Title: Haiyong Han and Sensor-Based Train Speed Estimation
Introduction
Haiyong Han is an inventor associated with Shanghai, China. His patent work includes a method for estimating train speed from vibration signals, designed to monitor speed without relying on a dedicated speed sensor or GNSS.
Latest Patents
Han is listed as an inventor on 1 patent: “Train Speed Estimation Device and Method Based on Vibration Signals.” The invention uses two sensors to sample vibrations in a natural frequency band as a train moves. It processes the resulting signals and applies cross-correlation analysis to determine a target sampling difference, which is then used to calculate train speed. The approach is intended to provide precise, real-time speed monitoring without a speed sensor or GNSS.
Career Highlights
Han’s listed company affiliations include Aktiebolaget SKF and SKF (China) Co., Ltd. His patent reflects an application of vibration-signal analysis to railway monitoring.
Collaborations
Han’s listed coworkers include Wenjun Li and Gang Cheng.
Conclusion
Haiyong Han’s patent describes a sensor-based approach to estimating train speed from vibration signals, offering an alternative to systems that depend on dedicated speed sensors or GNSS.
