Elevator group management system

Abstract

The elevator group management system estimates that the arrival prediction time from the time when the registration of the landing call is accepted to the time when the user takes the elevator at the landing floor of the landing call and arrives at the landing floor of the landing destination call is relatively long for the elevator car responding to the landing destination call. When a large number of users take the elevator at the landing floor of the landing call before the elevator arrives at the landing floor of the landing destination call, the elevator car responding to the landing destination call can be prevented from being distributed to the landing call. The elevator group management system is provided with a determination unit that, when the registration of the landing call is newly accepted, determines that the arrival predicted time from the time when the registration of the landing call is accepted until the user rides at the landing floor of the landing call and arrives at the landing floor of the landing destination call is equal to or greater than a preset threshold value, and if the arrival predicted time is equal to or greater than the preset threshold value, determines that the user arrives at the landing floor of the landing destination call. An exclusion control is implemented that does not determine a car that is being responsive to a landing destination call as a car that is responsive to a landing call.

Description

TECHNICAL FIELD

[0001] The present application relates to an elevator group management system. BACKGROUND

[0002] In an elevator, as a method of calling a car to a landing, there are a landing call that specifies an up-down floor direction from a landing to a destination floor to call a car to a landing of a boarding floor and a landing destination call that specifies a destination floor to call a car to a landing of a boarding floor.

[0003] For example, in Patent Literature 1, an elevator group management control device that uses both a landing call and a landing destination call is disclosed. Further, in the invention described in Patent Literature 1, when a landing call or a landing destination call is registered, a predicted arrival time from the registration of the landing call or the landing destination call to the arrival at a boarding floor of the landing call or the landing destination call is calculated, and an evaluation of a car in which the predicted arrival time is shorter among candidates of a car that can respond to the landing call or the landing destination call, that is, assignment candidates, is preferably performed in a manner in which an evaluation value is calculated for each of the candidates. Moreover, the invention described in Patent Literature 1 determines a car that becomes the best evaluation value among the candidates as an assignment machine of the landing call or the landing destination call.

[0004] Here, in a case where a car that responds to a landing destination call arrives at a boarding floor of a landing call before arriving at a boarding floor of the landing destination call, a user who registered the landing call rides in the car, and the car can become a full load state before arriving at the boarding floor of the landing destination call. In this case, a user who registered the landing destination call and waits at the boarding floor of the landing destination call cannot board the car. Further, even if a user who waits at the boarding floor of the landing destination call boards the car, since the user who registered the landing call rides in the car, it is possible to arrive at a destination floor of the landing call before arriving at the destination floor of the landing destination call, and so on, and thus the convenience of the user who registered the landing destination call is reduced.

[0005] Therefore, in the invention described in Patent Document 1, when a new landing destination call is newly registered for a car that has already registered a landing call, and the car that responds to the landing call reaches the boarding floor of the new landing destination call before reaching the boarding floor of the new landing destination call, the evaluation value of the car that responds to the landing call is lowered. Furthermore, in the invention described in Patent Document 1, when a new landing call is newly registered for a car that has already registered a landing destination call, and the car that responds to the landing destination call reaches the boarding floor of the new landing destination call before reaching the boarding floor of the new landing destination call, the evaluation value of the car that responds to the landing destination call is lowered. Thus, in the invention described in Patent Document 1, it is possible to prevent users who have registered a landing call from riding in the car that has already responded to the landing destination call, thereby preventing a reduction in convenience for users who have registered the landing destination call.

[0006] Patent Document 1: Japanese Patent Application Publication No. 2019-55836

[0007] However, in the invention described in Patent Document 1, even if the evaluation value of a car is lowered, that car is not excluded from being assigned to a new landing destination call or a new landing call. Therefore, for example, even if the evaluation value of a car responding to an already registered landing destination call is lowered, if that car's evaluation value is better than that of other cars, that car will be assigned to the new landing call. In this case, even if the predicted arrival time for a car responding to a landing destination call is longer from the time the landing call is registered until a user boards the landing call's boarding floor and arrives at the landing call's boarding floor, that car will still be assigned to that landing call. Since it is estimated that a longer predicted arrival time means a greater number of users board the landing call's boarding floor, there is a possibility that convenience for users who registered that landing destination call will be reduced. Summary of the Invention

[0008] The present invention is completed to solve the above-mentioned problems, and its purpose is to provide an elevator group management system, in which, for a car responding to a floor destination call, the arrival predicted time from the time when the registration of the floor call is accepted to the time when the user gets on the elevator at the floor call floor and arrives at the floor call floor of the floor destination call can be longer, and in the case where a large number of users get on the elevator at the floor call floor before arriving at the floor call floor of the floor destination call, the car responding to the floor destination call can be suppressed from being allocated to the floor call.

[0009] The elevator group management system of the present application manages a plurality of cars, characterized in that the elevator group management system has: a reception unit that receives registration of a landing destination call and a landing call from a user, the landing destination call designating a destination floor to call a car, the landing call designating a direction of up or down floor to call a car; a predicted arrival time calculation unit that calculates a predicted arrival time from when the reception unit receives registration until a car arrives at a boarding floor where the user boards; a decision unit that decides a car that responds to at least one of the landing destination call and the landing call based on the predicted arrival time, the decision unit implementing exclusion control that does not decide the car that is responding to the landing destination call as the car that responds to the landing call in a case where registration of the landing call is newly received while the car that responds to the landing call is decided to move to the boarding floor of the landing call, in a case where the predicted arrival time from when the registration of the landing call is received until the user boards at the boarding floor of the landing call and arrives at the boarding floor of the landing destination call is equal to or more than a threshold value that is set in advance.

[0010] Further, the elevator group management system of the present application manages a plurality of cars, characterized in that the elevator group management system has: a reception unit that receives registration of a landing destination call and a landing call from a user, the landing destination call designating a destination floor to call a car, the landing call designating a direction of up or down floor to call a car; a predicted arrival time calculation unit that calculates a predicted arrival time from when the reception unit receives registration until a car arrives at a boarding floor where the user boards; and a decision unit that decides a car that responds to at least one of the landing destination call and the landing call based on the predicted arrival time, the decision unit implementing exclusion control that does not decide the car that is responding to the landing call as the car that responds to the landing destination call in a case where registration of the landing destination call is newly received while the car that responds to the landing call is decided to move to the boarding floor of the landing call, in a case where the predicted arrival time from when the registration of the landing call is received until the user boards at the boarding floor of the landing call and arrives at the boarding floor of the landing destination call is equal to or more than a threshold value that is set in advance.

[0011] According to the present application, an elevator group management system has a decision section that, in a case where a predicted arrival time from when registration of a hall call is accepted until a user boards the hall call at a boarding floor and arrives at a boarding floor of a hall destination call is equal to or more than a threshold value set in advance, causes the car responding to the hall destination call not to be assigned to the hall call. Thus, it is possible to provide an elevator group management system in which, for a car responding to a hall destination call, in a case where it is estimated that a predicted arrival time from when registration of a hall call is accepted until a user boards the hall call at a boarding floor and arrives at a boarding floor of a hall destination call is long, and a large number of users board the hall call at the boarding floor before arriving at the boarding floor of the hall destination call, the car responding to the hall destination call is inhibited from being assigned to the hall call.

DETAILED DESCRIPTION

[0027] Hereinafter, the elevator group management system of the embodiments will be described with reference to the drawings. The following embodiments are nothing more than examples, and the embodiments can be appropriately combined and each of the embodiments can be appropriately changed. In the drawings, the same reference signs are attached to the same structures.

[0028] Embodiment 1.

[0029] Use Figure 1 , the elevator group management system 100 in Embodiment 1 will be described. Figure 1 is a structural diagram of the elevator group management systems 100, 101, 102 of Embodiment 1, Embodiment 2, and Embodiment 3. Hereinafter, each structure of the elevator group management system 100 will be described, but the same applies to the elevator group management system 101, the elevator group management system 102. The elevator group management system 100 is a management system of an elevator group that uses both landing calls and landing destination calls. The elevator group has a plurality of cars. The elevator group is provided in a building or the like having a plurality of floors, for example.

