In the figure, reference numeral 10 denotes a group management device, and the group management device 10 grasps the traffic condition of the elevator based on a signal of a car control device and a landing button provided in each elevator car, a running state of each car, and the like. The purpose of the present invention is to improve elevator operation efficiency by performing optimal car assignment.
Next, the configuration of the group management device 10 according to the present invention will be described. Reference numeral 1 denotes a group management allocating means for allocating an elevator car. The group management allocating means 1 assigns one of a plurality of elevators to respond when a passenger presses a hall button at a hall. Group management operation control means. Reference numeral 2 denotes a traffic condition determining unit that recognizes and determines the traffic condition of the elevator.

FIG. 2 is a flowchart showing the operation of the elevator group management apparatus 10 according to the present invention. Next, the operation of the elevator group management device 10 will be described with reference to the flowchart of FIG. This processing flow is started periodically. First, the elevator group management device 10 determines whether a new hall call has occurred (step S21), and when a new hall call has occurred, determines the traffic situation (step S2).
2). Next, after performing the traffic condition determination, the elevator group management device 10 determines an assigned car for the hall call based on the result (Step S23).

FIG. 3 is a flow chart showing the traffic condition determination in step S22 of FIG. First, traffic condition determination means 2
Determines whether the car is scheduled to stop on the floor immediately before the newly generated hall call (step S231), and then determines whether the car is scheduled to be stopped on the floor ahead of the newly generated hall call. (Step S232).

FIG. 4 is a flowchart showing the detailed operation of the pre-caller stop determination in step S231 in FIG. Next, this flowchart will be described. The traffic condition determining means 2 constantly manages the traveling direction of the car and the position of the car. In step S2401, it is determined whether there is a new hall call in the traveling direction of the car. In this case, the traffic condition determination means 2 determines from the position of the hall call, the position of the car, and the traveling direction. For example, in a building on the 10th floor, when the car is on the 1st floor and traveling to the 6th floor, 4
If there is a landing call on the floor, the traffic situation determination means 2 determines that there is a landing call in the traveling direction of the car. If there is no new hall call in the traveling direction of the car, the process moves to step S2410. If there is a new hall call in the traveling direction of the car, it is determined in step S2402 whether the direction of the hall call and the traveling direction of the car are the same. If the direction of the hall call is different from the traveling direction of the car, the process moves to step S2410. If the direction of the hall call and the traveling direction of the car are the same direction, it is determined in step S2403 whether or not there is a scheduled stop at the hall call occurrence floor. If there is no scheduled stop at the hall call occurrence floor, step S2410
Move to If there is a scheduled stop at the floor call occurrence floor, it is determined in step S2404 whether or not there is a stop plan immediately before the floor call occurrence floor. If there is no scheduled stop before the hall call occurrence floor, the process moves to step S2410.

If there is a stop scheduled before the floor call occurrence floor, it is determined in step S2405 whether a plurality of stop floors before the hall call exist. If there are a plurality of stop floors before the hall call, the stop floor closest to the hall call is set as the nearest stop floor in step S2406, and then step S2406 is performed.
Move to 2408. If there is no plurality of stop floors in front of the hall caller and there is only the first floor, in step S2407, the planned stop floor is set as the nearest stop floor, and the process proceeds to step S2408.
The traffic condition determination means 2 calculates the distance from the hall call occurrence floor to the nearest stop floor in step S2408 by calculating the number of floors between the two and the distance per floor, and the calculated distance indicates that the vehicle is traveling. It is determined whether or not the car is shorter than a distance enough to reach the rated speed (this distance Sa is assumed to be known in advance). (The determination as to whether or not to reach the rated speed can be derived from the car acceleration and the traveling distance, and is a known technique.)

If the traffic condition determining means 2 determines that the speed of the car has reached the rated speed when the car has traveled from the hall call occurrence floor to the nearest stop floor, the process proceeds to step S2410. If the traffic condition determination means 2 determines that the speed of the car does not reach the rated speed when the car has traveled from the hall call occurrence floor to the nearest stop floor, the front stop flag is set to the corresponding car in step S2409. Is set. Therefore, a car for which the front stop flag is set means a car having a problem. Next, in step S2410, it is determined whether or not the determination of all elevators has been completed.
Returning to 01, the same check is performed for other cars.
If it is determined in step S2410 that all cars have been completed, the process ends. Therefore, the front stop flag needs to be provided for each elevator.

