DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a platform door system provided on a platform of a station and having a plurality of home door devices which are opened and closed in synchronization with a door of a railway vehicle.

[0002]

2. Description of the Related Art When a railway vehicle arrives at a platform and stops at the platform, a door panel of a home door device provided at a position corresponding to a door of each vehicle is opened by operation of a vehicle crew, Thereafter, the vehicle door is opened. At this time, an individual control panel provided in each home door device for controlling each home door device outputs an open confirmation signal to a home control panel that supervises each individual control panel. When the home control panel receives the open confirmation signal from all the individual control panels, it outputs an all home door open confirmation signal to the vehicle. When confirming the all-home door open confirmation signal, the vehicle crew determines that all the door panels have been opened and opens the vehicle door.

[0003] On the other hand, when a vehicle departs from a platform, the home door is closed after the vehicle crew closes the vehicle door. At this time, the home control panel transmits an all-home door closing confirmation signal to the vehicle based on the closing confirmation signal from all the individual control panels. When the crew of the vehicle confirms the all-home-door-close confirmation signal, it determines that all the door panels have been closed and starts the vehicle.

When an attempt is made to open the door panel of each home door device, if one door panel does not open normally, a vehicle door for an unopened door panel is opened, which is dangerous to passengers. is there. Therefore, the crew cannot open the vehicle door until it is confirmed that all the door panels are open, or until it is determined that the safety of passengers is secured even if all the door panels are not open. Similarly,
If a door panel of a home door device is not closed normally when the door panel of the home door device is closed, it is dangerous for passengers to leave the vehicle with the door panel of the home door device open. . Therefore, the crew departs the vehicle until it is possible to confirm that the door panels of all the home door devices are closed, or until it is confirmed that all the door panels are not closed but the safety of passengers is secured. Can not do.

When the door panel of the home door device cannot be normally opened and closed, the individual control panel of the home door device outputs an abnormal signal to the home control panel. A display device for displaying information based on the abnormal signal is provided in the station office. The display device displays information indicating that an abnormality has occurred and the home door device in which the abnormality has occurred. The station staff who confirms the display immediately rushes to the home door device where the abnormality has occurred, quickly grasps the details of the abnormality, and if the vehicle is not restored promptly, the train operation schedule is disrupted.

[0006]

When an abnormality occurs in the home door device, a station worker who rushes to the home door device quickly grasps the details of the abnormality and determines whether or not the abnormality can be recovered by immediate maintenance. Must be done on the spot. However, it was difficult to make such a decision promptly, requiring the work of station staff and delaying restoration.

[0007] It is an object of the present invention to provide a platform door system capable of promptly determining a countermeasure when an abnormality occurs in a home door device.

[0008]

In the platform door system according to the present invention, a plurality of home door devices are installed on the platform. An individual control panel for individually controlling the opening and closing of each of the home door devices is provided corresponding to each of the home door devices. A home control panel communicates with each individual control panel, and the home control panel outputs an open or close signal for opening and closing the home door device to each individual control panel. A display device is connected to the home control panel, and the display device displays information based on signals obtained by mutual communication between the individual control panel and the home control panel. The individual control panel has an abnormality detection unit that detects an abnormality of the home door device in conjunction with the opening / closing control of the home door device and outputs an abnormality signal to the home control panel. As the abnormality of the home door device, various types can be considered.
The display device can be disposed, for example, in a station office at a station, and when the home control panel receives the abnormal signal, based on the abnormal signal, information indicating the home door device that has caused the abnormality. And the content information of the abnormality. The information indicating the home door device in which the abnormality has occurred can be generated separately from the abnormality signal.

[0009] When an abnormality occurs in the home door device, for example, information indicating the home door device in which the abnormality has occurred and the content of the abnormality are displayed on a display device in the station office. The station staff can know the contents of the abnormality by checking the display on the display device, without having to go to the installation location of the home door device and directly check. Therefore, after preparing for the treatment for the abnormality in the station office or the like in advance, it is possible to go to the installation location of the home door device in which the abnormality has occurred. Thus, early recovery of the system can be achieved.

[0010] The individual control panel invalidates the open or close signal from the home control panel, and forcibly outputs an output signal to be output to the home control panel if the home door device opens and closes normally. And a second state in which the open or close signal of the home door device can be output by the manual opening / closing means in the first state.
And setting means for setting the state to the above state.
The first state and the second state can be set by one setting means, and the setting means can be provided for each of the first state and the second state.

