In step ST1001, when it is not detected that the emergency stop switch 101 is pressed (in the case of “NO” in step ST1001), the emergency stop detection unit 110 repeats the process of step ST1001 and waits for an emergency stop instruction.

Description
また、例えば、特許文献2には、産業機器制御システムにおいて、タブレット端末が、無線通信信号発信器を介してサーバに蓄積されたデータにアクセスでき、複数のプログラマブルコントローラ各々に運転指令を送信することができるようにする技術が開示されている。
例えば、特許文献3には、収容ユニットとしてのクレードルを備え、クレードルに電子機器を収容することが開示されている。
また、例えば、特許文献4には、情報処理装置本体と、着脱可能なネットワークI/Fなどを持つ子機とで構成される情報処理装置技術が開示されている。
また、例えば、特許文献5には、携帯装置に着脱可能にクレードルを設ける技術が開示されている。
また、産業の現場においては、タブレット端末は、油の付いた手や、手袋をはめた状態では持ちづらく、専用のハードウェア操作系が必要となるという課題があった。
これに対し、特許文献3~5で開示されているような技術では、電子機器にクレードルを装着することが開示されており、特許文献5には、クレードルを持ちやすくすることについて開示されており、専用のハードウェア操作系としてクレードルを用いることが開示されている。しかしながら、タッチパネルにおける不用意な操作の誤動作の可能性について考慮されたものではないという課題があった。
実施の形態1.
図1は、この発明の実施の形態1に係るクレードル1に装着されたタブレット端末2(端末装置)によるシステム制御の概要を説明する図である。
この実施の形態1に係るクレードル1はタブレット端末2を装着し、図1に示すように、タブレット端末2とNCや設備、ロボットなどの自動化システム3の間に接続して使用される。
この実施の形態1では、クレードル1とタブレット端末2とは有線接続され、また、クレードル1と自動化システム3が備える各種機械とが有線接続される。このように、クレードル1と自動化システム3とが有線接続されることで、通信信頼性を確保することができる。
タブレット端末2は、市販のタブレット端末である。タブレット端末2は、スピーカ202aおよびマイク202b(スピーカ202aおよびマイク202bを、ここでは入出力部202とする)を備えるものであってもよい。
タブレット端末2は、自動化システム3を制御するための複数のアプリケーションを有している。
なお、タブレット端末2の下部には、USBコネクタ203が設けられており、このUSBコネクタ203に、クレードル1の接続ケーブル12の先端に設けられたUSBコネクタ121(詳細は後述する)を接続することで、タブレット端末2とクレードル1とが電気的、および、物理的に結合される。
クレードル1は、例えば、プラスチック成型によって形成されたハウジング100を有している。ハウジング100は、その前後方向(Z軸方向)を長手方向とした略直方体形状を有しており、全体として、大人の片手で把握可能な大きさである。一例として、ハウジング100は、人間の掌とほぼ同じ長さまたは幅を持つ大きさをしている。
また、下底支持部104cには、タブレット端末2の装着時に、タブレット端末2と接続するための接続ケーブル12を通すための穴105が設けられている(クレードル1とタブレット端末2とが接続された状態については図5を用いて後述する)。
グリップ102は、作業者がクレードル1を保持するグリップである。
イネーブルスイッチ103は、クレードル1にタブレット端末2が装着された場合に、タブレット端末2の操作を許可するためのスイッチである。作業者は、当該イネーブルスイッチ103を押すと、タブレット端末2の操作を行うことができる。
タブレット端末2は、背面が背面支持部104aによって支持され、上底が上底固定部104bによって固定され、下底が下底支持部104cによって支持されて、表示部201が見えるように端末保持部104に保持されている。
また、クレードル1のハウジング100に電源ボタン(図示しない)を設け、作業者により電源ボタンがオンされると、図示しないACアダプタを経て電源が供給され、通電状態となるようにしてもよい。
なお、図7では、クレードル1の左側面にスペース14の蓋を設け、蓋を下側から開閉するようにしているが(図7(b)参照)、これに限らず、クレードル1に接続ケーブル12を収納するスペース14が設けられていればよい。
図8は、実施の形態1において、タブレット端末2とクレードル1とがUSBコネクタ203,121を介して接続され、クレードル1と自動化システム3とがコネクタ131,303を介して接続されたときの電気的構成の一例を示す図である。
タブレット端末2は、USBコネクタ203と、表示部201と、入出力部202と、操作部204と、受電部205と、制御部206と、操作アプリケーション207とを備える。
