Description

Platform Door System {PLATFORM DOOR SYSTEM}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a platform door system having a plurality of foam door devices installed on a platform of a station and opening and closing in synchronism with a door of a railway vehicle.

When a railway vehicle arrives at the platform and the vehicle is stopped at the platform, the door panel of the platform door device installed at the position corresponding to the door of each vehicle is opened by the operation of the vehicle crew, and then the door of the vehicle is opened. At this time, in order to control each foam door device, an individual control panel installed in each foam door device outputs an open confirmation signal to the foam control panel integrating each individual control panel. When the foam control panel receives the opening confirmation signal from all the individual control panels, the foam control panel outputs the previous foam door opening confirmation signal to the vehicle. When the vehicle crew confirms the previous foam door opening confirmation signal, it determines that all the door panels are open and opens the door of the vehicle.

On the other hand, when the vehicle is departed from the platform, after the vehicle crew closes the vehicle door, the door panel is closed. At this time, the foam control panel transmits the entire foam door closing confirmation signal to the vehicle based on the closing confirmation signal from all the individual control panels. When the vehicle crew confirms the previous foam door closing confirmation signal, it determines that all the door panels are closed and starts the vehicle.

When attempting to open all the door panels of each foam door device, if a door panel does not open normally, the vehicle door corresponding to the door panel that is not opened is opened. This is dangerous for passengers. Therefore, the crew cannot open the vehicle door until it confirms that all the door panels are open or until it can determine that the safety of the passengers is secured even if the all door panels are not open. Similarly, when the door panel of the foam door device is closed when the door panel of the foam door device is not normally closed, the vehicle is started with the door panel of the foam door device open. This is also dangerous for passengers. Thus, the crew cannot start the vehicle until it can confirm that the door panels of all the foam door devices are closed or until all door channels are not closed but the safety of the passengers is secured.

When the door panel of the foam door apparatus cannot be normally opened and closed, the individual control panel of the foam door apparatus outputs an abnormal signal to the foam control panel. In the working room, a display device for displaying information based on this abnormal signal is provided. The display device displays information indicating that an abnormality has occurred and the foam door apparatus in which the abnormality has occurred. The station attendant who confirms the sign immediately runs to the place where the malfunctioning form door device is located, and the vehicle operation diagram is confusing unless the problem is quickly identified and the early recovery is attempted.

When an abnormality occurs in the form door apparatus, the station attendant who runs to the form door apparatus must immediately grasp the contents of the abnormality and make a judgment as to whether it can be recovered by performing maintenance immediately. However, it is difficult to make such a judgment quickly, it takes effort of a station employee, and delays recovery.

An object of the present invention is to provide a platform door system that makes it possible to quickly determine a countermeasure when an abnormality occurs in a foam door device.

In the platform door system according to the present invention, a plurality of foam door devices are installed on the platform. Individual control panels for individually opening and closing control of the respective foam door apparatuses are provided corresponding to the foam door apparatuses. Each individual control panel and form control panel communicate with each other. The foam control panel outputs an opening or closing signal for opening and closing the foam door device to each of the individual control panels. The display device is connected to this form control panel. The display device displays information based on signals obtained by mutual communication between the individual control panel and the form control panel. The individual control panel has abnormality detecting means for detecting an abnormality of the foam door apparatus in association with opening / closing control of the foam door apparatus and outputting an abnormal signal to the foam control panel. Various things can be considered as an abnormality of a foam door apparatus. The display device may be arranged, for example, in a station office in a station, and when the foam control panel receives the abnormal signal, information indicating the form door device in which the abnormality is generated based on the abnormal signal and information on the content thereof is further provided. Display. Information indicating the form door device in which the abnormality occurs can be generated separately from the abnormal signal.

When an abnormality occurs in the form door apparatus, for example, information indicating the form door apparatus in which the abnormality has occurred and the contents of the abnormality are displayed on the display apparatus of the work room. The station attendant can know the above contents by checking the display of the display apparatus, without having to go to the installation place of the foam door apparatus and perform the operation of confirming directly. Therefore, it is possible to head to the installation place of the foam door device in which an abnormality occurs after preparing in advance in the working room or the like for the treatment for the abnormality. When the station attendant reaches the installation site, it is possible to immediately take measures for the abnormality of the foam door device and to promote the early restoration of the system.

The individual control panel may have setting means for setting the platform door system to the first state and the second state. The first state is a state in which the opening or closing signal from the foam control panel is invalidated and the output signal output to the foam control panel is forcibly output if the foam door device is normally opened and closed. The second state is a state in which the opening or closing signal of the foam door device can be output by the manual opening and closing means in the first state. One setting means may set the first state and the second state, and setting means may be provided corresponding to each of the first state and the second state.

The station attendant who ran to the faulty foam door apparatus sets the first or the second state by operating the setting means of the individual control panel according to the above contents. In the first state, the open or close signal from the foam control panel is invalid, so that the abnormal door mechanism is not opened or closed in accordance with the instruction from the foam control panel. In addition, since the foam control panel is supplied with an output signal that should be output from the foam door device if the foam door device is normally opened and closed, the foam control panel also looks at the abnormal foam door device as normal. do. Thus, the faulty foam door device is substantially in a separate handling state independent of the platform door system. In addition, in the foam door apparatus in which the abnormality occurs, the station attendant can set the second state to open and close the foam door apparatus by operating the manual opening and closing means. Therefore, it is possible to open and close the foam door device, which does not interfere with the control of the normal foam door device, and also checks the passenger safety.

