The face authentication camera 35 is arranged above the display unit 34, captures an image of a subject in a predetermined field angle area in front of the camera at a predetermined frame rate and a predetermined resolution, and generates image data of the captured image (captured image). and outputs the generated image data to the control unit 31 . The face authentication camera 35 is an example of an imaging unit. The predetermined angle of view area is set to an angle of view that allows the user's face to be captured when the user who is going to register the destination floor is in front of the destination floor registration device 30 . The predetermined resolution may be any resolution at which face detection and face matching can be performed appropriately during face authentication, and may be HD, FHD, 4K, or the like, for example. The frame rate may be any rate, such as 15 fps or 30 fps.

FIG. 5 is a diagram showing the configuration of the user DB stored in the storage unit 12 of the group supervisory control device 10. As shown in FIG.

The user DB records the first default destination floor and the second default destination floor in association with the face data of the user. Registration of such information in the user DB is performed by, for example, a building manager.

“Face data” is data used in face authentication of the user. The “face data” may be face image data (face image data) or face feature point data (face feature point data), as long as the face of the user can be distinguished. However, the case where the "face data" is face feature point data will be described below. Facial feature point data is, for example, data indicating the position and shape of the eyes, eyebrows, nose, mouth, etc., and features such as the outline of the face. The facial feature point data can be generated based on the facial photograph provided by the user for registration in the user DB or the facial image data of the user captured for registration.

"First default destination floor" is information indicating the first default destination floor of the user specified by the "face data". As the first default destination floor, for example, the value of the floor where the user resides is set.

"Second default destination floor" is information indicating the second default destination floor of the user specified by the "face data". As the second default destination floor, for example, a value of a shared floor such as a restaurant floor is set.

In the example shown in FIG. 5, "12" and "13" are registered as the first default destination floor and the second default destination floor in association with the face data "face data 1". Also, "15" and "14" are registered as the first default destination floor and the second default destination floor in association with the face data "face data 2". For the rest of the face data, similarly, information on the first default destination floor and the second default destination floor is registered in association with the face data.

2. Elevator System Operation The operation of the elevator system will now be described in more detail with reference to flowcharts.

FIG. 6 is a flow chart explaining the operation of the destination floor registration device 30. As shown in FIG.

The control unit 31 of the destination floor registration device 30 causes the display unit 34 to display a face authentication destination floor registration screen (S10).

FIG. 7 is a diagram showing an example of a face authentication destination floor registration screen. On the face authentication destination floor registration screen, the entire area of the captured image captured by the face authentication camera 35 is displayed. The control unit 31 of the destination floor registration device 30 divides the captured image into two areas, a first area A1 and a second area A2, and performs face detection on each of the first area A1 and the second area A2. process. The first area A1 is arranged in the area on the right side of the captured image. The second area A2 is arranged on the left side of the captured image. Above the first area A1, a guide "1st destination floor registration" is displayed superimposed on the captured image. Above the second area A2, a guide "2nd destination floor registration" is displayed superimposed on the captured image. Between the first area A1 and the second area A2, a demarcation line Ld extending in the vertical direction is displayed so as to be superimposed on the captured image.

8A and 8B are diagrams showing an example of the face authentication destination floor registration screen. When the user wants to register the first default destination floor, as shown in FIG. 8A, the user moves left and right to adjust the standing position so that the user's face is displayed in the first area A1. On the other hand, when the user wants to register the second default destination floor, as shown in FIG. 8B, the user moves left and right to adjust the standing position so that the user's face is displayed in the second area A2. . In order to prevent face detection from being performed while the user is adjusting the standing position in the horizontal direction, face detection processing may be performed on the captured image when predetermined face detection conditions are met. good. For example, the moving speed of an object such as a face on a captured image may be detected, and face detection processing may be performed when the moving speed becomes equal to or less than a threshold speed. Alternatively, when the movement range of the moving object on the captured image is continuously within one of the first area A1 and the second area A2 for a predetermined time or longer, face detection processing is performed on the captured image. you can go

Returning to FIG. 6, the control unit 31 of the destination floor registration device 30 determines whether or not the captured image output from the face authentication camera 35 includes a face (S11). Specifically, face detection processing is performed on the image data of the captured image.

When the face is not included in the captured image (NO in S11), that is, when the face is not detected, the controller 31 of the destination floor registration device 30 executes the process of step S11 again.

