Abstract

The invention provides a group management control device and a group management elevator system. Conventionally, the moving time after the user gets off the elevator is not considered, and the moving time may be increased depending on the car on which the user gets. The hall call assigning unit assigns a hall call to one car selected from the plurality of cars so that the total travel time, which includes the time when a user moves from the terminal device to the elevator hall door corresponding to the car at the registration floor and the time when the user moves after getting off the elevator at the destination floor, is shortened, based on an assignment evaluation value calculated from the total travel time and the operation information of the plurality of cars that are group-managed by the elevator controller that controls the operation of the cars.

Description

Group management control device and group management elevator system

Technical Field

The present invention relates to a group management control device and a group management elevator system.

Background

As the scale of a building increases, the number of elevators arranged in the building, that is, the number of elevator cars that move up and down, increases. Therefore, the group management control device treats a plurality of cars as a group, and performs group management control on the plurality of cars appropriately, thereby achieving improvement in service such as reduction in waiting time for the users of the cars. In a group management control device of a destination floor reservation type, a user registers a destination floor using an information terminal device such as an entrance or exit of an elevator entrance or an elevator entrance provided in a registration floor, and can call an assigned car to the elevator entrance generated in the information terminal device.

The group management control device performs control to display the number of the car to which the hall call is assigned on a display unit provided in the information terminal device. The user confirms the car number displayed on the display unit and waits for the arrival of the car before the hall door specified by the car number. Thus, the user can get on the car arriving at the registration floor, move to the registered destination floor, and then get off the car.

As a conventional group management device for an elevator, for example, patent document 1 discloses a technique in which a group management control device selects a car in consideration of a walking time of a user and the number of floors of an elevator.

Prior art documents

Patent document

Patent document 1: international publication No. 2006/114877 single file

However, in the technique disclosed in patent document 1, only the moving time until the user gets on the car is considered, and the moving time after the user gets off the elevator is not considered. In general, a user gets on a car assigned to a hall call, moves to a destination floor, gets off the car, and then goes out of a predetermined exit to move to a destination. However, the moving time of the user after the user gets off the car varies depending on the position of the car on which the user gets. Therefore, according to the conventional technique, the car assigned to the hall call needs to spend a longer time in moving than the case where the user gets on another car.

Disclosure of Invention

The present invention has been made in view of such circumstances, and an object thereof is to shorten a travel time in a building in which an elevator is installed.

The group management control device according to the present invention includes: a hall call information collection unit for allowing a user to register a destination floor in a terminal device provided in a registration floor, thereby making a hall call at the terminal device, and collecting hall call information including the registration floor and the destination floor from the terminal device; and an elevator hall call assigning unit that assigns an elevator hall call to one car selected from the plurality of cars so that the total travel time is shortened, based on an assignment evaluation value calculated from the total travel time including the time when a user moves from the terminal device to elevator hall doors corresponding to the plurality of cars moving at a plurality of floors at a registration floor obtained from the elevator hall call information and the time when the user moves after getting off the elevator from the car at a destination floor, and the operation information of the plurality of cars group-managed by the car number control device that controls the operation of the cars.

In the present invention, the travel time in the building of the user can be shortened by using the car assigned to the hall call based on the assignment evaluation value including the travel time evaluation value calculated based on the total travel time including the time until the user gets on the car and the time after the user gets off the car.

The problems, configurations, and effects other than those described above will be apparent from the following description of the embodiments.

Detailed Description

Hereinafter, specific embodiments will be described with reference to the drawings. In the present specification and the drawings, the same reference numerals are given to components having substantially the same function or configuration, and redundant description is omitted.

[ embodiment 1 ]

Fig. 1 is an overall configuration diagram of a group management elevator system 3.

The group management elevator system 3 installed in a building includes, for example: the elevator control device 1 is provided in an elevator machine room not shown, and 6 cars 41 to 46 are provided in an elevator path not shown and managed by the elevator control device 1. The cars 41 to 46 are assigned elevator numbers in the order from the 1 st to the 6 th in turn. In the figure, for convenience, the cars 41 to 46 are shown in a row, but actually, as shown in fig. 3 described later, the cars are disposed in an elevator shaft 100 in which 3 cars are disposed with a passage therebetween.

