Description

The present application claims priority of Chinese Patent Application No. 201711113006.X filed on November 13, 2017 , the disclosure of which is incorporated herein by reference in its entirety as part of the present application.

TECHNICAL FIELD

The present disclosure relates to a field of automatic control technologies, and in particular, to an automatic releasing method for a locked route, and more particularly to a method and apparatus for route release in Computer Interlock (CI), and a computer storage medium.

BACKGROUND

With the rapid development of Chinese high-speed railway industry, the CTCS-2 and CTCS-3 train control systems have been practically applied to many passenger lines, which improves the automation level of train control and reduces a running interval of trains.
In order to ensure safe running of the trains and avoid accidents of the trains due to some reasons, factors such as braking distance and track are taken into full consideration; and when a train runs in a switch section of station, in order to prevent accidents of trailing, derailments and even rollover, all switches in the train running direction have to be locked at specified positions, and the switches are not allowed to rotate after being locked. In the CI process, the switches are locked in a mode of route locking section, i.e., after a route is locked, the switches in the route section are not allowed to rotate.
The length of section route locking time is closely related to the running interval of the trains, and timely release of the route section can prepare routes for following trains as soon as possible, so that the running interval can be greatly shortened. In the prior art, in order to improve station transportation efficiency, route release in CI is generally designed in a sectional release mode. When the sectional release mode is adopted, the section in the locked route should be automatically released along with normal running of the train, and the section which the train passes can be immediately provided to other trains for use, so as to improve running efficiency. However, in order to ensure driving safety, CI needs to determine by effective means whether the train normally passes through the locked section. Therefore, those skilled in the art urgently need to research and develop a method for accurately judging whether a running train normally passes through the locked section so as to maximize driving efficiency when ensuring driving safety.

SUMMARY

In view of this, the present disclosure is intended to solve the technical problem of providing a method and apparatus for route release in CI and a computer storage medium, and solves the problem in the prior art that a train is misjudged normally passes through a locked section when some track circuits are abnormal.
In order to solve the above-mentioned technical problem, a specific embodiment of the present disclosure provides a method for route release in CI, including: judging whether a train normally drives into a current locked section; if a judging result is yes, judging whether the train drives away from the current locked section; if a judging result is yes, judging whether a rear section of the current locked section is released; and if a judging result is yes, releasing the current locked section.
A specific embodiment of the present disclosure further provides a computer storage medium including a computer executing instruction. When the computer executing instruction is processed by a data processing device, the data processing device executes steps of: judging whether a train normally drives into a current locked section; if a judging result is yes, judging whether the train drives away from the current locked section; if a judging result is yes, judging whether a rear section of the current locked section is released; and if a judging result is yes, releasing the current locked section.
A specific embodiment of the present disclosure further provides an apparatus for route release in CI, including: a first judging unit, which is used for judging whether a train normally drives into a current locked section; a second judging unit, which is used for judging whether the train drives away from the current locked section when a judging result of the first judging unit is yes; a third judging unit, which is used for judging whether a rear section of the current locked section is released when a judging result of the second judging unit is yes; and a releasing unit, which is used for releasing the current locked section when a judging result of the third judging unit is yes.
According to the above-mentioned specific embodiments of the present disclosure, it can be known that the method and apparatus for route release in CI and the computer storage medium at least have following advantages: it is determined whether the train normally passes through the locked section in a three-point section check mode, i.e., only when the train normally drives into the locked section and then drives away from the locked section, the locked section can be allowed to be released, thereby avoiding misjudgment when the track circuits are abnormal; and whether the train normally passes through the locked section can be accurately determined by a state of front section and states of the rear section and the current section (the current locked section), thereby maximizing driving efficiency when ensuring driving safety.
It should be known that the general description above and the specific embodiments below merely are exemplary and interpretive, and cannot make any limit to the scope of the present disclosure.

FIG. 1 is a flow chart of Embodiment I of a method for route release in CI, as provided in detailed description of the present disclosure. As shown in FIG. 1, if a train normally drives into a current locked section and drives away from the current locked section, the current locked section is released.
In the specific embodiment shown in this drawing, the method for route release in CI includes:

S101: judging whether the train normally drives into the current locked section. In the specific embodiment of the present disclosure, in a normal case, the train sequentially passes through a rear section, the current locked section and a front section. It is determined whether the train normally drives into the current locked section from the rear section.
S102: if a judging result is yes, judging whether the train drives away from the current locked section. In the specific embodiment of the present disclosure, if the train normally enters the current locked section, it is needed to determine whether the train drives away from the current locked section (i.e., determine whether the train drives away from the current locked section and enters the front section).
S103: if a judging result is yes, judging whether the rear section of the current locked section is released. In the specific embodiment of the present disclosure, after the rear section of the current locked section is released, the current locked section can be immediately provided to other trains for use, thereby improving running efficiency.
S104: if a judging result is yes, releasing the current locked section. In the specific embodiment of the present disclosure, if the train normally drives into the current locked section and drives away from the current locked section, after the rear section of the current locked section is released, the current locked section is released.

With reference to FIG. 1, only when the train normally passes through the current locked section and the rear section of the current locked section is released, the current locked section can be released, thereby implementing automatic release of the locked section, preventing misjudgment caused by abnormality of track circuits and maximizing running efficiency when ensuring driving safety.
