Utility Meter Communications Indicator Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Utility meters with external communications capabilities face difficulties in distinguishing between local and remote communication sessions, as the same indicator is used for both, making it challenging for users to determine if a communication session has been established with a local or remote device.
Innovation Solution
A utility meter with a meter communications indicator that uses distinct visual cues, such as different LEDs or display indicators, to differentiate between local and remote communications, allowing users to determine if the meter is communicating with a local device, a remote device, or both simultaneously.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single annunciator is used to indicate communication status for both local and remote devices, then the device complexity is reduced, but the ease of operation deteriorates because users cannot distinguish between local and remote communication sessions
Solution Approach 1:
The single annunciator is segmented into multiple distinct indicators: a first annunciator for local communication sessions and a second annunciator for remote communication sessions. This segmentation allows users to easily distinguish between different communication types while maintaining relatively simple overall device structure.
Solution Approach 2:
Different visual characteristics are assigned to different annunciators to provide local quality differentiation. The first annunciator may use one color or blinking pattern for local communications, while the second annunciator uses a different color or pattern for remote communications, enabling intuitive distinction without complex additional components.
2Ease of operation
If distinct visual indicators are provided for local and remote communications, then the ease of operation is improved, but the device complexity increases due to additional annunciators
Solution Approach 1:
The communication status indication function is segmented into separate annunciators for local and remote sessions. This segmentation improves operational clarity by providing distinct visual feedback for different communication types, while the segmentation itself is achieved through straightforward circuit design that minimizes overall complexity increase.

AI summary
A utility meter comprises a measurement circuit configured to measure consumption, a remote communications port, a local communications port, and a meter communications indicator. The meter communications indicator is configured to provide an indication that the meter is communicating with a remote device external to the meter over the remote communications port. The meter communications indicator is also configured to provide an indication that the meter is communicating with a local device external to the meter over the local communications port. The indication that communications are occurring over the local communications port is different from the indication that communications are occurring over the remote communications port. In at least one embodiment, the communications indicator is configured to provide an indication that communications are occurring simultaneously over the remote communications port and the local communications port.
