Description
The present application is based on Japanese patent application No. 2021-000187 (application No.: 1/4/2021), and is entitled to priority based on this application. This application is incorporated by reference in its entirety.
Technical Field
The present embodiment relates to an elevator control device, an elevator control system, an elevator control method, and a recording medium.
Background
In a conventional elevator control system, a full-load passing function and a full-load changing function for changing a threshold value of a full load are proposed from the viewpoint of eliminating an unnecessary stop and improving the transportation efficiency of an elevator.
Recently, from the viewpoint of a new countermeasure against coronavirus, the above-described function has been used as a function for avoiding the dense and close contact as compared with the improvement of the transport efficiency.
However, if only the threshold value of the full load is changed, even when the demand is low and the responding cars can be distributed, the same car can respond within a range not exceeding the threshold value, and a dense state such as dense state or close state may occur in the car of the elevator.

Detailed Description
Next, the embodiments will be described in detail with reference to the drawings.
Fig. 1 is a diagram illustrating a configuration example of an elevator control system according to an embodiment.
The elevator control system 10 generally includes: a plurality of (3 in the example of fig. 1) elevators 11; an elevator control device 12 that performs group management control of the elevator 11; a plurality of individual control devices 13 for controlling the elevators 11 under the control of the elevator control device 12; and a car call device 14 having at least one of car call buttons 14U and 14D provided in a waiting hall of a general floor (a floor other than a specific floor) of a building in which the elevator 11 is installed.
In the following description, when it is necessary to identify each elevator 11, the elevator is denoted as an elevator 11A (machine a), an elevator 11B (machine B), and an elevator 11C (machine C).
Each car of each elevator 11 is provided with an announcement device 31 for making various announcements and an in-car destination floor indication device 32 provided with destination buttons for designating a destination floor desired by a passenger.
When an elevator hall call (hall call) is made by the car call device 14, the elevator control device (group management device) 12 determines an elevator to respond to a new hall call based on the hall calls already assigned to the elevator 11A, the elevator 11B, and the elevator 11C or the car calls already assigned corresponding to the elevator 11A, the elevator 11B, and the elevator 11C, and outputs an assignment command.
In this case, the elevator control device 12 performs the following control as described below: when the demand is lower than a predetermined value (first predetermined value), the allocation of a new hall call to a midway floor of an allocated hall call registration floor is suppressed, and the allocation of a new hall call to a midway floor of a car call registration floor is suppressed.
The individual control device 13 controls the travel and door opening/closing of the car of any corresponding elevator 11.
At least one car call device 14 is provided at each floor where the elevator 11 stops. The car call device 14 is provided with at least one of an upper call button 14U for calling an elevator toward a floor above the floor on which the car call device 14 is provided, and a lower call button 14D for calling an elevator toward a floor below the floor on which the car call device 14 is provided.
The function of the elevator control device is explained in detail below.
Fig. 2 is a functional block diagram of an elevator control apparatus.
The car call recognition unit 51 of the elevator control device 12 recognizes a car call registration request floor corresponding to a destination floor desired by a passenger, based on an operation state of the in-car destination floor indicator 32 in the elevator 11.
In addition, the car call registration situation management section 52 manages car call registration corresponding to the car call registration floor actually registered and information for specifying the corresponding elevator. Further, the car call registration state management unit 52 functions as an assignment suppression unit that performs control as follows: when the demand is lower than a predetermined value (first predetermined value), the allocation of a new hall call corresponding to a floor midway to the allocated hall call registration floor is suppressed, and the allocation of a new hall call corresponding to a floor midway to the car call registration floor is suppressed.
The hall call recognition unit 53 recognizes a destination direction (upper floor direction or lower floor direction) desired by a passenger in accordance with the floor in accordance with the operation state of the car call device 14 provided at the stop floor of the elevator 11.
The prediction derived car call registration section 54 predicts a car call registration floor of a passenger to be registered in correspondence with an elevator hall call based on the recognition result of the elevator hall call recognition section 53 based on the learning result of the post-assignment call learning section 55, and performs prediction derived car call registration.
The congestion avoidance operation command identifying unit 56 identifies whether or not a congestion avoidance operation command for setting the operation mode of the elevator 11 to the congestion avoidance operation mode is input.
The congestion avoidance operation command is input as input of an external switch provided in the elevator control device 12 for switching on/off of the congestion avoidance operation, setting data in the elevator control device 12, or output of a not-shown timer provided in the elevator control device 12 for controlling on/off of the congestion avoidance operation.
When the congestion avoidance operation command identifying unit 56 identifies that the congestion avoidance operation command has been input, the full load threshold changing unit 57 sets the full load of the car to the side determined to be full (for example, a half of the threshold of the full load at the normal time is set as the threshold at the time of the congestion avoidance operation command input). When the congestion avoidance operation command identifying unit 56 identifies that the congestion avoidance operation command is not input, the full load threshold changing unit 57 sets the full load threshold to the normal full load threshold.
