[0013] [Embodiment 1] An embodiment of the present invention will be described in detail below. Fig. 1 is a block diagram showing an example of the configuration of an elevator system 100 according to the first embodiment of the present invention. The elevator system 100 is a system that operates elevators based on destination floor registration. As shown in Fig. 1, the elevator system 100 includes a group management control device 2, an elevator control device 3, an elevator 4, an authentication device 5 (authentication unit), a reading device 6, and a display system 200.

[0014] In elevator system 100, each floor of a building is preset as either a registerable floor that can be registered as a destination floor or a restricted floor where destination floor calls are restricted. When a user is authenticated by authentication device 5, registration of a destination floor call with a restricted floor as the destination floor is permitted. The following describes an example in which elevator 4 is installed in a building with floors from the third basement floor to the sixteenth floor, and the third basement floor, the seventh to ninth floors, and the fourteenth and fifteenth floors are restricted floors.

[0015] The display system 200 is a system that performs display related to destination floor registration and authentication. As an example, the display system 200 includes a destination floor registration device 1. The display system 200 displays a numeric keypad 302 including buttons (numeric buttons 301) each associated with a single-digit number on the display unit 13. The display system 200 also accepts one or more operations on the numeric buttons 301 as an input operation for the destination floor.

[0016] Furthermore, at each stage where the input operation for a destination floor can be accepted, if the floor whose ones digit corresponds to the number associated with the operated number button 301 is a restricted floor, the display system 200 changes the display mode of the number button 301 from the display mode of the number buttons 301 other than the number button 301. The display mode of the number button 301 corresponding to the number corresponding to the restricted floor is referred to as the first display mode. The first display mode is a display mode that includes restricted floor information indicating that the corresponding floor is a restricted floor. The display mode of the number buttons 301 other than the number button 301 corresponding to the number corresponding to the restricted floor is referred to as the second display mode. The second display mode is a display mode that does not include restricted floor information.

[0017] According to this configuration, a user of the elevator 4 can know whether or not the floor corresponding to each number button 301 is a restricted floor, simply by looking at the screen on which the number buttons 301 are displayed.

[0018] <Group management control device 2> The group management control device 2 registers a destination floor call based on a call request for a destination floor call from the destination floor registration device 1. When the group management control device 2 receives a call request including information indicating the departure floor and the destination floor from the destination floor registration device 1, it assigns the most appropriate elevator 4 based on the call request and the operation status of the elevators 4.

[0019] The group management control device 2 transmits the allocation result information to the destination floor registration device 1, which is the sender of the call request. The group management control device 2 also transmits information indicating the departure floor and destination floor based on the registered destination floor call to the elevator control device 3, which controls the elevator assigned to the destination floor call.

[0020] <Elevator control device 3 and elevator 4> The elevator control device 3 controls the operation of the elevators 4 based on information received from the group control device 2. The elevator control device 3 also transmits information indicating the operation status of the elevators 4 to the group control device 2. The elevators 4 move between floors and open and close their doors based on the control of the elevator control device 3. A single building may be provided with multiple elevators 4 and multiple elevator control devices 3 that control each elevator 4.

[0021] <Reading device 6 and authentication device 5> The reading device 6 and the authentication device 5 are devices for authenticating users.

[0022] The reading device 6 is a device that reads information for authenticating a user. For example, when authentication is performed using a card, the reading device 6 may be a card reader or the like that can read identification information, etc., attached to a card held by the user. The reading device 6 reads the information attached to a card held over the reading device 6 and transmits the read information to the authentication device 5 as user information about the user. Note that the authentication method is not limited to a method using a card, and may be authentication using biometric information such as face, fingerprint, or vein information. In this case, the reading device 6 may be a device that can acquire the biometric information of the user. The reading device 6 may be provided near the destination floor registration device 1. As an example, the reading device 6 may be configured as a device integrated with the destination floor registration device 1.

[0023] The authentication device 5 authenticates the user based on the user information read by the reading device 6. The authentication device 5 may be, for example, a cloud server or the like, and is communicably connected to the reading device 6 and the destination floor registration device 1. The authentication device 5 includes a control unit 51 and a storage unit 52.

[0024] The storage unit 52 stores registration information 521. The registration information 521 is information for authenticating users, and stores, for each registrant, identification information for identifying the registrant who is permitted to access the restricted floor. When the authentication method is authentication using biometric information, the registration information 521 stores the identification information of the registrant in association with the biometric information of the registrant.

[0025] The control unit 51 authenticates the user based on the information read by the reading device 6. Specifically, when the control unit 51 receives the user information read by the reading device 6 from the reading device 6, the control unit 51 refers to the registration information 521. If the user information matches the identification information or biometric information of any registered person included in the registration information 521, the control unit 51 determines that the authentication of the user has been successful. On the other hand, if the received information is not included in the registration information 521, the control unit 51 determines that the authentication of the user has failed. The control unit 51 transmits information indicating whether the authentication of the user has been successful to the destination floor registration device 1 corresponding to the reading device 6.

[0026] <Destination Floor Registration Device 1> The destination floor registration device 1 is a device that registers a destination floor call based on an input operation by a user. Only one destination floor registration device 1 may be provided in a building, or multiple destination floor registration devices 1 may be provided. One destination floor registration device 1 may be provided on each floor of a building. Furthermore, multiple destination floor registration devices 1 may be provided on one floor of a building.

[0027] 1, the destination floor registration device 1 includes a control unit 11, an input unit 12, a display unit 13, and a storage unit 14. The destination floor registration device 1 is also connected to an authentication device 5 and a group management control device 2 so as to be able to communicate with each other.

[0028] The input unit 12 accepts an input operation by a user and outputs a signal indicating the content of the accepted input operation to the control unit 11. The display unit 13 displays a predetermined screen under the control of a display control unit 113 (described later) of the control unit 11. The input unit 12 and the display unit 13 may be an integrated device or may be separate devices. In the following example, a configuration in which the input unit 12 and the display unit 13 are an integrated device such as a touch panel will be described.

[0029] The storage unit 14 stores various information used in the destination floor registration device 1. As shown in FIG. 1, the storage unit 14 stores authentication result information 141, destination floor information 142, and floor information 143. The authentication result information 141 is information indicating whether or not the user has been authenticated by the authentication device 5. The destination floor information 142 is information for identifying the destination floor of the user when making a call request, and is information indicating the numbers entered by the user.

[0030] Fig. 2 is a diagram showing an example of floor information 143. Floor information 143 is information indicating floors existing in a building. As shown in Fig. 2, floor information 143 associates information indicating each floor existing in a building with either information indicating that the floor is a registerable floor or information indicating that the floor is a restricted floor.

