Description

  The present invention relates to a display control apparatus and a display control method for controlling display items of data displayed on a display.

For example, a digital controller (display control device) for controlling a control target such as a semiconductor manufacturing apparatus or an injection molding machine is generally mounted on a control panel to be controlled.
Many digital controllers include a digital display (for example, a 7-segment LED, a liquid crystal display) and operation keys (for example, up / down / left / right arrow keys).
The display items displayed on the digital display differ depending on the control target, but there are usually many items. When the operator selects an arbitrary display item, the data corresponding to that display item (measured value or set value) Is displayed on the digital display.

In general, a plurality of display items are hierarchized, and the order of display items to be switched by operation of an operation key is determined in a hierarchical structure. When a certain display item is selected from among a plurality of display items and data corresponding to the display item is displayed on the digital display, the operator desires to switch the display item to be displayed. It is necessary to switch display items to be displayed by operating the operation keys of the controller.
Therefore, if the operator is familiar with the hierarchical structure of a plurality of display items, the relationship between the currently displayed display item and the desired display item (display item for which a new display is desired) (positional relationship in the hierarchical structure) Therefore, a desired display item can be selected in a short time with a small number of key operations.
On the other hand, if the operator is not familiar with the hierarchical structure of a plurality of display items, it is necessary to check the currently selected display item every time a key operation is performed, and the operator's operation approaches the desired display item. The operation is not limited to the desired display item, but rather may be an operation away from the desired display item. Therefore, it takes a lot of key operations and time to complete the selection of the desired display item.

In addition, the digital controller has a key operation for a certain time (hereinafter referred to as “no-operation time”) from the last key operation even during the key operation for selecting a desired display item. If not, a display reset function for switching the display content of the digital display to data corresponding to a preset display item to be initially displayed is installed.
This no-operation time is set in advance, but if the operator is not familiar with the operation method, if the no-operation time is short, the display item returns to the initial display target until the desired operation is completed. Therefore, it is preferable that this non-operation time is long.
On the other hand, when the operator is familiar with the operation method, the desired operation can be completed in a short time. Therefore, the shorter the non-operation time, the better the operability.

  Patent Document 1 below does not update the no-operation time set in the digital controller. However, when registering the sale of a product, the skill level of the operator's key operation is determined, A skill level response device that displays a help screen if the skill level is low is disclosed.

JP 11-353076 A (for example, paragraphs [0016] to [0017])

  Since the conventional display control apparatus is configured as described above, an operator who is familiar with the hierarchical structure and operation method of a plurality of display items and an operator who is not familiar with the hierarchical structure and operation method of a plurality of display items If the no-operation time is set to a long time in accordance with an operator who is not familiar, the operability when the operator who is familiar with it operates is lowered. On the other hand, if the no-operation time is set to a short time according to the operator who is familiar, when an operator who is not familiar with the operation is operating, the operator returns to the initial display target display item before selecting the desired display item. There has been a problem that the performance may be significantly reduced.

  The present invention has been made to solve the above problems, and an object of the present invention is to provide a display control device and a display control method capable of realizing high operability regardless of which operator operates.

  The display control device according to the present invention corresponds to a hierarchical structure storage means for storing a hierarchical structure of a plurality of display items for a display, and a display item to be initially displayed among a plurality of display items. Initial display means for displaying data to be displayed on the display, switching operation accepting means for accepting a switching operation of display items by the operator, switching operation accepted by the switching operation accepting means, and a hierarchical structure stored by the hierarchical structure storage means The display items to be displayed are updated in accordance with the display switching means for switching the display contents of the display to the data corresponding to the display items to be updated, and the display contents are changed by the display switching means. When a new switching operation is not accepted by the switching operation accepting means until the preset no-operation time is reached, Display reset means for returning the display contents to data corresponding to the display items to be initially displayed, and skill level evaluation means for evaluating the skill level of the display item switching operation by the operator are provided. The no-operation time is updated according to the evaluation result of the skill level by the evaluation means.

  The display control apparatus according to the present invention updates the display item history indicating the display item to be displayed updated by the display switching unit every time the skill level evaluation unit receives a switching operation by the switching operation receiving unit, The skill level of the display item switching operation by the operator may be evaluated based on the display item history.

  In the display control device according to the present invention, the skill level evaluation unit determines whether the switching operation received by the switching operation receiving unit corresponds to a deduction target operation based on the update order of the display items indicated by the display item history. If the switching operation corresponds to the operation to be deducted, a process for lowering the skill level evaluation of the display item switching operation by the operator is performed, and the no-operation time updating means When the evaluation is lowered, it may be updated so that the no-operation time becomes longer.

  In the display control device according to the present invention, the skill level evaluation unit determines whether the switching operation received by the switching operation receiving unit corresponds to the operation to be added based on the update order of the display items indicated by the display item history. If the switching operation corresponds to the operation to be added, a process for increasing the skill level evaluation of the display item switching operation by the operator is performed, and the no-operation time updating means When evaluation is raised, you may update so that a non-operation time may become short.

  The display control device according to the present invention accepts a long-press operation that accepts a long-press operation of a key that instructs execution of a predetermined process when a key press time by an operator is longer than a preset long-press time. If the skill level evaluated by the means and the skill level evaluation means is increased, the long press time is updated so that the long press time is shortened. If the skill level is decreased, the long press time is updated so that the long press time is increased. Update means may be provided.

  The display control device according to the present invention is a key press operation by an operator as an operation for continuously increasing the value of data corresponding to a display item displayed on the display or an operation for continuously decreasing the value of the data. The process of increasing the value of the data at a preset change cycle or the data at the change cycle during a period when the long press operation accepted by the continuous change operation accepting unit is received. If the skill level evaluated by the data value changing means and the skill level evaluation means increases, the update period is updated so that the change period becomes shorter, and if the skill level decreases, the change period becomes You may make it provide the change period update means to update so that it may become long.

