Description

  The present invention relates to a platform fence for partitioning the platform from the track side and operating the vehicle safely.

  In recent years, railway stations have been actively installed with safety fences, so-called “home fences”, for partitioning the platform from the track side and operating the vehicle safely. The initial platform fence was simply an automatic door with a fixed location for opening and closing, so it could not accommodate the door positions of vehicles with different overall length sizes or vehicles with different numbers of doors. However, in recent years, self-propelled home fences that can move door pockets and doors and change the opening position and width can be flexibly adapted to various vehicle formations (for example, patents). Reference 1).

International Publication No. 2011/058940

  However, conventional self-propelled platform fences have many components installed on the platform, and many of them are constructed of heavy objects. Therefore, the occupied area on the platform increases, and a platform that allows passengers to pass through. The floor area of the room tended to be narrow. In addition, since it was necessary to lay grooves and rails for moving guides on the platform, there was a risk that passengers could crawl, and there was a possibility of failure of home fence operation due to foreign objects being caught.

  The present invention has been made in view of such circumstances, and while being able to flexibly cope with various vehicle formations, the area occupied by the components installed on the platform is reduced, and further, grooves are formed on the platform. The purpose is to provide a home fence that does not require a rail or rail.

  A first invention for solving the above problems is a movable platform fence for partitioning the platform from the track side by a partition structure from the track side and operating the vehicle safely, wherein the partition structure and the platform A movable body that has an opening on the side surface of the track along the longitudinal direction and moves in the longitudinal direction of the home in an installation space provided below the floor surface, and through the opening, the partition structure and the A plurality of moving units connected to a moving body, wherein the moving body is configured to be individually movable in the installation space with variable intervals, and by changing the stop position of the moving body, the partition structure It is a movable platform fence whose position changes and the entrance to the vehicle is provided in an openable / closable manner according to the vehicle door position.

  According to the first invention, by moving a plurality of moving units having a partition structure, the platform and the track side are partitioned (in a state where the home fence is closed), variously at various positions. It is possible to provide an opening for getting on and off of a large size. Therefore, it is possible to flexibly cope with vehicles having different positions and numbers of vehicle doors only by controlling the movement of the moving unit. Nevertheless, since the moving body that moves the moving unit is in the installation space below the floor, it is not necessary to install a large component with a built-in power mechanism on the platform, and the area occupied by the component to be installed on the platform is reduced. Can be small. Furthermore, the moving body and the partition structure are connected through an opening on the track side of the installation space. That is, it is not necessary to provide a groove or a rail for the movement guide of the movement unit.

  According to a second aspect of the present invention, the upper floor surface of the installation space is configured by a top plate, and the movable body is a top plate support portion that receives a load acting on the top plate (for example, the traveling roller 110, FIG. It is a movable home fence of 1st invention which has the top-plate support roller 111) of FIG.

  In the third invention, the moving body has a roller (for example, the traveling roller 110 in FIG. 5) for moving in the installation space, and the roller also serves as the top plate support portion. This is a movable home fence of the invention.

According to the second and third inventions, the surface on which the passenger gets on and off is configured to serve as a top plate which is an upper part for defining the installation space, so that the installation space can be used as a platform track. It can be provided as a side upper layer portion. This position is usually where a non-slip tile for a platform is buried, and if it is an existing platform, a space for providing an installation space can be secured relatively easily by peeling off the non-slip tile. That is, workability is excellent.
In the third invention, the roller for traveling the moving body in the installation space also serves as the top plate support portion, so that the moving body can be made thinner. This contributes to the reduction of the space width in the height direction required for installing the movable home fence of the present invention, and further contributes to the improvement of workability. Of course, the effect of reducing the number of parts and reducing the cost can also be expected.

  According to a fourth aspect of the present invention, there is a cord-like body (for example, the driving cord-like body 52 in FIGS. 6 and 7) spanned in the longitudinal direction of the home in the installation space, and a cord-like body drive for driving the cord-like body. And the movable body has a holding portion capable of holding / releasing the cord-like body, and moves in the installation space by holding the cord-like body by the holding portion, and the cord-like shape The movable home fence according to any one of the first to third inventions, wherein the plurality of moving units are configured to be movable by a driving force of a body driving unit.

  According to the fourth aspect of the present invention, each moving body moves in conjunction with the cord-like body by holding the cord-like body that is driven and moved along the longitudinal direction of the home, and releases the connection by releasing the holding. Then you can stop there. If a plurality of moving bodies simultaneously hold the cords having the same moving direction, the plurality of moving bodies can move simultaneously. Nevertheless, no matter how many moving bodies there are, at least one cord drive unit, that is, a power unit is sufficient. Therefore, it contributes to the reduction of the space required for the installation of the movable home fence and can be expected to reduce the manufacturing cost.

