Description

  An embodiment of the present invention relates to an elevator system including a landing destination floor registration device capable of registering a destination floor of a user at a landing.

  In a skyscraper or the like, in order to improve the space efficiency of the building, a double-deck elevator having a cab configured in two stages above and below is used as a means of vertical transportation in the building. When the landing destination floor registration device is applied to such a double deck elevator, the destination floor of the user registered at the landing is assigned to an upper car or a lower car.

  The car to which the user's destination floor is assigned is called an "assigned car". On the other hand, a car to which the user's destination floor is not assigned is called an “unassigned car”. Since the destination floor of the user is already registered in the assigned car, there is no need to register the destination floor in the car when the user gets on the assigned car.

Japanese Patent No. 6029617 Japanese Patent No. 4832886

  In the above-described double deck elevator, the upper car and the lower car may stop on the same floor depending on the operation mode (semi-double operation mode). For example, when the lower car responds to the fifth floor as an assigned car, the upper car, which is a non-allocated car, stops at the fifth floor before the lower car to lower the user. In such a case, the user waiting at the landing may mistakenly think that the car to be boarded has arrived, and may erroneously get on the upper car.

  An object of the present invention is to provide an elevator system that can prevent a user who has registered a destination floor from erroneously getting on an unallocated car.

  An elevator system according to one embodiment controls the operation of an elevator having two cars connected vertically. The elevator system includes a destination floor registration unit, an operation control unit, an erroneous boarding detection unit, and a notification control unit. The destination floor registration means registers the destination floor of the user at the landing. The operation control means allocates the destination floor of the user registered by the destination floor registration means to one of the elevator cars, and causes the elevator car to respond to the registered floor in which the destination floor is registered as the assigned car. . The erroneous boarding detection means detects erroneous boarding of the user to the unallocated car when the other car of the elevator stops at the registered floor as an unallocated car. The notification control means notifies the user when the erroneous boarding detection means detects the erroneous boarding of the user to the unallocated car.

In the present embodiment, a group management system including at least one double deck elevator is assumed. Further, in the present embodiment, as a control method of the group management system, a destination floor control system (DCS: Destination Control) using a hall destination floor registration device (HDC: Hall Destination Controller) capable of registering a destination floor of a user at the hall. System) is used.

(First embodiment)
FIG. 1 is a diagram showing a configuration of a landing of the double deck elevator according to the first embodiment.

  The landing destination floor registration devices 12a and 12b are installed at the landings 11a and 11b on each floor of the building. These landing destination floor registration devices 12a and 12b are used in combination with, for example, a security gate (not shown), and have a configuration in which the destination floor can be registered together with authentication using the ID card 14 of the user 13.

  FIG. 2 shows an example of the landing destination floor registration device 12a. The landing destination floor registration device 12b has the same configuration.

  The landing destination floor registration device 12a is provided with an ID reading device 15a for reading information of the ID card 14. ID (identification) information for identifying the user 13 and a destination floor (use floor) of the user 13 are recorded in the ID card 14 in advance. The ID reader 15a is a so-called "card reader", and reads information recorded on the ID card 14 in a non-contact manner by an electromagnetic guide system or the like.

  When the landing destination floor registration device 12a is used in combination with a security gate (not shown), if the user 13 is authenticated by the ID information recorded on the ID card 14, the gate can be opened to proceed to the landing 11a. At this time, the destination floor of the user 13 recorded on the ID card 14 together with the ID information is read.

  The landing destination floor registration device 12a is provided with a display device 16a composed of, for example, a liquid crystal panel. The display device 16a displays information on the destination floor of the user 13 read from the ID card 14 and the assigned car to which the destination floor is assigned.

  In the example shown in FIG. 2, the landing destination floor registration device 12a is provided with the ID reading device 15a. However, the ID reading device 15a may be independently installed near the landing destination floor registration device 12a.

  Further, in place of the ID reading device 15a, for example, a configuration in which a key input type operation panel 17 as shown in FIG. The operation panel 17 is provided with a plurality of numeric keys and registration keys, and the user 13 operates these keys to register a destination floor. The ID number may be registered together with the destination floor.

