Abstract

A switch control method and apparatus, and a storage medium are provided, which relate to the field of urban rail transit technologies. The method includes: in a process that a train requests a target object for a switch resource, determining that the train is a train before and nearest a switch in combination with switch information sent from an object controller; when the switch is in an idle state, requesting the object controller to move the switch if it is determined that a current switch orientation of the switch is inconsistent with a switch orientation required by the train for the switch, so that the object controller controls to move the switch, and adjusts a status of the switch to a locked state after the switch is moved; and controlling the train to pass through the switch according to a response message returned by the object controller.

First claim

What is claimed is:

1 . A switch control method, applied to a train, the method comprising:
receiving switch information periodically sent by an object controller, wherein the switch information comprises a current switch state of a switch, a current switch orientation of the switch, and position information of all trains before the switch; determining whether the train is a train right before the switch according to the position information; further determining whether the current switch state of the switch is an idle state if it is learned that the train is the train right before the switch; determining, if the switch is in the idle state, whether the current switch orientation of the switch is consistent with a switch orientation required by the train for the switch; requesting the object controller to move the switch if the current switch orientation of the switch is inconsistent with the switch orientation required by the train for the switch, so that the object controller controls to move the switch, and adjusts a status of the switch to a locked state after the switch is moved; and controlling the train to pass through the switch according to a response message returned by the object controller, wherein the response message is configured to indicate that the switch has been moved and the switch has been locked, the method further comprising: further determining whether the current switch state of the switch is the locked state if it is learned that the train is not the train right before the switch; determining, if the current switch state of the switch is the locked state, whether the current switch orientation of the switch is consistent with the switch orientation required by the train for the switch; and sending a locking request for the switch to the object controller if the current switch orientation of the switch is consistent with the switch orientation required by the train for the switch, wherein the locking request is configured to instruct the object controller to control the switch to enter a status in which a plurality of trains lock the switch together.

2 . The method according to claim 1 , wherein after the controlling the train to pass through the switch according to a response message returned by the object controller, the method further comprises:
determining that the train travels away from a switch section of the switch; and requesting the object controller to unlock the switch, so that the object controller unlocks the switch and adjusts the status of the switch.

3 . The method according to claim 2 , wherein before the requesting the object controller to unlock the switch, the method further comprises:
determining whether the train is downgraded to a UT train; and performing the step of requesting the object controller to unlock the switch if the train is not downgraded to the UT train.

4 . The method according to claim 3 , further comprising:
sending a control request to the object controller through an automatic train supervision (ATS) system if the train is downgraded to the UT train, wherein the control request is configured to instruct the object controller to release the locking for the switch by the train.

5 . The method according to claim 4 , wherein after the determining, if the current switch state of the switch is the locked state, whether the current switch orientation of the switch is consistent with the switch orientation required by the train for the switch, the method further comprises:
controlling, if the current switch orientation of the switch is inconsistent with the switch orientation required by the train for the switch, the train to monitor the switch information periodically sent by the object controller until it is determined that the train is the train right before the switch according to received switch information, and requesting the object controller to move the switch when the switch is in the idle state.

6 . The method according to claim 3 , wherein after the determining, if the current switch state of the switch is the locked state, whether the current switch orientation of the switch is consistent with the switch orientation required by the train for the switch, the method further comprises:
controlling, if the current switch orientation of the switch is inconsistent with the switch orientation required by the train for the switch, the train to monitor the switch information periodically sent by the object controller until it is determined that the train is the train right before the switch according to received switch information, and requesting the object controller to move the switch when the switch is in the idle state.

7 . The method according to claim 1 , wherein after the determining, if the current switch state of the switch is the locked state, whether the current switch orientation of the switch is consistent with the switch orientation required by the train for the switch, the method further comprises:
controlling, if the current switch orientation of the switch is inconsistent with the switch orientation required by the train for the switch, the train to monitor the switch information periodically sent by the object controller until it is determined that the train is the train right before the switch according to received switch information, and requesting the object controller to move the switch when the switch is in the idle state.

8 . A switch control method, applied to an object controller, the method comprising:
receiving a moving request of a first train for a switch; determining whether the first train is a train right before the switch; further determining whether the switch is in an idle state if the first train is the train right before the switch; moving the switch according to the moving request if the switch is in the idle state; and adjusting a status of the switch to a locked state after it is detected that the switch is moved, and returning a response message to the first train, so that the first train passes through the switch, wherein the response message is configured to indicate that the switch has been moved and the switch has been locked, wherein after the returning a response message to the first train, the method further comprises: receiving a locking request of a second train for the switch; determining whether a current switch state of the switch is the locked state; and controlling, if the current switch state of the switch is the locked state, the switch to enter a status in which a plurality of trains lock the switch together.

9 . The method according to claim 8 , wherein after the returning a response message to the first train, the method further comprises:
receiving an unlocking request of the first train for the switch, releasing the locking for the switch by the first train and adjusting the status of the switch according to the unlocking request.

10 . The method according to claim 9 , wherein after the returning a response message to the first train, the method further comprises:
receiving a locking request of a second train for the switch; determining whether a current switch state of the switch is the locked state; and controlling, if the current switch state of the switch is the locked state, the switch to enter a status in which a plurality of trains lock the switch together.

11 . A switch control apparatus, applied to a train, the apparatus comprising:
a receiving module, configured to receive switch information periodically sent by an object controller, wherein the switch information comprises a current switch state of a switch, a current switch orientation of the switch, and position information of all trains before the swi