Further, the group management elevator system 3 includes: information terminal devices 81 and 82, hall indication lamps (reservation lamps) 91 to 96, and hall doors 101 to 106 provided at the registration floors of the service floors of the cars 41 to 46. The information terminal devices 81 and 82 (an example of a terminal device) can communicate with the mobile terminal 10 carried by a user of the elevator. Then, the information terminal devices 81 and 82 generate hall calls by the user registering the destination floors. In the following description, the cars 41 to 46 and the hall doors 101 to 106 may be referred to as "cars" and "hall doors" without any reference signs. In fig. 1, a description will be given of a case where a user registers a destination floor in the information terminal device 81. In the present embodiment, the number of cars is set to 6, but the number of cars may be plural.

In the car 41 of the machine No. 1, an information terminal device 51 for registering a destination floor by a user and a car position display device 61 for displaying the current position of the car 41 are provided. A load sensor 71 for detecting the load of a user riding in the car 41 is provided at a lower portion of the floor of the car 41. In addition, in the car 42 of the machine 2, an information terminal device 52 for registering a destination floor by a user and a car position display device 62 for displaying the current position of the car 42 are provided. A load sensor 72 for detecting a load of a user riding in the car 42 is provided at a lower portion of a floor of the car 42. Similarly, in the car 46 of the 6 th elevator, the information terminal device 56 for registering a destination floor by a user and the car position display device 66 for displaying the current position of the car 46 are provided, and in the lower portion of the floor of the car 46, a load sensor 76 for detecting the load of the user riding in the car 46 is provided. The car of the 3 rd to 5 th machines, the information terminal device, the car position display device, and the load sensor are not described.

As the mobile terminal 10 carried by the user, for example, a mobile phone, a smart phone, an IC (integrated circuit) card, a magnetic card, or the like is used. The mobile terminal 10 can transmit and receive information to and from the information terminal device 81 by a contact method or a noncontact method. The user can register the destination floor with the information terminal device 81 by bringing the mobile terminal 10 close to the information terminal device 81. The mobile terminal 10 stores destination information in addition to the destination floor as an attribute. The destination information indicates from which of the a-side exit 85 or the B-side exit 86 (see the right side of fig. 3 described later) the user has exited to the destination 110 after the user has exited the car at the destination floor. In addition, the mobile terminal 10 can store special information such as a call from a wheelchair-dedicated boarding lobby.

The elevator control device 1 includes: the group management control device 2 and the number control devices 31-36 with the same number as the 6 cars 41-46. The group management control device 2 selects one car from the cars 41 to 46 to be assigned to the hall call generated from the information terminal device 81. The group management control device 2 controls the raising and lowering of the cars 41 to 46, the display of the car position display devices 61 to 66, the display of the elevator hall lanterns 91 to 96, and the like by the car control devices 31 to 36.

The car control devices 31-36 transmit car information to the car information collection unit 22. The car information includes destination floor information outputted from the information terminal devices 51 to 56 and load information indicating the load of the user outputted from the load sensors 71 to 76. In the following description, the car controllers 31 to 36 are referred to as "car controllers" without reference numerals when not distinguished from each other.

The group management control device 2 includes: an elevator hall call information collection unit 21, a car information collection unit 22, a travel time information storage unit 23, and an elevator hall call assignment unit 26.

When the user brings the mobile terminal 10 close to the information terminal device 81 to register a destination floor, the hall call information collection unit 21 collects hall call information from the information terminal device 81. The hall call information includes the registered floor information and the destination floor information read from the mobile terminal 10. The registration floor information is information indicating a registration floor where the information terminal device 81 is installed, and it is determined from the registration floor information that the registration floor is a lobby floor, for example. The destination floor information is information indicating a destination floor registered by the user via the information terminal device 81, and the destination floor is determined to be a workplace floor, for example, from the destination floor information. The hall call information collection unit 21 stores in advance identification information of the information terminal devices 81 provided on each floor. Therefore, the hall call information collection unit 21 can know which information terminal device 81 of the destination floor the user registered based on the identification information included in the collected hall call information. The hall call information collection unit 21 recognizes that a hall call has occurred and that the car has ascended or descended, based on the identification information of the information terminal device 81 included in the hall call information, the registration floor information read from the mobile terminal 10, and the destination floor information.