The station staff who rushes to the home door device where the abnormality has occurred operates the setting means of the individual control panel to set the first or second state according to the content of the abnormality. In the first state, since the open or close signal from the home control panel is invalidated, the abnormal home door device does not open or close according to the instruction from the home control panel. The home control panel is supplied with an output signal to be output from the home door apparatus if the home door apparatus is normally opened and closed. , And controls the opening and closing of the other home door devices as usual. Therefore, the home door device in which the abnormality has occurred is in a state of individual handling substantially independent of the system. Then, in the home door device in which the abnormality has occurred, the station door can be opened / closed by the station staff setting the second state and operating the manual opening / closing means. Therefore, it is possible to open and close the abnormal home door device without obstructing the control of the normal home door device, and while confirming the safety of passengers.

In addition, the home door device may have a door-jam detection safety sensor for detecting whether or not a pedestrian is sandwiched by a door panel of the home door device. In this case, the individual control panel has invalidation means of the safety sensor for detecting the pinch of the home door device, and when the safety sensor is invalidated by the invalidation means, the individual control panel is set to the first state. You.

When the content of the abnormality displayed on the display device relates to the safety sensor for detecting the pinch, the station staff invalidates the safety sensor having the abnormality by invalidating means. At this time, the individual control panel is set to the first state at the same time, and the home door device is in an individual handling state.
The door-jam detection safety sensor confirms that a person is caught or is about to be caught in the door panel, even if no staff is waiting by each platform door device. It is provided in order to prevent the passenger from getting in and out of contact with the passenger, and usually prevents the train from proceeding when the door-to-door safety sensor detects the passenger. Even if an abnormality occurs only in the safety sensor for detecting the pinch of a certain home door device, there is a possibility that the train cannot be operated. However, by disabling the door pinch detection safety sensor, it is possible to prevent trouble in train operation. In addition, since the opening and closing operation of the home door device in which an abnormality has occurred in the door-jam detection safety sensor can be performed by setting the second state, the station staff disables the safety sensor by the invalidation means, By checking the state of getting on and off of passengers by the side of the home door device where the sensor abnormality has occurred, opening and closing the home door device by operating the manual opening / closing means can prevent passengers from being caught by the door panel. Can be prevented.

The home door device includes a door panel that is opened and closed, an electric lock that locks the door panel when the door panel is closed, and an unlocking device that can manually unlock the electric lock. it can.

[0015] The content of the abnormality displayed on the display device is an electric lock unlock error (a state in which the lock is not unlocked automatically).
In this case, the station staff can unlock the electric lock by manually operating the unlocking device. Then, the home door device can be manually opened and closed by setting the second state by the setting means and operating the manual opening and closing means. The electric lock is locked so that the door panel is not opened when the vehicle is not entering the platform and the passenger panel is closed when the vehicle is not entering the platform. Is what you do. In other words, it is not directly related to the operation of the vehicle. It is not desirable that the failure of one of the electric locks makes it impossible for passengers to get on and off the vehicle.
Therefore, after manually operating the unlocking device of the electric lock to enable the passengers to get on and off, the opening and closing of the door panel is carried out by the station staff by the home door device where the electric lock has an abnormality, Do it manually. Therefore, there is no hindrance to the operation schedule of the vehicle while checking the safety of passengers.

When the individual control panel is set to the first state or the second state, an open confirmation signal indicating that the home door device is at a fully open position; And a close confirmation signal indicating that the home control panel is present.

When the home door device is normal, the individual control panel supplies an open confirmation signal when the home door device is fully opened and a close confirmation signal when the home door device is fully closed to the home control panel. For example, when opening a home door device,
When a certain home door device causes an abnormality and does not output the open confirmation signal, the station staff operates the setting means of the individual control panel in accordance with the content of the abnormality displayed on the display device to perform the first or second operation.
Set to the state of. As a result, an open confirmation signal is forcibly output from the individual control panel, and the home control panel determines that the home door device has also been normally opened. Therefore, since the opening confirmation signal has been received from all the home door devices, an all home door opening confirmation signal is output, and for example, the door of the vehicle is opened. The same applies when a close confirmation signal is supplied.
As described above, even if an abnormality occurs in some home door devices, the home control panel does not need to change any control. Of course, there is a station worker beside the home door device where the abnormality has occurred, and the manual opening / closing means is manually operated to open / close the home door device manually, thereby ensuring the safety of passengers.

The manual opening / closing means can be provided on the individual control panel. The individual control panel is provided with setting means for setting to the first or second state, and in addition to this, a manual opening / closing means is also provided, so that the individual control panel is set to the first or second state. After that, the home door device can be manually opened and closed while confirming the safety of passengers on the spot.

The individual control panel outputs an individual handling signal to the home control panel when the home door system is individually handled by setting to the first state or the second state. Based on the individual handling signal, information indicating the individually handled home door device can be displayed.

When an abnormality occurs in a specific home door device and the abnormality is individually handled by the setting means or the safety sensor invalidating means, the individual control panel corresponding to the specific home door device sends an individual handling signal to the home control panel. Is output. The display device indicates that the specific home door device is individually handled based on the individual handling signal. Therefore, it is possible to confirm which of the home door devices has an abnormality and is treated individually, for example, in a station room.

