Description

  The present invention relates to a movable home fence and a movable home fence row.

  The movable platform fence is a kind of automatic door device that is installed on the platform of the railway station and opens and closes the entrance / exit passage. The movable platform fence opens the entrance / exit passage when the train arrives on the track in contact with the platform, and enables passengers to enter and exit the train. Prevent falls.

  The movable platform fence includes a fixed portion fixed to the platform, and an opening / closing member that is supported by the fixed portion so as to be movable and opens and closes the entrance / exit passage. A train is formed by connecting a plurality of vehicles, and each vehicle is provided with a plurality of passenger doors. Therefore, on the platform, movable home fences corresponding to the total number of passenger doors included in the train are arranged to constitute a movable home fence row.

  Now, depending on the line section, there are cases where trains with different numbers of vehicles are mixed and operated. That is, there are cases where trains with different total number of passenger doors are mixed and operated. In addition, the stop position of the train may be changed. For this reason, the total number of entrance / exit doors provided on the train that has arrived on the track in contact with the platform may not match the number of entrance / exit passages that are opened and closed by the movable platform fence row installed on the platform. In such a case, in some movable home fences, the vehicle may not exist on the facing track. When there is no vehicle on the facing track, the movable home fence needs to be kept closed for passenger safety. For this reason, in a line section operated with a mixture of trains with different numbers of vehicles, it is necessary to change the movable platform fence that is opened and closed for each train that arrives on a track that contacts the platform. A plurality of inventions relating to a device for changing a movable home fence to be opened and closed have already been filed for a patent.

  In Patent Document 1, in order to change the movable platform fence to be opened and closed for each train arriving on a track in contact with the platform, various types of trains having different numbers, positions, and width dimensions of entrance / exit passages are provided on the platform door device. It is disclosed that an individual control device in which format information is registered in advance is provided. And in invention of patent document 1, when transmitting an "open" instruction | command from the train side to a platform door apparatus, the format information of a train is also transmitted to an individual control apparatus, and according to the transmitted format information The individual control device opens and closes the platform door.

  Japanese Patent Application Laid-Open No. 2004-228688 discloses a platform that includes a first sensor that detects the rear part of the vehicle body of the m-th vehicle, a second sensor that detects the vehicle body center part of the m + 1-th vehicle, and a vehicle body center part of the last vehicle.

  In the invention described in Patent Document 1, it is necessary to register the train format information in advance, which takes time. Moreover, it is necessary to install a system for transmitting train format information on the train side, and the system configuration becomes large. Therefore, the invention described in Patent Document 1 has a problem that the equipment cost becomes high.

  The invention described in Patent Document 2 is based on the premise that the leading vehicle always stops at the same position. Therefore, the invention described in Patent Document 2 has a problem that it cannot be applied when the stop position of the leading vehicle is changed. Moreover, since it is necessary to arrange | position a dedicated sensor in a platform, there exists a problem that an installation cost becomes high.

  The present invention has been made under such a background, and even when the number of vehicles constituting the train and the stop position of the leading vehicle are changed, the vehicle is stopped on the track facing the movable platform fence. Only to provide a movable platform fence that is allowed to open. Moreover, the movable home fence row | line | column comprised by arranging this movable home fence is provided.

  A movable platform fence according to the present invention includes a fixed portion fixed to a platform, and an opening / closing member that is movably supported by the fixed portion and opens and closes the entrance / exit passage. A sensor for detecting presence or absence is provided.

  According to the present invention, since the movable home fence is provided with a sensor for detecting the presence or absence of the vehicle, in each of the movable home fences constituting the movable home fence row, is the vehicle arriving on the track facing the movable home fence? It can be determined whether or not. Therefore, it becomes unnecessary to provide a dedicated sensor for detecting the presence or absence of the vehicle in the platform separately from the movable platform fence.

  According to the present invention, in the control device that controls the movable home fence, referring to the detection result of the sensor, when the sensor does not detect the vehicle, the opening of the boarding / alighting passage can be stopped. Therefore, when the number of train vehicles and the stop position of the leading vehicle are changed, it is not necessary to individually transmit information on the number of vehicles and the stop position from the host control device to the control device of the movable home fence.

