1.項目概述  Project Overview

中國香港某項目需要一批物聯網電力儀表且具備遠程抄表功能更換原先的指針表，經推薦我司APM810多功能儀表和AWT100/4GH網關以及物聯網平臺。中國香港客戶多方面對比后，認可我們的儀表安裝方便，功能強大，且結合我們的網關(AWT系列)，具備遠程抄表功能，客戶通過手機APP或網頁登錄即可隨時隨地監控用電情況。

A project in Hong Kong requires a batch of Internet of Things power meters with remotely reading function to replace the original pointer meter. We have recommended our APM810 multi-function power meter, AWT100/4GHW gateway and IoT Cloud Platform.After comparing in various aspects, Hong Kong customer recognize that our power meter is convenient to install with rich functions.Using with our gateway(AWT series), it could connect with our IoT Cloud Platform and check the data remotely. Customers can monitor the electricity situation anytime and anywhere through phone APP or web login.

2.產品介紹 Product Presentation

   APM系列網絡電力儀表具有全電參量測量，例如三相電流，電壓，有源電源，無功功率，表觀功率，頻率，功率因數。它還有電能統計，事件記錄，諧波測量及網絡通訊等功能。

APM series meters integrate measurement of full electric parameters, such as three-phase current, voltage, active power, reactive power, apparent power, frequency, power factor. It also has functions of energy statistics, event record,harmonic measurement.

AWT100數據轉換模塊是由acrel電氣公司推出的一個新的數據轉換DTU。通信數據轉換包括2G、4G、NB、LoRa、LoRaWAN、GPS、WiFi、CE、DP等通信方法。下行接口提供了一個標準的RS485數據接口。方便連接電表、rtu、plc、工業計算機等設備，一次只需完成初始配置即可完成MODBUS設備的數據采集；同時，AWT100系列無線通信終端使用強大的微處理芯片配合內置看門技術，性能可靠穩定。

AWT100 data conversion module is a new data conversion DTU launched by Acrel Electric. Communication data conversion includes 2G, 4G, NB, LoRa, LoRaWAN, GPS, WiFi, CE, DP and other communication methods. The downlink interface provides a standard RS485 data interface. It can be easily connected to power meters, RTUs, PLCs, industrial computers and other equipment, and only needs to complete the initial configuration at a time to complete the data collection of the MODBUS equipment; at the same time, the AWT100 series of wireless communication terminals use powerful micro-processing chips to cooperate Built-in watchdog technology, reliable and stable performance.
