In such a remote operation system, when an error occurs in the work device, information about the error (error information) is sent to the remote monitoring unit. Then, when the operator of the remote monitoring unit performs an error elimination operation (error elimination operation) based on the error information, the operation information is transmitted to the work device, and the work device operates according to the operation information, thereby eliminating the error. The problem is solved (for example, Patent Document 1 below).
このようなリモート操作システムにおいて、リモート監視部が複数設置されている場合には、作業装置とリモート監視部の間に中継部としてのサーバを配置し、エラー情報をどのリモート監視部に送信するか、すなわちエラー解消操作のジョブをどのリモート監視部に与えるかをサーバが選択できる構成とすることができる。この場合、サーバは各リモート監視部のステータス(状態)を把握し、オペレータがエラー解消操作を行うことができる状態にあるリモート監視部にエラー情報を送信することになる。
In such a remote operation system, when a plurality of remote monitoring units are installed, a server as a relay unit is arranged between the working device and the remote monitoring unit, and which remote monitoring unit to send the error information to. In other words, the configuration can be such that the server can select to which remote monitoring unit the error resolution operation job is given. In this case, the server grasps the status (state) of each remote monitoring unit, and transmits error information to the remote monitoring unit that is in a state where the operator can perform an error elimination operation.
しかしながら、サーバが全てのリモート監視部のステータスを把握していても、各オペレータは他のリモート監視部の状態(すなわち他のオペレータの状態)がどのようになっているかが分からないので、エラー解消処理をスムーズに進行させるにおいて必ずしも適切な行動をとれず、リモート操作システムの全体におけるエラー解消処理が停滞してしまう事態が起こり得る。
However, even if the server knows the status of all remote monitors, each operator does not know the status of other remote monitors (that is, the status of other operators). Appropriate actions may not always be taken to smoothly proceed with processing, and a situation may occur in which error resolution processing in the entire remote operation system stagnate.
そこで本開示は、各オペレータが他のリモート監視部のステータスに応じた適切な行動をとることができ、エラー解消処理が停滞してしまう事態を防止することができるリモート操作システムを提供することを目的とする。
Therefore, the present disclosure aims to provide a remote operation system that allows each operator to take appropriate action according to the status of other remote monitoring units and prevents the situation where error resolution processing is stagnant. aim.

In FIGS. 3 and 4, the substrate camera 16 is attached to the mounting head 15 with the imaging optical axis facing downward. The substrate camera 16 is moved in the horizontal plane direction together with the mounting head 15 by the head moving mechanism 14 .
図5は、本開示の一実施の形態におけるリモート操作システム1の制御系統を示すブロック図である。各作業装置2の各部の動作は、その制御部である作業装置制御部17(図3)によって制御される。具体的には、作業装置制御部17は、図5に示すように、搬送コンベア12、テープフィーダ13、ヘッド移動機構14および装着ヘッド15の各動作を制御する。これにより搬送コンベア12は基板KBの搬送および位置決めを行い、各テープフィーダ13は部品供給位置13Kに部品BHを供給する。ヘッド移動機構14は装着ヘッド15を移動させ、装着ヘッド15はノズル15Nにより部品BHを吸着する(図4)。基板カメラ16は作業装置制御部17に制御されて撮像動作を行う。基板カメラ16が撮像して得た画像データは、作業装置制御部17に送られる。
FIG. 5 is a block diagram showing the control system of the remote operation system 1 according to one embodiment of the present disclosure. The operation of each section of each working device 2 is controlled by a working device control section 17 (FIG. 3) which is a control section thereof. Specifically, the work device control unit 17 controls each operation of the transport conveyor 12, the tape feeder 13, the head moving mechanism 14, and the mounting head 15, as shown in FIG. As a result, the transport conveyor 12 transports and positions the board KB, and each tape feeder 13 supplies the component BH to the component supply position 13K. The head moving mechanism 14 moves the mounting head 15, and the mounting head 15 picks up the component BH with the nozzle 15N (FIG. 4). The board camera 16 is controlled by the work device control section 17 to perform an imaging operation. Image data captured by the board camera 16 is sent to the work device control section 17 .
作業装置2が部品装着作業を行う場合には先ず、搬送コンベア12を作動させて基板KBを搬入し、作業位置に位置決めする。基板KBが作業位置に位置決めされたらヘッド移動機構14を作動させて装着ヘッド15を基板KBの上方に移動させ、基板カメラ16に基板KBを撮像させる。基板カメラ16が基板KBを撮像したらその画像に基づいて基板KBを認識する。
When the work device 2 performs the component mounting work, first, the transport conveyor 12 is operated to carry in the board KB and position it at the work position. When the substrate KB is positioned at the working position, the head moving mechanism 14 is operated to move the mounting head 15 above the substrate KB, and the substrate camera 16 is caused to take an image of the substrate KB. When the board camera 16 takes an image of the board KB, the board KB is recognized based on the image.
