Ato parking control method compatible with different generations of vehicles

Abstract

Embodiments of the present disclosure provide an ATO parking control method compatible with vehicles of different generations. The method comprises that the ATO system generates a parking control command of the train according to the ATO target speed curve and the current speed of the train and sends it to the train; wherein, during the parking control process, the train control command is learned through iterative self-learning. According to the learned braking parameters and the difference between the train speed and the target speed, calculate the recommended speed of the train, and control the train to run at the recommended speed. In this way, the ATO vehicle control problem caused by the difference in delay parameters in the braking force establishment process of different generations of vehicles can be solved, and the problems of non-convergent vehicle speed oscillation and parking over the standard during the precise parking stage can be solved.

Description

technical field [0001] Embodiments of the present disclosure generally relate to the technical field of rail transit, and more specifically, relate to an ATO parking control method compatible with vehicles of different generations. Background technique [0002] ATO (Automatic Train Operation, automatic train operation system) is an important guarantee for the smooth operation of the train, accurate and smooth parking. ATO assists the work of ATP (Automatic Train Protection), receives information from ATP, controls the train through the traction / brake line, keeps it running at a reference speed, and realizes accurate parking. [0003] In the existing rail transit, the braking command and braking force application of the braking system (take the computer-controlled straight-through electro-pneumatic braking system as an example) still needs to go through the electro-pneumatic conversion link and the action link of compressed air, that is, the electric-pneumatic conversion link...

AI Technical Summary

Problems solved by technology

[0004] For old vehicles, the delay in the establishment of the braking force is generally high and takes a long time (1-3s). Not only is the response slow, but the control accuracy is affected by factors such as air pressure, brake cylinder friction resistance, and brake shoe performance. Great impact, unstable braking force, poor follow-up consistency, no energy-absorbing device on the line

Therefore, there are problems of over-bid and under-bid

Especially for vehicles of different generations, it cannot be compatible and realize ATO precise parking
