[0022] The mode for implementing the present disclosure is described with reference to the accompanying drawings. In addition, in each figure, the same reference numerals are given to the same or corresponding parts. The repeated description of the parts is appropriately simplified or omitted.

[0023] Implementation Method 1

[0024] Figure 1 This is a schematic diagram of a building in which the elevator system in Embodiment 1 is installed.

[0025] exist Figure 1 In the elevator system 1, a hoistway 2 passes through each floor of a building 3. A machine room 4 is provided just above the hoistway 2. A plurality of landing stations 5 are provided on each floor of the building 3. The plurality of landing stations 5 are respectively opposite to the hoistway 2. A traction machine 6 is provided in the machine room 4. A main rope 7 is wound around the traction machine 6. A car 8 is suspended on one side of the main rope 7 inside the hoistway 2. A counterweight 9 is suspended on the other side of the main rope 7 inside the hoistway 2.

[0026] A plurality of landing doors 10 are respectively provided at the entrances and exits of a plurality of landings 5. A plurality of collecting devices 11 are provided at a plurality of landings 5. For example, each of the plurality of collecting devices 11 is a camera. For example, the collecting device 11 is provided at the upper portion of the landing door 10. The collecting device 11 collects information of users existing in the provided landing 5. Specifically, the collecting device 11 captures an image of the landing 5, thereby collecting information on the appearance of the user. The collecting device 11 transmits the collected information.

[0027] The car door 12 is provided at the entrance and exit of the car 8. The first car operating device 13 is provided inside the car 8. The first car operating device 13 can receive the destination floor of the car 8. The second car operating device 14 is provided inside the car 8 at a location different from the first car operating device 13. The second car operating device 14 can receive the destination floor of the car 8. The releaser 15 is provided adjacent to the second car operating device 14. For example, the releaser 15 is a switch.

[0028] The control panel 16 is installed in the machine room 4. The control panel 16 can control the entire elevator system 1. The control panel 16 is electrically connected to the traction machine 6 and the collection device 11. The control panel 16 is electrically connected to the car door 12, the first car operating device 13, the second car operating device 14 and the releaser 15 via control cables (not shown).

[0029] When the elevator system 1 is in normal operation, for example, a user riding in the car 8 operates the first car operating device 13 to input a destination floor. The control panel 16 registers the call of the input destination floor in the car 8. The control panel 16 closes the car door 12 in an open state. At this time, the landing door 10 is closed together with the car door 12. The control panel 16 rotates the traction machine 6. The main rope 7 moves following the rotation of the traction machine 6. The car 8 and the counterweight 9 rise and fall in opposite directions following the movement of the main rope 7. After the car 8 reaches the destination floor, the control panel 16 opens the car door 12. The control panel 16 operates the car 8 until the call registered in the car 8 disappears, that is, until all the calls registered in the car 8 are completed.

[0030] The second car operating device 14 is an operating device for a wheelchair user, i.e., a wheelchair user, to input a destination floor. When the second car operating device 14 is operated, the control panel 16 performs wheelchair-only operation of the car 8. In the wheelchair-only operation, operation is performed in consideration of the wheelchair user. For example, in the wheelchair-only operation, the car door 12 is open for a longer time than the car door 12 is open in normal operation. For example, in the wheelchair-only operation, the car door 12 is closed at a slower speed than the car door 12 is closed in normal operation. For example, in the wheelchair-only operation, the acceleration of the car 8 at the time of departure and arrival is smaller than the acceleration of the car 8 at the time of departure and arrival in normal operation. The wheelchair-only operation continues until departure from the destination floor accepted by the second car operating device 14, and then ends.

[0031] Next, use Figure 2 and Figure 3 The first car operating device 13 and the second car operating device 14 will be described.

[0032] Figure 2 This is a perspective view showing the interior of a car of the elevator system in the first embodiment. Figure 3 This is a schematic diagram of a cross section of a car of the elevator system in the first embodiment.

[0033] like Figure 2 and Figure 3 As shown, the first car operating device 13 is provided on the side of the car door 12. For example, the first car operating device 13 has a mechanical button indicating a destination floor.

[0034] The second car operating device 14 is provided on a side of the car 8 different from the car door 12. For example, the second car operating device 14 is a touch panel type operating device. The second car operating device 14 displays a button indicating a destination floor on an operation screen. The wheelchair user operates the second car operating device 14 by touching the position of the button displayed on the operation screen.

[0035] Next, use Figure 4 The second car operating device 14 and the control panel 16 will be further described.

[0036] Figure 4 This is a block diagram of the elevator system in the first embodiment.

