Data concentrator adopts advanced 32 bit ARM9 hardware platform, and the stability of embedded Linux operating system platform as the core, with mature GPRS communication technology and electric power carrier communication technology for the data link, using fully modular structure design, is an advanced technology, stable performance and reliable operation of the embedded intelligent controller products.
Data concentrator has the main function: meter reading data collecting, data of meter and data concentrator storage, data processing control, and some data statistics function. Data concentrator is also a hub device connected to the main system. Data concentrator is mainly used in low voltage electric power system automation of data acquisition, and electric power marketing system automatic meter reading.
Data concentrator meets DLMS/COSEM related standards.
- Demand data reading
- Day data reading
- Billing data reading
- Key users profile data reading
- Power quality profile reading
- Event reading
- One concentrator can manage 1024 pcs PLC meters
- Data storage period: 60 days for curve of daily data, 12 months for monthly billing data, 96 hourly curve data of 20 key user in 10 days
- Last 1024 events can be recorded in the concentrator.
- Data storage capacity is more than 32M
Data Recopy, Alarming
- Concentrator automatic meter reading fail, Concentrator has retransmission mechanism. The times of retransmission is configured, default 3
- If concentrator doesn’t read the meter in time interval, concentrator will reread meter in n times, n can be configured. If concentrator reread meter failed times more than n then concentrator will record event and send warning information to main station
Time Hack Function
- Main station can remote adjust concentrator’s time, concentrator can broadcasting adjust meters’ time
- Support daylight saving time function. Master station set the daylight saving time start time and end time, deviation, and set the daylight saving time status valid, concentrator run to set a time will automatically switch to daylight saving time
- Supports Persian and Gregorian calendars
On-site copying function
- HHU can read the concentrator data through optical port, and the data can send to master station
- Support optical port (IEC61056-21)
- Support RS485 (IEC62056-46)
- Self-diagnose & Abnormal information record
- Remote control function
- Upgrade function
- Key users Monitor
- Data Security
- Inbuilt Web server
