　駆動装置３０は、被介助者Ｈの上半身を支持する支持部材４０を基台２０の上下方向および前後方向に移動可能に支持する。本実施形態において、駆動装置３０は、昇降部３１および揺動部３２を備える。駆動装置３０は、制御装置６０により昇降部３１および揺動部３２の動作を制御される。駆動装置３０は、昇降部３１の上下動および揺動部３２の旋回動を協調させることにより、支持部材４０を所定の移動軌跡に沿って移動可能に構成される。 The drive device 30 supports the support member 40 that supports the upper body of the care recipient H so as to be movable in the up-down direction and the front-back direction of the base 20. In the present embodiment, the driving device 30 includes a lifting unit 31 and a swing unit 32. The operation of the lifting unit 31 and the swing unit 32 of the driving device 30 is controlled by the control device 60. The driving device 30 is configured to be able to move the support member 40 along a predetermined movement trajectory by coordinating the vertical movement of the elevating unit 31 and the turning movement of the swing unit 32.
　昇降部３１は、基台２０に対して上下方向に直動する。昇降部３１は、上下方向に長い長尺状に形成され、支柱２２の後面のガイド（図示しない）に案内される。昇降部３１は、直動装置（図示しない）の駆動によって支柱２２のガイドに沿って昇降する。昇降部３１の内部には、揺動部３２を旋回させるモータ（図示しない）が収容される。昇降部３１は、揺動支持部３１１を有する。揺動支持部３１１は、揺動部３２を中心軸Ａ周りに回転可能に支持する。 (4) The elevating unit 31 moves vertically with respect to the base 20. The elevating unit 31 is formed in a long shape that is long in the vertical direction, and is guided by a guide (not shown) on the rear surface of the column 22. The elevating unit 31 moves up and down along the guide of the support 22 by driving a linear motion device (not shown). A motor (not shown) for rotating the swing unit 32 is housed inside the elevating unit 31. The elevating unit 31 has a swing support unit 311. The swing support portion 311 supports the swing portion 32 so as to be rotatable around the central axis A.

The arm 322 is integrally fixed to the swing main body 321. One end of the arm 322 is rotatably supported around the central axis A of the swing support 311 of the elevating unit 31.
　アーム３２２は、モータの駆動によって回転される。介助装置１０が起立動作の補助を行う場合には、アーム３２２は、後方に延びた状態から主として前旋回する。一方で、介助装置１０が着座動作の補助を行う場合には、アーム３２２は、後方に延びる状態となるように主として後旋回する。上記のような構成により、揺動部３２は、基台２０の左右方向に平行な水平軸（中心軸Ａ）周りに旋回して、アーム３２２の先端側の揺動本体３２１に取り付けられた支持部材４０を揺動させる。 The arm 322 is rotated by driving a motor. When the assisting device 10 assists the erecting operation, the arm 322 mainly turns forward from the state of extending rearward. On the other hand, when the assisting device 10 assists the sitting operation, the arm 322 mainly turns rearward so as to extend rearward. With the above-described configuration, the swing unit 32 pivots around a horizontal axis (central axis A) parallel to the left-right direction of the base 20, and is supported by the swing body 321 on the distal end side of the arm 322. The member 40 is swung.
　支持部材４０は、被介助者Ｈの上半身を支持する部材である。支持部材４０は、胴体支持部４１および一対の脇支持部４２を備える。胴体支持部４１は、被介助者Ｈの胴体形状に近い面状に形成されており、柔軟な変形が可能になっている。胴体支持部４１の支持面は、被介助者Ｈの上半身のうち胴体の前面に面接触して胴体を支持する。より詳細には、胴体支持部４１の支持面は、被介助者Ｈにおける胸部から腹部に亘る範囲を下方から支持する。また、胴体支持部４１は、揺動本体３２１に取り付けられている。 The support member 40 is a member that supports the upper body of the care recipient H.

The side support portion 42 is swingably supported by the body support portion 41. The side support portion 42 is formed in an L shape by a rod-shaped member. The surface of the side support portion 42 is covered with a material that can be flexibly deformed.
　操作装置５０は、介助装置１０が補助する各種動作に対応した複数のボタンを有する。本実施形態において、操作装置５０は、起立動作、着座動作、上昇動作、および下降動作の順に対応する起立ボタン５１、着座ボタン５２、上昇ボタン５３、および下降ボタン５４を有する。上記の操作装置５０は、例えば伸縮可能な信号ケーブルを介して制御装置６０に接続される。操作装置５０は、何れかのボタンが押下された場合に、ボタンの種別に応じた信号をボタンが押下されている期間、制御装置６０に送出する。 The operation device 50 has a plurality of buttons corresponding to various operations assisted by the assistance device 10. In the present embodiment, the operation device 50 includes a standing button 51, a sitting button 52, a rising button 53, and a descending button 54, which correspond to the standing operation, the sitting operation, the rising operation, and the descending operation in this order. The operation device 50 is connected to the control device 60 via, for example, an extendable signal cable. When any one of the buttons is pressed, the operation device 50 sends a signal corresponding to the type of the button to the control device 60 while the button is being pressed.
