Description
本開示の一態様である映像判別システムは、数値制御装置又は工作機械の両方、又は少なくとも一方である機械の状態に係るデータの識別情報と、該データの内容とを紐づける機械状態辞書部と、前記機械の映像を取得する映像取得部と、前記機械の状態変化の検出に用いるデータを取得する機械状態取得部と、前記データを基に、前記機械の状態の変化を検出し、前記機械状態辞書部を参照して、前記データの変化を前記機械の操作内容に変換し、前記機械の状態が変化したときの映像と、前記データの内容と、を紐づけるデータ紐づけ部と、を備える。
本開示の一態様である記憶媒体は、1つ又は複数のプロセッサが実行することにより、数値制御装置又は工作機械の両方、又は少なくとも一方である機械の状態に係るデータの識別情報と、該データの内容とを紐づける機械状態辞書部を記憶し、前記機械の映像を取得し、前記機械の状態変化の検出に用いるデータを取得し、前記データを基に、前記機械の状態が変化したか否かを判断し、前記機械の状態が変化したときの映像と、前記データの内容と、を紐づける、コンピュータが読み取り可能な命令を記憶する。
記憶媒体。
図1は、第1の開示の映像判別装置としての数値制御装置100のブロック図である。
数値制御装置100は、映像取得部1、機械状態取得部2、機械状態辞書部3、機械状態変換部4、データ紐づけ部5を備える。
操作盤やタッチパネルなどの操作信号は、「機械の状態変化の検出に用いるデータ」となりうる。機械状態変換部4は、操作信号を監視し、操作信号が変化した場合には、機械状態辞書部3を参照し、変化した操作信号の「データの内容」を読み出す。データ紐づけ部は、「データの値」及び「データの内容」の両方、又は少なくとも一方と、映像と紐づける。
例えば、オペレータが操作盤の速度ダイヤルを手動操作し、速度信号が「10から20」に変化すると、データ紐づけ部5は、「工作機械軸の移動速度が変化する」映像と、データの内容「速度」と、データの値「10->20」と、を紐づける。
例えば、タッチパネルの「加工開始ボタン」の押下により、加工開始信号がOFFからONに変化すると、データ紐づけ部5は、「ワークの加工が開始する」映像と、データの内容「加工開始」と、を紐づける。
例えば、変数として、「実行する加工プログラムの番号」が変更された場合、データ紐づけ部は、「加工プログラムの番号が変更される」映像と、データの内容「実行する加工プログラムの番号」と、データの値「加工プログラムの番号」と、を紐づける。
ここで、映像に紐づけるデータの内容は、「変数の変更を実行したアプリケーションの名称」「変数の変更を実行した外部の情報機器の名称」なども用いることができる。「加工プログラムの番号が変更される」映像は、数値制御装置100の表示部70のキャプチャ映像でもよい。
センサからの入力信号は、「機械の状態変化の検出に用いるデータ」となりうる。例えば、温度センサが検出する「主軸温度」は、「機械の状態変化の検出に用いるデータ」である。「主軸温度」が所定の値を超えると、データ紐づけ部5は、データの内容「主軸温度」と、データの値「主軸温度の値」と、「主軸」の映像と、を紐づける。温度が上昇すると、「主軸」は、発煙することもある。
例えば、「工作機械のドア開閉信号」は、「機械の状態変化の検出に用いるデータ」となりうる。「ドアの開閉信号」が変化すると、PLC(数値制御装置100に内蔵のPLC、又は、数値制御装置100の外部のPLC)は、信号の値に従いドアの開閉を行う。データ紐づけ部5は、外部機器の映像と、データの変化とを紐づける。例えば、「ドアの開閉信号」がONになると、データ紐づけ部5は、「ドアが開く」映像と、データの内容「ドアの開閉信号」と、データの値「OFF->ON」と、を紐づける。
