Abstract

The invention discloses a method for automatically adjusting urban rail transit train operation. According to the scheme, the situation that a train operation adjustment system is a discrete event system is taken into consideration, formal modeling is conducted on the system, and decisions are made with the total delay time of trains and the delayed train number as the indicator to select different adjustment methods to adjust the trains; after a dispatcher selects an adjustment mode according to hints at a workstation HMI, the train operation adjustment system is informed of the selected adjustment mode information through data in the JSON format; a news subscription mechanism is adopted for the train operation adjustment system and station arriving events and station departing events of online trains are obtained in a CORBA mode; a station arriving event triggering system or a station departing event triggering system of the trains enables train operation to be restored to a normal and orderly state rapidly according to the set adjustment mode. The method has the advantages of being scientific, reasonable, easy to implement, high in adjustment efficiency and practical.

Description

technical field [0001] The invention belongs to the field of urban rail traffic signal control. Background technique [0002] During the operation of urban rail transit trains, the normal operation order of the trains is often disturbed due to some special reasons, and even large-scale disturbances in the operation of the trains are caused. At this time, it is necessary to adopt certain methods or strategies to restore the train operation to a normal and orderly state. [0003] Timetable operation is currently the most commonly used operating mode for urban rail transit train operations in China, and the adjustment methods are mainly automatic timetable adjustment and manual adjustment. That is, trains running online operate according to the pre-programmed running timetable. When there is some reason that causes the train operation to deviate from the morning and evening points, the train can be restored to the timetable through automatic adjustment or manual adjustment. T...
