[0021] The embodiments for implementing this disclosure are described with reference to the accompanying drawings. Furthermore, in the drawings, identical or equivalent parts are labeled with the same reference numerals. Repetitive descriptions of these parts are appropriately simplified or omitted.

[0022] Implementation method 1.

[0023] Figure 1 This is a schematic diagram of the elevator system according to Implementation Method 1. Figure 2 This is a diagram showing the elevator car of Implementation Method 1 as viewed from a landing.

[0024] exist Figure 1 In the elevator system 1, the shaft 2 runs through all floors of the building 3. Multiple stations 4 are located on each floor of the building 3. Each of the multiple stations 4 is opposite to the shaft 2. An entrance / exit is provided between the station 4 and the shaft 2. Each of the multiple stations 4 has a station door 5 at its entrance / exit.

[0025] The traction machine 6 is located in a machine room above the hoistway 2. The main rope 7 is wound around the traction machine 6. The car 8 is suspended inside the hoistway 2 by the main rope 7. The car 8 can move up and down inside the hoistway 2 following the movement of the main rope 7 after the traction machine 6 has moved.

[0026] The car 8 has a car compartment 9. For example, the car compartment 9 is rectangular in shape and has multiple side walls 10. In this example, the multiple side walls 10 are composed of a door side wall 10a, a front wall 10b, a first side wall 10c, and a second side wall 10d. Furthermore, in Figure 1 The illustration of the second sidewall 10d is omitted.

[0027] The door side wall 10a is a side wall 10 adjacent to the landing 4. The door side wall 10a has an entrance / exit for the car 8 corresponding to the entrance / exit of the landing 4. The car 8 has a car door 11 on the door side wall 10a side.

[0028] The front wall 10b is opposite the door side wall 10a. For example... Figure 2 As shown, the front wall 10b is the side wall 10 located on the front when viewed from the landing 4 when the car 8 stops at the landing 4 and the car door 11 and landing door 5 are opened.

[0029] The first side wall 10c and the second side wall 10d are side walls 10 connecting the door side wall 10a and the front wall 10b. Figure 2 In the example shown, the first side wall 10c is a side wall 10 existing on the right side relative to the depth direction from the first side wall 10c towards the front wall 10b. The first side wall 10c is adjacent to the door side wall 10a and the front wall 10b, respectively. The second side wall 10d is a side wall 10 existing on the left side relative to the depth direction. The second side wall 10d is adjacent to the door side wall 10a and the front wall 10b, respectively.

[0030] The ceiling 10e forms the ceiling surface of the car compartment 9. The floor 10f forms the floor surface of the car compartment 9. Thus, the car compartment 9 is composed of multiple side walls 10, the ceiling 10e, and the floor 10f.

[0031] The elevator system 1 has a car control panel 12, a car camera 13, an alarm device 14, a front display 15, and a first display 16 inside the car compartment 9.

[0032] The car control panel 12 is located on the side of the entrance / exit of the car 8 on the door side wall 10a. The car control panel 12 is used by the user to call for the elevator to the next floor, i.e., to call the elevator from the car.

[0033] The car camera 13 is positioned at an angle that allows it to capture the interior of the car compartment 9. In this example of Embodiment 1, the car camera 13 is positioned at the upper part of the front wall 10b, at the center of the front wall 10b in the horizontal direction. The car camera 13 is configured at an angle that allows it to capture at least the entrance and exit of the car 8. The car camera 13 may also be positioned at an angle that allows it to capture a portion of the floor 10f. Furthermore, in this example, the car camera 13 may also be positioned on the ceiling 10e, provided that it can capture at least the entrance and exit of the car 8.

[0034] The announcer 14 is a device for announcing information. For example, the announcer 14 is a loudspeaker that emits sound. In addition, the announcer 14 may also include a display screen that displays information. For example, the announcer 14 is provided inside the car compartment 9 on the door side wall 10a.

[0035] The front display 15 is a device capable of displaying images on the front wall 10b. For example, the front display 15 is a liquid crystal display device disposed on the front wall 10b. Alternatively, the front display 15 can also be a projector that projects images. In this case, the front display 15 is disposed on the ceiling 10e and projects images onto the front wall 10b.