作業装置2は、基板KBを認識したら、テープフィーダ13により部品BHを供給させつつ、装着ヘッド15に部品ピックアップ動作と部品装着動作を行わせる。装着ヘッド15は、部品ピックアップ動作ではテープフィーダ13が供給する部品BHをノズル15Nにより吸着(ピックアップ)し、部品装着動作では基板KB上の所定の位置にピックアップした部品BHを装着する。
When the work device 2 recognizes the board KB, it causes the tape feeder 13 to feed the component BH and causes the mounting head 15 to perform component pick-up and component mounting operations. The mounting head 15 sucks (picks up) the component BH supplied by the tape feeder 13 with the nozzle 15N in the component picking operation, and mounts the picked up component BH at a predetermined position on the board KB in the component mounting operation.
作業装置2は、装着ヘッド15に部品ピックアップ動作と部品装着動作を繰り返し行わせることによって基板KBに装着すべき全ての部品BHを装着したら、搬送コンベア12を作動させて基板KBを作業位置から搬出する。これにより基板KBの1枚当たりの部品装着作業が終了する。
After mounting all the components BH to be mounted on the board KB by causing the mounting head 15 to repeatedly perform the component pick-up operation and the component mounting operation, the work device 2 operates the conveyer 12 to carry out the board KB from the work position. do. This completes the component mounting work for each board KB.
作業装置2は上記のような手順で部品装着作業を実行するが、その過程において何らかのエラーが発生することがある。本実施の形態におけるリモート操作システム1では、作業ライン2Lを構成する作業装置2にエラーが発生した場合には、そのエラーをリモート監視部4からのリモート操作で解消することができるようになっている。以下、その説明を行う。
The work device 2 performs the component mounting work according to the procedure described above, but some kind of error may occur in the process. In the remote operation system 1 according to the present embodiment, when an error occurs in the work device 2 constituting the work line 2L, the error can be resolved by remote operation from the remote monitoring unit 4. there is The explanation is given below.
図5において、各作業装置2の作業装置制御部17は、エラー検出部21、エラー情報取得部22、エラー情報送信部23および解消操作情報受信部24を備えている。エラー検出部21は、作業装置2内に何らかのエラーが発生した場合にはこれを検出し、作業装置2の全部または一部の動作を中断させる。エラー情報取得部22は、エラー検出部21によって検出されたエラーの発生箇所(エラー発生箇所)を特定し、発生したエラーの情報(種別およびその内容)を「エラー情報」として取得する。
5, the work device control unit 17 of each work device 2 includes an error detection unit 21, an error information acquisition unit 22, an error information transmission unit 23, and a cancellation operation information reception unit 24. The error detection unit 21 detects any error that occurs in the work device 2 and interrupts the operation of all or part of the work device 2 . The error information acquisition unit 22 identifies the error occurrence location (error occurrence location) detected by the error detection unit 21, and acquires information (type and content) of the error that has occurred as "error information."
エラー情報取得部22は、エラーの発生箇所が基板カメラ16によって撮像可能である場合には、ヘッド移動機構14を作動させて基板カメラ16をエラー発生箇所の上方に移動させ、エラー発生箇所を基板カメラ16に撮像させる。例えば、装着ヘッド15が、或るテープフィーダ13からの部品BHの吸着に一定回数連続して失敗していた場合には、そのテープフィーダ13の部品供給位置13Kをエラー発生箇所として特定し、部品供給位置13Kの静止画像または動画を基板カメラ16に撮像させる。
If the board camera 16 can capture an image of the error occurrence location, the error information acquisition unit 22 operates the head moving mechanism 14 to move the board camera 16 above the error occurrence location, and moves the error occurrence location to the substrate. An image is captured by the camera 16 . For example, if the mounting head 15 fails to pick up a component BH from a certain tape feeder 13 a fixed number of times in succession, the component supply position 13K of the tape feeder 13 is specified as the error occurrence location, and the component A still image or moving image of the supply position 13K is taken by the substrate camera 16. FIG.
エラー情報送信部23は、エラー情報取得部22が取得したエラー情報をサーバ3に送信する(図2)。エラー発生箇所が基板カメラ16によって撮像された場合には、そのエラー発生箇所の画像データ(静止画あるいは動画データ)は、エラー情報の一部としてサーバ3に送信される。
The error information transmission unit 23 transmits the error information acquired by the error information acquisition unit 22 to the server 3 (Fig. 2). When the error occurrence location is imaged by the board camera 16, the image data (still image or moving image data) of the error occurrence location is sent to the server 3 as part of the error information.
図5において、サーバ3は記憶部31、選択部32、転送部33、ステータス変更部34およびステータス情報送信部35を備えている。記憶部31には作業装置2から送信されたエラー情報のほか、種々のデータや情報が随時記憶される。
5, the server 3 includes a storage section 31, a selection section 32, a transfer section 33, a status change section 34, and a status information transmission section 35. In addition to the error information transmitted from the work device 2, the storage unit 31 stores various data and information at any time.