According to 5th invention, the 1st cord-like body and 2nd cord-like body from which a moving direction differs are provided, and the moving direction of a moving body can be changed freely by hold | maintaining any of them. Therefore, since the moving body can move in different directions at the same time, the time required for opening and closing the opening can be greatly shortened compared to the case of only the cord-like body moving in one direction.
In addition, the two cords having different moving directions are realized by one cord-like body by folding the cord-like body with a pulley and arranging the cord-like body along the longitudinal direction. Since both ends of the cord-like body are gathered at the other end in the installation space by folding the cord-like body, naturally, at least one cord-like body driving portion is sufficient. Therefore, the number of parts can be reduced.

  6th invention is a movable home fence of 4th or 5th invention in which the said mobile body has the penetration hole which penetrates the said cord-like body.

  According to the sixth invention, since the cord-like body penetrates the moving body, not only the rope-like body is a means for the moving body to move, but also the moving guide of the moving body and the original moving trajectory from It can also be used to prevent deviation.

  The configuration of the holding portion can be selected as appropriate. However, as a seventh invention, the moving contact body and the swinging contact body in which the holding portion is arranged to face each other with the cord-like body in between. And a drive mechanism for moving the moving contact body toward / separate the cord-like body, and the swinging contact body approaching / separating the cord-like body in conjunction with the approach / separation of the moving contact body. A movable home fence according to any one of the fourth to sixth inventions having a link can be configured.

  According to the seventh aspect, the movable contact body and the swing contact body of the holding portion can reliably hold and release the fixed long object or the driving rope-like body.

  The eighth invention further includes a fixed long object provided in the installation space along the longitudinal direction of the home, and the movable body can be locked / released to the fixed long object to fix the position. This is a movable home fence according to any one of the first to seventh aspects of the invention, which has an engaging portion.

  According to the eighth aspect, the position of the moving body can be fixed.

  According to a ninth aspect of the present invention, the mobile body has an optical wireless communication unit before and after the moving direction of the mobile body, and communication light from the optical wireless communication unit of each of the mobile bodies is in the installation space. The movable home fence according to any one of the first to eighth aspects, wherein the bus type network is formed in a straight line along the direction.

  According to the ninth aspect of the invention, since a plurality of moving bodies are arranged in series in the longitudinal direction of the home, data communication can be performed with each moving body with a simple configuration. It becomes possible to control movement. Since the communication method is wireless, it can be expected to reduce the number of parts compared to wired connection.

  A tenth aspect of the invention further includes a power supply line provided in the installation space along the longitudinal direction of the home, and the moving body includes a current collector that is in sliding contact with the power supply line. This is a movable home fence according to any of the inventions.

  FIG. 1 is a diagram showing a main configuration example of a movable platform fence to which the present invention is applied, and is a perspective external view obliquely looking down from above the platform. Moreover, FIG. 2 is the (1) top view which shows the installation state of a movable platform fence, (2) The front view seen from the platform side. Both figures show a state in which no opening for getting on and off is made, that is, a state in which the home fence is fully closed. In addition, in order to facilitate understanding, illustrations of power-related components, electric wires, communication cables, maintenance hatches, and the like are omitted.

  As shown in FIG. 1, the movable home fence 20 includes a thin installation space defining unit 40 having a small thickness in the height direction, and a column unit 60 fixed to the upper ends of the installation space defining unit 40 in a gate pillar shape. And a plurality of moving units 100 that can move between the support columns 60. Then, as shown in FIG. 2, the movable home fence 20 is configured so that the installation space defining part 40 is accommodated in the recess 5 provided at the side end of the platform 3 so that the moving unit 100 is along the longitudinal direction of the home. Installed. Although the total height of the movable home fence 20 can be set as appropriate, it is desirable that the height is equal to or higher than a person's waist height. The total length can also be set as appropriate.

  The installation space defining part 40 corresponds to the base part of the movable platform fence 20, and its depth (home-to-track direction dimension) and height are mainly non-slip tile homes installed at the end of the platform 3. -The size and thickness (length in the height direction) of the track direction are set to the same extent, and the dimensions fit within the space (recessed part 5) where the anti-slip tiles have been peeled off, so installation work on the existing platform Is considered to be easier. For example, the depth is about 400 mm to 500 mm and the height is about 50 mm. After the moving unit 100 is moved and the opening for getting on and off is formed, the upper surface of the installation space defining unit 40 functions as a floor surface continuous with the upper surface of the platform 3.

  The support | pillar part 60 is a hollow box. In a place that can be seen from the outside, there are a warning lamp 61 that is turned on when the movable home fence 20 is opened and closed, a speaker 62 for emitting a warning sound, an approach detection sensor 63, and a stay detection sensor 64. Is provided. Further, the main control board 70 and the power failure battery 80 are built in the internal space. In addition, a part of a drive mechanism section, which will be described later, power supply related components, and the like are appropriately incorporated.

