Description

Remote operation system

Technical Field

The present disclosure relates to a remote operation system capable of eliminating errors generated on a line by remote operation from a remote monitoring section.

Background

Conventionally, a remote operation system is known that can eliminate an error in a line composed of a plurality of work devices by remote operation from a remote monitoring unit (for example, refer to patent document 1 below). In such a remote operation system, when an error occurs in a line, information of the error is transferred to one remote monitoring unit selected from a plurality of remote monitoring units, and an operator in charge of the remote monitoring unit requests an operation for eliminating the error (elimination process). In this case, in the case where there is no difference between the remote monitoring units, that is, there is no difference in the error elimination processing requested for any operator, the remote monitoring unit having the longest elapsed time since the last error elimination processing by the operator is often selected simply.

Disclosure of Invention

However, if the operator temporarily leaves the work station (the responsible remote monitoring unit) for some other reasons and performs the erroneous processing request while the operator is just leaving the work station, the erroneous processing work does not progress until the operator returns to the work station, and there is a possibility that not only the erroneous processing but also the erroneous removal processing of the entire line may be stopped.

To this end, an object of the present disclosure is to provide a remote operation system in which an erroneous cancellation job is not stagnated even if an operator temporarily leaves a work station.

The remote operation system of the present disclosure includes a line, a server, and a plurality of remote monitoring units, and transfers information of an error generated in the line to any one of the plurality of remote monitoring units via the server, and can eliminate the error generated in the line by remote operation by an operator of the remote monitoring unit that has received the transfer of the information of the error. The plurality of remote monitors each include: an on-duty setting unit for setting, as an on-duty condition, whether the remote monitoring unit for which the operator is responsible among the plurality of remote monitoring units is on-duty or off-duty; and a transmitting unit for transmitting the information of the on Shift status set by the on Shift status setting unit to the server. The server is provided with: a selecting unit that, when an error occurs in the line, identifies a remote monitoring unit for which the operator sets the on-duty status to an off-duty status at the point in time, and selects one remote monitoring unit from the remaining remote monitoring units excluding the identified remote monitoring unit; and a transfer unit that transfers the error information to the one remote monitoring unit selected by the selection unit.

According to the present disclosure, a remote operation system can be provided in which erroneous cancellation work is not stopped even when an operator temporarily leaves a work station.

Detailed Description

Embodiments of the present disclosure are described below with reference to the accompanying drawings. Fig. 1 is a remote operation system 1 in an embodiment of the present disclosure. The remote operation system 1 includes a line 2, a server 3, and a plurality of remote monitoring units 4. In the present embodiment, the work line 2 is configured by arranging a plurality of component mounting devices 2A, which are work devices for mounting components on a substrate KB, in series.

First, the component mounting apparatus 2A is explained. Fig. 2 is a main part side view of the component mounting device 2A constituting the line 2 of the remote operation system 1 in the embodiment of the present disclosure. As shown in fig. 2, the component mounting apparatus 2A includes a base 11, a conveyor 12, a tape feeder 13, a head moving mechanism 14, a mounting head 15, a substrate camera 16, and a component camera 17. The conveyor 12 extends horizontally on the base 11, and conveys the substrate KB horizontally from one end side toward the other end side.

Fig. 3 is a perspective view of a part of the component mounting apparatus 2A in an embodiment of the present disclosure. The tape feeder 13 pulls out the carrier tape CT wound around the reel RL by the sprocket 13S built in. In the carrier tape CT, a large number of components are enclosed in a row. The tape feeder 13 feeds the carrier tape CT to the end side of the conveyor 12 in an intermittent operation to continuously feed the component BH to the predetermined component feed position 13K.

The head moving mechanism 14 is constituted by, for example, an XY stage mechanism, and moves the head 15 in a horizontal plane. The mounting head 15 includes a plurality of suction nozzles 15N extending downward in the up-down direction. The mounting head 15 can make the lower end of each suction nozzle 15N suck the component BH supplied from the tape feeder 13.

In fig. 2 and 3, the substrate camera 16 is attached to the equipment head 15 in a posture in which the imaging optical axis is directed downward. The substrate camera 16 moves in the horizontal plane direction integrally with the equipment head 15.

