[0027] 《First Implementation Method》

[0028] -Elevator structure-

[0029] Figure 1 1 is a system configuration diagram showing a schematic configuration of an elevator according to the first embodiment and the second embodiment. Figure 1 The structure of the elevator 1 involved in the first embodiment is explained with reference to other drawings as needed.

[0030] The elevator 1 shown in the figure has a plurality of (n) elevators 10, lobby equipment 20, and an operation management device 30 for managing the operation of the plurality of elevators 10. These are connected to each other via a network 2. The details of each element constituting the elevator 1 are described in order below. In addition, whenever the present invention is described, the embodiments are generally constructed in a form that is easy to explain, but the structure is not limited to this. For example, although the operation management device 30 and the elevator 10 are divided into different structures, it is also possible to construct the operation management device 30 in the elevator 10. In this case, it is also possible to construct a master / slave structure in the elevator 10, and the master elevator plays the role of the operation management device 30.

[0031] <Elevator No. 10>

[0032] The elevator 10 is installed in a building. Here, the elevator 1 is provided with n elevators 10, namely, elevator 10-1 to elevator 10-n. Each elevator 10 includes a car 10a and a traction machine (not shown) for running the car 10a. The car 10a has a car door (not shown) that can be freely opened and closed.

[0033] Each elevator car 10 is provided with a load detection unit 11, a camera in the car 12, a destination floor registration unit 13, a display unit 14, a speaker 15, and an elevator control unit 16. These are as follows.

[0034] [Load detection unit 11]

[0035] The load detection unit 11 detects a load applied to the car 10 a by passengers and cargo boarding the car 10 a , and transmits the detected load to the car control unit 16 .

[0036] [Camera inside the car 12]

[0037] The camera in the car 12 captures the interior of the car 10a and transmits the captured image information to the operation management device 30 via the car control unit 16 or directly.

[0038] [Destination layer registration unit 13]

[0039] The destination floor registration unit 13 is used by passengers of the car 10a to register destination floors, for example, by button operation. The destination floor information for which the button operation has been performed is transmitted to the operation management device 30 via the elevator control unit 16 or directly.

[0040] [Display unit 14]

[0041] The display unit 14 displays information such as the destination floor of the car 10a based on an instruction from the elevator control unit 16. Such a display unit 14 is one of the notification means for notifying the passengers of the car 10a of the information.

[0042] [Speaker 15]

[0043] The speaker 15 makes a warning announcement of excess boarding or the like to the car 10a based on an instruction from the car control unit 16. Such a speaker 15 is one of the notification means for notifying the passengers of the car 10a of information.

[0044] [Elevator control unit 16]

[0045] The elevator control unit 16 controls the travel of the elevator car 10a driven by the traction machine, the opening and closing of the elevator door provided on the elevator car 10a, the display of the display unit 14, and the notification from the speaker 15 based on the information from the load detection unit 11 and the camera 12 in the elevator car, and further based on the instructions from the operation management device 30. Such an elevator control unit 16 is composed of a computer. The computer is hardware used as a so-called computer, and can have a non-volatile storage unit such as a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), and an HDD (hard disk drive), and further has a network interface. In addition, the structure of the computer is the same in the following.

[0046] The elevator control unit 16 includes a setting and holding unit 16a, a full-occupancy determination unit 16b, an output control unit 16c, and a departure management unit 16d. Among them, the setting and holding unit 16a holds various setting values ​​for controlling the travel of the car 10a of each elevator 10 and the opening and closing of the car door, such as the over-full threshold and the full threshold. These setting values ​​are set as values ​​input from an external device. The full-occupancy determination unit 16b determines the crowded state in the car 10a based on the information held in the setting and holding unit 16a and the information obtained from the load detection unit 11 and the camera 12 in the car. The output control unit 16c controls the notification of information from the display unit 14 and the speaker 15. The departure management unit 16d implements control for driving the car 10a based on the information from the full-occupancy determination unit 16b and the operation management device 30. These functional units execute each function by a program stored in a computer constituting the elevator control unit 16. The functions executed by each functional unit will be described in detail in the elevator control method later.

[0047] <Hallway Equipment 20>

[0048] The hall equipment 20 is equipment installed in each hall, and includes a call registration unit 21, a hall camera 22, a response lamp 23, and a hall notification unit 24. Each of these may be individually arranged in a plurality in each hall, or may be arranged in a single unit. When a plurality of these are arranged, as an example, they are arranged for each hall door corresponding to each elevator 10. Next, the call registration unit 21, the hall camera 22, the response lamp 23, and the hall notification unit 24 are described in order.

[0049] [Call registration unit 21]

[0050] The call registration unit 21 is used for the passenger to input the destination floor, and may be, for example, a keypad, or may be a structure that reads the identification information of the passenger. The destination floor input or read from the call registration unit 21 is sent to the operation management device 30 .

[0051] [Hallway Camera 22]

[0052] The hallway camera 22 captures the hallway. The hallway camera 22 may have a resolution that allows it to count, for example, the number of passengers waiting in the hallway and the increase or decrease in the number of passengers. The hallway camera 22 may be one of the elements constituting a personal authentication system for passengers. The image captured by the hallway camera 22 is processed in a data processing unit (not shown) and then transmitted to each elevator 10, and further transmitted to the operation management device 30.

[0053] [Response light 23]

[0054] The response lamp 23 is a display unit for notifying passengers waiting in the lobby of the elevator 10 that has arrived at the lobby floor, and is arranged corresponding to the lobby door of each elevator 10. Such a response lamp 23 also has a function of notifying the travel direction of the arriving car 10a, for example, by lighting up either of the two directions of upward or downward, the passengers waiting in the lobby are notified of the arrival and travel direction of the car 10a.

[0055] [Hall Information Department 24]

[0056] The hall notification unit 24 notifies various information related to the operation of the elevator car 10 based on instructions from the operation management device 30 described later. The hall notification unit 24 is, for example, a display unit or a speaker, and performs notification by display or sound.

