Description

Group management control elevator

Technical Field

Embodiments of the present invention relate to group management control elevators.

Background

In a high-rise building, a plurality of elevators are installed, and a group management control system is used to efficiently operate the elevators. In this group management control system, control is performed to allocate an appropriate elevator to a call at an elevator boarding location, thereby improving the transportation efficiency.

The number of users of an elevator varies greatly according to time periods. In the morning work hours, noon break, and evening work hours, the users may concentrate on a specific floor, and the users may wait for the arrival of the car for a long time, and the waiting people may not all ride on the car. In elevator group management control, it is an important issue to prevent the operation performance from being lowered in a time zone where users are concentrated.

Conventionally, in order to improve the transport efficiency in the case of congestion, a group management control method called zone planning (zoning) has been proposed. In this zoning plan method, the number of floors to which a hall call can be answered is limited, and thus the group management control method is intended to improve the transport efficiency. For example, patent document 1 proposes the following: an elevator hall call response table is created based on past needs so as to equalize the transport load of each car, and an elevator is allocated to an elevator hall call based on the elevator hall call table (patent document 1).

In recent years, a destination floor registration system for an elevator hall is used in elevators performing group management control. In such an elevator, an elevator-boarding destination floor registration device is provided at an elevator-boarding location, and when a user operates the elevator-boarding destination floor registration device to register a destination floor, an elevator is assigned, and the user can directly move to the destination floor by only riding the guided (notified) elevator. In addition, the transportation efficiency can be improved by sharing a plurality of elevators for each destination floor registered by the destination floor registration device at the elevator boarding location.

However, in a time zone during congestion, the users may be concentrated significantly. In the working hours, for example, 95% of all the users in the total demand may be concentrated in the elevator hall of 1 floor.

In such a case, the following situation occurs: a long wait is required until the car returns to floor 1, and even if the car returns, the car may not be transported completely, and the elevator may not run to more and more users. In such a large change in demand, there is a problem that the above-described response sharing of hall calls cannot be completely handled.

The present invention has been made in view of the problems of the conventional techniques, and an object of the present invention is to: provided is a group management control elevator which can appropriately meet the needs of elevators and efficiently provide the operation of elevators even if there is a concentration of users to a specific floor.

Detailed Description

Hereinafter, an embodiment of group management control of elevators according to the present invention will be described with reference to the drawings.

Fig. 1 shows a boarding area of a group management elevator to which the present invention is applied. In this building, floors to be served by the operation of the elevator are 1 floor to P floor. The elevators are a-machines to X-machines, and their operation is managed by the group management control device 10. In the elevator boarding area of each floor, an elevator boarding destination registration device 12 or a vertical direction registration device 14 is provided.

The boarding destination registration device 12 is a device that enables a user to register a destination at the boarding location. The destination floor registration device 12 is installed on a specific floor, and in the present embodiment, is installed on a specific floor that is used in a particularly large number of floors, in addition to the floor 1 serving as a reference floor for group management control.

The vertical direction registration device 14 is provided at a floor different from the floor on which the destination floor registration device 12 is provided, and registers the moving direction of the car as a hall call. In the up-down direction registration device 14, when the user presses one of the up-direction button and the down-direction button that is desired to be moved, the user can perform a registration operation of a hall call in that direction. When the hall call is registered in the vertical direction registration device 14, the pressed button is turned on.

Next, the destination floor registration device 12 and the group management control device 10 at the boarding location will be described with reference to fig. 2.

In fig. 2, the boarding destination registration device 12 includes a boarding destination registration unit 15 that registers a destination input by a user using a numeric keypad (numeric keypad) or the like. The inputted car call registration information is transmitted to the assigned elevator deciding part 23, and the assigned elevator deciding part 23 decides which elevator of the appropriate elevator to respond to the car call from the destination floor registration device 12 at the elevator riding place. The car assignment result and the car call information are transmitted to the assigned car display output unit 27 and the destination floor display output unit 28, and the assigned car and the destination floor registration information indicating the destination floor are displayed on the assigned car display unit 16 and the destination floor display unit 17 of the destination floor registration device 12 at the elevator boarding location, respectively.

