Abstract

A railway turnout control method comprises: constructing a data space corresponding to a railway turnout area (101); adding a virtual railway turnout, in the data space, to an area in which a target turnback stopping point is located (102); adding the virtual railway turnout to a railway turnout list corresponding to a route along which a train drives into the area (103); and not releasing claim of the virtual railway turnout when the train stops at the turnback stopping point (104); Also provided is a railway turnout control system. The method and system can solve problems of deadlock of a turnback area and insufficient safety protection of crossed routes.

2. The system of claim 1, further comprising:

an interface unit, configured to display a layout of a station or depot including the virtual railway turnout or information on claiming and releasing of the virtual railway turnout in real time.

3. A computing device, comprising at least one processor, a storage device, and a bus, wherein:

the storage device is configured to store program, the program including computer-executable instructions;

the at least one processor is coupled to the storage device via the bus; and

when the computing device is running, the at least one processor executes the program stored in the storage device, causing the computing device to implement a railway turnout control method comprising;

constructing a data space corresponding to a railway turnout area;

adding a virtual railway turnout, in the data space, to a virtual space corresponding to a turnback area in which a target turnback stopping point is located;

adding the virtual railway turnout to a railway turnout list corresponding to a route along which a train drives into the turnback area; and

maintaining claim of the virtual railway turnout when the train stops at the target turnback stopping point.

4. The computing device of claim 3, the method further comprising:

when the train drives out of the turnback area;

(i) completing, for the train, a claim process of at least one real railway turnout in a railway turnout list corresponding to a route along which the train drives out of the turnback area; and

(ii) completing, for the train, a release process of the virtual railway turnout after the at least one real railway turnout is successfully claimed.

5. The computing device of claim 3, wherein

the target turnback stopping point included in the turnback area provides a turnback for a short-routing train;

and

the adding the virtual railway turnout comprises adding the virtual railway turnout to a railway turnout list corresponding to a route along which a long-routing train passes through the turnback area.

6. The computing device of claim 3, wherein

the railway turnout area further includes crossed routes, each of which leads to a corresponding turnback area;

and

the method further comprising;

adding a first virtual railway turnout at a virtual location of the data space corresponding to a junction of the crossed routes;

for each of the turnback area, adding a second virtual railway turnout, in the data space, to a virtual space corresponding to a corresponding turnback area;

adding the first virtual railway turnout and a corresponding one of the second virtual railway turnouts to a railway turnout list corresponding to a route passing through the junction along which a train drives into a target turnback area of the turnback areas; and

maintaining the claim of the second virtual railway turnout when the train stops at a target turnback stopping point of the target turnback area.

7. The computing device of claim 6, wherein the first virtual railway turnout has a plurality of passing states, each of the plurality of passing states indicates that an establishment of a corresponding route passing through the junction is enabled.
