Provided is an implementation mode.
Fig. 1 is a diagram showing a functional configuration of a display control device 10 according to an embodiment of the present invention. The display control apparatus 10 shown in fig. 1 includes a display mode switching unit 11 and a display control unit 12.

In this case, the display mode switching unit 11 has a function of maintaining the size, display position, and the like of the waveform displayed before and after switching the display mode. The function of the display mode switching unit 11 will be described in detail later. The display control unit 12 displays the input data as a waveform on the screen. At this time, the display control unit 12 displays the waveform in accordance with the display mode switched by the display mode switching unit 11.
The controller 20 inputs a command to the servo amplifier 30. The servo amplifier 30 controls the rotation of the motor 40 by supplying the motor 40 with electric power generated based on a command from the controller 20. The controller 20, the servo amplifier 30, and the motor 40 constitute a positioning control system that controls the operation of the machine driven by the motor 40. The display control device 10 can receive input data from the positioning control system, and has both the adjustment function of the servo amplifier 30 and the debugging function of a computer program for operating the controller 20. In fig. 1, the display control device 10 displays input data from the positioning control system including the controller 20, the servo amplifier 30, and the motor 40 as a waveform, but the present invention is not limited to this. The input data to the display control apparatus 10 is not limited to the positioning control system, and may be any input data.
Fig. 2 is a diagram showing a hardware configuration of the display control apparatus 10 shown in fig. 1. The display control apparatus 10 includes a memory 101, a processor 102, an input device 103, and an output device 104. The memory 101 is a storage device that stores a control program executed by the processor 102, various data used during execution of the control program by the processor 102, and the like. Here, the memory 101 is, for example, a nonvolatile or volatile semiconductor memory such as a ram (random Access memory), a rom (read Only memory), a flash memory, an eprom (erasable Programmable rom), and an eeprom (electrically eprom), a magnetic disk, a flexible disk, an optical disk, a compact disk, a mini disk, and a dvd (digital Versatile disk). The processor 102 is a cpu (central Processing unit), which is also called a central Processing unit, a Processing unit, an arithmetic unit, a microprocessor, a microcomputer, a dsp (digital Signal processor), or the like. The input device 103 is a mouse, a touch sensor, a keyboard, or the like. The output device 104 is a display device, a speaker, or the like. The processor 102 can realize the functions of the display mode switching unit 11 and the display control unit 12 of the display control device 10 by reading the control program stored in the memory 101 and executing the read control program. The input device 103 and the output device 104 are used when the processor 102 executes a control program.
Fig. 3 is an explanatory diagram of terms used when the display control apparatus 10 shown in fig. 1 displays a waveform in a display mode specified by upper and lower limit values. Before describing a display method of a waveform executed by the display control apparatus 10, terms used in the following description will be described. In the upper and lower limit value designation display mode, a region in which the waveform is displayed is referred to as a display region M. The upper end of the vertical axis of the display region M is referred to as an upper limit Ymax, and the lower end of the vertical axis of the display region M is referred to as a lower limit Ymin. The number of scales displayed in the display region M is referred to as a scale number X. The value of the interval of the plurality of scales is referred to as a scale interval value Z. In fig. 3, the waveform is displayed by specifying the upper and lower limit values on the vertical axis, but the present technique may be applied to a display control device that displays the waveform by specifying the upper and lower limit values on the horizontal axis.
Fig. 4 is an explanatory diagram of terms used when the display control apparatus 10 shown in fig. 1 displays a waveform in a scale interval value designation display mode. In the scale interval value designation display mode, a region in which the waveform is displayed is referred to as a display region N. The upper end value of the vertical axis of the display region N is referred to as an upper limit value Pmax, and the lower end value of the vertical axis of the display region N is referred to as a lower limit value Pmin. The number of scales on the vertical axis displayed in the display region N is referred to as a scale number T, and the scale interval on the vertical axis is referred to as a scale interval value S. In fig. 4, the waveform is displayed by designating the scale interval value S on the vertical axis, but the present technology may be applied to a display control device that displays the waveform by designating the scale interval value S on the horizontal axis.
