Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an elevator group management system and method.
[0002]
[Prior art]
In a conventional elevator group management system, when a passenger using an elevator presses a button in an elevator hall to generate a hall call, a car allocation request is made to the group management unit. The group management unit allocates a car to the passenger and performs a dispatch service. After getting on the car, the passenger calls the car and designates the destination floor. In response, the group management unit moves the basket to the passenger's destination floor to provide a transport service.
[0003]
Such a conventional elevator group management system can detect the occurrence of the passenger for the first time when the passenger presses the hall call button in the elevator hall to generate the hall call, and can start allocation of the car to the car. That is, the passenger must make a hall call, and the group management side cannot know the destination floor of the passenger unless the hall call occurs.
[0004]
When a hall call occurs, the group management unit predicts the floor at which the passenger who has made the hall call will drop off, and assigns the most suitable car for dispatch according to the operation status of the elevator.
[0005]
Then, when the assigned car arrives at the floor where the passenger who made the hall call arrives, and the passenger gets on the car and makes the car call, the group management section knows the destination floor of the passenger who made the hall call, and Is determined and the passenger is transported to the destination floor. In this way, the elevator group management system carries the passengers generated in the building.
[0006]
For example, when a large number of passengers are generated on a lobby floor or the like at the time of going to work, the passengers feel that it is inefficient and feel an operation burden because it is necessary to make a hall call at each lobby floor. On the other hand, the group management side cannot know the occurrence of passengers unless a hall call occurs, and until then, of course, cannot know the destination floor of the passengers.
[0007]
As far as the passenger's destination floor is not known, the group management has to rely on prediction to identify the passenger's drop-off floor. For this reason, when the prediction is largely out of order, a complaint may be caused due to an increase in waiting time or service time. There is a limit to the technology for predicting the floor at which passengers get off, and it is said that it is difficult to operate elevators with optimal car dispatch.
[0008]
Due to these factors, it cannot be said that a comfortable system is provided for both the passengers who receive the service and the group management side that controls the operation. Therefore, there is a need for an elevator group management system that reduces the burden on passengers due to hall calls and that does not rely on getting off floor prediction.
[0009]
As another conventional example of the elevator group management system, the number of times of operating the landing destination floor buttons is calculated for each landing destination floor button in order to suppress the variation of the congestion degree of each elevator and improve the operation efficiency of the elevator. A button operation counting unit, a destination button light of a landing destination floor button that blinks the number of times based on the calculation result of the destination floor-specific button operation counting unit, and each elevator based on a calculation result of the destination floor-specific button operation counting unit, 2. Description of the Related Art There is known an elevator group management system including an allocating unit for allocating a floor to be serviced and a service floor guide display for displaying a floor to be serviced by each elevator based on an allocation result by the allocating unit (Patent Document 1 below). reference.). In this conventional example, the number of times a passenger makes a destination call is detected, and the traffic volume between floors is acquired. Based on this, a car assignment process is performed. Further, the contents shown on the service floor guidance display board are the service available floors of the car.
[0010]
There is also known an elevator group management control device that controls the operation of elevators at equal time intervals to reduce waiting time, prevent a decrease in transportation efficiency on a crowded floor, and improve service performance (see the following patent). Reference 2). This device sets an operation plan for each elevator, determines a zone to prioritize, suppresses, and prohibits hall call allocation based on this, and determines an operation plan evaluation program to set an operation plan evaluation in the data table. A composite evaluation program is provided which evaluates at least the waiting time of the person and calculates the assigned evaluation value of each elevator based on the evaluation of the waiting time and the operation plan evaluation, and selects the call assigned elevator based on the combined evaluation value. At this time, for the elevators that arrive at the congested floor later, call allocation is performed in consideration of a car call expected to occur on the congested floor, such as suppressing hall call allocation farther than the congested floor.
