Application of Article 30, Paragraph 2 of the Patent Act Research meeting name JR West Group Technology Development Results Presentation 2018 Organizer West Japan Railway Company Date August 8, 2018

The present invention relates to platform barrier systems in railway stations.

At a railway station, there is a platform (platform) provided with a platform fence. The platform fence, also called a safety fence, is provided near the edge of the platform on the platform so as to extend in the longitudinal direction of the platform. At the platform where the train stops, the platform fence has a movable fence that can be opened and closed. A train is usually operated as a train composed of a plurality of cars. A movable fence is provided corresponding to each door of the stopped vehicle. The housing of the device that opens and closes the movable fence also serves as part of the fixed fence. Movable fences include movable platform fences and lifting platform fences. In the movable platform fence, a door (fence) called a platform door opens and closes in the lateral direction (see Patent Document 1, for example). A lift-type platform fence opens when a rope (fence) rises and closes when the rope descends (see Patent Document 2, for example).

At a platform where trains with different numbers of cars (number of cars forming one train) stop, it is necessary to open only the movable fence at the position where the cars stop.

Conventionally, there is known a platform door system that detects vehicles with a vehicle detection sensor, determines the number of cars in the train set, and permits the opening and closing of platform doors (fences) according to the number of cars in the train set (see Patent Document 1). This vehicle detection sensor is an ultrasonic sensor arranged on the track side of the platform door door pocket (see paragraphs [0022], [0023], FIGS. 4 and 5 of the same document).

However, in such a platform door system, as the number of cars in the train set increases, the number of vehicle detection sensors must be increased, which complicates the hardware configuration of the system and increases the cost. Further, since the vehicle detection sensor detects the vehicle body in front of the door pocket for the platform door, even if the vehicle detection sensor detects the vehicle body when the stop position of the train is deviated, the door of the vehicle does not always exist at the position corresponding to the platform door.

It is an object of the present invention to solve the above problems and to provide a platform fence system that opens a movable fence corresponding to the door of a stopped vehicle with a simple configuration even on a platform where trains of different numbers of trains stop.

A platform fence system of the present invention is a system comprising movable fences provided on a platform corresponding to each door of a vehicle that stops, a driving unit that opens and closes each of the movable fences, and a control unit that controls the plurality of driving units. A vehicle detection area for detecting the presence or absence of a vehicle in front of the movable fence on the track side is further set in the sensor from the edge of the platform to the track side, and when the track detection sensor detects that the lead vehicle has stopped within a predetermined position range, the control unit determines the number of cars in the formation based on the presence or absence of vehicles detected by the plurality of obstacle sensors, and outputs permission to open the movable fence corresponding to the door of the stopped car to the drive unit according to the determined number of cars in the formation.

In this platform fence system, it is preferable that the control unit preliminarily stores information about the number of cars in the train set that will stop, and determines the number of cars in the train set based on the presence or absence of a vehicle detected by the obstruction sensor for the movable fence corresponding to the rearmost door of the train set for each possible number of cars in the train set, and if there is a movable fence one behind the movable fence, the obstacle sensor for the movable fence.

In this platform fence system, the control unit may determine the number of cars in the formation based on the presence or absence of vehicles detected by all of the obstacle sensors.

In this platform fence system, it is preferable to have a notification unit for notifying an alarm, and when an object is detected in the obstacle detection area while the movable fence is closed, the control unit causes the notification unit to issue an alarm.

In this platform fence system, it is preferable that the obstacle sensor is a 3D sensor that detects an object in a predetermined space area.

In this platform fence system, it is preferable that the on-track detection sensor is a ranging sensor provided on the ground side.

According to the platform fence system of the present invention, the obstacle sensor provided for detecting an object between the movable fence and the edge of the platform detects the presence or absence of a vehicle in front of the movable fence on the track side, so the number of cars in the formation can be determined without increasing the number of sensors, and the movable fence corresponding to the door of the stopped vehicle can be opened.

A platform fence system according to an embodiment of the present invention will be described with reference to FIGS. 1 to 4. FIG. As shown in FIG. 1, the platform fence system 1 includes movable fences 2a, 2b, 2c, . Each of the movable fences 2a, 2b, 2c, . Each drive part 3a, 3b, 3c,..., 3d, 3e respectively opens and closes each movable fence 2a, 2b, 2c,..., 2d, 2e. The control unit 4 controls a plurality of driving units 3a, 3b, 3c, . . . , 3d, 3e. In addition, the movable fences 2a, 2b, 2c, . The drive units 3a, 3b, 3c, . The number of movable fences 2 and drive units 3 is not limited.

