　図１は、実施の形態１に係るエレベーターシステム１の構成図である。 Embodiment 1.
FIG. 1 is a configuration diagram of an elevator system 1 according to the first embodiment.
　エレベーターシステム１は、エレベーター２を備える。エレベーター２は、例えば複数の階床を有する建物に適用される。建物において、エレベーター２の昇降路３が設けられる。昇降路３は、複数の階床にわたる上下方向に長い空間である。昇降路３の下部において、ピット４が設けられる。建物の各々の階床において、昇降路３に隣接する乗場５が設けられる。各々の階床の乗場５において、乗場ドア６が設けられる。乗場ドア６は、昇降路３および乗場５を区画するドアである。エレベーター２は、巻上機７と、主ロープ８と、かご９と、釣合い錘１０と、制御盤１１と、を備える。 The elevator system 1 includes an elevator 2. The elevator 2 is applied, for example, to a building having multiple floors. In a building, a hoistway 3 for an elevator 2 is provided. The hoistway 3 is a vertically long space spanning multiple floors. A pit 4 is provided at the bottom of the hoistway 3. A landing 5 adjacent to the hoistway 3 is provided on each floor of the building. A landing door 6 is provided at the landing 5 of each floor. The landing door 6 is a door that partitions the hoistway 3 and the landing 5. The elevator 2 includes a hoist 7, a main rope 8, a car 9, a counterweight 10, and a control panel 11.
　巻上機７は、例えば昇降路３の上部または下部などに配置される。例えば昇降路３の上方などにエレベーター２の機械室が設けられる場合に、巻上機７は、機械室に配置されてもよい。巻上機７は、モータおよびシーブを備える。巻上機７のモータは、駆動力を発生させる装置である。巻上機７のシーブは、巻上機７のモータが発生させる駆動力によって回転する機器である。 The hoisting machine 7 is arranged, for example, at the upper or lower part of the hoistway 3. For example, when a machine room for the elevator 2 is provided above the hoistway 3, the hoist 7 may be arranged in the machine room. The hoist 7 includes a motor and a sheave. The motor of the hoist 7 is a device that generates driving force. The sheave of the hoisting machine 7 is a device that rotates by the driving force generated by the motor of the hoisting machine 7.
　主ロープ８は、巻上機７のシーブに巻き掛けられる。主ロープ８は、巻上機７のシーブの一方側においてかご９の荷重を支持する。主ロープ８は、巻上機７のシーブの他方側において釣合い錘１０の荷重を支持する。主ロープ８は、巻上機７のシーブの回転によって、巻上機７のシーブのいずれかの側が巻き上げられるように移動する。 The main rope 8 is wound around the sheave of the hoist 7. The main rope 8 supports the load of the car 9 on one side of the sheave of the hoist 7. The main rope 8 supports the load of a counterweight 10 on the other side of the sheave of the hoist 7. The main rope 8 moves as the sheave of the hoist 7 rotates so that either side of the sheave of the hoist 7 is hoisted.
　かご９は、昇降路３を上下方向に走行することでエレベーター２の利用者などを複数の階床の間で輸送する装置である。かご９は、巻上機７のシーブの回転による主ロープ８の移動に連動して昇降路３を上下方向に走行する。かご９は、かごドア１２を備える。かごドア１２は、かご９の内部および外部を区画するドアである。かごドア１２は、かご９がいずれかの階床に停止するときに、当該階床の乗場ドア６を連動させて開閉する機器である。 The car 9 is a device that transports users of the elevator 2 between a plurality of floors by traveling up and down the hoistway 3. The car 9 travels in the vertical direction in the hoistway 3 in conjunction with the movement of the main rope 8 due to the rotation of the sheave of the hoist 7. The car 9 includes a car door 12. The car door 12 is a door that partitions the inside and outside of the car 9. The car door 12 is a device that opens and closes the landing door 6 of the floor in conjunction with the car 9 when the car 9 stops at that floor.
　釣合い錘１０は、巻上機７のシーブの両側にかかる荷重の釣合いをかご９との間でとる装置である。釣合い錘１０は、巻上機７のシーブの回転による主ロープ８の移動に連動して、上下方向においてかご９の反対側に昇降路３を走行する。 The counterweight 10 is a device that balances the load on both sides of the sheave of the hoist 7 with the car 9. The counterweight 10 travels in the hoistway 3 on the opposite side of the car 9 in the vertical direction in conjunction with the movement of the main rope 8 due to the rotation of the sheave of the hoist 7.
　制御盤１１は、エレベーター２の動作を制御する装置である。制御盤１１は、例えば昇降路３の上部または下部などに配置される。例えば昇降路３の上方などにエレベーター２の機械室が設けられる場合に、制御盤１１は、機械室に配置されてもよい。制御盤１１が制御するエレベーター２の動作は、かご９の走行およびかごドア１２の開閉などを含む。例えば、制御盤１１は、登録された呼びに応答させるように、かご９を複数の階床の間で走行させる。制御盤１１は、かご９をいずれかの階床に停止させるときに、乗場ドア６を連動させてかごドア１２を開く。制御盤１１は、予め設定された戸開時間の間、かごドア１２および乗場ドア６の全開の状態を維持する。制御盤１１は、かごドア１２が全開してから戸開時間が経過した後に、乗場ドア６を連動させてかごドア１２を閉める。 The control panel 11 is a device that controls the operation of the elevator 2. The control panel 11 is arranged, for example, at the upper or lower part of the hoistway 3. For example, when the machine room of the elevator 2 is provided above the hoistway 3, the control panel 11 may be arranged in the machine room. The operations of the elevator 2 controlled by the control panel 11 include running the car 9, opening and closing the car door 12, and the like. For example, the control panel 11 causes the car 9 to travel between a plurality of floors so as to respond to a registered call. The control panel 11 opens the car door 12 in conjunction with the landing door 6 when the car 9 is stopped at any floor. The control panel 11 maintains the car door 12 and the landing door 6 in a fully open state during a preset door opening time. The control panel 11 interlocks the landing door 6 to close the car door 12 after the door opening time has elapsed since the car door 12 was fully opened.
　エレベーターシステム１は、遠隔監視装置１３を備える。遠隔監視装置１３は、エレベーター２の状態の遠隔監視などに用いられる装置である。遠隔監視装置１３は、エレベーター２の状態の情報を収集しうるように、制御盤１１などに接続される。遠隔監視装置１３は、例えば制御盤１１に入力される情報および制御盤１１から出力される情報などをエレベーター２の状態の情報として収集する。遠隔監視装置１３が収集した情報は、インターネットまたは電話回線網などの通信網１４を通じて、例えば中央管理装置１５などに出力される。中央管理装置１５は、エレベーター２の状態の情報などの収集、蓄積、または管理などを行う装置である。中央管理装置１５は、例えば情報センターなどに配置される。情報センターは、エレベーター２の状態の情報を収集して管理する拠点である。ここで、エレベーター２の制御盤１１は、エレベーター２の外部から遠隔制御の制御信号などを受け付けてもよい。遠隔制御の制御信号は、例えば遠隔監視装置１３などを通じて制御盤１１に入力される。 The elevator system 1 includes a remote monitoring device 13. The remote monitoring device 13 is a device used to remotely monitor the status of the elevator 2. The remote monitoring device 13 is connected to the control panel 11 and the like so as to collect information on the status of the elevator 2. The remote monitoring device 13 collects, for example, information input to the control panel 11 and information output from the control panel 11 as information on the state of the elevator 2. The information collected by the remote monitoring device 13 is output to, for example, the central management device 15 through a communication network 14 such as the Internet or a telephone line network. The central management device 15 is a device that collects, stores, or manages information on the status of the elevator 2 and the like. The central management device 15 is located at, for example, an information center. The information center is a base that collects and manages information on the status of the elevator 2. Here, the control panel 11 of the elevator 2 may receive a remote control signal or the like from outside the elevator 2. A control signal for remote control is input to the control panel 11 through, for example, the remote monitoring device 13.