[0037] like Figure 4 As shown, the second car operating device 14 includes a display unit 14a and an operation receiving unit 14b.

[0038] The display unit 14a is a touch panel display. The display unit 14a displays either an operation screen or a standby screen. The operation screen is a screen in which operations such as inputting a destination floor can be performed. The operation screen displays buttons for operation, numbers indicating the current floor, etc. Specifically, the standby screen is a screen in which operations such as inputting a destination floor cannot be performed, and is a screen indicating that the operation cannot be performed. In addition, the standby screen is a screen that does not indicate that it is operated by a general user. Specifically, the standby screen is a screen that displays information indicating that it is a standby screen, and a number indicating that the operation cannot be performed. Figure 4 The same pattern, news information, Figure 4 The information screen of the guide information and advertisement information inside the building 3 not shown in the figure is not the information screen of the operation screen. In addition, the standby screen may be a completely black screen or a screen where the display disappears. When the display unit 14a receives an instruction related to the display content from the control panel 16, it displays the screen indicated by the instruction.

[0039] The operation receiving unit 14b is a sensor of the touch panel. The operation receiving unit 14b detects the position touched by the user on the touch panel. The operation receiving unit 14b detects the button operated on the operation screen based on the position. The operation receiving unit 14b sends the information indicated by the operated button to the control panel 16 as information such as the destination floor. The information sent by the operation receiving unit 14b includes information indicating that the destination floor has been operated by the second car operating device 14.

[0040] The releaser 15 has a release switch. When the release switch is operated, the releaser 15 assumes that the release operation has been performed and transmits a release signal to the control panel 16. Although not shown, the releaser 15 may include a message to urge the wheelchair user to operate the release switch.

[0041] The control panel 16 includes an operation control unit 16a, a detection unit 16b, and a display instruction unit 16c.

[0042] The operation control unit 16a controls the operation of the car 8 as a whole. Specifically, the operation control unit 16a generates a call based on the information of the destination floor received from the first car operating device 13 or the second car operating device 14, and registers it in the car 8. The operation control unit 16a uses the call registered in the car 8 to move the car 8. The operation control unit 16a controls the opening and closing of the car door 12. When the operation control unit 16a receives information indicating that the second car operating device 14 has been operated, it performs wheelchair-specific operation.

[0043] The detection unit 16b detects the presence of a wheelchair user at the landing 5 based on the information received from the collection device 11. Specifically, when the collection device 11 is a camera and an image of the landing 5 is received from the collection device 11, the detection unit 16b detects that a wheelchair is captured in the image using image recognition technology. In this case, the detection unit 16b detects the presence of a wheelchair user at the landing 5 corresponding to the captured image.

[0044] The display command unit 16c generates a command for the display content of the second car operating device 14 and transmits it to the second car operating device 14. During normal operation, when a wheelchair user is not detected at the landing 5, the display command unit 16c generates a command to display a standby screen and transmits it. When a wheelchair user is detected at any of the plurality of landings 5, and the car 8 opens the car door 12 at the landing 5, the display command unit 16c generates a command to display an operation screen and transmits it.

[0045] When the call registered in the car 8 disappears while the second car operating device 14 is displaying the operation screen, the display command unit 16c generates and transmits a command to display the standby screen. When the second car operating device 14 receives a release signal from the release device 15 while the working screen is displayed, the display command unit 16c generates and transmits a command to display the operation screen.

[0046] Next, use Figures 5 to 8 The operation of the elevator system 1 will be described.

[0047] Figure 5 This is a diagram showing a first example of the operation of the elevator system in the first embodiment. Figure 6 This is a diagram showing a first example of the operation of the elevator system in the first embodiment. Figure 7 This is a diagram showing a second example of the operation of the elevator system in the first embodiment. Figure 8 1 is a flowchart for explaining the outline of the operation of the elevator system in Embodiment 1. Figure 5 to Figure 7 The control panel 16 is not shown in the figure.

[0048] like Figure 5 As shown in the first example, the collection device 11 on a certain floor captures a wheelchair user who is waiting in front of the landing door 10 at the landing 5. The control panel 16 detects that the wheelchair user is at the landing 5.

[0049] The car 8 arrives at the landing 5. Figure 5 In this state, the second car operating device 14 displays a standby screen indicated by oblique lines according to a command from the control panel 16. That is, the second car operating device 14 is in an inoperable state.

[0050] Then, if Figure 6 As shown, the car door 12 is opened. At this time, the control panel 16 sends a command to display the operation screen to the second car operating device 14. When receiving the command, the operation screen is displayed in the second car operating device 14. That is, the second car operating device 14 becomes operable.

