The OptiSense Processor™ (OSP) is the electronics unit
that translates the optical signals from the
OptiSensors™ into either digital or analog outputs. The
OptiSense Processor consists of optical processing
boards, a common signal processing board, and an analog
voltage output board. The optical processing boards
precondition the optical signal applied to the
OptiSensor™ and convert the optical signals received
from the OptiSensor™ into a format suitable for analysis
and processing by the digital processing board.
The digital processing board has a high-performance
digital signal processor (DSP) and a general-purpose ARM
processing core with the necessary supporting memory and
peripherals. The DSP performs the complex mathematical
operation needed to translate the optical inputs from
the OptiSensors™ into accurate voltage, current and
phase measurement values. Further processing is
performed to calculate power quality and other
power-related statistics. The general-purpose ARM
provides the control interface and supports the DNP3
protocol stack. An Ethernet port provides the DNP3
communications interface and a serial port is provided
for local configuration and monitoring.
An analog voltage output board provides voltage outputs
that are proportionally related to the line voltages and
currents. A maximum of six analog outputs are available
to support the combination OptiSensors™, providing
support for 3-phases of both voltage and current.
