Description

Embodiments of the present invention relate to an elevator group management device and an elevator group management method.

In elevator systems that manage multiple elevators in a group, elevator halls in a building may be equipped with elevator hall destination floor registration devices that allow users to specify a destination floor and make an elevator hall call operation. In such elevator systems, each time a user operates the elevator hall destination floor registration device to specify a destination floor, the elevator to be used is assigned to the user who performed the operation, and the identification information of the assigned elevator is notified to the user.

When managing multiple elevators in a group, the elevators can be operated efficiently by assigning the same elevator to multiple users who have similar elevator usage patterns, such as those traveling to the same destination floor.

JP 2022-40504 A

As mentioned above, there are cases where it is preferable to assign the same elevator to multiple users and have them ride together. However, there are also cases where it is preferable to avoid users riding in the same car depending on the relationship between the users, such as when the users have similar elevator usage patterns but work for the same industry or when the users are of different genders. For this reason, there has been a demand for technology that can assign elevators in a way that is easy for each user to use, taking into account the degree of intimacy between the users.

The present invention has been made in consideration of the above circumstances, and aims to provide an elevator group management device and elevator group management method that can perform allocation processing taking into account the intimacy with other users when allocating an elevator to be used from among multiple elevators to an elevator user.

According to an embodiment for achieving the above object, when an elevator group control device acquires attribute information of a user who uses one of a plurality of elevators, it determines an elevator to be assigned to the user, and stores the acquired attribute information and the identification information of the elevator for which the assignment has been determined as assignment information until the car of the elevator for which the assignment has been determined departs from the floor. When the elevator group control device acquires attribute information of a second user while storing the assignment information of a first user, it calculates the intimacy between the users based on the attribute information of the first and second users, and determines an elevator to be assigned to the second user based on the calculated intimacy.

Below, as one embodiment of the present invention, we will explain the process performed by an elevator group management device that manages a group of multiple elevators to assign elevators to be used by users based on the intimacy between the users.

Configuration of an elevator system using an elevator group control device according to an embodiment
1 is an overall view showing the configuration of an elevator system 1 using an elevator group control device (hereinafter, referred to as the "group control device") according to one embodiment. The elevator system 1 includes a first elevator 10, a second elevator 20, and a third elevator 30 installed in a building, a hall device 40 installed in an elevator hall 2 on a predetermined floor in the building, for example, the first floor where the entrance is located, and a group control device 50. In this embodiment, a case where the elevator system 1 includes three elevators will be described, but the number is not limited to this number and may be two or four or more.

The first elevator 10 has a hoist 11 set in the hoistway 3, a rope 12 hung from the hoist 11, a car 13 suspended from one end of the rope 12, a first control panel 14, and a tail cord 15 connecting the car 13 and the first control panel 14.

The car 13 has a car door 131 and a load detection device 132. The load detection device 132 detects the amount of load applied to the floor surface of the car 13. The first control panel 14 controls the equipment in the first elevator 10, such as the hoist 11, based on information obtained from the group management device 50. The first control panel 14 also obtains information on the operation status of the first elevator 10 and the amount of load applied to the car 13 from the load detection device 132 via the tail code 15 at predetermined time intervals, and transmits this information to the group management device 50.

The second elevator 20 and the third elevator 30 have the same configuration as the first elevator 10, so detailed explanations will be omitted.

The hall device 40 has a reading unit 41, a notification unit 42, and a gate unit 43. The reading unit 41 reads the attribute information of a user using any of the first elevator 10, the second elevator 20, or the third elevator 30 from a medium that holds the attribute information of the user, such as an IC card or a mobile terminal, using short-range wireless communication or the like, and transmits the user attribute information to the group management device 50. The user's IC card or mobile terminal may be configured using an RFID tag that holds the user's attribute information, and the reading unit 41 may be configured as a tag reader that reads the RFID tag, so that the reading unit 41 reads the user's attribute information.

