Subway train operation adjusting method and system under late condition

Abstract

The invention relates to a subway train operation adjusting method and system under a late condition. The method comprises the steps of acquiring basic parameters in a subway system, late informationof the current moment and online operation train information of the current moment; according to the basic parameters, the late information of the current moment and the online operation train information of the current moment, determining the stopping position of the sent train and the running strategy of the train which is not sent; determining the operation state of the operating train at the next moment according to the stopping position of the sent train, the running strategy of the non-sent train, the basic parameters, the late information of the current moment and the online operation train information of the current moment; and optimally configuring available underbody resources of the subway system according to the operation state of the operating train at the next moment and theoperation data. According to the invention, automatic adjustment of the operation chart can be realized according to the late information, the underbody operation plan is reasonably changed, the influence of train late on passenger travel is reduced, and the actual operation chart cashing rate is improved.

Description

technical field [0001] The invention relates to the field of train operation organization and control, in particular to an operation adjustment method and system for subway trains under delay conditions. Background technique [0002] Metro is a mode of transportation with large capacity, low energy consumption and high punctuality rate. It can relieve ground traffic pressure and improve urban transportation capacity, and plays an important role in urban economic and social development. However, during the operation of the subway system, it will inevitably be disturbed by various factors, such as faults or emergency situations, which will cause train delays and deviations from the planned operation diagram, etc., especially during peak operating hours, train delays will spread rapidly, As a result, many trains in the system are delayed, disturbing the normal operation order and reducing the service quality. [0003] In the event of failures or emergencies during operation, s...

AI Technical Summary

Problems solved by technology

[0008] 1. Dispatchers need to manually adjust the train diagram according to their work experience and on-site conditions, and issue the adjustment results through the dispatch telephone. The work pressure is high and the handling process is cumbersome;

[0009] 2. In the process of adjusting the operation chart, various influencing factors need to be fully coordinated, and the number of decisions involved is large, especially during peak hours, so the rationality and optimality of the results cannot be guaranteed;

[0010] 3. There are individual differences in the manual adjustment of the operation diagram, and the results and efficiency of the operation diagram adjustment are not the same

[0011] 4. There are various types of faults or emergency conditions that lead to train delays, and the actual on-site conditions are complex, which has high requirements for the dispatcher's work experience and adaptability