選択部32は、作業装置2から送信されたエラー情報の送信(転送)先として、オペレータOPが作業装置2に発生したエラーを解消するための操作(エラー解消操作)を行うことができる状態にあるリモート監視部4を選択する。ここで、「オペレータOPがエラー解消操作を行うことができる状態にあるリモート監視部4」とは、具体的には、リモート監視部4を選択する時点でオペレータOPが操作席に在席しており、かつそのオペレータOPがエラー解消操作を行っていない状態にあるリモート監視部4をいう。
The selection unit 32 is in a state in which the operator OP can perform an operation (error elimination operation) for resolving an error that has occurred in the work device 2 as a transmission (transfer) destination of the error information transmitted from the work device 2. A certain remote monitoring unit 4 is selected. Here, "the remote monitoring unit 4 in a state where the operator OP can perform an error resolution operation" specifically means that the operator OP is present at the operation seat at the time the remote monitoring unit 4 is selected. The remote monitoring unit 4 is in a state where the operator OP is not performing an error elimination operation.
選択部32は、エラー情報の送信先の候補となるリモート監視部4が複数ある場合には、予め定めた基準に基づいて1つのリモート監視部4を選択する。例えば、「最後に行ったエラー解消操作の終了時から最も時間が経過しているリモート監視部4を優先的に選択する」という基準が設定されている場合には、候補となっている複数のリモート監視部4のうち、最後に行ったエラー解消処理の終了時から最も時間が経過しているリモート監視部4をエラー情報の送信先として選択する。
When there are a plurality of remote monitoring units 4 that are candidates for error information transmission destinations, the selecting unit 32 selects one remote monitoring unit 4 based on a predetermined criterion. For example, if a criterion is set to "preferentially select the remote monitoring unit 4 for which the longest time has elapsed since the end of the last error resolution operation", a plurality of candidate Of the remote monitoring units 4, the remote monitoring unit 4 for which the longest time has elapsed since the end of the last error resolution process is selected as the transmission destination of the error information.
記憶部31には、各リモート監視部4のステータスを示す監視部ステータス情報が記憶される。各リモート監視部4のステータスはオペレータOPのアクションによって変化する。各リモート監視部4のステータスが変化したときには,記憶部31に記憶されている監視部ステータス情報は、ステータス変更部34によって変更される。選択部32は、エラー情報の送信先となるリモート監視部4を選択するときには、その選択時に記憶部31に記憶されている各リモート監視部4の監視部ステータス情報に基づいて選択を行う。
Monitoring unit status information indicating the status of each remote monitoring unit 4 is stored in the storage unit 31 . The status of each remote monitoring unit 4 changes depending on the action of the operator OP. When the status of each remote monitoring unit 4 changes, the monitoring unit status information stored in the storage unit 31 is changed by the status changing unit 34 . When selecting the remote monitoring unit 4 to which the error information is to be sent, the selecting unit 32 selects based on the monitoring unit status information of each remote monitoring unit 4 stored in the storage unit 31 at the time of selection.
転送部33は、選択部32により選択された1つのリモート監視部4に、作業装置2から送信されたエラー情報を送信(転送)する。これにより作業装置2からサーバ3に送られてきたエラー情報は、複数のリモート監視部4のうちの1つに送信(転送)される。
The transfer unit 33 transmits (transfers) the error information transmitted from the work device 2 to one remote monitoring unit 4 selected by the selection unit 32 . As a result, the error information sent from the working device 2 to the server 3 is sent (transferred) to one of the plurality of remote monitoring units 4 .
図1において、複数のリモート監視部4それぞれは、例えばパーソナルコンピュータから構成されている。各リモート監視部4は、図5にも示すように、リモート監視制御部41、ディスプレイ装置42および入力装置43を備えている。
In FIG. 1, each of the plurality of remote monitoring units 4 is composed of, for example, a personal computer. Each remote monitoring section 4 includes a remote monitoring control section 41, a display device 42 and an input device 43, as also shown in FIG.
図5において、リモート監視制御部41は、エラー情報受信部51、エラー情報表示制御部52、解消操作情報送信部53、在席/離席入力制御部54および在席/離席情報通知部55を備えている。エラー情報受信部51はサーバ3から送信(転送)されたエラー情報を受信し、エラー情報表示制御部52は、エラー情報受信部51が受信したエラー情報をディスプレイ装置42に表示させる。
5, the remote monitoring control unit 41 includes an error information receiving unit 51, an error information display control unit 52, a clearing operation information transmitting unit 53, a presence/absence input control unit 54, and a presence/absence information notification unit 55. It has The error information receiving section 51 receives error information transmitted (transferred) from the server 3 , and the error information display control section 52 causes the display device 42 to display the error information received by the error information receiving section 51 .
