The determination unit 222, the determination unit 223, and the display unit 224 are configured such that, for example, the hardware processor 201 performs arithmetic processing using the system program stored in the ROM 203, the operation program stored in the nonvolatile memory 205, and various data. This is achieved by

The storage unit 221 stores the relationship between the update cycle of at least one screen component displayed on the display screen and the state of the industrial machine 1.

The display screen is, for example, the display screen of the input/output device 3. The screen component is an image displayed on a display screen for presenting various information regarding the industrial machine 1 or accepting various information, and a program for displaying the image.

Screen components include, for example, a coordinate value display component that displays coordinate values that indicate the position of the control axis, an editor component that is used to edit an operation program, a feed rate display component that displays the feed rate of the control axis, and a component that displays the rotation speed of the main axis. It includes a spindle speed display component to display, and a modal display component to display modal commands that are in a valid state while the operation program is being executed.

The update cycle is the cycle at which information displayed by the screen component is updated. In other words, the screen component displays new information updated every update cycle. The update cycle is, for example, one of 16 [ms], 64 [ms], 128 [ms], and 256 [ms].

As mentioned above, the state of the industrial machine 1 means the operating state or setting state of the industrial machine 1. The operating states include an editing state where the operating program is being edited, an interrupt state where an interrupt is being executed, and an execution state where the operating program is being executed. The setting state includes a driving mode setting state in which one of the plurality of types of driving modes is set. For example, when the automatic operation mode is set, the state of the industrial machine 1 becomes the automatic operation mode setting state. The storage unit 221 stores the relationship between the update cycle and the state of the industrial machine 1 using, for example, a table.

FIG. 3 is a diagram illustrating an example of the relationship between the update cycle of screen components stored in the storage unit 221 and the state of the industrial machine 1. FIG. 3 is a diagram showing the relationship between the update cycle of screen components and the state of the industrial machine 1 in the MDI operation mode. The screen components include a coordinate value display component and an editor component. Furthermore, in the MDI operation mode, the states of the industrial machine 1 include an editing state in which the operating program is being edited, and an execution state in which the operating program is being executed.

The storage unit 221 stores that in the editing state, the coordinate value display component is updated at 128 [ms] and the editor component is updated at 16 [ms]. The storage unit 221 also stores that in the execution state, the coordinate value display component is updated at 16 [ms] and the editor component is updated at 128 [ms].

Note that while editing the operation program, the operator pays more attention to the editor component than to the coordinate value display component. Furthermore, during automatic operation, the operator pays more attention to the coordinate value display component than to the editor component. Therefore, in the edit state, the update cycle of the editor component is set short, and in the execution state, the update cycle of the coordinate value display component is set short. Here, we return to the explanation of FIG. 2.

The determining unit 222 receives information indicating the status of the industrial machine 1 from the control unit 21 and determines the status of the industrial machine 1. Information indicating the state of the industrial machine 1 is a signal output by the control device 2. For example, when the industrial machine 1 is set to the MDI operation mode, the control section 21 outputs an MDI operation mode signal to the determination section 222. Upon receiving the MDI operation mode signal, the determination unit 222 determines that the industrial machine 1 is set to the MDI operation mode. In other words, the determination unit 222 determines that the state of the industrial machine 1 is the MDI operation mode setting state.

Furthermore, when the industrial machine 1 is set to the MDI operation mode, an editor component that accepts manual operation program input is displayed on the display screen of the control device 2. At this time, the editor component is in a state in which it can accept command input from the operator, in other words, in a state in which it can edit the operating program. Therefore, upon receiving the MDI operation mode signal, the determining unit 222 determines that the operator in the industrial machine 1 is editing the operation program, that is, the state of the industrial machine 1 is in the editing state.

Furthermore, when the industrial machine 1 is set to the MDI operation mode and the editor component is in a state where it can accept command input from the operator, the control unit 21 outputs an editing signal indicating that it is in the editing state to the judgment unit. 222. The determining unit 222 may determine that the state of the industrial machine 1 is the editing state in response to receiving the editing signal.