  The approach detection sensor 63 is provided on each of the platform side and the track side across the row of partition structure bodies 102 of the mobile unit 100, and detects the approach of passengers to the partition structure body 102. For example, it is realized by a pair of a light projecting element and a light receiving element provided on the opposing surfaces of the two support columns 60, and the approach is detected by blocking the projected light.

  The occupancy detection sensor 64 is realized in the same manner as the approach detection sensor 63, and detects passengers left behind during the closing operation of the movable platform fence 20, luggages caught between vehicle doors, and the like.

The mobile unit 100 is a mobile partition for preventing passengers from falling from the home, and is arranged along the longitudinal direction of the home.
In this embodiment, since the partition structure 102 has a door plate shape, the arrangement positions of the partition structures 102 in the depth direction viewed from the platform side are different, and the partition structures 102 are adjacent to each other when adjacent moving units 100 approach each other. Are configured to be able to overlap in the depth direction. In addition, the total number of the mobile units 100 is not limited to seven as illustrated, and can be set as appropriate according to the total length of the movable home fence 20 and the assumed vehicle organization. Moreover, the form of the partition structure 102 is not limited to a plate-like body, and may be other forms.

The main control board 70 is a main controller that integrally controls the operation of the movable home fence 20. For example, a CPU 71, an IC memory 72, an input / output interface circuit 73, and an electronic circuit and an electric circuit (not shown) are mounted.
Then, the vehicle formation information and the opening / closing command of the vehicle arriving at the platform 3 are acquired from the external device 8 connected via the input / output interface circuit 73, and the movement unit 100 is controlled to move based on the acquired vehicle formation information. Thus, the opening can be formed at a position corresponding to the door of the vehicle to stop. Further, while the mobile unit 100 is moving, that is, during an opening / closing operation, the warning lamp 61 can be turned on and a warning sound can be emitted from the speaker 62. In addition, if the approach detection sensor 63 detects that the home fence is in a normal closed state, a voice guide that prompts the passengers to get close to the movable home fence 20 from the speaker 62 is released. It can be controlled to sound. Further, when there is a detection by the occupancy detection sensor 64, the closing operation control can be interrupted and the opening operation control can be executed.

  For example, FIGS. 3A and 3B are (1) a top view and (2) a front view showing a state in which an opening is provided substantially at one central position. FIGS. 4A and 4B are (1) a top view and (2) a front view showing a state in which openings are provided at two left and right positions. The position of the opening and the opening width are not limited to these patterns and can be set as appropriate. That is, if the position and width of the opening are defined in advance for each vehicle organization (in other words, if the movement target position of each moving unit 100 is defined), the position, number, and width of the vehicle doors vary. It is possible to flexibly cope with various vehicle formations.

  Further, attention should be paid to the upper surface of the installation space defining unit 40. The upper surface of the installation space defining unit 40 is a floor surface that passengers can step on when getting into the vehicle. On the upper surface of the installation space defining unit 40, grooves and rails for guiding the movement of the moving unit 100 are provided. Not provided. Therefore, there is no concern that passengers get on and off with grooves or rails as in conventional movable home fences, or that foreign objects get caught and interfere with the movement of the mobile unit 100.

  Then, how is the moving unit 100 moved without providing a groove or a rail for guiding the movement of the moving unit 100 on the upper surface of the installation space defining unit 40? In the present embodiment, the interior of the installation space defining unit 40 is caused to function as a rail of the movement guide, and the moving body is run inside. This configuration is made possible by connecting and supporting the moving body and the partition structure 102 so as to go around from the track side.

This will be specifically described.
FIG. 5 is an AA cross-sectional view (home to track cross-sectional view) of FIG. 2 and a partially enlarged view thereof.
The installation space defining unit 40 is covered with a floor plate 44 on the rail frame 42 opened on the upper side and the track side, thereby forming a long and thin hollow body in the longitudinal direction of the home having the opening 46 on the track side. Yes.

  The floor plate 44 is a top plate and an upper lid for the installation space defining unit 40, and the track side of the installation space defining unit 40 is an opening 46. The upper surface of the floor board 44 is a floor surface for passengers. In the present embodiment, the floor plate 44 is illustrated as a long single plate extending over the two support columns 60. However, the floor plate 44 may be appropriately divided into a plurality of pieces and separately connected together during construction. Good.

A lower rail groove 43 is formed in the upper surface of the rail frame 42 in the home longitudinal direction.
A plurality of moving bodies 104 are installed so as to be movable in the interior space of the installation space defining unit 40 so as to be guided by the lower rail grooves 43. That is, the installation space defining unit 40 defines the traveling space / installation space of the moving body 104 while functioning as the base part of the movable home fence 20.

  The track-side end portion of the moving body 104 protrudes from the opening 46 toward the track side, and is coupled and supported so as to bypass the track-side end portion of the floor plate 44 from the upper surface of the projecting portion toward the upper side of the floor plate 44. The part 106 extends. This connection support part 106 is extended in the state which floated slightly along the upper surface of the floor board 44, and the partition structure 102 is standingly arranged in the home side end.

