Description

The present invention relates to an elevator display control device, an elevator, and an elevator display control method.

Generally, passengers near the control panel inside the car will, as a consideration, press the open button to considerate people who are about to board the car, or to considerate people who are about to disembark.

In recent years, an increasing number of elevators have adopted contactless destination floor registration devices to prevent virus infection through touching buttons, but conventional contact-type buttons are generally used for the open and close buttons. This is to prevent situations in which the car doors do not open or close properly because the sensor does not detect the button even though it has actually been pressed. Therefore, even when a contactless destination floor registration device is used, passengers cannot avoid touching the open or close button when pressing it.

If the display device inside the car shows information about people who are planning to board or disembark in the future, it is thought that this will prevent the open button from being pressed unnecessarily when these people are not present.

Patent Document 1 discloses an elevator display device that is provided at an elevator hall and includes a display unit that displays the occupancy level of the car, a sensor for detecting a parameter related to the occupancy level, and a control unit that controls the display state of the display unit according to the occupancy level that is determined based on the detection results of the sensor.

JP 2021-181374 A

However, Patent Document 1 does not disclose how to display information about people who are planning to board or disembark in the elevator on a display device. Patent Document 1 also does not disclose a method for preventing contact infection with the virus.

The present invention has been made in consideration of the above-mentioned situation, and its object is to reduce the frequency of incidents in which the open button inside the elevator car is unnecessarily pressed, thereby reducing the possibility of passengers becoming infected with the virus through contact.

In order to solve the above problems and achieve the object of the present invention, the elevator display control device according to the present invention is an elevator display control device that controls the display content on a display unit provided in a car having a contact-type opening button, and includes a call registration information acquisition unit that acquires registration information of a call assigned to the car, and a display control unit that generates at least one of information on the number of passengers scheduled to board the car and the number of passengers scheduled to disembark from the car based on the registration information of the call acquired by the call registration information acquisition unit and displays the information on the display unit. The call registration information acquisition unit acquires call registration information from a destination floor registration device, and the display control unit displays the number of passengers scheduled to board and/or the number of passengers scheduled to disembark at each floor of a building in which the elevator is installed on the display unit, and when a call is registered from the destination floor registration device, adds the number of passengers scheduled to board the car at the landing floor where the call is registered to the number of passengers scheduled to board displayed on the display unit, and then adds the displayed number of passengers scheduled to disembark from the car at the destination floor after the car departs from the floor.

According to the present invention, the frequency of occurrence of situations in which the open button inside the elevator is pressed unnecessarily can be reduced, thereby reducing the possibility of users becoming infected with the virus through contact.

The present invention is not limited to the embodiments, and the various numerical values in the embodiments are merely examples. Furthermore, in this specification and drawings, identical components or components having substantially the same functions will be given the same reference numerals, and duplicate explanations will be omitted.

<Elevator system configuration>
First, the configuration of an elevator system according to an embodiment of the present invention will be described with reference to Fig. 1. Fig. 1 is a schematic configuration diagram of an elevator system 100.

As shown in FIG. 1, the elevator system 100 (an example of an elevator) includes an elevator control device 1, a car 4, hall buttons 10_1 to 10_5 (hall buttons 10_2 to 10_4 are not shown), and hall lanterns 11_1 to 11_15 (hall lanterns 11_4 to 11_12 are not shown).

The configuration of the car 4 will be described using car 4_1 of the first car as an example. The configurations of car 4_2 of the second car and car 4_3 of the third car are the same as car 4_1, so the description of these will be omitted here.

Note that Figure 1 shows an example in which three elevators, No. 1 to No. 3, are provided inside the elevator, but the present invention is not limited to this. The number of elevators may be two or less, or four or more. Hereinafter, when there is no need to individually identify the elevator cars 4_1 to 4_3, they will be collectively referred to as elevator car 4.

The car 4_1 ascends and descends in a hoistway (not shown) formed in a building, carrying people and baggage. A main rope with a counterweight at its end is connected to the top surface of the car 4_1, and the main rope is wound around a hoist (these components are not shown in FIG. 1). The operation of the hoist is controlled by the unit control device 3_1, causing the car 4_1 to ascend and descend in the hoistway.

The elevator 4_1 also includes an in-cab destination floor registration device 5_1 and an in-cab card reader 6_1.