[0031] The control unit 11 includes an operation receiving unit 111 , an update unit 112 , a display control unit 113 , and a registration unit 114 .

[0032] (Operation reception unit 111) The operation reception unit 111 receives an input operation from a user to the input unit 12. The operation reception unit 111 can receive an input operation corresponding to a predetermined stage at that stage. In this embodiment, the stages at which the operation reception unit 111 can receive an operation include, for example, a first stage and a second stage.

[0033] Furthermore, the operation receiving unit 111 may be capable of receiving an operation on the basement floor button 303 in either the first stage or the second stage. Hereinafter, an operation on the basement floor button 303 will be referred to as a "basement floor input operation." Hereinafter, any floor not described as a "basement floor" or "basement X floor" will refer to a ground floor.

[0034] The first stage is a stage in which the operation acceptance unit 111 can accept the first operation on the numeric buttons 301. Hereinafter, an operation on the numeric buttons 301 that the operation acceptance unit 111 can accept in the first stage, i.e., the first operation on the numeric buttons 301 in a series of call registrations, will be referred to as a "first numeric input operation." The period in which no operation has been performed on the numeric buttons 301 in a series of call registrations corresponds to the first stage. When the processing related to the registration of the previous destination floor call is completed, a first screen (described below) is displayed on the display unit 13 under the control of the display control unit 113. When the first screen is displayed, the operation acceptance unit 111 becomes able to accept the first numeric input operation or the basement floor input operation. The first stage is the period from when the first screen is displayed until the operation acceptance unit 111 accepts the first numeric input operation or the basement floor input operation. When the operation acceptance unit 111 accepts the first numeric input operation in the first stage, a second screen is displayed under the control of the display control unit 113. When the second screen is displayed, the system transitions to the second stage.

[0035] The second stage is a stage after the first stage in a series of call registrations, and is a stage in which the operation acceptance unit 111 can accept a second operation on the numeric buttons 301. When a first numeric input operation is performed in the first stage, a second screen (described later) is displayed on the display unit 13 under the control of the display control unit 113. When the second screen is displayed, the operation acceptance unit 111 can accept a second numeric input operation or a basement floor input operation. The second stage corresponds to the period from when the second screen is displayed until a predetermined time has elapsed, or until either a second operation on the numeric buttons 301 or a basement floor input operation is accepted. The predetermined time may be, for example, two seconds. Hereinafter, an operation on the numeric buttons 301 that the operation acceptance unit 111 can accept in the second stage, i.e., a second input operation on the numeric buttons 301 in a series of call registrations, is referred to as a "second numeric input operation." In the second stage, if the operation reception unit 111 receives the second number input operation or the basement floor input operation, or if the first number input operation is not received until a predetermined time has elapsed, the destination floor in the destination floor call is identified.

[0036] If the building has a basement floor, the operation reception unit 111 can receive a basement floor input operation in the first stage or the second stage. In this case, the stages at which the operation reception unit 111 can receive an operation include a third stage in addition to the first and second stages. When the operation reception unit 111 receives a basement floor input operation in the first stage, the operation transitions to the third stage.

[0037] The third stage is a stage after the first stage, and is a stage at which the first operation on the numeric button 301 can be accepted. When a basement floor input operation is performed in a series of call registrations, a third screen (described later) is displayed on the display unit 13 under the control of the display control unit 113. When the third screen is displayed, the operation acceptance unit 111 is able to accept a first numeric input operation. The third stage corresponds to the period from when the third screen is displayed until a predetermined time has elapsed or until an operation on the numeric button 301 is accepted. When the operation acceptance unit 111 accepts the first numeric input operation in the third stage, the destination floor in the destination floor call is identified. Furthermore, when the operation acceptance unit 111 does not accept the first numeric input operation until the predetermined time has elapsed in the third stage, acceptance of the destination floor call in the destination floor call is canceled.

[0038] In the first stage, the operation reception unit 111 waits for reception of a first number input operation or a basement floor input operation. In the second stage, the operation reception unit 111 waits for reception of a second number input operation or a basement floor input operation. In the third stage, the operation reception unit 111 waits for reception of a first number input operation. If the operation reception unit 111 does not receive a predetermined input operation for a predetermined time in the second and third stages, it cancels the state of waiting for reception of various input operations and returns to the first stage.

[0039] (Updated part 112) The update unit 112 acquires various pieces of information from the authentication device 5, the group management control device 2, and the operation reception unit 111, and updates the storage unit 14 based on the acquired information.

[0040] When the update unit 112 receives information indicating whether or not the authentication of the user has been successful from the authentication device 5, the update unit 112 stores the received information in the storage unit 14 as authentication result information 141.

[0041] Furthermore, the update unit 112 updates the destination floor information 142 based on the input operation accepted by the operation acceptance unit 111. When the operation acceptance unit 111 accepts a first numeric input operation in the first stage, the update unit 112 acquires information indicating the input numeric value from the operation acceptance unit 111. The update unit 112 stores the information in the storage unit 14 as destination floor information 142, and updates the destination floor information 142. When the operation acceptance unit 111 accepts a second numeric value input operation in the second stage, the update unit 112 acquires information indicating the input numeric value from the operation acceptance unit 111. The update unit 112 stores the information in the storage unit 14 as destination floor information 142, and updates the destination floor information 142.

[0042] When the operation receiving unit 111 receives a basement floor input operation in the first stage or the second stage, the update unit 112 acquires information indicating that information indicating a basement floor has been input in the first stage from the operation receiving unit 111. The update unit 112 stores the information in the storage unit 14 as destination floor information 142 and updates the destination floor information 142.

[0043] When the registration unit 114 makes a destination floor call, the destination floor registration device 1 receives allocation result information from the group management control device 2. When the update unit 112 receives the allocation result information, it deletes the destination floor information 142.

[0044] (Display control unit 113) Display control unit 113 controls the display on display unit 13. FIGS. 3 to 5 are diagrams showing examples of screens displayed by display unit 13. FIG. 3 is a diagram showing an example of a first screen displayed by display unit 13 in a first stage. FIG. 4 is a diagram showing an example of a second screen displayed by display unit 13 in a second stage. FIG. 5 is a diagram showing an example of a third screen displayed by display unit 13 in a third stage. Display control unit 113 causes display unit 13 to display the first screen in the first stage, the second screen in the second stage, and the third screen in the third stage.

[0045] 3 to 5, the display control unit 113 causes the display unit 13 to display a numeric keypad 302 including number buttons 301 each associated with a single-digit number. Each of the number buttons 301 is associated with a number from 0 to 9. If the building only has single-digit floors, the display control unit 113 may not display unnecessary number buttons 301, for example, number buttons 301 associated with numbers corresponding to floors that do not exist in the building.

