Abstract

A train door control method and system are provided. The train door control method includes: acquiring a first train identifier and a second train identifier when multiple trains park in a platform at the same time, a door of a first train to which the first train identifier belongs being to be opened at a current time point, and a second train to which the second train identifier belongs being a train arranged behind the first train, which enters the platform and parks in the platform; and controlling the opening and closing of the door of the first train and a door of the second train at different time points respectively according to the first train identifier and the second train identifier.

First claim

What is claimed is:

1. A train door control method, comprising:
acquiring a first train identifier and a second train identifier when multiple trains park in a platform at the same time, wherein a door of a first train to which the first train identifier belongs is to be opened at a current time point, and a second train to which the second train identifier belongs is arranged behind the first train and parks in the platform; and
controlling opening and closing of the door of the first train and a door of the second train at different time points respectively according to the first train identifier and the second train identifier.

2. The train door control method according to claim 1 , wherein controlling the opening and closing of the door of the first train and a door of the second train at different time points respectively according to the first train identifier and the second train identifier comprises:
generating a first opening instruction for controlling the door of the first train to be opened according to the first train identifier, and controlling the door of the first train to be opened according to the first opening instruction;
generating a second opening instruction for controlling the door of the second train to be opened according to the second train identifier at a time point of a first preset time interval after controlling the door of the first train to be opened according to the first opening instruction;
controlling the door of the second train to be opened according to the second opening instruction;
generating a first closing instruction for controlling the door of the first train to be closed according to the first train identifier at a time point of a second preset time interval after controlling the door of the second train to be opened according to the second opening instruction, and controlling the door of the first train to be closed according to the first closing instruction;
generating a second closing instruction for controlling the door of the second train to be closed according to the second train identifier after controlling the door of the first train to be closed according to the first closing instruction; and
controlling the door of the second train to be closed according to the second closing instruction, so as to control the opening and closing of the door of the first train and the door of the second train at different time points respectively.

3. The train door control method according to claim 2 , further comprising:
sending the first train identifier to a local control panel;
detecting a first platform door matching the door of the first train; and
controlling, by the local control panel, the first platform door to be opened when controlling the door of the first train to be opened according to the first opening instruction;
or
sending the second train identifier to the local control panel;
detecting a second platform door matching the door of the second train; and
controlling, by the local control panel, the second platform door to be closed when controlling the door of the second train to be opened according to the second opening instruction.

4. The train door control method according to claim 3 , further comprising:
controlling the closing of the first platform door through the local control panel when controlling the door of the first train to be closed according to the first closing instruction;
or
controlling the closing of the second platform door through the local control panel when controlling the door of the second train to be closed according to the second closing instruction.

5. The train door control method according to claim 1 , further comprising:
updating the current time point; and
acquiring a train to be door-opened based on the updated current time point, and using the train to be door-opened as the first train, so as to control the opening and closing of doors of the multiple trains parking in the platform at different time points respectively.

6. The train door control method according to claim 1 , wherein
a number of doors of the multiple trains is less than or equal to a number of doors of the platform.

7. The train door control method according to claim 2 , wherein generating a second closing instruction for controlling the door of the second train to be closed according to the second train identifier after controlling the door of the first train to be closed according to the first closing instruction comprises:
detecting whether a signal indicating that the first train has left the platform is acquired; and
generating a second closing instruction for controlling the door of the second train to be closed according to the second train identifier when the signal is detected.

8. A train door control system, comprising a logic control circuit board and signal system SIG, wherein the logic control circuit board and signal system SIG comprises:
a first acquisition module, configured to acquire a first train identifier and a second train identifier when multiple trains park in a platform at the same time, wherein a door of a first train to which the first train identifier belongs is to be opened at a current time point, and a second train to which the second train identifier belongs is arranged behind the first train and parks in the platform; and
a control module, configured to control opening and closing of the door of the first train and a door of the second train at different time points respectively according to the first train identifier and the second train identifier.

9. The train door control system according to claim 8 , wherein the control module comprises:
a first generation sub-module, configured to generate a first opening instruction for controlling the door of the first train to be opened according to the first train identifier, and control the door of the first train to be opened according to the first opening instruction;
a second generation sub-module, configured to generate a second opening instruction for controlling the door of the second train to be opened according to the second train identifier at a time point of a first preset time interval after controlling the door of the first train to be opened according to the first opening instruction;
a first opening control sub-module, configured to control the door of the second train to be opened according to the second opening instruction;
a third generation sub-module, configured to generate a first closing instruction for controlling the door of the first train to be closed according to the first train identifier at a time point of a second preset time interval after controlling the door of the second train to be opened according to the second opening instruction, and control the door of the first train to be closed according to the first closing instruction;
a fourth generation sub-module, configured to generate a second closing instruction for controlling the door of the second train to be closed according to the second train identifier after controlling the door of the first train to be closed according to the first closing instruction; and
a first closing control sub-module, configured to control the door of the second train to be closed according to the second closing instruction, so as to control the opening and closing of the door of the first train and the door of the second train at different time points respectively.

10. The train door control system according to claim 9 , further comprising a local control panel, the control module further comprising:
a sending sub-module, configured to send the first train identifier to the local control panel;
a detection sub-module, configured to detect a first platform door matching the door of th
