1. 應用(yòng)場景Application Scenario

  對工廠的三(sān)相(xiāng)用電設(shè)備(bèi)的(dí)用(yòng)電量(liáng)進(jìn)行(háng)采集並上(shàng)傳(chuán)至係(xì)統， 從(cóng)而使用戶能(néng)夠實現(xiàn)在(zài)PC上就能(néng)通過(guò)IoT EMS係(xì)統查(chá)看設備用(yòng)電(diàn)情況(kuàng)。

  Customers need to collect the basic energy consumption data and upload it to management system so that they can realized real-time and remote data monitoring using their PC.

  2. 技術(shù)選型 Technical Selection

  2.1三(sān)相回(huí)路電壓為415Vac L-L，額定(dìng)電流(liú)不(bù)超(chāo)過80A AC，三(sān)相四綫(xiàn)接(jiē)綫(xiàn)，電表方麵選型三(sān)相帶RS485（MODBUS-RTU）通訊(xùn)的(dí)電表(biǎo)ADL400。

  Rated voltage of 3-phase monitoring circuits is 415Vac L-L while the rated current is below 80A AC, thus selection of metering devices will be ADL400 3-phase energy meter with RS485 communication of MODBUS-RTU protocol

  2.2工廠經(jīng)確(què)認(rèn)後WiFi覆蓋條件較好，頻(pín)段(duàn)為2.4GHz，方(fāng)便提供(gōng)220Vac供(gōng)電，網(wǎng)關選(xuǎn)用AWT100-WiFi搭配POW模(mó)塊(kuài)。支(zhī)持廣(guǎng)播自動(dòng)抄(chāo)表以便後續(xù)下(xià)行設(shè)備(bèi)的添(tiān)加。該網關(guān)上行為(wéi)4GHz WiFi，采(cǎi)用(yòng)MODBUS-RTU over TCP的(dí)透傳通訊協(xié)議。下行為(wéi)RS485通訊，采(cǎi)用MODBUS-RTU協議，從(cóng)而(ér)與ADL400配(pèi)合(hé)對(duì)數(shù)據進行上傳(chuán)至雲服務器通向係統。

  After discussing with the customer, factory is with stable 4GHz WiFi coverage and signal,and a power supply of 220Vac is preferable. So, for the gateway parts, we select AWT100-WiFi which own auto-broadcasting function that can ease the later adjustment with subsequent ADL400. Also, AWT100-WiFi is paired with AWT100-POW power module.Other than that, since AWT100-WiFi is with upstream of 2.4GHz WiFi using MODBUS-RTU over TCP protocol and downstream of RS485 using MODBUS-RTU protocol to be paired with ADL400 for energy consumption data uploaded to cloud server and finally to the IoT System.

  2.3測試階段服務器使用我司(sī)已經(jīng)租(zū)用的亞(yà)馬(mǎ)遜雲(yún)服務(wù)器(qì)以節(jié)省(shěng)客(kè)戶預算(suàn)。

  For pilot project phase, cloud server is highly recommended to use our company’s cloud server which has been rent on Amazon to save the customers’ budget on testing phase.

  2.4根據(jù)需求(qiú)係統選用(yòng)IoT EMS係統，並提供3個月試用(yòng)以(yǐ)便客戶(hù)測(cè)試。

  According to the request, IoT Energy Management System will be the most appropriate one and can provide 3-month free trial for testing use.

  3. 初(chū)期(qī)方案(àn)架構Pilot Project Solution Structure

  4. 後期方(fāng)案(àn)方向(xiàng) Plan after Pilot Project

  若初(chū)期(qī)方案測試成(chéng)功(gōng)，後期(qī)方(fāng)案方(fāng)向為：

  If pilot project proved to be successful, later plan should be as below:

  4.1雲托(tuō)管方(fāng)案：綜(zōng)合(hé)考(kǎo)慮雲服務器租用成本以及(jí)點位數(shù)量(liáng)不多(duō)的(dí)情(qíng)況，雲方案推(tuī)薦為係(xì)統軟件選(xuǎn)用(yòng)托(tuō)管，雲服務器依舊使(shǐ)用(yòng)我司(sī)的雲服(fú)務器。硬件(jiàn)設備(bèi)層無需改動，隻需後續增(zēng)訂(dìng)ADL400三(sān)相電能表(biǎo)，若點位(wèi)數(shù)量需(xū)求(qiú)較(jiào)多(duō)，根據(jù)情況(kuàng)配(pèi)套(tào)增(zēng)訂AWT100-WiFi網關。

  Cloud Hosting Service Solution: Considering about the comprehensive cost of renting the cloud server and the amount of monitoring circuits, deployment of cloud IoT Energy Management System should be paired with hosting service. In this situation, customer don’t need to afford the rent of cloud server and will use our own cloud server. Also, for the hardware of this solution, no change need be done just like in the pilot project solution structure. Customer only need to order more ADL400 3-phase energy meter and maybe paired AWT100-WiFi gateway according to the number of subsequent request.

  4.2本(běn)地買(mǎi)斷方案：若(ruò)客戶對數據(jù)保密性比較(jiào)有想法，後期推(tuī)薦方向(xiàng)為IoT係(xì)統(tǒng)買斷(duàn)服(fú)務(wù)，服務器(qì)架設本地服務(wù)器(qì)並搭(dā)配(pèi)工(gōng)業交(jiāo)換機(jī)與(yǔ)UPS電(diàn)源。硬件(jiàn)設(shè)備層(céng)電表(biǎo)依舊推薦ADL400，特殊型號ADF400L不推薦使用(yòng)，原因是(shì)在三相(xiāng)四綫(xiàn)接綫為直通式(shì)接綫而非(fēi)互感(gǎn)器(qì)接(jiē)入時，ADF400L的測量(liáng)模塊需(xū)求(qiú)數(shù)量(liáng)較(jiào)多(duō)，無(wú)法(fǎ)減(jiǎn)少成本(běn)。網關(guān)方(fāng)麵根據後期(qī)點位(wèi)數(shù)量增配(pèi)AWT100-CE或(huò)者APort100.

  Local Buy-out Service Solution: If request from customers for data safety and Confidentiality is much more higher. The buy-out service of IoT Energy Management System to be paired with a Local Server will be the best choice. Yet the solution need to do a lot of change in hardware like. First, deploying of local server need to be paired with industrial switch and UPS. Second, for energy meter, ADL400 is still more recommendable.Since the special module, ADF400L Multi-circuit energy meter with built-in Ethernet communication won’t save much budget on the application of 3-phase wiring via direct connection instead of via CTs. At last, gateway need to be changed from AWT100-WiFi to AWT100-CE or Aport100 according to the amount of subsequent request.