[0046] If the building has a basement floor, numeric keypad 302 includes basement floor button 303, which is a button for specifying the basement floor as the destination floor, as shown in Figures 3 to 5. Furthermore, if an evacuation floor is set in the building, numeric keypad 302 further includes evacuation floor button 304, which is a button associated with the floor indicating the evacuation floor, as shown in Figures 3 to 5.

[0047] Furthermore, the display control unit 113 determines the display mode of each numeric button 301 based on the relationship between the number indicated by the numeric button 301 and the restricted floor. In each stage (first to third stages) at which the operation receiving unit 111 can receive operations, if the floor whose ones digit is the number associated with the operated numeric button 301 corresponds to the restricted floor, the display control unit 113 makes the display mode of the numeric button 301 different from the display modes of the numeric buttons 301 other than the operated numeric button 301.

[0048] When the restricted floor is a one-digit floor, the display control unit 113 displays, in the first stage, the number button 301 associated with the number corresponding to the restricted floor in the first display mode (symbol Q), and displays the number buttons 301 other than the number button 301 in the second display mode (symbol P). When the restricted floor is a two-digit floor, the display control unit 113 displays, in the second stage, the number button 301 associated with the number corresponding to the ones digit of the two-digit restricted floor in the first display mode, and displays the number buttons 301 other than the number button 301 in the second display mode.

[0049] The display control of the display unit 13 by the display control unit 113 will be described in detail below. After the process related to the registration of the previous destination floor call is completed, the display control unit 113 refers to the floor information 143 and identifies a floor that corresponds to a restricted floor among the single-digit floors. When the display control unit 113 identifies a single-digit restricted floor, it causes the first screen to be displayed on the display unit 13. The period from when the first screen is displayed until the first number input operation is performed corresponds to the first stage.

[0050] As shown in FIG. 3, the first screen includes number buttons 301, a basement floor button 303, and an evacuation floor button 304. The first screen may also include a message prompting the user to input a destination floor. As shown in FIG. 2, in this embodiment, the restricted floors among the single-digit floors of the building are floors 7 to 9. Therefore, the display control unit 113 displays, among the number buttons 301 on the first screen, number buttons 301 corresponding to the numbers 7 to 9 in a first display mode (symbol Q). Furthermore, the display control unit 113 displays, among the number buttons 301 on the first screen, number buttons 301 corresponding to the numbers 0 to 6 in a second display mode (symbol P). With the above configuration, the user can know which floors among the single-digit floors are restricted before performing the first button operation (first number input operation).

[0051] The first display mode differs from the second display mode in at least one of the information superimposed on the numeric buttons 301, the color of the numeric buttons 301, the appearance of the numeric buttons 301, and the size of the numeric buttons 301. The first display mode may be a display mode that enables the user to understand that the floor indicated by the number corresponding to the numeric button 301 displayed in the first display mode, or a floor that includes that number in the ones digit, is a restricted floor.

[0052] The first display mode includes restricted floor information indicating that the floor corresponding to the number indicated by the numeric button 301 displayed in the first display mode is a restricted floor. As an example, a symbol such as a square may be superimposed on the numeric button 301 (symbol Q) displayed in the first display mode, as shown in Fig. 3. According to the above configuration, the user can know the restricted floor simply by checking the numeric button 301.

[0053] When the operation receiving unit 111 receives the first number input operation in the first stage, the display control unit 113 refers to the floor information 143 and identifies the two-digit restricted floor. When the display control unit 113 identifies the two-digit restricted floor, it causes the display unit 13 to display the second screen. The period from when the second screen is displayed until the operation receiving unit 111 receives the second number input operation corresponds to the second stage.

[0054] As shown in Fig. 4, the second screen includes information (symbol 401) indicating the number entered in the first stage, numeric buttons 301, a basement button 303, and an evacuation floor button 304. As shown in Fig. 2, in this embodiment, the restricted floors among the two-digit floors of the building are the 14th and 15th floors. Therefore, as shown in Fig. 4, the display control unit 113 displays the numeric buttons 301 corresponding to the numbers 4 and 5 in the first display mode (symbol Q) on the second screen. Furthermore, in the second stage, the display control unit 113 displays the numeric buttons 301 corresponding to the numbers 0 to 3 and 6 to 9 in the second display mode (symbol P).

[0055] According to the above configuration, the user can know which of the two-digit floors is a restricted floor after performing the first button operation (first number input operation) and before performing the second button operation (second number input operation).

[0056] When the operation reception unit 111 receives a basement floor input operation in the first stage, the display control unit 113 refers to the floor information 143 and identifies the restricted single-digit basement floor. When the display control unit 113 identifies the restricted single-digit basement floor, it causes the display unit 13 to display a third screen. The period from when the third screen is displayed until the operation reception unit 111 receives a first number input operation corresponds to the third stage.

[0057] 5, the third screen includes input information (reference numeral 501) including characters indicating the basement floor, numeric buttons 301, a basement floor button 303, and an evacuation floor button 304. When the operation receiving unit 111 receives a basement floor input operation, if the basement floor having the number associated with the numeric button 301 as its ones digit corresponds to a restricted floor, the display control unit 113 displays the numeric button 301 in the first display mode. In addition, the display control unit 113 displays the numeric buttons 301 other than the numeric button 301 in the second display mode.

[0058] As shown in Fig. 2, in this embodiment, the restricted basement floor of the building is the third basement floor. Therefore, as shown in Fig. 5, in the third stage, the display control unit 113 displays the numeric button 301 corresponding to the number 3 in the first display mode (symbol Q). In addition, in the second stage, the display control unit 113 displays the numeric buttons 301 corresponding to the numbers 0 to 2 and 4 to 9 in the second display mode (symbol P).

[0059] According to the above configuration, the user can know which of the basement floors is a restricted floor after performing an operation on the basement floor button 303 indicating the basement floor (basement floor input operation) and before performing an operation on the number button 301 indicating the number.

[0060] In the past, in buildings where elevators that operate based on destination floor calls are installed, there are cases where restricted floors are set to restrict destination floor calls. With conventional numeric keypad displays, elevator users cannot know whether the floor they plan to input is a restricted floor before performing the input operation, and they only find out that the floor is a restricted floor after inputting the floor, which can be inconvenient.

[0061] In contrast, with the configuration according to the present invention, the display control unit 113 causes the display unit 13 to display numeric buttons 301 for which the associated number in the ones digit corresponds to a restricted floor in a different display mode from the display modes of numeric buttons 301 other than the associated number 301. This allows the user to know whether the floor for which the number in the ones digit associated with the numeric button 301 in question is a restricted floor before operating the numeric button 301. This reduces the possibility of a situation occurring in which an unauthenticated user inputs a certain floor as a destination floor without knowing that it is a restricted floor, resulting in the destination floor call being rejected. As described above, the configuration according to the present invention can improve convenience for users who input destination floors.