　なお、上記の「上昇動作」とは、現在における被介助者Ｈの上半身の角度を維持しつつ上昇させる動作である。また、上記の「下降動作」とは、現在における被介助者Ｈの上半身の角度を維持しつつ下降させる動作である。上昇動作および下降動作において、支持部材４０は、中心軸Ａ周りに旋回しない。 The “elevating operation” is an operation of elevating the care receiver H while maintaining the current angle of the upper body. Further, the above-mentioned “down movement” is an operation of lowering the care receiver H while maintaining the current angle of the upper body. In the raising operation and the lowering operation, the support member 40 does not pivot around the central axis A.
　制御装置６０は、駆動装置３０の昇降部３１および揺動部３２の動作を制御する。制御装置６０は、被介助者Ｈの起立動作や着座動作を補助する動作処理において、操作装置５０に対する操作に基づいて、昇降部３１および揺動部３２を動作させる。制御装置６０は、起立動作および着座動作を実行する場合には、昇降部３１の上下動および揺動部３２の旋回動を協調させて支持部材４０の移動を制御する。 The control device 60 controls the operation of the elevating unit 31 and the swinging unit 32 of the driving device 30. The control device 60 operates the elevating unit 31 and the swing unit 32 based on the operation on the operation device 50 in the operation process for assisting the care receiver H in the standing operation and the sitting operation. When performing the standing operation and the sitting operation, the control device 60 controls the movement of the support member 40 by coordinating the vertical movement of the elevating unit 31 and the turning movement of the swing unit 32.
　制御装置６０は、例えば介助装置１０のエラー時に原因を特定するために、介助装置１０の動作をトレース可能とするログデータＭ１を記録する。「ログデータＭ１」には、起立動作および着座動作を含む各種動作の動作履歴、および各種動作の実行を要求した各種操作の操作履歴の少なくとも一方が含まれる。本実施形態において、ログデータＭ１には、図３に示すように、操作履歴、動作履歴、介助装置の状態、および識別情報が含まれる。上記の「操作履歴」は、操作装置５０に対する操作の開始時刻および終了時刻を示す。 The control device 60 records log data M1 that enables the operation of the assistance device 10 to be traced, for example, to identify the cause of the error of the assistance device 10 when an error occurs. The “log data M1” includes at least one of operation histories of various operations including a standing operation and a sitting operation, and operation histories of various operations that have requested execution of various operations. In the present embodiment, the log data M1 includes, as shown in FIG. 3, an operation history, an operation history, a state of the assisting device, and identification information. The “operation history” indicates a start time and an end time of an operation performed on the operation device 50.
　上記の「動作履歴」は、操作装置５０に対する各種操作に応じて実際に制御装置６０が制御した駆動装置３０の動作の開始時刻、終了時刻、およびこれらの差分に相当する実行時間が含まれる。ここで、制御装置６０は、操作装置５０の何れかのボタンが押下されている間のみ駆動装置３０が動作するように制御する。そのため、操作履歴と動作履歴は、概ね一致する。但し、操作履歴と動作履歴は、制御装置６０がキャンセル処理を実行した場合に不一致となる。 The “operation history” includes a start time and an end time of the operation of the drive device 30 actually controlled by the control device 60 in accordance with various operations on the operation device 50, and an execution time corresponding to a difference therebetween. Here, the control device 60 controls the drive device 30 to operate only while any button of the operation device 50 is pressed. Therefore, the operation history and the operation history generally match. However, the operation history and the operation history do not match when the control device 60 executes the cancel processing.
　詳細には、制御装置６０は、所定の動作が実行中である場合、または介助装置１０における可動部（昇降部３１、揺動部３２）の位置が機械的または制御的な可動域の移動リミットに達している場合に、各種動作の実行を要求する各種操作の少なくとも一部に応じないキャンセル処理を実行する。具体的には、操作装置５０の何れかのボタンに対する操作が終了した直後で可動部が減速中である場合には、制御装置６０は、次のボタンが押下されたとしても当該ボタンに対応して要求される各種動作の実行をキャンセルする。 More specifically, the control device 60 determines whether the position of the movable unit (elevating unit 31, swing unit 32) in the assisting device 10 is mechanical or controllable when the predetermined operation is being performed. In the case where the number of operations has been reached, a cancel process that does not respond to at least a part of various operations that require execution of various operations is executed. Specifically, when the movable unit is decelerating immediately after the operation on any of the buttons of the operation device 50 is completed, the control device 60 responds to the button even if the next button is pressed. To cancel the execution of various operations requested.
　また、制御装置６０は、例えば昇降部３１が可動域の移動リミット、即ち機械的または制御的な上昇端に達している場合には、それ以上の上昇動作および起立動作をキャンセルする。一方で、上記の例においては、制御装置６０は、上昇端からの下降動作および着座動作についてはキャンセルの対象とせずに、要求に応じた動作を実行する。制御装置６０は、操作と動作が一致する場合には動作の記録を省略し、操作と動作が不一致の場合に動作を記録するようにしてもよい。 {Circle around (5)} For example, when the elevating unit 31 has reached the movement limit of the movable range, that is, the mechanically or controlly ascending end, the control unit 60 cancels the further ascent and standing operations. On the other hand, in the above-described example, the control device 60 performs the operation according to the request without making the descending operation and the sitting operation from the rising end as cancellation targets. The control device 60 may omit the recording of the operation when the operation and the operation match, and record the operation when the operation and the operation do not match.