If a face is included in the captured image (YES in S11), that is, if a face is detected, the control unit 31 of the destination floor registration device 30 determines that the detected face is included in the first area A1 of the captured image. (S12). That is, it is determined whether or not a face is detected within the first area A1 in the captured image.

If the detected face is included in the first area A1 of the captured image (YES in S12), the controller 31 of the destination floor registration device 30 sets 1 to the variable default related to the destination floor (S13). A value of 1 for the variable default means that the first default destination floor is designated as the destination floor.

If the detected face is not included in the first area A1 of the captured image (NO in S12), that is, if the detected face is included in the second area A2 of the captured image, destination floor registration is performed. The control unit 31 of the device 30 sets 2 to the variable default related to the destination floor (S14). A value of 2 for the variable default means that the second default destination floor is designated as the destination floor.

The control unit 31 of the destination floor registration device 30 generates an allocation request signal including the departure floor, face data, and default value, and transmits it to the group supervisory control device 10 (S15). The installation floor of the destination floor registration device 30 is used as the departure floor. The “face data” here may be face image data (face image data) or face feature point data (face feature point data), as long as the face of the user can be distinguished. However, in the following description, the “face data” is assumed to be face feature point data. Face data for transmission (facial feature point data) is acquired by analyzing the captured image when it is determined in step S11 that a face is included. By transmitting the facial feature point data to the group supervisory control device 10, the group supervisory control device 10 does not need the process of acquiring the facial feature point data from the image data of the captured image.

The control unit 31 of the destination floor registration device 30 determines whether or not the allocation result signal including the destination floor and the allocated elevator name has been received from the group supervisory control device 10 (S16).

When the allocation result signal is received (YES in S16), the control unit 31 of the destination floor registration device 30 causes the display unit 34 to display an allocation result guidance screen (S17).

FIG. 9 is a diagram showing an example of an allocation result guide screen. The assignment result guide screen of FIG. 9 illustrates a case where the first car is assigned to the 12th floor, which is the destination floor.

If the allocation result signal has not been received (NO in S16), the control unit 31 of the destination floor registration device 30 determines whether or not an error signal has been received from the group supervisory control device 10 (S18).

If no error signal has been received (NO in S18), the control unit 31 of the destination floor registration device 30 returns to the determination in step S16.

If an error signal has been received (YES in S18), the control unit 31 of the destination floor registration device 30 causes the display unit 34 to display an error screen (S19). The error screen is a screen for notifying that an elevator cannot be assigned to a user who has undergone face authentication.

FIG. 10 is a diagram showing an example of an error screen. In the example of the error screen in FIG. 10, it is displayed as "You cannot use the elevator."

FIG. 11 is a flow chart explaining the operation of the group supervisory control device 10. As shown in FIG.

The control unit 11 of the group supervisory control device 10 determines whether or not an allocation request signal has been received from the destination floor registration device 30 (S31).

If the allocation request signal has not been received from the destination floor registration device 30 (NO in S31), the control unit 11 of the group supervisory control device 10 executes the determination of step S31 again.

When an allocation request signal is received from the destination floor registration device 30 (YES in S31), the control unit 11 of the group supervisory control device 10 stores face data matching the face data included in the allocation request signal to a certain degree or more in the user DB. (S32). That is, face authentication is performed for the face associated with the face data included in the allocation request signal. Various known methods can be used to compare face data for this determination. For example, the face data (facial feature point data) included in the allocation request signal and each face data (facial feature point data) registered in the user DB are sequentially compared (verified) to obtain the matching rate. Then, it is determined whether face data having a matching rate equal to or higher than a predetermined matching rate with respect to the face data included in the allocation request signal is registered in the user DB. When face data having a matching rate equal to or higher than a predetermined matching rate is registered in the user DB, the control unit 11 of the group supervisory control device 10 controls the use of the face data (facial feature point data) included in the allocation request signal. It determines that the person (the user whose face has been detected) is a user registered in the user DB, and determines that face authentication has succeeded.

If face data that matches the received face data to a certain degree or more is not registered in the user DB (NO in S32), the control unit 11 of the group supervisory control device 10 outputs an error signal to the destination of the transmission source of the allocation request signal. It is transmitted to the floor registration device 30 (S39), and the process returns to step S31.

If face data that matches the received face data to a certain extent or more is registered in the user DB (YES in S32), the control unit 11 of the group supervisory control device 10 associates the face data with the registered face data. The data of the default destination floor where the passenger is present is acquired from the user DB (S33).

