In the waiting area 40 or the waiting area 50 of a specific floor, the destination floor registration unit 102 operates the landing operation panel 42 of the user to provide destination direction information about the destination floor (specifically, whether to ascend or descend). If is registered (step S11: Yes), the process proceeds to step S12, and if it is not registered (step S11: No), it waits until the landing operation panel 42 is operated.

<Step S12>
The allocation unit 104 is the optimum elevator unit for boarding the user based on the destination direction information of the user registered by the destination floor registration unit 102, the operation information acquired by the operation status monitoring unit 101, and the like. To assign. In this case, when the user operates the landing operation panel 42 in the standby area 40, the allocation unit 104 is one or more lower floor elevators 11 of the lower floor bank 10 and one or more of the two-way bank 30. The most suitable elevator unit is assigned from the two-way elevators 31. Further, when the user operates the landing operation panel 42 in the standby area 50, the allocation unit 104 has one or more high-rise elevators 21 in the high-rise bank 20 and one or more two in the two-way bank 30. The most suitable elevator unit is assigned from the directional elevators 31. Then, the process proceeds to step S13.

<Step S13>
Next, the allocation notification unit 106 notifies the landing guidance unit 105 of the elevator unit assigned by the allocation unit 104, and transmits the elevator unit to the elevator control devices 210, 220, 230 via the communication unit 121. Notice. Then, the process proceeds to step S14.

<Steps S91-S94>
The processes of steps S91 to S94 are the same as the processes of steps S71 to S74 shown in FIG. 12, respectively.

<Step S95>
If there is another elevator (other car) that opens at the same timing in the same waiting area (waiting area 40 or waiting area 50) (first waiting place), the process proceeds to step S96. If there is no other elevator (step S95: No), the process proceeds to step S110. Regarding this, for example, whether or not there is another elevator (another car) that opens at the same timing in the same standby area by the operation status monitoring unit 101 (an example of the first confirmation unit), that is, It may be confirmed whether or not there is another elevator that is scheduled to stop on the floor of the waiting area where the user waits and open the door on the waiting area side.

<Step S96>
When the unit of the two-way elevator 31 is assigned by the allocation unit 104 (step S96: Yes), the process proceeds to step S97, and an elevator other than the two-way elevator 31 (lower floor elevator 11 or higher floor elevator 21) is assigned. In the case (step S96: No), the process proceeds to step S111.

<Step S97>
When another user is waiting in the waiting area on the opposite side (for example, the waiting area 50 when the user operates the landing operation panel 42 in the waiting area 40) (second waiting place) (step S97: Yes), the process proceeds to step S98. On the other hand, when another user is not waiting in the standby area on the opposite side (step S97: No), the process proceeds to step S111. This can be determined by detecting whether or not the landing operation panel 42 has been operated in the standby area on the opposite side by the destination floor registration unit 102 (an example of the second confirmation unit). Alternatively, it may be determined based on the congestion status of the standby area 40 or the standby area 50 estimated by the congestion estimation unit 103 (an example of the second confirmation unit).

<Step S98>
When there are other elevators that open at the same timing in the same standby area, the unit of the two-way elevator 31 is assigned by the allocation unit 104, and another user is waiting in the opposite standby area. The in-car confirmation unit 108 confirms whether or not there is a user (passenger) in the car of the two-way elevator 31 of the unit assigned to the allocation unit 104. If there is a user (passenger) in the car of the two-way elevator 31 (step S98: Yes), the process proceeds to step S99, and if not (step S98: No), the process proceeds to step S108.

<Step S99>
When the car confirmation unit 108 confirms in step S98 that there is a user (passenger) in the car of the two-way elevator 31 of the unit assigned to the allocation unit 104, the same timing in the same standby area Check if there are any users (passengers) in the car of other elevators that open the door. If there is a user (passenger) in the car of another elevator (step S99: Yes), the process proceeds to step S100, and if not (step S99: No), the process proceeds to step S102.

<Step S100>
The boarding time measuring unit 111 measures the boarding time of each user of the two-way elevator 31 of the unit assigned to the allocation unit 104 and other elevators that open at the same timing in the same standby area. If the boarding time of the user of the two-way elevator 31 is longer than the boarding time of the user of another elevator (step S100: Yes), the process proceeds to step S101, and if it is shorter (step S100: No), the step. Move to S109.

