Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in the home door device as described above, the detection area of an obstacle is set in the space between the home door device and the railway vehicle stopped on the platform. The detection area of an obstacle is set so as not to detect the railway vehicle stopped on the platform and the home door device. And, regardless of whether the railway vehicle is on the platform, the detection area of an obstacle is set. For this reason, since the detection area has to be set based on the railway vehicle in service, there is a limit to the detection accuracy of an obstacle.

Means for Solving the Problems

[0005] An obstacle detection device that solves the above problems comprises: an occupancy information acquisition unit that acquires occupancy information indicating whether or not a railway vehicle running on the track is present on the platform; a setting unit that sets at least one of the detection area and detection sensitivity of a detection sensor that detects obstacles present in a detection area around a platform door device that separates the platform and the track and opens and closes the entrances and exits through which passengers board and alight the railway vehicle, based on the occupancy information; and an output unit that outputs the detection result of the detection sensor to the outside. The setting unit sets at least one of the detection area and detection sensitivity to a second setting that is different from the first setting when the occupancy information indicates that the railway vehicle is present on the platform, if the occupancy information indicates that the railway vehicle is present on the platform.

[0006] According to the above configuration, the track presence information acquisition unit can determine whether or not a railway vehicle is present on the platform. If the railway vehicle is not present on the platform, the setting unit sets a second setting that is different from the first setting used when the railway vehicle is present on the platform. Therefore, by having the detection sensors perform different detections depending on whether the railway vehicle is present on the platform or not, false detections can be reduced while accurately detecting passengers entering the tracks.

[0007] With respect to the above-mentioned obstruction detection device, it is preferable that the detection area of ​​the first setting is on the platform and set between the stationary railway vehicle and the platform door device.

[0008] With respect to the above-mentioned obstacle detection device, it is preferable that the detection area of ​​the second setting is wider than the detection area of ​​the first setting. With respect to the above-mentioned obstruction detection device, it is preferable that the detection area of ​​the second setting includes the upper part of the platform door device within the detection area of ​​the first setting.

[0009] With respect to the above-mentioned obstacle detection device, it is preferable that the detection area of ​​the second setting includes the upper part of the track within the detection area of ​​the first setting. With respect to the above-mentioned obstruction detection device, it is preferable that the detection area of ​​the second setting includes the platform side of the entrance / exit in addition to the detection area of ​​the first setting.

[0010] The above-mentioned obstacle detection device is equipped with a distance information acquisition unit that acquires distance information indicating the distance between the railway vehicle and the platform, and the setting unit preferably, when the railway vehicle is not on the platform, widens the detection area of ​​the detection sensor when the distance is a first distance, and increases the detection sensitivity of the detection sensor when the distance is a second distance which is longer than the first distance, and increases the detection sensitivity of the detection sensor when the distance is a second distance.

[0011] The above-mentioned obstruction detection device is equipped with a type information acquisition unit that acquires type information of the railway vehicle, and the setting unit preferably performs at least one of the following: when the railway vehicle is not present on the platform, and the railway vehicle entering the platform is of a type that does not stop on the platform, the detection area of ​​the detection sensor is wider than when the railway vehicle is of a type that stops on the platform, and the detection sensitivity of the detection sensor is higher than when the railway vehicle is of a type that stops on the platform.

[0012] The above-mentioned obstacle detection device is equipped with a speed information acquisition unit that acquires speed information of the railway vehicle, and the setting unit preferably, when the railway vehicle is not on the platform, widens the detection area of ​​the detection sensor when the time until the railway vehicle enters the platform is 1 hour, and increases the detection sensitivity of the detection sensor when the time is 2 hours, which is longer than the 1 hour.

[0013] With respect to the above-mentioned obstruction detection device, it is preferable that the output unit outputs the detection result to a general control panel that outputs opening and closing commands to multiple platform door devices when the detection sensor detects an obstruction while the railway vehicle is not present on the platform.

[0014] The above-mentioned obstruction detection device is preferably equipped with an abnormality detection information acquisition unit that acquires abnormality detection information on the platform from a camera that detects abnormalities on the platform, and the output unit preferably outputs the detection result to the integrated control panel indicating that the degree of danger is higher than when only the detection sensor detects an obstruction, when the detection sensor has detected an obstruction and the camera has detected an abnormality on the platform, even when the railway vehicle is not on the platform.

[0015] Regarding the above-mentioned obstruction detection device, it is preferable that the platform door device comprises a door pocket that is less than the height of an average adult, and a door that is housed in the door pocket and opens and closes the boarding / alighting area.