図6Aおよび図6Bは、本開示の一実施の形態におけるリモート操作システム1が備えるリモート監視部4のディスプレイ装置42に表示されるエラー発生箇所の画像の一例を示す図である。図6Aは、エラー情報表示制御部52によってディスプレイ装置42に表示されたエラー情報の一例としてのエラー発生箇所の画像GZを示している。図6Aに示す画像は、前述した部品BHの吸着ミスが発生した場合におけるテープフィーダ13の部品供給位置13Kを含む領域を映し出したものであり、エラー発生箇所の画像の中心位置は、ノズル15Nの下端の位置(ノズル下端位置KC)に一致している。エラー発生箇所の画像がディスプレイ装置42に表示されたら、オペレータOPは、その画像を見ながら、入力装置43からエラーの解消操作を行う。
6A and 6B are diagrams showing an example of an image of an error occurrence location displayed on the display device 42 of the remote monitoring unit 4 included in the remote operation system 1 according to the embodiment of the present disclosure. FIG. 6A shows an image GZ of an error occurrence location as an example of error information displayed on the display device 42 by the error information display control unit 52 . The image shown in FIG. 6A shows an area including the component supply position 13K of the tape feeder 13 when the component BH is picked up incorrectly as described above. It matches the lower end position (nozzle lower end position KC). When the image of the error occurrence location is displayed on the display device 42, the operator OP performs an error elimination operation from the input device 43 while viewing the image.
ノズル下端位置KCは本来、部品供給位置13Kと一致しているべきであるが、エラーが発生した状態の図6Aの画像では、ノズル下端位置KCと部品供給位置13Kとが一致していない。この場合、オペレータOPは、ノズル下端位置KCがテープフィーダ13の部品供給位置13Kに一致するように、部品吸着時における装着ヘッド15の位置を移動させる操作を行う。具体的には、図6Aの画像におけるノズル下端位置KCと部品供給位置13Kとの差分がキャンセルされて図6Bの状態になるように、部品吸着時における装着ヘッド15の位置を移動させるためのオフセット量(移動方向および移動量)を入力装置43から入力する。
The nozzle lower end position KC should originally match the component supply position 13K, but in the image of FIG. 6A in which an error has occurred, the nozzle lower end position KC and the component supply position 13K do not match. In this case, the operator OP moves the position of the mounting head 15 during component pickup so that the nozzle lower end position KC coincides with the component supply position 13K of the tape feeder 13 . Specifically, an offset for moving the position of the mounting head 15 during component pickup is performed so that the difference between the nozzle lower end position KC and the component supply position 13K in the image of FIG. 6A is canceled and the state of FIG. 6B is obtained. The amount (direction of movement and amount of movement) is input from the input device 43 .
解消操作情報送信部53は、入力装置43から入力されたエラーの解消操作の情報(解消操作情報)をサーバ3に送信する。サーバ3は解消操作情報を受信したら、その受信した解消操作情報を、転送部33からエラー情報の送信元である作業装置2に送信(転送)する(図2)。
The elimination operation information transmission unit 53 transmits to the server 3 the information of the error elimination operation input from the input device 43 (elimination operation information). When the server 3 receives the cancellation operation information, it transmits (transfers) the received cancellation operation information from the transfer unit 33 to the working device 2 that is the sender of the error information (FIG. 2).
サーバ3から解消操作情報が送信(転送)された作業装置2(エラー情報をサーバ3に送信した作業装置2)は、その解消操作情報を解消操作情報受信部24によって受信する。解消操作情報を受信した作業装置2の作業装置制御部17は、受信した解消操作情報に基づいてエラー発生箇所に関連する部位を作動させることによってエラーを解消する。エラーが解消したら作業装置制御部17は部品装着作業の中断状態を解除し、部品装着作業を再開させる。
The work device 2 to which the solution operation information has been sent (transferred) from the server 3 (the work device 2 that has sent the error information to the server 3) receives the solution operation information by the solution operation information receiving unit 24 . The work device control unit 17 of the work device 2 that has received the cancellation operation information cancels the error by activating the part related to the error occurrence location based on the received cancellation operation information. When the error is resolved, the work device control unit 17 cancels the interrupted state of the component mounting work and restarts the component mounting work.
このように本実施の形態におけるリモート操作システム1は、複数の作業装置2、サーバ3および複数のリモート監視部4を備えており、複数の作業装置2のいずれかにエラーが発生すると、その発生したエラーの情報をサーバ3が中継して複数のリモート監視部4のいずれかに転送し、そのエラーの情報(エラー情報)の転送を受けたリモート監視部4のオペレータOPはリモート監視部4からエラーを解消する操作(ジョブ)を行うようになっている。
As described above, the remote operation system 1 according to the present embodiment includes a plurality of working devices 2, a server 3, and a plurality of remote monitoring units 4. When an error occurs in any of the plurality of working devices 2, the error occurs. The server 3 relays the error information received and transfers it to one of the plurality of remote monitoring units 4, and the operator OP of the remote monitoring unit 4 receives the transfer of the error information (error information) from the remote monitoring unit 4. An operation (job) is performed to resolve the error.