  Here, in the present embodiment, the camera 18a is installed near the landing destination floor registration device 12a. The camera 18a is composed of, for example, a small monitoring camera such as a vehicle-mounted camera, and photographs the user 13 who registers a destination floor at the landing 11a. The same applies to the other landing 11b. A camera 18b is installed near the landing destination floor registration device 12b, and photographs a user who registers a destination floor at the landing 11b.

  Although the example of FIG. 1 shows the configuration of the landings 11a and 11b on any two floors, the same applies to the landings on other floors, and the landing destination floor registration device and the camera are installed.

  A double deck elevator 21 is provided in the hoistway 20 of the building so as to be movable on each floor. The double deck elevator 21 has two cars (hereinafter, referred to as an upper car 22a and a lower car 22b) connected vertically. The upper car 22a and the lower car 22b are connected to each other via a floor adjustment mechanism 23 so as to be vertically movable.

  The upper car 22a is provided with a car door 24a, a camera 25a, and an announcement device 26a. The car door 24a opens and closes by driving a door motor (not shown) when the upper car 22a has landed on the landings 11a, 11b... On each floor.

  The camera 25a is installed above the entrance of the upper car 22a. Specifically, the lens portion of the camera 25a is installed in a curtain plate (not shown) that covers the upper part of the entrance of the upper car 22a with the lens portion facing the landing. The camera 25a is, for example, a small monitoring camera such as a vehicle-mounted camera, has a wide-angle lens, and can continuously capture an image of several frames (for example, 30 frames / second) per second. When the upper car 22a is opened at the landings 11a, 11b... On each floor, the state of the landings 11a, 11b.

  In addition, the installation location of the camera 25a is not limited to the curtain plate, and may be any location as long as the upper car 22a can take a picture of a user who gets on the upper car 22a when the door opens at the landing on each floor.

  The announcement device 26a is installed at an arbitrary position on the upper car 22a, and is used to make a voice announcement of a message or the like relating to a wrong ride.

  Similarly to the upper car 22a, the lower car 22b is provided with a car door 24b, a camera 25b, and an announcement device 26b.

  FIG. 4 is a diagram showing the configuration of the upper car 22a. The lower car 22b has the same configuration.

  A car door 24a is installed in front of the upper car 22a, and opens and closes by driving a door motor (not shown). In the vicinity of the car door 24a, a car operation panel 31a having various operation buttons including a destination floor button and the like, and a display 32a for displaying a current position, a driving direction, a destination floor, and the like are provided. In the “full DCS” in which the landing destination floor registration devices are installed on all floors, the destination floor button is not required on the car operation panel 31a.

  The camera 25a and the announcement device 26a shown in FIG. 1 are installed in the upper car 22a. Operations relating to the upper car 22a, including the opening and closing operations of the car door 24a, are controlled by a car control device 33a provided at an upper portion of the upper car 22a or the like.

  Since the lower car 22b has the same configuration as the upper car 22a, the illustration is omitted.

  FIG. 5 is a block diagram illustrating a configuration of the elevator system according to the first embodiment, and illustrates a configuration as a group management system including a plurality of elevators. At least one of these elevators includes the double deck elevator 21 shown in FIG. In the example of FIG. 5, the car A is the double deck elevator 21 and has an upper car 22a and a lower car 22b.

  Although only the landing destination floor registration device 12a is shown in the example of FIG. 5, the landing destination floor registration devices installed at the landings of each floor are actually connected to the group management control device 61.

  The landing destination floor registration device 12a includes an ID authentication unit 41 and an image recognition unit 42 as functions related to the present system.

  The ID authentication unit 41 authenticates the user based on the ID information of the ID card 14 read by the ID reading device 15a shown in FIG. In this case, when the information of the destination floor is recorded on the ID card 14, the information of the destination floor is read together with the ID information from the ID card 14 by the ID reading device 15a. It is sent to the group management control device 61 via the control unit.

  The image recognition unit 42 performs a recognition process on an image of the user captured by the camera 18a installed near the landing destination floor registration device 12a. In addition, as a method of ID authentication, a generally known method such as collation with an ID given to a valid user is used, and is not limited to a specific method. As for the image recognition method, a generally known method such as extraction and analysis of a feature (shape and the like) of the target object from a captured image including the target object is used, and is not limited to a specific method.