[0021] The display device may display first aid information for the abnormality based on the abnormality signal.

The display device displays first aid information indicating how to perform first aid for the abnormal home door device. According to the instructions in the contents, the station staff rushes to the abnormal home door device, Give first aid. Therefore, the station staff can take prompt action and do not hinder the operation of the vehicle.

The individual control panel has a normal recovery detecting means for detecting that the home door device in which the abnormality has been detected has returned to the original normal state and outputting a normal recovery signal to the home control panel. The display device may display information indicating the home door device that has returned to the normal state based on the normal return signal.

When the home door device in which the abnormality has occurred is repaired by the station staff and returned to the original normal state, the normal recovery detecting means outputs a normal recovery signal to the home control panel. Since the information based on the normal restoration signal is displayed on the display device, the station staff can know that the normal restoration has been performed by checking the display contents.

[0025] The abnormality signal is generated according to the content of each abnormality.
The highest ranking is given to those with a high degree of risk to passengers, and the display device displays only information based on the abnormal signal set at the highest rank among the output abnormal signals. You can do it.

When a plurality of abnormal signals are output and all of them are displayed on the display device, the station staff is confused as to which abnormality should be dealt with. Therefore, the display device displays only one of the abnormalities having the highest risk among the abnormalities that have occurred. Since only the one abnormality having a high risk is treated by the station staff, the labor of the station staff can be reduced, and the safety of passengers can also be improved.

The individual control panel outputs an open confirmation signal or a close confirmation signal to the home control panel when the home door device reaches the fully open position or the fully closed position, respectively. The opening and closing operation status of each home door device can be displayed based on the signal and the closing confirmation signal.

Therefore, the station staff can check not only the abnormally occurring home door device but also the normally opened and closed home door devices on the display device.

The home control panel and the individual control panel can communicate with each other by a double communication network arc of a communication network using multiplex communication and a communication network using relay contacts.

Therefore, when the communication by the communication network becomes impossible, the communication can be performed by the relay contact, so that at least the occurrence of the abnormality can be communicated to the home control panel.

[0031] The platform door system of the present invention comprises:
For each of a plurality of stations connected on a predetermined railway line, a plurality of home door devices, a plurality of individual control panels, a home control panel,
And a display device. The home control panel of each station and the central station central display device are connected so that the home door devices are centrally managed, and information displayed on the station office room display device can be displayed for each station. The individual control panel, in conjunction with the opening and closing control of the home door device, detects an abnormality of the home door device, has an abnormality detection unit that outputs an abnormality signal to the home control panel, the display device,
When the home control panel receives the abnormality signal, based on the abnormality signal, information indicating the home door device in which the abnormality has occurred and content information of the abnormality are displayed. The all-stations centralized display device, when the home control panel receives the abnormal signal, information indicating a station provided with the home control panel, and is displayed on the station service room display device based on the abnormal signal. Display information and. The all-station central display device can be provided, for example, at a transportation control center or the like.

FIG. 5 is a flowchart showing the control when the door panel 4 is opened in the individual control panel 6. First, it is determined whether the open position sensor 30 is on, that is, whether the door panel 4 is in the open position ( Step S2). If it is not on, an opening stroke process described later is performed (step S
4). After the end of the opening process, or when it is determined in step S2 that the open position sensor 30 is not on, it is determined whether a close signal is input (step S6). If the closing signal has not been input, the process returns to step S2. If the closing signal has been input, a closing process described later is performed (step S2).
8) The state shifts to the closed state.

In the closed state shown in FIG.
Is turned on (step S10). That is, it is determined whether the door panel 4 has reached the closed position. If it has not reached the closed position, a closing stroke is performed (step S12).
When the closing position sensor 32 is ON or after the closing stroke is completed, it is determined whether an open signal is input (step S1).
4) If not entered, the process returns to step S10. If entered, an opening process is performed (step S16), and FIG.
The state returns to the open state shown in FIG.

FIG. 7 shows the details of the opening process described above. In the opening stroke, first, an unlock signal of the electric lock 26 is output (step S18), and the electric lock 26 is unlocked. Next, an unlock diagnosis to be described later is performed (step S20). And the motor 24
An open signal is output so as to open the door panel 4 (step S22). Then, the opening timer is started (step S24).

Next, whether the closed position sensor 32 is off,
That is, it is determined whether the door panel 4 has moved from the closed position (step S26). If it is moving, a door panel in-operation signal is output (step S28). Subsequently, or when it is determined in step S26 that the closed position sensor 32 is not off, it is determined whether the open position sensor 30 is on, that is, whether the door panel 4 has moved to the open position (step S30).

