Figure 1. A Basic Street Lighting Network
Because the CRD 3000 Street Light Bridge module provides both ISO/IEC 14908-
3 Control Network Protocol power line communications and IEEE 802.15.4 (2.4
GHz) radio frequency (RF) wireless communications, the street lighting network
can leverage the existing power line circuits to communicate with the luminaires,
and create small RF bridges to bypass power line gaps created service
distribution transformers. Each CRD 3000 Street Light Bridge module manages
RF communications with other CRD 3000 Street Light Bridge modules, so that
you do not need to set up and manage a complex RF network – you simply install
CRD 3000 Street Light Bridge modules to extend power line communications for
the street lighting network.
You manage and control the street lighting network using an Echelon
SmartServer, known as the Segment Controller because it controls segments of
the street lighting network. A Segment Controller can consolidate data from half
a dozen or more service distribution transformers in a municipal residential
environment, allowing you to manage and control up to 200 devices – luminaires
and CRD 3000 Street Light Bridge modules. For larger street lighting networks,
you can install additional Segment Controllers.
The Segment Controller
The Segment Controller is a SmartServer 2.0 (or later) that is configured to
manage a street lighting network. You use it to configure the power line channel
for repeating, so that each luminaire and CRD 3000 Street Light Bridge module
can forward messages to luminaires and to CRD 3000 Street Light Bridge
modules within the network. You also use the Segment Controller to define
operational schedules for the luminaires.
