国网智能集中器 State Grid Intelligent Concentrator 1、概述1. Introduction DJGZ23-SDLN16GW 型国网集中器（简称集中器）是低压电力集中抄表系统中的关键设备。集中器能够通过下行信道自动抄收并存储各种具有载波通信或RS485串行通讯的智能仪表、国网集中器或采集模块以及各类载波通信终端的电量数据；同时能通过上行信道与主站或手持设备进行数据交换，上行信道采用公用通讯网，支持客户端、服务器两种通讯模式，并且采用模块化设计，可通过更换通信模块直接改变通信方式。符合IEC国际电工委员会相关标准，符合用电信息采集系统主站与国网集中器通信协议，符合国网集中器技术条件和型式规范。 DJGZ23-SDLN16GW State Grid Concentrator (Concentrator for short) is the key device of low voltage electricity centralized meter reading system. The concentrator can read and save the end electric data of intelligent meter, state grid concentrator with carrier communication or RS485 serial communications, collection module or carrier communication terminal through downlink channel; meanwhile, it can exchange data with master station or handheld device through upstream channel with use public communication network to support two communication mode of client and server with modular design to change communication mode through changing module. The concentrator is corresponding with the standard of IEC, with the communication protocol between power collection system and state grid concentrator and with the technique and specification of state grid concentrator. 2、功能介绍 2. Function informationl 数据采集、处理 I. Data collection and process系统采集的主要数据项有： Major items for collection include: 电能量数据：总电能示值、各费率电能示值、总电能量、各费率电能量、最大需量等；Electric energy data: total indicated energy value, all rate indicated energy value, total electric energy and maximum demand; 交流模拟量：电压、电流、有功功率、无功功率、功率因数等； AC analog data: voltage, current, active power, reactive power, power factor; 直流模拟量采集：对一些非电气量监测点（如：温度、压力等），经变换器转换成直流模拟量；集中器可实时采集直流模拟量测量温度、压力等非电气量，直流模拟量测量准确度在±1％范围内。DC analog data: change non-electric parameter monitoring point (like temperature and voltage) into DC analog data through convertor; the concentrator can collect DC analog data to measure non-electric data of temperature and voltage with accuracy within ±1%.状态量采集：终端实时采集开关位置状态和其它状态信息，发生变位时应记入内存并在最近一次主站查询时向其发送该变位信号或终端主动上报。 Q
