The frame rate may be any rate, such as 15 fps or 30 fps.

FIG. 5 is a diagram showing the configuration of the user DB stored in the storage unit 12 of the group supervisory control device 10. As shown in FIG.

The user DB records permitted floors and default destination floor array 1 to default destination floor array 5 in association with user face data. Registration of such information in the user DB is performed by, for example, an elevator manager or a building manager.

“Face data” is data used in face authentication of the user. The “face data” may be face image data (face image data) or face feature point data (face feature point data), as long as the face of the user can be distinguished. However, the case where the "face data" is face feature point data will be described below. Facial feature point data is, for example, data indicating the position and shape of the eyes, eyebrows, nose, mouth, etc., and features such as the outline of the face. The facial feature point data can be generated based on the facial photograph provided by the user for registration in the user DB or the facial image data of the user captured for registration.

The “permitted floor” is a floor that is permitted to be used by the user identified by the “face data”. Multiple floors can be designated as permitted floors.

"Default destination floor array 1" to "default destination floor array 5" are set for each departure floor (allowed floor), and each store a plurality of default destination floor values.

In the example shown in FIG. 5, "1, 12, 13, 14, 15" are set as allowed floors in association with face data 1, and "1, (12, 13, 14, 15" are set as default destination floor array 1. )” is set, “12, (1, 13, 14, 15)” is set as the default destination floor arrangement 2, and “13, (1, 12, 14, 15)” is set as the default destination floor arrangement 3 "14, (1, 12, 13, 15)" is set as the default destination floor arrangement 4, and "15, (1, 12, 13, 14)" is set as the default destination floor arrangement 5. The first 1 in "1, (12, 13, 14, 15)" of the default destination floor array 1 indicates that the departure floor is the first floor, and the parentheses ( ) indicate the first default floor ~ 4th default floor are listed in order, that is, the 1st default floor is the 12th floor, the 2nd default floor is the 13th floor, the 3rd default floor is the 14th floor, and the 4th default floor is the 15th floor. In addition, the first 12 in "12, (1, 13, 14, 15)" of the default destination floor array 2 indicates that it is an array when the departure floor is the 12th floor. , the first default floor to the fourth default floor are listed in order. That is, the first default floor is the first floor, the second default floor is the 13th floor, the third default floor is the 14th floor, and the fourth default floor is the 15th floor. Default destination floor arrangements 3-5 are also defined according to the same rules as default destination floor arrangements 1-2.

In the example shown in FIG. 5, "1, 12, 13, 14, 15" are set as allowed floors in association with face data 2, and "1, (15, 14, 13)" are set as default destination floor array 1. , 12)" is set, "12, (1, 15)" is set as the default destination floor arrangement 2, and "13, (1, 15)" is set as the default destination floor arrangement 3, and the default destination floor arrangement 4 is set to "14, (1, 15)", and the default destination floor arrangement 5 is set to "15, (1, 14, 13, 12)". The first 1 in "1, (15, 14, 13, 12) of the default destination floor array 1 indicates that the departure floor is the first floor, and the first default floor ~ 4th default floor are listed in order, that is, the 1st default floor is the 15th floor, the 2nd default floor is the 14th floor, the 3rd default floor is the 13th floor, and the 4th default floor is the 12th floor. In addition, the first 12 in "12, (1, 15)" of the default destination floor array 2 indicates that the departure floor is the 12th floor, and the first default The floor to the second default floor are listed in order. That is, it indicates that the first default floor is the first floor and the second default floor is the fifteenth floor. Note that the 3rd default floor and the 4th default floor are not registered at the request of the user. Default destination floor arrangements 3-5 are also defined according to the same rules as default destination floor arrangements 1-2.

Similarly, for the remaining face data, permitted floors and default destination floor array 1 to default destination floor array 5 are registered in association with the face data.

6A and 6B are diagrams showing the configuration of the re-registration DB stored in the storage unit of the group supervisory control device.

