When the passenger presses any of the landing call registration buttons, the landing call registration units 70A, 70B, 70C,... Recognize the destination directions desired by the passengers. However, the hall call registration unit 70 may not be provided in each of the cages 30A, 30B, 30C,..., And one or more halls may be provided in each floor. In addition, when the passenger guiding unit 60 is an announcement device, one or more landings for each floor may be provided similarly to this. In these cases, the landing call registration unit 70 and the passenger guiding unit 60 may be directly connected to the elevator group management control device 10 via a communication line, unlike the other configurations described later.

  The passenger detection unit 40, the fullness determination unit 50, the passenger guidance unit 60, and the hall call registration unit 70 are connected to the corresponding operation control device 20 via a communication line. Thus, the passenger detection unit 40, the fullness determination unit 50, the passenger guidance unit 60, and the hall call registration unit 70 can notify the operation control device 20 of information related to various operation statuses of the car 30.

  The operation control device 20 includes a CPU (central processing unit) mutually connected by a bidirectional common bus of a normal format, a ROM (Read Only Memory) pre-stored with a predetermined control program, etc., an operation of the CPU A microcomputer (Random Access Memory) for temporarily storing results, a map RAM prepared in advance, a backup RAM for storing information such as elevator specifications, and a microcomputer having an input / output port device and a drive circuit are provided.

  The elevator group management control device 10 includes a CPU (central processing unit) mutually connected by a bidirectional common bus of a normal type, a ROM (Read Only Memory) storing a predetermined control program and the like in advance, a CPU The microcomputer has a RAM (Random Access Memory) for temporarily storing the calculation results of the above, a backup RAM for storing information such as map data prepared in advance, specifications of the elevator, etc.

  The elevator group management control device 10 performs group management of a plurality of elevators constituting the elevator group management control system 1 as a group by mutually exchanging detection signals, drive signals, control commands and the like with each operation control device 20. Control.

  The elevator group management control device 10 includes an operation management unit 12 and a dispatch operation unit 13 in addition to the communication interface 11. The communication interface 11 receives various information from the passenger detection unit 40, the fullness determination unit 50, the passenger guidance unit 60, and the hall call registration unit 70 via the individual operation control devices 20. Further, the communication interface 11 is connected to the operation management unit 12 and the allocation calculation unit 13 via a communication line, and transmits an instruction from the operation management unit 12 and the allocation calculation unit 13 to each operation control device 20. The operation management unit 12 grasps and manages the operation status of each car 30 based on the various information received by the communication interface 11. The allocation operation unit 13 performs arithmetic processing based on the operation status of each cage 30 determined by the operation management unit 12, and determines which one of the vehicles 30 is to be allocated according to a landing call or the like.

  Next, functions of the passenger detection unit 40 and the person detection unit 41 will be described with reference to FIGS. 2 and 3.

  FIG. 2 is a diagram showing one floor on which the elevator group management control system 1 according to the first embodiment is installed. FIG. 3 is a view for explaining a passenger detection function by the passenger detection unit 40 of the elevator group management control system 1 according to the first embodiment. In FIG.2 and FIG.3, although the structure concerning the cage | basket 30A is demonstrated to an example, the structure concerning another cage | basket 30B, 30C ... has a similar function.

  As shown in FIGS. 2 and 3, the camera 80A is provided, for example, above the cage door 31A in the cage 30A. Thereby, the camera 80A captures the situation within a certain range (the shooting range 81A) of the landing 90 of each floor with the landing door 91A corresponding to the loading / unloading position of the cage door 31A and the loading / unloading position of the cage 30A at the landing 90 open. can do. The video to be captured may be a moving image or a still image captured at regular intervals, and is sequentially transferred to the passenger detection unit 40A.

