Description

Elevator control device and method, elevator group management control device and elevator system

Technical Field

Embodiments of the present invention relate to an elevator control device, an elevator group management control device, an elevator system, and an elevator control method.

Background

Conventionally, when a call is made at an elevator hall registered, a car assigned to the hall call is answered. At this time, when the car is full before reaching the response floor called by the elevator hall, the car cannot be overtaken, and therefore the car passes without stopping at the response floor (hereinafter, such passage of the response floor is referred to as "full passage").

At this time, whether or not the car is full is determined by whether or not the load amount applied to the car reaches a predetermined value, and therefore, if the load amount does not reach the predetermined value although the car is crowded, the car stops at the response floor and opens the door.

However, when the car stops and the door is opened, depending on the users, the car may be left without getting in if the car is crowded to some extent. If such a situation occurs, the operation efficiency of the elevator decreases.

Detailed Description

EXAMPLE 1 embodiment

< construction of Elevator System of embodiment 1 >

A configuration of an elevator system 1A using an elevator group control device according to embodiment 1 of the present invention will be described with reference to fig. 1. The elevator system 1A of the present embodiment includes: an X elevator 10X and a Y elevator 10Y provided in a building of n floors; elevator-taking place operation panels 21-1 to 21-n and camera devices 22-1 to 22-n as user identification devices, which are respectively arranged at elevator-taking places 20-1 to 20-n of 1 to n floors in the building; and an elevator group management control device 30A for performing group management control on the X elevator 10X and the Y elevator 10Y. In the present embodiment, the camera device is used as the user identification device, but the present invention is not limited to this, and any device may be used as long as it can identify the user, such as an authentication device that uses information acquired from a portable terminal, a card key, an ID tag, or the like that the user carries.

The X-machine elevator 10X includes: an individual control device 12X for an elevator with an elevator car 11X, X, and landing doors 13X-1 to 13X-n provided at landing places 20-1 to 20-n of each floor. An in-car operation panel 111X for a user to perform a floor-to-floor registration operation is provided in the car 11X. The Y-type elevator 10Y also has a single elevator controller 12Y of the car 11Y, Y and landing doors 13Y-1 to 13Y-n, and an in-car operating panel 111Y is provided in the car 11Y.

Hereinafter, the elevator 10 is simply described as the elevator 10 when it is not necessary to specify the X-machine elevator 10X or the Y-machine elevator 10Y. Similarly, each device in the elevator is also described as a car 11, an elevator individual control device 12, an in-car operation panel 111, and a landing door 13.

The individual X-machine elevator control device 12X transmits the destination floor registration operation information on the in-car operation panel 111X, the load information applied to the car 11X, the position information of the car 11X, the traveling direction information, and the like to the elevator group management control device 30A. Further, the operation of the machine in the X-machine elevator 10X is controlled based on an instruction from the elevator group management control device 30A.

Similarly, the individual Y-elevator control device 12Y transmits the destination floor registration operation information on the in-car operation panel 111Y, the load information applied to the car 11Y, the position information of the car 11Y, the traveling direction information, and the like to the group control device 30A. Further, the operation of the machine in the Y-machine elevator 10Y is controlled based on an instruction from the group management control device 30A.

The elevator-taking operation panels 21-1 to 21-n of the elevator-taking places 20-1 to 20-n are respectively provided with a key for a user to designate an upward direction or a downward direction for call registration at the elevator-taking place. The camera devices 22-1 to 22-n of the elevator riding places 20-1 to 20-n respectively take images of the elevator riding places 20-1 to 20-n of the floors on which the camera devices are installed, and acquire identification information of users located at the corresponding elevator riding places 20-1 to 20-n from the generated image information.

As shown in fig. 2, the elevator group management control device 30A includes: a specification information storage section 301, an elevator information management section 302A, a waiting start time acquisition section 303, an occupancy determination information output section 304A, an occupancy determination database 305, an occupancy call reception section 306, an assignment evaluation value calculation section 307, an assigned car determination section 308, an occupancy determination information acquisition section 309, a user allowable occupancy rate calculation section 310A, an occupancy allowable occupancy rate calculation section 311, and a control command output section 312.

The specification information storage 301 stores in advance specification information related to the X-machine elevator 10X and the Y-machine elevator 10Y, such as the use application, the members of the cars 11X and 11Y, and the rated speed. These pieces of information can also be acquired from the individual elevator control device 12Y of elevator No. X12X, Y. The elevator information management unit 302A acquires the operating condition information of the X elevator 10X and the Y elevator 10Y from the X elevator individual control device 12X, Y elevator individual control device 12Y. The operating condition information includes, for example, destination floor registration operation information on the in-car operation panels 111X and 111Y, load information applied to the cars 11X and 11Y, position information and traveling direction information of the cars 11X and 11Y, and the like.