[0062] In addition, the display control unit 113 changes the display mode of the numeric button 301 depending on whether or not the floor whose ones digit is the number associated with the operated numeric button 301 exists in the building in which the elevator 4 is installed, at each stage (first stage, second stage, and third stage) at which the operation receiving unit 111 can receive operations.

[0063] If a floor whose ones digit is the number associated with numeric button 301 exists in the building where elevator 4 is installed, display control unit 113 displays numeric button 301 in the first display mode or the second display mode. On the other hand, if a floor whose ones digit is the number associated with numeric button 301 does not exist in the building where elevator 4 is installed, display control unit 113 displays numeric button 301 in the third display mode. The third display mode is a display mode that includes information indicating that a floor whose ones digit is the number associated with numeric button 301 displayed in the third display mode does not exist in the building where elevator 4 is installed. With the above configuration, users can distinguish between floors that exist in the building and floors that do not exist.

[0064] FIG. 6 is a diagram showing an example of the second screen including a display in the third display mode. When number button 301 indicating 1 is pressed in the first stage, floors that can be specified as the destination floor are the first floor or a floor with 1 in the tens digit. Here, of the floors with 1 in the tens digit, floors 10 to 16 exist in the building, but floors 17 to 19 do not exist in the building. Numeric keypad 302 includes number buttons 301 indicating 0 to 9, but there are no floors in the building that have the numbers associated with number buttons 301 indicating 7 to 9 in the ones digit. In this case, as shown in FIG. 6, display control unit 113 displays number buttons 301 indicating 0 to 6 in the first display mode or the second display mode, and displays number buttons 301 indicating 7 to 9 in the third display mode.

[0065] As shown in Fig. 6, the third display mode may be a display mode in which diagonal lines are superimposed on the numeric buttons 301 as information indicating that the elevator 4 does not exist in the building where the elevator 4 is installed, but is not limited to this. The third display mode may be any display mode that allows a user to understand that a floor having the ones digit associated with the numeric button 301 displayed in the third display mode does not exist in the building where the elevator 4 is installed. For example, the display control unit 113 may gray out the numeric buttons 301 displayed in the third display mode. Furthermore, the operation accepting unit 111 may not accept an input operation on the numeric buttons 301 displayed in the third display mode.

[0066] When the registration unit 114 completes the registration of the destination floor call, the display control unit 113 acquires allocation result information from the group management control device 2. Upon acquiring the allocation result information, the display control unit 113 causes the display unit 13 to display an allocation result screen.

[0067] 7 is a diagram showing an example of an allocation result screen. As shown in FIG. 7, the allocation result screen includes information (reference numeral 701) indicating the elevator number of the elevator 4 assigned to the destination floor call and information (reference numeral 702) indicating the destination floor. This allows the user to know the elevator number that the user should board. The display control unit 113 displays the allocation result screen for a predetermined time (for example, 2 seconds) and then displays the first screen on the display unit 13.

[0068] Furthermore, the display control unit 113 may cause an error screen to be displayed on the display unit 13. For example, if the user is not authenticated by the authentication device 5, the destination floor registration device 1 receives authentication result information 141 indicating that the user has not been authenticated. If the authentication result information 141 indicating that the user has not been authenticated is received, the display control unit 113 may cause the display unit 13 to display an error screen including a message indicating that the user has not been authenticated. This allows the user to understand that authentication using the reading device 6 has failed.

[0069] Furthermore, if a user enters a floor that cannot be specified as a destination floor, or if an unauthorized user specifies a restricted floor as a destination floor, the display control unit 113 may display an error screen on the display unit 13. When the display control unit 113 acquires information indicating that registration of a destination floor call has been rejected from the registration unit 114, it displays an error screen on the display unit 13 that includes a symbol or a message indicating that the destination floor call having the floor entered by the user as the destination floor has been rejected. This allows the user to understand that they were unable to register a destination floor call having the floor they entered as the destination floor. The display control unit 113 displays the error screen on the display unit 13 for a predetermined time, and then displays the screen that was previously displayed again.

[0070] The display mode of the screen that the display control unit 113 causes the display unit 13 to display is not limited to the one described above. Fig. 8 is a diagram showing another example of the first screen. As shown in Fig. 8, the display control unit 113 may cause a specific symbol (symbol 801) to be displayed on the numeric button 301 that is the target to be displayed in the first display mode (symbol Q).

[0071] Fig. 9 is a diagram showing another example of the second screen. As shown in Fig. 9, the display control unit 113 may display the numbers displayed on the number buttons 301, which are the targets of display in the first display mode (symbol Q), surrounded by a frame (symbol 901). The display control unit 113 may also display a message (symbol 902) indicating which floors are restricted floors. Furthermore, the display control unit 113 may display information indicating the input numbers surrounded by a frame (symbol 903).

[0072] (Registration Section 114) The registration unit 114 registers the destination floor call of the destination floor accepted by the operation acceptance unit 111. When the operation acceptance unit 111 accepts the first number input operation in the first stage, a single-digit number is stored in the destination floor information 142. The registration unit 114 determines whether or not the operation acceptance unit 111 has accepted the second number input operation in the second stage.

[0073] If the operation receiving unit 111 does not receive the second number input operation in the second stage, the registration unit 114 identifies, as the destination floor, a single-digit floor including a number corresponding to the input number button 301. Specifically, the registration unit 114 identifies, as the destination floor, a single-digit floor indicated by a number stored as the destination floor information 142.

[0074] When operation receiving unit 111 receives the second number input operation in the second stage, registration unit 114 identifies, as the destination floor, a two-digit floor including the number corresponding to number button 301 that was input, that is, a two-digit floor indicated by the number stored as destination floor information 142. Specifically, registration unit 114 identifies, as the destination floor, a two-digit floor including, as the tens digit, the number corresponding to number button 301 that was input in the first number input operation, and as the ones digit, the number corresponding to number button 301 that was input in the second number input operation.

[0075] Furthermore, when the operation receiving unit 111 receives the first number input operation and the basement floor input operation, the registration unit 114 identifies, as the destination floor, a single-digit basement floor including the number corresponding to the input number button 301. Specifically, the registration unit 114 identifies, as the destination floor, a single-digit basement floor indicated by the number stored as the destination floor information 142.