[0011]
In addition, there is known an elevator guide display device that selects a guide display mode on a guide display device to provide a service status guide such as a long wait at a landing and displays the guide, and executes a reliable and accurate guide display (see below). See Patent Document 3.). This device sets the rules for displaying guidance according to the installation floor (layer) of the guidance display device installed at the landing, the direction of hall calls, and the traffic time zone, and selects a guidance display mode based on these rules to provide guidance. Display and suppress or prevent new hall calls and car calls according to the assigned conditions. According to the guidance display device, a service status such as "Please wait" or "I will arrive soon" is given in consideration of the long waiting of the passenger.

[0018]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0019]
(1st Embodiment)
FIG. 1 is a block diagram showing a schematic configuration of the elevator group management system according to the first embodiment of the present invention. The elevator group management system 1 shown in FIG. 1 provides an operation service for N cars 2A to 2N in an L-storey building. In particular, the elevator group management system 1 of the present embodiment generates a temporary hall call on a specific first floor (or a plurality of floors) such as a lobby floor where temporarily high demand is generated, for example, when going to work. The temporary hall call is a hall call that the elevator group management system 1 spontaneously generates without any operation by a passenger. In addition, for the generated temporary hall call, the elevator group management system 1 generates a temporary car call. The provisional car call defines a scheduled stop floor of the car assigned according to the provisional hall call. The planned stop floor of the car becomes a stop confirmed floor when a button is operated in the car by the passenger himself. On the specific floor where such temporary hall calls and car calls occur, car stop scheduled floor display boards 5A to 5N are installed. Each of the car stop scheduled floor display boards 5A to 5N corresponds to each of the cars 2A to 2N. In addition, a planned car stop floor list display plate 14 for displaying a list of planned stop floors of the cars of all the cars 2A to 2N is provided.
[0020]
On floors other than the specific floor, hall call devices 42, 43, to 4L are installed, respectively. The hall call devices 42, 43, to 4L are connected to the hall call device control unit 6. The hall call control unit 6 detects the occurrence of a hall call from the hall call units 42, 43, to 4L and notifies the allocation calculation unit 9 of the detection.
[0021]
The car call devices 3A to 3N are provided inside the baskets 2A to 2N, respectively. The car calling devices 3A to 3N are connected to the car calling device control unit 7. The car call device controller 7 detects the occurrence of a car call from the car call devices 3A to 3N and notifies the allocation calculator 9 of the occurrence.
[0022]
The car information detector 8 detects car information indicating the load, traveling direction, speed, and the like applied to the car from each of the cars 2A to 2N.
[0023]
A car assignment status table 12 and a car stop floor storage unit 13 are connected to the assignment calculation unit 9, and the assignment calculation unit 9 operates the car operation information detected by the car information detection unit 8, Based on the contents, the traffic flow in the building at that time, etc., the allocation calculation of the scheduled floors for stopping the cars 2A to 2N is performed. The result of the assignment calculation is sent to the car stop scheduled floor notification unit 11 and the car stop floor storage unit 13. The car stop floor storage unit 13 temporarily stores the result of the assignment calculation. The result of this allocation calculation is sent to the car allocation status table 12 when the cars 2A to 2N arrive at the floors where the planned car stop floor display boards 5A to 5N are installed. Thus, the scheduled stop floors of the cars 2A to 2N specified in the car assignment status table 12 are updated.
[0024]
The planned car stop floor notification unit 11 sends information indicating the planned car stop floors, which is the result of the allocation calculation by the allocation calculation unit 9, to the planned car stop floor display boards 5A to 5N and the planned car stop floor list display board 14. .
[0025]
The car operation control unit 10 controls the operation of each of the cars 2A to 2N, that is, starting, stopping, closing and opening doors, and moving.
[0026]
The operation of the present embodiment configured as described above will be described.
[0027]
Here, a case where four cars are operated in a building with 16 floors above ground (L = 15) will be described as an example.
