Signaling system and door control method

1. A signaling system comprising:

an on-board device provided in a moving vehicle traveling on a track;

a station interface device provided in a station along the track; and

a platform screen door provided in the station and controlled by the station interface device,

wherein the moving vehicle comprises:

a traveling control section configured to control the moving vehicle to travel, and

a door control section configured to control opening and closing of the platform screen door and doors of the moving vehicle,

wherein the traveling control section detects that the moving vehicle has stopped at the station,

wherein the traveling control section outputs a power running off command and a brake operation command in response to the detection of the stop,

wherein the door control section detects the power running off and the brake operation,

wherein when the door control section detects the power running off and the brake operation, the on-board device outputs a door open permission command to instruct release of a lock state of the platform screen door,

wherein the station interface device releases the lock state of the platform screen door in response to the door open permission command,

wherein after the lock state of the platform screen door is released, the on-board device outputs a door open command to instruct the opening of the platform screen door,

wherein the station interface device opens the platform screen door in response to the door open command, and

wherein the on-board device opens the doors of the moving vehicle.

2. The signaling system according to claim 1 , wherein the on-board device releases a lock state of the doors of the moving vehicle in response to the opening of the platform screen door, and opens the doors of the moving vehicle in response to the release of the lock state of the doors of the moving vehicle.

3. A door control method using a signaling system, which comprises:

an on-board device provided for a moving vehicle traveling on a track;

a station interface device provided for a station along the track; and

a platform screen door provided for the station and controlled by the station interface device,

wherein the door control method comprises:

detecting, by the on-board device, that the moving vehicle has stopped at the station;

outputting, by the on-board device, a power running off command and a brake operation command in response to the detection of the stop;

detecting the power running off and the brake operation;

outputting a door open permission command by the on-board device to instruct a release of a lock state of the platform screen door when the moving vehicle has stopped at the station and the power running off and the brake operation are detected;

releasing the lock state of the platform screen door by the station interface device in response to the door open permission command;

outputting a door open command by the on-board device to instruct the opening of the platform screen door, after the lock state of the platform screen door is released;

opening the platform screen door by the station interface device in response to the door open command; and

opening doors of the moving vehicle by the on-board device.

4. The door control method according claim 3 , wherein the opening the doors of the moving vehicle comprises:

releasing a lock state of the doors of the moving vehicle by the on-board device in response to the opening of the platform screen door; and

opening the doors of the moving vehicle by the on-board device in response to the release of the lock state of the doors of the moving vehicle.
