Description

  The present invention relates to a technique effective when applied to a platform door device installed on a platform of a railway station, and more particularly to a pillar-type movable platform fence configured to be movable by arranging a plurality of pillars in a horizontal direction.

2. Description of the Related Art In recent years, a platform on a railway line station platform (hereinafter simply referred to as a home) includes a door panel that can be opened and closed and a door bag that also serves as a safety fence for storing the door panel in order to ensure the safety of passengers. Is to be installed.
However, although the conventional platform door device is effective in ensuring the safety of passengers, there are problems that the manufacturing cost is high and the installation cost is high because the device is heavy and the home needs to be strengthened in many cases. In addition, since the door position of the home door device is generally fixed, problems such as difficulty in dealing with a plurality of door arrangements of vehicles of different vehicle types are obstructing the spread.

  An invention related to a lift-type platform door device that is light in weight and a simplified structure for these issues, and a platform door device that can change the opening position by making the doorcase itself movable as well as the door. It has been proposed (see Patent Documents 1 and 2).

  However, the elevating type platform door device described in Patent Document 1 may cause a problem that causes a safety problem such as contact with a passenger when the bar is lifted or baggage involved. In addition, the platform door device described in Patent Document 2 in which the door pocket is also movable cannot solve problems such as manufacturing cost and weight. In addition, both types require pillars fixed on the platform, and the door opening and closing control is a centralized control system that opens and closes all doors at the same time, making it difficult to respond flexibly in the event of a failure or abnormality. There is also. In addition, for maintenance of station equipment, there is a desire to be able to perform work of loading relatively large equipment and equipment from the work vehicle next to the platform onto the platform and loading equipment and removed equipment from the home to the work vehicle. However, the conventional platform door device cannot meet such a demand.

Patent Documents 3 and 4 describe the invention relating to a movable fence (movable home fence) capable of forming a relatively wide open space while having a relatively simple structure and being able to be configured at a low cost. There is something.
However, the home fence described in Patent Document 3 has a problem that safety is lowered because a partition tape is stretched between a movable column and a fixed column. . In addition, although the home fence described in Patent Document 4 can form a wide open space by stacking movable panels in a saddle manner during storage, the structure is complicated and increases in weight. However, there is a problem similar to the problem of the conventional platform door device that requires reinforcement work for the platform.

The present invention has been made paying attention to the problems as described above, and the purpose thereof is a movable that can form a relatively wide opening at an arbitrary position while ensuring the safety of passengers. It is to provide a type home rail.
Another object of the present invention is to provide a movable home fence that is easy to cope with a plurality of door arrangements of vehicles of different vehicle types, and that is lightweight and does not require construction to increase the strength of the home.

In order to achieve the above object, the present invention provides:
A guide device provided on a platform, comprising: a traveling device having a plurality of wheels provided at a lower portion of a columnar housing and a rotation driving means for the wheels; and a control device for controlling the rotation driving means. In a movable home fence in which a plurality of movable pillars configured to be movable along are arranged in a row at a predetermined interval,
A part of the movable pillars among the plurality of movable pillars move in a direction away from the boundary with a predetermined position as a boundary, thereby forming one or more openings centered on the boundary. Configured to be possible.

  According to the above means, it is possible to form an opening for getting on and off by moving the movable pillar while preventing the passenger from going over the home fence as a fence by aligning at regular intervals. it can. In addition, since the movable pillar moves on the platform, there is less risk of passengers coming in contact with it or involving baggage compared to the lift type, so an opening for getting on and off is formed while ensuring the safety of passengers. be able to. In addition, since the movable pillar can move in either the left or right direction, an opening can be formed at an arbitrary position, so that it is easy to cope with the arrangement of a plurality of doors of vehicles of different vehicle types, and a home having a door pocket. Since the weight can be reduced as compared with the door device, the work for increasing the strength of the platform is not required. Furthermore, even if some movable pillars break down, they can be easily replaced with normal ones and recovered in a short time.

