As shown in FIG. 2, the image analysis device 24 includes an image signal input unit 241 that inputs image signals photographed by the hall camera 22 and the car camera 23, and an image signal analysis unit 242 that analyzes the input image signals. And an analysis result storage unit 243 that stores the analysis result of the image signal, and an analysis result output unit 244 that outputs the analysis result to the elevator control device 50 and the like.

In this embodiment, when there is a child K among the elevator users, a lost child is efficiently prevented in cooperation with the building-side system.

Next, the processing procedure in 1st Embodiment is demonstrated using the flowchart of FIGS.

As shown in the flowchart of FIG. 3, during the normal operation of the elevator, the hall 4 on each floor is photographed by the hall camera 22 on each floor. The situation in the car 2 is photographed by the car camera 23 (steps S1 and S2).

Image signals from the landing camera 22 and the in-car camera 23 are input to the image signal analysis unit 242. The image signal analysis unit 242 analyzes the attributes of the user such as age, sex, height, face, clothes, facial expression, etc. by image processing in order to individually grasp the user from the input image signal, and the analysis The analyzed result is stored in the analysis result storage unit 243 (step S3).
Next, it is verified whether or not the child K exists in the analysis result. If the child K exists (step S4 YES), the tracking process shown in FIG. 4 is further executed. As a result, when behavior is detected, such as when getting off the connecting passage floor by one person (step S5 YES), getting on and off the same floor (step S6 YES), or crying in the car (step S7 YES) The lost child information is issued to a staff member on the floor where the child is lost or in the vicinity of the elevator on which the child is boarded (step S8). At the same time, the lost child information is displayed on the guidance display device provided on each floor (step S9). As this lost child information, the estimated age, height, sex, clothes, features, etc. of the child K are displayed. The image is also displayed as necessary.

As described above, according to the first embodiment, it is possible to detect a lost child effectively by image analysis using existing facilities such as the hall camera 22 and the car camera 23 installed in the elevator.

Second Embodiment
Next, a second embodiment will be described. Since the entire configuration of the elevator system shown in FIG. 1 and the block diagram shown in FIG. 2 are the same as those in the first embodiment, only the processing procedure will be described with reference to FIGS.

In the second embodiment, as shown in the flowchart of FIG. 3, the hall 4 on each floor is photographed by the hall camera 22 on each floor during normal operation of the elevator. The situation in the car 2 is photographed by the car camera 23 (steps S1 and S2).

Image signals from the landing camera 22 and the in-car camera 23 are input to the image signal analysis unit 242. The image signal analysis unit 242 analyzes the attributes of the user such as age, sex, height, face, clothes, facial expression, etc. by image processing in order to individually grasp the user from the input image signal, and the analysis The analyzed result is stored in the analysis result storage unit 243 (step S3).
Next, it is verified whether or not the child K exists in the analysis result. If the child K exists (step S4 YES), if the child K is on the board (step S11 YES) Then, it is determined whether or not the parent was accompanied at the time of entry (step S12). In this process, for example, the determination can be made from the result of the image processing of the building side monitoring camera 80 installed at the event venue or the entrance of the building. If the child is accompanied by the parent at the time of entry (YES in step S12), the child K is determined to be lost and user information is added to the lost child list from the user analysis data that is the analysis result of the image signal analysis unit 242 (step S13). ).

In this case, if a lost child application is installed on a mobile terminal (smartphone or tablet) possessed by the guardian of the child K, the lost child information is displayed by the lost child application (steps S14 and S15). If the mobile terminal with the application installed is not possessed (NO at step S15), it is displayed as lost child information on the guidance display device 90 installed at the hall 4 on each floor (step S16). When the guardian or the staff issues the lost child information by viewing the display content of the guidance display device 90 (step S17 YES), or the guardian issues the lost child information from the portable terminal by viewing the lost child information displayed on the portable terminal. If this is the case (steps S18, S19 YES), the lost child guidance operation is performed to protect the lost child (steps S20, S21).

For example, the disaster prevention center 70 that has received the lost child information notifies the elevator control device 50 to that effect, and drives the car to the floor where the lost child is located to protect the lost child. In this case, by using the hall speaker 42, anxiety is resolved by giving advice or guidance to the child K who is lost.

As described above, according to the second embodiment, it is possible to detect a lost child effectively by image analysis using existing facilities such as the hall camera 22 and the car camera 23 installed in the elevator. In addition, since the lost child information can be notified to the portable terminal possessed by the guardian, the elevator facility can be used safely and safely for the guardian.

In addition to the above embodiment, when the possibility of a lost child is recognized, the analysis result of the image signal of the hall camera 22 and the car camera 23 and the analysis result of the image signal of the building side monitoring camera 80 are linked. If configured to detect lost children, it becomes possible to detect lost children more effectively.