  In the display control device according to the present invention, if the switching operation reception means has a skill level evaluated by the skill level evaluation means higher than a preset threshold value, the display device has a hierarchical structure different from the plurality of display items. A display item change operation for displaying a plurality of display items may be accepted.

  The display control device according to the present invention receives data changing operation corresponding to the display item displayed on the display only when the skill level evaluated by the skill level evaluation means is higher than a preset threshold value. You may make it provide a change operation reception means.

  In the display control device according to the present invention, when the switching operation accepting unit is less than or equal to a preset threshold value when the skill level evaluated by the skill level evaluating unit is equal to or less than a preset threshold value, the display control device is configured to stop accepting display item switching operations by the operator. Anyway.

  The display control apparatus according to the present invention is configured so that the skill level evaluation unit returns the evaluation result of the skill level to the initial value when the switching operation is not received by the switching operation reception unit continuously for a preset time. Also good.

  The display control method according to the present invention includes an initial display processing step in which the initial display means displays data corresponding to a display item to be initially set among a plurality of display items for the display on the display. The switching operation accepting means accepts the switching operation of the display item by the operator, the switching operation accepting processing step, and the display switching means displays according to the switching operation accepted in the switching operation accepting processing step and the hierarchical structure of the plurality of display items. The display switching processing step for updating the display item of the target and switching the display content of the display to the data corresponding to the display item of the display target after the update, and the display reset means, the display content of the display is changed in the display switching processing step. A new switching operation is performed at the switching operation reception processing step after the switching until the preset no-operation time is reached. If not accepted, the display reset processing step for returning the display content of the display to the data corresponding to the display item to be initially displayed, and the skill level for the skill level evaluation means to evaluate the skill level of the switching operation of the display item by the operator The evaluation processing step and the no-operation time update means comprise a no-operation time update processing step for updating the no-operation time according to the skill level evaluation result in the skill level evaluation processing step.

  According to the present invention, since the no-operation time is updated according to the operation of the operator, there is an effect that high operability can be realized regardless of which operator operates.

Embodiment 1 FIG.
1 is a block diagram showing a display control apparatus according to Embodiment 1 of the present invention.
FIG. 2 is an explanatory diagram showing an example of the configuration of the display. In particular, FIG. 2A shows an item name display for displaying a display item being selected, and item-specific data (measurement values) corresponding to the display item. Alternatively, an example in which a display for data that displays a set value) is mounted is shown. FIG. 2B shows an example in which one display unit serves as both an item name display unit and a data display unit.
FIG. 3 is an explanatory diagram showing a plurality of display items arranged in a hierarchy. For example, PV, SV, d, AT, and the like are display items, and in particular, PV is a display item to be initially displayed. In the example of FIG. 3, 18 display items are represented.

1 to 3, the down key 1 is a key operated when the operator switches display items. For example, when the operator presses the down key 1, the left end of the row one row lower than the currently selected display item is displayed. To change to the column display item (if the currently selected display item is the column in the bottom row, the operation to change to the column in the leftmost column in the top row) Accepted.
In the case of FIG. 3, for example, when the currently selected display item is SV, when the operator presses down key 1, an operation to change the display item to P is accepted. When the currently selected display item is Fn, when the operator presses down key 1, an operation to change the display item to AM is accepted.
In this example, if the currently selected display item is the display item in the bottom row column, an example of a rolling type that accepts an operation to change to the leftmost column display item in the top row is shown. However, in the case of a type that does not perform rolling, for example, when the currently selected display item is Fn, even if the operator depresses the down key 1, an operation for switching the display item is not accepted. For this reason, for example, to change the display item to AM, it is necessary to press an up key 2 described later six times.

The up key 2 is a key operated when the operator switches display items. For example, when the operator depresses the up key 2, the display item is changed to the display item in the leftmost column in the row immediately above the currently selected display item. An operation to be performed (if the currently selected display item is a display item in the column on the top row, an operation to change to a display item in the leftmost column on the bottom row) is accepted.
In the case of FIG. 3, for example, when the currently selected display item is SV, when the operator presses the up key 2, an operation to change the display item to r-S is accepted. When the currently selected display item is AM, when the operator presses the up key 2, an operation for changing the display item to Fn is accepted.
Here, an example of a rolling type that accepts an operation to change to a display item in the leftmost column in the bottom row if the currently selected display item is a display item in the top row column is shown. However, in the case of a type that does not perform rolling, for example, when the currently selected display item is A-M, an operation for switching the display item is not accepted even if the operator presses the up key 2. Therefore, for example, to change the display item to Fn, it is necessary to press down key 1 six times.

The shift key 3 is a key operated when the operator switches display items. For example, when the operator presses the shift key 3, the operation is performed to change the display item to the right one column from the currently selected display item (currently selected). If the display item is a display item in the rightmost column, an operation for changing to a display item in the leftmost column is accepted.
In the case of FIG. 3, for example, when the currently selected display item is SV, when the operator presses the shift key 3, an operation for changing the display item to MV is accepted. When the currently selected display item is MV and the operator presses the shift key 3, an operation for changing the display item to PV is accepted.

The display device 10 is, for example, the display device shown in FIG. 2 (a) or 2 (b).
The hierarchical structure storage unit 11 includes a storage device such as a RAM or a ROM, for example, and stores item names (names) of a plurality of display items and a hierarchical structure of the plurality of display items (for example, the hierarchical structure of FIG. 3). doing. The hierarchical structure storage unit 11 constitutes a hierarchical structure storage unit.
The item-specific data storage unit 12 is composed of a storage device such as a RAM, for example, and stores item-specific data (measured values or set values) corresponding to the respective display items. When the item-specific data is a measured value, it is sequentially updated to a value measured by a sensor (not shown).