<Step S101>
When the boarding time of the user of the two-way elevator 31 of the unit assigned by the allocation unit 104 measured by the boarding time measuring unit 111 is longer than the boarding time of the user of another elevator, the door opening direction command is given. The unit 107 determines that the door (door 31a or door 31b) on the standby area side opposite to the user's standby area is opened for the two-way elevator 31. Then, the priority determination unit 110 determines to preferentially open the door of the two-way elevator 31 on which the user is riding. Then, the process proceeds to step S102.

<Step S102>
The door opening direction notification unit 109 notifies the user riding in the two-way elevator 31 of the door opening direction of the two-way elevator 31 determined by the door opening direction command unit 107. Then, the process proceeds to step S103.

<Step S103>
Then, the door opening direction command unit 107 refers to the door (door 31a or door 31b) on the standby area side opposite to the user's standby area with respect to the two-way elevator 31 of the unit assigned by the allocation unit 104. Is instructed to the elevator control device 230 via the communication unit 121 to open the door. Then, the process proceeds to step S104.

<Step S104>
The occupancy rate confirmation unit 112 gets on the two-way elevator 31 of the unit assigned by the allocation unit 104 after another user gets on the two-way elevator 31 after the command by the door opening direction command unit 107 in step S107. Check if the occupancy rate of the passengers is below the standard value. When the occupancy rate of the two-way elevator 31 is equal to or less than the reference value (step S104: Yes), the process proceeds to step S105, and when the reference value is exceeded (step S104: No), the process proceeds to step S107.

<Step S105>
When the user is waiting in the waiting area where the two-way elevator 31 of the unit assigned by the allocation unit 104 was originally scheduled to open (step S105: Yes), the process proceeds to step S106. In this case, for example, when there is another elevator that opens at the same timing in the same standby area in step S95, the passenger guided by the landing guide 105 in step S94 boarded the other elevator. Later, it is assumed that a new user is waiting in the waiting area. In addition, it is naturally assumed that the original user who missed the opportunity to board the other elevator is waiting in the waiting area as it is. On the other hand, when the user is not waiting in the standby area (step S105: No), the process proceeds to step S107. This can be determined by detecting whether or not the landing operation panel 42 has been operated in the standby area. Alternatively, it may be determined based on the congestion status of the standby area 40 or the standby area 50 estimated by the congestion estimation unit 103.

<Step S106>
Then, the door opening direction command unit 107 refers to the door (door 31a or door 31b) on the waiting area side of the user who was originally scheduled to open the door with respect to the two-way elevator 31 of the unit assigned by the allocation unit 104. Is instructed to the elevator control device 230 via the communication unit 121 to open the door. Then, the process proceeds to step S107.

<Step S107>
After the user is placed in the car, the elevator that opens the door operates according to the destination floor designated by the operation panel 12 in the car.

<Step S108>
When the vehicle interior confirmation unit 108 confirms in step S98 that there are no users (passengers) in the vehicle of the two-way elevator 31 of the unit assigned to the allocation unit 104, the same standby area (standby area 40). Alternatively, it is confirmed whether or not there is a user (passenger) in the car of another elevator that opens at the same timing in the waiting area 50). If there is a user (passenger) in the car of another elevator (step S108: Yes), the process proceeds to step S109, and if not (step S108: No), the process proceeds to step S111.

<Step S109>
Then, the priority determination unit 110 determines to preferentially open the door of the other elevator on which the user is riding. Then, the process proceeds to step S113.

<Steps S110, S111>
The processing of steps S110 and S111 is the same as the processing of steps S87 and S88 shown in FIG. 12, respectively.

As described above, in the elevator system 1 according to the present embodiment, there is another elevator that opens at the same timing in the same standby area, the unit of the two-way elevator 31 is assigned by the allocation unit 104, and the opposite side. When another user is waiting in the waiting area of, the two-way elevator 31 controls the door opening direction and the occupancy rate confirmation unit so that multiple elevators do not open at the same timing in the same waiting area. When it is confirmed by 112 that the occupancy rate of the passengers on the two-way elevator 31 of the unit assigned by the allocation unit 104 is less than the reference value, the user who was originally scheduled to open the door The door on the waiting area side will be opened to allow passengers to board. As a result, the same effect as that of the fourth embodiment can be obtained, and the operation of the elevator can be further made more efficient.