Here, preferably, each of the plurality of movable pillars includes wireless communication means, and the control device of the movable pillar performs wireless communication with an adjacent movable pillar by the wireless communication means, and moves in its own direction. And a moving amount is calculated, and the rotational driving means is controlled to move based on the calculation result.
According to such a configuration, each movable pillar can be moved by a self-supporting control system and an opening of a predetermined size can be formed at an arbitrary position, so that a control device for controlling the whole is not required, and the system is down due to the system down. It is possible to avoid a situation in which the entire system becomes inoperable.

Preferably, each of the plurality of movable pillars includes receiving means capable of receiving a radio signal from a directional radio signal transmitting means provided corresponding to a door of a vehicle parked on the side of the platform. When the receiving means receives the directional radio signal, the movable pillar that has received the radio signal and the peripheral movable pillar move to form an opening corresponding to the range of the door of the vehicle.
As a result, when the train stops beside the platform, an opening for getting on and off can be formed according to the position of the door of the vehicle. It is possible to realize a platform fence applicable to a platform where a plurality of types of trains having different door positions and the number of vehicles stop without incurring an increase.

Furthermore, it is desirable to provide a centralized control device capable of transmitting / receiving data to / from at least one of the plurality of movable pillars, and the centralized control device is mounted on a vehicle that has moved to the side of the platform. When the information about the vehicle is received from the vehicle, the movable pillar to be moved, the moving direction and the moving amount are calculated based on the received information, and the data is transmitted to the corresponding movable pillar, and the movable pillar receiving the data moves. Thus, an opening corresponding to the range of the door of the vehicle is formed.
According to such a configuration, the central control device can receive information from the vehicle and move the movable pillar according to the type of vehicle (door position) to form an opening according to the vehicle, and is necessary for the self-sustained control method. Since it is not necessary to provide a highly functional control device for each movable pillar, the cost of each movable pillar can be reduced.

Preferably, it comprises a centralized control device capable of transmitting / receiving data to / from at least one of the plurality of movable pillars, and a photographing device for photographing a train that is arranged at a predetermined position on the platform,
The centralized control device determines the vehicle type and the number of vehicles based on the image signal from the imaging device, calculates the movable pillar to be moved, the moving direction and the moving amount, respectively, and transmits data to the corresponding movable pillar, The movable pillar that receives the data moves to form an opening corresponding to the range of the door of the vehicle.
According to such a configuration, the movable pillar can be moved in accordance with the type of vehicle (door position) without receiving information from the vehicle to form the opening corresponding to the vehicle, so that quick operation is possible. Thus, it is possible to avoid a situation in which, for example, the home fence does not operate due to an abnormality in wireless communication between the central control device and the vehicle.

Further, preferably, a centralized control device capable of transmitting / receiving data to / from at least one of the plurality of movable pillars, and a sensor for detecting the number of vehicles entering and stopping at a predetermined position of the platform. And comprising
The centralized control device determines the number of vehicles and the stop position based on the signal from the sensor, calculates the movable pillar to be moved, the moving direction and the moving amount, and transmits the data to the corresponding movable pillar. The movable pillar that receives the movement moves to form an opening corresponding to the range of the door of the vehicle.
This realizes a platform fence that can move the movable pillar and form an opening for getting on and off at an appropriate position according to the door position of the vehicle without any improvement or additional equipment on the vehicle side. Can do.

  Two sets of wheels 32a and 32b and axle 33 are provided in the front and rear, and are configured to travel with four wheels. Further, a brake device (not shown) including a brake shoe and a solenoid is provided on either of the wheels 32a and 32b. Further, a sensor or camera for grasping the distance from other movable pillars is provided on the upper portion of the casing 31 of the movable pillar 11. Further, a lamp, an alarm buzzer, or a speaker that is turned on or blinks when the movable pillar 11 is moved may be provided.

