Product Overview

This concentrator is a new generation centralized meter reading device developed based on ARM core. The downstream channel of the concentrator adopts RS-485 and power line carrier (or low-power wireless) communication methods to exchange data with the collector or energy meter, and complete functions such as data storage and processing; The upstream channel adopts GPRS (CDMA or fiber optic optional) and Ethernet to exchange data with the main station management system, mainly suitable for the construction of automatic meter reading systems for low-voltage residential users. The communication protocol between the concentrator and the main station should comply with the requirements of Q/GDW 11778-2017. The concentrator and local communication module should support Q/GDW 10376.2-2019, and the concentrator and remote communication module should support Q/GDW 10376.3-2019. The data communication protocol between the concentrator and the energy meter should support Q/GDW 11778-2017 and DL/T 645-1997/2007. The measurement accuracy meets the relevant requirements of Q/GDW 10827-2020.
