Embodiment Construction

[0023] In order to make the purposes, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments These are some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Because in the ATO control mode, when the train completes the automatic entry control, especially in the scenario where the vehicle braking and deceleration is too large and the train speed and the ATO target speed deviation is too large, the ATO will output traction in the final stage of braking , the traction does not respo...

Abstract

The embodiment of the present invention provides a parking door opening control method and system for overcoming delayed response traction, including: when the train is in the precise parking stage under the control of the automatic running system and when the train enters the platform area, according to the running line parameters of the train And the train performance parameter configures the traction prohibition speed of the train; if the train speed is lower than the configurable traction prohibition speed, then stop the automatic operation system to output traction to the train, so that the train enters a coasting state until the train stops accurately. stable. The embodiment of the present invention uses configurable limited traction output threshold information through the automatic operation system ATO to be compatible with different project lines due to different vehicle manufacturers, traction brake switching and output logic differences in electro-pneumatic brake switching speed threshold differences. , so as to complete the traction output processing in the precise parking stage in the low-speed state, and effectively solve the safety problem of parking and opening the door caused by the delayed response of the train.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a parking and door opening control method and system for overcoming delayed response traction. Background technique [0002] When the train is in the automatic train operation (ATO) control mode, due to the excessive braking and deceleration of the vehicle, the deviation between the train speed and the ATO target speed is too large, and the ATO outputs traction in the final stage of braking. After the train stops, it responds to the train, so that the train stops and outputs traction, causing the speed of the train to change to a non-zero speed state again. Since ATO starts the automatic door opening operation when the train stops and stops, but during the door opening process, it is found that the train changes from zero speed to non-zero speed state. At this time, the automatic train protection system (Automatic Train Protection, ATP for short) ) Judging that the door is ...
