  The car 10 includes a car operation panel 13, a camera 14 </ b> A, an authentication device 15, and a speaker 16. The car operation panel 13 is installed in the car 10 and registers a destination floor and opens and closes the car door 11. The car operation panel 13 includes a destination floor button 13 a for registering a destination floor and an opening / closing button (not shown) for opening and closing the car door 11. The car operation panel 13 is connected to the operation control unit 60 and outputs an operation signal generated by a user operation to the operation control unit 60.

  The camera 14 </ b> A is a photographing unit and photographs the face of a user who gets on the car 10. The camera 14 </ b> A is installed in the car 10. For example, as shown in FIG. 4, the camera 14 </ b> A is installed in the vicinity of the ceiling on the back side in the depth direction of the car 10, and photographs the inside of the car 10 from the back side of the car 10 toward the car door 11. The camera 14 </ b> A may be installed at the landing 4 to capture the face of the user who stands by in front of the car door 11. The camera 14 </ b> A is connected to the authentication device 15 and outputs the captured video to the authentication device 15.

  The authentication device 15 determines a user who can use the elevator 1 based on the video output from the camera 14A. The authentication device 15 includes a storage unit 15a and a determination unit 15b.

  The storage unit 15 a stores information on users who can use the elevator 1. User data T shown in FIG. 3 is stored in the storage unit 15a. The user data T includes items indicating an identification ID, a reference face image, a classification, an available floor, and a registration date, and is set for each user. The identification ID is a number for identifying the user. The reference face image is an image obtained by photographing the face of a user who can use the elevator 1. The category indicates a user attribute. For example, when a building is a condominium, a resident or a visitor is set in the category. Here, the resident is a user who lives in the apartment, and the visitor is a user other than the resident of the apartment. An available floor is a floor that a user can use. When a user registers a destination floor by using the destination floor button 13a of the car operation panel 13, the user can register only the floor set as an available floor. The registration date is the date when the user data T of the user is registered. The storage unit 15a is connected to a user management device (not shown), and user data T is input from the user management device for each user.

  The user management apparatus is installed in a manager room of a building, for example, and registers user data T. The user management apparatus registers the identification ID, reference face image, classification, and registration date of the user who uses the elevator 1 for each user. For example, when the building is a condominium, each item of the user data T is registered for all residents.

  The determination unit 15 b determines a user who can use the elevator 1. For example, the determination unit 15b compares the user's captured face image captured by the camera 14A with the user's reference face image stored in the storage unit 15a, and the user's captured face image is determined based on the comparison result. It is determined whether or not it matches the user's reference face image. The determination unit 15 b outputs the determination result to the operation control unit 60. Note that the determination unit 15b detects the user's face from the video imaged by the camera 14A using a face detection algorithm based on, for example, features of face parts such as eyes and nose and skin color. Further, the determination unit 15b determines the matching of the face images using, for example, a face recognition algorithm that compares the characteristics of the face parts.

  The speaker 16 is an audio output unit, and announces the user in the car 10 by audio. The speaker 16 is installed in the car 10 as shown in FIG. The speaker 16 is connected to the operation control unit 60 and receives a signal indicating that the announcement is executed from the operation control unit 60.

  The collective entrance machine 70 is a reception terminal and regulates entrance to the building. As shown in FIG. 6, the collective entrance machine 70 is installed at the entrance of the entrance 5 of the building and connected to the authentication device 15. The collective entrance machine 70 includes a camera 71 for photographing a visitor. The collective entrance machine 70 stores, in the storage unit 15 a of the authentication device 15, a reference face image of the visitor obtained by photographing the visitor's face with the camera 71 when permitting the visitor to enter the building. For example, the collective entrance machine 70 recognizes a user who enters the apartment by entering a room number of the apartment as a visitor, and recognizes a user who enters the building by a key operation as a resident.

