EXAMPLE 1

Elevator system

Fig. 1 is a block diagram showing a schematic configuration of an elevator system 10 according to embodiment 1 of the present invention. Hereinafter, the structure of the elevator system 10 according to embodiment 1 will be described with reference to other drawings as necessary based on fig. 1.

An elevator system 10 shown in the figure is a system for managing the operation of an elevator apparatus using a personal authentication technique, and includes a registration terminal 1, an input/output control system 2, a safety system 3, an elevator apparatus 4, a group management control system 7, and a door control unit 8. Hereinafter, each of these components will be described in detail in order. Here, the elevator apparatus 4 will be described as including a plurality of elevator cars 41a to 41 n.

< registration terminal 1>

The registration terminal 1 is a terminal device for registering a destination floor of an elevator user and performing personal authentication of the user. Fig. 2 is a diagram illustrating the installation position of the registration terminal in the elevator system 10 according to embodiment 1. Referring to fig. 2, the registration terminal 1 is provided on a side of a landing door 401 of an elevator landing 400. When the elevator apparatus 4 includes a plurality of elevator cars 41a to 41n and a plurality of landing doors 401 are present in the elevator landing 400, the registration terminals 1 may be provided on the sides of the landing doors 401, or one landing 400 may be provided.

This registration terminal 1 includes an information reading unit 1a, a destination floor registration unit 1b, a notification unit 1c, and an imaging unit 1 d. They do not need to be collected in one registration terminal 1, may be provided separately, and may take various configurations. The constituent elements thereof will be described below.

[ information reading section 1a and destination floor registration section 1b ]

The information reading unit 1a acquires information on the destination floor input by the user from the destination floor registration unit 1b, and registers the destination floor input by the user U (see fig. 2). The destination floor registration unit 1b is, for example, a numeric keypad type member, and a user U inputs a destination floor. The destination floor registered by the operation of the destination floor registration unit 1b is read by the information reading unit 1a and transmitted to the group management control system 7.

Such an information reading section 1a and a destination floor registration section 1b constitute a destination floor registration device. That is, in the elevator system 10, registration of the destination floor of the user U is completed by personal authentication of the user U imaged by the imaging unit 1d described below. However, the user U may register a destination floor for a floor different from a destination floor by personal authentication by operating the destination floor registration unit 1 b. The information reading unit 1a may have a function of reading identification information (hereinafter, referred to as user ID) of the user U from the information storage medium 100 held by the user U.

[ Notification section 1c ]

The notification unit 1c notifies the elevator number information indicating any one of the elevator number ladders 41a to 41n assigned to the user U in accordance with an instruction from the group management control system 7 described below. The notification unit 1c performs notification by, for example, display.

[ imaging section 1d ]

The imaging unit 1d is one of elements constituting the personal authentication system, and detects an image, for example, a face image, as an image for authenticating the user U. The face image detected by the imaging unit 1d is transmitted to the security system 3. Fig. 3 is a diagram showing an image P captured by the imaging unit of the registered terminal. Referring to fig. 3, for example, a plurality of users U1 and U2 may appear in the angle of view [ Ag ] captured by the imaging unit 1d of the registration terminal 1. In this case, the image pickup unit 1d detects the face image of the front-most user U1 with respect to the image pickup unit 1d, and transmits only the face image of the front-most user U1 to the security system 3.

Here, referring to fig. 2 before, the users U1, U2 of the elevator landing 400 may exchange the standing positions as described below until the car arrives at the elevator landing 400. In this case, the image capturing unit 1d transmits the face image of the same user to the security system 3a plurality of times.

Fig. 4 is (one of) diagrams for explaining detection of a face image of a user in the elevator system according to embodiment 1, and is a diagram of users U1 and U2 shown in fig. 2 before being replaced with their standing positions. Fig. 5 is a diagram showing an image P captured by the imaging unit of the registration terminal in the case of fig. 4. In this case, only the user U2 appears within the angle of view [ Ag ] photographed by the photographing section 1d of the registration terminal 1. Therefore, the image capturing unit 1d detects the face image of the user U2 and transmits only the face image of the user U2 to the security system 3.

