Description

An embodiment of the present invention relates to an elevator group management system that controls the operation of a plurality of cars.

Some elevator group control systems have a distributed standby function that keeps the cars of each elevator on standby by distributing them on each floor of the building. In this distributed standby function, in order to shorten the waiting time of passengers, it is common to distribute the cars of each car on floors with high traffic demand so that hall calls can be answered as soon as possible.

JP 2017-013983 A JP-A-11-116147

However, the above-described distributed standby function does not consider the location where the user presses the hall call button in selecting the car (car) for distributed standby. For this reason, cars that have been dispersed and waiting at a location distant from the location where the user pressed the hall call button may answer. In this case, the user has to move to the location of the car that answered the hall call, and there is a possibility that the user will miss the ride.

The problem to be solved by the present invention is an elevator that can reduce the movement of users at the hall by distributing and waiting cars in places where users frequently register hall calls at the hall. is to provide a group management system for

An elevator group management system according to an embodiment causes cars of respective elevators to wait in a distributed manner in a plurality of preset distributed standby zones. The elevator group management system includes a plurality of hall call registration devices installed at the landings of each floor, and the registration frequencies of the hall calls registered by the hall call registration devices for each of the distributed waiting zones. learning means for learning in association with the position of the hall call registration device; Distributed standby control means for selecting a machine close to a hall call registration device having a high hall call registration frequency as a distributed standby machine. The distributed standby control means selects the distributed standby elevator based on the hall call registration frequency when the hall call registration frequency in the distributed standby zone is equal to or higher than a predetermined value, and selects the hall call registration frequency. When there are a plurality of distributed standby zones having a constant value or more, the distributed standby machines are selected with priority given to the distributed standby zones in which the hall call registration frequency is high.

The disclosure is merely an example, and the invention is not limited by the contents described in the following embodiments. Modifications that can be easily conceived by those skilled in the art are naturally included in the scope of the disclosure. In order to make the explanation clearer, in the drawings, the size, shape, etc. of each part may be changed from the actual embodiment and shown schematically. Corresponding elements in multiple drawings may be denoted by the same reference numerals and detailed descriptions thereof may be omitted.

FIG. 1 is a block diagram showing the configuration of an elevator group management system according to one embodiment, and shows a configuration in which a plurality of elevators are group-controlled. The "elevator" referred to here basically means a "car". The example in FIG. 1 shows a configuration in which three elevators (cars) indicated by A, B, and C are group-controlled, but even if more elevators are group-controlled, good.

In the figure, 11a to 11c are elevator controllers (also called car controllers), and 12a to 12c are cars. The elevator control device 11a controls the operation of the car 12a of the A car. Specifically, the elevator control device 11a controls a motor (hoisting machine) (not shown) for moving the car 12a up and down, controls opening and closing of doors, and the like. The same applies to the elevator control device 11b for the B car and the elevator control device 11c for the C car. These elevator control devices 11a to 11c are composed of computers equipped with CPU, ROM, RAM and the like.

The cars 12a to 12c move up and down in the hoistway by being driven by a motor (winding machine). A car operation panel 13a having various operation buttons including a destination floor button, a door open button, a door close button and the like is installed in the interior of the car 12a. These button signals are transmitted to the group supervisory control device 30 via the elevator control device 11a of car A.

Similarly, in the interior of the car 12b, a car operating panel 13b having various operation buttons including a destination floor button, a door open button, a door close button and the like is installed. These button signals are transmitted to the group supervisory control device 30 via the elevator control device 11b of the B car. A car operation panel 13c having various operation buttons including a destination floor button, a door open button, a door close button and the like is installed in the interior of the car 12c. The signals of these buttons are transmitted to the group supervisory control device 30 via the elevator control device 11c of the C car.

Hall call buttons 21a, 21b, and 21c are installed at the hall (elevator hall) as registration devices for users to register hall calls. The number of hall call buttons can be arbitrarily determined in consideration of the number of cars. In this embodiment, it is assumed that hall call buttons 21a, 21b, and 21c are installed for each car, as in the example of FIG. In practice, hall call buttons 21a, 21b, and 21c are installed for each car at the boarding area of each floor.