The waiting start time acquisition unit 303 acquires the time at which the identification information of the user is acquired by the camera devices 22-1 to 22-n as the elevator waiting start time of each user at each elevator hall 20-1 to 20-n at each floor. The boarding determination information output unit 304A acquires, as boarding determination information, the waiting time from the waiting start time to the door opening of each user located at each of the cars 11X and 11Y, information indicating whether or not the car 11X and 11Y has been boarded and the minimum boarding rate during the door opening of the corresponding car 11X and 11Y, every time the car 11X and 11Y is opened at a certain car 20, based on the information acquired by the elevator information management unit 302A and the elevator waiting start time of each user acquired by the waiting start time acquisition unit 303, and outputs the boarding determination information to the boarding determination database 305. The occupancy determination database 305 stores the occupancy determination information of each user output from the occupancy determination information output unit 304A.

The boarding area call receiving unit 306 receives boarding area call information based on the operation of the boarding area operation panels 21-1 to 21-n for each floor. When a new hall call is received by the hall call receiving unit 306, the assignment evaluation value calculation unit 307 calculates an evaluation value indicating the priority of assignment of each of the cars 11X and 11Y to the hall call based on the operating condition information of the X-elevator 10X and the Y-elevator 10Y acquired by the elevator information management unit 302A. The assigned car determination unit 308 determines an assigned car for the elevator riding place call based on the evaluation value calculated by the assigned evaluation value calculation unit 307.

When a new hall call is received by the hall call receiving unit 306, the boarding determination information acquiring unit 309 acquires, from the boarding determination database 305, boarding determination information related to a user who has acquired identification information from the camera device 22 installed on the floor on which the hall call has occurred.

The user's allowable riding rate calculation unit 310A acquires the predicted arrival time of the car 11, which responds to the new riding department call received by the riding department call receiving unit 306, from the elevator information management unit 302A. The predicted waiting time of each user at the corresponding elevator riding place is calculated based on the elevator waiting start time of each user at the corresponding elevator riding place acquired by the waiting start time acquisition unit 303 and the acquired predicted arrival time of the car 11. Further, based on the information acquired by the boarding determination information acquisition unit 309, a permitted boarding rate table indicating the upper limit value of the boarding rate of permitted boarding (hereinafter referred to as "permitted boarding rate") for each user who is located on the floor where the elevator boarding call has occurred and each waiting time is generated. Then, the allowable riding rate of each user on the corresponding floor to the corresponding car 11 is calculated based on the generated allowable riding rate map and the calculated predicted waiting time of each user. The riding-place permitted riding rate calculating unit 311 calculates the permitted riding rate for the riding place 20 based on the permitted riding rate of each user calculated by the user permitted riding rate calculating unit 310A.

The control command output unit 312 outputs a response command to the hall call to the individual elevator control device 12 corresponding to the car 11 assigned by the assigned car determination unit 308. The control command output unit 312 determines whether or not the occupancy of the car 11 allocated by the allocated-car determining unit 308 exceeds the allowable riding rate of the riding place 20 calculated by the riding place allowable riding rate calculating unit 311, based on the information acquired by the elevator information managing unit 302A. When the determined result is that the riding rate of the car 11 exceeds the allowable riding rate of the riding place 20, an instruction for allowing the car 11 to pass through without stopping at the riding place 20 is output to the corresponding individual elevator control device 12.

< operation of the elevator system according to embodiment 1 >

Next, as an example of the operation of the elevator system 1A according to the present embodiment, the processing executed when the user a of the elevator arrives at the boarding location 20-1 at floor 1, (1) the processing of learning the usage tendency of the user, (2) the boarding location call assignment processing, and (3) the determination processing of full passage will be described.

(1) Processing for learning utilization tendency of user

The processing executed by the elevator system 1A to learn the usage tendency of each user will be described with reference to the time chart of fig. 3. First, the elevator information management unit 302A of the elevator group management control device 30A acquires information on the members of the car 11X of the X-elevator 10X and the car 11Y of the Y-elevator 10Y from the specification information storage unit 301 (S1). Further, the operation condition information of the X elevator 10X, Y elevator 10Y is acquired from the X elevator individual control device 12X, Y elevator individual control device 12Y at predetermined time intervals. The operating condition information of the X elevator 10X, Y, i.e., the elevator 10Y, includes load information of the car 11X and the car 11Y. When the operating condition information is acquired by the elevator information management unit 302, the riding rates of the cars 11X and 11Y are calculated based on the information on the occupants of the cars 11X and 11Y and the load information (S2).

