Research On The Automatic Hump Failure Rate Control Of Wuhan North Marshalling Yard

Railways,as the main artery of the national economic development,promote the rapid development of China's economy,and passenger and freight transportation plays important roles.Especially in the second half of 2016,Zhengzhou-Xuzhou High-speed Rail has been put into operation,Shanghai-Kunming High-speed Rail was completed,Nanning-Kunming and Kunming-Guangzhou Express Railways has been open fully,these high-speed railway lines,which are continuously built and put into operation,further shorten the time and space distance between China's more regional and key cities,and make the high-speed railway network be obviously encrypted and expanded.At this point,the total mileage of China's high-speed railway is more than 20,000 kilometers,High-speed railway mileage continue to prevail first.At the same time,the railway freight transportation,by virtue of its unique advantages of large carrying capacity,low operating cost and low energy consumption,has always been the backbone freight transportation mode in China.It has been a highlighted research topic on how to further control and lower the automatic hump failure rate of the marshalling yard and then improve the freight transportation efficiency and enhance the international competitiveness of the Sino-EU train brand to some extent.The paper regards the current situation of the automatic hump transportation organization in Wuhan North Marshalling Yard as the research object,analyzes the equipment problems appearing in the automatic hump arrival,breaking-up,aggregation,marshalling,departure,etc.,determines the control precision and maintenance standards reasonably,and guarantees the operation security and accuracy of the automatic hump vehicles.Through analyzing and evaluating the dynamic monitoring an error correction of automatic hump control,it traces the operation security of the automatic hump vehicles and finds out the key to the effective control of the automatic hump failure rate of Wuhan North Marshalling Yard.In the end,the paper makes the application analysis on the establishment of dynamic monitoring and error correction based on the tracing and investigation of the hump failures of Wuhan North Marshalling Yard in the first half of 2016,and obtains the practical effects through the site inspection.The paper findings are of important significance to effective control of automatic hump failure rate,safeguard the security of the automatic hump vehicles,thus improve the efficiency and safety of cargo transport and accuracy.