The re-registration DB contains data relating to calls currently assigned to elevators. Specifically, the re-registration DB associates the face data of the user who generated the call with the current assigned departure floor, assigned destination floor, assigned elevator, next destination floor, and registration of the call. recording the time. Registration of these pieces of information in the re-registration DB is performed by the group supervisory control device 10 .

"Face data" is data similar to the face data described in the user DB.

"Assigned Departure Floor" is the currently assigned departure floor.

"Assigned Destination Floor" is the currently assigned destination floor.

The “assigned car” is the currently assigned car (elevator).

The "next destination floor" is the destination floor that is set when the face corresponding to the face data is next detected.

"Registration time" is the registration time of the call. The call registration time is substantially the same time as the call origination time.

In the example shown in FIG. 6A, "1" is set as the assigned departure floor, "12" is set as the assigned destination floor, and "1" is set as the assigned car in association with face data 1. "13" is set as the destination floor, and "2021/04/14/15:30:10" is set as the registered time. Also, in association with face data 2, "13" is set as the allocated departure floor, "1" is set as the allocated destination floor, "2" is set as the allocated car, and "15" is set as the next destination floor. " is set, and "2021/04/14/15:30:12" is set as the registration time. Similarly, for the remaining face data, the current assigned departure floor, the assigned destination floor, the assigned car, the next destination floor, and the registration time of the call are registered in association with the face data.

FIG. 6B shows that for the user corresponding to face data 1, the face is detected again before a predetermined time has passed since the previous call registration, and as a result, the elevator is assigned to the next default destination floor, An example in which data related to face data 1 is updated is shown. Specifically, the assigned departure floor remains the 1st floor, but the assigned destination floor is updated to the 13th floor, the assigned elevator is updated to the 2nd elevator, and the next destination floor is updated to the 14th floor. Also, the registration time is updated to "2021/04/14/15:30:13". Here, the predetermined time is a time for judging whether or not the user has an intention to change and register a different default destination floor, and is, for example, 20 seconds.

2. Elevator System Operation The operation of the elevator system will now be described in more detail with reference to flowcharts.

FIG. 7 is a flow chart explaining the operation of the destination floor registration device 30. As shown in FIG.

The control unit 31 of the destination floor registration device 30 causes the display unit 34 to display an initial screen (S10).

FIG. 8 is a diagram showing an example of the initial screen. In the example of the initial screen in FIG. 8, a message "Please perform face authentication when using the elevator" is displayed.

Returning to FIG. 7, the control unit 31 of the destination floor registration device 30 determines whether or not the captured image output from the face authentication camera 35 includes a face (S11). Specifically, face detection processing is performed on the image data of the captured image.

When the face is not included in the captured image (NO in S11), that is, when the face is not detected, the controller 31 of the destination floor registration device 30 executes the process of step S11 again.

If the captured image includes a face (YES in S11), the control unit 31 of the destination floor registration device 30 generates an allocation request signal including the departure floor and face data and transmits it to the group supervisory control device 10 ( S12). The installation floor of the destination floor registration device 30 is used as the departure floor. The “face data” here may be face image data (face image data) or face feature point data (face feature point data), as long as the face of the user can be distinguished. However, in the following description, the “face data” is assumed to be face feature point data. Face data for transmission (facial feature point data) is acquired by analyzing the captured image when it is determined in step S11 that a face is included. By transmitting the facial feature point data to the group supervisory control device 10, the group supervisory control device 10 does not need the process of acquiring the facial feature point data from the image data of the captured image.

The control unit 31 of the destination floor registration device 30 determines whether or not an allocation result signal including the destination floor, the allocated car name, and the change flag has been received from the group supervisory control device 10 (S13).

When the allocation result signal is received (YES in S13), the control unit 31 of the destination floor registration device 30 determines whether or not the change flag is "True" (S14).

If the change flag is "True" (YES in S14), the control unit 31 of the destination floor registration device 30 causes the display unit 34 to display the allocation result guidance screen for a certain period of time (S15). The certain period of time is a period of time during which the user can appropriately recognize the display contents of the allocation result guidance screen, and is, for example, 3 seconds.