[0057] <Operation Management Device 30>

[0058] The operation management device 30 is used to manage the operation of the plurality of elevator cars 10, and is constituted by a computer. Such an operation management device 30 has a management control unit 31 and a learning unit 32 as functional units. These are as follows.

[0059] [Management control unit 31]

[0060] The management control unit 31 allocates elevators 10 to each lobby floor and formulates the operation route of each elevator 10 based on the information sent from each elevator 10, the information sent from each lobby equipment 20, and the information from the learning unit 32 described below. In addition, the management control unit 31 controls the lighting of the response lamp 23 of each lobby equipment 20 and the notification of the lobby notification unit 24.

[0061] Such a management control unit 31 includes functional units such as an input information processing unit 31a, an elevator allocation unit 31b, a hall output control unit 31c, and a plurality of elevator dispatch control unit 31d. Among them, the input information processing unit 31a controls information from each hall equipment 20 and each elevator 10. The elevator allocation unit 31b controls the registration of calls to each elevator 10 and instructs the registration of calls to each elevator 10. The hall output control unit 31c controls the output from the response lamp 23 and the hall notification unit 24 in each hall equipment 20. The plurality of elevator dispatch control unit 31d controls the concentration of elevator dispatch to a given hall for a given period of time.

[0062] Each of these functional units executes each function by a program stored in a computer constituting the management control unit 31. The function executed by each functional unit will be described in detail in the elevator control method later.

[0063] [Learning Department 32]

[0064] The learning unit 32 selects an operation program based on various information, and instructs the management control unit 31 to perform operation control based on the operation program. Figure 2 This is a diagram for explaining the function of the learning unit 32 of the elevator 1. Figure 2 as well as Figure 1 The learning unit 32, for example, creates utilization status data 41 representing the number of passengers getting on and off per unit time period on each floor as a traffic demand status based on information collected from the lobby cameras on each floor. Furthermore, the learning unit 32 learns the traffic flow (also called human flow) representing the flow of passengers in each elevator 10 based on the operation data of the elevator 1 accumulated in the past, and generates learning results (traffic patterns M1 to M6). The generated traffic patterns M1 to M6 are distinguished and shown on the coordinates 42 with the horizontal axis representing the number of passengers getting on and off downward and the vertical axis representing the number of passengers getting on and off upward. In addition, the learning unit 32 selects the optimal operation program for the traffic pattern at the current time point from the operation programs generated by the intelligent unit (not shown here), and instructs the management control unit 31 to perform operation control based on the operation program.

[0065] - Elevator control method according to first embodiment -

[0066] Next, a description will be given of an elevator control method according to a first embodiment implemented by the elevator 1 as described above. Figure 3 This is a flowchart showing the control performed by the elevator control unit in the control method of the elevator 1 according to the first embodiment, and shows the process of the control performed by the elevator control unit 16 of each elevator 10 when the elevator is overcrowded. Figure 4 This is a flowchart showing the control performed by the operation management device in the control method of the elevator according to the first embodiment, and shows the control process performed in the management control unit 31 of the operation management device 30. Here, the so-called overcrowding refers to a state in which the car 10a is extremely crowded, and it means a state in which the departure of the car 10a needs to be suppressed.

[0067] The following references the previous Figure 1 , in accordance with Figure 3 as well as Figure 4 The control method of the elevator of the first embodiment is described in the order of the flowchart. In addition, these processes are repeated periodically.

[0068] <Control of the elevator control unit 16 ( Figure 3 )>

[0069] First, based on Figure 3 The process, reference Figure 1 The following describes the process of control performed by the elevator control section 16 of each elevator car 10 when the elevator is overcrowded.

[0070] [Step S11]

[0071] In step S11, the departure management unit 16d determines whether there is an instruction for hall call registration from the elevator allocation unit 31b of the management control unit 31. If it is determined that there is a registration (Yes), the car 10a is driven to the floor where the hall call registration is instructed, and the process proceeds to step S12. On the other hand, if it is determined that there is no registration (No), the process ends.

[0072] [Step S12]

[0073] In step S12, when the car 10a registered in step S11 arrives at the floor with the hall call registration indication and it is determined that the car 10a has its door open (yes), the departure management unit 16d proceeds to the next step S13, and ends the processing if the door is not open (no).

[0074] [Step S13]

[0075] In step S13, the full-crowd determination unit 16b determines whether the load value detected by the load detection unit 11 exceeds the overcrowding threshold value. Here, the overcrowding threshold value is a threshold value set for the load value in order to suppress the departure of the car 10a. It is a value previously stored in the setting storage unit 16a, but it may be a value stored in the setting storage unit 16a of each elevator 10 by input from an external device. Under normal circumstances, such an overcrowding threshold value is a value of about 110% of the rated load of each elevator 10.

[0076] In this case, the full occupancy determination unit 16b compares the over-full threshold value held in the setting holding unit 16a with the load value detected by the load detection unit 11 to make the determination, and if it is determined that the over-full threshold value is exceeded (yes), the process proceeds to step S14. On the other hand, if it is determined that the load value detected by the load detection unit 11 is not over-full threshold value (no), the process proceeds to step S17.

[0077] [Step S14]

[0078] In step S14, the full-capacity determination unit 16b turns on an overcrowding signal to be sent to the management control unit 31. Thus, the overcrowding signal starts to be sent to the management control unit 31.

[0079] [Step S15]

[0080] In step S15, the departure management unit 16d maintains the car door in the open state at the floor where the hall call registration is instructed. By this process, control is established for suppressing departure from the floor when overcrowding is detected in the car 10.

[0081] [Step S16]

[0082] In step S16, the output control unit 16c instructs the speaker 15 to announce the guidance of getting off the elevator. Thus, the speaker 15 broadcasts the guidance of getting off the elevator in the overcrowded state. Then, the process returns to step S13, and the process from step S13 to step S16 is repeated until step S13 determines that the load value does not exceed the overcrowded threshold value (no), that is, until the load value in the elevator car 10a decreases to below the overcrowded threshold value due to passengers getting off the elevator car 10a.

[0083] [Step S17]

[0084] On the other hand, step S17 is a step to be performed when it is determined in step S13 that the load value does not exceed the overcrowding threshold value (No). In this step S17, the full-crowding determination unit 16b turns off the overcrowding signal sent to the management control unit 31.

