[0009] [First embodiment] Hereinafter, a platform fence device, which is a platform safety system according to a first embodiment, will be described with reference to the drawings.

[0010] 1(A) and 1(B) are a plan view and a front view, respectively, that show a station platform PF and a platform fence device 100. Fig. 2 shows two platform fence elements 101 that constitute the platform fence device 100 as seen from the platform PF side, with the exterior panel on the platform PF side of the platform fence elements 101 removed.

[0011] A platform fence device 100 is installed on the platform PF along the edge portion Pe of the platform PF. The platform fence device 100 includes a number of platform fence elements 101 as basic equipment elements DE, as well as end portions 100a and 100b, and a remote terminal device 102. A group of platform fence elements 101 or equipment elements DE are installed along the platform PF of a station and operate in conjunction with each other. The end portions 100a and 100b may be extensions of the platform fence elements 101 at both ends that have been given the function. The terminal device 102 communicates with each platform fence element 101 via a communication network NT and can grasp or monitor the operating status of each platform fence element 101.

[0012] In the state shown in FIG. 1(A) and 1(B), in each platform fence element 101, the door body 20 comes out of the end opening of the platform fence main body 30 and the door body 20 closes the boarding and alighting passage, and the platform fence device 100 forms a platform fence that extends along the edge of the platform PF as a whole. One of the many platform fence elements 101 (the rightmost in the drawing) is a parent unit P, and the remaining platform fence elements 101 of the many platform fence elements 101 excluding the parent unit P are child units C. However, as will be described in detail later, even the child unit C can operate autonomously, and can switch from child unit mode to parent unit mode so as to perform the same function as the parent unit P. The parent unit P collects operation information OI regarding the state of the many platform fence elements 101 that constitute the platform fence device 100, that is, the device elements DE. In this way, by determining a representative parent unit P and managing them, it becomes easier to manage the operation status of the multiple platform fence elements 101, that is, the device elements DE. In addition, by making it possible to replace the master unit P, it is possible to avoid the inconvenience of the entire platform fence device 100 becoming inoperable due to a failure of a master unit such as a specific platform fence element 101 or a general control panel.

[0013] 2, the door body 20 is a door member that is housed within the platform fence main body 30 and is provided so as to be freely inserted and removed. The door body 20 has a main door body 21 that moves laterally forward and backward from a first end 32 that is one end of the platform fence main body 30, and a secondary door body 22 that moves laterally forward and backward from a second end 33 that is the other end of the platform fence main body 30. Normally, the operations of the main door body 21 and the secondary door body 22 are controlled in conjunction with each other.

[0014] The platform fence main body 30 is a main body device 3 fixed to the floor of the platform PF, and has a door pocket structure that holds the door body 20 so that it can move forward and backward. The platform fence main body 30 has an electric circuit system 40, a guide mechanism 50, and a transmission mechanism 60.

[0015] 3, the electric circuit system 40 has a control device 41, a power supply device 42, an individual operation panel 43, a motor 44, a communication device 45, a sensor 46, an emergency open button 47, an indicator light 48, and a speaker 49. The electric circuit system 40 is a component used for controlling and driving the platform fence element 101. The control device 41, the power supply device 42, the individual operation panel 43, the motor 44, etc. are disposed and fixed on a substrate (not shown).

[0016] The control device 41 autonomously judges and controls the operation of the internal mechanisms, i.e., the power supply device 42, the individual operation panel 43, the motor 44, the communication device 45, the sensor 46, the emergency open button 47, the indicator lamp 48, the speaker 49, etc., and transmits and receives digital information DI from other platform fence elements 101 via a communication line CC (see FIG. 2) connected to each other, for example, by a wired LAN (local area connection), and acquires link information CI as part of the digital information DI. The communication line CC shown in FIG. 2 includes a cable and a repeater and connects multiple control devices 41 to each other so that they can communicate with each other, and may be, for example, something like a LAN (Local Area Network). The control device 41 has a control circuit 41a and a drive circuit 41b. The control circuit 41a is a computer and controls the operating state of the door body 20. The drive circuit 41b applies drive force to the motor 44 while checking the position of the door body 20.

[0017] The power supply device 42 is a device that receives an AC power supply such as a commercial power supply as an input, and includes a DC power supply circuit, etc. The power supply device 42 supplies power to each component such as the control device 41.

