Disclosure of Invention

Problems to be solved by the invention

However, in the conventional technique, the operating efficiency of the elevator may be reduced due to congestion in the waiting hall. For example, when there are a large number of users who use a low-rise building as a destination building, even if a bidirectional elevator group is allocated to the low-rise building, the low-rise building is still crowded, and the operation efficiency of the elevator is lowered due to a time loss when the user takes the elevator car.

Means for solving the problems

An operation method of an elevator system according to an embodiment includes an allocation step, a congestion estimation step, and a determination step. In the assigning step, any one of a 1 st car, a 2 nd car, and a 3 rd car is assigned for a hall call, the 1 st car being capable of stopping at a 1 st floor, the 2 nd car being capable of stopping at a 2 nd floor including floors different from the 1 st floor, and the 3 rd car being capable of stopping at the 1 st floor and the 2 nd floor, and having a 1 st door capable of opening and closing in a direction of a 1 st hall common to the 1 st car and a 2 nd door capable of opening and closing in a direction of a 2 nd hall common to the 2 nd car. In the congestion estimation step, the congestion status of each of the 1 st lobby and the 2 nd lobby is estimated. In the determining step, the door to be opened or closed of the 1 st door and the 2 nd door is determined based on the estimated congestion status.

Detailed Description

Hereinafter, an elevator system and an operation method of the elevator system according to the embodiments will be described in detail with reference to the drawings. The components in this embodiment include components that can be replaced and easily replaced by those skilled in the art, or substantially the same components, and the present invention is not limited to the following embodiments.

The elevator system according to the embodiment is a system that can be installed in a high-rise building, for example. This system is an elevator system including, for example, an elevator group for a low floor, an elevator group for a high floor, and a bidirectional elevator group, and performs operation management (group management) of cars of the elevators according to a use floor, thereby constituting a so-called "elevator group".

(embodiment 1)

Fig. 1 is a schematic diagram showing an example of the configuration of an elevator group of an elevator system 1 according to embodiment 1. As shown in fig. 1, an elevator system 1 of the present embodiment includes

elevator groups

3a, 3b, 3c. The elevator group 3a is an elevator group including a plurality of lower elevators 2 a. Elevator group 3b is an elevator group comprising a plurality of bi-directional elevators 2b. The elevator group 3c is an elevator group comprising a plurality of high-rise elevators 2c. The number of elevators included in each elevator group is not limited to 4, and may be 1 to 3, or 5 or more.

The low-rise elevator 2a is an elevator including a car (1 st car) that can stop at a floor (1 st floor) including a predetermined common stop floor and a low floor. The high-rise elevator 2c is an elevator including a car (2 nd car) that can stop at a floor (2 nd floor) including a common stop floor and a high-rise floor. For example, in the case of a building constructed with 20 floors above the ground, the common berthing floor is 1 floor, the lower floors are 2 floors to 10 floors, and the upper floors are 11 floors to 20 floors. The landing layer is not limited to these. For example, a common stop layer other than the 1 st layer may be further provided.

In the above example, the hoistway need not be installed at 11 floors or more in the elevator group 3 a. In addition, regarding the elevator group 3c, it is not necessary to provide a waiting hall at 2 to 10 floors. This can reduce the installation cost when a plurality of elevators are operated. In addition, the space that does not require part of the hoistway or the hall can be used as a space for other purposes, and this can contribute to effective use of the space of the building.

The bidirectional elevator 2b is an elevator including a car (3 rd car) that can stop at a common stop floor, a lower floor, and an upper floor. The car of the bidirectional elevator 2b is provided with a door 4b-1 (door 1) and a door 4b-2 (door 2) as entrances and exits. The door 4b-1 is a door that can be opened and closed in the direction of the standby area 8, which is a lobby (1 st lobby) common to the cars of the lower-floor elevators 2 a. The door 4b-2 is a door that can be opened and closed in the direction of the standby area 9, which is a waiting hall (2 nd waiting hall) common to the cars of the high-rise elevator 2c.

The standby zone 8 is disposed, for example, between the elevator group 3a and the elevator group 3b facing each other. The user using the lower floor is on standby in the standby area 8 in principle. The standby zone 9 is disposed, for example, between the mutually opposing elevator group 3b and elevator group 3c. The user using the upper floor principally waits in the waiting area 9.

The doors 4b-1 and 4b-2 are not limited to the configuration in which they open in opposite directions (directions that differ by 180 degrees) when viewed from the inside of the car, and may open in orthogonal directions (directions that differ by 90 degrees), for example.