In fig. 2, the component camera 17 is attached to the base 11 in a posture in which the imaging optical axis is directed upward. The component camera 17 picks up an image of the component BH from below when the head 15 having adsorbed the component BH moves upward on the substrate KB.

Fig. 4 is a block diagram showing a control system of the remote operation system 1 in an embodiment of the present disclosure. The mounting device control unit 18 (fig. 2), which is a control unit of the component mounting device 2A, controls the operations of the respective units of the component mounting device 2A (fig. 4). Specifically, the mounting device control unit 18 controls the conveyance operation of the substrate KB by the conveyor 12, and controls the feeding operation of the component BH to the component feeding position 13K by each tape feeder 13. The mounting device control unit 18 controls the head movement mechanism 14 to move the equipment head 15, and controls the equipment head 15 to suck the component BH by the suction nozzle 15N. The mounting device control unit 18 controls the imaging operation of the board camera 16 and the imaging operation of the component camera 17. The image data obtained by imaging the substrate camera 16 and the image data obtained by imaging the component camera 17 are sent to the mounting device control unit 18, respectively.

When performing a work (component mounting work) of mounting a component BH on a substrate KB, the component mounting apparatus 2A first carries the substrate KB into and positions the substrate KB at a work position by the conveyor 12. When the substrate KB is in the working position, the equipment head 15 is moved upward to pick up an image of the substrate KB by the substrate camera 16. The mounting device control unit 18 recognizes the substrate KB based on image data obtained by imaging the substrate KB by the substrate camera 16.

If the component mounting apparatus 2A recognizes the substrate KB, the tape feeder 13 continuously feeds the component BH to the component feeding position 13K, and the equipment head 15 moves between above the tape feeder 13 and above the substrate KB, and the equipment round is repeatedly performed. The equipment turn of the equipment head 15 is constituted by the following actions: an operation of sucking the component BH supplied from the tape feeder 13 through the suction nozzle 15N; the adsorbed component BH moves upward of the substrate KB on a path passing through an upper region of the component camera 17 (an imaging field of view of the component camera 17); and an operation of mounting the component BH on the substrate KB from above the substrate KB.

The component camera 17 captures an image of the component BH from below when the component BH passes through the imaging field, and the mounting device control unit 18 recognizes the component BH based on image data obtained by capturing the image of the component BH by the component camera 17. The recognition result of the component BH and the recognition result of the substrate KB are used in position correction or the like of the suction nozzle 15N when the mounting head 15 mounts the component BH to the substrate KB.

The equipping cycle by the equipping head 15 is repeated, and if all the required parts BH are equipped to the substrate KB, the conveyor 12 carries the substrate KB out of the working position. The conveyor 12 then newly carries in the next substrate KB.

The component mounting apparatus 2A performs the component mounting operation in the above-described steps, but in this process, some errors may occur. In the case where some errors are generated, the component mounting apparatus 2A interrupts all or a part of the component mounting operation, and enters an error elimination mode. Then, a portion (error occurrence portion) where an error occurs is specified, the substrate camera 16 is moved above the specified error occurrence portion, and the substrate camera 16 is made to image the error occurrence portion. For example, when the equipment head 15 continuously generates the suction omission of the component BH from a certain tape feeder 13, the component supply position 13K of the tape feeder 13 is determined as the error generation position, and the substrate camera 16 is made to image the error generation position. At this time, the substrate camera 16 captures a still image of the error generation site, or captures a moving image in real time.

The board camera 16 captures an image of the error occurrence region, and the mounting device control unit 18 of the component mounting device 2A that has caused the error transmits the obtained image data as error information to the server 3 (fig. 4). At this time, the error information (image data) transmitted from the mounting device control section 18 to the server 3 is still image data or moving image data of the error generation site.

In fig. 4, the server 3 is connected to each of the plurality of component mounting apparatuses 2A constituting the line 2 by wire or wirelessly. The server 3 receives error information (image data of an error generation site) transmitted from the component mounting device 2A that generated the error.

In fig. 4, the server 3 includes a storage unit 31, a selection unit 32, and a transfer unit 33. The storage unit 31 of the server 3 stores various data in advance, or stores various information such as error information transmitted from the component mounting apparatus 2A as needed.