The control unit 11 of the group supervisory control device 10 determines whether or not the value of the variable default included in the allocation request signal is 1 (S34).

When the value of the variable default is 1 (YES in S34), the control unit 11 of the group supervisory control device 10 sets the value of the first default destination floor acquired from the user DB as the destination floor (S35).

If the value of the variable default is not 1, that is, if it is 2 (NO in S34), the control unit 11 of the group supervisory control device 10 sets the value of the second default destination floor acquired from the user DB as the destination floor. (S36).

The control unit 11 of the group supervisory control device 10 determines the assigned car for the departure floor included in the assignment request signal and the set destination floor (S37). A well-known technique or the like may be used to determine the optimum number of elevators to be assigned from among a plurality of elevators (numbers).

The control unit 11 of the group supervisory control device 10 transmits an allocation result signal including the destination floor and the allocated car name to the destination floor registration device 30 that transmitted the allocation request signal (S38).

3. Actions/Effects, etc. Actions/effects, etc. of the present embodiment will be described. When using the elevator of the present embodiment, the user first goes in front of the destination floor registration device 30 . Then, when it is desired to register the first default destination floor, as shown in FIG. 8A, the user moves in the horizontal direction and adjusts the standing position so that the own face is displayed in the first area A1 in the captured image. The destination floor registration device 30 performs face detection processing on the image captured by the face authentication camera 35, and when the face is detected, the destination floor (first default destination floor) associated with the first area A1 is selected by the user. An assignment request signal is sent to the group supervisory control device 10 to instruct the destination floor to be set. The group supervisory control device 10 assigns the first default destination floor to one of the elevators and transmits an assignment result signal indicating the assignment result to the group supervisory controller 10 . When the destination floor registration device 30 receives an allocation result signal regarding the allocation result from the group supervisory control device 10 as a response to the allocation request signal, the destination floor registration device 30 causes the display unit 34 to display an allocation result guidance screen. As a result, the user can perform destination floor registration for the first default destination floor out of the first default destination floor and the second default destination floor without performing any touch operation or the like on the destination floor registration device 30. to receive an elevator assignment.

On the other hand, when the user wants to register the second default destination floor, as shown in FIG. to adjust. The destination floor registration device 30 performs face detection processing on the image captured by the face authentication camera 35, and when the face is detected, the destination floor (second default destination floor) associated with the second area A2 is selected by the user. An assignment request signal is sent to the group supervisory control device 10 to instruct the destination floor to be set. The group supervisory control device 10 assigns the second default destination floor to one of the elevators and transmits an assignment result signal regarding the assignment result to the group supervisory controller 10 . When the destination floor registration device 30 receives an allocation result signal indicating the allocation result from the group supervisory control device 10 as a response to the allocation request signal, the destination floor registration device 30 causes the display unit 34 to display an allocation result guidance screen. As a result, the user can perform destination floor registration for the second default destination floor out of the first default destination floor and the second default destination floor without performing any touch operation or the like on the destination floor registration device 30. to receive an elevator assignment.

Here, conventionally, there is a system in which a user can register a default destination floor by holding an ID card or the like over a card reader. However, if the passenger wants to go to a floor other than the default destination floor, it is necessary to register the destination floor using the destination floor registration device 30 equipped with a numeric keypad, etc., which poses a problem of convenience. However, according to the destination floor registration device 30 of the present embodiment, one destination floor registration device 30 can perform face authentication to register for an arbitrary destination floor out of the two default destination floors. Therefore, the convenience of destination floor registration can be improved. In addition, since there is no need to perform touch operations on the numeric keypad or the like, it is possible to suppress infections caused by viruses, bacteria, and the like.

(Embodiment 2)
Some users may think that only one default destination floor is sufficient. In this embodiment, an elevator system that considers such user convenience will be described.

12A and 12B are flowcharts explaining the operation of the destination floor registration device 30. FIG.

The control unit 31 of the destination floor registration device 30 causes the display unit 34 to display an initial screen (S51).

13A and 13B are diagrams showing an example of the initial screen. As shown in FIG. 13A, on the initial screen, only the characters "Destination floor registration" are displayed against the background of the captured image (live image) captured by the face authentication camera 35 . It should be noted that this is just an example, and supplementary information related to destination floor registration may be displayed together.

The control unit 31 of the destination floor registration device 30 determines whether or not the captured image output from the face authentication camera 35 includes a face (S52). Specifically, face detection processing is performed on the image data of the captured image. Note that during the initial screen display, the entire area of the captured image may be used as the face detection area, or a part of the area may be used as the face detection area. FIG. 13B shows a state where the face is included in the initial screen.

