Embodiment Construction

[0045] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0046] In the actual operation organization, due to the existence of various emergencies and random disturbances, the trains in operation will deviate from the existing operation plan to a certain extent. Small. For the vehicle-mounted ATO system, the train is its control object. After the ATO speed command parameters are given, when the state of the control object changes, it will inevitably affect the control accuracy of the ATO system control.

[0047] The present invention proposes an ATO speed command energy-saving optimization method considering train precise parking factors, such as figure 1 As shown, it specifically includes the following steps:

[0048] Step 1: Establish a precise train parking model based on the multi-objective particle swarm optimization algorithm, and obtain the parking target point considering precise parking. Such as figure...

Abstract

The invention discloses an ATO speed command energy-saving optimization method considering accurate train parking factors, and the method comprises the following steps: establishing an accurate parking model, obtaining a parking target point considering accurate parking, and establishing a train operation simulation model; on the basis that the ATO speed command robustness requirement is met, establishing an ATO speed command multi-target optimization model with the niche particle swarm as the algorithm and the train operation energy consumption as the optimization target; and finally, optimizing the ATO speed command to obtain an energy-saving ATO speed command set with high similarity with the actual operation of the train. According to the ATO command set obtained through the method, possible parking distance errors are statically considered, the train can be always in a safe and controllable state range, and the method has the advantages of being low in energy consumption, high in parking accuracy and low in cost.

Description

technical field [0001] The invention belongs to the technical field of urban rail transit, and in particular relates to an ATO (Automatic Train Operation) speed command energy-saving optimization method considering train precision parking factors. Background technique [0002] With the rapid development of science and technology, the current state of urban rail transit has reached the point where the train speed has been improved and the traffic density has also been increased. While bringing convenience to the travel of the general public, it also leads to the inability of traditional manual driving to simultaneously Taking into account multiple performance indicators, the automatic control research of train system is particularly important. However, based on the fact that the urban rail transit operation system cannot be expanded immediately, the mode of driving the high-speed train by the locomotive crew can be upgraded to the automatic driving mode of the train to ensure...
