| The main aim of train traction calculation is to summarized train operation rule by analysis of the stress state of train in operation, the running test results and the experience of the real operation. The conclusion of the calculation can become the theory basis of other research on transportation problems. Many transport problem can be solved with this theory such as calculation the traction tonnage of the train, calculating and determining the speed of the train, the time of the traveling, calculating the total kinetic energy consumption, determining the number of the train on the lines, expanding the lines, reforming the transportation system and improving the locomotive traction characteristic curves.It is obviously that train traction calculation is related to the capacity, volume, cost, efficiency and security of railway, and is closely connected to many railway departments.Automatic train operation is a part of the automatic train control system, it is the highest level of the automatic train control system.The main function of it is to intelligently realize the real-time control of the train and make the train running safely in rail.It includes realizing the control of train with On-board and ground information, adjusting speed According to the situation of train route automatically, stopping the train at the station accurately and automatically. The realization of all these functions are related to ATP and ATS, which is the basis of ATO, and ATO is an advance of the two.The paper use the high-speed passenger rail line as a basic, comprehensive consideration the comfort of the passenger and the safety of the train operation, train energy-saving operation, accurate parking of the train and so on. The paper on the basis of the train traction computer theory, in combination with the CRH2's locomotive traction characteristic curves,using the computer to design of the train control algorithm, and designed the elemental point model and more point model to compare,analyzed the formation and the function of the train track target curve, those will be as a certain reference for designing the train traction software.Finally,it will be comparing the automatic train traction with the manual train traction, analyzes the advantages and shortcomings of automatic train operation system to lay the foundation for further researching of the automatic train operation system. |