[0028]
The elevator group management system 1 can appropriately determine the lobby floor (for example, the first floor) at a predetermined time interval (for example, one minute interval) according to the operation situation, for example, when going to work from 7:00 to 10:00 in the morning. A temporary hall call is generated at (preferred). As described above, since the temporary hall call is spontaneously generated by the elevator group management system 1, the passenger on the lobby floor does not need to perform the operation for the hall call.
[0029]
For the generated temporary hall call, the elevator group management system 1 generates a temporary car call. In this provisional car call, one or more floors scheduled to be stopped of the car assigned according to the provisional hall call are determined from the second floor to the 16th floor.
[0030]
FIG. 2 is a diagram showing an example of an appearance of a car stop planned floor display panel installation floor in the elevator group management system 1 according to the present embodiment, and FIG. 3 is a diagram showing an example of an appearance of a car stop planned floor list display panel.
[0031]
The car scheduled-stop floor display boards 5A to 5D shown in FIG. 2 can display characters, numerical values, symbols, and the like by, for example, electronic bulletin boards, and display the planned stop floors of the cars 2A to 2D. The planned car stop floor is a floor that is scheduled to be stopped after the cars 2A to 2N arrive at the floor on which the car stop floor display boards 5A to 5N are installed and depart. As for 2B, the second floor, the eighth floor, the twelfth floor, and the fourteenth floor are scheduled stop floors as can be seen from FIG. As described above, the scheduled floor for stopping the car generates a provisional car call for the car assigned according to the provisional hall call, and the assignment calculation unit 9 allocates the provisional car call based on the calculation. In some cases, such a car scheduled stop floor becomes a stop confirmed floor when a passenger performs a button operation in the car.
[0032]
As shown in FIG. 3, the planned car stop floor list display board 14 displays the planned stop floors of all the cars 2A to 2D, that is, the contents of the planned stop floors displayed on the planned car stop floor display boards 5A to 5D. List everything. Even if the passenger does not look at the car stop scheduled floor display boards 5A to 5D that are separately arranged for each elevator door, the car stop planned floor list display board 14 allows the car to be stopped on which floor. Can be listed.
[0033]
The passengers on the lobby floor are to wait for the car to be stopped at their destination floor (hereinafter, this one car is referred to as a basket 2k, where k is any of A to D) arrives at the lobby floor. Wait and get on when the car 2k arrives.
[0034]
Hereinafter, the procedure of the group management process when a passenger occurs on the lobby floor and a temporary hall call occurs at this time will be described with reference to the flowchart of FIG.
[0035]
(Step S1)
The assignment calculation unit 9 performs assignment processing of floors to be stopped of the cars 2A to 2N. The planned car stop floor display boards 5A to 5N display the respective planned stop floors of the cars 2A to 2N. The planned car stop floor list display panel 14 displays a list of planned stop floors for all of the cars 2A to 2N.
[0036]
(Step S2)
The car 2k arrives at the floor on which the car stop scheduled floor display plate 5k is installed.
[0037]
(Step S3)
At this time, the planned car stop floor storage unit 13 temporarily stores the planned stop floor after departure of the car 2k displayed on the planned car stop floor display panel 5k and the planned car stop floor list display panel 14. . The assignment status of the car 2k in the car assignment status table 12 is updated according to the contents of the scheduled car stop floor storage unit 13.
[0038]
(Step S4)
The passenger waits for the arrival of the car 2k scheduled to stop at his / her destination floor according to the display contents (planned stop floor) of the planned car stop floor display boards 5A to 5N or the planned car stop floor list display board 14. When the car 2k stopping at the destination floor arrives, the user gets on the car 2k.
[0039]
(Step S5)
As shown in FIG. 5, in the car call device 3k, when the passenger gets on the car 2k, the car call button b1 corresponding to the planned stop floor displayed on the planned car stop floor display board 5k blinks, Other car call buttons are turned off. According to the blinking display of the car call button b1 corresponding to the scheduled stop floor, the passenger who has boarded the car is prompted to make a car stop final registration on the destination floor.