Fig. 2 is a schematic diagram showing an example of the system configuration of the elevator system 1 according to the present embodiment. As shown in fig. 2, the elevator system 1 includes a group management control device 100, a plurality of

elevator control devices

10a, 10b, and 10c, a destination hall registration device 210, a hall guide device 220, a low-rise elevator 2a, a bidirectional elevator 2b, and a high-rise elevator 2c.

The destination hall registration device 210 is a device for a user to register a destination hall. The hall guidance device 220 is a device for guiding (notifying) the user of the hall of the elevator allocated by the group management control device 100. The destination hall registration device 210 and the hall guide device 220 are provided at, for example, a hall of each floor of an elevator and an entrance of a building.

The destination hall registration device 210 can be configured by, for example, an input device having numeric keys for registering a destination hall. The destination hall registration device 210 is not limited to this, and may be a type common to a touch panel type input device and a security gate type input device, for example. In the case of a security gate type input device, a destination landing of a registered floor (for example, a floor such as an office of the user) may be input by presentation of identification or a pass. In addition, as the input device, a biometric authentication system, a voice input system, or the like may be used.

The hall guidance device 220 can be implemented as a display device including, for example, an LED (light emitting diode), an LCD (liquid crystal display), an OELD (organic electroluminescent display), and the like. The hall guidance device 220 is not limited to this, and may include, for example, a sound output device (such as a speaker) that outputs guidance information by sound in addition to the display device, or a sound output device (such as a speaker) that outputs guidance information by sound without a display device. The destination hall registration device 210 and the hall guide device 220 may be configured as 1 device.

The group management control device 100 allocates an elevator (elevator number) in which a user is to take among a plurality of elevators, in accordance with a hall call including a destination hall designated by the user. The group management control device 100 determines an elevator to be allocated, for example, in consideration of a target hall specified by a user using the target hall registration device 210 and operation information indicating the operation state of each elevator. As described above, the elevator System 1 according to the present embodiment can be realized as a group management elevator System called a DCS (Destination Control System) in which a user can specify a Destination hall in a hall.

The group management control device 100 is connected to the

elevator control devices

10a, 10b, and 10c via communication lines, and transmits and receives data to and from the elevator control devices. The group management control device 100 is connected to the destination hall registration device 210 and the hall guidance device 220 via a communication line, and transmits and receives data to and from the devices. Each communication line may be wired or wireless.

The

elevator control devices

10a, 10b, and 10c control the raising and lowering of a lower-floor elevator 2a belonging to the elevator group 3a, a bidirectional elevator 2b belonging to the elevator group 3b, and a higher-floor elevator 2c belonging to the elevator group 3c, respectively. In fig. 2, for convenience of explanation, only 1 elevator in each elevator group is shown. The

elevator control devices

10a, 10b, and 10c are installed in, for example, a hoistway and a machine room of each elevator.

When the target landing registration operation is performed by the target landing registration device 210 and the group management control device 100 determines an elevator to be operated, the

elevator control devices

10a, 10b, and 10c determine the target landing, the moving direction (ascending/descending direction), the moving speed, and the like of the elevator (assigned car), and operate the assigned car.

The group management control device 100 and the

elevator control devices

10a, 10b, and 10c may be configured by a microcomputer including a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and the like.

Next, the details of the functions of the group management control device 100 will be described. The group management control device 100 includes an assignment unit 101, a congestion estimation unit 102, a determination unit 103, and a notification control unit 104.

The allocation unit 101 refers to the information indicating the target hall transmitted from the target hall registration device 210 and the operation information transmitted from the

elevator control devices

10a, 10b, and 10c, and allocates the best elevator to the hall call including the target hall specified by the user.

The congestion estimation unit 102 estimates the congestion status of each of the

standby areas

8 and 9. For example, the congestion estimation unit 102 compares the number of registered items of each destination hall using each standby area with a threshold value set for each standby area as a value of the number of registered items that may be congested, and estimates that the standby area is congested when the number of registered items is greater than the threshold value.

When the assignment unit 101 assigns the bidirectional elevator 2b, the determination unit 103 determines a door to be opened or closed among the doors of the bidirectional elevator 2b based on the congestion status estimated by the congestion estimation unit 102. For example, when it is estimated that the standby area 8 is crowded, the determination unit 103 determines the door 4b-2 that can be opened and closed in the direction of the standby area 9 as the door to be opened and closed. In addition, when it is estimated that the standby area 9 is crowded, the determination unit 103 determines the door 4b-1 that can be opened and closed in the direction of the standby area 8 as the door to be opened and closed.

