什么是集中器
集中器是連接終端、計算機或通信設備的中心連接點設備。它成為電纜匯合的中心點。在若干終端密集區(qū)內,通常為減少通信線路,先把終端接到集
中器,然后再經過高速線路將集中器連接到計算機的通信控制器,因此,集中器也是共享線路和提高線路利用率的一種有效設備。
二、什么是采集器.
數據采集器具備實時采集、自動存儲、 即時顯示、即時反饋、自動處理、 自動傳輸功能。為現(xiàn)場數據的真實性、有效性、實時性、可用性提供了保
證。具有一體性、機動性、體積小、量輕、高性能,并適于手持等特點。
采集器的位置處于電表和集中器之間,即電表-采集器集中器。
三、采集器和集中器的功能
采集器主要有三個功能:采集電表數據(如峰、谷、平不同時段的數據)、保存、 通過電力載波響應集中器的命令上傳數據或向電表下傳執(zhí)行命令
(如電表有可以切斷用戶用電的功能)。
采集器還可通過紅外通訊接口,在現(xiàn)場與手抄器通信,接受手 抄器發(fā)出的各種命令,傳送采集器所記錄的各種數據。
通過采集電表脈沖或rs232等通訊方式管理12塊、32塊或64塊電表(可以根據電表的數量選擇不同型號的采集器),然后通過電力載波把這些電表
的數據_上傳給集中器。
集中器通常一個變臺區(qū)- -個,裝在變壓器附近,如配電室。
What is a concentrator
A concentrator is a central connection point device that connects terminals, computers, or communication devices. It becomes the central point of cable convergence. In several terminal dense areas, usually to reduce communication lines, the terminals are first connected to the centralized network
The concentrator is then connected to the computer's communication controller through high-speed lines, making it an effective device for sharing lines and improving line utilization.
2、 What is a collector
The data collector has functions of real-time collection, automatic storage, real-time display, real-time feedback, automatic processing, and automatic transmission. Provided guarantees for the authenticity, effectiveness, real-time performance, and availability of on-site data
Certificate. It has the characteristics of integration, mobility, small size, light weight, high performance, and is suitable for handheld use.
The position of the collector is between the meter and the concentrator, that is, the meter collector concentrator.
3、 Functions of collectors and concentrators
The collector mainly has three functions: collecting electricity meter data (such as data from different periods of peak, valley, and average), saving, uploading data through power carrier response to concentrator commands, or transmitting execution commands to the electricity meter
(If the electricity meter has the function of cutting off the user's electricity consumption).
The collector can also communicate with the manual reader on site through an infrared communication interface, accept various commands issued by the manual reader, and transmit various data recorded by the collector.
Manage 12, 32, or 64 meters through communication methods such as collecting meter pulses or RS232 (different models of collectors can be selected based on the number of meters), and then transmit these meters through power carriers
Data for_ Upload to the concentrator.
Concentrators are usually installed in one substation area, near transformers, such as distribution rooms.
