Summary of the Invention

Problems to be Solved by the Invention

[0005] On the other hand, when using an elevator, the tolerance for waiting time varies depending on the user or the usage situation. For example, in recent years, mobile terminals such as smartphones have become widespread. Therefore, when an elevator user watches content or performs a search operation using such a mobile terminal during the waiting time, the waiting time does not become a hardship, and there are cases where a certain amount of long waiting time is tolerated.

[0006] In view of this, there is a need for a technology to provide a service with a higher satisfaction rate to more users in consideration of the degree of tolerance for the waiting time for each user as described above.

[0007] The present invention has been made in view of the above circumstances, and an object thereof is to provide an elevator group management device and an elevator group management method for performing elevator group management so as to improve the satisfaction of elevator users.

Means for Solving the Problems

[0008] According to an embodiment for achieving the above object, an elevator group management device is communicably connected to a plurality of elevators, and includes a response priority calculation unit, a first determination unit, and an allocation control unit. The response priority calculation unit calculates a response priority when allocating an elevator that responds to a registered landing call for each floor in a building. The first determination unit determines, for each floor in the building, whether or not there is a waiting permitted user who is a waiting user allowing a waiting time longer than a predetermined value at an elevator landing. The allocation control unit allocates an elevator that responds to a registered landing call based on the response priority. Further, the response priority calculation unit calculates the response priority of a floor where it is determined in the first determination unit that there is a waiting permitted user at the landing to be lower than the response priority of a floor where it is determined that there is no waiting permitted user at the landing.

Mode for Carrying Out the Invention

[0010] Hereinafter, as an embodiment of the present invention, an elevator system 1 using an elevator group management device for managing a plurality of elevators in a building will be described.

[0011] <Configuration of Elevator System Using Elevator Group Management Device According to One Embodiment> FIG. 1 is an overall view showing the configuration of an elevator system 1 according to the present embodiment. The elevator system 1 includes Elevator 10A of Machine A, Elevator 10B of Machine B, and Elevator 10C of Machine C installed in a 15-story building, landing call registration devices 21-1 to 21-15, camera devices 22-1 to 22-15, and speaker devices 23-1 to 23-15 provided at each elevator landing (hereinafter simply referred to as "landing") FL1 to FL15 in the building, and an elevator group management device (hereinafter simply referred to as "group management device") 30. The group management device 30 is installed in the upper part of the hoistway and is communicably connected to Elevator 10A of Machine A, Elevator 10B of Machine B, Elevator 10C of Machine C, landing call registration devices 21-1 to 21-15, camera devices 22-1 to 22-15, and speaker devices 23-1 to 23-15.

[0012] Hereinafter, when it is not specified which of the landings FL1 to FL15 it is, it is described as landing FL.

[0013] In the present embodiment, the case where three elevators are installed in the building will be described, but it is not limited thereto, and two or four or more elevators may be installed. Also, in the present embodiment, the case where the number of floors in the building is 15 will be described, but it is not limited thereto, and any number of floors of two or more may be used.

[0014] The Elevator 10A of Machine A includes a hoisting machine 11A installed at the upper part of the hoistway, a car 13A suspended at one end of a rope 12A passed around the hoisting machine 11A, and a Control Device 15A of Machine A connected to the hoisting machine 11A via a signal line and connected to the car 13A via a tail cord 14A. Since the Elevator 10B of Machine B and the Elevator 10C of Machine C have the same configuration as the Elevator 10A of Machine A, detailed descriptions thereof are omitted.

[0015] The Landing Call Registration Devices 21-1 to 21-15 are devices for users in the landings FL1 to FL15 to perform landing call registration operations respectively. The Camera Devices 22-1 to 22-15 are devices for photographing the landings FL1 to FL15 respectively and transmitting the imaging information to the Group Management Device 30. The Speaker Devices 23-1 to 23-15 are devices for outputting the voice information transmitted from the Group Management Device 30 to the landings FL1 to FL15 respectively.

[0016] Figure 2 is a block diagram showing the detailed configuration of the Group Management Device 30. The Group Management Device 30 manages the Elevator 10A of Machine A, the Elevator 10B of Machine B, and the Elevator 10C of Machine C as a group, and includes a Storage Unit 31 and a CPU 32.