The determining unit 223 determines the update cycle of the screen component based on the relationship between the update cycle of the screen component stored in the storage unit 221 and the state of the industrial machine 1 and the state of the industrial machine 1 determined by the determining unit 222. do.

For example, when the determining unit 222 determines that the state of the industrial machine 1 is the MDI operation mode setting state and the editing state, the determining unit 223 sets the update cycle of the coordinate value display component to 128 [ms] and the editor. Set the component update cycle to 16 [ms].

The display unit 224 displays at least one screen component based on the update cycle determined by the determination unit 223. Further, the display unit 224 receives information to be displayed on each screen component from the control unit 21.

FIG. 4 is a diagram showing an example of screen components displayed on the display screen. When the determining unit 223 determines the update cycle of the coordinate value display component C to be 128 [ms], the display unit 224 updates and displays the coordinate value display component C every 128 [ms]. Further, when the determining unit 223 determines the update cycle of the editor component E to be 16 [ms], the display unit 224 updates and displays the editor component E every 16 [ms]. Note that the display unit 224 may display an image indicating the update cycle on the display screen, as shown in FIG. 4. Further, the update period of other screen components shown in FIG. 4 may be, for example, 64 [ms], which is preset in the control device 2.

In the MDI operation mode, when editing of the operation program in the editor component E is completed and execution of the input operation program is started, the control unit 21 outputs an automatic operation start signal to the determination unit 222. When the determining unit 222 receives the automatic operation start signal, the determining unit 222 determines that the industrial machine 1 is in automatic operation, that is, the state of the industrial machine 1 is in the execution state.

When the determination unit 222 determines that the industrial machine 1 is in the MDI operation mode setting state and the execution state, the determination unit 223 sets the update cycle of the coordinate value display component C to 16 [ms] and changes the editor The update cycle of component E is determined to be 128 [ms].

The display unit 224 displays at least one screen component based on the update cycle determined by the determination unit 223.

Note that in the automatic operation mode, the operator pays the most attention to the feed rate display component and the spindle speed display component, then the coordinate value display component C, and does not pay much attention to the modal display component. Furthermore, in the manual operation mode, the operator focuses on the coordinate value display component C and does not pay much attention to the feed rate display component, the spindle speed display component, and the modal display component. Therefore, the update cycle of each screen component in the automatic operation mode setting state and the manual operation mode setting state is set as shown in FIG. 6.

When the industrial machine 1 is set to automatic operation mode, the control unit 21 outputs an automatic operation mode signal to the determination unit 222.

Further, when the determining unit 223 determines the update cycle of the modal display component M to be 128 [ms], the display unit 224 updates and displays the update cycle of the modal display component M every 128 [ms]. Note that the display unit 224 may display an image indicating the update cycle on the display screen, as shown in FIG. 10.

When an interrupt occurs during automatic operation of the industrial machine 1, the control unit 21 outputs an interrupt signal to the determination unit 222. When the determining unit 222 receives the interrupt signal, the determining unit 222 determines that the interrupt has been performed during automatic operation of the industrial machine 1. In other words, the determination unit 222 determines that the state of the industrial machine 1 is an interrupt state.

When the determining unit 222 determines that the industrial machine 1 is in the automatic operation mode setting state and in the interrupt state, the determining unit 223 sets the update cycle of the coordinate value display component C to 16 [ms]. , the update cycle of the feed speed display component F is determined to be 16 [ms], the update cycle of the spindle speed display component S is determined to be 16 [ms], and the update cycle of the modal display component M is determined to be 256 [ms].

The display unit 224 displays at least each screen component based on the update cycle determined by the determination unit 223.

FIG. 11 is a diagram showing an example of screen components displayed on the display screen. When the determining unit 223 determines the update cycle of the coordinate value display component C to be 16 [ms], the display unit 224 updates and displays the update cycle of the coordinate value display component C every 16 [ms]. Further, when the determining unit 223 determines the update cycle of the feed speed display component F to be 16 [ms], the display unit 224 updates and displays the update cycle of the feed speed display component F every 16 [ms]. .

