  The flow of processing in the elevator control device 1 will be described with reference to the flowchart of FIG. In the following flowchart, it is assumed that the elevator has arrived at the elevator platform 30.

When the elevator arrives and the elevator is opened, the imaging unit 46 of the car operation panel 41 provided on the side surface of the elevator car 4 automatically starts imaging. The video from the imaging unit 46 is transmitted from the car control device 5 to the recognition unit 13 of the elevator control device 1, and the recognition unit 13 converts the video into a still image, and detects a face image if there is a human face in the still image. (S11). If no human face image is detected (NO in S11), the process of step S11 is repeated until the elevator is closed and the car leaves (NO in S20), and ends when the car leaves (S20). YES). On the other hand, when a human face image is detected (YES in S11), the collation unit 11 collates the detected face image with image data 18 registered in advance in the storage unit 14.

If the face image matches the image data 18, and if the departure floor of the database 17 associated with the matched image data 18 matches the user's boarding floor (YES in S12), the database 17 matches. Records are extracted (S13). On the other hand, when the face image does not match all the image data 18, or even when the face image matches the image data 18, the departure floor of the database 17 and the boarding floor of the user associated with the matched image data 18 are different. If they do not match (NO in S12), the processing from step 11 is repeated.

Next, the destination floor is selected from the record extracted according to the traveling direction of the car. If the car traveling direction is upward (YES in S14), there is a destination floor that is higher than the departure floor of the extracted record (YES in S15), or the traveling direction of the car is not upward in step S14 ( In other words, when there is a destination floor that is below the departure floor of the extracted record (NO in S14, YES in S16), the destination floor is registered as a wheelchair specification (S17).

Thereafter, the same destination floor as the destination floor automatically registered from among the destination floors of the registration unit of the car operation panel 41 is turned on (S18). Then, the user is informed by voice or text that the destination floor has been registered (S19). After step S19, or when the record extracted in step S15 does not have a destination floor above the departure floor (NO in S15), or the record extracted in step S16 does not have a destination floor below the departure floor (NO in S16), the process from step 11 is repeated.

In step S18, any one of 42 (1) to (5) in FIG. 3 is lit according to the destination floor that is automatically registered. Here, the destination floor automatically registered may be lit in a different color from the destination floor registered with the user. For example, when the user registers the destination floor by operating the registration unit 42 of the car operation panel on the side of the car, the destination floor automatically registered is red.

In addition, the destination floor door registered by the user on the car operation panel on the side of the car is normally controlled, and the destination floor door registered automatically is specially controlled (the door is open longer than the normal control). ) May be performed.

Moreover, when the car operation panel is installed on both the left side and the right side of the car, it is possible to detect the face image of the elevator wheelchair user by the respective imaging units.

FIG. 5 is an example of the database 17 stored in the storage unit 14 and is a wheelchair user.

“Name”, “Face 1”, “Face 2”, “Face 3”, “Face 4”, “Face 5”, “Departure Floor”, “Destination Floor”, “Description” are described as the header of the database 17. ing.

“Name” is a name. “Face 1” to “Face 5” are personal face information (such as JPEG files) and are stored in the image data 18 of FIG. For example, “face 1” is a front face, “face 2” is a right diagonal face, “face 3” is a right face, “face 4” is a left diagonal face, and “face 5” is a left face. The departure floor is the user's boarding floor, the destination floor is the user's destination floor, and the description describes the purpose of moving from the departure floor to the destination floor.

The first person name “A” registers “A1” to “A5” as face information in the image data 18 of FIG. Four combinations of departure floor and destination floor are registered. The first is the movement from the departure floor “1” to the destination floor “2” and “lobby floor to office”. The second is the movement from the departure floor “2” to the destination floor “1” and from the “office room to the lobby floor”. The third is the movement from the departure floor “2” to the destination floor “5” and from the “office room to the conference room”. The fourth is the movement from the departure floor “5” to the destination floor “2” and “conference room to office”.

The name “B” of the second person registers “B1” to “B5” as face information in the image data 18 of FIG. Four combinations of departure floor and destination floor are registered. The first is the movement from the departure floor “1” to the destination floor “3” and “lobby floor to office”. The second is the movement from the departure floor “3” to the destination floor “1” and from the “office room to the lobby floor”. The third is the movement from the departure floor “3” to the destination floor “5” and from the “office to the conference room”. The fourth is the movement from the departure floor “5” to the destination floor “3” and “conference room to office”.

The third person's name “C” registers “C1” to “C5” as face information in the image data 18 of FIG. Four combinations of departure floor and destination floor are registered. The first is the movement from the departure floor “1” to the destination floor “4” and from the lobby floor to the office. The second is the movement from the departure floor “4” to the destination floor “1” and from the office to the lobby floor. The third case is the movement from the departure floor “4” to the destination floor “5” and from the office to the conference room. The fourth case is the movement from the departure floor “5” to the destination floor “4” and “conference room to office”.

As described above, “A”, “B”, and “C” are “1” having the same departure floor, but “2”, “3”, and “4” are different on the destination floor for each individual. “A” is “2” when the departure floor is “2”, the destination floor is “1” if the direction of arrival of the car is down, and the destination floor is “1” if the direction of arrival of the car is upward. 5 ". Similarly, when the departure floor is “3”, “B” indicates that the destination floor is “1” if the traveling direction of the arriving car is downward, and the destination floor is “1” if the traveling direction of the arriving car is upward. “C” indicates that the departure floor is “4”, and the destination floor is “1” if the direction of arrival of the car is downward, the direction of arrival of the car is upward. If there is, the destination floor is “5”.

Here, a specific example of the present invention will be described on the basis of the flowchart in FIG. 4 and the case where “A” in FIG.
First, “A” that has been on the elevator in step S11 is imaged by the imaging unit of the car operation panel on the side of the car, the video signal is converted into a still image by the recognition unit, and the detection unit detects “A” from the still image. An image was detected.

In step S12, the face image “A” is collated with the image data 18 registered in the storage unit 14. Here, the face image of “A” and A2. Assume that they match in the collation with JPEG. In this case, the first condition is that “A2” is included in the face 2 of the database 17. Next, since “A” is on board from the second floor, the second condition is that “2” is included in the departure floor of the database 17. Two records satisfy the first condition and the second condition.

Therefore, in step S13, a record whose destination floor is “1” and a record whose destination floor is “5” are extracted.

Next, in step S14, since "A" has boarded the car whose traveling direction is upward from the second floor, the process proceeds to step S15. Since the record extracted in step S13 includes a record whose fifth floor is higher than the second floor of the boarding floor, the fifth floor is registered as a wheelchair specification car call in step S17. In step S18, the fifth floor of the registration section of the car operation panel is turned on, and in step S19, the user is informed by voice or display that the fifth floor has been registered.

  As described above, by providing an imaging unit on the car operation panel on the side of the elevator car, it is easier to recognize the wheelchair user's face image, and elevator control that enables automatic registration of the destination floor Equipment can be provided. Therefore, the wheelchair user can go to the destination floor only by getting in the car without operating the car operation panel.