The hall call buttons 21a, 21b, 21c are composed of an upward button and a downward button, and are configured such that the upward button or the downward button is pressed according to the destination direction (upward/downward) of the user. ing. Note that the bottom floor has only an upward button, and the top floor has only a downward button.

A "hall call" is a call signal that is registered by operating a hall call button installed at the boarding area of each floor. downward direction), and button information (information on the hall call button pressed by the user). A "car call" is a call signal that is registered by operating a destination floor button provided in the car room, and includes information about the destination floor and car number.

The group supervisory control device 30 is a device for group-supervisedly controlling the operation of the car of each car, and is composed of a computer having a CPU, a ROM, a RAM, etc., like the elevator controllers 11a to 11c. In this embodiment, the group supervisory control device 30 is provided with a state monitoring section 31 , a distributed zone setting section 32 , a call storage section 33 , a learning section 34 and a distributed standby control section 35 . These processing units are actually realized by software or a combination of software and hardware.

The state monitoring unit 31 monitors the operating state (car position, driving direction, door open/closed state, etc.) of the cars 12a to 12c of each car. The distributed zone setting unit 32 sets a plurality of zones (distributed standby zones) for keeping the cars 12a to 12c of each car on standby. The distributed waiting zone consists of at least two floors, and is set at a plurality of locations between the lowest and highest floors in consideration of the number of cars, the number of floors of the building, traffic demand, etc. (see FIG. 3).

The call storage unit 33 stores hall calls registered by operating hall call buttons 21a, 21b, and 21c installed at the hall of each floor. The learning unit 34 learns the registration frequency of hall calls registered on each floor in association with the position of the hall call button for each of a plurality of preset distributed waiting zones. The hall call registration frequency is obtained from the number of times the user presses the hall call button at the hall. Which hall call button on which floor the user has pressed can be determined from the hall call information registered in the call storage unit 33 .

Based on the hall call registration frequency learned by the learning unit 34, the distributed standby control unit 35 selects a car number close to the hall call button with a high hall call registration frequency as a distributed standby car, and performs each distributed standby car at a predetermined timing. Distributed standby in the standby zone.

Here, "a hall call button with a high hall call registration frequency" refers to a hall call button whose hall call registration frequency is higher than the average value of the hall call registration frequency in the distributed waiting zone. .A hall call button with a registration frequency of 3 times or more. The "predetermined timing" is when the car is in a waiting state after the user gets off at an arbitrary floor, that is, when the car stops after the driving service is completed.

The group supervisory control device 30 has an allocation control function as a basic function. When a new hall call is registered, this function selects a car to which the hall call is to be assigned using a predetermined allocation evaluation method, and responds to the registered floor of the hall call using that car as the assigned car. is. As the allocation evaluation method, for example, there is an RTS (Real Time Scheduling) method, etc., but since it is not directly related to the present invention, the description thereof will be omitted here.

FIG. 2 is a diagram showing an example of a hall call installed at a hall.
In the figure, 20 is a landing on an arbitrary floor, and 22a, 22b, and 22c are hold doors. In the example of FIG. 2, the hall call button 21a is located at one end of the hold door 22a of car A (on the right side as viewed), the hall call button 21b is located at one end of the hold door 22b of car B, and the one end of the hold door 22c of car C is shown. is provided with a hall call button 21c. When a user who has come to the hall 20 presses one of the hall call buttons 21a, 21b, and 21c, the hall call for the relevant floor is registered in the call storage unit 33 of the group control device 30, and any one of the cars A to C is registered. That car answers the landing 20 of that floor.

FIG. 3 is a diagram showing an example of distributed waiting.
In the example of FIG. 3, in a building with 20 floors, the "2nd and 3rd floors" are the distributed waiting zone Z1, the "9th and 10th floors" are the distributed waiting zone Z2, and the "19th and 20th floors" are the distributed waiting zones. It is set as Z3. The number of distributed waiting zones and the number of floors in each zone are arbitrarily set in consideration of the number of cars, the number of floors of the building, traffic demand, etc., and are limited to the example shown in Fig. 3. isn't it.