  The determination unit 15b automatically deletes the reference face image of the visitor from the storage unit 15a when a predetermined condition is satisfied in order to reduce the capacity of the storage unit 15a. For example, the determination unit 15b acquires a date when the reference face image of the visitor is stored in the storage unit 15a, and stores the reference face image of the visitor in the storage unit 15a, and then after a certain period, for example, three months later. Delete the reference face image of the visitor.

  The determination unit 15b may delete a plurality of reference face images of the same visitor stored in the storage unit 15a. Parents, siblings and deliverymen living near the apartment are expected to visit the apartment frequently as visitors. In this case, each time the same visitor visits, approximately the same reference face image is created and stored in the storage unit 15a. Therefore, only the latest one may be left and the remaining old reference face images may be deleted. . For example, the determination unit 15b determines whether or not there is the same reference face image among the visitor's reference face images stored in the storage unit 15a. Only the new reference face image is left and the remaining reference face images are deleted. This deletion process is performed as a batch process in a time zone such as midnight when there are few in and out of the apartment.

  Next, an operation example of the elevator control device according to the embodiment will be described. FIG. 7 is a flowchart showing an operation example of the elevator control device. The storage unit 15a stores user data T in which residents of condominiums and visitors are registered.

  First, as shown in FIG. 7, the operation control unit 60 photographs the face of the user who gets on the car 10 with the camera 15 (step S1). For example, the operation control unit 60 outputs to the camera 15 a signal indicating that photographing is started at the timing when the car 10 has landed on the floor of the landing 4 and the car door 11 has been completely opened. The camera 15 shoots the face of the user who gets on the car 10 when a signal indicating the start of shooting is output from the operation control unit 60.

  Next, the determination unit 15b compares the user's captured face image captured by the camera 15 with the user's reference face image (step S2), and the user's captured face image becomes the user's reference face image. It is determined whether or not they match (step S3). For example, the determination unit 15b refers to the user data T stored in the storage unit 15a, and compares the reference face images of all users with the captured face images of the users. When determining that the photographed face image of the user does not match the reference face image of the user (step S3; YES), the determination unit 15b outputs a signal indicating that the photographed face image does not match the reference face image. 60. When the signal indicating that the captured face image does not match the reference face image is output, the operation control unit 60 waits for the car door 11 of the car 10 to be opened (step S4). Then, the operation control unit 60 controls the speaker 16 in the car 10 and announces that a user who is not permitted to use the elevator 1, that is, a suspicious person is getting on the car 10. (Step S5).

  The camera 15 continuously photographs the user who is on the car 10 while the car 10 is waiting for the door to open. The determination unit 15b marks a suspicious person who does not match the reference face image from the video imaged by the camera 15, and determines whether or not the suspicious person gets out of the car 10 (step S6). If the determination unit 15b determines that the suspicious person has not got off the car 10 (step S6; NO), the determination unit 15b returns to the above-described step S5 and again announces to urge the suspicious person to get off. In addition, when the determination unit 15b determines that the suspicious person got out of the car 10 (step S6; YES), driving control is performed to the effect that the photographed face image of the user in the car 10 matches the reference face image of the user. To the unit 60. The driving control unit 60 stops the announcement from the speaker 16 after the signal indicating that the photographed face image of the user in the car 10 matches the reference face image of the user is output from the determination unit 15b. The car door 11 is closed (step S7), and the car 10 is moved.

  If it is determined in step S3 described above that the photographed face image of the user matches the reference face image of the user and there is no suspicious person (step S3; NO), the operation control unit 60 causes the car 10 to The door 11 is closed (step S7).

  Further, when the user's photographed face image matches the user's reference face image in step S3 described above, the destination floor may be registered only on the floor that can be used by the user. For example, the determination unit 15b specifies a user from the reference face image, and outputs the available floor of the specified user to the car operation panel 13. The car operation panel 13 enables registration of the destination floor only for the usable floor output from the determination unit 15b. The car operation panel 13 performs destination floor registration in the operation control unit 60 when an available floor is designated by the user.

