Overview
The gridComm GC1338 is a 3-Phase DIN Rail Hybrid
Power Line Communication (PLC)- Radio Frequency
(RF) Master Light Controller designed for Street Light
Control operations. The gridComm Master Light
Controller (MLC)
serves as a powerful concentrator and
gateway connecting a network of streetlights to the
cloud-based Street Light Management Software,
controlling and monitoring the operations of turning
on/off, dimming, scheduling, alarm events and data-
logging functions of an individual light or a group of street
lights.
The 3-phase DIN Rail Master Light Controller utilizes the
industry-leading gridComm GC2200 IC chip, an 18-
channel OFDMA (Orthogonal Frequency Division
Multiple Access) Power Line Communication
Transceiver. The 18 PLC channels are capable of
operating over a wide frequency range from 5KHz to
500KHz on the power lines whilst the 19th RF channel
operates on industrial-strength ISM frequency bands.
By taking advantage of its inherent 18 independent PLC
channels and the additional 19
th
RF channel, the
GC1338 can communicate over PLC and RF
concurrently. This brings upon the benefits of operating
in a single unified communication network using
common communication protocol, command sets and ID
addressing scheme.
With its sub-GHz RF option capability, the MLC can
communicate with plug-and-play RF battery-operated
IoT sensor nodes, such as environmental, light, pollution,
flood and proximity sensors, or any hybrid nodes which
leverage on GC-Net networking firmware using power
line network as the backbone network infrastructure. The
MLC also integrates Digital I/Os that could be connected
to an external anti-tamper or overload sensor for fail-safe
measures and motion sensors or other sensors based on
trigger events such as movements, light or sound. The
MLC is also equipped with Analog I/Os for analog signal
acquisitions from sensors such as temperature sensors,
humidity sensors, etc for further processing. In addition,
there is an on-board 4GB internal memory for storage of
historical data. The connectivity TCP link with the
backend Street Light Management Software (SLMS) is
enabled via the built-in 3G modem. The GC1338 can
automatically perform node discovery and establish
suitable repeaters to set up a robust routing network
based on a set of complex algorithms.
Figure 2 illustrates the implementation of a Smart Street
Lighting Sensor Network System using the GC1338 in
conjunction with gridComm’s Digital Power Supply (DPS)
and Street Lights Management Software.