[0085] [Step S18]

[0086] In step S18, the departure management unit 16d closes the door of the car 10a, and then causes the car 10a to travel to the registered destination floor, and then terminates the process.

[0087] <Control of the operation management device 30 ( Figure 4 )>

[0088] Next, based on Figure 4 The process, reference Figure 1 The process of the immediate elevator dispatch control performed in the management control unit 31 of the operation management device 30 will be described.

[0089] [Step S101]

[0090] In step S101, the input information processing unit 31a determines whether there is a surplus in any lobby. Here, for example, the judgment is made based on whether an overcrowding signal is received from elevator No. 1 10-1. When an overcrowding signal is detected, control is implemented to suppress the departure of the elevator car 10a of the elevator (for example, elevator No. 1 10-1), and a broadcast is issued to urge people to get off the elevator. In other words, it can be seen that there must be more than one person left in the lobby. Therefore, the detection of an overcrowding signal is synonymous with the occurrence of surplus. The overcrowding signal is Figure 3 In step S14, the signal is sent from the full-occupancy determination unit 16b of the elevator control unit 16. In addition, the judgment of the remaining load in the hallway can be performed by a detection unit in the hallway such as the hallway camera 22. In step S101, if it is judged that the remaining load occurs (yes), the process proceeds to step S102, and otherwise the process ends.

[0091] [Step S102]

[0092] In step S102, the elevator allocating unit 31b determines whether there is an elevator that can be allocated. At this time, the elevator allocating unit 31b excludes the elevators that cannot be allocated except the elevators with excess loading (here, for example, elevator No. 1 10-1) from the multiple elevators 10. If there is an elevator 10 that can be allocated to the car 10a, it is determined that there is an elevator that can be allocated (yes), and the process proceeds to step S103. On the other hand, if there is no elevator 10 that can be allocated except the elevator No. 1 10-1 with excess loading, the elevator allocating unit 31b determines that there is no elevator that can be allocated (no), and the process proceeds to step S105.

[0093] [Step S103]

[0094] In step S103, the elevator allocating unit 31b immediately allocates the elevator number 10 determined to be allocable to the hallway where the overstocking occurs by adding the elevator number 10. Thus, the additional elevator number 10 can be immediately allocated to the hallway where the overstocking occurs.

[0095] [Step S104]

[0096] In step S104, the hall output control unit 31c sends an instruction to light up in the same direction as the immediately preceding call to the response lamp 23 arranged in the remaining hall corresponding to the additional elevator number 10. Thus, the response lamp 23 of the arrival floor lights up in the same direction as the immediately preceding call.

[0097] [Step S105]

[0098] On the other hand, step S105 is the step to proceed to when it is determined in step S102 that no elevator can be assigned (No). Here, the so-called elevator that cannot be assigned refers to an elevator that cannot be assigned at all, such as an elevator that is in a malfunction, an elevator that cannot respond to a hall call due to maintenance, etc. In addition, regarding the elevator that cannot be assigned temporarily, it is shown that a state in which the elevator 10 cannot be further boarded due to the temporary detection of overcrowding as shown above, and a state in which boarding is prohibited due to special operation and the hall call is not responded. In this step S105, the call registration unit 21 re-registers the hall call indicated just before for the elevator 10-1 that has been left unloaded. Then, the allocation of the re-registered hall call is retained, and the processing is terminated. Therefore, even if the car 10a of the elevator 10-1 that has been left unloaded is in an open state at the floor where the hall call registration is indicated, the re-registered hall call will not be cancelled. Therefore, after the unloaded No. 1 elevator 10-1 leaves the arrival floor, the user does not register the call again in the call registration unit 21 of the hall equipment 20, but when an elevator that can be allocated appears from the temporary unallocated state, the hall call is allocated to the elevator. In addition, when an elevator under maintenance or an elevator in failure becomes a state that can be allocated, the elevator can also be allocated. After the implementation of this step S105, the process proceeds to step S104.

[0099] -Effects of the First Embodiment-

[0100] According to the control method of the first embodiment described above, when it is confirmed that any elevator number 10 is overloaded at the lobby, the elevator allocation unit 31b of the management control unit 31 immediately allocates an additional elevator number to the lobby where the overload occurs. Therefore, the passengers who are overloaded at the arrival floor of the No. 1 elevator 10-1 can take the next arrival elevator with a shorter waiting time. As a result, the elevator 10a can be allocated efficiently to the passengers who cannot get on the elevator in the elevator car 10a and are waiting in the lobby, and congestion in the lobby can be avoided. In addition, even if there is no elevator number that can be allocated at the time when the management control unit 31 confirms that there is overload in the lobby, the hall call just before is automatically re-registered by the call registration unit 21, and the allocation of the elevator number is reserved, so that the passengers waiting in the lobby can save the time of re-registering the hall call.

[0101] <<Second Implementation Method>>

[0102] The second embodiment is a modification of the first embodiment, and is an example of a case where a full-occupancy threshold used in determining a full-occupancy pass is set. Full-occupancy pass means a state where the elevator needs to pass through the floor with a hall call because the elevator car 10a is crowded even if there is a hall call. In the second embodiment, the first embodiment uses Figure 1The programs of the elevator control unit 16 and the management control unit 31 of the elevator 1 described above are different from those of the first embodiment. Therefore, only the control method of the elevator will be described below.

[0103] - Elevator control method according to the second embodiment -

[0104] Figure 5 1 is a flowchart showing the control performed by the elevator control unit 16 in the control method of the elevator 1 according to the second embodiment. Figure 4 The following refers to the previous Figure 1 , in accordance with Figure 5 as well as Figure 4 The control method of the elevator of the second embodiment is described in the order of the flowchart. In addition, these processes are repeated periodically.

[0105] <Control of the elevator control unit 16 ( Figure 5 )>

[0106] First, based on Figure 5 The process, reference Figure 1 The following describes the control process performed by the elevator control section 16 of each elevator 10 when the interior of the elevator car is in a crowded state.