FIG. 9A is a diagram showing an example of an allocation result guide screen. In the allocation result guidance screen of FIG. 9A, the face image of the user whose face has been authenticated is displayed in the face image display area A1 on the right side, and information indicating the allocation result is displayed in the allocation result display area A2 on the left half. shows an example. As the face image, an image of an area obtained by extracting the detected face portion from the entire area of the captured image is displayed. Information on the destination floor and the assigned car is displayed as the information on the assignment result. FIG. 9A shows the case where the destination floor is the 12th floor and the assigned elevator is the 1st elevator. A message display area A3 is provided above the areas A1 and A2. The allocation result guide screen of FIG. 9A shows an example in which nothing is displayed in the message display area A3.

If the change flag is not "True" (NO in S14), that is, if it is "False", the control unit 31 of the destination floor registration device 30 causes the display unit 34 to display an allocation change guide screen for a certain period of time (S16). The certain period of time is a period of time during which the user can appropriately recognize the display content of the allocation change guidance screen, and is, for example, 3 seconds.

FIG. 9B is a diagram showing an example of an allocation change guide screen. The allocation change guidance screen has the same configuration as the allocation result guidance screen in FIG. 9A. On the assignment change guidance screen, a message indicating that the destination floor has been changed is displayed in the message display area A3. The assignment change guidance screen in FIG. 9B shows an example in which a message "Destination floor changed" is displayed.

In step S13, if the allocation result signal has not been received (NO in S13), the control section 31 of the destination floor registration device 30 determines whether or not an error signal has been received from the group supervisory control device 10 (S17). .

If no error signal has been received (NO in S17), the control unit 31 of the destination floor registration device 30 returns to the determination in step S13.

When an error signal is received (YES in S17), the control unit 31 of the destination floor registration device 30 causes the display unit 34 to display an error screen (S18). The error screen is a screen for notifying that an elevator cannot be assigned to a user who has undergone face authentication. The certain period of time is a period of time during which the user can appropriately recognize the display content of the error screen, and is, for example, 3 seconds.

FIG. 10 is a diagram showing an example of an error screen. In the example of the error screen in FIG. 10, it is displayed as "You cannot use the elevator."

FIG. 11 is a flow chart explaining the operation of the group supervisory control device 10. As shown in FIG. Processing based on this flowchart is executed for each destination floor registration device 30 . That is, each destination floor registration device 30 is processed in parallel.

The control unit 11 of the group supervisory control device 10 determines whether or not an allocation request signal has been received from the destination floor registration device 30 (S31).

If the allocation request signal has not been received from the destination floor registration device 30 (NO in S31), the control unit 11 of the group supervisory control device 10 executes the determination of step S31 again.

When an allocation request signal is received from the destination floor registration device 30 (YES in S31), the control unit 11 of the group supervisory control device 10 uses face data that matches the face data included in the received allocation request signal to a certain extent or more. It is determined whether or not the person is registered in the person DB (S32). That is, face authentication is performed on the face associated with the face data included in the allocation request signal. Various known methods can be used to compare face data for this determination. For example, the face data (facial feature point data) included in the allocation request signal and each face data (facial feature point data) registered in the user DB are sequentially compared (verified) to obtain the matching rate. Then, it is determined whether face data having a matching rate equal to or higher than a predetermined matching rate with respect to the face data included in the allocation request signal is registered in the user DB. When face data having a matching rate equal to or higher than a predetermined matching rate is registered in the user DB, the control unit 11 of the group supervisory control device 10 controls the use of the face data (facial feature point data) included in the allocation request signal. It determines that the person (the user whose face has been detected) is a user registered in the user DB, and determines that face authentication has succeeded.

If face data that matches the received face data to a certain degree or more is not registered in the user DB (NO in S32), the control unit 11 of the group supervisory control device 10 outputs an error signal to the destination of the transmission source of the allocation request signal. It is transmitted to the floor registration device 30 (S41), and the process returns to step S31. The destination floor registration device 30 that is the transmission source of the allocation request signal can be appropriately specified by including the device ID of the destination floor registration device 30 in the allocation request signal.

