- the call registration unit 14 registers a call (a landing call or a landing destination call) based on information from the landing 4.
- the call registration unit 14 registers a call (destination call) based on information from the car 2.
- the call registration unit 14 has a function for limiting who can register calls to authorized users of the elevator. For example, the call registration unit 14 restricts persons who can register a call to the owner of the tag 10. A person who has the tag 10 is regarded as the owner of the tag 10. It may be set in advance so that all owners of the tag 10 can register calls. It may be set in advance so that only a part of the owner of the tag 10 can register a call.
- the function of restricting call registration may be realized by the call registration unit 14 itself, or may be realized using another device.
- the control unit 15 controls the operation of the elevator. For example, when the hall call is registered by the call registration unit 14, the control unit 15 stops the car 2 at the hall 4. When the car 2 stops at the landing 4, the control unit 15 outputs a control signal to the door control device 6. Thereby, the door of the elevator is opened. At this time, the control unit 15 outputs a control signal based on the open width set by the width setting unit 12.
- the door opening width can be appropriately adjusted according to the number of regular users at the landing 4. If the number of authorized users at the hall 4 is large, the door is opened widely, and the convenience is not impaired.

When a call input is made, the input device 16 outputs a call registration request to the control device 1. When the call registration unit 14 receives a call registration request from the input device 16, the call registration unit 14 registers the call based on the received registration request. That is, a general person cannot make a call input to the input device 16.
- Call input is an operation or operation performed by a user to register a call. When a certain state continues, it may be determined that a call input has been performed. Call input is performed using the tag 10. For example, the input device 16 reads the identification information from the tag 10 when the tag 10 is disposed at a very close position. When the input device 16 reads the identification information, it detects that a call input has been performed. The input device 16 may read destination floor information from the tag 10 when reading the identification information from the tag 10.
- the input device 16 may be provided with a direction button (or a destination button). The input device 16 does not detect that a call input has been performed even if the direction button is simply pressed. For example, when the direction button is pressed after reading the identification information from the tag 10, the input device 16 detects that a call input has been performed.
- the width setting unit 12 sets the door opening width based on the number of tags 10 detected by the detection unit 11, for example, as in the case of the first embodiment.
- the width setting unit 12 may set the door opening width based on both the number of tags 10 detected by the detection unit 11 and the presence / absence of a call registered from the landing 4. Information necessary for the width setting unit 12 to set the open width is stored in the storage unit 13.
- Table 2 shows an example of the contents stored in the storage unit 13. Specific values for each item are appropriately set according to the building specifications and the type of elevator.

- the opening width of the door can be set appropriately according to the person actually riding the car 2.
- the input device 16 is not necessarily a device that is required to limit the persons who can register calls to authorized elevator users. Even if the reader 8 is used, the above function can be realized. For example, when the reading device 8 reads the identification information from the tag 10, the reading device 8 outputs its own device information and the read identification information to the control device 1. Further, the reading device 8 detects that the call input has been performed when the same identification information is continuously read for a predetermined time. With this configuration, call input can be performed using the tag 10 without using the input device 16.
- Call input can be performed without using the tag 10.
- an authorized user may use an information storage medium other than the tag 10 to perform call input.

- the reading device 17 When the tag 10 is present in the reading range 18, the reading device 17 reads the identification information of the tag 10 by wireless communication. When reading the identification information from the tag 10, the reading device 17 outputs its own device information and the read identification information to the control device 1.
- the own device information is information for individually identifying the reading device 17.
- the control device 1 can specify the tag 10 from which the reading device 17 has read the identification information by receiving the information from the reading device 17. That is, the control device 1 can specify which tag 10 is in the car 2.
- the detecting unit 11 detects the number of authorized users at the hall 4.
- the detection unit 11 detects the number of authorized users for each hall 4. For example, the detection unit 11 detects the number of tags 10 whose identification information has been read by the reading device 8 as the number of regular users in the hall 4.
- the detection unit 11 performs the above detection at a constant period based on information received from the reading device 8.
- the detection unit 11 detects the number of authorized users in the car 2. For example, the detection unit 11 detects the number of tags 10 whose identification information has been read by the reading device 17 as the number of authorized users in the car 2.

