Of these, the step 2 is for a user who is a target of use of the escalator 1 and is supported with an inclination angle set by a truss (not shown), and is driven by a drive device (not shown). Circulately moves between the entrances 10 located at both ends in the vertical direction. At that time, in the state where the step 2 faces the outside, that is, the state where the step 2 can be visually recognized from the outside, most of the step 2 moves in the form of a stepped platform so that the user can ride. ing. The steps 2 provided in this way are formed by, for example, aluminum die casting.

  The balustrade panel 4 is disposed on both the left and right sides of the step 2 so as to face each other across the plurality of steps 2 when the direction orthogonal to the moving direction of the step 2 facing the outside is the left-right direction. The balustrade panel 4 is made of, for example, transparent glass or acrylic. Further, the handrail belt 6 is a hand that the user puts on, and is wound around each peripheral portion of the balustrade panel 4 so as to be movable, and is synchronized with the movement (including the moving direction) of each step 2 by the driving device. Moving. The handrail belt 6 is made of rubber or the like. The operation of the escalator 1 provided in this way can be controlled by a control device 20 provided in a control panel (not shown), and the control panel is installed in a machine room provided below the entrance 10. .

  The escalator 1 is provided with a safety circuit 14 that can stop the escalator 1 that is operating in order to ensure safety during operation. The escalator 1 is provided with a safety device 12 that is a device that detects a state in which the degree of safety during operation is reduced at a plurality of locations by a technique according to the location, and the safety circuit 14 includes the safety device 14. 12 is connected. The safety circuit 14 stops the escalator 1 through the control device 20 by transmitting a control signal to the control device 20 when the safety device 12 detects an event related to the reduction in the safety degree. It is configured to be able to. The “event related to the reduction in the safety level” is, for example, that an abnormality such as a foreign object has been caught in an operation part of the escalator 1 such as between the step 2 of the escalator 1 or between the step 2 and the deck 5. Can be mentioned. In the present embodiment, such a process of stopping the escalator 1 when any abnormality is detected during the operation of the escalator 1 is referred to as “abnormal stop”.

  As a specific example of the abnormal stop control, for example, the belt retracting port 8 that is the retracting port of the handrail belt 6 that moves along the peripheral portion of the balustrade panel 4 includes a user's hand in the belt retracting port 8. A belt inlet safety device (not shown) is provided as a safety device 12 that detects these when a foreign object is caught, and the safety circuit 14 is also connected to the belt inlet safety device. The safety circuit 14 connected to the belt inlet safety device transmits a control signal to the control device 20 when the belt inlet safety device detects that a foreign object or the like is caught in the belt inlet 8. Thus, the abnormal stop control is executed via the control device 20.

  An operation indicator 3 (information display device) is provided at a position at which the user getting on the escalator 1 can recognize the entrance 10 of the escalator 1. In the example shown in FIG. 1, the operation indicator 3 is embedded on the deck 5 below the belt inlet 8.

  During normal driving, the operation indicator 3 displays an arrow mark indicating the driving direction of the escalator 1 at the entrance, and displays an entry prohibition mark for preventing reverse entry at the exit, so that the driving status of the escalator 1 can be indicated to the user. Configured to present.

  And especially in this embodiment, when the abnormal stop control is implemented, the escalator 1 is configured to be able to present information related to the abnormal stop necessary for recovery to the administrator using the two-dimensional code. Has been. Next, with reference to FIGS. 2-4, the structure of the abnormal stop presentation system 50 for showing the manager of the escalator 1 the required information regarding the said abnormal stop at the time of the abnormal stop of the escalator 1 is demonstrated. FIG. 2 is a diagram showing a schematic configuration of the abnormal stop presentation system 50 that presents information related to the abnormal stop of the escalator 1 of FIG. 1, and FIG. 3 shows the operation in FIGS. 1 and 2 when the escalator 1 is abnormally stopped. FIG. 4 is a diagram showing an example of the display screen content of the display 3. FIG. 4 shows the mobile terminal 30 on which information based on the two-dimensional code 3a is displayed after the mobile terminal 30 in FIG. 2 reads the two-dimensional code 3a. It is a figure which shows an example of the display screen 31 of.