[0016] A method for detecting obstacles that solves the above problems includes: an occupancy information acquisition step of acquiring occupancy information indicating whether or not a railway vehicle running on a track is present on a platform; a setting step of setting at least one of the detection area and detection sensitivity of a detection sensor that detects obstacles present in a detection area around a platform door device that separates the platform and the track and opens and closes the entrances and exits through which passengers board and alight the railway vehicle, based on the occupancy information; and an output step of outputting the detection result of the detection sensor to the outside. In the setting step, if the occupancy information indicates that the railway vehicle is not present on the platform, at least one of the detection area and detection sensitivity is set to a second setting that is different from the first setting when the occupancy information indicates that the railway vehicle is present on the platform.

[0017] According to the above method, in the track presence information acquisition step, it is possible to determine whether or not a railway vehicle is present on the platform. If the railway vehicle is not present on the platform, a second setting different from the first setting used when the railway vehicle is present on the platform is set. Therefore, by having the detection sensors perform different detections depending on whether the railway vehicle is present on the platform or not, false detections can be reduced while accurately detecting passengers entering the tracks.

[0018] A program for detecting obstacles that solves the above problems is performed by a computer, which performs the following steps: an acquisition step of location information that acquires location information indicating whether or not a railway vehicle running on the track is present on the platform; a setting step of setting at least one of the detection area and detection sensitivity of a detection sensor that detects obstacles present in the detection area around a platform door device that separates the platform and the track and opens and closes the entrances and exits for passengers to board and alight the railway vehicle, based on the location information; and an output step of outputting the detection result of the detection sensor to the outside. In the setting step, if the location information indicates that the railway vehicle is not present on the platform, at least one of the detection area and detection sensitivity is set to a second setting that is different from the first setting when the location information indicates that the railway vehicle is present on the platform.

[0019] According to the above program, in the track presence information acquisition step, it is possible to determine whether or not a railway vehicle is present on the platform. If the railway vehicle is not present on the platform, the system is set to a second setting, which is different from the first setting used when the railway vehicle is present on the platform. Therefore, by having the detection sensors perform different detections depending on whether or not a railway vehicle is present on the platform, false detections can be reduced while accurately detecting passengers entering the tracks.

[0020] The home door device that solves the above problems includes an opening and closing part that partitions a platform and a track and opens and closes an entrance / exit through which passengers board and alight from a railway vehicle, a detection sensor that detects an obstacle existing in a detection area around the opening and closing part, an on-line information acquisition part that acquires on-line information indicating whether the railway vehicle running on the track is present on the platform, a setting part that sets at least one of the detection area and the detection sensitivity of the detection sensor based on the on-line information, and an output part that outputs the detection result of the detection sensor to the outside. When the on-line information indicates that the railway vehicle is not present on the platform, the setting part sets at least one of the detection area and the detection sensitivity to a second setting different from a first setting when the on-line information indicates that the railway vehicle is present on the platform.

[0021] According to the above configuration, the on-line information acquisition part can grasp whether the railway vehicle is present on the platform. When the railway vehicle is not present on the platform, the setting part sets it to a second setting different from the first setting when the railway vehicle is present on the platform. Therefore, by making the detection sensor perform different detections when the railway vehicle is present on the platform and when it is not present, it is possible to reduce false detections while accurately detecting the intrusion of passengers onto the track.

Advantages of the Invention

[0022] According to the present invention, it is possible to accurately detect the intrusion of passengers onto the track while reducing false detections.

[0024] The first embodiment of the obstruction detection device and platform door system will be described below with reference to Figures 1 to 5. The platform door system is installed on the station platform. The obstruction detection device is installed on the platform door system.

[0025] As shown in Figure 1, Station 1 has a track 2 on which railway vehicles run, and a platform 3 along the track 2. Multiple platform door devices 5 are installed in a row along the extending direction of the platform 3.

[0026] (Platform door device 5) The platform door system 5 separates the platform 3 side from the track 2 side. The platform door system 5 comprises a door pocket 10, a first door 11, and a second door 12. The door pocket 10 is fixed to the platform 3 and is less than the height of an average adult. The first door 11 is located to the left of the door pocket 10 when viewed from the platform 3 side, and the second door 12 is located to the right of the door pocket 10. The first door 11 and the second door 12 are stored in the door pocket 10. The first door 11 and the second door 12 are sliding doors, supported by guide members such as linear guides (not shown), and are installed to move back and forth in the opening and closing direction from the door pocket 10. The first door 11 and the second door 12 open and close the boarding / alighting opening E on the platform 3. The boarding / alighting opening E is the opening through which passengers board and alight the railway vehicle, and is located between the door pockets 10. The first door 11 is supported by the door pocket 10 so as to be movable in the opening and closing direction. The first door 11 is installed so as to be able to move forward and backward from the left side of the door pocket 10. The second door 12 is supported by the door pocket 10 so as to be movable in the opening and closing direction. The second door 12 is installed so as to be able to move forward and backward from the right side of the door pocket 10. One entrance / exit E is opened and closed by two platform door devices 5. That is, the entrance / exit E is opened and closed by the second door 12 of the platform door device 5 located on the left side when viewed from the platform 3 side, and the first door 11 of the platform door device 5 located on the right side. The first door 11 and the second door 12 correspond to the opening and closing parts. Note that the first door 11 and the second door 12 that open and close one entrance / exit E may be considered as one platform door device. Also, the doors may be installed so as to be able to move forward and backward from only one of the left or right sides of the door pocket 10.