[0017] The Storage Unit 31 includes a Landing Call Registration Unit 311 and a Response Priority Storage Unit 312. The Landing Call Registration Unit 311 registers the information of the landing calls generated based on the operations performed by the users using any of the Landing Call Registration Devices 21-1 to 21-15. The Response Priority Storage Unit 312 stores the information of the response priority calculated by the CPU 32 as described later.

[0018] The CPU 32 is, for example, a CPU (Central Processing Unit) provided in a general-purpose microcomputer, and constitutes one or more of the following information processing units by installing and executing a predetermined elevator group management program.

[0019] The CPU 32 includes an operation information acquisition unit 321, an imaging information acquisition unit 322, a first determination unit 323, a response priority calculation unit 324, an allocation control unit 325, an operation instruction unit 326, an information output control unit 327, and a second determination unit 328.

[0020] The operation information acquisition unit 321 acquires information indicating the operation status of the elevator 10A of Machine A from the control device 15A of Machine A, acquires information indicating the operation status of the elevator 10B of Machine B from the control device 15B of Machine B, and acquires information indicating the operation status of the elevator 10C of Machine C from the control device 15C of Machine C.

[0021] The imaging information acquisition unit 322 acquires the imaging information captured by the camera devices 22-1 to 22-15. The first determination unit 323 determines, for each floor, whether there is a waiting permitted user who is a waiting user allowing a waiting time longer than a predetermined value (for example, one minute) in the elevator landing. In the present embodiment, the first determination unit 323 recognizes a waiting user who is visually recognized with a mobile terminal, detected by analyzing the imaging information acquired by the imaging information acquisition unit 322, as a waiting permitted user.

[0022] The response priority calculation unit 324 calculates, for each floor, a response priority which is the priority when allocating an elevator to respond to the hall call registered in the hall call registration unit 311. At this time, the response priority calculation unit 324 calculates the response priority of the floor where it is determined by the first determination unit 323 that there is a waiting permitted user in the landing to be lower than the response priority of the floor where it is determined that there is no waiting permitted user in the landing. Further, the response priority calculation unit 324 increases the response priority of the floor where it is determined by the second determination unit 328 described later that the waiting user who was visually recognized with a mobile terminal in the landing reacted to the voice information.

[0023] When a landing call is registered in the landing call registration unit 311, the allocation control unit 325 allocates an elevator that responds to the registered landing call based on the information acquired by the operation information acquisition unit 321 and the response priority of each floor stored in the response priority storage unit 312. Specifically, among the plurality of landing calls registered in the landing call registration unit 311, the allocation control unit 325 allocates an elevator that responds to each landing call so that the car arrives earlier as the response priority of the floor where the call occurred is higher.

[0024] The operation instruction unit 326 instructs the control device of the elevator allocated by the allocation control unit 325 to execute a response operation by transmitting information on the landing call to be responded to. The information output control unit 327 causes a speaker device on the floor determined by the first determination unit 323 to be a floor where a waiting user viewing a mobile terminal is present in the landing FL to output predetermined voice information. The second determination unit 328 analyzes the imaging information acquired by the imaging information acquisition unit 322 and determines whether or not the waiting user who viewed the mobile terminal in the landing FL reacted to the output voice information.

[0025] <Operation of Elevator System 1 According to an Embodiment> The operation of the elevator system 1 according to this embodiment will be described. During the operation of the elevator system 1, the operation information acquisition unit 321 of the group management device 30 acquires information indicating the operation status of the elevator 10A of car A from the control device 15A of car A, information indicating the operation status of the elevator 10B of car B from the control device 15B of car B, and information indicating the operation status of the elevator 10C of car C from the control device 15C of car C at predetermined time intervals. Also, the imaging information acquisition unit 322 sequentially acquires the imaging information captured by the camera devices 22-1 to 22-15 at predetermined time intervals.

[0026] Figure 3 is a flowchart showing the response priority update process executed by the group management device 30 for each floor during the operation of the elevator system 1.

[0027] When the group management device 30 executes the response priority update process for the first floor, the first determination unit 323 analyzes the imaging information acquired by the imaging information acquisition unit 322 from the camera device 22-1 to determine whether there is a waiting user visually recognizing a mobile terminal at the entrance FL1 on the first floor (S1). The mobile terminal is a terminal such as a smart device carried by the waiting user.