When the user moves from the work place floor to the lobby floor at the work place floor, the registration floor information indicates the work place floor, and the destination floor information indicates the lobby floor. The registered floor information and the destination floor information do not include floors other than the lobby floor and the workplace floor. Therefore, the user cannot go to floors other than the lobby floor and the workplace floor.

The car information collection unit 22 collects car information transmitted from the car control devices 31-36. The car information includes, for example: information on the operation status of the cars such as the positions, moving directions, and crowdedness in the cars 41 to 46 of the cars 41 to 46 transmitted from the car control devices 31 to 36.

As shown in fig. 4 to be described later, the travel time information storage unit 23 stores in advance a table indicating the total travel time including the time during which the user moves from the information terminal device 81 to the elevator hall door corresponding to the car at the registration floor and the time during which the user moves after getting off the elevator at the destination floor. The time when the user moves after getting off the elevator at the destination floor means, for example, the time when the user moves to the destination 110 through a predetermined exit after getting off the elevator. The total travel time is a value that is registered in advance in the travel time information storage unit 23 by performing predetermined simulation processing by an external device not shown, but may be calculated at any time by the hall call allocating unit 26.

When a new hall call is generated in the information terminal device 81 by the user registering the destination floor, the hall call allocating unit 26 performs a process of calculating the travel time evaluation value. In this process, the travel time evaluation value is calculated for each of the plurality of cars moving to the plurality of floors based on the total travel time including the time taken for the user to move from the information terminal device 81 to the elevator hall door corresponding to the car at the registration floor and the time taken for the user to move after the user has left the elevator at the destination floor, which is obtained from the hall call information. In the present embodiment, the time for a user to move after getting off the elevator at a destination floor is, as shown in fig. 4 to 6 described later, the time for the user to reach the destination after getting off the elevator through the a-side exit 85 or the B-side exit 86 (an example of a predetermined exit) provided at the destination floor. The total travel time is a value read by the hall call assignment unit 26 from the travel time information storage unit 23. In this way, the boarding lobby call allocation unit 26 calculates an allocation evaluation value based on the boarding lobby call information collected by the boarding lobby call information collection unit 21, the car information collected by the car information collection unit 22, and the travel time information registered in the travel time information storage unit 23.

The hall call assigning unit 26 assigns a hall call to one car selected from the cars so that the total travel time is shortened, based on an assignment evaluation value calculated from the total travel time and the travel information of the cars subjected to group management by the car number control device that controls the travel of the cars. Here, the hall call assigning unit 26 calculates an assignment evaluation value including moving time evaluation values calculated in order of shorter total moving time for a plurality of cars moving to a plurality of floors.

By assigning the hall call to one car in this manner, the car controller controls the operation of the car so that the car to which the hall call is assigned moves to the registration floor. In the present embodiment, the car assigned the car with the smallest evaluation value indicates that the travel time until the user reaches the destination 110 after using the information terminal device 81 is the smallest. The series of processing performed by the hall call assignment section 26 is performed according to a flow shown in fig. 7 described later.

Next, a hardware configuration of the computer C constituting each device of the elevator control device 1 will be described.

Fig. 2 is a block diagram showing an example of the hardware configuration of the computer C.

The computer C is hardware used as a so-called computer. The computer C includes: a CPU (central processing Unit) C1, a ROM (Read Only Memory) C2, and a RAM (random access Memory) C3, which are connected to a bus C4, respectively. Further, the computer C includes a nonvolatile storage device C5 and a network interface C6.

The CPU C1 reads and executes the program codes of the software that realizes the functions according to the present embodiment from the ROM C2. Variables, parameters, and the like generated during the arithmetic processing are temporarily written into the RAM C3. The operations of the group management control device 2 and the car control devices 31 to 36 are executed by, for example, the CPU C1.

As the nonvolatile storage device C5, for example, an HDD (Hard Disk Drive), an SSD (Solid State Drive), a flexible Disk, an optical magnetic Disk, a CD-ROM, a CD-R, a magnetic tape, a nonvolatile memory, or the like is used. The nonvolatile storage device C5 stores a program for causing the computer C to function, in addition to an OS (Operating System) and various parameters. The ROM C2 and the nonvolatile storage device C5 are used as an example of a computer-readable non-transitory recording medium that records programs, data, and the like necessary for the CPU C1 to operate and stores programs executed by the computer C. Therefore, the ROM C2 and the nonvolatile storage device C5 permanently store the program. The travel time information storage unit 23 is built in, for example, the nonvolatile storage device C5.