When the user a of the elevator arrives at the elevator-riding place 20-1 on floor 1, the camera device 22-1 acquires the identification information of the user a from the shot information. The identification information of the user a acquired by the camera device 22-1 is transmitted to the elevator group management control device 30A.

In the elevator group control device 30A, the waiting start time acquisition unit 303 and the boarding determination information output unit 304A acquire the identification information of the user a at the boarding location 20-1 transmitted from the camera device 22-1. The waiting start time acquisition unit 303 starts measurement of the waiting time for the user a to wait for the elevator at the boarding area 20-1. The measurement of the waiting time of the elevator may be started at the timing (timing) when the identification information of the user a is acquired, or may be started at the timing when the elevator hall call is operated by the elevator hall operation panel 21-1 after the identification information of the user a is acquired.

When the user a operates the boarding area operation panel 21-1 to make a boarding area call and either of the cars 11X and 11Y stops at the boarding area 20-1 in response to this and opens the door, the time from the start of measurement of the waiting time of the user a to the opening of the door of the car is acquired as the waiting time of the user a and is output to the boarding determination information output unit 304A (S3).

When the information on the waiting time of the user a is acquired from the waiting start time acquisition unit 303, the riding determination information output unit 304A acquires the minimum riding rate of the corresponding car 11 during the door opening period from the elevator information management unit 302A. The minimum riding rate of the car 11 during the door opening period is obtained as the riding rate of the car 11 at the time point when it is determined whether the user a has ridden. In addition, information indicating whether or not the user a has taken the car 11 is acquired by whether or not the load amount applied to the car 11 increases during the door opening period or by analysis processing of the shot information by the camera device 22-1 (S4).

Then, the waiting time of the user a, the minimum occupancy rate during the door opening period of the car 11, and information indicating whether or not the user a has taken the car 11 after the door opening are acquired as the taking judgment information and output to the taking judgment database (S5). In this way, every time the car 11X, 11Y opens the door at a certain elevator hall 20, the boarding judgment information corresponding to each user located at the elevator hall 20 is acquired and output to the boarding judgment database 305. The boarding determination information of each user outputted from the boarding determination information output unit 304A is sequentially stored in the boarding determination database 305, whereby the past elevator usage status can be stored (S6).

Fig. 4 shows an example of the occupancy determination information stored in the occupancy determination database 305. Fig. 4 shows the waiting time stored for each time the user A, B … … Z waits for an elevator to be used at a certain elevator hall 20, the minimum riding rate during the door opening period of the car 11, information indicating whether the user a has taken the car 11 after the door opening, and the date and time of recording the information. For example, the user a rides on the car 11 with a riding rate of 30% when 10 minutes 32 seconds are provided at 5/30/9/2015 and the waiting time is 4 seconds.

Since the storage capacity of the occupancy determination database 305 is limited, the existing information is overwritten with new information as necessary. For example, it is assumed that: when the recordable number of users is set to 26 and the number of pieces of information storable for each user is set to 10, the occupancy determination database 305 already stores the occupancy determination information of 26 persons of the users a to Z including 10 pieces of occupancy determination information on the user a and 6 pieces of occupancy determination information on the user B.

In this state, when new occupancy determination information a concerning the user a is acquired, the occupancy determination information having the same waiting time as the waiting time "4 seconds" indicated by the occupancy determination information a among the existing information of the user a is overwritten with the new occupancy determination information a. If there is no existing occupancy determination information with the same waiting time among the existing information of the user a, the oldest occupancy determination information of the user a is overwritten with the new occupancy determination information a. Here, if the waiting time is compared with a value divided in a short time such as 1 second, the probability that the waiting time of new information matches the waiting time of existing information is considerably low, and therefore, the comparison may be performed with a value divided in a unit of 5 seconds, for example.

When the occupancy determination information AA of the new user AA is acquired, the information of the oldest user whose latest update date and time is earlier than a predetermined period (for example, years or months) is erased from the existing information, and the information of the new user AA is stored. If there is no user information of a user whose last update date is earlier than a predetermined period in the existing information, the user B with the least amount of information recorded is regarded as a temporary user with a low frequency of use, and the information AA of the new user AA is stored while erasing the corresponding information. However, if information of a user with a small amount of information is erased, if the occupancy determination database 305 is used in a building whose storage capacity is insufficient for the number of frequently used users, the information of a new user is frequently erased immediately after being stored, and there is a high possibility that it is difficult to continuously store the information. Therefore, even when information of a user with a small amount of information is erased, a slight error may be detected and information urging expansion of the storage capacity may be reported.

(2) Call assignment handling at elevator ride

The hall call allocation process executed in the elevator system 1A in parallel with the process of learning the usage tendency of the user (1) when the user a of the elevator arrives at the hall 20-1 at floor 1 will be described with reference to the sequence chart of fig. 5.