  Furthermore, rollers 39a and 39b that engage with the guide grooves 12a and 12b and slide inside are provided at the ends of the pair of rods 34a and 34b that protrude downward, and electromagnets 40Aa and 40Ab that constitute a locking device. It has been. On the other hand, the platform PH is embedded with electromagnets 40Baa and 40Bb which are opposed to the electromagnets 40Aa and 40Ab at a predetermined position to form a locking device together with the electromagnets 40Aaa and 40Ab, and a charging device (coil) 41 facing the charging unit 35B. ing. The lock device may include a lock pin and a solenoid that operates the lock pin. Note that a plurality of sets (for example, three sets) of rods 34a and 34b and tip rollers 39a and 39b may be provided. Further, the rollers 39a and 39b may not rotate.

  As shown in FIG. 3 (A), the movable home fence 10 of the present embodiment includes a plurality of movable pillars 11 having the above-described configuration along guide grooves (12a, 12b) on the home PH. As shown in FIG. 3 (B), when the train T stops, a plurality of movable pillars 11 move all at once and are arranged on the vehicle side. An opening that allows passengers to get on and off is formed at a portion corresponding to the door DR.

  Further, as shown in FIG. 3A, in the closed state where the movable pillars 11 are arranged at predetermined intervals, all the movable pillars correspond to the standby positions where the movable pillars 11 stop. A charging device 41 having the corresponding number of electromagnets 40B and charging coils is provided, and each movable pillar 11 has this standby position as a home position (charging spot), and is normally locked at this position. The built-in battery is configured to be charged. The non-contact charging of the battery using the coil has the same principle as the charging of the non-contact type IC card and is a well-known technique, and therefore detailed description is omitted.

  In the movable home fence 10 of the present embodiment, home positions (charging coils) are provided at predetermined intervals on the platform PH, and the number of movable pillars 11 corresponding to the number of each home position is provided, The charging device 41 and the movable pillar 11 are in one-to-one correspondence. The storage device of the control device 37 of the movable pillar 11 stores the identification code of the charging device 41 or the position information of the home position, and the movable pillar 11 and the charging device 41 are paired. The identification code of the charging device 41 may be an ID chip or a barcode, and a code reader for reading the code is preferably provided below the movable pillar 11.

  According to the movable platform fence 10 having the above-described configuration, the total weight can be greatly reduced compared to a platform door device having an open / close door and a door pocket, which is currently mainstream, and thus has been conventionally performed. Construction that increases the strength of the home is no longer necessary. In addition, even when a plurality of types of trains with different door positions stop, such as a three-door vehicle or a four-door vehicle, it can be opened and closed in accordance with the door position of the stopped train.

  Furthermore, the movable home fence 10 of this embodiment does not have a fixed column, and can move to a plurality of movable pillars to release an arbitrary range at an arbitrary position, thereby forming an opening for getting on and off. Also, for maintenance of station equipment, a relatively large piece of equipment or equipment is dropped from the work vehicle next to the platform onto the platform, or equipment or removed equipment is loaded from the platform onto the work vehicle, Easily find lost items. Furthermore, there is an advantage that correction of the stop position when the train stops past the stop position and modification for preventing the stop position from shifting are unnecessary.

Next, the control method of the movable pillar 11 in the movable home fence 10 of this embodiment is demonstrated. Here, two types of control methods will be described.
In the first control method, for example, a means for sending a directional radio signal toward the vehicle body side is provided on the train body, for example, at the lower part of the door, and a receiving means is provided on the surface of the movable pillar 11 on the track side. The movable pillar 11 is moved according to the opening range of the vehicle side door. As a directional radio signal, for example, a laser beam can be considered. The timing at which a directional radio signal is transmitted from the train side can be selected as the timing at which the train stops or the timing at which the crew operates the door opening button.

  FIG. 4A shows a state immediately after the wireless signal is transmitted. In the figure, six movable pillars 11 receive the radio signal L from the train T. These six and adjacent movable pillars 11 perform wireless communication with each other, exchange information regarding the position of the vehicle-side door DR, and determine the door opening range. Then, the control device 37 of the movable pillar 11 calculates its own moving direction and moving amount from its own position (home position) and door opening range, and the movable pillar determined to move is the locking device (electromagnet 40A). Is released.