When the face is not included in the captured image (NO in S52), that is, when the face is not detected, the controller 31 of the destination floor registration device 30 executes the process of step S52 again.

If the captured image contains a face (YES in S52), that is, if a face is detected, the controller 31 of the destination floor registration device 30 sets 0 to the variable default for the destination floor (S53).

The control unit 31 of the destination floor registration device 30 generates an inquiry signal including the departure floor, face data, and default value, and transmits it to the group supervisory control device 10 (S54).

The control unit 31 of the destination floor registration device 30 determines whether or not a registration screen display command including information on the first default destination floor and the second default destination floor has been received from the group supervisory control device 10 (S55).

If the registration screen display command has not been received (NO in S55), the controller 31 of the destination floor registration device 30 has received an allocation result signal including the destination floor and the allocated car name from the group supervisory control device 10. (S57).

When the allocation result signal is received (YES in S57), the control section 31 of the destination floor registration device 30 causes the display section 34 to display an allocation result guidance screen (S58). The contents of the allocation result guide screen are the same as those described in the first embodiment.

If the allocation result signal has not been received (NO in S57), the control section 31 of the destination floor registration device 30 determines whether or not an error signal has been received from the group supervisory control device 10 (S59).

If no error signal has been received (NO in S59), the control unit 31 of the destination floor registration device 30 returns to the determination in step S55.

If an error signal has been received (YES in S59), the control unit 31 of the destination floor registration device 30 causes the display unit 34 to display an error screen (S60). The contents of the error screen are the same as those described in the first embodiment.

In step S55, when the registration screen display command is received (YES in S55), the control unit 31 of the destination floor registration device 30 causes the display unit 34 to display the face authentication destination floor registration screen (S56), and after step S11. is executed in the same manner as in the first embodiment.

14A and 14B are diagrams showing an example of a face authentication destination floor registration screen according to Embodiment 2. FIG. The face authentication destination floor registration screen of FIG. 14A is displayed following the initial screen as illustrated in FIG. 13B. Therefore, when the face position on the initial screen is at the position illustrated in FIG. 13B, the user's face is displayed across the first area A1 and the second area A2 on the face authentication destination floor registration screen of FIG. 14A. It will be done. In such a case, the user should change the standing position to the area side of the default destination floor to be registered. For example, if the default destination floor to be registered is the 13th floor, as shown in FIG. 14B, it is sufficient to move left and right to adjust the standing position so that the user's face is displayed in the second area A2. . Depending on the user's standing position at the time of face authentication, the user's face may be located in the default destination floor area that the user does not want when the face authentication destination floor registration screen is displayed. In such a case, if face detection processing is performed immediately, a default destination floor different from the user's intention may be registered. In order to avoid this, for example, the following processing may be performed. That is, the face authentication destination floor registration screen is displayed (step S56) so that face authentication processing is not performed until the user moves to a desired area between the first area A1 and the second area A2. The face detection process (step S11 in FIG. 12B) may be executed after a predetermined time (for example, after an arbitrary time between 1 second and 3 seconds).

Here, in the face authentication destination floor registration screen of FIG. 14A, face detection and face authentication are performed instead of the display of "first destination floor registration" and "second destination floor registration" on the face authentication destination floor registration screen of FIG. Destination floor guidance "13th floor registration" indicating the user's first default destination floor and "14th floor registration" indicating the second default destination floor are displayed. The values of the first default destination floor and the second default destination floor are displayed based on the information of the first default destination floor and the second default destination floor included in the registration screen display command. Since the values of the user's first default destination floor and second default destination floor are displayed in this manner, the user's erroneous registration of the first default destination floor and second default destination floor is suppressed. .

FIG. 15 is a flow chart explaining the operation of the group supervisory control device 10. As shown in FIG.

In the flowchart of FIG. 15, steps S71, S72, and S73 are added to the flowchart of FIG. Steps S31A, S37A, S38A, and S39A are provided in place of steps S31, S37, S38, and S39 in the flowchart of FIG.

At step S31A, the control unit 11 of the group supervisory control device 10 determines whether or not an inquiry signal or an allocation request signal has been received from the destination floor registration device 30 (S31A).

If neither the inquiry signal nor the allocation request signal has been received from the destination floor registration device 30 (NO in S31A), the control unit 11 of the group supervisory control device 10 executes the determination of step S31A again.

