Embodiment 1
[0096] This embodiment provides a processing flow chart of a method for automatically compiling a train diagram based on vehicle-bottom multiplexing. figure 1 As shown, it mainly includes the following steps:
[0097] Step S110: Configure the basic parameters of the actual line required for mapping, including: line information, station information, running time between stations, stop time at each station, start and end time of train operation, time points of the first and last trains, minimum departure intervals allowed by the system and The maximum departure interval, the minimum turn-back time and the maximum turn-back time allowed by the system. For example: there are J stations on the urban rail line, denoted as S sta = {1, 2, ..., J}, and the depot is connected to station 1, and the running direction from station 1 to station J is defined as the upward direction, and the running direction from station J to station 1 is defined as the downward direction.

Abstract
An embodiment of the present invention provides a method for automatically compiling a train diagram based on vehicle bottom multiplexing, which relates to the technical field of train operation control, and includes the following steps: configuring the basic parameters required for compiling the train diagram; configuring the train according to the basic parameters A running scheme; establishing a train diagram optimization model according to the basic parameters and the train running scheme; using a mixed integer linear programming algorithm to solve the train diagram optimization model, and obtaining a train diagram based on the number of trains put into operation. The invention improves the compilation efficiency of the operation diagram, and the automatically compiled train operation diagram can meet the constraint conditions such as turn-back time, safety interval, train sequence, and undercarriage operation, so as to ensure the feasibility of the operation diagram, reduce the operation cost, and reduce the waiting time of passengers. It can meet the needs of frequent adjustment of train diagrams under the refined management of urban rail systems.
Description
technical field [0001] The invention relates to the technical field of train operation control, in particular to a method for automatically compiling a train operation diagram based on vehicle bottom multiplexing. Background technique [0002] With the continuous development of the urban rail transit system, the road network structure is gradually becoming more and more complex. As of July 2015, the total mileage of urban rail transit approved by the State Council exceeded 7,300 kilometers. It is estimated that by 2020, the total mileage of urban rail transit will reach 7,395 kilometers. [0003] In the case of the increasingly large-scale development of urban rail transit, the compilation of train diagrams plays an important role as a key technology in the operation and management of urban rail transit, and its implementation directly affects all aspects of rail transit operation. [0004] At the same time, the use of trains is also closely related to the operation of urba...