When the user a who has arrived at the boarding location 20-1 performs a call registration operation on the boarding location operation panel 21-1, the user a is received by the boarding location call receiving unit 306 of the elevator group management control device 30A. The information of the accepted elevator boarding completion call is output to the assignment evaluation value calculation unit 307 and the boarding determination information acquisition unit 309 (S11).

When the information of a new hall call is acquired from the hall call receiving unit 306, the assignment evaluation value calculation unit 307 calculates an evaluation value indicating the assignment priority of each of the cars 11X and 11Y to the hall call based on the operating condition information of the X-elevator 10X and the Y-elevator 10Y acquired by the elevator information management unit 302A. The evaluation value of each car 11X, 11Y is a value for evaluating which car 11 a newly registered car call should be assigned to, and for example, a higher value is calculated as the predicted arrival time of each car at the corresponding car 20 is earlier. The information of the calculated evaluation value is output to the assigned car determination unit 308(S12, S13).

The assigned car determination unit 308 determines an assigned car to call the elevator riding place based on the evaluation value calculated by the assigned evaluation value calculation unit 307. Here, the car 11X is determined as an assigned car. The information of the determined assigned car 11X is output to the control command output unit 312 and the user allowable occupancy rate calculation unit 310A (S14).

The control command output unit 312 outputs a response command for the hall call to the individual elevator control device 12X corresponding to the car 11X determined as the assigned car (S15). This concludes the description of the call assignment process at the elevator boarding location.

(3) Judgment processing of full member passing

As described above, the process of determining the full passenger passage performed when a new hall call is registered will be described with reference to the sequence chart of fig. 5.

When the information of the hall call is output from the hall call receiving unit 306, the boarding determination information acquiring unit 309 acquires the identification information of the user located at the hall 20-1 from the camera device 22-1 of the floor 1 where the hall call has occurred. Here, it is assumed that identification information of 5 persons, i.e., users a to E, which are users located at the elevator hall 20-1, is acquired. Then, the occupancy determination information on the users a to E is acquired from the occupancy determination database 305. Here, the user who has not stored the occupancy determination information because of first using the building uses the average occupancy determination information created in advance. The acquired riding determination information of the users a to E is output to the user allowable riding rate calculation unit 310A (S16).

The user's allowable riding rate calculation unit 310A obtains the predicted arrival time of the car 11X, which has responded to the new hall call, from the elevator information management unit 302A. Then, the predicted waiting time of each of the users a to E at the corresponding boarding location 20-1 is calculated based on the elevator waiting start time of each of the users a to E at the corresponding boarding location 20-1 acquired by the waiting start time acquisition unit 303 and the acquired predicted arrival time of the car 11X (S17). Further, based on the information acquired by the boarding determination information acquisition unit 309, a tolerable boarding rate table indicating the tolerable boarding rate at each waiting time is generated for each of the users a to E of the boarding location 20-1 for which the boarding location call has occurred.

The process of creating the allowable occupancy rate table will be described with reference to fig. 6. First, as shown in fig. 6(a), a graph is created for each user with the horizontal axis representing the waiting time and the vertical axis representing the occupancy rate of the car, and o marks are drawn at positions corresponding to the waiting time and the occupancy rate when the user has occupied the car during the past use, and x marks are drawn at positions corresponding to the waiting time and the occupancy rate when the user has not occupied the car. Next, from the graph of fig. 6(a), a curve indicating the boundary between the region where the o mark is drawn and the region where the x mark is drawn is obtained as shown in fig. 6(b), and an allowable riding rate graph indicating the riding rate related to the user is generated. The allowable riding rate table is created for each of the users a to E located at the boarding area 20-1.

In the acceptable riding rate table shown in fig. 6(b), it is considered that the longer the waiting time is, the higher the acceptable riding rate tends to be. It is also considered that the probability of a user at the upper end of the graph riding in the car is high even if the riding rate is high, and the probability of a user at the lower end waiting for a long time before the empty car 11 arrives is high.

Then, the allowable riding rates of the users a to E to the car 11X are calculated based on the generated allowable riding rate maps of the users a to E and the calculated predicted waiting times of the users a to E. The calculated allowable riding rate for each of the users a to E to the car 11X is output to the riding rate calculating unit 311 (S18).

The riding-place permitted riding rate calculating unit 311 calculates the permitted riding rate for the riding place 20-1 based on the permitted riding rates of the users a to E calculated by the user permitted riding rate calculating unit 310A. The calculated allowable riding occupancy rate with respect to the riding place 20-1 is output to the control command output unit 312 (S19).