In the normal distributed standby function, regardless of the hall call registration frequency, the car of each car that has completed the operation service moves to a nearby floor in the distributed waiting zone and waits. For example, when the car 12a of the A car finishes the driving service on the 4th floor, it moves to the 3rd floor in the distributed waiting zone Z1 near the 4th floor and waits. When the car 12b of the B car finishes the driving service on the 7th floor, it moves to the 7th floor in the distributed waiting zone Z2 near the 6th floor and waits there. Also, like the car 12c of the C car, when the driving service is finished on the 20th floor in the distributed waiting zone Z3, the car will wait there.

In this way, by moving a car that has finished driving service to a distributed waiting zone, it is possible to respond immediately when a new hall call is registered in the distributed waiting zone. However, in the normal distributed waiting function, the location (button position) where the user registers the hall call is not taken into consideration when selecting the cars to be placed in distributed waiting. For this reason, a car far from the place where the user registered the hall call may answer.

For example, in the building shown in FIG. 3, it is assumed that users are likely to gather near the hall call button 21c installed near the C-car in the hall on the third floor. In normal distributed waiting, the car 12c of Car C is not necessarily waiting in a distributed manner at the hall on the 3rd floor. , the car 12a of car A, which is distant from car C, may respond. In such a case, the user must move from the C-machine to the A-machine.

Therefore, in the present embodiment, the registration frequency of hall calls registered by each hall call button in the distributed waiting zone is learned, and a car corresponding to a car close to the hall call button with a high hall call registration frequency is selected. It has a distributed standby configuration.

FIG. 4 is a diagram showing an example of the learning table T1 provided in the learning section 34. As shown in FIG.
In the learning table T1, the registration frequency of hall calls registered on each floor for each distributed waiting zone is stored in association with the position of the hall call button. B31, B32, and B33 in the drawing indicate the positions of hall call buttons 21a, 21b, and 21c installed in the hall on the third floor. B21, B22, and B23 indicate the positions of hall call buttons 21a, 21b, and 21c installed at the landing on the second floor. B101, B102 and B103 indicate the positions of hall call buttons 21a, 21b and 21c installed at the tenth floor hall. B91, B92, and B93 indicate the positions of hall call buttons 21a, 21b, and 21c installed in the hall on the ninth floor. B31, B21, B101, B91 are near the platform (boarding gate) of aircraft A, B32, B22, B102, B92 are near the platform (boarding gate) of aircraft B, B33, B23, B103, B93 are near the platform (boarding gate) of aircraft C It is near the (boarding gate).

The example in FIG. 4 shows part of the learning results for an arbitrary day of the week and time period. For example, during the time period from 8:00 to 9:00 on Monday, on the 3rd floor of the distributed waiting zone Z1, the registration frequency (the number of ) is 100. Also, the registration frequency of the hall call registered by the hall call button 21b installed near the boarding place of the car B and the registration frequency of the hall call registered by the hall call button 21c installed near the boarding place of the car C are also 100. be. In practice, for each of the distributed waiting zones Z1, Z2 and Z3, the relationship between the hall call registration frequency and the button position is learned for each day of the week and time zone.

Next, the operation of this embodiment will be described.
FIG. 5 is a flow chart showing the operation of the elevator group management system in this embodiment. The processing shown in this flowchart is executed by the group supervisory control device 30, which is a computer.

It is now assumed that three cars 12a, 12b, and 12c indicated by cars A to C are in operation. During operation of each elevator, the learning unit 34 provided in the group supervisory control device 30 collects the hall call registration frequency for each floor in the dispersed waiting zones Z1, Z2, and Z3 shown in FIG. It is learned in association with the position of the hall call button above (step S11).

The distributed standby control unit 35 determines whether or not the current time zone is a time zone with few users (step S12). For example, in the case of an office building, the "time zone with few users" means a time zone other than the working hours, lunch hours, and leaving hours. It is assumed that the distributed standby control unit 35 is preset with a time zone with few users (off-peak time zone) and a time zone with many users (congested time zone) according to the traffic demand of the building.

Here, since operation efficiency is prioritized during times when there are many users, cars that have finished driving service are distributed and waited in the nearest distributed waiting zone as soon as possible, and a system that allows immediate response to new hall calls. should be arranged. Therefore, when it is a time zone with many users (No in step S12), the distributed standby control unit 35 causes the cars 12a, 12b, and 12c of each car to finish the operation service by normal distributed standby processing. When they are ready, they are made to wait in distributed waiting zones close to each other (step S16).

