FIG. 3 is a front view showing a 7th floor hall by the elevator group management control device according to the first embodiment of the present invention. The operation of this embodiment will be described with reference to FIGS.

It should be noted that here, events such as meetings are completed on the 7th floor, and one elevator car departs with a load above a predetermined level,
Under the situation that the elevator hall on the 7th floor is still full of waiting passengers, the hall destination button 12 has the 1st floor, 3rd floor, and 4th floor.
Described below is the case where the call for the floor is registered.

When the program of FIG. 2 is executed, it is determined in step S1 that there is an elevator car that departs from the 7th floor hall with a load of a predetermined value or more, and in step S2 a plurality of 7th floor halls are assigned as congested floors and a plurality of cars are allocated. Get ready. First,
In step S3, the concentrated floor input from the outside is inquired.
Then, in step S4, it is determined whether or not the registered destination floor of the 7th floor hall has the floor. For example, if the input data from the outside indicates the first floor, there is the first floor among the registered destination floors of the first, third, and fourth floors of the seventh floor hall, so the process proceeds to step S5, and the seventh floor One elevator car is allocated to the destination floors other than the first floor, and the elevator car is additionally allocated to the destination call to the first floor on the seventh floor in step S6. That is, one elevator car is assigned to each of the 3rd, 4th floor and the 1st floor, and the destination floors are displayed like the hall destination floor indicators 18A and 18B in FIG. Then, in step S9, the series of operations described above is performed for all elevator halls, and this routine is finished. In this way, by dividing the destination floor of waiting passengers overflowing on the 7th floor hall,
Even if Unit A arrives early at the 7th floor landing and passengers riding on Unit B wait a little longer at the 7th floor landing, the arrival time to the 1st floor will be earlier, so the service completion time will be shorter.

As described above, the elevator group supervisory control system according to the present embodiment has three elevator cars A to C 16A to 16C.
16Cs are installed at each floor of elevators that are installed side by side,

There is provided a destination floor specifying means such as step S6 in FIG. 2 for specifying the destination floor of the car by using the input means 19 based on predetermined data input from the outside as in step S3 in FIG.

That is, the elevator group supervisory control apparatus of the present embodiment selects the optimum car from a plurality of elevator cars and assigns it to the call registration for registering each call corresponding to the destination floor. The degree of congestion is detected according to the number of passengers in the car, and a plurality of elevator cars are additionally allocated to the floor of the floor according to the detection result, and the destination floor of this additional allocated car is specified based on predetermined data input from the outside. It is a thing.

Therefore, by allocating another elevator car to the destination floor where the concentration of waiting customers registered from the outside is predicted in advance, the dumpling operation can be eliminated and the service completion time can be shortened. In other words, the congestion level of the elevator hall is detected, and the destination floor of the second vehicle to be assigned is limited to the floor where the number of passengers expected to get off at that time is the highest, so the service of many passengers is completed. Time can be shortened and comfortable service can be provided. As a result, the rotation efficiency of the elevator car is increased, and the transportation efficiency of the entire building is improved. Particularly, in the present embodiment, it is not necessary for each waiting customer to press the destination floor button, and a special counter for each floor is not required, so that the hardware configuration is inexpensive.

<Second Embodiment> In the first embodiment, the case where the concentrated floor is input from the outside has been described, but in the present embodiment, the case where the floor is not input from the outside will be described. Since FIG. 1 is common to this embodiment, the description thereof is omitted here.

When the centralized floor is not input from the outside, step S3 is deleted in the flowchart of FIG. 2, and in the determination of step S4, the centralized floor input from the outside into the registered destination floor of the 7th floor hall. Since it is determined that there is not, the process proceeds to step S7, and the past learning data is viewed. That is, the learning data obtained by accumulating past exit loads for each floor is read. This learning data is shown in Figure 4.
(A) of FIG. FIG. 4 (a) is an explanatory diagram showing learning data of the exit load of the elevator group management control device according to the second embodiment of the present invention, in which cumulative values of exit loads for the past several minutes are taken for each floor. Is.

Now, assuming that the learning data is as shown in FIG. 4A, in step S8, the first floor is selected as the largest floor among the data of the first, third, and fourth floors, and S = 1 floor. Become. After this, the flow is the same as in the first embodiment. That is, one elevator car is assigned to the destination floors other than the first floor of the seventh floor in step S5, and an additional elevator car is assigned to the destination call to the first floor of the seventh floor in step S6. As in the floor indicators 18A and 18B, the destination floor is divided into the first floor, the third floor, and the fourth floor for display. And
This routine ends when it is determined in step S9 that the above-described series of operations have been performed for all elevator halls. In this way, even if the command for the centralized floor is not given from the outside, as in the first embodiment, by separating the destination floors of the waiting passengers overflowing in the 7th floor hall, the passengers can quickly get to the 7th floor hall. Even if the passengers arriving and boarding Unit B wait a little longer at the 7th floor hall, the arrival time to the 1st floor will be earlier, so the service completion time will be shorter.

In this way, the elevator group supervisory control system of this embodiment has the same landing destination button 12 as that of the first embodiment.
2 and the call registration means including the landing destination button registration means 13, the group management means 11, the in-car load detectors 17A to 17C and the pedestal management means 14A to 14C, and the congestion detection means performing the operation of step S1 in FIG. In addition to the additional allocating means as in step S5 of step S5, using the learning data as shown in FIG. A destination floor specifying means such as step S8 in FIG. 2 for specifying the floor with priority is provided.

