Design And Realization Of Fault Example Train Control Training System

With the development of the social economy,the construction and development of high-speed railway is developing by leaps and bounds in support of the party and the government.As of the end of 2016,China has 2503 groups of high-speed EMU.It has created more than 22,000 km operating metrage which accounting for more than 60%of the world high-speed operating metrage.Train control system is an important technical equipment for the safety of the high-speed railway.Its structure,basic function,and working principle is complicated.and it is an unprecedented challenge to the higher quality of railway workers.Only rely on the traditional way of training has been unable to meet the needs of maintenance personnel.Therefore,the research of train control training system has important significance and practical value.Firstly,this paper sorts out typical fault cases of CTCS-3 class train control system.Using the method of text classification,this paper introduces the necessity of the classification of train control fault cases.A large number of fault cases are classified,and the typical fault cases are analyzed.Secondly,this paper puts forward the functional requirements of train control training system.Based on the analysis of the structure and the main functions of the CTCS-3 train control system,the functional requirements of train control training system have been analyzed and studied.Then,the overall technical scheme of train control training system is designed in this paper,which includes three modules:fault setting module,fault recovery module and operation scene module.The fault setting module is used to design the view of the database storage cases and the database view when the fault is injected.Based on the analysis of DMI in each division,fault recovery module is used to design three layers'architecture of DMI display.The operation scene module is used to design the data model and the database of operation sequence in the yard.Finally,based on ADO.NET and other key technologies,the train control training system software was developed,tested,and carried out.Using Visual Studio 2015 as a development tool.Based on ADO.NET technology,GDI+ drawing technology and UDP communication technology,the paper realizes the development of train control training system.The completed functions include:fault case text's automatic classification and fault information injection in data base,Driver simulation,DMI's dynamic display before and after fault(fault recovery function),station display,the key steps of the train driver's description,operation,function of expected results.The training system has been tested in Beijing electricity services department of Beijing railway administration.and have excellent effect.