The control command output unit 312 determines whether or not the occupancy of the car 11X allocated by the allocated-car determining unit 308 exceeds the allowable riding rate at the riding place 20-1 calculated by the riding place allowable riding rate calculating unit 311, based on the information acquired by the elevator information managing unit 302A. When the determined result is that the occupancy of the car 11X exceeds the allowable riding rate of the car 20-1, an instruction to allow the car 11X to pass without stopping at the car 20-1 is output to the corresponding individual elevator control device 12X (S20).

Here, in the boarding area allowable riding rate calculating unit 311, it is considered to use the maximum value, the minimum value, or the median value of the allowable riding rates of the users a to E for the car 11X as the allowable riding rate of the boarding area 20-1.

If the maximum value of the allowable riding rates of the users a to E for the car 11X is used as the allowable riding rate at the elevator hall 20-1, there is a high possibility that all the passengers will not ride although there are people to ride. For example, as shown in fig. 7(a), the allowable occupancy rate of user a is 70%, the allowable occupancy rate of user B is 60%, the allowable occupancy rate of user C is 50%, the allowable occupancy rate of user D is 65%, and the allowable occupancy rate of user E is 63%. In this case, if the maximum value among the 5 persons, that is, the allowable riding rate of the user a of 70% is used as the allowable riding rate of the car hall 20-1, as shown in fig. 7(b), when the riding rate of the car 11X allocated first is 75%, the calculated allowable riding rate of the car hall 20-1 is higher than 70%, and therefore, a control instruction is output so that the car 11X is fully passed. When the newly assigned car 11Y is called to the car-entering location and the occupancy of the car 11Y is 68%, the calculated allowable car-entering occupancy of the car-entering location 20-1 is less than 70%, and therefore, a control instruction is output so that the car 11Y responds to the car-entering location 20-1. In this case, the possibility that the user a having the allowable riding rate of 70% rides in the car 11Y in response is high, and the possibility that the other users B to E (particularly, the users B and C) ride in the car 11Y is low.

In addition, if the minimum value of the allowable riding rates of the users a to E for the car 11X is used as the allowable riding rate of the elevator riding place 20-1, there is a high possibility that the users wait for a long time. For example, if the allowable riding rate 50% of the user C, which is the minimum value among the 5 users shown in fig. 7(a), is used as the allowable riding rate of the car floor 20-1, as shown in fig. 7(C), when the riding rate of the car 11X allocated first is 55%, the calculated allowable riding rate 50% of the car floor 20-1 is higher, and therefore, a control instruction is output so that the car 11X is fully passed. When the newly assigned car 11Y is called at the elevator hall and the occupancy of the car 11Y is 48%, the calculated allowable riding rate of the elevator hall 20-1 is less than 50%, and therefore, a control instruction is output so that the car 11Y responds to the elevator hall 20-1. In this case, even if the users A, B, D and E are highly likely to ride on the car 11X assigned first, there is a possibility that the users will pass through the car at all, and the operation efficiency will be low. Therefore, it is considered appropriate to use the maximum value of the allowable riding rates of the users a to E for the car 11X as the allowable riding rate of the corresponding car-riding place 20-1.

According to embodiment 1 described above, when the elevator answers the hall call, the riding rate of the car as the determination condition for whether or not the car is fully passed is determined according to the usage tendency of the user located at the hall, whereby the stop of the unnecessary car can be reduced, and the operation efficiency can be improved. The present embodiment is highly compatible with a system having a user authentication function, such as a DCS system, and can operate an elevator more efficiently and conveniently by using such a system.

EXAMPLE 2 EXAMPLE

In embodiment 2 of the present invention, a case where a plurality of elevator systems are installed in a large-scale building will be described. In such a case, there is a high possibility that users are shared among a plurality of buildings. Therefore, in embodiment 2 to be described below, the single occupancy determination database is shared by a plurality of elevators, thereby improving the learning efficiency of the usage tendency of the user.

< construction of Elevator System of embodiment 2 >

An elevator system according to embodiment 2 of the present invention is an in-building elevator system 2 installed in a large-scale building, and as shown in fig. 8, includes: the elevator system 1-1 of the 1 st elevator system 1-1 with elevator group management control device 30-1, the elevator system 1-2 of the 2 nd elevator system 1-2 with elevator group management control device 30-2, the elevator system 1-3 of the 3 rd elevator system 1-3 with elevator group management control device 30-3, and the riding judgment database storage device 40 connected with the elevator group management control devices 30-1 to 30-3 of the 1 st elevator system 1-1 to 3 rd elevator system 1-3.

As shown in fig. 9, the control devices of the 1 st elevator group management control device 30-1 to the 3 rd elevator group management control device 30-3 are the same as the configuration of the elevator system 1A described in embodiment 1 except that the occupancy determination database 305 is not provided, and therefore, detailed description thereof is omitted.

