Modes for Carrying Out the Invention

[0009] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0010] FIG. 1 is a plan view showing a schematic configuration of a home door control system according to an embodiment of the present invention, and FIG. 2 is a block diagram of the home door control system according to an embodiment of the present invention. The home door control system 1 according to the embodiment is configured to open the vehicle door of the train and the home door installed on the platform in conjunction with each other when the train enters the platform of the station and stops at a fixed position, and to close the vehicle door of the train and the home door installed on the platform in conjunction with each other when the train departs from the station.

[0011] Referring to FIGS. 1 and 2, the home door control system 1 according to the embodiment includes an on-vehicle device 30 mounted on the train 10 and a home door control device 70 installed on the platform 50 of the station. The train 10 has a plurality of vehicle doors 11, and a plurality of home doors 51 are installed on the platform 50. In FIG. 1, the train 10 is composed of a single vehicle having two vehicle doors 11 on each of the left and right sides, and two home doors 51 are installed on the platform 50. However, this is for convenience of explanation, and the train 10 may be composed of a plurality of vehicles, and each vehicle constituting the train 10 may have an arbitrary number of vehicle doors 11 on either the left or right side or on both the left and right sides. Also, it is sufficient that a plurality of home doors 51 are installed on the platform 50, and the number of home doors 51 is arbitrary.

[0012] In the present embodiment, the on-vehicle device 30 mounted on the train 10 includes an on-vehicle radio 31, an on-vehicle radio cooperation unit 33, a vehicle door control unit 35, and a notification unit 37, and the home door control device 70 installed on the platform 50 includes a ground radio 71, a ground radio cooperation unit 73, a home door control unit 75, and an alarm unit 77.

[0013] When the train 10 is within a predetermined range from the station, the on-vehicle radio 31 of the on-vehicle device 30 and the ground radio 71 of the home door control device 70 can communicate wirelessly with each other. Also, in the on-vehicle device 30, the on-vehicle radio cooperation unit 33 is connected to the on-vehicle radio 31, and in the home door control device 70, the ground radio cooperation unit 73 is connected to the ground radio 71. Therefore, in the present embodiment, from when the train 10 approaches the station and enters the predetermined range until the train 10 departs from the station and exits the predetermined range, wireless communication can be performed between the on-vehicle radio cooperation unit 33 of the on-vehicle device 30 and the ground radio cooperation unit 73 of the home door control device 70 via the on-vehicle radio 31 and the ground radio 71.

[0014] In the on-vehicle device 30, a signal from the conductor door switch 41 is input to the on-vehicle radio cooperation unit 33. The conductor door switch 41 is installed in the conductor's cabin or the driver's cab of the train 10. The conductor door switch 41 is a switch that is operated by the crew or driver (hereinafter referred to as "crew, etc.") of the train 10 to open and close some or all of the plurality of vehicle doors 11 of the train 10. The conductor door switch 41 is configured to output a signal corresponding to the operation of the crew, etc., specifically, an opening operation signal for opening the vehicle door 11 or a closing operation signal for closing the vehicle door 11 to the on-vehicle radio cooperation unit 33. That is, an opening operation signal and a closing operation signal can be input to the on-vehicle radio cooperation unit 33 from the conductor door switch 41.

[0015] Also, a signal from the emergency reporting device 43 is input to the on-vehicle radio cooperation unit 33. The emergency reporting device 43 is installed in the passenger compartment of the train 10. The emergency reporting device 43 is a device mainly operated by the passengers of the train 10 when an emergency occurs in the passenger compartment of the train 10. The emergency reporting device 43 is configured to output a signal (SOS signal) indicating that an emergency has occurred in the passenger compartment to the on-vehicle radio cooperation unit 33 when operated by the passengers. That is, an SOS signal can be input to the on-vehicle radio cooperation unit 33 from the emergency reporting device 43.

