Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile network antenna arrays face challenges in monitoring and identifying faults such as physical damage, animal presence, and movement, which affect signal quality, as existing systems lack effective methods for real-time detection and alerting mechanisms.
Innovation Solution
A method and system utilizing high-resolution and thermal cameras to generate image data at intervals, compare images for differences indicative of faults, and transmit alerts when threshold conditions are met, including movement, physical damage, or elevated heat levels, with camera modules configured to monitor antenna arrays and communicate alerts through a control system and communications interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If image data is generated and compared at regular intervals to detect faults, then fault detection capability is improved, but system complexity and resource consumption increase
Solution Approach 1:
The system captures a reference image of the antenna array in a known good state before deployment. This reference image is stored and used for comparison with subsequent images to detect faults, eliminating the need for complex real-time analysis systems while maintaining reliable fault detection capability.
Solution Approach 2:
Instead of implementing complex fault detection algorithms, the system creates a simple copy (reference image) of the antenna array in its normal state and compares future images against this copy. Any significant deviations indicate faults, providing reliable detection with minimal system complexity.
2Measurement precision
If multiple camera modules are deployed to monitor different surfaces of antenna arrays, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The monitoring system is divided into multiple independent camera modules, each assigned to monitor specific surfaces or regions of the antenna array. Each camera module operates independently to detect faults in its designated area, improving overall detection precision while maintaining manageable system complexity through modular design.
3Loss of time
If image comparison is performed continuously to detect faults early, then response time is improved, but energy consumption increases
Solution Approach 1:
The system performs image comparisons at predetermined time intervals rather than continuously. This periodic operation maintains timely fault detection capability while significantly reducing energy consumption compared to continuous monitoring, achieving an optimal balance between response time and energy efficiency.