　ログデータＭ１に含まれる「介助装置の状態」は、可動部（昇降部３１、揺動部３２）の状態、または駆動装置３０における動作機構（直動装置、モータなど）の状態としてもよい。可動部の状態は、例えば昇降部３１の上下方向の位置、揺動部３２の角度が含まれる。これらは、例えば昇降部３１を昇降させる直動装置に設けられたリニアスケール、アーム３２２を回転させるモータに設けられたエンコーダなどの専用の検出センサ６５による検出結果に基づいて割り出される。動作機構の状態は、例えば上記の直動装置やモータに給電された電流値が含まれる。上記の電流値は、各種動作の実行中の負荷に応じて変動する。 「The“ status of the assistance device ”included in the log data M1 may be the status of the movable unit (elevating unit 31, swing unit 32) or the status of the operating mechanism (linear motion device, motor, etc.) in the drive device 30. The state of the movable unit includes, for example, the vertical position of the elevating unit 31 and the angle of the swing unit 32. These are determined based on the detection results of a dedicated detection sensor 65 such as a linear scale provided in a linear motion device for moving the elevating unit 31 up and down, and an encoder provided in a motor for rotating the arm 322. The state of the operation mechanism includes, for example, a current value supplied to the linear motion device or the motor. The above current value fluctuates according to the load during execution of various operations.
　また、ログデータＭ１に含まれる「介助装置の状態」は、被介助者Ｈを支持する支持部材４０が被介助者Ｈから受ける荷重としてもよい。支持部材４０が被介助者Ｈから受ける荷重は、被介助者Ｈの体重や脚力、被介助者Ｈの姿勢などに応じて変動する。支持部材４０が被介助者Ｈから受ける荷重は、例えば揺動本体３２１と胴体支持部４１との間に設けられたロードセルなどの専用の検出センサ６５による検出結果、または揺動部３２を回転させるモータに供給された電流値に基づいて割り出される。 The “state of the assisting device” included in the log data M1 may be a load received by the support member 40 supporting the assisted person H from the assisted person H. The load that the support member 40 receives from the assisted person H varies according to the weight and leg strength of the assisted person H, the posture of the assisted person H, and the like. The load received by the support member 40 from the care receiver H is, for example, a detection result of a dedicated detection sensor 65 such as a load cell provided between the swing main body 321 and the body support portion 41, or causes the swing portion 32 to rotate. It is determined based on the current value supplied to the motor.
　本実施形態において、被介助者Ｈおよび介助者の声音を検出する音声センサ６６が介助装置１０に設けられる。音声センサ６６は、例えば介助装置１０の支持部材４０の背面側に設けられる。音声センサ６６は、被介助者Ｈおよび介助者が発声した声音を検出する。音声センサ６６による声音の検出については、種々の方法を採用し得る。例えば、予め記憶された声紋と照合することにより検出する方法、テキスト化した音声から人物を特定する方法などが適用される。 In the present embodiment, the assistance device 10 is provided with a voice sensor 66 that detects the voice of the care recipient H and the care recipient. The voice sensor 66 is provided, for example, on the back side of the support member 40 of the assistance device 10. The voice sensor 66 detects the care recipient H and a voice uttered by the helper. Various methods can be adopted for the detection of the voice sound by the voice sensor 66. For example, a method of detecting by comparing with a voiceprint stored in advance, a method of specifying a person from a text voice, and the like are applied.
　ログデータＭ１に含まれる「介助装置の状態」は、各種動作の実行時における介助装置１０の位置としてもよい。介助装置１０は、被介助者Ｈを搭乗させた状態で、居室や浴室、リハビリ室、トイレ室などの複数の位置に移動され得る。介助装置１０の位置は、例えば各位置に設置された通知デバイスが発信する信号に基づいて割り出される。また、介助装置１０の位置は、介助装置１０に設けられた加速度センサやＧＰＳ装置による位置の検出結果に基づいて割り出されるようにしてもよい。 The “status of the assistance device” included in the log data M1 may be the position of the assistance device 10 at the time of executing various operations. The assistance device 10 can be moved to a plurality of positions, such as a living room, a bathroom, a rehabilitation room, and a toilet room, with the care recipient H on board. The position of the assistance device 10 is determined based on, for example, a signal transmitted from a notification device installed at each position. In addition, the position of the assistance device 10 may be determined based on a result of detecting a position by an acceleration sensor or a GPS device provided in the assistance device 10.
　ログデータＭ１に含まれる「識別情報」とは、介助装置１０が使用された際の被介助者Ｈおよび介助者を特定する情報であり、各種動作に関連付けて記録される。介助装置１０が被介助者Ｈにより操作される場合には、被介助者Ｈと操作者が同一として記録される。本実施形態において、識別情報は、介助装置１０に設けられた音声センサ６６による検出結果に基づいて、介助装置１０が使用された際の被介助者および介助者を特定される。なお、識別情報は、例えば被介助者Ｈや介助者の衣服に設けられた通知デバイスが発信する信号に基づいて特定されるようにしてもよい。 The “identification information” included in the log data M1 is information for specifying the care recipient H and the caregiver when the assistance device 10 is used, and is recorded in association with various operations. When the assisting device 10 is operated by the assisted person H, the assisted person H and the operator are recorded as the same. In the present embodiment, the identification information specifies the person to be assisted and the person to be assisted when the assisting device 10 is used, based on the detection result of the audio sensor 66 provided in the assisting device 10. The identification information may be specified based on a signal transmitted from, for example, the care receiver H or a notification device provided on the clothes of the care receiver.
