Embodiment Construction

[0053] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0054] When the train exits the station, traction is applied to speed A, and then it begins to coast, until the speed drops to B, and traction is reapplied to speed A... Repeat the above process until it enters the braking stage of entering the station, then starts to apply brakes and finally stops in the station parking.

[0055] In order to make ATO driving take into account the requirements of operating efficiency and energy saving, the following two energy saving methods are proposed:

[0056] 1. Adjust the speed upper limit A of applying traction. refer to figure 2 , the running time of the interval driving with the speed upper limit A② is longer than the speed up...

Abstract

The invention discloses an energy-saving control method and system of an automatic train operation system of a train and relates to the technical field of automatic driving of the train. The method comprises the following steps: S1: inquiring a database according to the service time of an interval plan to get a corresponding speed upper limit and a speed threshold of the train; S2: controlling the speed of the train by providing traction force to achieve the speed upper limit; S3: providing the traction force and removing the traction force repeatedly so as to control the speed of the train between the speed upper limit and the speed threshold; S4: providing brake force to control the speed of the train to be reduced gradually; and S5: providing the brake force which is more stable and enabling the train to be precisely and stably stopped in the preset position. As for the method, the speed upper limit and the speed threshold of the train of the ATO (automatic train operation) system can be obtained through the inquiry way, thereby reducing the complexity of the control method of the train, saving energy and being contributed to engineering implementation.

Description

technical field [0001] The invention relates to the technical field of train automatic driving, in particular to an energy-saving control method and system for a train automatic driving system. Background technique [0002] Through a lot of research at home and abroad, it is generally recognized that the automatic train driving system (ATO) should adopt the following driving strategies to achieve the purpose of energy saving: apply the maximum traction to reach the interval cruising speed when leaving the station, try to maintain a constant speed during the cruising process, and minimize the braking force. When approaching the platform, use one-time continuous braking to stop. The basic operating curve is attached figure 1 shown. [0003] The algorithm of this type of strategy is relatively fixed in the outbound traction and inbound parking phases. During the cruising process, it is necessary to adjust the traction / coasting strategy to take into account both energy saving ...
