Embodiment Construction

[0045] The invention provides an urban rail transit train operation optimization control simulation method and system under the condition of moving block, which is based on the speed optimization algorithm.

[0046] In the method of the present invention, the dispatching center issues a running command to the train according to the train operation diagram, that is, the operation plan. During the running process, the train transmits its own position, speed and other information to the regional controller and dispatching center through the data communication subsystem; the regional controller issues a movement authorization instruction to the train within its jurisdiction (detailed below); the train according to the movement authorization instruction And the information such as own position speed is combined with the speed optimization algorithm in the present invention, realizes the safety optimization operation of train. The above information transfers all work in the continuo...

Abstract

The invention discloses a train operation optimal control simulation method and system for an urban railway system. The method comprises the following steps: detecting the speed and location of a train at the current time step; determining the distance between the train and a tracking target; calculating the optimal target speed of the train according to a speed optimization algorithm; and calculating and updating the acceleration of the train as well as the speed and location of the train at the next time step. The system comprises a vehicle-mounted device, and the vehicle-mounted device is provided with a subsystem used for calculating the optimal target speed of the train according to the speed optimization algorithm. The method and the system provided by the invention are used for optimizing the running speed curve of the train and realizing low consumption and punctuality of train operation.

Description

technical field [0001] The invention relates to an urban rail transit train operation signal control technology. More specifically, the present invention relates to an urban rail transit train operation optimization control simulation method and system under moving block conditions. Background technique [0002] In recent years, with the continuous expansion of city scale, the problem of urban transportation energy consumption has become more and more prominent. As a kind of urban rail transit with large capacity, low energy consumption and high punctuality, its importance has become increasingly prominent. While improving the operational capacity of urban rail transit, corresponding energy-saving technologies, such as train energy-saving operation control and regenerative braking, have also received great attention. [0003] At this stage, researches on train energy-saving control systems have been theoretically accumulated to a certain extent, and most of them focus on s...