図7は、本開示の一実施の形態におけるリモート操作システム1が備えるリモート監視部4のディスプレイ装置42に表示される在席/離席情報入力画面の一例を示す図である。本実施の形態におけるリモート操作システム1では、各リモート監視部4のオペレータOPは、担当するリモート監視部4の操作席から離席する場合にはそれをサーバ3に通知できるようになっている。オペレータOPは、担当するリモート監視部4の操作席から離席しようとする場合には、先ず、入力装置43から所定の操作を行う。これによりリモート監視制御部41の在席/離席入力制御部54は、例えば図7に示すような在席/離席情報入力画面60をディスプレイ装置42に表示させる。在席/離席情報入力画面60には在席ボタン61と離席ボタン62が設けられている。
FIG. 7 is a diagram showing an example of a presence/absence information input screen displayed on the display device 42 of the remote monitoring unit 4 included in the remote operation system 1 according to the embodiment of the present disclosure. In the remote operation system 1 according to the present embodiment, the operator OP of each remote monitoring unit 4 can notify the server 3 when leaving the operator's seat of the remote monitoring unit 4 in charge. When the operator OP intends to leave the operating seat of the remote monitoring unit 4 he is in charge of, he/she first performs a predetermined operation using the input device 43 . As a result, the presence/absence input control unit 54 of the remote monitoring control unit 41 causes the display device 42 to display a presence/absence information input screen 60 as shown in FIG. 7, for example. The presence/absence information input screen 60 is provided with a presence button 61 and an absence button 62 .
オペレータOPは、担当するリモート監視部4の操作席に着いたときには入力装置43から在席ボタン61を操作し、操作席を離れるときにはその前に入力装置43から離席ボタン62を操作する。オペレータOPは離席ボタン62を操作して操作席から離席した後、操作席に戻ってきて再度着席した場合には在席ボタン61を操作する。
The operator OP operates the presence button 61 from the input device 43 when he/she is seated at the operating seat of the remote monitoring unit 4 in charge, and operates the leave button 62 from the input device 43 before leaving the operating seat. After leaving the operating seat by operating the leaving button 62, the operator OP operates the presence button 61 when returning to the operating seat and taking a seat again.
オペレータOPは、リモート監視部4の操作席を離席してから操作席に戻ってくるまでの間は、一時的に新たなエラー情報に対応することができない状態になる。このためオペレータOPによる離席ボタン62の操作は、一時的に新たなエラー情報に対応することができない状態(対応不可状態)にあることを示す「対応不可入力」に相当し、離席ボタン62を備えたリモート監視部4の入力装置43は、対応不可入力を行う入力部として機能する。
The operator OP is temporarily unable to respond to new error information from the time he/she leaves the operator's seat of the remote monitoring unit 4 until he/she returns to the operator's seat. For this reason, the operation of the leave button 62 by the operator OP corresponds to an "unsupportable input" indicating that the operator is temporarily incapable of responding to new error information (unable to respond). , the input device 43 of the remote monitoring unit 4 functions as an input unit for performing an unsupportable input.
在席ボタン61と離席ボタン62は択一的に点灯するようになっており、直近に操作された方が点灯し、他方は消灯する。図7は、オペレータOPによって直近に操作された方の在席ボタン61が点灯し、他方の離席ボタン62が消灯している状態を示している。
The presence button 61 and the leave button 62 are designed to be lit alternatively, the one that was operated most recently lights up and the other goes out. FIG. 7 shows a state in which the presence button 61 that has been operated most recently by the operator OP is lit, and the other leave button 62 is not lit.
オペレータOPが在席ボタン61を操作すると、在席/離席情報通知部55は在席ボタン61を点灯させたうえで、在席ボタン操作情報をサーバ3に送信する。これによりリモート監視部4のオペレータOPが在席状態にあることがサーバ3に通知され、サーバ3はそのリモート監視部4にオペレータOPが在席していることを把握する。
When the operator OP operates the presence button 61 , the presence/absence information notification unit 55 lights the presence button 61 and transmits the presence button operation information to the server 3 . As a result, the server 3 is notified that the operator OP of the remote monitoring unit 4 is present, and the server 3 recognizes that the operator OP is present at the remote monitoring unit 4 .
一方、オペレータOPが離席ボタン62を操作すると、在席/離席情報通知部55は離席ボタン62を点灯させたうえで、離席ボタン操作情報をサーバ3に送信する。これによりリモート監視部4のオペレータOPが離席状態にあることがサーバ3に通知され、サーバ3はそのリモート監視部4のオペレータOPが離席状態にあることを把握する。
On the other hand, when the operator OP operates the leave button 62 , the presence/absence information notification unit 55 lights the leave button 62 and transmits the leave button operation information to the server 3 . As a result, the server 3 is notified that the operator OP of the remote monitoring unit 4 is away from the seat, and the server 3 recognizes that the operator OP of the remote monitoring unit 4 is away from the seat.
このように本実施の形態において、各リモート監視部4が備える在席/離席情報通知部55は、オペレータOPが入力装置43から離席ボタン62の操作を行ったこと、すなわち入力部から対応不可入力を行ったことをサーバ3に通知する通知部となっている。
As described above, in the present embodiment, the presence/absence information notification unit 55 provided in each remote monitoring unit 4 responds to the fact that the operator OP has operated the absence button 62 from the input device 43, that is, from the input unit. This is a notifying section that notifies the server 3 that an invalid input has been made.