[0036] The first display 16 is a device capable of displaying images on either the first sidewall 10c or the second sidewall 10d. Hereinafter, an example of the first display 16 displaying an image on the first sidewall 10c will be described. For example, the first display 16 may be a liquid crystal display device disposed on the first sidewall 10c. Alternatively, the first display 16 may also be a projector that projects images. In this case, the first display 16 is disposed on the ceiling 10e and projects images onto the first sidewall 10c.

[0037] In elevator system 1, multiple landing beacons 17 are respectively installed at several of the multiple landings 4. The landing beacons 17 transmit radio waves containing an identifier specific to the car 8 and a floor-specific identifier for the landing 4. Furthermore, the landing beacons 17 can be installed at all of the landings 4, or only at specific landings 4 among the multiple landings 4.

[0038] The control device 20 is located in the machine room. The control device 20 is electrically connected to the traction machine 6, various equipment installed in the car 8, and other equipment in the elevator system 1. The control device 20 can control the overall operation of the car 8. The control device 20 can control the images displayed on the front display 15 and the first display 16.

[0039] The elevator system 1 also includes a server device 30 and a portable terminal 40. The server device 30 is located in a different building than the building 3. The server device 30 can communicate with the control device 20 via a network N.

[0040] For example, portable terminal 40 is a smartphone. Portable terminal 40 is held by a wheelchair user. Portable terminal 40 is able to communicate with server device 30 via network N. Portable terminal 40 stores specific applications that can be used in elevator system 1. Part of the functionality of portable terminal 40 is achieved by executing specific applications.

[0041] For example, a wheelchair user arrives at floor 4 on the 1st floor. A portable terminal 40 receives radio waves from a beacon 17 located on the 1st floor and initiates a specific application. The portable terminal 40 receives information from the wheelchair user regarding the next floor. The portable terminal 40 generates an elevator call request based on the received information and sends it to the server device 30. The elevator call request includes the identifier of the elevator car 8, the departure floor (the floor the wheelchair user entered), and the destination floor (the floor the user is going down to). The elevator call request also includes information indicating that the user is a wheelchair user.

[0042] Server device 30 receives an elevator call request and identifies the control device 20 corresponding to car 8. Server device 30 sends the elevator call request to control device 20. Control device 20 registers the elevator call request to car 8. Control device 20 moves car 8 toward the landing for wheelchair users. Before car 8 reaches the landing, control device 20 alerts notifier 14 to urge the clearing of space on the first side wall 10c where the image is displayed on the first display 16.

[0043] Then, the wheelchair user enters car 8. When car 8 stops at the next step for the wheelchair user, car camera 13 begins capturing images. Control device 20 displays the images captured by car camera 13 on front display 15 and first display 16. The user checks their surroundings by looking at the images displayed on front display 15 or first display 16 as they descend from car 8.

[0044] Next, use Figure 3 and Figure 4 The elevator system 1 will be described.

[0045] Figure 3 This is a functional block diagram of the elevator system in Implementation Method 1. Figure 4 This is a flowchart illustrating the operation overview of the elevator system in Implementation Method 1. Furthermore, in Figure 3 The illustrations of the traction machine 6, car 8, etc. are omitted in the text.

[0046] like Figure 3As shown, the portable terminal 40 includes a display unit 41, an operation unit 42, and a control unit 43. The display unit 41 displays information. For example, the display unit 41 is a monitor. The operation unit 42 receives user input. For example, the operation unit 42 is a button. Alternatively, a touchscreen display integrating the display unit 41 and the operation unit 42 can be provided on the portable terminal 40. The control unit 43 controls the overall operation of the portable terminal 40. Hereinafter, the operation of the portable terminal 40 will be described using a dedicated application. For example, the control unit 43 uses a specific application installed on the portable terminal 40 to display an operation interface on the display unit 41. Furthermore, the control unit 43 receives input to the operation interface via the operation unit 42.

