Latest Patents

Gehui Liu holds a patent for an "Adaptive control method and system based on train operating condition identification." This patent discloses a method that includes acquiring train operating state data under various traction conditions and calculating traction and braking performance data. An adhesion condition characteristic data set is formed, and train adhesion conditions are divided into N grades based on this data set. The current adhesion condition grade N is identified using the number of adhesion condition grades and current operating state data. This method establishes a mapping relationship between an adhesion coefficient and maximum deceleration for braking under the identified grade. By clustering and grading adhesion conditions through a clustering algorithm, the method achieves more accurate adhesion condition analysis. The adaptive generation of optimal train protection curves based on adhesion condition grades enhances the reliability and safety of train operations.
