  Hereinafter, modes for carrying out the invention will be described in detail, but the scope of the present invention is not limited to these modes.

  FIG. 1 shows a waveform display device 10 to which the present invention is applied. The waveform display device 10 includes a measurement sensor 11, a measurement unit 12, a CPU (central processing unit) 15, a touch panel 16, a storage memory 19, an external I / F (interface) unit 26, and an external recording device 27. Yes.

  The measurement sensor 11 is, for example, a temperature sensor, a current sensor, a voltage sensor, a measurement probe, or the like. The measurement sensors 11 are provided for the measurement channels. The waveform display device 10 may include a connector to which the measurement sensor 11 can be attached and detached. For example, the measurement unit 12 includes an amplifier 13 that amplifies the measurement value measured by the measurement sensor 11 to an appropriate level, and an analog that performs analog / digital conversion on the amplified measurement value and outputs measurement data to the CPU 15. A digital converter 14 is provided. The measurement sensor 11 and the measurement unit 12 are the same as known measurement apparatuses.

  The CPU 15 operates according to a program stored in the storage memory 19 and controls the operation of the waveform display device 10 in an integrated manner. The CPU 15 controls the operation of the measurement unit 12 to perform measurement, and operates as a waveform display processing unit 30, a determination area setting unit 31, a selection range determination unit 32, and a process execution unit 33, as will be described later.

  The touch panel 16 is a combination of a display screen 17 such as a liquid crystal panel capable of displaying an image and an operation unit 18 such as a touch pad capable of detecting a contact position on the display screen 17. In the touch panel 16, since the display screen 17 also serves as the operation unit 18, the operation unit 18 is also referred to as a display screen 17 below.

  The storage memory 19 is a rewritable nonvolatile memory, and as an example, is a semiconductor memory such as a flash memory or a hard disk. In this example, the storage memory 19 also serves as an operation storage unit 21, a measurement data storage unit 22, and a partial waveform storage unit 23. Note that separate memories may be used as the units 21 to 23, respectively. When the measurement data is temporarily stored for display, a volatile RAM (random access memory) may be used as the measurement data storage unit 22. The operation storage unit 21 stores an operation program for the CPU 15 and operation conditions. The measurement data storage unit 22 stores measurement data. The partial waveform storage unit 23 stores waveform data in a range to be stored.

  The external I / F unit 26 is an interface for connecting an external device. The external I / F unit 26 is, for example, a wireless or wired LAN (Local Area Network), a modem, a USB (Universal Serial Bus), Bluetooth (registered trademark), a printer connection interface, or the like.

  The external recording device 27 is used as an external recording medium such as a portable semiconductor memory such as a USB memory or an SD (SD) memory card, or an optical disk memory such as a CD (compact disc) -R (recordable) / RW (rewritable). An external storage medium writing / reading device for recording data or reading data from an external recording medium.

  Next, the operation of the waveform display device 10 will be described with reference to FIGS. FIG. 3 shows a flowchart showing the operation of the waveform display device 10, and FIGS. 2 and 4 to 10 show examples of display and operation of the touch panel 16.

  The CPU 15 of the waveform display device 10 (see FIG. 1) operates according to a program in the operation storage unit 21 when the power is turned on. The CPU 15 controls the measurement unit 12 to perform measurement, and acquires measurement data. The CPU 15 stores the acquired measurement data in the measurement data storage unit 22. This measuring operation is the same as that of the conventional measuring apparatus.

  Further, the CPU 15 operates as the waveform display processing means 30, reads the measurement data stored in the measurement data storage unit 22, and displays a waveform based on the measurement data on the display screen 17. The waveform display processing means 30 may display the waveform in real time during the measurement, or may display the waveform by a waveform display operation by the measurer (operator) after the measurement is completed. The waveform display processing means 30 displays the measurement data such as voltage along the time axis as a waveform, or calculates the impedance based on the voltage and current measurement data, and then displays the waveform along the time axis. Or When the waveform display apparatus 10 performs measurement by sequentially moving the measurement probe with a moving mechanism, the waveform display apparatus 10 may display a waveform with the measurement position as the horizontal axis. The vertical and horizontal axes for displaying the waveform, the type of graph, and the like are the same as the waveform display method of a known waveform display device, and differ depending on the measurement object and the type of measurement data. The waveform display scale and the data range to be displayed can be set as appropriate by operating the touch panel 16.

  FIG. 2 shows a display example of the touch panel 16 (display screen 17). In the figure, an example in which the waveform display processing means 30 displays the waveform display window 1 on a part of the display screen 17 and displays the waveform W1 of the signal voltage in the waveform display window 1 is shown. In addition, the waveform display processing means 30 displays, for example, a horizontal axis (time axis) scale line 4 a and a waveform display vertical axis (voltage axis) scale line 4 b in the waveform display window 1. . Moreover, the waveform display processing means 30 displays the operation setting operation window 9 at the right end of the display screen 17 as an example. In the figure, the display position of the selection window 3 described later is indicated by a broken line.

  When storing the arbitrary range of the waveform W1, the measurer touches the partial storage mode button 2 in the operation setting operation window 9 with a finger to operate the waveform display device 10 in the partial storage mode.