「クーラント信号」は、「機械の状態変化の検出に用いるデータ」となりうる。「クーラント信号」が変化すると、PLC(数値制御装置100に内蔵のPLC、又は、数値制御装置100の外部のPLC)は、信号の値に従いクーラントの噴出を行う。データ紐づけ部5は、外部機器の映像と、データの変化を紐づける。例えば、「クーラント信号」がONになると、データ紐づけ部5は、「クーラントの噴出が開始する」映像と、データの内容「クーラント信号」と、データの値「OFF->ON」と、を紐づける。
数値制御装置100では、図2に示すように、ローカル変数、マクロ変数、コモン変数、システム変数などの変数が数値制御装置100のメモリ上に設定されている。また、パラメータ番号も決まっている。変数の番号やパラメータの番号をデータの識別情報として用いることができる。
ローカル変数は、メインプログラムやマクロプログラムなどの加工プログラムの実行時に用いる変数であり、メインプログラムとマクロプログラムでそれぞれ独立している。コモン変数は、メインプログラムとマクロプログラムで共通に使用する変数である。
システム変数は、工具径補正の変更や、座標値の読込み、有効な指令(Gコード)、有効なMコード(シーケンス指令)などを記憶する。システム変数には、インタフェース入力信号、インタフェース出力信号、セッティングデータ、モーダル情報などがある。
これらの変数の値から機械状態の変化を検出することができる。
本開示では、機械状態の内で、特にオペレータによる数値制御装置の操作に着目して映像との紐づけを行う実施形態について説明する。
図3は、本開示の映像判別装置としての数値制御装置100と、数値制御装置100に信号を送信する装置とを示す概念図である。図3において数値制御装置100は、マシニングセンタに含まれる。マシニングセンタは、数値制御装置100と工作機械が一体になった装置である。マシニングセンタは、サーボモータ、ファン、集霧機、クーラント、切粉除去装置、自動工具交換装置(ATC)、積層表示灯(パトライト(登録商標))などの装置も含む。数値制御装置100は、内部PLC(Programmable Logic Controller)42を備え、これらの機器を制御する。
オペレータの操作を時系列に並べることで手順書が自動的に作成できる。操作手順書には、時間情報を含めてもよい。映像に字幕を付けてもよい。
映像選択部20では、代表映像を選択することもできる。代表映像は、要約映像や手順書の表紙映像として用いられる。図13の例では、[1]乃至[6]のキーフレームの一覧から、[4]のキーフレームが代表映像として選択されると、キーフレーム[4]を表紙とする要約映像が作成される様子を示している。
第2の開示では、映像の録画とデータの紐づけとを同時に行ったが、第3の開示では、加工中に録画した映像と加工中の操作信号を用いてデータの紐づけを行う。第3の開示の映像判別装置200は、図15に示すように、録画した映像を記憶する映像記憶部21と、加工中の操作信号を記憶するデータ記憶部22とを備える。映像取得部11は映像記憶部21に記憶する映像を読み出し、操作信号取得部12はデータ記憶部22に記憶する操作信号を読み出す。
例えば、第2の開示で示した字幕作成部16、要約映像作成部18、手順書作成部19、映像選択部20、第3の開示で示した映像記憶部21、データ記憶部22などの機能は、第1の開示に係る映像判別装置と適宜組み合わせて利用することができる。この場合、それぞれの機能は操作内容だけでなく機械の様々な状態を示すデータに基づいて字幕、要約、手順書、代表映像の作成、データの記憶をする。
図16を参照して、第1の開示の数値制御装置100のハードウェア構成を説明する。なお、第2,第3の開示の映像判別装置200も略同じハードウェア構成を有する。数値制御装置100が備えるCPU111は、数値制御装置100を全体的に制御するプロセッサである。CPU111は、バスを介してROM112に加工されたシステム・プログラムを読み出し、該システム・プログラムに従って数値制御装置100の全体を制御する。RAM113には、一時的な計算データや表示データ、入力部71を介してユーザが入力した各種データ等が一時的に格納される。