[0047] Functionally, the server device 30 includes a storage unit 31 and a call control unit 32. The storage unit 31 stores setting information related to the elevator system 1, such as the elevator model 1, the structure of the building 3, the identifier of the car 8, and information about the side wall 10 displaying the image on the first display 16. The call control unit 32 sends a call request to the control device 20 based on a call request received from the portable terminal 40. Furthermore, the call control unit 32 can also send a call request with additional information attached to the call request received from the portable terminal 40 to the control device 20.

[0048] Functionally, the control device 20 includes an operation control unit 21, a display control unit 22, and a notification control unit 23. The operation control unit 21 controls the operation of the car 8. The display control unit 22 controls the processing of images displayed on the front display 15 and the first display 16. For example, the display control unit 22 acquires images captured by the car camera 13 and displays them on the front display 15 and the first display 16. The display control unit 22 can display the same image on the front display 15 and the first display 16, or it can display different images. The notification control unit 23 controls the content of the notification announced by the notification device 14.

[0049] Figure 4 The flowchart shown, for example, begins when a wheelchair user holding a portable terminal 40 approaches a certain floor station 4.

[0050] In step S01, the portable terminal 40 receives radio waves emitted by the layer station beacon 17. The portable terminal 40, triggered by receiving the layer station beacon 17, launches the dedicated application's user interface.

[0051] Then, the action of step S02 is performed. In step S02, the portable terminal 40 determines whether the car 8 indicated by the radio wave from the floor beacon 17 is registered in the portable terminal 40.

[0052] In step S02, if the portable terminal 40 does not register the car 8 indicated by the radio waves, the operation in step S03 is performed. In step S03, the portable terminal 40 sends a request to the server device 30 for setting information of the car 8 indicated by the radio waves from the floor beacon 17.

[0053] Then, in step S04, the server device 30 sends the setting information corresponding to the car 8 to the portable terminal 40 that received the request.

[0054] Then, in step S05, the portable terminal 40 receives setting information from the server device 30. The portable terminal 40 registers the setting information corresponding to the car 8 and the car 8.

[0055] After step S05 is performed, or if the car 8 shown in step S02 is registered with the portable terminal 40, step S06 is performed. In step S06, the portable terminal 40 receives input from the wheelchair user regarding the floor to be entered and the floor to be exited. Alternatively, the portable terminal 40 may also consider the floor shown by the landing beacon 17 as the floor to be entered, omitting the input of the floor to be entered.

[0056] Then, in step S07, the portable terminal 40 sends an elevator call request containing the entered floor number and floor number to the server device 30. This elevator call request includes information about the user being a wheelchair user. Alternatively, the floor number and floor number can be pre-registered in the portable terminal 40. In this case, after step S05, step S06 can be skipped, and step S07 can be performed based on the registered floor number and floor number.

[0057] Then, in step S08, the portable terminal 40 displays information about the side wall 10 on which the first display 16 shows the image, and information about the standby position of the floor 4 corresponding to the side wall 10, based on the setting information. Specifically, in this example, the portable terminal 40 displays information about the first display 16 being located on the first side wall 10c, and information indicating the standby position of the area on the floor 4 relative to the entrance / exit, closer to the first side wall 10c. Furthermore, the portable terminal 40 can also display information about the side wall 10 showing the image and the standby position information according to instructions from the server device 30.

[0058] Then, in step S09, the server device 30 receives an elevator call request from the portable terminal 40. The server device 30 then sends the elevator call request to the corresponding control device 20.

[0059] Then, in step S10, the control device 20 receives an elevator call request. The control device 20 registers the elevator call indicated in the call request to the car 8. The control device 20 initiates the action of moving the car 8 towards the floor of the registered elevator.

[0060] Then, in step S11, the control device 20 causes the alarm device 14 to notify the wheelchair user to take the elevator and to urge the space to be cleared on the side wall 10 where the image is displayed on the first display 16, i.e., in front of the side wall 10. Specifically, in this example, the control device 20 causes the alarm device 14 to notify the space to be cleared on the side of the first side wall 10c.

