[Outline of work support system 1]
FIG. 1 is a diagram illustrating an example of a functional outline of the work support system 1 of the present embodiment. The work support system 1 is a system that supports work in a factory or the like. The work support system 1 displays an image P1 indicating the relationship between the equipment and the worker on a display or the like based on information such as a production plan, equipment operation status, and worker dynamics. Further, the work support system 1 issues a work instruction to the worker and performs various analyzes on the work based on the relationship between the facility and the worker. The work support system 1 supports work in a factory or the like by providing such a function.

FIG. 2 is a diagram illustrating an example of a factory FT to which the work support system 1 of the present embodiment is applied. The factory FT in this example has five districts of N1, N2, N3, S1 and S2. In the N1 district, a processing machine A (Fcl_01) and a sensor Bc_1 are installed. The processing machine A is provided with a mold MD2. In the N2 area, a processing machine B (Fcl_02) and a sensor Bc_2 are installed. In the N3 area, there are a sensor Bc_3 and a mold place.

Further, the automatic guided vehicle AGV is in the vicinity of the sensor Bc_6.

  The work support system 1 provides, for example, the following two functions to support the work of the factory FT. The first function is a “work schedule schedule cause determination function”. The second function is an “operator call function when a pre-existence deviation occurs”.

The first work schedule prejudice divergence cause determination function is used to determine the cause of a lag or advance, that is, the cause of a preparatory divergence when the actual work is delayed or advanced with respect to a predetermined work schedule. It is a function to do.
Possible causes of the deviation are, for example, “the worker OP is taking time to set up the equipment FCL”, or “the worker OP has taken time for other work and cannot set up the equipment FCL”. There is.

The operator call function when the second pre-real deviation occurs is a function for notifying an appropriate operator OP when a pre-real deviation occurs for a certain facility FCL. Upon receipt of this notification, the worker OP performs work support for the equipment FCL in which a pre-real deviation has occurred. Here, the appropriate worker OP is a worker OP in the vicinity of the facility FCL or a worker OP who is familiar with the work of the facility FCL.
A functional configuration of the work support system 1 that realizes these functions will be described with reference to FIG.

[Functional configuration of work support system 1]
FIG. 3 is a diagram illustrating an example of a functional configuration of the work support system 1 of the present embodiment. The work support system 1 includes an arithmetic device 10, an equipment information storage unit 20, an operator behavior acquisition unit 30, a schedule information storage unit 40, an equipment operation status acquisition unit 50, a cause information storage unit 60, and a communication unit. 70 and a display unit 80.
The facility information storage unit 20 stores facility information FC. An example of the facility information FC will be described with reference to FIG.

  FIG. 4 is a diagram illustrating an example of the facility information FC of the present embodiment. In the equipment information storage unit 20, the equipment ID, equipment name, and installation position are associated with each other and stored as equipment information FC. The equipment ID is information for uniquely identifying the equipment FCL assigned to the equipment FCL. The equipment name is the name of the equipment FCL. The equipment FCL includes machines such as processing machines and jigs and tools such as dies. The installation position is a place in the factory where the equipment FCL is installed.

Returning to FIG. 3, the worker dynamics acquisition unit 30 acquires information indicating the dynamics of the worker OP. The information indicating the dynamics of the worker OP includes the worker's OP identification number, position, moving speed, direction, posture, action, health condition, role, and the like. For example, the worker behavior acquisition unit 30 may include the sensor Bc. In this case, the sensor Bc of the worker dynamics acquisition unit 30 acquires the identification number and position of the worker OP as information indicating the dynamics of the worker OP.
Note that the worker behavior acquisition unit 30 is not limited to the one provided with the sensor Bc, but may be provided with a device that can acquire the behavior of the worker OP, such as a camera, a microphone, and a beacon.

  FIG. 5 is a diagram illustrating an example of the schedule information SC of the present embodiment. In the schedule information storage unit 40, the work ID, equipment ID, work content, and work time are associated with each other and stored as schedule information SC. The work ID is information uniquely assigned to each work and identifying the work. The work content is the content of work performed by the facility FCL and the worker OP. The work contents include, for example, die replacement by the operator OP, input of the workpiece into the equipment FCL, processing of the workpiece by the equipment FCL, removal of the workpiece from the equipment FCL by the operator OP, cleaning, preparation for start-up, and the like. . The work time is a scheduled time for each work.