  In the double deck elevator 21, the car control device 33a provided in the upper car 22a is provided with an image recognition unit 51a, a notification control unit 52a, and an erroneous boarding detection unit 53a as functions related to the present system.

  The image recognizing unit 51a recognizes a user image captured by the camera 25a installed on the upper car 22a.

  The notification control unit 52a notifies the user through the announcement device 26a in the upper car 22a when the erroneous boarding is detected by the erroneous boarding detection unit 53a.

  When the upper car 22a is a non-allocated car having no destination floor of the user, the erroneous boarding detection unit 53a detects that the user gets on the upper car 22a by mistake. Specifically, the erroneous boarding detection unit 53a determines whether the same person has been identified by comparing the recognition result of the image captured by the camera 18a on the landing side with the recognition result of the image captured by the camera 25a on the car side. Judge as an incorrect ride.

  Here, the “mis-ride” includes a state (scheduled ride) in which the user intends to enter the unallocated car with the intention to ride.

  The same applies to the car control device 33b provided in the lower car 22b. The functions related to the present system include an image recognition unit 51b, a notification control unit 52b, and an erroneous boarding detection unit 53b.

  The image recognition unit 51b performs a recognition process on a user image captured by the camera 25b installed on the lower car 22b.

  The notification control unit 52b notifies the user through the announcement device 26b in the lower car 22b when the erroneous boarding of the user is detected by the erroneous boarding detection unit 53b.

  When the lower car 22b is a non-allocated car that does not have the destination floor of the user, the incorrect boarding detector 53b detects that the user gets on the lower car 22b by mistake. More specifically, the erroneous boarding detection unit 53b compares the recognition result of the image captured by the landing-side camera 18b with the recognition result of the image captured by the car-side camera 25b to identify the same person. Judge as an incorrect ride.

  In the example of FIG. 5, the car control devices 33a and 33b are provided with the erroneous boarding detection units 53a and 53b, and the car side detects erroneous boarding of the user. However, the car control device 62a or the group management control device is used. The erroneous boarding detection section 53a, 53b may be provided in 61, and the erroneous boarding of the user may be detected on the side of the car controller 62a or the group management controller 61.

  The group management control device 61 is a main control device that performs group management of the operation of a plurality of elevators, and is connected to the number control devices 62a, 62b, 62c,. Each of the number control devices 62a, 62b, 62c... Individually controls the operation of the corresponding elevator.

FIG. 6 is a block diagram showing a functional configuration of the group management control device 61.
The group management control device 61 includes a call registration unit 71, an operation control unit 72, and a display control unit 73 as functions related to the present system.

  The call registration unit 71 stores hall call information including the user ID, the destination floor, and information on the characteristics of the user. If image recognition is performed at the landing, a user image obtained as a result of the recognition is stored. Note that a hall call including a destination floor may be referred to as a “destination call”. FIG. 7 shows an example of the call registration unit 71. The registered floor in the figure is the floor where the user has registered the destination floor. For example, when the user registers the destination floor at the landing on the 5th floor, “5F” is the registered floor.

  The operation control unit 72 assigns the destination floor of the user to an optimal car in each car based on the hall call information stored in the call registration unit 71. In this case, if the double deck elevator 21 of the car A is to be allocated, the destination floor of the user is allocated to the upper car 22a or the lower car 22b.

  The display control unit 73 displays, on the display device 16a illustrated in FIG. 2, information on a car having a car (assigned car) to which the destination floor of the user is assigned by the operation control unit 72.

Next, the operation of the first embodiment will be described.
FIG. 8 is a flowchart showing the operation of the elevator system according to the first embodiment.

  Now, as shown in FIG. 1, it is assumed that a user 13 registers a destination floor using an ID card 14 at a landing 11a on an arbitrary floor.

  A landing destination floor registration device 12a is installed in front of the landing 11a. The landing destination floor registration device 12a is provided with an ID reading device 15a. When the user 13 brings the ID card 14 close to the ID reading device 15a, the ID information is read from the ID card 14 and given to the ID authentication unit 41 shown in FIG. 5 (step S101).

