[1] First Embodiment FIG. 1 is an explanatory diagram of a configuration example of an elevator control system according to an embodiment.
The elevator control system 10 is roughly divided into a plurality of (three in the example of FIG. 1) elevators 11, an elevator control device 12 that performs group management control of the elevators 11, and each elevator under the control of the elevator control device 12. 11 and a destination floor registration device 14 provided at the landing of the elevator 11 .

In the following description, when it is necessary to identify each elevator 11, they are referred to as elevator 11A (A car), elevator 11B (B car) and elevator 11C (C car).

Each car of the elevator 11 is provided with an announcement device for making various announcements.

When the destination floor registration device 14 issues a destination floor call (platform call), the elevator control device (group control device) 12 registers the destination call already assigned to the elevator 11A, the elevator 11B, and the elevator 11C or the elevator Based on the already assigned car calls corresponding to 11A, elevator 11B and elevator 11C, determine which elevator will respond to the new destination floor call and output an assignment command.

In this case, as will be described later, the elevator control device 12 determines the elevator demand, and if the demand is equal to or less than a predetermined value (predetermined threshold value), more specifically, the predicted average waiting time for the registered destination call When the time is equal to or less than a predetermined threshold, the allocation of a new destination floor call corresponding to a floor on the way to the already-allocated destination floor call registration floor is suppressed, and a new destination floor call corresponding to the floor on the way to the car call registration floor is suppressed. Control is performed so as to suppress allocation of destination floor calls.

The single controller 13 controls the running of the car and the door opening/closing of any one of the corresponding elevators 11 .

The destination floor registration device 14 is installed at the hall of the elevator 11, registers the inputted destination floor, and generates a destination call.

More specifically, at least one destination floor registration device 14 is installed at each hall of the elevator 11 . The destination floor registration device 14 includes a registration button panel 14A having a plurality of registration buttons for passengers to register their destination floors, a wheelchair button 14B for wheelchair users to call a wheelchair-compatible double-deck elevator, A display panel 14C for displaying various information is provided.

A passenger can register a desired destination floor by operating the registration button for each floor on the registration button panel 14A. When the destination floor is registered, a destination call signal indicating the destination floor is sent from the destination floor registration device 14 to the elevator control device 12 .
These registration information are displayed on the display panel 14C.

Here, functions of the elevator control device 12 will be described.
The allocation control unit 21 of the elevator control device 12 manages the destination floor call registration corresponding to the actually registered destination floor call registration floor and the information specifying the corresponding elevator, and normally, each car of the elevators 11A to 11C A car to be assigned to a destination call is determined based on each assigned evaluation value calculated for each.
Also, the allocation control unit 21 predicts the waiting time from when the destination floor call is registered until the car arrives and calculates it as a predicted average waiting time.

In addition, during the ride-sharing suppression control, the allocation control unit 21 assigns cars to suppress ride-sharing in response to destination floor calls based on the calculation result of the number of passengers in each car calculated for each car of the elevators 11A to 11C. to decide.

Then, when the car to be assigned corresponding to the destination floor call is determined, the allocation control unit 21 outputs an allocation command corresponding to the car to the corresponding unit control device 13 .
In this case, the allocation control unit 21 includes a judgment unit 21A for judging whether or not it is necessary to suppress the number of passengers in the elevator car from exceeding a predetermined number, and a a car allocation exclusion unit 21B that excludes from the allocation target a car that is likely to be shared by more than a predetermined number of people, based on the registered landing destination call when it is necessary to suppress the It functions as a standing position presentation unit 21C that presents a standing position with a high priority among unassigned standing positions based on preset standing positions of passengers and standing position priorities.
In addition, the standing position priority setting unit 22 can set the priority of the standing position, which will be described later, and stores the priority of the standing position in the car.

Next, the general operation of the first embodiment will be described.
FIG. 2 is an overall processing flowchart of the first embodiment.
First, the elevator control device 12 determines whether or not it is necessary to carry out a car-sharing suppression control to reduce the number of passengers in the car and avoid a crowded state in the car (step S11).

In this case, whether or not the car-sharing suppression control is necessary is determined when the predicted average waiting time is below a certain level, that is, when the predicted average waiting time is short and the congestion in the car is unlikely to occur, or This is the case where the setting switch or the like is set by the elevator manager so that the control of the suppression of boarding is always performed.

