Zigbee IP 6LowPan Router Home Energy Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Utilities face high costs due to peak electricity demand, and consumers lack automated solutions to shift energy usage from peak to off-peak hours, requiring manual intervention and real-time tracking.
Innovation Solution
A home energy management system with a central controller and router that communicates with energy-consuming devices, enabling automatic operation during off-peak hours and integrating with utility networks for demand response, using protocols like Zigbee and WiFi to manage energy consumption and provide real-time feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If manual operation of power consuming devices is required during off-peak times, then consumers can reduce electricity costs, but consumer convenience deteriorates and requires constant manual tracking of peak/off-peak hours
Solution Approach 1:
The system enables devices to automatically operate during off-peak hours without manual intervention. The home energy manager autonomously monitors peak/off-peak schedules and controls connected devices, allowing the system to serve itself rather than requiring constant user action.
Solution Approach 2:
The system provides real-time feedback to consumers about energy costs, peak/off-peak timing, and device operation status. This feedback mechanism enables informed automated decision-making while keeping consumers informed without requiring manual tracking.
2Productivity
If a home energy management system with automated control is implemented, then energy optimization during peak/off-peak hours is achieved, but device complexity and communication infrastructure requirements increase
Solution Approach 1:
The router is designed to handle multiple communication protocols (Zigbee, WiFi, Ethernet) and serve multiple functions including device communication, internet gateway, and energy management coordination. This multi-functionality reduces the need for separate specialized devices.
Solution Approach 2:
The home energy manager acts as an intermediary device that coordinates between utility company signals, home devices, and the router. It translates and manages communications between different protocols and devices, simplifying the overall system architecture.
3Loss of information
If real-time communication among devices and utility network is enabled, then informed energy decisions can be made, but network communication overhead and processing requirements increase
Solution Approach 1:
The system uses periodic broadcasting of peak/off-peak schedules and energy cost information rather than continuous real-time communication. Devices receive updated information at scheduled intervals, reducing communication overhead while maintaining awareness of energy conditions.
Data Source
AI summary
A system and method for managing energy of a home or other structure are disclosed. An energy management system for a home network comprises a central device controller configured to communicate with energy consuming devices, energy generation devices and storage devices at a home. Power/energy measuring devices provide consumption measurements for the home and each device to the controller. A home network router routes communications among various networks for the home. The router provides for a 6LowPan/Zigbee network to communicate with WiFi, Ethernet and the like networked devices of the home.
