Abstract
A method and device for dynamically adjusting train interval based on wide-area interlocking control, and a computer-readable storage medium. The method includes: (1) dynamically managing trains; (2) identifying a following relationship; if there is a following relationship, performing step (3), otherwise, controlling the train using existing control technology; (3) identifying weather; if the thunderstorm weather occurs, performing step (4); otherwise, adjusting the train interval by existing control technology; (4) acquiring operation states of a wireless communication system, traction power grid, traction drive system and train control system in real time; if the operation conditions are normal, performing step (5), otherwise, performing step (6); (5) independently analyzing the safety of actual following distance by the preceding and following trains in real time; performing interlocking control according to analysis results; and (6) activating a fail-safe interlocking control module to ensure dynamic and safe control of the train interval.