　上記のログデータＭ１は、制御装置６０により生成および更新され、定期的にまたは要求などに応じて管理サーバ７０にアップロードされる。このとき、ログデータＭ１は、介助装置１０の識別情報（ＩＤ）と関連付けられて、管理サーバ７０に記憶される。 The above-described log data M1 is generated and updated by the control device 60, and is uploaded to the management server 70 periodically or as required. At this time, the log data M1 is stored in the management server 70 in association with the identification information (ID) of the assistance device 10.
　３．介助装置１０による移乗動作の補助
　上記のような構成からなる介助装置１０は、被介助者Ｈの移乗動作を補助する。上記の「移乗動作」とは、起立動作および着座動作の順で実行されたサイクル動作である。但し、移乗動作には、サイクル動作のうち、例えば可動部（昇降部３１、揺動部３２）の動作を確認するための試運転など被介助者Ｈの動作補助とは無関係の動作を含まない。 3. Assistance of Transfer Operation by Assist Device 10 The assist device 10 having the above configuration assists the transfer operation of the person H. The “transfer operation” is a cycle operation performed in the order of the standing operation and the sitting operation. However, the transfer operation does not include, among the cycle operations, an operation unrelated to assisting the operation of the care receiver H, such as a test run for confirming the operation of the movable unit (the lifting unit 31 and the swing unit 32).
　介助装置１０は、移乗動作において、被介助者Ｈの身体の一部（例えば、被介助者Ｈの上半身）を支持して、座位姿勢にある被介助者Ｈの起立動作を補助した後に方向転換を行い、別の位置に再び着座するように着座動作を補助する。移乗動作は、例えば居室内においてベッドと車椅子との間の移乗や、居室のベッドからトイレ室の便器との間の移乗などを目的として実行される。 In the transfer operation, the assisting device 10 supports a part of the body of the assisted person H (for example, the upper body of the assisted person H), and assists the assisted person H in the sitting posture to stand up and then change the direction. Is performed to assist the sitting operation so as to be seated again at another position. The transfer operation is executed for the purpose of, for example, transferring between a bed and a wheelchair in a living room, transferring from a bed in a living room to a toilet in a toilet room, and the like.
　ここで、胴体支持部４１のうち胴体に接触する部位の上端を基準位置Ｐｓとする。図２の太線は、被介助者Ｈの移乗動作のうち起立動作および着座動作の実行中における基準位置Ｐｓの移動軌跡Ｔｄを示す。つまり、制御装置６０は、基準位置Ｐｓが図２に示す移動軌跡Ｔｄに沿って移動するように、昇降部３１の上下動および揺動部３２の旋回動を協調させて支持部材４０の移動を制御する。 Here, the upper end of the part of the body supporting portion 41 that contacts the body is defined as the reference position Ps. The bold line in FIG. 2 indicates the movement trajectory Td of the reference position Ps during the execution of the standing operation and the sitting operation in the transfer operation of the care recipient H. That is, the control device 60 controls the movement of the support member 40 by coordinating the vertical movement of the lifting / lowering part 31 and the turning movement of the swing part 32 so that the reference position Ps moves along the movement trajectory Td shown in FIG. Control.
　なお、実際の移乗動作においては、上記のような起立動作および着座動作は、被介助者Ｈの姿勢と支持部材４０の状態（位置、角度）を介助者が常時確認することから、起立ボタン５１や着座ボタン５２が複数回に亘って押下されることがある。また、介助装置１０への被介助者Ｈの搭乗時には、被介助者Ｈに対して介助装置１０が位置決めされた後に、支持部材４０の高さを調整するために上昇ボタン５３または下降ボタン５４が複数回に亘って押下されることがある。また、移乗動作の最終段階において、介助装置１０から被介助者Ｈが降りるときにも同様に、支持部材４０の高さを調整するために上昇ボタン５３または下降ボタン５４が複数回に亘って押下されることがある。 In the actual transfer operation, the standing operation and the sitting operation as described above are performed by the caregiver who constantly checks the posture of the care receiver H and the state (position and angle) of the support member 40. And the seating button 52 may be pressed a plurality of times. Further, when the assisted person H is boarded on the assisted device 10, after the assisted device 10 is positioned with respect to the assisted person H, the ascending button 53 or the descending button 54 is used to adjust the height of the support member 40. It may be pressed several times. Similarly, at the final stage of the transfer operation, when the care receiver H gets off the assistance device 10, the up button 53 or the down button 54 is pressed a plurality of times to adjust the height of the support member 40. May be done.