[0061] Then, in step S12, the control device 20 determines whether the car 8 has stopped at the floor indicated by the call button. If the car 8 has not yet stopped at the floor in step S12, the operation starting from step S11 is repeated. That is, the control device 20 continuously notifies the caller 14 from the moment the car 8 begins to move towards the floor until the car 8 stops at that floor.

[0062] If the car 8 stops at the boarding floor in step S12, then step S13 is performed. In step S13, the control device 20 opens the car door 11 of the car 8. The wheelchair user boards the car 8. Then, after closing the car door 11, the control device 20 moves the car 8 from the car 8 towards the next boarding floor. Furthermore, the control device 20 can also detect whether a wheelchair user has boarded the car 8 based on information obtained from the car camera 13, the weighing device of the car 8, etc.

[0063] Then, in step S14, the control device 20 determines whether the car 8 has stopped at the lower landing. If the car 8 has not stopped at the lower landing in step S14, the action of step S14 is repeated.

[0064] If the car 8 stops at the lower landing in step S14, the operation in step S15 is performed. In step S15, the control device 20 opens the car door 11. The control device 20 causes the front display 15 to display the image captured by the car camera 13. The control device 20 causes the first display 16 to display the image captured by the car camera 13. Here, if the first display 16 is a display device mounted on the first side wall 10c, the control device 20 controls the first display 16 to display the image, thereby causing the first display 16 to display the image captured by the car camera 13 on the first side wall 10c. By observing the images displayed on the front display 15 and the first display 16, the wheelchair user can check their rear and surroundings while descending the stairs from the car 8.

[0065] Then, in step S16, the control device 20 determines whether the car door 11 is closed. If the car door 11 is not closed in step S16, the operation starting from step S15 is repeated. Furthermore, in the repeated operation, the operation of the control device 20 opening the car door 11 is omitted.

[0066] If the car door 11 is closed in step S16, proceed to step S17. In step S17, the front display 15 and the first display 16 stop displaying the image from the car camera 13 based on the command from the control device 20. Then, the flowchart operation ends.

[0067] Furthermore, in step S02, the portable terminal 40 can also determine whether floor 4 has been registered instead of car 8. In this case, in step S04, the portable terminal 40 can also register the setting information corresponding to floor 4 and floor 4.

[0068] According to Embodiment 1 described above, the elevator system 1 includes a car 8, a car compartment 9, a car door 11, a car camera 13 serving as a camera, a first display 16 serving as a monitor, and a control device 20. The control device 20 causes the first display 16 to display the image captured by the car camera 13 on either a first side wall 10c or a second side wall 10d. Therefore, wheelchair users can view the image displayed on the first side wall 10c or the second side wall 10d, which is closer to the front display 15. As a result, wheelchair users can descend from the car 8 while viewing the image inside the car compartment 9.

[0069] In addition, the elevator system 1 also includes an alarm device 14. The control device 20 causes the alarm device 14 to alert and urge the clearing of space on the side of the first side wall 10c and the second side wall 10d where the first display 16 can display the image. Therefore, wheelchair users can ride in a position where they can easily see the image. Furthermore, in conventional technology where a mirror or display is provided on the front wall 10b, since a person stands between the mirror or display and the wheelchair user, it is sometimes difficult to see the image reflected on the mirror or display when the wheelchair user is getting off the elevator. In particular, ordinary passengers are sometimes unaware that the wheelchair user is using a mirror or the like to get off the elevator, so when the interior of the elevator car is crowded to a certain extent, it is difficult to ensure that there is no person between the front wall 10b and the wheelchair user. In this embodiment, the alarm device 14 is used to alert, thus preventing people riding in the elevator car 8 from standing between the wheelchair user and the image. In addition, when people riding in the elevator car 8 move to either side of the elevator car 9, it is easy to clear space where the image can be seen.

