一、什么是集中器

集中器是连接终端、计算机或通信设备的中心连接点设备。它成为电缆汇合的中心点。在若干终端密集区内，通常为减少通信线路，先把终端接到集中器，然后再经过高速线路将集中器连接到计算机的通信控制器，因此，集中器也是共享线路和提高线路利用率的一种有效设备。

二、什么是采集器

数据采集器具备实时采集、自动存储、即时显示、即时反馈、自动处理、自动传输功能。为现场数据的真实性、有效性、实时性、可用性提供了保证。其具有一体性、机动性、体积小、重量轻、高性能，并适于手持等特点。

采集器的位置处于电表和集中器之间，即电表–采集器–集中器。

三、采集器和集中器的功能

采集器主要有三个功能：采集电表数据（如峰、谷、平不同时段的数据）、保存、通过电力载波响应集中器的命令上传数据或向电表下传执行命令（如电表有可以切断用户用电的功能）。

采集器还可通过红外通讯接口，在现场与手抄器通信，接受手抄器发出的各种命令，传送采集器所记录的各种数据。

通过采集电表脉冲或rs232等通讯方式管理12块、32块或64块电表（可以根据电表的数量选择不同型号的采集器），然后通过电力载波把这些电表的数据上传给集中器。

集中器通常一个变台区一个，装在变压器附近，如配电室。

What is a concentrator

A concentrator is a central point of connection device that connects a terminal, computer or communication device. It becomes the central point where the cables converge. In a number of terminal dense areas, usually in order to reduce the communication line, the terminal is first connected to the concentrator, and then through the high-speed line to connect the concentrator to the communication controller of the computer, so the concentrator is also an effective device to share the line and improve the utilization of the line.

Two, what is the collector

The data collector has the functions of real-time collection, automatic storage, instant display, instant feedback, automatic processing, and automatic transmission. It provides guarantee for the authenticity, validity, real-time and availability of field data. It has the characteristics of unity, mobility, small size, light weight, high performance, and suitable for hand-held.

The collector is located between the meter and the concentrator, that is, the meter – collector – concentrator.

Three, collector and concentrator functions

The collector has three main functions: collecting meter data (such as peak, valley, and flat data at different times), saving, uploading data through the command of the power carrier response concentrator or transmitting commands to the meter (such as the meter can cut off the user’s power use function).

The collector can also communicate with the hand-copy device on the spot through the infrared communication interface, accept various commands issued by the hand-copy device, and transmit various data recorded by the collector.

Manage 12, 32 or 64 meters by means of communication such as collecting meter pulses or rs232 (different types of collectors can be selected according to the number of meters), and then transmit the data of these meters to the concentrator through the power carrier.

The concentrator is usually one in each transformer area, installed near the transformer, such as the distribution room.