The Network Interface C6 can transmit and receive various data between devices via L AN (L annular Area Network), dedicated lines, and the like, for example, using AN NIC (Network Interface Card) or the like.

Next, the description will be given of the registration floor (floor 1) and the destination floor (floor 10) of the building.

Fig. 3 is an explanatory view showing the appearance of a destination 110 at floor 1 as a lobby floor and floor 10 as a destination floor. The left side of fig. 3 shows the appearance of 1 layer, and the right side of fig. 3 shows the appearance of 10 layers. In the figure, 1 layer is represented as "1F", and 10 layers are represented as "10F".

In each of floors 1 and 10, 3 cars, i.e., No. 1 to No. 3, are installed on the upper side of the figure, and 3 cars, i.e., No. 4 to No. 6, are installed on the lower side of the figure with a passage therebetween. The elevator shaft 100 of each car is assigned a car number to identify the car. The elevator shaft 100 into which each car enters is disposed near the center of each floor, and each floor is divided into a side a (e.g., the west side of the building) and B side (e.g., the east side of the building). In the following drawings, side a is denoted by "a" and side B is denoted by "B".

An information terminal device 81 is provided on the a side of layer 1, and an information terminal device 82 is provided on the B side. The current position of the user on level 1 is set to be in the vicinity of the information terminal device 81 on side a. In this case, the user brings the mobile terminal 10 close to the information terminal device 81 to register the destination floor. Then, the user moves to the elevator hall door having the elevator number corresponding to the car assigned by the hall call assigning unit 26.

Then, the user gets on the assigned car and gets off the elevator at 10 floors. In the 10 layers, the area surrounded by the chain line on the left side of the passage is the a-side outlet 85, and the area surrounded by the chain line on the right side of the passage is the B-side outlet 86. At floor 10, a user of the elevator from below the car of the No. 1 machine passes through the B-side exit 86 and moves to the destination 110. The destination 110 is, for example, a seat of the user, and is registered in advance as destination information in the mobile terminal 10.

The total travel time of the user to get on the car and arrive at the destination 110 is expressed by the following equation (1). In the present embodiment, the total movement time does not include the time when the user waits for the arrival of the car before the elevator hall door and the movement time when the car on which the user is riding is raised and lowered.

Total movement time (1) is the movement time of the user from the information terminal device to the assigned elevator + the movement time from the elevator car to the destination 110

In the conventional total travel time, the travel time from the time when the user gets off the car to the time when the user arrives at the destination 110 is not considered, and the total travel time may be increased depending on the car on which the user gets and the exit through which the user passes at the destination floor. On the other hand, in the present embodiment, a car whose travel time from when the user gets off the car to when the user arrives at the destination 110 is the shortest or can be shortened is assigned to the hall call.

Here, a specific example of the total travel time when the user moves to the destination 110 on the destination floor after registering the destination floor using any one of the information terminal devices 81 and 82 will be described with reference to fig. 4 to 6.

Fig. 4 shows an example of information stored in the travel time information storage unit 23. In the figure, the information terminal device 81 is described as an "a-side device", and the information terminal device 82 is described as a "B-side device". The a-side outlet 85 is referred to as "a-side" and the B-side outlet 86 is referred to as "B-side". The information stored for the machines No. 1 to No. 3 is the same as the information stored for the machines No. 4 to No. 6.

Fig. 5 is an explanatory diagram showing a movement trajectory and a movement time when a user of a destination floor is registered to a destination 110 by the information terminal device 81 on the a side. In fig. 5 and fig. 6 described later, the movement locus of the user who gets on the car of the machine No. 1 and gets off the elevator from the car of the machine No. 1 is shown by a solid line, and the movement locus of the user who gets on the car of the machine No. 3 and gets off the elevator from the car of the machine No. 3 is shown by a broken line. Hereinafter, the movement trajectory of the user will be described in terms of the movement time required for the user to move the movement trajectory by the distance.

As shown on the left side of fig. 5, when a user who has registered a destination floor with the information terminal device 81 on level 1 rides in the car of machine No. 1, the travel time of the user when the user goes from the information terminal device 81 to the hall door of machine No. 1 is t 1. When the user gets into the car of the 3 rd machine, the moving time of the user when the user goes from the information terminal device 81 to the hall door of the 3 rd machine is t 2.