[0016] Furthermore, a signal from the emergency door cock 45 is input to the on-vehicle wireless communication unit 33. The emergency door cock 45 is installed in the passenger compartment of the train 10. The emergency door cock 45 is a device mainly operated by the passengers of the train 10 to put the vehicle door 11 of the train 10 in a state where it can be manually opened in case of an emergency in the passenger compartment of the train 10. When the emergency door cock 45 is operated by a passenger, it is configured to output a door cock operation signal to the on-vehicle wireless communication unit 33 and the vehicle door control unit 35. That is, a door cock operation signal can be input from the emergency door cock 45 to each of the on-vehicle wireless communication unit 33 and the vehicle door control unit 35.

[0017] As described above, the on-vehicle wireless communication unit 33 is capable of performing wireless communication with the ground wireless communication unit 73. Also, in the present embodiment, the on-vehicle wireless communication unit 33 is configured to be able to give, for example, a vehicle door opening / closing command to the vehicle door control unit 35 and a notification command to the notification unit 37.

[0018] The vehicle door control unit 35 is configured to open and close the vehicle door 11 of the train 10 based on the vehicle door opening / closing command from the on-vehicle wireless communication unit 33. Specifically, when a vehicle door opening command is given to the vehicle door control unit 35 from the on-vehicle wireless communication unit 33, the vehicle door control unit 35 opens one or more of the plurality of vehicle doors 11 of the train 10 that are the target of the command. Also, when a vehicle door closing command is given to the vehicle door control unit 35 from the on-vehicle wireless communication unit 33, the vehicle door control unit 35 closes one or more of the plurality of vehicle doors 11 of the train 10 that are the target of the command. Furthermore, when a door cock operation signal is input from the emergency door cock 45 to the vehicle door control unit 35, it is configured to put all the vehicle doors 11 of the train 10 in a state where they can be manually opened.

[0019] The notification unit 37 is configured to notify various information to the crew and the like based on the notification command from the on-vehicle wireless communication unit 33. For example, when an emergency notification command is given to the notification unit 37 from the on-vehicle wireless communication unit 33, the notification unit 37 notifies the crew and the like that an emergency has occurred in the passenger compartment of the train 10.

[0020] Here, when the emergency reporting device 43 is operated by a passenger during the running of the train 10, the notification unit 37 notifies the crew and the like that an emergency has occurred in the passenger compartment of the train 10, and the train 10 is stopped by the crew and the like who have received the notification. Alternatively, when the emergency door cock 45 is operated by a passenger during the running of the train 10, the train 10 automatically stops. That is, when the emergency reporting device 43 and / or the emergency door cock 45 is operated, the train 10 will stop.

[0021] In the platform door control device 70, the detection result of the fixed-position stop detection unit 81 is input to the ground wireless communication unit 73. The fixed-position stop detection unit 81 includes, for example, a distance measuring sensor that measures the position of the front of the train 10, and is configured to be able to detect that the train 10 that has entered the platform 50 of the station has stopped at a fixed position. However, it is not limited to this. The fixed-position stop detection unit 81 only needs to be able to detect that the train 10 has stopped at a fixed position, and may be composed of an on-vehicle unit provided at the lower front of the train 10 and a ground unit installed at or near the fixed position.

[0022] As described above, the ground wireless communication unit 73 is capable of performing wireless communication with the on-vehicle wireless communication unit 33. Also, in the present embodiment, the ground wireless communication unit 73 is configured to be able to, for example, give a platform door opening / closing command to the platform door control unit 75 and give an alarm command to the alarm unit 77.

[0023] The platform door control unit 75 is configured to open and close a plurality of platform doors 51 installed on the platform 50 of the station based on the platform door opening / closing command from the ground wireless communication unit 73. Specifically, when the platform door control unit 75 receives a platform door opening command from the ground wireless communication unit 73, it opens the plurality of platform doors 51 installed on the platform 50. Also, when the platform door control unit 75 receives a platform door closing command from the ground wireless communication unit 73, it closes the plurality of platform doors 51 installed on the platform 50. Here, "opening (closing) a plurality of platform doors 51" includes opening (closing) all of the plurality of platform doors 51 installed on the platform 50 and opening (closing) a part of the plurality of platform doors 51 installed on the platform 50.

