Embodiment Construction
[0039] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are part of the embodiments of the present invention , but not all examples. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0040] The traditional CBTC system-based mobile block train operation mode cannot flexibly allocate the number of train vehicles to meet the needs of different capacity. Therefore, in terms of operation and management of the traditional CBTC system-based mobile block fixed-group trains, it is impossible to achieve "Dora fast running" through the "large group, high-density" operation mode duri...

The invention provides a train braking method and device, electronic equipment and a storage medium. The method comprises the steps that an ATP protection curve of a current train is determined, and the ATP protection curve is determined based on the minimum value of a ceiling EB speed limit curve, a target EB speed limit curve and a tracking EB speed limit curve of the current train, wherein the EB speed limit curve reflects the corresponding relation between each position point and the emergency braking trigger speed, the emergency braking trigger speed in the target EB speed limit curve is the trigger speed for achieving the preset target speed when braking is conducted from the corresponding position point to the target parking position point, and the emergency braking triggering speed in the tracking EB speed limit curve is the triggering speed of braking from the corresponding position point to parking at the target parking position point; and the current train is controlled to be braked based on the ATP protection curve. The current train can run according to the minimum tracking interval between the trains, and on the basis of ensuring the running density, the traffic volume is increased, the traction energy consumption is reduced, and energy conservation and emission reduction are achieved.
Description
technical field [0001] The invention relates to the technical field of rail transit, in particular to a train braking method, device, electronic equipment and storage medium. Background technique [0002] At present, in the field of rail transit operation control, there are mainly two types of train systems widely used, namely, the Chinese Train Control System (CTCS) applied to trunk railways and the communication-based train used in urban rail transit. Automatic control system (Communication Based Train Control System, CBTC). However, most of the current subway transportation systems adopt the operation mode of mobile block and fixed marshalling trains based on the CBTC system. [0003] However, the operation mode of fixed-group trains based on the CBTC system cannot flexibly allocate the number of trains to meet the needs of different capacities. Contents of the invention [0004] The present invention provides a train braking method, device, electronic equipment and s...
