China Shenhua applies for patents related to “approaching-vehicle lean-line early warning,” which assesses risk based on the spatiotemporal correlation between pedestrians, vehicles, and traffic conditions, and improves the accuracy of early warnings.

March 31, according to information released by the National Intellectual Property Administration, China Shenhua Energy Co., Ltd. has filed a patent titled “A Personnel Inclination-Line Early-Warning System and Method for When a Train Arrives at a Loading Station.” The application publication number is CN121725577A. The application number is CN202511664466.6. The publication date is March 24, 2026. The filing date is November 13, 2025. Inventors are Wang Xingzhong, He Zhenyu, Zhang Suyang, Song Zongying, Guo Jinchao, and Ma Jiankang. The patent agency is Chongqing Zhongyu Intellectual Property Agency Affairs (General Partnership). The patent agent is Lei Yonglong. Classification numbers are G08B21/02 and G08B31/00.

The patent abstract shows that this application provides a personnel inclination-line early-warning system and method for when a train arrives at a loading station. By extracting from a real-time monitoring video stream of personnel a sequence of dynamic behavioral features, and then determining initial risk values of personnel crossing the inclination line at different times during the train arrival at the loading station based on static distance features between personnel in the work area and a predefined inclination-line boundary; by using the spatiotemporal correlation between all initial risk values and the train travel trajectory data within the driving risk time window to determine a cross-dimensional association deviation between all initial risk values and the train travel trajectory data; determining a comprehensive inclination-line risk feature of the personnel after adaptively weighted adjustment of all initial risk values based on the association deviation; and sending a personnel inclination-line early-warning signal to the loading-station monitoring center based on the comprehensive inclination-line risk feature. With the方案 of this application, it is possible to improve the accuracy of personnel inclination-line early warning during train arrival at a loading station through dynamic risk assessment based on the spatiotemporal association between personnel inside the loading station and the arriving train.