The result of the car assignment is transmitted to the assignment command output unit 25, and the assignment command output unit 25 transmits the assignment command so that the control unit of the assigned car among the control units 18a to 18x that control the operation of the cars 19a to 19x of the respective cars responds to the car call. Further, the car call registration command output unit 26 transmits a car call registration command to the control unit of the assigned elevator among the control units 18a to 18x of the respective elevators, and registers a car call to the control unit of the associated elevator.

In this way, when a user registers a desired destination floor from the boarding area destination floor registration device 12, a car call is automatically registered, and the user can wait until the landing entrance of the car displayed on the assigned car display unit 16, and can get to a desired floor by boarding the car.

In the group management control according to the present embodiment, in addition to the control of the normal operation, the car call response is shared in a constant pattern between the a-number machine and the X-number machine of the elevator.

Under normal operation, the group management control is executed in such a manner that: in response to hall calls from all floors, appropriate elevator numbers are assigned, and car calls to all floors can be registered.

In contrast, the response sharing mode is a mode in which the car calls registered in the destination floor registration device 12 at the boarding location on the specific floor are shared substantially equally among the machines so that the users can ride the cars of the machines substantially equally. In this response sharing mode, a destination floor in which a car call can be registered is set in advance for a plurality of car numbers, and a car call other than sharing cannot be registered.

In the present embodiment, in addition to the response sharing mode, there is a response sharing correction mode. The response sharing correction mode is as follows: in the case where improvement of the running service performance of the elevator cannot be predicted in the response sharing mode, the mode of the floor to be the actual destination floor is reduced from the destination floor of the shared car call.

The group management control device 10 controls the elevator car of an appropriate elevator to be responded to for the elevator hall call and the car call assignment. In fig. 2, the group management control device 10 includes a response assignment generating unit 22 that generates a pattern of response assignments for car calls of the elevators. Each car allocates the destination floor of the car call to which a response is possible according to the response allocation pattern generated by the response allocation generating unit 22. For example, when the destination floor registration device 12 registers a car call at a boarding floor of 1 floor, the car call of 2-4 floors as the destination floor is shared by the a-machine, and the car call of 5-7 floors and … are shared by the B-machine. Conversely, when the destination floor is registered in the destination floor registration device 12 at the elevator riding place, the car call is assigned to the car number sharing the registered destination floor in principle. Fig. 7 (a) shows an example of such a response sharing mode.

The response sharing mode is determined based on demand data generated according to the operation condition of the elevator. The demand generation unit 20 generates the demand data. The demand data is stored in the demand data storage unit 21. The response sharing generation unit 22 reads the required demand data from the demand data storage unit 21, and generates the above-described response sharing pattern for each elevator.

In the present embodiment, the response sharing generator 22 also determines whether or not there is a need to perform group management control according to the response sharing mode, based on the demand data.

When there is a necessity, the assigned elevator determining unit 23 assigns each elevator of the elevator to the car call based on the response sharing mode determined by the response sharing generating unit 22. In the present embodiment, when improvement of the operation performance such as elimination of congestion can be expected even when response sharing is performed before actual assignment, assignment to a car call based on the response sharing mode is performed. When improvement of the running performance cannot be predicted, the destination layer of each machine is changed in the destination layer changing unit 24 according to the corrected response sharing mode. This point will be described later.

Next, the process of determining the response allocation mode will be described in more detail with reference to the flowcharts of fig. 2 and 3 and fig. 5 to 7. In the following description, the floor 1 is set as a reference floor (reference floor), an elevator boarding request is determined, and response allocation to the elevator boarding request is described. The reason why 1 floor is used as the reference floor is that in the case of many buildings, 1 floor is used as the starting floor for elevator use. The reference floor is not limited to 1 floor depending on the building, but the processing contents are the same in this case.