Fig. 6 is a diagram (two) for explaining the detection of the face image of the user in the elevator system according to embodiment 1, and is a diagram in which the standing positions of the users U1 and U2 are replaced again. Fig. 7 is a diagram showing an image P captured by the imaging unit of the registration terminal in the case of fig. 6. In this case, the user U1 appears foremost again within the angle of view [ Ag ] captured by the imaging section 1d of the registration terminal 1. The image capturing unit 1d detects the face image of the front user U1 again, and transmits the face image of the user U1 to the security system 3 again.

As described above, when the user U1, U2 of the elevator hall 400 changes the standing position with respect to the registration terminal 1 while waiting for the car to arrive, the face image of the same user U1 is transmitted to the safety system 3a plurality of times.

In addition to the above, when the anteroposterior relationships between the users U1 and U2 are exchanged 2 times from the state shown in fig. 2 and 3, the face image of the same user U1 is transmitted to the security system 3a plurality of times.

In addition, although the configuration in which the imaging unit 1d detects the face image of the front user U1 and transmits the face image to the security system 3 has been described above, the same configuration is also applicable to the security system 3 in which only the face image of the front user U1 is acquired. Hereinafter, the user U1 and U2 will be collectively referred to as user U.

< input/output control System 2>

The input/output control system 2 controls input/output of various signals transmitted/received from each unit in the elevator system 10.

Method for managing the operation of an elevator installation

Next, an operation management method of the elevator apparatus according to embodiment 1 implemented by the elevator system 10 as described above will be described. The operation control method of the elevator apparatus described herein is a method of avoiding the addition of a repetitive predetermined number of passengers for the same user.

Fig. 8 is (one of) a flowchart showing an operation management method of an elevator apparatus according to embodiment 1, and shows a procedure of elevator number assignment performed in the operation management control system 7 a. Fig. 9 is a flowchart (second) showing an operation management method of an elevator apparatus according to embodiment 1, and shows a reset procedure of user information performed in the operation management control system 7 a. These flowcharts are implemented by an operation management program of an elevator apparatus included in the elevator system 10. Hereinafter, an operation management method of an elevator apparatus according to embodiment 1 will be described with reference to fig. 1 and other drawings as necessary, based on the flowcharts of fig. 8 and 9.

< step of ladder assignment >

First, the procedure of the elevator number assignment performed in the operation management control system 7a will be described with reference to the flowchart of fig. 8. In addition, this flow is periodically repeated.

[ step S001 ]

First, in step S001 shown in fig. 8, the input accepting unit 7aa determines whether or not user information is input. The user information is information transmitted from the elevator information transmitting unit 3f of the safety system 3. The input receiving unit 7aa proceeds to step S002 when determining that the user information is input (YES), and ends the process when determining that NO input is made (NO).

[ step S002 ]

In step S002, the input receiving unit 7aa receives the user information transmitted from the elevator information transmitting unit 3f of the safety system 3. In the example shown in fig. 2, the user information is, for example, user information on the user U1 located at the forefront of the registered terminal 1, and includes the user ID of the user U1 who has been face-authenticated by the security system 3, the departure floor and the destination floor of the user.

[ step S003 ]

In the next step S003, the authentication ID collating unit 7ab performs collation of whether or not the user ID included in the received user information is already registered in an acceptance table, not shown. When the verification result shows that the user ID is not registered in the acceptance table (NO), the authentication ID verification unit 7ab proceeds to step S004. On the other hand, when the verification result is that the user ID has already been registered in the acceptance table (YES), the authentication ID verification unit 7ab proceeds to step S008.

Thus, as described above with reference to fig. 2 to 7, when the duplicate user information of the same user U1 waiting for the car to arrive is transmitted from the safety system 3 to the operation management control system 7a and received by the input receiving unit 7aa, the routine proceeds to step S008.

[ step S004 ]

In step S004, the authentication ID collation unit 7ab registers the received user information. Here, the user information (user ID of user U, destination floor reservation information of the departure floor and destination floor) received by the input receiving unit 7aa in step S002 is registered in the receiving table, and the process proceeds to the next step S005.

