Study For Refinement Closed-loop Control Management Technology Of High Speed Railway Transportation Based On Position Safety Chain

The rapid development of high-speed railway, not only meets the travel needs of people, but also greatly promotes the development of regional economy. With the accelerated pace of the high-speed railway construction, China’s high-speed rail have been completed Chinese manufacturing to China to create great change, are leading China’s image to the world stage. Increasing operational mileage, extensive using of new technologies and equipment, making the high-speed rail operators has increased security risks. How to improve the railway system’s safety level, reduce accidents, has become a hot topic in the field of high-speed rail. In this paper, security issues high-speed rail system exists to comprehensively improve the scientific and high-speed rail transport, refinement, standardization management level, were closed loop study fine control technology high-speed railway, from the security risk management point of view of the high-speed railway safety explored.In this paper,"Taiyuan Railway Bureau to carry out high-speed railway personnel training plan for key positions," project practice, based on the analysis of high-speed rail jobs, combined with" chain principle ", the concept of job security chain. Gives job security chain features high-speed rail system applications, content focuses on job security chain models, including the competence, PDCA chain management practices and control of three sub-models, a total of eleven content areas for security risks below control technology research provides a theoretical basis.Based on the high-speed rail safety questionnaire Taiyuan Bureau pooled analysis combining literature, from "man-machine-ring-pipe " four levels of high-speed rail system safety factors were analyzed. As a basis for building a high-speed rail system security feature set. Using entropy theory and fuzzy AHP factors influencing the Taiyuan Bureau of High Speed Rail system security weight determination, combined with expert scoring, assessment Taiyuan Railway Bureau, the high-speed rail system safety levels overall as "general", drawn up should enhance risk management conclusions.Finally, combined with job security chain model, based on the high speed rail system establishment of safety risk closed loop management model, construct the risk classification model of support vector machine principle, classify the risk point of Taiyuan railroad bureau, in order to better risk assessment; construction of high-speed railway risk early warning model using wavelet neural network, is given. Risk warrting level in railway stations and depots, provide a basis for subsequent decisions.