[0027] The platform door device 5 is equipped with a detection sensor 20. The detection sensor 20 performs obstruction detection, detecting objects present in the detection area AS around the platform door device. The detection sensor 20 detects the presence or absence of objects located between the door pockets 10 on the track 2 side of the first door 11 and second door 12 on the platform 3. The detection sensor 20 is installed in a first box 21 fixed to the right of the rear side of the door pocket 10 on the track 2 side. A second box 22 is fixed to the left of the rear side of the door pocket 10. The detection sensor 20 emits light and receives light reflected from objects. The detection sensor 20 scans the light by rotating a reflective mirror to form the detection area AS. The detection sensor 20 forms the detection area AS between the first box 21 and the second box 22. Objects detected by the detection sensor 20 include people, obstructions, and the ground. The detection sensor 20 measures the distance to the object from which light is reflected using the time-of-flight (TOF) principle. The detection sensor 20 identifies the position of the object from which light is reflected based on the rotation angle of the reflective mirror and the distance to the object. The detection sensor 20 determines the range of the detection area AS by setting whether or not to include the position of the object from which light is reflected within the detection area AS.

[0028] Next, with reference to Figure 2, the electrical configuration of the platform door device 5 will be described. As shown in Figure 2, each platform door device 5 is connected via a communication line L to a central control panel 4 installed at each platform 3. The platform door device 5 comprises a door control unit 13, a first drive unit 14, a second drive unit 15, a detection sensor 20, and a notification unit 16. The first drive unit 14, the second drive unit 15, the detection sensor 20, and the notification unit 16 are connected to the door control unit 13. The central control panel 4 receives information on the operation status and location of railway vehicles from the higher-level system, the operation management system 50.

[0029] (Door control unit 13) The door control unit 13 may be configured as one or more processors that execute various processes according to a computer program (software). The processes executed by the door control unit 13, i.e., the processor, include an obstacle detection method. The obstacle detection method includes a track occupancy information acquisition step, a setting step, and an output step, which will be described later. The door control unit 13 may also be configured as a circuit including one or more dedicated hardware circuits, such as application-specific integrated circuits (ASICs), or a combination thereof, that execute at least some of the various processes. The processor includes a CPU and memory such as RAM and ROM. The memory stores program code or instructions configured to cause the CPU to execute the processes. The memory, i.e., computer-readable media, includes any available media that can be accessed by a general-purpose or dedicated computer. The programs stored in the computer-readable media include an obstacle detection program. The obstacle detection program causes the computer to execute the track occupancy information acquisition step, the setting step, and the output step.

[0030] The first drive unit 14 and the second drive unit 15 are driven and controlled by the door control unit 13. The first drive unit 14 is equipped with a motor (not shown) and drives the first door 11 in the opening and closing direction by transmitting the driving force of the motor to the first door 11 via a belt (not shown). The second drive unit 15 is equipped with a motor (not shown) and drives the second door 12 in the opening and closing direction by transmitting the driving force of the motor to the second door 12 via a belt (not shown). The door control unit 13 receives a fully closed signal from a position sensor (not shown) that detects when the first door 11 and the second door 12 are fully closed, indicating that the first door 11 and the second door 12 are fully closed.

[0031] The door control unit 13 controls the opening and closing of the first door 11 and the second door 12 according to the detection result of the detection sensor 20. The door control unit 13 opens and closes the first door 11 by controlling the drive of the first drive unit 14, and opens and closes the second door 12 by controlling the drive of the second drive unit 15. The detection result of the detection sensor 20 is transmitted from the platform door device 5 on the left side of Figure 1 to the platform door device 5 on the right side. In other words, the platform door device 5 controls the drive of the second door 12 according to the detection result of the detection sensor 20 installed on itself, and controls the opening and closing of the first door 11 according to the detection result of the detection sensor 20 installed on the platform door device 5 located to its left. The door control unit 13 opens and closes the first door 11 and the second door 12 according to the opening and closing command from the integrated control panel 4.