Under the instruction of the operation control unit 15, the display processing unit 13 performs processing for displaying the item name of the display item to be displayed and the item-specific data corresponding to the display item to be displayed on the display 10.
The key operation acceptance processing unit 14 performs a process of accepting a display item switching operation when the down key 1, the up key 2 or the shift key 3 is pressed as a display item switching operation by the operator. The down key 1, up key 2, shift key 3, and key operation reception processing unit 14 constitute a switching operation reception means.

The operation control unit 15 controls the operation of each processing unit of the display control device of FIG. 1 and sets the initial display target display item (PV in the example of FIG. 3) preset from the item-specific data storage unit 12. The corresponding item-specific data is read, and an instruction to display the item-specific data on the display 10 is output to the display processing unit 13.
The operation control unit 15 updates the display items to be displayed according to the switching operation received by the key operation reception processing unit 14 and the hierarchical structure stored in the hierarchical structure storage unit 11, and the item-specific data storage unit 12. The process reads out the item-specific data corresponding to the display item to be updated after the display, and outputs to the display processing unit 13 an instruction to switch the display content of the display 10 to the data corresponding to the display item to be updated. carry out.

Further, when the key operation acceptance processing unit 14 accepts a new switching operation, the operation control unit 15 resets the count time of the no-operation timer 19 to 0 (initializes the count time to 0), while the count of the no-operation timer 19 When the time reaches the no-operation time set by the no-operation time update unit 18 and the time is up, the display content of the display 10 is displayed for each item corresponding to the display item to be initially displayed (PV in the example of FIG. 3). A process of outputting an instruction to return to data to the display processing unit 13 is performed.
The display processing unit 13 and the operation control unit 15 constitute an initial display unit and a display switching unit.
The display processing unit 13, the operation control unit 15, and the no-operation timer 19 constitute display reset means.

The display item history update unit 16 performs a process of updating the display item history indicating the display item to be displayed updated by the operation control unit 15 every time the switching operation is received by the key operation reception processing unit 14.
The skill level evaluation unit 17 performs a process of evaluating the skill level of the switching operation by the operator based on the display item history updated by the display item history update unit 16.
In other words, the skill level evaluation unit 17 performs a deduction operation (a deduction target object) based on the switching operation received by the key operation reception processing unit 14 based on the display item update order indicated by the display item history updated by the display item history update unit 16. Operation) or adding operation (operation to be added), and if the switching operation corresponds to a deduction operation, the skill level of the switching operation by the operator is lowered, while the switching operation is added If it corresponds to an operation, a process for raising the evaluation of the switching operation by the operator is performed.
Here, the deduction operation is an operation of an operator considered to have a low skill level, and the point addition operation is an operation of an operator considered to have a high skill level.
The display item history update unit 16 and the skill level evaluation unit 17 constitute skill level evaluation means.
The no-operation time update unit 18 updates the no-operation time according to the skill level evaluated by the skill level evaluation unit 17 and sets the updated no-operation time in the no-operation timer 19. The no-operation time update unit 18 constitutes no-operation time update means.

If the non-operation timer 19 is not reset to 0 by the operation control unit 15 before the count time reaches the non-operation time set by the non-operation time update unit 18, the count time is incremented every time (count-up). When the no-operation time is reached, the time is up (the upper limit is reached).
That is, the no-operation timer 19 is a key operation reception processing unit between the time when the display content of the display 10 is switched by the operation control unit 15 and the time when the no-operation time set by the no-operation time update unit 18 is reached. 14 is a timer that times up when a new switching operation is not accepted.

1, the hierarchical structure storage unit 11, the item-specific data storage unit 12, the display processing unit 13, the key operation reception processing unit 14, the operation control unit 15, the display item history update unit 16, and the skill level Each of the evaluation unit 17, the no-operation time update unit 18, and the no-operation timer 19 is configured with dedicated hardware (for example, a semiconductor integrated circuit on which a CPU is mounted, or a one-chip microcomputer or the like). However, the display control device may be configured by a computer.
When the display control device is configured by a computer, the hierarchical structure storage unit 11 and the item-specific data storage unit 12 are configured on the internal memory or the external memory of the computer, and the display processing unit 13, the key operation reception processing unit 14, the operation control. Unit 15, display item history update unit 16, skill level evaluation unit 17, no-operation time update unit 18, and no-operation timer 19 are stored in a computer memory, and the computer CPU stores the program The program stored in the memory may be executed.
FIG. 4 is a flowchart showing the processing contents (display control method) of the display control apparatus according to Embodiment 1 of the present invention.

Next, the operation will be described.
In the present invention, in order to realize high operability regardless of which operator operates, the skill level of the switching operation by the operator is evaluated, and the no-operation timer 19 is evaluated according to the evaluation result of the skill level. It is characterized in that the no-operation time set in is updated.
Before specifically explaining the process of updating the non-operation time set in the non-operation timer 19, the basic operation of the display control device will be briefly described.

(1) Basic operation of the display control apparatus when the display 10 is mounted with two displays (display item display and data display) (in the case of FIG. 2A). 5 is a mode transition diagram showing a basic operation of the display control apparatus when two displays are mounted.
When the two display devices 10 are mounted, there are a normal mode and a setting mode. When the power is turned on, the normal mode is set, and the item name (name) of the display item to be initially displayed is used as the item name display device. In addition to displaying, item-specific data corresponding to the display item is displayed on the data display.
When the operator depresses the shift key 3 in the normal mode, the display item to be displayed is switched to the display item in the right column from the currently selected display item (the currently selected display item is the rightmost column). Display items in the leftmost column).
In addition, when the operator presses down key 1 in the normal mode, the display item to be displayed is switched to the display item in the leftmost column of the row immediately below the currently selected display item, and the operator presses the up key. When 2 is pressed, the display item to be displayed is switched to the display item in the leftmost column of the row one level higher than the currently selected display item.