On the other hand, if it is a time zone with few users (Yes in step S12), the distributed standby control unit 35 targets the distributed standby zones that satisfy the following conditions, and distributes the hall call registration frequency in consideration of the hall call registration frequency. Execute standby processing.

That is, first, the distributed standby control unit 35 reads out the learning table T1 corresponding to the same day of the week and the same time period as the current one from the learning unit 34, and the registration frequency of hall calls (the total number of hall calls) in the distributed standby zone is constant. It is determined whether or not there is a distributed standby zone with a value of K1 or more (step S13). The value of K1 is, for example, the average of hall call registration frequencies in the distributed waiting zone.

In the example of the learning table T1 shown in FIG. 4, the registration frequency of hall calls on the third floor of the distributed waiting zone Z1 is 300 (100+100+100), and the registration frequency of hall calls on the second floor is 180 (100+30+50). Therefore, the hall call registration frequency (the total number of hall calls) of the distributed waiting zone Z1 is 480. On the other hand, the registration frequency of hall calls on the 10th floor of the distributed waiting zone Z2 is 150 (50+50+50), and the registration frequency of hall calls on the 9th floor is 80 (30+20+30). Therefore, the hall call registration frequency (the total number of hall calls) of the distributed waiting zone Z2 is 230. For example, if K1 is set to 300, the distributed standby zone Z1 satisfies the condition that the constant value K1 or more.

If there is a distributed waiting zone that satisfies a condition equal to or greater than the constant value K1 (Yes in step S13), the distributed standby control unit 35 sets the hall call registration frequency to the constant value K2 depending on the position of the hall call button in the distributed standby zone. It is determined whether or not there is the above difference (step S14). The value of K2 is arbitrarily set in consideration of the traffic demand at the boarding point of the relevant floor. For example, if K 2 is set to 50, the second floor of the distributed waiting zone Z1 corresponds.

If there is a difference of the predetermined value K2 or more in the hall call registration frequency depending on the position of the hall call button (Yes in step S14), the distributed standby control unit 35 selects a hall call having a high hall call registration frequency in the distributed standby zone. A car close to the button is selected as a distributed standby car, and when the car corresponding to the distributed standby car finishes the operation service, it is placed in a distributed standby (step S15).

As described above, "a hall call button with a high hall call registration frequency" is a hall call button with a higher hall call registration frequency than the average value in the distributed waiting zone. If there are a plurality of hall call buttons with a high hall call registration frequency in the distributed waiting zone that satisfies the above constant value K2 or more, the hall call button with the highest registration frequency is selected and assigned to that hall call button. A nearby machine shall be selected as a distributed stand-by machine. The distributed standby control unit 35 sets the floor with the highest hall call registration frequency in the distributed standby zone as the distributed floor, and moves the car selected as the distributed standby elevator to the distributed floor.

On the other hand, in step S13, if there is no distributed waiting zone that satisfies the constant value K1 or more, the distributed waiting control unit 35 performs normal distributed waiting processing for the cars 12a, 12b, and 12c of each car. have finished the driving service, they are made to wait in distributed standby zones close to each other (No in step S13→S16). The same applies when there is no distributed standby zone that satisfies the constant value K2 or more in step S14, and the distributed standby control unit 35 performs normal distributed standby processing (No in step S14 → No in step S14). step S16).

In step S13, if there are a plurality of distributed standby zones that satisfy the condition of the constant value K1 or more, the distributed standby control unit 35 selects the distributed standby zone with a high hall call registration frequency (total number of hall calls). First, a distributed standby machine is selected (steps S14-S15).

Next, it demonstrates using a specific example.
(Example 1) When there is a difference in the registration frequency of hall calls depending on the button position FIG. 6 is a diagram showing an example in which the registration frequency of hall calls differs depending on the button position.
Assume now that the second and third floors are set as a distributed waiting zone Z1, and the hall call buttons 21a, 21b, and 21c are arranged as shown in the example of FIG. The numbers in the figure indicate the registration frequency (number of registrations) of hall calls with respect to button positions. The registration frequency of hall calls (the total number of hall calls) in the distributed waiting zone Z1 is 300 (100+100+100)+180 (100+30+50)=480, which satisfies the condition of the constant value K1.