[0032] (Sensor control unit 30) The door control unit 13 also serves as the sensor control unit 30 that controls the detection sensor 20. The door control unit 13 includes a track occupancy information acquisition unit 31, a setting unit 32, and an output unit 33. The track occupancy information acquisition unit 31 acquires track occupancy information indicating whether or not a railway vehicle running on the track 2 is present at platform 3. The track occupancy information acquisition unit 31 acquires track occupancy information from the integrated control panel 4. "Present" means that at least a part of the railway vehicle is on platform 3. Note that "present" also includes the state in which the railway vehicle is stopped at platform 3 and the state in which the railway vehicle is passing through platform 3. Note that the track occupancy information may also be the position information of the railway vehicle or distance information indicating the distance between the railway vehicle and platform 3, and the track occupancy information acquisition unit 31 determines whether or not the railway vehicle is present at platform 3 from the position information and distance information.

[0033] The sensor control unit 30 causes the detection sensor 20 to detect an obstruction when the first door 11 and the second door 12 are fully closed and when they are closed from a fully open position. When the detection sensor 20 detects an obstruction during the closing operation of the first door 11 and the second door 12, the door control unit 13 stops the driving of the first drive unit 14 and the second drive unit 15 to stop the first door 11 and the second door 12. Alternatively, the door control unit 13 drives the first drive unit 14 and the second drive unit 15 in the opening direction to move the first door 11 and the second door 12 in the opening direction. When the detection sensor 20 no longer detects an obstruction, the door control unit 13 drives the first drive unit 14 and the second drive unit 15 in the closing direction to move the first door 11 and the second door 12 in the closing direction.

[0034] (Detection sensor 20) Incidentally, the detection area AS of the detection sensor 20 is set not to detect railway vehicles stopped on platform 3 or platform door devices 5. For this reason, the detection area AS of the detection sensor 20 must be set based on the presence of railway vehicles. Therefore, the setting unit 32 sets at least one of the detection area AS and detection sensitivity of the detection sensor 20 based on the presence information. Specifically, if the presence information indicates that no railway vehicles are present on platform 3, the setting unit 32 sets at least one of the detection area AS and detection sensitivity to a second setting that is different from the first setting used when the presence information indicates that railway vehicles are present on platform 3. The railway operator can arbitrarily set whether to select only the detection area AS, only the detection sensitivity, or both the detection area AS and detection sensitivity as the second setting.

[0035] As shown in Figure 3, the detection area for the first setting is designated as the first detection area AS1. The first detection area AS1 is located on the platform 3 and is set between the stationary railway vehicle and the platform door device 5.

[0036] As shown in Figure 4, the detection area for the second setting is designated as the second detection area AS2. The second detection area AS2 is wider than the first detection area AS1. The second detection area AS2 includes the upper part of the platform door device 5 within the first detection area AS1. Because the second detection area AS2 includes the upper part of the platform door device 5, the detection sensor 20 can detect passengers climbing over the platform door device 5 when no trains are present.

[0037] The setting unit 32 increases the detection sensitivity of the detection sensor 20 in the second setting to a higher level than the detection sensitivity of the first setting. In the first setting, when a railway vehicle is present, it is necessary to avoid false detection of railway vehicles and passengers. On the other hand, in the second setting, when no railway vehicles are present, it is desirable to detect as many people as possible who are climbing over the platform door device 5 or attempting to enter the track 2, so a higher detection sensitivity is preferable.

[0038] When the detection sensor 20 detects an obstruction, it outputs a detection signal to the sensor control unit 30. The output unit 33 outputs the detection result of the detection sensor 20 to the outside. If the detection sensor 20 detects an obstruction when no railway vehicle is present on the platform 3, the output unit 33 outputs the detection result to the integrated control panel 4. The detection result may include an emergency stop signal to stop the railway vehicle. The output unit 33 also causes the notification unit 16 to notify when the detection sensor 20 detects an obstruction. The notification unit 16 outputs at least one of light and sound.

[0039] (Obstacle detection processing) Next, with reference to Figure 5, the obstacle detection process by the platform door device 5 will be explained.

[0040] As shown in Figure 5, the sensor control unit 30 acquires occupancy information (step S1). That is, the occupancy information acquisition unit 31 acquires occupancy information from the integrated control panel 4. Occupancy information is information that indicates a train is occupying a platform 3 when at least a part of the train is on the platform 3. Step S1 corresponds to the occupancy information acquisition step.

[0041] Next, the sensor control unit 30 determines whether or not a railway vehicle is present (step S2). That is, the setting unit 32 determines whether or not a railway vehicle is present on platform 3 based on the presence information acquired by the presence information acquisition unit 31. The setting unit 32 determines that a railway vehicle is present if the presence information indicates that a vehicle is present, and determines that a railway vehicle is not present if the presence information indicates that a vehicle is not present.