  When authenticating that the user 13 is a valid user (Yes in step S102), the ID authentication unit 41 acquires information on the destination floor from the ID card 14, and stores the ID information of the user 13 and the registered floor information. The information is sent to the group management controller 61 as hall call information together with the information (step S103).

  On the other hand, when the user 13 comes to the hall 11a, the user 13 is photographed by the camera 18a installed near the hall destination floor registration device 12a. The image recognition unit 42 recognizes the user 13 from the image captured by the camera 18a, and sends the recognition result to the group management control device 61 (Step S104). This recognition result is stored in the call registration unit 71 shown in FIG. 7 in association with hall call information (ID, destination floor, registered floor).

  In the group management control device 61, the operation control unit 72 selects an optimally efficient car from among the respective cars based on the hall call information stored in the call registration unit 71, and selects that car. Is assigned to the destination floor of the user 13 (step S105). The car to which the destination floor is assigned is called an “assigned car”.

  In this case, the assigned car is selected by the DCS assignment control method in consideration of the destination floor of the user 13. For example, it is assumed that the destination floor of the user 13 is “10F”. At this time, if the destination floor of another user is already assigned to each elevator as described below, the lower car of the A-unit (double deck elevator 21) having the same destination floor "10F" as the user 13 22b will be selected as the assigned car.

Unit A-Upper car: "11F", Lower car: "10F"
Unit B: "2F"
Unit C: "5F", "6F"
Since the destination floor allocation control in the DCS is known, detailed description thereof is omitted here.

  When the assigned car is determined, an assignment signal is sent from the operation control unit 72 of the group management control unit 61 to a corresponding one of the unit control units 62a, 62b, 62c,. For example, when the lower car 22b of the car A is determined as the assigned car, a lower car assignment signal is sent to the car A controller 62a, and the lower car 22b is driven to the registered floor "5F" ( Step S106).

  At this time, since "A car" is displayed as the assigned car on the display device 16a of the landing destination floor registration device 12a shown in FIG. 2, the user 13 may get on the A car. However, since only the "A car" is displayed on the display device 16a, for example, if the upper car 22a, which is a non-allocated car, stops first at the landing 11a to drop the user, the user 13 is mistaken for the upper car 22a. Sometimes get on.

  In order to prevent such erroneous riding, when the upper car 22a, which is an unallocated car, stops on the registered floor before the lower car 22b, which is an allocated car (Yes in step S107), the following erroneous riding is performed. Prevention processing is performed.

  That is, when the upper car 22a is opened at the landing 11a, the user 13 who gets on the upper car 22a is photographed by the camera 25a installed on the upper car 22a. The image recognition unit 51a provided in the car control device 33a recognizes the user 13 from the image captured by the camera 25a, and gives the recognition result to the erroneous boarding detection unit 53a (Step S108).

  On the other hand, the car control device 33a is provided with a recognition result of an image captured by the landing-side camera 18a from the group management control device 61 via the A-unit control device 62a. The erroneous boarding detection unit 53a of the car control device 33a compares the recognition result of the image captured by the landing camera 18a with the recognition result of the image captured by the car camera 25a, A ride is determined (step S109). In this case, if the user 13 obtained from the image captured by the camera 18a on the landing side is the same as the user obtained from the image captured by the camera 25a on the car side, it is determined that the vehicle has been erroneously boarded.

  In the case of erroneous boarding (Yes in step S109), the car control device 33a notifies the user 13 of the erroneous boarding through the notification control unit 52a before the upper car 22a closes the door and departs (step S109). S110).

  More specifically, a message relating to erroneous boarding is announced by voice from the announcement device 26a in the upper car 22a. In this case, before the user 13 gets on the upper car 22a, for example, as shown in FIG. 9, "This elevator does not go to the ** floor. Please get on the elevator that comes next." Voice message is announced. In addition, after the user 13 has boarded the upper car 22a, for example, as shown in FIG. 10, "Please get on the ** floor. Please get on the next elevator." Such a message is announced by voice.

  In addition, the notification method to the user is not limited to the voice announcement, for example, may be notified by a message display through a display device installed in a car or a hall, or may be notified by both voice and display .

  Whether the user 13 is before or after boarding can be determined from the image captured by the camera 25a on the car side. The “** floor” in the above message is the destination floor of the user 13, and information on the destination floor of the user 13 is transmitted from the group management control device 61 to the car control device via the A-unit control device 62 a. 33a.

