Data Concentrator Reference Design for Smaller AMI Networks Reduces Infrastructure Cost

Design files

Overview

The TIDM-MINI-DC reference design implements a light-weight powerline communication (PLC) data concentrator (DC) solution integrated with an Ethernet repeater feature. A power grid network is static, which means that once end-nodes are installed the number of nodes to be supported by a DC is fixed. Electric utilities often have many feeder lines with only a small number of end consumers. It is not cost-effective to install a high-performance DC solution capable of supporting a large number of end nodes for these feeders. This design offers a low-cost PLC DC solution to support smaller networks with an Ethernet repeater (or edge router) feature to interconnect the local PLC network to an Ethernet-based backbone network so that a control center can control the PLC end-nodes directly.

Features
  • Supports a network up to 32 nodes with a light-weight data concentrator solution using the same platform as PLC service nodes
  • Extends network coverage with PLC/ethernet repeater (or edge router) feature interconnecting ethernet and PLC networks
  • TM4C1294 is a single-chip MCU device integrated with ethernet MAC/PHY
  • Supports both CENELEC-A and FCC frequency bands with the mini-DC solution based on TMS320F28375S and AFE032