The in-car destination floor registration device 5_1 includes a display unit 51_1 and a destination floor button 52_1. The configurations of the in-car destination floor registration device 5_2 and the in-car destination floor registration device 5_3 are the same as those of the in-car destination floor registration device 5_1, so their explanations are omitted here. In the following explanation, when it is not necessary to individually identify the in-car destination floor registration devices 5_1 to 5_3, they are collectively referred to as the in-car destination floor registration device 5.

The display unit 51_1 is composed of a panel made of, for example, an LCD (Liquid Crystal Display) or an organic EL (Electronic Luminescent) panel. The display unit 51_1 displays information such as the number of people planning to board and disembark for the car 4_1 based on the control of the elevator display control device 20 in the group management control device 2. The display unit 51_1 may also display other information such as disaster information in the event of a disaster or news.

Destination floor button 52_1 includes buttons indicating destination floors. Destination floor button 52_1 is configured as a non-contact button that operates when an infrared sensor (not shown) detects the proximity of a user's hand, finger, etc. Destination floor button 52_1 identifies the destination floor based on the detected position of the hand, finger, etc., and outputs information on the identified destination floor to group management control device 2. In the following description, when it is not necessary to individually identify display units 51_1 to 51_3, these are collectively referred to as display unit 51. Also, when it is not necessary to individually identify destination floor buttons 52_1 to 52_3, these are collectively referred to as destination floor button 52.

In this embodiment, an example is given in which the destination floor button 52 is configured as a non-contact button, but the present invention is not limited to this. The destination floor button 52 may be configured as a contact button.

Contact-type open and close buttons (not shown) and an in-car card reader 6_1 are provided below the destination floor button 52_1. The in-car card reader 6_1 reads the destination floor information registered on a card held up by the user, and outputs the read destination floor information to the group management control device 2. The in-car card readers 6_2 and 6_3 have the same configuration as the in-car card reader 6_1, so their explanation will be omitted here. In the following explanation, when there is no need to individually identify the in-car card readers 6_1 to 6_3, they will be collectively referred to as the in-car card reader 6.

A platform button 10_1 is provided at platform P_1 on the 1st floor, and a platform button 10_5 is provided at platform P_5 on the 5th floor.

For example, when a user presses platform button 10_5, call information is transmitted from platform button 10_5 to the group management control device 2 to summon car 4 to 5F, which is the floor where platform button 10_5 is located.

In the following description, when there is no need to individually identify the boarding points P_1 to P_5 (boarding points P_2 to P4 are not shown), they will be collectively referred to as boarding point P. Also, when there is no need to individually identify the boarding point buttons 10_1 to 10_5, they will be collectively referred to as boarding point buttons 10.

Hall lanterns 11_1 to 11_3 are provided at platform P_1 on the 1st floor, and hall lanterns 11_13 to 11_15 are provided at platform P_5 on the 5th floor.
Hall lanterns 11_1 and 11_13 are provided corresponding to car No. 1, and by lighting a lamp (not shown) based on the control of the car control device 3_1, notify users at any of the boarding areas P1 to P5 that the car 4_1 is approaching that floor.

Hall lanterns 11_2 and 11_14 are provided corresponding to unit 2, and by lighting a lamp (not shown) based on the control of unit control device 3_2, notify users at any of boarding areas P1 to P5 that car 4_2 is approaching that floor.

Furthermore, hall lanterns 11_3 and 11_15 are provided corresponding to unit No. 3, and by lighting a lamp (not shown) based on the control of unit control device 3_3, notify users at any of boarding areas P1 to P5 that car 4_3 is approaching that floor.

In the following description, when there is no need to individually identify hall lanterns 11_1 to 11_15 (hall lanterns 11_4 to 11_12 are omitted in FIG. 1), they will be collectively referred to as hall lantern 11. In addition, the number of floors of a building on which an elevator is provided is not limited to the five floors shown in FIG. 1.

The car control devices 3_1 to 3_3 will be described using the car control device 3_1 as an example. The car control device 3_1 is provided, for example, in a machine room (not shown) above the car 4_1. Based on a lift/lower or stop command from the group management control device 2, the car control device 3_1 controls the lifting and lowering operation of the car 4_1, the opening and closing operation of a door (not shown), and the display operation of the in-car destination floor registration device 5_1 inside the car 4_1. The car control device 3_1 also transmits information such as pressing information on the destination floor button 52_1 of the in-car destination floor registration device 5_1 to the group management control device 2.

Furthermore, the unit control device 3_1 controls the turning on and off of hall lanterns 11_1, 11_4, 11_7, 11_10 and 11_13 (only hall lanterns 11_1 and 11_13 are shown in Figure 1).