If the display item can be changed, the operation mode is switched from the normal mode to the setting mode when the operator holds down the shift key 3 in the normal mode.
When the operator presses down key 1 in the setting mode, a change is made to lower the displayed item-specific data (setting value) corresponding to the currently selected display item.
In addition, when the operator presses the up key 2, a change is made to increase the displayed item-specific data (setting value) corresponding to the currently selected display item.
When the operator depresses the shift key 3 in the setting mode, the change target digit of the displayed item-specific data is changed.

When the operator depresses the shift key 3 in the setting mode, the change of the item-specific data by the down key 1 or the up key 2 is confirmed, and the operation mode is switched from the setting mode to the normal mode.
Even if an operation for switching the currently selected display item or an operation for changing the item-specific data is performed, the operation is performed until the no-operation time set by the no-operation time update unit 18 is reached. In the meantime, if the next operation is not performed, the display content of the item name display unit returns to the initial display target item name, and the display content of the data display unit corresponds to the initial display target display item. Return to itemized data.

(2) Basic operation of the display control apparatus in the case where one display unit 10 serves as both an item name display unit and a data display unit (in the case of FIG. 2B). It is a mode transition diagram which shows the basic operation | movement of the display control apparatus in case the device 10 serves as the item name indicator and the data indicator.
When one display unit 10 serves as both an item name display unit and a data display unit, there are an item name mode, a data mode, and a setting mode. The item name of the display item is displayed on the display 10. Thereafter, when the item name display time which is a preset time (details will be described in the second embodiment, the item name display time corresponds to the no-operation time) is reached, the operation mode is automatically changed to the data mode. Thus, the item-specific data corresponding to the display item to be initially displayed is displayed on the display 10.

If the item-specific data displayed on the display device 10 is item-specific data corresponding to the display item to be initially displayed, a data display time that is a preset time (details will be described in the second embodiment). Even if the data display time is equivalent to the no-operation time), the data for each item will continue to be displayed. However, if the data for each item corresponds to a display item other than the initial display target, the data display time When the operation mode is reached, the operation mode automatically becomes the item name mode, and the item name of the display item to be initially displayed is displayed on the display 10.
Even if the operator presses an arbitrary key, the operation mode becomes the item name mode, and the item name of the currently displayed display item is displayed on the display 10.

When the operator depresses the shift key 3 in the item name mode, the display item to be displayed is switched to the display item in the column to the right of the currently selected display item (the currently selected display item is displayed at the right end). If the display item is a column display item, the display item is switched to the display item in the leftmost column), and the item name of the display item after switching is displayed on the display 10.
Also, when the operator presses down key 1 in the item name mode, the display item to be displayed is switched to the display item in the leftmost column of the next lower row than the currently selected display item, and the operator is up. When the key 2 is pressed, the display item to be displayed is switched to the display item in the leftmost column of the row immediately above the currently selected display item, and the item name of the display item after switching is displayed on the display unit 10. .
Thereafter, when the item name display time, which is a preset time, is reached, the operation mode automatically becomes the data mode, and the item-specific data corresponding to the display item after switching is displayed on the display 10.

If the display item can be changed, the operation mode is switched from the data mode to the setting mode when the operator holds down the shift key 3 in the data mode.
When the operator presses down key 1 in the setting mode, a change is made to lower the displayed item-specific data (setting value) corresponding to the currently selected display item.
In addition, when the operator presses the up key 2, a change is made to increase the displayed item-specific data (setting value) corresponding to the currently selected display item.
When the operator depresses the shift key 3 in the setting mode, the change target digit of the displayed item-specific data is changed.

When the operator depresses the shift key 3 in the setting mode, the change of the item-specific data by the down key 1 or the up key 2 is confirmed, and the operation mode is switched from the setting mode to the data mode.
Even if an operation for switching the currently selected display item or an operation for changing data for each item is performed, the operation is performed until the no-operation time set by the no-operation time update unit 18 is reached. If the next operation is not performed during this period, the operation mode returns to the item name mode, and the display content of the display 10 returns to the item name of the display item to be initially displayed.

Here, the basic operation of the display control apparatus has been described with reference to FIG. 5 and FIG. 6, but this operation is merely an example, and the basic operation of the display control apparatus is another operation. Needless to say.
The characteristic processing content of the present invention (processing for updating the no-operation time set in the no-operation timer 19) will be specifically described below.
Here, for simplification of description, the display device 10 is described as having two display devices. However, an essential part of the characteristic processing content is that one display device 10 has an item name. The same applies to the case of serving as both a display for data and a data display.

The hierarchical structure storage unit 11 stores a hierarchical structure of a plurality of display items as shown in FIG.
Here, for convenience of explanation, it is assumed that PV is set as a display item to be initially displayed.
When the power is turned on, the operation control unit 15 changes the operation mode to the normal mode, and outputs an instruction to display the item name of PV, which is the display item to be initially displayed, on the display unit 10 to the display processing unit 13.
Further, the operation control unit 15 reads out the item-specific data corresponding to the PV, which is the display item to be initially displayed, from the item-specific data storage unit 12 and displays an instruction to display the item-specific data on the display unit 10. 13 is output.
Thereby, as shown in FIG. 2A, the display processing unit 13 displays the item name of PV, which is the display item to be initially displayed, on the upper display, and item-specific data corresponding to PV (see FIG. 2). In the example of 2 (a), “28.7” is displayed on the lower display (step ST1 in FIG. 4).

When the item name of PV that is a display item to be initially displayed and item-specific data corresponding to PV are displayed, when the operator desires to switch the display item to be displayed, the down key 1 and the up key 2 Alternatively, an operation of pressing the shift key 3 is performed.
For example, if the desired display item is dF and the hierarchical structure of FIG. 3, if the down key 1 is pressed twice and then the shift key 3 is pressed twice, there is no wasteful switching operation. The display item to be displayed can be switched from PV to dF which is a desired display item.
However, if the operator is not familiar with the hierarchical structure of a plurality of display items, it is not always possible to switch to a desired display item without useless switching operation.

