Description

Embodiments of the present invention relate to an operating method of an elevator system.

Conventionally, an elevator system that manages the operation of a plurality of elevators is known. In high-rise buildings, there are cases where an elevator system that constitutes a so-called "elevator bank" is constructed, in which group management is performed by dividing the floors used, such as elevator groups for lower floors and elevator groups for higher floors. be. In addition, between the elevator group for the lower floors and the elevator group for the upper floors, a two-way elevator group that can be stopped on all floors with a door that can be opened and closed in two directions is provided, and the elevator group for the lower floors and the elevator group for the upper floors and the elevator group for the upper floors. A technique has been proposed in which the destination floor of the two-way elevator group is set to either the lower floor or the upper floor according to the congestion situation of the elevator group for the upper floor.

Japanese Unexamined Patent Publication No. 01-32179

However, in the prior art, the operating efficiency of the elevator may be lowered due to the congestion of the landing. For example, if there are many users whose destination floor is the lower floor, even if the two-way elevator group is assigned to the lower floor, the landing for the lower floor will be crowded and the elevator will be lost due to time loss when getting in the car. In some cases, the operating efficiency of the vehicle was reduced.

The operation method of the elevator system of the embodiment includes an allocation step, a congestion estimation step, and a determination step. The allocation step is a first car that can be stopped on the first floor, a second car that can be stopped on the second floor including a floor different from the first floor, and a first. The first door that can be stopped on the floor and the second floor and can be opened and closed in the direction of the first landing common to the first car and the second landing common to the second car One of a third rider with a second door that can be opened and closed in the direction is assigned to the landing call. The congestion estimation step estimates the congestion status of each of the first landing and the second landing. The determination step determines which of the first and second doors to open and close, depending on the estimated congestion situation. The congestion estimation step determines whether or not the current time is included in a predetermined congestion time zone. The determination step is determined as a door that opens and closes the door in the direction of the landing, which is defined as a landing that is not congested during the busy time, when the current time is included in the busy time zone, and the current time is included in the busy time zone. If not, the door to open / close is determined among the first door and the second door according to the estimated congestion situation.

FIG. 1 is a schematic view showing an example of the configuration of an elevator bank of the elevator system 1 of the first embodiment. As shown in FIG. 1, the elevator system 1 of the present embodiment includes elevator banks 3a, 3b, and 3c. The elevator bank 3a is an elevator bank including a plurality of lower floor elevators 2a. The elevator bank 3b is an elevator bank including a plurality of two-way elevators 2b. The elevator bank 3c is an elevator bank including a plurality of high-rise elevators 2c. The number of elevators included in each elevator bank is not limited to four, and may be one to three, or five or more.

The lower floor elevator 2a is an elevator provided with a car (first car) capable of stopping on a floor (first floor) including a predetermined common stop floor and lower floors. The high-rise elevator 2c is an elevator provided with a car (second car) that can be stopped on a floor (second floor) including a common stop floor and a high floor. For example, in the case of a 20-story building, the common stop floor is the 1st floor, the lower floors are the 2nd to 10th floors, and the upper floors are the 11th to 20th floors. The stop floors are not limited to these. For example, a common stop floor other than the first floor may be further set.

In the above example, for the elevator bank 3a, it is not necessary to provide a hoistway on the 11th floor or higher. In addition, for the elevator bank 3c, it is not necessary to provide a landing on the 2nd to 10th floors. This makes it possible to reduce the laying cost when operating a plurality of elevators. In addition, a part of the space that does not require a hoistway and a landing can be used as a space for another purpose, which can contribute to effective utilization of the space of the building.

The two-way elevator 2b is an elevator provided with a car (third car) capable of stopping on a common stop floor, a lower floor, and a higher floor. The car of the two-way elevator 2b is provided with a door 4b-1 (first door) and a door 4b-2 (second door) that serve as entrances and exits. The door 4b-1 is a door that can be opened and closed in the direction of the waiting area 8 which is a common landing (first landing) for the elevator 2a on the lower floor. The door 4b-2 is a door that can be opened and closed in the direction of the waiting area 9, which is a common landing (second landing) for the elevator 2c on the upper floor.