  Returning to FIG. 3, the facility operating status acquisition unit 50 acquires operating status information indicating the operating status of the facility FCL. The equipment operation status acquisition unit 50 is, for example, a computer or sensor that controls the operation of the equipment FCL.

  FIG. 6 is a diagram illustrating an example of the cause information CC of the present embodiment. The cause information storage unit 60 stores an example of the cause of the deviation of the work schedule. Specifically, in the cause information storage unit 60, a cause ID and a cause name are associated with each other and stored as cause information CC. The cause ID is information uniquely assigned to the cause name and identifying the cause name. The cause name is the name of the cause of the deviation of the work schedule. The names of the causes include, for example, power failure, machining mistake, mold breakage, broken tool, forgetting work, and engaging in other work.

[Functional configuration of arithmetic device 10]
Returning to FIG. 3, the arithmetic device 10 includes, for example, a CPU (Central Processing Unit), a situation information generation unit 110, a probable deviation determination unit 120, a deviation cause determination unit 130, an operator extraction unit 140, The output control unit 150 is provided as the functional unit.

The situation information generation unit 110 generates the situation information SI based on the facility information FC stored in the facility information storage unit 20 and the worker information WI acquired by the worker behavior acquisition unit 30. The status information SI is information indicating the relationship between the status of the equipment FCL and the status of the worker OP. Specifically, the status information SI includes relative position information RPI indicating the relative position between the equipment FCL and the worker OP. This relative position information RPI indicates the straight line distance, movement distance, estimated arrival time, and direction between the facility FCL and the worker OP. The travel distance and the estimated arrival time may be calculated based on the distance and travel time when avoiding other facilities and obstacles existing between the facility FCL and the worker OP.
In this case, the situation information generation unit 110 displays information such as the distance between the equipment FCL and the worker OP, whether the worker OP is facing the equipment FCL, or the back of the equipment FCL. Generate as When the equipment FCL has an operation panel, a processing room in which workpieces are installed, etc., the situation information generation unit 110 determines whether the operator OP is at the operation panel position of the equipment FCL or at the processing room position. Information to be shown is generated as situation information SI.
That is, the situation information generation unit 110 generates the relative position information RPI indicating the relative position between the equipment FCL and the worker OP as the situation information SI.

  Further, the situation information SI may include correspondence information CI indicating the correspondence between the operation status of the equipment FCL and the role of the worker OP. The operating status of the equipment FCL is a status such as whether the equipment FCL is operating, whether the equipment FCL has a failure, and the type of failure. The role of the worker OP is a production worker who uses the facility FCL to produce a product, a facility maintenance worker who is responsible for the maintenance of the facility FCL, or the like. Further, when a production worker or equipment maintenance worker has a position corresponding to skill, knowledge, proficiency level, etc., the position of the worker OP includes this position. In this case, when a failure has occurred in the facility FCL, the status information generation unit 110 generates correspondence information CI that associates the failure of the facility FCL with the worker OP who is a facility maintenance worker. That is, when the equipment FCL has a failure, the status information generation unit 110 generates correspondence information CI that the worker OP, who is the equipment maintenance worker, is suitable among the workers OP.

  Predictive divergence determination unit 120 determines the degree of divergence of actual operation of equipment FCL based on the operation schedule of equipment FCL and the operating status of equipment FCL. Specifically, the actual deviation determination unit 120 acquires the schedule information SC from the schedule information storage unit 40 and the facility operation status OS from the facility operation status acquisition unit 50. Predictive divergence determination unit 120 compares the acquired schedule information SC with the facility operating status OS to determine the degree of divergence of premise. Predictive divergence determination unit 120 determines a preparative divergence degree for each of the plurality of facilities FCL. The predicted actual deviation determination unit 120 determines that the predicted actual deviation is large when the actual deviation exceeds a predetermined threshold. Predictive divergence determination unit 120 outputs the facility ID of facility FCL that has been determined to have a large degree of preparative divergence to deviance cause determination unit 130 and operator extraction unit 140.