[ step S005 ]

In step S005, the authentication ID collation unit 7ab performs a process of adding 1 to the held scheduled number of occupants.

[ step S006 ]

In step S006, the assignment arithmetic processing unit 7ac performs assignment arithmetic processing based on the added number of scheduled occupants, and assigns any one of the elevator cars 41 to the user ID registered in step S004. The assignment calculation process is performed based on the waiting time of the user, the number of passengers on each elevator car 41, and the instruction from the learning system 7 b.

[ step S007 ]

In step S007, the call registration instructing unit 7ad issues a call registration instruction to the car control device 42 of the elevator car 41 assigned by the assignment processing unit 7ac in step S006. At this time, the call registration instructing unit 7ad transmits the destination floor reservation information of the departure floor and the destination floor included in the acceptance table newly registered in step S004 to the hall control device 42 of the elevator number hall 41 assigned by the assignment processing unit 7 ac. Thus, the hall control device 42 of the elevator hall 41 that has received the command registers the hall/destination floor call. Then, the process proceeds to step S009.

[ step S008 ]

On the other hand, step S008 is a step that is entered after determining in step S003 that the user ID has already been registered in the acceptance table (YES). In step S008, the authentication ID collating unit 7ab extracts the elevator number ladder 41 already assigned to the same user ID in step S006 immediately before from the elevator number ladder 41. Then, the process proceeds to step S009.

[ step S009 ]

In step S009, the assignment number ladder notification instruction unit 7ae instructs the assignment number ladder to notify the notification unit 1c of the registration terminal 1 of the elevator number ladder 41 assigned to the user by the assignment calculation processing unit 7ac in step S006.

By the above processing, it is possible to assign elevator numbers avoiding the addition of a redundant scheduled passenger number for the same user U1.

< resetting step of user information >

Next, a procedure of resetting the user information performed in the operation management control system 7a is shown in accordance with the flowchart of fig. 9. In addition, this flow is periodically repeated.

[ step S101 ]

First, in step S101 shown in fig. 9, the authentication ID collation section 7ab determines whether or not any of the elevator cars 41 has arrived at the elevator hall 400 (see, for example, fig. 2). When it is determined that the arrival is reached (YES), the process proceeds to the next step S102, and when it is determined that the arrival is not reached (NO), the process is terminated.

[ step S102 ]

In step S102, the authentication ID checking section 7ab determines whether or not the destination floor reservation information is registered in the arriving elevator 41. The authentication ID collating section 7ab refers to the user information registered in the acceptance table, for example, and determines that there is destination floor reservation information when the landing floor to which the elevator 41 arrives is registered in the acceptance table as destination floor reservation information of the departure floor (YES), and proceeds to the next step S103.

On the other hand, the authentication ID collating section 7ab refers to the user information registered in the acceptance table, for example, and determines that there is NO destination floor reservation information (NO) when the destination floor reservation information having the landing floor where the elevator car 41 arrives as the departure floor is not registered in the acceptance table, and ends the processing.

[ step S103 ]

In step S103, the authentication ID checking unit 7ab instructs the car controller 42 of the arriving elevator car 41 to register the in-car destination floor. Thus, the elevator control device 42 of the arriving elevator car 41 lights the destination floor indication provided in the car 43 of the elevator, for example.

[ step S104 ]

In step S104, the authentication ID checking unit 7ab determines whether or not the reset condition is satisfied. The reset condition is set to the following condition, namely: it is determined that the user assigned to the elevator number 41 rides in the car of the arriving elevator number 41. Such a reset condition is set, for example, to a timing at which the arriving elevator 41 opens the door at the arrival floor or a timing at which the door is closed after the door is opened. When the authentication ID checking section 7ab determines that any of the reset conditions set is satisfied (YES), the process proceeds to step S105, and when it determines that the reset condition is not satisfied (NO), the process ends.

[ step S105 ]

In step S105, the authentication ID collation section 7ab resets the destination floor reservation information, which has the landing floor to which the elevator car 41 has arrived as the departure floor, among the user information registered in the acceptance table, and proceeds to step S106.