In example 1, since there is a difference of the predetermined value K2 or more in the hall call registration frequency on the second floor of the distributed waiting zone Z1, this system of distributed waiting is executed. In this case, the third floor with the largest number of registered hall calls in the distributed waiting zone Z1 is determined as the distributed floor. Further, when viewed from the hall call registration location in the hall, the registration frequency of the hall call button 21a is high within the distributed waiting zone Z1. Therefore, the car 12a of the A car near the hall call button 21a is selected as the distributed standby car, and when the car 12a finishes the driving service, it moves to the third floor and waits there.

(Example 2) When there is no difference in the registration frequency of hall calls depending on the button position FIG. 7 is a diagram showing an example when there is no difference in the registration frequency of hall calls depending on the button position.
Assume now that the second and third floors are set as a distributed waiting zone Z1, and the hall call buttons 21a, 21b, and 21c are arranged as shown in the example of FIG. The numbers in the figure indicate the registration frequency (number of registrations) of hall calls. It is assumed that the registration frequency of hall calls (total number of hall calls) in the distributed waiting zone Z1 is 140 (50+50+40)+170 (60+50+60)=310, which satisfies the condition of the constant value K1.

In Example 2, normal distributed waiting is performed because there is no difference of the predetermined value K2 or more in the hall call registration frequency between the second floor and the third floor of the distributed waiting zone Z1. In this case, the second floor with the largest number of registered hall calls in the distributed waiting zone Z1 is determined as the distributed floor. In this case, the distributed waiting car is not specified, and the car corresponding to the car among the cars A, B, and C that has finished the service moves to the second floor and waits there.

For the distributed waiting zone with the second highest hall call registration frequency (the total number of hall calls) in the distributed waiting zone, in the case of example 1, a distributed waiting machine other than the A car is selected. For the second and subsequent distributed standby zones, when the conditions of the constant values K1 and K2 are satisfied, a distributed standby machine suitable for the zone is selected from the machines that are not determined as distributed standby machines in other distributed standby zones. be. If the conditions of the constant values K1 and K2 are not satisfied, the cars of the elevator cars that are not determined as the distributed standby cars in the other distributed standby zones will be in distributed standby by normal distributed standby. Also, as in Example 2, in the distributed standby zone where a specific distributed standby car is not determined, the cars of the cars that are not determined as distributed standby cars in other distributed standby zones are on standby in a distributed manner.

As described above, according to the present embodiment, based on the relationship between the position of the hall call button at the hall and the registration frequency of the hall call, among the cars, the cars close to the hall call button with the high hall call registration frequency are distributed. Selected as a standby machine. Therefore, it is possible to reduce the movement of the users at the hall by dispersing and waiting the cars in places where the frequency of hall call registration by the users is high.

(Modification)
(1) Re-dispersed standby When a car selected as a distributed standby elevator is placed in distributed standby, the car of another elevator may be abandoned on a floor within the corresponding distributed standby zone and be in a standby state. In such a case, it is preferable to wait the car of the other car on the floor for a predetermined time, and then call back the original car selected as the distributed standby car to the floor and wait in a distributed manner. .

Specifically, for example, as shown in FIG. 8, the 3rd floor in the distributed standby zone Z1 is determined as the distributed standby floor, and the car 12a of the A-type car is designated as the distributed standby elevator for the boarding area on the 3rd floor. Suppose you were elected. At this time, if the car 12c of the C car is abandoned on the 3rd floor, it is better to use the car 12c of the C car as a distributed waiting car so that it can respond immediately when there is a hall call on the 3rd floor. convenient. However, in terms of hall call registration frequency, by keeping the car 12a of car A on standby in a distributed manner, it is possible to reduce the movement of users. Pull back 12a on the 3rd floor and wait.

FIG. 9 is a flow chart showing processing of waiting for redistribution as Modification 1 above. The process of this flow chart is executed after the distributed standby machines are selected in step S15 of FIG.