  As shown in FIG. 2, the abnormal stop presentation system 50 includes the escalator 1, a portable terminal 30 carried by the administrator of the escalator 1, and a maintenance company server 40 of the maintenance company of the escalator 1. Is done.

  As components related to the abnormal stop presentation system 50 in the escalator 1, as shown in FIG. 2, the safety device 12, the safety circuit 14, the operation indicator 3, and the control device 20 may be mentioned.

  In the present embodiment, when the escalator 1 is abnormally stopped, the control device 20 aggregates information necessary for responding to the abnormal stop, such as the cause of the abnormal stop and a recovery method, and converts the information into a two-dimensional code 3a. It has a function to do. With regard to such a function, the abnormal stop control unit 22, the stop state storage unit 24, and the two-dimensional code conversion unit 26 are provided.

  The abnormal stop control unit 22 receives the control signal from the safety circuit 14 based on the detection of the event related to the reduction of the safety level of the escalator 1 by any of the plurality of safety devices 12 in the escalator 1 as described above. In response, abnormal stop control is performed to stop the escalator 1 by controlling the drive device (not shown). Further, the abnormal stop control unit 22 selects and determines the type of “stop cause information” indicating the cause of the abnormal stop, and transmits it to the two-dimensional code conversion unit 26 with the execution of the abnormal stop control.

  Here, for the stop cause information, for example, a plurality of types can be set in advance for each location or component where an occurrence of an abnormality is detected in the escalator 1. For example, as shown in FIG. 4, the specific contents can be set as “upper handrail belt inlet opening abnormality” or the like. The abnormal stop control unit 22 determines the current abnormality based on the determination criteria such as which safety device 12 in the escalator 1 has detected an abnormality and which safety circuit 14 has transmitted a control signal for abnormal stop control. Stop cause information regarding the stop can be selected and determined.

  The stop state storage unit 24 stores the above-described stop cause information and “recovery information” indicating a countermeasure for recovering from the abnormal stop of the escalator 1 in association with each other. The recovery information is individually preset for each cause of the abnormal stop of the plurality of stop cause information.

  Here, the recovery information can be set to an amount of information that allows the manager of the escalator 1 to immediately determine whether or not the abnormal stop can be easily resolved at the site when the abnormal stop occurs. For example, as shown in Fig. 4, the content of "Remove the foreign matter from the upper handrail belt inlet and restart the escalator" for the cause of the abnormal stop "Upper handrail belt inlet abnormal" Can be set.

  Moreover, the stop state storage unit 24 further acquires “detailed correspondence information” that is stored in the server 40 of the maintenance company of the escalator 1 and indicates a more detailed countermeasure for recovering from the abnormal stop via the Internet. "URL information" indicating the URL (Uniform Resource Locators) of the access destination for the access is also stored. The detailed correspondence information is individually set for each stop cause information in the same manner as the recovery information. Therefore, the URL information for acquiring each detailed correspondence information from the maintenance company server 40 is also set for each stop cause information. Set individually. That is, the stop state storage unit 24 stores a plurality of sets of stop cause information, recovery information, and URL information as one set.

  When the abnormal stop control is performed by the abnormal stop control unit 22, the two-dimensional code conversion unit 26 is based on the stop cause information indicating the cause of the current abnormal stop, and the recovery information and URL associated with this stop cause information Information is acquired from the stop state storage unit 24, and the information is collected and converted into the two-dimensional code 3a.

  Here, the “two-dimensional code” means a display-type code having information in the horizontal direction and the vertical direction with respect to a one-dimensional code (bar code) having information only in the horizontal direction. . The two-dimensional code can encode more information than the barcode, and can reduce the printing area. As the format of the two-dimensional code, for example, a matrix type in which small squares are arranged vertically and horizontally (for example, QR code (registered trademark), SP code, Vericode, Maxicode, CP code, DataMatrix, Code1, AztecCode, Intactor code) , Card e) and a stack type (for example, PDF417, Code49, Code16K, Codblock, SuperCode, Ultra Code, RSS Composite, AztecMesa) in which a plurality of one-dimensional barcodes are stacked one above the other.

