The group management device 10 assigns a landing call to each of the plurality of elevator units 5, for example. The elevator 3 may include both an elevator unit 5 managed by the group management device 10 and an unmanaged elevator unit 5.
　エレベーターユニット５の制御盤７、またはエレベーター３の群管理装置１０は、エレベーター制御部の例である。エレベーター制御部は、エレベーター３の動作を制御する装置などである。この例において、エレベーター３は、複数のエレベーター制御部を備えている。エレベーター制御部は、エレベーター３の複数の状態データを、例えばエレベーター３に設けられる図示されないセンサーなどから逐次取得する。複数の状態データの各々は、データが測定された時刻、およびデータを測定したセンサーを特定する情報などを含んでもよい。 The control panel 7 of the elevator unit 5 or the group management device 10 of the elevator 3 is an example of the elevator control unit. The elevator control unit is a device or the like that controls the operation of the elevator 3. In this example, the elevator 3 includes a plurality of elevator control units.

Each of the plurality of state data may include the time when the data was measured, information identifying the sensor that measured the data, and the like.
　ここで、状態データは、エレベーター３の状態を表すデータである。状態データは、例えば動作データ、または呼びデータを含む。動作データは、エレベーター３の動作の状況を表すデータである。動作データは、例えば走行状態、ドアの開閉状態、かご負荷、またはかご位置を含む。走行状態は、例えばかご６の走行の速度または方向などの情報を含む。ドアの開閉状態は、例えばかごドア８または乗場ドアが開いているか否かなどの情報を含む。かご負荷は、例えば秤装置９によって測定されるかご６の積載重量などの情報を含む。かご位置は、例えば昇降路におけるかご６の高さなどの情報を含む。呼びデータは、呼びの状況を表すデータである。呼びデータは、例えばエレベーター３の呼びの登録、呼びの割当て、または呼びへの応答のデータを含む。呼びの登録は、例えば登録された時刻、登録されたかご６を特定する情報、または対応する階床などの情報を含む。呼びの割当は、例えば割り当てられた時刻、割り当てられたかご６を特定する情報、または対応する階床などの情報を含む。呼びへの応答は、例えば呼びが対応する階床に停止した時刻、応答したかご６を特定する情報、または応答した階床などの情報を含む。 Here, the state data is data representing the state of the elevator 3.

　エッジサーバー４は、第１通信路１１を通じて複数のエレベーター制御部の各々に接続される。第１通信路１１は、局所的な通信路である。ここで、局所的な通信路は、例えば複数の都市または地域などにわたらない通信路である。第１通信路１１は、例えばエレベーター３が設けられる建築物に設けられる通信路である。あるいは、当該建築物が複数の建築物を有する施設の一部である場合に、第１通信路１１は、例えば当該施設に設けられる通信路であってもよい。第１通信路１１は、有線通信または無線通信による直接的な通信路であってもよい。あるいは、第１通信路１１は、例えばＬＡＮなどの局所的なネットワークを経由する通信路であってもよい。この例において、第１通信路１１は、エレベーターシステム２の内部の通信路である。なお、第１通信路１１は、建築物においてエレベーターシステム２の他のシステムと共有されるＬＡＮなどの局所的なネットワークを経由する通信路であってもよい。 The edge server 4 is connected to each of the plurality of elevator control units through the first communication path 11. The first communication path 11 is a local communication path. Here, the local communication path is, for example, a communication path that does not span a plurality of cities or regions. The first communication path 11 is, for example, a communication path provided in a building in which an elevator 3 is provided. Alternatively, when the building is a part of a facility having a plurality of buildings, the first communication path 11 may be, for example, a communication path provided in the facility. The first communication path 11 may be a direct communication path by wired communication or wireless communication. Alternatively, the first communication path 11 may be a communication path that goes through a local network such as a LAN. In this example, the first communication path 11 is a communication path inside the elevator system 2. The first communication path 11 may be a communication path via a local network such as a LAN shared with another system of the elevator system 2 in the building.
