This elevator car allocator works on the main floor (usually 1
When there is a large amount of traffic for landing calls for floors (upstairs), if a landing call for landing on the main floor and a landing call for basement floors are registered, the cars that responded to these landing calls will have a time interval equal to that on the main floor. It assigns the cars to arrive.
By allocating the cars in this way, congestion on the main floor floor is averaged and waiting passengers on the main floor are prevented from waiting for a long time.

Further, in the above elevator car allocating device, since the main floor is limited to one floor, it is not suitable when there are a plurality of main floors. In particular, the arrival of a subway train causes the basement floor to become the main floor, and the arrival of a train that is an underground transportation means the basement floor becomes the main floor, depending on the arrival of each train. However, when the floor that becomes the main floor changes with the passage of time, it was not possible to provide equal service to these two main floors.

However, in the technologies disclosed in the above-mentioned publications, since the main floor is limited to the first floor above the ground, only the service of the main floor above the ground is improved, and the service of the main floor below is improved. Since it is not done, it was inconvenient like the former when the main floor also existed in the basement. In addition, the underground floor becomes the main floor due to the arrival of a subway train, and the first floor above the ground becomes the main floor due to the arrival of a train that is a ground transportation system. In the case where the floor which becomes the main floor changes with the passage of time in response to the arrival of the above, it is still unsolved to provide equal service to these two main floors.

In the figure, in step S1, it is determined whether or not hall calls in the same direction are simultaneously generated from the two main floors, the first floor and the B floor. This is the first floor landing call signal to the allocation arithmetic unit 1.
It can be judged by inputting 1U and B floor hall up signal BU at the same time. When no hall calls in the same direction are simultaneously generated from the two main floors, the elevator car allocating operation is not performed. If the hall calls in the same direction are simultaneously generated from the two main floors on the first and B floors, the loading load on the two main floors on the first and B floors during the past 5 minutes in step S2. Find the ratio X. This is calculated by X = (cumulative boarding load value due to first floor landing call for the past 5 minutes) ÷ (cumulative boarding load value due to floor B landing call for the past 5 minutes). Then, in step S3, the allocation ratio Y when the first floor is allocated is obtained. This is calculated by Y = (cumulative value for 1st floor hall upcoming call in the past 5 minutes + 1) ÷ (cumulative value for B floor hall upcoming call in the last 5 minutes). Subsequently, in the same manner, the allocation ratio Z when the floor B is allocated in step S4 is obtained. That is, Z = (cumulative value for 1st floor landing call for the past 5 minutes) / (cumulative value for B floor landing call for the last 5 minutes + 1). Then, in step S5, the absolute value M (= | X−Y |) of the difference between the boarding load ratio X and the allocation ratio Y is obtained,
At S6, the absolute value N (= | X− of the difference between the boarding load ratio X and the allocation ratio Z
Z |). Then, in step S7, the above absolute values M
And the magnitude of N are compared, and when M is smaller than N, step
Proceed to S8 and assign a car to the hall upcoming call on the first floor. When M is N or more, the process proceeds to step S9, and a car is assigned to the hall upcall on the B floor. By repeating this series of routines, elevator cars are appropriately allocated to the first floor and the B floor.

Here, the elevator car allocating operation will be described with reference to specific numbers. For example, when the landing load ratio (traffic ratio) of the first floor and the Bth floor is 3: 4, the boarding load ratio obtained in step S2 of FIG. 2 is X = 0.75. At this time, if the cumulative car allocation values of the first floor and each floor of the B floor for the past 5 minutes were 16 times (the cumulative allocation value of the first floor) and 21 times (the cumulative allocation value of the B floor), the above second The allocation ratio Y = (16 + 1) /21Δ0.81 obtained in step S3 in the figure, and the allocation ratio Z = 16 / (21 + 1) Δ0.73 obtained in step S4. Therefore, the absolute value M = | 0.75-0.81 | = 0.06 obtained in step S5 and the absolute value N = | 0.75-0.73 | = 0.02 obtained in step S6. As a result, 0.06> 0.02 (that is, M> N), and step S9 is selected in the determination of step S7, and B
A car is assigned to a floor ascending call. That is,
The allocation arithmetic unit 1 outputs a B floor hall uplink call allocation signal BUW to a drive control device (not shown) of the elevator. Upon receiving this allocation command, the car that has finished the service on each upper floor directly responds to the hall upcoming call on the B floor. Also,
With this allocation, the cumulative car allocation on the B floor is updated.
(= 21 + 1) times, and this data is stored in the main storage device 3 of the allocation processing device 1.

Then, as in the above, the passenger load ratio (traffic ratio) on the first floor and the B floor remains 3: 4 (that is, the passenger load ratio X = 0.75 obtained in step S2 remains), and the elevator car allocation operation is performed. If continued, the cumulative car allocations for each floor of the 1st floor and B floor for the past 5 minutes will be 16 times (cumulative value of 1st floor) and 22 times (cumulative value of B floor allocation). The allocation ratio Y obtained in S3 is Y = (16 + 1) /22Δ0.77, and the allocation ratio Z obtained in step S4 is Z = 16 / (22 + 1) Δ0.70. Therefore, the absolute value M = | 0.75-0.77 | = 0.02 obtained in step S5, and the absolute value N = | 0.75-0.70 | = 0.05 obtained in step S6. As a result, 0.02 <0.05 (that is, M <N), and this time, step S8 is selected in the determination of step S7, and the car is assigned to the hall upcall on the first floor.
That is, from the allocation arithmetic unit 1, the first floor hall uplink call allocation signal 1UW
Is output to the drive control device (not shown) of the elevator. Upon receiving this allocation command, the car that has finished the service on each floor above responds directly to the landing call on the first floor.
Further, this time, the total value of the first floor car allocation is updated to 17 = (16 + 1) times by this allocation, and this data is stored in the main storage device 3 of the allocation arithmetic unit 1.
