Furthermore, a control unit, a storage unit, a communication interface, and the like are provided in the communication terminal device 19.

  Next, the configuration of the monitoring center 16 will be described.

  The monitoring center 16 remotely monitors the elevators 12a to 12e shown in FIG. 1 using a public line or the like. A monitoring device 17 is installed in the monitoring center 16 and various instructions are given by an operator. Moreover, while receiving the communication from the maintenance staff 14 via the monitoring apparatus 17, it communicates mutually and gives an instruction | indication suitably. The monitoring device 17 includes a computer that performs a predetermined program operation.

  FIG. 7 is a block diagram showing a functional configuration of the monitoring device 17 in the monitoring center 16.

  The monitoring device 17 includes a control unit 51, a storage unit 52, a communication interface 53, an input unit 55, and a display unit 56.

The storage unit 52 includes, for example, a ROM and a RAM, and stores various data including programs. The storage unit 52 is provided with a maintenance database (hereinafter referred to as maintenance DB) 52a and an emergency call database (hereinafter referred to as emergency call DB) 52b.

  The maintenance DB 52a is a database that stores information related to maintenance and inspection work performed by maintenance personnel. As shown in FIG. 8, in this maintenance DB 52a, the management number (terminal ID) of the information transmitter 15 possessed by the maintenance staff 14 at the time of inspection work, the identification number of the maintenance staff 14 (maintenance staff ID), name, affiliation Work information for managing the work situation at each site is stored along with information such as the name of the business (office name, title).

  The emergency call DB 52b is a database that stores information relating to passenger emergency calls. As shown in FIG. 9, the emergency call DB 52b stores a property ID for identifying each site and guidance information corresponding to each site. The guidance information is composed of a plurality of item data for confirming the state of the car room in stages, and when there is an access request by reading the second two-dimensional code 28 for passengers, a question format Is selectively transmitted to the communication terminal device 19.

  Next, the operation of the maintenance / inspection management system according to the present embodiment will be described focusing on the processing on the monitoring center 16 side.

  FIG. 10 is a flowchart showing the processing operation of the monitoring device 17 in the monitoring center 16. Note that the processing shown in this flowchart is executed by the control unit 51, which is a microcomputer, reading a predetermined program.

  When the read signal of the first two-dimensional code 27 or the second two-dimensional code 28 provided in the elevator car 21 that is the maintenance target device is received (step A11), the monitoring device 17 first reads the read signal. It is determined which two-dimensional code the signal corresponds to (step A12). This can be determined by checking whether or not the terminal ID of the maintenance staff 14 is added to the read signal.

  That is, when the maintenance staff 14 reads the first two-dimensional code 27 using the information transmitter 15, the terminal ID for identifying the information transmitter 15 is added to the read signal of the first two-dimensional code 27. And sent to the monitoring device 17. Therefore, if this terminal ID is added, it can be determined that the signal is a read signal of the first two-dimensional code 27.

  If it is the read signal of the first two-dimensional code 27 (Yes in Step A13), the monitoring device 17 refers to the maintenance DB 52a provided in the storage unit 52 (Step A14), and performs maintenance and inspection of the maintenance staff 14 Predetermined processing relating to work is performed (step A15).

  Specifically, first, a schedule screen 61 as shown in FIG. 11, for example, is displayed on the information transmitter 15 of the maintenance staff 14. On the schedule screen 61, a work schedule indicating the order of maintenance and inspection at each site, an address, and the like is described in a predetermined format. Note that the work schedule creation method and acquisition method are not directly related to the present invention, and thus the description thereof is omitted here.

  When the maintenance staff 14 visits the first site according to the work schedule, first, the start of work is notified to the monitoring center 16 using the information transmitter 15, and when the work is completed, the information transmitter 15 is used again. The work start is notified to the monitoring center 17.

  Here, the first two-dimensional code 27 provided at the site is used as means for notifying the start and end timing of the work at the site. As shown in FIG. 3, the first two-dimensional code 27 is provided in the switch box 25. When the maintenance staff 14 starts the work on the site and finishes the work, the first two-dimensional code 27 provided in the switch box 25 is read through the photographing unit 34 of the information transmitter 15.

  The first two-dimensional code 27 includes, for example, information on an on-site address and elevator, and the information is decoded in the information transmitter 15 and transmitted to the monitoring device 17 in the monitoring center 16. Is done. At this time, a unique terminal ID is simultaneously transmitted to the information transmitter 15. As a result, the information sent from which terminal at which site is specified, and the maintenance staff 14 who owns the terminal is specified by referring to the maintenance DB 52a.

  In the monitoring device 17, the first signal sent by reading the first two-dimensional code 27 provided at the site is “work start signal”, and the second signal sent is “work end signal”. " As a result, it is grasped which maintenance staff 14 is in what work situation at which site.