　遠隔監視システム１は、監視端末１２を備える。監視端末１２は、複数のエレベーターシステム２の各々を遠隔監視する端末装置である。監視端末１２は、例えば監視センターに設けられる。監視センターは、複数のエレベーターシステム２の各々を遠隔監視する拠点である。監視センターは、例えば複数のエレベーターシステム２の各々が設けられる建築物から地理的に離れた遠隔地にある拠点である。監視端末１２は、第２通信路１３を通じて、複数のエレベーターシステム２の各々のエッジサーバー４に接続される。第２通信路１３は、広域的な通信路である。ここで、広域的な通信路は、例えば複数の都市または地域などにわたる通信路である。第２通信路１３は、例えばインターネット１４などの広域的なネットワークを経由する通信路である。第２通信路１３は、広域的なイントラネット、またはＶＰＮ（Ｖｉｒｔｕａｌ　Ｐｒｉｖａｔｅ　Ｎｅｔｗｏｒｋ）などのネットワークを経由する通信路であってもよい。この例において、第２通信路１３は、エレベーターシステム２の外部を含む通信路である。 The remote monitoring system 1 includes a monitoring terminal 12. The monitoring terminal 12 is a terminal device that remotely monitors each of the plurality of elevator systems 2. The monitoring terminal 12 is provided in, for example, a monitoring center. The monitoring center is a base for remotely monitoring each of the plurality of elevator systems 2. The monitoring center is, for example, a base located in a remote location geographically separated from the building in which each of the plurality of elevator systems 2 is provided. The monitoring terminal 12 is connected to each edge server 4 of the plurality of elevator systems 2 through the second communication path 13. The second communication path 13 is a wide area communication path. Here, the wide area communication path is, for example, a communication path that spans a plurality of cities or regions. The second communication path 13 is a communication path that goes through a wide area network such as the Internet 14. The second communication path 13 may be a communication path via a wide-area intranet or a network such as a VPN (Virtual Private Network). In this example, the second communication path 13 is a communication path including the outside of the elevator system 2.
　この例において、第２通信路１３を経由する通信の遅延は、第１通信路１１を経由する通信の遅延より大きい。また、この例において、第２通信路１３を経由する通信の距離は、第１通信路１１を経由する通信の距離より長い。ここで、通信の距離は、例えばホップ数などである。 In this example, the delay of communication via the second communication path 13 is larger than the delay of communication via the first communication path 11. Further, in this example, the communication distance via the second communication path 13 is longer than the communication distance via the first communication path 11. Here, the communication distance is, for example, the number of hops.
　複数のエレベーターシステム２の各々において、エッジサーバー４は、バッファ１５と、解析部１６と、記憶部１７と、を備える。 In each of the plurality of elevator systems 2, the edge server 4 includes a buffer 15, an analysis unit 16, and a storage unit 17.
　バッファ１５は、複数の状態データを一時的に蓄積する部分である。バッファ１５は、エレベーター制御部から複数の状態データを逐次取得する。バッファ１５は、エレベーター制御部または通信を中継する装置に逐次問い合わせることで状態データを取得してもよい。あるいは、バッファ１５は、エレベーター制御部から逐次出力される状態データを受け入れることで状態データを取得してもよい。バッファ１５は、蓄積しているデータの容量が予め定められた記憶容量を超える場合に古いデータを上書きすることによってデータを一時的に蓄積してもよい。あるいは、バッファ１５は、予め定められた期間より古いデータを消去することによってデータを一時的に蓄積してもよい。 The buffer 15 is a part that temporarily stores a plurality of state data. The buffer 15 sequentially acquires a plurality of state data from the elevator control unit. The buffer 15 may acquire state data by sequentially inquiring the elevator control unit or the device that relays communication. Alternatively, the buffer 15 may acquire the state data by receiving the state data sequentially output from the elevator control unit. When the capacity of the stored data exceeds a predetermined storage capacity, the buffer 15 may temporarily store the data by overwriting the old data. Alternatively, the buffer 15 may temporarily store data by erasing data older than a predetermined period.
　解析部１６は、バッファ１５に蓄積された複数の状態データに基づいて解析を行う部分である。解析部１６は、例えば予め定められた期間ごとに、当該期間の間にバッファ１５に蓄積された複数の状態データの解析を行う。あるいは、解析部１６は、バッファ１５に蓄積された状態データの容量が予め定められた容量を超えるときに、バッファ１５に蓄積された複数の状態データの解析を行ってもよい。あるいは、解析部１６は、これらの期間および容量の条件を組み合わせた条件によって複数の状態データの解析を行ってもよい。解析部１６は、第２通信路１３を通じて監視端末１２に解析結果を出力する。 The analysis unit 16 is a part that performs analysis based on a plurality of state data stored in the buffer 15. The analysis unit 16 analyzes a plurality of state data accumulated in the buffer 15 during the period, for example, for each predetermined period. Alternatively, the analysis unit 16 may analyze a plurality of state data stored in the buffer 15 when the capacity of the state data stored in the buffer 15 exceeds a predetermined capacity. Alternatively, the analysis unit 16 may analyze a plurality of state data under a condition that combines these period and capacity conditions. The analysis unit 16 outputs the analysis result to the monitoring terminal 12 through the second communication path 13.