[0070] In addition, elevator system 1 also includes a server device 30. The server device 30 receives elevator call requests from the portable terminal 40 and sends them to the control device 20. The control device 20 registers the elevator call corresponding to the call request with the car 8. Since the floor the wheelchair user goes to and the floor they go to / away from corresponds to the elevator call request, the control device 20 performs actions to activate the alarm device 14 and to display an image on the first display 16. Since the wheelchair user sends the elevator call request from the portable terminal 40, the car 8 can be easily called. Furthermore, the wheelchair user can register the floor they go to / away from without using the car control panel 12. When the elevator call request includes a wheelchair user, for example, compared to a case where a wheelchair-bound floor call is made, the probability of a wheelchair user actually using the elevator is higher. Therefore, the control device 20 can efficiently and reliably improve convenience for wheelchair users.

[0071] Alternatively, the car camera 13 may not be located at the entrance or exit of the car 8, but may be configured to take a view of the floor 10f from an angle opposite to the floor 10f.

[0072] Furthermore, at least one of the front display 15 and the first display 16 can also display any image or video, such as an advertisement, when not displaying the image captured by the car camera 13. Additionally, the first display 16 can also be a touch display. In this case, the first display 16 can also display buttons for user input, such as the destination floor, when not displaying the image captured by the car camera 13.

[0073] Furthermore, the front display 15 may not be installed in the elevator system 1. For example, in elevators where the front wall 10b is clad in glass, installing the front display 15 may sometimes detract from the aesthetics. By displaying images on the first display 16, even without the front display 15, wheelchair users can review the images captured by the car camera 13 while descending the elevator.

[0074] Next, a first variation of the elevator system 1 according to Embodiment 1 will be described.

[0075] In the first variation, when the images from the car camera 13 are displayed on the front display 15 and the first display 16, that is, in Figure 4 In step S15 of the flowchart, the control device 20 sends information about the image captured by the car camera 13 to the server device 30 or directly to the portable terminal 40. At this time, the car 8 stops at the lower floor.

[0076] In step S15 of the flowchart, the portable terminal 40 displays the image captured by the car camera 13. Alternatively, the portable terminal 40 can also display the image based on instructions from the control device 20; that is, the control device 20 can also cause the portable terminal 40 to display the image.

[0077] For example, the portable terminal 40 displays the images captured by the car camera 13 until the car door 11 closes at the next landing.

[0078] According to the first variation of Embodiment 1 described above, when the car 8 stops at the lower landing, the image captured by the car camera 13 is displayed on the portable terminal 40. Therefore, wheelchair users can descend the stairs from the car 8 while checking their surroundings through a more easily viewable screen.

[0079] Next, use Figure 5 A second variation of the elevator system of Embodiment 1 will be described.

[0080] Figure 5 This is a schematic diagram of a variation of the elevator system in Implementation Method 1.

[0081] In the second variation, a landing control panel 18 for wheelchair users is provided at landing 4. The landing control panel 18 is located to the side of the landing door 5. The landing control panel 18 may also be explicitly marked as wheelchair-only. In the second variation, the control device 20 controls the alarm 14 in the same manner as in embodiment 1, not based on a call request from the portable terminal 40, but based on a landing call from the landing control panel 18.

[0082] The floor call button 18 sends a call to the control unit 20 indicating only the floor the user is on. This call button contains information indicating that the user is on the elevator.

[0083] When the control device 20 receives a call for elevator at that floor, it registers it with the car 8. During the period before the car 8 arrives at the floor, the control device 20 alerts the wheelchair user to board the elevator via the alarm device 14 and urges the side wall 10, where the image is displayed on the first display 16, to clear space.

[0084] After the elevator car 8 stops at the boarding floor, the car control panel 12 receives the input from the wheelchair user regarding the next floor. The control device 20 considers the next floor included in the car call received by the car control panel 12 during the boarding floor stop as the next floor for the wheelchair user. Then, the control device 20 performs... Figure 4 The flowchart shows the actions starting from step S15.

[0085] Alternatively, a car control panel for wheelchair users can be installed in the car 8. In this case, the control device 20 can also consider the lower floor included in the car call received by the car control panel for wheelchair users when the elevator stops at that floor as the lower floor for wheelchair users.

[0086] According to the second variation of Embodiment 1 described above, even when it is not a call for an elevator from the portable terminal 40, the control device 20 can improve the convenience for wheelchair users.