[0030] As Figure 1As shown, the elevator group management system 100 has a reception unit 11, a predicted arrival time calculation unit 12, a decision unit 13, a notification unit 14, and a storage unit 15. In a case where a hall call or a hall destination call is registered, the elevator group management system 100 decides a car that responds to the hall call or the hall destination call, thereby managing an elevator group having a plurality of cars. A user calls a car to a boarding floor and boards the car, and gets off the car at a destination floor, thereby being able to move to a different floor by an elevator. Here, the car responding to the hall call or the hall destination call means that the car moves to a boarding floor of the hall call or the hall destination call, a user gets on the car at the boarding floor, and the car arrives at a destination floor of the hall call or the hall destination call.

[0031] The reception unit 11 receives registration of a hall call from a user. The hall call designates an up-down floor direction and calls a car to a boarding floor. That is, in a case where the user moves to a floor higher than the boarding floor, the up direction is designated. In addition, in a case where the user moves to a floor lower than the boarding floor, the down direction is designated. The user registers the hall call, for example, by a button or the like provided at a hall at the boarding floor where the user gets on the car. In addition, the reception unit 11 measures an elapsed time from registration of the hall call.

[0032] In addition, the reception unit 11 receives registration of a hall destination call from a user. The user designates a destination floor and calls a car to a boarding floor. The user designates the boarding floor and the destination floor, for example, by an application of a smartphone or the like, and registers the hall destination call. The reception unit 11 can perform wireless communication with the smartphone of the user. The reception unit 11 judges that the user waits at a hall at the boarding floor when detecting that the smartphone of the user approaches the hall at the boarding floor, and causes the car to go to the boarding floor. In addition, the reception unit 11 measures an elapsed time from registration of the hall destination call.

[0033] The reception unit 11, when receiving registration of a hall call from a user, acquires information of a boarding floor at which the user gets on a car, an up-down floor direction from the boarding floor to a destination floor, and an elapsed time from registration of the hall call, and transmits the acquired information to the predicted arrival time calculation unit 12, the decision unit 13, and the storage unit 15 as hall call information.

[0034] In addition, the reception unit 11, when receiving registration of a hall destination call from a user, acquires information of a boarding floor at which the user gets on a car, a destination floor at which the user gets off the car, an up-down floor direction from the boarding floor to the destination floor, and an elapsed time from registration of the hall destination call, and transmits the acquired information to the predicted arrival time calculation unit 12, the decision unit 13, and the storage unit 15 as hall destination call information.

[0035] The arrival prediction time calculating section 12 calculates an arrival prediction time from the time when the registration of the hall call or the hall destination call is accepted by the accepting section 11 to the time when the car arrives at the floor where the user gets on the car. The arrival prediction time calculating section 12 receives the hall call information and the hall destination call information from the accepting section 11. Further, the arrival prediction time calculating section 12 receives the past arrival prediction times from the storage section 15. The arrival prediction time calculating section 12 calculates the arrival prediction time, for example, based on the number of floors between the floor where the car is located and the floor where the user gets on the car or the destination floor, the time period during which the car runs, and the elapsed time that is measured in the past in the same section as the section in which the arrival prediction time is calculated. The arrival prediction time calculating section 12 is not limited to the above, and any method can be used for the calculation of the arrival prediction time. Further, the arrival prediction time calculating section 12 transmits the calculated arrival prediction time to the decision section 13 and the storage section 15.

[0036] The decision section 13 decides the car that responds to the registered hall call or hall destination call. That is, the decision section 13 receives the information related to the section in which each car can run from the storage section 15, and based on the information, extracts the allocation candidates of the car that can respond to the hall call and the hall destination call. Then, the decision section 13 receives the arrival prediction time from the arrival prediction time calculating section 12, and based on the arrival prediction time, decides the car that responds to at least one of the hall destination call and the hall call from the allocation candidates. Further, the decision section 13 transmits the information that identifies the car decided to respond to the hall call to the storage section 15. Further, the decision section 13 transmits the information that identifies the car decided to respond to the hall destination call to the storage section 15.

[0037] The notification section 14 notifies at least one of the user who registered the hall call or the hall destination call and is waiting at the floor where the user gets on the car and the user who has boarded the car of the stop factor. The stop factor includes at least one of the information that the floor where the car stops is the floor where the user gets on the car for the hall call, the information that the floor where the car stops is the floor where the user gets off the car for the hall call, the information that the floor where the car stops is the floor where the user gets on the car for the hall destination call, and the information that the floor where the car stops is the floor where the user gets off the car for the hall destination call. That is, the notification section 14 receives the registered hall call information and the hall destination call information from the storage section 15, and notifies the user who is waiting at the floor where the user gets on the car and the user who has boarded the car of the stop factor of the car that stops, whereby the user's misgetting on the car and misgetting off the car can be suppressed.

[0038] The notification section 14 can perform the notification by any method. The notification section 14 can perform the notification, for example, by the sound of a speaker, the display of a monitor, and the flickering of a prediction light, and the like. Further, the notification section 14 can switch the lighting and the extinguishing of the prediction light, whereby the notification can be performed, or can switch the flickering interval of the prediction light, whereby the notification can be performed, for example, in the case where the notification is performed by the flickering of the prediction light.

[0039] The storage section 15 stores information related to the number of cars set and the sections in which each car can run among a plurality of floors. Further, the storage section 15 receives and stores the arrival prediction time calculated by the arrival prediction time calculation section 12 from the arrival prediction time calculation section 12. Further, the storage section 15 receives and stores the hall call information and the hall destination call information from the reception section 11. Further, the storage section 15 receives the information identifying the car decided to respond to the hall call and the information identifying the car decided to respond to the hall destination call from the decision section 13. Further, the information stored in the storage section 15 is transmitted to the arrival prediction time calculation section 12, the decision section 13, and the notification section 14.

[0040] Next, the hardware configuration example of each structure in Embodiment 1, that is, the reception section 11, the arrival prediction time calculation section 12, the decision section 13, and the storage section 15 will be described. Figure 2 is a block diagram showing a hardware configuration example of each structure of Embodiment 1. In addition, the following description is also the same in the hall destination call occupancy rate calculation section 19 described later. Each structure of the elevator group management system 100 can be as shown in Figure 2 (A) of Figure 2 (B) of

[0041] As shown in (A) of Figure 2 In the case where each structure of the elevator group management system 100 is a dedicated hardware, the processing circuit 16 is, for example, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC (Application Specific Integrated Circuit), an FPGA (Field-Programmable Gate Array), or a component combining them. The functions of each structure of the elevator group management system 100 can be realized by the processing circuit 16 respectively, or the functions of each section can be realized by one processing circuit 16 collectively.

[0042] As shown in (B) of Figure 2 In the case where each structure of the elevator group management system 100 is the processor 17, the functions of each section are realized by software, firmware, or a combination of software and firmware. The software or firmware is described as a program and stored in the storage 18. The processor 17 realizes each function of each structure of the elevator group management system 100 by reading out and executing the program stored in the storage 18. That is, each structure of the elevator group management system 100 has a function for storing the results of executing the program described later when executed by the processor 17. Figure 3 Figure 5 Figure 7 and​​Figure 12 The memory 18 stores programs of procedures of each step shown. In addition, these programs can also be said to be programs that cause a computer to execute steps or methods of each configuration of the elevator group management system 100.

[0043] Here, the processor 17 is, for example, a CPU (Central Processing Unit), a processing device, an arithmetic device, a processor, a microprocessor, a microcomputer, a DSP (Digital Signal Processor), or the like. The memory 18 can be, for example, a RAM (Random Access Memory), a ROM (ReadOnly Memory), a flash memory, an EPROM (Erasable Programmable ROM), an EEPROM (Electrically EPROM), or the like, a nonvolatile or volatile semiconductor memory, a hard disk, a flexible disk, or the like, or a mini disk, a CD (Compact Disc), a DVD (Digital Versatile Disc), or the like.

[0044] In addition, each function of each configuration of the elevator group management system 100 can be implemented by a part of a dedicated hardware and a part of software or firmware. In this way, the processing circuit 16 in the elevator group management system 100 can implement each function described above by hardware, software, firmware, or a combination thereof.

