Description

The present invention relates to an opening / closing control device for a platform door device and an opening / closing control method for the platform door device.

In recent years, the installation of platform door devices has been promoted in order to further improve safety on train platforms. The platform door device remains closed until the train enters the platform, restricting the movement of passengers from the platform side to the track side of the platform door device. When the train stops in place on the platform, the platform door device opens, allowing passengers to get on and off the train.

The platform door device is opened and closed by a crew member operating an operation panel provided at a fixed position on the track side of the platform door device (for example, Patent Document 1).

Japanese Patent No. 5764250

Normally, it is necessary to install various equipment on the platform outside the building limit based on the distance from the center of the track. Therefore, when the operation panel as described in Patent Document 1 is installed on the platform, it is necessary to separate the installation position of the platform door device from the center of the track. However, if the installation position of the platform door device is set back, the area on the platform side becomes narrow.

The present invention has been made to solve the above problems, and an object of the present invention is to provide an opening / closing control device for a platform door device and a control method for the platform door device, which can be installed without narrowing the width of the platform.

In order to solve the above problems, the present invention presents a stop position detection unit that detects the stop position of the train with respect to the platform, a plurality of optical sensors that detect the operation in a predetermined area on the platform, and a detection result of the stop position detection unit. An optical sensor switch unit that switches on / off of a plurality of optical sensors based on the above, and an opening / closing control unit that controls the opening / closing of the home door device when an operation within a predetermined area is detected by the optical sensor in the ON state. Be prepared.

According to this configuration, the open / close control device can be installed without narrowing the width of the platform.

It is a front view of the home to which the opening / closing control device of the platform door device by this embodiment is applied. It is a schematic block diagram of the opening and closing control device of the platform door device. It is a schematic perspective view of the opening / closing control device of the platform door device. It is a timing chart which shows the operation of the opening / closing control device of the platform door device. It is a flow chart which shows the operation of the opening / closing control device of the platform door device.

Hereinafter, embodiments of the present invention will be described. In the following description, an example in which the platform door device is applied to a home equipped with a full-screen platform door device will be illustrated. The opening / closing control device of the platform door device can be applied to, for example, a so-called half-height type platform door device having a high waist, regardless of the type of the platform door device.

FIG. 1 is a front view of the platform to which the opening / closing control device of the platform door device is applied, and is a view seen from the traveling direction side of the train arriving at the platform. FIG. 2 is a schematic view of a platform to which the opening / closing control device of the platform door device is applied, and shows a combination of a configuration diagram of the device and a top view of the platform. As shown in FIG. 1, a full-screen platform door device 12 having a height from the floor surface of the platform 10 to the vicinity of the ceiling is arranged on the platform 10. The platform door device 12 divides the platform 10 into a track side and a home side based on the platform door device 12. The track side is the side close to the rail 14 on which the train arrives, and is also the place where the train crew temporarily gets off while the train is stopped. Further, a certain width is secured between the platform door device 12 and the edge of the platform 10 on the track side of the platform door device 12. This is a space used for a wheelchair to pass or change the direction of the wheelchair even if there is a person standing near the platform door device 10 when the platform door device 12 is open, for example. .. Further, the platform side of the platform door device 12 is a side where passengers wait until the arrival of the train.

Passengers wait on the platform side of the platform door device 12 until the train arrives and the train door opens. When the train arrives and the crew opens the train door and platform door device 12, the train door can be accessed from the platform side. At this time, the crew once gets off the train and controls the opening and closing of the train door and the platform door device 12 on the track side of the platform door device 12.

As shown in FIG. 2, the open / close control device 16 has an optical sensor 20 for switching on / off of the stop position detection unit 18 for detecting the stop position of the train, the optical sensor 20 provided on the track side of the platform 10, and the optical sensor 20. It includes a switch unit 22 as a sensor switch unit. The opening / closing control device 16 includes a stop position detecting unit 18 and an opening / closing control unit 24 that controls the opening / closing of the platform door device 12 based on the detection result of the optical sensor 20.

The stop position detection unit 18 detects the stop position of the train arriving at the platform 10. More specifically, the stop position detection unit 18 is a plurality of stop position sensors arranged along the direction in which the home 10 extends. The stop position detection unit 18 detects the stop position of the train with respect to the platform 10. Specifically, the stop position detection unit 18 detects the stop position of a specific part of the train, such as the stop position of the first train, the stop position of the last train, and the stop position of the door. When the crew is at the end of the train, it is preferable to detect the stop position of the last train of the train. The stop position detection unit 18 may be any as long as it can estimate the position of the crew based on the information output from the stop position detection unit 18.