[0024] The alarm unit 77 is configured to issue an alarm based on an alarm command from the ground wireless communication unit 73. This alarm mainly aims to prompt the users on the platform 50 to pay attention and / or prompt the station staff of the station to take actions to ensure the safety of the users on the platform 50.

[0025] Next, with reference to FIGS. 3 to 5, an operation example of the platform door control system 1 (the on-vehicle device 30 and the platform door control device 70) according to the embodiment will be described.

[0026] FIG. 3 is a flowchart showing an example of the normal operation of the platform door control system 1 (the on-vehicle device 30 and the platform door control device 70).

[0027] When the train 10 approaches the station and enters the predetermined range, the platform door control system 1 establishes wireless communication between the on-vehicle wireless communication unit 33 of the on-vehicle device 30 and the ground wireless communication unit 73 of the platform door control device 70 (step S1).

[0028] Although not particularly limited, for example, the ground wireless communication unit 73 of the home door control device 70 constantly transmits a response request signal via the ground wireless device 71, and the on-vehicle wireless communication unit 33 of the on-vehicle device 30 of the train 10 approaching the station receives the response request signal via the on-vehicle wireless device 31 and returns a response signal to the ground wireless communication unit 73 of the home door control device 70. Thereby, wireless communication is established between the on-vehicle wireless communication unit 33 of the on-vehicle device 30 and the ground wireless communication unit 73 of the home door control device 70, and wireless communication between the on-vehicle device 30 and the home door control device 70 becomes possible.

[0029] Next, the home door control system 1 checks whether the train 10 has entered the platform 50 of the station and stopped at a fixed position (step S2). This check is performed by the ground wireless communication unit 73 of the home door control device 70 based on the detection result of the fixed position stop detection unit 81.

[0030] And when it is confirmed that the train 10 has stopped at a fixed position (step S2; YES), the home door control system 1 performs interlocking control of the vehicle door 11 of the train 10 and the home door 51 installed on the platform 50 (step S3). The interlocking control of the vehicle door 11 of the train 10 and the home door 51 installed on the platform 50 is performed, for example, as follows.

[0031] First, the ground wireless communication unit 73 of the home door control device 70 that has confirmed in step S2 that the train 10 has stopped at a fixed position wirelessly transmits a fixed position stop confirmation signal to the on-vehicle wireless communication unit 33 of the on-vehicle device 30. When the on-vehicle wireless communication unit 33 receives the fixed position stop confirmation signal from the ground wireless communication unit 73, it notifies the crew or the like that the train 10 has stopped at a fixed position via the notification unit 37. The crew or the like who has received the notification operates the conductor's door switch 41 to open the vehicle door 11 on the platform 50 side of the train 10, and the conductor's door switch 41 outputs an opening operation signal corresponding to the operation of the crew or the like to the on-vehicle wireless communication unit 33.

[0032] When a door opening operation signal is input from the conductor's door switch 41, the on-vehicle wireless communication unit 33 gives a vehicle door opening command corresponding to the input door opening operation signal to the vehicle door control unit 35 and wirelessly transmits a home door opening command corresponding to the vehicle door opening command to the ground wireless communication unit 73 of the home door control device 70. Here, the home door opening command wirelessly transmitted, that is, the home door opening command wirelessly transmitted to the ground wireless communication unit 73 of the home door control device 70 on the condition that the train 10 has stopped at a fixed position, is a normal home door opening command.

[0033] The vehicle door control unit 35 given the vehicle door opening command opens each vehicle door 11 on the home 50 side of the train 10. Further, the ground wireless communication unit 73 that has received the home door opening command gives the received home door opening command to the home door control unit 75, and the home door control unit 75 given the home door opening command opens a plurality of home doors 51 corresponding to each vehicle door 11 to be opened among the plurality of home doors 51 installed at the home 50. Note that giving the received home door opening command to the home door control unit 75 includes converting the received home door opening command for use by the home door control unit 75 and giving it to the home door control unit 75.

