　　Abstract:This article describes the application of prepaid public energy meter in South Africa. Single-phase prepaid  public meters and three-phase prepaid public meters are new prepaid electric energy meters that integrate measurement and control. They support radio frequency recharge and remote recharge, and have multiple control modes such as payment control, time control, and vicious load control. It can be built-in 100A large-capacity magnetic latching relay to realize partial closing of the electric meter, and it can also provide passive dry contact output to control the external circuit breaker to realize the tripping function. It is widely used in the management of prepaid electricity consumption in commercial plazas, residential dormitories and college dormitories.

，三相(xiāng)的灌(guàn)溉表(biǎo)及(jí)本地(dì)預(yù)付(fù)費(fèi)充值(zhí)係(xì)統。

　　This company is a charging pile company in South Africa. The company wants to purchase single-phase and three-phase prepaid meters for testing. Through the time control and payment control functions of prepaid meters, it can realize the purpose of multiple people using charging piles for charging. After understanding the customer's application scenarios and needs, single-phase and three-phase public meters and local prepaid recharge systems were recommended.

　　2. 預付費灌(guàn)溉表(biǎo)的(dí)優點

　　Advantages of prepaid public energy meter

　　預付(fù)費電(diàn)表(biǎo)先付(fù)費後用電與(yǔ)傳(chuán)統後(hòu)付費電(diàn)表相比(bǐ)，導(dǎo)軌(guǐ)式預(yù)付費灌溉表(biǎo)具(jù)有(yǒu)以下優點：

　　1）導軌式(shì)安(ān)裝，無需在牆麵(miàn)上打孔(kǒng)，破壞(huài)建築，隻需要將(jiāng)表卡(qiǎ)在(zài)35mm導軌上即(jí)可，安裝方便(biàn)快(kuài)捷(jié)且(qiě)不會對安裝地造(zào)成(chéng)損(sǔn)壞；

　　2）區別(bié)於(yú)傳(chuán)統(tǒng)先計量再收費模式，實(shí)行(háng)先付費(fèi)後用電(diàn)的模式(shì)，方便對用戶的統一(yī)管理(lǐ)，節省了抄表及收費(fèi)的(dí)時(shí)間(jiān)和人(rén)工成本，解(jiě)決了(liǎo)收(shōu)費困(kùn)難的(dí)問題(tí)；

　　3）以(yǐ)卡為(wéi)介(jiè)質(zhì)，將電(diàn)費(fèi)通過刷卡形(xíng)式充入電能(néng)表內。內控(kòng)型電表(biǎo)，支持遠程充值(zhí)，減少(shǎo)人力維護成本(běn)，提高用(yòng)戶(hù)體(tǐ)驗。

　　Compared with traditional post-paid energy meters, the guide rail type prepaid public meters have the following advantages:

　　1) Rail-type installation, no need to punch holes on the wall and damage the building, just clip the watch on the 35mm rail, which is convenient and quick to install and will not cause damage to the installation site;

　　2) Different from the traditional metering and then charging mode, it implements the mode of paying first and then using electricity, which facilitates the unified management of users, saves the time and labor cost of meter reading and charging, and solves the problem of charging difficulties;

　　3) Using the card as the medium, charge the electricity bill into the electric energy meter by swiping the card. The internally controlled electric meter supports remote recharge, reduces manpower maintenance costs, and improves user experience.

　　4.應用(yòng)Application

　　此灌溉(gài)表原(yuán)本是(shì)應(yīng)用於(yú)本(běn)土的農(nóng)業(yè)灌(guàn)溉，因客(kè)戶(hù)的應(yīng)用場(cháng)景(jǐng)及公共使用的需(xū)求(qiú)，經(jīng)項目評(píng)估可(kě)以(yǐ)用於(yú)電(diàn)動車充電樁(zhuāng)的(dí)公共場(cháng)所刷卡充值。我們為使(shǐ)用者(zhě)配備一張RF 卡，通過讀(dú)卡(qiǎ)器及(jí)預付費充值(zhí)係統(tǒng)，可(kě)以為使用(yòng)者(zhě)購電寫卡(qiǎ)以(yǐ)及(jí)回收(shōu)清零(líng)，用(yòng)戶(hù)有(yǒu)充電需求時，隻(zhī)需(xū)在電(diàn)表(biǎo)上(shàng)刷(shuā)一下(xià)即可開始(shǐ)充電，充滿後(hòu)再刷(shuā)一下(xià)則(zé)取(qǔ)回卡(qiǎ)中餘款(kuǎn)，使用(yòng)方便(biàn)快(kuài)捷。

　　This public energy meter was originally used for local agricultural irrigation. Due to the customer's application scenarios and public use needs, it can be used for recharging in public places of electric vehicle charging piles after project evaluation. We provide users with an RF card. Through the card reader and prepaid recharge system, users can purchase electricity, write cards, and reset them. When users need to charge, they only need to swipe the meter to start charging. , Swipe again after full charge to retrieve the balance in the card, which is convenient and quick to use.

　　5.結(jié)論Conclusion

　　隨著環(huán)境問(wèn)題(tí)的(dí)突(tū)出(chū)，電(diàn)動汽(qì)車已經越(yuè)來越成(chéng)為未來(lái)交通(tōng)工(gōng)具的主流(liú)，與之配備的(dí)充電(diàn)樁的需求(qiú)也(yě)越(yuè)來越(yuè)大，公(gōng)共(gòng)電動(dòng)汽(qì)車充(chōng)電樁(zhuāng)通(tōng)過預付(fù)費表控製(zhì)啟(qǐ)停在未(wèi)來(lái)將為更(gēng)多(duō)的使(shǐ)用(yòng)者(zhě)提供(gōng)方便快(kuài)捷的(dí)服務。未(wèi)來安(ān)科瑞將提(tí)供(gōng)更加(jiā)智能化的(dí)預付(fù)費平台，更方(fāng)便於(yú)用(yòng)戶的使用和統(tǒng)一(yī)的管理(lǐ)。

　　With the emergence of environmental problems, electric vehicles have become the mainstream of future transportation, and the demand for charging piles equipped with them is also increasing. Public electric vehicle charging piles will be controlled by the prepaid meter to start and stop in the future. More users provide convenient and efficient services. In the future, Acrel will provide a more intelligent prepaid platform, which is more convenient for users to use and unified management.