　エレベーター２の利用者は、出発階において乗場５からかご９の内部に乗車する。また、利用者は、到着階において、かご９の内部から乗場５に降車する。このようにかご９の乗降のときに、利用者は、乗場５およびかご９の間を通る。乗場５およびかご９の間において、かご９が上下方向に走行しうるように隙間がある。ここで、利用者が乗場５およびかご９の間を行き来するときに、所持している物品を落としてしまうことがある。当該物品は、例えば鍵などのように、乗場５およびかご９の間の隙間より小さいことがある。このとき、当該物品が乗場５およびかご９の間の隙間から昇降路３に落ちてしまい、利用者は当該物品を紛失してしまうことがある。このように紛失物１６となった物品は、昇降路３内の構造物１７の上に乗ったり引っ掛かったりすることで、ピット４まで落下せずに昇降路３内の上下方向におけるいずれかの位置に留まることがある。なお、昇降路３内の構造物１７は、例えば梁もしくは柱、昇降路３内の機器の筐体もしくはケーブル、または昇降路３内の機器を支持するサポートもしくはアームなどを含む。紛失物１６が昇降路３内のいずれかの位置に留まっている場合に、紛失物１６の位置が特定できないとその発見が難しくなることがある。 Users of the elevator 2 board the car 9 from the landing 5 on the departure floor. Further, the user gets off at the landing 5 from inside the car 9 on the arrival floor. In this way, when getting on and off the car 9, the user passes between the landing 5 and the car 9. There is a gap between the landing 5 and the car 9 so that the car 9 can run in the vertical direction. Here, when the user goes back and forth between the landing 5 and the car 9, the user may drop the items he/she is carrying. The item may be smaller than the gap between the landing 5 and the car 9, such as a key. At this time, the article may fall into the hoistway 3 through the gap between the landing 5 and the car 9, and the user may lose the article. By getting onto or getting caught on the structure 17 in the hoistway 3, the lost item 16 can be moved to any vertical position in the hoistway 3 without falling to the pit 4. may remain. Note that the structures 17 in the hoistway 3 include, for example, beams or columns, casings or cables for equipment in the hoistway 3, supports or arms that support equipment in the hoistway 3, and the like. When the lost item 16 remains somewhere in the hoistway 3, it may be difficult to find it if the position of the lost item 16 cannot be specified.
　この例において、利用者は、紛失物１６となった物品を発見するための発信機１８を当該物品に取り付けている。発信機１８は、無線信号を発信する機能を搭載する。発信機１８は、例えば無線タグである。発信機１８が発信する無線信号は、例えば、近距離無線通信などの無線信号である。無線信号は、例えば電磁波による信号などである。無線信号は、例えば無線ＰＡＮ（Ｐｅｒｓｏｎａｌ　Ａｒｅａ　Ｎｅｔｗｏｒｋ）またはＵＷＢ（Ｕｌｔｒａ　Ｗｉｄｅ　Ｂａｎｄ）などの無線信号である。発信機１８は、当該発信機１８を識別する識別情報を含む無線信号を発信する。発信機１８は、無線信号を常時発信していてもよいし、当該発信機１８が取り付けられた物品が紛失されたときに無線信号の発信を開始してもよい。 In this example, the user has attached a transmitter 18 to the lost item 16 for finding the item. The transmitter 18 is equipped with a function of transmitting a wireless signal. The transmitter 18 is, for example, a wireless tag. The wireless signal transmitted by the transmitter 18 is, for example, a wireless signal for short-range wireless communication. The wireless signal is, for example, a signal based on electromagnetic waves. The wireless signal is, for example, a wireless PAN (Personal Area Network) or UWB (Ultra Wide Band) wireless signal. The transmitter 18 transmits a wireless signal that includes identification information that identifies the transmitter 18 . The transmitter 18 may always transmit a wireless signal, or may start transmitting a wireless signal when the article to which the transmitter 18 is attached is lost.
　例えば、建物の通路などにおいて発信機１８が取り付けられた物品が紛失されたときに、当該物品の近傍を通る通行者が所持する携帯端末が発信機１８からの無線信号を受信することがある。このとき、当該通行者の携帯端末から通信網１４および通信網１４に接続されたサーバ装置などを通じて、利用者が所持する携帯端末１９に当該物品の位置などが通知される。利用者が所持する携帯端末１９は、例えば、スマートフォンなどの可搬な汎用の情報処理端末などである。 For example, when an item to which the transmitter 18 is attached is lost in a building passageway, a mobile terminal carried by a passerby passing by the item may receive a wireless signal from the transmitter 18. At this time, the location of the article is notified from the passerby's mobile terminal to the mobile terminal 19 owned by the user through the communication network 14 and the server device connected to the communication network 14 . The mobile terminal 19 carried by the user is, for example, a portable general-purpose information processing terminal such as a smartphone.
　一方、昇降路３内に紛失物１６がある場合に、昇降路３を通行する通行者はいないため、通行者が所持する携帯端末などによっては紛失物１６は発見されない。また、金属などからなるかご９の内部において紛失物１６に取り付けられた発信機１８からの無線信号を受信することは難しく、かご９に乗車している乗客が所持する携帯端末などによって紛失物１６は発見されない。このため、昇降路３内に紛失物１６がある場合に、付近を通行する人の携帯端末によって紛失物１６の位置を特定することは難しい。このため、エレベーターシステム１において、回収支援システム２０が適用される。 On the other hand, if there is a lost item 16 in the hoistway 3, there are no passersby passing through the hoistway 3, so the lost item 16 will not be found by a passerby's mobile terminal or the like. Furthermore, it is difficult to receive a wireless signal from the transmitter 18 attached to the lost item 16 inside the car 9 made of metal, etc. is not discovered. Therefore, when there is a lost item 16 in the hoistway 3, it is difficult to specify the location of the lost item 16 using a mobile terminal of a person passing nearby. For this reason, in the elevator system 1, a recovery support system 20 is applied.
　回収支援システム２０は、エレベーター２の保守員などによる昇降路３内にある紛失物１６の回収を支援するシステムである。回収支援システム２０は、エレベーターシステム１の外部システムであってもよいし、エレベーターシステム１に含まれる内部システムであってもよい。この例において、回収支援システム２０は、エレベーター２の制御盤１１を含む。紛失物１６に取り付けられた発信機１８は、回収支援システム２０の外部装置であってもよいし、内部装置であってもよい。 The recovery support system 20 is a system that supports the recovery of lost items 16 in the hoistway 3 by maintenance personnel of the elevator 2 and the like. The recovery support system 20 may be an external system of the elevator system 1 or an internal system included in the elevator system 1. In this example, the collection support system 20 includes a control panel 11 for the elevator 2. The transmitter 18 attached to the lost item 16 may be an external device of the recovery support system 20, or may be an internal device.