In step S15 of FIG. 5, when a distributed standby car is selected, the distributed standby control unit 35 confirms the operating status of the cars 12a to 12c of each car through the state monitoring unit 31. FIG. As a result, when the car of another elevator is abandoned on the floor in the dispersed standby zone set as the dispersed standby destination of the relevant dispersed standby elevator and is in a standby state (Yes in step S21), the dispersed standby The control unit 35 causes the cars of the other cars to stand by on the floor for a predetermined time (for example, 10 minutes) (step S22).

In the example of FIG. 8, the car 12c of car No. C corresponds to this, and is kept waiting on the 3rd floor for a predetermined time. If a new hall call is registered on the third floor during this time, the car 12c of car No. C will answer.

After a predetermined period of time has passed, the distributed standby control unit 35 pulls back the original distributed standby elevator to the floor within the set distributed standby zone and puts it in distributed standby (step S23). That is, in the example of FIG. 8, the car 12a of car A is pulled back to the 3rd floor and placed on standby. At this time, if the car 12c of the C car has been selected as a distributed standby car in another distributed standby zone, after the predetermined time has passed, the car 12c of the C car will be replaced with the car 12 of the A car. to a floor within the above-mentioned other distributed waiting zone.

In this way, when a car of another car is abandoned on a floor within the distributed waiting zone, by making the car wait on that floor for a predetermined period of time, when a hall call is registered on that floor, It can respond immediately and shorten the waiting time of the user.

(2) Adjustment of the Number of Distributed Standby Machines In the above embodiment, one machine is placed on standby in each distributed standby zone. It is also possible to adjust the number of cars).

For example, when the standard floor is included in the distributed waiting zone, if both the leftmost hall call button registration frequency and the rightmost hall call button registration frequency are high in a certain time period, selects two cars as distributed standby cars, and puts cars corresponding to each car on standby. However, it is preferable to execute this when the number of cars is larger than the number of distributed standby zones, because the number of cars to be distributedly standby in other distributed standby zones may be insufficient.

(3) Shared button In the above embodiment, the explanation was given on the assumption that one hall call button is arranged for each car at the hall (see FIG. 2), but for example, as shown in FIG. It is sometimes installed as a shared button near the middle between two adjacent cars at the boarding hall.

In the example of FIG. 10, a hall call button 41a is placed between the hold door 22a of car A and the hold door 22b of car B, and a hall call button 41b is placed between the hold door 22c of car C and the hold door 22d of car D. is set up. In such a case, the hall call registered by the hall call button 41a is learned by the learning unit 34 as a hall call registered between the A and B machines. Similarly, the hall call registered by the hall call button 41b is learned by the learning unit 34 as a hall call registered between the C car and the D car.

Here, for example, when the hall call button 41a is registered frequently and the cars near the hall call button 41a are selected as distributed standby cars, the cars A and B are candidates. In this case, the distributed standby control unit 35 preferentially selects, as a distributed standby machine, one of the A- and B-machines that can be put on a distributed standby earlier. For example, when the car 12a of the A car finishes the operation service earlier than the car 12b of the B car, the distributed standby control unit 35 preferentially selects the A car as the distributed standby car.

(4) User Detection In the above embodiment, the number of times the hall call button is pressed by the user is learned as the registration frequency of the hall call in association with the position of the hall call button. As another method, it is also possible to detect the number of users who operate the hall call button, and learn the number of detected users as the hall call registration frequency in association with the position of the hall call button.

Specifically, for example, as shown in FIG. 11, a camera 42 is installed at the hall 20 of each floor, and by analyzing the image taken by this camera 42, the hall call buttons 21a, 21b, and 21c are pressed. Users and their number are detected by button position. The image analysis device may be provided independently from the group supervisory control device 30 at the landing 20 on each floor, or may be provided inside the group supervisory control device 30 .

Further, as shown in FIG. 12, human sensors 43a, 43b, and 43c are provided near the hall call buttons 21a, 21b, and 21c, and the users who pressed the hall call buttons 21a, 21b, and 21c and their number are detected by buttons. It is also possible to detect by location. The human sensor 43a detects a user who has come near the hall call button 21a.