In addition, the foam door apparatus may have a door fitting detection safety sensor for detecting whether a passenger is fitted into the door panel of the foam door apparatus. In this case, the individual control panel has an invalid means of the safety sensor for door fitting detection of the foam door apparatus, and is set to the first state when the safety sensor is invalidated by this invalid means.

If the error indicated on the display device relates to the safety sensor for door insertion detection, the station official shall invalidate the safety sensor that caused this error by invalid means. At this time, the individual control panel is set to the first state at the same time, and the foam door device is in the individual handling state. The safety sensor for door insertion detection confirms that a person is inserted into or is likely to be inserted in the door panel even if no attendant is waiting next to each foam door device. It is installed to prevent it. Normally, when the safety sensor for door insertion detection detects an occupant, the train is not allowed to proceed. A fault in only the safety sensor for door-fitting detection of some form door devices can render the train impossible. However, it is possible to prevent the operation of the train by invalidating the safety sensor for door fitting detection. In addition, since the opening and closing operation of the foam door device having an abnormality in the safety sensor for door insertion detection can be performed by setting the second state, the station attendant invalidates the safety sensor by an invalid means, and then the foam door in which the safety sensor has an error It is possible to prevent the occupant from being fitted to the door panel by opening and closing the foam door apparatus by the manual opening and closing means while checking the elevating state of the occupant while being next to the apparatus.

The foam door apparatus may be provided with a door panel to be opened and closed, an electric lock for correcting the door panel in a closed state of the door panel, and a unlocking device capable of manually unlocking the electric lock.

If the abnormality indicated on the display device is abnormal for the electric lock release (a state in which the door panel is not automatically unlocked), the station attendant may release the electric lock by manually operating the unlocking device. Thereafter, the foam door apparatus can be opened and closed manually by setting means to the second state and operating the manual opening and closing means. Armature locks are installed to prevent passengers from accidentally falling onto the tracks when the vehicle does not reach the platform. The lock is fixed so that the door panel does not open with the door panel closed. The electric lock is not directly related to the operation of the vehicle. It is not desirable that an abnormality occurs in one of these locks, making it impossible for the passengers to get on and off the vehicle. Thus, the door panel is opened and closed manually while the station attendant is next to the foam door device having an abnormality in the electric lock, in a state in which the lifter of the electric lock is manually operated to enable the ascending and descending of the passengers. Therefore, it does not interfere with the vehicle operation diagram while confirming the passenger safety.

The individual control panel, when set to the first state or the second state, an open confirmation signal indicating that the form door device is in the full open position, and closing to indicate that the form door device is in the fully closed position. The confirmation signal may be forcibly output to the form control panel.

When the foam door apparatus is normal, the individual control panel supplies an opening confirmation signal when the foam door apparatuses are all open, and a closing confirmation signal when the foam door apparatuses are all closed, to the foam control panel. For example, when a foam door device is opened and a foam door device fails to output an opening confirmation signal, the station attendant operates the setting means of the individual control panel in accordance with the abnormality displayed on the display device, to thereby operate the first or second state. Set to. Accordingly, the open confirmation signal is forcibly output from the individual control panel, and the foam control panel determines that the foam door device is normally opened. Therefore, since the opening confirmation signal has been received from all the foam door apparatuses, all the foam door opening confirmation signals are output, for example, the door of the vehicle is opened. The same is true when the closing confirmation signal is supplied. Thus, even if some form door apparatuses fail, the foam control panel does not need to change the lower control. Of course, there is a station attendant next to the faulty foam door device while manually operating the manual opening and closing means to manually open and close the foam door device, ensuring passenger safety.

The manual opening and closing means may be installed in the individual control panel. The individual control panel is provided with setting means for setting in the first or second state. In addition to this setting means, a manual opening and closing means is also provided, so that the foam door device can be manually opened and closed while ensuring the safety of the passengers on the spot after being set in the first or second state.

The individual control panel may output an individual handling signal to the foam control panel when the foam door system is individually handled according to the setting to the first state or the second state. The display device displays information indicative of the individually handled form door device based on the individual handling signal.

When an abnormality occurs in a specific foam door apparatus and individually handled by the setting means or the safety sensor invalid means, the individual control panel corresponding to the specific foam door apparatus outputs an individual handling signal to the foam control panel. The display device indicates that the specific foam door device is being individually handled based on the individual handling signal. Therefore, it is possible to confirm, for example, in the station room which foam door device has an abnormality and is individually handled.

The display device may display emergency processing information for the abnormality based on the abnormality signal.

Since the display device displays emergency treatment information indicating an emergency treatment specification for a troubled foam door apparatus, the station attendant runs to the troubled foam door apparatus and performs first aid according to this instruction. Therefore, the station attendant can be promptly treated and does not interfere with vehicle operation.

The individual control panel may have a normal return detecting means for detecting that the foam door device in which the abnormality is detected returns to its original normal state and outputting a normal return signal to the foam control panel. In this case, the display device displays the information indicating the normally returned form door device based on the normal return signal.

When the faulty foam door apparatus is repaired by the station attendant and returned to the original normal state, the normal return detecting means outputs the normal return signal to the foam control panel. Since the information based on the normal return signal is displayed on the display device, the station attendant can confirm that the vehicle has returned to normal by confirming the display contents.

The abnormal signal may be ranked with the higher risk to the passenger according to the contents of each abnormality. In this case, the display device displays only information based on the abnormal signal in which the rank is set to the highest level among the abnormal signals output.