　解析部１６による解析結果は、例えばエレベーター３のサービスの状態がわかるような結果である。解析部１６による解析結果は、例えばエレベーター３の乗客の待ち時間、乗客の乗車時間を含んでもよい。解析結果は、イベントの発生を表す情報を含んでもよい。解析結果は、解析結果が表すイベントの発生の回数を含んでもよい。解析結果が表すイベントは、例えばエレベーター３の乗客の待ち時間が予め設定された閾値を超えたこと、または、エレベーター３の満員通過が発生したことなどであってもよい。ここで、エレベーター３の満員通過は、乗車している乗客が満員であるために、乗場呼びが登録されている階床をかご６が通過するイベントである。 The analysis result by the analysis unit 16 is, for example, a result that shows the service status of the elevator 3. The analysis result by the analysis unit 16 may include, for example, the waiting time of the passengers of the elevator 3 and the boarding time of the passengers. The analysis result may include information indicating the occurrence of an event. The analysis result may include the number of occurrences of the event represented by the analysis result. The event represented by the analysis result may be, for example, that the waiting time of the passengers of the elevator 3 exceeds a preset threshold value, or that the elevator 3 is full. Here, the full passage of the elevator 3 is an event in which the car 6 passes through the floor where the landing call is registered because the passengers on board are full.
　記憶部１７は、解析部１６による解析結果を記憶する部分である。記憶部１７は、例えば解析部１６が監視端末１２に出力する解析結果を取得して記憶する。 The storage unit 17 is a part that stores the analysis result by the analysis unit 16. The storage unit 17 acquires and stores the analysis result output by the analysis unit 16 to the monitoring terminal 12, for example.
　この例において、バッファ１５は、解析部１６によって既に解析された状態データを記憶しない。例えば、バッファ１５は、解析部１６が解析を行ったときに、解析部１６によって既に解析された状態データを削除してもよい。あるいは、バッファ１５は、解析部１６によってまだ解析されていない状態データを上書きから保護し、解析部１６が解析を行ったときに既に解析された状態データの保護を解除してもよい。 In this example, the buffer 15 does not store the state data already analyzed by the analysis unit 16. For example, the buffer 15 may delete the state data already analyzed by the analysis unit 16 when the analysis unit 16 performs the analysis. Alternatively, the buffer 15 may protect the state data that has not yet been analyzed by the analysis unit 16 from overwriting, and may release the protection of the state data that has already been analyzed when the analysis unit 16 performs the analysis.
　解析部１６は、解析結果が指定イベントを表す場合に、当該指定イベントが発生した時刻を含む時間範囲に取得された状態データを当該解析結果に合わせて出力してもよい。指定イベントは、予め指定されたイベントである。指定イベントは、例えば、エレベーター３の乗客の待ち時間が予め設定された閾値を超える事象、または、エレベーター３の満員通過の事象である。また、指定イベントが発生した時刻を含む時間範囲は、例えば、イベントが発生した時刻より予め設定された時間だけ前の時刻から、イベントが発生した時刻より予め設定された時間だけ後の時刻までの間の範囲である。当該時間範囲は、指定イベントの種類ごとに予め設定されていてもよい。記憶部１７は、解析結果に合わせて出力された状態データを、当該解析結果と併せて記憶する。 When the analysis result represents a designated event, the analysis unit 16 may output the state data acquired in the time range including the time when the designated event occurs in accordance with the analysis result. The designated event is a pre-designated event. The designated event is, for example, an event in which the waiting time of passengers in the elevator 3 exceeds a preset threshold value, or an event in which the elevator 3 is full. The time range including the time when the specified event occurs is, for example, from the time before the time when the event occurs to the time before the preset time to the time after the time when the event occurs. The range between. The time range may be preset for each type of designated event. The storage unit 17 stores the state data output according to the analysis result together with the analysis result.
