NB-IoT則很好的解決了GPRS抄表方案所面臨的難題。NB-IoT抄表在功能上繼承了GPRS的同時，比起2G/3G/4G有了50-100倍的上行容量提升，這也就意味著，在同一基站覆蓋范圍下，NB-IoT可比現(xiàn)有無線技術(shù)提供50-100倍的接入數(shù)。這對于裝表量比較密集的小區(qū)無疑是一個更好的選擇。
基于NB-IoT的智能抄表系統(tǒng)主要由帶有NB-IoT模塊的水氣表、基站、NB-IoT核心網(wǎng)、NB-IoT管理平臺、客戶端網(wǎng)絡(luò)管理系統(tǒng)、集抄管理系統(tǒng)等構(gòu)成。水氣表將采集的水氣用量信息和自身狀態(tài)信息上傳至NB-IoT核心網(wǎng)和物聯(lián)網(wǎng)云平臺，同時也可以接收來自云平臺的控制信息?？蛻舳司W(wǎng)絡(luò)管理系統(tǒng)從NB-IoT管理云平臺獲取抄收到的居民用水/氣信息，監(jiān)控各居民的實時使用情況，水氣公司通過監(jiān)測到的數(shù)據(jù)，可對用戶的用水、氣進行實時階梯調(diào)價控制，向居民推送每月的使用量和扣費等情況。
ZG致遠電子ZM7100 NB-IoT模塊支持電信、移動頻段，支持CoAP快速與云平臺實現(xiàn)對接，目前支持的云平臺有OneNET、eCoud、Aiyun、ZWS IoT等，極大地降低了客戶跟云平臺的對接難度。且模塊支持FOTA遠程差分升級，僅需上傳數(shù)據(jù)量很小升級包的差分文件，即可完成升級。
致遠電子作為物聯(lián)網(wǎng)行業(yè)領(lǐng)軍企業(yè)，構(gòu)建工業(yè)無線互聯(lián)系統(tǒng)級解決方案專家，攜手工業(yè)互聯(lián)網(wǎng)領(lǐng)域戰(zhàn)略合作伙伴，聯(lián)合推出ZM7100 NB-IoT標準通信模塊，共同助力中國物聯(lián)網(wǎng)產(chǎn)業(yè)發(fā)展。