When a plurality of abnormal signals are outputted, all of them are displayed on the display device, and the station attendant will have a hard time dealing with the above. Thus, the display device displays only one abnormality having the highest risk among abnormalities that have occurred. Since only one or more of these high risks are dealt with by the station staff, the effort of the station staff can be reduced, and the safety of the passengers can also be improved.

The individual control panel may be configured to output an opening confirmation signal or a closing confirmation signal to the foam control panel, respectively, when the foam door device reaches the previous opening position or the previous closing position. In this case, the display device displays the opening / closing operation status of each foam door device based on the opening confirmation signal and the closing confirmation signal.

Therefore, the station attendant can confirm not only the foam door apparatus in which an abnormality has occurred, but also each foam door apparatus which opens and closes normally with a display apparatus.

The form control panel and the individual control panel may communicate with each other by a dual communication network of a communication network according to multiple communication and a communication network by a relay contact.

Therefore, when communication by the communication network becomes impossible, communication can be made by the relay contact, so that at least an abnormality can be communicated to the form control panel.

The platform door system of the present invention is provided with a plurality of foam door devices, a plurality of individual control panels, a foam control panel, and a display device for each of a plurality of stations connected on a predetermined railway line. The form control panel of each station and the entire station concentration display device may be connected to centrally manage each form door device, and information displayed on each station room display device may be displayed for each station. The individual control panel has an abnormality detecting means. The abnormality detecting means detects an abnormality of the foam door apparatus in conjunction with opening / closing control of the foam door apparatus and outputs an abnormal signal to the foam control panel. When the form control panel receives the abnormal signal, the display device displays information for displaying the form door device in which the abnormality is generated based on the abnormal signal, and further contents information. When the form control panel receives the abnormal signal, the entire station concentrated display device displays information indicating the station where the form control panel is installed, and information displayed on the station room display device based on the abnormal signal. The whole station concentration display device can be installed in, for example, a transportation command station located at a place away from each station.

The operating personnel at the central transportation command station can check the display of the entire station concentration indicator to confirm the abnormality of the form door devices at each station on the railway track under the control. As a result, information can be smoothly transmitted and shared with the station staff at each station. If the train operation diagram is confused due to an abnormality of the form door device, the central transportation command station can confirm the reason for the confusion by checking the display of the entire decentralized display device and respond appropriately.

(Example)

The platform door system of one embodiment of the present invention has a plurality of foam door devices 2 at one station as shown in FIG. These foam door devices 2 are provided on the up line and the down line of the platform of the station, respectively. These form door apparatus 2 are arrange | positioned in the position corresponding to each door of a railroad vehicle, respectively, when a railroad vehicle stops in the predetermined position of a platform. These foam door devices 2 have two door panels 4 that slide in opposite directions along a track, which is controlled to open and close.

In order to control the opening and closing of the door panel 4, each foam door apparatus 2 is provided with the individual control panel 6, respectively. These individual control panels 6 are connected to one foam control panel 8 provided on the platform. This connection is made such that the form control panel 8 and each individual control panel 6 form a loop through the multi-transmission signal line 10 and at the same time the form control panel 8 and each individual control panel 6 via the relay signal line 12. ) Is done to form a loop. The form control panel 8 and each individual control panel 6 can communicate with each other via the multi-transmission signal line 10.

When the vehicle 18 has reached a predetermined position of the ascending or descending platform, the crew of the vehicle 18 is the ascending or descending ground 16 and the ascending or descending vehicle information transmission device 14. Through the foam control panel 8 is given an opening instruction to open the door panel 4 of all the foam door device (2) up or down. The foam control panel 8 thus supplies an open signal to each individual control panel 6. Each individual control panel 6 responds to this opening signal, opens the corresponding door panel 4 and sends an opening confirmation signal to the foam control panel 8. When the foam control panel 8 receives the opening confirmation signal from all the individual control panels 6, the form control panel 8 transmits the full opening confirmation signal to the vehicle information transmission device 14 of the ascending or descending and the vehicle 16 (the ascending or descending grounder 16). 18). The crew of the vehicle 18 opens the vehicle door upon receiving the previous opening confirmation signal.

When the vehicle 18 departs from the platform, a crew member of the vehicle 18 signals the form control panel 8 to the form control panel 8 via the ascending or descending ground 16 and the ascending or descending vehicle information transmission device 14. To supply. The foam control panel 8 supplies a closing signal to each individual control panel 6. Each individual control panel 6 responds to this closing signal to close the corresponding door panel 4 and sends a closing confirmation signal to the foam control panel 8. When the foam control panel 8 receives the closing confirmation signal from all the individual control panels 6, the form control panel 8 transmits the full closing confirmation signal to the vehicle information transmission device 14 of the ascending or descending and through the ascending or descending ground 16. 18). The crew of the vehicle 18 closes the vehicle door upon receiving the previous closing confirmation signal.

The foam control panel 8 is also connected to the station office room display device 20 provided in the station office, and the general command room display device 22 of the general command room provided at a place away from the station. In addition, the platform door apparatus 2, the individual control panel 6, and the foam control panel 8 are provided for each station, and the foam control panel 8 and the general command room display device 22 of each station are multi-signal lines 10. Connected via

The foam door apparatus 2 has a motor 24 for opening and closing the door panel 4 in addition to the door panel 4 as shown in FIG. In addition, the foam door apparatus 2 also has an electric lock 26 for correcting the door panel 4 so as not to open the door panel 4 unintentionally when the door panel 4 is closed. This armature lock 26 can be released by operating the release button 28, as shown in FIG. These motors 24 and the electric lock 26 are controlled by the door control unit 27 of the individual control panel 6.