　続いて、図２を用いて、エレベーターシステム２の動作の例を説明する。
　図２は、実施の形態１に係るエレベーターシステムの動作の例を示すフローチャートである。 Subsequently, an example of the operation of the elevator system 2 will be described with reference to FIG.
FIG. 2 is a flowchart showing an example of the operation of the elevator system according to the first embodiment.
　ステップＳ１において、バッファ１５は、逐次取得される複数の情報データを蓄積する。その後、エレベーターシステム２の動作は、ステップＳ２に進む。 In step S1, the buffer 15 accumulates a plurality of information data to be sequentially acquired. After that, the operation of the elevator system 2 proceeds to step S2.
　ステップＳ２において、解析部１６は、以前に状態データの解析を行ってから、予め設定された時間が経過したかを判定する。ここで、例えば起動の直後など、以前に状態データの解析を行った時刻が記憶されていない場合において、解析部１６は、起動から予め設定された時間を経過したかを判定してもよい。判定結果がＮｏの場合に、エレベーターシステム２の動作は、ステップＳ１に進む。判定結果がＹｅｓの場合に、エレベーターシステム２の動作は、ステップＳ３に進む。 In step S2, the analysis unit 16 determines whether a preset time has elapsed since the state data was previously analyzed. Here, when the time when the state data was previously analyzed is not stored, for example, immediately after the start-up, the analysis unit 16 may determine whether or not a preset time has passed since the start-up. When the determination result is No, the operation of the elevator system 2 proceeds to step S1. When the determination result is Yes, the operation of the elevator system 2 proceeds to step S3.
　ステップＳ３において、解析部１６は、バッファ１５に一時的に蓄積された複数の状態データを解析する。その後、エレベーターシステム２の動作は、ステップＳ４に進む。 In step S3, the analysis unit 16 analyzes a plurality of state data temporarily stored in the buffer 15. After that, the operation of the elevator system 2 proceeds to step S4.
　ステップＳ４において、解析部１６は、状態データを解析した解析結果を監視端末１２に第２通信路１３を通じて出力する。その後、エレベーターシステム２の動作は、ステップＳ１に進む。 In step S4, the analysis unit 16 outputs the analysis result of analyzing the state data to the monitoring terminal 12 through the second communication path 13. After that, the operation of the elevator system 2 proceeds to step S1.
　以上に説明したように、実施の形態１に係るエレベーターシステム２は、エレベーター制御部と、エッジサーバー４と、を備える。エレベーター制御部は、エレベーター３の動作を制御する。エッジサーバー４は、局所的な第１通信路１１を通じてエレベーター制御部に接続される。エッジサーバー４は、広域的な第２通信路１３を通じて監視端末１２に接続される。エッジサーバー４は、バッファ１５と、解析部１６と、を備える。バッファ１５は、エレベーター制御部が逐次取得するエレベーターの複数の状態データを一時的に蓄積する。解析部１６は、バッファ１５に蓄積された複数の状態データに基づく解析結果を監視端末１２に出力する。 As described above, the elevator system 2 according to the first embodiment includes an elevator control unit and an edge server 4. The elevator control unit controls the operation of the elevator 3. The edge server 4 is connected to the elevator control unit through the local first communication path 11. The edge server 4 is connected to the monitoring terminal 12 through the wide area second communication path 13. The edge server 4 includes a buffer 15 and an analysis unit 16. The buffer 15 temporarily stores a plurality of elevator state data that are sequentially acquired by the elevator control unit. The analysis unit 16 outputs the analysis result based on the plurality of state data stored in the buffer 15 to the monitoring terminal 12.
　このように、取得された状態データの解析は、エッジサーバー４によって行われる。このため、エレベーターシステム２は、取得したすべての状態データを広域的な第２通信路１３において通信しなくても、遠隔監視システム１による遠隔監視を受けられる。これにより、遠隔監視において広域的な通信路の通信量を抑制できる。また、監視端末１２に接続される通信路における通信量が抑制されるので、通信の衝突などが抑制される。これにより、取得される状態データの量が増大しても、エレベーターシステム２は、遠隔監視における通信を効率的に行うことができる。 In this way, the analysis of the acquired state data is performed by the edge server 4. Therefore, the elevator system 2 can receive remote monitoring by the remote monitoring system 1 without having to communicate all the acquired state data in the wide area second communication path 13. As a result, it is possible to suppress the amount of communication over a wide area in remote monitoring. In addition, since the amount of communication in the communication path connected to the monitoring terminal 12 is suppressed, communication collisions and the like are suppressed. As a result, even if the amount of acquired state data increases, the elevator system 2 can efficiently perform communication in remote monitoring.