  In other words, the mobile unit 100 bypasses the floor plate 44, which is stepped on by passengers, from the track side of the platform 3 to the home-to-track cross-sectional view “U-shaped” (or “U-shaped”), and the partition structure 102. As a result, the grooves and rails for the movement guide of the movement unit 100 need not be provided on the upper surface of the floor plate 44.

Next, a driving mechanism for moving the moving body 104 will be described.
FIG. 6 is a top view showing an internal configuration example of the installation space defining unit 40, and is a perspective view of the partition structure 102 and the connection support unit 106 of the moving unit 100 and the floor plate 44 of the installation space defining unit 40. It shows. The illustration of the lower rail groove 43 is also omitted.

  A cord drive unit 50 for transmitting power to the moving body 104 is installed using the internal space of the installation space defining unit 40 and a part of the internal space of the support column 60.

  The cord driving unit 50 includes a fixed long object 51, a driving cord 52, two winding drums 53 and 54, a pulley 55, an electric motor 56 capable of reversing the rotation direction, and an encoder 57. And have.

  The fixed long object 51 is installed along the home longitudinal direction between the two support columns 60, specifically, the center of the internal space of the installation space defining unit 40. The fixed long object 51 can be realized by a rod-like body such as a wire, a chain, a belt, or a rope, or a rod.

  The driving cable 52 is a transmission medium that transmits the driving force generated by the electric motor 56 to the moving body 104. The drive cord 52 can be realized by a cord, such as a wire, a chain, a belt, or a rope. Then, the driving cable-like body 52 is located on the left side (upper side in FIG. 6) from the first winding drum 53 disposed below the column part 60 on the right side (lower side in FIG. 6). ) And is returned to the lower side of the right column 60 and connected to the second winding drum 54.

  The first take-up drum 53 and the second take-up drum 54 are driven by an electric motor 56 controlled by the main control board 70 so as to rotate at the same speed in opposite directions. The rotation speed is constantly measured by the encoder 57 and input to the main control board 70. The main control board 70 determines the rotation direction of the electric motor 56 and controls the drive so that the feeding and winding of the drive cable 52 are not interrupted during the opening / closing operation from the measurement result.

  Therefore, if attention is paid to the movement of the drive cable 52, the first cable moves in one direction in the longitudinal direction of the home (left side of the front; upper side in FIG. 6) while there is only one drive cable 52. It functions as a second cord-like body that moves in the other direction. However, the direction depends on the rotation direction of the electric motor 56, in other words, whether the drive cable 52 is driven clockwise or counterclockwise toward FIG. The direction in which the driving cord 52 is driven and moved is referred to as “the cord moving direction”.

Next, a configuration example of the moving body 104 will be described.
FIG. 7 is an exploded perspective view illustrating a configuration example of the moving body 104 as viewed from obliquely above the track side.
The moving body 104 has a thin rectangular box shape and includes traveling rollers 110 at four corners. The diameter of the traveling roller 110 is larger than the thickness of the moving body 104, and the upper and lower portions are exposed from the moving body 104.

  The exposed lower portion of the running roller 110 is in contact with a lower rail groove 43 provided on the upper surface of the rail frame 42 along the longitudinal direction of the home, and the bottom of the moving body 104 is slightly from the upper surface of the rail frame 42. It will be in a floating state. On the other hand, the upper portion of the traveling roller 110 has a slight gap GP (see FIG. 5) between the lower surface of the floor plate 44 and is not in contact with the floor plate 44.

  Each of the side surfaces of the movable body 104 facing the longitudinal direction of the home is provided with three insertion holes 112, and either the fixed long object 51 or the driving cable-like body 52 is inserted into the insertion holes 112. Has been. The fixed long object 51 and the two driving cable-like bodies 52 pass through the moving body 104, thereby suppressing the displacement of the moving body 104 toward the opening 46 and preventing deviation from the lower rail groove 43. To do.

FIG. 8 is an overhead perspective view showing a structural example of the moving body 104.
The moving body 104 includes 1) a traveling roller 110, 2) a locking portion 130 corresponding to the fixed long object 51, and 3) a first holding portion 131 and a second holding portion corresponding to each of the two driving cords 52. A holding unit 132; 4) a position detection unit 140; 5) a power reception unit 150; 6) a moving body control board 170; and 7) an optical wireless communication unit 180.

The locking part 130, the first holding part 131, and the second holding part 132 have the same structure.
In particular,
1) a linear motion mechanism 134 that is driven and controlled by the moving body control board 170;
2) a moving contact body 135 that is approached / separated from the corresponding fixed long object 51 or the driving cable-like body 52 by the mechanism;
3) It is pivotally supported at a position facing the moving contact body 135 with the fixed long object 51 or the driving cable 52 sandwiched therebetween, and swings so as to be able to approach or separate from the fixed long object 51 or the driving cable 52. A swinging contact body 136 that
4) A link 137 that connects the moving contact body 135 and the swing contact body 136 is provided.
Note that it is preferable that the linear motion mechanism unit 134 is configured by concentrically connecting an electric motor and a ball screw because the length in the height direction can be reduced.