The platform fence system 1 is provided with an on-track detection sensor 5 . Further, the platform fence system 1 includes obstruction sensors 6a, 6b, 6c, . . . , 6d, 6e for the movable fences 2a, 2b, 2c, . The obstacle sensors 6a, 6b, 6c, .

As shown in FIG. 2, the on-track detection sensor 5 is a sensor for detecting that the leading vehicle F has stopped within a predetermined position range L. As shown in FIG.

As shown in FIG. 3, the obstacle sensor 6 is a sensor in which an obstacle detection area 61 for detecting an object between the movable fence 2 and the platform edge E is set.

As shown in FIG. 4 , the obstacle sensor 6 for each movable fence 2 is further set with a vehicle detection area 62 . The vehicle detection area 62 is set on the track side (right side in FIG. 4) from the platform edge E to detect the presence or absence of a vehicle in front of the movable fence 2 on the track side.

Each component of the platform fence system 1 will be further detailed. A platform fence system 1 is provided at a railway station. In this embodiment, the movable fence 2 is movable, and the platform doors open and close in the lateral direction (see FIG. 4). The housing of the drive unit 3 also serves as a fixed fence. The movable fence 2 and the fixed fence are provided near the edge E of the platform P so as to extend in the longitudinal direction of the platform.

The control unit 4 has a CPU (Central Processing Unit), memory, etc., and operates by executing a program (see FIG. 1).

The on-track detection sensor 5 is a distance measuring sensor provided on the ground side, and is provided outside the construction gauge. A building gauge is a railroad limit that restricts the construction of a building (see JIS E1001:2001). Its ranging sensor measures the distance to the lead vehicle. The measurement result is output to the control section 4 . When the train enters the station, the leading vehicle F reflects the laser beam emitted by the on-track detection sensor 5, so the distance to the leading vehicle F is measured (see FIG. 2). When the distance does not change, it is detected that the leading vehicle F has stopped. When the leading vehicle F is stopped in a predetermined position range L, the train having the leading vehicle is in a state of being on the line at the station. The sensor is called a locator sensor because it detects that state.

The obstacle sensor 6 is a 3D sensor that detects an object in a predetermined space area, and is provided on the track side of the housing of the drive unit 3 (see FIG. 3). The predetermined space area is a rectangle between the movable fence 2 and the platform edge E in a plan view, and a rectangular parallelepiped whose height range is generally from the platform surface to the upper end of the movable fence 2 . The 3D sensor is, for example, a TOF (Time of Flight) system, and detects an object in a predetermined space area by measuring a distance while scanning with a laser. The 3D sensor method is not limited to this. The obstacle sensor 6 in which the obstacle detection area 61 is set is basically provided in the platform fence system 1 as a safety device to ensure the safety of passengers.

The platform fence system 1 has a reporting unit 7 for reporting an alarm (see FIG. 1). The notification unit 7 is a device that notifies the staff of an alarm using light or sound. When an object is detected in the obstacle detection area 61 while the movable fence 2 is closed, the control unit 4 causes the notification unit 7 to issue an alarm. As a result, the attendant can know that a passenger or baggage is left between the movable fence 2 and the edge E of the platform.

The obstacle sensor 6 of this embodiment has two detection areas, an obstacle detection area 61 and a vehicle detection area 62 (see FIG. 4). The sensing area of the 3D sensor is set by firmware. Therefore, setting the vehicle detection area 62 to the obstacle sensor 6 in which the obstacle detection area 61 is set is performed by rewriting the firmware of the obstacle sensor 6 . In addition, the obstacle sensor 6 may be set to have one detection area including the obstacle detection area 61 and the vehicle detection area 62, and the controller 4 may determine whether the object is in the obstacle detection area 61 or the vehicle detection area 62 based on the position of the detected object. Since the vehicle detection area 62 is set on the track side from the platform edge E, what is detected in this area is a vehicle. In this case, when the head vehicle F is detected to have stopped in the predetermined position range L by the on-track detection sensor 5, the door of the vehicle is present in the vehicle detection area 62, and the door is present in front of the movable fence 2 on the track side.

The operation of the platform fence system 1 configured as described above will be described. When the on-track detection sensor 5 detects that the leading vehicle F has stopped within a predetermined position range L (see FIG. 2), the control unit 4 determines the number of cars in the formation based on the presence or absence of vehicles detected by the plurality of obstacle sensors 6 (see FIG. 4), and outputs to the drive unit 3 permission to open the movable fence 2 corresponding to the door of the stopped car according to the determined number of cars in the formation (see FIG. 1).