Furthermore, when the determining unit 223 determines the update cycle of the modal display component M to be 256 [ms], the display unit 224 updates and displays the update cycle of the modal display component M every 256 [ms]. Note that the display unit 224 may display an image indicating the update cycle on the display screen, as shown in FIG. 11.

FIG. 12 is a flowchart showing an example of the flow of processing executed in the display device 22. In the display device 22, first, the determination unit 222 receives information indicating the state of the industrial machine 1 (step S1).

Next, the determining unit 222 determines the state of the industrial machine 1 based on the received information indicating the state of the industrial machine 1 (step S2).

Next, the determining unit 223 determines the update cycle of the screen component based on the relationship between the update cycle stored in the storage unit 221 and the state of the industrial machine 1 and the state of the industrial machine 1 determined by the determining unit 222. (Step S3).

Next, the display unit 224 displays the screen component based on the update cycle determined by the determining unit 223 (step S4), and the process ends. Note that the display unit 224 receives information indicating the state of the industrial machine 1, such as information indicating the position of a control axis, from the control unit 21 and displays it on each screen component.

As explained above, the display device 22 includes a storage unit 221 that stores the relationship between the update cycle of at least one screen component displayed on the display screen and the state of the industrial machine 1, and a storage unit 221 that determines the state of the industrial machine 1. a determining unit 223 that determines the update cycle based on the relationship stored in the storage unit 221 and the state of the industrial machine 1 determined by the determining unit 222; and a display unit 224 that displays at least one screen component based on the updated update cycle.

Therefore, the display device 22 can change the update cycle of screen components without burdening the operator with operations to specify screen components. Moreover, only the update period of the screen components that are noticed by the operator can be shortened depending on the state of the industrial machine 1. As a result, it is possible to prevent the processing load on the hardware processor 201 from becoming excessively large. Further, the display of the screen component that the operator is interested in can be updated smoothly.

Further, since the display device 22 shortens the update cycle of only the screen components that are noticed by the operator, the display of the screen components can be updated smoothly without using the expensive and highly functional hardware processor 201. . Therefore, the cost of the display device 22 can be reduced.

Furthermore, the determination unit 222 determines the state of the industrial machine 1 based on the signal output by the control device 2 that controls the industrial machine 1. The signal output by the control device 2 includes an operation mode signal indicating the operation mode of the industrial machine 1. Further, the signal output by the control device 2 includes an automatic operation start signal indicating that automatic operation of the industrial machine 1 has started. Further, the signal output by the control device 2 includes an interrupt signal indicating that an interrupt has been performed. Therefore, the display device 22 can change the update cycle of each screen component according to various states of the industrial machine 1.

Furthermore, the storage unit 221 stores the relationship between the update cycle and the state of the industrial machine 1 using a table. Therefore, the operator can easily understand, for example, the relationship between the update cycle and the state of the industrial machine 1.

Additionally, the display unit 224 displays an image indicating the update cycle on the display screen. Therefore, the operator can easily understand the update cycle of each screen component.

In the embodiment described above, the storage unit 221 stores the relationship between the update cycle of screen components and the state of the industrial machine 1. Further, the determining unit 222 determines the state of the industrial machine 1. Further, the determining unit 223 determines the update cycle based on the relationship stored in the storage unit 221 and the state of the industrial machine 1 determined by the determining unit 222.

However, the storage unit 221 may store the relationship between the update cycle of at least one screen component displayed on the display screen and the operator's actions. In this case, the determination unit 222 determines the operator's behavior based on information from an acquisition unit that monitors the operator's behavior and acquires information regarding the operator's behavior. The determining unit 223 determines the update cycle of each screen component based on the relationship stored in the storage unit 221 and the operator's behavior determined by the determining unit 222.

