AI Technical Summary

Technical Problem

The existing redundancy schemes for hydraulic systems do not cover sensors, signal chains, and actuators. The redundancy across the entire chain is insufficient, resulting in blind spots, large switching disturbances, and delayed fault diagnosis, leading to a high risk of common-cause failures.

Method used

The system employs a dual hardware and software redundancy control system across the entire chain, including dual sets of hardware and software redundancy for sensors, data acquisition modules, control modules, control mechanisms, human-machine interfaces, data storage, and communication. Combined with switching arbitration logic and execution mechanisms, it achieves rapid and seamless switching.

Benefits of technology

It achieves full-link deep redundancy in the hydraulic system, enabling fast and reliable redundancy switching, reducing the probability of common-cause failures, improving system reliability and safety, and preventing equipment downtime and safety accidents.