[0018] The individual operation panel 43 accepts individual opening and closing operations performed on the door body 20 by a train crew member, station staff, etc. This allows the door body 20 to be manually operated separately from the coordinated or interlocking operation of the platform fence device 100. Although not shown in the figure, the individual operation panel 43 can be exposed by opening an opening and closing cover provided on an exterior panel on the platform PF side. This allows station staff, etc. to manually operate the individual operation panel 43.

[0019] The motor 44 generates a driving force for moving the door body 20. The motor 44 has a first motor 44a that drives the main door body 21 and a second motor 44b that drives the secondary door body 22 (see FIG. 2).

[0020] The communication device 45 is connected to other platform fence elements 101 constituting the platform fence device 100 via a communication line CC shown in Fig. 1. The communication device 45 enables the control device 41, i.e., the platform fence element 101 of interest, to communicate with the other platform fence elements 101 constituting the platform fence device 100.

[0021] With reference to FIG. 2 etc., when the platform fence element 101 of interest is the parent unit P, the parent unit P or the control device 41 incorporated therein transmits and receives digital information DI or linkage information CI to a group of child units C which are other platform fence elements 101, and remotely manages the autonomous operations of the group of child units C while realizing a linked operation of the entire platform fence device 100 or a unified operation of the entire platform fence device 100. Specifically, the control device 41 of the parent unit P can output an operation command to each of the platform fence elements 101 constituting the group of child units C by communicating with the control device 41 provided in each of the platform fence elements 101 constituting the group of child units C, and can receive operation status data from each of the platform fence elements 101 constituting each child unit C. As a result, the control device 41 of the parent unit P can collectively monitor the operation status of the platform fence elements 101 including itself, including the viewpoint of occurrence of an abnormality.

[0022] The parent machine P communicates with the terminal device 102 via the communication line CC and the communication network NT. The terminal device 102 is a computer used by a system administrator, and can function as an information presentation device DP that receives operation information OI collected by the parent machine and presents the operation status or operation information OI of each platform fence element 101 to the system administrator. The communication network NT is, for example, a local area network (LAN), but is not limited to this and may be a wide area network (WAN), the Internet, or a combination of these. The communication network NT may also include a public switched telephone network (PSTN), an integrated services digital network (ISDN), etc.

[0023] The sensor 46 is a measuring device 4 that measures an object present around the platform fence element 101. The sensor 46 is an optical sensor, specifically, for example, a two-dimensional scanner, a three-dimensional scanner, or the like. The sensor 46 can measure whether a train TR or a vehicle TRc is present on the track RL corresponding to the platform fence element 101, whether an obstacle exists between the platform fence element 101 and the entered train TR or vehicle TRc, and whether the vehicle-side door TRd of the vehicle TRc is open or not, and can also determine whether the train TR is stopped at a fixed position. As shown in FIG. 1, the sensor 46 has a detection area DR that spreads in a fan shape over a predetermined range from the door body 20 to the track RL side. The detection area DR of the sensor 46 includes the upper part of the track RL, etc., so that it is possible to measure the distance to a running or stopped train TR. The data obtained by the sensor 46 is output to the control device 41, and is appropriately processed to determine whether there is an obstacle or the like. In this case, additional information such as whether the train TR is on the line or not and whether the vehicle side door TRd is open or not can be obtained by a measuring device 4, i.e., an obstacle detection device, which measures whether or not there is an obstacle between the platform fence element 101 and the train TR, and such additional information can be used to make decisions when each platform fence element 101, i.e., each equipment element DE, operates autonomously.

[0024] 3, the emergency open button 47 is a button for opening the door body 20 from the track RL side or the train side in the event of an emergency. The on / off state of the emergency open button 47 is read by the control device 41.

[0025] The indicator light 48 operates under the control of the control device 41 and indicates the open / closed state of the door body 20. For example, the indicator light 48 lights up when the door body 20 is open and goes out when the door body 20 is closed. The indicator light 48 also lights up or flashes when an abnormality occurs in the platform fence device 100.

[0026] 2, the guide mechanism 50 is composed of mechanical parts including rollers, adjustment jigs, etc. (not shown) in addition to the guide rail 51. The guide rail 51 is disposed so as to sandwich the top and bottom of the door body 20. The guide mechanism 50 enables the door body 20 to move laterally smoothly, that is, to open and close the door body 20.