The selecting unit 32 of the server 3 selects one of the remote monitoring units 4 as a transfer destination of the error information transmitted from the component mounting apparatus 2A that has generated the error. The transfer unit 33 of the server 3 transfers the error information to the one remote monitoring unit 4 selected by the selection unit 32 (fig. 4).

In fig. 1 and 4, the remote monitoring unit 4 is constituted by a personal computer, for example, and is connected to the server 3 by a wired or wireless connection. Each remote monitoring unit 4 includes a remote monitoring control unit 41, a display device 42, and an input device 43, and the remote monitoring control unit 41 includes a receiving unit 41a and a transmitting unit 41b. Each of the plurality of remote monitoring units 4 has an operator.

When the receiving unit 41a receives the error information transferred from the server 3, the remote monitoring unit 4 causes the error removal operation screen 51 (fig. 4) to display an image (still image or moving image) as the error information. The error correction operation screen 51 can be displayed on the display device 42 by the operator operating the input device 43.

When an image of the error occurrence portion (in the case of a moving image, display is started) is displayed on the error removal operation screen 51 of the display device 42, the operator looks at the image displayed on the display device 42 and performs an input operation (error removal operation) for removing an error from the input device 43. When the operator performs an error cancellation operation from the input device 43, a signal of the error cancellation operation (cancellation operation signal) is transmitted to the server 3 via the transmission unit 41b (fig. 4).

Fig. 5A and 5B are diagrams showing an example of the error-removal operation screen 51 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. 5A shows an example of the error-removal operation screen 51 displayed on the display device 42, which is an image (still image or moving image) obtained by capturing an image of an error-generating portion with the substrate camera 16. Here, an example of an image of an area including the component supply position 13K of the tape feeder 13 in the case where the suction omission of the component BH occurs is shown, and the center position of the image coincides with the position of the lower end of the suction nozzle 15N (suction nozzle lower end position KC).

The suction nozzle lower end position KC should be identical to the component supply position 13K (fig. 5B), but in the case where an error has occurred, as shown in fig. 5A, it is considered that the suction omission of the component BH occurs because the suction nozzle lower end position KC and the component supply position 13K do not coincide. In this case, the error eliminating operation performed by the operator from the remote monitoring section 4 is an operation of moving the position of the equipment head 15 at the time of component suction so that the nozzle lower end position KC coincides with the component supply position 13K of the tape feeder 13. Specifically, an operation of specifying an offset amount (a moving direction and a moving amount) for moving the position of the equipment head 15 at the time of component suction is made such that a difference between the suction nozzle lower end position KC and the component supply position 13K in the image of fig. 5A is canceled.

When the cancellation operation signal is transmitted from the remote monitoring unit 4 (fig. 4), the server 3 relays the cancellation operation signal and transmits the cancellation operation signal to the component mounting device 2A (fig. 4) that has generated the error. The mounting device control unit 18 of the component mounting device 2A that receives the erasure operation signal by relaying the same to the server 3 in this manner operates in accordance with the received error erasure operation. Thus, when the error is eliminated, the mounting device control unit 18 is configured to recover from the error, and restart the component mounting operation. Fig. 5B shows an image of an error occurrence portion in a state where an error is eliminated by an error elimination operation performed from the remote monitoring unit 4 on the image of fig. 5A.

As described above, the remote operation system 1 according to the present embodiment includes the line 2, the server 3, and the plurality of remote monitoring units 4, and transfers the information of the error generated in the line 2 (any one of the plurality of component mounting apparatuses 2A) to any one of the plurality of remote monitoring units 4 via the server 3, and the operator of the remote monitoring unit 4 that has received the transfer of the information of the error can cancel the error generated in the line 2 (the component mounting apparatus 2A) by performing an operation for canceling the error via the server 3.

However, in the remote operation system 1 in the present embodiment, the following can be prevented: since the error message is sent to the remote monitoring section 4 where the operator leaves the work station (i.e., leaves the work station from the remote monitoring section 4 in charge), the erroneous processing work does not progress until the operator returns to the work station. Further, it is possible to prevent a situation in which an operator spends a long time in eliminating an error due to the error handling of the type having a low processing skill requested by the operator. Hereinafter, a configuration for performing the functions of the remote operation system 1 will be described.