The configurations of the unit control device 3_2 and the unit control device 3_3 are the same as that of the unit control device 3_1, so their explanation will be omitted here. In the following explanation, when there is no need to individually identify the unit control devices 3_1 to 3_3, they will be collectively referred to as the unit control device 3.

The group management control device 2 registers a call to the corresponding elevator based on the call information (information on the elevator floor, destination floor, etc.) transmitted from the elevator button 10, the in-car destination floor registration device 5, the in-car card reader 6, the elevator destination floor registration devices 12_1 and 12_2 shown in Figure 2, and the destination floor registration device 141 installed on the flapper gate 14, and outputs instructions to raise/lower or stop the elevator based on the call registration to the elevator control device 3 which controls the operation of the corresponding elevator.

The group management control device 2 also includes an elevator display control device 20. The elevator display control device 20 generates information on the number of passengers planning to board and disembark in each car based on the call registration information acquired by the group management control device 2, and displays this information on the display unit 51 in each car 4. The configuration of the control system of the elevator display control device 20 will be described in detail with reference to Figure 3 described below.

<Platform destination floor registration device and flapper gate>
Next, an example of installation and configuration of the landing destination floor registration device 12 and the flapper gate 14 at the landing P will be described with reference to Fig. 2. Fig. 2 is a diagram showing an example of installation of the landing destination floor registration device 12 and the flapper gate 14 at the landing P.

In the example shown in Figure 2, a landing destination floor registration device 12_1 is installed between machine No. 1 having car 4_1 and machine No. 2 having car 4_2, and a landing destination floor registration device 12_2 is installed between machine No. 2 and machine No. 3 having car 4_3.

In addition, above each of the landing doors of platforms 1 to 3, landing platform user detection sensors 13_1 to 13_3 corresponding to each platform are provided. The landing platform user detection sensors 13_1 to 13_3 are composed of, for example, image sensors, and obtain information on the number of users waiting at landing P.

Furthermore, flapper gates 14_1 to 14_3 are installed at the entrance to platform P. The flapper gates 14_1 to 14_3 are gates that manage the entry and exit of users to the building (platform P).

[Platform destination floor registration device]
The hall destination floor registration devices 12_1 and 12_2 are devices for allowing users at the hall P to register information about their destination floors.

The platform destination floor registration devices 12_1 and 12_2 will be described using the platform destination floor registration device 12_1 as an example. The configuration of the platform destination floor registration device 12_2 is the same as that of the platform destination floor registration device 12_1, so the description thereof will be omitted here.

The platform destination floor registration device 12_1 is composed of a card reader (not shown) or a Near Field Communication (NFC) reader, and reads information stored in an IC tag or IC card (not shown) held up by a user. The IC tag or IC card stores information such as the user ID and the destination floor.

The platform destination floor registration device 12_1 transmits information on the destination floor registered by the user, information on the floor (platform floor) on which the platform destination floor registration device 12_1 is installed, and information on the user ID to the group management control device 2 (see FIG. 1). In the following description, when there is no need to individually identify the platform destination floor registration devices 12_1 and 12_2, they are collectively referred to as the platform destination floor registration device 12.

[Flapper Gate]
The flapper gates 14_1 to 14_3 will be described by taking the flapper gate 14_1 as an example. The configurations of the flapper gates 14_2 and 14_3 are the same as that of the flapper gate 14_1, so descriptions thereof will be omitted here.

The flapper gate 14_1 is a gate that manages users' entry and exit to the building, and is equipped with a destination floor registration device 141_1 composed of a card reader or NFC reader (not shown), and a gate 142_1.

The destination floor registration device 141_1 reads information stored in an IC tag or IC card held up by a user. If the user holding the IC tag or IC card is a person present in the building, the IC tag or IC card also registers the user's destination floor information in addition to the user ID. The destination floor registration device 141_1 transmits the read user ID, destination floor information, and landing floor information to the group management control device 2. Gate 142_1 opens and closes based on the control of the group management control device 2.

In the following description, when there is no need to identify the flapper gates 14_1 to 14_3 individually, they are collectively referred to as flapper gates 14. Furthermore, when there is no need to identify the destination floor registration devices 141_1 to 141_3 individually, they are collectively referred to as destination floor registration device 141. Furthermore, when there is no need to identify the gates 142_1 to 142_2 individually, they are collectively referred to as gate 142.

In addition, the installation locations and numbers of the platform destination floor registration device 12, platform user detection sensor 13, and flapper gate 14 at platform P are merely examples and are not limited to the example shown in Figure 2.

