Departure method based on virtual annunciator

Abstract

The embodiment of the invention provides a departure method based on a virtual annunciator. The method comprises the following steps: receiving report information sent by a first-departure train; according to the report information and the data information, stored in a departure database, of the first-departure train, calculating to obtain the time required for clearing a conflict turnout by the first-departure train; taking the position of the virtual annunciator as an end point of driving permission, and calculating the time required for the speed of the following train to reach the servicebraking protection speed; calculating an optimal departure interval according to the time required for clearing the conflict turnout of the first-departure train, preset access handling time from an outbound annunciator to a virtual annunciator and the time required for the speed of the later-departure train to reach the service braking protection speed; and according to the optimal departure interval, handling an access from an outbound annunciator to the virtual annunciator for the later-departure train. In this way, it can be guaranteed that the following train is successfully departed without speed reduction, and the departing capacity of a station yard is improved.

Description

technical field [0001] Embodiments of the present disclosure generally relate to the field of rail traffic control, and more specifically, relate to a virtual signal-based departure method, device, equipment, and computer-readable storage medium. Background technique [0002] Departure capacity of a station is an important aspect to measure the transport capacity of a railway line. [0003] At present, the departure methods of different block systems are as follows: [0004] (1) Under the fixed block system, the approach road is the smallest right-of-way expropriation unit in the station. When any two lanes in the same throat area continuously depart, the train to be dispatched will clear the entire departing approach road and clear the section After that, handle the departure route for the subsequent train. [0005] (2) Under the moving block system, for two trains that need to use the same turnout (using different positions of the turnout), if figure 1 As shown in -a, w...

AI Technical Summary

Problems solved by technology

Although the conventional mobile block system only needs to clear the conflicting turnouts of the first train and unlock the conflicting turnout section, it can handle the departure route for the subsequent trains. Compared with the fixed block departure method, the departure efficiency is improved, but for large In the station yard, because of the long departure throat area and the large number of departure lanes, there is at least one overlapping section between any two departure routes, and both of them are in the turnout section, so the waiting time for the subsequent train on the lane is still long. long, affecting the starting ability