Fig. 6 is a diagram showing an example of the operator setting screen 52 of the display device 42 of the remote monitoring unit 4 of the remote operation system 1 according to the embodiment of the present disclosure. In the remote operation system 1 of the present embodiment, when an operator performs a predetermined operation from the input device 43 of the remote monitoring unit 4, for example, an operator own setting screen 52 as shown in fig. 6 is displayed on the display device 42. The upper layer of the operator setting screen 52 is an on-duty setting section 53, and the lower layer of the operator setting screen 52 is a coping with setting section 54 (see also fig. 4).

In fig. 6, the on duty setting section 53 includes an on duty button 61 and an off duty button 62. The on-duty setting unit 53 sets whether the operator is on-duty or off-duty in the remote monitoring unit 4 in charge of the operator itself as part of the on-duty.

The operator can operate the on-duty button 61 and the off-duty button 62 of the operator setting screen 52 at any time during his own work position, that is, during the on-duty of the responsible remote monitoring unit 4. The on duty button 61 and the off duty button 62 can be alternatively operated, and one of the most recently operated buttons by the operator is turned on and the other is turned off.

When the operator is at his or her work position, the off-duty button 62 is turned on (off-duty button 62 is turned off), and when the operator is away from the work position, the off-duty button 62 is operated and the off-duty button 62 is turned on (off-duty button 61 is turned off). Then, when the off-duty button 62 is operated and returns to the on-duty after leaving the on-duty, the on-duty button 61 is operated and the on-duty button 61 is turned on. Fig. 6 shows a state in which the operator has recently operated the on Shift button 61, and for this purpose, the on shift button 61 is turned on and the off shift button 62 is turned off. Since the off-duty button 62 is operated in a state where the operator is on duty in the responsible remote monitoring unit 4, it is needless to say that the off-duty button 62 is not in a state where the operator is off duty from the remote monitoring unit 4.

When the operator operates the on Shift button 61, the "on Shift message" is transmitted to the server 3 via the transmission unit 41b of the remote monitoring unit 4. On the other hand, when the operator operates the off duty button 62, the "off duty information" is transmitted to the server 3 via the transmission unit 41b. If the most recently transmitted one of the on-duty information and the off-duty information transmitted from each remote monitoring unit 4 is the on-duty information, the server 3 determines that the operator is on duty (on duty in the responsible remote monitoring unit 4), and if the most recently transmitted one is the off-duty information, the server 3 determines that the operator is off duty (off duty from the responsible remote monitoring unit 4).

In fig. 6, the coping with no-possibility setting unit 54 includes a coping with button 63 and an coping with impossible button 64 for each error category (here, "a", "B", and "C"). The coping with possibility setting unit 54 is a unit that is responsible for the operator of the remote monitoring unit 4 to set the coping with possibility per error type. Here, as the type of error, for example, as described above, in addition to the suction omission of the component BH of the mounting head 15, there may be mentioned an identification omission of the substrate KB passing through the substrate camera 16, an identification omission of the component BH passing through the component camera 17, and the like.

The operator can operate the coping button 63 and the coping button 64 at any time with respect to the type of each error of the operator self-setting screen 52 during the own work position, that is, during the time when the responsible remote monitoring unit 4 is on the job (but normally, the operator operates only 1 time during the work position). The coping button 63 and the coping button 64 can be operated alternatively for one error category, and one of the operators recently operated is turned on and the other is turned off.

The operator sets the coping with button 63 to the on state (sets the coping with button 64 to the off state) and sets the coping with button 64 to the on state (sets the coping with button 63 to the off state) in response to the type of the error determined to be coping with the operator. In addition, the case where the operator determines that the type of an error cannot be handled is a case where the operator cannot handle the error at all or the operator can handle the error but it is considered that a lot of time is obviously required. Fig. 6 shows a state in which the operator has operated the coping-button 63 for the category "a" and the category "C" and has operated the coping-button 64 for the category "B".