FIG. 13 is a block diagram showing an example of the function of the display device 22 in which the update cycle of screen components is determined based on the operator's actions. The block diagram shown in FIG. 13 differs from the control device 2 shown in FIG. 2 in that the acquisition unit 9 is connected to the display device 22. Therefore, the acquisition unit 9 and its related functions will be described here, and the description of the same functions as those described using FIG. 2 will be omitted.

The acquisition unit 9 monitors the operator's behavior and acquires information regarding the operator's behavior. The operator's behavior is, for example, which screen component out of a plurality of screen components the operator is paying attention to. That is, the acquisition unit 9 monitors the operator's line of sight.

The acquisition unit 9 is, for example, an imaging device. The imaging device is, for example, a camera. The acquisition unit 9 acquires information regarding the operator's behavior and sends it to the determination unit 222 . The information regarding the operator's behavior is, for example, line-of-sight information indicating the operator's line of sight.

The storage unit 221 stores the relationship between the update cycle of at least one screen component displayed on the display screen and the operator's actions.

FIG. 14 is a diagram illustrating an example of the relationship between the update cycle of screen components stored in the storage unit 221 and operator behavior. The storage unit 221 stores in a table the update cycle of the screen component that the operator is paying attention to, and the update cycle of screen components other than the screen component that the operator is focusing on. In other words, the storage unit 221 stores the update cycles of the screen parts that are ahead of the operator's line of sight and the update cycles of other screen parts.

When the operator is paying attention to the coordinate value display component C, the storage unit 221 updates the coordinate value display component C at 16 [ms], updates the feed speed display component F at 128 [ms], and displays the spindle speed. It is stored that the component S is updated at 128 [ms] and the modal display component M is updated at 128 [ms].

Furthermore, when the operator is paying attention to the feed rate display component F, the storage unit 221 updates the coordinate value display component C at 128 [ms], updates the feed speed display component F at 16 [ms], It is stored that the spindle speed display component S is updated at 128 [ms] and the modal display component M is updated at 128 [ms].

The determining unit 222 determines the behavior of the operator. Specifically, the determination unit 222 determines which screen component among the plurality of screen components the operator is paying attention to, based on the information regarding the operator's behavior acquired by the acquisition unit 9. For example, when the operator looks at one screen component continuously for three seconds or more, the determination unit 222 determines that the operator is paying attention to the screen component.

The determining unit 223 determines the update cycle of the screen component based on the relationship between the update cycle of the screen component stored in the storage unit 221 and the operator's behavior and the operator's behavior determined by the determining unit 222.

For example, when the determination unit 222 determines that the operator is paying attention to the coordinate value display component C, the determination unit 223 sets the update cycle of the coordinate value display component C to 16 [ms] and the feed rate display component F. The update cycle is determined to be 128 [ms], the update cycle of the spindle speed display component S is determined to be 128 [ms], and the update cycle of the modal display component M is determined to be 128 [ms].

Further, when the determination unit 222 determines that the operator is paying attention to the feed rate display component F, the determination unit 223 sets the update cycle of the coordinate value display component C to 128 [ms], and sets the update cycle of the coordinate value display component C to 128 [ms]. The update cycle is determined to be 16 [ms], the update cycle of the spindle speed display component S to 128 [ms], and the update cycle of the modal display component M to 128 [ms].

FIGS. 15A and 15B are diagrams showing examples of screen components displayed on the display screen. For example, before starting automatic operation, if the operator is not paying attention to any of the screen components, the display unit 224 displays coordinate value display component C, feed rate display component F, spindle speed display component S, and modal display component C. All display parts M are updated and displayed at the same update cycle of 64 [ms].

When the determining unit 222 determines that the operator is paying attention to the coordinate value display component C based on the information from the acquisition unit 9, the determining unit 223 sets the update cycle of the coordinate value display component C to 16 [ms]. , the update cycle of the feed speed display component F is determined to be 128 [ms], the update cycle of the spindle speed display component S is determined to be 128 [ms], and the update cycle of the modal display component M is determined to be 128 [ms].

The display unit 224 displays at least each screen component based on the update cycle determined by the determination unit 223 (see FIG. 15B).

