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

The embodiment of the invention provides an automatic compilation method of a train working diagram based on underbody duplexing, and relates to the technical field of train running control. The automatic compilation method includes steps of configuring basic parameters for compiling the train running diagram; configuring a train operation plan according to the basic parameters; building up an optimal model of the train working diagram according to the basic parameters and the train operation plan; applying a mixed integer linear planning algorithm to solve the optimal model of the train working diagram, and acquiring the train working diagram based on the number of the underbody in operation. The method improves the compilation efficiency of the working diagram; the automatically compiled train working diagram can meet the returning time, safety interval, train order, underbody use, and other restriction conditions, guarantee the feasibility of the working diagram, reduce the operation cost, and decrease the passenger waiting time; besides, the method can meet the demand of frequent adjustment of the train working diagram under a refined management of an urban rail system.

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...