  The linear motion mechanism 134 is disposed so that the moving direction of the moving contact body 135 obliquely intersects the corresponding fixed long object 51 or the penetrating direction of the driving cable 52. Accordingly, the linear motion of the moving contact body 135 by the linear motion mechanism 134 is an approach / separation motion of the moving contact body 135 to the fixed long object 51 or the driving cable-shaped body 52. Specifically, FIG. 8 shows a state in which the moving contact body 135 of the locking part 130 is closest, and the moving contact bodies 135 of the first holding part 131 and the second holding part 132 are the most separated. Shows the state.

  When the linear motion mechanism 134 causes the moving contact body 135 to approach the corresponding fixed long object 51 or the driving cable-like body 52 (in FIG. 8, the moving contact body 135 moves from the bottom to the top of the figure. When the link 137 is moved, the link 137 pulls the swinging end of the swinging contact body 136 so as to approach the fixed long object 51 or the driving cable-shaped body 52.

  Eventually, when the moving contact body 135 comes closest to the fixed elongate object 51 or the driving cable body 52, the side surface of the moving contact body 135 hits the fixed elongate object 51 or the drive cable object 52 and swings or swings. The abutting body 136 swings so as to approach the fixed long object 51 or the driving cable-like body 52. Finally, the movable abutment body 135 and the swinging abutment body 136 clamp (clamp) the corresponding fixed long object 51 or the driving rope-like body 52, and the movable body 104 is integrally connected and fixed thereto. Will be. In the moving contact body 135 and the swing contact body 136, the fixed long object 51 or the drive cable 52 is appropriately provided on the contact surface that contacts the fixed long object 51 or the drive cable 52. It is effective to provide a fitting groove to enhance the clamping effect.

  In FIG. 8, a state where the central locking portion 130 clamps the fixed long object 51 is shown. Since the fixed long object 51 is fixed to the installation space defining part 40, the movable body 104 is fixed to the installation space defining part 40 by the locking part 130 clamping the fixed long object 51. Will be stopped.

  On the other hand, when the moving contact body 135 is moved in a direction away from the fixed long object 51 or the driving cable 52, the link 137 moves the swing end side of the swing contact body 136 to the fixed long object 51 or Push away from the drive cord 52. Finally, the fixed long object 51 or the driving cable 52 is released from clamping (clamping) by the moving contact body 135 and the swinging contact body 136, and the fixed long object 51 or the driving cable 52 is released. And an appropriate gap is formed between the moving contact body 135 and the swing contact body 136.

  In FIG. 8, both the 1st holding | maintenance part 131 and the 2nd holding | maintenance part 132 have shown the unclamped state which cancelled | released the clamp of the drive cable-shaped body 52. FIG. Even if the drive cord 52 is driven, power is not transmitted to the moving body 104 if both the first holding part 131 and the second holding part 132 are in an unclamped state. On the contrary, if either one of the two driving cords 52 penetrating therethrough is clamped and the clamp of the fixed long object 51 is released, the clamped driving cords 52 and the movable body 104 are connected, The moving body 104 travels in the installation space defining unit 40 by being pulled by the driving cable 52. The two driving cords 52 penetrating through are driven in opposite directions. Therefore, the moving direction of the moving body 104 is determined depending on which driving cord 52 is clamped.

The current position of the moving body 104 is detected by the position detection unit 140.
Specifically, the position detection unit 140 includes a position detection roller 141 that is supported so that the rolling surface is exposed from the lower surface of the installation space defining unit 40, and a rotary encoder 142 that is coupled to the rotation shaft of the roller. With. When the moving body 104 moves, the position detection roller 141 rolls on the lower inner surface (rail frame 42: see FIG. 5) of the installation space defining unit 40 and rotates according to the movement of the moving body 104. The rotary encoder 142 detects the rotation and outputs a detection signal to the moving body control board 170. In this embodiment, in the initialization at the time of power-on of the movable home fence 20, all the moving bodies 104 are brought close to one direction in the longitudinal direction of the home, and the position coordinates of each moving body 104 are set to the origin of movement control. Is initialized.

The power receiving unit 150 is a means for obtaining power used by the moving body 104.
In the present embodiment, two positive and negative power supply lines 47 are provided along the home longitudinal direction at the home side end of the back surface of the floor plate 44 of the installation space defining unit 40 (see FIG. 5). Of course, the power supply line 47 is connected to the power supply circuit to the movable home fence 20. The power receiving unit 150 is provided at a home-side end of the moving body 104 and a position directly below the power supply line 47, and includes two sliding contact current collectors 152 that are pressed upward. When the sliding contact collector 152 contacts the power supply line 47, power is supplied to the moving body 104.