The notification unit 42 is composed of, for example, a display device, and outputs the elevator identification information assigned to the user by the group management device 50 based on the user's attribute information read by the reading unit 41, and notifies the user.

The gate unit 43 has a door (not shown) that opens and closes to restrict the entry of users into the elevator hall 2. The gate unit 43 maintains the door closed as an initial state, and when the group management device 50 authenticates that the user is a user who can use the first elevator 10, the second elevator 20, or the third elevator 30 based on the attribute information of the user read by the reading unit 41, the gate unit 43 temporarily opens the door.

The group management device 50 has a memory unit 51 and a CPU 52. The memory unit 51 has an elevator information memory unit 511, a user information memory unit 512, an allocation information memory unit 513, and a time zone information memory unit 514.

The elevator information storage unit 511 stores elevator information such as the installation location information of the first elevator 10, the second elevator 20, and the third elevator 30, the distance information from the hall device 40 to each of the first elevator 10, the second elevator 20, and the third elevator 30, and the time it takes for a user to walk from the hall device 40 to each of the first elevator 10, the second elevator 20, and the third elevator 30.

The user information storage unit 512 stores the identification information of users who are pre-set as users who can use the first elevator 10, the second elevator 20, or the third elevator 30.

The allocation information storage unit 513 stores allocation information generated by the CPU 52 as described below, linking attribute information of a user who performed a hall call operation at the hall device 40 with identification information of an elevator that has been determined to be allocated to this user, until the car of the determined elevator departs from the floor where the hall call operation was performed.

The time period information storage unit 514 stores information about time periods when the first elevator 10, the second elevator 20, or the third elevator 30 is likely to be used by multiple users whose intimacy level is equal to or greater than a predetermined threshold.

The CPU 52 has an operation control unit 521, a user information acquisition unit 522, an authentication unit 523, an allocation determination unit 524, and an output unit 525.

The operation control unit 521 controls the first elevator 10, the second elevator 20, and the third elevator 30 based on the operation status information of the first elevator 10 acquired from the first control panel 14, the operation status information of the second elevator 20 acquired from the second control panel 24, the operation status information of the third elevator 30 acquired from the third control panel 34, and the identification information of the elevators assigned to users by the allocation determination unit 524 as described below.

The user information acquisition unit 522 acquires user attribute information transmitted from the hall device 40. If the attribute information acquired by the user information acquisition unit 522 is included in the identification information stored in the user information storage unit 512, the authentication unit 523 authenticates the user corresponding to this attribute information as a user who can use the first elevator 10, the second elevator 20, and the third elevator 30.

The allocation determination unit 524 determines which elevator to allocate to the user authenticated by the authentication unit 523 from among the first elevator 10, the second elevator 20, and the third elevator 30. The allocation determination unit 524 generates allocation information that links attribute information of the authenticated user with identification information of the elevator determined to be allocated to this user, and stores the allocation information in the allocation information storage unit 513.

The output unit 525 outputs the authentication result by the authentication unit 523 and the identification information of the elevator whose allocation has been determined by the allocation determination unit 524 to the hall device 40.

Operation of an Elevator System According to an Embodiment
The operation of the elevator system 1 according to this embodiment will be described. In this embodiment, the user information storage unit 512 stores in advance the identification information of the first user X1 and the second user X2 as users who can use the first elevator 10, the second elevator 20, and the third elevator 30.

The operation control unit 521 also acquires operation status information of the first elevator 10 and the load weight of the car 13 from the first control panel 14 at predetermined time intervals, acquires operation status information of the second elevator 20 and the load weight of the car 23 from the second control panel 24 at predetermined time intervals, and acquires operation status information of the third elevator 30 and the load weight of the car 33 from the third control panel 34 at predetermined time intervals.

In addition, after car 13, 23, or 33 lands on the first floor and opens its doors, the operation control unit 521 calculates the time when the doors of the open car will close and depart next. For example, the operation control unit 521 calculates the time when the doors of the car will close next and depart (hereinafter referred to as the departure time) as the time when a predetermined time has elapsed since the boarding time of the first user to board car 13, 23, or 33.