  As described above, according to the first embodiment, when one of the cars of the double deck elevator responds as the assigned car, the user erroneously gets on the non-allocated car that arrives at the same recording floor prior to the assigned car. Can be prevented.

(Second embodiment)
Next, a second embodiment will be described.
In the first embodiment, when an erroneous boarding of a user is detected, the user is notified of the fact and is prompted to board the assigned car. On the other hand, in the second embodiment, the characteristics of the user are determined, and if the user has characteristics that are difficult to walk such as a wheelchair or an elderly person, the destination floor of the user is assigned to the unallocated car without notifying. Change the assignment and drive.

  FIG. 11 is a diagram showing a configuration of a landing of a double deck elevator according to the second embodiment.

  As in the first embodiment, landing destination floor registration devices 12a and 12b are installed at the landings 11a and 11b on each floor of the building, and cameras 18a and 18b are installed near the landing destination floor registration devices 12a and 12b, respectively. The landing destination floor registration devices 12a and 12b are used in combination with, for example, a security gate (not shown), and have a configuration in which the destination floor can be registered together with authentication using the ID card 82 of the user 81.

  Here, in the second embodiment, the user 81 is a wheelchair user. The ID and the destination floor are recorded on the ID card 82 of the user 81.

  FIG. 12 is a block diagram illustrating a configuration of an elevator system according to the second embodiment. The same parts as those in the configuration of FIG. 5 in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.

  The landing destination floor registration device 12a includes a user determination unit 43, a storage unit 44, and a database 45 in addition to an ID authentication unit 41 and an image recognition unit 42 as functions related to the present system.

  The user determination unit 43 determines the characteristics of the user based on the ID information of the user authenticated by the ID authentication unit 41 or the recognition result of the image recognition unit 42.

  Specifically, the user determination unit 43 searches the database 45 for user management based on the ID information of the user, and determines whether the user has a characteristic that makes walking difficult. When the use of a walking aid such as a wheelchair or a crutch is registered as attribute information in the database 45, it is determined that the user has a characteristic that makes walking difficult. If age information of a predetermined age or more is registered in the database 45, it is determined that the user has a characteristic that makes walking difficult.

  When the recognition result of the image recognition unit 42 is used, for example, if the captured image includes a walking aid such as a wheelchair or a crutch, it can be determined that the user has a characteristic that makes walking difficult. Also, if the age can be analyzed by face recognition, it can be determined that the user has a characteristic that makes walking difficult when the age is estimated to be equal to or higher than a predetermined age.

  The storage unit 44 is provided with a database 45 for user management. In this database 45, for a plurality of users who are permitted to use the elevator, in addition to the basic information such as the ID, name, and gender of each user, age information and attribute information (for example, the Usage, visual impairment, etc.) are registered.

  The user management unit 43, the storage unit 44, and the database 45 provided in the landing destination floor registration device 12a are provided in the group management control device 61, and the group management control device 61 determines the characteristics of the user. Is also good.

  On the other hand, in the double-deck elevator 21, the car control device 33a provided in the upper car 22a has a function related to the present system, in addition to the image recognition unit 51a, the notification control unit 52a, and the erroneous boarding detection unit 53a. A control unit 54a is provided.

  The door opening control unit 54a sets the door opening time of the upper car 22a to a fixed time longer than usual when the erroneous boarding detection unit 53a detects an erroneous boarding to the upper car 22a of the user having the characteristic that it is difficult to walk. Extend.

  The same applies to the car control device 33b provided in the lower car 22b. As a function related to the present system, a door opening control unit 54b is provided in addition to the image recognition unit 51b, the notification control unit 52b, and the incorrect boarding detection unit 53b. Have been.

  The door opening control unit 54b sets the door opening time of the lower car 22b to a fixed time longer than usual when the erroneous boarding detection unit 53b detects the erroneous boarding of the user having the characteristic of difficulty walking in the lower car 22b. Extend.

FIG. 13 is a block diagram showing a functional configuration of the group management control device 61.
The group management control device 61 includes an assignment change unit 74 as functions related to the present system, in addition to the call registration unit 71, the operation control unit 72, and the display control unit 73.