  In this case, when the monitoring device 17 recognizes that the maintenance worker 14 starts the inspection work by the “work start signal”, the work information indicating that the inspection work is started is given an ID for identifying the site. Is stored in the maintenance DB 52a. Further, when the monitoring device 17 recognizes that the maintenance staff 14 has finished the inspection work by the “work end signal”, the monitoring device 17 stores work information indicating that the inspection work at the site has been finished in the maintenance DB 52a. . Thereby, on the monitoring center 16 side, it is possible to manage the work status of the maintenance staff 14 at each site without particularly interposing an operator.

  On the other hand, when the read signal is the second two-dimensional code 28 (No in Step A13), the monitoring device 17 refers to the emergency call DB 52b provided in the storage unit 52 (Step A16). A predetermined process related to the emergency call of the passenger 18 is performed (step A17).

  Specifically, it is assumed that the passenger 18 is confined in the car 21 due to a wide-area disaster such as an earthquake. In the car 21, as shown in FIG. 2, the second two-dimensional code 28 is provided at a place where it can be easily seen. When the second two-dimensional code 28 is read using the imaging function provided in the communication terminal device 19 of the passenger 18, the two-dimensional code is decoded and emergency contact information obtained by the decoding process is obtained. Based on (access information), connection processing to the monitoring device 17 in the monitoring center 16 is executed.

  Specifically, the URL of the contact site provided by the monitoring center 16 is included in the second two-dimensional code 28 as the emergency contact information. When the second two-dimensional code 28 is read by the communication terminal device 19, an access request is issued from the communication terminal device 19 to the contact site according to the URL.

  At this time, for example, an access request screen 71 as shown in FIG. 12 is displayed, and a predetermined ID number is entered in the ID input field 72 provided on the access request screen 71, thereby preventing access other than the intended purpose. Anyway. However, the access request screen 71 for obtaining such an ID number is not necessarily indispensable, and the communication terminal device 19 can read the second two-dimensional code 28 and immediately connect to the contact site, that is, the monitoring center 16. It may be a mechanism.

  The monitoring device 17 in the monitoring center 16 receives the access request as an emergency call. Then, for example, based on the telephone number or mail address of the communication terminal device 19, the communication terminal device 19 is specified as the request source, and then guidance information for confirming the situation in the car room is transmitted. In this case, the second two-dimensional code 28 read by the communication terminal device 19 includes information such as the name and address of the building. The monitoring device 17 obtains such information from the communication terminal device 19 to search the emergency call DB 52b shown in FIG. 9 to determine an elevator property in an emergency state, and to provide guidance corresponding to the model of the elevator. Send screen data in which information is question-formatted.

  As in the example of FIG. 12, in the method for obtaining a predetermined ID number at the time of an access request, a response is made only when it is determined that the access request is from a legitimate user by a matching process using the ID number. Will do.

  The communication terminal device 19 displays the initial menu screen 81 as shown in FIG. 13 by receiving this screen data. This initial menu screen 81 is provided with a property item 82 including information such as a building name and elevator, an access item 83 including information such as a date of access to a contact site and a login time, and a failure communication item 84. Yes. This failure communication item 84 is an item for communicating the state of the car room in a question format by the selection operation of the passenger 18, and is an item for confirming the presence or absence of a confinement accident or a failure confirmation other than confinement. It has items such as. In the monitoring device 17, predetermined processing such as rescue processing is executed in accordance with the response of the passenger 18 to the failure communication item 84.

  The rescue process includes: (a) a warning that a confinement accident has occurred in the monitoring center 16 by a lamp display or the like and calling the operator; (b) a maintenance staff traveling around the property. And a rescue instruction is issued to the maintenance staff, and (c) a reset signal for releasing the door lock of the car 21 is output.

  As described above, according to the present system, two types of the first two-dimensional code 27 for maintenance personnel and the second two-dimensional code 28 for passengers are provided in the car 21, so In addition to the efficient management of the maintenance and inspection work of the maintenance staff 14, a quick response to the emergency call of the passenger 18 can be realized. As a result, even when a wide-area disaster such as an earthquake occurs, it is possible to respond quickly while grasping the work status of the maintenance staff 14 and to appropriately perform rescue operations for the passenger 18.

  Further, the first two-dimensional code 27 and the second two-dimensional code 28 are provided in a state of being distinguished from each other. In particular, the first two-dimensional code 27 is switched so that a person other than the maintenance staff 14 cannot use it. Isolated in box 25. Accordingly, it is possible to prevent a person other than the maintenance staff 14 from accessing the monitoring center 16 using the first two-dimensional code 27 without permission.

(Other embodiments)
In the embodiment described above, the first two-dimensional code 27 is provided in the switch box 25 to prevent use by anyone other than the maintenance staff 14, but the following method may be used.