If it is determined in step S11 that the ride-sharing suppression control is not necessary (step S11; No), the elevator control device 12 shifts the process to step S14 and performs car allocation evaluation as usual (step S14). Vehicle allocation control is performed (step S15). Details of allocation evaluation will be described later.

If it is determined in step S11 that the ride-sharing suppression control is necessary (step S11; Yes), the elevator control device 12 calculates the number of passengers in the car (step S12).

FIG. 3 is a processing flowchart of the calculation processing of the number of passengers in the car.
This process of calculating the number of passengers in the car is performed for all the elevators 11, that is, for each of the elevators 11A to 11C.
More specifically, the elevator control device 12 determines the maximum number of ride-sharing states from the boarding and alighting floors of already boarded passengers and the boarding/alighting floor of the destination call already assigned to the elevator 11 until the passenger of the new destination call gets off. The number of people is calculated (step S21).
Then, similar processing is performed for all elevators 11 .

Next, the elevator control device 12 performs allocation candidate car selection processing (step S13).

FIG. 4 is a processing flowchart of selection processing of allocation candidate cars.
The allocation candidate car selection process is performed for all the elevators 11, that is, for each of the elevators 11A to 11C.

More specifically, the elevator control device 12 determines the maximum number of people who will be in a shared ride state from the scheduled alighting floor of the already-boarded passengers calculated in step S21 and the boarding/alighting floor of the already assigned destination call until the passengers of the new destination call get off. It is determined whether or not the number exceeds a predetermined number (step S31).

If it is determined in step S31 that the maximum number of people who will be in a shared ride state from the planned alighting floor of already-boarded passengers and the boarding/alighting floor of the already-assigned destination call until the passenger of the new destination call alights does not exceed the predetermined number of people. If (step S31; No), the allocation candidate car selection process ends.

In the judgment of step S31, if the maximum number of people who will be in a shared state from the floor where the already boarded passenger is scheduled to get off, the boarding/alighting floor of the already-allocated destination call, to the passenger of the new destination call getting off, exceeds a predetermined number of people. Since there is a high possibility that the car corresponding to the elevator 11 will be in a dense state, it is excluded from allocation candidate cars (step S32).

Next, the elevator control device 12 performs allocation evaluation processing for the selected allocation candidate car (step S14).

FIG. 5 is a processing flowchart of allocation evaluation processing.
The allocation evaluation process is a process of selecting the elevator 11 to run from among the allocation candidate cars in response to the actual destination call.

More specifically, the elevator control device 12 determines whether or not there is an allocation candidate car as a result of the determination in step S31 (step S41).
In the judgment of step S41, if there is at least one allocation candidate car (step S41; Yes), the elevator control device 12 performs normal allocation evaluation from among the allocation candidate cars, and based on the allocation evaluation, An actual assigned car is selected (determined) (step S42).

Then, the elevator control device 12 registers the selection result of the assigned car as the landing destination floor (step S43), and ends the assignment evaluation process.
In the judgment of step S41, if there is no allocation candidate car (step S41; No), the elevator control device 12 judges that there is no allocation (step S44), and registers the selection result of the allocation car to the landing floor. (Step S43), the allocation evaluation process is terminated.

Next, the elevator control device 12 performs vehicle allocation control for the car registered for the destination floor (step S15).
As a result of these processes, at the hall corresponding to the hall destination floor registration, a car that is considered to limit the number of people at the time of sharing is allocated.

As described above, according to the first embodiment, it is possible to prevent the maximum number of people in the car sharing state from exceeding the number of people specified in advance and the inside of the car of the elevator to become dense.
Therefore, it is possible to prevent more than a predetermined number of people from riding together in the car of the elevator and to ensure a social distance.

[2] Second Embodiment Next, a second embodiment will be described.
The second embodiment differs from the first embodiment in that it presents the passengers in the car with a suitable standing position for ensuring social distance.

FIG. 6 is a diagram illustrating an example of a suitable standing position within an elevator car.
The car BX of the elevator 11 has a passenger standing position for ensuring a more suitable social distance according to its size.

For example, in the car BX shown in FIG. 6, standing positions P1 to P5 are conceivable in consideration of the position of the in-car operation panel.
In this case, the priorities of the standing positions P1 to P5 (standing position priorities) PP1 to PP5 are, for example, as follows.
PP1>PP2>PP3>PP4>PP5

In this way, by assigning standing positions to passengers in descending order of priority and setting the maximum number of passengers at the time of carpooling to five, a favorable social distance can be ensured.

