Research On The Safety Control Function Of Vehicle Operation In The Centralized Traffic Control System Of Existing Railway Line

In the production of railway transportation,the safety of railway is related to the national development and the safety of people’s lives and property,and the driving work is the most important part of the railway safety risk management.As the main participants in the driving work,the on-site operation safety of the depot is the key link of the whole railway safety.With the development of railway,the progress of equipment technology and the update of safety management methods and means,the train safety is developing towards a sustainable and stable situation.However,in the current safety management of each vehicle depot,how to solve the non control of staff operation and the randomness of cadre safety management has always been a difficult problem.At the present stage of railway development,the main factor affecting the safety control of train operation site is human factor.How to improve the scientific and technological level of staff operation and cadre safety management is a subject of safety management of train operation system.For this reason,the vehicle department adopts the way of formulating management methods for operation restriction and using new equipment and new technology for operation card control to solve the problem.Among them,the popularization of CTC system improves the efficiency of train operation command.However,in most of the existing operation lines in our country,even if the centralized dispatching system is equipped,its system function and structure are not perfect due to the earlier time of equipment on the road,and it does not have the function of safety card control and operation assistance in the whole process of on-site operation.In order to better meet the needs of railway transportation and adapt to the existing centralized dispatching system,how to further improve its function and structure through technical means has become an urgent problem to be solved.In this paper,the main train operation organization structure,the responsibilities and main operation contents of train operation staff at all levels,the key points in the operation process and the existing safety risks are described.Combined with the user requirements of the control system,on the basis of analyzing the user requirements and accidents,based on the utilization of resources,safety and applicability,advanced technology,high reliability and high reliability,etc Based on the principle of economy and rationality,the paper puts forward the business function,key business process and algorithm,software and hardware structure,implementation method and engineering practice route of the train operation safety control system,and makes a pilot application in a typical station.The method is feasible and the application effect is good,which provides important technical support for the effectiveness and reliability of safety management.
