Description

The present disclosure relates to a display device and a computer-readable storage medium.

Multiple screen components are displayed on the display screen of a control device that controls industrial machinery. These screen components include, for example, a screen component that displays the feed rate and a screen component that displays the rotation speed of the spindle. These multiple screen components are configured to be updated at different update cycles.

In addition, a control device is known that allows an operator to specify a screen part and update the specified screen part at an update period shorter than the update period of other screen parts (for example, Patent Document 1).

Japanese Patent Application Publication No. 11-238027

However, with the technology described in Patent Document 1, in order to shorten the update cycle of a certain screen component, the operator must intentionally operate the cursor displayed on the display screen to specify the screen component. As a result, the operation of specifying the screen component is a burden for the operator.

Therefore, there is a demand for a display device that can change the update period of screen components without burdening the operator with the operation of specifying screen components.

The display device comprises: a memory unit that stores the relationship between the update period of at least one screen component displayed on the display screen and at least one of the state of the industrial machine and the action of the operator; a judgment unit that judges at least one of the state and the action; a decision unit that performs at least one of determining the update period based on the relationship stored in the memory unit and the state judged by the judgment unit and determining the update period based on the relationship stored in the memory unit and the action judged by the judgment unit; and a display unit that displays the at least one screen component based on the update period determined by the decision unit.

A computer-readable storage medium stores instructions that cause a computer to perform at least one of the following: storing the relationship between the update period of at least one screen component displayed on a display screen and at least one of the state of the industrial machine and the action of the operator; determining at least one of the state and the action; determining the update period based on the stored relationship and the determined state; and determining the update period based on the stored relationship and the determined action; and displaying the at least one screen component based on the determined update period.

One aspect of the present disclosure makes it possible to change the update period of screen components without burdening the operator with the operation of specifying screen components.

Display devices according to embodiments of the present disclosure will be described below with reference to the drawings. Note that not all combinations of features described in the following embodiments are necessarily required to solve the problem. In addition, more detailed explanation than necessary may be omitted. Furthermore, the following description of the embodiments and the drawings are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the scope of the claims.

A display device is a device that displays information about industrial machinery on a display screen. Industrial machinery includes, for example, machine tools, wire electric discharge machines, injection molding machines, industrial robots, and 3D printers. Machine tools include, for example, lathes, machining centers, and multi-tasking machines.

Information about industrial machinery includes, for example, information indicating the position, speed, and acceleration of multiple control axes of the industrial machinery. Information about industrial machinery includes information about operation programs that operate the industrial machinery. Operation programs are, for example, machining programs for machine tools and operation programs for industrial robots.

The display device is implemented, for example, in a control device that controls industrial machinery. The display device may also be implemented in a server connected to the control device or in a PC (Personal Computer). The following describes a display device implemented in a control device.

Figure 1 is a block diagram showing an example of the hardware configuration of an industrial machine equipped with a control device. The industrial machine 1 includes a control device 2, an input/output device 3, a servo amplifier 4, a servo motor 5, a spindle amplifier 6, a spindle motor 7, and auxiliary equipment 8.

The control device 2 is a device that controls the entire industrial machine 1. The control device 2 includes a hardware processor 201, a bus 202, a ROM (Read Only Memory) 203, a RAM (Random Access Memory) 204, and a non-volatile memory 205.

The hardware processor 201 is a processor that controls the entire control device 2 in accordance with a system program. The hardware processor 201 reads the system program stored in the ROM 203 via the bus 202 and performs various processes based on the system program. The hardware processor 201 controls the servo motor 5 and the spindle motor 7, for example, based on a machining program. The hardware processor 201 is, for example, a CPU (Central Processing Unit) or an electronic circuit.

The hardware processor 201, for example, analyzes the machining program and outputs control commands to the servo motor 5 and the spindle motor 7 for each control period.

Bus 202 is a communication path that connects each piece of hardware within control device 2 to each other. Each piece of hardware within control device 2 exchanges data via bus 202.

ROM 203 is a storage device that stores system programs and the like for controlling the entire control device 2. ROM 203 is a computer-readable storage medium.

RAM 204 is a storage device that temporarily stores various data. RAM 204 functions as a working area for the hardware processor 201 to process various data.