Next, the operation of the second embodiment will be explained.
FIG. 7 is an overall processing flowchart of the second embodiment.
In FIG. 7, parts similar to those in FIG. 2 are given the same reference numerals.
First, the elevator control device 12 determines whether or not it is necessary to carry out a car-sharing suppression control to reduce the number of passengers in the car and avoid a crowded state in the car (step S11).

If it is determined in step S11 that the ride-sharing suppression control is not necessary (step S11; No), the elevator control device 12 shifts the process to step S46 and performs car allocation evaluation as usual (step S46). Vehicle allocation control is performed (step S47).

If it is determined in step S11 that the ride-sharing suppression control is necessary, and if the current operation mode is the congestion avoidance operation mode (step S11; Yes), the elevator control device 12 follows the procedure shown in FIG. The number of passengers in the car is calculated (step S12).

Next, the elevator control device 12 performs allocation candidate car selection processing according to the procedure shown in FIG. 4 (step S13).

In the judgment of step S31, if the maximum number of people who will be in a shared state from the floor where the already boarded passenger is scheduled to get off, the boarding/alighting floor of the already-allocated destination call, to the passenger of the new destination call getting off, exceeds a predetermined number of people. Since there is a high possibility that the car corresponding to the elevator 11 will be in a dense state, it is excluded from allocation candidate cars (step S32).

Next, the elevator control device 12 performs allocation evaluation processing for the selected allocation candidate car (step S46).

FIG. 8 is a processing flowchart of allocation evaluation processing.
The allocation evaluation process is a process of selecting the elevator 11 to run from among the allocation candidate cars in response to the actual destination call.
More specifically, the elevator control device 12 determines whether or not there is an allocation candidate car as a result of the determination in step S31 (step S51).

In the judgment of step S51, if there is at least one allocation candidate car (step S51; Yes), the elevator control device 12 performs normal allocation evaluation from among the allocation candidate cars, and based on the allocation evaluation, An actual assigned car is selected (determined) (step S52).

Next, the elevator control device 12 performs a car standing position determination process (step S53).

FIG. 9 is a processing flowchart of the car standing position determination processing.
First, the elevator control device 12 sets a predetermined standing position (corresponding to the standing positions P1 to P5 described above) according to the size of the car stored from the standing position priority setting unit 22, and the standing position priority ( (corresponding to the above-mentioned priorities PP1 to PP5) are obtained (step S61).

Next, the elevator control device 12 selects the standing position with the highest priority among the unassigned standing positions as the standing position information to be presented when boarding the assigned car at the destination floor of the new destination call (step S62). ).

More specifically, in the initial state, the highest priority standing position P1 (priority=PP1) is selected from the standing positions P1 to P5.
In a state where the standing positions P1 and P2 have already been selected, the standing position P3 (priority=PP3) with the highest priority among the unassigned standing positions P3 to P5 is selected.

Next, the elevator control device 12 notifies the destination floor registration device 14 of the hall of the selection result of the assigned car and the standing position determination result, and ends the assignment evaluation process (step S54).

Next, the elevator control device 12 performs dispatch control for the car registered for the destination floor, and presents the standing position information in the destination floor registration device 14 (step S47).
As a result of these processes, at the hall corresponding to the hall destination floor registration, a car that is considered to limit the number of people at the time of carpooling is allocated and position information is presented.

FIG. 10 is an explanatory view of the external appearance of the destination floor registration device when the standing position result is displayed.
FIG. 11 is a detailed explanatory diagram of the standing position result display of the destination floor registration device.
The notified assigned car selection result EID and standing position determination result STP are displayed on the display panel 14C of the destination floor registration device 14, as shown in FIG.

More specifically, as shown in FIG. 11, it can be seen from the selection result EID of the assigned car that the assigned car is the "A" car corresponding to the elevator 11A.
Also, as a preferred standing position of the passenger recommended by the elevator control device 12, a standing position indication mark STM corresponding to the standing position P1 is shown together with a schematic diagram of the car.

In this case, the other standing positions P2 to P5 are displayed in gray or the like.
If necessary, it is also possible to provide voice guidance or a guidance display on the display panel 14C so that the user stands on the standing position display mark STM to board the vehicle.

As described above, according to the second embodiment, it is possible to prevent the maximum number of people in the car sharing state from exceeding a predetermined number of people, thereby preventing the inside of the elevator car from becoming crowded. Since it is possible to present suitable standing positions of passengers, it is possible to prevent more than a predetermined number of people from riding together in an elevator car, and to ensure social distance more reliably.
