  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. It should be noted that the present invention is not limited to the embodiments described below, and modes to which the present invention can be applied are not limited to the following embodiments. In the description of the drawings, the same parts are denoted by the same reference numerals.

  FIG. 1 is a diagram illustrating an overall configuration example of an opening position variable type home fence system (hereinafter simply referred to as “home fence system”) 1 of the present embodiment. FIG. 2 is a diagram schematically illustrating a configuration example of one home fence 10. The home fence system 1 is arranged at the edge of the track 9 of the platform 9 where the train T arrives and departs and supervises the operation of the platform fence 10 with N platform fences 10 (N ≧ 2) that partition the platform 9 from the track side. And a control device 30 for controlling.

  Each of the home fences 10 has a structure in which the door pocket portion 11 supports two doors on the left and right or one door portion 13 on either the left or right side and is driven to open and close. The door pocket portion 11 is in the longitudinal direction of the platform 9. By moving along the (home longitudinal direction) and changing the position (opening position) of the opening between the adjacent door pockets 11 (the opening formed when the door 13 is opened), the position of the vehicle door It can handle trains with different positions and numbers.

  Specifically, the home fence 10 advances and retracts the door pocket portion 11, the door portion 13 that moves forward and backward from the door pocket portion 11, the door pocket drive portion 15 that moves the door pocket portion 11 along the home longitudinal direction, and the door portion 13. The door drive unit 17 to be moved and the door control unit 15 and the drive control unit 19 that drives the door drive unit 17 under the control of the control device 30 are provided.

  The door pocket part 11 is provided with an accommodation space in which the left and right door parts 13 can be accommodated in the thickness direction, and the door part 13 moves forward and backward (left and right direction) from the door pocket part 11 during the closing operation. The door 13 and the door tips of the adjacent home fence 10 come into contact with each other to close the opening (fully closed state). More specifically, in the closing operation, the left door 13 moves leftward and advances from the door pocket 11 toward the FIG. 1 and the like, and the right door 13 moves rightward and advances from the door pocket 11.

  In addition, the door pocket part 11 does not have a configuration in which an accommodation space is provided and the door part 13 is accommodated in the door pocket part 11, but the track side is exposed by omitting all or part of the side surface part on the track side. It may be configured to look like a partition from the platform side. Any configuration that functions as a door pocket for a passenger viewed from the platform side may be used.

  The door end of the door portion 13 is provided with a door end locking mechanism portion 21 that locks the door ends of the door portion 13 in a fully closed state (see FIG. 1). The door-end locking mechanism 21 is activated when the door 13 comes into contact with the door 13 of the adjacent door pocket 11 during the closing operation and the door 13 is fully closed, and the lock is released during the opening operation. It has become. The configuration of the door-end locking mechanism unit 21 can be realized using a known technique.

  On the other hand, at the time of the door opening operation, the door portion 13 moves in the opposite direction to that at the time of the door closing operation and is retracted and accommodated in the door pocket portion 11 to open the opening.

  Thus, the door pocket portion 11 that supports the door portion 13 so as to move forward and backward is erected on the carriage 115 that runs along the guide rail 92 in the under-floor space of the platform 9 via the pedestal 111. The guide rail 92 is laid along the home longitudinal direction below the track-side edge of the platform 9, and the carriage 115 driven by the door driving unit 15 travels on the guide rail 92, thereby Movement in the home longitudinal direction is guided. The guide rail 92 may be provided intermittently with a plurality of guide rails corresponding to each of the door pocket portions 11 according to the movement range (movable range of the carriage 115) along the home longitudinal direction.

  The door driving unit 15 is installed in the under-floor space of the platform 9. The door driving unit 15 is realized by, for example, a belt driving type driving mechanism, and includes a door driving motor (not shown) as a driving source, a driving pulley 151 connected to an output shaft thereof, and a moving direction of the door driving unit 11 ( In other words, the driven pulley 153 arranged at a certain distance from the driving pulley 151 along the home longitudinal direction), the timing belt 155 stretched between these pulleys 151, 153, and the pedestal 111 that supports the door pocket 11. Two belt fixing members 157 and 157 for fixing both ends of the timing belt 155 are provided.