The non-volatile memory 205 is a storage device that retains data even when the industrial machine 1 is turned off and no power is supplied to the control device 2. The non-volatile memory 205 stores, for example, operating programs and various parameters. The non-volatile memory 205 is a computer-readable storage medium. The non-volatile memory 205 is, for example, a battery-backed memory or an SSD (Solid State Drive).

The control device 2 further includes an interface 206, an axis control circuit 207, a spindle control circuit 208, a PLC (Programmable Logic Controller) 209, and an I/O unit 210.

The interface 206 connects the bus 202 to the input/output device 3. The interface 206 sends, for example, various data processed by the hardware processor 201 to the input/output device 3.

The input/output device 3 receives various data via the interface 206 and displays the various data. The input/output device 3 also accepts input of various data and sends the various data via the interface 206 to, for example, the hardware processor 201.

The input/output device 3 is, for example, a touch panel. The input/output device 3 is, for example, a capacitive touch panel. Note that the touch panel is not limited to a capacitive touch panel and may be a touch panel of another type. The input/output device 3 is installed on an operation panel (not shown) in which the control device 2 is housed.

The axis control circuit 207 is a circuit that controls the servo motor 5. The axis control circuit 207 receives control commands from the hardware processor 201 and sends various commands to the servo amplifier 4 to drive the servo motor 5. The axis control circuit 207 sends, for example, torque commands to the servo amplifier 4 to control the torque of the servo motor 5.

The servo amplifier 4 receives commands from the axis control circuit 207 and supplies current to the servo motor 5.

Servomotor 5 is driven by receiving a current supply from servo amplifier 4. Servo motor 5 is provided on each control axis of industrial machine 1. If industrial machine 1 is a machine tool having five axes, servo motor 5 includes, for example, an X-axis servo motor, a Y-axis servo motor, a Z-axis servo motor, an A-axis servo motor, and a C-axis servo motor.

The servo motor 5 is connected to, for example, a ball screw that drives the tool post. When the servo motor 5 is driven, a structure of the industrial machine 1, such as the tool post, moves in a predetermined control axis direction. The servo motor 5 has a built-in encoder (not shown) that detects the position and feed rate of the control axis. Position feedback information and speed feedback information indicating the position and feed rate of the control axis detected by the encoder, respectively, are fed back to the axis control circuit 207. As a result, the axis control circuit 207 performs feedback control of the control axis.

The spindle control circuit 208 is a circuit for controlling the spindle motor 7. The spindle control circuit 208 receives control commands from the hardware processor 201 and sends commands to the spindle amplifier 6 to drive the spindle motor 7. The spindle control circuit 208 sends, for example, a spindle speed command to the spindle amplifier 6 to control the rotational speed of the spindle motor 7.

The spindle amplifier 6 receives instructions from the spindle control circuit 208 and supplies current to the spindle motor 7.

The spindle motor 7 is driven by a current supplied from the spindle amplifier 6. The spindle motor 7 is connected to the main shaft and rotates the main shaft.

The PLC 209 is a device that executes a ladder program to control the auxiliary equipment 8. The PLC 209 sends commands to the auxiliary equipment 8 via the I/O unit 210.

The I/O unit 210 is an interface that connects the PLC 209 and the auxiliary device 8. The I/O unit 210 sends commands received from the PLC 209 to the auxiliary device 8.

The auxiliary equipment 8 is installed in the industrial machine 1 and performs auxiliary operations in the industrial machine 1. The auxiliary equipment 8 operates based on commands received from the I/O unit 210. The auxiliary equipment 8 may also be equipment installed in the periphery of the industrial machine 1. The auxiliary equipment 8 is, for example, a tool changer, a cutting fluid injection device, or an opening/closing door drive device.

Figure 2 is a block diagram showing an example of the functions of the control device 2 that controls the industrial machine 1. The control device 2 includes a control unit 21 and a display device 22. The control unit 21 is realized, for example, by the hardware processor 201 performing arithmetic processing using a system program stored in ROM 203, an operating program stored in non-volatile memory 205, and various data.

The control unit 21 controls one or more control axes of the industrial machine 1 based on an operating program. The one or more control axes include, for example, at least one of the X-axis, Y-axis, and Z-axis. The multiple control axes may further include at least one of the A-axis, B-axis, and C-axis.