  According to the present invention, it is possible to use an area sensor provided on a movable home fence as a sensor for detecting the presence or absence of a vehicle in order to detect entry and overpass of foreign objects and passengers. Therefore, a movable home fence that can detect the presence or absence of a vehicle without increasing the number of sensors is realized.

  Hereinafter, a movable home fence and a movable home fence row according to an embodiment of the present invention will be described in detail with reference to the drawings. In the drawings, the same or equivalent parts are denoted by the same reference numerals.

  FIG. 1 is a diagram showing a state in which a plurality of movable home rails 1 according to an embodiment of the present invention are arranged on a platform 2 of a railway station to form a movable home rail row 3. It is the front view which looked at from the platform 2. FIG.

  In the following, an orthogonal coordinate system as shown in FIG. 1 is set. That is, the X coordinate is set in the length direction of the platform 2, the Y coordinate is set in the height direction, and the Z coordinate is set in the direction orthogonal to the X coordinate and the Y coordinate, that is, in the width direction of the platform 2. In FIG. 1, the direction from left to right is the positive direction of the X coordinate, the direction from the bottom to the top is the positive direction of the Y coordinate, and the direction from the trajectory toward the platform 2 is the positive direction of the Z coordinate.

  As shown in FIG. 1, the movable platform fence 1 includes a fixed portion 4 fixed to the floor surface of the platform 2, and an opening / closing member that is attached to the fixed portion 4 so as to be movable in the X-axis direction and opens and closes the entrance / exit passage 5. The door bodies 6a and 6b functioning as Further, a plurality of movable home fences 1 are arranged in series in the X-axis direction, and constitute a movable home fence row 3.

  In addition, the fixing | fixed part 4 is comprised by the box shape as a whole, and is generally called a door pocket. The door bodies 6a and 6b are sliding doors that are attached to the door pocket so as to freely advance and retract. FIG. 1 shows a state in which the door bodies 6 a and 6 b close the entrance / exit passage 5. At this time, the door bodies 6 a and 6 b are drawn out of the fixed portion 4. When the entrance / exit passage 5 is opened, the door bodies 6 a and 6 b are drawn into the fixed portion 4. Further, the movable home fences 1 are arranged with the boarding / alighting passages 5 interposed therebetween, and in the state shown in FIG. 1, that is, in the state where the boarding / alighting passages 5 are closed, the door bodies of two adjacent movable home fences 1. The door tips 6a and 6b abut against each other.

  2A is a plan view of the movable home fences 1a and 1b, and FIG. 2B is a rear view of the movable home fences 1a and 1b as viewed from the track side. 2A and 2B show a state in which the door bodies 6a and 6b are pulled out from the fixed portion 4. FIG. That is, FIG. 2 (A) and FIG. 2 (B) show the outer shape of the movable home fences 1a and 1b in the closed state. The door bodies 6a and 6b are movably supported by the fixed portion 4 via guide rails (not shown), and are driven by an electric motor (not shown) to move in the X-axis direction.

  A laser sensor 7 is fixed to the wall surface of the fixed portion 4 on the track side. The laser sensor 7 is a kind of distance meter that projects and reflects laser light on a target and measures the distance to the target based on the phase difference between the projected light and the reflected light. Further, the laser sensor 7 includes a turning and raising / lowering mechanism (not shown). Therefore, as shown in FIG. 2A, the laser sensor 7 can turn around the turning axis and scan the laser light within the horizontal scanning plane Hp. Further, as shown in FIG. 2B, the laser sensor 7 can turn around the elevation axis to scan the laser light within the vertical scanning plane Vp. Therefore, the laser sensor 7 can detect the azimuth and distance of the target in the detection range. That is, the laser sensor 7 functions as a three-dimensional distance image sensor that detects the three-dimensional coordinates of the target. Further, the laser sensor 7 functions as an area sensor that detects the presence of the target in the range shown in FIGS. 2 (A) and 2 (B).

  As shown in FIG. 2A, the movable home fences 1 a and 1 b are provided with a control device 8. The door bodies 6a and 6b and the laser sensor 7 are controlled by the control device 8. The control device 8 is controlled by a host control device (not shown), that is, a control device that controls the entire movable home fence row 3. The control device 8 includes a computer (not shown), and a program to be described later is installed in the computer. The laser sensor 7 included in the movable home fence 1a is connected to both the control device 8 of the movable home fence 1a and the control device 8 of the movable home fence 1b. As described above, the laser sensor 7 included in the movable home fence 1a is shared between the movable home fences 1a and 1b. Similarly, the laser sensor 7 provided in the movable home fence 1b is shared between the movable home fence 1b and another movable home fence 1 (not shown) adjacent to the movable home fence 1b.