The occupancy determination database storage device 40 stores the occupancy determination information of each user transmitted from the 1 st elevator system 1-1, the 2 nd elevator system 1-2, and the 3 rd elevator system 1-3.

< operation of the elevator system according to embodiment 2 >

In the in-building elevator system 2 configured as described above, the occupancy determination information of each user output from the occupancy determination information output unit 304 of the elevator group management control device 30-1 of the 1 st elevator system 1-1, the occupancy determination information of each user output from the occupancy determination information output unit 304 of the elevator group management control device 30-2 of the 2 nd elevator system 1-2, and the occupancy determination information of each user output from the occupancy determination information output unit 304 of the elevator group management control device 30-3 of the 3 rd elevator system 1-3 are stored in the occupancy determination data base device 40.

When the 1 st elevator system 1-1, the 2 nd elevator system 1-2, and the 3 rd elevator system 1-3 perform the judgment processing of the full passenger passage, the taking judgment information acquisition unit 309 of each of the corresponding elevator group management control devices 30-1 to 30-3 acquires the taking judgment information of the corresponding user from the taking judgment database storage device 40.

According to embodiment 2 described above, when a plurality of elevator systems are present in the same building, the information of the usage history of the user is shared among the plurality of elevator systems, so that the learning efficiency of the usage history is improved, and the learning process of the usage history is performed on each of the same user in the plurality of elevator systems, whereby the sense of incongruity given to the user can be eliminated.

EXAMPLE 3

In embodiment 3 of the present invention, the learning efficiency of the usage tendency of the user and the management efficiency of the information are further improved by sharing one occupancy determination database among a plurality of elevator systems installed in a plurality of buildings.

< construction of Elevator System according to embodiment 3 >

An elevator system according to embodiment 3 of the present invention is an in-zone elevator system 3 in which a plurality of in-building elevators are connected between a plurality of buildings in a predetermined zone, and is configured such that a plurality of in-building elevator systems 2-1, 2-2, and 2-3 are connected to an occupancy determination database storage device 40, as shown in fig. 10. Each of the in-building elevator systems 2-1 to 2-3 has a plurality of elevator systems connected to the occupancy determination database storage device 40, similarly to the in-building elevator system 2 described in embodiment 2. For example, in-building elevator system 2-1 has 1 st elevator system 1-1, 2 nd elevator system 1-2, and 3 rd elevator system 1-3, in-building elevator system 2-2 has 4 th elevator system 1-4, 5 th elevator system 1-5, and 6 th elevator system 1-6, in-building elevator system 2-3 has 7 th elevator system 1-7, and 8 th elevator system 1-8. The configurations of the 1 st elevator system 1-1 to the 8 th elevator system 1-8 are the same as those of the elevator group management control devices 30-1 to 30-3 described in the embodiment 2, and therefore, detailed description thereof is omitted.

< operation of the elevator system according to embodiment 3 >

In the in-zone elevator system 3 configured as described above, the occupancy determination information of each user output from the occupancy determination information output unit 304 of the elevator group management control device 30 of each of the elevator systems 1-1 to 1-8 of the in-building elevator systems 2-1 to 2-3 is stored in the occupancy determination database storage device 40.

When the judgment processing for the passage of a full member is performed in the elevator systems 2-1 to 2-3 in the building, the occupancy judgment information of the corresponding user is acquired from the occupancy judgment database storage device 40 by the occupancy judgment information acquiring unit 309 of each corresponding elevator group management control device 30-1 to 30-8.

Since the history information is stored in the occupancy determination database storage device 40 of the elevator system 3 in this area for each user, a situation in which the same history information is accessed from a plurality of elevator systems at the same time does not occur in principle.

According to embodiment 3 described above, since information of the use history of the user is shared among a plurality of elevator systems installed in different buildings, it is possible to further improve the learning efficiency of the use history of the user, and to perform appropriate processing for determining the passage of a full person even in a building visited by the user for the first time in the area.

In the above-described embodiment 3, the occupancy determination information of each user stored in the occupancy determination database storage device 40 is stored in each category (for example, an office building, a shopping mall, or the like) based on the usage purpose of the corresponding building, and the occupancy determination information on the corresponding building is used in the determination process of the full occupancy, thereby enabling a more accurate process.