The control unit 21 outputs information indicating the state of the industrial machinery 1 to the display device 22. The state of the industrial machinery 1 means the setting state and operating state of the industrial machinery 1.

The set state includes an operation mode set state in which one of multiple operation modes is set. The operation state includes an edit state in which an operation program is being edited, an execution state in which an operation program is being executed, and an interrupt state in which an interrupt is being executed. The operation state may also include the position, speed, and acceleration of multiple control axes.

The information indicating the state of the industrial machinery 1 includes at least one of an operation mode signal, an automatic operation start signal, and an interrupt signal.

The operation mode signal is a signal that indicates the operation mode set for the industrial machine 1. The operation modes include an automatic operation mode, an MDI (Manual Data Input) operation mode, and a manual operation mode. The operation mode signal includes an automatic operation mode signal, an MDI operation mode signal, and a manual operation mode signal, which correspond to these operation modes, respectively.

The automatic operation mode is a mode in which the industrial machine 1 operates automatically based on a pre-created operating program. The automatic operation mode is used, for example, when the industrial machine 1 processes multiple workpieces continuously.

The MDI operation mode is a mode in which the industrial machine 1 operates based on an operating program manually input by the operator. The MDI operation mode is used, for example, when a simple operation test of the industrial machine 1 is performed.

The manual operation mode is a mode in which an operator operates the industrial machine 1 using the axis movement switch on the control panel and a pulse generator, etc. The manual operation mode is used, for example, when preparing the industrial machine 1 for operation.

The automatic operation start signal is a signal indicating that automatic operation has started and the operating program is running. The automatic operation start signal is a signal indicating that the operation program has started running when the cycle start button is pressed.

An interrupt signal is a signal that indicates that an interrupt has occurred during automatic operation of the industrial machine 1 and that the interrupt is currently being executed. The interrupt signal is output, for example, when an operator performs an interrupt operation when the execution of the operating program is temporarily suspended. The interrupt operation is performed, for example, by turning on a specified switch on the control panel of the control device 2. Note that while an interrupt is being executed, the operator can operate the industrial machine 1 using the axis movement switch on the control panel and a pulse generator, etc., just as in manual operation mode.

The display device 22 includes a memory unit 221, a judgment unit 222, a decision unit 223, and a display unit 224. The memory unit 221 is realized, for example, by storing various data and programs in RAM 204 or non-volatile memory 205. The judgment unit 222, decision unit 223, and display unit 224 are realized, for example, by the hardware processor 201 performing calculations using the system program stored in ROM 203, the operating program stored in non-volatile memory 205, and various data.

The memory unit 221 stores the relationship between the update period of at least one screen component displayed on the display screen and the state of the industrial machinery 1.

The display screen is, for example, the display screen of the input/output device 3. Screen components are images displayed on the display screen to present or accept various information related to the industrial machinery 1, and programs for displaying those images.

Screen components include, for example, a coordinate value display component that displays coordinate values indicating the position of the control axis, an editor component used to edit the operation program, a feed rate display component that displays the feed rate of the control axis, a spindle speed display component that displays the rotational speed of the spindle, and a modal display component that displays modal commands that are in effect during execution of the operation program.

The update cycle is the cycle at which the information displayed by the screen component is updated. In other words, the screen component displays new, updated information at each update cycle. The update cycle can be, for example, 16 ms, 64 ms, 128 ms, or 256 ms.

As described above, the state of the industrial machine 1 refers to the operating state or setting state of the industrial machine 1. The operating state includes an editing state in which an operation program is being edited, an interrupt state in which an interrupt is being executed, and an execution state in which an operation program is being executed. The setting state includes an operating mode setting state in which one of multiple operating modes is set. For example, if the automatic operation mode is set, the state of the industrial machine 1 becomes the automatic operation mode setting state. The memory unit 221 stores the relationship between the update period and the state of the industrial machine 1, for example, using a table.

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

The memory unit 221 stores information that, in the editing state, the coordinate value display component is updated every 128 ms and the editor component is updated every 16 ms. Also, in the execution state, the memory unit 221 stores information that, in the editing state, the coordinate value display component is updated every 16 ms and the editor component is updated every 128 ms.