If face data that matches the received face data to a certain degree or more is registered in the user DB (YES in S32), the control unit 11 of the group management control device 10 retrieves the registered face data from the user DB. acquires various data associated with (S33).

The control unit 11 of the group supervisory control device 10 determines whether or not face data matching the face data included in the received allocation request signal to a certain extent or more is registered in the re-registration DB (S34). This determination can be made in the same manner as the determination in step S32.

If the face data matching more than a certain degree is not registered in the re-registration DB (NO in S34), the control unit 11 of the group supervisory control device 10 sets the change flag to "False" (S35).

The control unit 11 of the group supervisory control device 10 sets the destination floor dest (S36).

FIG. 12 is a flowchart for explaining the process of setting the destination floor dest.

The control unit 11 of the group supervisory control device 10 acquires the default destination floor arrangement corresponding to the departure floor from the user DB (S51).

The control unit 11 of the group supervisory control device 10 sets the top floor of the acquired default destination floor array as the destination floor dest (S52).

For example, assuming that the face data matching the face data included in the received allocation request signal to a certain degree or more is face data 1 in the user DB in FIG. In S51, the default destination floor array 1 is obtained. When the departure floor is the 1st floor, the plurality of default destination floors are (12, 13, 14, 15), and in step S52, the top floor "12" of these default destination floors is set as the destination floor dest. .

After completing the processing of step S52, the control unit 11 of the group supervisory control device 10 returns to the processing of the flowchart of FIG. 11, and determines the assigned car for the departure floor and the set destination floor dest included in the assignment request signal. (S37). A well-known technique or the like may be used to determine the optimum number of elevators to be assigned from among a plurality of elevators (numbers).

The control unit 11 of the group supervisory control device 10 sets the next destination floor nextdest (S38).

FIG. 13 is a flowchart for explaining the process of setting the next destination floor nextdest.

The control unit 11 of the group supervisory control device 10 acquires the default destination floor arrangement corresponding to the departure floor from the user DB (S71).

The control unit 11 of the group supervisory control device 10 sets the destination floor located next to the set destination floor dest as the next destination floor nextdest in the acquired default destination floor array (S72).

For example, assuming that the face data matching the face data included in the received allocation request signal to a certain degree or more is face data 1 in the user DB in FIG. In S71, the default destination floor array 1 is obtained. If the departure floor is the 1st floor, the default destination floor is (12, 13, 14, 15), and if the currently set destination floor dest is, for example, the 13th floor, the next destination floor nextdest is the 14th floor. Become. If the currently set destination floor dest is, for example, the 15th floor, the next destination floor nextdest will be the 12th floor.

After completing the processing of step S72, the control unit 11 of the group supervisory control device 10 returns to the processing of the flowchart of FIG. Assigned departure floor and destination floor dest, assigned car, set next destination floor nextdest, and assigned car decision time are stored in the re-registration DB as face data, assigned departure floor, and assigned destination. The floor, assigned car, next destination floor, and registration time are registered (S39).

The control unit 11 of the group supervisory control device 10 transmits an allocation result signal including the destination floor dest, the allocated car name, and the change flag to the destination floor registration device 30 that transmitted the allocation request signal (S40).

In step S34, if face data that matches a certain degree or more is registered in the re-registration DB (YES in S34), the control unit 11 of the group supervisory control device 10 retrieves the face data that matches the certain degree or more from the re-registration DB. Data associated with face data is acquired (S42). The data acquired here includes at least the data of the allocated departure floor, the allocated destination floor, and the allocated car number.

The control unit 11 of the group supervisory control device 10 transmits a call cancel signal to the elevator control device 40 of the assigned car acquired in step S42 (S43). The call cancel signal is a signal for instructing cancellation of the call regarding the assigned departure floor and the assigned destination floor acquired in step S42. Upon receiving the call cancellation signal, the elevator control device 40 cancels the allocation of the allocated departure floor and the allocated destination floor included in the call cancellation signal to the corresponding elevators 60 .