[0045] Next, the processing flow of the elevator group management system 100 in the embodiment 1 will be described. Figure 3 is a flowchart showing the processing flow of the elevator group management system 100 in the embodiment 1. In addition, Figure 3 shows the processing flow of the elevator group management system 100 in a case where registration of a hall call is newly accepted when it is decided that the car that responds to the landing destination call moves to the landing destination call floor. In addition, Figure 4 is a specific example of the processing of the elevator group management system 100 in the embodiment 1. In Figure 4 , the elevator group has a car A, a car B, and a car C, and the car A and the car B can operate on the 1st floor to the 10th floor. In addition, the car C can operate on the 1st floor, the 8th floor to the 10th floor, and cannot operate on the 2nd floor to the 7th floor. In addition, in Figure 4 , the car A is located on the 8th floor, and moves to the registered landing destination call floor, that is, the 4th floor. In addition, in Figure 4 , the car B is located on the 9th floor, and the car C is located on the 10th floor. In addition, in Figure 4In the 6th floor, a new landing call in the down direction is registered.

[0046] In step S101, the reception part 11 receives registration of a new landing call from a user. At this time, the reception part 11 acquires information of a boarding floor at which the user boards a car and a direction of up and down floors from the boarding floor to a destination floor, and transmits the acquired information to the decision part 13. For example, in the case where the user boards the car at the 6th floor and the direction of up and down floors from the boarding floor to the destination floor is the down direction, the reception part 11 acquires such information. Figure 4 In the 6th floor, a new landing call in the down direction is registered.

[0047] In step S102, the decision part 13 receives information on intervals in which each car can run from the storage part 15, and extracts assignment candidates of cars that can respond to the new landing call. For example, in the case where the car A and the car B can run in the 1st to 10th floors and the car C cannot run in the 2nd to 7th floors, the decision part 13 extracts the car A and the car B as assignment candidates of cars that can respond to the new landing call. Figure 4 In the 6th floor, a new landing call in the down direction is registered.

[0048] In step S103, the decision part 13 acquires landing destination call information of a landing destination call that has been registered from the storage part 15, and extracts a car that has been decided to respond to a landing destination call and move to a boarding floor of the landing destination call, among assignment candidates of cars that can respond to the new landing call. For example, in the case where the car A moves to the 4th floor that is a boarding floor of a registered landing destination call, the decision part 13 extracts the car A. Figure 4 In the 6th floor, a new landing call in the down direction is registered.

[0049] In step S104, the decision part 13 determines, with respect to a car that moves to a boarding floor of an extracted landing destination call, whether there is a car that moves in the same direction as a direction in which the car that moves to the boarding floor of the landing destination call moves, among directions of up and down floors specified in the new landing call. For example, in the case where the car A moves in the down direction and a direction of up and down floors specified in the new landing call is the down direction, the decision part 13 determines that the directions are the same. Figure 4 In the 6th floor, a new landing call in the down direction is registered.

[0050] In the case where there is a car that satisfies the condition of step S104 (step S104: Yes), in step S105, the arrival prediction time calculation part 12 calculates, with respect to the car, an arrival prediction time from when registration of the landing call is received to when the user boards at a boarding floor of the landing call and arrives at a boarding floor of a landing destination call. For example, in the case where the car A moves in the down direction and a direction of up and down floors specified in the new landing call is the down direction, the arrival prediction time calculation part 12 calculates an arrival prediction time from when registration of the landing call is received to when the user boards at the 6th floor and arrives at the 4th floor. Figure 4In this case, the arrival prediction time calculation section 12 calculates, for the car A, the arrival prediction time from when the new hall call for the 6th floor is accepted until the user gets on the car A at the 6th floor and arrives at the 4th floor. Further, in a case where there is no car that satisfies the condition of step S104 (step S104: No), the process proceeds to step S108.

[0051] In step S106, the decision section 13 determines, for the car that satisfies the condition of step S104, whether there is a car for which the arrival prediction time calculated in step S105 by the arrival prediction time calculation section 12 is equal to or more than a threshold value set in advance. For example, in a case where the number of cars is three, the decision section 13 determines whether the arrival prediction time of the car A is equal to or more than the threshold value set in advance. Figure 4 In this case, the decision section 13 determines whether the arrival prediction time of the car A from when the new hall call for the 6th floor is accepted until the user gets on the car A at the 6th floor and arrives at the 4th floor is equal to or more than the threshold value set in advance.

[0052] The threshold value set in advance with which the arrival prediction time is compared in step S106 is appropriately set to an arbitrary value. For example, the decision section 13 can set the threshold value in accordance with the layout of the hall, the number of cars, the current location of the user who registered the hall destination call, the characteristics of the user who registered the hall destination call, and the like. The characteristics of the user indicate the nature of the user, such as whether or not the user uses a wheelchair, whether or not the user uses a baby carriage, whether or not the user has a cargo, age, and the like. At this time, the user can register his or her characteristics when specifying the boarding floor and the destination floor from the application of the smartphone.

[0053] For example, the more the number of cars, the more the number of remaining cars that can be coped with even if the exclusion control is implemented, and therefore the decision section 13 can set the threshold value to be small. Further, for example, the farther the current location of the user who registered the hall destination call is from the hall of the boarding floor, the longer the time until the user arrives at the hall of the boarding floor, and therefore the decision section 13 can set the threshold value to be large.

[0054] In a case where there is a car for which the arrival prediction time is equal to or more than the threshold value set in advance (step S106: Yes), in step S107, the decision section 13 determines to implement the exclusion control that does not decide the car that is responding to the hall destination call as the car that responds to the new hall call. For example, in a case where the arrival prediction time of the car A calculated in step S106 is equal to or more than the threshold value set in advance, the decision section 13 determines to implement the exclusion control that does not decide the car A as the car that responds to the new hall call registered at the 6th floor. Further, in a case where there is no car for which the arrival prediction time is equal to or more than the threshold value set in advance (step S106: No), the process proceeds to step S108. Figure 4 In this case, the decision section 13 determines whether the arrival prediction time of the car A from when the new hall call for the 6th floor is accepted until the user gets on the car A at the 6th floor and arrives at the 4th floor is equal to or more than the threshold value set in advance.

[0055] In step S108, the decision section 13 decides, on the basis of excluding the car judged in step S107 to implement the exclusion control of not deciding the car responding to the new landing call as the car responding to the new landing call, the car with the arrival prediction time calculated by the arrival prediction time calculation section 12 being the shortest as the assignor responding to the new landing call. For example, in the case shown in Fig. 6, the decision section 13 excludes the car A judged in step S107 to implement the exclusion control of not deciding the car responding to the new landing call registered at the 6th floor as the car responding to the new landing call, and decides the car B as the car responding to the new landing call. Further, in the case where there is no more assignment candidate by excluding the car judged in step S107 to implement the exclusion control of not deciding the car responding to the new landing call, the decision section 13 decides, as the assignor responding to the new landing call, the car with the arrival prediction time from the time when the registration of the landing call is accepted to the boarding floor of the landing destination call being the shortest among the assignment candidates extracted in step S102. Figure 5 In the case shown in Fig. 6, the decision section 13 excludes the car A judged in step S107 to implement the exclusion control of not deciding the car responding to the new landing call registered at the 6th floor as the car responding to the new landing call, and decides the car B as the car responding to the new landing call. Further, in the case where there is no more assignment candidate by excluding the car judged in step S107 to implement the exclusion control of not deciding the car responding to the new landing call, the decision section 13 decides, as the assignor responding to the new landing call, the car with the arrival prediction time from the time when the registration of the landing call is accepted to the boarding floor of the landing destination call being the shortest among the assignment candidates extracted in step S102.

[0056] The above completes the explanation of the processing flow of the elevator group management system 100 in Embodiment 1.

[0057] Thus, the elevator group management system 100 in Embodiment 1 has the decision section 13 which, in the case where the registration of the landing call is newly accepted while the car decided to respond to the landing destination call moves to the boarding floor of the landing destination call, judges to implement the exclusion control of not deciding the car responding to the landing destination call as the car responding to the landing call in the case where the arrival prediction time from the time when the registration of the landing call is accepted to the boarding floor of the landing destination call is equal to or more than the threshold value set in advance, and decides the car responding to the new landing call from among the assignment candidates on the basis of excluding the car. By being configured as described above, although it can be estimated that the arrival prediction time from the time when the registration of the landing call is accepted to the boarding floor of the landing destination call is long for the car responding to the landing destination call, and a large number of users board at the boarding floor of the landing call before arriving at the boarding floor of the landing destination call, the elevator group management system 100 can also suppress the car responding to the landing destination call from being assigned to the landing call. Thus, the elevator group management system 100 can suppress a large number of users from boarding the car responding to the landing destination call at the boarding floor of the landing call, and suppress the decrease in convenience of the user who registered the landing destination call.