  The moving body control board 170 controls the operation of the moving body 104 in an integrated manner. For example, a CPU, an IC memory, an input / output interface circuit, and the like are mounted. The mobile control board 170 executes a program stored in the IC memory, thereby 1) initializing the position coordinate system at startup and storing the current position, and 2) via the optical wireless communication unit 180. Data communication with the main control board 70, 3) Clamping to the locking part 130, the first holding part 131, and the second holding part 132 via the input / output interface circuit in order to realize the movement command received from the main control board 70 / Control to output a clamp release operation control signal. Of course, other controls can be performed as appropriate.

  The optical wireless communication unit 180 is realized by a known optical wireless communication device using a light projecting element, a light receiving element, a controller IC, and the like for communication light such as infrared rays. In the present embodiment, each moving body 104 is provided before and after the moving direction, and both are connected to the moving body control board 170. Moreover, the optical wireless communication part 180 is also provided in the lower part of the support | pillar part 60, and the optical wireless communication part in the support | pillar part 60 is connected to the main control board 70 (refer FIG. 2 (2)).

FIG. 9 is a diagram illustrating a configuration example of a communication network of the movable home fence 20.
The optical wireless communication unit 180 connected to the main control board 70 and the optical wireless communication unit 180 of each mobile unit 104 form a communication network capable of data communication with each other. Specifically, since each optical wireless communication unit 180 is arranged in a straight line along the longitudinal direction of the home, it forms a bus network by optical communication and communicates by a token bus system. For example, the movement command instructed from the main control board 70 to each mobile body 104 sets a value indicating the destination mobile body 104 in the destination ID 202 and sets a value indicating the main control board 70 in the transmission source ID 204. The cord moving direction 206 at that time and the target position information 208 for the moving body are transmitted. Of course, other information may be transmitted from the main control board 70 to the moving body 104. On the other hand, from the moving body 104 to the main control board 70, a value indicating the main control board 70 is set as the transmission destination, and a value indicating the own device is set as the transmission source ID 204, so Various status information and the like can be transmitted as appropriate.

  The cord movement direction 206 is a direction in which the driving cord 52 is driven, and is information indicating in which direction the cord is moved. It depends on the direction of rotation of the electric motor 56. For example, when the track-side drive cable 52 moves in the right-hand direction when viewed from the front and the home-side drive cable-shaped body 52 moves in the left-hand direction when viewed from the front, “1”, In the case of an inverse relationship, “0” or the like is set.

  The target position information 208 is the position coordinates of the destination that the moving body 104 can detect by the position detection unit 140, and the next stop vehicle formation information 530 that the movable home fence 20 acquired from the external device 8 (see FIG. 2). Is compared with the door open state setting data 510 stored in advance in the IC memory 72 (see FIG. 2) of the main control board 70.

  The door open state setting data 510 is prepared for each vehicle formation, and defines the position of each moving body 104 for realizing the position and number of entrances / exits corresponding to the vehicle formation. For example, as shown in FIG. 10, one door open state setting data 510 includes a vehicle organization ID 512 that is collated with the next stop vehicle organization information 530 and a target position information 208 for each moving body that defines target position information 208 for each moving body 104. Position data 514.

  The IC memory 72 (see FIG. 2) of the main control board 70 also stores the door closing state setting data 520 having the same data configuration as the door opening state setting data 510 (see FIG. 9). This defines the target position information 208 of each moving body 104 in the fully closed state in which the movable home fence 20 is closed.

  Each moving body 104 acquires a token having its own ID set in the destination ID 202, and the moving body control board 170 determines that the own body (own moving body) is based on the cord moving direction 206 and the target position information 208. By performing the movement control of 104), the opening / closing operation as the movable home fence 20 is realized.

Now, a specific operation of the movable home fence 20 will be described in detail.
FIG. 11 is a flowchart for explaining an example of a main control process executed by the main control board 70. The main control process is implemented by the CPU 71 executing a main control program 501 (see FIG. 10) stored in the IC memory 72. It is assumed that the movable home fence 20 has already been activated and the initialization of the position coordinate system of each moving body 104 has been completed.

  The main control board 70 receives the knitting information of the next arriving vehicle from the external device 8 (see FIG. 2), and stores it as the next stop vehicle knitting information 530 in the IC memory 72 (step S2). Then, the target position information 208 of each moving body 104 is determined with reference to the door open state setting data 510 that matches the current next stop vehicle formation information 530 (step S4), and the moving direction ( The cord moving direction 532 (FIG. 9) is determined (step S6).