[ step S106 ]

In step S106, the authentication ID collating unit 7ab resets the user ID associated with the destination floor reservation information reset in step S105 among the user information registered in the acceptance table.

[ step S107 ]

In step S107, the authentication ID collating portion 7ab adds the in-car user to the elevator 41 assigned to the destination floor reservation information reset in step S105, and ends the reset procedure of the user information.

Thus, the operation management control system 7a can apply the hall assignment process described with reference to fig. 8, in which the addition of a predetermined number of passengers overlapping with each other for the same user is avoided, to the waiting period before the user enters the elevator hall 41. Therefore, even when the elevator car 41 departs in a state where the user U assigned to the arriving elevator car 41 does not take the elevator car 41, the user information of the user U in the operation management control system 7a is reset. Therefore, the user U who does not take the assigned elevator number 41 can take the newly assigned elevator number 41 by detecting the face image by the image pickup unit 1d of the registration terminal 1 again.

< effects of embodiment 1>

According to embodiment 1 described above, in the operation management of the elevator apparatus using the personal authentication technology, since the addition of the number of repeated scheduled occupants for the same user can be avoided, the number of scheduled occupants can be calculated with high accuracy. As a result, the operation efficiency of the elevator apparatus can be improved.

EXAMPLE 2

Elevator system

Fig. 10 is a block diagram showing a schematic configuration of an elevator system 10' according to embodiment 2. An elevator system 10 'according to embodiment 2 shown in the figure is different from the elevator system according to embodiment 1 in that an in-car registration terminal 1' is provided in addition to the registration terminal 1. Therefore, hereinafter, only the configuration of the in-car registration terminal 1 'and the difference caused by the installation of the in-car registration terminal 1' will be described, and the repetitive description of the same components as those of the elevator system according to embodiment 1 will be omitted.

< registration terminal 1' in car >

The in-car registration terminal 1' is a terminal device for registering a destination floor of an elevator user and performing personal authentication of the user. Fig. 11 is a diagram illustrating the installation position of the in-car registration terminal 1' in the elevator system according to embodiment 2. As shown in the figure, the in-car registration terminal 1' is provided inside the car 43.

This in-car registration terminal 1 'includes an information reading portion 1a, a destination floor registration portion 1b, a notification portion 1c, and an in-car imaging portion 1 d'. These parts are the same as those constituting the registration terminal 1 described in embodiment 1. However, the in-car registration terminal 1 'may have at least the in-car imaging section 1 d'.

The in-car imaging unit 1 d' is one of the elements constituting the personal authentication system, and detects a face image as an image for authenticating the user U in the car 43. The face image detected by the in-car imaging unit 1 d' is transmitted to the security system 3. The elevator information transmitting unit 3f of the safety system 3 transmits the user ID of the user whose face is authenticated by the personal authentication unit 3e in the face image transmitted from the in-car registration terminal 1' to the group management control system 7. At this time, the elevator information transmitting unit 3f transmits the user ID subjected to the face authentication to the group management control system 7 as in-car user information associated with the elevator number elevator in which the in-car registration terminal 1' is installed.

Method for managing the operation of an elevator installation

Next, an operation management method of the elevator apparatus according to embodiment 2 implemented by the elevator system 10' as described above will be described. In the operation management method of an elevator apparatus according to embodiment 2, the procedure of the elevator number assignment performed in the operation management control system 7a is the same as the procedure of the elevator number assignment in embodiment 1 described with reference to fig. 8. Therefore, hereinafter, the explanation of the step of allocating the elevator will be omitted, and the step of resetting the user information performed in the operation management control system 7a will be explained.

< step of ladder assignment >

Fig. 12 is a flowchart showing an operation management method of an elevator apparatus according to embodiment 2, and shows a reset procedure of user information performed in the operation management control system 7 a. Next, a reset procedure of the user information performed in the operation management control system 7a will be described with reference to fig. 12. In addition, this flow is periodically repeated.