  Specifically, the control device 37 grasps the number of movable pillars that are in the door opening range and the number of the pillar that is the end of the door opening range by exchanging information on the position of the door between the movable pillars 11. It is determined whether or not to move, and in the case of movement, the moving direction and the moving amount are calculated, and the locked state of the locking device (electromagnet 40A) is released. By using a pulse motor as the motor 36, the amount of movement can be controlled by the number of drive pulses.

  Thereafter, when the crew member operates the door opening button, the information or the command signal is wirelessly transmitted to each movable pillar 11, so that the control device 37 of the movable pillar 11 determined to move is a motor as a traveling device at that timing. 36 is driven and controlled. When the control device 37 detects that a radio signal (laser light) has been received, the control device 37 may determine that it is the door opening timing and start the movement. Further, the lamps of the movable pillars may be blinked during movement, and the blinking may be changed to lighting when the movement is completed.

  On the other hand, on the vehicle side, as shown in FIG. 4B, the vehicle-side door DR is opened by the crew operating the train-side door opening button. Thereafter, when the crew waits for passengers to finish getting on and off, and the crew operates the train side closing button, as shown in FIG. 4 (C), the transmission of the radio signal (laser light) from the vehicle side is stopped and the vehicle side The door DR is closed. Further, door closing information or a command signal is transmitted from the vehicle side to the movable pillar 11. When each movable pillar 11 receives the closing information or the command signal transmitted from the train side, it is determined that it is the closing timing, and the motor 36 as the traveling device is driven and controlled to return to the original position (home position). Then, the locking device (electromagnet 40A) is driven to enter the locked state. When the wireless signal (laser light) is not received, it is determined that it is the closing timing, and it may be returned to the home position.

FIG. 5 shows an example of a control procedure in the present embodiment. Among these, (A) is a control procedure on the vehicle side, and (B) is a control procedure by the control device 37 of the movable pillar 11.
As shown in FIG. 5A, the vehicle side first determines whether or not the vehicle has stopped (step S11), and outputs a directional radio signal toward the home side when the vehicle stops (step S12). . Subsequently, it is determined whether or not the door opening button has been operated (step S13). If it is determined that the door opening button has been operated, a door opening command signal (door opening information) is transmitted to the movable platform fence on the platform side ( Step S14), the vehicle side door is opened (Step S15).

Thereafter, it is determined whether or not the door closing button has been operated (step S16). When it is determined that the door closing button has been operated, the vehicle side door is closed (step S17). Next, a door closing command signal (door closing information) is transmitted to the movable platform fence (step S18), the output of the directivity wireless signal is stopped, and the process ends (step S19).
On the other hand, as shown in FIG. 5B, the movable pillar of the movable platform fence first reads a signal from a sensor that receives a directional radio signal (step S21). Then, it is determined whether or not the sensor is receiving a directional radio signal (step S22). If it is determined that the sensor is receiving, communication is performed with an adjacent pillar (step S23), and the movement direction and movement of itself are determined. The amount is calculated and the locking device is released (step S24).

  Thereafter, it is determined whether or not a door opening command (door opening information) from the vehicle side has been received (step S25). If it is determined that it has been received, the motor is driven and moved according to the result calculated in step S24. Then, the locking device is activated to enter a stopped state (step S26). Next, it is determined whether or not a door closing command (door closing information) from the vehicle side has been received (step S27). If it is determined that it has been received, the locking device is released, the motor is driven and moved to the home position (step). S28) The lock device is activated to enter a stopped state (step S29).

  According to the above control method, since the operation is controlled by the movable pillar itself, a central control device that controls the entire system is unnecessary, and it takes time to recover when the central control device fails and the system goes down. Nothing will happen. Moreover, since the signal which notifies the position and opening / closing timing of a door is transmitted from the vehicle side, it becomes easy to perform the interlocking control of the door opening / closing operation of a crew member and a home fence. Further, when any one of the movable pillars breaks down, it is only necessary to replace the failed pillar with a normal one. Therefore, there is an advantage that it is easy to deal with when a failure occurs.

