Abstract

The embodiment of the invention provides a parking and door-opening control method and system for overcoming delayed response traction. The method comprises the steps of when a train is in an accurateparking stage under the control of an automatic operation system when the train enters a platform region, configuring the traction prohibition speed of the train according to the operation line parameters and the train performance parameters of the train; and if the speed of the train is lower than the configurable traction prohibition speed, stopping the automatic operation system from outputting traction to the train, and enabling the train to enter an idle running state until the train is accurately and stably stopped. According to the embodiment of the invention, configurable limited traction output threshold information is used through the automatic operation system ATO, and is used for being compatible with the electric pneumatic brake conversion speed threshold difference conditions displayed by different engineering lines due to different vehicle manufacturers, different traction brake switching and different output logics; therefore, traction output processing in an accurateparking stage in a low-speed state is completed, and the problem of parking and door-opening safety caused by delayed response traction of the train is effectively solved.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a parking door opening control method and system for overcoming delayed response traction. Background technique [0002] When the train is in the automatic train operation system (Automatic Train Operation, referred to as: ATO) vehicle control mode, due to the excessive braking 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. Respond to the train after the train stops, and output the traction after the train stops, causing the speed of the train to change to a non-zero speed state again. Since ATO starts when the train stops and stops, it will automatically open the door. However, during the door opening process, it is found that the train changes from zero speed to non-zero speed. At this time, the automatic train protection system (Automatic Train Protection...