<Configuration of the control system of the elevator display control device>
Next, the configuration of a control system of the elevator display control device 20 according to this embodiment will be described with reference to Fig. 3. Fig. 3 is a block diagram showing an example of the configuration of the control system of the elevator display control device 20.

As shown in Figure 3, the elevator display control device 20 includes a call registration information acquisition unit 21, an operation information acquisition unit 22, and a display control unit 23. The call registration information acquisition unit 21 acquires call registration information from the group management control device 2.

The operation information acquisition unit 22 acquires operation information for each of the elevators, No. 1 to No. 3. The operation information includes, for example, information on the floors at which each elevator stops, information on the direction of ascent and descent, and information on its position in the elevator shaft.

The display control unit 23 calculates the number of people who plan to board (the number of people planned to board) and the number of people who plan to disembark (the number of people planned to disembark) on each car at each floor, based on the call registration information acquired by the call registration information acquisition unit 21 and the operation information acquired by the operation information acquisition unit 22. Then, the information on the number of people planned to board and disembark on each floor is displayed on the display unit 51 (see Figure 1) in the car 4 of each car. The information on the number of people planned to board and disembark on each floor on the display unit 51 can be displayed, for example, before or when the doors are opened, but may also be displayed all the time.

<Example of computer hardware configuration>
Next, the hardware configuration of each device for realizing the functions of the control system of the elevator system 100 shown in Fig. 1 will be described with reference to Fig. 4. Fig. 4 is a block diagram showing an example of the hardware configuration of each device provided in the elevator system 100.

The computer 200 is hardware used as a so-called computer. The computer 200 includes a CPU (Central Processing Unit) 201, a ROM 202, and a RAM (Random Access Memory) 203, each of which is connected to a bus B. The computer 200 further includes a non-volatile storage 204 and a network interface 205.

The CPU 201 reads out from the ROM 202 the program code of the software that realizes each function according to this embodiment and executes it. Note that the computer 200 may include a processing device such as an MPU (Micro-Processing Unit) instead of the CPU 201. Variables, parameters, etc. that are generated during the calculation process are temporarily written to the RAM 203.

As the non-volatile storage 204, for example, a hard disk drive (HDD), a solid state drive (SSD), a flexible disk, an optical disk, a magneto-optical disk, a CD-ROM, a CD-R, a non-volatile memory card, etc., can be used. In addition to an operating system (OS) and various parameters, this non-volatile storage 204 records a program for causing the computer 200 to function. The program may be stored in the ROM 202. In other words, the non-volatile storage 204 or the ROM 202 is used as an example of a computer-readable non-transient recording medium that stores a program executed by the computer.

The network interface 205 may be, for example, a NIC (Network Interface Card), and can transmit and receive various types of data between external devices via a network such as a LAN or a communication line.

<Example of the configuration inside the car and example of display on the display unit>
Next, a description will be given of an example of the internal configuration of the car 4 and an example of displaying the number of people scheduled to get on and the number of people scheduled to get off on the display unit 51 with reference to Fig. 5. Fig. 5 is a diagram showing an example of the internal configuration of the car 4 and an example of displaying on the display unit 51.

Figure 5A is a diagram showing an example of the internal configuration of the elevator car 4. As shown in Figure 5A, inside the elevator car 4, a door 7, an in-car destination floor registration device 5, an open button 8, a close button 9, and an in-car card reader 6 are provided.

The open button 8 and the close button 9 are contact-type buttons. In other words, if a user of the car 4 wants to keep the door 7 of the car 4 open, the user needs to touch the open button 8 with his/her finger, and if the user wants to close the door 7, the user needs to touch the close button 9 with his/her finger.

Figure 5B is a diagram showing an example of the display of the number of people planning to board and the number of people planning to disembark on the display unit 51 of the in-car destination floor registration device 5. In Figure 5B, the number of people planning to board and the number of people planning to disembark are displayed in the display format of "X people/Y people" ("X" and "Y" are each an integer of 1 or greater) at positions on the display unit 51 of the in-car destination floor registration device 5 that correspond to each floor of the destination floor buttons 52.

Specifically, it is shown that the number of people planning to board on the 1st floor is "3 people", and the number of people planning to disembark is "0 people". It is also shown that the number of people planning to board and the number of people planning to disembark on the 2nd floor are both "0 people". It is shown that the number of people planning to board on the 3rd floor is "1 person", and the number of people planning to disembark is "0 people". It is shown that the number of people planning to board on the 4th floor is "3 people", and the number of people planning to disembark is "0 people". It is also shown that the number of people planning to disembark on the 5th floor is "0 people", and the number of people planning to disembark is "5 people".