When a first user X1, who uses either the first elevator 10, the second elevator 20, or the third elevator 30 from the first floor, holds the user's IC card Y1 over the reading unit 41 of the hall device 40 to enter the elevator hall 2 and make a hall call, the reading unit 41 reads the attribute information of the first user X1 stored on the IC card Y1 using short-range wireless communication or the like. The attribute information of the first user X1 includes, for example, the identification information of the first user X1, the name of the organization to which the user belongs, gender, age, destination floor information, etc. The reading unit 41 transmits the read attribute information of the first user X1 to the group management device 50.

Figure 2 is a flowchart showing the processing that the group management device 50 executes when it acquires user attribute information from the hall device 40.

In the group management device 50, the user information acquisition unit 522 of the CPU 52 acquires the attribute information of the first user X1 transmitted from the hall device 40 ("YES" in S1). When the user information acquisition unit 522 acquires the attribute information of the first user X1, the authentication unit 523 determines, based on the information stored in the user information storage unit 512, whether the first user X1 is a user who has been preset as a user who can use the first elevator 10, the second elevator 20, or the third elevator 30.

In this case, since the identification information of the first user X1 is stored in the user information storage unit 512, the authentication unit 523 authenticates that the first user X1 is a user who can use the first elevator 10, the second elevator 20, or the third elevator 30 ("YES" in S2).

When the authentication unit 523 authenticates that the first user X1 is a user who can use the first elevator 10, the second elevator 20, or the third elevator 30, the allocation determination unit 524 executes an allocation determination process to determine which elevator to allocate to the first user X1 for use from among the first elevator 10, the second elevator 20, and the third elevator 30 (S3).

Figure 3 is a flowchart showing the allocation determination process executed by the allocation determination unit 524. The allocation determination unit 524 first determines whether there is any allocation information stored in the allocation information storage unit 513, that is, whether there is an elevator that has been assigned to any user and whose car is in a pre-departure state from the departure floor corresponding to this assignment (S31).

Here, the allocation determination unit 524 determines that there is no allocation information stored in the allocation information storage unit 513 ("NO" in S31), and performs normal allocation determination processing for the first user X1 (S32). In the normal allocation determination processing, for example, the elevator to be assigned to the first user X1 is determined according to the operating status of the first elevator 10, the second elevator 20, and the third elevator 30, the congestion status of the cars 13, 23, and 33, the destination floor of the first user X1, etc., so that the elevators 10, 20, and 30 can operate efficiently while allowing the first user X1 to arrive at the destination floor as quickly as possible.

The allocation determination unit 524 determines to allocate, for example, the first elevator 10 to the first user X1, links the attribute information of the first user X1 with the identification information of the first elevator 10, and stores the linked information as allocation information in the allocation information storage unit 513. This ends the allocation determination process for the first user X1.

When the allocation determination process for the first user X1 is completed, returning to FIG. 2, the output unit 525 outputs the authentication result by the authentication unit 523 and information on the assigned elevator "first elevator 10" to the hall device 40 (S4). In the hall device 40, the door of the gate unit 43 is temporarily opened in response to the authentication result obtained from the group management device 50, and information on the assigned elevator "first elevator 10" is output from the notification unit 42.

The first user X1 recognizes the information about the assigned elevator output from the notification unit 42, enters the elevator hall 2 through the open gate unit 43, and gets into the car 13 of the first elevator 10.

After that, before the departure of the first elevator 10, the second user X2 holds the IC card Y2, which is a medium that holds the user's attribute information, over the reading unit 41 of the hall device 40, and the reading unit 41 reads the attribute information of the second user X2 and transmits it to the group management device 50.

In the group management device 50, the user information acquisition unit 522 acquires the attribute information of the second user X2 transmitted from the hall device 40 ("YES" in S1), and the authentication unit 523 authenticates that the second user X2 is a user who can use the first elevator 10, the second elevator 20, or the third elevator 30 ("YES" in S2).