FIG. 7 to FIG. 9 are explanatory diagrams showing a switching operation in which the skill level is deducted when it is not possible to switch to a desired display item without useless switching operation.
In the example of FIG. 7, the operator does not know that the line of dF that is the desired display item is two lines below the line of PV that is the display item to be initially displayed. After that, the up key 2 in the reverse direction is pressed once. Since it can be determined that the switching operation is useless at this point, a deduction is made.

In the example of FIG. 8, since the operator does not know that the line of dF that is the desired display item is two lines below the line of PV that is the display item to be initially displayed, the down key 1 is continuously displayed. , And the leftmost column has been circled once. For example, when selecting the desired display item dF, the shift key 3 must be pressed when the leftmost Pb of the row of dF is displayed. It is in a state where it cannot recognize that it should not be. In this way, when the leftmost column makes one round in the vertical direction, it can be determined that it is a useless switching operation, so a deduction is made.
In the example of FIG. 9, when the operator presses down key 1 twice and then shift key 3 is pressed twice, the operator has overlooked that the display item has been switched to dF which is a desired display item. 3 is pressed to return to Pb and complete one round in the horizontal direction. Since it can be determined that the switching operation is useless at this point, a deduction is made.

When the operator presses down key 1, up key 2 or shift key 3 (step ST2), key operation reception processing unit 14 receives a display item switching operation associated with the pressing (step ST3).
When the key operation acceptance processing unit 14 accepts a display item switching operation, the operation control unit 15 updates the display items to be displayed according to the switching operation and the hierarchical structure stored in the hierarchical structure storage unit 11 (step ST4).
For example, when the currently selected display item is PV, if the operator presses down key 1, the display item to be newly displayed is determined as P, and if the operator presses up key 2, a new display is displayed. If the target display item is determined to be r-S, and the operator presses the shift key 3, the new display target display item is determined to be SV.
When the currently selected display item is MV, if the operator presses the down key 1, the display item to be newly displayed is determined as P, and if the operator presses the up key 2, a new display is displayed. If the target display item is determined to be r-S, and the operator presses the shift key 3, the new display target display item is determined to be PV.

Here, when the currently selected display item is MV, when the operator presses the down key 1, the display item P in the leftmost column of the next lower row is determined as a new display target display item. In this example, a new display target display item can be uniquely determined from the switching operation received by the key operation reception processing unit 14 and the hierarchical structure stored in the hierarchical structure storage unit 11. For example, d in the same column as the MV in the next lower row may be determined as a new display item to be displayed.
Similarly, when the currently selected display item is MV, when the operator depresses the up key 2, r-S, which is the display item in the leftmost column of the upper row, is displayed as a new display target display item. In this example, the AT in the rightmost column of the upper row may be determined as a new display item to be displayed.

When the display control unit 15 updates the display item to be displayed, the operation control unit 15 outputs an instruction to display the item name of the display item to be updated on the display 10 to the display processing unit 13.
Further, the operation control unit 15 reads out the item-specific data corresponding to the display item to be updated after the update from the item-specific data storage unit 12 and displays an instruction to display the item-specific data on the display unit 10. Output to.
Thereby, the display processing unit 13 displays the item name of the display item to be updated on the upper display unit, and displays the item-specific data corresponding to the display item to be updated on the lower display unit. (Step ST5).

When the operation control unit 15 outputs an instruction to display the updated display target display item to the display processing unit 13, the operation control unit 15 resets the count time of the no-operation timer 19 to 0 (step ST6).
The operation control unit 15 outputs an instruction to display the updated display target display item to the display processing unit 13 every time the key operation reception processing unit 14 receives a new switching operation, and counts the no-operation timer 19. Although the time is reset to 0, since the key operation reception processing unit 14 does not accept a new switching operation after the count time of the no-operation timer 19 is finally reset to 0, there is no count time of the no-operation timer 19. When the no-operation time set by the operation time update unit 18 is reached, the no-operation timer 19 is timed up.

When the no-operation timer 19 expires (step ST7), the operation control unit 15 outputs an instruction to return the display content of the upper display to the item name of PV, which is the display item to be initially displayed, to the display processing unit 13. .
In addition, the operation control unit 15 outputs to the display processing unit 13 an instruction to return the display content of the lower display to the item-specific data corresponding to the PV that is the display item to be initially displayed.
As a result, the display processing unit 13 displays the item name of PV, which is the display item to be initially displayed, on the upper display, and displays the item-specific data corresponding to PV on the lower display (step ST1). ).
FIG. 10 shows that the non-operation timer 19 is timed out without changing the setting, and immediately after the display returns to the display item of the initial display target (the non-operation timer is displayed while the display item of the initial display target is being displayed). It is explanatory drawing which shows switching operation which performs switching operation (before 19 time-up) and a skill level is deducted.
In the example of FIG. 10, the AT item is displayed by chance, but the target display item cannot be reached during the switching operation, and the time is up after being confused and displayed on the initial display target display item. Immediately after returning to, the switching operation is performed again, and it is assumed that the target display item is about to be reached.

The display item history update unit 16 updates the display item history indicating the display items to be displayed updated by the operation control unit 15 every time the key operation reception processing unit 14 receives a switching operation (step ST8).
For example, when the display item update order is shown in FIG. 7, the display item history is updated as follows.
PV → P → Pb → T → (Pb) Display item history is reset for deduction operation Pb → Pr → dF Display item history update When the display item update order is as shown in FIG. It is updated as follows.
PV->P->Pb->Pr->dF-> (Pb) Reset display item history for deduction operation Pb->Pr-> dF Display item history update When the skill level is updated, the display item history is reset and currently displayed Is updated as the starting point of the switching operation.

