Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power interfaces lack the ability to effectively monitor the health status of Broadband over Power Line (BPL) links and modems, as well as other electrical and network components, particularly in harsh environments such as airports, leading to inefficient troubleshooting and reliability issues.
Innovation Solution
A system and method that utilize sensors and a processor to collect and analyze data from BPL links at a multi-use power interface, including the use of Time Domain Reflectometer (TDR) and Frequency Domain Reflectometer (FDR) for characterizing electrical conductors, to detect changes and predict potential failures, providing real-time monitoring and alerting stakeholders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional power interfaces are used without monitoring capabilities, then device complexity is reduced, but reliability of electrical power and data communications deteriorates
Solution Approach 1:
The power interface system is designed to perform multiple functions: electrical power transmission, BPL data communications, and health status monitoring of electrical and network components. By integrating these functions into a single system, the patent improves reliability without proportionally increasing complexity, as the monitoring capabilities are built into the existing power interface infrastructure rather than requiring separate dedicated systems.
2Measurement precision
If extensive troubleshooting is performed manually, then measurement precision of faulty conditions is improved, but loss of time increases
Solution Approach 1:
The system continuously collects and stores operational data from electrical and network components before failures occur. By maintaining historical data on component health status, the system prepares diagnostic information in advance, enabling rapid identification of faulty conditions without requiring extensive manual troubleshooting when problems arise.
Solution Approach 2:
The patent implements a feedback mechanism where the system continuously monitors component health status and provides real-time information about the state of electrical and network components. This feedback loop enables automatic detection and reporting of faulty conditions, improving both the precision of fault detection and reducing the time required for troubleshooting compared to manual methods.
3Speed
If BPL technology is used for high-speed data transmission, then speed of data transfer is improved, but reliability of communication in harsh environments deteriorates
Solution Approach 1:
The patent replaces traditional mechanical or physical inspection methods with electronic and optical monitoring systems. By using sensors and detectors that measure electrical parameters, signal quality, and component health status, the system maintains reliable communication monitoring in harsh environments without the limitations of physical inspection methods that degrade under extreme conditions.

AI summary
A system includes server that performs operations including obtaining, from sensors, measurements of physical parameters related to electrical power transmission and data transfer corresponding to a Broadband over Power Line (BPL) data links and a multi-use power interface configured to be electrically and communicatively coupled to a vehicle via the BPL data links. The operations also include receiving identification and location information, and a timestamp associated with a connector of the multi-use power interface, and then storing the measurements, the identification and location information, and the timestamp. The operations further include detecting a change of the connector, and identifying trends in parameters by comparing the measurements and the identification and location information to historical data. The operations also include predicting, based on correlating the identified trends to the detected change, a pending failure of a network or electrical component, and transmitting an alert indicating the pending failure to a stakeholder.