[0076] After identifying the destination floor, the registration unit 114 transmits information to the group management control device 2 requesting the provision of service floor information indicating the service floor, and receives the service floor information from the group management control device 2. A service floor is a floor at which any of the elevators 4 can stop. Based on the service floor information, the registration unit 114 determines whether the identified destination floor is a service floor of the elevator 4. If the identified destination floor is not a service floor of the elevator 4, the registration unit 114 rejects the registration of the destination floor call.

[0077] If the identified destination floor is a service floor of elevator 4, registration unit 114 refers to floor information 143 and determines whether the identified destination floor is a restricted floor. If the identified destination floor is not a restricted floor, registration unit 114 permits registration of the destination floor call.

[0078] If the identified destination floor is a restricted floor, the registration unit 114 determines whether the user has been authenticated by referring to the authentication result information 141. If the user has been authenticated, the registration unit 114 permits the registration of a destination floor call with the restricted floor as the destination floor, and if the user has not been authenticated, the registration unit 114 denies the registration of a destination floor call with the restricted floor as the destination floor.

[0079] A case in which the user has been authenticated refers to a case in which the authentication result information 141 indicates that the authentication of the user has been successful. In this case, the registration unit 114 permits the registration of a destination floor call with the restricted floor as the destination floor. When the registration unit 114 permits the registration of the destination floor call, it transmits a call request to the group management control device 2, the call request including information indicating the departure floor, which is the floor on which the destination floor registration device 1 is installed, and information indicating the identified destination floor. As a result, the destination floor call is registered in the group management control device 2, and the optimal elevator is assigned to the destination floor call.

[0080] A case where the user is not authenticated occurs when authentication result information 141 indicates that authentication of the user has failed, or when authentication result information 141 is not stored in storage unit 14. In this case, registration unit 114 refuses to register a destination floor call that has a restricted floor as the destination floor. When registration unit 114 refuses to register a destination floor call, it outputs information indicating that registration of the destination floor call has been refused to display control unit 113.

[0081] According to the above configuration, if a user is a registered user who is permitted to access a restricted floor, they can register a destination floor call specifying the restricted floor as the destination floor by performing authentication. On the other hand, if a user who is not permitted to access a restricted floor makes a destination floor call specifying the restricted floor as the destination floor, the user is not authenticated, and therefore the destination floor call is not registered. This reduces the possibility that an unauthorized user will mistakenly go to a restricted floor.

[0082] <Processing flow performed by elevator system 100> The flow of processing performed by the elevator system 100 will be described below with reference to Figures 10 to 12. Figures 10 to 12 are flowcharts or sequence diagrams for explaining the flow of processing performed by the elevator system 100.

[0083] (Authentication processing) First, the flow of processing related to authentication performed by the elevator system 100 will be described with reference to Fig. 10. Fig. 10 is a sequence diagram showing an example of the flow of processing related to authentication performed by the elevator system 100.

[0084] When a user performs authentication, the user has the reading device 6 read the user information. When the authentication device 5 acquires the user information read by the reading device 6 (YES in S1), it refers to the registration information 521 and determines whether the user information matches any of the registration information 521 (S2).

[0085] If the user information matches any of the registered information 521 (YES in S2), the control unit 51 determines that the authentication of the user has been successful (S3). On the other hand, if the user information does not match any of the registered information 521 (NO in S2), the control unit 51 determines that the authentication of the user has failed (S4). The control unit 51 transmits information indicating the authentication result to the destination floor registration device 1 (S5).

[0086] When the update unit 112 of the destination floor registration device 1 receives the information indicating the authentication result (YES in S11), it stores the received information in the storage unit 14 as authentication result information 141 (S12).

[0087] If the authentication result indicated by authentication result information 141 indicates that the user has been authenticated (YES in S13), display control unit 113 causes display unit 13 to display an authentication success screen indicating that authentication has been successful (S14). On the other hand, if the authentication result indicated by authentication result information 141 indicates that the user has not been authenticated (NO in S13), display control unit 113 causes display unit 13 to display an authentication failure screen indicating that authentication has failed (S15). After S14 or S15, display control unit 113 causes display unit 13 to redisplay the screen that was displayed immediately before displaying the authentication success screen or authentication failure screen (S16).

[0088] Thereafter, when the registration of the destination floor call is completed (YES in S17), or when a predetermined time has elapsed since the authentication result information 141 was stored (YES in S18), the update unit 112 deletes the authentication result information 141 (S19). This makes it possible to prevent the authentication result of the first user from being used when a second user registers a destination floor call after the first user who performed authentication.

[0089] (Screen display and call registration processing) Next, a process flow related to screen display and call registration performed by the elevator system 100 will be described with reference to Fig. 11 and Fig. 12. Fig. 11 and Fig. 12 are a flowchart and a sequence diagram showing an example of a process flow related to screen display and call registration performed by the destination floor registration device 1 of the elevator system 100.

[0090] FIG. 11 is a flowchart showing an example of the flow of processing performed by the destination floor registration device 1 regarding screen display and destination floor identification based on a user's input operation. First, the display control unit 113 refers to the floor information 143 and identifies a single-digit restricted floor (S21). Next, the display control unit 113 causes the display unit 13 to display a first screen (S22: display control step). Here, the display control unit 113 changes the display mode of the number buttons 301 indicating the numbers corresponding to each floor based on whether or not a floor provided in the building is a restricted floor. Specifically, the display control unit 113 displays the number buttons 301 associated with the single-digit numbers corresponding to the restricted floors in a first display mode, and displays the other number buttons 301 in a second display mode.

[0091] When the display control unit 113 causes the display unit 13 to display the first screen, the operation acceptance unit 111 becomes able to accept a first number input operation or a basement floor input operation. This starts the first stage. In the first stage, when the operation acceptance unit 111 accepts the first number input operation (YES in S23: operation acceptance step), the operation acceptance unit 111 stores information indicating the input number as destination floor information 142 in the storage unit 14. Furthermore, when the operation acceptance unit 111 accepts the first number input operation, it stops accepting input operations. This ends the first stage.

[0092] Furthermore, in the first stage, when the operation reception unit 111 receives a first number input operation (YES in S23: operation reception step), the display control unit 113 refers to the floor information 143 and identifies the two-digit restricted floor (S24). Next, the display control unit 113 displays a second screen on the display unit 13 (S25: display control step). Here, the display control unit 113 changes the display mode of the number buttons 301 indicating the numbers corresponding to each floor based on whether or not a floor provided in the building is a restricted floor. Specifically, the display control unit 113 displays the number buttons 301 associated with the number corresponding to the ones digit of the two-digit restricted floor in a first display mode, and displays the other number buttons 301 in a second display mode.