The skill level evaluation unit 17 calculates the evaluation value V of the skill level of the switching operation by the operator based on the update order of the display items indicated by the display item history updated by the display item history update unit 16 and the update of the set value ( Step ST9).
Hereinafter, the calculation process of the evaluation value V by the skill level evaluation unit 17 will be specifically described.

The skill level evaluation unit 17 refers to the display item update order indicated by the display item replacement history updated by the display item history update unit 16 and determines whether or not the current switching operation by the operator corresponds to a deduction operation. If the current switching operation corresponds to a deduction operation, as shown in the following equation (1), a deduction point P _d (for example, “1”) preset from the current skill level evaluation value V The skill level evaluation value V is updated by subtracting. The initial value of the skill level evaluation value V is set in advance.
V = V−P _d (1)
When V, which is the calculation result of Expression (1), is negative, V = 0.

As the switching operation of the operator corresponding to the deduction operation, for example, switching operations as shown in the following (1) to (6) are conceivable. However, the switching operations shown in (1) to (6) are merely examples, and other switching operations may correspond to deduction operations.
Further, the number of points to be deducted / the number of points for the deduction operation or the later-described addition operation may be appropriately adjusted according to the difference in the structure of display items and the operation method for each apparatus.
(1) When the operator depresses the down key 1 and then depresses the up key 2, this is a useless operation for returning the display item to be displayed to the original, and corresponds to a deduction operation (see FIG. 7).
Similarly, when the operator depresses the up key 2 and then depresses the down key 1, it corresponds to a deduction operation.
(2) When the operator continuously presses down key 1 (or up key 2) and the display item to be displayed returns to its original state (when it makes one round in the vertical direction), it is a useless operation. This corresponds to the deduction operation (see FIG. 8).
(3) When the operator continuously presses the shift key 3 and the display item to be displayed returns to its original state (when the display item makes one round in the horizontal direction), it is a useless operation, and thus corresponds to a deduction operation (see FIG. 9).
(4) When the operator depresses the shift key 3 and moves in the horizontal direction and then depresses the down key 1 or the up key 2, the display item to be displayed returns to the display item in the leftmost column. Applicable (Even if the display item to be displayed returns to the display item in the leftmost column, it is not necessarily a wasteful operation, but it is highly likely that it is a wasteful operation, so it corresponds to a deduction operation).

(5) When the time of the non-operation timer 19 occurs without changing the setting and the display returns to the display item to be initially displayed, immediately thereafter (no operation while displaying the display item to be initially displayed) If the operator performs a switching operation (before the timer 19 expires), it corresponds to a deduction operation.
In the example of FIG. 10, pressing down the down key 1 when moving from PV to P after returning to PV corresponds to the deduction operation. Thereafter, since the operator continues the switching operation and reaches the target display item dF, if the setting is changed in the target display item, points are added as described later.
(6) In the case where the down key 1 and the up key 2 are of a type that does not perform rolling, if the display item switching operation is not accepted, it is assumed that a deduction operation has been performed (for example, the currently selected display item) This is the case when the operator presses the down key 1 when the key is Fn, or when the operator presses the up key 2 when the currently selected display item is AM.

Further, the skill level evaluation unit 17 refers to the update order of the display items indicated by the display item history updated by the display item history update unit 16, and determines whether or not the current switching operation by the operator corresponds to a point addition operation. If the current switching operation corresponds to the point addition operation, as shown in the following equation (2), the point number P _u (for example, “1”) set in advance from the evaluation value V of the current skill level ) Is added to update the proficiency evaluation value V.
V = V + P _u (2)
When V, which is the calculation result of Expression (2), is larger than the evaluation value V _max of the maximum skill level, V = V _max is set.

As an operator switching operation corresponding to the point addition operation, for example, switching operations as shown in the following (1) to (4) are conceivable. However, the switching operations shown in (1) to (4) are merely examples, and other switching operations may also correspond to point addition operations.
(1) When the setting change is completed, it corresponds to the point addition operation.
(2) When the setting change is completed, if the switching operation is performed more than a preset number of times from the start of the display item switching operation to the display item for which the setting change has been performed, an additional operation is performed. It corresponds to (bonus additional points).
(3) When the setting change is completed, if the next switching operation is started without the time-up of the no-operation timer 19 after completion of the previous setting change, it corresponds to the adding operation (bonus adding point).

(4) When the setting change is completed, start the switching operation, and press either the down key 1 or the up key 2 to advance to a line with a desired display item. When the key operation is performed, it corresponds to a point addition operation (bonus point addition).
FIG. 11 is an explanatory diagram showing a switching operation corresponding to the point addition operation (4). For example, when the display item at the switching operation start point is r-S and the desired display item is t, when the down key 1 is pressed to advance to the line with the desired display item t, the number of operations is four times. However, when the up key 2 is pressed to advance to a line having a desired display item t, the number of operations is three, and the number of operations is decreased only once. Therefore, when the up key 2 is pressed to advance to a line with a desired display item t, and further to t, the setting is changed, which corresponds to a point addition operation.

When the skill level evaluation unit 17 calculates the evaluation value V of the skill level of the switching operation by the operator, the no-operation time update unit 18 performs no operation according to the skill value evaluation value V as shown in the following equation (3). The operation time T _Nop is updated, and the updated no-operation time T _Nop is set in the no-operation timer 19 (step ST10).
T _Nop = T _max − (T _max −T _min ) × V / V _max (3)
In Expression (3), T _max is a preset maximum no-operation time, and T _min is a preset minimum no-operation time.
Therefore, for example, the maximum no-operation time T _max is 10 seconds, the minimum no-operation time T _min is 2 seconds, the maximum skill level evaluation value V _max is 10, and the skill level evaluation calculated by the skill level evaluation unit 17 is evaluated. If the value V is 10, the updated no-operation time T _Nop is 6 seconds as shown in the following equation (4).
T _Nop = 10− (10−2) × _10/20 = 6 (seconds) (4)

As a result, the no-operation timer 19 is reset by the key operation reception processing unit 14 after the count time is reset to 0 by the operation control unit 15 and before the updated no-operation time T _Nop is reached. Is accepted and the time is up if the count time is not reset to zero.
The display control apparatus in FIG. 1 repeatedly executes the processes of steps ST1 to ST10 until the series of processes is completed (step ST11).