[0028] When a waiting user visually recognizing a mobile terminal enters the entrance FL1 on the first floor, the first determination unit 323 detects this based on the imaging information captured by the camera device 22-1.

[0029] When the first determination unit 323 detects that a waiting user visually recognizing a mobile terminal has entered the entrance FL1 on the first floor (``YES'' in S1), the response priority calculation unit 324 performs a process of lowering the response priority of the first floor stored in the response priority storage unit 312 (S2).

[0030] After that, when a certain period of time, for example, a period of about 30 seconds to 1 minute set in advance, has elapsed (``YES'' in S3), the group management device 30 executes a process of updating the response priority of the first floor stored in the response priority storage unit 312 (S4). The group management device 30 repeats the processes of steps S3 and S4 until there is no waiting user visually recognizing a mobile terminal on the first floor. When there is no waiting user visually recognizing a mobile terminal, it returns to step S1.

[0031] The group management device 30 executes the processes of steps S1 to S5 for all floors in the building. Thereby, the response priority of the floor where there is a waiting user visually recognizing a mobile terminal is appropriately adjusted.

[0032] A specific example of the update process of the response priority for each floor executed in this way and the elevator allocation process executed for the generated entrance calls will be described with reference to FIGS. 4 and 5.

[0033] FIG. 4 is an explanatory diagram of the elevator allocation process executed for the generated landing call at a predetermined timing. At this timing, since there is no user visually recognizing the mobile terminal in the landings on the 1st to 3rd floors, the first determination unit 323 does not detect a waiting user visually recognizing the mobile terminal ( "NO" in S1), and the response priority calculation unit 324 calculates the response priority "0" for the 1st to 3rd floors and stores it in the response priority storage unit 312.

[0034] Here, when a landing call occurs on the 1st, 2nd, and 3rd floors, the information of the generated landing call is registered in the landing call registration unit 311. When the information of the landing call is registered, the allocation control unit 325 allocates an elevator that responds to the generated landing call based on the information acquired by the operation information acquisition unit 321 and the response priority of each floor stored in the response priority storage unit 312. In this example, since there is no difference in the response priority of each floor, any elevator is allocated to each landing call so that the total waiting time of the waiting users in the building is minimized.

[0035] Specifically, the car 13A of elevator 10A is on the 15th floor, the car 13B of elevator 10B is between the 5th and 14th floors (not shown), and the car 13C of elevator 10C is near the 5th floor. In this state, elevator 10A is allocated to the landing call generated on the 3rd floor, elevator 10C is allocated to the landing call generated on the 2nd floor, and elevator 10B is allocated to the landing call generated on the 1st floor. At this time, the time (predicted arrival time) required for the car 13A to respond to the landing call and arrive at the 3rd floor is 70 seconds, and the time required for the car 13C to respond to the landing call and arrive at the 2nd floor is 5 seconds.

[0036] Based on the information allocated by the allocation control unit 325, the operation instruction unit 326 transmits the information of the landing call generated on the 3rd floor to the control device 15A of elevator 10A, transmits the information of the landing call generated on the 1st floor to the control device 15B of elevator 10B, and transmits the information of the landing call generated on the 2nd floor to the control device 15C of elevator 10C.

[0037] Here, when one waiting user who visually recognizes a mobile terminal enters the first-floor landing FL1, the first determination unit 323 determines, based on the imaging information captured by the camera device 22-1, that there is one waiting user who visually recognizes a mobile terminal on the first floor. Also, when three waiting users who visually recognize a mobile terminal enter the second-floor landing FL2, the first determination unit 323 determines, based on the imaging information captured by the camera device 22-2, that there are three waiting users who visually recognize a mobile terminal on the second floor (''YES'' in S1).

[0038] When the first determination unit 323 detects these users, the response priority calculation unit 324 performs processing to lower the response priority to the floor where the detected users are located (S2). Specifically, for each floor where the detected users are located, the response priority is newly calculated based on the number of detected waiting users, and the information in the response priority storage unit 312 is updated with the calculated value.