When the inquiry signal or the allocation request signal is received from the destination floor registration device 30 (YES in S31A), the control unit 11 of the group supervisory control device 10 executes the processes of steps S32 and S33 as in the first embodiment.

The control unit 11 of the group supervisory control device 10 determines whether or not the value of the variable default included in the inquiry signal or allocation request signal is 0 (S71).

When the value of the variable default is 0 (YES in S71), the control unit 11 of the group supervisory control device 10 determines whether or not the data acquired from the user DB includes the data of the second default destination floor. (S72).

If the data of the second default destination floor is not included (NO in S72), the control section 11 of the group supervisory control device 10 executes the processes after step S35.

If the data of the second default destination floor is included (YES in S72), the control unit 11 of the group supervisory control device 10 issues a registration screen display command including the information of the first default destination floor and the second default destination floor. It is transmitted to the destination floor registration device 30 which is the transmission source of the allocation request signal (S73). Upon receiving the registration screen display command, the destination floor registration device 30 causes the display unit 34 to display the face authentication destination floor registration screen of FIG. 14 described above.

If the value of the variable default is not 0 (NO in S71), the control section 11 of the group supervisory control device 10 determines whether or not the value of the variable default included in the allocation request signal is 1 (S34).

When the value of the variable default is 1 (YES in S34), the control unit 11 of the group supervisory control device 10 sets the value of the first default destination floor acquired from the user DB as the destination floor (S35).

If the value of the variable default is not 1, that is, if it is 2 (NO in S34), the control unit 11 of the group supervisory control device 10 sets the value of the second default destination floor acquired from the user DB as the destination floor. (S36).

At step S37A, the control section 11 of the group supervisory control device 10 determines the assigned car for the departure floor and the set destination floor included in the inquiry signal or the assignment request signal (S37A).

In step S38A, the control unit 11 of the group supervisory control device 10 transmits an allocation result signal including the destination floor and the allocated elevator name to the destination floor registration device that transmitted the inquiry signal or the allocation request signal (S38A).

In step S39A, the control unit 11 of the group supervisory control device 10 transmits an error signal to the destination floor registration device that is the transmission source of the inquiry signal or allocation request signal (S39A).

Actions/effects and the like of the present embodiment will be described. When using the elevator of this embodiment, the user first goes in front of the destination floor registration device 30 . Then, face authentication is performed on the initial screen of FIG. 13A. When standing in front of the destination floor registration device 30, the user's face imaged by the face authentication camera 35 is displayed on the display unit 34, for example, as shown in FIG. 13B, and face detection is performed by face detection processing. . When the face is detected, the destination floor registration device 30 transmits an inquiry signal including 0 as the value of the variable default to the group supervisory control device 10 . When two default destination floors are not registered in the user DB in association with the detected face, that is, when only the first default destination floor is registered, the group supervisory control device 10 selects the first default destination A floor is assigned to one of the elevators and an assignment result signal is sent to the group supervisory control device 10 . When the destination floor registration device 30 receives the assignment result signal from the group supervisory control device 10 as a response to the inquiry signal including 0 as the value of the variable default, the display unit 34 displays the following message as shown in FIG. Display the allocation result screen. As a result, the user can perform destination floor registration for the first default destination floor and receive an elevator assignment without performing any touch operation or the like on the destination floor registration device 30 .

On the other hand, if two default destination floors are registered in the user DB in association with the detected face, the group supervisory control device 10 registers information on the first default destination floor and the second default destination floor. A registration screen display command containing the information is transmitted to the destination floor registration device 30 that is the transmission source of the inquiry signal. The destination floor registration device 30 that has received the registration screen display command causes the display unit 34 to display the face authentication destination floor registration screen.

According to the destination floor registration device 30 of the present embodiment, when the number of registered default destination floors can be selected from 1 or 2, for a user who has registered only one default destination floor, , the destination floor registration of the default destination floor can be performed only by performing general face authentication, without adjusting the standing position for selecting the default destination floor.

As described above, the convenience of destination floor registration can be improved in this embodiment as well. In addition, since there is no need to perform touch operations on the numeric keypad or the like, it is possible to suppress infections caused by viruses, bacteria, and the like.

(Other embodiments)
In the above-described embodiment, two default destination floors can be registered in the user DB for each user, and the captured image is divided into two regions, but the present invention is not limited to this. A predetermined number of three or more default destination floors may be registered in the user DB for each user, and the captured image may be divided into the predetermined number of areas. When dividing into three regions, the captured image may be divided into three regions, for example, a left region, a left and right intermediate region, and a right region.