  The divergence cause determination unit 130 causes the status information generation unit 110 to generate the cause of the actual divergence of the determination target facility FCL that has been determined by the predicted / real divergence determination unit 120 to have a large degree of actual divergence among the plurality of facilities FCL. The determination is made based on the relative position information RPI. Specifically, the divergence cause determination unit 130 acquires the facility ID of the facility FCL to be determined from the pre-existence divergence determination unit 120. The divergence cause determination unit 130 acquires the status information SI for the acquired equipment ID from the status information generation unit 110. Further, the divergence cause determination unit 130 acquires cause information CC from the cause information storage unit 60. The divergence cause determination unit 130 determines the cause of the schedule divergence for the facility FCL based on the acquired status information SI and the cause information CC.

Specifically, when the operator OP is working in the vicinity of the equipment FCL and the equipment FCL is stopped, the cause of the stop is estimated to be a processing error, damage to the mold, tool breakage, etc. The When the facility FCL is stopped, the divergence cause determination unit 130 determines that the cause is, for example, “processing error” when the situation information SI indicates that the operator OP is working near the facility FCL.
That is, when the relative position information RPI indicates that the distance between the determination target facility FCL and the worker OP is relatively close, the divergence cause determination unit 130 causes the worker OP with respect to the determination target facility FCL. It is determined that it is caused by the work.

In addition, when the operator OP is working away from the equipment FCL and the equipment FCL is stopped, the cause of the stop is that the operator OP forgets to take out the workpiece that has been processed, or the operator OP performs other work. It is presumed that they are engaged in. When the facility FCL is stopped, the divergence cause determination unit 130 determines that the cause is “forgotten work”, for example, when the situation information SI indicates that there is no worker OP working near the facility FCL. .
That is, when the relative position information RPI indicates that the distance between the determination target facility FCL and the worker OP is relatively far, the divergence cause determination unit 130 determines that the cause is the work performed by the worker OP. It is determined that it is caused by a factor other than work for the determination target facility FCL. Factors other than this work include a failure of the determination target equipment FCL.

  The worker extraction unit 140 extracts a worker OP in charge of the work target facility FCL based on the facility information FC indicating the status of the facility FCL and the worker information WI indicating the status of the worker OP. Here, a case where the correspondence information CI indicating the correspondence between the operation status of the equipment FCL and the role of the worker OP is included in the status information SI will be described. In this case, the worker extraction unit 140 extracts a worker OP who is suitable for supporting the operating status of the facility FCL based on the role of the worker OP.

  The output control unit 150 outputs an image based on the situation information SI to the display unit 80. That is, the output control unit 150 displays an image based on the situation information SI. In addition, the output control unit 150 outputs information based on the situation information SI to the communication unit 70. The information based on the situation information SI includes call information for the worker OP extracted by the worker extraction unit 140.

The communication unit 70 communicates with terminal devices other than the arithmetic device 10. This terminal device includes a wireless communication terminal possessed by the worker OP. When the output control unit 150 outputs the call information for the worker OP, the communication unit 70 transmits the call information to the wireless communication terminal possessed by the worker OP.
The display unit 80 includes a liquid crystal display and displays an image output from the output control unit 150. In addition, instead of or in addition to the display unit 80, the work support system 1 may include a sound output unit that notifies by sound, a vibration unit that notifies by vibration, a light emitting unit that notifies by light, and the like.

[Operation of the arithmetic unit 10]
Next, an example of the operation of the arithmetic device 10 will be described with reference to FIG.
FIG. 7 is a diagram illustrating an example of the operation of the arithmetic device 10 according to the present embodiment. In this example, a case will be described in which the equipment FCL is stopped for some reason and a deviation occurs in the work schedule. Further, a case will be described as an example where, when there is no worker OP in the vicinity of the facility FCL, the arithmetic device 10 selects the worker OP appropriate for supporting the operation for resuming the operation of the facility FCL. In this example, an operator OP near the equipment FCL is selected as an appropriate operator OP.