  Here, a through hole 113 through which the timing belt 155 passes is formed in the pedestal 111, and the belt fixing members 157 and 157 are disposed in the vicinity of the left and right openings of the through hole 113, respectively. The timing belt 155 has one end fixed by one belt fixing member 157 and the other end fixed by the other belt fixing member 157, and an intermediate portion inserted through a through hole 113 provided in the base 111. Then, it is stretched over the drive pulley 151 and the driven pulley 153. Accordingly, when the door driving motor is driven to rotate the driving pulley 151, the timing belt 155 is rotated, and the door pocket 11 is moved in the longitudinal direction of the home. The distance between the axes of the pulleys 151 and 153 is set according to the movement range of the corresponding door pocket portion 11. The configuration of the door driving unit 15 is not limited to the belt driving method, and a driving mechanism such as a rack and pinion method or a ball screw method may be appropriately employed.

  Moreover, the door pocket drive part 15 is provided with the brake function which brakes rotation of the motor for a door pocket drive as a lock function which regulates the movement of the corresponding door pocket part 11. FIG. If the door driving motor is a servo motor, the brake function (lock function) is automatically activated by the rotation stop control to set the rotation speed to zero, and the stop state (stop position) is maintained. . In the present embodiment, the door driving motor is described as a servo motor. However, a brake component is provided separately from the motor and controlled to control the movement of the door 11 by realizing a lock function. Also good. In this case as well, when the rotation of the door driving motor is stopped, in principle, the lock function is activated.

  The door drive unit 17 is realized by, for example, a rack-and-pinion drive mechanism, and a door drive motor (not shown) that is a drive source, a pinion gear 171 connected to an output shaft thereof, and a side surface of the door unit 13 And a rack gear 173 disposed in parallel with the forward / backward movement direction (that is, the home longitudinal direction). The pinion gear 171 is fixedly disposed at an appropriate position of the door pocket portion 11. Therefore, when the door driving motor is driven, the pinion gear 171 rolls, the rack gear 173 meshing with the pinion gear 171 moves, and the door portion 13 moves forward and backward in the home longitudinal direction (door opening operation / Closing operation). Note that the configuration of the door drive unit 17 is not limited to the rack and pinion drive mechanism, and other drive mechanisms such as a belt drive system and a ball screw system may be appropriately employed. Moreover, the door drive part 17 incorporates the brake function which brakes rotation of the door drive motor as a lock function which controls the forward / backward movement of the corresponding door part 13. If this door drive motor is a servo motor, the brake function (lock function) is automatically activated by the rotation stop control with the rotation speed set to zero, similar to the door drive motor.

  The drive controller 19 drives the door driving motor in accordance with the door driving signal input from the opening position change controller 311 (see FIG. 6) of the control device 30, and the opening position change controller 311 and the door opening / closing controller. The door drive motor is driven in accordance with the door drive signal input from 317.

  The drive control unit 19 includes a self-diagnosis unit 191 that self-diagnose the occurrence of an abnormality in the corresponding door pocket drive unit 15. In the present embodiment, the self-diagnosis unit 191 performs a process for detecting a rotational operation failure of the door driving motor at any time, and notifies the controller 30 of an abnormality occurrence signal when a rotational operation failure is detected. It should be noted that the occurrence of another abnormality, such as a defective rotation operation of the timing belt 155, for example, may be detected as well as the rotational operation failure of the door driving motor, and when any of the abnormalities are detected and detected. It may be configured to notify the abnormality occurrence signal.

