(Configuration of ventilation control unit)
The ventilation control unit 12 controls the ventilation of the car 21 and performs open ventilation of the car 21. Further, the ventilation control unit 12 controls the ventilation of the car 21 on the floor where open ventilation of the car 21 is scheduled, based on the landing detection information including information regarding the presence or absence of people within the predetermined range R1 in the landing 70 of the car 21. Control open ventilation.

Thereby, on the floor where open ventilation of the car 21 is scheduled to be performed, open ventilation is controlled by the hall detection information. Therefore, it is possible to control the open ventilation according to the presence or absence of people within the predetermined range R1 at the landing 70 of the car 21, and the open ventilation of the car 21 can be performed without causing discomfort to the people in the landing. be able to.

Here, ventilation and open ventilation during operation of the car 21 will be explained. During operation, the car 21 is ventilated by supplying air from inside the tower T1 into the car 21 with the door 22 closed using the fan 41. Surplus air in the tower T1 supplied into the car 21 is discharged from the gap in the car 21 to the tower T1.

On the other hand, in open ventilation, as described above, the car 21 is stopped at a floor with a landing 70, the door 22 of the car 21 is opened, and the car 21 is moved to the landing 70 of the car 21 on the stopped floor. This is done by expelling the air inside. Since open ventilation is performed by opening the door 22 in this way, the air in the tower T1 that has been supplied into the car 21 is discharged from the opened door 22. Therefore, even when the air in the tower T1 is supplied into the car 21 during operation, stronger ventilation can be achieved by doing so with the door 22 of the car 21 open at the landing 70. This makes it possible to function as open ventilation. The ventilation amount for open ventilation can be set as appropriate, and may be the same as the ventilation amount for ventilation during operation, or may be greater than the ventilation amount.

In this way, open ventilation of the car 21 is performed by opening the door 22 of the car 21 and discharging the air inside the car 21, so that the wind caused by the exhaust of air from the car 21 toward the landing 70 is carried out. arise. On the other hand, as described above, open ventilation is controlled depending on the presence or absence of people within the predetermined range R1 in the landing 70, so it is possible to suppress situations in which people are exposed to wind.

The ventilation control section 12 includes a start determination section 121 , a ventilation floor determination section 122 , an open ventilation control section 123 , and an end determination section 124 .

The start determination unit 121 determines whether or not to start open ventilation for the car 21 based on the operation information of the car 21 acquired by the information acquisition unit 11. The start determination unit 121 determines to start open ventilation of the car 21 when a predetermined start condition is satisfied. Examples of start conditions include (1) the car 21 has not been used for a certain period of time, (2) the pre-scheduled time has arrived, and (3) after all users have exited the car 21. Another example is that other users are not registered to call. Note that open ventilation may be implemented when all of a plurality of starting conditions are met, or open ventilation may be implemented when a predetermined combination of starting conditions is met.

When the start determining unit 121 determines to start open ventilation, the ventilation floor determining unit 122 determines the floor on which open ventilation will be performed. The floor on which open ventilation is performed can be set arbitrarily, and may be, for example, the floor closest to the car 21 when the start determination unit 121 determines open ventilation, or a predetermined floor.

The open ventilation control unit 123 determines, based on the hall detection information acquired by the information acquisition unit 11, whether there is a person within a predetermined range R1 on the floor where open ventilation of the car is scheduled to be performed, which is determined by the ventilation floor determination unit 122. Determine whether If there is no person within the predetermined range R1, the open ventilation control unit 123 starts open ventilation at the floor determined by the ventilation floor determination unit 122.

The open ventilation control unit 123 stops the start of open ventilation when it is detected that there is a person within a predetermined range R1 on the floor where open ventilation of the car is scheduled based on the landing detection information, or The air inside the car 21 is discharged into the tower interior T1 of the car 21.

Further, the open ventilation control unit 123 stops the start of open ventilation if it is detected that there is a person within the predetermined range R1 on the floor where open ventilation of the car is being performed, based on the landing detection information. Alternatively, the air inside the car 21 is discharged into the tower interior T1 of the car 21.

When stopping open ventilation, the open ventilation control unit 123 stops the open ventilation by, for example, closing the door 22 or stopping the fan 41. In addition, the open ventilation control unit 123 rotates the fan 41 in the opposite direction or operates a fan that exhausts the air inside the car 21 into the tower T1, so that the air inside the car 21 is transferred to the tower of the car 21. It is discharged to inner T1.

As a result, if it is detected that there is a person within the predetermined range R1 of the landing 70, open ventilation is stopped or the air inside the car 21 is discharged into the tower T1 of the car 21. , wind from the car 21 due to open ventilation of the car 21 does not flow to the landing 70. Therefore, it is possible to prevent people in the hall 70 from feeling uncomfortable.

The end determination unit 124 determines whether or not open ventilation for the car 21 is to be ended. The end determination unit 124 determines the end of open ventilation of the car 21 when a predetermined end condition is satisfied. Examples of termination conditions include (1) the car 21 has performed open ventilation for a certain period of time or more, and (2) a call has been registered by the user. Note that open ventilation may be terminated when all of a plurality of termination conditions are satisfied, or may be terminated when a predetermined combination of termination conditions is satisfied. The end determination unit 124 ends open ventilation by, for example, closing the door 22.

The notification control unit 13 controls the notification unit 51 and notifies people in the landing 70 of the car 21 that open ventilation will be implemented. In this embodiment, the notification unit 51 is a projector that displays an image on the hall 70, and the notification control unit 13 controls the display content of the projector.

FIG. 5 is a plan view showing an example of notification of the elevator ventilation control device. As shown in 5001 in FIG. 5, for example, during open ventilation, the notification control unit 13 projects an area indicating a predetermined range R1 onto the floor surface using the notification unit 51, and displays an image G including a message "ventilating". May be displayed. As a result, it is possible to notify people in the hall that open ventilation is being implemented for the car 21, and it is possible to prevent people from entering the predetermined range R1, so that the wind from the open ventilation can You can guide it so that it doesn't hit you.

In addition, when a person enters the predetermined range R1, as shown in 5002 in FIG. Image G may be changed to include a message such as "Press the destination floor button and you can board the train." This allows users to be informed that the elevator 20 is available for use even during open ventilation, allowing users to be prioritized over open ventilation and preventing loss of convenience for users. It can be prevented.

In this embodiment, the notification section 51 is provided in the transom inside the car 21. The notification unit 51 may be installed not only in the car 21 but also in the landing 70. By installing the notification unit 51 inside the car 21, there is no need to install the notification unit 51 on each floor, so installation costs can be reduced.

The location where the notification unit 51 makes the notification is not limited to the floor of the landing 70. The notification may be displayed on an existing display installed around the car 21, or may be notified by voice. Further, for example, if a person comes within the predetermined range R1, a notification may be provided by display and audio.
