PNC manages and controls multiple Plogg meters
Bytesnap Design
Plogg Network Controller
Bytesnap Design has developed the Plogg Network Controller (PNC), a demand response hub that centrally manages and controls multiple Plogg smart energy meters.
This will be available to view at the Embedded Systems Conference UK 2009 (ESC UK).
The Plogg energy smart meter was designed by Bytesnap Design for Energy Optimizers in 2007.
It provides essential data about energy consumption at the point of use - the electrical power socket.
The Plogg and the Plogg Network Controller provide utility companies, facilities managers or domestic users with the ability to centrally monitor energy consumption of individual electrical appliances.
The Plogg is already being trialled by utilities companies in a bid to implement technology that reduces energy waste and costs while cutting CO2 emissions.
The Plogg Network Controller can work with more than 1,000 networked Plogg wireless smart meter plugs.
Users will be able to monitor power consumption of appliances in real time, monitor consumption over an extended period and even control consumption remotely from anywhere in a building or via the internet.
A Plogg Network Controller allows users to access data and operate electrical devices via the internet.
Information from the Plogg Network Controller can be provided in Watts, VAs, current or voltage, which can be regularly downloaded from Ploggs at set intervals.
Users can access this information via the Plogg Network Controller interface.
The Plogg is based on a Teridian 6511 metering processor that can use either Zigbee or Bluetooth wireless connections.
The Network Controller software runs Windows CE with an ASP web interface, which allows customised functionality to be built in by the vendor via Java and VB scripting.
Bytesnap Design has based the network controller around an 800MHz PXA320 Swift Module from Direct Insight.
This module provides a low-cost, high performance processing solution giving enough power for users to develop complex web-based applications on the network controller.
The web server draws on data collected by an application running constantly on the controller, downloading logs from multiple Plogg devices around it and storing this information in an SQLite database to either internal or external flash.
Through custom ASP pages, the user interface and functionality of the controller can be altered to suit the end customer.
Java and VB scripting is used to allow the interface to be redesigned without changes to the controller firmware or supporting software.
