The elevator control unit 10 receives information from the elevator guide area 1 and the elevator hall 2 and controls the operation of the elevator such as opening and closing the door of the elevator car and controlling the traveling of the elevator car.

The first acquisition information storage unit 11 stores the image information acquired by the first camera 3, and the user information storage unit 12 stores the user information of the user registered in advance. This user information includes a face image that is the user's specific information and attribute information associated with the face image.

The first recognition unit 13 recognizes the face image of the user who called the elevator by the car calling unit 4 included in the image information stored in the first acquired information storage unit 11 and is stored in the user information storage unit 12 in advance. The user information storage unit 12 is searched for a face image that matches the face recognition image of the user in the elevator guide area 1 by referring to the stored face image, and if stored, the matched face image The attribute information corresponding to is fetched. Thereby, the attributes of the user in the elevator guide area 1 are recognized.

The car attribute storage unit 15 stores the car attributes that are assigned to each elevator car in advance. The car attribute corresponds to the attribute of the user who uses the car, and is, for example, an attribute indicating that the car is a car with priority for the elderly or a car with priority for people with disabilities.

The deciding unit 14 refers to the car attributes stored in the car attribute storage unit 15, and sets an attribute that matches the attribute of the user who called the elevator by the car calling means 4 recognized by the first recognition unit 13. The elevator is determined from the plurality of elevators.

According to the decision of the decision unit 14, the guidance control unit 16 controls the guidance display unit 5 to display to the user who called the elevator by the car calling means 4 which car is assigned.

The second acquisition information storage unit 17 stores the image information acquired by the second camera 6. The second recognition unit 18 recognizes the face image of the user at the elevator hall 2 included in the image information stored in the second acquired information storage unit 17, and the face image stored in advance in the user information storage unit 12. The user information storage unit 12 is searched for a face image that matches the face recognition image of the user in the elevator hall 2, and if stored, the attribute information corresponding to the matched face image is searched. Take in. As a result, the attributes of the user at the elevator hall 2 are recognized.

The determination unit 19 determines whether the attributes of the user at the elevator hall 2 recognized by the second recognition unit 18 and the attributes of the car at the hall stored in the car attribute storage unit 15 match.

The notification unit 20 receives the determination result of the determination unit 19, and when the attributes of the user at the elevator hall 2 and the attributes of the car at the hall do not match, the notification unit 20 controls the notification device 7 at the elevator hall 2 to cause the wrong number of units. Or the information such as the number of an appropriate machine is notified.

In such an elevator control device 9, the first recognition unit 13, the determination unit 14, the guidance control unit 16, the second recognition unit 18, the determination unit 19, and the notification unit 20 detect the user of the elevator according to the present invention. The device 21 is configured.

The first acquisition information storage unit 11 and the second acquisition information storage unit 17 may be configured by the same storage device. Further, the first recognizing unit 13 and the second recognizing unit 18 perform the same operation, and therefore may be configured in common.

Next, an operation of the elevator according to the first embodiment, particularly an operation of detecting a user attribute and assigning a car suitable for each user will be described.

First, the operation when the user uses the car calling means 4 in the elevator guide area 1 will be described. FIG. 3 is a flowchart showing the control operation of the elevator control device 9 when the user uses the car calling means 4 in the elevator guide area 1.

When the elevator starts operation, the elevator control unit 10 starts controlling the operation of the car. During operation of the car, the elevator controller 10 monitors the operation of the car calling means 4 in step S1. When an operation is performed on the car calling means 4, operation information corresponding to the operation is sent from the car calling means 4 to the elevator control section 10 via the communication section 8a, the network 8 and the communication section 8b so that the elevator can be operated. Used. At the same time, when the car calling means 4 is operated, the user who has operated the first camera 3 is photographed, and the photographed image information is transmitted via the communication unit 8a, the network 8, and the communication unit 8b. It is sent to and stored in the first acquisition information storage unit 11.

Then, in step S2, the first recognition unit 13 recognizes the person included in the image information stored in the first acquired information storage unit 11, that is, the face image of the user who called the elevator by the car calling unit 4 and A reference is made to a face image stored in the user information storage unit 12 in advance to find out whether a face image that matches the recognized face image of the user is stored in the user information storage unit 12.

When a matching face image is found in step S2, the process proceeds to step S3. In step S3, the first recognition unit 13 recognizes the attribute of the user in the elevator guide area 1 by loading the attribute information corresponding to the matched face image from the user information storage unit 12.

If no matching face image is found in step S2, the process proceeds to step S4, and the attribute of the user is recognized as "none".

