　（３．１）インバータの機能ブロック構成 (3.1) Functional block configuration of inverter
　インバータ２００は、モータ制御回路２１０に加えて、正常波形登録部２４２と、正常波形記憶部２５１と、判定開始部２４３と、異常判定部２４４と、異常波形記憶部２５２と、異常波形送信部２４５と、登録開始部２４６と、通信部２３０とを有する。 In addition to motor control circuit 210, inverter 200 includes normal waveform registration unit 242, normal waveform storage unit 251, determination start unit 243, abnormality determination unit 244, abnormal waveform storage unit 252, and abnormal waveform transmission unit 245. , A registration start unit 246, and a communication unit 230.
　正常波形登録部２４２は、ユーザ操作に基づいて、エレベータ２が動作した際のモータ制御回路２１０内の動作波形を正常波形情報として、当該動作における所定動作条件を表す条件情報に紐付けて正常波形記憶部２５１に記憶させる。例えば、エレベータ２のインストール時やメンテナンス時に、ユーザ（作業者）が操作ユニット２２０に対して登録操作を行う。或いは、ユーザがモバイル端末４００を用いて遠隔で登録操作を行ってもよい。正常波形登録部２４２は、かかる登録操作に応じて、正常波形情報及び条件情報のセットを正常波形記憶部２５１に記憶させる。 The normal waveform registration unit 242 associates the operation waveform in the motor control circuit 210 when the elevator 2 operates with normal waveform information based on the user operation, and links it to the condition information representing the predetermined operation condition in the operation and outputs the normal waveform. It is stored in the storage unit 251. For example, at the time of installation or maintenance of the elevator 2, a user (worker) performs a registration operation on the operation unit 220. Alternatively, the user may perform registration operation remotely using the mobile terminal 400. The normal waveform registration unit 242 stores the set of normal waveform information and condition information in the normal waveform storage unit 251 according to the registration operation.
　ここで、モータ制御回路２１０内の動作波形とは、モータ制御回路２１０のコンバータ部の出力電流・電圧、モータ制御回路２１０の平滑回路部の出力電流・電圧、モータ制御回路２１０のインバータ部の出力電流・電圧（モータ１００への相電流・相電圧）、モータ制御回路２１０の駆動部の出力電流・電圧のうち少なくとも１つの波形である。波形情報は、かかる波形をそのままサンプリングしたデータにより構成されてもよいし、かかる波形を信号処理によって変換して得られた波形をサンプリングしたデータにより構成されてもよい。また、プロセッサ２４０をモータ制御回路２１０の一部とみなしてもよい。この場合、モータ制御回路２１０内の動作波形とは、例えば、プロセッサ２４０内やモータ制御回路２１０内で生成又は使用される各種の指令信号、応答信号、制御信号等の波形であってもよい。このような動作波形としては、例えば、モータ回転速度を指定する速度指令やそれに対する速度応答、モータ回転位置を指定する位置指令や位置フィードバック信号、モータ回転トルクを指定するトルク指令やモータが発生したトルク値、モータ供給電流を指定する電流指令やモータに供給された電流、モータ供給電圧を指定する電圧指令やモータに供給された電圧、等が挙げられる。波形情報は、かかる指令信号の波形をそのままサンプリングしたデータにより構成されてもよいし、かかる波形を信号処理によって変換して得られた波形をサンプリングしたデータにより構成されてもよい。 Here, the operation waveform in the motor control circuit 210 refers to the output current / voltage of the converter unit of the motor control circuit 210, the output current / voltage of the smoothing circuit unit of the motor control circuit 210, the output of the inverter unit of the motor control circuit 210. At least one of the current and voltage (phase current and phase voltage to the motor 100) and the output current and voltage of the drive unit of the motor control circuit 210 is used. The waveform information may be constituted by data obtained by sampling such a waveform as it is, or may be constituted by data obtained by sampling a waveform obtained by converting the waveform by signal processing. Also, processor 240 may be considered part of motor control circuit 210. In this case, the operation waveform in the motor control circuit 210 may be, for example, waveforms of various command signals, response signals, control signals, etc. generated or used in the processor 240 or in the motor control circuit 210. As such an operation waveform, for example, a speed command specifying a motor rotational speed, a speed response to it, a position command or position feedback signal specifying a motor rotational position, a torque command specifying a motor rotational torque, or a motor generated The torque value, a current command specifying a motor supply current, a current supplied to the motor, a voltage command specifying a motor supply voltage, a voltage supplied to the motor, and the like can be mentioned. The waveform information may be constituted by data obtained by sampling the waveform of the command signal as it is, or may be constituted by data obtained by sampling a waveform obtained by converting the waveform by signal processing.