In the present embodiment, even when the bidirectional elevator 2b is allocated to a hall call in which a high-rise building is a destination hall, if the standby area 9 common to the high-rise elevator 2c is congested, the door 4b-1 openable in the direction of the standby area 8 is determined as the door to be opened and closed. Similarly, even when the bidirectional elevator 2b is allocated to a hall call in which the lower floor is the destination hall, if the standby area 8 common to the lower-floor elevator 2a is congested, the door 4b-2 that can be opened and closed in the direction of the standby area 9 is determined as the door to be opened and closed.

With such a configuration, even when there are a large number of users who use a low-rise (high-rise) landing as a destination landing, for example, a bidirectional elevator group is allocated to the low-rise (high-rise) landing, it is possible to avoid congestion in a waiting hall for the low-rise (high-rise) landing. As a result, a decrease in the operation efficiency of the elevator can be avoided.

Further, for example, when the bidirectional elevator 2b is allocated to a hall call in which the upper floor is the destination hall and the waiting area 9 common to the upper floor elevator 2c is not congested, the determination unit 103 may determine the door 4b-2 openable and closable in the direction of the waiting area 9 as the door to be opened and closed. Similarly, for example, when the bidirectional elevator 2b is allocated to a hall call in which the lower floor is the destination hall and the waiting area 8 common to the lower-floor elevator 2a is not congested, the determination unit 103 may determine the door 4b-1 openable and closable in the direction of the waiting area 8 as the door to be opened and closed.

In the case where both the standby area 8 and the standby area 9 are congested, the determination unit 103 may determine, as the door to be opened and closed, a door that can be opened and closed in the direction of the standby area corresponding to the destination landing, or may determine, as the door to be opened and closed, a door that can be opened and closed in the direction of the standby area with relatively little congestion.

The notification control unit 104 controls notification of information to the

elevator control devices

10a, 10b, and 10c, the hall guide device 220, and the like. For example, the notification control unit 104 notifies the elevator control device corresponding to the elevator allocated by the allocation unit 101 of the destination hall registration (hall call) in response to the user designation. The notification control unit 104 notifies the elevator control device 10b that controls the bidirectional elevator 2b of the door determined to be opened and closed by the determination unit 103.

The notification control unit 104 controls the hall guidance device 220 to notify the user who operates the hall call of the hall corresponding to the door determined to be opened and closed by the determination unit 103. Further, the notification control section 104 may control the

elevator control devices

10a, 10b, and 10c to notify the user of the bidirectional elevator 2b of the destination hall of the bidirectional elevator 2b. For example, the notification control section 104 may notify the user waiting in the

standby zone

8 or 9 of the destination hall of the bidirectional elevator 2b using an output device such as a display device or an audio output device provided in each elevator or in each standby zone. Thus, the user can be prevented from getting on the floor, and the operation efficiency of the elevator can be further improved.

Next, an example of an operation method of the elevator system 1 configured as described above will be described with reference to fig. 3. Fig. 3 is a flowchart showing an example of an operation method of the elevator system 1 according to embodiment 1.

The allocation unit 101 determines whether or not the destination hall registration device 210 registers the destination hall (step S101). When the destination hall is not registered (no in step S101), the process is repeated until the destination hall is registered. When a destination hall is registered (yes in step S101), the assignment unit 101 determines an elevator to be assigned based on the registered destination hall and the operation information of each elevator and the like (step S102).

The notification control unit 104 notifies the assigned elevator control device, out of the

elevator control devices

10a, 10b, and 10c, that the assigned elevator is controlled (step S103).

The assigning unit 101 determines whether or not the bidirectional elevator 2b is assigned (step S104). When the bidirectional elevator 2b is allocated (yes in step S104), the congestion estimation unit 102 estimates whether or not the standby zone 8 at the lower floor or the standby zone 9 at the higher floor is congested (step S105).

When the standby area 8 or the standby area 9 is congested (yes in step S105), the determination unit 103 determines, as a door to be opened or closed, a door that can be opened or closed in the direction of an uncongested standby area, from among the doors 4b-1 and 4b-2 (step S106).

The notification control unit 104 controls the hall guidance device 220 to notify the user of information indicating that the waiting area corresponding to the determined door is the hall and information indicating the determined elevator (car) (step S107). The notification control unit 104 also notifies the elevator control device 10b that controls the bidirectional elevator 2b of the information of the door determined to be opened and closed (step S108).