The control unit 11 of the group supervisory control device 10 deletes data (records) related to face data that matches more than a certain degree from the re-registration DB (S44).

The control unit 11 of the group supervisory control device 10 sets the change flag to "True" (S45).

The control unit 11 of the group supervisory control device 10 sets the next destination floor nextdest acquired in step S42 as the destination floor dest (S46), and executes the processes after step S37 described above.

3. Actions/Effects, etc. Actions/effects, etc. of the present embodiment will be described. When using the elevator of this embodiment, the user first goes in front of the destination floor registration device 30 . The destination floor registration device 30 repeatedly performs face detection processing on the captured image captured by the face authentication camera 35 at regular time intervals. information on the floor where the destination floor registration device 30 is installed) and an allocation request signal including the generated face data is transmitted to the group supervisory control device 10 . The group supervisory control device 10 determines whether or not face data matching the face data included in the received allocation request signal to a certain degree or more is registered in the user DB. Various data linked to the face data are acquired from the user DB. Further, it is determined whether or not face data matching the face data included in the received allocation request signal to a certain degree or more is registered in the re-registration DB, and depending on the determination result, the following (1) or (2) is performed. ) is processed.

(1) When facial data that matches more than a certain degree is not registered in the re-registration DB Face data that matches more than a certain degree is registered in the user DB, but not registered in the re-registration DB means that the user has not used the destination floor registration device 30 for a predetermined time (for example, 20 seconds as described above). To give a specific example, when the building is an office building, it is assumed that the user uses the destination floor registration device for the first time at the time of going to work or leaving work. In such a case, the group supervisory control device 10 acquires the default destination floor array corresponding to the departure floor from the user DB, sets the top floor of the acquired default destination floor array as the destination floor dest, and requests allocation. The allocated car is determined for the departure floor and the set destination floor dest included in the signal. The group supervisory control device 10 transmits an allocation result signal including the destination floor dest and the allocated car name to the destination floor registration device 30 which is the transmission source of the allocation request signal. When the destination floor registration device 30 receives the allocation result signal from the group control device 10, the allocation result guide screen including the destination floor dest, the allocated car name, and the face image is displayed on the display unit 34 as shown in FIG. 9A. indicate. This allows the user to recognize his/her own destination floor and assigned car name.

(2) When face data that matches more than a certain degree is registered in the re-registration DB It means that the same or another destination floor registration device 30 on the same floor was used again within a predetermined time (for example, 20 seconds as described above) after using the destination floor registration device 30 . In other words, according to the above example, it is assumed that the user uses the destination floor registration device for the second time, for example, within a predetermined period of time when he or she leaves work. To give a specific example, when the user continues to stand in front of the destination floor registration device 30 after being assigned an elevator for the first default destination floor in order to be assigned another default destination floor. is assumed. Alternatively, after receiving an elevator assignment for the first default destination floor, within a predetermined time (for example, 20 seconds as described above) in order to receive an assignment for another default destination floor, the same or other destination floor of the same floor It is assumed that the user returns to the registration device 30 and re-assigns the elevator. In such a case, the group supervisory control device 10 acquires from the re-registration DB the data linked to the face data that matches more than a certain degree, and sets the next destination acquired from the re-registration DB as the destination floor dest. Set rank nextdest. Then, the allocated car is determined for the departure floor and the set destination floor dest included in the allocation request signal. The group supervisory control device 10 transmits an allocation result signal including the destination floor dest and the allocated car name to the destination floor registration device 30 which is the transmission source of the allocation request signal. When the destination floor registration device 30 receives the allocation result signal from the group supervisory control device 10, the destination floor registration device 30 displays on the display unit 34 an allocation including the destination floor, the assigned car name, the destination floor change message, and the face image, as shown in FIG. 9B described above. Display the change guidance screen. As a result, the user can receive an elevator assignment for another default destination floor and recognize the changed destination floor and assigned elevator name without performing any special operation. In addition, the group supervisory control device 10 deletes the data linked to the face data that matches more than a certain degree from the re-registration DB, and transmits a call cancel signal to the elevator control device 40 of the assigned car. As a result, it is possible to prevent the allocated calls from remaining as useless calls.