In order to determine how each machine of the elevator should be allocated to respond, it is necessary to grasp the operation state of the elevator. Therefore, required data needs to be collected in advance before the response sharing generation process is executed. In fig. 2, every time the destination floor is registered, the destination floor registration information and information related to the operation status are transmitted from the boarding destination floor registration unit 15 to the demand generation unit 20 of the group management control device 10. Further, information on the direction of the hall call, the number of calls, and the like is also transmitted from the up-down direction registration device 14 to the demand generation unit 20. Based on these pieces of information, the demand generation unit 20 generates data such as where the departure floor is and where the destination floor is in each car call and/or hall call, the number of times and/or waiting time of each car call and/or hall call, and the like, and accumulates and stores the data in the demand data unit 21 as past demand data. Since the elevator boarding request of the elevator greatly varies depending on the time zone, the following determination processing for response sharing is executed several times a day at a plurality of predetermined times.

Therefore, in the flowchart of fig. 3, first, in step S1-1, it is determined whether or not there is a state in which there is a greater demand for boarding of floor 1 as a reference floor than the demand for elevators of the entire floors of the building. The response sharing generation unit 22 refers to past demand data in the current time slot from the demand data storage unit 21, and determines that the number of elevator boarding demands exceeds a predetermined determination criterion, for example, 95% of the total elevator boarding demands are concentrated on floor 1. Although the determination of the elevator boarding request is made based on the past request data in the above example, the number information of call registration at the elevator boarding location and the data of destination floor registration information may be directly acquired from the destination floor registration device 12 at the elevator boarding location, and the determination may be made in real time based on these data.

Next, in step S1-2, it is determined whether or not the running performance of the elevator provided to the user who rides the elevator from floor 1 is lower than a predetermined index. That is, it is determined whether or not there is a deterioration in the running performance. This is because, from only the concentration of the boarding demand determined in step S1-1, it is not necessarily known whether the running performance has deteriorated, as in the case where the number of users is not so many, for example. In the present embodiment, as an index that becomes a criterion for determining a deterioration in running performance, an average waiting time (average time from car call registration to arrival of a car) at the time of registration of a car call at level 1 is used. For example, when the average waiting time is 120 seconds and the maximum waiting time is 300 seconds, the deterioration of the drivability is determined when the allowable range of the waiting time exceeds a predetermined standard. The determination criterion is not limited to the waiting time. The determination may be made by combining or by using indices such as the cycle (one-round operation) time until the car returns to 1 floor and the number of floors stopped during the cycle.

When there is no problem in the boarding request and the operation performance in steps S1-1 and S1-2, the response sharing control is not required, and therefore, the operation performance based on the normal operation is continued (step S1-7) and the processing is terminated. In this normal operation, as shown in fig. 5, all the elevators can respond to hall calls and car calls at all the floors (all the floors).

Next, step S1-3 is a process of determining a pattern of response sharing for the car calls registered by the boarding area destination floor registration device 12 so that the user can ride the cars 19a to 19X of the a-size to the X-size machines as evenly as possible.

Here, fig. 6 is a table showing the following example: for example, in a group control elevator having 6 operations on 16 floors, the elevators use demand data (the number of registered car calls registered by the destination floor registration device 12 at the elevator boarding location) in a concentrated working time period (8 am to 9 am).

The elevator operation performance is significantly low when such an elevator riding demand is generated at 1 floor (reference floor).

Fig. 7 (a) shows an example of allocation of car calls between numbers in response allocation control (mode 1) in the present embodiment.

When the destination floor is registered in the destination floor registration device 12 at the elevator-taking position of 1 floor, the cars of the a-number machine to the E-number machine share only the car call with the floor indicated by o as the destination floor, as in the case where the a-number machine shares the car call with the 2-4 floors marked with o as the destination floor, and the B-number machine shares the car call with the 5-7 floors as the destination floor. As can be seen from fig. 6, in this example, the total registered car calls of the floors assigned to each car are not distributed substantially uniformly to the specific cars within the range of 100 to 140.

This allocation is because: from the data of the number of car calls registered in fig. 6, it is determined that there is a high possibility that the users having the substantially balanced number of people are transported by the respective machines from the machine a to the machine E.

In the present embodiment, the F-plane is excluded from the response sharing. The machine F can respond to a hall call and/or a car call to any floor other than the reference floor.