　また、エッジサーバー４は、記憶部１７を備える。記憶部１７は、解析部１６から出力される解析結果を記憶する。 Further, the edge server 4 includes a storage unit 17. The storage unit 17 stores the analysis result output from the analysis unit 16.
　エッジサーバー４において、状態データは、バッファ１５に一時的に記憶される。解析結果は、記憶部１７に記憶される。このため、記憶部１７は、取得されるすべての状態データを記憶する必要がない。これにより、取得される状態データの量が増大しても、エッジサーバー４の記憶容量の増大が抑制される。 In the edge server 4, the state data is temporarily stored in the buffer 15. The analysis result is stored in the storage unit 17. Therefore, the storage unit 17 does not need to store all the acquired state data. As a result, even if the amount of acquired state data increases, the increase in the storage capacity of the edge server 4 is suppressed.
　また、バッファ１５は、解析部１６によって既に解析された複数の状態データを記憶しない。 Further, the buffer 15 does not store a plurality of state data already analyzed by the analysis unit 16.
　これにより、バッファ１５は、解析を終えて不要となった状態データによって記憶容量が圧迫されない。これにより、取得される状態データの量が増大しても、バッファ１５の記憶容量の増大が抑制される。 As a result, the storage capacity of the buffer 15 is not squeezed by the state data that is no longer needed after the analysis. As a result, even if the amount of acquired state data increases, the increase in the storage capacity of the buffer 15 is suppressed.
　また、バッファ１５は、状態データとして、エレベーター３の走行状態、エレベーター３のドアの開閉状態、エレベーター３のかご負荷、またはエレベーター３のかご位置の少なくともいずれかを含むデータを蓄積する。解析部１６は、当該データに基づく解析結果を出力する。
　また、バッファ１５は、状態データとして、エレベーター３の呼びの登録、呼びの割当て、または呼びへの応答の少なくともいずれかを含むデータを蓄積する。解析部１６は、当該データに基づく解析結果を出力する。
　また、解析部１６は、解析結果として、エレベーター３の乗客の待ち時間を含む情報を出力する。 Further, the buffer 15 stores data including at least one of the traveling state of the elevator 3, the open / closed state of the door of the elevator 3, the car load of the elevator 3, and the car position of the elevator 3 as state data. The analysis unit 16 outputs an analysis result based on the data.
In addition, the buffer 15 stores data including at least one of call registration, call allocation, and response to the call of the elevator 3 as state data. The analysis unit 16 outputs an analysis result based on the data.
Further, the analysis unit 16 outputs information including the waiting time of the passengers of the elevator 3 as the analysis result.
　これにより、解析部１６は、エレベーター３のサービスの状態を反映した解析結果を得ることができる。また、監視端末１２において、エレベーター３のサービスの状態を反映した解析結果によって遠隔監視が行われる。 As a result, the analysis unit 16 can obtain an analysis result that reflects the service status of the elevator 3. Further, in the monitoring terminal 12, remote monitoring is performed based on the analysis result reflecting the service status of the elevator 3.
　また、解析部１６は、予め設定された指定イベントの発生を解析結果が表す場合に、当該指定イベントが発生した時刻を含む予め設定された時間範囲に取得された状態データを当該解析結果と合わせて出力する。 Further, when the analysis result represents the occurrence of a preset designated event, the analysis unit 16 combines the state data acquired in the preset time range including the time when the designated event occurs with the analysis result. And output.
　これにより、エレベーター３の状態の履歴が解析結果と合わせて管理される。このため、発生した指定イベントの原因などの分析を監視端末１２において遠隔で行うことができる。 As a result, the history of the state of the elevator 3 is managed together with the analysis result. Therefore, the monitoring terminal 12 can remotely analyze the cause of the designated event that has occurred.
　また、解析部１６は、エレベーター３の乗客の待ち時間が予め設定された閾値を超えたことを指定イベントとする。
　また、解析部１６は、エレベーター３の満員通過を指定イベントとする。 Further, the analysis unit 16 sets that the waiting time of the passengers of the elevator 3 exceeds a preset threshold value as a designated event.