As described above, the display device 22 includes a storage unit 221 that stores the relationship between the update cycle of at least one screen component displayed on the display screen and the operator's behavior, and a determination unit 222 that determines the operator's behavior. and a determining unit 223 that determines the update cycle based on the relationship stored in the storage unit 221 and the behavior of the operator determined by the determining unit, and at least It includes a display section 224 that displays one screen component.

Therefore, the display device 22 can change the update cycle of screen components without burdening the operator with operations to specify screen components. Further, it is possible to shorten only the update period of the screen parts that are noticed by the operator. As a result, it is possible to smoothly update the display of the screen component that attracts the operator's attention. Further, since the display device 22 shortens the update period of only the screen components that are noticed by the operator, it is not necessary to use the expensive and highly functional hardware processor 201. Therefore, the cost of the display device 22 can be reduced.

In the embodiment described above, the relationship between the update cycle of screen components and the operator's actions is stored in a table, and the determining unit 223 uses the table to determine the update cycle. However, the storage unit 221 may store, for example, priorities when displaying a plurality of screen components. For example, the storage unit 221 stores that the priorities of the coordinate value display component C, the feed rate display component F, the spindle speed display component S, and the modal display component M are 1, 2, 3, and 4, respectively. In this case, 1 has the highest priority and 4 has the lowest priority.

The determining unit 222 determines the behavior of the operator. That is, the determining unit 222 determines which screen component the operator is paying attention to.

The determining unit 223 determines the update cycle of the screen component that the operator is paying attention to to be shorter than the update cycle of other screen components. For example, when the determining unit 222 determines that the operator is paying attention to the feed rate display component F, the determining unit 223 determines the update cycle of the feed rate display component F to be 16 [ms]. Further, the determining unit 223 determines the update period of screen components other than the feed rate display component F based on the priority.

For example, the determining unit 223 determines the update cycle of the coordinate value display component C, which has the highest priority among the coordinate value display component C, the spindle speed display component S, and the modal display component M, to 64 [ms], for example. . Further, the determining unit 223 determines the update period of the spindle speed display component S having the next highest priority to, for example, 128 [ms]. Further, the determining unit 223 determines the update cycle of the modal display component M having the lowest priority to, for example, 256 [ms].

The display unit 224 displays a plurality of screen components based on the update cycle determined by the determination unit 223.

Furthermore, the storage unit 221 may store the relationship between the update cycle and the state of the industrial machine 1 or the relationship between the update cycle and the operator's behavior using a function.

For example, the storage unit 221 may store a function indicating the relationship between the feed rate of the control axis of the industrial machine 1 and the update period of the coordinate value display component C. In this case, the faster the feed speed of the control axis is, the shorter the update period of the coordinate value display component C may be.

As described above, the screen component is an image displayed on the display screen to present or receive various information regarding the industrial machine 1, and a program for displaying the image. Therefore, the determination unit 222, the determination unit 223, and the display unit 224 may be implemented as functions of screen components. In other words, the screen component itself may determine the update cycle by determining the state of the industrial machine 1 or the operator's actions. Alternatively, the functions of the determination unit 222 and the determination unit 223 may be implemented in addition to the screen component, and the display unit 224 may be implemented in the screen component.

Note that the present disclosure is not limited to the above embodiments, and can be modified as appropriate without departing from the spirit. For example, any component of the embodiment of the present disclosure may be modified or any component of the embodiment may be omitted. Specifically, the storage unit 221 may store the relationship between the update cycle of the screen components and the state of the industrial machine 1, and the relationship between the update cycle of the screen components and the operator's actions. In this case, the determination unit 222 may determine both the state of the industrial machine 1 and the operator's behavior. The determining unit 223 determines the update cycle based on the relationship stored in the storage unit 221 and the state of the industrial machine 1 determined by the determining unit 222, and determines the update cycle based on the relationship stored in the storage unit 221 and the state of the industrial machine 1 determined by the determining unit Both determining the update period based on the determined operator behavior may be performed.