　条件情報としては、モータ２００を含むエレベータ２に関連する各種の条件が使用可能である。この条件情報としては、例えば、モータ回転速度、モータ回転時間、モータ回転位置の変化量、モータ発生トルク値、ブレーキの状態（ブレーキが動作しているか否か）、乗りかご１４の荷重（すなわち、ロードセンサの検出値）、乗りかご１４の出発階及び／又は到着階、スケジューリングされたエレベータ２の自動運転、エレベータ２の動作時間帯等が挙げられる。条件情報は、これらの条件のうち１つであってもよいし、２以上の条件の組み合わせであってもよい。但し、条件情報は、これに限られるものではなく、モータ制御回路２１０内の動作波形に影響を与えるものであれば、どのようなものであってもよい。条件情報は、エレベータ２が動作した際の時間帯や季節、天候等を更に含んでもよい。正常波形登録部２４２は、条件情報をユーザ入力によって取得してもよいし、条件情報を上位コントローラ３００から取得してもよい。 As the condition information, various conditions related to the elevator 2 including the motor 200 can be used. As this condition information, for example, motor rotation speed, motor rotation time, change amount of motor rotation position, motor generated torque value, state of brake (whether brake is operating or not), load of car 14 (ie, The detected value of the load sensor, the departure floor and / or the arrival floor of the car 14, the automatic operation of the elevator 2 scheduled, the operating time zone of the elevator 2, etc. may be mentioned. The condition information may be one of these conditions or a combination of two or more conditions. However, the condition information is not limited to this, and may be anything as long as it affects the operation waveform in the motor control circuit 210. The condition information may further include a time zone, a season, weather, and the like when the elevator 2 operates. The normal waveform registration unit 242 may acquire condition information by user input, or may acquire condition information from the host controller 300.
　正常波形記憶部２５１は、エレベータ２が所定動作条件で動作した際のモータ制御回路２１０内の動作波形を表す正常波形情報を記憶する。実施形態において、正常波形記憶部２５１は、正常波形登録部２４２によって登録された正常波形情報及び条件情報を記憶する。その結果、正常波形記憶部２５１には、所定動作条件を表す条件情報が、対応する正常波形情報と紐付けられて記憶される。正常波形記憶部２５１は、条件情報と正常波形情報とのセットを複数記憶してもよい。 The normal waveform storage unit 251 stores normal waveform information representing an operation waveform in the motor control circuit 210 when the elevator 2 operates under a predetermined operation condition. In the embodiment, the normal waveform storage unit 251 stores the normal waveform information and the condition information registered by the normal waveform registration unit 242. As a result, the normal waveform storage unit 251 stores condition information representing the predetermined operation condition in association with the corresponding normal waveform information. The normal waveform storage unit 251 may store a plurality of sets of condition information and normal waveform information.
　判定開始部２４３は、所定条件情報に基づいて、異常判定部２４４に判定を開始させる。例えば、判定開始部２４３は、稼働中のエレベータ２の現在の動作条件（例えば、モータ回転速度、モータ回転時間、及び乗りかご１４の荷重等）を監視し、正常波形記憶部２５１に記憶された条件情報と現在の動作条件とが合致するか否かを判定し、合致する場合に異常判定部２４４に判定を開始させると判定する。判定開始部２４３は、条件情報として、例えば、上位コントローラ３００からの特定の指令、動作時間、動作内容等の様々な条件をトリガとして、自動で判定を開始することができる。 The determination start unit 243 causes the abnormality determination unit 244 to start the determination based on the predetermined condition information. For example, the determination start unit 243 monitors the current operating conditions (for example, motor rotation speed, motor rotation time, load of the car 14, etc.) of the elevator 2 in operation, and is stored in the normal waveform storage unit 251. It is determined whether the condition information and the current operation condition match, and when the conditions match, it is determined to cause the abnormality determination unit 244 to start the determination. The determination start unit 243 can automatically start determination using, as a condition information, various conditions such as a specific command from the upper controller 300, an operation time, and an operation content as a trigger.