[0107] [Step S21]

[0108] In step S21, the departure management unit 16d determines whether there is an instruction for hall call registration from the elevator allocation unit 31b of the management control unit 31. If it is determined that there is a registration (Yes), the car 10a is driven to the floor where the hall call registration instruction is given and the process proceeds to step S22. On the other hand, if it is determined that there is no registration (No), the process ends.

[0109] [Step S22]

[0110] In step S22, when the car 10a arrives at the floor where the hall call registration instruction is given and it is determined that the car 10a has its door open (yes), the departure management unit 16d proceeds to the next step S13, and ends the processing if the door is not open (no).

[0111] [Step S23]

[0112] In step S23, the full-occupancy determination unit 16b determines whether the density value in the car exceeds the full-occupancy threshold value in order to determine whether the car 10a of the elevator 10 is in a crowded state. Here, the so-called car density value can be any value that indicates the crowded state (crowded state) in the car 10a, such as the load value of the car 10a, the number of passengers, or the ratio of the floor area not exposed. In addition, the so-called full-occupancy threshold value is a value used for judging when a full car passes during normal operation, and is the maximum car density value allowed for the crowded state in the car 10a. Such a full-occupancy threshold value is a value maintained in the setting maintenance unit 16a of each elevator 10 by input from an external device, and is set to, for example, a value of about 50% of the rated load of each elevator 10.

[0113] In addition, when the density value in the car is set to the number of passengers in the car, the fullness determination unit 16b detects the number of passengers in the car 10a based on the image information from the camera 12 in the car, for example, and compares the detected number of passengers with the threshold calculated based on the capacity of each elevator and the fullness threshold maintained in the setting maintenance unit 16a.

[0114] In addition, when the density value in the car is set as the exposed floor area ratio of the car 10a, the full-occupancy determination unit 16b detects the unexposed floor area occupied in the floor area of ​​the car 10a based on, for example, the value obtained by binarizing the image information from the camera 12 in the car, or based on the distance image information from the 3D camera used as the camera 12 in the car. For example, when there is no user inside the car 10a and only the floor surface is detected, the unexposed floor area becomes 0%. In addition, when the floor area becomes completely filled, it becomes 100%. In addition, the detected unexposed floor area is compared with the full-occupancy threshold value maintained in the setting maintenance unit 16a.

[0115] The full occupancy determination unit 16b proceeds to step S24 when it is determined that the density value in the car exceeds the full occupancy threshold and the car is dense (yes); and proceeds to step S26 when it is determined that the density value in the car does not exceed the full occupancy threshold and the car is not dense (no).

[0116] [Step S24]

[0117] In step S24, the full occupancy determination unit 16b sends a full occupancy signal to the management control unit 31 to notify that the density value in the car exceeds the full occupancy threshold.

[0118] [Step S25]

[0119] In step S25, the output control unit 16c instructs the speaker 15 to notify that the car is full and crowded. As a result, the speaker 15 makes an announcement notifying that the car 10a is crowded.

[0120] [Step S26]

[0121] In step S26, the departure management unit 16d opens the door of the car 10a, and then causes the car 10a to travel to the registered destination floor, and then terminates the process.

[0122] <Control of the operation management device 30 ( Figure 4 )>

[0123] Next, based on Figure 4 The process, reference Figure 1 The following will describe the control process when the car is in a crowded state, which is performed in the management control unit 31 of the operation management device 30. Here, the method of determining the occurrence of overcrowding in the hall in step S101 is different from that in the first embodiment. Therefore, only step S101 will be described.

[0124] [Step S101]

[0125] In step S101, the input information processing unit 31a determines whether there is any overload in any lobby. Here, for example, after receiving a full signal from elevator 10-1, the judgment is made by detecting a decrease in the load value in the elevator car of elevator 10-1 by a certain value or more. It is assumed that after detecting a full state, when a broadcast is broadcasted indicating that it is a dense state, the user gets off the elevator due to the dense state based on the psychological state. Therefore, the overload is detected by the load change after the dense state is broadcasted. The full signal is Figure 5 The load value in the car is obtained from the load detection unit 11 of the No. 1 elevator 10-1. In step S101, the input information processing unit 31a proceeds to step S102 when it is determined that there is overloading (yes), and otherwise the processing is terminated.

[0126] -Effects of the Second Embodiment-

[0127] According to the control method of the second embodiment described above, when the load value in the car 10a of the elevator 10 that has sent a full signal decreases and a passenger is detected to get off the car 10a, the elevator allocation unit 31b of the management control unit 31 immediately allocates an additional elevator to the arrival floor of the elevator 10 that has sent a full signal. Therefore, even for passengers who get off the elevator voluntarily because the car is full while boarding the car at the arrival floor of the elevator 10-1, the car 10a can be allocated efficiently, and congestion in the lobby can be avoided.

[0128] 《Third Implementation Method》

[0129] -Elevator structure-

[0130] Figure 6 This is a system configuration diagram showing a schematic configuration of an elevator 1' according to the third embodiment and the fourth embodiment. The elevator 1' according to the third embodiment shown in the figure is configured to change the full threshold used in determining whether a passenger passes full during normal operation to a value different from a reference value, for example, for the purpose of ensuring social distance between passengers.

[0131] Such, Figure 6 The system structure of the elevator 1' of the third embodiment shown in FIG. Figure 1 The system configuration of the elevator 1 of the first embodiment and the second embodiment shown in the figure is different in the configuration of the multiple elevator dispatching control unit 31d' of the management control unit 31' of the operation management device 30'. Figure 1 The other structures of the elevator 1 of the first embodiment and the second embodiment shown are the same. Therefore, the structure of the multiple elevator dispatching control unit 31d' will be described here.

[0132] <Operation Management Device 30'>

[0133] [Management Control Unit 31']

[0134] The multiple elevator allocation control unit 31d' of the management control unit 31' includes a threshold value correction unit d1 and a multiple elevator allocation control determination unit d2. Figure 6 The predicted number of passengers correction unit d3 in the embodiment is a structure of the following fourth embodiment, and therefore the description here is omitted.