入出力部202は、タブレット端末2が有するアプリケーションの実行に応じて再生音楽や通話音声などの音を出力する。また、作業者は、入出力部202から音声にて操作の指示を行うこともできる。なお、ここでは、タブレット端末2が入出力部202を備えるものとしているが、入出力部202は備えないものとしてもよい。
操作部204は、作業者が表示部201、または、入出力部202から入力した操作を受け付ける。操作部204が受け付けた操作情報は、制御部206に送られ、制御部206から、USBコネクタ203を介してクレードル1に送られる。
受電部205は、USBコネクタ203を介してクレードル1から電源供給を受ける。
制御部206は、タブレット端末2を制御する。例えば、制御部206は、操作部204が受け付けた操作情報を、USBコネクタ203を介してクレードル1に送信したり、タブレット端末2が備える操作アプリケーション207の動作を制御したりする。
操作アプリケーション207は、タブレット端末2を動作させるためのアプリケーションである。
クレードル1は、コネクタ131,303を介して、タブレット端末2で制御する自動化システム3の機械と電気的に接続される。
イネーブルスイッチ103は、クレードル1にタブレット端末2が装着された場合に、タブレット端末2の操作を許可するためのスイッチである。
また、装着検知部106は、タブレット端末2が端末保持部104から取り外されたことを検知することもできる。例えば、端末保持部104にセンサを備えるようにし、当該センサがタブレット端末2を検出しなくなったことを検知し、タブレット端末2が端末保持部104から取り外されたと判断する。
また、動作制御部108は、緊急停止検知部110から緊急停止通知を受信すると、USBコネクタ121,203を介して、タブレット端末2の制御部206に対して、表示部201に、自動化システムの機械が緊急停止中である旨のメッセージを表示させるようにすることもできる。また、動作制御部108は、制御部206に対して、入出力部202に、緊急停止中である旨の音声を出力させるようにしてもよい。
操作指示部109は、動作制御部108がタブレット端末2の操作部204から、制御部206、USBコネクタ203,121を介して受け付けた操作情報を受信し、コネクタ131と自動化システム3のコネクタ303とを介して、自動化システム3が有する機械の制御部301に操作情報を通知する。自動化システム3の機械の制御部301では、通知された操作情報に従って、各種アプリケーション302の制御を行う。
なお、タブレット端末2には、予め操作アプリケーション207がインストールされている。そして、操作アプリケーション207は、自動化システム3の各種アプリケーション302から操作情報を通信して、タブレット端末2で自動化システム3の操作を可能とする。操作情報としては、自動化システム3のON/OFF、各パラメータの調整、動作モードの切り替えなどである。
受電部111は、自動化システム3が有する機械のコネクタ303とコネクタ131とを介して、自動化システムからの受電を開始する(ステップST901)。受電部111への給電が開始され、クレードル1に電源が入ると、初期化が行われ、自動化システム3の機械からクレードル1へ電源が供給される。なお、初期化とは、クレードル1電源投入時の初期設定処理であり、クレードル1を使用できる状態にする処理のことである。
受電部111は、自動化システム3との接続フラグがONになったかどうかを判定する(ステップST902)。クレードル1と、作業者が制御しようとする自動化システム3が有する機械とは、接続ケーブル13で接続されることにより電気的に結合される。自動化システム3の機械が有するコネクタ303と、クレードル1のコネクタ131とが接続され、クレードル1に電源が供給されると、クレードル1が内部的に保有する自動化システム3との接続フラグがONとなる。そこで、このステップST902では、受電部11が、当該自動化システム3との接続フラグがONになったかどうかを判定することで、自動化システム3とクレードル1とが電気的に結合され、電源が供給されたかどうかを判断する。
なお、この時、タブレット端末2が入出力部202を有する場合には、動作制御部108は、制御部206に対して、入出力部202に、音声入力等を禁止させる操作抑制指示信号を送信するようにする。
具体的には、例えば、クレードル1の内部に操作抑制フラグを保持し、動作制御部108において操作抑制指示信号を送信した際(ステップST906)に当該操作抑制フラグをONにするようにし、解除検知部107は、作業者によりイネーブルスイッチが押されたことを検知した場合(ステップST907)に、当該操作抑制フラグをOFFすることにより、動作制御部108に、操作受付禁止の解除指示を受け付けたことを通知する(ステップST908)。
タブレット端末2の制御部206では、この操作抑制解除信号を受信し、表示部201に対して、作業者からの操作受付を許可する画面の制御を行う。
これにより、作業者は、タブレット端末2の操作が可能となり、タブレット端末2の表示部から、自動化システム3を制御する操作を行うことができるようになる。
また、この時、動作制御部108は、制御部206に対して、表示部21に、操作禁止が解除された旨のメッセージを表示する制御を行わせるようにしてもよいし、入出力部202に、操作禁止が解除された旨の音声を出力する制御を行わせるようにしてもよい。
