The storage device 30 is connected to the control device 40 by wire or wirelessly so that the storage content can be read by the control device 40 .

The control board 25 is connected to the control device 40 so as to be able to transmit and receive various signals. The control panel 25 and the control device 40 may be arranged as independent devices and connected wirelessly. Also, the control device 40 may be incorporated inside the control panel 25 .

The control panel 25 acquires position information indicating the current position of the car 10 from the car position detector 24 during normal operation of the elevator. Further, the control panel 25 drives the drive device 21 based on the position information acquired from the car position detection device 24, for example, to move the car 10 to a desired destination floor.

As described above, the car position detection device 24 detects the position of the car 10 in the hoistway 26 based on the drive amount of the drive device 21 represented by the number of revolutions of the hoisting machine, for example. The car position detection device 24 also generates position information about the position of the car 10 . The generated position information is acquired by the control panel 25 .

The driving device 21 drives the car 10 in the hoistway 26 by being driven by itself. At this time, the driving device 21 is driven according to the control amount received from the control panel 25 . As a result, the car 10 moves in the direction based on the control amount by the distance corresponding to the control amount.

The car 10 is provided with an imaging device 11 , a sound collector 12 and an output device 13 . The imaging device 11, the sound collecting device 12, and the output device 13 may each be one, or a plurality of them.

The imaging device 11 images the inside of the elevator car 10 . For example, the imaging device 11 is a camera. For example, the imaging device 11 is installed on the ceiling of the car 10 or a wall surface near the ceiling.

In the embodiment, imaging device 11 is used to capture an image of the user's face. The image of the user's face captured by the imaging device 11 is used for analysis by the control device 40, which will be described later. By providing a plurality of imaging devices 11 in the car 10, it is possible to reduce blind spots and more reliably capture images of the user's face.

The sound collector 12 collects sounds inside the car 10 . For example, the sound collection device 12 is a microphone.

The output device 13 is provided inside the car 10 and outputs image information as provided information. For example, the output device 13 is a projector that projects an output image onto the wall surface 14 of the car 10 .

FIG. 2 is a block diagram illustrating a configuration example of a storage device and a control device according to the embodiment; The storage device and control device are configured as a computer including, for example, a CPU (Central Processing Unit), a ROM (Read Only Memory), and a RAM (Random Access Memory).

As shown in FIG. 2, the storage device 30 stores user information 31 . User information 31 includes authentication information 311 and image information 312 .

The authentication information 311 includes information such as an ID for identifying the user and information for recognizing the user. The authentication information 311 is an example of user identification information.

For example, information for recognizing a user is information representing facial features of each user, and an image recognition model created by a machine learning technique such as deep learning is used to recognize the user.

Also, the ID for identifying the user may be information such as a room number identifying a resident of the housing complex in which the elevator system 1 is installed. In this case, the user of the elevator can be identified by associating the key with the room number and obtaining the open/close status of the key in the auto-lock system of the housing complex.

The image information 312 is an image associated with the user's authentication information 311 . A user's favorite image can be used as the image information 312 . The image information 312 may be a moving image, a still image, or a combination of audio and images. Instead of the image information 312 to be provided, information specifying the image information 312 to be provided, for example, information indicating a link to the storage location of the image information 312 may be registered as provided information. good too.

A user can register a favorite image in advance as the image information 312 via a mobile terminal or the like (for example, a smartphone). If the user is a child, the image information 312 may be registered by the child's guardian.

In addition, the user may select a specific image and register it in the storage device 30 in advance as image information, or may register some information about the image (for example, a character appearing in an animation).

As described above, in the embodiment, the user can preliminarily register his/her favorite provided information regardless of his/her attributes, and can receive the registered provided information inside the car 10 .

The control device 40 has an analysis section 41 and a control section 42 . For example, a program stored in a ROM or the like is read out, developed in a RAM, and executed by the CPU, thereby realizing the functions of the analysis unit 41 and the control unit 42 described above. The control device 40 also controls the output device 13 .

The analysis unit 41 determines whether or not there is a registered user inside the car 10 from the image captured by the imaging device 11 .

For example, the analysis unit 41 uses a trained image recognition model to determine the degree of matching between the features of the face captured in the image captured by the imaging device 11 and the features of the user's face stored in the storage device 30. If the degree of matching is equal to or greater than the threshold value, it is determined that a registered user is inside the car 10 .

The analysis unit 41 analyzes the image captured by the imaging device 11 and the sound collected by the sound collector 12, and determines whether or not the user inside the car 10 feels uncomfortable.

The analysis unit 41 recognizes the image captured by the imaging device 11 or the sound collected by the sound collector 12, and detects the behavior of the user. Then, the analysis unit 41 determines that the user feels uncomfortable when a specific action is detected.

For example, when the analysis unit 41 detects that the size of the user's movement is equal to or greater than a predetermined size from the image captured by the imaging device 11, the analysis unit 41 detects that the user is frowning from the image. When detected, at least when it is detected that the user is crying from the sound collected by the sound collection device 12, and when it is detected that the user is sighing from the sound In either case, it is determined that the user has discomfort.

When the analysis unit 41 determines that the user is uncomfortable, the control unit 42 outputs the image information 312 stored in the storage device 30 in association with the user's authentication information to the output device 13. Let The control unit 42 terminates the image output when the user who feels discomfort gets off the car 10 .

In this way, the control device 40 provides the image information (favorite image) registered in advance for each user when the user feels uncomfortable inside the elevator car, thereby reducing the discomfort. can be reduced.

(Modification 1)
The analysis unit 41 may detect, from the image captured by the imaging device 11 , the line-of-sight direction of the user determined to have discomfort. In this case, the control unit 42 causes the output device 13 to project and display the image information 312 on the wall surface of the car 10 that is in the line of sight of the user.