[0027] The transmission mechanism 60 is composed of mechanical parts including a belt 61, a pulley 62, and a connector (not shown). The transmission mechanism 60 transmits the driving force of the motor 44 to the door body 20. Specifically, the transmission mechanism 60 and the motor 44 are provided corresponding to the main door body 21 and the secondary door body 22, respectively. As a result, the driving force of the first motor 44a is transmitted to the main door body 21, and the driving force of the second motor 44b is transmitted to the secondary door body 22.

[0028] 1, one end 100a of the platform fence device 100 corresponds to the front end of the leading car TRc of the train TR, i.e., the first end E1, and the other end 100b of the platform fence device 100 corresponds to the rear end of the last car TRc of the train TR, i.e., the second end E2. The ends 100a and 100b are equipped with, for example, a wireless communication device 81 and a wired communication device 82 as auxiliary devices.

[0029] The wireless communication device 81 enables wireless communication with a running or stopped train TR. The wireless communication device 81 enables, for example, medium-range wireless communication, but is not limited thereto and may enable short-range inductive wireless communication.

[0030] The wired communication device 82 is connected to each of the platform fence elements 101 constituting the platform fence device 100 via a communication line CC shown in Fig. 1. The wired communication device 82 is communicatively connected to the platform fence elements 101, particularly the master unit P, thereby enabling the train TR to grasp the open / closed state of the platform fence device 100 and for the platform fence device 100 to operate in cooperation with the train TR.

[0031] At the rearmost end 100b, a monitoring panel 85, which is an operation panel, is provided on the platform PF side. The monitoring panel 85 is for checking the status of the platform fence device 100 and for manually operating the platform fence device 100, and is also an information display device DP for staff members that displays the operating status or operating information OI of each platform fence element 101. The monitoring panel 85 is equipped with an indicator ID that displays the open / closed state of the entire platform fence device 100, and an open / close button BT that instructs the opening and closing of the entire platform fence device 100. The indicator ID functions as an indicator light DL that displays the fully closed state of the multiple platform fence elements. The monitoring panel 85 is communicatively connected to the platform fence elements 101, particularly the parent unit P, via a communication line CC, and enables crew members and station staff to monitor and operate the status of the platform fence device 100.

[0032] FIG. 4 is a conceptual diagram for explaining the control circuit 41a incorporated in the control device 41 shown in FIG. 1 and the like. The control circuit 41a is a computer, and has an arithmetic processing unit 48a, a storage unit 48b, and the like. The arithmetic processing unit 48a operates based on a program stored in the storage unit 48b. The storage unit 48b stores a parent operation program PG1 that operates the control circuit 41a in parent mode. The arithmetic processing unit 48a operates based on the parent operation program PG1, so that the platform fence element 101 functions as a parent unit P. The storage unit 48b stores a child operation program PG2 that operates the control circuit 41a in child mode. The arithmetic processing unit 48a operates based on the child operation program PG2, so that the platform fence element 101 functions as a child unit C. The control circuit 41a of the control device 41 stores a monitoring program PG3 that monitors the operating status of all other platform fence elements 101 other than itself, whether it operates in parent mode or child mode. That is, all the device elements DE, which are all the platform fence elements 101, have a function of mutually monitoring the operating state. When the control circuit 41a detects that the parent unit P has failed while operating in the child unit mode, if the control circuit 41a has the next priority among the operating device elements DE, it switches the operation to operate its own platform fence element 101 in the parent unit mode. As a result, a new parent unit P is selected from the child units C. In other words, even if the original parent unit P fails, a new parent unit P is selected from the remaining platform fence elements 101, and the new parent unit P becomes the representative, and information from multiple other device elements DE, that is, multiple other platform fence elements 101, is collected in the new parent unit P, and the operating state of the platform fence device 100 is secured. However, the original parent unit P that has failed can be temporarily placed in a constantly open state by an attendant pressing the emergency open button 47.

[0033] FIG. 5 is a conceptual diagram illustrating the terminal device 102. The terminal device 102 is a computer that operates under the management of a system administrator, and manages the operating status of the platform fence device 100. The terminal device 102 has a main control device 102a, a storage device 102b, a user interface device 102c, and a communication device 102d. The terminal device 102 communicates with a master unit P, which is one of the multiple platform fence elements 101 that make up the platform fence device 100, via the communication network NT shown in FIG. 1, using the communication device 102d. A program that operates the terminal device 102 is stored in the storage device 82.