[0039] For example, since the response priority calculation unit 324 detects one waiting user who visually recognizes a mobile terminal on the first floor, it calculates the new response priority ''-1'' for the first floor and updates the response priority for the first floor stored in the response priority storage unit 312 with this value. Also, since the response priority calculation unit 324 detects three waiting users who visually recognize a mobile terminal on the second floor, it calculates the new response priority ''-3'' for the second floor and updates the response priority for the second floor stored in the response priority storage unit 312 with this value.

[0040] FIG. 5 is an explanatory diagram showing an example in the case of changing the elevator allocation content for each landing call allocated as shown in FIG. 4 based on the updated response priority. As described above, when the response priority is updated, the second floor has a lower response priority than the third floor. However, in the state allocated as shown in FIG. 4, the car 13C that responds to the landing call on the third floor arrives earlier at the floor where the landing call occurs than the car 13A that responds to the landing call on the first floor, and thus it is not consistent with the response priority.

[0041] Therefore, as shown in Fig. 5, the allocation control unit 325 considers changing the elevator that responds to the landing call generated on the third floor from elevator 10A to elevator 10C, and changing the elevator that responds to the landing call generated on the second floor from elevator 10C to elevator 10A.

[0042] When the allocation is changed in this way, the predicted arrival time for the landing call on the third floor becomes 5 seconds, which is 65 seconds shorter than the predicted arrival time of 70 seconds at the first allocation, and the score of the improvement effect is calculated as 65. Here, if the score imposed as a penalty due to this change is 0 and the threshold score of the improvement effect required for the execution of the change is set in advance to 60, since the calculated score of 65 exceeds the threshold score of 60, the change is executed.

[0043] By changing the allocation in this way, it is possible to make car 13C respond earlier to the third floor, where the response priority is higher than that of the second floor, and make car 13A respond later to the second floor, where the response priority is lower than that of the third floor, thus achieving consistency with the response priority.

[0044] The operation instruction unit 326 instructs the control device of the elevator allocated by the allocation control unit 325 to change the response operation by transmitting the information of the changed landing call.

[0045] In step S2, after the response priority calculation unit 324 performs the process of lowering the response priority to the floor where the detected user is located, when a certain period of time has elapsed (``YES'' in S3), the group management device 30 executes the process of updating the response priority for each floor stored in the response priority storage unit 312 (S4).

[0046] An example of an update process for updating the response priority executed by the response priority calculation unit 324 will be described. First, the information output control unit 327 causes the speaker devices 23-1 on the first floor and 23-2 on the second floor, which are the floors where the waiting users viewing the mobile terminal are detected, to output announcement information notifying that the arrival of the elevator car is delayed and the waiting time is long. After the output of this announcement information, the second determination unit 328 determines whether there is a waiting user who has reacted to the announcement information among the waiting users viewing the mobile terminal based on the imaging information of the first and second floors for which the imaging information acquisition unit 322 has acquired the announcement information and for which the announcement information has been output.

[0047] When the second determination unit 328 detects that there is a waiting user who has shown a reaction by being concerned about the announcement information, such as looking away from the mobile terminal, at the landing FL on the floor where the announcement information has been output, the response priority calculation unit 324 recognizes that although these waiting users are viewing the mobile terminal, the degree of concentration is low, and updates the response priority of the floor where these waiting users are located based on the number of detected waiting users.

[0048] For example, as shown in FIG. 6, when announcement information is output from the speaker device 23-1 on the first floor and the speaker device 23-2 on the second floor, and among the three waiting users viewing the mobile terminal on the second floor, two have reacted to the announcement information, the response priority calculation unit 324 calculates a correction value of “+2” for the response priority on the second floor. The response priority calculation unit 324 adds the calculated correction value of “+2” to the response priority of “-3” on the second floor stored in the response priority storage unit 312 to calculate and update a new response priority of “-1” on the second floor.

[0049] Here, with respect to the first floor where the waiting users viewing the mobile terminal did not react to the announcement information, the response priority calculation unit 324 recognizes that the waiting users viewing the mobile terminal are concentrated on the mobile terminal, and maintains the response priority lowered in step S2 as it is.

[0050] When the response priority is updated in this way, the allocation control unit 325 appropriately changes the allocation of the elevator that responds to the registered landing calls based on the information acquired by the operation information acquisition unit 321 and the updated response priority of each floor.