When the operator operates the coping with button 63 for a certain type of error, the "coping with information" is transmitted to the server 3 via the transmission unit 41b of the remote monitoring unit 4. On the other hand, when the operator operates the cannot cope with button 64 for a certain type of error, the "cannot cope with information" is transmitted to the server 3 via the transmission unit 41b. If the latest transmitted one of the information that can be handled and the information that cannot be handled for each error transmitted from each remote monitoring unit 4 is the information that can be handled, the server 3 determines that the operator can handle the error of the type, and if the latest transmitted one is the information that cannot be handled, the server 3 determines that the operator cannot handle the error of the type.

The server 3 creates on-duty information, which is a correspondence between each of the plurality of remote monitoring units 4 and an on-duty condition set by an operator who is responsible for each of the plurality of remote monitoring units 4 (specifically, a correspondence between one of on-duty information and off-duty information transmitted from each of the remote monitoring units 4 and the remote monitoring unit 4 that has been transmitted most recently), and stores the created on-duty condition information in the storage unit 31. The server 3 creates a correspondence relation between each of the plurality of remote monitoring units 4 and the type of error that cannot be handled by the operator who is responsible for the plurality of remote monitoring units 4 (specifically, a correspondence relation between the one of the type of information that can be handled and the information that cannot be handled, which is transmitted most recently, among the types of error that are transmitted from the respective remote monitoring units 4 and the remote monitoring units 4), that is, whether or not the information can be handled, and stores the created "information on whether or not to be handled" in the storage unit 31.

When an error occurs in the line (error information is transmitted from any one of the component mounting apparatuses 2A), the selection unit 32 of the server 3 selects one remote monitoring unit 4 as a transfer destination of the error information as described above. In this case, first, the remote monitoring unit 4 that sets the on-duty condition to off-duty (i.e., the operator leaves the work) at the time point when the error has occurred in the line 2 (the error information has been transmitted from the component mounting apparatus 2A that has generated the error) is determined based on the on-duty condition information stored in the storage unit 31. The selecting unit 32 determines the type of the remote monitoring unit 4 that the operator cannot handle the generated error based on the information on the availability of the storage unit 31.

That is, in the present embodiment, when an error occurs in the line 2, the selection unit 32 of the server 3 determines the remote monitoring unit 4 that the operator sets the on-duty condition to the off-duty condition at that point in time, and determines the type of remote monitoring unit 4 that the operator cannot cope with the error.

As described above, when the remote monitoring unit 4 in which the operator sets the on-duty condition to the off-duty condition is specified and the remote monitoring unit 4 of the type in which the operator cannot cope with the generated error is specified, the selection unit 32 of the server 3 selects one remote monitoring unit from the remaining remote monitoring units 4 excluding the specified remote monitoring unit 4 as the object of transmitting the error information of the generated error. Here, when one remote monitoring unit 4 is selected from the "remaining remote monitoring units", the selecting unit 32 selects, for example, a remote monitoring unit 4 for which the operator is idle at the time point when the error information is transmitted (the operator is not performing the error removal operation) and the operator who has elapsed the longest time from the last error removal operation.

As described above, when the selecting unit 32 selects one remote monitoring unit 4, the transmitting unit 33 of the server 3 transmits the error information to the selected remote monitoring unit 4. For this reason, since the error information is reliably sent to the remote monitoring unit 4 (on duty) of the operator at the work position, it is possible to prevent a situation in which the operator leaves the work position (off duty) without handling the error at all times and the time is left clear. Further, it is possible to prevent a situation in which the processing of the error takes too much time because the error information is sent to the remote monitoring unit 4 that is responsible for the operator who cannot cope with the type of the generated error.

Next, a flow of control performed by the control unit (mounting device control unit 18) of the component mounting device 2A constituting the line 2, the control unit (remote monitoring control unit 41) of the server 3, and the remote monitoring unit 4 will be described. Fig. 7 is a flowchart showing a flow of processing performed by the control unit of the component mounting device 2A of the line 2 of the remote operation system 1 according to the embodiment of the present disclosure.

Fig. 8 is a flowchart showing a flow of processing performed by the server 3 of the remote operation system 1 in the embodiment of the present disclosure. Fig. 9 is a flowchart showing a flow of processing performed by the control unit of the remote monitoring unit 4 of the remote operation system 1 according to the embodiment of the present disclosure.

