Description

Method and device for unlocking access in computer interlocking, computer storage medium

The present application claims the priority of the Chinese Patent Application No. 201711113006.

Technical field

The present disclosure relates to the field of automatic control technologies, and in particular, to a method for automatically unlocking a locked approach, and more particularly to a method and apparatus for unlocking an access in a computer interlock (CI), and a computer storage medium.

Background technique

With the rapid development of China's high-speed railway industry, the CTCS-2 and CTCS-3 train control systems have been applied to many passenger dedicated lines, which has improved the automation level of train control and reduced the train running interval.

In order to ensure the safe operation of the train and avoid the accident caused by the train for some reason, the braking distance and the line of the train are fully taken into consideration. When the train is running in the station, the train is prevented from being crushed, derailed or even dumped. When it occurs, all the switches in the running direction of the train must be locked to the specified position. After the switch is locked, the turnout is not allowed to be rotated. In the computer interlocking process, the switch is closed by means of the access locking section, that is, the switch in the access section after the access is locked is not allowed to rotate.

The length of the section access locking time is closely related to the running interval of the train. The timely unlocking of the access section can prepare the approach for the subsequent train as soon as possible, which can greatly shorten the running interval. In the prior art, in order to improve the transportation efficiency of the station, the unlocking of the access in the computer interlocking is generally designed according to the segment unlocking mode. When the segment unlocking mode is adopted, the locked middle section should be automatically unlocked with the normal operation of the train, and the section through which the train passes can be immediately provided to other trains for use, thereby improving the operation efficiency. However, in order to ensure driving safety, the computer interlock must use effective means to determine whether the train has passed the locking section normally. Therefore, those skilled in the art need to develop a method for accurately determining whether a traveling train passes normally through a locking section, thereby ensuring driving safety while maximizing driving efficiency.

Summary of the invention

In view of this, the technical problem to be solved by the present disclosure is to provide a method and device for unlocking an access in a computer interlock, and a computer storage medium, which solves the problem that some track circuits in the prior art are incorrectly judged as the train normally passes the lock. The problem with the section.

In order to solve the above technical problem, a specific embodiment of the present disclosure provides a method for unlocking an access in a computer interlock, including: determining whether a train normally enters a current locked section; if the determination result is yes, determining the train again Whether to leave the current locking section; if the determination result is yes, determine whether the rear section of the current locking section is unlocked; if the determination result is yes, the current locking section is unlocked.

Embodiments of the present disclosure also provide a computer storage medium including computer-executed instructions that, when processed by a data processing device, perform the following steps: determining whether a train is driving normally into a current locked area If the result of the determination is yes, it is determined whether the train is departing from the current locking section; if the determination result is yes, it is determined whether the rear section of the current locking section is unlocked; If so, the current locked section is unlocked.

The embodiment of the present disclosure further provides an apparatus for unlocking an access in a computer interlocking, comprising: a first determining unit, configured to determine whether a train normally enters a current locking section; and a second determining unit, configured to Determining, by the first determining unit, that the train is departing from the current locking section when the determination result is YES; and determining, by the third determining unit, that the current locking area is Whether the rear section of the segment is unlocked; the unlocking unit is configured to unlock the current locking section when the third determining unit determines that the result is YES.

According to the above specific embodiments of the present disclosure, the method and apparatus for unlocking an access in a computer interlock, and the computer storage medium have at least the following beneficial effects: determining whether the train passes through the locked section normally by using three-point detection of the section, that is, only the train Normally enter the locking section and drive away from the locking section to allow the locking section to be unlocked to avoid misjudgment caused by abnormality of the track circuit, through the front section state, the rear section and the current section (currently The locked section state can accurately determine whether the train passes normally through the locking section, and maximizes driving efficiency while ensuring driving safety.