　４．管理サーバ７０の構成
　管理サーバ７０は、クラウドサーバであり、複数のクライアント（例えば、複数の介助装置１０や複数の管理装置８０）とインターネットを介して通信可能に接続される。管理サーバ７０は、複数の介助装置１０からアップロードされるログデータＭ１をそれぞれ記憶する。また、管理サーバ７０は、管理装置８０の要求に応じて、所定の介助装置１０において記録されたログデータＭ１を管理装置８０に送信する。 4. Configuration of Management Server 70 The management server 70 is a cloud server, and is communicably connected to a plurality of clients (for example, a plurality of assistance devices 10 and a plurality of management devices 80) via the Internet. The management server 70 stores log data M1 uploaded from the plurality of assistance devices 10, respectively. Further, the management server 70 transmits the log data M1 recorded in the predetermined assistance device 10 to the management device 80 in response to a request from the management device 80.
　なお、管理サーバ７０は、所定の介助装置１０に係るログデータＭ１のうち、例えば要求に応じた一部のみを管理装置８０に送信する。具体的には、管理サーバ７０は、所定の介助装置１０が稼働した全期間に亘るログデータＭ１のうち所定期間に記録された一部を管理装置８０に送信してもよい。その他に、管理サーバ７０は、検出センサ６５の検出値や識別情報など一部の情報を除外した状態で管理装置８０に送信してもよい。これにより、管理装置８０は、必要な情報のみを管理サーバ７０から適宜ダウンロードすることができる。 The management server 70 transmits, for example, only a part of the log data M1 related to the predetermined assistance device 10 to the management device 80 in response to the request. Specifically, the management server 70 may transmit, to the management device 80, a part of the log data M1 recorded in the predetermined period of the log data M1 over the entire period in which the predetermined assistance device 10 operates. Alternatively, the management server 70 may transmit the information to the management device 80 with some information such as the detection value of the detection sensor 65 and identification information excluded. Thus, the management device 80 can appropriately download only necessary information from the management server 70.
　５．管理装置８０の構成
　管理装置８０は、介助装置１０を管理対象とし、取得したログデータＭ１に基づいて種々の情報などを提供する。管理装置８０は、例えば介助装置１０が導入された施設に設置されたパーソナルコンピュータや、携帯端末（スマートフォン、タブレット端末）などの端末装置である。本実施形態において、管理装置８０は、表示装置８１、記憶装置８２、および解析部８３を備える。 5. Configuration of Management Device 80 The management device 80 manages the assistance device 10 and provides various information based on the acquired log data M1. The management device 80 is a terminal device such as a personal computer or a mobile terminal (smartphone, tablet terminal) installed in a facility where the assistance device 10 is installed. In the present embodiment, the management device 80 includes a display device 81, a storage device 82, and an analysis unit 83.
　表示装置８１は、解析部８３により生成された各種情報を表示する。表示装置８１は、例えば各種情報の閲覧者による操作を受け付けるタッチスクリーンとしてもよい。本実施形態において、表示装置８１は、解析部８３により生成された使用実績データＭ２および統計データＭ４を表示する。上記の「使用実績データＭ２」および「統計データＭ４」の詳細については後述する。 The display device 81 displays various information generated by the analysis unit 83. The display device 81 may be, for example, a touch screen that receives an operation by a viewer of various information. In the present embodiment, the display device 81 displays the usage result data M2 and the statistical data M4 generated by the analysis unit 83. Details of the above-mentioned "use result data M2" and "statistical data M4" will be described later.
　記憶装置８２は、ハードディスク装置などの光学ドライブ装置、またはフラッシュメモリなどにより構成される。この記憶装置８２には、管理サーバ７０から取得したログデータＭ１、解析部８３により生成される使用実績データＭ２、複数の被介助者Ｈごとの体格および要介助水準を示す被介助者情報Ｍ３、および解析部８３により生成される統計データＭ４が記憶される。 The storage device 82 is configured by an optical drive device such as a hard disk device or a flash memory. In this storage device 82, log data M1 acquired from the management server 70, usage record data M2 generated by the analysis unit 83, care recipient information M3 indicating the physique and the level of assistance required for each of the plurality of care recipients H, And the statistical data M4 generated by the analyzing unit 83.
　解析部８３は、ログデータＭ１に対して種々の解析処理を実行する。本実施形態において、解析部８３による解析処理には、ログデータＭ１における移乗動作の検出処理、および使用実績データＭ２の生成処理が含まれる。ここで、ログデータＭ１に記録されている動作履歴や操作履歴には、実際に移乗動作を実行するためのものの他に、被介助者Ｈが搭乗していない状態での試運転などに係る動作や操作も含まれる。そこで、解析部８３は、移乗動作の検出処理を実行する構成としている。 The analysis unit 83 executes various analysis processes on the log data M1. In the present embodiment, the analysis process performed by the analysis unit 83 includes a process of detecting a transfer operation in the log data M1 and a process of generating use result data M2. Here, the operation history and the operation history recorded in the log data M1 include, in addition to the data for actually executing the transfer operation, the operations related to the test run and the like when the care recipient H is not on board. Operation is also included. Therefore, the analysis unit 83 is configured to execute a transfer operation detection process.