In this case, when the threshold value of the full load at the normal time is changed to the threshold value of the full load at the time of the congestion avoidance operation command input, the full load threshold value changing unit 57 may change the threshold value of the full load for each of the stages by setting the demand stage of the elevator determined by the elevator demand determining unit 63 described later to a plurality of stages. That is, the higher the elevator demand is, the higher the possibility that the inside of the car becomes dense, and therefore the threshold value for the full load can be set to be low.
The car information recognition unit 58 recognizes the actual position and the traveling direction of each car of the elevators 11A to 11C.
In a normal state where the congestion avoidance operation command is not input, the normal-time assigned evaluation value calculation unit 59 calculates and outputs each normal-time assigned evaluation value for each of the cars of the elevators 11A to 11C based on the predicted derived car call registration of the predicted derived car call registration unit 54, the full-load threshold value (in a normal state), and the actual positions and traveling directions of the cars of the elevators 11A to 11C.
The hall call allocation situation management unit 60 manages hall call registration corresponding to the hall call registration floor actually registered and information for identifying the corresponding elevator based on the recognition result of the hall call recognition unit 53.
The hall call allocation situation management unit 60 manages hall call registration corresponding to the hall call registration floor actually registered and information for specifying the corresponding elevator.
The hall call allocation restricted zone determination unit 61 determines a zone (a traveling zone of a car) in which new hall call allocation is restricted, based on the hall call allocation status, the car call registration status, and the derived car call registration status.
The average non-response time measuring unit 62 measures an average response time, which is an average value of non-response times within a predetermined time, as the non-response time, which is a time from the start of registration of an elevator hall call to the response of the elevator hall call (the time when an assignment command corresponding to a car is actually output to the corresponding individual control device 13).
The elevator demand determination unit 63 determines an elevator demand at that time based on the average unresponsive time. That is, the elevator demand is determined to be lower as the average unresponsive time is shorter, and the elevator demand is determined to be higher as the average unresponsive time is longer.
When congestion avoidance of a congestion avoidance operation command is input (when the operation mode is the congestion avoidance operation mode), the congestion avoidance assignment evaluation value calculation unit 64 calculates and outputs a congestion avoidance assignment evaluation value for each of the cars of the elevators 11A to 11C based on the full load threshold, the hall call assignment restriction section, and the elevator demand, and the actual position and traveling direction of each of the cars of the elevators 11A to 11C.
As a result, the hall call assigned car determination unit 65 determines a car to be assigned in accordance with the hall call, based on the respective normal assignment evaluation values calculated for the cars of the elevators 11A to 11C at the normal time.
In the congestion avoidance operation mode, the hall call assigned car determining unit 65 determines a car to be assigned in accordance with a hall call based on the congestion avoidance assignment evaluation values calculated for the cars of the elevators 11A to 11C.
When a car to be assigned in accordance with a hall call is determined, the hall call assigned car determining unit 65 outputs an assignment command corresponding to the car to the corresponding individual control device 13 via the assignment command outputting unit 66.
Next, the outline operation in the congestion avoidance operation mode in the embodiment will be described.
Fig. 3 is a process flow diagram of an embodiment.
First, the congestion avoidance operation command recognition unit 56 of the elevator control device 12 recognizes whether or not the operation mode is the congestion avoidance operation mode, and the elevator control device 12 determines whether or not the current operation mode is the congestion avoidance operation mode (step S11).
If it is determined in step S11 that the current operation mode is not the congestion avoidance operation mode, that is, the normal operation mode (no in step S11), the process ends.
When it is determined at step S11 that the current operation mode is the congestion avoidance operation mode (yes at step S11), the full load threshold changing unit 57 of the elevator control device 12 sets the full load threshold in the decreasing direction (step S12).
Next, the average unresponsive time measuring unit 62 of the elevator control device 12 measures the average unresponsive time (step S13).
Next, the elevator control device 12 determines whether or not the measured average unresponsive time is equal to or less than a predetermined value, that is, whether or not the elevator demand is low, i.e., a so-called idle state (step S14).
When the average non-response time exceeds a certain value in the determination at step S14 (no at step S14), the situation is that the demand for the elevator is high and the elevator is congested, and therefore, the operation in the congestion avoidance operation mode is instead congested in the elevator hall (hall), and the process is terminated to temporarily stop the operation in the congestion avoidance operation mode.
When the average non-response time is equal to or less than the fixed value in the determination of step S14 (yes in step S14), the congestion avoidance operation mode is continued, whereby the dense state of the car can be avoided, and therefore the elevator control device 12 determines whether or not there is an hall call allocation request from any one of the car call devices 14 at that time by the hall call recognition unit 53 (step S15).
When it is determined at step S15 that there is a hall call allocation request from any one of the car call devices 14 at that time (yes at step S15), the elevator control device 12 determines whether there is an actual car call registration by the car call registration status management section 52 (step S16).