  When the partial save mode button 2 is touched, the CPU 15 operates in the partial save mode and executes the partial save process shown in the flowchart of FIG.

  In the partial storage process shown in the figure, first, the CPU 15 operates as the determination area setting means 31 (see FIG. 1) (determination area setting step S1). In the determination area setting step S1, the determination area setting means 31 sets the sliding part of the contact position on the display screen 17 (waveform display window 1) as the determination area. This is shown in FIG.

  A finger 90 in FIG. 4 schematically represents the finger of the measurer. The measurer touches (contacts) the start point (left end) of the range in which the waveform W1 is desired to be saved with the finger 90 and touches the display screen 17, and then touches the finger 90 as indicated by an open two-dot chain line arrow in FIG. Slide to the end point (right end) of the range you want to save and release your finger 90. Contrary to the figure, it may be slid from the right side to the left side.

  The determination area setting means 31 detects a slide part on the display screen 17 on which the finger 90 touches and slides, and uses this slide part as a determination area. However, since the area of the part in contact with the finger 90 is small, It is preferable to set the determination area in an area wider than the slide part. For example, as shown in the figure, the determination area setting means 31 has a predetermined margin (width of one square) formed by, for example, scale lines 4a and 4b above and below the slide portion of the finger 90 ( A region with a margin width is set as the determination region 5. In this case, a band-shaped determination area 5 for two squares centered on the slide part is set. The predetermined margin may be a plurality of squares, or a margin such as 5 to 20 mm may be set. The margin may be appropriately determined in consideration of the size of the display screen 17, the display size of the waveform display window 1, and the size of the finger 90. The square including the slide part of the finger 90 may be used as the determination area.

  Further, the determination area setting unit 31 may set the start point and the end point of the determination area 5 on the scale line 4a on the time axis. In this case, the determination area setting unit 31 starts the determination area 5 from the latest scale line 4 a including the first contact position of the finger 90, and determines the determination area from the latest scale line 4 a including the last contact position of the finger 90. 5 is ended.

  The determination area setting means 31 preferably displays the determination area 5 explicitly. For example, the determination area setting unit 31 displays the determination area 5 with a frame line or changes the color from the background color. The determination area setting means 31 preferably displays the determination area 5 in conjunction with the movement of the finger 90 so that the determination area 5 extends to the right side along with the movement of the finger 90 sliding to the right side.

  Returning to the flowchart of FIG. 3, when the determination area setting step S1 is completed, the CPU 15 operates as the selection range determining means 32, and in the display waveform number determination step S2, the display screen 17 (waveform display window 1). To determine whether multiple waveforms are displayed. Since only one waveform W1 is displayed in the example of FIG. 4, the selection range determining means 32 determines that a plurality of waveforms are not displayed, and proceeds to selection window display step S7.

  In the selection window display step S 7, the selection range determination means 32 displays the selection window 3 on the display screen 17.

FIG. 5 shows a display example of the selection window 3 when there is one display waveform. The selection window 3 is an operation window for performing a selection operation of which one of a plurality of waveforms is to be stored. When there is one waveform, it is not necessary to select a waveform. 32, in a state in which check (X or V) as previously initial value to CH (channel) 1 checkbox ₆₁ corresponding to the waveform W1, to display the checkbox ₆₁ only selected window 3. In the case the waveform of one (short for selection window displaying step S7) checking the display of the box ₆₁ may be omitted. The selection range determination unit 32 displays a save button 7 for performing a save operation and a cancel button 8 for performing a save process cancel operation on the selection window 3.

  When the number of waveforms is one, the check box selection operation (the waveform designation operation) is not performed, so the selection range determining means 32 proceeds to the partial selection step S8 of the flowchart of FIG. Select the range.

  In the example illustrated in FIG. 4, as the range of the waveform W1 corresponding to the determination region 5, the horizontal axis (time axis) range of the determination region 5 and the horizontal axis range of the waveform W1 are associated with each other. Since the determination region 5 is in the range of −25 μs to −5 μS, the selection range determining unit 32 selects the waveform W1 in the range of −25 μs to −5 μS. The selection range determination unit 32 may explicitly display the waveform W1 in the selected range by changing the color and line type of other portions of the waveform W1.

  Subsequently, the CPU 15 determines whether or not the save button 7 is touched (save operation determination step S9 in FIG. 3). When the save button 7 is touched, the CPU 15 operates as the process execution means 33 and executes a save process (an example of a predetermined process in the present invention) (process execution step S10). In the process execution step S 10, the process execution means 33 reads the measurement data of the waveform W 1 in the range selected in the partial selection step S 8 from the measurement data storage unit 22 and stores it in the partial waveform storage unit 23.

  When the cancel button 8 is touched in the storage operation determination step S9, the partial storage process is terminated. Further, for example, when the selection window 3 is not operated during a predetermined timeout period of 5 to 90 seconds, the partial storage process may be terminated. When setting the timeout period, the cancel button 8 may not be displayed.