Further, in the present embodiment, by registering a plurality of default destination floor arrangements for each departure floor in the user DB, different default destination floors can be set for each departure floor. Users often request different destination floors depending on the departure floor, and this can be handled appropriately.

In the present embodiment, each of the plurality of default destination floors is assigned a priority order, and the priority order is set according to the user's request. As a result, each time the user's face is detected, different default destination floors are assigned in the order desired by the user. Therefore, in the case of adopting a configuration in which a different destination floor is set each time a face is detected, the convenience of destination floor registration can be improved. For example, the default destination floor array 1 linked to face data 1 in the user DB of FIG. Destination floors are assigned in the order of the 12th, 13th, 14th, and 15th floors, that is, in ascending order. On the other hand, the default destination floor array 1 linked to the face data 2 is an array when the departure floor is the first floor. , 14th floor, 13th floor, and 12th floor, that is, in descending order.

In addition, the default destination floor arrays 1 to 5 attached to face data 1 in the user DB of FIG. Destination floor arrays 2 to 4 include only two floors, the 1st floor and the 15th floor, as destination floors. In this embodiment, such setting is allowed according to the user's request. By reducing the number, it is possible to easily receive an assignment to the target destination floor with a small number of face detections.

Here, conventionally, there is a system in which a user can register a default destination floor by holding an ID card or the like over a card reader. However, if the passenger wants to go to a floor other than the default destination floor, it is necessary to register the destination floor using the destination floor registration device 30 equipped with a numeric keypad, etc., which poses a problem in terms of convenience. However, according to the destination floor registration device 30 of the present embodiment, it is possible to register an arbitrary destination floor among a plurality of default destination floors by face authentication with one destination floor registration device 30 . Therefore, the convenience of destination floor registration can be improved. In addition, since there is no need to perform touch operations on the numeric keypad or the like, it is possible to suppress infections caused by viruses, bacteria, and the like.

(Other embodiments)

In the above embodiment, the user DB is stored in the storage unit 12 of the group control device 10, but depending on the building, a security system using face authentication may be provided. Such a security system usually has a database that stores face data for face authentication and the like. Therefore, the data of the default destination floor may be registered in association with the face data of this database, and the group supervisory control device 10 may acquire the data of the default destination floor from this database.

In the above-described embodiment, the destination floor registration device 30 is arranged on the elevator hall of each floor or on the wall surface of the building in the vicinity thereof. A registration device 30 may be arranged. In this case, the opening and closing of the flapper of the security gate may be controlled based on the face recognition result in the group supervisory control device 10 .

In the above embodiment, the case where "face data" is face feature point data has been described. However, the invention is not so limited. The “face data” may be face image data. The format of the image data may be any format such as bmp format, jpg format, gif format, or the like. When "face data" is used as image data, face image data may be registered as "face data" in the user DB. In step S12 of FIG. 7, the destination floor registration device 30 transmits an allocation request signal including face image data as "face data" to the group supervisory control device 10. FIG. The image data of the face is acquired from the captured image, for example, when it is determined that the face is included in step S11. Upon receiving the allocation request signal, the group supervisory control device 10 determines whether or not face data matching the face data included in the allocation request signal to a certain extent or more is registered in the user DB (re-registration DB) ( S32 (S34)). For example, the face data (face image data) included in the allocation request signal and each face data (face image data) registered in the user DB are sequentially compared (verified) to obtain the match rate. Then, it is determined whether face data having a matching rate equal to or higher than a predetermined matching rate with respect to the face data included in the allocation request signal is registered in the user DB (re-registration DB). When face data having a matching rate equal to or higher than a predetermined matching rate is registered in the user DB (re-registration DB), the control unit 11 of the group supervisory control device 10 retrieves the face data (face image data) included in the allocation request signal. ) (the user whose face has been detected) is a user registered in the user DB (re-registration DB).

Although the elevator system having a plurality of elevators 60 was illustrated in the above embodiment, the present invention is also applicable to an elevator system having a single elevator.