サーバ3は、リモート監視部4に送信したエラー情報、リモート監視部4から送られてくる在席ボタン操作情報、離席ボタン操作情報および解消操作情報に基づいて、そのリモート監視部4が「待機中」、「操作中」、「離席中」のいずれのステータスにあるかを判断し、各リモート監視部4についての処理ステータスを示す情報を監視部ステータス情報として記憶部31に記憶させる。処理ステータスが変更した場合にはステータス変更部34が処理ステータスを変更し、その変更後の処理ステータスを記憶部31に改めて記憶させる(上書きする)。
Based on the error information sent to the remote monitoring unit 4, the presence button operation information, the leaving button operation information, and the cancellation operation information sent from the remote monitoring unit 4, the server 3 causes the remote monitoring unit 4 to "wait." It determines which of the statuses of "in operation", "operating", and "away", and stores information indicating the processing status of each remote monitoring unit 4 in the storage unit 31 as monitoring unit status information. When the processing status is changed, the status changing unit 34 changes the processing status, and stores (overwrites) the changed processing status in the storage unit 31 again.
ここで「待機中」ステータスは、オペレータOPがリモート監視部4の操作席についている(在席中である)がエラー解消操作は行っていない状態、すなわちエラー情報が送信されてくるのを待機している状態を示すステータスである。「操作中」ステータスは、在席中のオペレータOPがエラー解消操作を行っている状態を示すステータスであり、「離席中」ステータスは、オペレータOPが操作席から離れている状態を示すステータスである。
Here, the "waiting" status is a state in which the operator OP is at the operation seat of the remote monitoring unit 4 (is present) but is not performing an error resolution operation, that is, waiting for error information to be sent. This status indicates that the The "operating" status is a status indicating that the operator OP who is present is performing an error elimination operation, and the "away" status is a status indicating that the operator OP is away from the operator's seat. be.
サーバ3のステータス変更部34は、リモート監視部4から最初に在席ボタン操作情報が送られてきたときには、そのリモート監視部4のステータスを「待機中」に設定して記憶部31に記憶させる。ステータスが「待機中」のリモート監視部4のオペレータOPは作業装置2に発生したエラーに対する解消操作を行うことができる状況にあるので、サーバ3はステータスが「待機中」であるリモート監視部4をエラー情報の送信先の候補とすることができる。
When the presence button operation information is first sent from the remote monitoring part 4, the status changing part 34 of the server 3 sets the status of the remote monitoring part 4 to "waiting" and stores it in the storage part 31. . Since the operator OP of the remote monitoring unit 4 whose status is "waiting" is in a situation where he can perform an operation to resolve the error that has occurred in the work device 2, the server 3 is in a state where the remote monitoring unit 4 whose status is "waiting" can be used as a candidate for the destination of the error information.
ステータスが「待機中」であるリモート監視部4にエラー情報が送信されたら、ステータス変更部34は、記憶部31に記憶されているそのリモート監視部4のステータスを「待機中」から「操作中」に変更して、記憶部31に改めて記憶(上書き)させる。そして、そのリモート監視部4から解消操作情報が送られてくるまでの間、そのリモート監視部4のステータスを「操作中」に維持する。ステータスが「操作中」であるリモート監視部4から解消操作情報が送られてきたら、ステータス変更部34は、記憶部31に記憶されているそのリモート監視部4のステータスを「操作中」から「待機中」に変更して、記憶部31に改めて記憶させる。
When the error information is sent to the remote monitoring unit 4 whose status is "waiting", the status changing unit 34 changes the status of the remote monitoring unit 4 stored in the storage unit 31 from "waiting" to "operating". ” and stores (overwrites) in the storage unit 31 again. Then, the status of the remote monitoring unit 4 is maintained as "in operation" until the remote monitoring unit 4 sends the cancellation operation information. When resolution operation information is sent from the remote monitoring unit 4 whose status is "in operation", the status change unit 34 changes the status of the remote monitoring unit 4 stored in the storage unit 31 from "in operation" to " "Standby" and stored again in the storage unit 31.
ステータス変更部34は、ステータスが「待機中」のリモート監視部4から離席ボタン操作情報が送られてきたときには、記憶部31に記憶されているそのリモート監視部4のステータスを「待機中」から「離席中」に変更して、記憶部31に改めて記憶させる。そして、ステータスが「離席中」であるリモート監視部4から在席ボタン操作情報が送られてきたら、サーバ3は記憶部31に記憶されているそのリモート監視部4のステータスを「離席中」から「在席中」に変更して、記憶部31に改めて記憶させる。
The status changing unit 34 changes the status of the remote monitoring unit 4 stored in the storage unit 31 to "waiting" when the leaving button operation information is sent from the remote monitoring unit 4 whose status is "waiting". is changed to "away from seat" and stored again in the storage unit 31. - 特許庁When the presence button operation information is sent from the remote monitoring unit 4 whose status is "Away", the server 3 changes the status of the remote monitoring unit 4 stored in the storage unit 31 to "Away". ' is changed to 'currently seated' and stored again in the storage unit 31 .
