Solution Overview
Problem
Existing cable inspection and testing methods provide only snapshots in time and are not predictive of future performance, often leading to premature retirement or unsafe continued use due to the inability to account for cumulative work history and environmental exposure.

1Reliability
If traditional cable inspection methods are used, then the inspection process is simple and quick, but the ability to predict future performance and assess cumulative wear is insufficient
Solution Approach 1:
The cable system is divided into multiple monitoring points along its length, with each point equipped with sensors to measure specific parameters (tension, temperature, vibration). This segmentation allows comprehensive monitoring of cumulative wear and environmental exposure at different locations, enabling predictive analysis of future performance while maintaining manageable system complexity through modular deployment.
Solution Approach 2:
A centralized server or cloud platform acts as an intermediary between the distributed sensors and the analysis algorithms. This intermediary collects, stores, and processes data from multiple sensors, applying machine learning models to predict cable performance. The intermediary abstracts the complexity of data processing and analysis, providing predictive capabilities without requiring complex local processing at each sensor node.
2Reliability
If comprehensive sensor monitoring is implemented, then predictive analysis of cable performance is enabled, but the cost and complexity of the system increases
Solution Approach 1:
The monitoring system is designed with multi-functional sensors that can measure multiple parameters (tension, temperature, vibration, location) simultaneously at each monitoring point. This universality reduces the total number of separate sensor systems needed, lowering overall complexity and cost while enabling comprehensive predictive analysis through integrated data from multiple parameter types.
Solution Approach 2:
The system incorporates self-diagnostic and self-adjusting capabilities where sensors automatically calibrate their measurements, the system automatically identifies anomalies, and maintenance schedules are automatically optimized based on actual cable condition data. This self-service approach reduces the need for manual intervention and system configuration, effectively lowering operational complexity despite the comprehensive monitoring capability.
3Productivity
If historical data is analyzed to predict future performance, then maintenance timing can be optimized, but data processing requirements and computational complexity increase
Solution Approach 1:
The system performs preliminary data processing and feature extraction at the sensor level and in the centralized server before the data reaches the machine learning analysis stage. Historical data is pre-processed to identify patterns, trends, and anomalies, reducing the volume and complexity of data that requires sophisticated analysis. This preliminary action enables efficient predictive maintenance scheduling while minimizing computational complexity requirements.
Solution Approach 2:
The system transforms raw sensor data into meaningful parameters and features through standardized processing algorithms. By converting complex raw data into simplified, normalized parameters (such as stress cycles, temperature gradients, vibration amplitudes), the system reduces data processing complexity while maintaining the information needed for accurate predictive analysis and optimized maintenance scheduling.