　回収支援システム２０は、受信機２１を含む。受信機２１は、かご９の外側に取り付けられる。この例において、受信機２１は、かご９の下側に取り付けられる。受信機２１は、例えば、かご９の底面に取り付けられる。受信機２１は、かご９の走行に伴って昇降路３内を上下方向に移動する。受信機２１は、紛失物１６に取り付けられた発信機１８が発信する無線信号を受信する機能を搭載する。受信機２１は、例えば発信機１８が発する無線信号の通信範囲内をかご９が通過する間、当該発信機１８からの無線信号を継続して受信する。このとき、受信機２１は、当該無線信号を受信し始めてから受信しなくなるまでの受信期間を、当該無線信号の１回の受信として扱ってもよい。 The collection support system 20 includes a receiver 21. Receiver 21 is attached to the outside of car 9. In this example, receiver 21 is attached to the underside of car 9. The receiver 21 is attached to the bottom surface of the car 9, for example. The receiver 21 moves in the vertical direction within the hoistway 3 as the car 9 travels. The receiver 21 is equipped with a function of receiving a wireless signal transmitted by the transmitter 18 attached to the lost item 16. The receiver 21 continuously receives the radio signal from the transmitter 18 while the car 9 passes within the communication range of the radio signal emitted by the transmitter 18, for example. At this time, the receiver 21 may treat the reception period from when it starts receiving the radio signal until it stops receiving it as one reception of the radio signal.
　制御盤１１は、呼び管理部２２と、走行制御部２３と、取得部２４と、検知部２５と、判定部２６と、報知部２７と、を備える。 The control panel 11 includes a call management section 22, a travel control section 23, an acquisition section 24, a detection section 25, a determination section 26, and a notification section 27.
　呼び管理部２２は、かご９が応答する呼びの管理の機能を搭載する部分である。かご９が応答する呼びは、例えば、利用者の出発階などへの走行に対応する乗場呼び、および利用者の行先階などへの走行に対応するかご呼びなどを含む。 The call management unit 22 is a part equipped with a function of managing calls to which the car 9 responds. The calls to which the car 9 responds include, for example, a landing call corresponding to the user's travel to a departure floor, etc., and a car call corresponding to the user's travel to a destination floor, etc.
　走行制御部２３は、かご９の走行を制御する機能を搭載する部分である。走行制御部２３は、例えば、呼び管理部２２が管理する呼びに応じてかご９を走行させる。走行制御部２３は、かご９の位置情報に基づいてかご９の走行を制御する。走行制御部２３は、例えば、取得部２４が取得するかご９の位置情報に基づいてかご９の走行を制御する。かご９の位置情報は、昇降路３におけるかご９の上下方向の位置を表す情報である。かご９の位置情報は、例えば巻上機７のモータの回転量などに基づいて取得される。エレベーター２においていずれかの階床へのかご９の階床を検知する図示されない着床検知装置などが設けられている場合に、かご９の位置情報は、例えば当該着床検知装置などの検知情報を用いて取得されてもよい。 The travel control unit 23 is a part that is equipped with a function to control the travel of the car 9. The travel control unit 23 causes the car 9 to travel in response to calls managed by the call management unit 22, for example. The travel control unit 23 controls the travel of the car 9 based on the position information of the car 9. The travel control unit 23 controls the travel of the car 9 based on the position information of the car 9 acquired by the acquisition unit 24, for example. The position information of the car 9 is information representing the position of the car 9 in the vertical direction in the hoistway 3. The position information of the car 9 is acquired based on, for example, the amount of rotation of the motor of the hoist 7. If the elevator 2 is provided with a landing detection device (not shown) that detects which floor the car 9 is on, the position information of the car 9 may be, for example, the detection information of the landing detection device, etc. may be obtained using
　この例において、走行制御部２３は、運転モードを切り替えてかご９の走行を制御する。運転モードは、通常運転を含む。通常運転は、利用者などを複数の階床の間で輸送する通常の運転モードである。通常運転において、走行制御部２３は、例えば出発階および行先階に応じて設定される速度パターンなどに従ってかご９を走行させる。速度パターンは、例えば、出発階から出発したかご９を定格速度まで加速させ、定格速度でかご９を定速走行させた後、定格速度からかご９を減速させて行先階に停止させるパターンなどである。 In this example, the travel control unit 23 controls the travel of the car 9 by switching the driving mode. The operation mode includes normal operation. Normal operation is a normal operation mode in which users and the like are transported between multiple floors. During normal operation, the traveling control unit 23 causes the car 9 to travel according to a speed pattern set depending on, for example, the departure floor and the destination floor. The speed pattern is, for example, a pattern in which the car 9 departing from the departure floor is accelerated to the rated speed, the car 9 is run at a constant speed at the rated speed, and then the car 9 is decelerated from the rated speed and stopped at the destination floor. be.
　取得部２４は、かご９の位置情報を取得する機能を搭載する部分である。取得部２４は、受信機２１が発信機１８からの無線信号を受信するときに、そのときのかご９の位置情報を取得する。取得部２４は、受信機２１が発信機１８からの無線信号を受信するときに、例えば走行制御部２３からかご９の位置情報を取得してもよいし、巻上機７のモータの回転量などからかご９の位置情報を直接取得してもよい。また、取得部２４は、受信機２１が発信機１８から受信する無線信号の信号強度の情報を取得する。取得部２４は、例えば、信号強度の情報を受信機２１から取得する。取得部２４は、例えば、受信機２１が発信機１８から無線信号を受信するときに、そのときに取得したかご９の位置情報に対応づけて信号強度の情報を取得する。 The acquisition unit 24 is a part equipped with a function of acquiring position information of the car 9. The acquisition unit 24 acquires the current position information of the car 9 when the receiver 21 receives the wireless signal from the transmitter 18 . When the receiver 21 receives the wireless signal from the transmitter 18, the acquisition unit 24 may acquire the position information of the car 9 from the travel control unit 23, for example, or acquire the rotation amount of the motor of the hoist 7. The location information of the car 9 may also be directly acquired from, for example. The acquisition unit 24 also acquires information on the signal strength of the wireless signal that the receiver 21 receives from the transmitter 18 . The acquisition unit 24 acquires information on signal strength from the receiver 21, for example. For example, when the receiver 21 receives a wireless signal from the transmitter 18, the acquisition unit 24 acquires signal strength information in association with the position information of the car 9 acquired at that time.
　検知部２５は、昇降路３内の紛失物１６に取り付けられた発信機１８から受信機２１が受信する無線信号に基づいて、紛失物１６が昇降路３内にあることを検知する機能を搭載する部分である。検知部２５は、例えば、受信機２１が発信機１８から無線信号を複数回受信したときに、紛失物１６が昇降路３内にあることを検知する。検知部２５は、例えば、受信機２１が発信機１８から無線信号を受信するたびに取得部２４が取得したかご９の位置情報を比較し、取得された複数の位置情報が予め設定された誤差範囲内で一致するときに、紛失物１６が昇降路３内にあることを検知してもよい。誤差範囲は、例えば、発信機１８が発する無線信号の通信範囲を含む程度などに設定される。検知部２５は、例えば、取得された複数の位置情報の最高値および最低値の差が誤差範囲の大きさより小さい場合に、複数の位置情報が誤差範囲内で一致すると判定する。あるいは、検知部２５は、例えば、発信機１８からの無線信号を受信するたびに当該無線信号に含まれる識別情報を読み取り、複数回受信した各々の無線信号に含まれる識別情報が一致するときに、紛失物１６が昇降路３内にあることを検知してもよい。検知部２５は、上述の複数の条件などを組み合わせて紛失物１６が昇降路３内にあることを検知してもよい。なお、検知部２５は、例えば、受信機２１が発信機１８から無線信号を１回受信したときに、紛失物１６が昇降路３内にあることを検知してもよい。 The detection unit 25 is equipped with a function of detecting that the lost item 16 is in the hoistway 3 based on a wireless signal received by the receiver 21 from the transmitter 18 attached to the lost item 16 in the hoistway 3. This is the part to do. The detection unit 25 detects that the lost item 16 is in the hoistway 3, for example, when the receiver 21 receives a wireless signal from the transmitter 18 multiple times. For example, the detection unit 25 compares the position information of the car 9 acquired by the acquisition unit 24 every time the receiver 21 receives a wireless signal from the transmitter 18, and compares the acquired position information with a preset error. When they match within the range, it may be detected that the lost item 16 is in the hoistway 3. The error range is set to include, for example, the communication range of the wireless signal emitted by the transmitter 18. For example, the detection unit 25 determines that the plurality of pieces of positional information match within the error range, when the difference between the highest value and the lowest value of the plurality of pieces of acquired positional information is smaller than the size of the error range. Alternatively, the detection unit 25 reads the identification information included in the radio signal each time it receives a radio signal from the transmitter 18, and when the identification information included in each radio signal received multiple times matches, , it may be detected that the lost item 16 is in the hoistway 3. The detection unit 25 may detect that the lost item 16 is in the hoistway 3 by combining the plurality of conditions described above. Note that the detection unit 25 may detect that the lost item 16 is in the hoistway 3, for example, when the receiver 21 receives a wireless signal from the transmitter 18 once.