When the vehicle stops on the platform 3, a predetermined “door opening command” is transmitted from the external device 8 toward the movable platform fence 20.
Next, when receiving the door opening command (step S10), the main control board 70 transmits a moving command for each moving body 104 (step S12). That is, the target position information 208 to which the moving body 104 should move is transmitted together with the cord moving direction 206. This is referred to as “communication A”.

  FIG. 12 is a flowchart for explaining an example of the moving body control process executed by the moving body control board 170. The processing is implemented by a CPU mounted on the mobile control board 170 executing a mobile control program (not shown) stored in an IC memory mounted on the mobile control board 170.

  When mobile unit 104 receives communication A addressed to itself (step S30), mobile unit 104 compares the current position in the fully closed state with target position information 208 included in communication A to determine the direction in which the own unit should move. (Step S32), in order to realize the movement in the determined direction, the drive-side cable 52 on the track side is clamped based on the cable-movement direction 206 included in the communication A, or the platform-side drive cable 52 is clamped. Whether to clamp the drive cord 52 is selected. That is, it is selected which of the first holding part 131 and the second holding part 132 is to be clamped (step S34).

  Next, the moving body control board 170 releases the clamp of the fixed long object 51 and drives the first holding part 131 or the second holding part 132 selected previously to drive the driving cable on either the track side or the home side. The body 52 is clamped (step S36). Then, a preparation completion signal (a predetermined status signal for notifying that preparation for movement has been completed) is transmitted to the main control board 70 (step S38). This is referred to as “communication B”.

  Returning to FIG. 11, when the main control board 70 receives the preparation completion signals from all the moving bodies 104 (step S50), the main control board 70 moves the drive cable 52 in the moving direction determined in step S6. Drive control is started (step S52).

  Each moving body 104 moves in the installation space formed by the installation space defining unit 40 by driving the electric motor 56. For example, as shown in FIG. 13, the track-side driving cable 52 moves to the left (upward in FIG. 13) when viewed from the front, and the platform-side driving cable 52 moves to the right (from FIG. 13). In the case where the electric motor 56 is driven so as to move in the downward direction (see FIG. 3) in the case where the electric motor 56 is driven in the center (see FIG. 3), it is closest to the right and left column portions 60 when viewed from the front. For the moving body 104, the target position information 208 is set to the current position (target position in a fully closed state without an opening: see FIG. 2). In other words, it does not move. Target position information 208 is set to the right side of the current position of the moving body 104 from the right column portion 60 to the second to third positions, and the home-side driving cord 52 is clamped and moved to the right. The second to fourth closest moving body 104 from the left column 60 has the target position information 208 set on the left side of the current position, and moves to the left by clamping the track-side drive cable 52. . As described above, the traveling roller 110 is grounded in the lower rail groove 43, but the upper portion has a slight gap GP with the lower surface of the floor plate 44. The floor plate 44 does not come into contact with the running resistance.

  Further, as shown in FIG. 1 and FIG. 7, the overall width (left and right lateral width) of the partition structure 102 is longer than that of the moving body 104, but the lower end portion of the partition structure 102 is the same length as the width of the moving body 104. It has the shape narrowed down locally. Moreover, when it sees between the adjacent mobile units 100, the position where the partition structure 102 is fixed to the connection support part 106 is shifted in the depth direction (home-track direction). Therefore, when the moving body 104 moves, the partition structure 102 starts to overlap in the depth direction, and an opening is started (see FIGS. 3A and 4B).

  Returning to FIG. 12, when the mobile unit control board 170 has reached the position indicated by the target position information 208 received in step S30 (step S60), the movable body control board 170 releases the clamp of the drive cable 52 and fixes it. The long object 51 is clamped (step S62), and a movement completion signal (a predetermined status signal for notifying that the movement has been completed and the target position has been reached) is transmitted to the main control board 70 (step S64). This is referred to as “communication C”.

  Returning to FIG. 11, when the main control board 70 that has driven the electric motor 56 receives a movement completion signal from all the moving bodies 104 (step S <b> 80), the main control board 70 stops the electric motor 56 and sets the drive cord 52. The movement is stopped (step S82). At this stage, the movable home fence 20 has completed the movement of the moving unit 100 and an opening has been formed (see FIGS. 3 and 4).

  A passenger gets on and off the floor plate 44 from the opening of the movable platform fence 20. There is a gap GP between the upper portion of the traveling roller 110 and the lower surface of the floor plate 44, and the floor plate 44 is in a slightly floating state. When the passenger gets on and off the floor board 44, the floor board 44 slightly sinks by the gap GP, but immediately comes into contact with the traveling roller 110 to support the tread force load. That is, the traveling roller 110 functions as a top plate support part. Of course, when there is no external force to be stepped on, the floor plate 44 is restored to its original position due to elasticity, and a gap GP is created again with the traveling roller 110.

When getting on and off is completed, a “door closing command” is transmitted from the external device 8 to the movable platform fence 20.
When the main control board 70 receives this door closing command (step S90), it sets the moving direction of the drive cable 52 (step S92), and refers to the door closing state setting data 520 (see FIG. 9). Then, the target position information 208 for making the fully closed state with the opening closed is transmitted to each mobile body 104 (step S94: communication A).