FIG. 5 is a flow chart showing the call destination stop determination in step S232 in FIG. Next, this flowchart will be described. Traffic condition determination means 2
In step S2501, it is determined whether there is a new hall call in the traveling direction of the car. If there is no new hall call in the traveling direction of the car, the process moves to step S2510. If there is a new hall call in the traveling direction of the car, it is determined in step S2502 whether the direction of the hall call and the traveling direction of the car are the same. If the direction of the hall call is different from the traveling direction of the car, the process moves to step S2510. If the direction of the hall call and the traveling direction of the car are the same direction, it is determined in step S2503 whether or not there is a plan to stop at the hall call occurrence floor. If there is no scheduled stop at the hall call occurrence floor, the process moves to step S2510. If there is a stop at the hall call occurrence floor, it is determined in step S2504 whether or not there is a stop at the end of the hall call occurrence floor. If there is no scheduled stop on the other side of the hall call occurrence floor, step S251
Move to 0.

If there is a scheduled stop on the floor ahead of the hall call occurrence floor, it is determined in step S2505 whether a plurality of the hall call destination stop floors exist. If there are a plurality of stop floors at the hall call destination, the stop floor closest to the hall call is set as the nearest stop floor in step S2506, and then step S2 is performed.
Move to 508. In the case where there are not a plurality of stop floors at the hall call destination and only the first floor, the planned stop floor is set as the nearest stop floor in step S2507, and the process proceeds to step S2508.
The traffic situation determination means 2 calculates the distance from the hall call occurrence floor to the nearest stop floor in step S2508 by calculating the number of floors between the two and the distance per floor, and the calculated distance is calculated as the travel distance. It is determined whether or not the inside car is a distance enough to reach the rated speed (this distance is assumed to be known in advance). (The determination as to whether or not to reach the rated speed can be derived from the car acceleration and the traveling distance, and is a known technique.)

If the traffic condition determining means 2 determines that the speed of the car has reached the rated speed when the car has traveled from the hall call occurrence floor to the nearest stop floor, the flow proceeds to step S2510. If the traffic condition determining means 2 determines that the speed of the car does not reach the rated speed when the car has traveled from the hall call generation floor to the nearest stop floor, a forward stop flag is given to the corresponding car in step S2509. Is set. Therefore, the car for which the destination stop flag is set means a car having a problem. Next, in step 2510, it is determined whether or not the determination of all elevators has been completed. If the determination of all elevators has not been completed, the process returns to step 2501, and the same check is performed for other cars. If all the units have been terminated in the determination of step 2510,
The process ends. Therefore, the forward stop flag needs to be provided for each elevator.

FIG. 6 is a flowchart showing the operation of the group management allocating means 1 shown in FIG. Next, the operation of the group management allocating means 1 will be described with reference to FIG. In step S1301, when a hall call occurs, the estimated arrival time calculation program calculates the estimated arrival time of the car to the floor where the hall call was made when the hall call is assigned to the car. , In step S1320,
The allocation restriction detection program determines whether or not the allocation is restricted (whether the car to which the hall call is allocated is already full or is out of order, such as a state where the waiting time of the passenger is prolonged). ) Is detected, and then step S1
At 303, the waiting time evaluation program calculates the waiting time evaluation value of the car, and then, at step S1304, the assigned car determination program sets the expected car arrival time, which is the output from the expected arrival time calculation program, The car to be assigned is determined based on the output from the detection program as to whether or not the assignment is restricted and the car waiting time as the output from the waiting time evaluation program.

FIG. 7 is a flowchart showing the detailed operation of the allocation restriction detecting program in step S1320 in FIG. Next, the operation of the allocation restriction detection program will be described with reference to FIG. This allocation restriction detection program is started in each car every time a hall call occurs. First, in step S 13201, it is determined whether the car is traveling in the direction opposite to the direction of the hall call. The direction in which the car moves away from the floor where the hall call was made (hereinafter, the opposite direction)
If it is running at step S13204, the process moves to step S13204. If the car is not traveling in the direction opposite to the hall call direction, it is determined in step S13202 whether the car load is equal to or greater than a predetermined value. If the car load is equal to or more than the predetermined value, the process moves to step S13204. In addition, about car load,
The measurement is performed by a measured value from a known weighing device provided in the elevator. If the car load is not above the default,
In step S13203, it is determined whether the elevator does not reach the rated speed. In this determination, the front stop flag and the forward stop flag set in FIGS. 4 and 5 are referred to. When the allocation limiting unit 1302 detects that the rated speed has not been reached as a result of referring to the flag, the process proceeds to step S13204. In step S13204, an allocation restriction flag is set. This allocation restriction flag is shown in FIG.