このように本実施の形態において、サーバ3は、在席/離席情報通知部55から対応不可入力としての離席ボタン62の操作が行われたことの通知があったリモート監視部4のステータスを、一時的に新たなエラー情報に対応することができない状態にある旨のステータス(ここでは「離席中」ステータス)に変更するようになっている。
As described above, in the present embodiment, the server 3 updates the status of the remote monitoring unit 4 that has been notified by the presence/absence information notification unit 55 that the absence button 62 has been operated as an unsupportable input. is changed to a status indicating that the user is temporarily unable to respond to new error information (here, "away" status).
ここで、リモート監視部4のステータスが「操作中」である場合には、そのリモート監視部4は一時的に新たなエラー情報に対応することができない状態となる。また、前述したように、リモート監視部4のステータスが「離席中」である場合にも、そのリモート監視部4は一時的に新たなエラー情報に対応することができない状態となる。このためサーバ3は、ステータスが「操作中」または「離席中」であるリモート監視部4には、作業装置2に発生したエラーのエラー情報を送信せず、ステータスが「待機中」であるリモート監視部4にエラー情報を送信する。
Here, if the status of the remote monitoring unit 4 is "in operation", the remote monitoring unit 4 is temporarily unable to respond to new error information. Also, as described above, when the status of the remote monitoring unit 4 is "away", the remote monitoring unit 4 is temporarily unable to respond to new error information. For this reason, the server 3 does not transmit error information of an error that has occurred in the work device 2 to the remote monitoring unit 4 whose status is "operating" or "away", and whose status is "waiting". Error information is sent to the remote monitoring unit 4 .
このように本実施の形態におけるリモート操作システム1において、サーバ3は、一時的に新たなエラー情報に対応することができない状態になっているリモート監視部4にはエラー情報を送信せず、エラー情報に対応可能なリモート監視部4にのみエラー情報を送信するようになっている。このためサーバ3がリモート監視部4に送信したエラーは、即時にオペレータOPによって対応され得る。
As described above, in the remote operation system 1 according to the present embodiment, the server 3 does not send error information to the remote monitoring unit 4, which is temporarily unable to respond to new error information. Error information is transmitted only to the remote monitoring unit 4 that can respond to the information. Therefore, an error sent by the server 3 to the remote monitoring unit 4 can be immediately dealt with by the operator OP.
また、本実施の形態において、サーバ3のステータス情報送信部35は、記憶部31に記憶された監視部ステータス情報を各リモート監視部4に送信し、各リモート監視部4はサーバ3から送信された監視部ステータス情報に基づいて、各リモート監視部4のステータスを表示するようになっている。各リモート監視部4のオペレータOPは、自身が操作するリモート監視部4のステータスについてはディスプレイ装置42に表示されるまでもなく自身で分かるので、ディスプレイ装置42には、少なくとも他のリモート監視部4のステータスが表示されれば足りる。
Further, in the present embodiment, the status information transmission unit 35 of the server 3 transmits the monitoring unit status information stored in the storage unit 31 to each remote monitoring unit 4, and each remote monitoring unit 4 receives the information sent from the server 3. The status of each remote monitoring unit 4 is displayed based on the monitoring unit status information. Since the operator OP of each remote monitoring unit 4 can know the status of the remote monitoring unit 4 he/she operates without displaying it on the display device 42, the display device 42 shows at least the status of the other remote monitoring units 4. It is enough if the status of is displayed.
図8A~図8Cは、本開示の一実施の形態におけるリモート操作システム1が備える複数のリモート監視部4それぞれのディスプレイ装置42に表示される監視部ステータス情報の一例を示す図である。例えば、リモート監視部4を3つ(リモート監視部「1」、リモート監視部「2」、リモート監視部「3」)有するリモート操作システム1において、リモート監視部「1」のステータスが「待機中」、リモート監視部「2」のステータスが「離席中」、リモート監視部「3」のステータスが「操作中」であったとする。このときリモート監視部「1」のディスプレイ装置42には、図8Aに示すように、リモート監視部「2」のステータスが「離席中」、リモート監視部「3」のステータスが「操作中」である旨の表示がなされる。また、リモート監視部「2」のディスプレイ装置42にはリモート監視部「1」のステータスが「待機中」、リモート監視部「3」のステータスが「操作中」である旨の表示がなされる(図8B)。また、リモート監視部「3」のディスプレイ装置42にはリモート監視部「1」のステータスが「待機中」、リモート監視部「2」のステータス「離席中」である旨の表示がなされる(図8C)。
8A to 8C are diagrams showing an example of monitoring unit status information displayed on the display device 42 of each of the plurality of remote monitoring units 4 included in the remote operation system 1 according to the embodiment of the present disclosure. For example, in the remote operation system 1 having three remote monitoring units 4 (remote monitoring unit "1", remote monitoring unit "2", remote monitoring unit "3"), the status of the remote monitoring unit "1" is "waiting , the status of the remote monitoring unit "2" is "away", and the status of the remote monitoring unit "3" is "operating". At this time, as shown in FIG. 8A, the display device 42 of the remote monitoring unit "1" shows that the status of the remote monitoring unit "2" is "away" and the status of the remote monitoring unit "3" is "operating". is displayed. Further, the display device 42 of the remote monitoring unit "2" displays that the status of the remote monitoring unit "1" is "waiting" and the status of the remote monitoring unit "3" is "operating" ( Figure 8B). In addition, the display device 42 of the remote monitoring unit "3" displays that the status of the remote monitoring unit "1" is "waiting" and the status of the remote monitoring unit "2" is "away" ( Figure 8C).