　具体的には、解析部８３は、先ずログデータＭ１において起立動作および着座動作の順で実行されたサイクル動作を検出する。このとき、サイクル動作には、起立動作および着座動作の少なくとも一方に関連して一連で実行された調整動作を含めてもよい。上記の調整動作には、例えば起立動作に際して実行された支持部材４０の昇降動作、被介助者Ｈの乗降に際して実行された支持部材４０の旋回動作などが含まれ得る。 Specifically, the analysis unit 83 first detects a cycle operation executed in the order of the standing operation and the sitting operation in the log data M1. At this time, the cycle operation may include an adjustment operation executed in series in connection with at least one of the standing operation and the sitting operation. The above-described adjustment operation may include, for example, an elevating operation of the support member 40 executed at the time of the standing operation, a turning operation of the support member 40 executed at the time of getting on and off the care recipient H, and the like.
　そして、解析部８３は、検出されたサイクル動作が被介助者Ｈを移乗させた移乗動作であるか否かをログデータＭ１に基づいて判定する。このような判定処理を行うのは、検出されたサイクル動作には試運転などが含まれる可能性があるためである。判定処理は、操作装置５０の各種ボタンの押下順序や押下時間、検出センサ６５の検出結果に基づいて行うようにしてもよい。本実施形態において、解析部８３は、先ずサイクル動作における起立動作と着座動作の間隔、詳細には起立動作の終了時刻から着座動作の開始時刻までの時間（以下、「中間時間」と称する）を算出する。次に、解析部８３は、中間時間が規定期間内である場合にサイクル動作が移乗動作であると判定する。 {Circle around (7)} Then, the analysis unit 83 determines whether or not the detected cycle operation is a transfer operation in which the care recipient H is transferred, based on the log data M1. The reason why such a determination process is performed is that the detected cycle operation may include a test run or the like. The determination process may be performed based on the pressing order and pressing time of various buttons of the operation device 50, and the detection result of the detection sensor 65. In the present embodiment, the analysis unit 83 first determines the interval between the standing operation and the sitting operation in the cycle operation, specifically, the time from the end time of the standing operation to the start time of the sitting operation (hereinafter, referred to as “intermediate time”). calculate. Next, the analysis unit 83 determines that the cycle operation is a transfer operation when the intermediate time is within the specified period.
　ここで、介助装置１０が試運転ではなく、介助装置１０に被介助者Ｈが搭乗し何らかの目的で移乗動作が実行された場合には、起立動作が終了してから方向転換や移動、被介助者Ｈの脱衣など移乗動作の目的に応じた処理がなされる。結果として、上記処理の所要時間だけ中間時間が発生する。一方で、中間時間が過剰に長い場合（中間時間が規定期間を超える場合）には、例えば介助装置１０が保管状態とされていたと判断できる。そこで、解析部８３は、上記のように中間時間の長さに基づいてサイクル動作が移乗動作であるか否かを判定する。 Here, when the assisting device 10 is not a trial run, but the assisted person H gets on the assisted device 10 and the transfer operation is performed for any purpose, the turning operation, the movement, and the assisted person are performed after the standing operation is completed. Processing corresponding to the purpose of the transfer operation such as undressing of H is performed. As a result, an intermediate time occurs for the time required for the above processing. On the other hand, when the intermediate time is excessively long (when the intermediate time exceeds the specified period), it can be determined that, for example, the assisting device 10 is in the storage state. Thus, the analysis unit 83 determines whether the cycle operation is a transfer operation based on the length of the intermediate time as described above.
　また、解析部８３は、図４の表１に示すように、移乗動作の実行回数および所要時間、被介助者Ｈが起立姿勢を維持された時間、重負担動作の実行回数および所要時間を含む使用実績データＭ２を生成する。移乗動作の所要時間は、所定期間における累計である。また、被介助者Ｈが起立姿勢を維持された時間とは、移乗動作における中間時間に相当する。 In addition, as shown in Table 1 of FIG. 4, the analysis unit 83 includes the number of times the transfer operation is performed and the required time, the time during which the care recipient H is in the standing posture, the number of times the heavy load operation is performed, and the required time. The usage result data M2 is generated. The time required for the transfer operation is a cumulative total for a predetermined period. In addition, the time during which the care recipient H is maintained in the standing posture corresponds to an intermediate time in the transfer operation.
　上記の「重負担動作」とは、介助者が介助装置１０を使用せずに被介助者Ｈの起立動作および着座動作を補助した場合に介助者の重負担となる動作である。例えば、重負担動作には、被介助者Ｈの体重の大半を介助者が保持する必要がある動作や、被介助者Ｈの起立姿勢を所定時間に亘って維持する動作が含まれる。重負担動作は、介助装置１０を使用しない場合には、例えば力のある介助者を要することがある。 The “heavy load operation” is an operation that places a heavy burden on the caregiver when the caregiver assists the person H in standing up and sitting without using the assistance device 10. For example, the heavy load operation includes an operation in which the caregiver needs to hold most of the weight of the assisted person H and an operation in which the assisted person H maintains the standing posture for a predetermined time. The heavy-duty operation may require, for example, a powerful helper when not using the assistance device 10.