  As shown in FIGS. 2 and 3, when the escalator 1 is abnormally stopped, the operation indicator 3 uses the two-dimensional code 3a to provide information necessary for responding to the abnormal stop, such as the cause of the abnormal stop and the recovery method. It is configured to display. Here, “information necessary for responding to an abnormal stop” in the present embodiment refers to whether or not the administrator of the escalator 1 can immediately perform recovery work by itself, or the cause of the abnormal stop being maintained. It means information sufficient to determine whether or not the company should be contacted, and includes the above stop cause information, recovery information, and URL information. FIG. 3 is an example of the display screen content of the operation indicator 3 when the escalator 1 is abnormally stopped. The cause information of the stop, the recovery information, which is created by the conversion by the two-dimensional code conversion unit 26 of the control device 20. The two-dimensional code 3a including the URL information is displayed on a part of the display screen of the operation indicator 3 as shown in FIG. Further, as shown in FIG. 3, the operation indicator 3 displays, in addition to the two-dimensional code 3a, character string information 3b and graphic information associated with the cause of the stop in addition to the two-dimensional code 3a when the escalator 1 is abnormally stopped. May be.

  The portable terminal 30 is a terminal device carried by the administrator of the escalator 1, and has a two-dimensional code reading function that can read the two-dimensional code 3a using a camera function or the like. When the portable terminal 30 reads the two-dimensional code 3 a displayed on the display screen of the operation display 3 as shown in FIG. 2, the portable terminal 30 re-converts the read two-dimensional code 3 a into character information and displays it on the display screen 31. To do.

  FIG. 4 shows an example of the display screen 31 of the portable terminal 30 at the time of reading the two-dimensional code. “Stop status details (upper handrail belt retractor abnormality)” based on stop cause information, “Restore method ( "Remove foreign matter from the upper handrail belt inlet and restart the escalator)" and "detailed information (http: // maintenance company information address)" based on the URL information.

  Further, the mobile terminal 30 has a communication function using the Internet network N. The portable terminal 30 uses this communication function to establish communication connection with the maintenance company server 40 via the Internet N based on the URL information acquired from the escalator 1, and the correspondence information storage unit 42 of the maintenance company server 40. “Detailed correspondence information” can be acquired from The mobile terminal 30 includes a mobile phone, a PHS, a PDA (Personal Digital Assistant), a personal computer, and the like having the above two-dimensional code reading function and communication function.

  The maintenance company server 40 is a server installed in the maintenance company of the escalator 1 and includes a correspondence information storage unit 42 that stores the above-mentioned “detailed correspondence information”. The maintenance company server 40 provides detailed correspondence information stored in the correspondence information storage unit 42 to the portable terminal 30 via the Internet network N.

  The control device 20 and the maintenance company server 40 of the escalator 1 are physically computers having a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), and the like. The functions of the control device 20 and the maintenance company server 40 described above are realized by reading and writing data in the RAM and ROM by loading an application program held in the ROM into the RAM and executing it by the CPU. The

  Next, with reference to FIG. 5, operation | movement of the abnormal stop presentation system 50 containing the operation indicator (information display apparatus) 3 which concerns on this embodiment is demonstrated. FIG. 5 is a flowchart showing stop information presentation processing in the abnormal stop presentation system 50 including the operation indicator (information display device) 3 according to the present embodiment. The process shown in the flowchart of FIG. 5 is performed when an abnormality is detected in the escalator 1.

  First, in the escalator 1, the escalator 1 is abnormally stopped by the abnormal stop control unit 22 of the control device 20 in accordance with a control signal from any safety circuit 14 in the escalator 1 (S101). Stop cause information indicating the cause is selected and determined (S102) and transmitted to the two-dimensional code conversion unit 26.

  Next, by using the stop cause information received from the abnormal stop control unit 22 by the two-dimensional code conversion unit 26 of the control device 20, the recovery information and URL information associated with the stop cause information are stored in the stop state storage unit 24. (S103), the stop cause information, the recovery information, and the URL information are combined and converted into a two-dimensional code 3a (S104). The two-dimensional code conversion unit 26 transmits information on the created two-dimensional code 3 a to the operation display 3.