Fig. 5 is a diagram showing an operation method when the display control apparatus 10 according to the embodiment of the present invention displays a waveform in a display mode specified by an upper limit value and a lower limit value. In the upper and lower limit value designation display mode, the display control unit 12 can designate the upper limit value Ymax and the lower limit value Ymin of the waveform display region M. For example, if a double-click operation using a mouse, which is the input device 103, is detected in the waveform display area M, the display control unit 12 displays a screen on which the upper limit value Ymax and the lower limit value Ymin can be edited. After that, if the input of the numerical value by the keyboard is detected, the display control unit 12 can set the input value as the upper limit value Ymax and the lower limit value Ymin. The method of specifying the upper limit value Ymax and the lower limit value Ymin is not limited to this. The display control unit 12 may display an icon for switching to a mode in which the upper limit value Ymax and the lower limit value Ymin are input on the screen, and if an operation of selecting the icon is detected, the upper limit value Ymax and the lower limit value Ymin can be input. The display control unit 12 may display an up-down key for changing the upper limit value Ymax and the lower limit value Ymin on the screen in accordance with each numerical value. The display control unit 12 changes the numerical value by a predetermined number according to the operation each time the operation of the displayed up-down key is detected, and displays the waveform based on the changed numerical value. Fig. 5 shows a state in which the upper limit value Ymax is 100 and the lower limit value Ymin is 0 are specified.
The display control unit 12 can enlarge or reduce the display area M in accordance with the operation while maintaining the upper limit value Ymax and the lower limit value Ymin if the drag operation of the mouse is detected in the vicinity of the upper limit value Ymax or the vicinity of the lower limit value Ymin of the display area M. When the display area M is enlarged or reduced, the display control unit 12 changes the size of the waveform and the number X of gradations on the vertical axis of the display area M in accordance with the size of the display area M. In the example of fig. 5, if the display area M is reduced, the number of gradations X becomes 2, and if the display area M is enlarged, the number of gradations X becomes 4.
Fig. 6 is a diagram showing an operation method when the display control apparatus 10 according to the embodiment of the present invention displays a waveform in a scale interval value designation display mode. In the scale interval value designation display mode, the scale interval value S can be designated in the waveform display region N. The display control unit 12 displays a screen on which the input of the scale interval value S is received if the double-click operation of the mouse is detected in the display area N. If the scale interval value S is input by the keyboard, the display control section 12 displays the waveform based on the input scale interval value S. The display control unit 12 can enlarge or reduce the display area N in accordance with the operation while maintaining the scale interval value S if the drag operation of the mouse is detected in the vicinity of the upper limit value Pmax or the vicinity of the lower limit value Pmin of the display area N. The display control unit 12 changes the number of scales T according to the size of the display area N at this time.
Fig. 7 is an explanatory diagram of an operation for switching the manner in which the display control device 10 shown in fig. 1 displays a waveform. The display control unit 12 can display the waveform display screen 300 shown in fig. 7. The waveform display screen 300 includes a plurality of display regions M for displaying a plurality of waveforms, respectively. Specifically, the waveform display screen 300 includes 2 display regions M-1 and M-2. The waveform 301a is displayed in the display region M-1 in the upper-lower-limit-value-specified display mode, and the waveform 302a is displayed in the display region M-2 in the upper-lower-limit-value-specified display mode. In the waveform display screen 300, display mode display areas 303 and 304 for displaying the display mode of the waveform are provided corresponding to the display areas M-1 and M-2, respectively, and the display mode of the waveform currently displayed is indicated. The waveform display screen 300 includes a switching combo box 305, and the switching combo box 305 instructs switching of the display mode in which each of the waveform 301a and the waveform 302a is displayed. When the waveform 301a or 302a to be operated is selected, the upper and lower limit value designation display mode or the scale interval value designation display mode can be selected by switching the combo box 305.
Fig. 8 is a flowchart showing an operation of the display mode switching unit 11 shown in fig. 1. The operation shown in fig. 8 is started when an operation of switching the display mode is detected. The display mode switching unit 11 first determines whether or not the display mode is currently being displayed in the upper and lower limit value designation display mode (step S201).
If the display is not performed in the upper and lower limit value designation display mode (No in step S201), the process proceeds to step S215 from step S211 in which the scale interval value designation display mode is switched to the upper and lower limit value designation display mode. The display mode switching unit 11 sets the upper limit value Ymax, which is designated to display the waveform in the upper limit value designation display mode, to the upper limit value Pmax of the display area N currently displayed in the scale interval value designation display mode (step S211). Next, the display mode switching unit 11 sets the lower limit value Ymin designated to display the waveform in the upper limit value designation display mode as the lower limit value Pmin of the display region N currently displayed in the scale interval value designation display mode (step S212). The display mode switching unit 11 sets the number X of the scale in the display region M in which the waveform is displayed in the upper and lower limit value designated display modes to the number T of the scale in the display region N currently displayed in the scale interval value designated display mode (step S213). Then, the display mode switching unit 11 sets the display area M in which the waveform is displayed in the upper and lower limit value designation display modes as the display area N currently displayed in the scale interval value designation display mode (step S214). If the setting shown in step S211 to step S214 ends, the display mode switching unit 11 causes the display control unit 12 to display the input data as a waveform in the display mode specified by the upper and lower limit values (step S215).