[0042] Then, if the setting unit 32 determines that no railway vehicles are present (step S2: NO), it sets the detection of the detection sensor 20 to the second setting (step S6) and proceeds to step S4. That is, the setting unit 32 sets at least one of the detection area AS and detection sensitivity of the detection sensor 20 to the second setting. By including the upper part of the platform door device 5 in the second detection area AS2, the detection sensor 20 can detect passengers climbing over the platform door device 5 when no railway vehicles are present. Furthermore, since the detection sensitivity of the second setting is higher than that of the first setting, it can detect people climbing over the platform door device 5 or people attempting to enter the track 2. Note that step S2 corresponds to the setting step.

[0043] On the other hand, if the setting unit 32 determines that a railway vehicle is present (step S2: YES), it sets the detection of the detection sensor 20 to the first setting (step S3). That is, the setting unit 32 sets the detection area AS and detection sensitivity of the detection sensor 20 to the first setting. This allows for the detection of obstacles while suppressing false detections of railway vehicles and passengers when a railway vehicle is present. Note that step S3 corresponds to the setting step.

[0044] Next, the sensor control unit 30 determines whether or not there is detection from the detection sensor 20 (step S4). That is, the sensor control unit 30 determines whether or not a detection signal is input from the detection sensor 20 which is set to the first setting or the second setting.

[0045] Then, if the sensor control unit 30 determines that no detection signal has been input from the detection sensor 20 (step S4: NO), it determines whether a predetermined time has elapsed (step S7). That is, for a predetermined time after acquiring the presence information in step S1, the sensor control unit 30 has the detection sensor 20 detect obstacles based on the settings derived from the acquired presence information (step S7: NO). The setting unit 32 sets to the first setting when it acquires presence information that a railway vehicle is on platform 3. Then, the sensor control unit 30 terminates processing when a predetermined time has elapsed since acquiring the presence information in step S1 (step S7: YES).

[0046] On the other hand, if the sensor control unit 30 determines that a detection signal has been input from the detection sensor 20 (step S4: YES), it outputs an abnormality (step S5) and terminates the process. That is, the output unit 33 outputs the detection result to the integrated control panel 4. In addition, when the detection sensor 20 detects something, the output unit 33 causes the notification unit 16 to notify. The notification unit 16 outputs at least one of light and sound. Step S5 corresponds to the output step.

[0047] Next, the effects of the first embodiment will be described. (1-1) The track presence information acquisition unit 31 can determine whether or not a railway vehicle is present on platform 3. If the railway vehicle is not present on platform 3, the setting unit 32 sets a second setting that is different from the first setting used when the railway vehicle is present on platform 3. As a result, the detection sensor 20 performs different detections depending on whether the railway vehicle is present on platform 3 or not, reducing false detections while accurately detecting passengers entering the track 2.

[0048] (1-2) In the first detection area AS, the presence of a passenger remaining between the railway vehicle on platform 3 and the platform door device 5 can be detected, and if there is no railway vehicle, the intrusion of a passenger onto the track 2 can be detected in a second detection area AS, which is different from the first detection area AS.

[0049] (1-3) The detection area AS when no railway vehicle is present on platform 3 is wider than the detection area AS when a railway vehicle is present on platform 3, thus reducing false detections while accurately detecting passengers entering the track 2.

[0050] (1-4) When no railway vehicle is present on platform 3, the detection area AS includes the upper part of the platform door device 5, so it is possible to detect a person attempting to climb over the platform door device 5 and enter the track 2.

[0051] (1-5) The integrated control panel 4 can determine that the detection sensor 20 has detected an obstruction. (1-6) Since platform screen doors 5 that are shorter than the height of an adult are likely to be climbed over by passengers, it is effective to adopt an obstacle detection device.

[0052] (Second Embodiment) A second embodiment of the platform screen door system will be described below with reference to Figure 6. This embodiment of the platform screen door system differs from the first embodiment in that the detection of the detection sensor is set according to the distance between the railway vehicle and the platform. The following description will focus on the differences from the first embodiment.

[0053] (Sensor control unit 30) The sensor control unit 30 further includes a distance information acquisition unit (not shown). The distance information acquisition unit acquires distance information indicating the distance between the railway vehicle and the platform 3 from the integrated control panel 4. The integrated control panel 4 acquires distance information indicating the distance between the railway vehicle and the platform 3 as position information of the railway vehicle from the operation management system 50. Alternatively, the integrated control panel 4 or the distance information acquisition unit may calculate the distance information indicating the distance between the railway vehicle and the platform 3 from the position information of the railway vehicle.