  Then, as shown in FIG. 3, for example, the two-dimensional code 3a is displayed on the display screen by the operation display 3 (S105).

  On the other hand, it is confirmed by the portable terminal 30 whether or not the two-dimensional code 3a displayed on the operation display 3 has been read in the own apparatus by the operation of the administrator of the escalator 1 that owns the portable terminal 30 (S106). ). When it is confirmed that the two-dimensional code 3a has been read, the two-dimensional code 3a is reconverted into character information. For example, as shown in FIG. 4, stop cause information, recovery information, URL information is displayed on the display screen 31. Information based on is displayed (S107).

  Furthermore, the URL information on the display screen 31 is selected by the operation of the administrator of the escalator 1 that owns the portable terminal 30 by the portable terminal 30, and the process of accessing the maintenance company server 40 based on the URL information is performed. It is confirmed whether or not (S108). When the access process is performed, the detailed correspondence information associated with the stop cause information is acquired from the correspondence information storage unit 42 of the maintenance company server 40, and the content of the detailed correspondence information is displayed on the display screen 31 of the mobile terminal 30. (S109). If the access process has not been performed, the process ends.

  As a result of such processing, information necessary for recovering from an abnormal stop (stop cause information, recovery information, URL information, or detailed correspondence information) is collectively presented on the display screen 31 of the mobile terminal 30. It becomes the situation. The administrator of the escalator 1 that owns the portable terminal 30 refers to these information to determine whether or not the escalator 1 can be recovered by the administrator himself / herself. It can be determined whether or not it is necessary to request a dispatch.

  Next, the effect of the operation indicator (information display device) 3 according to the present embodiment will be described.

  The operation indicator 3 is provided on the escalator 1 that operates so that the steps 2 connected endlessly move around, and graphic information such as an arrow mark and an entry prohibition mark indicating a traveling direction during normal operation, and simple characters The purpose is to display information. Moreover, although the operation indicator 3 is installed in the entrance / exit 10 of the escalator 1 in the position which the user who gets into the escalator 1 can recognize, the size may be limited on account of installation space. For this reason, the display screen of the operation indicator 3 is limited to a small size that can display the graphic information and the character information, and the amount of information that can be presented at one time is limited.

  Therefore, the operation indicator 3 according to the present embodiment is configured to display information necessary for responding to the abnormal stop with the two-dimensional code 3a when the escalator 1 stops abnormally.

  Since the two-dimensional code 3a can encode character information and express it in a small print area, the operation display device 3 with a small display screen and limited by the above-described configuration of the present embodiment can be compared with character information. A lot of information can be transmitted. If the administrator of the escalator 1 uses a portable terminal 30 or the like having a function of reading the two-dimensional code 3a, the manager of the escalator 1 automatically performs the operation of reading the two-dimensional code 3a displayed on the operation display 3, and automatically Since the dimension code 3a is re-converted into character information and displayed on the display screen 31 of the portable terminal 30, it becomes possible to easily acquire information necessary to cope with an abnormal stop of the escalator 1.

  As described above, according to the operation indicator 3 according to the present embodiment, when the escalator 1 is abnormally stopped, it is necessary to deal with the abnormal stop without considering the size restriction of the display screen of the operation indicator 3. It becomes possible to present information quickly and easily. As a result, the manager of the escalator 1 refers to this information and determines whether or not the escalator 1 can be restored by the manager himself / herself, or cannot be restored by himself / herself, and requests the maintenance company to dispatch a technician. It becomes possible to determine whether or not it is necessary. As a result, the recovery operation can be performed efficiently, and the time until recovery can be shortened.

  Further, according to the operation indicator 3 according to the present embodiment, the “information necessary for responding to an abnormal stop” included in the two-dimensional code 3a is held in the escalator 1 (stop state storage unit 24). The “stop cause information” indicating the cause of the abnormal stop and the “recovery information” indicating the countermeasure for recovering from the abnormal stop are included.

  With this configuration, if the mobile terminal 30 having the function of reading the two-dimensional code 3a is used, the cause of the abnormal stop of the escalator 1 and the countermeasures can be directly presented to the administrator of the escalator 1, so that the recovery work period can be shortened. Can be planned.