Fig. 9 is a diagram showing switching of the display control device 10 according to the embodiment of the present invention from the scale interval value designation display mode to the upper limit value designation display mode. The display mode switching unit 11 inherits the set value related to the display before switching to the display mode after switching so that the change of the displayed waveform before and after switching is small. When switching from the scale interval value designation display mode to the upper and lower limit value designation display mode, the display mode switching unit 11 calculates an upper limit value Pmax and a lower limit value Pmin of the display region N in which the waveform is currently displayed in the scale interval value designation display mode as an upper limit value Ymax and a lower limit value Ymin designated in the upper and lower limit value designation display mode. In the example of fig. 9, since the upper limit value Pmax is 99 and the lower limit value Pmin is 0, the display mode switching unit 11 sets the upper limit value Ymax to 99 and the lower limit value Ymin to 0. The display mode switching unit 11 inherits the arrangement of the display region N and the number of scales T to 3 before and after switching the display mode, and sets the number of scales X to 3.
The explanation returns to fig. 8. When the display is performed in the upper and lower limit value designation display mode (Yes in step S201), the process proceeds to step S230 from step S221 in which the upper and lower limit value designation display mode is switched to the scale interval value designation display mode. The display mode switching unit 11 calculates a scale interval value Z of the display area M currently displayed in the upper and lower limit value designated display modes (step S221). The scale interval value Z can be calculated by dividing the difference between the upper limit value Ymax and the lower limit value Ymin of the vertical axis of the display region M by the number of scales X. That is, the relationship of Z ═ y (Ymax-Ymin)/X holds.
If the scale interval value Z is calculated, the display mode switching unit 11 determines whether or not the calculated scale interval value Z is completely divided (step S222). When the scale interval value Z is divided (Yes in step S222), the display mode switching unit 11 sets the upper limit value Ymax and the lower limit value Ymin of the upper limit value designation display mode to the upper limit value Pmax and the lower limit value Pmin (step S223). That is, Pmax is Ymax and Pmin is Ymin. Therefore, the upper limit value Ymax and the lower limit value Ymin currently specified in the upper limit value specified display mode and the lower limit value Ymin are directly inherited to the scale interval value specified display mode. Then, the display mode switching unit 11 sets the number of gradations T of the display area N in which the waveform is displayed in the scale interval value designation display mode to the number of gradations X of the display area M in which the waveform is currently displayed in the upper and lower limit value designation display modes (step S224). Then, the display mode switching unit 11 sets the display area N in which the waveform is displayed in the scale interval value designation display mode as the display area M in which the waveform is currently displayed in the upper limit value designation display mode and the lower limit value designation display mode (step S225). If the setting shown in step S223 to step S225 is finished, the display mode switching part 11 causes the display control part 12 to display the input data as a waveform in the scale interval value designation display mode (step S226).
When the division of the scale interval value Z is not complete (No in step S222), the display mode switching unit 11 adjusts the scale interval value Z (step S230). If the scale interval value Z is not divided completely, if the value corresponding to the scale is displayed directly, the waveform is difficult to observe for the user. Therefore, the display mode switching unit 11 adjusts the scale interval value Z. Next, 3 methods will be described as a method of adjusting the scale interval value Z.
Fig. 10 is a view showing example 1 of the adjustment process of the scale interval value Z (step S230) shown in fig. 8. The 1 st method of adjusting the scale interval value Z is a method of performing mantissa processing. The display mode switching unit 11 calculates the number of digits a of the integer part of the scale interval value Z (step S251). The display mode switching unit 11 causes the display control unit 12 to display a digit of a +1 or more obtained by adding 1 to the calculated digit a via a combo box of dialog boxes (step S252). Fig. 11 is a diagram showing the digit selection screen 250 displayed in step S251 in fig. 10. The digit selection screen 250 is a dialog box including a combo box 251 for selecting the number of digits and an OK button 252 for making a determination on the selection. The number of bits above a +1 bit is displayed as an option in the combo box 251. The user selects the digit number b of a +1 digits or more using the combo box 251 of the dialog box (step S253). The display mode switching unit 11 performs mantissa processing on the b +1 th bit of the scale interval value Z using the selected value of the number of bits b (step S254). At this time, the display mode switching unit 11 causes the display control unit 12 to display the scale interval value Z' after the mantissa processing. Fig. 11 shows a state where b is 4 bits selected, and the 5 th bit is subjected to mantissa processing together with the integer part, and the scale interval value Z' after the mantissa processing is displayed as 33.33.