When the authentication unit 523 authenticates that the second user X2 is a user who can use the first elevator 10, the second elevator 20, or the third elevator 30, the allocation determination unit 524 executes an allocation determination process to determine which elevator to allocate to the second user X2 (S3).

The allocation determination unit 524 first determines whether there is any allocation information stored in the allocation information storage unit 513 (S31). Here, the allocation information storage unit 513 stores allocation information that allocates the first elevator 10 to the first user X1, and the allocation determination unit 524 determines that there is any stored allocation information ("YES" in S31).

Next, the allocation determination unit 524 determines, based on the stored allocation information, whether there is any elevator among the assigned elevators whose car departure time is longer than the time it takes for the second user X2 to board (S33).

Specifically, the allocation determination unit 524 first calculates the time from the current time to the next departure time of the car 13 calculated by the operation control unit 521. The allocation determination unit 524 also calculates the time from when the second user X2 starts moving from the hall device 40 to when he/she boards the car 13 of the first elevator 10 corresponding to the allocation information stored in the allocation information storage unit 513, based on the information stored in the elevator information storage unit 511. The allocation determination unit 524 then compares the calculated time until the next departure time of the car 13 with the time until when the second user X2 boards the car 13.

Here, the allocation determination unit 524 determines that the calculated time until the next departure time of the car 13 is longer than the time it takes for the second user X2 to board the car 13. In other words, the allocation determination unit 524 determines that, among the assigned elevators, the first elevator 10 is an elevator whose time until the departure time of the car is longer than the time it takes for the second user X2 to board ("YES" in S33).

In this case, the assigned elevator is the first elevator 10, but if multiple elevators are assigned, it is determined for each of these elevators whether the time until the car's departure time is longer than the time it takes for the second user X2 to board.

When the allocation determination unit 524 determines that there is a first elevator 10 among the assigned elevators whose car departure time is longer than the time it takes for the second user X2 to board, it selects this first elevator 10 as a candidate for allocation to the second user X2 who has performed the hall call operation this time (S34).

Next, the allocation determination unit 524 calculates the degree of intimacy between the first user X1 and the second user X2 based on the attribute information of the second user X2 acquired by the user information acquisition unit 522 and the attribute information of the first user X1 to which the first elevator 10, which is an allocation candidate, is assigned, which is stored in the allocation information storage unit 513.

The allocation determination unit 524 calculates the degree of intimacy between users based on the evaluation value of the intimacy for each preset attribute condition, for example, the degree of intimacy between users who belong to the same organization is 2.1, the degree of intimacy between family members is 2.5, and the degree of intimacy between users who belong to different organizations in the same industry is 0.5. The higher the value of this intimacy, the higher the degree of intimacy.

When the calculated intimacy between the first user X1 and the second user X2 is equal to or less than a predetermined first threshold ("YES" in S35), the allocation determination unit 524 determines to allocate an elevator other than the first elevator 10, which is an allocation candidate, for example, the second elevator 20, to the second user X2 (S36).

The first threshold is a threshold for determining whether it is better for two users who are the subject of the judgment process to ride in separate elevators so as not to ride in the same elevator. The allocation determination unit 524 assigns different elevators to two users whose calculated intimacy level is equal to or less than the first threshold.

In addition, if the calculated intimacy between the first user X1 and the second user X2 exceeds a predetermined first threshold value ("NO" in S35) and is equal to or greater than the second threshold value ("YES" in S37), the allocation determination unit 524 determines whether the car 13 of the first elevator 10, which is an allocation candidate acquired by the operation control unit 521, is full or not (S38).

When the allocation determination unit 524 determines that the intimacy between the first user X1 and the second user X2 is equal to or greater than the second threshold value and that the car 13 of the first elevator 10 is not full ("NO" in S38), it determines to allocate the first elevator 10, which is an allocation candidate, to the second user X2 (S39).