When editing an operating program, the operator pays more attention to the editor component than to the coordinate value display component. Also, during automatic operation, the operator pays more attention to the coordinate value display component than to the editor component. Therefore, in the editing state, the update cycle of the editor component is set to be short, and in the execution state, the update cycle of the coordinate value display component is set to be short. Now, let's return to the explanation of Figure 2.

The judgment unit 222 receives information indicating the state of the industrial machine 1 from the control unit 21 and judges the state of the industrial machine 1. The information indicating the state of the industrial machine 1 is a signal output by the control device 2. For example, if the industrial machine 1 is set to MDI operation mode, the control unit 21 outputs an MDI operation mode signal to the judgment unit 222. Upon receiving the MDI operation mode signal, the judgment unit 222 judges that the industrial machine 1 is set to MDI operation mode. In other words, the judgment unit 222 judges that the state of the industrial machine 1 is set to MDI operation mode.

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

The control unit 21 may send an editing signal indicating that the industrial machine 1 is in an editing state to the judgment unit 222 when the industrial machine 1 is set to the MDI operation mode and the editor component is ready to accept command input from the operator. In response to receiving the editing signal, the judgment unit 222 may determine that the industrial machine 1 is in an editing state.

The determination unit 223 determines the update period of the screen components based on the relationship between the update period of the screen components stored in the memory unit 221 and the state of the industrial machinery 1, and the state of the industrial machinery 1 determined by the determination unit 222.

For example, when the judgment unit 222 determines that the state of the industrial machine 1 is in the MDI operation mode setting state and in the editing state, the determination unit 223 determines the update period of the coordinate value display component to be 128 [ms] and the update period of the editor component to be 16 [ms].

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

Figure 4 is a diagram showing an example of a screen component displayed on the display screen. If the determination unit 223 determines the update period 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. If the determination unit 223 determines the update period of the editor component E to be 16 ms, the display unit 224 updates and displays the editor component E every 16 ms. The display unit 224 may also display an image indicating the update period on the display screen, as shown in Figure 4. The update period of the other screen components shown in Figure 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 editor component E is completed and execution of the input operation program begins, the control unit 21 outputs an automatic operation start signal to the judgment unit 222. When the judgment unit 222 receives the automatic operation start signal, the judgment unit 222 judges that the industrial machine 1 is in automatic operation, i.e., the state of the industrial machine 1 is in the execution state.

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

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

Figure 5 is a diagram showing an example of a screen component displayed on the display screen. If the determination unit 223 determines that the update period of the coordinate value display component C is 16 ms, the display unit 224 updates and displays the coordinate value display component C at an update period of every 16 ms. If the determination unit 223 determines that the update period of the editor component E is 128 ms, the display unit 224 updates and displays the editor component E at an update period of every 128 ms. The display unit 224 may also display an image indicating the update period on the display screen, as shown in Figure 5.

Figure 6 is a diagram showing an example of the relationship between the update cycle of screen components stored in the memory unit 221 and the state of the industrial machine 1. Figure 6 is a diagram showing the relationship between the update cycle of screen components in the automatic operation mode and the manual operation mode and the state of the industrial machine 1. The screen components include a coordinate value display component C, a feed rate display component, a spindle speed display component, and a modal display component.

The memory unit 221 stores the following information: when in automatic operation mode, the coordinate value display component C is updated every 64 ms, the feed rate display component is updated every 16 ms, the spindle speed display component is updated every 16 ms, and the modal display component is updated every 128 ms. Furthermore, when in manual operation mode, the memory unit 221 stores the following information: when in manual operation mode, the coordinate value display component C is updated every 16 ms, the feed rate display component is updated every 128 ms, the spindle speed display component is updated every 128 ms, and the modal display component is updated every 128 ms.

In automatic operation mode, the operator pays most attention to the feed rate display component and spindle speed display component, followed by the coordinate value display component C, and pays less attention to the modal display component. In manual operation mode, the operator pays attention to the coordinate value display component C, and pays less attention to the feed rate display component, spindle speed display component, and 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 Figure 6.