Fig. 12 is a diagram showing an example of a waveform display in the case where the scale interval value Z shown in fig. 10 is adjusted. In the example of fig. 12, the scale interval value Z is rounded to the 2 nd digit below the decimal point as the mantissa processing. If the difference between the upper limit Ymax 100 and the lower limit Ymin 0 divided by the number of divisions X3, the division interval Z becomes 33.3333 …, which is a value that cannot be completely divided. The scale interval value Z is rounded to a 2 nd digit below the decimal point, i.e., Z' is 33.33. In this case, 33.33, 66.66, and 99.99 are displayed as values corresponding to the scale. Here, the scale interval value Z is a number up to 2 nd digit below the decimal point, but is not limited to the example according to the present invention. The number of bits of the scale interval value and the method of processing the mantissa are not limited.
Fig. 13 is a view showing example 2 of the adjustment process of the scale interval value Z (step S230) shown in fig. 8. The 2 nd method of adjusting the scale interval value Z is a method of changing the upper limit value Ymax or the lower limit value Ymin so that the scale interval value Z is divided.
The display mode switching unit 11 calculates a remainder value Z' of the scale interval value Z (step S261). The relationship of remainder value Z ═ y max-Ymin)% X holds. When Ymax is 100, Ymin is 0, and X is 3, Z' is 1.
The display mode switching unit 11 determines whether or not to change the upper limit value (step S262). When the upper limit value is changed (Yes in step S262), Ymax ═ Y' max ═ 100-1 ═ 99 is assumed. When the upper limit value is not changed (No in step S262), the lower limit value Ymin is changed so that Ymin ═ Y' min ═ 0+1 ═ 1. After changing the upper limit value Ymax or the lower limit value Ymin, the display mode switching unit 11 recalculates the scale interval value Z (step S265). When the upper limit value Ymax is changed, Z is (Ymax-Ymin)/X is (99-0)/3 is 33, and when the lower limit value Ymin is changed, Z is (Ymax-Ymin)/X is (100-1)/3 is 33. Thus, the scale interval value Z is 33, which is a divided value.
Fig. 14 is a diagram showing an example of a waveform display in the case where the scale interval value Z shown in fig. 13 is adjusted. Fig. 14 shows a waveform displayed when it is determined that the display mode switching unit 11 has changed the upper limit value in step S262 in fig. 13. When the upper limit value Ymax is changed from 100 to 99, the scale interval value Z is 33, and 33, 66, and 99 are displayed as values corresponding to the scales.
Fig. 15 is a diagram showing example 3 of the adjustment process of the scale interval value Z (step S230) shown in fig. 8. The 3 rd method of adjusting the scale interval value Z is a method of changing the scale number X so that the scale interval value Z is divided. The display mode switching unit 11 changes the number of scales X (step S270). If the amplitude of the variation is set to a, X ═ X ± a. For example, when the scale number X is 3, Ymax is 100, and Ymin is 0, the scale interval value Z becomes a divided value if X is 2. When the scale number X is changed to 2, the display mode switching unit 11 recalculates the scale interval value Z (step S271). In this case, Z ═ (Ymax-Ymin)/X ═ 100/2 ═ 50.
Fig. 16 is a diagram showing an example of a waveform display in the case where the scale interval value Z shown in fig. 15 is adjusted. Fig. 16 shows a display example in the case where the scale number X is changed from 3 to 2. When the number of gradations X is changed to 2, the gradation interval value Z becomes 50, which becomes a divided value, and values corresponding to the gradations become 50 and 100. Here, an example in which the number of scales X is reduced from 3 to 2 is shown, but the present invention is not limited to this example. The number of graduations X may also be increased from 3 to 4 or 5. The scale interval value Z is 25 when the number of scales X is 4, and is 20 when the number of scales X is 5.