  The control device 30 performs an opening position change control process for changing the opening of the platform fence 10 (the opening position between the door pockets 11) according to the vehicle door position of the train T arriving at the station where the platform fence system 1 is installed, A door opening / closing control process for controlling the opening and closing operation of the door 13 when the passenger gets on and off the train T is performed. The control device 30 includes, for each train T train information that may arrive and depart from the installed station, the position of each door pocket 11 that matches the vehicle door position, and each door pocket that is the distance between the positions. Home fence drive information 353 (see FIG. 6) that defines the opening width between the doors 11, the door 13 to be opened and closed, the amount of advancement / retraction at the time of opening and closing, and the like is stored in advance. The formation information includes information such as the type of vehicle and the number of vehicles forming the train.

  Further, a detection signal from the stop position detection sensor 23 is input to the control device 30. The stop position detection sensor 23 detects the stop position of the train T that has arrived and stopped at the installation station, and outputs a detection signal related to the detected stop position to the control device 30.

  Here, in the process of the opening position change control process, the train information is exchanged between adjacent stations, and the arrangement position of the door pocket portion 11 corresponding to the next train arriving at the station is acquired. FIG. 3 is a diagram for explaining exchange of train information. As shown in FIG. 3, a station system 100 including a train information system 110 and a home fence system 1 is installed at each station, and the train information systems 110 at each station are connected to each other via a network N so that they can communicate with each other. Yes.

  The train information system 110 transmits and receives train information between adjacent stations. In this embodiment, it is assumed that train information includes knitting information for knitting the train. In addition, the train information can appropriately include information such as the vehicle door position of the train, the number of vehicle doors, the opening width of the vehicle door, the vehicle body length, and the train number of the train.

  For example, when the train T scheduled to arrive at the A station in FIG. 3 departs from the B station which is the immediately preceding station, the train information of the train T is changed from the station system 100 (100B) of the B station to the station system 100 (100A) of the A station. Is notified via the train information system 110. And in the station system 100A of A station, the control apparatus 30 reads and uses the corresponding home fence drive information 353 based on the train information notified from the station system 100 of B station, and performs opening position change control processing. . In the opening position change control process, the control device 30 controls the door pocket driving unit 15 and the door driving unit 17 via the drive control unit 19 for each home fence 10, and moves each door unit 13 forward and backward according to the opening width. This is a process of moving each door pocket portion 11 to the arrangement position while moving (advancing or retracting).

[principle]
Now, the opening position change control process is executed so as to be completed before the succeeding train T arrives after the preceding train T departs. FIG. 4 is a diagram illustrating an example of changing the opening position realized by the opening position change control process. In FIG. 4, the upper stage (1) shows the state of the platform fence 10 immediately before the preceding train T11 departs (immediately after the closing operation), and the lower stage (2) shows the time when the subsequent train T13 arrives (immediately before the opening operation). The state of the home fence 10 is shown. When the train T11 departs from the state (1) and train information of the train T13 that arrives next from the immediately preceding station is received, the opening position change control process is performed. If this opening position change control process is completed properly, as shown in (2), each door pocket part 11 moves to the arrangement position corresponding to the train T13 that arrives next, and matches the vehicle door position of the train T13. The opening position between the door pocket parts 11 is changed. FIG. 4 is a schematic drawing that focuses on the leading vehicle for the sake of simplicity, and is a schematic diagram in which the preceding train T11 is a three-door vehicle and the succeeding train T13 is a two-door vehicle, with different vehicle lengths. . Further, the preceding train T11 and the succeeding train T13 are illustrated as having different stop positions.

  However, if an abnormality occurs in the motor of the door pocket driving unit 15, the door pocket portion 11 does not move correctly to the next arrangement position, and there may be a problem that the opening position change control process is not properly performed. Therefore, in the opening position change control process of the present embodiment, the door driving unit 15 becomes abnormal by monitoring the presence / absence of notification of an abnormality occurrence signal from the self-diagnosis unit 191 (for example, rotation of the door driving motor). Recognize the home fence (abnormal home fence) 10 that has malfunctioned. And when the abnormal home fence 10 is recognized, an abnormal time control process is performed.

  FIG. 5 is a diagram for explaining an abnormality control process when an abnormality occurrence signal is notified from the self-diagnosis unit 191 of the home fence 10a in the state of FIG. 4A and the home fence 10a is recognized as the abnormal home fence 10a. It is.