The optical sensor 20 is arranged at a higher position on the track side than the platform door device 12 so as not to interfere with the operation of the crew. In the illustrated example, the optical sensor 20 is supported by an arm 28 extending from a header box 26 in which the drive unit of the platform door device 12 is housed and is held above the crew. The open / close control device 16 includes a plurality of optical sensors 20, and each optical sensor 20 is installed at a plurality of locations in the direction in which the platform 10 extends in consideration of the boarding position of the train crew who is expected to arrive at the platform 10. .. For example, as shown in FIG. 2, the boarding position A1 of the crew of the 10-car train may be located behind the boarding position A2 of the crew of the 8-car train in the traveling direction. If two types of trains, 10-car train and 8-car train, are scheduled to arrive at Platform 10, the boarding position A1 of the crew of the 10-car train and the boarding position A2 of the crew of the 8-car train. The optical sensor 20 is arranged corresponding to each position of and. As a result, the operating means for performing the opening / closing control can be arranged at a position easily accessible by the crew, and the distance traveled by the crew for the opening / closing control can be shortened. Further, it is preferable that the position where the optical sensor 20 is arranged is at least deviated or separated from the flow line in which the passenger moves from the platform side of the platform door device 12 to the track side and gets on the train. The number of optical sensors 20 may be any number depending on the boarding position of the crew of the train scheduled to arrive. Of course, the present invention may be applied to platforms where only trains of one length arrive. In this case, only one optical sensor 20 is installed on the platform.

The optical sensor 20 is, for example, a reflection type sensor capable of receiving the reflected light by irradiating the floor surface of the home 10 with light having a specific wavelength in a linear downward direction in the vertical direction. The optical sensor 20 detects a change in the distance to the reflecting surface according to the return time of the reflected light, and detects the presence or absence of an object that crosses the optical axis. The optical sensor 20 is provided on the track side of the platform door device 12. Therefore, the detection result of the optical sensor 20 changes only when the only accessible crew member intentionally places an object that crosses the optical axis on the optical axis. Normally, on the track side of the platform door device 12, there is almost no object other than passengers that crosses the optical axis extending in the vertical direction. Therefore, the detection accuracy of the optical sensor 20 can be improved by directing the optical axis of the optical sensor 20 in the vertical direction.

In the embodiment, the optical sensor 20 detects a predetermined operation of the crew member. As an example, the optical sensor 20 detects an action of a crew member moving his / her hand so as to cross a light beam. When the crew's hand crosses the light beam, the light reflecting surface changes from the floor surface of the home 10 to the hand, and after the hand completely crosses the light beam, the reflecting surface returns to the floor surface of the home 10. The optical sensor 20 detects this change in the reflecting surface. It should be noted that the motion detected by the optical sensor 20 is assumed to be any motion across a light beam.

The on / off of the light irradiation by the optical sensor 20 is controlled by the switch unit 22. The switch unit 22 controls which of the plurality of optical sensors 20 the optical sensor 20 is turned on according to a predetermined condition, and controls the turned-on optical sensor 20 to be turned off according to a predetermined condition. The switch unit 22 turns on only the optical sensor 20 that is presumed to be closest to the crew according to the detection result by the stop position detection unit 18, and leaves the other optical sensors 20 off.

In the illustrated example, the motion of irradiating light linearly and crossing the optical axis is detected, but an optical sensor that irradiates spot-shaped light having an irradiation area wider than the optical axis may be used.

As shown in the drawing, the optical sensor 20 and the stop position detection unit 18 may be arranged in pairs with respect to the extending direction of the platform. In this case, for example, when the stop position detection unit 18 that detects the end of a 10-car train emits a signal, the switch unit 22 is optically on the same straight line as the stop position detection unit 18 in the width direction of the train. Turn on sensor 20.

The opening / closing control unit 24 controls the opening / closing of the platform door device 12 based on the detection result of the optical sensor 20. As an example, the open / close control unit 24 can change the open / close state of the platform door device 12 each time the optical sensor 20 detects an object crossing the optical axis. Further, as an example, the optical sensor 20 may irradiate two light rays, one for opening the platform door device 12 and the other for closing the platform door device 12. In this case, when the opening / closing control unit 24 detects a change on the light beam side for opening the platform door device 12, all the doors of the platform door device 12 are opened at the same time, and the change is made on the light beam side for closing the platform door device 12. When it is detected, all the doors of the platform door device 12 are closed at the same time.

FIG. 3 is a schematic perspective view of the open / close control device. As shown in FIG. 3, the open / close control device 16 may include a position display unit 30 indicating the position of the optical sensor 20 and a state display unit 32 indicating an on / off state of the optical sensor 20.

The position display unit 30 is, for example, a sign with characters or the like provided on the floor surface of the home 10, and informs the crew of the position where the light beam from the optical sensor 20 is irradiated. The position display unit 30 is installed directly below the optical sensor 20 in the vertical direction. The crew can cross the light beam of the optical sensor 20 by moving their hands horizontally on the position display unit 30, for example. The position display unit 30 may be a printed matter attached to the floor surface of the home 10, or an optical panel or the like may be embedded in the floor surface of the home 10.