  The person detection unit 41A of the passenger detection unit 40A analyzes the image of the image transferred from the camera 80A within a fixed period from when the car door 31A and the landing door 91A start door opening to when door closing is completed. , It is detected whether or not there is a person in the imaging range 81A. The predetermined period is, for example, a period from when the car door 31A and the landing door 91A start door opening to when the door closing is completed. In addition, a period from the start of the door closing by the basket door 31A and the landing door 91A to the completion of the door closing may be a certain period. When the video is a still image, the camera 80A is set to perform at least one shooting within such a fixed period. As a method of detecting a person from an image, a general method such as a method of pattern recognition of the connection of each part such as the head and body can be used. When the person detection unit 41A detects a person within the shooting range 81A of the landing 90, the passenger detection unit 40A detects the detected person as a passenger, that is, a person who desires to board the car 30A.

  Here, as shown in FIGS. 2 and 3, it is assumed that there are persons M1 and M2 at the landing 90. The person M1 is within the imaging range 81A of the camera 80A, and the person M2 is outside the imaging range 81A of the camera 80A. At this time, only the person M1 appears in the image of the camera 80A. The person detection unit 41A detects a person based on the video. Therefore, only the person M1 is detected by the person detection unit 41A, and the person M2 is not detected. The passenger detection unit 40A detects only the detected person M1 as a passenger in the landing 90.

  If the passenger detection unit 40 detects a passenger at the landing 90 after the car 30 allocated by the landing call becomes full, the operation control device 20 determines that there is a remaining load. The presence of the remaining cargo means that a person who desires to board the arranged car 30 is left at the landing 90. The operation control device 20 notifies the elevator group management control device 10 of the determination on the presence of the unstacked state.

  The operation management unit 12 of the elevator group management control device 10 acquires the position of each car 30 with reference to the individual operation control devices 20 when notified of the determination of the presence of the remaining stacking. Then, when there is a car 30 waiting on the same floor as the floor where the unstacked state is generated, the allocation operation unit 13 performs arithmetic processing to determine which one of the boxes 30 is to be allocated. Specifically, when there is only one waiting basket 30, the dispatch of the basket 30 is determined. If there are a plurality of cages 30 waiting, the dispatch of the cage 30 closer to the basket 30 that is initially dispatched among the cages 30, that is, the cage 30 that is full is determined. The communication interface 11 notifies the operation control device 20 of the car 30 of which the allocation has been determined.

  According to the notification from the elevator group management control device 10, the operation control apparatus 20 of the car 30 for which allocation has been determined distributes the car 30 waiting without waiting for the start of traveling of the car 30 which is full. Here, in the cage 30 waiting, the cage door 31 and the corresponding landing door 91 are in a closed state. To distribute the waiting cage 30 is to open the cage door 31 and the landing door 91 of the cage 30 so that passengers can board. The operation control device 20 also guides the leftover passenger to the distributed car 30 by the passenger guiding unit 60 corresponding to the distributed car 30. Specifically, the passenger is guided by an announcement by an announcement device, lighting or blinking of a lantern device, a chime sound of a chime device, or the like.

(Example of elevator control process)
Next, elevator control processing in the elevator group management control system 1 will be described with reference to FIG. FIG. 4 is a flowchart showing an example of the procedure of elevator control processing in the elevator group management control system 1.

  As shown in FIG. 4, in step S10, the hall call registration unit 70 registers a hall call on a certain floor. In step S20, the allocation calculation unit 13 of the elevator group management control device 10 performs allocation calculation processing for all cars 30, and determines the car 30 to be allocated to the registration floor of the hall call. Here, for example, it is assumed that the allocation of the car 30B is determined. In this case, the elevator group management control device 10 notifies the operation control device 20B of the decision of the allocation of the car 30B.

