Abstract

PROBLEM TO BE SOLVED: To solve the following problems: when two elevators with doors fully closed and adjacent to each other in the same hoistway stop on the same floor, and when neither car call nor floor call is registered in control devices of both elevators, a car call and a car call are received simultaneously, or reception of a car call and allocation of a floor call occur simultaneously in both control devices; and when the floor corresponding to the calls is located in the same direction, the elevators move side by side and generate large wind noise to disturb passengers.SOLUTION: A control device is set in enabled state or disabled state for moving an elevator. When neither car call nor floor call is registered in both control devices, both control devices are set in the disabled state. If a car call reception and a floor call reception, or a car call reception and allocation of a floor call occur simultaneously. only one control device is set to the enabled state. After one elevator starts moving, when the elevators are not likely to move side by side, the other control device is set to the enabled state.

Description

The present invention relates to an operation system and an operation method for avoiding adjacent elevators running in parallel (running in parallel) in the same hoistway.

When two elevators adjacent in the same hoistway run side by side, a loud wind noise is generated to give passengers anxiety. Therefore, a wind noise countermeasure as shown in Patent Document 1 has been proposed. It predicts the time it takes for two adjacent units to depart from their respective stop floors, and if there is a difference between these times, there is a risk of running in parallel. The stand is to prevent departure for a certain period of time. As for which departure will be given priority, if both elevators are in the same direction, give priority to the elevator in front, give priority to the elevator with the lower service index, or special operation It has been proposed that priority is given to the elevator of this type and priority is given to the elevator with the longer duration of the door open state.

As described above, in Patent Document 1, as a case where two adjacent vehicles run side by side, the time until each elevator departs from the stop floor is predicted, and the case where the difference between the times falls within a predetermined range is targeted. However, other than that, there is a case where both elevators run in parallel due to duplicate call registration.

This is a case where the following conditions (i) and (ii) are both satisfied.
(I) It is composed of a “control device” that controls each elevator and a “group management device” that links these control devices, each control device accepts a car call, and the group management device accepts a hall call, A system that assigns calls to one controller.
(Ii) When both elevators stop on the same floor and the doors are fully closed, and neither the car call nor the hall call is registered in both control devices, both the car call reception and the car call reception are duplicated. Or the floors designated by those calls are in the same direction.

In the above, “car call” is a request for an elevator to go to a floor specified by pressing a button in the car, and “landing call” is specified by pressing a button at the landing. This is a request for an elevator to come to the floor. These floors are referred to as “floor designated by the car call” and “floor designated by the hall call”. The basket call and the hall call are collectively referred to as “call”.

The words “register” and “delete” are used in the following meanings. That is, each control device departs the elevator controlled by itself toward the floor designated by the accepted car call or the assigned hall call and arrives at those floors. When a car call is accepted or a hall call is assigned, each control device “registers” the call in the internal storage area, and when the elevator arrives at the floor designated by the call, the registration of the call is made. "Delete.

Hereinafter, the case where the hall call assignment and the hall call assignment overlap in both control devices is shown in FIG. 7, the case where the car call reception and the car call reception overlap are shown in FIG. 8, and the case where the car call reception and the hall call assignment overlap. Will be described with reference to FIG. 7 to 9, regarding the Ele A control device and the Ele B control device that control each elevator named Ele A and Ele B, how the internal state and interaction with the group management device change over time. Is shown.

Each of the two control devices has an internal state of whether or not departure is possible, and takes a value of “departure is possible” or “departure is impossible” (both are collectively referred to as “departure availability”). The initial setting is permitted to start, and is switched by a departure permission instruction from the group management device. When there is a car call reception or a hall call assignment, each control device starts an elevator that it controls if it can be started, and does not start if it cannot start.

FIG. 7 explains that both elevators do not run in parallel when the hall call assignment and the hall call assignment overlap. This is a case where the group management device accepts two hall calls that specify to go to the upper floor, assigns one hall call to the Ele A control device, and simultaneously assigns the other hall call to the Ele B control device. At this time, the group management device assigns the hall call to both control devices, and at the same time, instructs only the elevator B not to start, thereby preventing both elevators from running in parallel.