In addition, the foam door device 2 is provided with a door opening position sensor 30 and a door closing position sensor 32 for detecting whether the door panel 4 is located in the open position and the closed position, respectively. As these sensors 30 and 32, a photoelectric sensor can be used, for example. In addition, in order to detect whether a passenger is in contact with the door end of the door panel 4, that is, the front end, a door sensor 4 is provided with a safety sensor for detecting a door fitting, for example, a door end sensor 34. . As the door end sensor 34, for example, a bumper switch is used. Moreover, the obstacle sensor 36 is also provided in order to detect whether the obstacle exists in the passage which passes when the door panel 4 opens and closes. As the obstacle sensor 36, for example, a plurality of photoelectric sensors can be used.

The output of each sensor 30, 32, 34, 36 is supplied to the determination part 38 of the individual control panel 6. As shown in FIG. The determination unit 38 is also supplied with an open signal or a closed signal from the form control panel 8 via the communication control unit 40. The determination unit 38 opens and closes the door panel 4 as described later when these open signals or closed signals are received. In addition, the determination part 38 and the door control part 27 are comprised by CPU, ROM, RAM, EEPROM, etc., for example. In addition, at the time of performing this opening and closing, the diagnostic degree judging section 38 whether an abnormality has occurred in each of the sensors 30, 32, 34, 36, the motor 24, the electric lock 26, and the communication control section 40 at the same time. Do. When the form door device 2 is energized for the first time at start-up or the like, a diagnosis is also made as to whether there are any abnormalities in the CPU, RAM, ROM, EEPROM, and the like. As a result of these diagnosis, when there is no abnormality, the door normal signal is output to the foam control panel 6 through the relay signal line 12, and when there is an abnormality, the door abnormal signal, for example, an error code, is transmitted to the foam control panel 6 by the multi-signal transmission line. Output through 10, and at the same time the door normal signal via the relay signal line 12 is stopped. Thus, even if the multi-transmission fails for some reason, it is found out which foam door apparatus 2 has an abnormality on the foam control panel 6 side.

The foam control panel 8 has a control unit 42. The control unit 42 communicates with the command information transmitting unit 14, and simultaneously communicates with the station control room display unit 20, the general command room display unit 22, and each individual control panel 6 via the communication control unit 44. Communication is being performed by. The control unit 42 of the form control panel 8 is also constituted by a CPU, a RAM, a ROM, and the like.

The station office display device 20 is arranged in the station office. The station room display device 20 is constituted by, for example, a personal computer, and displays door states and failure details of up and down lines. The general command room display device 22 is also constituted by a personal computer, for example, and displays the state of the door panel 4 in all stations.

The individual control panel 6 has various indicators 44, as shown in FIG. The CPU normal indicator lights up when the CPU of the individual control panel 6 is operating normally, and the door normal indicator lights up when no abnormality as described later occurs. The open confirmation indicator lights up when the open position sensors of the left and right doors are on together. At this time, the open confirmation signal is output to the form control panel 8. The closing confirmation light turns on when the closing position sensors of the left and right doors are on together. At this time, the closing confirmation signal is supplied to the foam control panel 8. The open command and close command indicators light up when the open command (open signal) and the close command (close signal) are received from the form control panel 8. The obstacle up and down indicator lights up when the obstacle sensor detects the obstacle. Since the obstacle sensor is a photoelectric sensor disposed at intervals up and down, the sensor on the upper side is the sensor on the obstacle, and the sensor on the lower side is the sensor under the obstacle. The normal on the obstacle and the normal on the obstacle light up when the sensor on the obstacle and the sensor on the obstacle normal. When the sensitivity switch 46 is pressed, the sensitivity level can be confirmed by viewing the blinking speed of the indicator corresponding to each sensor that changes in accordance with the sensitivity state of each sensor. The release command indicator lights when the release command is given to the electric lock. The visibility indicator lights up when the lock pin of the lock is lowered and the limit switch for visibility confirmation is turned on. The open position indicator lights up when the open position sensor is turned on. The closed position sensor indicator lights up when the closed position sensor is turned on. The door end sensor indicator lights up when the door end sensor is turned on.

The individual control panel 6 is also provided with setting means such as a manual-automatic switching switch 48, a short-normal switching switch 50, and a door end sensor effective-invalid switching switch 52.

When an abnormality occurs, the short-normal changeover switch 50 is switched to the first state, that is, the short-circuit state. Accordingly, the open confirmation signal and the closing confirmation signal are forcibly outputted to the foam control panel 8 regardless of the presence or absence of power and the position of the door 4, and the door normal signal is also forcibly returned. The handling signal is also output through the multi-signal transmission line 10. Thereby, the other foam door apparatus 2 can be opened and closed based on the opening or closing signal from the foam control panel 6.

When the manual-automatic switching switch 48 is switched to the automatic side, the open and close signals from the foam control panel 8 become valid. When switching to the manual side, the manual open / close switch 54 provided in the individual control panel 6 becomes effective, and the door operator can open and close the door 4 by operating it. In addition, the door normal signal is forcibly returned, and the individual handling signal is output to the foam control panel 8 through the multiple transmission line 10. Therefore, the other foam door device 2 can be opened and closed based on the opening or closing signal from the foam control panel 6, and the door device 2 in which an abnormality occurs has a manual opening / closing switch next to the device. It can be opened and closed by operating 54, and the lifter can also be lifted and lifted from the vehicle through the door device 2.