[0051] Although not shown in the figure, the operation screen is operated by the wheelchair user afterwards. In the elevator system 1, wheelchair-only operation is performed. When all the calls registered in the car 8 are completed and the calls registered in the car 8 disappear, the control panel 16 sends a command to display the standby screen to the second car operating device 14. When receiving the command, the standby screen is displayed in the second car operating device 14 instead of the operation screen. Then, before other commands are sent from the control panel 16, the standby screen is displayed in the second car operating device 14. That is, the second car operating device 14 becomes inoperable.

[0052] like Figure 7 As shown in the second example, the collection device 11 on a certain floor takes a picture of a user who is not a wheelchair user at the landing 5. The control panel 16 does not detect the presence of a wheelchair user at the landing 5. In this case, even if the car door 12 is opened at the landing 5, the standby screen continues to be displayed in the second car operating device 14. That is, the second car operating device 14 becomes inoperable. The user does not consider operating the standby screen. The user operates the first car operating device 13 to input the destination floor.

[0053] In the second example, when the release device 15 is operated at an arbitrary timing, the operation screen is also displayed in the second car operating device 14 according to the command from the control panel 16. For example, even if the wheelchair user is present at the landing 5 but the control panel 16 does not detect the presence of the wheelchair user, the wheelchair user can use the operation screen by operating the release device 15.

[0054] Figure 8 The flowchart of , for example, starts when the elevator system 1 is started.

[0055] In step S1, the control panel 16 sends a command to display a standby screen. The second car operating device 14 displays the standby screen.

[0056] Then, when the release switch 15 is not operated in step S2 , the operation of step S3 is performed. In step S3 , the control panel 16 determines whether a wheelchair user is detected at any landing 5 .

[0057] If the wheelchair user is not detected in step S3, the operations after step S1 are performed.

[0058] When a wheelchair user is detected in step S3, the operation of step S4 is performed. In step S4, the control panel 16 determines whether the car door 12 is opened at the landing 5 where the wheelchair user is detected.

[0059] When the car door 12 is not opened at the landing 5 in step S4, the operations after step S1 are performed.

[0060] When the car door 12 is opened at the landing 5 in step S4, the operation of step S5 is performed. In step S5, the control panel 16 sends a command to display the operation screen. The second car operating device 14 displays the operation screen. At this time, the call input through the operation screen can also be registered in the car 8.

[0061] Then, in step S6 , the car 8 is operated. Specifically, the control panel 16 moves the car 8 to the destination floor of the call registered in the car 8 .

[0062] Then, in step S7, the control panel 16 determines whether there is a call registered in the car 8.

[0063] When there is a call registered in the car 8 in step S7, the operations in step S6 and subsequent steps are performed.

[0064] If there is no call registered in the car 8 in step S7, the operations after step S1 are performed. That is, the second car operating device 14 changes the display from the operation screen to the standby screen.

[0065] When the releaser 15 is operated in step S2, the operations in step S5 and subsequent steps are performed.

[0066] In addition, in the present embodiment, the detection unit 16b and the display command unit 16c may be provided in a device other than the control panel 16. For example, the detection unit 16b and the display command unit 16c may be provided in the second car operating device 14. In this case, information required for the operation of the detection unit 16b and the display command unit 16c may be sent from each device to the second car operating device 14 as the device.

[0067] According to the first embodiment described above, the elevator system 1 includes a car 8, a collecting device 11, a first car operating device 13, and a second car operating device 14. When the presence of a wheelchair user is detected at the landing 5, the second car operating device 14 becomes operable. When the wheelchair user operates the second car operating device 14, the car 8 performs wheelchair-only operation. However, in the wheelchair-only operation, the movement of the car 8 takes longer time than the normal operation. When there is no wheelchair user at the landing 5, the second car operating device 14 becomes inoperable. In this case, a user who is not a wheelchair user will not operate the second car operating device 14, and therefore, the wheelchair-only operation is not performed. That is, it is possible to suppress the situation where the wheelchair user does not take the elevator but the wheelchair-only operation is performed. As a result, it is possible to suppress the reduction in operating efficiency.

[0068] Furthermore, the second car operating device 14 displays the operation screen, thereby being in an operable state, and does not display the operation screen, thereby being in an inoperable state. In particular, the second car operating device 14 displays a standby screen instead of the operation screen. Therefore, the second car operating device 14 does not make the user who is not a wheelchair user aware that the second car operating device 14 is to be operated. As a result, the dissatisfaction of the user who cannot operate the second car operating device 14 can be reduced.

[0069] Furthermore, the second car operating device 14 is a touch panel, so that an operable state and an inoperable state can be easily switched.