If it is determined at step S16 that there is an actual car call registration (yes at step S16), hall call allocation is suppressed for the elevator 11 (any of the elevators 11A to 11C) so that no new hall call allocation is performed for the elevator until the route to the hall call allocation floor (the route from the current car position to the hall call allocation floor) and the actual car call registration floor (step S17).
As a result, it is possible to prevent other passengers from entering the car of the elevator before reaching the hall call allocation floor or before reaching the actual car call registration floor, so that the state of the car is not more dense before the passenger enters the car at the hall call registration floor or before the passenger leaves the car at the actual car call registration floor.
On the other hand, when it is determined at step S16 that there is no actual car call registration (no at step S16), for the elevator 11 (any of the elevators 11A to 11C), the hall call allocation is suppressed so that no new hall call allocation is performed for the elevator during the travel of the route to the hall call allocation floor (the route from the current car position to the hall call allocation floor) and the route to the predicted derived car call registration floor corresponding to the predicted derived car call registration obtained by predicting the car call registration floor of the passenger who is predicted to be registered in association with the hall call, and the process is ended (step S18).
As a result, it is possible to prevent other passengers from entering the car of the elevator before arriving at the hall call allocation floor or before arriving at the predicted derived car call registration floor, and therefore the state of the car is not more dense before the passenger enters the car in the hall call registration floor or before the passenger leaves the car in the predicted derived car call registration floor.
When it is determined at step S15 that an elevator hall call assignment has not been requested from any of the car call devices 14 at that time (no at step S15), the elevator control device 12 determines whether or not there is an actual car call registration by the car call registration status management unit 52 (step S19).
If it is determined at step S19 that there is no actual car call registration (no at step S19), the process ends because the operation in the congestion avoidance operation mode is not effective.
When it is determined at step S19 that there is an actual car call registration (yes at step S19), hall call allocation is suppressed for the elevator 11 (any one of the elevators 11A to 11C) so that no new hall call allocation is performed for the elevator until the actual car call registration floor is reached, and the process ends (step S20).
As a result, it is possible to prevent other passengers from entering the car of the elevator before reaching the actual car call registration floor, and therefore the dense state of the car does not become denser before the passengers get off the elevator at the actual car call registration floor.
As described above, according to the present embodiment, the full-state setting (full-state load threshold) of each car of the elevator is reduced, for example, to half of the normal setting, and the full-state notification to the rated person after the change and the control of the full-state are performed, and in the time zone where the demand of the elevator is low, the assignment suppression of the new hall call to the assigned hall call floor and the assignment suppression of the new hall call to the predicted derived car call registration floor or the actual car call registration floor are performed in accordance with the registration statuses of the hall call and the car call, whereby the assigned cars of the hall call can be distributed, and thus, a denser state can be avoided.
The embodiments of the present invention have been described above, but these embodiments are presented as examples and are not intended to limit the scope of the invention. These embodiments can be implemented in other various manners, and various omissions, substitutions, and changes can be made without departing from the spirit of the invention.
For example, the elevator demand may be divided into several stages (first to nth predetermined values [ n is an integer of 2 or more ]: first predetermined value > second predetermined value > … > nth predetermined value), and the degree of suppression of the new hall call may be changed. In other words, the lower the elevator demand, the higher the suppression degree of the new hall call.
It is also possible to suppress the corresponding new hall call at all times without depending on the need when congestion is avoided.
In addition, instead of suppressing the allocation of new hall calls, allocation may be prohibited.
In addition, the suppression degree of the corresponding new hall call may be changed according to the number of the allocated hall calls for each car.
In addition, the degree of suppression of a new hall call may be changed in consideration of the load in each car. Specifically, the degree of suppression may be increased even when the load is higher.
Further, the call registration function for congestion avoidance may be provided, and the assignment of a new hall call may be restricted only to the registrant who has performed the call registration for congestion avoidance.
In addition, the number of elevators in which congestion avoidance operation is performed may be limited to a part of the number of elevators.
The elevator control device according to the present embodiment includes a control device such as a CPU, a storage device such as a rom (read Only memory) or a RAM, and an external storage device such as an HDD or an SSD, and is configured by hardware using a general computer.
The program executed by the elevator control device according to the present embodiment is provided as a file in an attachable or executable format, which is recorded on a computer-readable recording medium such as a memory card, a USB memory, or a semiconductor memory device such as an SSD (solid state disk), a dvd (digital Versatile disk), or a BD (Blu-ray (registered trademark)).
The program executed by the elevator control device according to the present embodiment may be stored in a computer connected to a network such as the internet and downloaded via the network to provide the program. The program executed by the elevator control device according to the present embodiment may be provided or distributed via a network such as the internet.
The program of the elevator control device according to the present embodiment may be provided by being loaded in advance into a ROM or the like.
These embodiments and modifications are included in the invention described in the claims and the equivalent range thereof, as well as in the scope and gist of the invention.