[0093] When the display control unit 113 displays the second screen on the display unit 13, the operation acceptance unit 111 becomes able to accept the second number input operation. This starts the second stage. In the second stage, when the operation acceptance unit 111 accepts the second number input operation (YES in S26: operation acceptance step), the operation acceptance unit 111 stores information indicating the input number as destination floor information 142 in the storage unit 14. Furthermore, when the operation acceptance unit 111 accepts the second number input operation, it stops accepting the input operation. This ends the second stage.

[0094] If the answer is YES in S26, the registration unit 114 identifies the destination floor based on the destination floor information 142 (S29). In this case, the registration unit 114 identifies, as the destination floor, the floor indicated by the number in which the number input by the first number input operation is the tens digit and the number input by the second number input operation is the ones digit.

[0095] Furthermore, in the second stage, if the operation acceptance unit 111 does not accept the second number input operation (NO in S26) but accepts a basement floor input operation (YES in S27: operation acceptance step), the operation acceptance unit 111 stores information indicating that a basement floor has been input as destination floor information 142 in the storage unit 14. Furthermore, upon accepting the basement floor input operation, the operation acceptance unit 111 stops accepting input operations. This ends the second stage.

[0096] If the answer is YES in S27, the registration unit 114 identifies the destination floor based on the destination floor information 142 (S29). In this case, the registration unit 114 identifies the basement floor, which has the number input by the first number input operation as the ones digit, as the destination floor.

[0097] Furthermore, in the second stage, if the operation acceptance unit 111 does not accept either the second number input operation or the basement floor input operation (NO in S26 and S27) and a predetermined time has elapsed since the display control unit 113 caused the second screen to be displayed on the display unit 13 (YES in S28), the operation acceptance unit 111 stops accepting the input operation. This ends the second stage.

[0098] If the answer is YES in S28, the registration unit 114 identifies the destination floor based on the destination floor information 142 (S29). In this case, the registration unit 114 identifies the floor indicated by the number input by the first number input operation as the destination floor.

[0099] In the first stage, if the operation acceptance unit 111 does not accept the first numeral input operation (NO in S23) but accepts a basement floor input operation (YES in S30: operation acceptance step), the operation acceptance unit 111 stores information indicating that information indicating a basement floor has been input as destination floor information 142 in the storage unit 14. Furthermore, upon accepting the basement floor input operation, the operation acceptance unit 111 stops accepting input operations. Furthermore, if YES in S30, the display control unit 113 identifies a single-digit basement floor as a restricted floor (S31).

[0100] Next, the display control unit 113 displays the third screen on the display unit 13 (S32: display control step). Here, the display control unit 113 changes the display mode of the numeric buttons 301 indicating the numbers corresponding to each floor based on whether or not a basement floor provided in the building is a restricted floor. Specifically, the display control unit 113 displays the numeric buttons 301 associated with the numbers corresponding to the restricted floors among the single-digit basement floors in the first display mode, and displays the other numeric buttons 301 in the second display mode.

[0101] When the display control unit 113 causes the third screen to be displayed on the display unit 13, the operation acceptance unit 111 becomes able to accept the first number input operation. This starts the third stage. In the third stage, when the operation acceptance unit 111 accepts the first number input operation (YES in S33: operation acceptance step), the operation acceptance unit 111 stores information indicating the input number as destination floor information 142 in the storage unit 14. Furthermore, when the operation acceptance unit 111 accepts the first number input operation, it stops accepting input operations. This ends the third stage.

[0102] If the result of S33 is YES, the registration unit 114 identifies the destination floor based on the destination floor information 142 (S29). In this case, the registration unit 114 identifies the basement floor, which has the number entered by the first number input operation as the ones digit, as the destination floor. After S29, the process proceeds to the process shown in FIG.

[0103] On the other hand, in the third stage, if the operation acceptance unit 111 does not accept the first number input operation (NO in S33) and a predetermined time has elapsed since the display control unit 113 displayed the third screen on the display unit 13 (YES in S34), the operation acceptance unit 111 stops accepting input operations. This ends the third stage, and the process of S21 is performed again. Also, if neither the first number input operation nor the basement floor input operation is accepted in the first stage (NO in S23 and S30), the process of S21 is performed again.

[0104] Next, the processing performed after the destination floor is identified (after the processing of S29 in Fig. 11) will be described with reference to Fig. 12. Fig. 12 is a sequence diagram showing the flow of processing performed by the elevator system 100 after the destination floor is identified.

[0105] When the registration unit 114 identifies the destination floor, it transmits a service floor provision request to the group management control device 2 (S41). When the group management control device 2 receives the service floor provision request (YES in S51), it transmits service floor information to the destination floor registration device 1, which is the sender of the service floor provision request. When the registration unit 114 receives the service floor information, it determines whether the identified destination floor is a service floor based on the received service floor information (S42).

[0106] If the destination floor is a service floor (YES in S42), the registration unit 114 determines whether the destination floor is a restricted floor (S43). If the destination floor is not a restricted floor (NO in S43), the registration unit 114 permits the registration of the destination floor call.

[0107] On the other hand, if the destination floor is a restricted floor (YES in S43), the registration unit 114 refers to the authentication result information 141 in the storage unit 14 and determines whether the user has been authenticated (S44). If the user has been authenticated (YES in S44), the registration unit 114 permits the registration of the destination floor call.

[0108] When the registration unit 114 permits the registration of the destination floor call, it registers the destination floor call. Specifically, the registration unit 114 generates a call request including information indicating the departure floor, which is the floor on which the destination floor registration device 1 is installed, and information indicating the identified destination floor. Next, the registration unit 114 transmits the generated call request to the group management control device 2 (S45).

[0109] When the group management control device 2 receives a call request (S52), it assigns the elevator 4 number that is most suitable for the received call request (S53) and registers the destination floor call. After assigning the elevator number, the group management control device 2 transmits assignment result information that includes information indicating the assigned elevator number and information indicating the destination floor. The group management control device 2 also transmits information indicating the departure floor and destination floor to the elevator control device 3 that controls the assigned elevator.

[0110] When the display control unit 113 receives the allocation result information from the group management control device 2 (YES in S46), it causes the display unit 13 to display an allocation result screen including the allocation result information (S47). When a predetermined time has elapsed since the allocation result screen was displayed (YES in S48), the display control unit 113 ends the screen display.

[0111] If the destination floor is not a service floor (NO in S42), or if the destination floor is a restricted floor (YES in S43), and the user has not been authenticated (NO in S44), the registration unit 114 refuses to register the destination floor call. The case where the user has not been authenticated occurs when the authentication result information 141 indicates that the user has not been authenticated, or when the authentication result information 141 is not stored in the storage unit 14.

[0112] If the registration unit 114 rejects the registration of the destination floor call, the display control unit 113 causes the display unit 13 to display an error screen including information indicating that the destination floor call could not be registered (S49). When a predetermined time has elapsed since the error screen was displayed (YES in S48), the display control unit 113 ends the screen display.