As shown on the right side of fig. 5, the travel time when the user who gets off the car of the machine No. 1 goes out of the a-side exit 85 to the destination 110 is t11, and the travel time when the user goes out of the B-side exit 86 to the destination 110 is t 12. Further, the traveling time of the user who gets out of the car of the 3 rd machine and goes to the destination 110 through the a-side exit 85 is t21, and the traveling time of the user who gets out of the B-side exit 86 and goes to the destination 110 is t 22.

Therefore, the total travel time of the user who registered the destination floor with the information terminal device 81 and took the car of the machine No. 1 to go out from the a-side exit 85 to the destination 110 is represented by t1+ t11, and as is clear from the cell c1 of fig. 4, this time is 20 seconds. Further, the total moving time of the user when going out of the B-side exit 86 and going to the destination 110 is represented as t1+ t12, which is 25 seconds as seen from the unit c2 of fig. 4.

Further, the total travel time of the user who registered the destination floor with the information terminal device 81 and got on the car of the 3 rd machine from the a-side exit 85 to the destination 110 is represented as t2+ t21, which is 30 seconds as seen from the cell c3 in fig. 4. Further, the total moving time of the user when going out of the B-side exit 86 and going to the destination 110 is represented as t2+ t22, which is 25 seconds as seen from the unit c4 of fig. 4. In other words, when the user who registered the destination floor in the information terminal device 81 exits from the B-side exit 86, the total travel time is 25 seconds which is the same regardless of the car number of the car on which the user is riding.

In this way, when the user registers the destination floor in the information terminal device 81 and goes out from the a-side exit 85 which is far from the destination 110, the total travel time changes, whereas when going out from the B-side exit 86 which is near to the destination 110, the total travel time does not change. The hall call assignment unit 26 calculates the travel time evaluation value in the order of shorter total travel time, for example, "1" for 20 seconds, "2" for 25 seconds, and "3" for 30 seconds. Therefore, the hall call assigning unit 26 can calculate an assignment evaluation value from the travel time evaluation value calculated from the total travel time obtained from the table of fig. 4, and assign a hall call to the car based on the assignment evaluation value.

As shown in fig. 7, the hall call assigning unit 26 assigns hall calls in consideration of a waiting time evaluation value, an elevator state evaluation value, and the like, which will be described later, in addition to the travel time evaluation value, and therefore does not necessarily assign hall calls to cars having the smallest travel time evaluation value. Therefore, when a user who has registered a destination floor in the information terminal device 81 passes through the a-side exit 85 and goes to the destination 110, the machine No. 1 and the machine No. 4 become the most preferred allocation candidates in consideration of the travel time after the elevator is taken into account. The machine No. 2 and the machine No. 5 become next allocation candidates, and the machine No. 3 and the machine No. 6 become final allocation candidates. When the user passes through the B-side exit 86 and goes to the destination 110, the traveling time after the elevator is the same, and therefore, the machines 1 to 6 become allocation candidates. In this case, to which car the hall call is assigned varies depending on the running state of the car and the like.

Fig. 6 is an explanatory diagram showing a movement trajectory and a movement time when a user whose destination floor is registered by the information terminal device 82 on the B side goes to the destination 110.

As shown on the left side of fig. 6, when a user who has registered a destination floor with the information terminal device 82 on level 1 rides in the car of the 3 rd machine, the travel time when the user goes from the information terminal device 82 to the hall door of the 3 rd machine is t 3. When the user gets into the car of machine No. 1, the moving time of the user when the user goes from the information terminal device 82 to the hall door of machine No. 1 is t 4.

As shown on the right side of fig. 6, the travel time when the user who gets off the car of the 3 rd machine goes out of the a-side exit 85 to the destination 110 is t31, and the travel time when the user goes out of the B-side exit 86 to the destination 110 is t 32. The travel time when the user of the elevator getting out of the car of the No. 1 elevator goes out of the a-side exit 85 to the destination 110 is t41, and the travel time when the user goes out of the B-side exit 86 to the destination 110 is t 42.