With reference to FIG. 8, it will be described that both elevators run in parallel when the car call reception and the car call reception overlap. This is a case where the Ele A control device accepts a car call that specifies going to the upper floor, and at the same time, the Ele B control device also accepts a car call that designates going to the upper floor. When receiving the basket call, the Ele A control device immediately starts the Ele A and notifies the group management device of the basket call. As soon as the Ele B control device accepts the cage call, it starts Ele B and also notifies the group management device of the cage call. The group management device knows that the car call acceptance has occurred in both elevators and instructs the elevator B not to leave, but the elevator B has already started and cannot follow the instruction. Therefore, both elevators were supposed to run side by side.

The problem at this time is that the elevators controlled by both control devices accept the car call immediately, whereas the group management device recognizes the car call one tempo later, Even if the control device is instructed not to leave, it is not in time.

With reference to FIG. 9, it will be described that both elevators run in parallel when the car call acceptance and the hall call assignment overlap. This is a case where the EL A control device accepts a car call that designates going to an upper floor and at the same time the group management device accepts a hall call that designates going to an upper floor. When receiving the basket call, the Ele A control device immediately starts the Ele A and notifies the group management device of the basket call. When the group management device receives the hall call, the group management device assigns the hall call to the Ele B control device, and the Ele B control device starts the Ele B immediately. The group management device is notified of the car call from the Ele A control device after accepting the hall call, so it does not recognize that the hall call assignment and the car call acceptance are duplicated, and cannot leave the Ele B control device. There is no command. Therefore, both elevators were supposed to run side by side.

The problem at this time is that the group management device accepts the hall call and then assumes that the car call may be notified from a control device different from the control device to which the hall call is assigned. Is that the control device to which the hall call is assigned should be instructed to leave, but no such assumption is made.

Japanese Patent No. 3412204

As described above, both the elevators that are adjacent in the same hoistway stop on the same floor and the doors are fully closed, and there is no call registration in the control device of both elevators, and the car call reception and the car call reception If there is overlap between the car call reception and hall call assignment, and the floors designated by those calls are in the same direction, both elevators may run side by side and wind noise may occur. It was a problem. The present invention is intended to solve this problem.

The present invention includes a control device that controls each of two elevators adjacent in the same hoistway and a group management device that links both control devices, and is defined as (1) to (3) below. The elevator operation system is characterized by the following (4).
(1) The control device accepts a basket call and notifies the group management device. The control device registers the accepted car call, and deletes the registration of the car call when an elevator controlled by the control apparatus arrives at a floor designated by the car call.
(2) The group management device accepts a hall call and assigns the accepted hall call to the control device. The control device registers the assigned hall call, and deletes the registration of the hall call when an elevator controlled by itself arrives at a floor designated by the hall call.
(3) The group management device instructs the state of the control device to be permitted or not permitted. When the car call or the hall call is registered, the control device starts the elevator that it controls if it can start, and does not start the elevator if it cannot start.
(4) The group management device departs from both control devices when both elevator doors stopped on the same floor are fully closed and no landing call or basket call is registered in both control devices. Command not to be allowed. After that, if a car call or a hall call is registered in at least one control device, at least one control device is instructed to be allowed to start.

Moreover, this invention has a control apparatus which controls each of the two elevators which adjoin in the same hoistway, and in the operation method of an elevator prescribed | regulated as following (1)-(3), following (4) It is characterized by.
(1) Let the control device accept a basket call. The accepted car call is registered in the control device, and when the elevator controlled by the car arrives at the floor designated by the car call, the car call registration is deleted.
(2) Assign the accepted hall call to the control device. The assigned hall call is registered in the control device, and the registration of the hall call is deleted when an elevator controlled by the elevator arrives at a floor designated by the hall call.
(3) The state of the control device is allowed to start or cannot be started. When the car call or the hall call is registered in the control device, the elevator controlled by itself is started if the state of the vehicle can be started, and the elevator is not started if the departure is impossible.
(4) When both elevator doors stopped on the same floor are fully closed and neither the car call nor the hall call is registered in both control devices, the states of both control devices are disabled. Thereafter, when a car call or a hall call is registered in at least one control device, it is permitted to start with respect to at least one control device.

