Problems solved by technology
[0002] In the prior art, high-speed trains usually use traction converters to obtain power from the grid, and drive the traction motor to convert the energy obtained from the grid into kinetic energy for the train to run. When the grid is powered off, if the train needs to travel, then The train needs to use the power battery loaded on the train to provide the energy required for the train to run. Usually, there is a set of power batteries in each carriage of the train. Due to the limited energy storage of the power battery, each power battery can only provide a fixed traction The power is provided by the converter. If the traction converter fails, the power battery will be in an idle state, resulting in a waste of energy

Embodiment Construction
[0046] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts all belong to the protection scope of the present invention.
[0047] In the prior art, when the train is in the emergency traction state, if a certain traction converter on the train set fails, the power battery used to supply power to the traction converter will do no work or be in an idle state For the problem of energy waste caused by time, the application discloses a method for emergency power supply of a train set, which is applied to an emergency power supply device for a train set, see figure 1 , m...

The present application provides an emergency power supply method and system for a train set. The method includes: starting the emergency traction mode when the emergency traction signal is obtained, controlling the power battery in the emergency power supply device of the train set to supply power to the traction converter; obtaining the power supply of the train set Working condition data of the traction converter in the emergency power supply device; judging whether the traction converter is in a fault state based on the working condition data; when the traction converter is in a fault state, obtaining the emergency Identification information of the power supply device; output prompt information used to characterize the failure of the traction converter matching the identification information; judge whether a switching signal is detected, and if so, control the switching of the power battery in the emergency power supply device of the train set To the preset power supply branch of the traction converters of other trainset emergency power supply devices, when the traction converter in the trainset emergency power supply device fails, its power battery can supply power to other traction converters.
Description
technical field [0001] The invention relates to the technical field of trains, in particular to an emergency power supply method and system for a train set. Background technique [0002] In the prior art, high-speed trains usually use traction converters to obtain power from the grid, and drive the traction motor to convert the energy obtained from the grid into kinetic energy for the train to run. When the grid is powered off, if the train needs to travel, then The train needs to use the power battery loaded on the train to provide the energy required for the train to run. Usually, there is a set of power batteries in each car of the train. Due to the limited energy storage of the power battery, each power battery can only provide a fixed traction The converter provides power, and if the traction converter fails, the power battery will be in an idle state, resulting in a waste of energy. Contents of the invention [0003] In view of this, the embodiment of the present in...
