Embodiment 2.
FIG. 6 is a block diagram of an elevator system according to Embodiment 2. FIG. The same reference numerals are given to the same or corresponding parts as those of the first embodiment. Description of this part is omitted.

As shown in FIG. 6, in the second embodiment, the human detection device 16 further includes an attribute detection section 16d.

The attribute detection unit 16d detects attributes of a person present in the detection area based on the information created by the recognition unit 16a. Specifically, the attribute detection unit 16d detects whether the person present in the detection area is an adult or a child. For example, when the human detection device 16 is a camera, the attribute detection unit 16d calculates the height of the person from the image of the person in the image captured by the camera. The attribute detection unit 16d determines that the person is an adult when the calculated height is greater than a prescribed value. Note that the attribute detection unit 16d may detect facial features of a person captured in an image captured by a camera, and determine that the person is an adult based on the facial features.

Note that the attribute detection unit 16 d may be provided in the control device 9 . In this case, the control device 9 receives information created by the recognition unit 16 a from the human detection device 16 . In the control device 9, the attribute detection section 16d detects the attributes of the person existing in the detection area based on the information created by the recognition section 16a.

The attribute detection unit 16d creates information in which the number of persons present in the detection area, the number of adults, and the number of children are associated with each other.

The transmission unit 16c transmits the information created by the attribute detection unit 16d to the control device 9 instead of the information created by the number detection unit 16b.

In the second embodiment, the determination unit 9e of the control device 9 receives information in which the number of people present in the detection area, the number of adults, and the number of children are associated with each other from the human detection device 16 via the communication unit 9a. to get

The determination unit 9e uses the number of adults present in the detection area rather than the number of people present in the detection area for the determination. Specifically, the determination unit 9e determines whether or not the number of security keys 12 present in the detection area matches the number of adults present in the detection area. If the number of security keys 12 present in the detection area does not match the number of adults present in the detection area, the determination unit 9e causes the control device 9 to transition from the normal mode to the warning mode.

According to the second embodiment described above, the control device 9 may further include the attribute detection section 16d. The control device 9 detects the number of adults in the detection area. The control device 9 determines whether or not the security key 12 present in the detection area matches the number of adults. Therefore, the number of children can be excluded from the number of persons to be compared with the number of security keys 12 . As a result, when the user is a family member, it is possible to suppress the notification of the warning.

Further, when the number of security keys 12 present in the detection area is equal to or greater than the number of adults, control device 9 determines that the number of security keys 12 matches the number of adults. For example, when one adult and one child each possess the security key 12, it is possible to prevent the control device 9 from issuing a warning.

The display unit 9d may cause the display device 13 to display the number of adults present in the detection area.

Even when the human detection device 16 is a weighing device, the human detection device 16 may include the attribute detection unit 16d. In this case, the attribute detection unit 16d may detect the number of adults and the number of children present in the detection area based on the information on the weight change inside the car 7 generated by the recognition unit 16a. The attribute detection unit 16d may detect that an adult has boarded the vehicle when the amount of increase in weight is greater than a specified value. Specifically, when the weight of the car 7 increases by 15 kg after increasing by 70 kg, the attribute detection unit 16d detects that one adult and one child are present inside the car 7, which is the detection area. may

Embodiment 3.
7 is a block diagram of an elevator system according to Embodiment 3. FIG. The same reference numerals are given to the same or corresponding parts as those of the first embodiment. Description of this part is omitted.

In Embodiment 3, the human detection device 16 is a camera. The camera, which is the human detection device 16, transmits information of the photographed image to the control device 9 at arbitrary timing.

As shown in FIG. 7, the control device 9 includes a storage section 9h, a characteristic detection section 9i, and a suspicious person determination section 9j.

The storage unit 9h stores suspicious person characteristic information. Suspicious person characteristic information is information indicating the characteristics of a person set as a suspicious person. For example, the suspicious person characteristic information indicates the appearance characteristics such as the height, clothes, face, etc. of the person set as the suspicious person. For example, the control device 9 acquires suspicious person characteristic information from an external information system and stores it in the storage unit 9h in advance. For example, the control device 9 acquires suspicious person characteristic information about suspicious persons reported in an area where a building exists from an external information system, and stores it in the storage unit 9h.

The feature detection unit 9i acquires information of an image captured by the human detection device 16. FIG. The feature detection unit 9i detects the features of the person by analyzing the image of the person in the image. Specifically, the feature detection unit 9i detects features of the person's appearance such as height, clothing, face, and the like. The feature detection unit 9i creates feature information indicating the detected features of the person.

When the communication unit 9a receives the authentication information, the suspicious person determination unit 9j acquires the feature information about the person appearing in the image information transmitted from the person detection device 16 from the feature detection unit 9i. After that, the suspicious person determination unit 9j determines whether or not the suspicious person characteristic information stored in the storage unit 9h matches the characteristic information. For example, when the match ratio between the suspicious person characteristic information and the characteristic information exceeds a prescribed threshold value, the suspicious person determination unit 9j determines that the suspicious person characteristic information and the characteristic information match.

If the suspicious person characteristic information and the characteristic information do not match, the suspicious person determination unit 9j terminates the determination. After that, the determination operation of the determination unit 9e is performed.

If the suspicious person characteristic information matches the characteristic information, the suspicious person determination unit 9j causes the control device 9 to transition from the normal mode to the suspicious person warning mode.

In the suspicious person warning mode, the warning notification unit 9f causes the display device 13 to display information indicating a warning that a suspicious person is present. In the suspicious person warning mode, the warning reporting unit 9f causes the warning device 14 to report the presence of a suspicious person. In the suspicious person warning mode, the operation control unit 9b controls the car 7 in the same manner as in the warning mode.

For example, when the canceling unit 9g detects that the user has performed a specific cancellation action while the control device 9 is in the warning mode, the canceling unit 9g changes the control device 9 from the suspicious person warning mode to the normal mode.

Next, operations performed in the elevator system 1 according to Embodiment 3 will be described with reference to FIGS. 8 and 9. FIG.
FIG. 8 is a flow chart for explaining the outline of the operation of the elevator system according to the third embodiment. FIG. 9 is a flow chart for explaining the outline of the operation of the elevator system according to the third embodiment.

After step S104, the operation of step S105 is performed. In step S<b>105 , the control device 9 creates human characteristic information based on the image captured by the human detection device 16 .

After that, the operation of step S106 is performed. In step S106, the control device 9 determines whether or not the suspicious person characteristic information matches the characteristic information.

If it is determined in step S106 that the suspicious person characteristic information matches the characteristic information, the operation of step S107 is performed. In step S107, the control device 9 transitions from the normal mode to the suspicious person warning mode. In the suspicious person warning mode, the control device 9 causes the display device 13 to display a warning. In the suspicious person warning mode, the control device 9 causes the alarm device 14 to issue a warning.

After that, the operation of step S108 is performed. In step S108, the control device 9 determines whether or not the user's unlocking action has been detected.

In step S108, when no cancellation action is detected, the control device 9 repeats the operation of step S108.

If it is determined in step S106 that the suspicious person characteristic information and the characteristic information do not match, or if a cancellation action is detected in step S108, the operations after step S109 are performed. As shown in FIG. 9, in steps S109 to S115, the same operations as steps S005 to S011 of the flowchart in FIG. 4 of the first embodiment are performed.

According to Embodiment 3 described above, the control device 9 further includes a storage section 9h, a feature detection section 9i, and a suspicious person determination section 9j. The control device 9 compares the features of the person present in the detection area with the features of the suspicious person stored in advance.