The second threshold is a threshold for determining whether it is better for the two users being the subject of the judgment process to ride in the same elevator, and the allocation determination unit 524 assigns the same elevator to two users whose intimacy level is calculated to be equal to or greater than the second threshold if the two users can ride in the same elevator at the same time.

If it is determined in step S33 that there is no assigned elevator whose car departure time is longer than the time it takes for the second user X2 to board ("NO" in S33), if the intimacy between the first user X1 and the second user X2 calculated in step S37 exceeds the first threshold value and is less than the second threshold value ("NO" in S37), or if it is determined in step S38 that the car 13 is full ("YES" in S38), the process proceeds to step S32 and a normal assignment determination process is performed for the second user X2 (S32).

When the allocation determination unit 524 determines the elevator to be allocated to the second user X2 in step S36, S39, or S32, the attribute information of the second user X2 is linked to the identification information of the determined elevator, and the linked information is stored as allocation information in the allocation information storage unit 513. This ends the allocation determination process for the second user X2.

When the allocation determination process for the second user X2 is completed, the output unit 525 outputs the authentication result by the authentication unit 523 and the assigned car information to the hall device 40 (S4). In the hall device 40, the door of the gate unit 43 is opened in response to the authentication result obtained from the group management device 50, and the assigned car information is output from the notification unit 42.

The second user X2 recognizes the information about the assigned elevator output from the notification unit 42, enters the elevator hall 2 through the open gate unit 43, and gets into the elevator car of the recognized assigned elevator.

When the car 13 in which the first user X1 has boarded departs from the first floor through the above-mentioned process, the allocation determination unit 524 deletes the allocation information related to the first user X1 stored in the allocation information storage unit 513. In addition, if the car in which the second user X2 has boarded is other than the car 13, when the car in which the second user X2 has boarded departs from the first floor, the allocation determination unit 524 deletes the allocation information related to the second user X2 stored in the allocation information storage unit 513.

According to the above embodiment, the group management device can assign an elevator that is easy to use from among multiple elevators to a user who has specified a destination floor at a landing and performed a landing call operation, depending on the user's intimacy with other users. Specifically, different elevators are assigned to multiple users who have a low level of intimacy and should share the elevator, and the same elevator is assigned to multiple users who have a high level of intimacy and who should preferably ride together in the elevator. By performing the assignment process in this way, users can use the elevators with peace of mind.

In the above-described embodiment, when performing the allocation determination process for the second user X2 whose intimacy with the first user X1 to whom the first elevator 10 has already been assigned is higher than the second threshold, if the first elevator 10 is full and cannot be assigned to the second user X2, the allocation determination unit 524 may change the allocation of the first user X1 to another elevator, for example the second elevator 20, and may also allocate the second elevator 20 after this change to the second user X2.

In this case, the output unit 525 of the group management device 50 may output information that the allocation for the second user X2 has been changed to the second elevator 20 to the hall device 40, and the hall device 40 may notify the first user X1 by transmitting the information to a mobile device carried by the first user X1, for example, by using short-range wireless communication.

By performing the allocation change process in this manner, it is possible to perform a highly convenient allocation determination process for the first user X1 and the second user X2, who have a high degree of intimacy.

In the above-described embodiment, if, in step S33, there is no assigned elevator whose time until the car departs is longer than the time it takes for the second user X2 to board ("NO" in S33), but there is an elevator whose time until the car departs is shorter than the time it takes for the second user X2 to board, and the difference between the time until the car departs and the time it takes for the second user X2 to board is less than a predetermined value, for example, within 5 seconds, then this elevator may be used as an assignment candidate and the processing from step S34 onwards may be executed.

In this case, if the intimacy between the first user X1 and the second user X2 is equal to or greater than the second threshold value and the elevator that was selected as an allocation candidate as described above is assigned to the second user X2 in step S39, the assignment determination unit 524 sends an instruction to the operation control unit 521 to delay the departure time of the assigned elevator by a predetermined time. By performing processing in this manner, the elevator can be operated efficiently while allowing users with high intimacy to ride in the same car as much as possible.

