因此GPRS遠(yuǎn)程抄表便應(yīng)運(yùn)而生,它解決了人工抄表一系列問(wèn)題,效率更高,更,用戶(hù)繳費(fèi)更加便捷。但是,GPRS表也產(chǎn)生了一些問(wèn)題,通訊基站用戶(hù)容量比較小,功耗高,信號(hào)差。而普遍的水氣表都要求是電池供電,因此這對(duì)表類(lèi)的功耗提出了很高的要求,一般2G通信的瞬時(shí)電流可達(dá)到2A,這對(duì)電池性能的選型和成本控制增加了很大困難
ZG致遠(yuǎn)電子ZM7100 NB-IoT模塊支持電信、移動(dòng)頻段,支持CoAP快速與云平臺(tái)實(shí)現(xiàn)對(duì)接,目前支持的云平臺(tái)有OneNET、eCoud、Aiyun、ZWS IoT等,極大地降低了客戶(hù)跟云平臺(tái)的對(duì)接難度。且模塊支持FOTA遠(yuǎn)程差分升級(jí),僅需上傳數(shù)據(jù)量很小升級(jí)包的差分文件,即可完成升級(jí)。
致遠(yuǎn)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(wú)線互聯(lián)系統(tǒng)級(jí)解決方案專(zhuān)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(biāo)準(zhǔn)通信模塊,共同助力中國(guó)物聯(lián)網(wǎng)產(chǎn)業(yè)發(fā)展。
美蓓亞三美在車(chē)用旋轉(zhuǎn)變壓器傳感器領(lǐng)域擁有良好的市場(chǎng)業(yè)績(jī),并首次開(kāi)發(fā)了面向步進(jìn)電機(jī)的新型旋轉(zhuǎn)變壓器,用于機(jī)器人、辦公自動(dòng)化設(shè)備和醫(yī)療/護(hù)理設(shè)備等消費(fèi)及工業(yè)設(shè)備應(yīng)用。作為全球32位微控制器(MCU)市場(chǎng)的(注2),瑞薩開(kāi)發(fā)了一款支持美蓓亞三美新型步進(jìn)電機(jī)的全新旋變數(shù)字轉(zhuǎn)換器(RDC),以及可通過(guò)32位RX MCU實(shí)現(xiàn)RDC控制的驅(qū)動(dòng)軟件。瑞薩還帶來(lái)基于旋轉(zhuǎn)變壓器的步進(jìn)電機(jī)控制套件,其中提供開(kāi)發(fā)工具,包括美蓓亞三美帶有旋轉(zhuǎn)變壓器的步進(jìn)電動(dòng)機(jī)和帶有RDC的評(píng)估板,從而使用戶(hù)能夠快速啟動(dòng)應(yīng)用程序開(kāi)發(fā)。