[0135] Among them, the threshold correction unit d1 is a part that corrects each threshold used in the multiple elevator allocation control. In addition, the multiple elevator allocation control determination unit d2 is a part that determines the implementation of the multiple elevator allocation control and calculates the number of elevators to be allocated. The details of the control implemented by these threshold correction units d1 and multiple elevator allocation control determination units d2 will be described in detail in the elevator control method later.

[0136] - Elevator control method according to the third embodiment -

[0137] Next, the elevator control method of the third embodiment implemented by the elevator 1' as described above is described. The elevator control method of the third embodiment is a control method implemented in a structure that can change the full threshold used in the judgment of whether the car is in a crowded state in the elevator control method of the second embodiment. First, the control of the elevator number by the elevator control unit 16 is described below, and then the various controls performed by the operation management device 30' are described.

[0138] <Control of the elevator car 10 by the car control unit 16 ( Figure 7 )>

[0139] Figure 7 1 is a flowchart showing the control performed by the elevator control unit in the elevator control method according to the third embodiment. Figure 7 For the order of the flowchart, refer to the previous Figure 6 The control of the elevator car 10 in the elevator control method according to the third embodiment will be described. In addition, this flow is repeated periodically.

[0140] [Step S31]

[0141] In step S31, the departure management unit 16d determines whether there is an instruction for hall call registration from the elevator allocation unit 31b of the management control unit 31'. If it is determined that there is a registration (Yes), the car 10a is driven to the floor where the hall call registration is indicated, and the process proceeds to step S32. On the other hand, if it is determined that there is no registration (No), the process ends.

[0142] [Step S32]

[0143] In step S32, when the car 10a arrives at the floor with the hall call registration instruction and determines that the car 10a has its door open (yes), the departure management unit 16d proceeds to the next step S33, and ends the processing if the door is not open (no).

[0144] [Step S33]

[0145] In step S33, the full occupancy determination unit 16b determines whether the cage 10a of the elevator 10 is in a crowded state by determining whether the cage density value exceeds the full occupancy threshold. Figure 5 ), so the description here is omitted.

[0146] The full threshold is a reference full threshold that is preset as a value for a full-pass in normal operation, or a full threshold that is rewritten to a value different from the preset reference value. It is assumed that the full threshold is not simply rewritten, but is set to a value lower than the reference value to detect a crowded state in the car. In this case, the setting holding unit 16a holds the rewriting information when the reference full threshold is rewritten.

[0147] The full occupancy determination unit 16b refers to the information held in the setting holding unit 16a, and proceeds to step S34 if it is determined that the density value in the car exceeds the full occupancy threshold (yes), and proceeds to step S36 if it is determined that it does not exceed the full occupancy threshold (no).

[0148] [Step S34]

[0149] In step S34, the full-occupancy determination unit 16b determines whether the full-occupancy threshold used in the determination in step S33 has been revised. If the full-occupancy threshold stored in the setting storage unit 16a has been rewritten, the full-occupancy determination unit 16b determines that it has been rewritten (Yes), and proceeds to step S35. On the other hand, if the full-occupancy threshold stored in the setting storage unit 16a has not been rewritten, the full-occupancy determination unit 16b determines that it has not been rewritten (Yes), and proceeds to step S36.

[0150] [Step S35]

[0151] In step S35, the full determination unit 16b sends a full signal with rewritten information to the management control unit 31'. Here, the full signal with rewritten information is a full signal for notifying that the density value in the car exceeds the full threshold and information indicating that the full threshold has been rewritten.

[0152] [Step S36]

[0153] In step S36, the departure management unit 16d closes the door of the car 10a, and then causes the car 10a to travel to the registered destination floor, and then terminates the process.

[0154] <Control performed by the operation management device 30' ( Figure 8 )>

[0155] Figure 8 1 is a flowchart showing the control performed by the operation management device in the elevator control method according to the third embodiment. Figure 8 For the order of the flowchart, refer to the previous Figure 7 The control method performed by the operation management device in the elevator control method of the third embodiment will be described. In addition, these processes are repeated periodically.

[0156] [Step S301]

[0157] In step S301, the input information processing unit 31a determines whether a full signal with rewriting information is received from the elevator 10. Here, it is assumed that a full signal with rewriting information is received from the elevator 10-1. Figure 7 In step S35, the signal is sent from the full-occupancy determination unit 16b of the elevator control unit 16. In step S301, when the input information processing unit 31a determines that a full-occupancy signal with rewriting information is received (yes), the process proceeds to step S302, and otherwise the process ends.

[0158] [Step S302]

[0159] In step S302, the threshold correction unit d1 of the multiple elevator dispatching control unit 31d' calculates the current full occupancy threshold value as the full occupancy threshold value that is the basis for rewriting the full occupancy threshold value set for the elevator 10-1 based on the load value in the car sent from the elevator 10-1. In addition, in the case where the management control unit 31' can directly obtain the value of the rewritten full occupancy threshold value from the elevator control unit 16 of the elevator 10, this step S302 can also be omitted.

[0160] [Step S303]

[0161] In step S303, the threshold value correction unit d1 of the multiple elevator allocation control unit 31d' corrects each threshold value used in the multiple elevator allocation control based on the current full-occupancy threshold value calculated in step S302. Here, for example, the threshold value correction unit d1 sets [current full-occupancy threshold value] / [full-occupancy threshold value before correction (reference value)] as a coefficient, and corrects each threshold value by multiplying the coefficient by each threshold value before rewriting.

[0162] [Step S304]

[0163] In step S304, the multi-elevator dispatch control determination unit d2 of the multi-elevator dispatch control unit 31d' calculates the predicted number of passengers used in the multi-elevator dispatch control of each lobby. Here, the so-called predicted number of passengers is a predicted value of the number of passengers who take the elevator to the elevator car 10a traveling from each floor to each direction in each time period of a given unit. Here, for example, the predicted number of passengers prepared by the learning unit 32 based on the operation data of the elevator 1 accumulated in the past is used.