After step S3 or step S4, the process proceeds to step S5, in which the determination unit 14 refers to the user attribute recognized by the first recognition unit 13 and the car attribute stored in the car attribute storage unit 15, Elevators having attributes set to those of No. A to D are determined from the elevators of the A to D vehicles. When the user's attribute is "none", the elevators set to allocate the user having the attribute "none" are determined from the elevators of the A to D machines.

When determining an elevator car having a car attribute that matches the attribute of the user in the elevator guide area 1, if there is no car having the same car attribute as the user's attribute, the attribute contents are similar. For example, if the user is an elderly person and there is a car with an attribute for the handicapped person that does not have an attribute for the elderly person, a common attribute for people with disabilities, which is a common attribute that assumes a long boarding time Determine the car as a car that fits older users. Furthermore, if there is no car with a similar attribute, one of the cars is set to the same attribute as the user attribute or changed to determine. In that case, the car attribute stored in the car attribute storage unit 15 is rewritten to the car attribute determined by the determination unit 14.

After step S5, the process proceeds to step S6, and the guidance control unit 16 follows the decision of the decision unit 14 and displays a guidance to the user who called the elevator by the car calling means 4 so as to display which car is assigned. The part 5 is controlled. As a result, guidance indicating the elevator number suitable for the user is displayed on the guidance display unit 5, and the user moves to the vicinity of the elevator hall 2 of the elevator number designated according to this guidance.

Next, the operation of detecting the user at the elevator hall 2 will be described. FIG. 4 is a flowchart showing the control operation performed by the elevator control device 9 when detecting the user at the elevator hall 2.

While driving the car, the second camera 6 always photographs the elevator hall 2 of each of the vehicles A to D. The captured image information is sent to and stored in the second acquired information storage unit 17 via the communication unit 8c, the network 8 and the communication unit 8b.

Then, in step S<b>7, the second recognition unit 18 monitors the image information of the elevator hall 2 stored by the second acquired information storage unit 17 for a person, that is, a user waiting for the elevator at the elevator hall 2. If it is recognized that there is a user, the process proceeds to step S8.

In step S8, the second recognition unit 18 recognizes the person included in the image information stored in the second acquired information storage unit 17, that is, the face image of the user who called the elevator by the car calling unit 4 and uses the same. By referring to the face image stored in advance in the user information storage unit 12, it is searched whether a face image that matches the recognized face image of the user is stored in the user information storage unit 12.

If a matching face image is found in step S8, the process proceeds to step S9. In step S9, the second recognition unit 18 recognizes the attribute of the user at the elevator hall 2 by loading the attribute information corresponding to the matched face image from the user information storage unit 12.

If no matching face image is found in step S8, the process proceeds to step S10 and the attribute of the user is recognized as "none".

After step S9 or step S10, the process proceeds to step S11, in which the determination unit 19 refers to the car attributes stored in the car attribute storage unit 15, and determines the user attributes recognized in step S9 or step S10 and this user. It is determined whether or not the car attributes set in the car of the elevator hall 2 that has been photographed match, and the notification unit 20 notifies the result determined by the determination unit 19 in step S8 as the determination result information. This determination result information indicates whether or not the user at the elevator hall 2 is about to get into the car suitable for the attribute of the user, and thus can be used for the guidance display to the user according to the determination result. At the same time, it can be used for elevator operation according to the determination result. Therefore, the notification destination of the determination result information is the elevator control unit 10, the communication unit 8c of the elevator landing 2 for guidance at the elevator landing 2, and the elevator control unit 10 for reflecting the operation of the elevator. Good.

As described above, it is determined whether the attributes of the user at the elevator hall 2 and the attributes of the car corresponding to the elevator hall 2 match, and the determination result information is appropriately notified to each part of the elevator.

When the elevator control unit 10 is notified of this determination result information, the elevator control unit 10 can reflect the determination result in the operation of the elevator. For example, if the attributes of the user and the car match, it means that the user is trying to get on a car that is suitable for his/her own attribute, and the elevator that has received the determination result that the attributes of the user and the car match. When the control unit 10 operates the car and arrives at the elevator hall 2 on the floor where the user is, the control unit 10 opens the door as usual so that the user can get into the car. On the other hand, if the attributes of the user and the car do not match, it means that the user is trying to get on the car that is suitable for his/her own attribute, and the result of the determination that the attributes of the user and the car do not match indicates that The notification device 7 of the elevator hall 2 that has received the instruction information is included by including the instruction information for controlling the notification device 7 of the hall 2 to indicate that the number is the wrong number or the information of the appropriate number. Alternatively, the elevator control unit 10 can notify the user of information such as an incorrect car number or an appropriate car number. Further, by including the instruction information for controlling the elevator car to be kept in the door closed state until the determination result that the attributes of the user and the car match, the elevator that receives this instruction information The control unit 10 can keep the elevator car in the door-closed state until the user arrives. As a result, it is possible to prevent a user in the elevator hall 2 whose attributes do not match from getting on an elevator whose attributes do not match. Further, as the control of the car by the elevator control unit 10, for example, in a car in which an attribute suitable for a person with a disability is set, the door is opened longer than usual, and in a car in which an attribute suitable for the elderly is set, an announcement of an arrival floor is made. It is possible to make the volume louder than usual and slow down the announcement speed.