EXAMPLE 4 embodiment

< construction of Elevator System of embodiment 4 >

The elevator system 1B according to embodiment 4 of the present invention has the same configuration as the elevator system 1A described in embodiment 1, and therefore detailed description of portions having the same functions is omitted. The elevator information management unit 302B in the elevator group management control device 30B of the elevator system 1B acquires the operation mode information of the cars 11X and 11Y preset for each time slot from the individual elevator control device 12Y of elevator No. X12X, Y as the operation condition information of the elevator No. X10X and the elevator No. Y10Y. As the operation mode information, for example, there are a work-in mode for calling a waiting car to a floor having an entrance in the morning work time zone, a lunch mode for making 2 cars respond to the floor having a dining hall when a call is made at the elevator-taking place in the floor having the dining hall in the latter half of the lunch time zone, and the like.

In the present embodiment, the boarding determination information output unit 304B acquires, as boarding determination information, the waiting time, information indicating whether or not the opened car 11X or 11Y is parked, the minimum riding rate during the door opening period of the corresponding car 11X or 11Y, and the operation mode information for each user located at a certain car hall 20, based on the information acquired by the elevator information management unit 302B and the elevator waiting start time of each user acquired by the waiting start time acquisition unit 303, and outputs the information to the boarding determination database 305.

In the present embodiment, the user's allowable riding rate calculation unit 310B acquires the predicted arrival time and the operation mode information of the car 11, which responds to the new hall call received by the hall call receiving unit 306, from the elevator information management unit 302B. The predicted waiting time of each user at the corresponding elevator riding place is calculated based on the elevator waiting start time of each user at the corresponding elevator riding place acquired by the waiting start time acquisition unit 303 and the acquired predicted arrival time of the car 11. Further, based on the information acquired by the boarding determination information acquisition unit 309, an allowable boarding rate table is generated for each user located on the floor where the boarding determination call has occurred and for each operation mode information. Then, based on the generated permitted riding rate map and the calculated predicted waiting time of each user, the permitted riding rate of each user on the corresponding car 11 at the floor in the corresponding operation mode is calculated.

< operation of Elevator System of embodiment 4 >

Description will be given of (1) processing for learning the usage tendency of the user, (2) elevator boarding hall call assignment processing, and (3) processing for determining the passage of full passengers, which are executed when the elevator user a arrives at the elevator boarding hall 20-1 at floor 1 in the elevator system 1B according to the present embodiment.

(1) Processing for learning utilization tendency of user

The processing executed in the elevator system 1B to learn the usage tendency of each user will be described with reference to the time chart of fig. 11. In fig. 11, steps S1 to S3 are the same as those described in embodiment 1, and therefore, detailed description thereof is omitted. When the waiting time of the user a at the boarding location 20 is output in step S3, the boarding determination information output unit 304B acquires the minimum riding rate and the operation mode information during the door opening period of the corresponding car 11 from the elevator information management unit 302B. In addition, information indicating whether or not the user a has taken the car is acquired by whether or not the load applied to the car 11 increases during the door opening period or by analysis processing of the shot information by the camera device 22-1 (S7). The waiting time of the user a, the minimum occupancy rate during the door opening period of the car 11, information indicating whether or not the user a has engaged in the car 11 with the door opened, and the operation mode information are acquired as the entry determination information and output to the entry determination database (S5). The occupancy determination database 305 sequentially stores the occupancy determination information of each user outputted from the occupancy determination information output unit 304B (S6).

(2) Call assignment handling at elevator ride

The hall call allocation process executed when the user a of the elevator arrives at the hall 20-1 at floor 1 will be described with reference to the timing chart of fig. 12.

When the user a who has arrived at the boarding location 20-1 performs a call registration operation on the boarding location operation panel 21-1, the user a is received by the boarding location call receiving unit 306 of the elevator group management control device 30B. The information of the accepted elevator boarding completion call is output to the assignment evaluation value calculation unit 307 and the boarding determination information acquisition unit 309 (S11).

When the information of a new hall call is acquired from the hall call receiving unit 306, the assignment evaluation value calculation unit 307 calculates an evaluation value indicating the assigned priority of each of the cars 11X and 11Y for the hall call based on the operating condition information of the X-elevator 10X and the Y-elevator 10Y acquired by the elevator information management unit 302B. The evaluation value of each of the cars 11X and 11Y is calculated based on the operation content in the corresponding operation mode. The calculated evaluation value is output to the assigned car determination unit 308(S12, S13).

The assigned car determining unit 308 determines an assigned car to be called at the elevator boarding location based on the evaluation value calculated by the assigned evaluation value calculating unit 307, and outputs the determined assigned car to the control command output unit 312 and the user' S allowable occupancy rate calculating unit 310B (S14). The control command output unit 312 outputs a response command for the hall call to the individual elevator control device 12 corresponding to the car 11 determined as the assigned car (S15). This concludes the description of the call assignment process at the elevator boarding location.