Since both elevators stop on the same floor and the doors are fully closed and there is no call registration in both control units, both control units switch their status to not ready, so both control units Even if the car call reception and the car call reception overlap, or if the car call reception and the hall call assignment overlap, it is possible to switch to only one controller after recognizing that. Only one elevator will leave immediately. Therefore, since both elevators do not run in parallel, the generation of wind noise can be avoided.

Data processing processing and stored content rewriting processing of the printed circuit are possible. Thus, each means in each apparatus can be configured. In addition, data exchange between the devices can be configured by transmission / reception processing of the printed circuit.

When the EL A control device 10 and the ELLE B control device 20 accept a car call or are assigned a hall call, they register the car call or the hall call in the internal storage area, and the floor designated by those calls. When the elevator arrives, the registration will be deleted.

[Relationship between each means]
Next, the relationship between each means which comprises the Ele A control apparatus 10, the Ele B control apparatus 20, and the group management apparatus 30 is described.

When assigning a hall call from the group management device 30 to the Ele A control device 10, hall call data is transmitted from the hall call assigning means 32 to the hall call receiving means 12. Further, when assigning a hall call from the group management device 30 to the Ele B controller 20, the hall call data is transmitted from the hall call assigning means 32 to the hall call receiving means 22.

When notifying the car call to the group management device 30 from the Ele A control device 10, the car call data is transmitted from the car call notifying means 15 to the car call recognizing means 35. Further, when the elevator B controller 10 notifies the group manager 30 of a car call, the car call data is transmitted from the car call notifying unit 25 to the car call recognizing unit 35.

When the Ele A control device 10 notifies the group management device 30 of the state of the Ele A, the Ele state notification unit 16 transmits the Ele state data to the Ele state recognition unit 36. When the Ele B control device 20 notifies the group management device 30 of the state of Ele B, the Ele state data is transmitted from the Ele state notification unit 26 to the Ele state recognition unit 36.

In the group management device 30, the departure permission / inhibition command means 33 departs from the hall call data from the hall call assignment means 32, the car call data from the car call recognition means 35, and the elevator state data from the elevator state recognition means 36. Generate availability data.

When commanding whether or not to leave from the group management device 30 to the ELE A control device 10, departure permission / inhibition data is transmitted from the departure permission / inhibition command means 33 to the departure permission / rejection receiving means 13. Further, when instructing whether or not to leave from the group management device 30 to the Ele B control device 20, departure permission / inhibition data is transmitted from the departure permission / inhibition command means 33 to the departure permission / rejection receiving means 23.

If there is the hall call data from the hall call receiving means 12 or the car call data from the car call receiving means 14 in the Ele A control device 10 and the departure possibility data from the departure possibility receiving means 13 is permitted to depart. Then, the traveling control means 19 starts the EL A from the stop floor, travels to the floor designated by the call, and arrives. Further, in Ele B control device 20, there is hall call data from hall call receiving means 22 or basket call data from basket call receiving means 24, and departure permission / inhibition data from departure permission / rejection receiving means 23 can be left. In this case, the traveling control means 29 starts ELE B from the stop floor, travels to the floor designated by the call, and arrives.

[Control procedure of group management device]
Hereinafter, the control procedure of the group management apparatus 30 will be described with reference to FIG. The procedure is a state in which Ele A and Ele B adjacent in the same hoistway stop on the same floor and the door is fully closed, and there is no call registration in Ele A control device 10 and Ele B control device 20 Thus, when a new call is registered in at least one control device, the group management device 30 determines when and how to issue a departure permission instruction to the EL A control device 10 or ELLE B control device 20. is there. It should be noted that the initial value of the start / stop status can be set for both the control devices 10 and 20.