　判定部２６は、昇降路３における紛失物１６の上下方向の位置を判定する機能を搭載する部分である。判定部２６は、例えば、紛失物１６が昇降路３内にあることを検知部２５が検知するときに、当該紛失物１６の位置を判定する。判定部２６は、例えば、取得部２４が取得するかご９の位置情報に基づいて、紛失物１６の位置を判定する。判定部２６は、例えば、受信機２１が発信機１８からの無線信号を受信するときに取得部２４が取得したかご９の位置を、紛失物１６の位置として判定する。あるいは、判定部２６は、当該かご９の位置にかご９の高さ、またはかご９における受信機２１の設置位置などに基づく補正値を加えて紛失物１６の位置を判定してもよい。検知部２５が発信機１８からの無線信号の複数回の受信に基づいて紛失物１６を検知する場合に、判定部２６は、各回の受信に対応して取得部２４が取得したかご９の位置の平均値に基づいて紛失物１６の位置を判定してもよい。 The determination unit 26 is a part equipped with a function of determining the vertical position of the lost item 16 in the hoistway 3. For example, when the detection unit 25 detects that the lost item 16 is in the hoistway 3, the determination unit 26 determines the position of the lost item 16. The determining unit 26 determines the position of the lost item 16, for example, based on the position information of the car 9 acquired by the acquiring unit 24. The determining unit 26 determines, for example, the position of the car 9 acquired by the acquiring unit 24 when the receiver 21 receives the wireless signal from the transmitter 18 as the position of the lost item 16. Alternatively, the determining unit 26 may determine the position of the lost item 16 by adding a correction value based on the height of the car 9 or the installation position of the receiver 21 in the car 9 to the position of the car 9. When the detection unit 25 detects the lost item 16 based on multiple receptions of the wireless signal from the transmitter 18, the determination unit 26 detects the position of the car 9 acquired by the acquisition unit 24 in response to each reception. The position of the lost item 16 may be determined based on the average value of .
　報知部２７は、判定部２６が判定した紛失物１６の位置の報知を行う機能を搭載する部分である。報知部２７は、例えば、通信網１４などを通じて中央管理装置１５に報知を行う。あるいは、報知部２７は、エレベーター２の保守員が所持する保守端末などに通信網１４などを通じて報知を行ってもよい。保守端末は、例えば、スマートフォンなどの可搬な汎用の情報処理端末などである。また、報知部２７は、エレベーター２が適用される建物に管理室などが設けられる場合に、管理室に報知を行ってもよい。報知部２７は、発信機１８からの無線信号に含まれる識別情報をあわせて報知を行ってもよい。当該識別情報に基づいて発信機１８が取り付けられた紛失物１６を紛失した利用者の携帯端末１９に通知を行うサーバ装置などがある場合に、報知部２７は、当該サーバ装置に識別情報を報知してもよい。当該識別情報に基づいて発信機１８が取り付けられた紛失物１６を紛失した利用者の携帯端末１９に通知を行う情報が取得できる場合に、報知部２７は、利用者の携帯端末１９にエレベーター２が適用される建物などの情報を報知してもよい。 The notification unit 27 is a part equipped with a function of notifying the location of the lost item 16 determined by the determination unit 26. The notification unit 27 notifies the central management device 15 via the communication network 14, for example. Alternatively, the notification unit 27 may notify a maintenance terminal owned by a maintenance worker of the elevator 2 through the communication network 14 or the like. The maintenance terminal is, for example, a portable general-purpose information processing terminal such as a smartphone. Further, the notification unit 27 may notify the management room when the building to which the elevator 2 is applied is provided with a management room. The notification unit 27 may also notify the identification information included in the wireless signal from the transmitter 18. If there is a server device or the like that notifies the mobile terminal 19 of the lost user of the lost item 16 to which the transmitter 18 is attached based on the identification information, the notification unit 27 notifies the server device of the identification information. You may. When information for notifying the mobile terminal 19 of the user who has lost the lost item 16 to which the transmitter 18 is attached can be obtained based on the identification information, the notification unit 27 sends the elevator 2 to the mobile terminal 19 of the user. It is also possible to broadcast information such as buildings to which the system applies.
　この例において、走行制御部２３が切り替える運転モードは、捜索運転を含む。捜索運転は、昇降路３内にある紛失物１６を捜索する運転モードである。走行制御部２３は、例えば、通常運転での運転中に紛失物１６が昇降路３内にあることを検知部２５が検知したときに、運転モードを捜索運転に切り替える。走行制御部２３は、呼び管理部２２によってかご９に乗場呼びまたはかご呼びが登録されている間、捜索運転への切替を保留してもよい。捜索運転において、走行制御部２３は、捜索範囲の開始位置から終了位置までかご９を走行させる。捜索範囲の開始位置は、当該範囲の上下の境界の一方である。捜索範囲の終了位置は、当該範囲の上下の境界の他方である。捜索範囲は、例えば、通常運転中に受信機２１が発信機１８からの無線信号を受信したかご９の位置を含む。例えば、通常運転においてかご９が階床間の位置にあるときに受信機２１が無線信号を受信するときに、捜索範囲は、当該位置をその間に含むように隣接した階床間の範囲などである。このとき、捜索範囲の開始位置は、隣接した階床の一方の停止位置である。また、捜索範囲の終了位置は、隣接した階床の他方の停止位置である。なお、捜索範囲は、隣接した階床間の範囲に限定されない。捜索運転において、走行制御部２３は、通常運転より低速でかご９を走行させる。走行制御部２３は、例えば、定格速度より低速でかご９を走行させる。あるいは、走行制御部２３は、例えば通常運転における速度パターンに予め設定された係数を乗じて速度を低減させた速度パターンに従ってかご９を走行させてもよい。あるいは、通常運転においてかご９が階床間の位置にあるときに受信機２１が無線信号を受信するときに、走行制御部２３は、そのときのかご９の走行速度より低速でかご９を走行させるように捜索運転をおこなってもよい。 In this example, the driving modes to which the travel control unit 23 switches include search driving. The search operation is an operation mode in which the lost item 16 in the hoistway 3 is searched for. For example, when the detection section 25 detects that the lost item 16 is in the hoistway 3 during normal operation, the travel control section 23 switches the operation mode to search operation. The travel control unit 23 may suspend switching to search operation while the call management unit 22 registers a hall call or a car call for the car 9. In the search operation, the travel control unit 23 causes the car 9 to travel from the start position to the end position of the search range. The starting position of the search range is one of the upper and lower boundaries of the range. The end position of the search range is the other of the upper and lower boundaries of the range. The search range includes, for example, the position of the car 9 where the receiver 21 receives the radio signal from the transmitter 18 during normal operation. For example, when the receiver 21 receives a radio signal when the car 9 is located between floors during normal operation, the search range is a range between adjacent floors that includes the position in between. be. At this time, the starting position of the search range is the stopping position of one of the adjacent floors. Furthermore, the end position of the search range is the other stop position on the adjacent floor. Note that the search range is not limited to the range between adjacent floors. In the search operation, the traveling control unit 23 causes the car 9 to travel at a lower speed than in the normal operation. For example, the traveling control unit 23 causes the car 9 to travel at a speed lower than the rated speed. Alternatively, the traveling control unit 23 may cause the car 9 to travel according to a speed pattern in which the speed is reduced by multiplying the speed pattern in normal operation by a preset coefficient, for example. Alternatively, when the receiver 21 receives a wireless signal when the car 9 is located between floors during normal operation, the travel control unit 23 causes the car 9 to travel at a speed lower than the travel speed of the car 9 at that time. You may also conduct a search drive.
