Research On Security Of Automatic Hump Operations In Shenyang Railway Bureau

The accidents happened in the operations of Hump automation nearly 10 years were analyzed comprehensively, while the problems and defects of nine automatic humps in marshalling yard in the Shenyang Railway Bureau. Based on the basic theory of automated Hump control, the paper the key points of security controlled were discussed comprehensively. From the key point of operations control, overcoming the defects of automatic Hump equipment and ensuring station geometry size of plane vertical section, and other aspects, the solutions to these problems were proved. The measures and recommendations of automatic hump operational security management p were proceeded to put forward.The following main contents were discussed.(1) The purpose and significance of the research were stated and the basic control theory of automatic hump was introduced.(2 ) The typical accidents were in-depth analysis of the Shenyang Railway Bureau automatic hump past ten years. The factors of influencing automation hump operational security were found out.(3) By analyzing automatic hump speeds of nine marshalling yards, the problems of the current automatic hump systems and marshalling yard lines were pointed out.(4) By analyzing daily operations of nine marshalling yards, the defects and facts influencing operational security of the equipment of automatic humps and the lines of marshalling yards were found.(5 ) Through the above analysis, the measures were targeted to propose to improve security level of the Shenyang Railway Bureau automatic hump operations.