[0164] [Step S305]

[0165] In step S305, the multiple elevator dispatching control determination unit d2 of the multiple elevator dispatching control unit 31d' determines whether any hall floor satisfies the implementation conditions of the multiple elevator dispatching control. For example, the determination is made by whether the predicted number of passengers on the floor exceeds the modified threshold value. Here, the modified threshold value is calculated in step S303, and the predicted number of passengers is calculated in step S304. The objects for comparison may be the number of passengers remaining on the floor, the number of passengers at the last departure of the floor, etc. Alternatively, the determination may be made based on, for example, whether a new hall call in the same direction (the direction) is generated on the floor during the period from the departure of the No. 1 elevator 10-1 from the floor to the lapse of a given time (e.g., 5 seconds). Alternatively, the determination may be made based on a combination of these multiple conditions. When it is determined that the implementation conditions of the multiple elevator dispatching control are satisfied (yes), the multiple elevator dispatching control determination unit d2 proceeds to step S306, and otherwise the processing is terminated.

[0166] [Step S306]

[0167] In step S306, the multiple elevators allocation control determination unit d2 of the multiple elevators allocation control unit 31d' sets the direction of the floor determined in step S305 to satisfy the multiple elevators allocation control execution condition as the target of the multiple elevators allocation control.

[0168] [Step S307]

[0169] In step S307, the multiple elevator dispatching control determination unit d2 of the multiple elevator dispatching control unit 31d' performs multiple elevator dispatching control on the lobby floor determined as the target of multiple elevator dispatching control in step 306. For example, the multiple elevator dispatching control determination unit d2 of the multiple elevator dispatching control unit 31d' always dispatches a certain number of elevators 10 to the floor. Here, regarding the number of elevators to be dispatched, the number of elevators 10 to be dispatched to the lobby floor may be determined based on the relationship between the predicted number of passengers on the floor and the threshold. The threshold is calculated in step S303, and the predicted number of passengers is calculated in step S304.

[0170] [Step S308]

[0171] In step S308, the elevator dispatching control determination unit d2 of the elevator dispatching control unit 31d' determines whether the lobby floor set as the target of the elevator dispatching control in step S306 satisfies the termination condition of the elevator dispatching control. For example, it determines whether there is an elevator on the floor that is in the door-closed standby state. If the elevator dispatching control determination unit d2 determines that the termination condition of the elevator dispatching control is satisfied (yes), it proceeds to step S309, otherwise it returns to step S307.

[0172] [Step S309]

[0173] In step S309, the multiple elevator dispatching control determination unit d2 of the multiple elevator dispatching control unit 31d' cancels the setting of the multiple elevator dispatching control for the hall floor set in step S306, and ends the processing.

[0174] -Effects of the Third Embodiment-

[0175] According to the third embodiment described above, even if the full threshold for judging the crowded state in the car 10a is changed, the threshold used in the multiple elevator allocation control can be corrected in the multiple elevator allocation control unit 31d, and the implementation of the multiple elevator allocation control can be judged according to the rewritten full threshold, and the required number of elevators can be allocated to the target floor without excess or deficiency. Thus, by changing the full threshold, the social distance between passengers in the car 10a can be maintained in accordance with the social order, and the multiple elevator allocation control that can also eliminate the crowded state in the lobby can be implemented.

[0176] 《Fourth Implementation Method》

[0177] The fourth embodiment is a variation of the third embodiment, and is another structural example in which the full threshold used for judging full-passenger passing during normal operation is changed to a value different from a reference value for the purpose of ensuring social distance between passengers, for example.

[0178] like Figure 6 As shown in FIG. 1 , the elevator 1' of the fourth embodiment is different from the multiple elevator dispatching control unit 31d' in the structure of the third embodiment in that a predicted number of passengers correction unit d3 is further provided. The structure of the predicted number of passengers correction unit d3 will be described in detail in the elevator control method later. In addition, the control process performed by each unit of the multiple elevator dispatching control unit 31d' is different from that of the third embodiment. Therefore, only the elevator control method will be described below.

[0179] - Elevator control method according to fourth embodiment -

[0180] The control method of the elevator of the fourth embodiment is a modified example of the control method of the elevator of the third embodiment, and the control method of the elevator of the elevator control unit 16 and the use Figure 7 The control method in the third embodiment described is the same. Therefore, the description of the control of the elevator car by the car control unit 16 is omitted here, and only the various controls by the operation management device 30' are described.

[0181] <Control of Operation Management Device 30'>

[0182] In the fourth embodiment, the operation management device 30 implements the following steps in order: (1) multiple elevator dispatching control with correction of the predicted number of passengers, and (2) correction of the predicted number of passengers after the multiple elevator dispatching control is implemented. These steps will be described in order below.

[0183] (1) Multiple elevator dispatch control with correction of predicted passenger numbers

[0184] based on Figure 8 The process of multiple elevator dispatching control implemented by the operation management device in the elevator control method involved in the fourth embodiment is explained by the flow of FIG. Here, the calculation method of the predicted number of passengers in step S304 is different from that in the third embodiment. Therefore, regarding step S304, the control flow is subdivided into Fig. 9 Provide explanation. Fig.10 This is a diagram for explaining correction of the predicted number of passengers according to the fourth embodiment.

[0185] In the following, Figure 8 The control method of step S304 in the embodiment is further subdivided into Fig. 9 For the order of the flowchart, refer to the previous Figure 6 as well as Fig.10 , to illustrate the correction of the predicted number of passengers for the multiple elevator dispatching control implemented by the operation management device. Fig. 9 The process is repeated periodically.

[0186] [Step S401]

[0187] In step S401, the predicted passenger number correction unit d3 of the multiple elevator dispatching control unit 31d' calculates the number of passengers that can be transported per unit time period [Na] (reference Fig.10 (A)). In this case, the predicted passenger number correction unit d3 calculates the stop probability through traffic calculation, for example, and calculates a week based on the calculated stop probability, travel distance, travel time and [capacity] × [occupancy rate], and converts the number of vehicles to calculate the number of people that can be transported per unit time period [Na]. In addition, the predicted passenger number correction unit d3 can also calculate the number of people that can be transported [Na] based on the log of the number of departures on each floor by [number of departures] × [capacity] × [occupancy rate]. Furthermore, the predicted passenger number correction unit d3 can also calculate the number of departures based on the actual travel time of the car 10a, the learning status of the hall call and the car call, and calculate the number of people that can be transported [Na].