Further, even if the determination result information from the notification unit 20 is directly notified to the elevator hall 2, the determination result can be used for the guidance display to the user. When the elevator hall 2 is provided with means for controlling the notification to the user by the notification device 7 by receiving the determination result information from the notification unit 20, and when the determination result that the attributes of the user and the car do not match is received. It is possible to inform the user that the number is the wrong number or the number of the appropriate number.

When there are a plurality of users in the elevator hall 2 and a user whose attributes are determined to match by the determination unit 19 and a user who is determined to not match the attributes are present at the same time, the priority is given to the matching determination. Is performed by the elevator control unit 10. Accordingly, for example, when a car assigned to a person with a disability priority is accompanied by an assistant for a person with a disability, the assistant can also use the car suitable for the person with a disability.

The operation when the user uses the car calling means 4 in the elevator guide area 1 and the operation of detecting the user at the elevator hall 2 are repeated in parallel during the operation of the elevator.

Further, in the present embodiment, when the face image of the user is not stored in the user information storage unit 12, the attribute of the user is recognized as “none” in step S4 and step S10. 13. The second recognition unit 18 analyzes the image information of the first acquisition information storage unit 11 or the second acquisition information storage unit 17 to extract the characteristics of the user in the image as the characteristic information, and the extracted characteristic information. May be recognized as an attribute of an unregistered user. In this way, when the first recognizing unit 13 and the second recognizing unit 18 are provided with the function of analyzing image information, the same effect as that of the above embodiment can be obtained without using the user information storage unit 12. Can play.

Further, in the present embodiment, the first recognition unit 13 and the second recognition unit 18 recognize the user by the face image, but as another method, the user may be recognized by the retina, iris, walking, or the like. Good.

In addition, in the present embodiment, when the user is a user registered in advance in the user information storage unit 12 when the user is detected in the elevator guide area 1, the user identification information is It was not used in the detection operation of the user at the hall 2, and the attributes of the user were uniquely recognized at the elevator hall 2. However, when the user identification information is obtained when the user is detected in the elevator guide area 1, and when this is used when the user attributes are recognized in the elevator hall 2, a more flexible elevator service can be provided. For example, the information of the assigned car determined by the determination unit 14 in step S5 during the operation when detecting the user of the elevator guidance area 1 is added to the corresponding user information of the user information storage unit 12 and stored. Then, when it is determined whether or not the user recognized by the second recognition unit 18 and the assigned car match in step S11 during operation when detecting the user of the elevator hall 2 thereafter, use By referring to the person information storage unit 12, the second recognition unit 18 can recognize the user coming to the elevator hall 2. In this way, if the specific user who is scheduled to come to the elevator hall 2 is known, the notification unit 20 notifies the specific user of information for the specific user, or the car is not moved until the target user comes. It is possible to perform a car operation service such as keeping the car waiting.

Further, the first camera 3 and the second camera 6 are provided as means for acquiring the information of the user, and the image information of the user is acquired. Instead, the first card reader and the second card reader are used. The personal identification card information of the user and the attribute of the user are stored in the user information storage unit 12 in association with each other, and the first recognition unit 13 is installed in the elevator guide area 1. In the case where the personal identification information of the user who called the elevator by the car calling means 4 received by the card reader of FIG. 1 is received and the personal identification information that matches the received personal identification information is stored in the user information storage unit 12 , The attribute stored in the user information storage unit 12 in correspondence with the matched personal identification information is recognized as the user attribute, and the second recognition unit 18 sets the elevator hall 2 in which the attribute of the boarding user is set. When the personal identification information of the user read by the second card reader installed in the personal computer is received, and the personal identification information that matches the received personal identification information is stored in the user information storage unit 12, it matches. The attribute stored in the user information storage unit 12 corresponding to the personal identification card information may be recognized as the attribute of the user.

According to the first embodiment as described above, not only is the attribute of the user recognized in the elevator guide area 1 and guidance is displayed to the car that performs driving suitable for the attribute, the attribute of the user is also displayed in the elevator hall 2. It recognizes that the user is in the proper car landing, so by preventing wrong boarding into an elevator car that is different from the assigned car, and by having the user use the appropriate car according to the user's attributes, We can provide adaptive and flexible elevator services.