Therefore, the user of car 4 only needs to press open button 8 until three users have boarded on the first floor, until one user has boarded on the third floor, and until five users have disembarked on the fifth floor.

In other words, by looking at the display on the display unit 51, passengers in the elevator car 4 can understand that there is no need to press the open button 8 on floors where passengers do not plan to board or disembark, such as the second floor. This reduces the chances of unnecessary contact by passengers with the open button 8, thereby reducing the possibility of passengers contracting the virus through contact.

In the example shown in FIG. 5, both the number of people planning to board car 4 and the number of people planning to disembark from car 4 are displayed on display unit 51, but the present invention is not limited to this. Display unit 51 may display only one of the information on the number of people planning to board and the number of people planning to disembark.

<Elevator display control method by elevator display control device>
Next, an elevator display control method by the elevator display control device 20 according to this embodiment will be described with reference to Figs. 6 to 8.

[Elevator display control process based on call information from destination floor registration device]
Fig. 6 is a flowchart showing an example of the procedure of elevator display control processing based on call information from the in-car destination floor registration device 5 (see Fig. 1), the destination floor registration device 141 of the flapper gate 14 (see Fig. 2), or the landing destination floor registration device 12 (see Fig. 2). Fig. 6A is a flowchart showing an example of the procedure of the display number of people addition processing of the number of people planning to get on and the number of people planning to get off, and Fig. 6B is a flowchart showing an example of the procedure of the display number of people subtraction processing of the number of people planning to get on and the number of people planning to get off.

In the process shown in Figure 6A, first, the call registration information acquisition unit 21 (see Figure 3) of the elevator display control device 20 determines whether or not the destination floor has been registered in the various destination floor registration devices described above (step S1). If it is determined in step S1 that the destination floor has not been registered (if step S1 is determined as NO), the call registration information acquisition unit 21 repeats the determination in step S1.

On the other hand, if it is determined in step S1 that a destination floor has been registered in the destination floor registration device (if step S1 is determined to be YES), the display control unit 23 (see Figure 3) adds the displayed number of passengers planning to board corresponding to the boarding floor where the destination floor is registered to the original number (the number of passengers planning to board and/or the number of passengers planning to disembark displayed on the display unit 51) by the number of passengers registered (step S2).

Next, the display control unit 23 judges whether or not the elevator (car 4) has departed from the floor where it was stopped, based on the elevator operation information acquired by the operation information acquisition unit 22 (step S3). If it is judged in step S3 that car 4 has not departed (if the judgment in step S3 is NO), the display control unit 23 repeats the judgment in step S3.

On the other hand, if it is determined in step S3 that the elevator has departed (if step S3 is determined to be YES), the display control unit 23 increments the display number of people expected to disembark that is associated with each registered destination floor by the number of people registered (step S4). After processing in step S4, the elevator display control process by the elevator display control device 20 ends.

In the process shown in Fig. 6B, first, the display control unit 23 of the elevator display control device 20 determines whether or not the elevator has departed from the floor where it was stopped, based on the elevator operation information acquired by the operation information acquisition unit 22 (step S11). If it is determined in step S11 that the elevator has not departed (if the determination in step S11 is NO), the display control unit 23 repeats the determination in step S11.

On the other hand, if it is determined in step S11 that the elevator has departed (if step S11 is determined as YES), the display control unit 23 subtracts the displayed numbers of people planning to board and disembark that were associated with the destination floor from the original numbers (step S12). After the processing of step S12, the elevator display control processing by the elevator display control device 20 ends.

[Elevator display control processing based on call information from card reader inside the car]
FIG. 7 is a flowchart showing an example of the procedure of elevator display control processing based on call information from the in-car card reader 6 (see FIG. 1).

First, the call registration information acquisition unit 21 of the elevator display control device 20 determines whether or not a destination floor has been registered in the in-car card reader 6 (step S21). If it is determined in step S21 that a destination floor has not been registered (if step S21 returns NO), the call registration information acquisition unit 21 repeats the determination in step S21.

On the other hand, if it is determined in step S21 that a destination floor has been registered in the car card reader 6 (if step S21 is determined to be YES), the display control unit 23 adds the displayed number of people expected to disembark corresponding to each registered destination floor by the number of people registered (step S22).