When the industrial machine 1 is set to the automatic operation mode, the control unit 21 outputs an automatic operation mode signal to the judgment unit 222. When the judgment unit 222 receives the automatic operation mode signal, it judges that the industrial machine 1 is set to the automatic operation mode. In other words, the judgment unit 222 judges that the state of the industrial machine 1 is in the automatic operation mode setting state.

Furthermore, when the industrial machine 1 is set to manual operation mode, the control unit 21 outputs a manual operation mode signal to the judgment unit 222. Upon receiving the manual operation mode signal, the judgment unit 222 judges that the industrial machine 1 is set to manual operation mode. In other words, the judgment unit 222 judges that the state of the industrial machine 1 is in the manual operation mode setting state.

When the judgment unit 222 determines that the state of the industrial machine 1 is in the automatic operation mode setting state, the determination unit 223 determines the update period of the coordinate value display component C to be 64 [ms], the update period of the feed speed display component to be 16 [ms], the update period of the spindle speed display component to be 16 [ms], and the update period of the modal display component to be 128 [ms].

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

Figure 7 is a diagram showing an example of screen components displayed on the display screen. If the determination unit 223 determines the update period of the coordinate value display component C to be 64 ms, the display unit 224 updates and displays the coordinate value display component C at an update period of every 64 ms. If the determination unit 223 determines the update period of the feed rate display component F to be 16 ms, the display unit 224 updates and displays the feed rate display component F at an update period of every 16 ms. If the determination unit 223 determines the update period of the spindle speed display component S to be 16 ms, the display unit 224 updates and displays the spindle speed display component S at an update period of every 16 ms. If the determination unit 223 determines the update period of the modal display component M to be 128 ms, the display unit 224 updates and displays the modal display component M at an update period of every 128 ms. Note that the display unit 224 may display an image indicating the update period on the display screen, as shown in Figure 7.

When the judgment unit 222 determines that the state of the industrial machine 1 is in the manual operation mode setting state, the determination unit 223 determines the update period of the coordinate value display component C to 16 [ms], the update period of the feed speed display component F to 128 [ms], the update period of the spindle speed display component S to 128 [ms], and the update period of the modal display component M to 128 [ms].

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

Figure 8 is a diagram showing an example of screen components displayed on the display screen. If the determination unit 223 determines the update period of the coordinate value display component C to be 16 ms, the display unit 224 updates the update period of the coordinate value display component C every 16 ms and displays it. If the determination unit 223 determines the update period of the feed rate display component F to be 128 ms, the display unit 224 updates the update period of the feed rate display component F every 128 ms and displays it. If the determination unit 223 determines the update period of the spindle speed display component S to be 128 ms, the display unit 224 updates the update period of the spindle speed display component S every 128 ms and displays it. If the determination unit 223 determines the update period of the modal display component M to be 128 ms, the display unit 224 updates the update period of the modal display component M every 128 ms and displays it. The display unit 224 may display an image indicating the update period on the display screen, as shown in FIG.

Figure 9 is a diagram showing an example of the relationship between the update cycle of screen components stored in the memory unit 221 and the state of the industrial machine 1. Figure 9 is a diagram showing the relationship between the update cycle of screen components in an automatic operation mode in an uninterrupted state and the state of the industrial machine 1, and the relationship between the update cycle of screen components in an automatic operation mode in an interrupted state in which an interrupt has occurred and the state of the industrial machine 1. The screen components include a coordinate value display component C, a feed rate display component F, a spindle speed display component S, and a modal display component M.

The memory unit 221 stores the following information: when the automatic operation mode is set and no interrupt has occurred, the coordinate value display component C is updated every 64 ms, the feed rate display component F is updated every 16 ms, the spindle speed display component S is updated every 16 ms, and the modal display component M is updated every 128 ms. The memory unit 221 also stores the following information: when the automatic operation mode is set and an interrupt has occurred, the coordinate value display component C is updated every 16 ms, the feed rate display component F is updated every 16 ms, the spindle speed display component S is updated every 16 ms, and the modal display component M is updated every 256 ms.