  In step S30, the operation control device 20B causes the car 30B to travel to the hall call registration floor, and opens the car door 31B of the car 30B at the hall call registration floor. At this time, the landing door 91B corresponding to this is also opened. Thus, the passengers of the landing 90 board the cage 30B. In step S40, the operation control device 20B closes the basket door 31B. The closing of the cage door 31B is performed, for example, after a predetermined time has elapsed or after the cage 30B has reached the fullness determination load, or in accordance with the door closing operation in the cage 30B of the passenger. At this time, the landing door 91B is also closed. For example, the fullness determination unit 50B performs the fullness determination of the car 30B continuously from step S10 to step S40. When it is determined that the cage 30B is full, for example, the passenger detection unit 40B detects whether there is a passenger at the landing 90 based on the image of the camera 80B from step S30 to step S40.

  In step S51, the operation control device 20B refers to the full occupancy determination unit 50B to acquire information as to whether or not the full occupancy determination has been made. When the fullness determination is made (Yes), the operation control device 20B refers to the passenger detection unit 40B to obtain information on whether or not a person is detected at the landing 90 in step S52. When a person is detected at the landing 90 (Yes), the operation control device 20B determines that the unstacked state has occurred at the landing 90, and notifies the elevator management control device 10 of the determination. That is, step S51 and step S52 correspond to the unstacking determination step. When both step S51 and step S52 are "Yes", the operation control apparatus 20B determines that there is a leftover.

  In step S60, the operation management unit 12 of the elevator group management control device 10 refers to the operation control devices 20 of all the cages 30 except the cage 30B to acquire the positions of the respective cages 30, and the same floor as the stop floor of the cage 30B. It is determined whether or not there is a cage 30 waiting for.

  If there is the waiting basket 30 (Yes), the dispatch computing unit 13 performs a dispatch computation process for the waiting basket 30 in step S70, and determines the basket 30 to be dispatched. Here, when the cage 30 standing by is only the cage 30C, for example, the dispatch operation unit 13 determines the dispatch of the cage 30C. When the cage 30 standing by is, for example, the cages 30A and 30C and the cage 30A is closer to the cage 30B than the cage 30C, the dispatch operation unit 13 determines the dispatch of the cage 30A. Here, for example, it is assumed that the allocation of the basket 30A is determined. In this case, the elevator group management control device 10 notifies the operation control device 20A of the decision of allocation of the car 30A.

  In step S80, the operation control device 20A allocates the car 30A. That is, the car door 31A of the car 30A, which has been waiting on the same floor as the car 30B, is opened. At this time, the landing door 91A corresponding to this is also opened. As a result, the passengers of the landing 90 can enter the cage 30A.

  In step S90, the operation control device 20A guides the leftover passenger to the car 30A by the passenger guiding unit 60A in the vicinity of the car 30A.

  Thus, the elevator control process in the elevator group management control system 1 ends. When one of steps S51, S52, and S60 is "No", the elevator group management control system 1 ends the elevator control process without performing anything.

  After completion of the elevator control processing, the operation control device 20B of the car 30B, which is initially allocated, starts traveling of the car 30B toward the destination floor.

  In the conventional elevator group management control system, even if there is a cargo waiting at the same floor, when there is a cargo remaining at the landing, the cargo passenger who is left behind until the first allocated cargo starts traveling. However, I could not use the waiting basket.

  In the elevator group management control system 1 according to the present embodiment, the car 30 which is waiting without waiting for the start of traveling of the car 30 initially allocated is distributed by the above-described configuration, so that the passenger can It can be used. That is, the elevator group management control system 1 can more efficiently distribute another car 30 to the landing 90 after the cars 30 allocated by the landing call become full.

(Modification)
Next, a modification of the present embodiment will be described. In the elevator group management control system of this modification, even if there is no cage 30 waiting at the stop floor of the fully-packed cage 30B, the elevator group management control described above is that another basket 30 is allocated Different from system 1

  That is, in the elevator group management control system of this modification, when there is no cage 30 waiting at step S60 of FIG. 4 (No), the dispatch operation unit 13 removes all the baskets 30 except the cage 30B initially dispatched. From among the above, determine the car 30 to be allocated to the stop floor of the car 30B. The cages 30 to be allocated are determined, for example, from the operation status of each cage 30, the predicted arrival time of the cage 30B to the stop floor, and the like.