In fig. 7, the mounting device control unit 18 of the component mounting device 2A checks whether or not an error has occurred in the component mounting device 2A to which it belongs at regular intervals (several seconds) (step ST 1), and when an occurrence of an error is detected, determines the occurrence location of the error (error occurrence location) (step ST 2). Then, all or a part of the component mounting operation is interrupted, and the error elimination mode is entered (step ST 3).

When the error elimination mode is entered, the mounting device control unit 18 moves the substrate camera 16 to a position above the error generation site, causes the substrate camera 16 to image the error generation site, and acquires the image data thereof as error information (step ST 4). Then, the acquired error information is transmitted to the server 3 (step ST 5).

In fig. 8, the server 3 checks whether or not there is transmission of error information from the line 2 (from any one of the plurality of component mounting apparatuses 2A) at regular intervals (several seconds) (step ST 11), and when it is detected that there is transmission of error information, it determines the component mounting apparatus 2A that transmitted the error information. The type of the transmitted error is grasped at the same time (step ST 12).

When the component mounting device 2A that transmitted the error information is determined and the type of the transmitted error is grasped, the server 3 determines the remote monitoring unit 4 (which is off-duty from the responsible remote monitoring unit 4) that the operator is off-duty based on the on-duty condition information that is received from the remote monitoring unit 4 and stored in the storage unit 31 (step ST 13). After (or before) this determination, similarly, the remote monitoring unit 4 that cannot handle the type of the transmitted error (generated in the component mounting apparatus 2A) is determined based on the information on whether or not the transmission from the remote monitoring unit 4 is received and stored in the storage unit 31 (step ST 14).

When the remote monitoring unit 4 at which the operator leaves the work position is determined in step ST13, and the remote monitoring unit 4 of the type for which the operator cannot cope with the error transmitted from the component mounting apparatus 2A is determined in step ST14, the server 3 selects one remote monitoring unit 4 to be the transfer destination of the error information from the remaining remote monitoring units 4 excluding the remote monitoring units 4 (step ST 15). When one remote monitoring unit 4 to be the transfer destination of the error information is selected in step ST15, the server 3 transfers the error information to the selected one remote monitoring unit 4 (step ST 16).

In fig. 9, the remote monitoring control unit 41 checks whether or not there is a transfer of error information from the server 3 at regular intervals (several seconds) (step ST 21), and when it detects that there is a transfer of error information from the server 3, causes the display device 42 to display the error information (image of the error occurrence site) transferred from the server 3 as an error removal operation screen 51 (step ST 22). Thus, the operator looks at the error information (image of the error generation site) displayed on the display device 42, and performs an operation of eliminating the error generated in the component mounting device 2A. When the operator performs an error removal operation, the remote monitoring control unit 41 transmits the operation signal (removal operation signal) to the server 3 (step ST 23).

After the error information is transferred to the remote monitoring unit 4 in step ST16 described above, the server 3 checks whether or not an erasure operation signal is transmitted from the remote monitoring unit 4 to which the error information has been transferred (step ST17 in fig. 8). When it is detected that the erasure operation signal is transmitted from the remote monitoring unit 4 that has transmitted the error information, the erasure operation signal is relayed and transmitted to the component mounting apparatus 2A (component mounting apparatus 2A that has generated the error) (step ST 18).

After transmitting the error message to the server 3 in step ST5 described above, the component mounting apparatus 2A checks whether or not the cancel operation signal is transmitted from the server 3 (step ST6 in fig. 7). Then, when it is detected that the cancel operation signal is transmitted from the server 3, a process according to the transmitted cancel operation signal is executed (step ST 7). Then, when the error is eliminated (step ST 8), the operation is released from the error elimination mode, and the operation returns to step ST1 after the interrupt state of the component mounting operation is released (step ST 9). If the error is not resolved in step ST8, a procedure waiting state is entered in which a new procedure is to be waited for, after some reporting operation is performed (step ST 10).