[0054] The setting unit 32 sets the detection of the detection sensor 20 to the third setting when the distance is the first distance if the railway vehicle is not present on platform 3. The first distance is less than a predetermined distance indicating proximity to station 1, and the second distance is the predetermined distance or greater. In the third setting, the setting unit 32 widens the detection area AS of the detection sensor 20 compared to the second distance, and increases the detection sensitivity of the detection sensor 20 compared to the second distance. When the railway vehicle is not present on platform 3, the setting unit 32 sets the detection of the detection sensor 20 to the second setting if the distance is the predetermined distance or greater than the second distance.

[0055] (Obstacle detection processing) Next, with reference to Figure 6, the obstacle detection process of the platform door device 5 will be explained. As shown in Figure 6, steps S1 to S7 are carried out in the same manner as in the first embodiment.

[0056] Following step S6, the sensor control unit 30 acquires distance information of the railway vehicle (step S11). That is, the distance information acquisition unit acquires distance information from the integrated control panel 4. The distance information is the shortest distance between the railway vehicle and the platform 3. Alternatively, the distance information may be the distance between any position on the platform 3 and any position on the railway vehicle.

[0057] Next, the sensor control unit 30 determines whether the distance between the railway vehicle and the platform 3 is less than a predetermined distance (step S12). That is, the setting unit 32 determines whether the distance between the railway vehicle and the platform 3 is less than a predetermined distance based on the distance information acquired by the distance information acquisition unit.

[0058] If the setting unit 32 determines that the distance between the railway vehicle and the platform 3 is greater than or equal to a predetermined distance (step S12: NO), the distance between the railway vehicle and the platform 3 remains as the second setting (second distance) and the process proceeds to step S4.

[0059] On the other hand, if the setting unit 32 determines that the distance between the railway vehicle and the platform 3 is less than a predetermined distance (step S12: YES), it sets the detection of the detection sensor 20 to the third setting (step S13) and proceeds to step S4. That is, the setting unit 32 sets the detection area AS and detection sensitivity of the detection sensor 20 to the third setting. When the railway vehicle is not on the platform 3, it is possible to detect passengers climbing over the platform door device 5 with a wider detection area AS than the second setting. In addition, since the detection sensitivity of the third setting is higher than that of the second setting, it is possible to further detect people climbing over the platform door device 5 or people attempting to enter the track 2.

[0060] Next, the sensor control unit 30 determines whether or not a detection signal is input from the detection sensor 20 set to the first setting, second setting, or third setting. Steps S4, S5, and S7 are the same as in the first embodiment, so their explanation is omitted.

[0061] Next, the effects of the second embodiment will be described. In addition to the effects (1-1) to (1-6) of the first embodiment, the following effects are also achieved. (2-1) The distance between the railway vehicle and platform 3 can be determined, and if the railway vehicle is not on platform 3, the setting unit 32 widens the detection area AS of the detection sensor 20 and increases the detection sensitivity of the detection sensor 20 when the railway vehicle is close to platform 3. Since the degree of danger differs depending on the distance between the railway vehicle and platform 3, the detection sensor 20 can perform different detections depending on the distance.

[0062] (Third embodiment) The third embodiment of the platform screen door system will be described below with reference to Figures 7 and 8. This embodiment of the platform screen door system differs from the first embodiment in that it outputs a message based on the detection of anomalies on the platform. The differences from the third embodiment will be explained below.

[0063] (Camera 40) As shown in Figure 7, multiple cameras 40 are installed on platform 3. The cameras 40 detect abnormalities on platform 3. Specifically, if the captured video contains people or objects moving in a manner different from normal, the cameras 40 determine that an abnormality has occurred and output abnormality detection information to the integrated control panel 4. The cameras 40 have a judgment program that determines whether or not a movement is abnormal. If platform 3 is short, only one camera 40 may be needed.

[0064] (Sensor control unit 30) The sensor control unit 30 further includes an anomaly detection information acquisition unit (not shown). The anomaly detection information acquisition unit acquires anomaly detection information from the camera 40 via the integrated control panel 4 on the platform 3. Alternatively, the anomaly detection information acquisition unit may acquire anomaly detection information from the camera 40 directly on the platform 3.

[0065] When a railway vehicle is not present on platform 3, if the detection sensor 20 detects an obstruction and the camera 40 detects an abnormality on platform 3, the output unit 33 outputs a detection result to the integrated control panel 4 indicating that the level of danger is higher than when only the detection sensor 20 detects an obstruction.

[0066] (Obstacle detection processing) Next, with reference to Figure 8, the obstacle detection process of the platform door device 5 will be explained. As shown in Figure 8, the same process as in the first embodiment is performed up to step S7.

[0067] Following step S6, the sensor control unit 30 determines whether or not there is detection from the detection sensor 20 (step S8). That is, the sensor control unit 30 determines whether or not a detection signal has been input from the detection sensor 20 set to the second setting.