[0040]
When the passenger presses one of the car call buttons b1 to designate his / her destination floor, car call registration is executed, and the process proceeds to step S6. The car call device 3k notifies the car call device control unit 7 that the car call registration to the destination floor of the passenger has occurred.
[0041]
(Step S6)
In step S5, the car call device control unit 7 determines whether or not the stop request floor designated by the passenger with the car call button b1 is the planned stop floor of the car 2k indicated on the planned car stop floor display panel 5k. . The determination can be made based on the car call assignment status table 12. If the requested floor is the planned floor of the car 2k, the process proceeds to step S7. On the other hand, when a car stop request is made by registering a car call to a floor other than the floor to be stopped, that is, a floor other than the floor that is blinking, the car call device control unit 7 checks the reference contents of the car allocation status table 12 with the reference contents. Then, it is determined that the floor is not the scheduled stop floor, and the process proceeds to step S8.
[0042]
(Step S7)
When the stop request floor designated by the passenger using the car call button b1 is the planned stop floor f of the car 2k indicated on the planned car stop floor display board 5k, the car call device control unit 7 sets the planned stop floor. It notifies the allocation calculator 9 that the car call registration to f has been performed. As a result, the stop on the floor is determined and registered, and the process proceeds to step S9.
[0043]
(Step S8)
The car call registration prohibited floor control for invalidating the car call registration performed in step S5 is activated, and the car call registration notification is not sent to the allocation calculator 9. In other words, in step S5, registration of a car call on a floor other than the floor on which the car 2k is to be stopped is prohibited.
[0044]
(Step S9)
The assignment calculation unit 9 operates the car assignment status table 12 to update the setting of the scheduled stop floor f to the setting of the stop confirmed floor f, and causes the car operation control unit 10 to stop the car at the stop confirmed floor f. Issue a command. The car operation control unit 10 updates the operation schedule of the car 2k so as to stop on the f floor, performs operation control to stop the car 2k on the f floor, and proceeds to step S10.
[0045]
(Step S10)
The car operation control unit 10 moves the car 2k to the floor f where the car stop has been confirmed and registered according to the operation schedule of the car 2k.
[0046]
(Step S11)
While the car 2k is moving, it is determined whether or not the car has passed the planned stop floor for which the car stop confirmation registration has not been performed. Regarding the floor to be stopped for which the stop confirmation registration by the car call of the passenger who has boarded is not performed even though it is the floor to be stopped, the car call button b1 of the car call device 3k corresponding thereto keeps blinking. Car stop confirmation registration must be performed before the car 2k passes the planned stop floor f.
[0047]
(Step S12)
When the car 2k passes through the planned stop floor, the planned stop floor f of the car 2k in the car assignment status table 12 is released from the scheduled stop, and the stop confirmation registration is not performed. The basket call button b1 corresponding to this passed floor changes from blinking to off.
[0048]
(Step S13)
When the car 2k arrives at the stop confirmed floor f, the passenger is disembarked, and the contents of the car assignment status table 12 are updated without stopping the decision to stop at the floor f, and the process ends.
[0049]
Here, the procedure of the car stop scheduled floor assignment processing (step S1) will be described in detail with reference to the flowchart of FIG.
[0050]
(Step S1-1)
The car 2k allows passengers to ride on the floor where the car is to be stopped and the door is closed, and the car closes before departure.
[0051]
(Step S1-2)
The assignment calculation unit 9 refers to the car assignment status table 12.
[0052]
(Step S1-3)
The car information detector 8 refers to the operation information of all the cars at the current time. This operation information is sent to the assignment calculation unit 9.
[0053]
(Step S1-4)
The allocation calculation unit 9 determines a planned floor for stopping the car 2k by a predetermined planned floor allocation calculation process based on the contents of the referenced car allocation status table 12 and the operation information. The number of floors to be stopped may be a single floor or a plurality of floors.
[0054]
(Step S1-5)
The determined planned floor of the car 2k to be stopped is sent to the planned car stop floor notifying unit 11 and stored in the planned car stop floor storage unit 13.