  In the abnormal time control process, first, a first control for controlling the door driving unit 15 and the door driving unit 17 is performed. Since the opening position change control process is started after the door closing operation, the first control is performed in a state where all the door-end lock mechanisms 21 are operated.

  In the first control, first, in accordance with the platform fence drive information 353 of the train T13 that arrives next, a temporary arrangement position is calculated by shifting the arrangement position of each door pocket portion 11 to a relative position based on the position of the door pocket portion 11a. And the arrangement position of each door pocket part 11 is temporarily changed into a temporary arrangement position. Since the door pocket part 11a of the abnormal home fence 10a serves as a base point, the temporary arrangement position of the door pocket part 11a remains at the position at the time.

  And the movement amount (movement distance and direction of the movement) to the temporary arrangement position is specified for the door pocket portions 11 other than the door pocket portion 11a of the abnormal home fence 10a, and the door driving signal corresponding to the specified movement amount is supported. Output to the drive control unit 19. In addition, for each home fence 10 including the abnormal home fence 10a, the advance / retreat amount (the distance of advance / retreat movement and the direction of the advance / retreat movement) according to the opening width is specified, and the specified advance / retreat amount is specified. Is output to the corresponding drive control unit 19. In response to this, the drive control unit 19 releases the lock function (here, the brake function of the door driving motor) of the door driving unit 15 according to the door driving signal and drives the door driving motor, and according to the door driving signal. Drive the door drive motor. Thereby, while each door part 13 moves forward / backward according to the opening part width | variety, the door pocket parts 11 other than the door pocket part 11a move to a temporary arrangement position (FIG. 5 (1)-> FIG. 5 (2)). At this time, since the position of the door pocket portion 11 of the abnormal home fence 10a is the base point, the door function driving motor of the abnormal home fence 10a is in a movement restricted state in which the lock function (brake function) is not released. Of course, this is not necessary as long as the lock function (brake function) is broken and the lock (brake) is not functioning.

  If each home fence 10 is arrange | positioned in the temporary arrangement | positioning position because the door pocket parts 11 other than the door pocket part 11a move, 2nd control will be performed and the door pocket drive part 15 of each home fence 10 will be controlled. That is, in the second control, first, if the door pocket portion 11a is in the movement restricted state (if the lock function of the door bag driving motor is functioning), this is released. And the door part movement control signal which controls the advance / retreat movement of each door part 13 of each home fence 10 containing the abnormal home fence 10a is output to each drive control part 19, and the advance / retreat movement is prohibited. Receiving this, the drive control part 19 of each home fence 10 including the abnormal home fence 10a operates the brake function (lock function) of the door drive motor.

  Subsequently, a door driving signal corresponding to the amount of movement from the temporary arrangement position to the arrangement position is output to the drive control unit 19 of the home fence 10 other than the abnormal home fence 10a. In response to this, the drive controller 19 drives the door driving motor in accordance with the door driving signal. By the force by which each door pocket part 11 of the home fence 10 other than the abnormal home fence 10a moves to the arrangement position, the door pocket part 11a of the abnormal home fence 10a also moves to the arrangement position in conjunction with the movement (FIG. 5 (3)). In the second control, the home fences 10 other than the abnormal home fence 10a move by the same movement amount in the same direction. Therefore, each door pocket part 11 of the home fence 10 other than the abnormal home fence 10a can equally bear the load related to the movement of the abnormal home fence 10a that has become impossible to move by itself. That is, in the example of FIG. 5, the door pocket part 11 a is pushed by the door pocket part 11 on the left side of the door pocket part 11 a and is pulled by the door pocket part 11 on the right side to move to the correct arrangement position. The movement amount from the temporary arrangement position to the arrangement position matches the movement amount (movement distance and direction of the movement) of the door pocket portion 11a indicated by arrow A1 in FIG. This is because the temporary placement position is a relative position with the door pocket portion 11a of the abnormal home fence 10a as the base point. When the base point position is the correct position, all the home fences 10 are the correct placement positions.