Therefore, the total travel time of the user who registered the destination floor with the information terminal device 82 and took the car of the 3 rd machine to go out from the a-side exit 85 to the destination 110 is represented as t3+ t31, which is 25 seconds as seen from the cell c14 in fig. 4. Further, the total moving time of the user when going out from the B-side exit 86 and going to the destination 110 is represented as t3+ t32, which is 20 seconds as seen from the unit c13 of fig. 4.

Further, the total travel time of the user who registered the destination floor with the information terminal device 82 and got on the car of the machine number 1 when going out from the a-side exit 85 and going to the destination 110 is represented as t4+ t41, which is 25 seconds as seen from the cell c12 of fig. 4. Further, the total moving time of the user when going out from the B-side exit 86 and going to the destination 110 is represented as t4+ t42, which is 30 seconds as seen from the unit c11 of fig. 4. In other words, when the user who registered the destination floor in the information terminal device 82 goes out of the a-side exit 85, the total moving time is 25 seconds which is the same regardless of the car number of the car on which the user is riding.

In this way, when the user registers the destination floor in the information terminal device 82 and goes out from the B-side exit 86 closer to the destination 110, the total travel time changes, whereas when going out from the a-side exit 85 farther from the destination 110, the total travel time does not change. Therefore, the hall call allocating unit 26 can calculate the travel time evaluation value from the total travel time obtained from the table of fig. 4. The calculation method of the travel time evaluation value is the same as the method described in fig. 5.

When a user who has registered a destination floor in the information terminal device 82 goes to the destination 110 through the B-side exit 86, the 3 rd and 6 th elevators become the most preferred candidates for allocation in consideration of the travel time after the elevator is taken into account. The machine No. 2 and the machine No. 5 become next allocation candidates, and the machine No. 1 and the machine No. 4 become final allocation candidates. When the user goes to the destination 110 through the a-side exit 85, the traveling time after the elevator is dropped is the same, and therefore, the machines No. 1 to 6 are candidates for allocation. In this case, to which car the hall call is assigned varies depending on the running state of the car and the like.

The selection process of a plurality of cars by the hall call assigning unit 26 will be described below.

Fig. 7 is a flowchart showing an example of selection processing for assigning a new hall call to any of a plurality of cars. In the following processing, the user registers the destination floor using the information terminal device 81.

First, when a user brings the mobile terminal 10 close to the information terminal device 81 by a contact method or a non-contact method, the information terminal device 81 reads the registration floor information and the destination floor information from the mobile terminal 10. Then, the information terminal device 81 transmits the registration floor information and the destination floor information read from the mobile terminal 10 as hall call information. The hall call information collection unit 21 collects hall call information from the information terminal device 81 (S1).

Next, the hall call allocating unit 26 extracts the travel time of the user from the travel time information storage unit 23 based on the hall call information collected from the information terminal device 81 by the hall call information collecting unit 21 (S2). The travel time may be calculated every time the hall call distribution unit 26 takes the elevator.

Next, the hall call assigning unit 26 calculates an assignment evaluation value for each car based on the waiting time evaluation value, the elevator state evaluation value, the travel time evaluation value, and the like (S3). In the figure, the number n of elevators is generally described, but in the present embodiment, since there are 6 elevators identified as the number 1 to 6, n is 6, and 6 assignment evaluation values are calculated by the hall call assignment unit 26. The hall call assignment unit 26 calculates an assignment evaluation value by adding the evaluation values obtained for each car. The assigned evaluation value may be calculated by multiplying the evaluation values by the hall call assigning unit 26.

The waiting time evaluation value is a value for evaluating the waiting time from the floor where the current car is moving or stopping to the floor where the car reaches the registered floor where the user who registered the destination floor is located. The shorter the waiting time, the smaller the waiting time evaluation value, and the longer the waiting time, the larger the waiting time evaluation value.

The elevator state evaluation value is a value that evaluates important factors that affect the waiting time, such as deceleration of the car, the door opening state, and the like. When the car can be immediately started while moving or in a door closed state, the evaluation value of the elevator state becomes small. On the other hand, when the car is decelerated or stopped and the door is opened, the evaluation value of the elevator state becomes large.

The travel time evaluation value is a value that evaluates the total travel time when the user moves to the destination 110.

Next, the hall call assigning unit 26 compares the assignment evaluation values for each car, and assigns a hall call to the car with the smallest assignment evaluation value (S4). Then, the hall call assigning unit 26 transmits an assignment signal indicating that a hall call is assigned to the car corresponding to the car to which the hall call is assigned (S5). Thus, the car to which the hall call is assigned is driven by the car controller in a predetermined operation mode.