In automatic operation mode when no interrupts have occurred, the operator will pay most attention to the feed rate display component F and the spindle speed display component S, followed by the coordinate value display component C, and will not pay much attention to the modal display component M. Also, when an interrupt occurs in automatic operation mode and manual operation is performed using a pulse generator or the like, the operator will pay attention to the coordinate value display component C, the feed rate display component F, and the spindle speed display component S, and will not pay much attention to the modal display component M. Therefore, the update cycles for each screen component when no interrupts have occurred in automatic operation mode and when an interrupt has occurred in automatic operation mode are set as shown in Figure 9.

When the industrial machine 1 is set to the automatic operation mode, the control unit 21 outputs an automatic operation mode signal to the judgment unit 222. When the judgment unit 222 receives the automatic operation mode signal, it judges that the state of the industrial machine 1 is set to the automatic operation mode.

When the judgment unit 222 determines that the state of the industrial machine 1 is in automatic operation mode and that no interrupt has occurred, the determination unit 223 determines the update period of the coordinate value display component C to be 64 [ms], the update period of the feed speed display component F to be 16 [ms], the update period of the spindle speed display component S to be 16 [ms], and the update period of the modal display component M to be 128 [ms].

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

Figure 10 is a diagram showing an example of screen components displayed on the display screen. If the determination unit 223 determines the update period of the coordinate value display component C to be 64 ms, the display unit 224 updates the update period of the coordinate value display component C every 64 ms and displays it. If the determination unit 223 determines the update period of the feed rate display component F to be 16 ms, the display unit 224 updates the update period of the feed rate display component F every 16 ms and displays it. If the determination unit 223 determines the update period of the spindle speed display component S to be 16 ms, the display unit 224 updates the update period of the spindle speed display component S every 16 ms and displays it. If the determination unit 223 determines the update period of the modal display component M to be 128 ms, the display unit 224 updates the update period of the modal display component M every 128 ms and displays it. The display unit 224 may display an image indicating the update period on the display screen, as shown in FIG.

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

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

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

Figure 11 is a diagram showing an example of screen components displayed on the display screen. If the determination unit 223 determines the update period of the coordinate value display component C to be 16 ms, the display unit 224 updates the update period of the coordinate value display component C every 16 ms and displays it. If the determination unit 223 determines the update period of the feed rate display component F to be 16 ms, the display unit 224 updates the update period of the feed rate display component F every 16 ms and displays it. If the determination unit 223 determines the update period of the spindle speed display component S to be 16 ms, the display unit 224 updates the update period of the spindle speed display component S every 16 ms and displays it. If the determination unit 223 determines the update period of the modal display component M to be 256 ms, the display unit 224 updates the update period of the modal display component M every 256 ms and displays it. The display unit 224 may display an image indicating the update period on the display screen, as shown in FIG.

Figure 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 judgment unit 222 receives information indicating the state of the industrial machine 1 (step S1).

Next, the judgment unit 222 judges the state of the industrial machinery 1 based on the received information indicating the state of the industrial machinery 1 (step S2).

Next, the determination unit 223 determines the update period of the screen components based on the relationship between the update period stored in the memory unit 221 and the state of the industrial machinery 1, and the state of the industrial machinery 1 determined by the determination unit 222 (step S3).

Next, the display unit 224 displays the screen components based on the update cycle determined by the determination unit 223 (step S4), and then ends the processing. The display unit 224 receives information indicating the status of the industrial machine 1, such as information indicating the position of the control axis, from the control unit 21 and displays it on each screen component.

As described above, the display device 22 comprises a memory unit 221 that stores the relationship between the update period of at least one screen component displayed on the display screen and the state of the industrial machinery 1, a judgment unit 222 that judges the state of the industrial machinery 1, a determination unit 223 that determines the update period based on the relationship stored in the memory unit 221 and the state of the industrial machinery 1 judged by the judgment unit 222, and a display unit 224 that displays at least one screen component based on the update period determined by the determination unit 223.

The display device 22 is therefore able to change the update period of screen parts without burdening the operator with the operation of specifying screen parts. Furthermore, it is possible to shorten only the update period of screen parts that are of interest to the operator, 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. Furthermore, it is possible to smoothly update the display of screen parts that the operator is interested in.

In addition, the display device 22 shortens the update cycle only for screen components that are of interest to the operator, allowing for smooth updates of the display of screen components without the need for an expensive, highly functional hardware processor 201. This allows for cost reductions for the display device 22.

