Design and Implementation of High Speed Overload and Unbalanced Load Detection System for Railway Freight Cars
摘要
Abstract
China's railway freight transportation is accelerating towards heavy-haul and high-speed development,with the maximum speed of freight cars generally increased to 120 km/h.The threat posed by overload and unbalanced load to transportation safety and stability has significantly intensified.To address the bottlenecks of insufficient detection accuracy and data transmission delay under high-speed conditions,prevent accidents,and ensure safe loading,this study constructed a safe freight car loading guarantee technology suitable for the 100 km/h speed range.The research broke through the challenges of high-speed dynamic weighing,deployed a high-precision sensor array,built a distributed detection network,coupled dynamic multi-measuring area data fusion algorithms,and achieved precise collection of freight car wheel load and lateral offset at speeds above 60 km/h and below 100 km/h.The data collection and preprocessing processes were optimized to reduce interference,and an innovative"edge computing+4G/5G"architecture was adopted to control the full-chain delay of detection data within 60 seconds.Relying on intelligent models to complete rapid determination of overload and unbalanced load,the overall system architecture and core metrology algorithm mechanisms were deeply analyzed.Practical application verification shows that the system has excellent performance and high reliability,enabling rapid and precise detection of overload and unbalanced load under high-speed conditions.The research results provide key technical support for preventing railway freight car high-speed overload and unbalanced load accidents and enhancing freight transportation safety and stability.关键词