　なお、回収支援システム２０において、受信機２１は、１つのかご９に複数取り付けられてもよい。例えば、１つのかご９の底面および上面などのそれぞれに受信機２１が取り付けられていてもよい。 Note that in the collection support system 20, a plurality of receivers 21 may be attached to one car 9. For example, the receiver 21 may be attached to each of the bottom and top surfaces of one car 9.
　また、回収支援システム２０は、複数のかご９を含むエレベーターシステム１に適用されてもよい。このとき、受信機２１は、各々のかご９に取り付けられていてもよい。あるいは、各々のかご９の走行する昇降路３が壁などで区切られていない場合に、いずれかのかご９において受信機２１が取り付けられていなくてもよい。エレベーターシステム１が複数のかご９を含む場合に、呼び管理部２２は、いずれかのかご９に乗場呼びなどの呼びの割当てを行う機能を有していてもよい。呼び管理部２２は、例えば、図示されない群管理装置などに搭載されていてもよい。 Furthermore, the recovery support system 20 may be applied to an elevator system 1 including a plurality of cars 9. At this time, the receiver 21 may be attached to each car 9. Alternatively, if the hoistway 3 in which each car 9 runs is not separated by a wall or the like, the receiver 21 may not be attached to any of the cars 9. When the elevator system 1 includes a plurality of cars 9, the call management unit 22 may have a function of allocating a call such as a hall call to one of the cars 9. The call management unit 22 may be installed in, for example, a group management device (not shown).
　回収支援システム２０の呼び管理部２２、走行制御部２３、取得部２４、検知部２５、判定部２６、および報知部２７などの各機能の一部または全部は、制御盤１１の他の装置に搭載されていてもよい。これらの機能の一部または全部は、遠隔監視装置１３、中央管理装置１５、群管理装置、または情報センター外のサーバ装置などを含むその他の装置などに搭載されていてもよい。 Some or all of the functions of the collection support system 20, such as the call management section 22, travel control section 23, acquisition section 24, detection section 25, determination section 26, and notification section 27, are connected to other devices of the control panel 11. It may be installed. Some or all of these functions may be installed in the remote monitoring device 13, the central management device 15, the group management device, or other devices including a server device outside the information center.

　図２は、実施の形態１に係る回収支援システム２０の動作の例を示すフローチャートである。
　図２における処理は、例えば、通常運転の間に、予め設定されたタイミングで実行される。当該タイミングは、定期的なタイミングであってもよいし、例えば遠隔監視装置１３などに処理開始の信号が入力されたタイミングなどであってもよい。 Next, an example of the operation of the collection support system 20 will be described using FIG. 2.
FIG. 2 is a flowchart illustrating an example of the operation of the collection support system 20 according to the first embodiment.
The process in FIG. 2 is executed, for example, at a preset timing during normal operation. The timing may be a regular timing, or may be, for example, the timing when a signal to start processing is input to the remote monitoring device 13 or the like.
　ステップＳ０１において、検知部２５は、受信機２１が無線信号を受信したかを判定する。判定結果がＮＯの場合に、回収支援システム２０の処理は、例えば予め設定された時間が経過した後などに、ふたたびステップＳ０１に進む。一方、判定結果がＹＥＳの場合に、回収支援システム２０の処理は、ステップＳ０２に進む。 In step S01, the detection unit 25 determines whether the receiver 21 has received a wireless signal. If the determination result is NO, the process of the collection support system 20 proceeds to step S01 again, for example after a preset time has elapsed. On the other hand, if the determination result is YES, the process of the collection support system 20 proceeds to step S02.
　ステップＳ０２において、検知部２５は、受信機２１が受信した無線信号に含まれる発信機１８の識別情報を読み込む。その後、回収支援システム２０の処理は、ステップＳ０３に進む。 In step S02, the detection unit 25 reads the identification information of the transmitter 18 included in the wireless signal received by the receiver 21. Thereafter, the process of the collection support system 20 proceeds to step S03.
　ステップＳ０３において、取得部２４は、ステップＳ０１で受信機２１が無線信号を受信したときのかご９の位置情報を取得する。その後、回収支援システム２０の処理は、ステップＳ０４に進む。 In step S03, the acquisition unit 24 acquires the position information of the car 9 when the receiver 21 receives the wireless signal in step S01. Thereafter, the process of the collection support system 20 proceeds to step S04.
　ステップＳ０４において、検知部２５は、受信機２１による無線信号の受信回数が予め設定された閾値以上であるかを判定する。閾値は、例えば２回などである。判定結果がＮＯの場合に、回収支援システム２０の処理は、ステップＳ０１に進む。一方、判定結果がＹＥＳの場合に、回収支援システム２０の処理は、ステップＳ０５に進む。 In step S04, the detection unit 25 determines whether the number of times the receiver 21 receives the wireless signal is equal to or greater than a preset threshold. The threshold value is, for example, twice. If the determination result is NO, the processing of the collection support system 20 proceeds to step S01. On the other hand, if the determination result is YES, the process of the collection support system 20 proceeds to step S05.
　ステップＳ０５において、検知部２５は、閾値以上の回数受信した無線信号の各々に含まれる発信機１８の識別情報が一致するかを判定する。判定結果がＮＯの場合に、回収支援システム２０の処理は、ステップＳ０１に進む。一方、判定結果がＹＥＳの場合に、回収支援システム２０の処理は、ステップＳ０６に進む。 In step S05, the detection unit 25 determines whether the identification information of the transmitter 18 included in each of the wireless signals received a number of times equal to or greater than a threshold value match. If the determination result is NO, the processing of the collection support system 20 proceeds to step S01. On the other hand, if the determination result is YES, the process of the collection support system 20 proceeds to step S06.
　ステップＳ０６において、検知部２５は、閾値以上の無線信号の各回の受信についてステップＳ０３で取得したかご９の位置情報を比較する。検知部２５は、各回のかご９の位置情報が誤差範囲内で一致するかを判定する。判定結果がＮＯの場合に、回収支援システム２０の処理は、ステップＳ０１に進む。一方、判定結果がＹＥＳの場合に、回収支援システム２０の処理は、ステップＳ０７に進む。 In step S06, the detection unit 25 compares the position information of the car 9 acquired in step S03 for each reception of a wireless signal equal to or higher than the threshold value. The detection unit 25 determines whether the position information of the car 9 each time matches within the error range. If the determination result is NO, the processing of the collection support system 20 proceeds to step S01. On the other hand, if the determination result is YES, the process of the collection support system 20 proceeds to step S07.