The elevator control device 10b that has received the notification controls the bidirectional elevator 2b to open and close the determined door. This allows the user to take the bidirectional elevator 2b from the guided lobby.

Further, the notification control section 104 controls the elevator control device 10b to notify the user of the bidirectional elevator 2b of the destination hall (step S109).

When it is determined in step S104 that the bidirectional elevator 2b is not allocated (no in step S104) and when it is determined in step S105 that the standby area 8 or the standby area 9 is not congested (no in step S105), the notification control section 104 controls the hall guidance device 220 to notify the user of information indicating that the standby area corresponding to the elevator allocated according to the destination hall is a hall and information indicating the allocated elevator (car) (step S110).

After step S109 and step S110, the elevator control device that controls the allocated elevator among the

elevator control devices

10a, 10b, and 10c controls the operation of the elevator in accordance with the registered destination hall (step S111).

As described above, in the elevator system 1 of the present embodiment, when the low-rise standby area or the high-rise standby area is congested and a bidirectional elevator is allocated, the user is guided to ride in the uncongested standby area, and the door to be opened and closed of the bidirectional elevator is determined. This can alleviate congestion in the elevator waiting hall and improve the operation efficiency of the elevator.

(embodiment 2)

The elevator system according to embodiment 2 further includes a function of estimating a congestion status at the present time from a past usage status of the elevator. Fig. 4 is a schematic diagram showing an example of a system configuration of an elevator system according to embodiment 2. As shown in fig. 4, the elevator system according to embodiment 2 includes a group management control device 100-2, a plurality of

elevator control devices

10a, 10b, and 10c, a destination hall registration device 210, a hall guide device 220, a lower-level elevator 2a, a bidirectional elevator 2b, and a higher-level elevator 2c.

In embodiment 2, the group management control device 100-2 is different from embodiment 1 in that it includes a storage unit 121-2, the function of a congestion estimation unit 102-2, and the function of a determination unit 103-2. The other components are the same as those in fig. 2 showing the system configuration of embodiment 1, and therefore the same reference numerals are given thereto, and the description thereof is omitted.

The storage unit 121-2 stores a use status database indicating the use status of the elevator in the past. The usage situation database stores information indicating the congestion situation, such as the number of users (the number of registered users at the destination hall), for each time slot and each standby area, for example. The time period may be represented not only by time (time, time division, etc.) but also by information such as the week, month, and season. The storage unit 121-2 may be configured by a storage medium such as a ROM, a RAM, an HDD (Hard Disk Drive), and an SSD (Solid State Drive).

The congestion estimating unit 102-2 further has a function of estimating the current congestion state by referring to the use state database stored in the storage unit 121-2. For example, the congestion estimation unit 102-2 determines whether or not the current time is included in the congestion time zone determined in the usage status database. The congestion time period is, for example, a range of times determined as the time when the number of users exceeds a predetermined threshold. The congestion time period is, for example, a work time period, a rest time period, and the like, but is not limited thereto.

When the assignment unit 101 assigns the bidirectional elevator 2b and the congestion estimation unit 102-2 determines that the current time is included in the congestion time zone, the determination unit 103-2 determines, as the door to be opened or closed of the bidirectional elevator 2b, a door in the direction of a hall (standby area) identified as a hall that is not congested in the congestion time zone.

Next, an example of an operation method of the elevator system according to embodiment 2 configured as described above will be described with reference to fig. 5. Fig. 5 is a flowchart showing an example of an operation method of the elevator system according to embodiment 2.

Steps S201 to S204 are the same as steps S101 to S104 in fig. 3 showing the operation method of the elevator system according to embodiment 1, and therefore, the description thereof is omitted.

When the bidirectional elevator 2b is allocated (yes in step S204), the congestion estimation unit 102-2 determines whether or not the current time is included in a congestion time zone set in advance (step S205). If the current time is included in the preset congestion time zone (yes in step S205), the determination unit 103-2 determines the door that can be opened and closed in the direction of the uncongested standby zone in the congestion time zone as the door to be opened and closed of the bidirectional elevator 2b (step S207).

When the current time is not included in the preset congestion time period (no in step S205), the congestion estimation unit 102-2 estimates whether or not the standby area 8 of the lower hierarchy level or the standby area 9 of the higher hierarchy level is congested, as in step S105 of embodiment 1 (step S206).