FIG. 6A shows a configuration example of a control system for the movable pillar 11 for enabling the above control method. As shown in FIG. 6A, the control device 37 includes a sensor (or receiver) 21 for detecting a radio signal from the vehicle side, a battery 34, a radio communication module 38, a motor 36, an electromagnet (lock SOL) 40A. Is connected. When there is a notification lamp, the lamp 22 is connected to the control device 37 and is controlled.
The control device 37 includes a calculation control unit including a CPU (Central Processing Unit) and the like, and a storage unit such as a ROM (Read Only Memory) and a RAM (Random Access Memory), and a program stored in the ROM By cooperating with the CPU, each part is comprehensively controlled and necessary arithmetic processing is executed.

Next, another control method of the movable pillar 11 in the movable home fence 10 of the present embodiment will be described.
In the second control method, instead of providing a means for sending a radio signal (laser light) to the train car body side in the first control method, a camera capable of shooting a moving image on the track side surface of the movable pillar 11 ( An image pickup means), and the control device 37 performs image processing on the image pickup signal from the camera, thereby recognizing the arrival of the train and the position of the vehicle side door to determine the door opening range, and according to the detected door opening range. The movable pillar 11 is moved. Other than that, it is almost the same as the first control method. By exchanging information between the movable pillars, the movement of opening and closing linked as a whole can be realized.

FIG. 6B shows a configuration example of a control system of the movable pillar 11 for enabling the second control method. The difference from FIG. 6A is only that the sensor 21 in FIG.
The second control method has a demerit that the weight and cost of the movable pillar increase compared to the first control method because it is necessary to provide a camera on the movable pillar 11 side. There is an advantage that no renovation work is required to install the machine and sensor. Further, in the second control method, the opening operation by the crew member can be determined from the image, and the movement start timing of the movable pillar 11 can be obtained. Thereby, there exists an advantage that the addition of the apparatus which transmits the opening information on a train side and closing information to the platform fence side can be avoided. In addition, you may make it provide one camera for every several instead of providing in all the movable pillars.

Next, 2nd Embodiment of the movable home fence 10 of this embodiment is described.
In the first embodiment, each movable pillar is configured as a self-supporting control type. On the other hand, the second embodiment is configured as a centralized control system that controls all movable pillars with a single control device. is there. In the second embodiment, as shown in FIG. 7A, the wireless communication device 25 is mounted on the last cab of the train T, and the wireless module 38 (see FIG. A centralized control device 44 that communicates with the wireless communication device 25 using 3) and acquires necessary information is provided.

FIG. 7B shows a configuration example of the movable pillar 11 and a control system that controls the movable pillar 11 in the second embodiment. The configuration of each movable pillar is different from that of the first embodiment in that there is no sensor that receives a directional signal. The central control device 44 and the control device 37 of one of the movable pillars 11 are connected via a cable or the like so as to be able to transmit data. The transmission information from the central control device 44 to each movable pillar 11 may be transmitted from any movable pillar 11 to other pillars all at once, or may be configured to be transmitted in a relay manner by communication between pillars. Also good.
The central control device 44 may be provided with a wireless communication device that communicates with the train-side wireless communication device 25 and a wireless communication device that communicates with the wireless communication module 38 of each movable pillar 11.

  In the second embodiment, the centralized control device 44 controls the wireless module of the movable pillar 11 on the home side to perform bidirectional communication with the wireless communication device 25 on the train side, so that communication between the communication devices is performed. The distance is calculated and the stop position of the train is detected. Based on the detected stop position, the received vehicle type and the number of vehicles, the movable pillar to be moved, its moving direction and moving amount are calculated, and the instruction information is transmitted to each movable pillar 11. ing.