ステップST909により、作業者によるタブレット端末2の操作が可能になると、作業者は、タブレット端末2より、自動化システム3を制御する操作を行う。
そこで、タブレット端末2の表示部201、あるいは、入出力部202から、作業者による自動化システム3を制御する操作が入力されると、タブレット端末2の操作部204は、当該操作を受け付ける。そして、操作部204は、受け付けた操作内容の操作情報を、制御部206を介して、クレードル1の動作制御部108へ通知する。
動作制御部108は、ステップST910において、当該操作情報を受け付けたかどうか、すなわち、作業者がタブレット端末2を操作することによって、自動化システム3の制御を行ったかどうかを判断する。
自動化システム3が有する機械では、制御部301が、各種アプリケーション302に対して、操作情報に従った制御を行う。これにより、作業者がタブレット端末2から入力した操作に応じた自動化システム3の制御が可能となる。
ステップST912において、タブレット端末2との接続フラグ、または、自動化システム3との接続フラグがOFFになった場合(ステップST912の“YES”の場合)、すなわち、クレードル1とタブレット端末2、または、クレードル1と自動化システム3との接続が解除された場合、動作停止処理を行う(ステップST913)。具体的には、受電部111は、クレードル1の給電を停止する。また、クレードル1とタブレット端末2との接続はされた状態で、クレードル1と自動化システム3との接続が解除された場合は、動作制御部108は、給電停止を受け、USBコネクタ121,203を介して、タブレット端末2の表示部201に対して、自動化システム3との接続が解除された旨の表示を行う制御を行わせるようにしてもよい。また、タブレット端末2が入出力部202を有する場合には、動作制御部108は、入出力部202に対して、自動化システム3との接続が解除された旨の音声出力を行う制御を行わせるようにしてもよい。
図10は、この実施の形態1において、作業者による、自動化システム3の緊急停止指示があった場合のクレードル1の動作を説明するフローチャートである。
ステップST1001において、緊急停止スイッチ101が押されたことが検知されない場合(ステップST1001の“NO”の場合)、緊急停止検知部110は、ステップST1001の処理を繰り返し、緊急停止指示を待機する。
なお、操作抑制指示信号を送信する際、動作制御部108は、クレードル1が内部的に保持している操作抑制フラグをONにする。
このように、クレードル1に緊急停止スイッチ101を設け、緊急停止の操作は、イネーブルスイッチ103が押されていることを必要としないようにしたので、咄嗟の事態にも自動化システムの機械を迅速に停止させることができる。
また、クレードル1のグリップ形状を手にフィットする形状としたので、持ちやすさを向上させることができる。
また、緊急停止の操作は、イネーブルスイッチ103が押されていることを必要としないようにしたので、咄嗟の事態にも自動化システム3の機械を迅速に停止させることができる。
実施の形態1では、クレードル1と、自動化システム3とは、有線で接続されていた。
この実施の形態2では、クレードル1と自動化システム3とを、無線で接続する実施の形態について説明する。
実施の形態1において、図1を用いて説明したものとは、クレードル1と自動化システム3との接続が信頼性の高い無線通信方式での無線接続になった点が異なるのみである。
なお、クレードル1と自動化システム3とを信頼性の高い無線通信方式での無線接続とすることで、市販のタブレット端末と自動化システム3との無線接続よりも信頼性の高い通信環境を提供できる。
その他の点については、図1を用いて説明したものと同様であるので、重複した説明を省略する。
この実施の形態2に係るクレードル1の外観については、実施の形態1において図3を用いて説明したものに、接続ケーブル13を有さないようにした点が異なるのみであるので図示および重複した説明を省略する。
タブレット端末2とクレードル1との電気的構成については、実施の形態1において図8を用いて説明したものと同様であるので重複した説明を省略する。
実施の形態1と実施の形態2では、図12に示すように、クレードル1に取替可能に収容される充電式のバッテリ113を備え、受電部111は、バッテリ113から電源供給を受ける点が異なる。
クレードル1の通信部112は、自動化システム3の通信部304との間で無線通信を確立して、無線通信を行う。
このように、信頼性の高い無線通信方式を採用することで、通信信頼性を向上できる。
また、この実施の形態2では、上述したように、クレードル1にバッテリ113を備え、タブレット端末2も、当該バッテリ113から電源供給を受けるため、タブレット端末2の長時間使用が可能となり、予期せぬシャットダウンなどの可能性が低減する。この観点からも、通信信頼性を向上できる。
また、クレードル1のグリップ形状を手にフィットする形状としたので、持ちやすさを向上させることができる。
また、緊急停止の操作は、イネーブルスイッチ103が押されていることを必要としないようにしたので、咄嗟の事態にも自動化システムの機械を迅速に停止させることができる。
また、実施の形態1,2におけるクレードル1の制御に用いられる各部は、ソフトウェアに基づくCPUを用いたプログラム処理によって実行される。
