AI Technical Summary

Technical Problem

Existing busbar power controllers with BIT designs suffer from low reliability, delayed fault response, insufficient test coverage, and difficulty in fault isolation, making it difficult to meet the high reliability and real-time requirements of modern aircraft systems.

Method used

The intelligent busbar power controller adopts an internal self-testing method that features dual-track asynchronous initialization, state-aware dynamic testing, multi-source heterogeneous data acquisition, predictive analysis, and hierarchical early warning. Through the physical separation of monitoring and control functions and a heterogeneous monitoring architecture, it achieves the transformation from self-testing to external testing and mutual testing. It also combines independent sensors and a dedicated monitoring bus for real-time data exchange and fault prediction.

Benefits of technology

It significantly improves the speed and coverage of fault detection, reduces the false alarm rate, realizes the transformation from passive detection to active monitoring, improves system reliability and maintenance efficiency, supports fault prediction and preventive maintenance, and reduces design complexity.