The status display unit 32 displays the on / off status of the optical sensor 20. The state display unit 32 includes, for example, a first light 34 indicating that the optical sensor 20 is in the on state, and a second light 36 indicating that the optical sensor is in the off state. The two lights 34 and 36 light up in conjunction with the on / off state of the optical sensor 20 to inform the crew of the state of the optical sensor 20. The status display unit 32 is arranged near each of the set of the plurality of optical sensors 20 and the position display unit 30. In the illustrated example, the status display unit 32 is arranged on the wall surface of the platform door device 12 on the track side. When the first light 34 of the status display unit 32 is lit, the crew member can recognize that the optical sensor 20 corresponding to the status display unit 32 is in the ON state. The state display unit 32 may be provided with a light that emits light of two kinds of colors, and the state of the optical sensor 20 may be indicated by the color of the light. Further, the status display unit 32 may be arranged on the floor surface of the home 10 side by side with the position display unit 30. Further, one state display unit 32 may be provided on the home 10 and each optical sensor may be numbered in advance to display the number of the optical sensor 20 in the ON state on the state display unit 32.

FIG. 4 is a timing chart showing the operation of the opening / closing control device of the platform door device. When the train enters the platform 10 and stops at time t1, the sensor provided on the platform 10 detects this and turns on the stop signal. At the same time, the stop position detection unit 18 detects the stop position of the train. At about the same time, the switch unit 22 turns on the optical sensor 20 corresponding to the stop position based on the detection result of the stop position detection unit 18. This turns on the optical sensor 20 at the position most accessible to the crew. When the state display unit 32 is provided, the optical sensor 20 is turned on, and at the same time, the state display unit 32 corresponding to the optical sensor 20 is used to notify the crew member of the state of the optical sensor 20. When the crew member moves his / her hand horizontally on the position display unit 30 corresponding to the optical sensor 20 turned on at time t2 to cross the light beam of the optical sensor 20, the detection signal of the optical sensor 20 is pulsed. Stand up like a shape. When the detection signal of the optical sensor 20 rises, the open / close control unit 24 opens the platform door device 12. After the passengers have completed boarding and alighting, when the crew member again moves his / her hand horizontally on the position display unit 30 corresponding to the optical sensor 20 to cross the light beam of the optical sensor 20, the detection signal is pulsed at time t3. Stand up like a shape. The open / close control unit 24 closes the platform door device 12 at time t4 in response to the rise of the detection signal. When the train departs at time t5 and the stop signal is turned off, the switch unit 22 turns off the optical sensor 20.

FIG. 5 is a flow chart showing a series of processes by the opening / closing control device of the platform door device. When a series of processes is started, the open / close control device 16 determines in step S1 whether or not the train has stopped at the platform 10. When it is determined that the train has stopped, the open / close control device 16 detects the stop position of the train in step S2. The process of step S2 is performed using the stop position detection unit 18. Next, in step S3, the switch unit 22 turns on the optical sensor 20 corresponding to the stop position. Next, in step S4, it is determined whether or not the optical sensor 20 has detected the operation. When the crew member performs a predetermined operation on the position display unit 30 and the optical sensor 20 detects the operation, the open / close control unit 24 opens the platform door device 12 in step S5. The open state of the platform door device 12 is maintained until the optical sensor 20 detects the operation again in step S6. When the optical sensor 20 detects the operation in step S6, the open / close control unit 24 closes the platform door device 12 in step S7. Next, in step S8, the open / close control device 16 determines whether or not the train has departed. After the train departs, in step S9, the switch unit 22 turns off the optical sensor 20 and ends a series of processes.

As described above, according to the opening / closing control device 16 and the opening / closing control method according to the embodiment, the platform door device 12 can be opened and closed without providing a physical operating means such as an operation panel on the home 10. Further, by using the optical sensor 20, it is possible to prevent the space on the track side from becoming narrower than that on the platform door device 12 or the space on the home side from becoming narrower. Further, by controlling one optical sensor 20, all the doors of the platform door device can be opened and closed at the same time. Further, by arranging the plurality of optical sensors 20 along the platform 10, the distance traveled by the crew to control the opening / closing of the platform door device 12 can be shortened.

The above-described embodiment is merely an example, and each configuration of the embodiment can be appropriately changed without departing from the spirit of the present invention.

For example, the optical axis of the optical sensor 20 may be movable. In this case, for example, the detection area can be moved by moving the optical sensor 20 itself in the horizontal plane by the arm 28 or by moving the optical system in the optical sensor 20. The position of the optical axis of the optical sensor 20 is adjusted according to the actual stop position of the train. For example, when the train stops ahead of the position where it should stop, the position of the optical axis is brought closer to the boarding position of the crew. As a result, the travel distance of the crew can be reduced.
