Problems solved by technology

[0005] Due to the existing mobile block train control system, when the train has entered the approach section, even if it is confirmed that the train has stopped and has not entered the access section, it still needs to go through a delay of T seconds to unlock the approach. After solving the problem of low processing time and low efficiency of other routes, the embodiment of the present invention proposes a method and device for unlocking routes

Embodiment Construction

[0048] The specific embodiments of the invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0049] figure 1 It shows a schematic flow chart of an approach unlocking method provided in this embodiment, including:

[0050] S101. After receiving the closed state of the approach entrance signal, determine whether there is a resource conflict train entering in the approach section of the approach;

[0051] Wherein, the resource conflicting trains are the trains appearing in the approach section.

[0052] Specifically, before receiving the off state of the signal machine, the following steps are also included:

[0053] A1. The on-duty staff on the ground manually confirms that the resource conflict train has stopped and has not entered the approach section. If the cond...

Abstract

The embodiment of the invention discloses an access unlocking method and device. The method comprises the steps of judging whether a resource conflict train enters an access proximity section or not after a closed state of an access entrance signal machine is received, if yes, searching for the operation state of the resource conflict train, judging whether the resource conflict train can stop stably in front of an access entrance according to the operation state, and judging whether other trains enter the access section or not if the resource conflict train can stop stably in front of the access entrance; if no other trains enter the access section, a current access is unlocked, specifically, the operation state comprises the position and operation speed of the resource conflict train. When it is determined that the train can stop stably in front of the access entrance by searching for the operation state of the train, and it is also determined that no other trains enter the access section, the current access is unlocked immediately, safety can be ensured, the access unlocking time and handling time for other accesses are shortened, and the operation efficiency of a mobile blocked train control system is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of rail transit, and in particular to a method and device for unlocking an approach. Background technique [0002] In the rail transit train operation control system, the occupancy status of the train on the track is one of the important conditions for unlocking the route. If a train is currently running in the route, it is not allowed to unlock the route at this time. Even if no train is running in the approach, if it is the closest to the entrance of the approach, the train that is about to enter the approach brakes and slows down immediately after finding that the approach is unlocked and the signal at the beginning of the approach is turned off, it is still not enough to stop before entering the approach. If parking, the access unlocking cannot be allowed for safety reasons. Before the approach entrance, a section of line section is artificially defined, which is called the approa...
