The automated system will remotely switch off the electricity through AMI system when it finds out the bill is in due, and will switch on the electricity when the bill is paid.

Architecture

DONSUN AMI system consists of Smart meter, communication modules, DCU (Data Concentrator Unit), Head End System (MDCS), Meter Data Management System (MDMS), Database, and Server.
For communication module, DONSUN has now 4 solutions

1. GSM-GPRS only

2. G3-PLC communication module with DCU (GSM-GPRS)

3. Wi-Fi / BLE mesh with GSM-GPRS module

4. LoRa

DONSUN provides communication module according to client requirement.

In GSM only option all the meters connect to the HES directly by GSM-GPRS technology. This solution is ideal for places where the cellular network is strong.

In LoRa RF network, up to 1000 meter within 2 KM open space can be connected to LoRa gateway and from LoRa gateway, 1000 meters data can be sent to HES/MDMS system using GSM or Ethernet or optical line.
All these solutions offer Ad-hoc capability. With this capability, a new meter can be installed within a quick time lapse and with ease.