[0034] That is, normally, the on-vehicle wireless communication unit 33 gives a vehicle door opening command to the vehicle door control unit 35 on the condition that the fixed position stop confirmation signal has been received from the ground wireless communication unit 73, and wirelessly transmits a (normal) home door opening command to the ground wireless communication unit 73. In other words, the vehicle door 11 and the home door 51 can be opened on the condition that the train 10 has stopped at a fixed position.

[0035] Also, when the conductor operates the conductor's door switch 41 to close each vehicle door 11 that is open when the train 10 departs from the station, the conductor's door switch 41 outputs a closing operation signal corresponding to the operation of the crew or the like to the on-vehicle wireless communication unit 33. When a closing operation signal is input from the conductor's door switch 41, the on-vehicle wireless communication unit 33 gives a vehicle door closing command to the vehicle door control unit 35 and transmits a home door closing command to the ground wireless communication unit 73 of the home door control device 70.

[0036] The vehicle door control unit 35 to which the vehicle door closing command is given closes the vehicle doors 11 of the train 10 that are open (each vehicle door 11 on the platform 50 side). Also, the ground wireless communication unit 73 that has received the platform door closing command gives the received platform door closing command to the platform door control unit 75, and the platform door control unit 75 to which the platform door closing command is given closes the open platform door 51. Note that giving the received platform door closing command to the platform door control unit 75 includes converting the received platform door closing command for use by the platform door control unit 75 and giving it to the platform door control unit 75.

[0037] After that, when the train 10 that has left the station goes outside the predetermined range, the platform door control system 1 releases the wireless communication between the on-vehicle wireless communication unit 33 of the on-vehicle device 30 and the ground wireless communication unit 73 of the platform door control device 70 that has been established (step S4).

[0038] Figures 4 and 5 show operation examples of the platform door control system 1 when an emergency occurs in the passenger compartment of the train 10.

[0039] Figure 4 is a flowchart showing an operation example of the on-vehicle wireless communication unit 33 of the on-vehicle device 30 when an emergency occurs in the passenger compartment of the train 10. This flowchart starts when the emergency reporting device 43 is operated by a passenger of the train 10, in other words, when the on-vehicle wireless communication unit 33 inputs an SOS signal from the emergency reporting device 43.

[0040] In step S11, the on-vehicle wireless communication unit 33 that has input an SOS signal from the emergency reporting device 43 gives an emergency notification command to the notification unit 37, and notifies the crew and others that an emergency has occurred in the passenger compartment of the train 10 via the notification unit 37. By this notification, the crew and others will grasp that an emergency has occurred in the passenger compartment of the train 10 and will appropriately stop the train 10. Note that after stopping the train 10, the crew and others can also operate the conductor's door switch 41 as necessary to open some or all of the plurality of vehicle doors 11 of the train 10.

[0041] In step S12, the on-vehicle wireless communication unit 33 checks whether a door cock operation signal is input from the emergency door cock 45. When a door cock operation signal is input from the emergency door cock 45, that is, when the emergency door cock 45 is operated by a passenger of the train 10 (step S12; YES), the on-vehicle wireless communication unit 33 proceeds to the process of step S15. On the other hand, when no door cock operation signal is input from the emergency door cock 45 (step S12; NO), that is, when the emergency door cock 45 is not operated by a passenger, the on-vehicle wireless communication unit 33 proceeds to the process of step S13. As described above, when the emergency door cock 45 is operated, the passengers of the train 10 can manually open the vehicle door 11 of the train 10.

[0042] In step S13, the on-vehicle wireless communication unit 33 checks whether an opening operation signal is input from the conductor's door switch 41. When no opening operation signal is input from the conductor's door switch 41 (step S13; NO), that is, when a conductor or the like does not operate the conductor's door switch 41 to open the vehicle door 11 of the train 10, the on-vehicle wireless communication unit 33 returns to the process of step S12. On the other hand, when an opening operation signal is input from the conductor's door switch 41 (step S13; YES), that is, when a conductor or the like operates the conductor's door switch 41 to open the vehicle door 11 of the train 10, the on-vehicle wireless communication unit 33 proceeds to the process of step S14.

[0043] In step S14, the on-vehicle wireless communication unit 33 gives a vehicle door opening command to the vehicle door control unit 35 in order to open some or all of the plurality of vehicle doors 11 of the train 10.