  Further, the available floor associated with the user may be automatically registered as the destination floor. For example, the car operation panel 13 automatically registers the available floor output from the determination unit 15b with the operation control unit 60 as the destination floor. The car operation panel 13 lights up the destination floor button 13a of the destination floor that has been automatically registered to clearly indicate that the destination floor has been registered.

  Moreover, when the time when a suspicious person does not get off from the car 10 elapses for a certain period of time in step S6 described above, an operator of a monitoring center (not shown) may be connected.

  As described above, according to the elevator control device according to the embodiment, when the user's photographed face image does not match the user's reference face image, the car 10 is put on standby. Thereby, it can prevent that a suspicious person moves the inside of a building using the elevator 1. FIG. Therefore, crime prevention can be improved.

  Since the suspicious person gets out of the car 10 until the suspicious person gets out of the car 10, it is announced by voice that the suspicious person in the car 10 can be prompted to get off. Since the suspicious person closes the car 10 immediately after getting off and returns to normal operation, the stop time of the elevator 1 can be minimized.

  In addition, when the user's captured face image matches the user's reference face image, only the available floor associated with the user can be registered as the destination floor. It is impossible to move to the next floor, and crime prevention can be improved. Further, if the available floor associated with the user is automatically registered as the destination floor, the user can save time and effort for registering the destination floor.

  Further, if the predetermined condition is satisfied, the reference face image of the visitor is automatically deleted from the storage unit 15a, so that the number of registered reference face images can be suppressed and the capacity of the storage unit 15a can be reduced. it can.

[Modification]
Next, a modification of the embodiment will be described. FIG. 8 is a schematic view showing another installation example of the camera in the car. As shown in FIG. 8, in addition to the camera 14 </ b> A installed near the ceiling on the back side in the depth direction of the car 10, a camera 14 </ b> B may be installed near the ceiling on the car door 11 side of the car 10. The camera 14 </ b> B images the inside of the car 10 from the car door 11 side toward the back side of the car 10. For example, the camera 14B photographs the user P1 in the car 10, and the camera 14A photographs the user P2 who gets into the car 10 and the user (suspicious person) P3. As described above, the cameras 14A and 14B may be installed so as to photograph from two directions, and the user P1 in the car 10 and the users P2 and P3 who get into the car 10 may be photographed.

  In addition, the user authentication is intended for all the landings 4, but is not limited to this. For example, the user may be authenticated only at the landing 4 installed at the entrance 5. If a suspicious person can be prevented from entering at the entrance 4 of the entrance 5, the suspicious person can be prevented from moving to the other floor of the building.

  In order to improve the processing speed of authentication, a priority order may be set for the user's reference face image to be compared with the user's captured face image. For example, the time zone in which a resident enters and exits a condominium often tends to have a certain tendency, such as a working time or a return time. The time zone in which the elevator 1 is used is recorded for each user, and the reference face image of the user who is likely to use the elevator 1 is compared in order at the time when the captured face image and the reference face image are compared. To do. As a result, the user's photographed face image and the user's reference face image coincide with each other at a stage where the number of comparisons is small, and the authentication processing speed can be improved.

  Moreover, you may apply to a special elderly nursing home as buildings other than an apartment. In this case, the user data T is registered with the caregiver or the staff as the resident and the family visiting the visit etc. as the visitor. Since the cared person does not register the user data T, the cared person cannot use the elevator 1. Thereby, for example, when a cared person suffers from dementia, the cared person can be prevented from hesitating and missing.

  Although the visitor's face image | photographed with the camera 71 of the entrance hall 70 was memorize | stored in the memory | storage part 15a as a reference | standard face image of a visitor, it is not limited to this. For example, a reference face image of a visitor captured in advance by a camera other than the camera 71 of the collective entrance machine 70 may be stored in the storage unit 15a.

  Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. These embodiments and their modifications are included in the scope and gist of the invention, and are also included in the invention described in the claims and the equivalents thereof.