If the door panel 4 has not moved to the closed position, it is determined whether the opening timer has timed out (step S32). If the time is not up, step S
Return to 26. If the time is up, the door panel 4 has not moved to the open position by the predetermined time despite the supply of the open signal, so that the door controller described below is diagnosed (step S34). If no abnormality has occurred, the open position sensor off abnormality diagnosis is performed (step S36). As a result of the diagnosis, if no abnormality has occurred, the time is over, but the closing operation is performed.
Opening operation time over error code is sent to the home control panel 6
Is output together with a number indicating the door device (step S38). In the following, an error code is output in various cases. In any case, a number indicating the door device is output to the home control panel 6 together with the error code.

Next, it is determined again whether the open position sensor 30 is on (step S40). If not, the door controller diagnosis (step S42) and the open position sensor off hold abnormality diagnosis (step S44) are repeated. If the open position sensor 30 is turned on, a normal return signal for the opening operation time over is output to the home control panel 6 together with a door number indicating the door device (step S46). In the following, a normal return signal is output in various cases, and a door number is output together with the normal return signal. Subsequent to step S46 or if it is determined in step S30 that the open position sensor 30 is ON, a closed position sensor ON holding abnormality diagnosis, which will be described later, is performed (step S48), and an open confirmation signal is output (step S50). .

As shown in FIG. 8, during the closing stroke, a closing signal is output to the motor 24 so as to close the door panel 4 (step S52). Then, the closing timer is started (step S54). Next, it is determined whether the open position sensor 30 is off (step S56).
A door panel operating signal is output (step S58). Subsequent to step S58 or if it is determined in step S56 that the open position sensor 30 is not off, it is determined whether the closed position sensor 32 is on (step S6).

Following step S84 or if the closed position sensor 32 is ON in step S62, an open position sensor ON holding abnormality diagnosis is performed (step S86).
A lock confirmation signal is output (step S88), a lock signal for the electric lock 26 is output (step S90), and lock diagnosis is performed (step S92).

FIG. 9 shows details of the unlocking diagnosis processing in step S20 in FIG. First, the unlocking timer is started (step S94), and it is determined whether or not the unlocking signal is ON, that is, whether or not the electric lock 26 is unlocked based on the unlocking signal of the electric lock in step S18 (step S96). If the unlock signal is not on, it is determined whether the unlock timer has expired (step S98), and if not, the process returns to step S96. If the unlock signal is ON, it can be determined that the electric lock 26 has been unlocked based on the unlock signal, and the unlock diagnosis is terminated. When the unlock timer expires in step S98, the electric lock 26 is not unlocked within the time set in the unlock timer, so that an electric lock unlock abnormality error code is output (step S100).

Next, it is determined whether or not the unlocking signal is on (step S102). If the unlocking signal is on, the electric lock 26 is naturally unlocked, and a normal operation for the electric lock unlocking error error is performed. A return signal is output (step S104), and the unlocking diagnosis ends.

If the unlocking signal is not ON, it is determined whether the switching means for individual handling is ON, that is, whether the manual-automatic switch 48 has been switched to the manual mode or the short-circuit-normal switch 50 has been switched to the short-circuit state ( Step S106) If it is not ON, step S106 is repeated.

When the short-circuit / normal switch 50 is switched to the short-circuit state, an interrupt routine is executed as shown in FIG. 10A, and an open confirmation signal, a close confirmation signal, a normal signal and an individual handling signal are output. (Step S10
8). Thereby, if the other door device 2 is normal,
The home control panel 6 can open and close the door devices 2 other than the abnormal door device 2. When the manual-automatic switch 48 is switched to manual, an interrupt routine is executed as shown in FIG. 10B, and an open confirmation signal, a close confirmation signal, a normal signal, and an individual handling signal are output (step S11).
0), operation of the manual open / close switch 54 causes the door panel 4

It is determined that the open position sensor 30 is not on, and at this time, it is determined whether the door has moved the full stroke (whether the door panel 4 has moved to the closed position) (step S13).
4). If the full stroke has not been made, the open position sensor 3
Even if 0 is off, since it cannot be determined that there is an abnormality, the open position sensor off abnormality diagnosis is terminated. When the full-stroke movement has been made, although the open position sensor 30 is supposed to be on, it is kept off, so that an open position sensor off hold error code is output (step S136), and the door panel 4 is stopped. (Step S138). Next, it is determined again whether the open position sensor 30 is on (step S1).
40) If it is ON, the normal state has been restored, so a normal return signal for the open position sensor OFF holding error is output (step S142), and this processing ends. If the open position sensor is not on, it is determined whether the switching means for individual handling is on (step S144).
Returning to step S140, if it is on, step S1
Repeat 44. When the switching means for individual handling is turned on, the interrupt routine of FIG. 10B is executed, and individual handling is executed.