Next, the processing of step S1-4 is processing for determining whether or not the operation performance of the elevator can be improved when the response sharing determined in step S1-3 is performed. As a method of this determination, a method of simulating (simulation) whether or not the transportation can be smoothly performed without the passengers staying at the floor 1, or a method of simply calculating the waiting time and/or the cycle time of the car and performing statistical processing to determine whether or not these times can be shortened may be used. If it is determined that improvement is possible, the process proceeds to step S1-6, and the above-described response sharing mode (mode 1) is selected.

In the response sharing control based on the pattern 1, since the responses are shared so that the transportation load of each car is equalized for the car call, the car call is not biased to a part of the cars, the elevator riding demand concentrated on the 1 st floor can be effectively fulfilled (or processed), and the lowering of the running performance of the elevator due to the concentration of users can be improved.

On the other hand, if it is determined that the transportation performance of the elevator cannot be sufficiently improved by the response sharing in the mode 1, for example, if the average waiting time is 90 seconds and the maximum waiting time is 180 seconds, the routine proceeds to step S1-5.

In step S1-5, the processing for correcting the response assignment in the above-described mode 1 is performed (the mode for the response assignment after the correction is set to the mode 2).

Fig. 7 (B) shows an example of allocation of car calls between the respective elevators based on response allocation (pattern 2) in the present embodiment.

In the response sharing mode 2 of the present embodiment, the floors that can be the actual destination floor among the destination floors of the car calls assigned to each car in the mode 1 are limited, and the floor that has the largest number of passengers to be dropped is selected in a reduced manner (in the case where there are a plurality of such floors, there may be a plurality of floors).

For example, in the mode 1, when the destination floor is registered by the destination floor registration device 12 at the elevator riding position of 1 floor, the car call with 2-4 floors as the destination floor is shared by the a-number machine, but the number of passengers is large in the car call with 3 floors, and therefore, only 3 floors are set as the destination floor. Although car calls with the destination floors 2 and 4 are also received, in this case, the destination floor is changed as described later. The car call of the car in the destination floor of 5 to 7 is shared by the car in the B-class car, but the destination floor is 5. Hereinafter, the same applies to the machines from the machine C to the machine E, and the machines from the machine a to the machine E. The floor in the empty column is a floor that does not become a destination floor although a car call is received.

In such response sharing in the pattern 2, the destination floor is limited to the floor where the number of people getting off the car is large, and the travel service is preferentially performed between the floor 1 where the users are concentrated and the floor where the number of people getting off the car is large. As a result, the efficiency of user conveyance increases due to the reduction in the round trip time of the car. Further, since the mode for sharing the response is determined by the two measures of the mode 1 and the mode 2, it is possible to cope with various situations in which users are concentrated.

Next, a process of assigning a car number of an elevator to a car call when the destination floor registration device 12 registers the car call at the elevator riding place of floor 1 after the response sharing mode is determined as described above will be described with reference to a flowchart of fig. 4.

First, in step S2-1, the assigned car determination unit 23 determines whether or not the destination floor registration device 12 has newly received a car call at the boarding location of floor 1. When the call is accepted, the flow proceeds to step S2-1, where the control mode assigned to the current response is checked. In the case of the "normal operation", the normal distribution control is performed in step S2-3. Then, the assigned car is displayed on the assigned car display unit 16 of the destination floor registration device 12 at the boarding location (step S2-7), the assignment command is output from the destination floor display output unit 28 to the corresponding control unit among the control units 18a to 18X of the assigned car, and the car call registration command is output from the car call registration command output unit 26 (step S2-8). In the case of normal operation, since a car call or a hall call is received at any floor, for example, when 14 floors are registered as the destination floor by the destination floor registration device 12 at the boarding location of 1 floor, as shown in fig. 8 (a), the destination floor is displayed as 14 floors, and the machine number a is displayed assigned.

When the response sharing is "pattern 1", the process proceeds to step S2-4, and the assigned car determination unit 23 assigns a car that can be assigned with the response sharing in pattern 1. For example, when the destination floor registration device 12 registers the car calls of 9 floors and 14 floors at the elevator-taking place of 1 floor, the car call of 9 floors is assigned the machine C, and the car call of 15 floors is assigned the machine E, according to the assignment in fig. 7 (a). In the case of "mode 1", for example, when the destination floor registration device 12 registers 14 floors as the destination floor at the elevator riding position of 1 floor, as shown in fig. 8 (B), the destination floor is displayed as 14 floors, and the E-plane is assigned by sharing.