  The assignment change unit 74 changes the destination floor of the user from the assigned car to the non-assigned car when the user having the characteristic of having difficulty walking can mistake the unassigned car (the upper car 22a or the lower car 22b). I do.

Next, the operation of the second embodiment will be described.
FIG. 14 is a flowchart showing the operation of the elevator system according to the second embodiment.

  Now, as shown in FIG. 11, it is assumed that a user 81 registers a destination floor using an ID card 82 at a landing 11a on an arbitrary floor.

  A landing destination floor registration device 12a is installed in front of the landing 11a. The landing destination floor registration device 12a is provided with an ID reading device 15a. When the user 81 brings the ID card 82 close to the ID reading device 15a, the ID information is read from the ID card 82 and given to the ID authentication unit 41 shown in FIG. 12 (step S201).

  Upon authenticating that the user 81 is a valid user (Yes in step S202), the ID authentication unit 41 acquires destination floor information from the ID card 82, and stores the ID information of the user 81 and the registered floor. The information is sent to the group management control device 61 as hall call information together with the information (step S203).

  On the other hand, when the user 81 comes to the hall 11a, the user 81 is photographed by the camera 18a installed near the hall destination floor registration device 12a. The image recognition unit 42 recognizes the user 81 from the image captured by the camera 18a, and sends the recognition result to the group management control device 61 (Step S204). This recognition result is stored in the call registration unit 71 shown in FIG. 7 in association with hall call information (ID, destination floor, registered floor).

  Here, in the second embodiment, the characteristics of the user 81 are determined by the user determining unit 43 (Step S205). In this case, for example, if the use of a walking aid such as a wheelchair is registered as attribute information in the user management database 45, the attribute information is searched from the database 45 based on the ID information of the user 81. Thus, it can be determined that the user 81 has characteristics that make walking difficult. However, for example, when the user 81 is temporarily using crutches in an accident or the like, the use of crutches may not be registered as attribute information in the database 45. Therefore, an image captured by the camera 18a is used. That is, by recognizing the crutches included in the captured image, it can be determined that the user 81 has characteristics that make walking difficult.

  Note that a configuration may be used in which the characteristics of the user 81 are determined using both the ID information of the user 81 and the captured image. If the age of the user 81 is registered in the database 45, it may be determined that the user 81 who is older than a predetermined age has difficulty walking.

  In addition, the age information and the attribute information of the user may be registered in the ID card 82 in advance, and the characteristics of the user may be determined based on the information.

  The characteristic information of the user 81 obtained by the user judging unit 43 is given to the group management control device 61 and stored in the call registration unit 71 together with information such as the ID of the user 81, the destination floor, and the registered floor.

  In the group management control device 61, the operation control unit 72 selects an optimally efficient car from among the respective cars based on the hall call information stored in the call registration unit 71, and selects that car. Is assigned to the destination floor of the user 81 (step S206). The car to which the destination floor is assigned is called an “assigned car”. In this case, as described in the first embodiment, the assigned car is selected by the DCS assignment control method in consideration of the destination floor of the user 81.

  When the assigned car is determined, an assignment signal is sent from the operation control unit 72 of the group management control unit 61 to a corresponding one of the unit control units 62a, 62b, 62c,. For example, when the lower car 22b of the car A is determined as the assigned car, a lower car assignment signal is sent to the car A controller 62a, and the lower car 22b is driven to the registered floor "5F" ( Step S207).

  At this time, the display device 16a of the landing destination floor registration device 12a shown in FIG. 2 only displays "A car" as an assigned car, so that, for example, the upper car 22a, which is a non-assigned car, needs If the user 81 stops first, the user 81 may accidentally get on the upper car 22a.

  In order to prevent such erroneous riding, when the upper car 22a, which is an unallocated car, stops on the registered floor before the lower car 22b, which is an assigned car (Yes in step S208), the following erroneous riding occurs. Prevention processing is performed.

  That is, when the upper car 22a opens at the landing 11a, the user 81 who gets on the upper car 22a is photographed by the camera 25a installed on the upper car 22a. The image recognition unit 51a provided in the car control device 33a recognizes the user 81 from the image captured by the camera 25a, and gives the recognition result to the erroneous boarding detection unit 53a (Step S209).