As is apparent from the above, according to the first embodiment, every time a switching operation is received by the key operation reception processing unit 14, the display item history indicating the display items to be displayed updated by the operation control unit 15 is stored. A display item history update unit 16 to be updated, and a skill level evaluation unit 17 that evaluates the skill level of the switching operation by the operator based on the update order of the display items indicated by the display item history updated by the display item history update unit 16 The no-operation time update unit 18 updates the no-operation time T _Nop according to the skill level evaluated by the skill level evaluation unit 17, and sets the updated no-operation time T _Nop in the no-operation timer 19. since the configuration, so that no-operation time T _Nop according to operation of the operator is updated, as a result, no matter which operator operates, high operating An effect that can be achieved. Further, by evaluating the skill level for each switching operation, even when the same operator operates, there is an effect that high operability according to different proficiency levels depending on operation items can be realized.

According to the first embodiment, the current switching operation by the operator corresponds to the deduction operation or the point addition operation with reference to the update order of the display items indicated by the display item history updated by the display item history update unit 16. If the current switching operation corresponds to a deduction operation, the skill level evaluation is lowered and updated so that the no-operation time T _Nop becomes longer, and the current switching operation corresponds to a point addition operation. Then, the skill level is evaluated and updated so that the no-operation time T _Nop is shortened, so the no-operation time T _Nop corresponding to the skill level of the operator is updated in real time every time the operator performs a switching operation. As a result, even if the operator changes in the middle, there is an effect that the no-operation time T _Nop can be set promptly for the operator who has changed.

Embodiment 2. FIG.
In the first embodiment, it is assumed that the display 10 has two displays, and the no-operation time update unit 18 updates the no-operation time T _Nop. When both the name display and the data display are used, the non-operation timer 19 counts up the count time for the item name display time and the count time for the data display time, and the operation control unit 15 When a new switching operation is accepted by the key operation acceptance processing unit 14, the count times thereof are reset to 0, so that it is necessary to update the preset item name display time and data display time as no-operation time. .

In this case, the no-operation time update unit 18 _{calculates the} item name display time T _{Nop1 that} is the no-operation time and the data display time T _Nop2 that is the no-operation time as shown in the following formulas (5) and (6). Update.
T _Nop1 = T _max1 − (T _max1 −T _min1 ) × V / V _max1 (5)
In Equation (5), T _max1 is a preset maximum item name display time, and T _min1 is a preset minimum item name display time.
T _Nop2 = T _max2 − (T _max2 −T _min2 ) × V / V _max2 (6)
In Equation (6), T _max2 is a preset maximum data display time, and T _min2 is a preset minimum data display time.

Accordingly, the no-operation timer 19 is set between the time when the count time for the item name display time is reset to 0 by the operation control unit 15 and the time until the item name display time T _Nop1 that is the no-operation time after the update is reached. If a new switching operation is accepted by the key operation acceptance processing unit 14 and the count time is not reset to 0, time-up occurs. Thereby, the operation control part 15 outputs the instruction | indication which switches the display content of the display 10 to the item-specific data corresponding to the display item currently displayed to the display process part 13, and the display content of the display 10 is switched.
Further, the no-operation timer 19 is operated by the key operation after the count time for the data display time is reset to 0 by the operation control unit 15 until the data display time T _Nop2 that is the updated no-operation time is reached. If a new switching operation is accepted by the acceptance processing unit 14 and the count time is not reset to 0, time-up occurs. Thereby, the operation control part 15 outputs the instruction | indication which switches the display content of the display 10 to the item name of the display item of initial display object to the display process part 13, and the display content of the display 10 is switched.

Embodiment 3 FIG.
In the first embodiment, when two display devices are mounted, when the display item whose settings can be changed is in the normal mode, the operation mode is changed from the normal mode to the setting mode when the operator holds down the shift key 3 for a long time. In the setting mode, when the operator presses the shift key 3 for a long time, the change of the item-specific data by the down key 1 or the up key 2 is confirmed.
In addition, when one display unit 10 serves as both an item display unit and a data display unit, when the display item whose setting can be changed is in the data mode, if the operator depresses the shift key 3 for a long time, the operation In the example, the mode is switched from the data mode to the setting mode, and when the operator presses the shift key 3 for a long time in the setting mode, the change of the item-specific data by the down key 1 or the up key 2 is confirmed.

In the third embodiment, the key operation reception processing unit 14 is only in the case where the pressing time of the shift key 3 by the operator (the time during which the operator keeps pressing the shift key 3) is longer than the preset long pressing time T _Long. A long press operation of the shift key 3 is instructed to instruct execution of a predetermined process (for example, an operation mode switching process, an item-specific data change confirmation process, etc.).
In this case, when the skill level evaluation value V by the skill level evaluation unit 17 increases, the operation control unit 15 updates the long press time T _Long so that the skill level evaluation unit 17 evaluates the skill level. When the value V decreases, the long press time T _Long is updated so as to increase.
Thereby, the long press operation of the shift key 3 by the operator can be controlled according to the evaluation value V of the skill level.
In the third embodiment, the key operation acceptance processing unit 14 constitutes a long press operation acceptance unit, and the operation control unit 15 constitutes a long press time update unit.