The judgment unit 222 also judges the state of the industrial machine 1 based on signals output by the control device 2 that controls the industrial machine 1. The signals output by the control device 2 include an operation mode signal that indicates the operation mode of the industrial machine 1. The signals output by the control device 2 also include an automatic operation start signal that indicates that automatic operation of the industrial machine 1 has started. The signals output by the control device 2 also include an interrupt signal that indicates that an interrupt has occurred. Therefore, the display device 22 can change the update period of each screen component according to various states of the industrial machine 1.

In addition, the memory unit 221 stores the relationship between the update period and the state of the industrial machinery 1 using a table. Therefore, the operator can easily understand, for example, the relationship between the update period and the state of the industrial machinery 1.

In addition, 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 above-described embodiment, the memory unit 221 stores the relationship between the update period of the screen components and the state of the industrial machinery 1. The judgment unit 222 judges the state of the industrial machinery 1. The determination unit 223 determines the update period based on the relationship stored in the memory unit 221 and the state of the industrial machinery 1 judged by the judgment unit 222.

However, the memory 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 behavior. In this case, the judgment unit 222 judges the operator's behavior based on information from an acquisition unit that monitors the operator's behavior and acquires information about the operator's behavior. The determination unit 223 determines the update cycle of each screen component based on the relationship stored in the memory unit 221 and the operator's behavior determined by the determination unit 222.

Figure 13 is a block diagram showing an example of the functions of a display device 22 in which the update period for screen components is determined based on the operator's actions. The block diagram shown in Figure 13 differs from the control device 2 shown in Figure 2 in that the acquisition unit 9 is connected to the display device 22. Therefore, here we will explain the acquisition unit 9 and its related functions, and will omit explanations of functions that are the same as those explained using Figure 2.

The acquisition unit 9 monitors the operator's behavior and acquires information about the operator's behavior. The operator's behavior may be, for example, which of multiple screen components the operator is focusing on. In other words, 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 judgment unit 222. The information regarding the operator's behavior is, for example, gaze information indicating the operator's line of sight.

The memory unit 221 stores the update period of at least one screen component displayed on the display screen and its relationship with the operator's actions.

Figure 14 is a diagram showing an example of the relationship between the update cycles of screen parts stored in the memory unit 221 and the actions of the operator. The memory unit 221 stores in a table the update cycles of the screen parts that the operator is focusing on and the update cycles of screen parts other than the screen parts that the operator is focusing on. In other words, the memory unit 221 stores the update cycles of the screen parts that are in the operator's line of sight and the update cycles of the other screen parts.

The memory unit 221 stores the following information: when the operator is looking at the coordinate value display component C, the coordinate value display component C is updated every 16 [ms], the feed speed display component F is updated every 128 [ms], the spindle speed display component S is updated every 128 [ms], and the modal display component M is updated every 128 [ms].

In addition, the memory unit 221 stores the following information: when the operator is looking at the feed speed display component F, the coordinate value display component C is updated every 128 [ms], the feed speed display component F is updated every 16 [ms], the spindle speed display component S is updated every 128 [ms], and the modal display component M is updated every 128 [ms].

The determination unit 222 determines the operator's behavior. Specifically, the determination unit 222 determines which of multiple screen components the operator is focusing on, based on information about the operator's behavior acquired by the acquisition unit 9. For example, if the operator directs their gaze at one screen component for three or more consecutive seconds, the determination unit 222 determines that the operator is focusing on that screen component.

The determination unit 223 determines the update period of the screen components based on the relationship between the update period of the screen components stored in the memory unit 221 and the operator's behavior and the operator's behavior determined by the determination unit 222.

For example, when the judgment unit 222 determines that the operator is looking at the coordinate value display component C, the determination unit 223 determines the update period of the coordinate value display component C to be 16 [ms], the update period of the feed speed display component F to be 128 [ms], the update period of the spindle speed display component S to be 128 [ms], and the update period of the modal display component M to be 128 [ms].

Furthermore, when the judgment unit 222 determines that the operator is looking at the feed speed display component F, the determination unit 223 determines the update period of the coordinate value display component C to 128 [ms], the update period of the feed speed display component F to 16 [ms], the update period of the spindle speed display component S to 128 [ms], and the update period of the modal display component M to 128 [ms].