  On the other hand, the car control device 33a is provided with a recognition result of an image captured by the landing-side camera 18a from the group management control device 61 via the A-unit control device 62a. The erroneous boarding detection unit 53a of the car control device 33a compares the recognition result of the image taken by the camera 18a on the hall side with the recognition result of the image taken by the camera 25a on the car side, A ride is determined (step S210). In this case, if the user 81 obtained from the image captured by the camera 18a on the landing side is the same person as the user obtained from the image captured by the camera 25a on the car side, it is determined that the vehicle is erroneous.

  Here, in the case of erroneous boarding (Yes in step S210), the erroneous boarding detection unit 53a determines whether the user is a specific user who has difficulty walking based on the characteristic information of the user 81 obtained from the group management control device 61. It is determined whether or not it is (step S211).

  If the user is not a specific user who is difficult to walk (No in step S211), the car control device 33a performs the notification control unit 52a before the upper car 22a closes the door and departs, as in the first embodiment. The user 81 is notified that the vehicle is erroneously boarded (step S214).

  When it is a specific user who has difficulty walking (Yes in step S211), the car control device 33a prohibits the notification to the user 81 and changes the assignment to the group management control device 61 via the A-unit control device 62a. To instruct. Thus, the group management control device 61 changes the assignment of the destination floor of the user 81 assigned to the lower car 22b to the upper car 22a through the assignment changing unit 74 (step S212). By this allocation change, the contents of the call registration unit 71 shown in FIG. 7 are also rewritten, and thereafter, the upper car 22a is operated as a new allocated car for the user 81.

  In addition, the car control device 33a extends the door opening time of the upper car 22a by a certain time (for example, 10 seconds) than usual through the door opening control unit 54a so that the user 81 is not missed (step S213). .

  Also, when the user 81 (a specific user who has difficulty walking) gets off at the destination floor of the user 81, the car control device 33a sets the door opening time of the upper car 22a to be longer than usual through the door opening control unit 54a. Is extended by a certain time (for example, 10 seconds) so that the user 81 is not delayed getting off.

  As described above, according to the second embodiment, when a user mis-rides on a non-allocated car, the user is not notified when the user has a characteristic that makes walking difficult, such as using a wheelchair or the elderly. The destination floor of the user can be reassigned to a non-allocated car for operation. At that time, by extending the door opening time by a certain time longer than usual, it is possible to prevent the user from falling behind.

(Modification)
In the first and second embodiments, a camera is used as a method for detecting a user's erroneous boarding. However, by reading information of the user's ID card in the hall and the car, the user's erroneous boarding can be detected. It is good also as a structure which detects.

  In this case, the cameras 18a and 18b installed on the landing side and the cameras 25a and 25b installed in the upper and lower cars are not necessarily required. Instead, an ID reader 27a is installed in the upper car 22a and the lower car 22b, for example, as shown in FIG.

  Thus, when the user 13 gets on a non-allocated car (for example, the upper car 22a), the ID information of the ID card 14 is read by the ID reader 27a installed in the upper car 22a. If this ID information is the same as the ID information of the ID card 14 read by the ID reading device 15a of the landing destination floor registration device 12a, it is understood that the user 13 has erroneously boarded the unallocated car.

  However, since the ID information of the ID card 14 cannot be read unless the user 13 enters the upper car 22a, the camera 25a installed in the upper car 22a as in the first embodiment is used. It is preferable to detect and notify a wrong ride before the user 13 enters the car.

  According to at least one embodiment described above, it is possible to provide an elevator system that can prevent a user who has registered a destination floor from erroneously getting on an unallocated car.

  In the above embodiments, a double-deck elevator having two cars has been described as an example. However, an elevator in which three or more cars are connected may be used in the same manner as described above. It is possible to prevent the user from erroneously getting on a non-allocated car in the car.

  In sum, although some embodiments of the present invention have been described, these embodiments have been presented by way of example only, and are not intended to limit the scope of the inventions. These new embodiments can be implemented in other various forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. These embodiments and their modifications are included in the scope and gist of the invention, and are also included in the invention described in the claims and their equivalents.