FIG. 3 is a diagram for explaining a method of outputting the image information 312. As shown in FIG. A wall surface 14N, a wall surface 14E, a wall surface 14S, and a wall surface 14W in FIG. 3 are located to the north, east, south, and west of the car 10, respectively. A sheet on which the projector can project an image may be attached to the wall surface.

In the example of FIG. 3, the analysis unit 41 detects that the user is facing west. Then, the analysis unit 41 causes the image to be projected and displayed on the wall surface 14W on the west side.

For example, when a child is crying with discomfort, even if the favorite image information 312 is projected on a specific wall surface, the child may not immediately calm down and face that direction. As in Modification 1, by projecting and displaying an image on the wall surface in the direction the user is facing, the image can be more reliably shown to the user.

(Modification 2)
A plurality of output devices 13 for outputting images may be provided inside the car 10 . In this case, the analysis unit 41 determines that the users inside the car 10 are uncomfortable.

Then, the control unit 42 causes each of the plurality of output devices 13 to output the image information 312 stored in the storage device 30 in association with the authentication information of different users among the plurality of users. For example, the control unit 42 may project and display different images on a plurality of wall surfaces inside the car 10 .

Accordingly, even when a plurality of users are feeling discomfort at the same time, it is possible to provide an image suitable for each user.

Furthermore, when it is determined that a plurality of users are feeling discomfort at the same time, the control unit 42 may alternately output images associated with each user.

Further, the control unit 42 may output an image associated with a user having the greatest degree of discomfort among a plurality of users having discomfort. This is because the behavior of a user with a high degree of discomfort may increase the discomfort of other users.

(Modification 3)
The user can select and register an image stored in the mobile terminal when registering the call of the car 10 . The registered image is provided when it is determined that the user feels uncomfortable inside the car 10 .

At this time, the portable terminal transmits the image selected by the user to the storage device 30 when the call registration of the car 10 is performed at the boarding point. Then, the storage device 30 associates and stores the user's authentication information and the image information 312 .

Thereby, the user can register the image information according to the mood just before getting on the elevator.

(Modification 4)
The storage device may be provided on a network connected to the control device. For example, as shown in FIG. 4, the storage device 30a is provided to be connected to a network N connected to the control device 40. FIG. FIG. 4 is a diagram showing a configuration example of an elevator system according to a modification. The elevator system in Modification 4 is assumed to be an elevator system 1a. The storage device 30 a has the same configuration as the storage device 30 .

In this case, the control unit 42 outputs the image information 312 acquired from the storage device 30a via the network N. FIG. Network N is, for example, the Internet.

This allows the user to register image information from outside the building 2 . Also, an elevator system installed in a building different from the building 2 can refer to the storage device 30a.

As shown in FIG. 5, first, the control device 40 acquires an image and sound inside the car (step S101). Next, the control device 40 recognizes the user's face from the acquired image (step S102).

As a result of recognition, if the registered user is not shown in the image (step S103, No), the control device 40 terminates the process.

As a result of recognition, if a registered user appears in the image (step S103, Yes), the control device 40 determines whether or not the user inside the car feels uncomfortable based on the image and sound. (step S104).

For example, the control device 40 determines that the user has discomfort when a specific behavior of the user is detected from the acquired image or sound. For example, specific behaviors include large body movements (swaying, writhing, squatting), grimacing, crying, sighing, making high-pitched sounds (screams, strange sounds), and the like.

If the control device 40 determines that the user does not feel discomfort (step S105, No), the process ends.

On the other hand, when the control device 40 determines that the user feels uncomfortable (step S105, Yes), the control device 40 outputs the image associated with the user to the output device 13 installed in the car 10 ( step S106).

The analysis unit 41 analyzes the image captured by the imaging device 11 and the sound collected by the sound collector 12, and determines whether or not the user inside the car 10 feels uncomfortable. When the analysis unit 41 determines that the user is uncomfortable, the control unit 42 selects the provision object (for example, the image information 312) stored in the storage device 30 in association with the user's authentication information. is output to the output device 13 .

In this way, the elevator system 1 outputs the provision target (for example, the image information 312) registered in advance for each user when the user feels uncomfortable. As a result, it is possible to provide an object to be provided that matches the preference of the elevator user, thereby reducing discomfort.

Further, when the analysis unit 41 detects that the size of the user's movement is greater than or equal to a predetermined size from the image captured by the imaging device 11, the analysis unit 41 detects that the user frowns from the image. When detected, at least when it is detected that the user is crying from the sound collected by the sound collection device 12, and when it is detected that the user is sighing from the sound In either case, it is determined that the user has discomfort.

Thereby, it is possible to automatically determine whether or not the user feels discomfort from the image and sound.

The analysis unit 41 detects the line-of-sight direction of the user determined to have discomfort from the image captured by the imaging device 11 . The control unit 42 causes the output device 13 to project and display the image information 312 on a wall surface of the car 10 that is in the line of sight of the user.

As a result, it is possible to more reliably show the image to the user who feels discomfort.

A plurality of output devices 13 are provided inside the car 10 for outputting the object to be provided such as the image information 312 . The analysis unit 41 determines that a plurality of users inside the car 10 have discomfort. The control unit 42 causes each of the plurality of output devices 13 to output the object to be provided such as the image information 312 stored in the storage device 30 in association with the authentication information of different users among the plurality of users.

As a result, it is possible to simultaneously output image information and other objects to be provided to a plurality of users who feel discomfort, thereby alleviating the discomfort of each user.

The mobile terminal transmits to the storage device 30 the object to be provided such as the image information 312 selected by the user when the call registration of the car 10 is performed at the boarding point. The storage device 30 associates a user with an object to be provided such as image information 312 and stores them.