[0188] [Step S402]

[0189] In step S402, the predicted number of passengers correction unit d3 of the multiple elevator dispatch control unit 31d' performs processing to set the time period [t] to the current time period [t0] ([t] = [t0]) ( Fig.10 (A)).

[0190] [Step S403]

[0191] In step S403, the predicted passenger number correction unit d3 of the multiple elevator dispatch control unit 31d' determines whether the predicted passenger number [Nrt] of the time period [t] prepared by the learning unit 32 exceeds the transportable passenger number [Na] calculated in step S403 (reference number [Na]) in the time period [t] (first, the time period [t0]). Fig.10 The predicted number of passengers correction unit d3 proceeds to step S404 when it is determined that the number of passengers exceeds (Yes), and proceeds to step S406 when it is determined that the number of passengers does not exceed (No).

[0192] [Step S404]

[0193] In step S404, the predicted passenger number correction unit d3 of the multiple elevator dispatching control unit 31d' makes corrections so that the predicted passenger number [Nrt] in the time period [t] (first, the time period [t0]) does not exceed the number of passengers that can be transported [Na]. For example, the predicted passenger number [Nrt] in the time period [t] (first, the time period [t0]) is corrected to Fig.10 (B)). Then, the predicted number of passengers in the next time period [t+1] is corrected to [Nrt+1] = [Nrt+1] + [Nrt] - [Na] (reference Fig.10 (B)).

[0194] [Step S405]

[0195] In step S405, the predicted passenger number correction unit d3 of the multiple elevator dispatch control unit 31d' performs processing to set the time period [t] to the next time period [t+1] ([t]=[t+1]) (refer to Fig.10 After that, the predicted number of passengers correction unit d3 returns to step S403 until it is determined in step S403 that the predicted number of passengers [Nrt] for the time period [t] does not exceed the number of passengers that can be transported [Na] calculated in step S401 (no) (reference Fig.10 (D)), repeat steps S404 to S405.

[0196] [Step S406]

[0197] Step S406 is the step to be performed when it is determined in step S405 that the predicted number of passengers [Nrt] for the time period [t] does not exceed the number of passengers that can be transported [Na] (no). In this step S406, the hall output control unit 31c instructs the hall notification unit 24 to notify the time period [t]. Here, the time period [t] to be notified is the time period when all passengers heading in the hall to the direction have completed their boarding in the car 10a. Fig.10 In the example shown, it is the time period [t0+2]. The notification here lasts for a certain period. In addition, the time period [t] here can also be used as the end condition of the multiple elevator deployment control in step S308. After this step S406, the processing is terminated.

[0198] [(1) Effect of multiple elevator dispatch control accompanied by correction of predicted number of passengers]

[0199] As described above, when the full threshold is rewritten, by correcting the predicted number of passengers [Nrt] used in the multiple elevator dispatch control based on the rewritten full threshold, the multiple elevator dispatch control can be implemented according to the rewritten full threshold. In addition, by correcting the predicted number of passengers, when the vehicle is operated at the reference full threshold, even in the time period when the passengers cannot be predicted, the multiple elevator dispatch control can be implemented taking into account the passengers that will be generated when the vehicle is operated at the rewritten full threshold. Furthermore, since the time period when all the passengers in the lobby complete their boarding in the car can be predicted, the crowded state in the lobby can be eliminated by performing the multiple elevator dispatch control until the time period has passed. By guiding the time period in the lobby notification unit, the user arriving at the lobby can be provided with judgment materials when selecting the means of movement in the building.

[0200] (2) Correction of the predicted number of passengers after the implementation of multiple elevator dispatching control

[0201] Fig.11 This is a flowchart showing the correction of the predicted number of passengers after the multiple elevator deployment control is implemented by the operation management device in the elevator control method involved in the fourth embodiment. Fig.12 This is a diagram for explaining the correction of the predicted number of passengers after the multiple elevator dispatching control implemented by the operation management device of the fourth embodiment. The predicted number of passengers to be corrected here is calculated using Fig. 9 as well as Fig.10 The predicted number of passengers [Nrt] corrected for the determination of the dispatching control of multiple elevators is described.

[0202] The following, in accordance with Fig.11 For the order of the flowchart, refer to the previous Figure 6 as well as Fig.12 , to illustrate the correction of the predicted number of passengers for the multiple elevator dispatching control implemented by the operation management device. Fig.11 The process is repeated periodically.

[0203] [Step S501]

[0204] In step S501, the predicted passenger number correction unit d3 of the multiple elevator dispatching control unit 31d' determines whether hall calls have been continuously generated since the time period [t0]. At this time, if hall calls for each floor to each direction have been continuously generated since the time period [t0] and after the next time period [t0+1], the predicted passenger number correction unit d3 determines that hall calls have been continuously generated (yes), and proceeds to step S502. Otherwise, the processing ends.

[0205] [Step S502]

[0206] In step S502, the predicted passenger number correction unit d3 of the multiple elevator dispatching control unit 31d' determines whether multiple elevator dispatching control has been performed in the time period [t0]. If it is determined to be performed (yes), the process proceeds to step S503. Otherwise, the process ends.

[0207] [Step S503]

[0208] In step S503, the predicted passenger number correction unit d3 of the multiple elevator dispatch control unit 31d' sets the time period when the hall call continues to end (here, the time period [t0+2]) as the time period [t1] (reference Fig.12 (A)).

[0209] [Step S504]

[0210] In step S504, the predicted passenger number correction unit d3 of the multiple elevator dispatch control unit 31d' sets the predicted passenger number [Nrt] of the time period [t0] to the total value of the predicted passenger number [Nrt] from the time period [t0] to [t1] (reference Fig.12 (B)).

[0211] [Step S505]

[0212] In step S505, the predicted number of passengers correcting unit d3 of the multiple elevator dispatching control unit 31d' sets the predicted number of passengers [Nrt] of each time period [t0+1] to [t1] to zero (refer to Fig.12 (C)).