[0113] After the screen display is terminated, the process returns to the processing of S21 shown in Fig. 11. As a result, after the allocation result screen or error screen is displayed, the first screen is displayed, and it becomes possible to register the next destination floor call.

[0114] [Embodiment 2] Other embodiments of the present invention will be described below. For ease of explanation, the same reference numerals will be used to designate components having the same functions as those described in the above embodiment, and the description thereof will not be repeated.

[0115] In the first embodiment, a configuration in which the display mode of the numeric buttons 301 is changed has been described, but this is not limiting. In the second embodiment, a configuration in which a button corresponding to one of the floors of the building, different from the numeric buttons 301, is displayed on the screen, and the display mode changes depending on whether the floor corresponding to the button is a restricted floor or not, will be described.

[0116] Fig. 13 is a block diagram showing the configuration of an elevator system 100A according to embodiment 2. As shown in Fig. 13, elevator system 100A according to embodiment 2 includes a display system 200A instead of display system 200. Display system 200A includes a destination floor registration device 1A instead of destination floor registration device 1. Destination floor registration device 1A includes a control unit 11A and a storage unit 14A instead of control unit 11 and storage unit 14.

[0117] In addition to the authentication result information 141 and the destination floor information 142, the storage unit 14A stores floor information 143A, which stores, for each specific floor, specific floors (specific floors) in the building and information indicating whether the specific floor is a restricted floor or a registerable floor. A specific floor is a floor represented by something other than a number, and may be, for example, a floor where a lobby, garage, rooftop, or heliport is located. A specific floor may also include an evacuation floor. A specific floor is not limited to the above. For example, a building may have multiple lobby floors.

[0118] Control unit 11A differs from control unit 11 in that it includes display control unit 113A instead of display control unit 113. Display control unit 113A causes display unit 13 to display numeric keypad 302A including specific floor buttons associated with specific floors at each stage at which operation reception unit 111 can receive input operations.

[0119] FIG. 14 is a diagram showing an example of a screen including specific floor buttons. As shown in FIG. 14, the specific floor buttons include a button (reference numeral 1401) associated with the floor where the lobby is located, a button (reference numeral 1402) associated with the floor where the garage is located, a button (reference numeral 1403) associated with the floor where the roof is located, a button (reference numeral 1404) associated with the floor where the heliport is located, and an evacuation floor button 304. As shown by reference numerals 1401 to 1404, each of the specific floor buttons is associated with a symbol or letter indicating the specific floor corresponding to the specific floor button. The evacuation floor button 304 may also be included in the specific floor buttons. Furthermore, if only one basement floor can be specified as a destination floor, the basement floor button 303 may also be included in the specific floor buttons. Note that the specific floor buttons shown in FIG. 14 are merely examples, and other specific floor buttons may be displayed, or some of the specific floor buttons shown in FIG. 14 may be displayed. For example, if a building has multiple lobby floors, specific floor buttons with symbols indicating the respective lobby floors may be displayed individually on the display unit 13.

[0120] 14 shows an example of a screen in which the numeric keypad 302A includes the number buttons 301 and the specific floor buttons, but the screen displayed by the display control unit 113A is not limited to this. For example, the display control unit 113A may display on the display unit 13 a numeric keypad 302A that does not include the number buttons 301 and only includes the specific floor buttons.

[0121] Each of the floors associated with the specific floor buttons is set as a restricted floor or a registerable floor. The display control unit 113A refers to the floor information 143A and displays the specific floor buttons in the first display mode or the second display mode. An example will be described in which the floors where the garage is located and the floors where the heliport is located are restricted floors. In this case, the display control unit 113A displays the specific floor buttons (reference numerals 1402 and 1404) associated with the restricted floors in the first display mode (reference numeral Q). Furthermore, the display control unit 113A displays the specific floor buttons (reference numerals 303, 304, 1401, and 1403) associated with the registerable floors in the second display mode (reference numeral P).

[0122] When the operation reception unit 111 receives an input operation on a specific floor button, the registration unit 114 identifies the floor corresponding to the specific floor button for which the input operation was performed. If the identified floor is a registerable floor, or if the identified floor is a restricted floor and the user is authenticated, the registration unit 114 permits registration of the destination floor. If the identified floor is a restricted floor and the user is not authenticated, the registration unit 114 rejects registration of the destination floor.

[0123] As described above, the display system 200A displays a screen including specific floor buttons associated with each specific floor, and each specific floor button is displayed in a different display mode depending on whether the corresponding specific floor is a restricted floor or not. This allows the user to know which of the specific floors is a restricted floor before performing an input operation.

[0124] [Embodiment 3] In the first embodiment, a configuration has been described in which the authentication device 5 transmits information indicating the authentication result of the user to the destination floor registration device 1, but this is not limiting. In the third embodiment, a configuration will be described in which the destination floor registration device 1 acquires information indicating the authentication result from the group management control device 2B.

[0125] Fig. 15 is a block diagram showing the configuration of an elevator system 100B according to embodiment 3. As shown in Fig. 15, the elevator system 100B according to embodiment 3 includes a group management control device 2B and an authentication device 5B instead of the group management control device 2 and the authentication device 5. The authentication device 5B is also called a security server.

[0126] The authentication device 5B includes a control unit 51B and a storage unit 52B. The storage unit 52B stores a device DB (database) 522 in addition to the registration information 521. The device DB 522 is a database in which, for each identification information of the reading device 6, information associating the identification information of the reading device 6 with the identification information of the destination floor registration device 1 corresponding to the reading device 6 is stored.

[0127] The control unit 51B of the authentication device 5B authenticates the user when it acquires the user information read by the reading device 6. Furthermore, the control unit 51B refers to the device DB 522 and identifies the identification information of the destination floor registration device 1 that corresponds to the identification information of the reading device 6 that is the sender of the user information. The control unit 51B transmits the identified identification information of the destination floor registration device 1 together with information indicating the authentication result of the user to the group management control device 2B.

[0128] The group management control device 2B receives information indicating the authentication result of the user and the identification information of the destination floor registration device 1. The group management control device 2B transmits the information indicating the authentication result of the user to the destination floor registration device 1 identified by the received identification information. This allows the update unit 112 of the destination floor registration device 1 to receive the authentication result information 141.

[0129] In the above example, a configuration has been described in which the authentication device 5B and the group management control device 2B are separate devices, but this is not limiting. For example, the group management control device 2B may have the configuration of the authentication device 5B. In this case, the reading device 6 transmits user information to the group management control device 2B. Furthermore, the group management control device 2B authenticates the user and identifies the destination floor registration device 1 corresponding to the reading device 6, and transmits information indicating the authentication result to the identified destination floor registration device 1.