[0055]
(Step S1-6)
The planned car stop floor notification unit 11 updates the contents of the planned stop floor display on the planned car stop floor display board 5k of the car 2k and the contents of the planned stop floor list display on the car stop planned floor list display board 14, and stops the car. The scheduled floor allocation process ends.
[0056]
Passengers who occur while the car 2k is not at the car stop scheduled floor display board installation floor are shown the car 2k stop planned floor after departure after the car 2k arrives at the car stop planned floor display board installation floor next time. According to the display contents of the planned car stop floor display panel 5k or the display contents of the planned car stop floor list display panel 14, if the car is to be stopped at its destination floor, it waits for the arrival of the car 2k. Passengers generated on floors other than the floor where the car will be stopped will be registered as hall calls using hall call devices 42, 43, and 4L provided for each floor, and the car 2 will be registered in the elevator group management system. Make a vehicle allocation request.
[0057]
Next, a procedure of a hall call service process when a hall call occurs when steps S1 to S13 of FIG. 4 are executed will be described with reference to a flowchart of FIG.
[0058]
(Step S113-1)
It is assumed that the passenger presses the hall call button in the d direction on the i-th floor (here, i = 2 to L) other than the specific floor described above.
[0059]
(Step S113-2)
The hall call controller 6 detects that the hall call button of the hall call device 4i in the d direction has been pressed on the i-th floor, and notifies the allocation calculator 9 of this.
[0060]
(Step S113-3)
The assignment calculation unit 9 performs a car assignment process for the hall call, sends the result to the car operation control unit 10, and updates the car assignment status table 12. Here, it is assumed that the same basket 2k as the one noticed in FIG. 4 is assigned. The details of step S113-3 will be described later (see FIG. 8).
[0061]
(Step S113-4)
The car operation control unit 10 updates the operation schedule of the car 2k according to the car assignment result calculated in step S113-3, and allocates the car 2k to the i-th floor.
[0062]
(Step S113-5)
When the car 2k arrives at the i-th floor, the car call prohibition registration floor control for prohibiting the car call except the floor to be stopped is released. After the cancellation, the car call can be performed on all floors. Here, it is determined whether there is a disembarking customer. If there is a disembarking customer, the process proceeds to step S117-7, and if there is no disembarking customer, the process proceeds to the next step S113-6.
[0063]
(Step S113-6)
The boarding process of the passenger who made the hall call on the i-th floor is performed. This passenger can make a car call to the destination floor. The car call prohibition registration floor control has been released. Next, the process proceeds to step S113-8.
[0064]
(Step S113-7)
The dismounting process is performed, and the process proceeds to the boarding process in step S113-6.
[0065]
(Step S113-8)
The car 2k departs from the i-th floor and moves to the passenger's destination floor.
[0066]
(Step S113-9)
The car 2k arrives at the destination floor of the passenger who made the car call. Let this passenger get off.
[0067]
As can be seen from the above step S113-5, during operation based on the provisional hall call on the specific floor (steps S1 to S13 in FIG. 4), the basket responds to a hall call from a passenger on another floor. When assigned, the car call prohibition registration floor control is released, so that it is possible to appropriately provide services to passengers from the other floors. In other words, the operation based on the temporary hall call on the specific floor can be implemented so as not to hinder the normal operation corresponding to the hall call from another floor.
[0068]
Here, the detailed procedure of the allocation process in step S113-3 will be described with reference to the flowchart in FIG.
[0069]
(Step S113-31)
It is assumed that a hall call to the d direction occurs on the i-th floor.
[0070]
(Step S113-32)
The allocation calculation unit 9 refers to the car allocation status table 12 and searches for a car that is scheduled to stop at the i-th floor or that has been determined to stop at the i-th floor. FIG. 9 shows a configuration example of the car assignment status table 12. The car allocation status table 12 has a floor buffer for each car, and one of a planned stop floor flag P and a stop confirmed floor flag D is set. According to the planned stop floor flag and the stop confirmed floor flag, it is possible to determine on which floor each car is to be stopped and on which floor the stop is confirmed. In the example of FIG. 9, it can be seen that the second floor of the car 22 is the stop confirmed floor, and the third floor and the L floor are the scheduled stop floors.