Further, the analysis unit 16 sets the full passage of the elevator 3 as a designated event.
　監視端末１２において、エレベーター３のサービスが低下した原因などの詳細な分析を遠隔で行うことができる。監視端末１２は、複数のエレベーター３についての情報を収集できる。このため、エレベーター３のサービスが低下した事象などについて統計的な分析を行うことができる。これにより、エレベーター３のサービスの向上を図ることができる。 On the monitoring terminal 12, detailed analysis such as the cause of the deterioration of the service of the elevator 3 can be performed remotely. The monitoring terminal 12 can collect information about a plurality of elevators 3. Therefore, it is possible to perform a statistical analysis on an event in which the service of the elevator 3 is lowered. As a result, the service of the elevator 3 can be improved.
　なお、エレベーター制御部は、例えばかご６を昇降させる巻上機の動作を制御する装置、かごドア８もしくは乗場ドアの開閉の動作を制御する装置、または呼びの登録もしくは割当てなどを管理する装置などの複数の装置を組み合わせたシステムであってもよい。このとき、複数の装置の各々は、局所的な通信路によって接続される。また、エッジサーバー４は、複数のサーバー装置などを組み合わせたシステムであってもよい。このとき、複数の装置の各々は、局所的な通信路によって接続される。 The elevator control unit is, for example, a device that controls the operation of a hoist that raises and lowers the car 6, a device that controls the opening and closing operation of the car door 8 or the landing door, a device that manages registration or assignment of calls, and the like. It may be a system in which a plurality of devices of the above are combined. At this time, each of the plurality of devices is connected by a local communication path. Further, the edge server 4 may be a system in which a plurality of server devices and the like are combined. At this time, each of the plurality of devices is connected by a local communication path.
　続いて、図３を用いて実施の形態１の変形例を説明する。
　図３は、実施の形態１の変形例に係る遠隔監視システムの構成図である。 Subsequently, a modified example of the first embodiment will be described with reference to FIG.
FIG. 3 is a configuration diagram of a remote monitoring system according to a modified example of the first embodiment.
　図３に示されるように、遠隔監視システム１は、記憶装置１８を備えてもよい。記憶装置１８は、例えば監視センターに設けられる。記憶装置１８は、第３通信路１９を通じて、複数のエレベーターシステム２の各々のエッジサーバー４に接続される。第３通信路１９は、広域的な通信路である。第３通信路１９は、例えばインターネット１４などの広域的なネットワークを経由する通信路である。第３通信路１９は、広域的なイントラネット、またはＶＰＮなどのネットワークを経由する通信路であってもよい。この例において、第３通信路１９は、エレベーターシステム２の外部を含む通信路である。 As shown in FIG. 3, the remote monitoring system 1 may include a storage device 18. The storage device 18 is provided in, for example, a monitoring center. The storage device 18 is connected to each edge server 4 of the plurality of elevator systems 2 through the third communication path 19. The third communication path 19 is a wide area communication path. The third communication path 19 is a communication path that goes through a wide area network such as the Internet 14. The third communication path 19 may be a communication path via a wide area intranet or a network such as VPN. In this example, the third communication path 19 is a communication path including the outside of the elevator system 2.
　複数のエレベーターシステム２の各々において、エッジサーバー４の解析部１６は、第３通信路１９を通じて記憶装置１８に状態データの解析結果を出力する。 In each of the plurality of elevator systems 2, the analysis unit 16 of the edge server 4 outputs the analysis result of the state data to the storage device 18 through the third communication path 19.
　記憶装置１８は、解析部１６から入力される解析結果を記憶する。指定イベントの発生を表す解析結果に合わせて状態データが出力される場合に、記憶装置１８は、当該状態データを当該解析結果と併せて記憶する。 The storage device 18 stores the analysis result input from the analysis unit 16. When the state data is output according to the analysis result indicating the occurrence of the designated event, the storage device 18 stores the state data together with the analysis result.
　記憶装置１８は、取得されるすべての状態データを記憶する必要がない。これにより、取得される状態データの量が増大しても、記憶装置１８の記憶容量の増大が抑制される。 The storage device 18 does not need to store all the acquired state data. As a result, even if the amount of acquired state data increases, the increase in the storage capacity of the storage device 18 is suppressed.