[0068] Then, if the sensor control unit 30 determines that no detection signal has been input from the detection sensor 20 (step S8: NO), it determines whether a predetermined time has elapsed (step S9). In other words, for a predetermined time after acquiring the presence information in step S1, the sensor control unit 30 allows the detection sensor 20 to detect obstacles based on the settings derived from the acquired presence information. The setting unit 32 sets to the first setting when it acquires presence information indicating that a railway vehicle is present at platform 3.

[0069] On the other hand, if the sensor control unit 30 determines that a detection signal has been input from the detection sensor 20 (step S8: YES), it determines whether or not an abnormality has been detected (step S21). That is, the setting unit 32 determines whether or not the abnormality detection information acquisition unit has acquired abnormality detection information.

[0070] Then, if the output unit 33 determines that the abnormality detection information acquisition unit has not acquired any abnormality detection information (step S21: NO), it outputs an abnormality (step S5) and terminates the process. In other words, the output unit 33 outputs the detection result to the integrated control panel 4. Also, when the detection sensor 20 detects something, the output unit 33 causes the notification unit 16 to notify it. The notification unit 16 outputs at least one of light and sound.

[0071] On the other hand, if the output unit 33 determines that the abnormality detection information acquisition unit has acquired abnormality detection information (step S21: YES), it recognizes it as a detection of high risk (step S22). In other words, the output unit 33 gives a detection result that indicates a higher risk than when only the detection sensor 20 has detected an obstruction. The output unit 33 then outputs the detection result to the integrated control panel 4 (step S5). The output unit 33 also causes the notification unit 16 to notify when the detection sensor 20 detects something.

[0072] Next, the effects of the third embodiment will be described. In addition to the effects (1-1) to (1-6) of the first embodiment, the following effects are also achieved. (3-1) When the detection sensor 20 detects an obstruction and the camera 40 detects an abnormality on platform 3, a detection result indicating a high level of danger is output to the integrated control panel 4. Therefore, the integrated control panel 4 can understand that the level of danger is high from the detection result.

[0073] (Other embodiments) Each of the above embodiments can be implemented with the following modifications. Each of the above embodiments and the following modifications can be combined with each other to the extent that they do not contradict each other technically.

[0074] In the second embodiment described above, the detection of the detection sensor 20 was set according to the distance between the railway vehicle and the platform 3. However, instead of the distance between the railway vehicle and the platform 3, the detection of the detection sensor 20 may be set according to the type of railway vehicle. Specifically, the sensor control unit 30 further includes a type information acquisition unit that acquires type information of the railway vehicle. The type information is limited express, express, local, etc., and includes information on whether or not the railway vehicle will stop at station 1. When the railway vehicle is not present at platform 3, the setting unit 32 sets to the third setting if the railway vehicle entering platform 3 is of a type that will not stop at platform 3. In the third setting, the setting unit 32 makes the detection area AS of the detection sensor 20 wider than when the railway vehicle stops at platform 3, and makes the detection sensitivity higher than when the railway vehicle stops at platform 3. The setting unit 32 sets the system to the second setting when no railway vehicle is present at platform 3, and the railway vehicle entering platform 3 is of a type that stops at platform 3. With this configuration, it is possible to determine from the type information whether or not a railway vehicle will stop at platform 3, and when no railway vehicle is present at platform 3, the setting unit 32 widens the detection area AS of the detection sensor 20 and increases the detection sensitivity of the detection sensor 20, at least one of the above. As a result, the detection sensor 20 can perform different detections depending on whether or not a railway vehicle is passing through platform 3.

[0075] ·In the second embodiment described above, the detection of the detection sensor 20 was set according to the distance between the railway vehicle and the platform 3. However, instead of the distance between the railway vehicle and the platform 3, the detection of the detection sensor 20 may be set according to the speed of the railway vehicle. Specifically, the sensor control unit 30 further includes a speed information acquisition unit that acquires speed information of the railway vehicle. The speed information acquisition unit calculates the time until the railway vehicle enters the platform 3 from the speed information. If the railway vehicle is not present at the platform 3, the setting unit 32 sets the detection to the third setting when the time until the railway vehicle enters the platform 3 is the first hour. The first hour is less than a predetermined time indicating proximity to the station 1, and the second hour is the predetermined time or longer. In the third setting, the setting unit 32 widens the detection area AS of the detection sensor 20 compared to the second hour, which is longer than the predetermined time, and increases the detection sensitivity of the detection sensor 20 compared to the second hour. The setting unit 32 sets the system to the second setting when the time until the railway vehicle arrives at platform 3 is the second time, provided that the railway vehicle is not currently at platform 3. With this configuration, the time until the railway vehicle arrives at platform 3 can be determined from the position information and speed information. When the railway vehicle is not currently at platform 3, the setting unit 32 widens the detection area AS of the detection sensor 20 and increases the detection sensitivity of the detection sensor 20 when the railway vehicle is close to platform 3. As a result, the detection sensor 20 can perform different detections depending on the time until the railway vehicle arrives at platform 3.