The standby area 8 is provided, for example, between the elevator banks 3a and the elevator banks 3b facing each other. As a general rule, users who use the lower floors stand by in the waiting area 8. The standby area 9 is provided, for example, between the elevator banks 3b and the elevator banks 3c facing each other. As a general rule, users who use the upper floors stand by in the waiting area 9.

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

FIG. 2 is a schematic diagram showing an example of the system configuration of the elevator system 1 of 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, 10c, a destination floor registration device 210, a landing guidance device 220, a lower floor elevator 2a, and the like. Includes a two-way elevator 2b and a higher floor elevator 2c.

The destination floor registration device 210 is a device for the user to register the destination floor. The landing guidance device 220 is a device for guiding (notifying) the user of the elevator landing assigned by the group management control device 100. The destination floor registration device 210 and the landing guidance device 220 are installed, for example, at the landing on each floor of the elevator, the entrance of the building, and the like.

The destination floor registration device 210 can be configured by, for example, an input device including a numeric keypad for registering the destination floor. The destination floor registration device 210 is not limited to this, and may be, for example, a type shared with a touch panel type input device and a security gate type input device. In the case of a security gate type input device, the destination floor of the registered floor (for example, the floor of one's own office) may be input by presenting an identification card, a pass card, or the like. In addition, a biometric authentication system, a voice input system, or the like may be used as the input device.

The landing guidance device 220 can be realized as a display device including, for example, an LED (light emitting diode), an LCD (liquid crystal display), and an OELD (organic electroluminescent display). The landing guidance device 220 is not limited to this, and may include, for example, a voice output device (speaker or the like) that outputs guidance information by voice in addition to or instead of the display device. The destination floor registration device 210 and the landing guidance device 220 may be configured as one device.

The group management control device 100 allocates an elevator (unit) on which the user rides among a plurality of elevators in response to a landing call including the destination floor designated by the user. The group management control device 100 determines the elevator to be assigned in consideration of, for example, the destination floor designated by the user using the destination floor registration device 210 and the operation information indicating the operating status of each elevator. As described above, the elevator system 1 of the present embodiment can be realized as a group management elevator system called DCS (Destination Control System) in which the user can specify the destination floor at the landing.

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

The elevator control devices 10a, 10b, and 10c control the ascent and descent of the lower floor elevator 2a belonging to the elevator bank 3a, the two-way elevator 2b belonging to the elevator bank 3b, and the upper floor elevator 2c belonging to the elevator bank 3c, respectively. .. Note that FIG. 2 shows only one elevator in each elevator bank for convenience of explanation. The elevator control devices 10a, 10b, and 10c are installed, for example, in the hoistway of each elevator, in the machine room, and the like.

When the destination floor registration device 210 performs the destination floor registration operation and the group management control device 100 determines the elevator to be operated, the elevator control devices 10a, 10b, and 10c of the elevator (allocated car) Determine the destination floor, movement direction (elevation direction), movement speed, etc., and operate the assigned car.

The group management control device 100 and the elevator control devices 10a, 10b, and 10c are configured by a microcomputer equipped with a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and the like. Can be done.

Next, the details of the function of the group management control device 100 will be described. The group management control device 100 includes an allocation 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 destination floor transmitted from the destination floor registration device 210 and the operation information transmitted from the elevator control devices 10a, 10b, and 10c, and sets the destination floor designated by the user. Allocate the optimum elevator for the landing call including.

The congestion estimation unit 102 estimates the congestion status of each of the standby area 8 and the standby area 9. For example, the congestion estimation unit 102 compares the number of registrations of each destination floor using each waiting area and the threshold value set for each waiting area as the value of the number of registrations that may be congested, and the number of registrations is larger than the threshold value. In some cases, it is estimated that the waiting area is congested.

When the two-way elevator 2b is assigned by the allocation unit 101, the determination unit 103 determines which of the two-way elevator 2b doors to open and close according to the congestion situation estimated by the congestion estimation unit 102. For example, when it is estimated that the standby area 8 is congested, 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 that opens and closes. Further, when it is estimated that the standby area 9 is congested, 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 that opens and closes.

