DCU ( Data Concentrator Unit ): A DCU will be installed
per Sub-Station, DCU is an Intelligent device with built-in RS 485 Converter/LPR
module to acquire data from MIUs & built-in GSM/GPRS to transmit
data to the Data Acquisition Server Interfaced with Data Logger PC.
MIU ( Meter Interface Unit ): MIU
is an intelligent device with built-in RS485 Converter/LPR Module connected
to an Electronic Energy Meter by means of optical port/serial communication
cord to collect data at regular intervals of time. Specially designed
secured algorithms in MIU are not only to read the meters of different
makes and models with proprietary or open domain protocols but also
for validating and transmitting the data on real time basis/on schedule/on
demand to the data concentrator unit (DCU).
Features
- Supports both CDMA and GPRS Technology (depending on the network availability at the field location).
- Supports MIOS compliant/ Modbus / IEC 62056-21/ DLMS Meters.
- IP (internet protocol) based Communication, enabling simultaneous data access from hundreds of AMRs/ DCUs (Substation Data Concentrator Unit). Secure and reliable data transfer through VPN.
- Real-time Tamper Alerts/ Event notifications to Data Centre/ Field official Mobile phones through SMS.
- On line monitoring of vital Instantaneous parameters like voltages, currents energies, powers, power factors…, Tamper events, Power quality.
- Real time Outage Alerts.
- Two way communications facilitating monitoring, control and administration.
- Inbuilt versatility to interface with any other communication medium such as CDMA PSTN, leased lines, Low power RF etc.
- Specially designed secured algorithms to detect and validate various UTILITY defined tamper conditions, supply and service violations, power outages etc.
- Buffering of data in the event of loss of communication or power interruption.
- Common Optical Probe to connect any Meter.
- Common to any field power supply (like AC , 110V,220V, 440V).
- Common to any Communication Technology (GSM, GPRS, CDMA, RF).
- Common Data Acquisition & Management Software at Server end, for any meter and for any communication technology.