(1) Using black light
As shown in FIG. 14, the black light 100 is used when reading the first two-dimensional code 27. The black light 100 is a lighting device that irradiates light of near ultraviolet light 101 of 300 to 450 nm, and here, for example, it is assumed that the maintenance staff 14 carries it. The first two-dimensional code 27 for maintenance personnel uses a fluorescent material that emits light by the near ultraviolet rays 101 emitted from the black light 100. Therefore, only the maintenance staff 14 can read using the black light 100.

  It is assumed that the photographing unit 34 of the information transmitter 15 possessed by the maintenance staff 14 has a sensitivity capable of photographing even in a state where the first two-dimensional code 27 emits light.

(2) Method of using elevator design
As shown in FIG. 15, a first two-dimensional code 27 for maintenance personnel is provided in a design 110 used on the wall surface of the car 21 and the like. In this case, the design 110 is preferably a design close to the monochrome pattern of the first two-dimensional code 27 shown in FIG.

  The maintenance staff 14 is informed of where the first two-dimensional code 27 is provided in the car 21 and can read it close to the place during maintenance inspection. It is not immediately known where it is located. Therefore, the use of the first two-dimensional code 27 by a person other than the maintenance staff 14 can be prevented.

(3) How to use the display
As shown in FIG. 16, a display 120 and a changeover switch 121 for displaying a two-dimensional code are installed in the car 21. The display 120 includes a small display device such as an LCD (Liquid Crystal Display), for example, and displays the first two-dimensional code 27 or the second two-dimensional code 28 by operating the changeover switch 121. In this case, in order to display the first two-dimensional code 27 when the operator of the changeover switch 121 is the maintenance staff 14, the following display changeover process is performed by the control device 122.

  FIG. 18 is a flowchart showing a two-dimensional code display switching process by the control device 122.

  Normally, the second two-dimensional code 28 for passengers is displayed on the screen of the display 120 (step B11). When the second two-dimensional code 28 is displayed and there is a switching instruction by operating the selector switch 121 (Yes in step B12), the controller 122 is that the operator at that time is the maintenance staff 14. Is determined (step B13). Specifically, for example, a password that only the maintenance staff 14 knows when operating the change-over switch 121 is determined to be the maintenance staff 14 when the password is correctly input.

  If it can be confirmed that it is the maintenance person 14 (Yes in Step B14), the control device 122 displays the first two-dimensional code 27 on the screen of the display 120 (Step B15). On the other hand, when it cannot be confirmed that the person is the maintenance person 14 (Yes in Step B14), the control device 122 prohibits the display of the first two-dimensional code 27 (Step B15). Thereby, persons other than the maintenance staff 14 can be prevented from using the first two-dimensional code 27.

  Here, the display is switched by a specific switch operation and password input. For example, when the maintenance staff 14 detects that the car 21 has entered the car 21, the first two-dimensional code 28 uses the first switch. You may make it switch to the two-dimensional code 27. FIG. As a detection method of the maintenance staff 14 in that case, for example, a specific radio wave is transmitted from the information transmitter 15 of the maintenance staff 14 and this is detected by a detector (not shown) installed in the car 21. There are methods.

  As described above, when the two types of the first two-dimensional code 27 and the second two-dimensional code 28 are provided, the first two-dimensional code 27 for maintenance personnel can be freely used by others. By taking measures that are not used, it is possible to prevent erroneous reporting to the monitoring center 16 and perform stable remote monitoring.

  In the above embodiment, emergency call processing is performed by reading the second two-dimensional code 28 for passengers. In addition, for example, some advertisement information or evacuation route information is provided to the passengers 18. It is also possible to do.

  Further, the information transmitter 15 possessed by the maintenance staff 14 is not limited to a mobile phone, and may be any terminal device provided that it has a two-dimensional code reading function. The same applies to the communication terminal device 19 possessed by the passenger 18.

  Further, the two-dimensional code is decoded in the information transmitter 15, but the photographed two-dimensional code image may be transmitted as it is to the monitoring device 17 and decoded on the monitoring device 17 side.

  The two-dimensional code may be the above-described QR code (registered trademark), PDF417, Maxi Code, Data Matrix, Veri Code, Code 49, Code 1, Aztec Code, RSS (Reads reduced Space Symbology), Super Code ( (Including registered trademarks).

  Furthermore, although the said embodiment demonstrated the example of the maintenance inspection work of the elevator, it can apply to the maintenance inspection work of not only an elevator but various apparatuses and articles | goods. Moreover, although the elevator was illustrated as an elevator, even if it is an escalator etc., the same effect can be expected.

  In short, the present invention is not limited to the above-described embodiments as they are, and can be embodied by modifying the components without departing from the scope of the invention in the implementation stage. Moreover, various forms can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment. For example, some components may be omitted from all the components shown in the embodiment. Furthermore, constituent elements over different embodiments may be appropriately combined.
