Abstract

PROBLEM TO BE SOLVED: To improve train operation efficiency while maintaining safety of a platform door by constituting a door opening means to close a door halfway in door opening action without fully opening the door when detecting an obstruction by a detecting means. SOLUTION: When a door closure command is transmitted to an individual control panel 4 individually set to each platform door, a microcomputer control device 41 receives its signal and actuates a gate drive control circuit 42 to drive a motor 6A, thus starting door closing action. When a person is caught during the closing action of the door, a door tip switch 7a is actuated, and its signal is transmitted to the microcomputer control device 41 to perform control such as changing the rotational torque of the motor 6a or rotating in the opposite direction. A second after starting reopening action, reopening action is stopped, and door closing action is restarted.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control system for a platform door installed in a station such as a subway.

[0002]

2. Description of the Related Art Conventional platform doors include, for example,
The door is equipped with a pressure sensor, etc., and when a passenger or an article is caught in the door during the door closing operation, it is detected, the door is opened until the door is completely opened, and the door is opened again. The closing operation was to start.

[0003]

However, in the above prior art, when the door is reopened, the door is reopened until the door is completely opened, and then the door is closed. The time required for the vehicle to close was remarkably long, which was a serious problem with the vehicle operation, which was basically scheduled for departure.

Accordingly, an object of the present invention is to provide a platform door control system capable of improving the train operation efficiency while maintaining the safety of the platform door.

[0005]

In order to achieve the above object, the present invention provides a detecting means for detecting an obstacle when the door is closed, and a door opening means for opening the door when the detecting means detects an obstacle. Means, a platform door control system installed on the platform of the station, when the detection means detects an obstacle, the door opening means,
It is characterized in that the door is closed during the opening of the door without fully opening the door.

Thus, the time from when a failure is detected to when the door is closed again can be reduced.

[0007]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an overall view of a platform door system.

In the system of the platform door, first, the integrated control device 3 installed in the station office 2 receives a signal indicating that the vehicle 1 has entered the platform and has stopped. After receiving the signal, a door open command signal is transmitted as data to the individual control panel 4 installed on the platform door.
Thereby, the doors 5A and 5B of the platform are opened. When the passengers get on and off, the crew sends a door closing command. After the command is received by the integrated control device, a door closing command signal is transmitted to the individual control panel 4 by data. Thereby the platform door starts to close. Doors 5A, 5B
When the door is completely closed, the door close completion signal is sent to the individual control panel 4.
To the integrated control device 3. Upon receiving the door closing completion signals of all the doors, the general control device 3 transmits a door closing completion signal to the crew. Upon receiving the signal, the crew starts the vehicle 1. FIG. 2 shows the individual control panel 4
FIG.

When a door closing command is transmitted to an individual control panel 4 individually set for each platform door, the microcomputer control device 41 receives the signal and operates a gate drive control circuit 42 to thereby control the gate drive control circuit 42. Then, the operation of driving the motor 6A and closing the door is started. If a person is pinched during the closing operation of the door, the door end switch 7A operates, and the signal is transmitted to the microcomputer control device 41, thereby changing the rotational torque of the motor 6A or rotating the motor 6A in the opposite direction. And so on.

FIG. 3 shows a mechanism diagram of the platform door.

The platform door comprises a door section 5A and a door pocket section 8, in which a motor 6A and an individual control panel 4 are incorporated. Door 5 by motor rotation
A moves along the guide rail 9 and performs an opening and closing operation. Further, a door end switch 7A is provided at the end of the door 5A, so that when a person is caught, it can be detected.

FIG. 4 shows a door closing speed pattern of the platform door. This pattern shows a pattern in which door closing is completed without any obstacle being pinched after the door closing is started. After the door closing is started, the door closing speed is in an acceleration state, reaches a steady speed in one second, decelerates after steady running for three seconds, and closes in one second.

