Advanced Metering Infrastructure

The Advanced Metering Infrastructure (AMI) from Tinuten Nigeria Limited (TNL) represents a next-generation smart metering ecosystem designed to enhance efficiency, accuracy, and control across electricity, water, and gas networks.

Our AMI system seamlessly integrates multiple communication technologies — including Power Line Communication (PLC), Radio Frequency (RF), GPRS, 3G, 4G, RS485, and Ethernet — to enable reliable, real-time data exchange between meters, data concentrators, and the central management system.

🔗 How the AMI System Works

The architecture of our AMI system is flexible and built to meet diverse operational environments:

• Meter-to-Concentrator Communication:
  Meters connect to data concentrators using optional technologies such as PLC, RF, or RS485, depending on site requirements and environmental conditions.
• Concentrator-to-HES Communication:
  Concentrators then communicate with the Head End System (HES) via GPRS, 3G, 4G, or Ethernet, ensuring stable long-distance connectivity and fast data transmission.
• Common Communication Configurations:
  Our systems support a variety of configuration combinations, including:
  • PLC + GPRS → PLC between meters and concentrators, GPRS between concentrators and HES
  • RF + GPRS → RF between meters and concentrators, GPRS between concentrators and HES
  • RS485 + PLC + GPRS → RS485 between meters and collectors, PLC between collectors and concentrators, and GPRS between concentrators and HES
  This flexibility ensures optimal performance and redundancy — even in challenging network environments.

💻 Head End System (HES) & Meter Data Management System (MDMS)

At the core of our AMI solution is a web-based Head End System (HES) integrated with a powerful Meter Data Management System (MDMS).

These platforms work together to:

• Collect and manage data from thousands of meters in real time
• Support remote meter reading, configuration, and firmware updates
• Detect and report tampering, outages, or abnormal usage instantly
• Provide detailed analytics for billing, energy auditing, and loss detection

The MDMS interface offers secure, browser-based access for utility operators, ensuring transparency and full operational visibility from any location.