  When there is no abnormality notification signal, the opening position change control process is performed by moving each door portion 11 directly to the arrangement position while moving each door portion 13 forward and backward according to the opening width. (Normal control process).

  In addition, in the opening position change control process of the present embodiment, when the train T13 arrives and stops after moving each door pocket portion 11 to the arrangement position, depending on the stop position of the train T13, if necessary, as appropriate. The door position drive unit 15 can be controlled to correct the placement position of each door portion 11 (stop position correction process). This is because the arrangement position of each door pocket portion 11 is determined based on a predetermined train stop position, but there may be a deviation between the specified train stop position and the stop position where the train T13 actually stopped. Because. Therefore, the difference between the specified train stop position and the stop position of the train T13 is obtained based on the detection signal from the stop position detection sensor 23. Correct the position of the position by shifting it by the amount of displacement. And the door pocket drive part 15 is controlled and each door pocket part 11 is moved to the arrangement position after correction | amendment. At this time, even when there is a door pocket drive unit 15a in which an abnormality has occurred, the corresponding door pocket portion 11 is moved to the corrected arrangement position in conjunction with the movement of the other door pocket portions 11 as in the second control. be able to.

  Moreover, the control apparatus 30 performs a door opening / closing control process after the train T13 stops. In the door opening / closing control process, the door driving unit 17 is controlled via the drive control unit 19, and the door 13 to be opened / closed is retracted according to the opening / closing amount during opening / closing operation, and according to the opening / closing amount during opening / closing operation. It is a process to advance. The door opening / closing control process may be performed in response to an input of an opening / closing instruction operation by a conductor or the like, or may be configured in conjunction with opening / closing of a vehicle door.

  As shown in FIG. 7, in the opening position change control process, first, the opening position change control unit 311 acquires train information of the next train that arrives from the train information system 110 (step S <b> 1). And based on the organization information contained in the acquired train information, the corresponding home fence drive information 353 is read from the memory | storage part 35 (step S3).

  Subsequently, the abnormal home fence recognition unit 313 determines the presence or absence of the home fence 10 in which the door driving unit 15 becomes abnormal. If there is no notification of the abnormality occurrence signal, there is no abnormal home fence 10a (step S5: NO), and the process proceeds to step S7 to perform the normal time control process of the opening position change control process.

  On the other hand, when the abnormality occurrence signal is notified from the drive control unit 19 of any home fence 10 (step S5: YES), the abnormality control unit 315 performs the abnormality control processing after step S11. Do. That is, as the first control, the abnormal time control unit 315 first determines the placement position of each door pocket portion 11 with reference to the door pocket portion 11a of the abnormal home rail 10a according to the home fence drive information 353 read in step S3. Temporarily change to the arrangement position (step S11). And while outputting the door drive signal according to the amount of advance / retreat based on opening width to the door drive part 17 of each home fence 10 containing the abnormal home fence 10a, the door drive signal according to the movement amount to a temporary arrangement position Is output to the drive control unit 19 of the home fence 10 other than the abnormal home fence 10a, and the door pockets 11 other than the door pockets 11a are moved to the temporary arrangement position while the doors 13 are moved forward and backward (step S13).

  Subsequently, as the second control, the abnormal time control unit 315 first cancels the movement restriction of the door pocket portion 11a when the door pocket portion 11a of the abnormal home fence 10a is in a movement restricted state (step S14: YES) (step S14). S15). Then, the abnormal time control unit 315 activates a lock function (in this embodiment, a brake function of the door driving motor) that restricts the forward / backward movement of each door 13 (step S17).

  And the abnormal time control part 315 outputs the door driving signal according to the movement amount from a temporary arrangement position to an arrangement position with respect to the drive control part 19 of the home fence 10 other than the abnormal home fence 10a, and other than the door pocket part 11a Each door pocket part 11 is moved to the corresponding arrangement position by driving the door pocket drive part of the door pocket part 11 (step S21). Thereafter, if necessary, the opening position change control unit 311 performs stop position correction processing (step S23).