FIG. 5 shows a door closing speed pattern of a conventional platform door. In the same mode as the state described in FIG. 4, a state is shown in which a user or the like is pinched three seconds after the door is closed, the door stops, and the door is reopened. After the reopening operation starts, the door accelerates in the direction of the door pocket,
Decelerate and complete the reopening operation after 3.5 seconds. After the re-opening operation is completed, the door re-closing operation starts, and after 5 seconds, the closing operation is completed.

[0015] After the closing operation is finally started, the closing operation is completed after a lapse of 11.5 seconds. FIG. 6 shows a door closing speed pattern of the platform door according to the present invention.
In the same mode as the state described in FIG. 4, a state is shown in which the door is stopped after being caught by a user or the like three seconds later while the door is being closed.

[0016] When the user is pinched, the door switch 7 is operated, and the detection signal and the input to the individual control panel 4 are input. By inputting the detection signal to the individual control panel 4,
The door stops immediately and starts reopening.

1 shows a case where the reopening operation is stopped one second after the reopening operation is started, and the door closing operation is performed again.

If the above is described in terms of the door moving distance, FIG.
As is clear, in this example, 0.5 m / sec × 3 sec + 1/2 × 0.5 m / sec × 2 sec =
2m, and the opening of the door is an example of 2m.
As shown in FIG. 6, when an obstacle is caught after 3 seconds, the distance closed so far is 0.5 m / sec × 2 sec + ／ × 0.5 m / sec × 2 sec =
From 1.25m, it becomes 1.25M. Since the reopening operation is performed for 1 second from the top, the moving distance in the opening direction is 1.25 m from 1/2 × 0.25 m / sec × 1 sec = 0.125 m. As a result, the required moving distance until completely closed is 0.875 m from 2m-1.125m = 0.875m.

1/2 × 0.5 m / sec × 2 sec + 0.5 m /
From sec x 0.75 sec = 0.857 m, the time to complete closing is 2.75 seconds from 2 sec + 0.75 sec = 2.75 sec.

As described above, according to the embodiment of the present invention, after the door closing operation is started, even if an obstacle is pinched, the time required to complete the door closing is 6.75.
Seconds, the door closing can be completed in a shorter time than in the conventional example of 11.5 seconds or a short time, and the effect of the present invention is remarkable.

In the above example, after the reopen operation starts,
Although the example in which the reopening operation is stopped after one second has been described, a system in which the reopening operation is stopped, for example, when the 10 cm door moves after the reopening operation starts, and the door closing operation is performed again is also possible. Thus, the same effect as the effect shown in FIG. 6 is obtained, and it goes without saying that the present invention is included in the present invention.

FIG. 7 shows a second embodiment of the present invention.

FIG. 2 is a view of a pair of left and right platform doors corresponding to the first entrance in the overall configuration diagram shown in FIG. As shown in FIG. 1, the open command and the close command are transmitted to the individual control panel 10 in the left side door pocket by data transmission from the general control device 3. In the communication between the left doors, data is transmitted from the left individual control panel 10 to the motor control panel 101B in the right door pocket. As a result, the command is transmitted to the open command, the close command, and the right door. The individual control panel 10 includes a communication control panel 102 and a motor control panel 101A, and a system in which an open command and a close command are transmitted from the communication control panel 102 to the motor control panels 101A and 101B. Has become.

The motor control panels 101A and 101B receive an open command and a close command, and perform control to rotate the motors 6A and 6B according to the command. The signals of the door end switches 7A and 7B provided at the tips of the left and right doors are transmitted to the motor control panel 101A,
The door is inverted when a door switch signal is input.

In the above system, when a person or an article is hit during the closing operation of the door, only the door detected by the door switch is inverted, and the signal is not transmitted to the other door. By doing so, the other door can continue the closing operation.

As described above, by inverting only the door on the side hit by a user or the like and continuously closing the door on the other side, useless movement of the platform door such as the motor and the door is eliminated. , The door moves smoothly. There are great effects such as energy saving.

[0027]

As described above, according to the present invention, when a user or the like is caught in the door during the closing operation of the platform door, the user can easily escape from the state where the door is caught. At the same time, the door closing operation can be completed in a short time, and there is a remarkable effect that the transportation efficiency of the train can be significantly improved.