[0087] Implementation method 2.

[0088] Figure 6 This is a horizontal sectional view of the elevator car compartment of the elevator system in Embodiment 2. Furthermore, parts that are the same as or equivalent to those in Embodiment 1 are labeled with the same reference numerals. Descriptions of these parts are omitted.

[0089] like Figure 6 As shown, in Embodiment 2, a second display 50 is also provided in the car compartment 9. The second display 50 is a device capable of displaying images on the side wall 10 of the first side wall 10c and the second side wall 10d where the first display 16 is not provided. In this example, the first display 16 is a display device provided on the first side wall 10c. In this case, an example in which the second display 50 can display images on the second side wall 10d will be described below.

[0090] For example, the second display 50 is a liquid crystal display device, disposed on the second side wall 10d. Alternatively, the second display 50 can also be a projector that projects images. In this case, the second display 50 is disposed on the ceiling 10e and projects images onto the second side wall 10d. The control device 20, like the first display 16, is capable of controlling the information displayed on the second display 50. Specifically, the control device 20 can cause the second display 50 to display images captured by the car camera 13.

[0091] Although not illustrated, after receiving the landing beacon 17, the portable terminal 40 detects, based on setting information, that a first display 16 and a second display 50 are installed in the car 8. In this case, the portable terminal 40 accepts the wheelchair user's selection of which display to use from the first display 16 and the second display 50. Having accepted the selection from the wheelchair user, the portable terminal 40 sends an elevator call request containing selection information indicating which of the first display 16 and the second display 50 has been selected. The portable terminal 40 then sends the elevator call request containing the selection information to the server device 30.

[0092] Upon receiving an elevator call request containing selection information, the server device 30 causes the portable terminal 40 to display a standby position corresponding to one of the selection information shown in the first display 16 and the second display 50. This standby position is the location at the elevator landing 4. Specifically, if the second display 50 is shown in the selection information, information indicating the standby position at landing 4 on the side closer to the second side wall 10d relative to the entrance / exit is displayed.

[0093] The server device 30 sends the elevator call request to the corresponding control device 20. Before stopping at the elevator floor, the control device 20 causes the notifier 14 to notify and urge the space on the side wall 10 of one of the display images shown in the selection information of the first display 16 and the second display 50 to be cleared.

[0094] Then, after the elevator car 8 stops at the boarding floor and the wheelchair user enters the car 8, the control device 20 moves the car 8 to the lower floor. At this time, the wheelchair user enters the elevator with the side wall 10 in the open space. When the car 8 stops at the lower floor, the control device 20 displays the image captured by the car camera 13 on one of the selection information shown on the first display 16 and the second display 50.

[0095] According to Embodiment 2 described above, the elevator system 1 also includes a second display 50. The portable terminal 40 accepts a selection from either the first display 16 or the second display 50 and generates selection information. The control device 20 causes the display showing the selection information to display the image from the car camera 13. Therefore, the image can be displayed on the side wall 10, which is convenient for wheelchair users.

[0096] Furthermore, the control device 20 prompts the notifier 14 to urge the space on the side wall 10 where the selected information is displayed on the screen to be cleared. Therefore, even when a first display 16 and a second display 50 are provided as two displays, the control device 20 can always notify the notifier to clear the space on the appropriate side.

[0097] Furthermore, the portable terminal 40 displays a standby position corresponding to the display showing the selection information. Therefore, wheelchair users can easily board the elevator car 8. Additionally, in Embodiment 1, even when the standby position corresponding to the first display 16 is displayed, wheelchair users can still easily board the elevator car 8.

[0098] Implementation method 3.

[0099] Figure 7 This is a schematic diagram of the elevator system according to Embodiment 3. Furthermore, parts that are the same as or equivalent to those in Embodiment 1 or 2 are labeled with the same reference numerals. Descriptions of these parts are omitted.

[0100] like Figure 7 As shown, in embodiment 3, the elevator system 1 also includes a landing camera 51. For example, landing cameras 51 are installed at multiple landings 4. Alternatively, the landing cameras 51 may be installed only at specific landings 4 among the multiple landings 4.