As described above, in the remote operation system 1 of the present embodiment, the plurality of remote monitoring units 4 each include: an on-duty setting unit 53 (on-duty button 61 and off-duty button 62) for setting whether the remote monitoring unit 4 is on-duty or off-duty as an on-duty state by the operator of the remote monitoring unit 4; a coping with possibility setting unit 54 (coping with possibility button 63 and coping with impossible button 64 for each error type) for setting coping possibility for each error type by an operator in charge of the remote monitoring unit 4; the information of the on Shift condition set by the on Shift condition setting section 53 and the information of the availability of the operator for each error type set by the availability coping setting section 54 are transmitted to the transmitting section 41b of the server 3. The server 3 further includes: the selecting unit 32, when an error occurs in the line 2, determines the remote monitoring unit 4 that the operator has set the on-duty status to the off-duty status at that point in time, and determines the remote monitoring unit 4 that the operator cannot cope with the type of error occurring in the line 2, and selects one remote monitoring unit 4 from the remaining remote monitoring units 4 excluding the determined remote monitoring unit 4; and a transfer unit 33 for transferring the error information to the one remote monitoring unit 4 selected by the selection unit 32.

In the remote operation system 1 of the present embodiment, since the error information is not transferred to the remote monitoring unit 4 (off-duty) from which the operator leaves the work place, even when the operator temporarily leaves the work place (responsible remote monitoring unit 4) for some other reason, the error removal operation in the entire line 2 is not stopped. In the remote operation system 1 of the present embodiment, since the error information is not transferred to the remote monitoring unit 4 that is responsible for the operator who cannot handle the type of error generated, even when there is a personal difference in the skill of the operator in the error removal process, the error removal process in the entire line 2 is not stopped.

As described above, in the remote operation system 1 of the present embodiment, since the error information is not transferred from the server 3 to the remote monitoring unit 4 (off-duty) where the operator leaves the work place, even when the operator temporarily leaves the work place (responsible remote monitoring unit 4), the error elimination work in the entire work line 2 is not stopped, and the productivity of the work line 2 is not affected.

The embodiments of the present disclosure have been described so far, but the present disclosure is not limited to the foregoing, and various modifications and the like can be made. For example, the form of the operator setting screen 52 shown in fig. 6 is merely an example, and the form shown in fig. 6 may be not limited as long as the on-duty setting unit 53 and the coping with setting unit 54 are displayed. The on-duty condition setting unit 53 may be a unit that allows the operator to set the on-duty condition by the operator himself, and the coping with possibility setting unit 54 may be a unit that allows the operator to set coping with each error type by the operator himself, and is not necessarily displayed on the screen of the display device 42. In the above-described embodiment, the work line 2 is constituted by a plurality of component mounting devices 2A, but may be a work line constituted by devices other than the component mounting devices 2A.

Industrial applicability

The present disclosure provides a remote operation system in which erroneous cancellation work is not stagnated even if an operator temporarily leaves a work station.

Claims

1. A remote operation system comprises a line, a server, and a plurality of remote monitoring units, wherein information of an error generated in the line is transferred to any one of the plurality of remote monitoring units via the server, an operator of the remote monitoring unit receiving the transfer of the information of the error performs an operation for eliminating the error via the server, thereby eliminating the error generated in the line by remote operation,

the plurality of remote monitors each include:

an on-duty setting unit that sets, as an on-duty condition, whether an on-duty state or an off-duty state is set by an operator of each of the plurality of remote monitoring units in a remote monitoring unit that is in charge of the operator of the plurality of remote monitoring units; and

a transmitting unit configured to transmit the information of the on-duty status set by the on-duty status setting unit to the server,

the server is provided with:

a selecting unit configured to identify the remote monitoring unit for which the operator sets the on-duty status to an off-duty status at the time point when the error occurs in the line, and to select one remote monitoring unit from the remaining remote monitoring units excluding the identified remote monitoring unit; and

and a transfer unit configured to transfer the error information to the one remote monitoring unit selected by the selection unit.

2. The teleoperational system of claim 1, wherein,

the server has: a storage unit configured to store on-duty status information as a correspondence relationship between each of the plurality of remote monitoring units and the on-duty status set by an operator of each of the plurality of remote monitoring units,

the selection unit determines the remote monitoring unit that the operator sets the on-duty status to an off-duty state at a point in time when the error occurs in the line, based on the on-duty status information stored in the storage unit.