　正常波形記憶部２５１が条件情報と正常波形情報とのセットを複数記憶する場合、判定開始部２４３は、正常波形記憶部２５１に記憶された複数の条件情報に基づいて、比較に使用する１の正常波形情報を抽出してもよい。例えば、判定開始部２４３は、稼働中のエレベータ２の現在の動作条件を監視し、正常波形記憶部２５１に記憶された複数の条件情報のいずれかと現在の動作条件とが合致するか否かを判定し、合致すると判定した条件情報に紐付けられた正常波形情報を正常波形記憶部２５１から抽出し、抽出した正常波形情報を異常判定部２４４に出力する。 When the normal waveform storage unit 251 stores a plurality of sets of condition information and normal waveform information, the determination start unit 243 is used for comparison based on the plurality of condition information stored in the normal waveform storage unit 251. Normal waveform information may be extracted. For example, the determination start unit 243 monitors the current operation condition of the elevator 2 in operation, and determines whether any one of the plurality of condition information stored in the normal waveform storage unit 251 matches the current operation condition. The normal waveform information that is determined and linked to the condition information that is determined to match is extracted from the normal waveform storage unit 251, and the extracted normal waveform information is output to the abnormality determination unit 244.
　異常判定部２４４は、正常波形記憶部２５１に記憶された正常波形情報に基づいて、稼働中のエレベータ２が所定動作条件で動作した際のモータ制御回路２１０内の動作波形を表す稼働中波形情報を、正常波形情報と比較することによって、モータ制御回路２１０が正常に稼動しているか否かを判定する。例えば、判定開始部２４３は、判定開始部２４３から正常波形情報が出力された際に、モータ制御回路２１０内の動作波形を表す稼働中波形情報を取得し、取得した稼働中波形情報を、判定開始部２４３から出力された正常波形情報と比較する。 Based on the normal waveform information stored in the normal waveform storage unit 251, the abnormality determination unit 244 is an operating waveform information indicating an operation waveform in the motor control circuit 210 when the elevator 2 in operation operates under a predetermined operation condition. Is compared with the normal waveform information to determine whether the motor control circuit 210 is operating normally. For example, when the normal waveform information is output from the determination start unit 243, the determination start unit 243 acquires the in-operation waveform information representing the operation waveform in the motor control circuit 210, and determines the acquired in-operation waveform information The normal waveform information output from the start unit 243 is compared.
　そして、異常判定部２４４は、稼働中波形情報が正常波形情報と一致しない場合に、モータ制御回路２１０が正常に稼動していないと判定する。或いは、異常判定部２４４は、稼働中波形情報と正常波形情報との差（乖離）が閾値よりも大きい場合に、モータ制御回路２１０が正常に稼動していないと判定してもよい。例えば、稼働中波形情報と正常波形情報との差分値をサンプル値ごとに算出して積算し、積算値を閾値と比較し、積算値が閾値を超える場合に、モータ制御回路２１０が正常に稼動していないと判定してもよい。異常判定部２４４は、モータ制御回路２１０が正常に稼働していないと判定した場合に、その際の稼働中波形情報を異常波形情報として異常波形記憶部２５２に出力する。 Then, when the operating waveform information does not match the normal waveform information, the abnormality determining unit 244 determines that the motor control circuit 210 is not operating normally. Alternatively, the abnormality determination unit 244 may determine that the motor control circuit 210 is not operating normally when the difference (deviation) between the operating waveform information and the normal waveform information is larger than a threshold. For example, the difference value between in-operation waveform information and normal waveform information is calculated and integrated for each sample value, and the integrated value is compared with the threshold, and the motor control circuit 210 operates normally when the integrated value exceeds the threshold. It may be determined that it is not. If the abnormality determination unit 244 determines that the motor control circuit 210 is not operating normally, the abnormality determination unit 244 outputs the in-operation waveform information at that time to the abnormal waveform storage unit 252 as abnormal waveform information.
　異常波形記憶部２５２は、異常判定部２４４によりモータ制御回路２１０が正常に稼働していないと判定された際の稼働中波形情報を異常波形情報として記憶する。 The abnormal waveform storage unit 252 stores, as abnormal waveform information, in-operation waveform information when the abnormality determination unit 244 determines that the motor control circuit 210 is not operating normally.