The door end sensor enable-disable switch 52 activates the door end sensor 34 when switched to the effective side, that is, reopens the door panel 4 according to the output of the door end sensor 34. However, when this switch 52 is switched to the invalid side, the door end sensor 34 becomes invalid at the same time as the short circuit state. That is, the door panel 4 is not reopened according to the output of the door end sensor 34. Therefore, unnecessary reopening / closing operation of the door panel 4 due to the abnormality of the door end sensor 34 can be prevented.

The station office display device 20 indicates whether each foam door device 2 is open or closed. In addition, if there is a foam door device 2 having an abnormality, which form door device it is displayed is displayed on the station room display device 20, and also what kind of abnormality has occurred, and a countermeasure thereof is displayed on the station room room display device 20. . Since an abnormal door device and a countermeasure for the door device are displayed, it has been found how to be handled when a station attendant runs to the abnormal door device. Therefore, the station attendant can perform a quick process and can avoid the situation where a delay occurs in the driving diagram of a vehicle.

The general command room display device 22 displays the state of each form door device in the up and down lines of each station. For example, whether the door 4 of the form door device of each station is in an open state, a closed state, or the like is displayed for each station in the same manner as the station office room display device 20. In addition, as shown in FIG. 22, all stations may be concentrated and displayed. That is, the markings corresponding to the ascending and descending foam door devices are indicated corresponding to each station, and when the foam door device is open, the indication is red, and when it is closed, it is green, and when it is opening and closing, it is white. When this occurs, yellow flashes, and when it is handled as described later, blue flashes. Each station has a display indicating whether a vehicle exists in each station, and if present, the display lights. By the centralized display of the whole station, it is possible to immediately determine which state the form door device is in.

FIG. 5 is a flowchart showing the control when opening the door panel 4 in the individual control panel 6. First, whether the open position sensor 30 is on, that is, the door panel 4 is in the open position. It judges (step S2). When the open position sensor 30 is not turned on, an open stroke process described later is performed (step S4). If it is determined that the open position sensor 30 is not ON after the end of the open stroke or in step S2, it is determined whether a closed signal is input (step S6). If no closing signal is input, step S2 is executed again. If the closing signal is input, the closing stroke, which will be described later, is performed (step S8), and the state is shifted to the closing state.

In the closed state shown in FIG. 6, it is determined whether the closed position sensor 32 is on (step S10). That is, it is determined whether the door panel 4 has reached the closed position. If the closing position is not reached, the closing stroke is performed (step S12). When the closing position sensor 32 is on or after the closing stroke is finished, it is determined whether a closing signal is input (step S14). If no closing signal is input, the process returns to step S10. If the open signal is input, the open stroke is performed (step S16), and the flow returns to the open state shown in FIG.

The details of the open stroke described above are shown in FIG. In the open stroke, first, the unlock signal of the electric lock 26 is output (step S18) to unlock the electric lock 26. Next, the unlocking diagnosis described later is performed (step S20). Then, the open signal is outputted so that the door channel 4 is opened by the motor 24 (step S22). Then, the timer for opening is started (step S24).

Next, it is determined whether the closed position sensor 32 is off, that is, the door panel 4 is moving from the closed position (step S26). If it is moving, a signal during door panel operation is output (step S28). Subsequently, or if 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 is not moved to the closed position, it is determined whether the opening timer has timed up (step S32). If it has not timed up, the flow returns to step S26. If it is timed up, the door panel 4 is not moved to the open position until the predetermined time even though the open signal is supplied, and the door controller 4 to be described later is diagnosed (step S34). If no abnormality has occurred as a result of this diagnosis, the abnormality diagnosis of the open position sensor off is performed (step S36). If no abnormality has occurred as a result of this diagnosis, the time is over, but the closing operation is performed. Therefore, the opening operation timeover error code is output to the form control panel 6 together with the number indicating this door device (step S38). In addition, although the error code is output in various cases below, the number indicating the door device together with the error code is output to the form control panel 6 in either case.

Next, it is determined again whether the open position sensor 30 is on (step S40). If the open position sensor 30 is not on, the door controller diagnosis (step S42) and the open position sensor off holding abnormality diagnosis (step S44) are repeated. If the open position sensor 30 is turned on, the normal return signal for the open operation timeover is output to the form control panel 6 together with the door number indicating the door apparatus (step S46). In addition, although the normal return signal is output in various cases below, the door number is output together with this normal return signal. Subsequent to this step S46 or in step S30, when it is judged that the open position sensor 30 is ON, the closed position sensor ON holding abnormality diagnosis mentioned later is performed (step S48), and an open confirmation signal is output (step S50).

As shown in Fig. 8, in 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), and if it is off, a signal during the door panel operation is output (step S58). Subsequent to this step S58 or in step S56, if it is determined that the open position sensor 30 is not off, it is determined whether the closed position sensor 32 is on (step S60). In other words, it is determined whether the door panel 4 has reached the closed position (step S62).

If the closing position sensor 32 is not on, it is determined whether the closing timer has timed up (step S64). If it does not time up, the door engagement detection mentioned later is performed (step S66), and it returns to step S56.

When the closing timer times up, the door controller diagnosis (step S68), the closing position sensor off holding abnormality diagnosis (step S70), the door end switch off holding abnormality diagnosis (step S72) are performed, and the closing operation timeover error code is output. (Step S74).