[0070] In addition, the second car operating device 14 may not be a touch panel type device, but an operating device using projection. In this case, the second car operating device 14 may not be set on the side of the interior of the car 8. For example, the display unit 14a may also be a projector that projects the operation screen and the standby screen onto the side of the interior of the car 8. The operation receiving unit 14b may also be a sensor that detects the presence of an object such as a human hand at the position of a button on the projected operation screen. In this case, the operation receiving unit 14b may also detect the position of the object, thereby detecting the operated button. The operation screen is in a state where the user can operate it. The standby screen is in a state where the user cannot operate it. Therefore, in the case where the second car operating device 14 is an operating device using projection, it is also possible to easily switch between an operable state and an inoperable state.

[0071] Furthermore, when the car door 12 is opened at the landing 5 where a wheelchair user is detected, the second car operating device 14 changes from an inoperable state to an operable state. Therefore, it is possible to prevent the second car operating device 14 from being operated by a user who is not a wheelchair user before arriving at the landing 5.

[0072] Furthermore, when the elevator call registered in the car 8 disappears, the second car operating device 14 changes from an operable state to an inoperable state. When the elevator call registered in the car 8 disappears, it is assumed that there is no wheelchair user in the car 8. That is, in this case, it is not necessary to operate the second car operating device 14. Therefore, it is possible to suppress unnecessary operation of the second car operating device 14.

[0073] In addition, the elevator system 1 further includes a releaser 15. When the releaser 15 is released, the second car operating device 14 becomes operable. Therefore, for example, when a wheelchair user is not correctly detected due to a malfunction of the collecting device 11 or the detecting unit 16b, the wheelchair user can operate the second car operating device 14 by performing the release operation.

[0074] In addition, the control panel 16 may generate a command to display the standby screen when it detects that the second car operating device 14 is operated, not when the elevator call registered in the car 8 disappears, and transmit the command to the second car operating device 14. In addition, the control panel 16 may generate a command to display the standby screen when the wheelchair-only operation ends, and transmit the command to the second car operating device 14. In this case, unnecessary operation of the second car operating device 14 can be suppressed.

[0075] In addition, the collection device 11 can collect information that shows that the user is a wheelchair user, and it does not need to be a camera. Specifically, the collection device 11 can also be a card reader that collects information from an ID card indicating that the user is a wheelchair user. For example, the collection device 11 can also be a floor station operation panel dedicated to wheelchair users installed in the floor station 5. In any case, the detection unit 16b detects the presence of a wheelchair user in the floor station 5 based on the received information.

[0076] In addition, the release operation of the release device 15 may not be an operation of a switch but may be an arbitrary operation, etc. In the release device 15, the release operation may be performed by a predetermined release key.

[0077] Next, use Fig. 9 An example of hardware constituting the control board 16 will be described.

[0078] Fig. 9 This is a hardware configuration diagram of the control panel of the elevator system in the first embodiment.

[0079] Each function of the control panel 16 can be realized by a processing circuit. For example, the processing circuit has at least one processor 100a and at least one memory 100b. For example, the processing circuit has at least one dedicated hardware 200.

[0080] In the case where the processing circuit has at least one processor 100a and at least one memory 100b, the functions of the control panel 16 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 reads out and executes the program stored in at least one memory 100b, thereby implementing the functions of the control panel 16. At least one processor 100a is also called a central processing unit, a processing unit, an arithmetic unit, a microprocessor, a microcomputer, and a DSP. For example, at least one memory 100b is a non-volatile or volatile semiconductor memory such as RAM, ROM, flash memory, EPROM, EEPROM, a magnetic disk, a floppy disk, an optical disk, a high-density disk, a mini disk, a DVD, etc.

[0081] In the case where the processing circuit has at least one dedicated hardware 200, the processing circuit is implemented, for example, by a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination thereof. For example, each function of the control panel 16 is implemented by the processing circuit separately. For example, each function of the control panel 16 is implemented uniformly by the processing circuit.

[0082] The functions of the control panel 16 may be partially implemented by the dedicated hardware 200, and the other part may be implemented by software or firmware. For example, the function of detecting a wheelchair user using the information from the collection device 11 may be implemented by the processing circuit of the dedicated hardware 200, and the functions other than the function of detecting a wheelchair user using the information from the collection device 11 may be implemented by at least one processor 100a reading and executing a program stored in at least one memory 100b.

[0083] In this way, the processing circuit implements the functions of the control panel 16 through hardware 200, software, firmware or a combination thereof.

[0084] Although not shown in the drawings, each function of the second car operating device 14 is also realized by a processing circuit similar to the processing circuit that realizes each function of the control panel 16 .