各リモート監視部4のオペレータOPは、自分が操作するリモート監視部4以外の他のリモート監視部4のステータスが「待機中」、「操作中」、「離席中」のいずれであるかが分かるので、オペレータOPは離席しようとした場合にその是非を判断して適切な対応をとることができる。例えば、自分が離席するとエラー情報に対応できるリモート監視部4が全くなくなってしまうと判断した場合には離席することを思いとどまり、次にサーバ3から送られてくるエラー情報に備えることができる。このように本実施の形態におけるリモート操作システム1では、オペレータOPは他のリモート監視部4のステータスに応じた適切な対応をとることができ、リモート操作システム1全体としてのエラー解消処理が滞ってしまう事態を防止することができる。
The operator OP of each remote monitoring unit 4 can determine whether the status of the other remote monitoring units 4 other than the remote monitoring unit 4 operated by the operator is "waiting", "operating", or "away from seat". Therefore, when the operator OP tries to leave the seat, he/she can judge whether it is right or wrong and take appropriate measures. For example, if it is determined that the remote monitoring unit 4 that can respond to error information will be completely lost when the user leaves his/her seat, he/she can refrain from leaving and prepare for the next error information sent from the server 3. . As described above, in the remote operation system 1 according to the present embodiment, the operator OP can take appropriate measures according to the status of the other remote monitoring units 4, and the error resolution processing of the remote operation system 1 as a whole is delayed. It is possible to prevent an accidental situation.
以上説明したように、本実施の形態におけるリモート操作システム1によれば、リモート監視部4の各オペレータOPは他のリモート監視部4のステータスがどのようになっているかが分かるので、他のリモート監視部4のステータスに応じた適切な行動をとることができる。このため例えば、自分が離席すると新たなエラー情報に対応することができるリモート監視部4が全くなくなってしまう状況ではオペレータOPは離席を思いとどまることができ、エラー解消処理が停滞してしまう事態を防止することができる。
As described above, according to the remote operation system 1 of the present embodiment, each operator OP of the remote monitoring unit 4 can know what the status of the other remote monitoring units 4 is. Appropriate actions can be taken according to the status of the monitoring unit 4. For this reason, for example, in a situation where the remote monitoring unit 4 that can respond to new error information disappears completely when the operator leaves his/her seat, the operator OP can refrain from leaving his/her seat, and the error resolution processing is delayed. can be prevented.
図9は、本開示の一実施の形態におけるリモート操作システム1が備えるリモート監視部4のディスプレイ装置42に表示される監視部ステータス情報の一例を示す図である。これまで本開示の実施の形態について説明してきたが、本開示は上述したものに限定されず、種々の変形等が可能である。例えば、上述の実施の形態では、送信先のリモート監視部4のディスプレイ装置42には、その送信先のリモート監視部4以外の他のリモート監視部4のステータスのみが表示されるようになっていたが、送信先のリモート監視部4のステータスが表示されるようになっていても構わない。この場合、リモート監視部「1」、リモート監視部「2」およびリモート監視部「3」それぞれのディスプレイ装置42には同じ画面(図9)が表示される。また、上述の実施の形態では作業装置2の例として部品装着装置を示したが、作業装置2は部品装着装置以外の他の作業装置であっても構わない。
FIG. 9 is a diagram showing an example of monitoring unit status information displayed on the display device 42 of the remote monitoring unit 4 included in the remote operation system 1 according to the embodiment of the present disclosure. Although the embodiments of the present disclosure have been described so far, the present disclosure is not limited to the above, and various modifications and the like are possible. For example, in the above-described embodiment, the display device 42 of the destination remote monitoring unit 4 displays only the status of the other remote monitoring units 4 other than the remote monitoring unit 4 of the destination. However, the status of the destination remote monitoring unit 4 may be displayed. In this case, the same screen (FIG. 9) is displayed on the display devices 42 of the remote monitoring unit "1", the remote monitoring unit "2", and the remote monitoring unit "3". Further, in the above-described embodiment, a component mounting device is shown as an example of the working device 2, but the working device 2 may be a working device other than the component mounting device.
各オペレータが他のリモート監視部のステータスに応じた適切な行動をとることができ、エラー解消処理が停滞してしまう事態を防止することができるリモート操作システムを提供する。
