It is a flowchart which shows a process sequence.

  As shown in FIG. 8, the security device according to the second embodiment includes a security camera 11 provided in a car, a control unit 12 connected to the security camera 11 and performing overall control of the device, and the control unit 12. For example, a monitor 13 provided in a management room of a building (not shown) for displaying an image in the car and a speaker 14 that is connected to the control means 12 and issues an alarm in the car are provided.

  Further, the control means 12 compares the difference between the image storage unit 12A for storing a background image when no passenger is present, the image captured by the security camera 11 and the image recorded in the image storage unit 12A, The image processing unit 12B that determines the presence or absence of the passenger and the predetermined area of the car, that is, the number of passengers in the security area, the area setting unit 12C that sets the security area based on the captured image, and the area setting unit 12C There is an area storage unit 12D for storing the set area, a communication unit 12E for reporting to the outside, for example, a control center (not shown), and a passenger authentication unit 12F for authenticating a specific passenger based on the image signal of the security camera 11. It is made up.

  The above-described passenger authentication means for authenticating a specific passenger is made up of, for example, the passenger authentication unit 12F, and the area storage means for storing in advance a predetermined area related to the specific passenger is made up of, for example, the area storage unit 12D. The area selecting means for selecting a predetermined area corresponding to the passenger authenticated by the passenger authenticating means from the area storing means comprises, for example, the image processing unit 12B. Similarly to the first embodiment described above, the area setting unit 12C serves as a predetermined area setting unit that presets a predetermined area based on the image signal of the security camera 11, and also includes an image processing unit 12B, a communication unit 12E, and a speaker 14. In the same manner as in the first embodiment, when at least two passengers are detected in a predetermined area on the basis of the image signal of the security camera 11, a notification means for issuing a warning is formed.

  First, in accordance with the same procedure as in the first embodiment described above, a predetermined area related to a specific passenger, that is, a security area is set while an image captured by the security camera 1 by the area setting unit 12C is displayed on the monitor 3 in advance. I do. For example, since a specific passenger 22 shown in FIG. 9 often uses an elevator together with a moving body, for example, a dog 22a, a relatively wide security area B is set, and this information is stored in the area storage unit 12D. On the other hand, since a specific passenger 23 shown in FIG. 10 often uses an elevator alone, a relatively narrow security area C is set, and this information is stored in the area storage unit 12D.

  Next, the processing procedure of the security device of the second embodiment will be described with reference to FIG. The passenger 22 registers a car call at the elevator hall, and when the car arrives, the passenger 22 gets into the car with the dog as step S11. At this time, the passenger authentication unit 12F authenticates the passenger 22 based on the image signal of the security camera 11 as step S12, and based on the authentication result, the image processing unit 12B sets the security area corresponding to the passenger 22 as the region storage unit 12D as step S13. Select from. Then, the passenger 22 registers the destination floor as shown in step S14, moves to the security area B as shown in FIG. 9 as step S15, and is set as step S17 when the door is closed as step S16. Security area B becomes valid and monitoring starts. Further, when another passenger 23 gets in during the movement to the destination floor registered by the passenger 22, that is, on the middle floor, the passenger 23 is authenticated in the same procedure as described above, as shown in FIG. The security area C corresponding to the passenger 23 is selected.

  By the way, while the security area B becomes effective in step S17 and the car heads to the destination floor, the image processing unit 12B has a passenger 22 and a dog 22a in the security area B based on the image signal of the security camera 11 as shown in step S18. Determine whether they are together. Then, when it is determined that, for example, the dog 22a protrudes from the security area B as shown in FIG. 11, a warning to that effect is issued by the speaker 14 in step S19 to call attention. Thereafter, when it is determined in step S20 that the dog 22a has returned to the security area B, the alarm is stopped in step S21, and the car is normally operated up to the destination floor as shown in step S22. Note that, after the security area B related to the passenger 22 and the security area C related to the passenger 23 become effective, for example, when one passenger enters the security area of the other passenger, the same as in the first embodiment described above. It goes without saying that the alarm in the car and the alarm to the control center are made in the procedure described above, and are omitted in the flowchart of FIG.

  According to the second embodiment configured as described above, when using a specific passenger's elevator, monitoring is performed based on the security area relating to the passenger stored in advance, so that the accuracy according to the use situation of each passenger can be improved. High monitoring is possible, and safety and convenience can be improved. In addition, when a mobile object belonging to a specific passenger, for example, a dog, protrudes from a predetermined security area, by notifying the fact by a notification means, to other passengers in the car as the dog protrudes from the security area. Inconvenience can also be prevented.

  In addition, by performing authentication at the time of getting in the car, it is possible to set different time zones for enabling the security area according to individual passengers, such as always for children and only at night for adults. In the second embodiment, image authentication is used as a passenger authentication unit for authenticating a specific passenger. However, the present invention is not limited to this, and an apparatus that can identify an individual such as an IC tag, voice, and fingerprint. I just need it.