Abstract
Description
特許文献1に記載されたエレベータ装置では、乗場にいる利用者の数を検出する。乗場にいる利用者が少ない場合、利用者がかごに乗る際に、エレベータのドアを全開させない。このような制御は、無駄な電力消費を抑えるために行われる。また、上記制御は、運転効率が低下することを防止するために行われる。
特許文献1に記載されたエレベータ装置では、乗場にいる人が正規利用者か否かを判定することができない。正規利用者ではない人が乗場にいる場合に、エレベータのドアが全開してしまう。
図1はこの発明の実施の形態1におけるエレベータシステムを示す構成図である。図2はこの発明の実施の形態1におけるエレベータシステムの要部を示す構成図である。
制御装置1は、エレベータの運行を制御する。例えば、制御装置1は、駆動装置(図示せず)を制御することにより、かご2を昇降路3内で昇降させる。制御装置1は、エレベータの乗場4の高さに合わせて、かご2を停止させる。
かかる場合、5階の読取装置8により、3つのタグ10から識別情報が読み取られる。読取装置8は、自機情報と読み取った識別情報とを制御装置1に出力する。検出部11は、読取装置8から受信した情報に基づいて、5階の乗場4に存在するタグ10の個数を「3」と検出する。幅設定部12は、検出部11が検出した結果に基づいて、5階での開放幅を75cmと設定する。
図3はこの発明の実施の形態2におけるエレベータシステムを示す構成図である。
本実施の形態では、乗場4に、入力装置16が設けられる。その他の構成は、図1及び図2に示す構成と同じである。
呼び入力は、タグ10を用いて行われる。例えば、入力装置16は、タグ10が極近い位置に配置されると、そのタグ10から識別情報を読み取る。入力装置16は、識別情報を読み取ると、呼び入力が行われたことを検出する。入力装置16は、タグ10から識別情報を読み取る際に、タグ10から行先階の情報を読み取っても良い。
読取装置8を利用しても、上記機能は実現できる。例えば、読取装置8は、タグ10から識別情報を読み取ると、自機情報と読み取った識別情報とを制御装置1に出力する。また、読取装置8は、同じ識別情報の読み取りを一定時間継続して行うと、呼び入力が行われたことを検出する。かかる構成であれば、入力装置16を使用せずにタグ10を用いて呼び入力を行うことができる。
図4はこの発明の実施の形態3におけるエレベータシステムを示す構成図である。
本実施の形態では、かご2に、読取装置17が設けられる。その他の構成は、図1及び図2に示す構成と同じである。
図5はこの発明の実施の形態4におけるエレベータシステムを示す構成図である。
本実施の形態では、乗場4に、入力装置16が設けられる。かご2に、読取装置17及び入力装置19が設けられる。その他の構成は、図1及び図2に示す構成と同じである。
入力装置19は、かご2内で呼びを登録することができる人をエレベータの正規利用者に制限するために、必ずしも必要になる装置ではない。読取装置17を利用すれば、入力装置19を使用せずにかご2内で呼び入力を行うこともできる。呼び入力を行うために、タグ10を用いなくても良い。
I:読取装置8によって識別情報が読み取られたタグ10の個数
II:乗場4から登録された呼びの有無
III:読取装置17によって識別情報が読み取られたタグ10の個数
IV:かご2内の人が乗場4に降りるための行先呼びの有無
I(3):3階の乗場4に設置された読取装置8によって識別情報が読み取られたタグ10の個数
II(3):3階の乗場4から登録された乗場呼びの有無
III(3):3階の乗場4にかご2が停止する時に、読取装置17によって識別情報が読み取られたタグ10の個数
IV(3):かご2内の人が3階の乗場4に降りるための行先呼びの有無
(タグ個数)=α×(乗場のタグ個数)×(乗場呼びの有無)+β×(かごのタグ個数)×(行先呼びの有無) ・・・(1)
α、β:重み付け係数
乗場呼びの有無:「なし」の場合0、「あり」の場合1
行先呼びの有無:「なし」の場合0、「あり」の場合1
表3及び表4に示す内容は、式1において、α=1/2、β=1の場合を示している。重み付け係数α及びβの値は、ビルの仕様やエレベータの種類、設定するセキュリティレベル等に応じて適宜設定される。
V:登録されている行先呼びの個数
かかる場合、記憶部13に、例えば、表6に示す内容が記憶される。
図6はこの発明の実施の形態5におけるエレベータシステムの要部を示す構成図である。制御装置1以外の構成は、実施の形態1乃至4の何れかで開示した構成と同じである。
表9及び表10に示す内容は、上記式1において、α=1/2、β=1の場合を示している。重み付け係数α及びβの値は、ビルの仕様やエレベータの種類、設定するセキュリティレベル等に応じて適宜設定される。
図7はこの発明の実施の形態6におけるエレベータシステムを示す構成図である。
本実施の形態では、かご2に、読取装置17が設けられる。乗場4に、読取装置8は備えられていない。その他の構成は、図1及び図2に示す構成と同じである。
本実施の形態では、正規利用者ではない人がかご2に乗ることを常に厳しく制限する。
時間設定部20は、読取装置17によって識別情報が読み取られたタグ10の個数に基づいて、エレベータのドアの開放時間を設定する。時間設定部20は、かご2内にタグ10が存在しない場合、乗場4にタグ10が存在するか否かに関わらず、ドアの開放時間を一定の値(例えば、最小値)に設定する。かご2内にタグ10が存在しない時にドアの開放時間が最小値に設定される場合、時間設定部20は、かご2内にタグ10が存在する時に、かご2内にタグ10が存在しない時よりもドアが長く開放するようにドアの開放時間を設定する。