  Predictive deviation determination unit 120 acquires schedule information SC from schedule information storage unit 40 (step S10). Predictive divergence determination unit 120 acquires the facility operation status OS from facility operation status acquisition unit 50 (step S20). Predictive deviation determination unit 120 compares schedule information SC and facility operating status OS, and determines whether or not there is a deviation in the probabilities of the work schedule (step S30). When it is determined that there is no divergence (step S30; NO), the actual deviation determination unit 120 returns the process to step S10. When it is determined that there is a divergence (step S30; YES), the actual deviation determination unit 120 advances the process to step S40. Here, a case where the work ID_PRC_03 shown in FIG. 5, that is, the work by the processing machine A is not completed at 11:45 will be described as an example. In this case, the predictive deviation determination unit 120 outputs the equipment ID_Fcl_01 of the processing machine A to the situation information generation unit 110.

  Note that the pre-real deviation determination unit 120 may weight the pre-real deviation determination for each work to be determined. For example, there is a case where the work to be determined is a work that has a relatively large influence on the entire work schedule when the premise is deviated. In this case, the preliminary deviation determination unit 120 may determine that there is a deviation in the prediction of the work schedule even if the degree of the preliminary difference is smaller than that of other work.

  The situation information generation unit 110 acquires the facility information FC from the facility information storage unit 20 (step S40). The facility information FC includes information indicating the position of the facility FCL. The situation information generation unit 110 acquires the worker information WI from the worker behavior acquisition unit 30 (step S50). The worker information WI includes information indicating the position of the worker OP. The worker status information generation unit 110 acquires the facility information FC for the facility FCL that has been determined to be deviated in step S30 from the acquired facility information FC. In this example, the equipment ID_Fcl_01 of the processing machine A is acquired from the preliminary actual deviation determination unit 120.

  The situation information generation unit 110 calculates the distance between the facility FCL and the worker OP by comparing the acquired facility information FC with the worker information WI (step S60). In this specific example, the situation information generation unit 110 calculates the distance between the processing machine A and each worker OP. In the specific example illustrated in FIG. 2, the situation information generation unit 110 calculates the distance between the processing machine A in which the schedule is different and the worker OP1 to the worker OP4.

  Next, the deviation cause determination unit 130 determines the cause of the work schedule deviation (step S70). Specifically, the divergence cause determination unit 130 acquires the distance between the processing machine A and each worker OP from the situation information generation unit 110. In the example shown in FIG. 2, the worker OP1 is closest to the processing machine A. Here, the operator OP1 is moving toward the processing machine A and does not operate the processing machine A. That is, in the situation shown in FIG. 2, the processing machine A does not have the operator OP. In this case, the divergence cause determination unit 130 determines that the cause of the stop of the processing machine A is not due to the worker OP, such as a work mistake of the worker OP. The divergence cause determination unit 130 outputs the determination result to the output control unit 150.

  Next, the worker extraction unit 140 extracts a worker OP that supports the work of the processing machine A whose work schedule is different from a plurality of workers OP (step S80). Specifically, the worker extraction unit 140 extracts the worker OP1 located closest to the processing machine A as a support worker based on the calculation result of the situation information generation unit 110. The worker extraction unit 140 outputs the extraction result to the output control unit 150.

  The output control unit 150 outputs the determination result of the cause by the deviation cause determination unit 130 to the display unit 80. Thereby, the cause of the deviation of the work schedule of the equipment FCL is displayed on the display unit 80. Here, the display unit 80 may display the situation of the equipment FCL and the worker OP in, for example, an overhead view or a plan view as shown in FIG.

Moreover, the output control part 150 outputs the extraction result by the worker extraction part 140 to the communication part 70 (step S90). In this specific example, the worker extraction unit 140 extracts the worker OP1 among the workers OP1 to OP4 as the support worker of the processing machine A. The output control unit 150 outputs information for instructing the operator OP1 to go to the position of the processing machine A to the communication unit 70. The communication unit 70 calls the worker OP.
The output control unit 150 may be connected to a broadcasting facility in a factory. In this case, the output control unit 150 may perform broadcasting for calling the worker OP.

  As described above, according to the arithmetic device 10, work support can be performed based on various situations of facilities and workers.