Next, it is judged whether the closed position sensor 32 is on (step S76), and if it is not on, the door insertion detection (step S78), the door controller diagnosis (step S80), and the open position sensor off holding abnormality diagnosis (step S82) are performed. Repeat.

If the closed position sensor 32 is on, time is over, but since the door panel 4 is closed, a normal return signal for the closing operation timeover is output (step S84).

Subsequent to step S84 or in step S62, if the closed position sensor 32 is on, the closed position sensor ON holding abnormality diagnosis is performed (step S86), the closing confirmation signal is output (step S88), and the electric lock 26 The corrective signal is output (step S90), and the corrective diagnosis is performed (step S92).

The details of the unlocking diagnosis process of step S20 of FIG. 7 are shown in FIG. First, the unlocking timer is started (step S94), and it is determined whether 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 not, it is determined whether the release timer has timed up (step S98), and if not, the process returns to step S96. If the unlock signal is on, it is determined that the electric lock 26 has been unlocked based on the unlock signal, and thus the unlock diagnosis is finished. When the unlocking timer is timed up in step S98, since the electric lock 26 has not been released within the time set as the unlocking timer, an error lock unlocking error code is output (step S100).

Next, it is determined whether the unlocking signal is on (step S102). If the unlocking signal is on, the electric lock 26 is naturally released, so that the normal return signal for the error of the unlocking abnormality of the lock is output (step S104), and the unlocking diagnosis is finished. do.

If the unlock signal is not on, it is determined whether the switching switch for individual handling is on, that is, whether the manual-automatic switching switch 48 is switched manually or the short-normal switching switch 50 is switched to the short-circuit state (step S106). ). If the switch for individual handling is not turned on, step S106 is repeated.

When the short-normal switching switch 50 is switched to the short-circuit state, an intervention 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 S108). . Accordingly, if the other door device 2 is normal, the foam control panel 6 can open and close the door device 2 other than the door device 2 having an abnormality. When the manual-automatic switching switch 48 is manually switched, an intervention routine is executed as shown in Fig. 10B. As a result, the open confirmation signal, the close confirmation signal, the normal signal and the individual handling signal are output (step S110). Thereby, the door panel 4 can be opened and closed by the operation of the manual opening / closing switch 54. Accordingly, as described above, the foam control panel 6 can open and close the other door device, and the abnormal door device 2 can be opened and closed manually. Prior to manual opening and closing, the door panel 4 can be unlocked at this time by operating the release button 28 shown in FIG. 2.

11 shows the details of the door controller diagnosis displayed on steps S34, S42 in FIG. 7 and S80 in FIG. In this diagnosis, first, it is determined whether or not there is no abnormality in the door controller (step S114). In this diagnosis, for example, the belt caught on the motor 24 is not cut off, the motor 24 does not generate abnormal heat, the encoder for detecting the position of the door panel 4, or the like, or the door control unit (27) A judgment is made as to whether or not there is an error in the RAM, ROM, EEPROM, or the like constituting the judging section 38 and the like.

If there is no abnormality in the door controller, this door controller diagnosis is terminated. If the door controller is abnormal, the door controller error code is output (step S116) and the door panel 4 is stopped (step S118). Then, as described above, it is determined whether the changeover switch for individual handling is on (step S120), and this step S120 is repeated until the changeover switch is turned on. When the switch for individual handling is turned on, the individual handling of Fig. 10A is performed. When the switching switch (switch switch 48 or 50) for individual handling is turned on, it is judged whether the switches 48 and 50 for individual handling are turned off (step S122), and this step S122 is repeated until all are turned off. do. When all are turned off, the normal return signal for the door controller error is output (step S123), and the routine ends.

When all the switching switches to individual handling are turned off, the intervention processing routine shown in Fig. 12 is executed, and the open confirmation signal, the closing confirmation signal, and the individual handling signal are stopped (step S124). Next, it is determined whether the open position sensor 30 is on (step S126). If the open position sensor 30 is on, an open confirmation signal is output (step S128). Subsequent to this step S128 or in step S126, if it is determined that the open position sensor 30 is not on, it is determined whether the closed position sensor 32 is on (step S130). If the closing position sensor 30 is on, a closing confirmation signal is output (step S132), and this intervention routine is terminated. If the closed position sensor 32 is not turned on, this intervention routine ends. Accordingly, the opening or closing confirmation signal is output in accordance with the current state of the door 4.

FIG. 13 shows a detailed flowchart of the open position sensor off holding abnormality diagnosis shown in step S36, S44 of FIG. 7, and step S82 of FIG. In this process, for example, in step S30, S40 or S76, it is determined that the open position sensor 30 is not on, and at this time, it is determined whether the door has been moved all the stroke (the door panel 4 has been moved to the closed position). (Step S134). If the previous stroke has not been moved, even if the open position sensor 30 is off, it cannot be judged to be abnormal, and thus the open position sensor off abnormal diagnosis is finished. If the previous stroke has been moved, the open position sensor 30 remains off even though it is originally on, so that the open position 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 S140), and if it is turned on, the normal return signal for the open position sensor off holding error is output (step S142), and the process ends. do. If the open position sensor is not on, it is determined whether the switch for individual handling is on (step S144), and if not, the flow returns to step S140. If the switch for individual handling is turned on, step S144 is repeated. By turning on the switch for individual handling, the intervention routine of FIG. 10B is executed and individual handling is executed.

