INVT Metro Traction System Product Safety Certification Research

At present,China has entered the era of urbanization,traffic congestion in large cities,especially in urban traffic congestion has become a very big headache for the Department of transportation.China faces serious "urban disease" pressure,which is more serious than any country in the process of urbanization.How to solve the traffic congestion in the central area of big cities,has become the focus of attention of all parties.According to the relevant information was informed that there are dozens of cities in the construction and planning of urban planning,urban rail climax and came,which is the need for urban development.In this paper,the rapid development of urban rail transit in China today,in the face of "asymmetric information","public goods","credit loss" phenomenon,therefore proposed the research direction and research content of this paper.INVT enterprise Metro Traction System in order to enter the market,it has passed the product safety certification.This paper mainly through the analysis of the current situation of domestic and international rail transportation products safety regulation and product safety certification system,summarizes the research and innovation of security authentication system products of city rail transportation products safety certification system under INVT Metro Traction based on the significance:first,to provide reference for the design of the relevant departments in the city rail transportation equipment products safety certification for city rail traffic evaluation;second,provide reference for independent safety assessment institutions related to the evaluation of the equipment and facilities of city rail traffic safety;third,to provide the relevant reference and reference value for the equipment supplier city rail transportation for some independent product safety certification;Fourth,for the localization of the city rail traction system it points out the way through the quick product safety certification,rapidly improve the localization The safety and reliability of traction system products,establish a new.stage for operation safety management Chinese city rail transportation industry,to escort role for the development of people's safe transportation and rail transportation industry plays.In this paper,through the analysis of the risk control mechanism,quality management theory and process control theory,and on the INVT metro traction system product safety certification status analysis,combined with risk control mechanism,quality management theory and process control theory to optimize constitute "three in one" of the INVT subway traction system product safety certification architecture.By way of literature review of previous studies report a number of researchers and scholars and papers,from the successful experience of city rail traffic safety supervision and safety certification of legal system,supervision system combing the EU and the superiority;thus the status quo of China's urban rail traffic safety situation and the safety certification;Thus proposed to the EU in the urban rail traffic safety supervision and safety certification of reference and inspiration:first,establish and improve the urban rail transit safety certification system;second,promulgated regulations of urban rail transit;third,the establishment of independent safety assessment institutions and independent.So investigation mechanism;fourth,safety risk reduced to can tolerate.In this paper,by using the risk control mechanism,the theory of quality management and process control theory,constitute the "Trinity" of the INVT metro traction system product safety certification framework.Through the empirical analysis of the "Trinity" of the INVT metro traction system product safety certification.From the elements of the system and action principle,power factor and its action principle and technical factors and the effect principle of the discusses the risk control mechanism on the INVT metro traction system product safety certification of risk identification,risk analysis and assessment,method to determine the INVT metro traction system security requirements;with target quality as the key link,to identify a quality objectives for the key process and the required resource is discussed from the aspects of quality management theory,so as to determine the INVT metro traction system requirement specification;in the use of process control theory of "seven big modules process control model" discussed the process control theory through any process and event.In the end,this paper discusses the improvement and optimization of product safety certification of INVT metro traction system by empirical method.The innovation of this paper is mainly reflected in the following aspects:First,life cycle application innovation.For the INVT product safety certification of the metro traction system operation before the life cycle take the "first after points"method,first from the "system demand distribution stage" is decomposed into "safety management life cycle" and "lifecycle quality management",and then in the "system safety confirmation and acceptance stage" together,make sure the quality and safety of products to be integrated and effective protection;Second,innovation of risk control mechanism.According to the Metro Traction System R&D and manufacturing characteristics of the risk control on the technical elements of risk principle from the original innovation,risk identification,risk analysis,risk evaluation and control process of innovation and increase the "clear environmental information","risk" and "supervision and assessment" and other key links this paper constitutes the risk control mechanism of content optimization;Third,product safety demonstration structure innovation.In this paper,the use of risk control mechanisms,quality management theory and process control theory,constitute the "Trinity" of the INVT metro traction system product safety certification framework.