　通信部２３０は、モバイル端末４００と通信する機能を有する。実施形態において、通信部２３０は、モバイル端末４００との無線接続を確立することによって、モバイル端末４００との無線通信を行う。或いは、通信部２３０は、インバータ２００の通信部２３０がモバイル端末４００との有線接続を確立することによって有線通信を行ってもよい。有線接続は、ＵＳＢ接続であってもよい。 The communication unit 230 has a function of communicating with the mobile terminal 400. In the embodiment, the communication unit 230 performs wireless communication with the mobile terminal 400 by establishing wireless connection with the mobile terminal 400. Alternatively, the communication unit 230 may perform wired communication by establishing a wired connection with the mobile terminal 400 by the communication unit 230 of the inverter 200. The wired connection may be a USB connection.
　異常波形送信部２４５は、通信部２３０とモバイル端末４００との通信が確立された際に、異常波形記憶部２５２に記憶された異常波形情報をモバイル端末４００に送信する。 When communication between the communication unit 230 and the mobile terminal 400 is established, the abnormal waveform transmission unit 245 transmits the abnormal waveform information stored in the abnormal waveform storage unit 252 to the mobile terminal 400.
　その後、ユーザ操作に基づいて、インバータ２００（モータ制御回路２１０）のパラメータが変更され得る。パラメータは、インバータ２００の動作を制御するためにユーザが設定する各種の値である。パラメータとしては、例えば、環境設定のパラメータ、運転モード設定のパラメータ、モータ加減速時間のパラメータ、モータトルク補償のパラメータ、速度制御（ＡＳＲ）の設定パラメータ、周波数指令の設定パラメータ、Ｖ／ｆ特性の設定パラメータ等が挙げられるが、これらの例に限定されるものではなく、インバータ２００の動作を制御する際に使用されるパラメータであれば様々なパラメータが使用可能である。かかる設定パラメータは、ユーザが操作ユニット２２０に対して操作を行うこと、又はユーザがモバイル端末４００を用いて遠隔で操作を行うことによって変更される。 Thereafter, parameters of the inverter 200 (motor control circuit 210) may be changed based on a user operation. The parameters are various values set by the user to control the operation of the inverter 200. The parameters include, for example, environment setting parameters, operation mode setting parameters, motor acceleration / deceleration time parameters, motor torque compensation parameters, speed control (ASR) setting parameters, frequency command setting parameters, and V / f characteristics. Although setting parameters and the like can be mentioned, the present invention is not limited to these examples, and various parameters can be used as long as the parameters are used when controlling the operation of the inverter 200. Such setting parameters are changed by the user operating the operation unit 220 or by the user remotely operating the mobile terminal 400.
　登録開始部２４６は、モータ制御回路２１０のパラメータが変更された場合、正常波形登録部２４２に、少なくとも正常波形情報の正常波形記憶部２５１への記憶を開始させる。パラメータ変更があった場合には動作波形も変わるので、登録開始部２４６は、モータ制御回路２１０のパラメータ変更に応じて、正常波形記憶部２５１の内容を最新の状態へ更新する。例えば、登録開始部２４６は、パラメータが変更された後、条件情報に一致した動作を検知した際にモータ制御回路２１０から波形情報を取得し、取得した波形情報によって自動で正常波形記憶部２５１の内容を更新してもよい。或いは、登録開始部２４６は、正常波形記憶部２５１に記憶された条件情報に一致した動作をモータ制御回路２１０（インバータ２００）に開始させることによってモータ制御回路２１０から波形情報を取得し、取得した波形情報によって自動で正常波形記憶部２５１の内容を更新してもよい。或いは、登録開始部２４６は、新たに所定の動作をモータ制御回路２１０（インバータ２００）に実行させて、波形とともに、正常波形記憶部２５１に記憶された条件情報も更新させてもよい。 When the parameter of the motor control circuit 210 is changed, the registration start unit 246 causes the normal waveform registration unit 242 to start storing at least normal waveform information in the normal waveform storage unit 251. When the parameter is changed, the operation waveform is also changed, so that the registration start unit 246 updates the contents of the normal waveform storage unit 251 to the latest state according to the parameter change of the motor control circuit 210.