  In the conventional elevator group management control system, in order to receive a new car, it is necessary for a passenger who has been left unlaid to wait for the start of traveling of the fully-loaded car to register a landing call again. The

  In the elevator group management control system of the present modified example, another car 30 is dispatched even if the passenger does not perform the landing call registration again. There is no need to wait for the car 30 to start running. Therefore, according to the elevator group management control system of the present modification, it is possible to provide a more convenient service.

Second Embodiment
This embodiment will be described using FIGS. 5 to 8.

(Example of configuration of elevator group management control system)
FIG. 5 is a diagram showing an entire configuration of an elevator group management control system 2 according to a second embodiment. As shown in FIG. 5, the elevator group management control system 2 includes a passenger detection unit 45 instead of the passenger detection unit 40. The other configuration of the elevator group management control system 2 is the same as that of the elevator group management control system 1. Moreover, although only the structure concerning the cage 30A is shown in FIG. 5, the cages 30B, 30C,... Of the elevator group management control system 2 also have the same arrangement. Hereinafter, only the configuration different from the elevator group management control system 1 will be described taking the configuration of the car 30A as an example.

  The passenger detection unit 45A of the elevator group management control system 2 includes a boarding intention determination unit 42A in addition to the person detection unit 41A. When the person detection unit 41A detects a person, the boarding intention determination unit 42A determines whether the person has the intention to board the car 30A based on the change in the position of the person.

  FIG. 6 is a diagram for explaining a passenger detection function by the passenger detection unit 45 of the elevator group management control system 2 according to the second embodiment. As shown in FIG. 6, it is assumed that the persons M1 and M2 are in the imaging range 81A of the camera 80A. The persons M1 and M2 are both within the imaging range 81A of the camera 80A. The person detection unit 41A detects both of the persons M1 and M2 based on the video transferred from the camera 80A within a predetermined period. Such a fixed period is, for example, a period from when the car door 31A and the landing door 91A start to open until the door closing is completed, as in the above-described embodiment. Alternatively, the predetermined period of time is, for example, the period from when the car door 31A and the landing door 91A start closing until completion. When the video is a still image, the camera 80A is set to shoot at least twice within such a fixed period.

  When the person detection unit 41A detects the persons M1 and M2 at the landing 90, the boarding intention determination unit 42A tracks the persons M1 and M2 using a technique such as optical flow. According to the optical flow, the change in the position of the person is represented by a vector. In the example of FIG. 6, it is assumed that the person M1 indicates the change of the position represented by the vector V1, and the person M2 indicates the change of the position represented by the vector V2. The boarding intention determination unit 42A extracts a component directed to the entrance of the car 30A from the vector V1 of the person M1 and calculates the moving speed Vt1 in the entrance direction of the car 30A. When the moving speed Vt1 is equal to or higher than a predetermined speed, the boarding intention determination unit 42A determines that the person M1 has the boarding intention to the cage 30A. On the other hand, the moving speed Vt2 of the person M2 toward the entrance of the cage 30A is less than or equal to zero, and the boarding intention determination unit 42A determines that the person M2 has no intention to board the car 30A.

  When the person detection unit 41A detects a person and the boarding intention determination unit 42A determines that the person has boarding intention, the passenger detection unit 45A detects such a person as a passenger.

(Example of elevator control process)
FIG. 7 is a flowchart showing an example of the procedure of elevator control processing in the elevator group management control system 2. Below, the elevator control processing in the elevator group management control system 2 is demonstrated using FIG. The elevator group management control system 2 is different from the elevator group management control system 1 according to the above-described embodiment only in that the person detected in the landing 90 determines the presence / absence of the riding intention. Hereinafter, only the configuration different from that of the elevator group management control system 1 will be described by taking the configuration of the car 30B as an example.

