The Research On The Automatic Control Model Of Humping Speed

Marshalling station always plays a crucial role in the production process of rail transport. The marshalling station efficiency and technical level measure by the hump. Many countries give much importance to strengthen the hump automation when developing the marshalling station.Automatic hump control system mainly relies on computer Main functions contain pushing the cars up the jump, automatically slip path control, slipping speed automatically control and so on. While humping speed automatic control system as the most important part of the whole progress, has important impact on efficiency and safety. Use the Traditional method "look-up table" to determine the reducer outlet speed, By deciding the levels of the cars divide the outlet speed. Under normal circumstances it can basically achieve the desired results. However, due to the limited classification, lack of precision control, and the overall adapting ability is poor, limiting effect of the speed control, affecting the operational efficiency and safety. This allows us need to find and improve the speed hump humping control model, in order to improve work efficiency and safety hump.This paper analyzes the relevant research literature and research achievements about the hump, describes the inadequacies of China’s Hump automated control systems. And ways to improve humping through automatic speed control subsystems to enhance the operating efficiency of the disintegration of the hump. Then, paper analysis the working principle and factors affect the cars disintegration and the slipping detailed. By humping speed control system and vehicle-depth understanding of the establishment of a hump humping speed control model, braking performance of three bits determine the exit velocity. Through three speed reducer export speed controls and achieving the speed controlling of entire process of slipping cars progress to realize the safety interval and safety coupling. Finally, the article also study humping speed control model and optimize speed control system configuration issues, by transfer the brake from three brake position to two brake position, realize the entire speed reducer optimization system configuration.
