Abstract

The invention discloses an operation control method of an urban rail transit train. The operation control method comprises the steps: (1) a resultant force model of the single train under three working conditions of traction, braking and coasting is established, and thus a single-train motion model based on dynamics is constructed; (2) an operation simulation model of the single train is established and comprises the train starting stage, the acceleration stage, the coasting stage, the pull-in braking stage, the stopping stage and the pull-back stage; and (3) a train group tracking operation simulation model based on a train operation plan is established and comprises the train interval tracking interval maintenance stage, the train station interval maintenance stage, the rush-hour train increasing stage and the flat-peak-stage train return stage. The complete operation process such as train starting, traction, coasting and braking condition conversion is considered, and the train interval operation time division, the whole process operation time, the operation chart period, the interval instant speed, the technical speed, the travel speed, the average operation speed, and even train energy consumption and manipulation data can be analyzed, measured and calculated according to the track, train and passenger capacity conditions.

Description

technical field [0001] The invention relates to the technical field of urban rail transit train operation planning, in particular, to an urban rail transit train operation control method. Background technique [0002] Chinese invention patent CN109377037A discloses a subway peak period setting method and system based on time-sharing train quantity sequence. The peak period setting in the operation process provides a reliable formulation method. Chinese invention patent CN107766969A discloses a large station express line layout method based on the identification of the bottleneck section of subway service capacity. Constrained by capacity, the genetic algorithm is used to determine the station where the express line of the ground bus station stops, so that the average saturation of the passenger flow section in the bottleneck section of the subway service capacity is minimized, and the contradiction between supply and demand in the bottleneck section of the subway service ca...