In the present embodiment, even when the two-way elevator 2b is assigned to the landing call with the higher floor as the destination floor, if the waiting area 9 common to the higher floor elevator 2c is congested, the waiting area 9 is congested. The door 4b-1 that can be opened and closed in the direction of the standby area 8 is determined as the door that opens and closes. Similarly, even if the two-way elevator 2b is assigned to the landing call with the lower floor as the destination floor, if the waiting area 8 common to the lower floor elevator 2a is congested, the waiting area The door 4b-2 that can be opened and closed in the direction of 9 is determined as the door that opens and closes.

With such a configuration, for example, even if there are many users whose destination floor is the lower floor (higher floor) and the two-way elevator group is assigned to the lower floor (higher floor), the lower floor It is possible to avoid congestion of the landing for (higher floors). As a result, it is possible to avoid a decrease in elevator operating efficiency.

The determination unit 103 waits when, for example, the two-way elevator 2b is assigned to the landing call with the higher floor as the destination floor, and the waiting area 9 common to the higher floor elevator 2c is not congested. The door 4b-2 that can be opened and closed in the direction of the area 9 may be determined as the door that can be opened and closed. Similarly, when the two-way elevator 2b is assigned to the landing call with the lower floor as the destination floor and the waiting area 8 common to the lower floor elevator 2a is not congested, the determination unit 103 similarly determines. The door 4b-1 that can be opened and closed in the direction of the standby area 8 may be determined as the door that opens and closes.

Further, when both the standby area 8 and the standby area 9 are congested, the determination unit 103 may determine as a door that opens and closes a door that can be opened and closed in the direction of the standby area according to the destination floor. A door that can be opened and closed in the direction of a waiting area with relatively low congestion may be determined as a door that opens and closes.

The notification control unit 104 controls notification of information to the elevator control devices 10a, 10b, 10c, the landing guidance device 220, and the like. For example, the notification control unit 104 notifies the elevator control device corresponding to the elevator assigned by the allocation unit 101 that it responds to the destination floor registration (landing call) specified by the user. Further, the notification control unit 104 notifies the elevator control device 10b that controls the two-way elevator 2b of the door determined to be opened and closed by the determination unit 103.

Further, the notification control unit 104 controls the landing guidance device 220 so as to notify the user who operated the landing call of the landing corresponding to the door determined to be opened and closed by the determination unit 103. Further, the notification control unit 104 may control the elevator control devices 10a, 10b, and 10c so as to notify the user of the two-way elevator 2b of the destination floor of the two-way elevator 2b. For example, the notification control unit 104 uses an output device such as a display device and a voice output device provided in each elevator or each standby area to provide a two-way elevator 2b to a user waiting in the standby area 8 or the standby area 9. You may notify the destination floor of. As a result, it is possible to prevent the user from making a mistake in riding and further improve the operating efficiency of the elevator.

Next, an example of the operation method of the elevator system 1 configured in this way will be described with reference to FIG. FIG. 3 is a flowchart showing an example of an operation method of the elevator system 1 of the first embodiment.

The allocation unit 101 determines whether or not the destination floor has been registered by the destination floor registration device 210 (step S101). If the destination floor is not registered (step S101: No), the process is repeated until it is registered. When the destination floor is registered (step S101: Yes), the allocation unit 101 determines the elevator to be allocated from the registered destination floor, the operation information of each elevator, and the like (step S102).

The notification control unit 104 notifies the elevator control device that controls the assigned elevator among the elevator control devices 10a, 10b, and 10c that the elevator has been assigned (step S103).

The allocation unit 101 determines whether or not the two-way elevator 2b has been allocated (step S104). When the two-way elevator 2b is assigned (step S104: Yes), the congestion estimation unit 102 estimates whether or not the low-level standby area 8 or the high-level standby area 9 is congested (step S105).

When the standby area 8 or the standby area 9 is congested (step S105: Yes), the determination unit 103 determines the door 4b-1 and the door 4b-2 which can be opened and closed in the direction of the non-congested standby area. Is determined as a door to be opened and closed (step S106).

