Determine the door opening time.
The door opening time is determined as a longer time as the number of passengers increases, and is determined as a shorter time as the number of passengers decreases.
For example, the door opening time per person is predetermined, and the total time for the number of passengers is determined as the door opening time. If the door opening time per person is “a second / person” and the number of passengers is 7, the door opening time is determined as “7 × a” seconds. An upper limit value and a lower limit value may be set for the door opening time.
Further, for example, a table in which the number of passengers and the door opening time are associated may be used to determine the door opening time, or a function that uses the number of passengers as an input value and the door opening time as an output value. An equation may be used. Tables and function formulas used for determining the door opening time are defined in advance and stored in the memory.
After S122, the process proceeds to S131.

<S131>
The elevator control unit 3 determines whether the elevator car 1 has arrived at the destination floor.
If it is determined that the elevator car 1 has arrived at the destination floor (YES), the process proceeds to S132.
When it is determined that the elevator car 1 has not arrived at the destination floor (NO), the process of the door opening control method shown in FIG. 2 is finished, and when a predetermined time has elapsed, the process starts again from the first process (S111). Executed.

When it is determined that the elevator car 1 is being opened (YES), the process proceeds to S134.
If it is determined that the elevator car 1 has not started to open and is not open (NO), the process proceeds to S133.

<S133>
When it is determined in S132 that the elevator car 1 is not open (NO), the elevator controller 3 outputs the door control signal 3b to the elevator car 1 based on the door opening time determined in S122, and the elevator car 1 Let 1 start door opening. The elevator car 1 that has received the door control signal 3b opens for the door opening time determined in S122 and closes when the door opening time has elapsed. The door opening time may mean a time including an opening / closing time indicating a time required for the door to be fully opened and a time required for the door to be closed from the fully open state. Except for this, it may mean the time in the fully open state.
After S133, the process proceeds to S134.

<S134>
The elevator control unit 3 determines whether the elevator car 1 that has started to open has been opened and closed.
When it is determined that the elevator car 1 is closed (YES), the elevator control unit 3 newly determines a destination floor based on the unprocessed landing destination call 2a generated until the elevator car 1 is closed, The elevator car 1 is driven toward the newly determined destination floor.
When it is determined that the elevator car 1 is closed (YES), the process proceeds to S135.
When it is determined that the elevator car 1 is not closed (NO), the process of the door opening control method shown in FIG. 2 is finished, and is executed again from the first process (S111) when a predetermined time has elapsed. The

Is provided.
The personal authentication device 9 (an example of a user management device) includes a CPU and a memory, and an ID for identifying each user permitted to use the elevator is stored in the memory in advance. Hereinafter, an ID stored in advance in the memory is referred to as a registered ID. Furthermore, each registration ID is associated with an attribute of a user (hereinafter referred to as a registrant) identified by the registration ID and information indicating a floor (hereinafter referred to as a residence floor) where the registrant lives. (An example of user information). Types such as general persons, wheelchair users, elderly people, and children are examples of registrant attributes.
The personal authentication device 9 (an example of a landing device and an identification information input device) inputs the ID of a person who intends to use the elevator. For example, the personal authentication device 9 includes a non-contact IC card reader. A person who wants to use the elevator does not press the call button as in the second embodiment, but uses an IC card (hereinafter referred to as an ID card) in which his / her ID is recorded as a non-contact IC of the personal authentication device 9. Move closer to the card reader. By bringing the ID card closer to the non-contact IC card reader of the personal authentication device 9, a person who wants to use the elevator requests registration of a landing destination call with his / her residence floor as the destination floor. Then, the non-contact IC card reader of the personal authentication device 9 wirelessly communicates with the approached ID card, acquires the ID recorded on the ID card, and uses the acquired ID as the input ID.

The personal authentication device 9 executes a personal authentication process for authenticating the user based on the input ID using the CPU. In the personal authentication process, the personal authentication device 9 searches the memory and determines whether there is a registration ID that matches the input ID.
If there is a registration ID that matches the input ID, the personal authentication device 9 determines that the authentication is OK and accepts a request for registration of the destination call. When accepting a request for registration of a destination call, the personal authentication device 9 uses the attribute (ID input of the registrant) associated with the registration ID corresponding to the call generation floor (own floor) and the input ID. And the data including the information indicating the residence floor of the registrant associated with the registration ID (the residence floor of the user who has input the ID) is output to the elevator control device 22 as authentication information 9a. . The residence floor of the registrant included in the authentication information 9a is the destination floor of the elevator car 1.
If there is no registration ID that matches the input ID, the personal authentication device 9 determines that the authentication is NG and does not accept the request for registration of the destination call. For example, the personal authentication device 9 sounds a buzzer to notify the user that the destination call registration request is not accepted for authentication NG.