(3) Judgment processing of full member passing

The following describes the processing for determining the full attendant trip executed when a new hall call is registered in the present embodiment with reference to the sequence chart of fig. 12.

When the information of the hall call is output from the hall call receiving unit 306, the riding determination information acquiring unit 309 identifies the user located at the hall 20-1 based on the imaging information of the camera device 22-1 of the floor 1 where the hall call has occurred. Then, the riding determination information of the specified user is acquired from the riding determination database 305, and is output to the user allowable riding rate calculation unit 310B (S16).

The user's allowable riding rate calculation unit 310B obtains the predicted arrival time of the car 11X responding to the new hall call and the current operation mode information from the elevator information management unit 302B. Then, the predicted waiting time of each user at the corresponding elevator hall 20-1 is calculated from the elevator waiting start time of the user at the corresponding elevator hall 20-1 acquired by the waiting start time acquisition unit 303 and the acquired predicted arrival time of the car 11X (S17). Further, based on the information acquired by the boarding determination information acquisition unit 309, a tolerable boarding rate table indicating the tolerable boarding rate at each waiting time is generated for each user located at the boarding location 20-1 where the boarding location call has occurred and for each operation mode information.

Then, the allowable riding rate of each user in the corresponding operation mode to the car 11X is calculated based on the generated allowable riding rate map and the calculated predicted waiting time of each user. The calculated allowable riding rate of each user for the car 11X is output to the riding-place allowable riding rate calculating unit 311 (S21). Thereafter, the processing of steps S19 and S20 executed by the boarding-location-allowable-occupancy-rate calculation unit 311 and the control-command output unit 312 is similar to that described in embodiment 1, and therefore, detailed description thereof is omitted.

According to the above embodiment 4, when the elevator answers the hall call, the riding rate of the car as the determination condition for whether or not to pass the full car is determined according to the usage tendency of each user in the corresponding operation mode, whereby the operation efficiency can be improved more accurately.

EXAMPLE 5 EXAMPLE

< construction of Elevator System of embodiment 5 >

The elevator system 1C according to embodiment 5 of the present invention has the same configuration as the elevator system 1A described in embodiment 1, and therefore detailed description of portions having the same functions is omitted. Fig. 13 shows a configuration of an elevator group management control device 30C of an elevator system 1C according to the present embodiment.

When a new elevator taking-in place call is received by the elevator taking-in place call receiving unit 306, the assignment evaluation value calculation unit 307C of the elevator group management control device 30C calculates an evaluation value indicating the assigned priority of each of the cars 11X and 11Y for the elevator taking-in place call based on the operating condition information of the X-elevator 10X and the Y-elevator 10Y to be group management controlled, which is acquired by the elevator information management unit 302. When the allowable riding rate at the boarding location is calculated in the boarding location allowable riding rate calculation unit 311 based on the calculated evaluation value, the evaluation value is updated based on the allowable riding rate at the boarding location.

The assigned car determining unit 308C determines an assigned car for the elevator riding place call based on the evaluation value first calculated by the assigned evaluation value calculating unit 307C, and outputs the determined assigned car to the user's allowable riding rate calculating unit 310. After that, when the evaluation value is updated in the assignment evaluation value calculation unit 307C, the information of the assigned car determined for the elevator hall call is updated based on the updated evaluation value, and is output to the control command output unit 312.

< operation of the Elevator System of embodiment 5 >

The processes (S1 to S6) of (1) learning the usage tendency of the user and (2) the hall call assignment processes (S11 to S14) executed in the elevator system 1C are the same as those described in embodiment 1, and therefore, detailed description thereof is omitted.

The following describes the processing for determining that (3) the elevator system 1C in the present embodiment has passed full, with reference to the time chart of fig. 14. In fig. 14, the processing performed in steps S16 to S18 is the same as that described in embodiment 1, and therefore, detailed description thereof is omitted.

In the present embodiment, the allowable riding rate for the riding place 20-1 calculated by the riding place allowable riding rate calculation unit 311 in step S22 is output to the assignment evaluation value calculation unit 307C. The assignment evaluation value calculation unit 307C updates the evaluation value calculated in step S13 based on the obtained allowable riding rate of the riding space 20-1. The updated evaluation value information is output to the assigned car determination unit 308 (S23).

The assigned car determination unit 308 updates the information of the assigned car determined in step S14 for the elevator hall call based on the evaluation value updated by the assigned evaluation value calculation unit 307. The updated information on the assigned car is output to the control command output unit 312 (S24). Then, a response command is output from the control command output unit 312 to the individual elevator control devices 12 corresponding to the assigned car 11 (S25).

According to the above embodiment 5, the operation efficiency can be further improved by not causing the car predicted not to be taken by the responding user to respond to the elevator riding place call.