[0034] FIG. 6 is a conceptual diagram for explaining the operation of a specific platform fence element 101. In this case, the platform fence element 101, that is, the control circuit 41a of the control device 41 is assumed to be operating in the child mode (step S01). In this case, the platform fence element 101, as a child unit C, performs an autonomous opening and closing operation based on a command signal from a separately existing parent unit P. The control circuit 41a of the child unit C periodically checks whether the parent unit P has broken down (step S02), and when it detects that the parent unit P has broken down, it checks its own priority (step S03). When its own priority is next, that is, when it has the highest priority to become the parent unit P among the remaining child units C, the control circuit 41a switches the operation of the platform fence element 101 to operate in the parent mode (step S04). The control circuit 41a of the platform fence element 101 that has become the parent unit P accepts an instruction by operating the monitoring panel 85, transmits an operation command to the child unit C, and checks the operation of the child unit C and its own operation status. At this time, the control circuit 41a in the new parent unit P performs a failure check on the child units C, etc. Here, the child unit C may perform a self-diagnosis for the failure check, but for example, when the parent unit P communicates with the child unit C and there is no response, the child unit C may be diagnosed as having a failure.

[0035] For example, when the parent unit P transmits a command signal for an opening / closing operation to the child unit C, the child unit C operates in principle to follow the command signal, but prioritizes a situation that the child unit C judges independently. Specifically, the child unit C waits until its own sensor 46 detects that the vehicle side door TRd is open, and then opens the door body 20. Conversely, the child unit C waits until its own sensor 46 confirms that the vehicle side door TRd is closed and that no obstacle is present, and then closes the door body 20.

[0036] In the above explanation, the monitoring panel 85 is required, but the monitoring panel 85 can be omitted, and the individual operation panel 43 provided on the platform fence element 101, which is the parent unit P, can be used as a monitoring panel for an attendant to monitor and operate the status of the platform fence element 101.

[0037] In the above explanation, the master unit P operates in principle in response to the operation of the open / close button BT provided on the monitoring panel 85, and the slave unit C is linked to the master unit P in principle, but the distinction between the master unit P and the slave unit C may be eliminated with respect to the opening and closing operations, and each platform fence element 101 may perform the opening and closing operations independently and autonomously. In this case, the open / close button BT will no longer exist on the monitoring panel 85. Each platform fence element 101 detects the vehicle TRc by the sensor 46 provided on each platform fence element 101, and can further detect that the vehicle side door TRd has switched from a closed state to an open state, so that each platform fence element 101 opens the door body 20 when the sensor 46 detects the opening of the vehicle side door TRd. On the other hand, the sensor 46 provided on each platform fence element 101 can detect that the vehicle side door TRd has been switched from an open state to a closed state, and can determine whether or not there is an obstacle between the train TR or the vehicle TRc. Therefore, each platform fence element 101 closes the door body 20 when the sensor 46 detects the closing of the vehicle side door TRd and determines that there is no obstacle such as a person staying behind. In this case, the platform fence element 101 performs the opening and closing operation completely autonomously, and opens and closes the door body 20 in synchronization with the opening and closing of the vehicle side door TRd, but each platform fence element 101 can obtain cooperation information CI between them. By obtaining the cooperation information CI, each platform fence element 101 can determine whether or not the platform fence device 100 as a whole has been opened or closed. The open / closed state of each platform fence element 101 and the detection information by the sensor 46 can be displayed on the indicator ID of the monitoring panel 85 as the operation state of each platform fence element 101, for example, by information provided from each platform fence element 101.

[0038] Even when the slave unit C is not actively linked to the master unit P as in the above modified example, the master unit P can be selected to manage the management information. The master unit P, which manages the management information, collects information from the other slave units C and acquires various information as linked information CI, including operation information OI, such as the start or completion of the opening / closing operation of the master unit P and the slave units C, the presence or absence of a malfunction, and information detected by the sensor 46. The master unit P can display such linked information CI on the indicator ID of the monitoring panel 85 and can provide information to the terminal device 102, making it possible to manage the overall operating status of the platform fence device 100 with the master unit P at the center.