Next, the display control unit 23 determines whether the elevator has departed from the floor where it was stopped, based on the elevator operation information acquired by the operation information acquisition unit 22 (step S23). If it is determined in step S23 that the elevator has not departed (if step S23 is judged as NO), the display control unit 23 repeats the judgment in step S23.

On the other hand, if it is determined in step S23 that the elevator has departed (if step S23 is determined to be YES), the display control unit 23 subtracts the displayed number of people scheduled to disembark that was associated with the departure floor (step S24). After processing in step S24, the elevator display control process by the elevator display control device 20 ends.

[Elevator display control process based on detection results by hall user detection sensor and call information from hall button]
Fig. 8 is a flowchart showing an example of the procedure of elevator display control processing based on the detection result by the hall user detection sensor 13 (see Fig. 2) and the call information from the hall button 10 (see Fig. 1). Fig. 8A is a flowchart showing an example of the procedure of the display number of people planning to board, and Fig. 8B is a flowchart showing an example of the procedure of the display number of people planning to board.

In the process shown in Figure 8A, first, the call registration information acquisition unit 21 of the elevator display control device 20 determines whether any of the hall buttons 10 have been pressed (step S31). If it is determined in step S31 that none of the hall buttons 10 have been pressed (if step S31 is determined as NO), the call registration information acquisition unit 21 repeats the determination in step S31.

On the other hand, if it is determined in step S31 that any of the hall buttons 10 has been pressed (if step S31 is determined as YES), the display control unit 23 adds the displayed number of people expected to board by the number of people detected by the hall user detection sensor 13 at the floor where the pressed hall button 10 is installed (step S32). After processing in step S32, the elevator display control processing by the elevator display control device 20 ends.

In the process shown in Fig. 8B, first, the display control unit 23 judges whether or not the elevator has departed from the floor where it was stopped, based on the elevator operation information acquired by the operation information acquisition unit 22 (step S41). If it is judged in step S41 that the elevator has not departed (if the judgment in step S41 is NO), the display control unit 23 repeats the judgment in step S41.

On the other hand, if it is determined in step S41 that the elevator has departed (if step S41 is determined to be YES), the display control unit 23 subtracts the displayed number of passengers associated with the departure floor (step S42). After processing in step S42, the elevator display control process by the elevator display control device 20 ends.

In the above-described embodiment, the elevator display control device 20 includes a call registration information acquisition unit 21 that acquires registration information of a call assigned to the car 4, and a display control unit 23 that generates at least one piece of information regarding the number of people planning to board the car 4 and the number of people planning to disembark from the car 4 based on the registration information of the call acquired by the call registration information acquisition unit 201, and displays the information on the display unit 51.

Therefore, according to this embodiment, the passengers in the elevator 4 can check the information on how many passengers are boarding or disembarking at which floor by checking the display content on the display unit 51 in the elevator 4. In other words, the passengers in the elevator 4 do not need to press the open button 8 at floors where passengers are not scheduled to board and/or disembark. Also, even at floors where passengers are scheduled to board and/or disembark, after it is confirmed that the number of passengers who are scheduled to board and/or disembark, as displayed on the display unit 51, have boarded, or the number of passengers who are scheduled to disembark, has disembarked, there is no need to press the open button 8. Therefore, according to this embodiment, the opportunity for unnecessary contact by the passengers with the open button 8 can be reduced, thereby reducing the possibility of the passengers being infected with the virus through contact.

In the above-described embodiment, the display control unit 23 of the elevator display control device 20 causes the display unit 51 of the car 4 to display the number of people planning to board and/or disembark at each floor of the building in which the elevator is installed. Therefore, according to this embodiment, passengers in the car 4 can visually and easily grasp information regarding how many passengers will board or disembark at each floor.

Furthermore, in the above-described embodiment, the display control unit 23 causes the display unit 51 to display the number of people planning to board and/or disembark at the timing before or when the door 7 (see FIG. 5) of the car 4 opens, determined based on the operation information acquired by the operation information acquisition unit 22. Therefore, according to this embodiment, a user in the car 4 can appropriately determine whether or not it is necessary to press the open button 8 at the timing when the car 4 stops to disembark.

Furthermore, in the above-described embodiment, the in-car destination floor registration device 5 is provided in the car 4 and is equipped with a non-contact type destination floor button 52. Therefore, according to this embodiment, even though a non-contact operation can be performed when specifying a destination floor, even if the opening button is configured as a conventional contact type button, the opportunity for touching the opening button 8 can be reduced, thereby reducing the opportunity for users to become infected with a virus through contact.