Next, switching of the display modes in the case where a plurality of waveforms are displayed on 1 screen will be described. Fig. 17 is a diagram showing a dialog screen 306 displayed when a display mode switching operation is performed on the waveform display screen 300 shown in fig. 7. If the switching of the display mode is performed using the switching combo box 305, the display mode switching unit 11 causes the display control unit 12 to display a dialog screen 306 for confirming whether or not to switch the display mode of all waveforms. The dialog screen 306 includes a 1 st button 307 for switching the display modes of all waveforms and a 2 nd button 308 for switching the display mode of the selected waveform.
Fig. 18 is a diagram showing a waveform display screen 310 displayed when the 1 st button 307 is selected on the dialog box screen 306 shown in fig. 17. When the 1 st button 307 is selected, the display mode in which the waveform is displayed in each of the display region M-1 and the display region M-2 is switched to the scale interval value designation display mode. In the display area M-1 of the waveform display screen 310, the waveform 301b is displayed in the scale interval value designation display mode. In the display area M-2 of the waveform display screen 310, the waveform 302b is displayed in the scale interval value designation display mode. In this way, the display mode switching unit 11 can collectively switch the display modes of the plurality of waveforms displayed by the display control unit 12.
Fig. 19 is a diagram showing a waveform display screen image 320 displayed when the 2 nd button 308 is selected on the dialog box screen image 306 shown in fig. 17. When the 2 nd button 308 is selected, the display mode of the waveform selected before the operation of switching the display mode is switched, and the display modes of the other waveforms are not switched. When the switching operation is performed in a state where the waveform 301a displayed in the display region M-1 is selected and the 2 nd button 308 is selected on the dialog screen 306, the waveform display screen 320 is displayed. In the display area M-1 of the waveform display screen 320, the waveform 301b is displayed in the scale interval value designation display mode. In the display area M-2 of the waveform display screen 320, the waveform 302a is still displayed in the upper and lower limit value designated display mode. As described above, when displaying a plurality of waveforms, the display control unit 12 can display the waveforms in a mixed manner in the upper and lower limit value designation display form and the scale interval value designation display form, and can display the waveforms in different display forms. The display mode switching unit 11 detects selection of a displayed waveform in accordance with an input operation, and switches the display mode of the selected waveform, thereby enabling individual switching of the mode of displaying a plurality of waveforms displayed by the display control unit 12.
As described above, the display control device 10 according to the present embodiment can use the upper and lower limit value designation display mode and the scale interval value designation display mode in a switchable manner. In the adjustment of the servo amplifier 30, many parameters need to be adjusted, such as whether the motor 40 is operating equally with respect to the command of the servo amplifier 30, how the motor 40 vibrates, and the like. In the parameter adjustment process, after the parameters are set, waveforms are acquired, analysis is performed while comparing a plurality of waveforms with each other, and resetting of the parameters, acquisition of the waveforms, and analysis are repeated a plurality of times. When comparing a plurality of waveforms, it is necessary to repeat the enlargement and reduction of the waveforms. In the case of performing enlargement and reduction of a waveform, in the upper and lower limit value designation display mode, it is necessary to calculate the ratio of enlargement or reduction, and it takes time and effort to calculate and designate the upper limit value and the lower limit value. In contrast, in the scale interval value designation display mode, since the scale interval value can be enlarged or reduced by directly inputting the scale interval value, the user's time and effort can be saved. When debugging a computer program for operating the controller 20, it is important to mainly check whether or not the program has operated according to a design book. To confirm that the program operates identically to the timing chart of the design book, a waveform display is used. Therefore, in many cases, the controller 20 is debugged to look at the entire waveform. In this case, the upper and lower limit value designation display mode may be set to input only a peak value to be seen, as compared with the scale interval value designation display mode, and thus, the user's time and effort can be saved.
The configurations described in the above embodiments are merely examples of the contents of the present invention, and may be combined with other known techniques, and a part of the configurations may be omitted or modified without departing from the scope of the present invention.
For example, in the above-described embodiment, the example of the display control device 10 that displays the input data from the positioning control system as a waveform has been described, but the present invention is not limited to the above-described example. The input data to the display control device 10 may be any input data that can be displayed as a waveform.
In the above-described embodiment, rounding was described as an example of mantissa processing, but the present invention is not limited to the above example. Examples of the mantissa treatment include a rounding-off treatment, a five-round super-five-round treatment, a five-round six-round treatment, and a four-round six-round treatment.
