xin)(xin)(xin)号(hao)(hao))以适合于(yu)信(xin)(xin)(xin)(xin)道(dao)(dao)传(chuan)(chuan)输。3、一(yi)(yi)(yi)个(ge)通(tong)(tong)(tong)信(xin)(xin)(xin)(xin)系(xi)统的(de)(de)(de)质量再很大程度上依赖于(yu)所采用的(de)(de)(de)调制(zhi)(zhi)方式(shi)(shi)。调制(zhi)(zhi)时(shi)为了使信(xin)(xin)(xin)(xin)号(hao)(hao)特(te)(te)征(zheng)与信(xin)(xin)(xin)(xin)道(dao)(dao)特(te)(te)征(zheng)相(xiang)匹配，因此，调制(zhi)(zhi)方式(shi)(shi)的(de)(de)(de)选(xuan)择是由系(xi)统中(zhong)信(xin)(xin)(xin)(xin)道(dao)(dao)特(te)(te)性来决定的(de)(de)(de)。显(xian)然(ran)不(bu)同(tong)类型的(de)(de)(de)信(xin)(xin)(xin)(xin)道(dao)(dao)特(te)(te)征(zheng)，将相(xiang)应存(cun)在(zai)着(zhe)不(bu)同(tong)类型的(de)(de)(de)调制(zhi)(zhi)方式(shi)(shi)。电(dian)力(li)线(xian)载(zai)波(bo)(bo)(bo)(bo)通(tong)(tong)(tong)信(xin)(xin)(xin)(xin)G3-PLC可以应用于(yu)智慧城(cheng)市(shi)、智慧家居(ju)和工业控制(zhi)(zhi)领域(yu)。智能电(dian)表G3-PLC电(dian)力(li)线(xian)通(tong)(tong)(tong)信(xin)(xin)(xin)(xin)应用领域(yu)