[0058] Further, the notification section 14 notifies at least one of the user who registered the hall call or the hall destination call and is waiting at the boarding floor, and the user who has boarded the car, of the stop factor as a factor of the car stopping, by the stop factor. By being configured as described above, the elevator group management system 100 is able to notify the user who registered the hall call and is waiting at the boarding floor, for example, of the case where the car that stops at the boarding floor next stops at the boarding floor where the user who registered the hall call is waiting, as the boarding floor of the hall destination call. Thus, the elevator group management system 100 is able to suppress the user who registered the hall call and is waiting at the boarding floor from boarding the car that is responding to the hall destination call by mistake. Further, the elevator group management system 100 is able to notify the user who registered the hall destination call and boarded the car that is responding to the hall destination call, for example, of the boarding floor of the hall call that stops at a different floor from the destination floor of the hall destination call before reaching the destination floor. Thus, the elevator group management system 100 is able to suppress the user who registered the hall destination call and boarded the car that is responding to the hall destination call from alighting at a different floor before reaching the destination floor of the hall destination call.

[0059] Embodiment 2

[0060] The elevator group management system 101 in Embodiment 2 will be described. The elevator group management system 100 of Embodiment 1 is a structure that suppresses the case where a large number of users board the car that is responding to the hall destination call in the boarding floor of the hall call when the registration of the hall call is newly accepted while the car that is responding to the hall destination call is decided to move to the boarding floor of the hall destination call. The elevator group management system 101 of Embodiment 2 suppresses the case where a large number of users board the car that is responding to the hall destination call in the boarding floor of the hall call when the registration of the hall destination call is newly accepted while the car that is responding to the hall call is decided to move to the boarding floor of the hall call, unlike the elevator group management system 100 of Embodiment 1. The same reference numerals are attached to the same structures as those of Embodiment 1. Further, detailed description of the structures common to Embodiment 1 will be omitted, and mainly the structures different from Embodiment 1 will be described.

[0061] In Embodiment 2, in a case where the registration of a new hall destination call is accepted while it is decided that the car responding to the hall call moves to the boarding floor of the hall call, the reception unit 11 measures an elapsed time from when the hall call is accepted to when the new hall destination call is accepted. Further, the arrival prediction time calculation unit calculates an arrival prediction time from when the registration of the hall destination call is accepted to when the user boards at the boarding floor of the hall call and arrives at the boarding floor of the hall destination call. Then, the decision unit 13 calculates a total time obtained by adding the elapsed time received from the reception unit 11 to the arrival prediction time received from the arrival prediction time calculation unit. The decision unit 13 can regard the total time as an arrival prediction time from when the registration of the hall call is accepted to when the car arrives at the boarding floor of the hall destination call. Therefore, the decision unit 13 compares the total time with a threshold set in advance, whereby it can estimate whether a large number of users board at the boarding floor of the hall call before arriving at the boarding floor of the hall destination call, based on the arrival prediction time from when the registration of the hall call is accepted to when the user boards at the boarding floor of the hall call and arrives at the boarding floor of the hall destination call in a case where the car responding to the hall call responds to the new hall destination call.

[0062] The processing flow of the elevator group management system 101 in Embodiment 2 will be described. Figure 5 is a flowchart illustrating the processing flow of the elevator group management system 101 in Embodiment 2. Further, Figure 6 illustrates the processing flow of the elevator group management system 101 in a case where the registration of a new hall destination call is accepted while it is decided that the car responding to the hall call moves to the boarding floor of the hall call. Further, Figure 6 is a specific example of the processing of the elevator group management system 101 in Embodiment 2. In Figure 6 , the elevator group has the car A, the car B, and the car C, and the car A and the car B can operate with each other on the 1st floor to the 10th floor. Further, the car C can operate on the 1st floor, the 8th floor to the 10th floor, and cannot operate on the 2nd floor to the 7th floor. Further, in Figure 6 , the car A is located on the 7th floor and moves to the registered hall call boarding floor, i.e., the 5th floor. Further, a case is illustrated where the car A is located on the 9th floor and passes through the 7th floor in the process of moving to the hall call boarding floor, i.e., the 5th floor, at the time when the hall call of the 5th floor is registered. Further, in Figure 6 , it is assumed that the car B is located on the 8th floor and moves to the registered hall call destination floor, i.e., the 9th floor, and the user who boards the car B alights at the 9th floor. Further, the car C is located on the 10th floor. Further, in Figure 6 , a new hall destination call is registered in which the 3rd floor is designated as the boarding floor and the 1st floor is designated as the destination floor.

[0063] In step S201, the reception part 11 receives registration of a new landing destination call from a user. At this time, the reception part 11 acquires information of a boarding floor at which the user boards a car, a destination floor at which the user gets off the car, and a direction of up or down floors from the boarding floor to the destination floor, and transmits the acquired information to the decision part 13. For example, in the case where the user boards the car at the 3rd floor, gets off the car at the 1st floor, and moves in the down direction from the 3rd floor to the 1st floor, the reception part 11 acquires information that the boarding floor is the 3rd floor, information that the destination floor is the 1st floor, and information that the direction of up or down floors is the down direction. Figure 6 In the case where the user boards the car at the 3rd floor, gets off the car at the 1st floor, and moves in the down direction from the 3rd floor to the 1st floor, the reception part 11 acquires information that the boarding floor is the 3rd floor, information that the destination floor is the 1st floor, and information that the direction of up or down floors is the down direction.

[0064] In step S202, the decision part 13 receives information on intervals in which each car can run from the storage part 15, and extracts assignment candidates of cars that can respond to the new landing destination call. For example, in the case where the car A and the car B can run on the 1st to 10th floors, and the car C cannot run on the 2nd to 7th floors, the decision part 13 extracts the car A and the car B as assignment candidates of cars that can respond to the new landing destination call. Figure 6 In the case where the car A and the car B can run on the 1st to 10th floors, and the car C cannot run on the 2nd to 7th floors, the decision part 13 extracts the car A and the car B as assignment candidates of cars that can respond to the new landing destination call.

[0065] In step S203, the decision part 13 acquires landing call information of a landing call that has been registered from the storage part 15, and extracts a car that has been decided to respond to a landing call and move to a boarding floor of the landing call, among the assignment candidates of cars that can respond to the new landing destination call. For example, in the case where the car A has been decided to respond to a landing call and move to the 5th floor that is a boarding floor of the landing call, the decision part 13 extracts the car A. Figure 6 In the case where the car A has been decided to respond to a landing call and move to the 5th floor that is a boarding floor of the landing call, the decision part 13 extracts the car A.

[0066] In step S204, the decision part 13 judges whether there is a car that moves in the same direction as a direction in which the car that has moved to the boarding floor of the landing call moves, in the direction of up or down floors from a boarding floor designated in the new landing destination call to a destination floor, with respect to the car that has moved to the boarding floor of the landing call, which is extracted. For example, in the case where the car A moves in the down direction, and the direction of up or down floors from the boarding floor designated in the new landing destination call to the destination floor is the down direction, the decision part 13 judges that the directions are the same. Figure 6 In the case where the car A moves in the down direction, and the direction of up or down floors from the boarding floor designated in the new landing destination call to the destination floor is the down direction, the decision part 13 judges that the directions are the same.

[0067] In the case where there is a car that satisfies the condition of step S204 (step S204: Yes), in step S205, the arrival prediction time calculation part 12 calculates an arrival prediction time from when the registration of the landing destination call is received to when the user boards the car at the boarding floor of the landing call and arrives at the boarding floor of the landing destination call, with respect to the car. For example, in the case where the car A moves in the down direction, and the direction of up or down floors from the boarding floor designated in the new landing destination call to the destination floor is the down direction, the decision part 13 judges that the directions are the same. Figure 6In the example shown in FIG204 , the estimated arrival time calculation unit 12 calculates the estimated arrival time from the time a new landing destination call for the 3rd floor is received until the time the user boards car A on the 5th floor and arrives at the 3rd floor. If there is no car that meets the conditions of step S204 (step S204: No), the process proceeds to step S208.