The hall call assigning unit 26 according to embodiment 1 described above calculates an assignment evaluation value of each car based on hall call information, operation information of a plurality of cars, and the like, and assigns a hall call to a car having the smallest assignment evaluation value. The assignment evaluation value includes a travel time evaluation value, which is a value considering the travel time when the user moves to the destination 110 after getting off the elevator. Therefore, the waiting time of the car on which the user rides can be shortened, and the moving time in the building can be shortened or minimized. Also, there is no unnecessary time caused by the movement of the user. In addition, the added value of the building provided with the group management elevator system 3 can be improved.

[ 2 nd embodiment ]

Next, a group management elevator system 3 according to embodiment 2 of the present invention will be described. The group management elevator system 3 can calculate an assignment evaluation value based on the travel time of the elevator to go to either the a-side exit 85 or the B-side exit 86 when the user is at the destination floor, and assign the hall call to the car. In the present embodiment, the time for the user to move after getting off the elevator at the destination floor is, as shown in fig. 8 to 10 described later, the time until the user arrives at the a-side exit 85 or the B-side exit 86 (an example of a predetermined exit) provided at the destination floor after getting off the elevator.

Fig. 8 shows an example of information stored in the travel time information storage unit 23. In this example, the floor of the registered floor and the destination floor, and the travel time based on any one of the information terminal devices 81 and 82 in which the user registered the destination floor are described. The information stored for the machines No. 1 to No. 3 is the same as the information stored for the machines No. 4 to No. 6.

Fig. 9 is an explanatory diagram showing a movement trajectory and a movement time when a user who has registered a destination floor by the information terminal device 81 on the a-side goes to the a-side exit 85. In fig. 9 and fig. 10 described later, the movement locus of the user riding in the car of the car 1 is shown by a solid line, and the movement locus of the user riding in the car of the car 3 is shown by a broken line. Hereinafter, the movement trajectory of the user will be described in terms of the movement time required for the user to move the movement trajectory by the distance. The hall call assigning unit 26 according to the present embodiment assigns a hall call to one car selected from a plurality of cars so that the time for a user to move after getting off the elevator at a destination floor is shortened.

As shown on the left side of fig. 9, when a user who has registered a destination floor with the information terminal device 81 on level 1 gets on the car of machine No. 1, the travel time when the user goes from the information terminal device 81 to the hall door of machine No. 1 is t 5. As seen in cell c21 of FIG. 8, t5 is 10 seconds. When the user gets on the car of machine No. 3, the moving time of the user when the user goes from the information terminal device 81 to the hall door of machine No. 3 is t 6. As seen in cell c22 of FIG. 8, t6 is 20 seconds.

As shown on the right side of fig. 9, the travel time from the user who gets off the car of the machine No. 1 to the exit 85 on the a side is t51, and as is clear from the cell c23 of fig. 8, t51 is 5 seconds. The travel time from the user of the elevator car of 3 rd machine to the a-side exit 85 is t61, and t61 is 15 seconds as seen from the cell c24 in fig. 8.

Therefore, the total travel time when the user of the car having registered the destination floor with the information terminal device 81 and riding the car of machine number 1 goes to the a-side exit 85 is represented by t5(10 seconds) + t51(5 seconds), and it is understood that this time is 15 seconds. The total travel time of the user who has the car of the 3 rd car to the a-side exit 85 is represented by t6(20 seconds) + t61(15 seconds), and this time is 35 seconds.

The hall call assigning unit 26 calculates an assignment evaluation value based on the travel time evaluation value calculated from the total travel time obtained from the table of fig. 8, and assigns a hall call to the car based on the assignment evaluation value. For example, the travel time evaluation value is calculated in the order of shorter total travel time, such as "1" for 15 seconds, "2" for 25 seconds, and "3" for 35 seconds. However, the hall call assigning unit 26 may calculate the travel time evaluation value in the order of the shorter travel time after the elevator is dropped.

Fig. 10 is an explanatory diagram showing a movement trajectory and a movement time when a user of a destination floor has arrived at the B-side exit 86, which is registered by the B-side information terminal device 82.