　解析部８３は、重負担動作をログデータＭ１から検出し、重負担動作の実行回数および所要時間を含む使用実績データＭ２を生成する。ここで、介助装置１０が補助した移乗動作であっても被介助者Ｈの体格や要介助水準によっては重負担動作となる場合とならない場合とがある。そこで、解析部８３は、複数の被介助者Ｈごとの体格および要介助水準を示す被介助者情報Ｍ３に基づいて重負担動作をログデータＭ１から検出する。上記の被介助者情報Ｍ３は、図４の表２に示すように、被介助者Ｈごとの体格および要介助水準を示す。 The analysis unit 83 detects the heavy load operation from the log data M1, and generates use result data M2 including the number of times of the heavy load operation and the required time. Here, the transfer operation assisted by the assisting device 10 may or may not be a heavy load operation depending on the physique and the level of assistance required of the assisted person H. Therefore, the analysis unit 83 detects a heavy load operation from the log data M1 based on the care recipient information M3 indicating the physique and the level of assistance required for each of the plurality of care recipients H. As shown in Table 2 in FIG. 4, the care recipient information M3 indicates the physique and the level of assistance required for each care recipient H.
　被介助者情報Ｍ３における被介助者Ｈの体格は、例えば被介助者Ｈの身長、体重、胴回り寸法などが含まれ得る。これは、例えば被介助者Ｈの身長が高かったり、体重が一定以上であったりする場合には、介助者による移乗動作が重負担となるとの考えに基づくものである。また、被介助者情報Ｍ３における被介助者Ｈの要介助水準は、例えば被介助者Ｈの脚力、握力、円背の度合いなどの評価項目に基づいて、段階的な数値により設定される。これは、例えば、被介助者Ｈの要介助水準が高い場合には、同様の体格であっても介助者による移乗動作が重負担となるとの考えに基づくものである。 The physique of the care recipient H in the care recipient information M3 may include, for example, the height, weight, and waist size of the care recipient H. This is based on the idea that when the height of the care receiver H is high or the weight is equal to or more than a certain value, the transfer operation by the helper becomes heavy. In addition, the level of assistance required of the assisted person H in the assisted person information M3 is set by a stepwise numerical value based on evaluation items such as the strength of the assisted person H, the grip strength, and the height of the circle. This is based on the idea that, for example, when the care-requiring level of the care receiver H is high, the transfer operation by the helper is burdensome even with the same physique.
　なお、解析部８３は、ログデータＭ１から重負担動作を検出する際に、上記のように被介助者情報Ｍ３に基づく他に、種々の方法を採用し得る。例えば、解析部８３は、検出センサ６５による検出結果に基づいて重負担動作をログデータＭ１から検出してもよい。このような構成において、解析部８３は、例えば介助装置１０の状態を検出するためのロードセルや電流計などの検出センサ６５による検出結果に基づいて、支持部材４０が被介助者Ｈから受ける荷重の大きさを算出する。そして、解析部８３は、移乗動作における荷重の大きさに基づいて、その移乗動作が重負担動作であるか否かを判定する。 Note that the analysis unit 83 can employ various methods other than the above based on the care recipient information M3 when detecting a heavy load operation from the log data M1. For example, the analysis unit 83 may detect a heavy load operation from the log data M1 based on a detection result by the detection sensor 65. In such a configuration, for example, the analysis unit 83 detects the load received by the support member 40 from the care receiver H based on the detection result by the detection sensor 65 such as a load cell for detecting the state of the assistance device 10 or an ammeter. Calculate the size. Then, the analyzing unit 83 determines whether or not the transfer operation is a heavy load operation based on the magnitude of the load in the transfer operation.
　また、解析部８３は、被介助者Ｈの姿勢および当該姿勢の維持時間の関係に基づいて重負担動作をログデータＭ１から検出してもよい。上記のように、重負担動作には、被介助者Ｈの起立姿勢を所定時間に亘って維持する動作が含まれる。そこで、解析部８３は、生成した使用実績データＭ２に含まれる「被介助者Ｈが起立姿勢を維持された時間」に基づいて、その移乗動作が重負担動作であるか否かを判定する。 The analysis unit 83 may detect the heavy load operation from the log data M1 based on the relationship between the position of the care recipient H and the maintenance time of the position. As described above, the heavy load operation includes an operation of maintaining the caretaker H's standing posture for a predetermined time. Therefore, the analyzing unit 83 determines whether or not the transfer operation is a heavy load operation based on “time during which the care recipient H has been in the standing posture” included in the generated usage result data M2.
　本実施形態において、解析部８３は、図４の表３に示すように、所定の期間ごとの介助装置１０の使用回数および使用時間の少なくとも一方の統計値を示す統計データＭ４を、使用実績データＭ２に基づいて生成する。上記の「所定の期間」とは、管理者が任意に設定できる介助装置１０の使用期間であって、例えば１週間や数週間、１ヶ月などの期間が設定され得る。解析部８３は、上記の所定の期間における介助装置１０の使用回数および使用時間として、例えば移乗動作の実行回数および所要時間を算出して、統計データＭ４における統計値とする。 In the present embodiment, as shown in Table 3 of FIG. 4, the analysis unit 83 converts the statistical data M4 indicating at least one statistical value of the number of times of use and the time of use of the assisting device 10 for each predetermined period into use result data. Generated based on M2. The “predetermined period” is a period of use of the assisting device 10 that can be arbitrarily set by the administrator, and may be set to a period such as one week, several weeks, or one month. The analyzing unit 83 calculates, for example, the number of times the transfer operation is performed and the required time as the number of times and the time of use of the assistance device 10 during the above-described predetermined period, and sets the calculated number as the statistical value in the statistical data M4.