Embodiment 4 FIG.
In the first embodiment, when the operator depresses the down key 1 in the setting mode, a change is made to lower the displayed item-specific data (setting value) corresponding to the currently selected display item, and the operator is up. In the example, when the key 2 is pressed, the item-by-item data (set value) being displayed corresponding to the currently selected display item is changed.
In the fourth embodiment, when the operator continues to press the up key 2, the key operation reception processing unit 14 continuously increases the displayed item-specific data (setting value) corresponding to the currently selected display item. As an operation, a long press operation of the up key 2 by the operator is accepted.
Further, when the operator continues to press down the down key 1, the key operation acceptance processing unit 14 accepts a long press operation of the down key 1 by the operator as an operation for continuously lowering the item-specific data (setting value). To do.

When the key operation acceptance processing unit 14 accepts a long press operation of the up key 2, the operation control unit 15 displays items that are displayed at a preset change cycle C during the long press operation. A process of increasing another data (setting value) is performed.
For example, if the operation time of the long press operation of the up key 2 is 10 seconds, suppose that the change cycle C is set to 0.5 seconds, and the increment of the set value for each change cycle is set to 1. The value of the item-specific data is increased by 20 (= 1 × 10 / 0.5).

In addition, when the key operation acceptance processing unit 14 accepts a long press operation of the down key 1, the operation control unit 15 displays the change cycle C that is set in advance during the long press operation. Execute the process to lower the item-specific data (setting value).
For example, if the operation time of the long press operation of the down key 1 is 8 seconds, it is assumed that the change cycle C is set to 0.5 seconds, and the amount of decrease in the set value for each change cycle is set to 1. For example, the value of the item-specific data is reduced by 16 (= 1 × 8 / 0.5).

The operation control unit 15 manages a preset change cycle C. If the skill level evaluation value V by the skill level evaluation unit 17 increases, the operation control unit 15 updates the change cycle C so that the change cycle C becomes shorter. If the evaluation value V of the skill level by the degree evaluation unit 17 decreases, the change period C is updated so as to become longer.
Thereby, according to the evaluation value V of the skill level, it is possible to control a long press operation of the down key 1 or the up key 2 by the operator (operation for continuously lowering / raising item-specific data (setting value)). .
In the fourth embodiment, the key operation acceptance processing unit 14 constitutes a continuous change operation acceptance unit, and the operation control unit 15 constitutes a data value change unit and a change cycle update unit.

Embodiment 5. FIG.
In the first embodiment, the key operation reception processing unit 14 receives a display item switching operation that occurs when the down key 1, the up key 2, or the shift key 3 is pressed as the display item switching operation by the operator. In the fifth embodiment, if the key operation acceptance processing unit 14 further has a skill level evaluation value V by the skill level evaluation unit 17 higher than a preset threshold value T _v1 , the key operation reception processing unit 14 has a plurality of hierarchical structures shown in FIG. Display item changing operation for displaying a plurality of display items having a hierarchical structure different from the display item (for example, a display item to be confirmed by a user having expert knowledge) (for example, pressing down key 1 and up key 2 at the same time) while receiving an operation) to, if lower than the evaluation value V threshold T _v1 of skill by skilled evaluation unit 17, so as not to accept the displayed items change operation Good.
The operation control unit 15 displays an instruction to display a display item different from the plurality of display items according to the hierarchical structure of FIG. 3 on the display unit 10 when the display item changing operation is received by the key operation reception processing unit 14. 13 is output.
Thereby, the effect that a special display item can be shown only to a user with high skill is acquired.

Embodiment 6 FIG.
In the first embodiment, when two display devices are mounted, when the display item whose settings can be changed is in the normal mode, the operation mode is changed from the normal mode to the setting mode when the operator holds down the shift key 3 for a long time. It was possible to change the item-specific data (setting value).
In the sixth embodiment, only when the skill level evaluation value V by the skill level evaluation unit 17 is higher than a preset threshold value _Tv2 , when the operator presses the shift key 3 for a long time, the key operation reception processing unit 14 An operation for changing the operation mode from the normal mode to the setting mode is accepted, and when the skill level evaluation value V by the skill level evaluation unit 17 is lower than a preset threshold value _Tv2 , the operator holds down the shift key 3 for a long time. Even so, the operation mode is not changed from the normal mode. Thereby, it is possible to limit the change operation only to a user whose skill level is less than a certain value.
Regarding the limitation of the change operation, it goes without saying that the change operation from the data mode to the setting mode is similarly performed when one display unit 10 serves as both the item display unit and the data display unit.
In the sixth embodiment, the key operation acceptance processing unit 14 constitutes a data change operation acceptance means.

Embodiment 7 FIG.
In the first embodiment, an example is shown in which the key operation reception processing unit 14 receives a display item switching operation in response to pressing of the down key 1, the up key 2, or the shift key 3 as a display item switching operation by the operator.
In the seventh embodiment, unlike the first embodiment, the display item switching operation is restricted.
That is, in the seventh embodiment, when the skill level evaluation value V by the skill level evaluation unit 17 becomes equal to or lower than a preset threshold value _Tv3 , the key operation reception processing unit 14 subsequently performs a display item switching operation by the operator. Is temporarily stopped, and the warning content is displayed on the display 10. However, after stopping the reception of the switching operations, for example, by evaluation value V of skill is initialized, the evaluation value V of proficiency is higher than the threshold value T _v3, acceptance of switching operation of display items by the operator Is resumed.
Thereby, it is possible to add a certain restriction to the display item switching operation due to mischief or erroneous operation of the child.

Embodiment 8 FIG.
In the first embodiment, the skill level evaluation unit 17 determines the skill level of the switching operation by the operator based on the update order of the display items indicated by the display item history updated by the display item history update unit 16 and the update of the set value. Although the calculation of the evaluation value V has been shown, in this eighth embodiment, when the switching operation is not accepted by the key operation acceptance processing unit 14 continuously for a preset time, the skill level evaluation unit 17 The skill level evaluation value V may be returned to the initial value.
