DCU creates the necessary network infrastructure by linking several Gas/water metering units to the central utility server. It receives the data from the group MUI’s in the network and transfers all data to the configured Remote Data Server through GPRS Link. The data concentrator also synchronizes time and date of metering units to the central utility server and enables secure data transfer of user authentication. One DCU will be required for each Network Group, which can have up to 1024 metering units. DCU is an intelligent device with built-in 865MHz RF Tarang UT-20 module to acquire data from Gas Metering units with built-in GPRS to transmit data to the Data Acquisition Server Interfaced with Data Logger PC. FEATURES Upstream communication to the Central Serveron GPRS/GSM and Downstream to the Meters Interface Units. Manage upto 1024 metering Nodes. Installed in the customers it eco-located with a Gas distribution. Automatically discover and add new Meterson installation. Collect and report the data including consumption,Tamper,unused. Store Upto 90 days meter data in the SD Card memory. Maintain mesyncwithmetersandServer. Monitor and report the and not working from meters. DCU will always receive the consumption details from each Meter in gun it in the network. Communicates with the Central server database using FTP server through GPRS. Download Tariff tables and configurationof Devices from SD Card. Receive every 6/12/24 Hours consumption from the Meters under its network. Detect Device failures and logs the same. Monitor the health and opera on of the devices. Real- me Tamper Alerts/Event notifications to Data Centre. Specially designed secured algorithms to detect and validate various UTILITY defined tamper conditions, supply and service violation sets.

Electrical Power has become indispensable to human survival and progress. Increasing gap between demand and supply made every other nation explore ways and means to enhance Power Generation capabilities from both conventional and non-conventional means. Apart from efforts to meet growing demand, mounting AT&C losses in distribution is another challenge being faced by utilities world wide. Specifically developing countries owe to lack of proper energy accounting from infrastructural, technological shortfalls and manual interventions in energy billing. In the wake of technology upgradation and automation in the Energy Distribution, Automated Meter Reading (AMR) or Meter Data Acquisition and Management assumes importance in enabling the utilities to gather business and operational intelligence, through collection of base line data to analysis, monitor and manage operations in AT&C losses reduction

A DCU is usually installed in a sub-station. It is an intelligent device with built-in LPR modules to acquire data from Electronic Energy Meters or MIUs using AMR Software. Its’ in-built 2G 3G module then transmits data to the Data Acquisition Server Interfaced with Data Logger PC. A Meter Interface Unit (MIU) is connected to Electronic Energy Meters and enables wireless transmission of data from meters to DCUs. It eliminates conventional cabling requirements between meters and DCUs, thereby ensuring a quantum jump and data integrity of the system.
