Research On Shunting Operation Training System Of Railway Marshalling Station Based On Virtual Reality Technology

In the railway transportation system,the marshalling station is the core node.The operation of the marshalling station is relatively complicated,with various types of work,involving a lot of manpower and material resources;on-site types of work(such as shunting personnel)are dangerous,and the training of employees should not be underestimated.However,the current training concepts and methods of the railway sector are still at the level of many years ago,and cannot adapt well to the current development situation.Consider introducing VR(virtual reality technology)to make up for the shortcomings of traditional training methods.The research of this paper relies on the actual project: "VR-based railway marshalling station operation cognition and operation experimental platform",combined with my work experience at Fengtai West Marshalling Station,based on the system platform,designing training scenarios suitable for railway shunting personnel,So that the training is more in line with the actual situation,and give full play to the advantages of VR technology.The combination of VR technology and railway shunting operation training not only is not limited by time and space,but also saves a lot of training site construction costs.In addition,it also allows employees to experience and learn standardized operating procedures and traditional training in an immersive manner.Abnormal situation drills and learning can greatly improve the effectiveness of shunting personnel training.The research work of this system is as follows:The background and significance of this study and the current status of railway staff training are elaborated,then the application of virtual reality technology(VR)in the field of training is introduced and the development trend of the VR-based training system is analyzed,and finally the technical route of this article is listed.This paper analyzes the safety and training status of shunting operations at Fengtai West Marshalling Station.First,the general situation of Fengtai West Railway Station is introduced,and then the situation of Peak tail Shunting Unit is explained.Then analyze the operation safety short board of Fengtai West Station.Combined with the analysis of the safety hazards of each operation link and the age and education structure of the employees,the analysis of the global train service system and the statistical data of the safety issues of this station further illustrates that the shunting operation is a safety shortcoming in the work of the railway train service system.Finally,the staff training content and process of Fengtai West Railway Station were introduced and the existing training programs were analyzed.Conduct a demand analysis of the shunting operation training system.First,the new requirements of employees on training are explained,and then the functional requirements,framework concepts,performance requirements,and environmental requirements of the system are analyzed.Developed a VR-based shunting operation training system.First,design a scenariobased training and practice program.The designed scenario is based on the peak tail shunting operation,and the normal operation and abnormal operation scenarios and related assessment programs are designed.Then the key technologies of VR development are explained,including 3DMax modeling technology,VRay rendering technology,and Unity3 D virtual engine technology.Finally,the interface design of the training system is introduced,including the management interface,equipment resource library interface,roaming and practical exercise interface.