[0068] In step S206, the decision unit 13 receives from the reception unit 11 the elapsed time from when the landing call was received to when the new landing destination call is received. Figure 6 In , the decision unit 13 receives from the reception unit 11 the elapsed time from when the landing call of the 5th floor is received to when the new landing destination call of the 3rd floor is received. Figure 6 In the case of receiving a landing call on the 5th floor, it means that car A is on the 9th floor. Figure 6 In the example, when the new landing destination call for the 3rd floor is accepted, it means that car A passes the 7th floor while moving from the 9th floor to the 5th floor, the boarding floor for the landing call. In addition, the decision unit 13 receives the arrival prediction time calculated by the arrival prediction time calculation unit 12 in step S205 from the arrival prediction time calculation unit 12. Then, for the cars that meet the conditions of step S204, the decision unit 13 calculates the total time obtained by adding the elapsed time received from the acceptance unit 11 and the arrival prediction time calculated by the arrival prediction time calculation unit 12 in step S205, and determines whether there is a car for which the total time is greater than a preset threshold. That is, the decision unit 13 regards the total time as the arrival prediction time from the time the landing call registration is accepted to the time when the user gets on the boarding floor for the landing call, i.e., the 5th floor, and arrives at the boarding floor for the new landing destination call, i.e., the 3rd floor, and determines whether there is a car for which the total time is greater than the preset threshold.

[0069] As in the first embodiment, the preset threshold value with which the total time obtained by adding the elapsed time calculated by the determination unit 13 to the predicted arrival time is compared in step S206 is appropriately set to an arbitrary value.

[0070] If there is a car whose total time calculated in step S206 is equal to or greater than a preset threshold value (step S206: Yes), in step S207, the decision unit 13 determines to implement exclusion control for not determining the car currently responding to the landing call as the car responding to the new landing destination call. Figure 7In this case, the decision section 13 determines that the exclusion control is implemented in which the car A is not decided as the car responding to the new hall destination call registered at the 3rd floor, in a case where the total time obtained by adding the elapsed time from when the car A is located at the 9th floor and the hall call for the 5th floor is accepted until when the new hall destination call for the 7th floor and the 3rd floor is accepted and the arrival prediction time from when the new hall destination call for the 7th floor and the 3rd floor is accepted until when the user gets on the car A at the 5th floor and arrives at the 3rd floor calculated in step S206 is more than the threshold value set in advance. Further, in a case where there is no car in which the total time is more than the threshold value set in advance (step S206: No), the process proceeds to step S208.

[0071] In step S208, the decision section 13 decides the car in which the arrival prediction time calculated by the arrival prediction time calculation section 12 is the smallest, on the basis of the cars in which the exclusion control is not implemented in which the car is not decided as the car responding to the new hall destination call, among the distribution candidates in which the car responding to the new hall destination call can be allocated, which is determined in step S207. For example, in a case where the car A and the car B are the distribution candidates in which the car responding to the new hall destination call can be allocated, the decision section 13 decides the car B as the distribution number of the car responding to the new hall destination call, in a case where the car A is determined in step S207 to implement the exclusion control in which the car is not decided as the car responding to the new hall destination call registered at the 3rd floor. Figure 7 In this case, the decision section 13 determines that the exclusion control is implemented in which the car A is not decided as the car responding to the new hall destination call registered at the 3rd floor, in a case where the total time obtained by adding the elapsed time from when the car A is located at the 9th floor and the hall call for the 5th floor is accepted until when the new hall destination call for the 7th floor and the 3rd floor is accepted and the arrival prediction time from when the new hall destination call for the 7th floor and the 3rd floor is accepted until when the user gets on the car A at the 5th floor and arrives at the 3rd floor calculated in step S206 is more than the threshold value set in advance. Further, in a case where there is no car in which the total time is more than the threshold value set in advance (step S206: No), the process proceeds to step S208.

[0072] The above completes the explanation of the process flow of the elevator group management system 101 in Embodiment 2.

[0073] Thus, the elevator group management system 101 in Embodiment 2 has the decision section 13 that, when it is decided that the car responding to the hall call moves to the boarding floor of the hall call, in a case where registration of a hall destination call is newly accepted, judges whether or not the total time obtained by adding the elapsed time from when the registration of the hall call was accepted to when the registration of the hall destination call was accepted and the arrival prediction time from when the registration of the hall destination call was accepted to when the user boards the car at the boarding floor of the hall call and arrives at the boarding floor of the hall destination call is equal to or more than a threshold value set in advance, and, in a case where the total time is equal to or more than the threshold value, judges that the exclusion control of deciding that the car that is responding to the hall call is not the car that responds to the hall destination call is not performed, and decides the car that responds to the new hall destination call from among the allocation candidates on the basis of excluding the car. By being configured as described above, the elevator group management system 101 can suppress the car that is responding to the hall call from being allocated to the hall destination call, even though it can be estimated that the arrival prediction time from when the registration of the hall call was accepted to when the user boards the car at the boarding floor of the hall call and arrives at the boarding floor of the hall destination call is long, and a large number of users board the car at the boarding floor of the hall call before arriving at the boarding floor of the hall destination call. Thus, the elevator group management system 101 can suppress a large number of users from boarding the car that responds to the hall destination call at the boarding floor of the hall call, and suppress a decrease in convenience of the user who registered the hall destination call.

[0074] In addition, the decision section 13 judges whether or not there is a car for which the total time obtained by adding the elapsed time from when the registration of the hall call was accepted to when the registration of the new hall destination call was accepted and the arrival prediction time from when the registration of the hall destination call was accepted to when the user boards the car at the boarding floor of the hall call and arrives at the boarding floor of the hall destination call is equal to or more than a threshold value set in advance, but is not limited thereto. That is, the decision section 13 can calculate only the arrival prediction time from when the registration of the hall call was accepted to when the user boards the car at the boarding floor of the hall call and arrives at the boarding floor of the new hall destination call. For example, in a case where the hall call is a call for a floor that is the same as the boarding floor of the hall destination call, the decision section 13 can calculate only the arrival prediction time from when the registration of the hall call was accepted to when the user boards the car at the boarding floor of the hall call and arrives at the boarding floor of the hall destination call. Figure 8In this case, the decision unit 13 can also calculate a total time obtained by adding the arrival prediction time from when the car A located at the 9th floor has accepted the registration of the hall call to the arrival at the boarding floor of the hall call, i.e., the 5th floor, to the arrival prediction time from when the car A has arrived at the boarding floor of the hall call, i.e., the 5th floor, to the arrival at the boarding floor of the new hall destination call, i.e., the 3rd floor, by the user at the boarding floor of the hall call, i.e., the 5th floor, to the car A, and then the decision unit 13 can also regard the total time as the arrival prediction time from when the registration of the hall call has been accepted to the boarding of the car A at the boarding floor of the hall call, i.e., the 5th floor, and the arrival of the car A at the boarding floor of the new hall destination call, i.e., the 3rd floor, for the car A located at the 9th floor.

[0075] Embodiment 3

[0076] The elevator group management system 102 in Embodiment 3 will be described. The elevator group management system 102 of Embodiment 3 differs from the elevator group management system 100 of Embodiment 1 in that the exclusion control of not deciding the car responding to the hall destination call as the car responding to the hall call is implemented in the case where there is a boarding floor of the hall call in the section from the boarding floor of the hall destination call to the destination floor of the hall destination call when the registration of the hall call is newly accepted after it is decided that the car responding to the hall destination call moves to the boarding floor of the hall destination call. The same reference numerals are attached to the same structures as those of Embodiment 1. Moreover, the detailed description of the same structures as those of Embodiment 1 will be omitted, and the structures different from those of Embodiment 1 will mainly be described.