  As shown in FIG. 7, when the operation control device 20B acquires information that the fullness determination has been made in step S51 (Yes), and acquires information that a person is detected at the landing 90 in step S52 (Yes) In step S53, the operation control device 20B refers to the boarding intention determination unit 42B and acquires information on the presence or absence of the boarding intention of the person. When it is determined that there is an intention to get into the vehicle (Yes), the operation control device 20B determines that unstacked has occurred at the landing 90, and notifies the elevator group management control device 10 of the determination. In other words, steps S51 to S53 correspond to the step of determining whether or not the elevator group management control system 2 is left. When all the steps S51 to S53 are "Yes", the operation control device 20B determines that there is an unstacked state.

  Thereafter, the elevator control process in the elevator group management control system 2 ends with the same flow as the above-described embodiment. When one of steps S51, S52, S53, and S60 is "No", the elevator group management control system 2 ends the elevator control process without performing anything. However, when step S60 is "No", another cage 30 may be distributed as in the modification of the first embodiment described above.

  In the elevator group management control system 2, with the above configuration, it is possible to more reliably determine the presence or absence of stacking. That is, it is possible to sort out passengers who wish to board the cage 30 from the persons present at the landing 90. Therefore, the elevator group management control system 2 can allocate the more efficient car 30 by minimizing the unnecessary car 30 being allocated after the car 30 allocated by the hall call becomes full. .

(Modification)
FIG. 8 is a flowchart showing an example of the procedure of elevator control processing in the elevator group management control system according to the modification of the second embodiment. Below, the elevator control processing of this modification is demonstrated using FIG. The elevator control process of the modification differs from the above-described elevator group management control system 2 in that the car 30 is allocated regardless of the presence or absence of the fullness determination. Hereinafter, only the configuration different from the elevator group management control system 2 will be described taking the configuration of the car 30B as an example.

  As shown in FIG. 8, when the operation control device 20B acquires the information that the fullness determination has been made in step S51 a (Yes), the process proceeds to step S52 in FIG. 7. When the information that the fullness determination has been made is not obtained in step S51a, that is, when the car 30B is not full (No), the operation control device 20B refers to the person detection unit 41B in step S52a, and the landing 90 Get information on the presence or absence of a person. When a person is detected at the landing 90 (Yes), the operation control device 20B refers to the boarding intention determination unit 42B and acquires information on the presence or absence of the boarding intention of the person in step S53a. When it is determined that there is an intention to get into the vehicle (Yes), the operation control device 20B determines that unstacked has occurred at the landing 90, and notifies the elevator group management control device 10 of the determination. That is, step S52a and step S53a correspond to the unstacking determination step in this modification. When both step S52a and step S53a are "Yes", the operation control apparatus 20B determines that there is a leftover.

  As described above, the full load determination load of the full load determination unit 50B is set to a value slightly lower than the maximum load load. Therefore, when the fullness determination is not made, the cage 30B has room for a few more passengers to reach until the maximum load capacity is reached. Therefore, the elevator group management control device 10 notifies the operation control device 20B of the redistribution of the car 30B.

  In step S80a, the operation control device 20B redistributes the car 30B. That is, the door 31B of the basket 30B is opened. At this time, the landing door 91B corresponding to this is also opened. As a result, the passengers of the landing 90 can enter the cage 30B.

  In step S90a, the operation control device 20B guides the leftover passenger to the cage 30B by the passenger guiding unit 60B in the vicinity of the cage 30B.

  Thus, the elevator control process in the elevator group management control system of the present modification is completed. When one of steps S52a and S53a is "No", the elevator group management control system of this modification ends the elevator control processing without performing anything.

  In the elevator group management control system of the present modification, by the above configuration, it is possible to save time and effort for allocating another car 30 by redistributing the car 30B which is not full. As a result, the basket 30 can be distributed more efficiently.