First, in step S1, the group management device 30 determines whether “there is no registration of a car call or a hall call in both control devices 10 and 20, and both elevators are stopped on the same floor”. If NO, step S1 is repeated, and if YES, the process proceeds to step S2. In step S2, it is determined whether or not "the doors are fully closed for both elevators". If NO, the process returns to step S1, and if YES, the process proceeds to step S3. In step S3, both control devices 10 and 20 are instructed to switch from departure possible to departure impossible.

In the subsequent step S4, it is determined whether or not “the first predetermined time has elapsed after at least one basket call or hall call is registered in at least one control device 10 or 20”. The first predetermined time means that when the group management device 30 accepts a hall call and the Ele A control device 10 or the Ele B control device 20 accepts a cage call, how much time elapses from that point. This is an estimate of the time that the group management device 30 can recognize the basket call (for example, 0.1 second). If the determination result in step 4 is NO, step S4 is repeated, and if YES, the process proceeds to step S5. In step S5, it is determined whether “the call is registered in” or “whether it is registered in either” of the Ele A control device 10 and the Ele B control device 20.

If it is determined in step S5 that the call is registered only in the Ele A control device 10, the process proceeds to step S11. If it is determined that the call is registered only in the Ele B control device 20, the process proceeds to step S21.

If it is determined in step S5 that a call is registered in both control devices 10 and 20, the process proceeds to step S6. Depending on whether the floor designated by the call registered first in the EL A control device 10 is above or below the stop floor, the EL A control device 10 determines whether the destination direction of the EL A is upward or downward. To do. Similarly, the Ele B control device 20 also determines the destination direction of the Ele B. In step S6, it is determined whether the destination direction determined by the Ele A control device 10 and the destination direction determined by the Ele B control device 20 are the same direction. If NO, the process proceeds to step S31, and if YES, the process proceeds to step S7. In step S7, “as a call specifying that both control devices 10 and 20 go to the same destination direction floor, the cage call is not registered in the EL A control device 10 but registered in the ELLE B control device 20. It is determined whether or not. If NO, the process proceeds to step S11, and if YES, the process proceeds to step S21.

In step S11, the ELE A control device 10 is instructed to switch from departure impossible to departure possible. Then, the Ele A control device 10 departs the Ele A toward the floor designated by the registered call. In subsequent step S12, the group management device 30 determines whether or not a second predetermined time has elapsed since the departure of the EL A. The second predetermined time is an estimate of how long it takes for one of the adjacent elevators to start before the other starts to avoid the generation of wind noise due to parallel running. If the determination result of step S12 is NO, step S12 is repeated, and if YES, the process proceeds to step S13. In step S13, the ELE A control device 10 is instructed to switch from departure impossible to departure possible. Then, it returns to step S1.

In step S21, the Ele B control device 20 is instructed to switch from departure impossible to departure possible. Then, the Ele B control device 20 departs the Ele B toward the floor designated by the registered call. In subsequent step S22, the group management device 30 determines whether or not a second predetermined time has elapsed since the departure of the elele B. If the determination result is NO, step S22 is repeated, and if it is YES, the process proceeds to step S23. In step S23, the ELE B control device 20 is instructed to switch from departure impossible to departure possible. Then, it returns to step S1.

In step S31, both control devices 10 and 20 are instructed to switch from departure impossible to departure possible. Then, it returns to step S1.

[Details when the destination direction is the same direction]
In step S7 described above, when the destination directions of ELE A and ELE B are the same direction, different correspondences are made depending on whether or not a basket call specifying the floor in the direction is registered. Details will be described. There are two ways depending on whether or not such a car call is registered in the Ele A control device 10, and there are two ways depending on whether or not it is registered in the Ele B control device 20. This will be described below.