  Next, when the main control board 70 receives the preparation completion signals from all the moving bodies 104 (step S100), the main control board 70 starts driving the electric motor 56 so as to move the driving cable 52 in the moving direction determined in step S92. (Step S102). Then, when movement completion signals are received from all the moving bodies 104 (step S104), the electric motor 56 is stopped to stop the movement of the drive cord 52 (step S106). Thus, the movable home fence 20 has returned to the fully closed state in which the movement of the moving unit 100 is completed and there is no opening (see FIG. 2).

  Although not shown in these flowcharts, the main control board 70 detects that a passenger is detected on the track side of the partition structure 102 by the occupancy detection sensor 64 during execution of the platform fence door closing command. For example, once the control of the door closing operation is interrupted, a sound that prompts the speaker 62 to move to the home side of the partition structure 102 is emitted, and the door closing operation is performed if the detection by the residual detection sensor 64 is released. The control of is to be resumed.

  As mentioned above, according to this embodiment, it is not necessary to install the heavy-weight component for moving a door or a door pocket on a platform like the conventional self-propelled platform fence. Moreover, according to this embodiment, the occupation area on a platform can be made small. In addition, since it is not necessary to provide a groove or rail for guiding the movement of the home fence on the platform, there is no possibility of an operation failure caused by a passenger getting on or off or a foreign object being caught.

[Modification]
Note that the application form of the present invention is not limited to the example of the above-described embodiment, and components can be added, omitted, or changed as appropriate.

(Part 1)
For example, a door pinching detector 103 (see FIG. 1) can be provided as appropriate on the end face of the partition structure 102 of each moving unit 100 facing the home longitudinal direction. Then, if there is a detection by the door pinching detection unit 103, the movement control of the driving cable 52 is immediately stopped in consideration of the possibility that the passenger's body or belongings are caught in the partition component 102. Thus, control is performed so that the electric motor 56 is temporarily reversed slightly and the pinch is removed. After that, it is preferable to perform control so that the original movement control is resumed. The door pinching detection unit 103 can be realized by appropriately adopting a known door pinching detection structure employed in a known contact detection sensor, an elevator door, or the like.

(Part 2)
Moreover, in the said embodiment, although the power supply line 47 was provided in the lower surface of the floor board 44, the home side standing surface side (back wall part of installation space) of the rail frame 42 and the upper surface side (installation space of installation space) of the rail frame 42 are provided. It may be provided on the bottom surface.

(Part 3)
Moreover, in the said embodiment, although the function as a top-plate support part which supports the load to the floor board 44 was combined with the traveling roller 110, the structure which provides a top-plate support part separately is also possible. For example, as shown in FIG. 14, the traveling roller 110 has a diameter smaller than the thickness of the moving body 104 and is exposed only from the lower portion of the moving body 104 and rolls on the rail frame 42. In addition to the traveling roller 110, a top plate support roller 111 that abuts on the lower surface of the floor plate 44 and freely rotates may be provided. In this case, the gap GP can be eliminated.

(Part 4)
Moreover, as shown in FIG. 15, the structure which provides the mobile body 104 under the side edge part of the platform 3 is also possible. In this case, the floor plate 44 functions as an upper rail frame and a member for fixing the installation space defining unit 40 to the lower surface of the platform 3 and is not stepped on by passengers.

(Part 5)
Further, in the above embodiment, the movement of the moving body 104 is realized by connecting to the driving cable-like body 52. However, each of the moving bodies 104 is equipped with an electric motor capable of reversing the rotation direction to drive the traveling roller 110. A configuration in which each of the moving bodies 104 is allowed to self-run is also possible.

(Part 6)
Moreover, the structure of the latching | locking part 130, the 1st holding | maintenance part 131, and the 2nd holding | maintenance part 132 is not restricted to the said embodiment, and can be changed. For example, a configuration using a toggle mechanism as shown in FIG. 16 is also possible. Specifically, the fixed contact body 191 is disposed on one side with the fixed long object 51 and the drive cable-shaped body 52 interposed therebetween, and the swing contact body 192 is disposed on the other side. The swing end of the swing contact body 192 is connected to a toggle link 193 that is linearly moved by the linear motion mechanism 134. As shown in FIG. 16 (1), when the toggle link 193 is pulled near by the linear motion mechanism 134, the swing contact body 192 is separated from the fixed long object 51 and the driving cable body 52 and the connection is released. As shown in FIG. 16 (2), when the toggle link 193 is pushed out by the linear motion mechanism 134, the swinging contact body 192 approaches the fixed long object 51 and the driving cable-like body 52, and is finally fixed at the contact surface. The long object 51 and the driving cord 52 are pressed against the fixed contact body 191 to be connected.