　ステップＳ０７において、検知部２５は、紛失物１６が昇降路３内にあることを検知する。その後、回収支援システム２０の処理は、ステップＳ０８に進む。 In step S07, the detection unit 25 detects that the lost item 16 is in the hoistway 3. Thereafter, the process of the collection support system 20 proceeds to step S08.
　ステップＳ０８において、走行制御部２３は、捜索運転の準備処理を行う。捜索運転の準備処理は、例えば、捜索範囲および捜索運転におけるかご９の低速の走行速度の設定を含む。捜索範囲は、例えば、ステップＳ０３において取得されたかご９の位置を含むように設定される。かご９の走行速度は、例えば定格速度より低い予め定められた速度に設定される。あるいは、かご９の走行速度は、ステップＳ０１において受信機２１が無線信号を受信したときのかご９の走行速度より低い速度に設定される。このとき、かご９は、例えば定格速度で走行している。かご９の走行速度は、例えば取得部２４が走行制御部２３などから取得してもよいし、取得部２４が取得する位置情報などに基づいて算出されてもよい。その後、回収支援システム２０の処理は、ステップＳ０９に進む。 In step S08, the travel control unit 23 performs search drive preparation processing. The search operation preparation process includes, for example, setting the search range and the low running speed of the car 9 during the search operation. The search range is set to include, for example, the position of the car 9 acquired in step S03. The traveling speed of the car 9 is set, for example, to a predetermined speed lower than the rated speed. Alternatively, the running speed of the car 9 is set to a lower speed than the running speed of the car 9 when the receiver 21 receives the wireless signal in step S01. At this time, the car 9 is running at, for example, the rated speed. The travel speed of the car 9 may be acquired by the acquisition unit 24 from the travel control unit 23 or the like, or may be calculated based on the position information acquired by the acquisition unit 24, for example. Thereafter, the process of the collection support system 20 proceeds to step S09.
　ステップＳ０９において、走行制御部２３は、呼び管理部２２によってかご９に呼びが登録されているかを判定する。判定の対象となる呼びは、例えば乗場呼びおよびかご呼びを含む。かご９に少なくとも１つ呼びが登録されている場合に、回収支援システム２０の処理は、例えば予め設定された時間が経過した後などに、ふたたびステップＳ０９に進む。一方、かご９に１つも呼びが登録されていない場合に、回収支援システム２０の処理は、ステップＳ１０に進む。 In step S09, the travel control unit 23 determines whether a call is registered in the car 9 by the call management unit 22. Calls to be determined include, for example, hall calls and car calls. If at least one call is registered in the car 9, the process of the collection support system 20 proceeds to step S09 again, for example after a preset time has elapsed. On the other hand, if no call is registered in the car 9, the process of the collection support system 20 proceeds to step S10.
　ステップＳ１０において、走行制御部２３は、捜索運転を開始する。走行制御部２３は、ステップＳ０８で設定した捜索範囲の開始位置までかご９を走行させる。その後、走行制御部２３は、ステップＳ０８で設定した捜索範囲の終了位置まで、ステップＳ０８で設定した低速の走行速度でかご９を走行させる。かご９が捜索範囲を走行しているときに、受信機２１が無線信号を受信している間、取得部２４は、無線信号の信号強度をかご９の位置に対応づけて取得する。捜索範囲の終了位置までかご９が走行したときに、走行制御部２３は、捜索運転を終了する。この時、走行制御部２３は、運転モードを通常運転に切り替える。その後、回収支援システム２０の処理は、ステップＳ１１に進む。 In step S10, the travel control unit 23 starts search driving. The traveling control unit 23 causes the car 9 to travel to the starting position of the search range set in step S08. Thereafter, the travel control unit 23 causes the car 9 to travel at the low travel speed set in step S08 to the end position of the search range set in step S08. While the car 9 is traveling in the search range and the receiver 21 is receiving the wireless signal, the acquisition unit 24 acquires the signal strength of the wireless signal in association with the position of the car 9. When the car 9 has traveled to the end position of the search range, the travel control unit 23 ends the search operation. At this time, the travel control unit 23 switches the driving mode to normal driving. Thereafter, the process of the collection support system 20 proceeds to step S11.
　ステップＳ１１において、判定部２６は、ステップＳ１０で取得部２４が取得した信号強度が最大となるかご９の位置を算出する。判定部２６は、算出したかご９の位置に基づいて、紛失物１６の位置を判定する。判定部２６は、例えば、算出したかご９の位置を、紛失物１６の位置として判定する。あるいは、判定部２６は、算出したかご９の位置に、かご９の高さまたはかご９における受信機２１の設置位置などに基づく補正値を加えて紛失物１６の位置を判定してもよい。その後、回収支援システム２０の処理は、ステップＳ１２に進む。 In step S11, the determination unit 26 calculates the position of the car 9 where the signal strength acquired by the acquisition unit 24 in step S10 is maximum. The determining unit 26 determines the position of the lost item 16 based on the calculated position of the car 9. For example, the determining unit 26 determines the calculated position of the car 9 as the position of the lost item 16. Alternatively, the determining unit 26 may determine the position of the lost item 16 by adding a correction value based on the height of the car 9 or the installation position of the receiver 21 in the car 9 to the calculated position of the car 9. Thereafter, the process of the collection support system 20 proceeds to step S12.
　ステップＳ１２において、報知部２７は、ステップＳ１１で判定部２６が判定した紛失物１６の位置、およびステップＳ０２で読み込んだ発信機１８の識別情報を報知する。その後、回収支援システム２０の処理は、終了する。 In step S12, the notification unit 27 notifies the location of the lost item 16 determined by the determination unit 26 in step S11 and the identification information of the transmitter 18 read in step S02. Thereafter, the processing of the collection support system 20 ends.
　紛失物１６の回収作業を行う保守員は、例えば保守端末などを通じて、報知部２７が報知した情報を得る。保守員は、エレベーター２が適用される建物に到着した後に、エレベーター２の運転モードを通常運転から手動運転に切り替える。手動運転は、保守作業などの際に保守員が手動で運転を行う運転モードである。その後、保守員は、紛失物１６の回収作業を開始する。紛失物１６の回収作業において、保守員は、手動運転などによって報知部２７が報知した紛失物１６の位置の付近でかご９を運転しながら、昇降路３において紛失物１６を捜索する。保守員は、紛失物１６を発見して回収した後に、エレベーター２の運転モードを手動運転から通常運転に復旧する。 A maintenance worker who performs the work of recovering the lost item 16 obtains the information reported by the notification unit 27, for example, through a maintenance terminal. After arriving at the building to which the elevator 2 is applied, the maintenance worker switches the operation mode of the elevator 2 from normal operation to manual operation. Manual operation is an operation mode in which maintenance personnel manually operate the system during maintenance work or the like. After that, the maintenance person starts collecting the lost item 16. In the work of recovering the lost item 16, the maintenance worker searches for the lost item 16 in the hoistway 3 while driving the car 9 near the position of the lost item 16 notified by the notification unit 27 by manual operation or the like. After finding and recovering the lost item 16, the maintenance worker restores the operation mode of the elevator 2 from manual operation to normal operation.