[0044] In step S15, the on-vehicle wireless communication unit 33 checks whether wireless communication has been established between itself (i.e., the on-vehicle wireless communication unit 33) and the ground wireless communication unit 73 of the home door control device 70. If wireless communication has been established between itself (the on-vehicle wireless communication unit 33) and the ground wireless communication unit 73 of the home door control device 70, that is, if wireless communication between the on-vehicle device 30 and the home door control device 70 is possible, the on-vehicle wireless communication unit 33 proceeds to the process of step S16. On the other hand, if wireless communication between itself (the on-vehicle wireless communication unit 33) and the ground wireless communication unit 73 has not been established, that is, if wireless communication between the on-vehicle device 30 and the home door control device 70 is not possible, the on-vehicle wireless communication unit 33 ends this flow.

[0045] In step S16, the on-vehicle wireless communication unit 33 transmits an emergency home door opening command to the ground wireless communication unit 73 of the home door control device 70. That is, when emergency processing is performed inside the train 10, the on-vehicle wireless communication unit 33 transmits a home door opening command to the ground wireless communication unit 73 even if it has not received the fixed-position stop confirmation signal from the ground wireless communication unit 73 (even if the train 10 is not stopped at a fixed position). Here, the emergency processing includes the operation of the emergency reporting device 43, the operation of the emergency door cock 45, and / or the operation of the conductor's door switch 41 to open the vehicle door 11.

[0046] In step S17, the on-vehicle wireless communication unit 33 determines whether it has received an answer back from the ground wireless communication unit 73 of the home door control device 70 for the emergency home door opening command transmitted in step S16. If the answer back has been received, the on-vehicle wireless communication unit 33 ends this flow. On the other hand, if the answer back has not been received, the on-vehicle wireless communication unit 33 proceeds to the process of step S18. Note that the answer back includes a home door opened signal indicating that a plurality of home doors 51 installed in the home 50 have been opened, as will be described later.

[0047] In step S18, the on-vehicle wireless communication unit 33 determines whether or not a predetermined time has elapsed since it transmitted an emergency home door opening command to the ground wireless communication unit 73 of the home door control device 70. If the predetermined time has not elapsed, the on-vehicle wireless communication unit 33 returns to step S16 and wirelessly transmits the emergency home door opening command to the ground wireless communication unit 73 again. If the predetermined time has elapsed, the on-vehicle wireless communication unit 33 proceeds to the process of step S19.

[0048] In step S19, the on-vehicle wireless communication unit 33 gives a notification command to the notification unit 37, and via the notification unit 37, notifies the crew or the like that an answerback for the emergency home door opening command has not been received, that is, that the answerback has not been received. By this notification, the crew or the like can use the in-vehicle broadcast device 47, the in-vehicle information display device 49, etc. to inform the passengers that there is a possibility that the home door 51 has not been opened in order to prompt the passengers evacuating from the passenger compartment of the train 10 to the platform 50 to pay attention.

[0049] FIG. 5 is a flowchart showing an example of the operation of the ground wireless communication unit 73 of the home door control device 70. This flowchart is repeatedly executed, for example, every predetermined time.

[0050] In step S21, the ground wireless communication unit 73 determines whether or not it has received an emergency home door opening command from the on-vehicle wireless communication unit 33 of the on-vehicle device 30. If it has received the emergency home door opening command, the ground wireless communication unit 73 proceeds to the process of step S22. If it has not received the emergency home door opening command, the ground wireless communication unit 73 ends this flow.

[0051] In step S22, the ground wireless communication unit 73 gives an alarm command to the alarm unit 77, and issues an alarm via the alarm unit 77. This alarm mainly notifies the user in the home 50 and the station staff at the station that the home door 51 is opened at a timing different from the normal timing. By this alarm, it is possible to prompt the user in the home 50 to pay attention and / or prompt the station staff at the station to take actions for ensuring the safety of the user in the home 50.