FIG. 14 shows a detailed flowchart of the closed position sensor ON holding abnormality diagnosis of step S48 of FIG. In this diagnosis, it is first determined whether the closed position sensor 32 is off (step S146). If the closed position sensor 32 is off, it is determined that the open position sensor 30 is on in step S30, and therefore, even if the closed position sensor 32 is off, no abnormality can be said. Thus, this process ends. If the closed position sensor 32 is not off, it is determined that the open position sensor is on in the previous step S30 of this diagnosis. Therefore, if the closed position sensor is not off, it can be determined that there is an abnormality that the closed position sensor is kept on. . Thus, the closed position sensor on hold error code is output (step S148), and the door panel 4 is completely opened to hold it (step S150).

Then, it is determined whether the closed position sensor 32 has returned to the off state (step S152). If not, it is determined whether the switching means for individual handling is on (step S154). If not, the process returns to step S152. If the individual handling switching switch is on, step S154 is repeated. Since the individual handling switch is on, the intervention processing shown in Fig. 10B is executed, and the individual handling is executed. If it is determined in step S152 that the closed position sensor is off, the closed position sensor 32 has naturally returned, and thus, the normal return signal for the closed position sensor on hold error is output (step S156), and the diagnosis is finished.

Fig. 15 shows a detailed flowchart of the closed position sensor off holding abnormality diagnosis indicated in step S70 of Fig. 8. In this diagnosis, first, it is determined whether the door panel 4 has moved previous stroke (stroke has been stroked to the fully closed position) (step S158). If it is not moved, even if the closed position sensor 32 is off, it cannot be said to be abnormal, so the diagnosis is terminated. If the closed position sensor 32 is off even though the door panel 4 has moved the previous stroke, the closed position sensor off holding abnormal error code is output (step S160) and the door panel 4 is stopped (step S162).

Then, it is determined whether the closed position sensor 32 is on (step S164). If the closed position sensor 32 is on, it automatically returns to the normal state, and therefore, the normal return signal for the closed position sensor off holding error is output (step S167) to complete the diagnosis. If the closed position sensor 32 is not on, it is determined whether the switch for individual handling is on (step S166), and if not, the process returns to step S164. If it is on, this step S168 is repeated. In addition, since the changeover switch is on, the intervention routine of Fig. 10B is executed, and individual handling is performed.

Fig. 16 shows a detailed flowchart of the door end switch-off holding abnormality diagnosis indicated in step S72 of Fig. 8. In this diagnosis, it is first determined whether the door panel 4 is stopped (step S170). If the door panel 4 is not stopped, even if the door end switch 34 is off, it cannot be regarded as abnormal, so the process ends. If the door panel 4 is stopped, the door end switch 34 is turned off even when the door panel 4 is moved to the previous closed position by the closing signal in step S52, and it is determined that there is an abnormality in the door end switch-off holding. Therefore, the door end switch-off holding error code is output (step S172). Then, the open signal is output to move the door panel 4 to the fully open position (step S174), and the door panel 4 is held at the deployed position (step S176).

Then, it is determined whether the switch for individual handling is on (step S178), and if it is on, this step S178 is repeated. Since the changeover switch is on, the intervention processing routine shown in Fig. 10B is executed, and the individual handling processing is executed. If it is determined that the switch for individual handling is not on, it is determined whether all of the switch for individual handling are turned off (step S180), and if it is not all off, this step S180 is repeated. If it is determined that all the switching switches to the individual handling are off, a normal return signal for the door end switch off holding error is output (step S182), and the diagnosis is finished. In addition, the intervention processing shown in Fig. 12 is executed in response to all of the switching switches for individual handling being turned off, and the opening and closing confirmation signals and the individual handling signals are stopped, and when the open position sensor is on, an open confirmation signal is generated. When the closed position sensor is turned on, a closing confirmation signal is output.

FIG. 17 shows a detailed flowchart of the door engagement detecting process shown in steps S66 and S78 of FIG. 8. In this process, first, it is determined whether the door end switch 34 or the obstacle sensor 36 is on (step S184). If the door end switch 34 or the obstacle sensor 36 is not on, the closed position sensor 32 is judged not to be ON in step S62 or S76 which was executed earlier, and thus the door end switch 34 or the obstacle sensor 36 is not on. This process is terminated because there is no abnormality in (36).

If it is determined that the door end switch 34 or the obstacle sensor 36 is on, the passenger may be caught in the door panel 4, and thus a reopening signal for opening the door panel 4 is output (step S186). ), The timer for re-opening is started (step S188).

Next, it is determined whether the output of the reopening signal is the third time (step S190), and if it is the third time, it waits for the reopening timer to time up (step S192). If it is timed up, a close signal is output (step S194), and this processing ends. Therefore, the door panel 4 is closed once again open.

If the output of the reopen signal is the third time, it is determined whether the open position sensor 30 is on (step S196). Even if the reopening signal is output three times, there is a possibility that something is wrong that the door end switch 34 or the obstacle sensor 36 is on. Therefore, if the open position sensor 30 is not on, the door controller is diagnosed. (Step S193), the closed position sensor off holding abnormality diagnosis (step S195) is performed, and a process returns to step S196. If the open position sensor 30 is on, the door end switch-on holding abnormality diagnosis is performed (step S197).