In the above-described embodiment, during a time period when the probability of use of the first elevator 10, the second elevator 20, and the third elevator 30 by multiple users is high and the degree of intimacy between the users calculated based on the attribute information of the users is equal to or greater than a predetermined third threshold, the allocation determination unit 524 may, upon acquiring attribute information of one of the multiple users, predict that attribute information of the other users will be acquired within a predetermined time period, and determine an elevator to be assigned as a target for use by the user whose attribute information has been acquired based on the predicted information. This third threshold is a threshold for determining whether the multiple users being the subject of the determination process are moving toward the same destination floor during the same time period, for example, depending on whether they belong to the same organization.

In this case, for example, the allocation determination unit 524 uses machine learning to learn the contents of the allocation determination process executed in a predetermined period of time in the past to calculate a time period during which the first elevator 10, the second elevator 20, and the third elevator 30 are likely to be used by multiple users whose intimacy is equal to or greater than a third threshold, and stores the information on the calculated time period in advance in the time period information storage unit 514. Then, based on the information stored in the time period information storage unit 514, when the allocation determination unit 524 detects that attribute information of one of the multiple users has been acquired from the hall device 40 at a time corresponding to this time period, it determines that another user who has a high intimacy with this user is likely to subsequently use the first elevator 10, the second elevator 20, or the third elevator 30, and allocates an elevator with as many vacant cars as possible.

By performing the allocation decision process in this manner, elevators 10, 20, and 30 in elevator system 1 can be operated more efficiently.

when the user information acquisition unit acquires new attribute information of a second user while the allocation information storage unit is storing allocation information of a first user, the allocation determination unit calculates a degree of intimacy between the first user and the second user based on the acquired attribute information of the second user and the attribute information in the allocation information of the first user stored in the allocation information storage unit, and determines an elevator to be allocated to the second user based on the calculated degree of intimacy;
When the user information acquisition unit acquires attribute information of one of the multiple users at a time corresponding to the time period stored in the time period information storage unit, the elevator group management device predicts that attribute information of another user among the multiple users will be acquired within a specified time period, and determines, based on the predicted information, an elevator to be assigned as a target for use by the user whose attribute information has been acquired . 2. The elevator group management device according to claim 1, wherein the allocation determination unit assigns the elevator assigned to be used by the first user to be used by the second user when the calculated intimacy between the first user and the second user is equal to or greater than the second threshold value and the elevator assigned to be used by the first user is not full. Group management of multiple elevators,
a user information acquisition unit that acquires attribute information of a user who uses any one of the plurality of elevators from a predetermined floor;
an allocation determination unit that, when the user information acquisition unit acquires the attribute information, determines an elevator to be allocated to be used by the user from among the plurality of elevators;
an output unit that outputs identification information of the elevator whose allocation has been determined by the allocation determination unit;
an allocation information storage unit that stores the attribute information acquired by the user information acquisition unit and the identification information of the elevator for which the allocation has been determined by the allocation determination unit as allocation information of the user until the car of the elevator for which the allocation has been determined departs from the floor,
when the allocation information storage unit is storing allocation information of a first user and the user information acquisition unit newly acquires attribute information of a second user, calculates a degree of intimacy between the first user and the second user based on the acquired attribute information of the second user and the attribute information in the allocation information of the first user stored in the allocation information storage unit;
When the calculated intimacy between the first user and the second user is equal to or less than a first threshold, an elevator to be assigned to the second user is determined so that the elevators assigned to the first user and the second user are different from each other;
When the calculated intimacy between the first user and the second user is equal to or greater than a second threshold value that is higher than the first threshold value, determining an elevator to be assigned to the second user so that the elevators assigned to the first user and the second user are the same;
An elevator group management method, in which, when the calculated intimacy between the first user and the second user is equal to or greater than the second threshold value and an elevator already assigned for use by the first user is full, the assignment of the elevator to be used by the first user is changed to another elevator, and the changed elevator is assigned for use by the second user .