In Embodiment 2, one or two default destination floors can be registered in the user DB for each user. shows an example of dividing a captured image into two. However, the invention is not so limited. An arbitrary number of default destination floors can be registered in the user DB for each user, and the captured image may be divided into a number corresponding to the number of registered default destination floors for each user. That is, the number of divisions may be variable according to the user.

In the first embodiment, the case where the first default destination floor and the second default destination floor are different floors has been described. However, in the user DB of Embodiment 1, the first default destination floor and the second default destination floor may be set to the same floor according to the user's request. In this case, the same floor is registered as the destination floor regardless of whether the user performs face authentication in the first area A1 or the second area A2. By configuring in this way, as in the second embodiment, convenience for users who think that it is sufficient to set only one default destination floor is improved.

In the above embodiment, an example was explained in which the same thing is applied as the first default destination floor and the second default destination floor regardless of the departure floor. However, the present invention is not limited to this. It may be possible to make the first default destination floor and the second default destination floor different for each departure floor. In this case, the first default destination floor and the second default destination floor for each departure floor may be registered in the user DB. For example, if the departure floor is the lobby floor (for example, the 1st floor), register the work floor or restaurant floor where the user works as the first default destination floor and the second default destination floor. In some cases, the lobby floor (for example, the first floor) and the restaurant floor may be registered as the first default destination floor and the second default destination floor. In the case where the first default destination floor and the second default destination floor are different for each departure floor in this way, the configuration of the second embodiment is adopted, and destination floors corresponding to each region are added to each of the n regions. may be displayed. This makes it difficult for the user to misunderstand the destination floor for each area.

In the above embodiment, the user DB is stored in the storage unit 12 of the group control device 10, but depending on the building, a security system using face authentication may be provided. Such a security system usually has a database that stores face data for face authentication and the like. Therefore, the first default destination floor and the second default destination floor are registered in association with the face data of this database, and the group supervisory control device 10 selects the first default destination floor and the second default destination floor from this database. You can also get the value of

In the above-described embodiment, the destination floor registration device 30 is arranged on the elevator hall of each floor or on the wall surface of the building in the vicinity thereof. A registration device 30 may be arranged. In this case, the opening and closing of the flapper of the security gate may be controlled based on the face recognition result in the group supervisory control device 10 .

In the above embodiment, the case where the "face data" is facial feature point data has been specifically described. However, the invention is not so limited. The “face data” may be face image data. The format of the image data may be any format such as bmp format, jpg format, gif format, or the like. When "face data" is used as image data, face image data may be registered as "face data" in the user DB. In step S15 of FIG. 6, the destination floor registration device 30 transmits an allocation request signal including face image data as "face data" to the group supervisory control device 10. FIG. The image data of the face is acquired from the captured image, for example, when it is determined that the face is included in step S11. Upon receiving the assignment request signal, the group supervisory control device 10 determines whether or not face data matching the face data included in the assignment request signal to a certain extent or more is registered in the user DB (S32). For example, the face data (face image data) included in the allocation request signal and each face data (face image data) registered in the user DB are sequentially compared (verified) to obtain the match rate. Then, it is determined whether face data having a matching rate equal to or higher than a predetermined matching rate with respect to the face data included in the allocation request signal is registered in the user DB. When face data having a matching rate equal to or higher than a predetermined matching rate is registered in the user DB, the control unit 11 of the group supervisory control device 10 identifies the user associated with the face data (face image data) included in the allocation request signal. It is determined that (the user whose face has been detected) is a user registered in the user DB, and it is determined that face authentication has succeeded.

Although the elevator system having a plurality of elevators 60 is illustrated in the above embodiment, the present invention is also applicable to an elevator system having a single (one) elevator.

In each of the above-described embodiments, the control unit of each device is configured using a CPU, MPU, etc., and performs arithmetic processing using various data based on a program read from the storage unit to perform various operations. to realize the function of That is, each control unit is realized by cooperation of hardware and software. However, each control unit may be configured using, for example, only hardware (electronic circuit), FPGA, ASIC, or the like.

In each of the embodiments described above, the network is Ethernet, and the input/output interface of each device is configured using a LAN adapter or the like. However, this is only an example, and the network may be configured by, for example, a wireless LAN conforming to the IEEE standard, and the input/output interface may be configured by a wireless LAN adapter or the like.
