Powerline communication Remote Control
& Monitoring of Public lighting and Parking lots
Real-time management of Lighting systems
Powerline communication is fast becoming an essential technology for building automation, because it enables the existence of control-oriented networks, without the need to layout extra cabling or damage & rebuild existing infrastructures, in order to install dedicated wiring.
1- Relay Hid Powerline (DOO-RT-SSR-10)
2- Powermeter (3-phases) (DOO-RT-PM-3)
3- Ground Fault Detector (PLGDF)
4- Communication Medium (Ethernet)
5- Remote Control, Monitoring & Scheduling DimOnOffT Software
6- Distribution Electrical Panel
7- USB or Ethernet Powerline-Modem (DOO-MOD-USB or DOO-MOD-Eth)
8- Powerline-RF (DOO-RT-MIO-RF) network repeater
The DimOnOff Powerline product line is ideal for enabling Remote Monitoring & Control, Scheduling, Diagnostic and Automation, by communicating with remote electrical modules, simply by utilising existing power lines of a building.
The DimOnOff system architecture simultaneously enables:
- Low-cost Advanced & Flexible Automation
- Full Control of individually adressable lights and control cabinets
- Reduced costs of control through Computerized remote administration of overall network
- Optimisation of lighting and energy management, by enforcing usage policies through automated Scheduling
- Detailed Remote Monitoring
- Ongoing analysis of network status and performance
- Optimization of maintenance through Preventive control (Cycling detection)
- Comparative data on the various network components
- Increased network operational reliability
- Increased safety with Ground Fault Detector
- Light pollution/Trespass control
DESCRIPTION
There may be tens of thousands of lighting devices in public areas, and to inspect each one is an arduous task. Wouldn't it be nice to have a system, which will automatically report if a lamp in a Public Lighting System has broken down? The infrastructure required for such self-reporting function must be very complicated and the cost prohibitively high.
DIMONOFF brings an innovative solution to this problem, with its product family of Powerline relays, sensors, keypads and modems.
Powerline communication of Control, Automation and Monitoring data runs through 120 or 347VAC electrical networks, and can if required, be interfaced with an Ethernet network to allow a local or remote computer to execute various monitoring, data acquisition, or even scheduling tasks. An analog electronic interface manages the digital signal conditioning and couples the modulated signals on the electrical powerline.
The command signals are transmitted to the different Powerline relays, controls and measurement modules through the same electrical wires that bring power to the modules to be controlled or monitored. Each module presents:
- A unique physical address (up to 4 billion addresses)
- A list of specific functionalities that it can execute, on command
- A list of Groups (logical grouping of modules) to which it belongs
- A list of Scenarios to which it will respond by executing one or more Commands.
This concept of addressability makes it possible to send remotely, on the electrical supply network, various instructions directly to the relay, control or measurement modules, and "virtualize" the process of the legacy "switch - loads to be controlled" systems, in fact eliminating the need to install new dedicated wire.
As a result, installation costs are substantially reduced, and control/automation networks are easily modified or expanded, simply by remote programming, since there is now a virtual link between all controlling and controlled modules.
The DIMONOFF Public lighting powerline modules (DOO-RT-REL-10) make use of the power cable as a communication medium and data communication can take place between two points on a power line without the need of dedicated signal wires.
A DIMONOFF powerline modem and a sensor connected at the power source of the lamp of a public lighting system can sense the current flow through the lamp, thus monitoring the operation of the lamp.
If the lamp breaks down, the relay module will report the address code of the lamp back to the monitoring station through the power cable, which will be transferred to a Data acquisition, Monitoring & Scheduling central server via a Powerline-Ethernet modem.
At the Monitoring & Control station, a signal will appear on the screen giving the location of the street lamp. A repairman can then be sent immediately to the right location to check and replace the bulb.
Using DimOnOff Powerline-Ethernet Modems, the personnel at the Monitoring & Control station can send manual or scheduled commands to remote public lighting systems, to operate the On/ Off relays of individual lamps or a particular group of lamps over Ethernet and the powerline.