  FIG. 3 is a diagram showing the classification of the detection range of the laser sensor 7 referred to in the program installed in the control device 8. As shown in FIG. 3, the area between the outer edge 2a of the floor surface of the platform 2 and the door bodies 6a and 6b is restricted because passengers are allowed to enter only when the movable platform fence 1 is in the open state. It is divided into areas LA. The area between the outer edge 2a of the floor surface of the platform 2 and the fixed portion 4 is divided into a prohibited area PA because passengers are always prohibited from entering. The region on the track side from the outer edge 2a of the floor surface of the platform 2 is divided into the vehicle area CA because it is a region in which no object other than the vehicle exists in principle. As described above, since the laser sensor 7 provided in the movable home fence 1a is shared between the movable home fences 1a and 1b, the detection data acquired by the laser sensor 7 provided in the movable home fence 1a is: It is referred to by both the program executed by the control device 8 of the movable home fence 1a and the program executed by the control device 8 of the movable home fence 1b.

  Now, when the movable home fence 1 is in the closed state, if the laser sensor 7 detects the presence of any object in the restricted area LA and the prohibited area PA, there is a possibility that the passenger is going over the movable home fence 1. In that case, it is necessary to issue a warning to the passenger and to notify the attendant of the occurrence of the abnormality. Therefore, an alarm program as shown in FIG. 4 is installed in the control device 8. The alarm program is activated when the laser sensor 7 detects the presence of any object in the restricted area LA and the prohibited area PA. When the alarm program is started, alarm processing as shown below is executed. That is, first, an alarm device (not shown) is activated to prompt a passenger who has entered the restricted area LA or the prohibited area PA to exit (step 11), and an alarm device (not shown) is activated to cause an abnormality to occur to an attendant. Report (step 12) and finish the process. The alarm program is also activated when the laser sensor 7 detects the presence of any object in the prohibited area PA when the movable home fence 1 is in the open state. Also, the operation of the alarm device is manually stopped after the staff member who has received the notification confirms safety.

  When the movable platform fence 1 opens the entrance / exit passage 5, when an upper control device (not shown) orders the control device 8 to close the entrance / exit passage 5, the laser sensor 7 is present in the restricted area LA. , The passenger may be staying in the restricted area LA for some reason. In this case, it is necessary to wait for the passenger passage 5 to close until the passenger leaves the restricted area LA. Moreover, when a passenger does not leave the restricted area LA, a staff member needs to check the situation and take necessary measures. For this purpose, the control device 8 is installed with a door closing stop program as shown in FIG. The door closing stop program is activated when the laser sensor 7 detects the presence of any object in the restricted area LA when the host controller instructs the controller 8 to close the entrance / exit passage 5. When the door closing program is started, the door closing process as shown below is executed. That is, first, the door closing operation is stopped (step 21). Then, it waits for 3 seconds (step 22). Thereafter, if the laser sensor 7 does not detect the presence of an object (step 23; NO), the door closing operation is resumed (step 24), and the process is terminated. If the laser sensor 7 has detected the presence of an object even after 3 seconds have elapsed (step 23; YES), the control device 8 operates a notifying device (not shown) to notify the staff of the occurrence of an abnormality (step) 25) Then, return to Step 22.

  A door opening permission program as shown in FIG. 6 is also installed in the control device 8. The door opening permission program is activated when a train arrives on a track in contact with the platform 2 and a higher-level control device (not shown) instructs the control device 8 to open the getting-on / off passage 5. When the door opening permission program is started, door opening permission processing as shown below is executed. That is, first, search for an object in the vehicle area CA by the laser sensor 7 is started (step 31). In principle, no object other than the vehicle can exist in the vehicle area CA. Therefore, if the laser sensor 7 detects the presence of the object in the vehicle area CA (step 32; YES), the vehicle is on the track facing the doors 6a and 6b. Since it can be determined that the vehicle is stopped, the door opening is permitted (step 33), and the process is terminated. If the laser sensor 7 does not detect the presence of an object in the vehicle area CA (step 32; NO), the process ends without permitting the opening of the door. Thus, since the door opening permission program is installed in the control device 8 and the upper control device instructs the control device 8 to open the door, the door opening permission program is executed. When the laser sensor 7 detects the presence of the vehicle, the laser sensor 7 functions as a door opening permission means for permitting the opening of the passenger passage 5.