If the response sharing is "mode 2", the process proceeds to step S2-5, and assignment is performed to a car capable of assignment based on the response sharing of mode 2. For example, when the destination floor registration device 12 registers the car calls of 9 floors and 14 floors at the elevator-taking place of 1 floor, the car call of 9 floors is assigned the machine C, and the car call of 15 floors is assigned the machine E, according to the assignment in fig. 7 (B). Then, the assigned car is displayed on the assigned car display unit 16 of the destination floor registration device 12 at the boarding location (step S2-7), the assignment command is output from the assignment command output unit 28 to the corresponding control unit among the control units 18a to 18X of the assigned car, and the car call registration command is output from the car call registration command output unit 26 (step S2-8).

In the case of mode 2, the machine C shares 8 layers as the destination layer, and the machine E shares 15 layers. If nothing is notified, the user may be confused as to whether the user cannot go to the desired layer.

Therefore, in step S2-6, the destination floor registration information displayed on the destination floor display unit 17 of the destination floor registration device 12 in the elevator boarding position is converted. For example, in the above example, the originally registered destination layers are: although the number C is 9 layers and the number E is 14 layers, the destination layer is changed such that the number C is 8 layers and the number E is 15 layers when sharing the responses according to the pattern 2. Then, the assigned car is displayed on the assigned car display unit 16 of the destination floor registration device 12 at the boarding location (step S2-7), the assignment command is output from the assignment command output unit 28 to the corresponding control unit among the control units 18a to 18X of the assigned car, and the car call registration command is output from the car call registration command output unit 26 (step S2-8).

In the case of "mode 2", for example, when the destination floor registration device 12 registers 14 floors as the destination floor at the elevator riding place of 1 floor, as shown in fig. 8 (C), after the destination floor is displayed as 14 floors, the E-machine is assigned as a share, and 15 floors as the destination floor after being changed from the registered destination floor are also displayed. Then, in order to draw the attention of the user, for example, "please move from floor 15 to floor 14 with the escalator is shown. "this guidance. In addition, the above-described change processing is not performed when the registered destination layer does not need to be changed.

In the case of "mode 2", after the destination floor registration device 12 is displayed at the elevator riding place of 1 floor, in order to make the user thoroughly know, for example, the user may broadcast the information by voice and display the information indicating that the destination floor is changed on a display device provided separately from the elevator riding place.

(modification example)

In the present embodiment, hall calls in the vertical direction registration device 14 installed on a floor different from the reference floor of the floor 1 or the like are handled with a car excluded from the response sharing, as in the case of the F car in fig. 7.

When the response sharing in the pattern 1 is performed, there is a possibility that the elevator hall call by the up-down direction registration device 14 may deteriorate the operation performance of the elevator. For example, when the destination floors registered by the destination floor registration device 12 at the elevator taking place of 1 floor are 8 floors and 10 floors and the car C is assigned, if the car C also responds to the hall call by the vertical direction registration device 14 at 9 floors, the number of floors to stop increases and the service decreases. In this case, the number F machine is assigned to the hall call, and the service degradation of the number C machine can be prevented.

The assignment of the response shares in the patterns 1 and 2 shown in fig. 7 is not fixed after the first determination, but the response share generation unit 22 may confirm a demand based on the number of hall call registrations registered by the hall destination registration device 12, the information on the number of hall call registrations registered by the hall destination registration device 14, and the destination floor registration information, and may appropriately change the response shares in accordance with the demand.

The data of the patterns 1 and 2 of the response shares generated by the response share generation unit 22 may be data of a plurality of different contents stored in the demand data unit 21 for each of the patterns 1 and 2, and the response share generation unit 22 may determine which of the stored response shares is used for control based on the number of hall calls registered by the hall call destination registration device 12, the information on the number of hall calls registered by the up-down direction registration device 14, and the destination information, and may respond in real time to a change in demand.

It is to be understood that the novel devices, methods and systems described in the specification can be implemented in various forms, and various omissions, substitutions and changes may be made therein without departing from the spirit of the invention.