  As described above, according to the present embodiment, even if there is a door pocket drive unit 15a in which an abnormality has occurred, the abnormal home fence 10a is caused by the movement of the door pocket unit 11 by the normal door pocket drive unit 15 and the forward / backward movement of the door unit 13. The door pocket portion 11a can be moved and moved to the arrangement position. Therefore, the door pocket part 11a of the abnormal platform fence 10a can be automatically moved to the correct arrangement position without requiring work by station staff or the like, and the influence on the train operation that the work time has can be suppressed. .

  In addition, in the said embodiment, although the rotation operation failure of the door driving motor was illustrated as abnormality of the door pocket drive part 15, for example, abnormality which the lock function which controls the movement of the door pocket part 11 does not function normally as another abnormality Can be considered. For example, suppose that the lock function of the door driving unit 15a of the home fence 10a becomes abnormal in FIG. In this case, since the movement of the door pocket part 11a cannot be restricted when moving to the temporary arrangement position, the door bag part 11 other than the door pocket part 11a is moved to the temporary arrangement position as follows after calculating the temporary arrangement position. Also good.

  That is, first, the door pocket 11 (11b) of the home fence 10 (10b) on the right side of the abnormal home fence 10a is moved to the temporary arrangement position. Specifically, the lock function of the door driving motor operating for the door driving unit 15 of the door portion 11b is released, the door driving motor is driven and moved to the temporary arrangement position, and the abnormal home fence The door part 13 on the right side of 10a and the door part 13 of the platform fence 10b are moved forward and backward according to the opening width. Next, the door pocket part 11 (11c, 11d) of the home fence 10 (10c, 10d) on the left side of the abnormal home fence 10a is moved to the temporary arrangement position. Specifically, the lock function of the door driving motor operating for the door driving unit 15 of the door pockets 11c and 11d is released to drive the door driving motor and move it to the temporary arrangement position. The door 13 on the left side of the home fence 10a and the doors 13 of the home fences 10c and 10d are moved forward and backward according to the opening width. As a result, the door pocket portions 11b, 11c, 11d other than the door pocket portion 11a move to the temporary arrangement position (FIG. 5 (1) → FIG. 5 (2)). After that, the second control is performed as in the above embodiment.

  Moreover, in the said embodiment, the movement to the temporary arrangement position of the door pocket part 11 other than the door pocket part 11a which is 1st control is moving each door part 13 forward and backward according to the amount of advance / retreat based on the opening width, The door pocket part 11 other than the door pocket part 11a is moved to the temporary arrangement position. On the other hand, the movement to the temporary arrangement position may be realized by driving only the door driving motor without driving the door driving motor. Specifically, by moving each door portion 13 forward and backward according to the opening width, the door pocket portions 11b, 11c and 11d other than the door pocket portion 11a are moved to the temporary arrangement position in conjunction with the forward and backward movement of the door portion 13. Move. In this case, prior to the forward / backward movement of the door part 13, the movement restriction state of the door pocket part 11 other than the door pocket part 11a is canceled (the door lock drive motor lock function of the home fences 10b, 10c, 10d other than the abnormal home fence 10a is released. To release.

  Moreover, in the said embodiment, it decided to identify the train which arrives next based on the train information exchanged between adjacent stations by the train information system 110 installed in each station. In contrast, each train is provided with a transmission device (for example, an IC tag) that stores and transmits train information related to the train, and reads the train information from the transmission device of the train that enters the station at each station. By providing the device, the reading information of the next arriving train may be read by the reading device and transmitted to the control device 30 of the station.

  Moreover, when the abnormal home fence recognition part 313 recognizes the abnormal home fence 10a, it can notify a station staff etc. by displaying the message on the display device 43 as appropriate. Then, for example, at night, after the operation ends, the door driving unit 15a can be repaired or replaced.