The elevator control device 22 includes a landing destination call registration unit 8 in addition to the configuration described in the second embodiment (see FIG. 3).
The landing destination call registration unit 8 uses the CPU to input the authentication information 9a output from the personal authentication device 9, and uses the input authentication information 9a as the landing destination call 8a to the elevator control unit 3 and the personal attribute identification unit 7. Output. The landing destination call 8a corresponds to the landing destination call 2a described in the second embodiment.

The elevator control device 22 includes a personal attribute specifying unit 7 (an example of a passenger attribute specifying unit) instead of the call attribute specifying unit 6 with respect to the configuration described in the second embodiment (see FIG. 3).
The personal attribute specifying unit 7 (an example of the passenger attribute specifying unit) uses the CPU to input the landing destination call 8a output from the landing destination call registration unit 8, and based on the input landing destination call 8a, the user ( Identify the attributes of passengers.

If it is determined in S311 that the authentication information 9a is input (YES), the landing destination call registration unit 8 outputs the authentication information 9a as the landing destination call 8a to the elevator control unit 3 and the personal attribute specifying unit 7.
After S312, the process proceeds to S321.

<S321>
The personal attribute specifying unit 7 inputs the landing destination call 8a from the landing destination call registration unit 8, and determines whether the user is a wheelchair user based on the attribute of the user indicated by the input landing destination call 8a.
If it is determined that the user is a wheelchair user (YES), the process proceeds to S333. If it is determined that the user is not a wheelchair user (NO), the process proceeds to S322.

<S322>
When it determines with a user not being a wheelchair user in S321 (NO), the personal attribute specific | specification part 7 determines whether a user is an elderly person based on the attribute of the user which the landing destination call 8a shows.
When it is determined that the user is an elderly person (YES), the process proceeds to S332, and when it is determined that the user is not an elderly person (NO), the process proceeds to S331.

<S331>
When it is determined in S322 that the user is not an elderly person (NO), since the user is a general person who is neither a wheelchair user nor an elderly person, the passenger number specifying unit 4 is the same as S112 described in the first embodiment. , “1” is set in “Number of occurrences”.

<S332>
When it is determined in S322 that the user is an elderly person (YES), the passenger number identification unit 4 sets “1.5” in “Number of occurrences”.
Older people take longer to get on and off the elevator car 1 than ordinary people (younger people). Therefore, the passenger number specifying unit 4 converts the time required for one elderly person to get into and out of the elevator car 1 to 1.5 people, and the “number of people generated” is not “1” but “1.5”. "Is set. However, the passenger number specifying unit 4 may set “number of occurrences” other than “1.5” (such as “1.2”, “2”, “2.5”, etc.).
After S332, the process proceeds to S334.

<S333>
When it is determined in S321 that the user is a wheelchair user (YES), the passenger number specifying unit 4 sets “2” in “Number of occurrences”.
Wheelchair users take longer to get on and off the elevator car 1 than ordinary people. Therefore, the passenger number specifying unit 4 converts the time required for one wheelchair user to get into and out of the elevator car 1 to two ordinary people, and sets “2” instead of “1” as the “occurrence number”. Set. However, the passenger number specifying unit 4 may set other than “2” (“1.2”, “1.5”, “2.5”, etc.) to the “occurrence number”.
After S333, the process proceeds to S334.

<S334>
As in S113 described in the first embodiment, the number of passengers identification unit 4 generates the number of passengers at the call generation floor indicated by the landing destination call 8a and the number of passengers at the destination floor indicated by the landing destination call 8a. Is added.
After S334, the process proceeds to S341.

<S341 to S355>
Thereafter, S341 to S355 are executed in the same manner as S121 to S135 described in the first embodiment.
That is, when the elevator car 1 arrives at the destination floor (S341), the door opening time determination unit 5 determines the door opening time of the elevator car 1 based on the number of passengers on the destination floor (S342). Next, when the elevator car 1 arrives at the destination floor (S351) and the door opening is not started (S352), the elevator control unit 3 causes the elevator car 1 to start the door opening (S353). When the determined door opening time elapses and the elevator car 1 is closed (S354), the passenger number identification unit 4 clears the number of passengers on the old destination floor (S355).

  Even if the boarding / alighting time varies depending on the user, the door opening time of the elevator car 1 is controlled according to the traffic volume (the number of passengers in the elevator car 1) by the above-mentioned door opening control method (FIG. 7). Service can be provided.