[0051] The operation instruction unit 326 instructs the change of the response operation by transmitting the information of the changed landing call to the control device of the elevator allocated by the allocation control unit 325.

[0052] According to the above embodiment, regarding the landing calls generated on the floors where there are waiting users who can tolerate the long waiting time of the elevator, by lowering the priority of responding to those landing calls, the satisfaction of all the waiting users in the building regarding the waiting time of the elevator can be improved.

[0053] In the above-described embodiment, the response priority calculation unit 324 calculates the number of waiting users who are visually recognized with mobile terminals for each floor, and the higher the calculated number, the lower the calculated response priority. However, it is not limited to this. The response priority calculation unit 324 may calculate, for each floor, the ratio of the number of waiting users who are visually recognized with mobile terminals to the number of all waiting users, and the lower the calculated value, the lower the calculated response priority.

[0054] Also, in the above-described embodiment, the response priority calculation unit 324 calculates the number of waiting users who responded to the voice information among the waiting users who are visually recognized with mobile terminals, and the higher the calculated number, the higher the response priority is updated. However, it is not limited to this. The response priority calculation unit 324 may calculate, for each floor, the ratio of the number of waiting users who responded to the voice information to the number of waiting users who are visually recognized with mobile terminals, and the higher the calculated value, the higher the response priority is updated. Thereby, it is possible to prevent the satisfaction of using the elevator from decreasing as much as possible for the waiting users other than those who can tolerate waiting and who do not use mobile terminals or the like.

[0055] In the above-described embodiment, the response priority calculation unit 324 may calculate the response priority for a floor where it is determined in the first determination unit 323 that both the waiting permitted user and the waiting users other than the waiting permitted user are at the landing FL to be higher than the response priority for a floor where it is determined that only the waiting permitted user is at the landing FL. Thereby, it is possible to prevent the satisfaction level of elevator use from decreasing as much as possible for waiting users other than the permitted users who are not using a mobile terminal or the like.

[0056] In the above-described embodiment, the response priority calculation unit 324 may calculate the response priority based on preset indexes according to the floor or according to the time zone. For example, regarding the first floor which is the entrance floor of the building, since the number of users is large, the response priority reduction width when there is a waiting permitted user may be made smaller than that of other floors. Also, since the elevator is congested during the morning commuting time zone and the lunch break time zone, the response priority may not be adjusted during these time zones. Thereby, it is possible to avoid an increase in the number of users whose satisfaction level of elevator use decreases.

[0057] In the above-described embodiment, the first determination unit 323 may recognize a waiting user wearing earphones as a waiting permitted user. Also, the second determination unit 328 may recognize a person wearing earphones among the waiting permitted users as a person concentrating on a mobile terminal, and may maintain the response priority lowered in step S2 as it is.

[0058] In the above-described embodiment, the first determination unit 323 may register in advance feature information such as face authentication information of a user who has a registered intention to permit a waiting time longer than a predetermined value, and when the imaging information acquisition unit 322 analyzes the acquired imaging information and detects a registered user, the detected user may be recognized as a waiting permitted user. Thereby, it is possible to perform elevator group management with higher accuracy in consideration of the user's intention.

[0059] Also, in the above-described embodiment, the first determination unit 323 may recognize a waiting user who has taken an action indicating an intention to allow a waiting time longer than a predetermined value as a waiting-allowing user. For example, the information output control unit 327 generates message information for inquiring whether to allow a waiting time longer than a predetermined value, and transmits it to the mobile terminal of a waiting user who has entered the landing FL by short-range wireless communication or the like via a wireless communicator installed at the landing FL on each floor. When the group management device 30 acquires information on an operation indicating an intention to allow a long waiting time that the user has performed on the mobile terminal in response to this message information, the first determination unit 323 may recognize this user as a waiting-allowing user. Thereby, elevator group management can be performed with higher accuracy in consideration of the user's intention.

[0060] Also, in the above-described embodiment, when the allocation control unit 325 considers changing the allocation of the elevator to a landing call, if the waiting time of the waiting users on any floor when changed exceeds a predetermined value (for example, 3 minutes), the allocation change may not be executed. Thereby, it is possible to avoid the user's waiting time from becoming excessively long.

[0061] Although some embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the gist 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 its equivalent scope.