[0071]
As a result of such a search of the car assignment status table 12, if a car scheduled to stop at the i-th floor or a car that has been determined to be stopped is found, the process proceeds to step S113-34. Proceed to -33.
[0072]
(Step S113-33)
The allocation calculation unit 9 uses the hall call device control board 6, the car call device control plate 7, the car information detection unit 10, and the car assignment status table 12 to generate the hall call and car calls, the current position of all the cars, and the progress of the car. Information such as the direction, current load, stop confirmed floor, planned stop floor, etc. is obtained, and the process proceeds to step S113-35.
[0073]
(Step S113-34)
The allocation calculation unit 9 changes the stop of the basket scheduled to stop on the i-th floor to the stop on the i-th floor to be determined (confirmed), and proceeds to step S113-37.
[0074]
(Step S113-35)
The allocation calculation unit 9 executes a predetermined allocation evaluation calculation for each of all the cars, and, based on the result of the allocation evaluation calculation, determines the allocation to, for example, the car 2k (car k) (determines the vehicle allocation).
[0075]
(Step S113-36)
The assignment calculation unit 9 updates the car assignment status table 12 based on the result of the car assignment in step S113-35.
[0076]
(Step S113-37)
The above allocation result is sent to the car operation control unit 10, and the allocation process is completed. Here, when the assigned car 2k is on the floor on which the planned car stop floor list display panel 14 is installed, the result of the allocation is also sent to the car stop planned floor notification unit 11. As a result, the floor on which the hall is called is also added as the planned stop floor on the planned car stop floor display board 5k that displays the planned stop floor of the car 2k.
[0077]
On the other hand, if it is determined in step S113-33 that the floor on which the hall call has been made is the stop confirmed floor or the planned stop floor of the car 2k, the car 2k is allocated and determined in step S113-35, and step S113-35 is performed. Proceed to 38.
[0078]
(2nd Embodiment)
The second embodiment relates to a modification of the above-described first embodiment. As shown in FIG. 10, in the configuration of the second embodiment, a car stop scheduled floor display board and a car stop scheduled floor list display board are installed on all floors without installing a hall call device.
[0079]
A set 4i (i = 1, 2, to L) of a scheduled car stop floor display panel 5A to 5N of each car and a scheduled car stop floor list display panel 14 is installed on each floor. In this case, since no hall call is generated by the passenger from any floor, the hall call service processing described with reference to FIG. 7 is unnecessary.
[0080]
According to the first and second embodiments described above, passengers who use the elevator may ride on the car according to the display contents of the planned car stop floor display panel (or the planned car stop floor list display panel). It is not necessary to make a hall call and issue a car service request to the elevator group management system 1 as described above. Therefore, the operation burden and psychological burden due to hall calls and the like can be reduced.
[0081]
On the other hand, the group management side that provides the car dispatch service to the passengers does not need to predict the exit floor of the passenger who generated the hall call in response to the service request by the hall call. For this reason, it is possible to avoid complaints from passengers when the waiting time and the service time increase due to mispredictions.
[0082]
Further, one of the features of the present invention is to give the elevator group management side the right to make a decision on the dispatch of a car. According to this, demand concentrates on a specific floor such as when going to work, and the floor is shifted from the lobby floor to another floor. When there are many passengers heading for the elevator, the elevator group management side can independently and efficiently perform the car assignment to service these passengers. For example, passengers can be guided by notifying the passengers of the scheduled stop floor of each car. Accordingly, the group management side can control not only the passenger transportation in the building but also the traffic flow in the building.
[0083]
The present invention is not limited to the above-described embodiment, and can be implemented with various modifications.