　また、本実施形態において、解析部８３は、所定の期間における介助装置１０の使用可能性を含む統計データＭ４を生成する。上記の介助装置１０の「使用可能性」とは、現在から所定の期間、例えば１週間における特定の曜日や時間帯において使用者が介助装置１０を不使用状態にあり使用可能であると推定される確率に相当する。具体的には、解析部８３は、所定の期間ごとの統計値をそれぞれ算出したところ、特定の曜日や時間帯において介助装置１０の使用頻度の偏りの有無を認識する。 In addition, in the present embodiment, the analysis unit 83 generates the statistical data M4 including the availability of the assistance device 10 during a predetermined period. The “usability” of the assistance device 10 is assumed to be that the user is in a non-use state and can use the assistance device 10 for a predetermined period from now, for example, on a specific day of the week or time period in one week. Equivalent to the probability of Specifically, after calculating the statistical value for each predetermined period, the analysis unit 83 recognizes whether or not the usage frequency of the assisting device 10 is biased on a specific day of the week or time period.
　そして、解析部８３は、介助装置１０の今後の使用において、使用頻度が低いと推定される曜日や時間帯について、使用可能性が高いとして統計データＭ４に含ませる。一方で、解析部８３は、介助装置１０の今後の使用において、使用頻度が高いと推定される曜日や時間帯について、使用可能性が低いとして統計データＭ４に含ませる。なお、所定の期間については管理者等が任意に設定できる。このような構成によると、将来的に介助装置１０が特定の日時において休止しており使用可能な状態にあるだろうことが示され、介助装置１０の有効利用化を図ることができる。 {Circle around (7)} Then, in the future use of the assisting device 10, the analysis unit 83 includes in the statistical data M4 that the possibility of use is high for the day of the week or the time zone estimated to be used less frequently. On the other hand, in the future use of the assisting device 10, the analysis unit 83 includes, in the statistical data M4, the possibility that the use frequency is high for the day of the week or the time zone that is estimated to be high. The predetermined period can be arbitrarily set by an administrator or the like. According to such a configuration, it is shown that the assisting device 10 will be inactive at a specific date and time in the future and will be in a usable state, and the effective use of the assisting device 10 can be achieved.
　また、本実施形態において、解析部８３は、被介助者Ｈまたは介助者ごとの介助装置１０の使用回数および使用時間の少なくとも一方の統計値を示す統計データＭ４を、使用実績データＭ２に基づいて生成する。つまり、解析部８３は、ログデータＭ１に含まれる識別情報に基づいて、複数の被介助者Ｈごとに、および複数の介助者ごとに介助装置１０が何回使用されたか、および使用に係る所要時間の累計を統計値として統計データＭ４に記録する。 In the present embodiment, the analysis unit 83 generates statistical data M4 indicating at least one of the number of times of use and the time of use of the assisting device 10 for each of the care recipient H or the caregiver based on the usage record data M2. Generate. That is, the analysis unit 83 determines, based on the identification information included in the log data M1, how many times the assisting device 10 has been used for each of the plurality of assisted persons H and for each of the plurality of assisted persons, and The cumulative time is recorded as a statistical value in the statistical data M4.
　このような構成によると、管理者等は、上記のような統計データＭ４を表示され、被介助者Ｈごと、または介助者ごとの使用実績を容易に認識することができる。これにより、従来では例えば特定の時間帯ごとに誰が使用したかの記録等に基づいて使用実績を割り出す必要があったのに対して、より精度よく各者の使用実績を認識できる。また、介助者情報Ｍ３と照合することにより、どのような体格または要介助水準の被介助者Ｈに介助装置１０を使用できたかといった実績を把握することができ、介助装置１０の有効利用化を図ることができる。 According to such a configuration, the administrator or the like is displayed with the statistical data M4 as described above, and can easily recognize the usage record of each care receiver H or each caregiver. As a result, conventionally, for example, it has been necessary to determine the use record based on a record of who used it for each specific time zone, but the use record of each person can be recognized more accurately. In addition, by collating with the helper information M3, it is possible to grasp the actual result such as what kind of physique or the required level of the helper H can use the helper device 10, and the effective use of the helper device 10 can be realized. Can be planned.
　６．管理装置８０による介助装置１０の管理処理
　管理装置８０による介助装置１０の管理処理について、図３－図５を参照して説明する。ここで、介助装置１０の管理処理は、例えば介助システム１の管理者の任意で、または定期的な処理として実行され得る。なお、管理サーバ７０には、管理処理の実行に際して予め所定の介助装置１０からログデータＭ１が送信され、所定期間に亘る動作履歴および操作履歴を含むログデータＭ１が記憶されているものとする。 6. Management Process of Assistance Device 10 by Management Device 80 The management process of the assistance device 10 by the management device 80 will be described with reference to FIGS. Here, the management process of the assistance device 10 can be performed, for example, by the administrator of the assistance system 1 or as a periodic process. It is assumed that log data M1 is transmitted from a predetermined assistance device 10 in advance to the management server 70 when the management process is executed, and log data M1 including an operation history and an operation history over a predetermined period is stored.