  Further, according to the operation indicator 3 according to the present embodiment, the “information necessary for responding to an abnormal stop” included in the two-dimensional code 3 a is held in the server 40 of the maintenance company of the escalator 1. Further, “URL information” to the maintenance company server 40 for acquiring “detailed correspondence information” indicating a more detailed countermeasure for recovering from an abnormal stop via the Internet is included.

  With this configuration, it is possible to present detailed response information indicating a more detailed countermeasure even in a situation where the recovery method is not clear only by the content of the above-mentioned “recovery information”. Therefore, the response to the abnormal stop of the escalator 1 can be more accurately performed. Can be anything.

  In addition, according to the operation indicator 3 according to the present embodiment, the two-dimensional code 3a is displayed on the operation indicator 3 together with the character string information 3b (or graphic information) associated with information necessary for dealing with an abnormal stop. Displayed on the display screen.

  With this configuration, the administrator of the escalator 1 can perform procedures such as referring to a manual or making an inquiry to a maintenance company based on the character string information 3b (or graphic information) instead of the two-dimensional code 3a. Since the information necessary for responding to the associated abnormal stop can be acquired, the information necessary for responding to the abnormal stop can be presented without using the portable terminal 30 having the reading function of the two-dimensional code 3a. Can do.

  In the above embodiment, “information necessary for responding to an abnormal stop” displayed as the two-dimensional code 3a includes stop cause information, recovery information, and URL information. In addition, measurement information measured at the time of past maintenance and inspection work may be included. Examples of such measurement information include measurement data such as a slip distance when the brake slip of the escalator 1 is measured. Further, when the portable terminal 30 acquires the measurement information by reading the two-dimensional code 3a, the measurement information may be automatically transmitted to the maintenance company server 40 and stored. It is also possible to automatically create a periodic maintenance inspection report based on the above.

  In the above embodiment, the “information necessary for responding to an abnormal stop” displayed as the two-dimensional code 3a includes information related to only the last abnormal stop when the escalator 1 stops abnormally. However, it is good also as a structure also including the information regarding the log | history of the past abnormal stop of the said escalator 1. FIG.

  Further, the two-dimensional code conversion unit 26 of the control device 20 of the escalator 1 generates the two-dimensional code 3a by encrypting it, and the portable terminal 30 uses a decryption key that can decrypt the encrypted two-dimensional code 3a. It is good also as a structure to hold | maintain. With this configuration, it is possible to prevent a third party who does not have the decryption key from reading the two-dimensional code 3a displayed on the operation display 3.

  Moreover, in the said embodiment, the escalator 1 was provided with the operation indicator 3, and when the escalator 1 stopped abnormally, the two-dimensional code 3a containing the information required to respond to the abnormal stop was displayed on the operation indicator 3. However, the information display device of the present embodiment can also be applied to an escalator that does not include the operation indicator 3. In this case, an information display device for displaying the two-dimensional code 3a may be separately installed.

  Moreover, in the said embodiment, according to the abnormal stop control part 22 of the control apparatus 20 stopping the escalator 1 abnormally, the information for responding to this abnormal stop is displayed on the operation display 3 by the two-dimensional code 3a. However, the process of displaying the two-dimensional code 3a is not limited to when the escalator 1 is stopped abnormally. For example, when any abnormality is detected in the escalator 1, the escalator 1 can be operated, but such a state is also detected when a work such as inspection or replacement of the location where the abnormality is detected becomes necessary. In response to the occurrence of this, information necessary to respond to this state can be displayed on the operation display 3 with the two-dimensional code 3a. In addition, such a state and the abnormal stop state of the above embodiment are referred to as “abnormal state” in the present invention.

  Moreover, in the said embodiment, although the escalator 1 was mentioned and demonstrated as an example of the passenger conveyor which operate | moves so that the step connected endlessly may move around, the operation indicator 3 (information display apparatus) which concerns on this embodiment is shown. The present invention is not limited to the escalator 1 and can be similarly applied to other types of passenger conveyors such as a moving sidewalk.

  Although the embodiment of the present invention has been described, the above embodiment is presented as an example, and is not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention.