In the present embodiment, the control unit 4 pre-stores information about the number of train cars that will stop. A control part 4 discriminates the number of cars in the formation based on the existence or non-existence of vehicles detected by the obstacle sensor 6 for the movable fence 2 corresponding to the rearmost door of the formation in the possibility of each number of cars in the formation, and the obstacle sensor 6 for the movable fence 2 if there is a movable fence 2 behind the movable fence 2. - 特許庁

For example, it is assumed that there are cases where the number of train cars that stop at the station is 4 cars and 6 cars. Since the possibility of the number of cars of the train to stop is 4 cars and 6 cars, the information, that is, "4 cars" and "6 cars" is stored in the control unit 4 in advance. When the obstacle sensor 6 for the movable fence 2 corresponding to the rearmost door of the 4-car formation detects ``vehicles present'' and the obstacle sensor 6 for the movable fence 2 one behind the ``vehicles absent'' detects ``no vehicles,'' a control part 4 determines that the number of cars in the formation is 4 cars. Then, the control unit 4 outputs to the driving unit 3 permission to open the movable fence 2 corresponding to the door of the stopped four-car train.

When the obstacle sensor 6 for the movable fence 2 corresponding to the rearmost door of the 4-car formation detects ``vehicles present'' and the obstacle sensor 6 for the movable fence 2 one behind the ``vehicles present'' also detects ``vehicles present,'' the control part 4 does not determine that the number of cars in the formation is 4 cars. Then, an obstacle sensor 6 for the movable fence 2 corresponding to the rearmost door of the 6-car train detects "the presence of a vehicle", and if there is no movable fence 2 behind it, a control part 4 determines that the train consists of 6 cars. Then, the control unit 4 outputs to the driving unit 3 permission to open the movable fence 2 corresponding to the door of the stopped 6-car train. Note that the above 4 cars and 6 cars are examples and are not limited to these.

As a modification of the present embodiment, the control unit 4 may determine the number of cars in the formation based on the presence or absence of vehicles detected by all the obstacle sensors 6 .

For example, when the obstacle sensor 6 for the movable fence 2 corresponding to the door of the 1st to 4th cars from the front detects "vehicle present" and the obstacle sensor 6 for the movable fence 2 one behind the movable fence 2 detects "no vehicle", the control unit 4 determines that the train consists of four cars. Then, the control unit 4 outputs to the driving unit 3 permission to open the movable fence 2 corresponding to the door of the stopped four-car train.

Further, when the obstacle sensors 6 for all the movable fences 2 detect "the presence of vehicles", the control unit 4 determines that the number of cars in the train set is the maximum. Then, the control unit 4 outputs permission to open all the movable fences 2 to the drive unit 3 .

It should be noted that if some of the obstacle sensors 6 fail, the vehicle detection results from the plurality of obstacle sensors 6 will be in an impossible pattern, and the failure will be detected. The operation of the platform fence system 1 when a failure is detected is predetermined according to the pattern of detection results. For example, when the obstacle sensor 6 for one movable fence corresponding to the door of the intermediate car detects "no vehicle" and the other obstacle sensors 6 detect "vehicle present", the obstacle sensor 6 that detected "vehicle absent" is out of order and may be regarded as "vehicle present".

As described above, according to the platform fence system 1 according to the present embodiment, the obstruction sensor 6 provided to detect an object between the movable fence 2 and the platform edge E detects the presence or absence of a vehicle in front of the movable fence 2 on the track side. Therefore, it is possible to determine the number of cars in the formation without increasing the number of sensors, and to open the movable fence 2 corresponding to the door of the stopped vehicle.

A control part 4 pre-stores information on the possibility of the number of cars in a train set to stop, and if there is an obstacle sensor 6 for the movable fence 2 corresponding to the rearmost door of the train set in the possibility of each number of cars in the train set, and if there is a movable fence 2 one behind it, the number of cars in the train set is determined based on the presence or absence of the vehicle detected by the obstacle sensor 6 for the movable fence 2, so that the number of obstacle sensors 6 for detecting vehicles can be reduced, and the processing in the system is simplified.

As a modification, if the control unit 4 determines the number of cars in a train set based on the presence or absence of vehicles detected by all the obstacle sensors 6, it can easily handle various numbers of cars in a train set.

The present invention is not limited to the configurations of the above embodiments, and various modifications are possible without changing the gist of the invention. For example, the movable fence 2 may be of an elevating type in which a rope as a fence is raised and lowered.