　なお、回収支援システム２０において、捜索運転は行われなくてもよい。このとき、判定部２６は、例えば、通常運転中に受信機２１が発信機１８からの無線信号を受信したときに取得部２４が取得したかご９の位置に基づいて紛失物１６の位置を判定する。また、取得部２４が取得するかご９の位置情報は、最下階または最上階などからのかご９の走行距離で表されてもよいし、建物における階床番号などの階床の情報で表されてもよい。 Note that in the recovery support system 20, search driving may not be performed. At this time, the determination unit 26 determines the position of the lost item 16 based on the position of the car 9 acquired by the acquisition unit 24 when the receiver 21 receives a wireless signal from the transmitter 18 during normal operation, for example. do. Further, the position information of the car 9 acquired by the acquisition unit 24 may be expressed by the distance traveled by the car 9 from the bottom floor or the top floor, or may be expressed by floor information such as the floor number in the building. may be done.
　以上に説明したように、実施の形態１に係る回収支援システム２０は、受信機２１と、検知部２５と、取得部２４と、判定部２６と、報知部２７と、を備える。受信機２１は、昇降路３を上下方向に走行するかご９の外側に取り付けられる。受信機２１は、発信機１８が発信する無線信号を受信する。発信機１８は、昇降路３内にある紛失物１６に取り付けられている。発信機１８は、利用者が当該紛失物１６を紛失したときに無線信号を発信する。検知部２５は、受信機２１が発信機１８から受信する無線信号に基づいて、紛失物１６が昇降路３内にあることを検知する。取得部２４は、受信機２１が発信機１８からの無線信号を受信するときのかご９の位置情報を取得する。かご９の位置情報は、昇降路３におけるかご９の上下方向の位置を表す。判定部２６は、紛失物１６が昇降路３内にあることを検知部２５が検知するときに、取得部２４が取得するかご９の位置情報に基づいて、昇降路３における紛失物１６の上下方向の位置を判定する。報知部２７は、判定部２６が判定した紛失物１６の位置を報知する。
　また、実施の形態１に係る回収支援方法は、受信ステップと、検知ステップと、取得ステップと、判定ステップと、報知ステップと、を備える。受信ステップは、受信機２１によって、昇降路３内にある紛失物１６に取り付けられている発信機１８が発信する無線信号を受信するステップである。検知ステップは、受信機２１が発信機１８から受信する無線信号に基づいて、紛失物１６が昇降路３内にあることを検知するステップである。取得ステップは、受信機２１が発信機１８からの無線信号を受信するときのかご９の位置情報を取得するステップである。判定ステップは、紛失物１６が昇降路３内にあることを検知ステップにおいて検知するときに、取得ステップにおいて取得するかご９の位置情報に基づいて昇降路３における紛失物１６の上下方向の位置を判定するステップである。報知ステップは、判定ステップにおいて判定した紛失物１６の位置を報知するステップである。 As described above, the collection support system 20 according to the first embodiment includes the receiver 21, the detection section 25, the acquisition section 24, the determination section 26, and the notification section 27. The receiver 21 is attached to the outside of the car 9 that travels in the vertical direction on the hoistway 3. The receiver 21 receives the radio signal transmitted by the transmitter 18. The transmitter 18 is attached to the lost item 16 in the hoistway 3. The transmitter 18 transmits a wireless signal when the user loses the lost item 16. The detection unit 25 detects that the lost item 16 is in the hoistway 3 based on the radio signal that the receiver 21 receives from the transmitter 18 . The acquisition unit 24 acquires the position information of the car 9 when the receiver 21 receives the wireless signal from the transmitter 18. The position information of the car 9 represents the position of the car 9 in the vertical direction in the hoistway 3. The determination unit 26 determines whether the lost item 16 is located above or below the hoistway 3 based on the position information of the car 9 acquired by the acquisition unit 24 when the detection unit 25 detects that the lost item 16 is in the hoistway 3. Determine the position of the direction. The notification unit 27 notifies the location of the lost item 16 determined by the determination unit 26.
Further, the collection support method according to the first embodiment includes a receiving step, a detecting step, an acquiring step, a determining step, and a notification step. The receiving step is a step in which the receiver 21 receives a radio signal transmitted by the transmitter 18 attached to the lost item 16 in the hoistway 3. The detection step is a step in which the receiver 21 detects that the lost item 16 is in the hoistway 3 based on the radio signal received from the transmitter 18. The acquisition step is a step of acquiring the position information of the car 9 when the receiver 21 receives the wireless signal from the transmitter 18. The determination step determines the vertical position of the lost item 16 in the hoistway 3 based on the position information of the car 9 acquired in the acquisition step when the detection step detects that the lost item 16 is in the hoistway 3. This is the step of determining. The notification step is a step of notifying the location of the lost item 16 determined in the determination step.
　このような構成により、エレベーター２の昇降路３にある紛失物１６が無線信号に基づいて検知され、その位置が報知される。紛失物１６の位置が報知されない場合に、保守員は、利用者が当該紛失物１６を紛失したと証言する階床より下方の範囲全てを捜索する必要がある。また、利用者が当該紛失物１６を紛失した階床が明確でない場合に、保守員は、昇降路３の全範囲を捜索する場合がある。回収支援システム２０においては紛失物１６の位置が報知されるので、捜索の範囲を絞り込むことができ、紛失物１６がより回収しやすくなる。これにより、紛失物１６の回収作業が速やかに行われるようになるので、回収作業中でエレベーター２が利用できないダウンタイムが短くなる。このため、エレベーター２の稼働率がより高められる。 With such a configuration, the lost item 16 in the hoistway 3 of the elevator 2 is detected based on a wireless signal, and its position is notified. If the location of the lost item 16 is not reported, the maintenance staff needs to search the entire area below the floor where the user claims to have lost the lost item 16. Furthermore, if the floor where the user lost the lost item 16 is not clear, the maintenance staff may search the entire area of the hoistway 3. Since the recovery support system 20 notifies the location of the lost item 16, the search range can be narrowed down and the lost item 16 can be recovered more easily. As a result, the recovery work for the lost item 16 can be carried out quickly, and the downtime during which the elevator 2 cannot be used during the recovery work is shortened. Therefore, the operating rate of the elevator 2 can be further increased.
　また、検知部２５は、受信機２１が発信機１８から無線信号を複数回受信するときに、紛失物１６が昇降路３内にあることを検知する。 Further, the detection unit 25 detects that the lost item 16 is in the hoistway 3 when the receiver 21 receives the wireless signal from the transmitter 18 multiple times.
　このような構成により、紛失物１６の誤検知などが抑制されるので、報知部２７が報知する情報の信頼性がより高められる。例えば、乗場５にいる利用者が所持する物品に取り付けられた発信機１８が無線信号を発信している場合に、当該無線信号の受信などによる紛失物１６の誤検知が抑制される。 With such a configuration, erroneous detection of the lost item 16 is suppressed, so the reliability of the information reported by the notification unit 27 is further increased. For example, when the transmitter 18 attached to an item owned by a user in the landing hall 5 is transmitting a wireless signal, false detection of the lost item 16 due to reception of the wireless signal is suppressed.
　また、検知部２５は、受信機２１が発信機１８から無線信号を複数回受信し、かつ、各回の無線信号の受信について取得部２４が取得するかご９の位置情報が予め設定された誤差範囲内で一致するときに、紛失物１６が昇降路３内にあることを検知する。 The detection unit 25 also detects that the receiver 21 receives the wireless signal from the transmitter 18 a plurality of times, and the position information of the car 9 acquired by the acquisition unit 24 for each reception of the wireless signal falls within a preset error range. When the numbers match, it is detected that the lost item 16 is in the hoistway 3.