The subsequent processes (step S208 to step S212) are the same as step S107 to step S111 in fig. 3 showing the operation method of the elevator system according to embodiment 1, and therefore, the description thereof is omitted.

The congestion estimation unit 102-2 may determine not only whether or not the current time is included in the preset congestion time zone, but also whether or not congestion actually occurs to the same extent or more as the preset congestion time zone. For example, when the current time is included in a preset congestion time zone, the congestion estimation unit 102-2 further determines whether or not the number of registered destination halls at the current time is equal to or greater than the number of registered destination halls stored in association with the congestion time zone. When the number of registered destination halls at the current time is equal to or greater than the number of registered stored numbers, the determination unit 103-2 determines, as the door of the bidirectional elevator 2b to be opened or closed, a door that can be opened or closed in the direction of the uncongested standby zone in the congestion time zone.

When the number of registered hall at the current time is smaller than the stored number of registered hall, the congestion estimation unit 102-2 may estimate whether or not the standby area 8 at the lower hierarchy level or the standby area 9 at the higher hierarchy level is congested, as in step S105 of embodiment 1.

The congestion estimation unit 102-2 may determine whether or not the current congestion status is the same as the congestion status in the preset congestion time zone. For example, the congestion estimation unit 102-2 may calculate a difference between the number of registered destination halls at the current time and the number of registered destination halls stored in association with the congestion time zone, and estimate that the waiting hall (waiting area) associated with the congestion time zone is congested when the difference is equal to or less than a threshold value.

As described above, in the present embodiment, when the congestion time zone is set in advance, the door that can be opened and closed in the direction of the standby area that is estimated not to be congested is determined as the door to be opened and closed with reference to the past congestion status, and the user is guided to the standby area. This makes it possible to further alleviate the congestion in the elevator hall and to further improve the operation efficiency of the elevator.

(modification example)

In the modification, a function of determining a door to be opened and closed of the bidirectional elevator based on a position (standing position) of a user in the bidirectional elevator is further added. Fig. 6 is a flowchart showing an example of an operation method of an elevator system according to a modification. Fig. 6 shows an example in which a modification is applied to embodiment 1. The same modification can be applied to embodiment 2.

In the present modification, the determination unit 103 determines a door to be opened or closed among the doors of the bidirectional elevator 2b, based on the position of the user in the bidirectional elevator 2b. The determination unit 103 determines, for example, a door at a position close to the user as a door to be opened or closed. With this configuration, the user can get off the car more smoothly.

The determination unit 103 may determine a door located far from the user as a door to be opened or closed. With such a configuration, when another user gets into the car of the bidirectional elevator 2b, the user who has already got into the car does not need to move within the car and temporarily get off the car.

The position of the user in the bidirectional elevator 2b can be obtained by, for example, analyzing an image obtained from an imaging device (such as a camera) provided in the car of the bidirectional elevator 2b. The determination unit 103 can obtain an image from an imaging device in the car via the elevator control device 10b, for example. The method of determining the position of the user is not limited to this.

Next, an example of an operation method of the elevator system according to the modification configured as above will be described with reference to fig. 6. Fig. 6 is a flowchart showing an example of an operation method of an elevator system according to a modification.

Steps S301 to S304 are the same as steps S101 to S104 in fig. 3 showing the operation method of the elevator system according to embodiment 1, and therefore, the description thereof is omitted.

When the bidirectional elevator 2b is allocated (yes in step S304), the determination unit 103 determines whether or not there is a user in the bidirectional elevator 2b (step S305). When there is a user in the bidirectional elevator 2b (yes in step S305), the determination unit 103 determines the door in the direction corresponding to the position of the user in the bidirectional elevator 2b as the door to be opened or closed (step S306).

When there is no user in the bidirectional elevator 2b (no in step S305), the congestion estimation unit 102 estimates whether or not the standby area 8 at the lower floor or the standby area 9 at the higher floor is congested, as in step S105 of embodiment 1 (step S307).

The subsequent processes (step S308 to step S313) are the same as step S106 to step S111 in fig. 3 showing the operation method of the elevator system according to embodiment 1, and therefore, the description thereof is omitted.

When the present modification is applied to embodiment 2, for example, after it is determined in step S305 that there is no user in the bidirectional elevator 2b, the determination in step S205 in fig. 5 may be executed.

Several embodiments of the present invention have been described above, but these embodiments are presented as examples and are not intended to limit the scope of the invention. These embodiments can be implemented in other various ways, and various omissions, substitutions, and changes can be made without departing from the spirit of the invention.