The notification control unit 104 sets the boarding guide device 220 so as to notify the user of the information indicating that the waiting area corresponding to the determined door is the landing and the information indicating the determined elevator (unit). Control (step S107). Further, the notification control unit 104 notifies the elevator control device 10b that controls the two-way elevator 2b of information on the door determined to be opened / closed (step S108).

Upon receiving the notification, the elevator control device 10b controls the two-way elevator 2b so as to open and close the determined door. As a result, the user can get on the two-way elevator 2b from the guided landing.

Further, the notification control unit 104 controls the elevator control device 10b so as to notify the user of the two-way elevator 2b of the destination floor (step S109).

When it is determined in step S104 that the two-way elevator 2b is not assigned (step S104: No), and when it is determined in step S105 that the standby area 8 or the standby area 9 is not congested (step S105: No), the notification control unit 104 notifies the user of information indicating that the waiting area corresponding to the elevator assigned according to the destination floor is the landing, and information indicating the assigned elevator (unit). As described above, the landing guidance device 220 is controlled (step S110).

After step S109 and step S110, among the elevator control devices 10a, 10b, and 10c, the elevator control device that controls the assigned elevator controls the operation of the elevator according to the registered destination floor (step S111).

As described above, in the elevator system 1 of the present embodiment, when the waiting area for the lower floors or the waiting area for the upper floors is congested and the two-way elevator is assigned, the waiting area is not congested. Guide the user to get on and decide which door to open and close the two-way elevator. This makes it possible to alleviate congestion at the landing and improve the operating efficiency of the elevator.

(Second Embodiment)
The elevator system of the second embodiment further includes a function of estimating the congestion status at the current time from the usage status of the elevator in the past. FIG. 4 is a schematic diagram showing an example of the system configuration of the elevator system of the second embodiment. As shown in FIG. 4, the elevator system of the second embodiment includes a group management control device 100-2, a plurality of elevator control devices 10a, 10b, 10c, a destination floor registration device 210, and a landing guidance device 220. , Lower floor elevator 2a, two-way elevator 2b, and higher floor elevator 2c.

In the second embodiment, the point that the storage unit 121-2 is provided in the group management control device 100-2, the function of the congestion estimation unit 102-2, and the function of the determination unit 103-2 are the first embodiments. It is different from the form. Since other configurations are the same as those in FIG. 2 showing the system configuration of the first embodiment, the same reference numerals are given and the description thereof will be omitted.

The storage unit 121-2 stores a usage status database showing the usage status of the elevator in the past. The usage status database stores information indicating the congestion status such as the number of users (the number of registrations on the destination floor) for each time zone and each waiting area. The time zone may be represented not only with the time (hour, hour, minute, etc.) but also with information such as the day of the week, the month, and the season. The storage unit 121-2 can be composed of a storage medium such as a ROM, a RAM, an HDD (Hard Disk Drive), and an SSD (Solid State Drive).

The congestion estimation unit 102-2 further has a function of estimating the current congestion status by referring to the usage status 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 defined in the usage status database. The congestion time zone is, for example, a time range defined as a time when the number of users exceeds a predetermined threshold value. The busy time zone is, for example, a work time zone and a break time zone, but is not limited to these.

When the two-way elevator 2b is assigned by the allocation unit 101 and the congestion estimation unit 102-2 determines that the current time is included in the congestion time zone, the determination unit 103-2 sets the congestion time zone. The door in the direction of the landing (standby area) defined as the landing that is not crowded is determined as the door that opens and closes the two-way elevator 2b.

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

Since steps S201 to S204 are the same as steps S101 to S104 of FIG. 3 showing an operation method of the elevator system of the first embodiment, the description thereof will be omitted.

When the two-way elevator 2b is assigned (step S204: Yes), the congestion estimation unit 102-2 determines whether or not the current time is included in the preset congestion time zone (step S205). When the current time is included in a preset congestion time zone (step S205: Yes), the determination unit 103-2 opens a door that can be opened and closed in the direction of a standby area that is not congested during this congestion time zone, in the two-way elevator 2b. It is determined as a door to open and close (step S207).

When the current time is not included in the preset congestion time zone (step S205: No), the congestion estimation unit 102-2 is in the low-level standby area 8 or high, as in step S105 of the first embodiment. It is estimated whether or not the standby area 9 of the hierarchy is congested (step S206).

