Embodiment 1

[0033] The present invention provides a figure 1 The high-speed railway operation adjustment method under the condition that the end time of the emergency shown is uncertain:

[0034] Assuming that at 9:00 a.m. on a certain day, due to a landslide, the Beijing-Shanghai high-speed railway line Zhenjiangxi-Wuxi East section is broken, and the expected recovery time is unknown, involving 6 high-speed trains, namely G325, G311, G313, G301, G303, and G305.

[0035] In the above emergency scenario, due to the unknown duration of the emergency and the interruption of the section, the road network structure is partially changed, and the transportation plan specified in the existing operation map cannot be completed. Therefore, the method proposed by the present invention can be used to adjust the operation chart.

[0036] The parameters of the above scenarios can be substituted into the high-speed railway operation adjustment model:

Abstract

The invention provides a high-speed railway driving adjustment method under the condition of uncertain emergency termination time. The method comprises the following steps of: constructing a high-speed railway operation adjustment model according to high-speed railway traffic flow space-time characteristics and railway driving constraints under an emergency; obtaining historical emergency termination time data and obtaining expected termination time as a known quantity for solving the high-speed railway operation adjustment model; and solving and optimizing the high-speed railway operation adjustment model according to the expected termination time, and adjusting the high-speed train operation diagram according to a solving result. According to the invention, speed management of the high-speed train in an emergency is considered. A high-speed railway operation adjustment model is established by taking minimization of weighted summation of a train deviation plan penalty value as a target, expected termination time obtained by analyzing termination time of historical emergencies is taken as an input quantity of the model, a final high-speed train operation adjustment diagram is obtained through optimization, and the method has the effects of high efficiency and good practicability.

Description

technical field [0001] The invention relates to the technology in the field of high-speed train dispatching control, and specifically discloses a high-speed railway traffic adjustment method under the condition that the termination time of an emergency is uncertain. Background technique [0002] The operation scheduling of high-speed railway trains plays an extremely important role in ensuring the safety, order and efficiency of high-speed railway traffic. The high-speed railway dispatching and command system has many elements, and the elements are coupled with each other, so the high-speed railway dispatching and command system has high complexity. In addition, my country has a vast territory, the largest high-speed railway network structure in the world, complex transportation organization models, and changing geological conditions and natural environments along the railway. Therefore, there are many factors that affect the safety of high-speed railways in my country. Inte...