[0077] The processing flow of the elevator group management system 102 in Embodiment 3 will be described. Figure 8 is a flowchart showing the processing flow of the elevator group management system 102 of Embodiment 3. Moreover, Figure 8 shows the processing flow of the elevator group management system 102 in the case where the registration of the hall call is newly accepted after it is decided that the car responding to the hall destination call moves to the boarding floor of the hall destination call. Moreover, Figure 8 is a specific example of the processing of the elevator group management system 102 in Embodiment 3. In Figure 8 In this case, the elevator group has the car A, the car B, and the car C, and the car A and the car B can move between the 1st floor and the 10th floor. Moreover, the car C can move between the 1st floor, the 8th floor, and the 10th floor, and cannot move between the 2nd floor and the 7th floor. Moreover, in Figure 8 In this case, the car A is located at the 6th floor, and moves to the registered boarding floor of the hall destination call, i.e., the 4th floor. Moreover, the destination floor of the registered hall destination call is the 4th floor. Moreover, in Figure 8 In this case, the car B is located at the 9th floor, and the car C is located at the 10th floor. Moreover, in Figure 8In the case where the direction of the new hall call is the down direction, the hall call is registered in the 3rd floor. In addition, steps S306 to S310 are the same as steps S104 to S108 of Embodiment 1, and thus detailed description is omitted.

[0078] In step S301, the reception part 11 receives registration of a new hall call from a user. At this time, the reception part 11 acquires information of a floor on which the user boards a car and a direction of up or down floors from the boarding floor to a destination floor, and transmits the acquired information to the decision part 13. For example, in the case where the user boards the car on the 3rd floor and the direction of up or down floors from the boarding floor to the destination floor is the down direction, the reception part 11 acquires information that the boarding floor of the user is the 3rd floor and the direction of up or down floors from the boarding floor to the destination floor is the down direction. Figure 8 In the case where the direction of the new hall call is the down direction, the hall call is registered in the 3rd floor. In addition, steps S306 to S310 are the same as steps S104 to S108 of Embodiment 1, and thus detailed description is omitted.

[0079] In step S302, the decision part 13 receives information on intervals in which each car can run from the storage part 15, and extracts assignment candidates of cars that can respond to the new hall call. For example, in the case where the car A and the car B can run on the 1st to 10th floors and the car C cannot run on the 2nd to 7th floors, the decision part 13 extracts the car A and the car B as assignment candidates of cars that can respond to the new hall call. Figure 8 In the case where the direction of the new hall call is the down direction, the hall call is registered in the 3rd floor. In addition, steps S306 to S310 are the same as steps S104 to S108 of Embodiment 1, and thus detailed description is omitted.

[0080] In step S303, the decision part 13 acquires hall destination call information of a hall destination call that has been registered from the storage part 15, and extracts, among the assignment candidates of cars that can respond to the new hall call, a car that has been decided to respond to a hall destination call and move to a boarding floor of the hall destination call. For example, in the case where the car A moves to the 4th floor that is the boarding floor of the registered hall destination call, the decision part 13 extracts the car A. Figure 9 In the case where the direction of the new hall call is the down direction, the hall call is registered in the 3rd floor. In addition, steps S306 to S310 are the same as steps S104 to S108 of Embodiment 1, and thus detailed description is omitted.

[0081] In step S304, the decision part 13 determines, with respect to the car that moves to the boarding floor of the hall destination call, whether there is a boarding floor of the new hall call in an interval from the boarding floor of the hall destination call to a destination floor of the hall destination call. For example, in the case where the car A moves to the 4th floor that is the boarding floor of the registered hall destination call, the decision part 13 determines that there is the 3rd floor that is the boarding floor of the new hall call in an interval from the 4th floor that is the boarding floor of the hall destination call to the 1st floor that is the destination floor of the hall destination call. Figure 9 In the case where the direction of the new hall call is the down direction, the hall call is registered in the 3rd floor. In addition, steps S306 to S310 are the same as steps S104 to S108 of Embodiment 1, and thus detailed description is omitted.

[0082] In step S305, the decision part 13 determines, with respect to the car that moves to the boarding floor of the hall destination call, that the exclusion control of not deciding the car that is responding to the hall destination call as a car that responds to the new hall call is performed, in the case where there is a boarding floor of the new hall call in an interval from the boarding floor of the hall destination call to a destination floor of the hall destination call (step S304: Yes), and proceeds to step S310. For example, in the case where the car A moves to the 4th floor that is the boarding floor of the registered hall destination call and there is the 3rd floor that is the boarding floor of the new hall call in an interval from the 4th floor that is the boarding floor of the hall destination call to the 1st floor that is the destination floor of the hall destination call, the decision part 13 determines that the exclusion control is performed.Figure 9 In this case, the decision unit 13 determines to implement the exclusion control that does not decide the car A as the car responding to the new hall call registered at the 3rd floor. Further, in a case where there is no boarding floor of a new hall call in the zone from the boarding floor of the hall destination call to the destination floor of the hall destination call (step S304: No), the process proceeds to step S306.

[0083] Thus, the process flow for the elevator group management system 102 in Embodiment 3 is explained.

[0084] As with Embodiment 1, the elevator group management system 102 in Embodiment 3 has the decision unit 13 that, in a case where the registration of a hall call is newly accepted while the car responding to the hall destination call is decided to move to the boarding floor of the hall destination call, determines to implement the exclusion control that does not decide the car responding to the hall destination call as the car responding to the hall call in a case where the arrival prediction time from when the registration of the hall call is accepted until the user boards at the boarding floor of the hall call and arrives at the boarding floor of the hall destination call is equal to or longer than a threshold value set in advance, and decides the car responding to the new hall call from the allocation candidates on the basis of the exclusion of the car. With the above-described configuration, the elevator group management system 102 can suppress the car responding to the hall destination call from being allocated to the hall call, even though it can be estimated that the arrival prediction time from when the registration of the hall call is accepted until the user boards at the boarding floor of the hall call and arrives at the boarding floor of the hall destination call is long, and a large number of users board at the boarding floor of the hall call before arriving at the boarding floor of the hall destination call, with respect to the car responding to the hall destination call. Thus, the elevator group management system 102 can suppress a large number of users from boarding on the car responding to the hall destination call at the boarding floor of the hall call, and suppress the decrease in convenience of the user who registered the hall destination call.

[0085] Further, the decision section 13 in Embodiment 3, in a case where the registration of a hall call is newly accepted while it is decided that the car responding to the landing destination call moves to the landing floor of the landing destination call, determines that the exclusion control of not deciding the car responding to the landing destination call as the car responding to the hall call is implemented, in a case where the landing floor of the hall call exists in the zone from the landing floor of the landing destination call to the destination floor of the landing destination call. By being configured as described above, the elevator group management system 102 can suppress a case where a user boards the car responding to the landing destination call at the landing floor of the hall call in the zone from the landing floor of the landing destination call to the destination floor of the landing destination call. Thus, the elevator group management system 102 can suppress a case where the user who registered the landing destination call rides in the car, reaches the destination floor of the landing destination call before reaching the destination floor of the hall call, and the like, thereby reducing the convenience of the user who registered the landing destination call.

[0086] Here, in a case where the exclusion control of not deciding the car responding to the landing destination call as the car responding to the new hall call is implemented in step S305, it can be considered that the car that reached the destination floor of the landing destination call after responding to the landing destination call is decided as the car responding to the new hall call. However, the more the number of floors in the zone from the destination floor of the landing destination call to the landing floor of the new hall call, the higher the possibility that the car responds to another new landing destination call or hall call in the zone. In this case, the waiting time of the user who registered the new hall call at the landing floor becomes longer, and the convenience of the user who registered the new hall call can be reduced. Therefore, in a case where the number of floors from the destination floor of the landing destination call to the landing floor of the hall call is equal to or more than a threshold value set in advance, the decision section 13 can also implement the exclusion control of not deciding the car that reached the destination floor of the landing destination call after responding to the landing destination call as the car responding to the hall call.

