Comprehensive application system for railway
passenger train operation diagram data
ABSTRACT
China's high-speed railway has developed rapidly, and it has already been networked, and the
passenger traffic has been continuously improved. In order to meet the ever-changing passenger
demand, the preparation cycle of the high-speed rail passenger train operation diagram is
shortened. The current train operation diagram computer mapping system is mainly developed for
the transportation organization mode of the existing railway, and it is difficult to fully adapt to the
frequent preparation of the high-speed railway train operation diagram. The demand for running
map changes on different dates, and the high-speed railway passenger train operation diagram is
the basis for the distribution of the line ticket, the use of the EMU and the organization of the
station, and also the basis for the comprehensive evaluation of the quality of the operation diagram
and the completion of the transportation work. Especially for the comprehensive application angle
of train operation diagram data, there is a great demand in the actual work process. However, the
current optimization of the EMU operation plan and the automatic generation of the train schedule
are still mainly done manually.
Based on the analysis of the technical and economic characteristics of the high-speed railway,
the graduation design is based on the analysis of the technical and economic characteristics of the
high-speed railway. The urgent need for the data processing and operation of the train operation
diagram on the railway station site, the completion of the point-to-point The development of a set
of computer systems. Based on the professional theory, this design realizes the automation,
informationization and process of the original manual work. This design firstly analyzes the data
structure and format on the basis of the train operation diagram data, completes the design and
construction of the train operation diagram database, and completes the database access and
information management of the system based on the established train operation diagram database.
Visualization module for module and train operation diagram data. In the visual function module
of the train operation diagram data, the paving work of the train schedule to the operation diagram
and the delineation of the train intersection are mainly completed. The delineation function of the
train intersection is essentially a combinatorial optimization problem. This design Two algorithms
are proposed: the most compact automatic delineation algorithm and the automatic delineation
algorithm under the limitation of the ability, and they are solved and realized separately, and
finally integrated into the train application data integration application system.
Finally, the main work done by the system, the innovation in the development process and the
subsequent development direction are expounded and prospected.
