Handheld HAN Diagnostic Tool for Utility Meter Interoperability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Utility companies face challenges in providing advanced communication capabilities across various types of utility meters, including electricity, water, and gas, due to the need for interoperability, increased processing capabilities, and the requirement for portable devices that can communicate within large-scale Advanced Metering Systems, with existing technologies lacking a universal solution that encompasses these features.
Innovation Solution
A portable device and methodology for providing bi-directional communications within a home area network, utilizing the ANSI C12.22 protocol for open protocol communications, allowing for on-site message delivery and retrieval, and enabling selected nodes to be queried without special programming, thereby improving response times and data collection efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If utility companies implement advanced communication capabilities across various types of utility meters, then interoperability and data collection efficiency improve, but device complexity and system integration difficulty increase
Solution Approach 1:
The handheld device is designed as a universal communication tool that can interface with multiple types of utility meters (electricity, water, gas) through a single device, eliminating the need for specialized equipment for each meter type and simplifying system integration
Solution Approach 2:
The handheld device serves as an intermediary between the utility company's central system and various meter types, providing a standardized interface that mediates communication between different protocols and systems, thereby reducing integration complexity
2Loss of time
If portable devices are used for on-site communication with meters, then response time to exception reports improves, but the need for specialized programming and device configuration increases
Solution Approach 1:
The handheld device incorporates automatic device discovery and configuration capabilities, allowing it to self-configure when approaching a meter without requiring manual programming by operators, thus maintaining fast response times while eliminating programming requirements
Solution Approach 2:
The device performs automatic configuration and setup actions before actual data collection begins, pre-establishing communication parameters and protocols so that operators can immediately begin data retrieval without time-consuming programming steps
3Adaptability or versatility
If retrofits are implemented to add electronic features to existing mechanical meters, then advanced monitoring capabilities are achieved, but interchangeability and standardization are compromised
Solution Approach 1:
The solution separates the advanced electronic communication capabilities into a distinct portable handheld device rather than integrating them directly into the meter, allowing the original mechanical meters to remain unchanged and interchangeable while adding advanced functionality through the external device
Solution Approach 2:
The handheld device acts as an intermediary that bridges between existing mechanical meters and advanced monitoring systems, enabling electronic communication capabilities without modifying the original meters, thus preserving their interchangeability and standardization