[0087] The use Figure 9 will be specifically described. Figure 9 is another specific example of the process of the elevator group management system 102 in Embodiment 3. In Figure 9 , the elevator group has a car A and a car B, and the car A and the car B can operate between the 1st floor to the 10th floor. Further, in Figure 9 , the car A is located at the 7th floor, and moves to the registered landing destination call landing floor, i.e., the 5th floor. Further, the destination floor of the registered landing destination call is the 1st floor. Further, in Figure 9In this case, the car B is located at the 9th floor, and moves to the registered landing call floors, i.e., the 8th floor and the 6th floor. In addition, in this case, a new landing call in the specified downward direction is registered at the 4th floor. Furthermore, the pre-set threshold value, which is compared with the number of floors from the destination floor of the landing destination call to the boarding floor of the landing call, is 2. Figure 10 In this case, a new landing call in the specified downward direction is registered at the 4th floor. Furthermore, the pre-set threshold value, which is compared with the number of floors from the destination floor of the landing destination call to the boarding floor of the landing call, is 2.

[0088] In this case, the decision section 13 determines that the car A is the car that responds to the new landing call registered at the 4th floor, and the car B is the car that does not respond to the new landing call registered at the 4th floor. In this case, the car B is located at the 9th floor, and moves to the registered landing call floors, i.e., the 8th floor and the 6th floor. In addition, in this case, a new landing call in the specified downward direction is registered at the 4th floor. Furthermore, the pre-set threshold value, which is compared with the number of floors from the destination floor of the landing destination call to the boarding floor of the landing call, is 2. Figure 10 In this case, the decision section 13 determines that the car A is the car that responds to the new landing call registered at the 4th floor, and the car B is the car that does not respond to the new landing call registered at the 4th floor. In this case, the car B is located at the 9th floor, and moves to the registered landing call floors, i.e., the 8th floor and the 6th floor. In addition, in this case, a new landing call in the specified downward direction is registered at the 4th floor. Furthermore, the pre-set threshold value, which is compared with the number of floors from the destination floor of the landing destination call to the boarding floor of the landing call, is 2.

[0089] In this case, the decision section 13 determines that the car A is the car that responds to the new landing call registered at the 4th floor, and the car B is the car that does not respond to the new landing call registered at the 4th floor. In this case, the car B is located at the 9th floor, and moves to the registered landing call floors, i.e., the 8th floor and the 6th floor. In addition, in this case, a new landing call in the specified downward direction is registered at the 4th floor. Furthermore, the pre-set threshold value, which is compared with the number of floors from the destination floor of the landing destination call to the boarding floor of the landing call, is 2. Figure 10 In this case, the decision section 13 determines that the car A is the car that responds to the new landing call registered at the 4th floor, and the car B is the car that does not respond to the new landing call registered at the 4th floor. In this case, the car B is located at the 9th floor, and moves to the registered landing call floors, i.e., the 8th floor and the 6th floor. In addition, in this case, a new landing call in the specified downward direction is registered at the 4th floor. Furthermore, the pre-set threshold value, which is compared with the number of floors from the destination floor of the landing destination call to the boarding floor of the landing call, is 2.

[0090] Furthermore, in the above case, the pre-set threshold value, which is compared with the number of floors from the destination floor of the landing destination call to the boarding floor of the new landing call, is appropriately set to an arbitrary value. For example, the decision section 13 can set the threshold value in accordance with the characteristics of the user who registered the landing destination call, or the like. As described above, the characteristics of the user are, for example, whether or not a wheelchair is used, whether or not a baby carriage is used, whether or not goods are carried, age, or the like.

[0091] For example, if the user who has registered a landing destination call is a wheelchair user, it takes time for the user to board and disembark, which increases the waiting time for users waiting at the boarding floor of the new landing call. Therefore, the decision unit 13 may set a smaller threshold for comparison with the number of floors from the boarding floor of the new landing call to the destination floor of the landing destination call. This allows the elevator group management system 102 to prevent the situation in which the waiting time at the boarding floor of the user who has registered the new landing call increases, thereby reducing the convenience for the user who has registered the new landing call.

[0092] Implementation method 4.

[0093] The elevator group management system 103 in Embodiment 4 will be described. The elevator group management system 103 in Embodiment 4 differs from the elevator group management system 100 in Embodiment 1 in that it includes a landing destination call occupancy rate calculation unit 19. This landing destination call occupancy rate calculation unit 19 calculates the landing destination call occupancy rate for a plurality of cars, i.e., the landing destination call occupancy rate, based on at least one of the number of cars that have responded to registered landing destination calls and the number of floors from the boarding floor of the registered landing destination call to the destination floor. The same reference numerals are used for the same components as in Embodiment 1. Detailed description of the components identical to those in Embodiment 1 will be omitted, and the components different from Embodiment 1 will be primarily described.

[0094] use Figure 11 , explaining the elevator group management system 103 in embodiment 4. Figure 11 : is a structural diagram of the elevator group management system 103 of embodiment 4. Figure 11 As shown, the elevator group management system 103 in the fourth embodiment includes a landing destination call occupancy rate calculation unit 19 .

[0095] The landing destination call occupancy rate calculation unit 19 receives information from the storage unit 15 regarding the number of cars that respond to registered landing destination calls, the number of floors from the boarding floor of the registered landing destination call to the destination floor, the number of installed elevators, and the sections in which each car can operate. The landing destination call occupancy rate calculation unit 19 calculates the landing destination call occupancy rate of the plurality of cars, i.e., the landing destination call occupancy rate, based on at least one of the number of cars that respond to registered landing destination calls and the number of floors from the boarding floor of the registered landing destination call to the destination floor, among the information received from the storage unit 15. The landing destination call occupancy rate calculation unit 19 transmits the calculated landing destination call occupancy rate to the determination unit 13.

[0096] also, Figure 11is a specific example of the process of the elevator group management system 103 in Embodiment 4. In Figure 11 the elevator group has the car A, the car B, and the car C. Further, the car A and the car B can operate between the 1st floor and the 10th floor. Further, the car C can operate between the 1st floor, the 8th floor to the 10th floor, and cannot operate between the 2nd floor and the 7th floor. Further, in Figure 11 the car A is located at the 1st floor in response to a registered hall destination call in which the boarding floor is set to the 3rd floor and the destination floor is set to the 10th floor. Further, in Figure 11 the car B is located at the 9th floor in response to a registered hall destination call in which the boarding floor is set to the 7th floor and the destination floor is set to the 2nd floor. Further, the car C is located at the 10th floor. Further, in Figure 11 a new hall call in which the downward direction is designated is registered at the 6th floor.

[0097] As described above, the hall destination call occupancy rate calculating section 19 can also calculate the hall destination call occupancy rate in accordance with the number of cars in response to the registered hall destination call. In Figure 11 the number of set cars is three, the car A, the car B, and the car C, and in contrast, the number of cars in response to the registered hall destination call is two, the car A and the car B, and therefore, the hall destination call occupancy rate calculating section 19 calculates that the hall destination call occupancy rate in the plurality of cars is 67%.

[0098] Further, as described above, the hall destination call occupancy rate calculating section 19 can also calculate the hall destination call occupancy rate in accordance with the number of floors from the boarding floor to the destination floor of the registered hall destination call. In Figure 11 the number of floors from the boarding floor to the destination floor of the registered hall destination call with respect to the car A, which can operate, that is, the 10th floor, is seven, and therefore, the hall destination call occupancy rate calculating section 19 calculates that the hall destination call occupancy rate of the car A is 70%. Further, the number of floors from the boarding floor to the destination floor of the registered hall destination call with respect to the car B, which can operate, that is, the 10th floor, is five, and therefore, the hall destination call occupancy rate calculating section 19 calculates that the hall destination call occupancy rate of the car B is 50%. Further, the car C does not respond to the hall destination call, and therefore, the hall destination call occupancy rate calculating section 19 calculates that the hall destination call occupancy rate of the car C is 0%. Then, the hall destination call occupancy rate calculating section 19 calculates 40%, which is the average of the hall destination call occupancy rates of the car A, the car B, and the car C, as the hall destination call occupancy rate in the plurality of cars.