[ step S201 ]

First, in step S201, the authentication ID collation section 7ab determines whether any one of the elevator cars 41 arrives at the elevator hall 400 (see fig. 2, for example). When it is determined that the arrival is reached (YES), the process proceeds to the next step S202, and when it is determined that the arrival is not reached (NO), the process is terminated.

[ step S202 ]

In step S202, the authentication ID collation unit 7ab determines whether or not a user in the car is detected in the arriving elevator 41. At this time, the authentication ID verification unit 7ab performs this determination based on whether or not the input reception unit 7aa has received in-car user information about the arriving elevator 41. The in-car user information is information in which the user ID of the face image detected and authenticated by the in-car imaging unit 1d 'is associated with the elevator number ladder 41 on which the in-car registration terminal 1' is installed.

When the input receiving unit 7aa receives the in-car user information on the arriving elevator 41, the authentication ID checking unit 7ab determines that an in-car user is detected (YES), and the process proceeds to step S203. On the other hand, when the input receiving unit 7aa does not receive the in-car user information on the arriving elevator 41, the process is terminated.

[ step S203 ]

In step S203, the authentication ID checking section 7ab determines whether or not the destination floor reservation information is registered in the arriving elevator 41. The authentication ID collating section 7ab refers to the user information registered in the acceptance table, for example, and determines that there is destination floor reservation information when the landing floor to which the elevator 41 arrives is registered in the acceptance table as destination floor reservation information of the departure floor (YES), and proceeds to the next step S204.

On the other hand, the authentication ID collating section 7ab refers to the user information registered in the acceptance table, for example, and determines that there is NO destination floor reservation information (NO) when the destination floor reservation information having the landing floor where the elevator car 41 arrives as the departure floor is not registered in the acceptance table, and ends the processing.

[ step S204 ]

In step S204, the authentication ID checking unit 7ab instructs the car controller 42 of the arriving elevator car 41 to perform in-car destination floor registration. Thus, the elevator control device 42 of the arriving elevator car 41 lights the destination floor indication provided in the car 43 of the elevator, for example.

[ step S205 ]

In step S205, the authentication ID checking unit 7ab determines whether or not the user ID included in the in-car user information received by the input receiving unit 7aa is registered at the hall. In this case, the authentication ID collating unit 7ab refers to the acceptance table, and performs this determination based on whether or not the user ID included in the in-car user information received by the input accepting unit 7aa is registered in the acceptance table.

That is, when the user ID of the user information in the car is registered in the acceptance table, the user ID is already registered in the acceptance table based on the detection of the face image in the registration terminal 1 provided at the hall. In this case, the authentication ID checking section 7ab determines that the registration is completed at the hall (YES), and proceeds to step S206. On the other hand, if the user ID of the in-car user information is not registered in the acceptance table, it is determined that the user ID has not detected a face image at the registration terminal 1 provided at the hall and registration has not been completed at the hall (NO), and the routine proceeds to step S208.

[ step S206 ]

In step S206, the authentication ID collating portion 7ab resets the destination floor reservation information having the landing floor to which the elevator car 41 has arrived as the departure floor among the user information registered in the acceptance table, and the process proceeds to step S207.

[ step S207 ]

In step S207, the authentication ID collating unit 7ab resets the user ID associated with the destination floor reservation information reset in step S206 among the user information registered in the acceptance table.

Thus, the operation management control system 7a can apply the hall assignment process described with reference to fig. 8, in which the addition of a predetermined number of passengers overlapping with each other for the same user is avoided, to the waiting period before the user enters the elevator hall 41.

[ step S208 ]

In step S208, the authentication ID collation unit 7ab adds 1 to the number of users in the car, who have detected the use company in the car in step S202, to the number of users in the car, who have kept the predetermined number of passengers. In this way, the reset step of the user information is ended.

< effects of embodiment 2>

According to embodiment 2 described above, the user information resetting process is performed based on the authentication of the face image of the user U detected by the in-car imaging unit 1 d'. Therefore, the user information reset process is performed based on the actual seating of the user U. Therefore, in addition to the effect of embodiment 1, the number of scheduled passengers can be calculated with higher accuracy, and the operation efficiency of the elevator apparatus can be further improved.