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

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

If the judgment unit 222 determines based on information from the acquisition unit 9 that the operator is looking at the coordinate value display component C, the determination unit 223 determines the update period of the coordinate value display component C to be 16 [ms], the update period of the feed speed display component F to be 128 [ms], the update period of the spindle speed display component S to be 128 [ms], and the update period of the modal display component M to be 128 [ms].

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

As described above, the display device 22 comprises a memory unit 221 that stores the relationship between the update period of at least one screen component displayed on the display screen and the operator's behavior, a judgment unit 222 that judges the operator's behavior, a determination unit 223 that determines the update period based on the relationship stored in the memory unit 221 and the operator's behavior judged by the judgment unit, and a display unit 224 that displays at least one screen component based on the update period determined by the determination unit 223.

The display device 22 is therefore able to change the update cycle of screen parts without placing the burden of specifying screen parts on the operator. It is also possible to shorten the update cycle of only the screen parts that are the focus of the operator. As a result, the display of the screen parts that the operator is focusing on can be updated smoothly. Furthermore, because the display device 22 shortens the update cycle of only the screen parts that are the focus of the operator, it is not necessary to use an expensive, highly functional hardware processor 201. This allows for a reduction in the cost of the display device 22.

In the above-described embodiment, the relationship between the update cycle of screen components and the actions of the operator is stored in a table, and the determination unit 223 determines the update cycle using the table. However, the memory unit 221 may, for example, store the priorities for displaying multiple screen components. For example, the memory unit 221 stores that the priorities of the coordinate value display component C, feed rate display component F, spindle speed display component S, and modal display component M are 1, 2, 3, and 4, respectively. In this case, 1 is the highest priority and 4 is the lowest priority.

The judgment unit 222 judges the operator's actions. In other words, the judgment unit 222 determines the screen part that the operator is focusing on.

The determination unit 223 determines the update period of the screen component that the operator is focusing on to be shorter than the update periods of other screen components. For example, if the judgment unit 222 determines that the operator is focusing on the feed speed display component F, the determination unit 223 determines the update period of the feed speed display component F to be 16 ms. The determination unit 223 also determines the update periods of screen components other than the feed speed display component F based on priority.

For example, the determination unit 223 determines the update period 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 be, for example, 64 ms. The determination unit 223 also determines the update period of the spindle speed display component S, which has the next highest priority, to be, for example, 128 ms. The determination unit 223 also determines the update period of the modal display component M, which has the lowest priority, to be, for example, 256 ms.

The display unit 224 displays multiple screen components based on the update period determined by the determination unit 223.

In addition, the memory unit 221 may store the relationship between the update period and the state of the industrial machinery 1, or the relationship between the update period and the operator's actions, using a function.

For example, the memory unit 221 may store a function that indicates the relationship between the feed speed 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, the shorter the update period of the coordinate value display component C should be.

As described above, screen components are images displayed on the display screen to present or accept various types of information related to the industrial machine 1, and programs for displaying those images. Therefore, the judgment unit 222, decision unit 223, and display unit 224 may be implemented as functions of the screen components. In other words, the screen components themselves may judge the state of the industrial machine 1 or the actions of the operator and determine the update period. Alternatively, the functions of the judgment unit 222 and decision unit 223 may be implemented outside the screen components, and the display unit 224 may be implemented in the screen components.

Note that the present disclosure is not limited to the above-described embodiments and may be modified as appropriate without departing from the spirit of the present disclosure. For example, any of the components of the embodiments of the present disclosure may be modified or omitted. Specifically, the memory unit 221 may store the relationship between the update period of the screen components and the state of the industrial machine 1, and the relationship between the update period of the screen components and the behavior of the operator. In this case, the judgment unit 222 may judge both the state of the industrial machine 1 and the behavior of the operator. The determination unit 223 may perform both: determining the update period based on the relationship stored in the memory unit 221 and the state of the industrial machine 1 determined by the judgment unit 222; and determining the update period based on the relationship stored in the memory unit 221 and the behavior of the operator determined by the judgment unit 222.