[0099] Further, the hall destination call occupancy rate calculating section 19 does not need to calculate the hall destination call occupancy rate of each car. For example, in Figure 11In this case, the hall destination call occupancy rate calculating section 19 can also total the sections in which the car A, the car B, and the car C can run, and set the total to the sections in which the elevator group can run. Figure 12 In this case, the car A and the car B can run from the 1st floor to the 10th floor. The car C can run from the 1st floor, the 8th floor to the 10th floor, and thus the total of the sections in which the car A, the car B, and the car C can run is 24 floors. Further, in this case, the number of floors from the boarding floor of the hall destination call to the destination floor of the car A is 7 floors, and the number of floors from the boarding floor of the hall destination call to the destination floor of the car B is 5 floors. Figure 12 In this case, the number of floors from the boarding floor of the hall destination call to the destination floor of the car A is 7 floors, and the number of floors from the boarding floor of the hall destination call to the destination floor of the car B is 5 floors. Since the total of the number of floors from the boarding floor of the hall destination call to the destination floor of the car A and the car B is 12 floors with respect to the total of the sections in which the car A, the car B, and the car C can run, which is 24 floors, the hall destination call occupancy rate calculating section 19 calculates that the hall destination call occupancy rate in the plurality of cars is 50%.

[0100] Further, the hall destination call occupancy rate calculating section 19 can also calculate the hall destination call occupancy rate based on the number of cars responding to the registered hall destination call and the hall destination call occupancy rate based on the number of floors from the boarding floor of the registered hall destination call to the destination floor, respectively. In this case, the decision section 13 can also compare the hall destination call occupancy rate based on the number of cars responding to the registered hall destination call and the hall destination call occupancy rate based on the number of floors from the boarding floor of the registered hall destination call to the destination floor with the threshold value set in advance, respectively. For example, in the case where the hall destination call occupancy rate based on the number of cars responding to the registered hall destination call is 67% and the hall destination call occupancy rate based on the number of floors from the boarding floor of the registered hall destination call to the destination floor is the average of the hall destination call occupancy rates of the car A, the car B, and the car C, which is 40%, the decision section 13 can compare the hall destination call occupancy rates with the threshold value set in advance, respectively. Figure 13 Further, the hall destination call occupancy rate calculating section 19 can also calculate the hall destination call occupancy rate based on the number of cars responding to the registered hall destination call and the hall destination call occupancy rate based on the number of floors from the boarding floor of the registered hall destination call to the destination floor, respectively. In this case, the decision section 13 can also compare the hall destination call occupancy rate based on the number of cars responding to the registered hall destination call and the hall destination call occupancy rate based on the number of floors from the boarding floor of the registered hall destination call to the destination floor with the threshold value set in advance, respectively. For example, in the case where the hall destination call occupancy rate based on the number of cars responding to the registered hall destination call is 67% and the hall destination call occupancy rate based on the number of floors from the boarding floor of the registered hall destination call to the destination floor is the average of the hall destination call occupancy rates of the car A, the car B, and the car C, which is 40%, the decision section 13 can compare the hall destination call occupancy rates with the threshold value set in advance, respectively.

[0101] Next, the processing flow of the elevator group management system 103 in Embodiment 4 will be described. Figure 13 is a flowchart showing the processing flow of the elevator group management system 103 in Embodiment 4. Since the steps S401 to S403 and the steps S406 to S412 are the same as the steps S301 to S310 in Embodiment 3, detailed description will be omitted.

[0102] In step S404, the hall destination call occupancy rate calculating section 19 calculates an occupancy rate of the hall destination calls, i.e., a hall destination call occupancy rate, in the plurality of cars, based on at least one of the number of cars responding to the hall destination calls that have been registered and the number of floors from the floor on which the car responding to the hall destination call has stopped to the destination floor. The hall destination call occupancy rate calculating section 19 transmits the calculated hall destination call occupancy rate to the decision section 13.

[0103] In step S405, the decision section 13 determines whether the hall destination call occupancy rate received from the hall destination call occupancy rate calculating section 19 is equal to or greater than a predetermined threshold value. In the case where the hall destination call occupancy rate is equal to or greater than the predetermined threshold value (step S405: YES), the decision section 13 determines that the exclusion control is not implemented and proceeds to step S412. Further, in the case where the hall destination call occupancy rate received from the hall destination call occupancy rate calculating section 19 is less than the predetermined threshold value (step S405: NO), the decision section 13 proceeds to step S406.

[0104] The above completes the explanation of the processing flow of the elevator group management system 103 in Embodiment 4.

[0105] As with Embodiment 1, the elevator group management system 103 in Embodiment 4 has the decision section 13 that, in the case where the registration of the hall call is newly accepted while it is determined that the car responding to the hall destination call has moved to the floor on which the hall call is registered, determines that the exclusion control is implemented in the case where the arrival prediction time from when the registration of the hall call is accepted until the user boards the car at the floor on which the hall call is registered and arrives at the floor on which the hall destination call is registered is equal to or greater than a predetermined threshold value, and determines the car responding to the new hall call from among the allocation candidates on the basis of excluding the car responding to the hall destination call. With the above-described configuration, the elevator group management system 103 can suppress the car responding to the hall destination call from being allocated to the hall call, even though it is estimated that the arrival prediction time from when the registration of the hall call is accepted until the user boards the car at the floor on which the hall call is registered and arrives at the floor on which the hall destination call is registered is long and a large number of users board the car at the floor on which the hall call is registered before arriving at the floor on which the hall destination call is registered. Thus, the elevator group management system 103 can suppress a large number of users from boarding the car responding to the hall destination call at the floor on which the hall call is registered and suppress the decrease in convenience of the user who has registered the hall destination call.

[0106] Further, the elevator group management system 103 in Embodiment 4 also has a hall destination call occupancy rate calculating section 19 that calculates a hall destination call occupancy rate, which is an occupancy rate of hall destination calls in the plurality of cars, from at least one of the number of cars that have responded to the hall destination call that has been registered and the number of floors from the boarding floor of the hall destination call that has been registered to the destination floor. Further, in a case where the hall destination call occupancy rate is equal to or higher than a threshold value that is set in advance, the decision section 13 of Embodiment 4 determines that the exclusion control is not implemented. By being configured as described above, the elevator group management system 103 is able to determine whether or not to continue maintaining the exclusion control for avoiding competition between the hall destination call and the hall call. Thereby, the elevator group management system 103 is able to suppress a case where the hall destination call is excessively favored due to suppression of allocation to the hall call for the hall destination call response panel, and thereby the operation efficiency of the elevator group is reduced.

[0107] In addition, in Figure 13 , a case where registration of a hall call is accepted while it is determined that the car that has responded to the hall destination call moves to the boarding floor of the hall destination call is illustrated, but is not limited thereto. For example, in a case where registration of a new hall destination call is accepted while it is determined that the car that has responded to the hall call moves to the boarding floor of the hall call, the hall destination call occupancy rate calculating section 19 is also able to calculate the hall destination call occupancy rate in the same manner. In this case, the hall destination call occupancy rate calculating section 19 adds hall destination call information in a case where the new hall destination call is responded to to the hall destination call information before the new hall destination call is responded to, and calculates the hall destination call occupancy rate.

[0108] The use Figure 13 will be described in detail. Figure 13 is another specific example of the process of the elevator group management system 103 in Embodiment 4. In Figure 13 , the elevator group has a car A and a car B. Further, the car A is able to operate on floors 1 to 10. Further, the car B is able to operate on floors 1, 8 to 10, and is not able to operate on floors 2 to 7. Further, in Figure 13 , the car A is located on floor 1. Further, in ​ , the car B is located on floor 10. Further, in ​ , a new hall destination call is registered in which a boarding floor is designated as floor 3 and a destination floor is designated as floor 10. For example, in ​In this case, neither car A nor car B responds to the hall destination call, and therefore, the hall destination call occupancy rate calculating section 19 calculates the hall destination call occupancy rate before the new hall destination call as 0%. Then, since the number of floors from the boarding floor of the hall destination call to the destination floor with respect to the section in which car A can run, i.e., the 10th floor, is 7 floors in the case where car A responds to the new hall destination call, the hall destination call occupancy rate calculating section 19 calculates the hall destination call occupancy rate of car A as 70%. Further, since car B does not respond to the hall destination call, the hall destination call occupancy rate calculating section 19 calculates the hall destination call occupancy rate of car B as 0%. Then, the hall destination call occupancy rate calculating section 19 calculates the average of the hall destination call occupancy rates of car A and car B, i.e., 45%, as the hall destination call occupancy rate in the plurality of cars in the case where the new hall destination call is responded to.