The door end switch on holding abnormality diagnosis determines whether the door end switch 34 is off, as shown in FIG. 18 (step S198). If the door end switch 34 is turned off, it is determined that the obstacle is present. Therefore, the obstacle error code is output (step S200), and the door panel 4 is completely opened to maintain the previous opening (step S202). Then, it is determined whether the switch for individual handling is turned on (step S204), and this step S204 is repeated until it is turned on. By turning on, the intervention processing routine of FIG. 10B is executed, and individual handling processing is performed. When the switch for individual handling is turned on, it is judged whether or not all of the switch for individual handling is off (step S206), and this step 206 is repeated until it is turned off. If all are turned off, the intervention process shown in Fig. 12 is executed, and the normal return signal for the trouble present error is output (step S208), and the diagnosis is completed.

If it is determined in step S198 that the door end switch 34 is not off, since the open position sensor 30 is determined to be on in step S196, it is determined that the door end switch 34 is not off. It seems that there is an abnormality in maintenance. Thus, the door end switch on holding error code is output (step S210). Then, the door panel 4 is completely opened to maintain the previous opening (step S212).

Next, it is determined whether the door end switch 34 is off (step S214). If the door end switch 34 is off, the door end switch 34 naturally returns to the normal state, so that the normal return signal for the door end switch on holding error is output (step S216), and the diagnosis is finished. If it is determined in step S214 that the door end switch 34 is not off, it is determined whether the switch for individual handling is turned on (step S218), and if it is not on, the flow returns to step S214. Repeat. If the switch for individual handling is on, the intervention routine of Fig. 10C is executed and individual handling is executed. That is, the open confirmation signal, the close confirmation signal, the normal signal and the individual handling signal are output (step S217), and the door end switch 34 is invalidated (step S219).

FIG. 19 shows a detailed flowchart of the open position sensor ON holding abnormality diagnosis of step S86 of FIG. In this diagnosis, it is first determined whether the open position sensor 30 is off (step S220). If it is determined that the open position sensor 30 is not off, the closed position sensor 30 is judged to be on in step S62, and thus it cannot be determined that the open position sensor 30 is abnormal. Thus, this diagnosis ends.

If it is determined that the open position sensor 30 is off, the open position sensor 30 is judged to be on in step S62, and thus the open position sensor off holding is judged to be abnormal. Thus, the open position sensor on hold error code is output (step S222). Then, the door panel 4 is completely opened and the previous open state is maintained (step S224).

Next, it is determined whether the open position sensor 30 is off (step S226), and if it is off, the open position sensor 30 naturally returns to a normal state, and therefore a normal return signal for the open position sensor on hold error is outputted ( Step S228) This diagnosis ends. If it is determined that the open position sensor 30 is off, it is determined whether the switch for individual handling is on (step S230), and if it is not on, step S226 is executed. If it is on, step S230 is repeated. In response to the switch for individual handling being on, the intervention processing in Fig. 10B is executed and the individual handling is performed.

20 is a detailed flowchart of the visibility diagnosis of step S92 of FIG. 8. In this diagnosis, the timer for correction is first started (step S232). It is determined whether the correction signal is on (step S734). If it is on, since it is corrected in response to the output of the correction signal in step S90, it cannot be determined that there is an error in the correction. Thus, this diagnosis ends. If the correcting signal is not on, it is determined whether the correcting timer has timed up (step S236). If it has not timed up, the process returns to step S234. If it is time-up, an error code of the electronic lock timing error is output (step S238). Then, it is judged whether the corrective signal is on (step S240), and if it is on, it naturally returns to the normal state, so that the normal return signal for the electric lock corrective error is output (step S242), and the diagnosis is finished.

If the correction signal is not on, it is determined whether the switch for individual handling is on (step S244). If not, the control returns to step S240 if the switch is on, and if it is on, the step S244 is repeated. If the switching means for individual handling are on, the intervention processing routine in Fig. 10B is executed to perform individual handling.

21A shows a flowchart of the display processing of the office room display device 20. In this display process, the form number indicating the up or down form of the form transmitted from the form control panel 8, the number of a normal door device in this form, the number of an abnormal door device, an error code, and an individual handling signal are displayed. It receives (step S246).

Next, based on the normal door number, the position corresponding to the normal door apparatus, the position corresponding to the abnormal door apparatus, and the door apparatus handled separately are displayed (step S248). Next, data including the abnormal door number and the error code are inserted into the data list (step S250). The data list is rearranged in the order of the preset order (step S252). Based on the highest data, the door number, the contents of the abnormality, and the emergency treatment method are displayed (step S254).

For example, in the office room display device 20, the priorities of the abnormalities are determined, for example, the first position is the obstacle, the second position is the door end switch on, and the third position is the door end switch off. It is determined as follows. In addition, emergency measures for each abnormality are also memorized. For example, in the case of the door end switch-on holding, the door end sensor invalid-effective changeover switch is invalidated, in the case of the door end switch-off holding, the manual-automatic changeover switch 48 is switched to the manual side. When a plurality of abnormalities occur in one door apparatus, only the abnormalities having the highest priority and the countermeasures thereof are displayed.

21B shows display processing performed by the station room display device 20 when the abnormal state of the door device is automatically returned. In this display process, first, the form number, the door number returned to the normal state, and the normal return signal are received from the form control panel 6 (step S256). Next, based on the normal return signal and the normally returned door number, the display of the door device displayed as the abnormally generated door is changed to the normal return display (step S258).

In the general command room display device 22, similarly to the station room display device 20, the state of each form door device can be displayed in detail for each station. In addition, as shown in FIG. 22, the state of the form door apparatus 2 of each station can also be displayed intensively.