As shown on the left side of fig. 10, when a user who has registered a destination floor with the information terminal device 82 on level 1 rides in the car of machine No. 1, the travel time of the user when the user goes from the information terminal device 82 to the hall door of machine No. 1 is t 8. As seen in cell c32 of FIG. 8, t8 is 20 seconds. When the user gets into the car of the 3 rd machine, the moving time of the user when the user goes from the information terminal device 82 to the hall door of the 3 rd machine is t 7. As seen in cell c31 of FIG. 8, t7 is 10 seconds.

As shown on the right side of fig. 10, the travel time from the user who gets off the car of the machine No. 1 to the B-side exit 86 is t81, and as is clear from the cell c34 of fig. 8, t81 is 15 seconds. The travel time from the user of the elevator car of 3 rd machine to the B-side exit 86 is t71, and t71 is 5 seconds as seen from the cell c33 in fig. 8.

Therefore, the total travel time when the user of the car having registered the destination floor with the information terminal device 82 and riding the machine No. 1 goes to the B-side exit 86 is represented by t8(20 seconds) + t81(15 seconds), and it is understood that this time is 35 seconds. The total travel time of the user of the car riding the 3 rd car to the B-side exit 86 is represented by t7(10 seconds) + t71(5 seconds), and this time is 15 seconds.

The hall call assigning unit 26 calculates an assignment evaluation value from the travel time evaluation value calculated from the total travel time obtained from the table of fig. 8, and assigns a hall call to the car based on the assignment evaluation value. The calculation method of the travel time evaluation value is the same as the method described in fig. 9.

In the group management elevator system 3 according to embodiment 2 described above, the movement time to the hall doors after the user registers the destination floor in the information terminal devices 81 and 82 is separated from the movement time to the a-side exit 85 or the B-side exit 86 after the user gets off the elevator. Therefore, the hall call assigning unit 26 can calculate the moving time evaluation value based on the moving time of the user to the hall door of each elevator and the moving time after the user gets off the elevator. The hall call assigning unit 26 may calculate the following travel time evaluation value: even when a user takes a car, the car has a longer moving time than the waiting time of the car, and the car having a shorter moving time after the user takes the car is preferentially assigned with a hall call. For example, if the time taken to reach the B-side exit 86 on the 10 th floor is 5 seconds, the boarding hall call assigning unit 26 can calculate the moving time evaluation value for preferentially assigning the boarding hall call to the car of the 3 rd car or the 6 th car.

In addition, after the user registers the destination floor in any one of the information terminal devices 81 and 82, if the hall door of the car that has reached the registration floor is to be closed until the user goes to the hall door of each elevator, the car can be removed from the assignment target of the hall call. In other words, the hall call assigning unit 26 may calculate the moving time evaluation value for assigning the hall call to a car whose waiting time is longer than the moving time with priority. The hall call assignment unit 26 can calculate an assignment evaluation value based on the travel time evaluation value and the operation information of the car, and assign a hall call to the car having the smallest assignment evaluation value.

In addition, the travel time from each of the 10 th floors in fig. 8 to the a-side outlet 85 may be set as the travel time from the a-side outlet 85 to the destination 110. Similarly, the travel time from each of 10 floors to the B-side outlet 86 may be set as the travel time from the B-side outlet 86 to the destination 110.

[ modified examples ]

The hall call assigning unit 26 may define a plurality of assignment evaluation values within a certain range, and assign the hall call to the car with priority, if the assignment evaluation value is within the range and is not the smallest.

In addition, each evaluation value may be set to a larger value in the order of higher evaluation. For example, "3" in the case of 20 seconds, "2" in the case of 25 seconds, and "1" in the case of 30 seconds, the larger moving time evaluation value is calculated in the order of shorter total moving time. The hall call assigning unit 26 may assign the car with the largest evaluation value by priority, and assign the hall call. The hall call assigning unit 26 may define a plurality of assignment evaluation values within a certain range, and assign the hall call to the car with priority, if the assignment evaluation value is not the maximum within the range.

Instead of the travel time, the travel distance of the user may be calculated as a travel distance evaluation value, and the hall call may be assigned to the car selected based on the assignment evaluation value including the travel distance evaluation value.

The total travel time may include a time when the user waits for the arrival of the car before the elevator hall door and a travel time when the car on which the user rides is raised and lowered.