Subsequent processes (steps S208 to S212) are the same as steps S107 to S111 of FIG. 3 showing an operation method of the elevator system of the first embodiment, and thus description thereof will be omitted.

The congestion estimation unit 102-2 not only determines whether or not the current time is included in the preset congestion time zone, but also actually causes congestion to the same extent as or higher than the preset congestion time zone. You may judge whether or not. For example, in the congestion estimation unit 102-2, when the current time is included in the preset congestion time zone, the number of registered destination floors at the current time is stored in association with the congestion time zone. Determine if it is greater than or equal to the number. When the number of registrations on the destination floor at the current time is equal to or greater than the number of memorized registrations, the determination unit 103-2 opens a door of the two-way elevator 2b that can be opened and closed in the direction of the waiting area that is not congested during this busy time zone. Determined as a door that opens and closes.

If the number of registrations on the destination floor at the current time is less than the number of stored registrations, the congestion estimation unit 102-2 may use the low-level standby area 8 or the high-level standby area 8 or the high-level standby area 8 as in step S105 of the first embodiment. It suffices to estimate whether or not the waiting area 9 is congested.

The congestion estimation unit 102-2 may determine whether the current congestion status is the same as the congestion status set in the preset congestion time zone. For example, the congestion estimation unit 102-2 calculates the difference between the number of registered destination floors at the current time and the number of registered destination floors stored in association with the congestion time zone, and when the difference is less than or equal to the threshold value, It may be estimated that the landing (waiting area) associated with the busy time zone is congested.

As described above, in the present embodiment, when the preset congestion time zone is reached, the door that opens and closes the door that can be opened and closed in the direction of the waiting area that is estimated not to be congested with reference to the past congestion situation. And guide the user to this waiting area. As a result, it is possible to further reduce congestion at the landing and further improve the operating efficiency of the elevator.

(Modification example)
In the modified example, a function of determining the door to open / close the two-way elevator is further added according to the position (standing position) of the user in the two-way elevator. FIG. 6 is a flowchart showing an example of an operation method of the elevator system of the modified example. Note that FIG. 6 shows an example in which a modified example is applied to the first embodiment. Similar modifications can be applied to the second embodiment.

In this modification, the determination unit 103 determines which of the two-way elevator 2b doors to open and close according to the position of the user in the two-way elevator 2b. The determination unit 103 determines, for example, the door closer to the user's position as the door to be opened / closed. With such a configuration, the user can get off the car more smoothly.

The determination unit 103 may determine as a door that opens and closes the door farther from the user's position. With such a configuration, when another user gets into the car of the two-way elevator 2b, it is necessary for the user who is already in the car to move in the car or to get off the car once. It disappears.

The position of the user in the two-way elevator 2b can be determined, for example, by analyzing an image obtained from an image pickup device (camera or the like) provided in the car of the two-way elevator 2b. The determination unit 103 can obtain an image from the image pickup device in the car, for example, via the elevator control device 10b. The method of finding the position of the user is not limited to this.

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

Since steps S301 to S304 are the same as steps S101 to S104 of FIG. 3 showing an operation method of the elevator system of the first embodiment, the description thereof will be omitted.

When the two-way elevator 2b is assigned (step S304: Yes), the determination unit 103 determines whether or not there is a user in the two-way elevator 2b (step S305). When there is a user in the two-way elevator 2b (step S305: Yes), the determination unit 103 determines the door in the direction corresponding to the position of the user in the two-way elevator 2b as a door to open and close (step). S306).

When there is no user in the two-way elevator 2b (step S305: No), the congestion estimation unit 102 has the low-level standby area 8 or the high-level standby area 9 as in step S105 of the first embodiment. It is estimated whether or not it is crowded (step S307).

Subsequent processes (steps S308 to S313) are the same as steps S106 to S111 of FIG. 3 showing an operation method of the elevator system of the first embodiment, and thus description thereof will be omitted.

When applying this modification to the second embodiment, for example, after it is determined in step S305 that there is no user in the two-way elevator 2b, the determination in step S205 of FIG. 5 is executed. It may be configured.