  Here, it is assumed that the platform 2 is capable of receiving and arriving a train 10 formed by connecting five vehicles 9 each having three entrance doors on one side. That is, the platform 2 which can make the train 10 provided with a total of 15 entrance / exit doors on one side arrive and depart is assumed. In this case, as shown in FIG. 7 (A), the platform 2 is required to have 16 movable home fences 1 arranged and a movable home fence row 3 having 15 entrances and exit passages 5. is there. When the train 10 arrives on the track in contact with the platform 2, the presence of the vehicle 9 is detected in all the getting-on / off passages 5, so that all the getting-on / off passages 5 are opened as shown in FIG. 7B.

  Next, it is assumed that a three-car train 11 arrives and departs on this platform 2. When the leading vehicle 9 a of the train 11 stops at the left end of the platform 2, nine entrance passages 5 on the left side of the platform 2 are opened as shown in FIG. On the other hand, since the presence of the vehicle 9 is not detected in the six entrance / exit passages 5 on the right side of the platform 2, the entrance / exit passages 5 are not opened.

  When the rear vehicle 9c of the train 11 stops at the right end of the platform 2, as shown in FIG. 7 (D), the nine entrance passages 5 on the right side of the platform 2 are opened. On the other hand, since the presence of the vehicle 9 is not detected in the six entrance / exit passages 5 on the left side of the platform 2, these entrance / exit passages 5 are not opened.

  When the train 11 stops at the center of the platform 2, as shown in FIG. 7 (E), nine entrance / exit passages 5 at the center of the platform 2 are opened. On the other hand, since the presence of the vehicle 9 is not detected in the left and right three places of the platform 2 and the right three places of the getting-on / off passages 5, these getting-on / off passages 5 are not opened.

  As described above, according to the movable platform fence row 3 according to the embodiment of the present invention, even if the number of trains 10 and 11 or the stop position of the leading vehicle is changed, the movable vehicle 9 exists on the facing track. Only the home fence 1 can be opened, and the movable home fence 1 in which the vehicle 9 does not exist on the facing track can be closed.

(Modification)
The sensor provided in the movable home fence 1 is not limited to the laser sensor 7. As shown in FIG. 8, a column 12 may be erected on the fixed portion 4 of the movable home fence 1, and the CCD camera 13 may be fixed to the upper end of the column 12. The CCD camera 13 is attached downward so that the movable home fence 1 and the platform 2 can be accommodated in the field of view.

  The CCD camera 13 includes an image processing device (not shown) and can extract the contour of an object from the captured image. The data related to the contour of the object extracted by the CCD camera 13 is determined by collating with the template stored in the control device 8. As a result, it is determined whether the object imaged by the CCD camera 13 is a vehicle, a passenger, or another foreign object. Thus, according to the CCD camera 13, it is possible to detect vehicles, passengers, and other foreign objects in the field of view of the CCD camera 13. That is, the CCD camera 13 functions as an area sensor.

  FIG. 9 is a diagram showing the classification of the detection range of the CCD camera 13 referred to in the program installed in the control device 8. As shown in FIG. 9, it is divided into a detection range of the CCD camera 13, a restricted area LA, and a vehicle area CA. The restricted area LA is an area for confirming the presence / absence of passengers and foreign objects. If the presence of any object is detected in the restricted area LA when the movable platform fence 1 is in the closed state, the above-described alarm program is executed. When the movable home fence 1 is in the open state and the upper control device commands the control device 8 to close the door, if the presence of any object is detected in the restricted area LA, the door closing stop program described above is executed. The The vehicle area CA is an area for confirming arrival of the vehicle 9. When arrival of the vehicle 9 is confirmed in the vehicle area CA, the opening operation of the movable platform fence 1 is permitted.

  As described above, the movable home fence 1 according to the embodiment and the modification includes the laser sensor 7 or the CCD camera 13 and can detect the arrival of the vehicle 9. When the arrival of the vehicle 9 is not detected, the opening of the movable home fence 1 can be stopped.