　このような構成により、紛失物１６の誤検知などが抑制されるので、報知部２７が報知する情報の信頼性がより高められる。例えば、遮蔽物または反射体などの無線信号の伝播条件などの環境の変化によって無線信号が偶然受信されるような場合であっても、このような無線信号の受信などによる紛失物１６の誤検知が抑制される。 With such a configuration, erroneous detection of the lost item 16 is suppressed, so the reliability of the information reported by the notification unit 27 is further increased. For example, even if a wireless signal is accidentally received due to a change in the environment such as the propagation conditions of the wireless signal such as a shield or a reflector, the misdetection of the lost item 16 due to reception of such a wireless signal may occur. is suppressed.
　また、発信機１８は、自身の識別情報を含む無線信号を発信する。この場合に、検知部２５は、受信機２１が発信機１８から無線信号を複数回受信し、かつ、受信した各々の無線信号に含まれる識別情報が一致するときに、紛失物１６が昇降路３内にあることを検知する。 Additionally, the transmitter 18 transmits a wireless signal containing its own identification information. In this case, the detection unit 25 detects that the lost item 16 is located in the hoistway when the receiver 21 receives the wireless signal from the transmitter 18 multiple times and the identification information included in each received wireless signal matches. Detects that it is within 3.
　このような構成により、紛失物１６の誤検知などが抑制されるので、報知部２７が報知する情報の信頼性がより高められる。例えば、乗場５にいる利用者が所持する物品に取り付けられた発信機１８が無線信号を発信している場合に、当該無線信号の受信などによる紛失物１６の誤検知が抑制される。特に、混雑時などにおいて、発信機１８が取り付けられた物品を各々が所持する複数の利用者が乗場５に順次訪れる場合であっても、これらの発信機１８が発する無線信号などによる紛失物１６の誤検知が抑制される。 With such a configuration, erroneous detection of the lost item 16 is suppressed, so the reliability of the information reported by the notification unit 27 is further increased. For example, when the transmitter 18 attached to an item owned by a user in the landing hall 5 is transmitting a wireless signal, false detection of the lost item 16 due to reception of the wireless signal is suppressed. In particular, even when a plurality of users, each carrying an item to which a transmitter 18 is attached, visit the landing 5 one after another, such as during busy times, lost items 16 may be detected by wireless signals emitted by these transmitters 18. false positives are suppressed.
　また、回収支援システム２０は、走行制御部２３を備える。走行制御部２３は、受信機２１が発信機１８から受信する無線信号に基づいて紛失物１６が昇降路３内にあることを検知部２５が検知したときに、かご９に低速で捜索範囲を走行させる捜索運転を行う。捜索範囲は、受信機２１が当該無線信号を受信したときのかご９の位置を含む。捜索運転におけるかご９の走行速度は、受信機２１が当該無線信号を受信したときの走行速度より低い速度である。判定部２６は、捜索運転の間に取得部２４が取得するかご９の位置情報に基づいて、昇降路３における紛失物１６の上下方向の位置を判定する。判定部２６は、例えば、捜索運転中に受信機２１が無線信号の受信を開始した位置から受信機２１が無線信号の受信を終了する位置までの中点などを紛失物１６の位置として判定してもよい。 The recovery support system 20 also includes a travel control section 23. When the detection unit 25 detects that the lost item 16 is in the hoistway 3 based on the radio signal that the receiver 21 receives from the transmitter 18, the travel control unit 23 causes the car 9 to search the search range at low speed. Carry out a search drive. The search range includes the position of the car 9 when the receiver 21 receives the wireless signal. The traveling speed of the car 9 during the search operation is lower than the traveling speed when the receiver 21 receives the radio signal. The determination unit 26 determines the vertical position of the lost item 16 in the hoistway 3 based on the position information of the car 9 acquired by the acquisition unit 24 during the search operation. The determining unit 26 determines, for example, the midpoint between the position where the receiver 21 starts receiving the wireless signal and the position where the receiver 21 ends receiving the wireless signal during the search operation as the position of the lost item 16. It's okay.
　このような構成により、紛失物１６の位置がより正確に判定されるようになる。また、捜索範囲が絞り込まれることで、捜索運転において低速で運転される時間がより短くなる。このため、巻上機７のモータまたは当該モータに交流電力を供給するインバータなどの回路の負荷が低減される。 With such a configuration, the position of the lost item 16 can be determined more accurately. Furthermore, by narrowing down the search range, the time spent at low speed during search driving becomes shorter. Therefore, the load on the motor of the hoisting machine 7 or a circuit such as an inverter that supplies AC power to the motor is reduced.
　また、取得部２４は、捜索運転の間に、かご９の昇降路３における上下方向の位置に対応付けて、受信機２１が受信する無線信号の信号強度の情報を取得する。判定部２６は、昇降路３における紛失物１６の上下方向の位置の判定において、取得部２４が取得する信号強度の情報を用いる。 Additionally, the acquisition unit 24 acquires information on the signal strength of the wireless signal received by the receiver 21 in association with the vertical position of the car 9 in the hoistway 3 during the search operation. The determination unit 26 uses the signal strength information acquired by the acquisition unit 24 in determining the vertical position of the lost item 16 in the hoistway 3.
　このような構成により、無線信号の信号強度に基づいて、紛失物１６の位置がより正確に判定されるようになる。 With such a configuration, the location of the lost item 16 can be determined more accurately based on the signal strength of the wireless signal.
　また、走行制御部２３は、かご９に呼びが登録されている間、捜索運転を保留する。 Further, the travel control unit 23 suspends the search operation while the call is registered in the car 9.
　このような構成により、利用者がエレベーター２を利用していない間に捜索運転が行われるようになる。このため、捜索運転によって利用者の利便性が低下しにくくなる。 With such a configuration, the search operation can be performed while the elevator 2 is not used by the user. Therefore, the user's convenience is less likely to deteriorate due to search driving.
　また、受信機２１は、かご９の下側に取り付けられる。 Additionally, the receiver 21 is attached to the lower side of the car 9.
　このような構成により、受信機２１は、かご９の下方からの無線信号を受信しやすくなる。紛失物１６は、昇降路３においてかご９より下方に落下するため、受信機２１は、紛失物１６に取り付けられた発信機１８からの無線信号を受信しやすくなる。 With such a configuration, the receiver 21 can easily receive wireless signals from below the car 9. Since the lost item 16 falls below the car 9 in the hoistway 3, the receiver 21 can easily receive the wireless signal from the transmitter 18 attached to the lost item 16.
　続いて、図３を用いて、回収支援システム２０のハードウェア構成の例について説明する。

The memory 100b is configured of a nonvolatile or volatile semiconductor memory such as RAM, ROM, flash memory, EPROM, and EEPROM.
　処理回路が専用ハードウェア２００を備える場合、処理回路は、例えば、単一回路、複合回路、プログラム化したプロセッサ、並列プログラム化したプロセッサ、ＡＳＩＣ、ＦＰＧＡ、またはこれらの組み合わせで実現される。 When the processing circuit comprises dedicated hardware 200, the processing circuit is implemented, for example, as a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination thereof.
　回収支援システム２０における処理の各機能は、それぞれ処理回路で実現することができる。あるいは、回収支援システム２０の各機能は、まとめて処理回路で実現することもできる。回収支援システム２０の各機能について、一部を専用ハードウェア２００で実現し、他部をソフトウェアまたはファームウェアで実現してもよい。このように、処理回路は、専用ハードウェア２００、ソフトウェア、ファームウェア、またはこれらの組み合わせで回収支援システム２０の各機能を実現する。 Each function of processing in the collection support system 20 can be realized by a processing circuit.