The case where the car call is not registered in both the control devices 10 and 20 (only the hall call is registered) will be described with reference to FIG. In this case, let us consider a case where after the group management device 30 receives two hall calls in duplicate, one is assigned to each of the control devices 10 and 20. At this time, the group management device 30 instructs the ELE A control device 10 to assign a hall call and at the same time to switch from departure impossible to departure possible. On the other hand, only a hall call is assigned to the Ele B control device 20, and no instruction is given to switch from departure impossible. Therefore, only Ele A departs, and parallel running of Ele A and Ele B is avoided. The above is the same even when the number of hall calls accepted is more than one.

The case where the car call is registered in both control devices 10 and 20 (including both cases where there is a registration of the landing call and when there is no registration) will be described with reference to FIG. In this case, consider a case where both the control devices 10 and 20 receive one cage call, each is notified to the group management device 30, and the group management device 30 recognizes the basket call in duplicate. At this time, the group management device 30 instructs the ELE A control device 10 to switch from departure impossible to departure possible. On the other hand, no instruction is given to the Ele B control device 20 to switch from departure impossible. Therefore, only Ele A departs, and parallel running of Ele A and Ele B is avoided. The above is the same even when the number of basket calls accepted is greater than one.

As described above, when the car call is not registered in both elevators, or when the car call is registered in both elevators, only the elevator A is started.

This is a case where a car call is registered in ELe A (including both cases where there is a registration of a hall call), and a car call is not registered in ELE B (only a hall call is registered) The case is described with reference to FIG. In this case, the group management device 30 receives one hall call and then assigns it to the Ele B control device 20, and the Ele A control device 10 receives one cage call and then notifies the group management device 30. Consider a case in which the group management device 30 recognizes two or more of them. At this time, the group management apparatus 30 instructs the ELE A control apparatus 10 to switch from departure impossible to departure possible. On the other hand, only a hall call is assigned to the Ele B control device 20, and no instruction is given to switch from departure impossible. Therefore, only Ele A departs, and parallel running of Ele A and Ele B is avoided. The above is the same even when the number of hall calls accepted is more than one and when the number of basket calls accepted is more than one.

This is the case where a car call is registered in ELE B (including both cases where there is a registration of a hall call), and no car call is registered in ELA A (only a hall call is registered) The case is described with reference to FIG. In this case, the group management device 30 receives one hall call and then assigns it to the Ele A control device 10, and the Ele B control device 20 receives one basket call and then notifies the group management device 30. Consider a case in which the group management device 30 recognizes two or more of them. At this time, the group management device 30 instructs the Ele B control device 20 to switch from departure impossible to departure possible. On the other hand, only a hall call is assigned to the EL A control device 10, and no instruction is given to switch from departure impossible. Therefore, only ELE B departs, and parallel running of ELE A and ELE B is avoided. The above is the same even when the number of hall calls accepted is more than one and when the number of basket calls accepted is more than one.

As described above, when an elevator in which a car call is registered and an elevator in which a car call is not registered are going to start at the same time, only the elevator in which the car call is registered is used.

[Effects of the embodiment]
According to the embodiment described above, the following effects can be obtained. That is, in a state where both elevators adjacent in the same hoistway are stopped on the same floor and the doors are fully closed and no call registration is made to both control devices 10 and 20, the group management device 30 is configured to both control devices. 10 and 20 are instructed to switch the departure allowance state from “departure permitted” to “departure not permitted”. Thereafter, in both control devices 10 and 20, the basket call reception and the basket call reception overlap, or the basket call reception and the landing call. Even if the assignments are duplicated, after the group management device 30 recognizes this, it is possible to instruct only one control device to switch to start, so that only one elevator will start immediately. . Therefore, since both elevators do not run in parallel, the generation of wind noise can be avoided.

Further, when the group management device 30 receives the hall call, the hall call is assigned to the Ele B control device 20, and the car call notification from the Ele A control device 10 is waited until the first predetermined time elapses from that time. Therefore, in a situation where the departure of Ele B by the hall call and the departure of Ele A by the cage call conflict, it is possible to instruct only the Ele A control device 10 to switch to departable, and only Ele A departs. Without both elevators running side by side. Even if the roles of Ele A and Ele B are switched, only Ele B will start, and both elevators will not run in parallel.