That is, the elevator group management control device of the present embodiment preferentially specifies the destination floor of the additionally assigned car by using the learning data obtained by accumulating the number of people who have exited in the past for each floor. It is a thing. Therefore, also in this embodiment, by eliminating the dumpling operation by assigning an elevator car to the destination floor where it is predicted that many passengers will get off,
Service completion time can be shortened. In other words, the congestion level of the elevator hall is detected, and the destination floor of the second vehicle to be assigned is limited to the floor where the number of passengers expected to get off at that time is the highest, so the service of many passengers is completed. Time can be shortened and comfortable service can be provided. As a result, the rotation efficiency of the elevator car is increased, and the transportation efficiency of the entire building is improved. In particular, in the present embodiment, it is not necessary for each waiting customer to press the destination floor button, and a special counter for each floor is not required, so the hardware configuration becomes inexpensive.

<Third Embodiment> In the second embodiment, when there is no accumulation of data in the past several hours in a very quiet state, or when the respective values are equal in each floor, there is a sudden floor. When the car is crowded, the destination floor of the additional allocated car cannot be properly divided.

Therefore, in the third embodiment, it is checked which floor the elevator car that started from the seventh floor with a load of a predetermined value or more stops, and what percentage of the load in the car gets off at which floor. As in the second embodiment, the floor where the load inside the car is reduced most is divided and the other elevator cars are assigned. This will be described with reference to FIG. FIG. 4B is an explanatory diagram showing learning data of the getting-off load of the elevator group management control device according to the third embodiment of the present invention. Since FIG. 1 is common to this embodiment, the description thereof is omitted here.

In FIG. 4 (b), an elevator car leaving the 7th floor with a load of 80% unloads 30% of passengers on the 3rd floor, 10% of passengers on the 2nd floor, and 40% of passengers on the 1st floor. It is shown that. This is the step S7 in the flowchart of FIG.
In the same way as in the above-mentioned operation, if the read is performed and the maximum floor is S, then in the case of the present embodiment, S = 1 floor as in the second embodiment. After this, the flow is the same as in each of the above embodiments. That is, one elevator car is assigned to the destination floors other than the first floor of the seventh floor in step S5, and an additional elevator car is assigned to the destination call to the first floor of the seventh floor in step S6. The display is made like the floor indicators 18A and 18B. Then, the series of operations described above is performed for all elevator halls, and this routine is finished. In this way, even when the command for the concentrated floor is not given from the outside, as in each of the above-described embodiments, the destination floors of the waiting passengers overflowing in the 7th floor hall are divided and placed, so that the arrival of Unit A at the 7th floor hall early. However, even if passengers of Unit B wait a little longer at the 7th floor hall, the arrival time to the 1st floor will be earlier, so the service completion time will be shorter.

As described above, the elevator group management control device of this embodiment is provided with the call registration means, the group management means 11 and the inside of the car, which are composed of the landing destination buttons 12 and the landing destination button registration means 13 similar to those in the above embodiments.

As shown in FIG. 4 (b), priority is given to the floor with the highest exit load among the floors on which the elevator car that has departed upon detection of congestion has stopped and the destination floor is identified as in step S8 in FIG. Equipped with means.

That is, the elevator group management control device of the present embodiment gives priority to the floor of the highest loading load among the floors where the elevator car that has departed after detecting the congestion at the destination floor of the additionally allocated car. To identify. Therefore, in this embodiment as well, by assigning an elevator car to a destination floor where it is predicted that many passengers will get off, dumpling operation can be eliminated and service completion time can be shortened. In other words, the congestion level of the elevator hall is detected, and the destination floor of the second vehicle to be assigned is limited to the floor where the number of passengers expected to get off at that time is the highest, so the service of many passengers is completed. Time can be shortened and comfortable service can be provided. As a result, the rotation efficiency of the elevator car is increased, and the transportation efficiency of the entire building is improved. In particular, in the present embodiment, it is not necessary for each waiting customer to press the destination floor button, and a special counter for each floor is not required, so the hardware configuration becomes inexpensive.

<Fourth Embodiment> In the first to third embodiments, the passengers in the descending direction have been described by taking the seventh floor hall as an example, but the situation is different in the first floor hall. That is, it is preferable to assign the destination floors by appropriately combining the first to third embodiments according to the start time of the event on the destination floor and the like. Since FIG. 1 is common to this embodiment, the description thereof is omitted here.

For example, in the morning work hours, the destination floor is divided according to the past learning data. In addition, at lunch time and in the time when the event in the evening starts, the destination floor is divided according to the floor where the elevator car in front of the car has a lot of getting off the load, and in other normal hours, the destination floor is determined by the external input data floor. If there is no input data, it is effective to divide the destination floor according to past learning data.

Thus, in addition to the call registration means, group management means, congestion detection means, and additional allocation means similar to those in the above-described respective embodiments, the elevator group management control device of this embodiment has the destination floor of the additionally allocated car. It is equipped with a destination floor specifying means for selecting and specifying according to the time of day.

That is, the elevator group supervisory control system of this embodiment selects and specifies the destination floor of the additional assigned car according to the time zone of the day. Therefore, by assigning an elevator car to the destination floor in consideration of the time zone, the dumpling operation can be canceled and the service completion time can be shortened. In other words, by detecting the congestion level of the elevator hall,
Since the destination floor of the machine to be assigned to the second car is limited to the floor where the number of passengers expected to get off at that time is the largest, the service completion time for many passengers can be shortened and a comfortable service can be provided. As a result, the rotation efficiency of the elevator car is increased, and the transportation efficiency of the entire building is improved. Also in this embodiment, since it is not necessary for each waiting customer to press the destination floor button and a special counter for each floor is not required, the hardware configuration becomes inexpensive.

By the way, in each of the above-mentioned embodiments, as a method for detecting a congested floor, the elevator car was started with a high load as an example. The same effect can be obtained even if the crowded floor is detected by using it. Further, in each of the above embodiments,
Although the allocation for the first floor was limited to Unit B, it is possible to easily allocate it to Unit A.