[0039] As described above, the platform safety system of the first embodiment, i.e., the platform fence device 100, comprises a plurality of equipment elements DE (i.e., a plurality of platform fence elements 101) that are installed along the station platform PF and operate in conjunction with each other, and each equipment element DE has a control device 41 that makes autonomous decisions to control the operation of its internal mechanism and acquires coordination information CI from the other equipment elements DE.

[0040] In the above-mentioned platform fence device 100, each equipment element DE autonomously judges and controls the operation of its internal mechanism, and also has a control device 41 that acquires coordination information CI from the other equipment elements DE, so there is no need to install a comprehensive control panel, the installation costs of the comprehensive control panel can be reduced, and there is no need to consider reserving space for the comprehensive control panel.

[0041] Second Embodiment Hereinafter, a platform monitoring system, which is a platform safety system according to the second embodiment, will be described with reference to the drawings. The platform monitoring system 200 of the present embodiment is a system for monitoring the edge portion Pe of the platform PF and the tracks.

[0042] As shown in FIG. 7, the home monitoring system 200 includes a number of equipment elements DE and an information display device 285 that displays the measurement results of the equipment elements DE. The equipment elements DE are monitoring devices 201, and the information display device 285 displays the operation information OI collected by the monitoring devices 201. One of the many monitoring devices 201 is a master unit P, and the remaining monitoring devices 201, excluding the master unit P, are slave units C. However, as will be described in detail later, even the slave unit C can switch its operation from a slave unit mode to a master unit mode so that it can perform the same functions as the master unit P. In this way, by determining a representative master unit P and performing management, it becomes easy to collectively manage the operation statuses of the multiple monitoring devices 201, that is, the multiple equipment elements DE.

[0043] The monitoring device 201 includes an imaging unit 91 including a camera, and a drive control unit 92 that performs image processing on a video signal obtained by the imaging unit 91 to determine whether or not a dangerous state or a sign thereof has occurred in the home PF. Each monitoring device 201 monitors an object in its respective detection area DR. The monitoring results by each monitoring device 201 are displayed, for example, on the display of the information presentation device 285 as an image with emphasis processing and annotations added.

[0044] 8 is a conceptual diagram illustrating the drive control unit 92. The drive control unit 92 is a computer, and includes a control device 92a, a storage device 92b, and a communication device 92d. The drive control unit 92 is capable of communicating with another monitoring device 201 via the communication device 92d. The control device 92a autonomously determines and controls the operation of the imaging unit 91, which is an internal mechanism, and also acquires digital information DI or linkage information CI from another monitoring device 201, which is another device element DE.

[0045] The control device 92a includes an image processing unit 92i, and can extract the presence of a moving object and its moving speed from the image obtained by the imaging unit 91 by using optical flow and contour extraction, and can extract, for example, the position of a pedestrian on the platform PF, and determine whether or not a pedestrian is in a dangerous position.

[0046] When the monitoring device 201 is a parent device P, it integrates its own monitoring results with the monitoring results obtained by other monitoring devices 201 that are child devices C, and transmits the integrated monitoring results to the information presentation device 285 and the terminal device 102. The child device C periodically checks whether the parent device P has broken down, and when it detects that the parent device P has broken down, if its own priority is next, that is, if its priority to become the parent device P is the highest among the remaining child devices C, it switches its operation to operate in parent device mode.

[0047] The above-mentioned platform monitoring system 200 includes a plurality of equipment elements DE (i.e., a plurality of monitoring devices 201) that are installed along the station platform PF and operate in coordination with each other, and each equipment element DE has a control device 92a that autonomously makes decisions to control the operation of its internal mechanism and acquires coordination information CI from the other equipment elements DE.

[0048] In the above-mentioned home monitoring system 200, each equipment element DE autonomously judges and controls the operation of its internal mechanism, and has a control device 92a that acquires coordination information CI from the other equipment elements DE. Therefore, there is no need to install a general control panel in the home monitoring system 200, the installation costs of the general control panel can be reduced, and there is no need to consider reserving space for the general control panel.

[0049] In the above-described platform monitoring system 200, the master unit P is not essential, and the slave units C can also individually transmit monitoring results to the information presentation device 285. Even in this case, by sharing information between device elements DE, it is possible to perform processing such as tracking the behavior of a specific pedestrian beyond the individual detection areas DR.

[0050] 〔others〕 The present invention is not limited to the above-described embodiment, and can be embodied in various forms without departing from the spirit and scope of the present invention.