[0076] In each of the above embodiments, the second detection area AS2, which is the second setting detection area AS, includes the upper part of the platform door device 5 within the first detection area AS1, which is the first setting detection area AS. However, as shown in Figure 9, the third detection area AS3, which is the second setting detection area AS, may include the upper part of the track 2 within the first detection area AS1. The range of the third detection area AS3 above the track 2 can be set arbitrarily. With this configuration, when no railway vehicle is on the platform 3, the detection area includes the upper part of the track 2, so it is possible to detect a person who has entered the track 2. Note that the second setting detection area AS may include the upper part of the platform door device 5 and the upper part of the track 2.

[0077] In each of the above embodiments, the second detection area AS2, which is the second setting detection area AS, includes the upper part of the platform door device 5 in the first detection area AS1, which is the first setting detection area AS. However, as shown in Figure 10, the fourth detection area AS4, which is the second setting detection area AS, may include the platform 3 side of the entrance E in the first detection area AS1. Detection on the platform 3 side of the first door 11 and the second door 12 is detected from the gap between the first door 11 and the second door 12 and the floor surface, or from the frame-shaped gaps between the frames of the first door 11 and the second door 12. With this configuration, when there is no railway vehicle on the platform 3, the detection area AS includes the platform 3 side of the entrance E of the platform door device 5, so that a person approaching the entrance E can be detected. The second setting detection area AS may include at least one of the upper part of the platform door device 5, the upper part of the track 2, and the platform 3 side of the entrance E.

[0078] In each of the above embodiments, the door control unit 13 also functions as the sensor control unit 30. However, as shown in Figure 11, an obstacle detection device 6 may be provided separately from the platform door device 5. The obstacle detection device 6 comprises a detection sensor 20 and a sensor control unit 130 similar to the sensor control unit 30. The sensor control unit 130 includes a train occupancy information acquisition unit 31, a setting unit 32, and an output unit 33. The sensor control unit 130 acquires train occupancy information from the integrated control panel 4 via the door control unit 13. The sensor control unit 130 outputs the detection result of the detection sensor 20 to the door control unit 13.

[0079] In each of the above embodiments, as shown in Figure 12, the integrated control panel 4 may also be provided with a train occupancy information acquisition unit 41 and a sensor setting unit 42. The door control unit 13 includes an output unit 33. When the train occupancy information acquisition unit 41 acquires train occupancy information, the sensor setting unit 42 sets at least one of the detection area AS and detection sensitivity of the detection sensor 20. The sensor control unit 30 of the door control unit 13 controls the detection sensor 20 based on the setting of the sensor setting unit 42. In this way, the settings of the detection sensors 20 of the platform door devices 5 connected to the integrated control panel 4 can be set simultaneously from the integrated control panel 4.

[0080] In each of the above embodiments, the presence of a railway vehicle was determined based on the presence information received from the operation management system 50. However, the presence information of a railway vehicle may also be obtained based on at least one of the following: track circuit information that can determine whether or not a railway vehicle is present, location information from a Global Positioning System (GPS) installed on the railway vehicle, and level crossing operation information.

[0081] In each of the above embodiments, the presence of a railway vehicle was determined based on the presence information received from the operation management system 50. However, information on whether or not a railway vehicle is located on platform 3 may be obtained from a camera installed on platform 3.

[0082] In each of the above embodiments, a waist-high type platform door device 5 was used, in which the height of the door pocket 10 is less than the height of an average passenger. However, a full-height type platform door device may also be used, in which the height of the door pocket 10 is greater than the height of an average passenger. Even with a full-height type platform door device, even if passengers do not climb over the platform door device, the detection sensor 20 can perform different detections depending on whether a railway vehicle is present on the platform 3 or not, thereby reducing false detections and enabling accurate detection of passengers entering the tracks 2.

[0083] In each of the above embodiments, if the structure is composed of multiple objects, those multiple objects may be integrated, and conversely, if the structure is composed of a single object, it may be divided into multiple objects. Whether or not the objects are integrated, the structure should be configured in a way that achieves the objective of the invention.

[0084] In each of the above embodiments, if multiple functions are provided in a distributed manner, some or all of those functions may be consolidated and provided together. Conversely, if multiple functions are consolidated and provided together, some or all of those functions may be distributed and provided together. Regardless of whether the functions are consolidated or distributed, it is sufficient that the objective of the invention can be achieved.