[0130] [Modification] <Variation 1> In the above-described embodiments, the building has two floors, but this is not limiting. For example, the building may have three floors. Furthermore, at least one of the three floors may be set as a restricted floor. In this case, the stages that can accept operations on the numeric buttons 301 include the fourth stage.

[0131] The fourth stage is a stage after the second stage, and is a stage at which a third operation on the numeric buttons 301 can be accepted. In a series of call registrations, the fourth stage corresponds to the period from when the first numeric input operation and the second numeric input operation are performed until a predetermined time has elapsed or until the operation accepting unit 111 accepts a third operation on the numeric buttons 301.

[0132] When the restricted floor is a three-digit floor, the display control unit 113, at the stage when the operation receiving unit 111 can receive the third input operation on the number button 301, makes the display mode of the number button 301 corresponding to the number corresponding to the ones digit of the restricted floor different from the display mode of the number buttons 301 other than the number button 301.

[0133] Specifically, in the fourth stage, the display control unit 113 causes the display unit 13 to display a fourth screen. Fig. 16 is a diagram showing an example of the fourth screen. As shown in Fig. 16, the fourth screen includes input information (reference symbol 1601) input in a stage prior to the fourth stage, numeric buttons 301, a basement floor button 303, and an evacuation floor button 304. As shown in Fig. 16, on the fourth screen, the display control unit 113 causes the numeric button 301 associated with the number corresponding to the ones digit of the restricted floor among the three-digit floors to be displayed in the first display mode (reference symbol Q), and causes the numeric buttons 301 other than the numeric button 301 to be displayed in the second display mode (reference symbol P).

[0134] According to the above configuration, the user can know which of the three-digit floors is a restricted floor after performing the second input operation on the number button 301 (second number input operation) and before performing the third input operation on the number button 301 (third number input operation).

[0135] <Variation 2> In the above-described embodiments, the building has two floors, but this is not limiting. For example, the building may have two basement floors. Furthermore, at least one of the two basement floors may be set as a restricted floor. In this case, the stages that can accept operations on the numeric buttons 301 include the fifth stage.

[0136] The fifth stage is a stage after the second or third stage, and is a stage at which a second operation on the numeric buttons 301 can be accepted. In a series of call registrations, the fifth stage corresponds to the period from when the basement floor input operation and the first numeric input operation are performed until a predetermined time has elapsed or until the operation acceptance unit 111 accepts a second operation on the numeric buttons 301. The operation on the numeric buttons 301 that the operation acceptance unit 111 can accept in the fifth stage is the second operation on the numeric buttons 301 in a series of call registrations, and therefore corresponds to the "second numeric input operation."

[0137] In the fifth stage, the operation receiving unit 111 waits for the reception of the second number input operation. Also, in the fifth stage, the display control unit 113 displays the fifth screen. FIG. 17 is a diagram showing an example of the fifth screen. As shown in FIG. 17, the fifth screen includes input information (reference numeral 1701) input in a stage prior to the fifth stage, the number buttons 301, the basement floor button 303, and the evacuation floor button 304.

[0138] On the fifth screen, the display control unit 113 displays the number buttons 301 associated with the number corresponding to the ones digit of the restricted floor among the two-digit basement floors in the first display mode (symbol Q), and displays the number buttons 301 other than the number buttons 301 in the second display mode (symbol P). This allows the user to know which floor among the two-digit basement floors is the restricted floor after performing the first number input operation and the basement floor input operation but before performing the second number input operation.

[0139] <Variation 3> In the above-described embodiments, the display system 200 is described as including the destination floor registration device 1, but the present invention is not limited to this. For example, the elevator system 100 may be provided with a first device including the operation reception unit 111, the display control unit 113, the input unit 12, and the display unit 13, and a second device including other components of the destination floor registration device 1, which are separate devices, or the display system 200 may be provided with only the first device.

[0140] In this case, operation receiving unit 111 transmits information indicating the content of the received operation to the second device. Based on various information, the second device transmits information indicating the content to be displayed on display unit 13 to the first device as appropriate. Display control unit 113 displays a screen based on the received information on display unit 13. According to the above configuration, the processing performed in display system 200 can be simplified.

[0141] <Variation 4> In the above-described first embodiment, the display control unit 113 has been described as displaying the numeric buttons 301 corresponding to the numbers included in the restricted floors in the second display mode, but this is not limiting. Fig. 18 is a diagram showing yet another example of the second screen. Fig. 18 illustrates the second screen that is displayed after 3 is input in the first numeric input operation when the third basement floor of a building is a restricted floor. The second screen shown in Fig. 18 includes the input information (reference numeral 1801) input in the first stage, the numeric buttons 301, the basement floor button 303, and the evacuation floor button 304.

[0142] 18, after the operation receiving unit 111 receives an operation to input a number, if the basement floor including the input number is a restricted floor, the display control unit 113 may display the basement floor button 303 in the second display mode (symbol P). This allows the user to understand that the basement floor including the input number is a restricted floor after performing the operation to input a number.

[0143] If the building has two-digit basement floors, the display control unit 113 may perform similar control on the fifth screen. For example, if the thirteenth basement floor is a restricted floor and 1 is input in the first number input operation and 3 is input in the second number input operation, the display control unit 113 may display the basement floor button 303 in the second display mode (symbol P) on the fifth screen.

[0144] [Software implementation example] The functions of elevator systems 100, 100A-100B and display systems 200, 200A (hereinafter referred to as "systems") can be realized by a program that causes a computer to function as the system, and a program that causes a computer to function as each control block of the system (particularly each part included in control units 11, 11A).

[0145] In this case, the system includes a computer having at least one control device (e.g., a processor) and at least one storage device (e.g., a memory) as hardware for executing the program. The control device and storage device execute the program, thereby realizing the functions described in each of the above embodiments.

[0146] The program may be non-transitory and may be recorded on one or more computer-readable recording media. The recording media may or may not be included in the system. In the latter case, the program may be supplied to the device via any wired or wireless transmission medium.

[0147] Furthermore, some or all of the functions of the control blocks can be realized by logic circuits. For example, an integrated circuit in which a logic circuit that functions as each of the control blocks is formed is also included in the scope of the present invention. In addition, the functions of the control blocks can also be realized by, for example, a quantum computer.

[0148] Furthermore, each process described in each of the above embodiments may be executed by AI (Artificial Intelligence). In this case, the AI ​​may run on the control device or on another device (for example, an edge computer or a cloud server).

[0149] The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the claims. Embodiments obtained by appropriately combining the technical means disclosed in different embodiments are also included in the technical scope of the present invention.