[0213] [Step S506]

[0214] In step S506, the predicted number of passengers correction unit d3 of the multiple elevator dispatch control unit 31d' performs processing to set the time period [t0] to [t] ([t] = [t0]) (refer to Fig.12 (C)).

[0215] [Step S507]

[0216] In step S507, the predicted passenger number correction unit d3 of the multiple elevator dispatching control unit 31d' determines whether the predicted passenger number [Nrt] of the time period [t] exceeds the number of passengers that can be transported [Nas] under the reference full occupancy threshold (reference Fig.12 (C)). Here, the so-called reference full threshold is set to the unwritten full threshold. The predicted number of passengers correction unit d3 uses the maximum value of the full thresholds calculated in the past, or the value calculated backwards from the current full threshold, as the reference full threshold. The current full threshold is Figure 8If the predicted number of passengers [Nrt] exceeds the transportable number of people [Nas] at the reference full occupancy threshold (Yes), the predicted number of passengers correction unit d3 proceeds to step S508, and if it does not exceed (No), the process ends.

[0217] [Step S508]

[0218] In step S508, the predicted passenger number correction unit d3 of the multiple elevator dispatching control unit 31d' performs correction so that the predicted passenger number [Nrt] in the time period [t] (first, the time period [t0]) does not exceed the number of passengers that can be transported [Nas] under the reference full occupancy threshold (reference Fig.12 (D)). For example, the predicted number of passengers [Nrt] in time period [t] (first time period [t0]) is corrected to the number of passengers that can be transported [Nas] under the benchmark full capacity threshold. Then, the predicted number of passengers [Nrt+1] in the time period [t+1] following time period [t] is corrected to [Nrt+1] = [Nrt] - [Nas] (reference Fig.12 (D) and Fig.12 [Nrt] is the value before correction in step S508 and is the value added in step S504.

[0219] [Step S509]

[0220] In step S509, the predicted passenger number correction unit d3 of the multiple elevator dispatch control unit 31d' performs processing to set the time period [t] to the next time period [t+1] ([t]=[t+1]) (refer to Fig.12 (E)).

[0221] [Step S510]

[0222] In step S510, the predicted passenger number correction unit d3 of the multiple elevator dispatching control unit 31d' determines whether the time period [t] is less than the time period [t1]. If it is determined to be less than the time period [t1] (Yes), the process returns to step S507, and then repeats the steps after step S507. On the other hand, if it is determined that the time period [t] is not less than the time period [t1] (No), the predicted passenger number correction unit d3 ends the process.

[0223] [(2) Effect of Correction of Predicted Passenger Number after Implementation of Multiple Elevator Dispatching Control]

[0224] According to the above, the predicted number of passengers correction unit d3 can make the predicted number of passengers [Nrt] close to the value before correction prepared by the learning unit 32 by re-correcting the predicted number of passengers [Nrt] corrected for implementing the multiple elevator dispatching control in accordance with the rewritten full threshold value based on the reference full threshold value before rewriting. Therefore, even if the rewriting of the full threshold value is cancelled, the multiple elevator dispatching control can be performed in accordance with the reference full threshold value.

[0225] In addition, the present invention is not limited to the above-mentioned embodiments and variations, and further includes various variations. For example, the above-mentioned embodiments are described in detail in order to explain the present invention in an easy-to-understand manner, but are not necessarily limited to all the structures described. In addition, a part of the structure of a certain embodiment can be replaced with the structure of other embodiments, and the structure of other embodiments can be added to the structure of a certain embodiment. In addition, with respect to a part of the structure of each embodiment, other structures can be added, deleted, or replaced. For example, the setting and release of the multiple elevator dispatching control described in the third and fourth embodiments can also be other methods. For example, in the case where the number of people in the lobby can be detected by the lobby camera 22, the detected number of people can also be set to the number of people remaining, and the setting and release of the multiple elevator dispatching control can be implemented according to the number of people.

2. The elevator according to claim 1, characterized in that The operation management device determines that overloading has occurred when it is determined that any one of the elevator cars is in a full state.

3. The elevator according to claim 1, characterized in that: The operation management device determines that overloading has occurred when the load value of the car decreases after determining that any one of the elevator cars is in a full state.

4. The elevator according to claim 2 or 3, characterized in that: The full state is a state in which it is determined that the density value in the car exceeds an arbitrary threshold value.

5. The elevator according to claim 4, characterized in that: The cage density value is the number of people riding in the elevator, and is a value when it is determined that the capacity of the elevator exceeds an arbitrary threshold value.

6. The elevator according to claim 4, characterized in that: The above-mentioned car in-car density value is an exposed floor area ratio, and is a value when it is determined that the non-exposed floor area exceeds an arbitrary threshold value.

7. The elevator according to claim 2 or 3, characterized in that: Each of the elevator car numbers is provided with a notification device for notifying passengers in the car of information. The notification device notifies the full state when the operation management device determines that the car is full.

8. The elevator according to claim 1, characterized in that The operation management device determines the remaining capacity by detecting passengers in the lobby.

9. The elevator according to claim 1, characterized in that: When the operation management device determines that there is no elevator number that can be allocated during the immediate elevator allocation, it re-registers the hall call to the arrival floor of the car determined to be loaded, and reserves the allocation of the re-registered hall call.

10. A method for controlling an elevator, the elevator comprising: a plurality of elevator lots having cars and an elevator control unit for controlling the operation of the cars; and an operation management device for managing the operation of the plurality of elevators, The elevator control method is characterized in that: When the operation management device determines that any of the elevator numbers has caused a surplus, if there is an allocated elevator number that can be used for elevator allocation other than the elevator number that caused the surplus, the car of the added elevator number will be immediately allocated to the arrival floor of the car. When there is no allocated elevator number that can be used for elevator allocation other than the elevator number that caused the surplus, even if the car of the elevator number that caused the surplus is in an open door state at the arrival floor, the hall call indicated just before is re-registered, and the allocation of the re-registered hall call is retained until a car that can be allocated is generated.