In step S1301, the estimated arrival time calculation program calculates the expected arrival time of the car by calculation.
At 340, the allocation penalty giving program gives a different penalty value according to the state of the car. Next, at step S1303, the waiting time evaluation program calculates the waiting time evaluation value of the car, and then at step S1304. In the allocated car determination program, the expected car arrival time output from the expected arrival time calculation program, the allocation penalty value output from the allocation penalty grant program,
The car to be assigned is determined based on the car waiting time, which is the output from the waiting time evaluation program.

FIG. 9 is a flowchart showing the detailed operation of the allocation penalty giving program in step S1340 of FIG. Next, the operation of the assignment penalty giving program will be described with reference to FIG. This assigned penalty giving program is started in each car every time a hall call occurs. First, in step S13401,
Initialize the car allocation penalty to zero. Next, in step 13402, it is determined whether or not the car is traveling in a direction opposite to the direction of the hall call. If the car is traveling in the direction opposite to the hall call direction, the penalty value (here, 100) is added to the assigned penalty in step 13403, and the process proceeds to step S13404. If the hall call and the car are not traveling in the opposite direction, the process advances to step S13404. In step S13404, it is determined whether the car load is equal to or greater than a predetermined value. If the car load is equal to or more than the predetermined value, the penalty value (here, 200) is added to the allocation penalty in step S13405, and then the process proceeds to step S13405.
Proceed to 13406. If the car load is not above the default,
Proceed to step S13406.

In step S13406, it is determined whether or not the elevator has not reached the rated speed. In this determination, the front stop flag and the forward stop flag set in FIGS. 4 and 5 are referred to. If the assignment penalty assignment program S1340 detects that the rated speed has not been reached as a result of referring to the flag, the process moves to step S13407. In step S13407, a penalty value (here, 400) is added to the allocation penalty. Note that the penalty value added here can be arbitrarily changed. This penalty value is used in the assigned car determination program of FIG. 8 and is used as one element of the assigned car determination. For example, control can be performed so that a car having a higher penalty value is not allocated as much as possible. For example, in the above example, the penalty value is 700 (700 = 400 + 2).
The car (00 + 100) means that there is a problem under all conditions, so this car is least assigned.

First, in step S13501, it is determined whether or not the hall call and the car are running in the opposite direction. If the hall call and the car are traveling in the opposite direction, step S1350
Move to 4. If the hall call and the car are not traveling in the opposite direction, it is determined in step S13502 whether the car load is equal to or greater than a predetermined value. If the car load is equal to or more than the predetermined value, the process moves to step S13504. If the car load is not equal to or greater than the predetermined value, it is determined in step S13503 whether the elevator does not reach the rated speed. In this determination, FIG.
The front stop flag and the forward stop flag set in FIG. 5 are referred to. If the allocation prohibition detecting program detects that the rated speed has not been reached as a result of referring to the flag, the flow proceeds to step S13504. Step 13504
Sets the assignment prohibition flag. This allocation prohibition flag is used when deciding an allocated car by the allocation car determination program of FIG. 10, and a car having the allocation prohibition flag is excluded from the allocation for the hall call. Therefore, it is necessary to provide an assignment prohibition flag for each elevator.

In step S1304, the waiting time evaluation program calculates the waiting time evaluation value of the car. In step S1304, the assigned car determination program determines whether or not the expected car arrival time is an output from the expected arrival time calculation program and the number of abnormalities. The car to be assigned is determined based on the number of abnormalities output from the program and the car waiting time output from the waiting time evaluation program.

FIG. 13 is a flowchart showing the detailed operation of the abnormality count detection program in step S1360 in FIG. Next, the operation of the abnormality number detection program will be described with reference to FIG. The abnormality number detection program is activated for each time zone, every time a hall call occurs, for each direction of the hall call, and for each car. First, step S13
At 601, it is determined whether the elevator does not reach the rated speed. For this determination, the front stop flag and the forward stop flag set in FIGS. 4 and 5 are referred to. If the rated speed is not reached as a result of referring to the flag, the flow shifts to step S13602. In step S13602, if the rated speed has not been reached, one is added to the counter.