[0052] In step S23, the ground wireless communication unit 73 gives the emergency home door opening command received in step S21 to the home door control unit 75, thereby opening all of the plurality of home doors 51 installed in the home 50. Note that giving the received emergency home door closing command to the home door control unit 75 includes converting the received emergency home door closing command for use by the home door control unit 75 and giving it to the home door control unit 75.

[0053] In step S24, the ground wireless communication unit 73 transmits a home door opened signal indicating that the plurality of home doors 51 installed in the home 50 have been opened to the on-vehicle wireless communication unit 33 as an answerback to the emergency home door opening command received in step S21.

[0054] As described above, the home door control system 1 according to the embodiment includes an on-vehicle device 30 mounted on the train 10 and a home door control device 70 installed on the platform of the station. The on-vehicle device 30 is configured to wirelessly transmit a home door opening command when an emergency process is performed inside the train 10. The home door control device 70 is configured to open a plurality of home doors 51 installed on the platform 50 when receiving a home door opening command from the on-vehicle device 30. Here, the emergency process includes that a passenger of the train 10 operates the emergency reporting device 43 (operation of the emergency reporting device 43), that a passenger of the train 10 operates the emergency door cock 45 (operation of the emergency door cock 45), and that a conductor or the like operates the conductor's door switch 41 to open the vehicle door 11 of the train 10 based on an SOS signal from the emergency reporting device 43 (opening operation of the vehicle door 11 of the train 10), etc.

[0055] Specifically, in the home door control system 1, the on-vehicle device 30 (the on-vehicle wireless communication unit 33 thereof) inputs an SOS signal from the emergency reporting device 43, inputs a door cock operation signal from the emergency door cock 45 or an opening operation signal from the conductor's door switch 41, and when wireless communication is established with the home door control device 70 (the ground wireless communication unit 73 thereof), regardless of whether the train 10 is stopped at a fixed position of the station, it wirelessly transmits an emergency home door opening command to the home door control device 70 (the ground wireless communication unit 73 thereof) (see FIG. 4). Further, when the home door control device 70 receives an emergency home door opening command wirelessly transmitted from the on-vehicle device 30, regardless of whether the train 10 is stopped at a fixed position of the station, it opens all of the plurality of home doors 51 installed on the platform 50 (see FIG. 5).

[0056] That is, in the home door control system 1 according to the embodiment, even when an emergency occurs inside the train 10 and the train 10 stops before reaching the fixed position, all of the plurality of home doors 51 installed on the home 50 are opened. Therefore, an evacuation route for the passengers of the train 10 can be secured on the home 50. Thus, according to the home door control system 1 according to the embodiment, it is possible to prevent the home door 51 from obstructing the evacuation of the passengers of the train 10 when an emergency occurs, that is, to prevent any hindrance to the evacuation of the passengers of the train 10.

[0057] In addition, when the home door control device 70 (the ground wireless communication unit 73 thereof) opens all of the plurality of home doors 51 based on the emergency home door opening command from the on-vehicle device 30 (the on-vehicle wireless communication unit 33 thereof), it is configured to issue an alarm to the users and station staff on the home 50 via the alarm unit 77. Therefore, it is possible to notify the users and station staff on the home 50 that the home door 51 is opened at a timing different from normal, thereby prompting the users on the home 50 to pay attention and / or prompting the station staff to take actions to ensure the safety of the users on the home 50.

[0058] Furthermore, when the home door control device 70 (the ground wireless communication unit 73 thereof) opens the plurality of home doors 51 based on the emergency home door opening command from the on-vehicle device 30 (the on-vehicle wireless communication unit 33 thereof), it is configured to wirelessly transmit an answerback including a home door opened signal to the on-vehicle device 30 (the on-vehicle wireless communication unit 33 thereof). The on-vehicle device 30 (the on-vehicle wireless communication unit 33 thereof) is configured to wirelessly transmit the emergency home door opening command again when it does not receive the answerback from the home door control device 70 (the ground wireless communication unit 73 thereof). Therefore, it is possible to enhance the certainty of the opening of the home door 51 in the event of an emergency, that is, the certainty of securing the evacuation route for the passengers of the train 10.