  In addition, as a technique regarding distance measurement by two-way communication, for example, there is a technique described in Japanese Patent Application Laid-Open No. 2014-020850. In this embodiment, a distance (train Stop position) can be calculated. In addition, a plurality of sets of transmitting means for transmitting a directional radio signal across the track and receiving means opposed to this are arranged at predetermined positions at the terminal end position of the home to detect the rear end of the train. The train stop position may be determined. Moreover, you may make it detect the rear end position of a train using a laser distance meter.

According to the second embodiment, a large-scale vehicle modification that provides a means for transmitting a directional radio signal (laser light) corresponding to the position to each door on the vehicle body side of the train becomes unnecessary. In addition, since the radio communication device 25 mounted on the train can be used to inform the central control device 44 on the home side that the train-side closing button has been operated and the vehicle type and number of vehicles of the train that has arrived. There is an advantage that the interlocking control of the opening and closing operation of the platform fence corresponding to the door on the train side can be easily performed.
In addition, instead of transmitting information on the vehicle type and the number of vehicles from the train, the train identification code is transmitted, and the central control device 44 is connected to the database, and the database is referred to based on the identification code received from the train. You may comprise so that the number of vehicles, ie, the door position which should be opened, may be judged.

Next, a modified example of the movable home fence 10 of the second embodiment will be described.
As shown in FIG. 8A, this modification is provided with a vehicle detection sensor 45 for detecting the number of vehicles entering the train and a stop position at the end position of the platform, and above the platform. A camera 46 for photographing the opening / closing operation of the train side door is provided.
FIG. 8B shows a configuration example of the control system in this modification. The signals of the vehicle detection sensor 45 and the camera 46 are configured to be input to the central control device 44.

The central control device 44 grasps the vehicle type, the number of vehicles, and the stop position based on the signal from the vehicle detection sensor 45 and the image signal of the camera 46, and determines the door position of the vehicle by referring to the table data in the storage device. Then, the movable pillar to be moved, the moving direction and the moving amount thereof are calculated, and the instruction information is transmitted to each movable pillar 11.
According to this modification, there is no need to mount a radio communication device on the train side, and no modification on the vehicle side or additional equipment is required. Further, since the processing on the movable pillar side constituting the home fence is simplified, it is easy to develop a program for the control device 37 of the movable pillar 11, and parts such as a CPU should be simple and inexpensive. Therefore, there is an advantage that the cost of the entire system can be reduced.

  Although the invention made by the present inventor has been specifically described based on the embodiment, the present invention is not limited to the embodiment. For example, when the central control device 44 receives a signal from a remote controller operated by a station clerk or the like without being based on the signals from the vehicle detection sensor 45 and the camera 46, the opening portion opens in an arbitrary range set or designated in advance. So as to form a movable pillar to be moved, a moving direction and a moving amount of the movable pillar, and a movement command is transmitted to the corresponding movable pillar. The plurality of movable pillars that have received the movement command may be configured to move in a designated direction by a designated use. As a result, for maintenance of the station equipment, it is possible to perform a work of unloading relatively large equipment and equipment from the work vehicle placed on the platform onto the platform, and loading equipment and removed equipment from the home to the work vehicle.

  In addition, in the movable home fence according to the first embodiment in which each movable pillar is configured as a self-supporting control type, for example, when a predetermined signal is sent from a remote controller, the movable pillars receiving the signal exchange information with each other. Then, the opening may be formed by calculating and moving the own moving direction and moving amount. At this time, the range of the pillar that has received the signal is determined to be an opening, and information is also sent to the adjacent pillar that has not received the signal to move to form an opening corresponding to the signal transmission range. You may comprise.

  Furthermore, in the above-described embodiment, a description has been given of a case where a rechargeable battery is used as a power supply device for each movable pillar. However, power can be supplied by a cable. Further, the lock device (electromagnets 40Aa, 40Ab) on the movable pillar side is omitted, and a lock pin or a lock arm and an electromagnet for operating the lock pin are provided only on the home side, and an engagement hole or engagement portion is provided on the movable pillar side. May be provided. Thereby, the weight of a movable pillar can be reduced.