[0101] The landing camera 51 is positioned above the entrance / exit between landing 4 and car 8, specifically above landing door 5. The landing camera 51 is positioned at an angle that allows it to capture the surrounding area of ​​the entrance / exit at landing 4.

[0102] The car camera 13 is positioned at an angle capable of capturing images of the car door 11. In this case, when the car 8 stops at a certain floor 4 and the car door 11 is open, the car camera 13 can capture images of the floor 4 through the entrance / exit of the car 8.

[0103] Control device 20 Figure 7 The display control unit 22 (not shown) generates a composite image by combining the images captured by the landing camera 51 and the car camera 13. The composite image is created by linking the images of both the landing camera 51 and the car camera 13 using a common reference position. A bird's-eye view of the interior of the car 9 and a bird's-eye view of the area near the entrance / exit of the landing 4 are combined and displayed in the composite image.

[0104] When the car 8 stops at the lower landing, the control device 20 causes one of the selection information shown in the first display 16 and the second display 50 and the front display 15 to display a composite image.

[0105] According to Embodiment 3 described above, the elevator system 1 also includes a landing camera 51. The control device 20 generates a composite image. The composite image is displayed on the first display 16. Therefore, wheelchair users can descend the elevator while viewing an image that also takes into account the condition of the landing 4. As a result, the safety of wheelchair users can be further improved.

[0106] Furthermore, the composite image can be displayed on the portable terminal 40 when the car 8 stops at the lower landing. Therefore, wheelchair users can view the image on a more easily accessible screen. Additionally, after at least part of the wheelchair has descended to landing 4, the surrounding area can also be assessed.

[0107] Furthermore, the elevator system 1 shown in embodiments 1 to 3 can also be applied to any type of elevator, such as elevators without a machine room. For example, elevator system 1 can also be applied to through-floor elevators where the car 8 has two or more car doors 11. In this case, the front display 15 may not be required. Even in through-floor elevators, by installing a display on the side wall 10 where the car doors 11 are not located, wheelchair users can confirm safety while descending from the car 8.

[0108] Next, use Figure 8 An example of the hardware constituting the server device 30 will be described.

[0109] Figure 8This is a hardware structure diagram of the server device for the elevator system in embodiments 1 to 3.

[0110] The functions of the server device 30 can be implemented by processing circuitry. For example, the processing circuitry includes at least one processor 100a and at least one memory 100b. For example, the processing circuitry includes at least one dedicated hardware 200.

[0111] When the processing circuitry includes at least one processor 100a and at least one memory 100b, the functions of the server device 30 are implemented by software, firmware, or a combination of software and firmware. At least one of the software and firmware is described as a program. At least one of the software and firmware is stored in at least one memory 100b. At least one processor 100a implements the functions of the server device 30 by reading and executing the program stored in at least one memory 100b.

[0112] When the processing circuitry has at least one dedicated hardware 200, the processing circuitry may be implemented by, for example, a single circuit, a composite circuit, a programmable processor, a parallel programmable processor, an ASIC, an FPGA, or a combination thereof. For example, each function of the server device 30 may be implemented separately by the processing circuitry. Alternatively, each function of the server device 30 may be implemented uniformly by the processing circuitry.

[0113] Regarding the various functions of the server device 30, some can be implemented by dedicated hardware 200, and others by software or firmware. For example, the functions of the storage unit 31 can be implemented by processing circuitry as dedicated hardware 200, and functions other than those of the storage unit 31 can be implemented by at least one processor 100a reading and executing programs stored in at least one memory 100b.

[0114] In this way, the processing circuitry implements the various functions of the server device 30 through hardware 200, software, firmware, or a combination thereof.

[0115] Furthermore, server device 30 can also be implemented on a cloud server. In this case, the processing circuitry consists of multiple circuit components. These multiple processing circuit components are respectively located in multiple devices constituting the cloud server. The multiple devices constituting the cloud server can also be located in different buildings.

[0116] Although not shown, the functions of the control device 20 and the portable terminal 40 are implemented by the same processing circuits that implement the functions of the server device 30.