  Thus, the partial storage process when one waveform is displayed on the display screen 17 is completed. The measurer can display the partial waveform stored in the partial waveform storage unit 23 on the display screen 17 at any time.

  Next, the partial storage process when a plurality of waveforms are displayed on the display screen 17 will be described.

  FIG. 6 shows an example in which a plurality of waveforms W 1 and W 2 are displayed in the waveform display window 1 of the display screen 17. This figure shows a state in which the determination region 5 has already been set by the slide operation of the measurer's finger 90.

  In this case, in the flowchart of FIG. 3, in the display waveform number determination step S2, the selection range determination means 32 determines that a plurality of waveforms are displayed, and proceeds to the determination area waveform determination step S3. In the determination area waveform determination step S3, the selection range determination unit 32 determines whether each waveform has a waveform in the determination area 5. As for the determination method, it is preferable that the selection range determination means 32 determine based on the ratio of the waveforms included in the determination region 5. The selection range determining means 32 calculates the ratio of the portion included in the determination area 5 with respect to the range of the determination area 5 for each waveform W1, W2, and determines the waveform included in the determination area 5 at a predetermined ratio or more. It is determined that it exists in the area 5. The predetermined ratio is predetermined such as 30 to 70%.

  In the example illustrated in FIG. 6, the waveform W <b> 1 is included in the determination region 5 in the time range corresponding to the determination region 5. For example, when the predetermined ratio is 50%, the selection range determining unit 32 determines that the waveform W1 is present in the determination area 5 because the waveform W1 is included in the determination area 5 at a predetermined ratio or more. In addition, the waveform W2 is a part of the range of −25 to −20 μs and a part of the range of −10 to −5 μs with respect to the time range (the range of −25 to −5 μs) of the determination area 5. 5 is included. Since the period of the determination region 5 is 20 μs and the period in which the waveform W2 is included is 10 μs in total, the waveform W2 is included in the determination region 5 by 50%. Accordingly, the selection range determination unit 32 determines that the waveform W2 exists in the determination region 5 because the waveform W2 is included in a predetermined ratio (50%) or more.

  In the example shown in FIG. 7, the waveform W <b> 3 is included in the determination region 5 in the range of −20 to −15 μs. Since the period of the determination region 5 is 20 μs and the period of the waveform W3 included in the determination region 5 is 5 μs, the waveform W3 is included in the determination region 5 by 25%. Accordingly, since the waveform W3 is not included in the determination area 5 by a predetermined ratio (50%) or more, the selection range determination unit 32 determines that the waveform W3 does not exist in the determination area 5. It is determined that the waveform W1 exists in the determination region 5 as in the example of FIG.

  Subsequently, the selection range determination unit 32 proceeds to the presence / absence determination step S4, and determines whether or not at least one waveform exists in the determination region 5. In the example of FIG. 6, two waveforms W1 and W2 exist in the determination region 5, and in the example of FIG. 7, one waveform W1 exists in the determination region 5, so in both cases the waveform Therefore, the selection range determining means 32 proceeds to the initial value setting step S5. In the initial value setting step S5, the selection range determining means 32 sets the initial value of the check box to ON for the waveform existing in the determination area 5. The initial value of the waveform that does not exist in the determination area 5 is set to off. In the example of FIG. 6, the initial values of both the waveforms W1 and W2 are turned on. In the example of FIG. 7, the initial value of the waveform W1 is turned on and the initial value of the waveform W3 is turned off.

  Subsequently, the process proceeds to the selection window display step S7, and the selection range determining means 32 displays the selection window 3 by putting a check mark in the check box previously turned on in the initial value setting step S6.

FIG. 8 shows a display example of the selection window 3 when the waveforms W1 and W2 exist in the determination area 5 as shown in FIG. As shown in the drawing, the check mark appears attached is in the check box ₆₁ of the CH1 corresponding to waveform W1, checkbox 6 ₂ CH2 corresponding to the waveform W2 is displayed attached. FIG. 9 shows a display example of the selection window 3 when only the waveform W1 exists in the determination region 5 as shown in FIG. Display In this case, as shown in the figure, is displayed a check mark is attached to the check box ₆₁ of the CH1 corresponding to waveform W1, is is not subjected checkbox 6 ₂ CH2 corresponding to the waveform W3 Is done.

The measurer touches the save button 7 as it is if the displayed check boxes 6 ₁ and 6 ₂ are selected (specified). The check boxes 6 ₁ and 6 ₂ can be turned on / off (the presence or absence of a check mark) when the measurer touches the check boxes 6 ₁ and 6 ₂ . For example, when the check boxes 6 ₁ and 6 ₂ with check marks are touched, the selection range determining means 32 deletes the check marks, and conversely, the check boxes 6 ₁ and 6 ₂ without check marks are touched. When checked, put a check mark. The touch position may be the position of the characters “CH1” and “CH2”.

The selection range determination means 32 selects a range corresponding to the waveform determination region 5 designated by the check boxes 6 ₁ and 6 ₂ in the partial selection step S8. For example, in the display example of FIG. 6, when both of the check boxes 6 ₁ and 6 ₂ are selected, the selection range determining unit 32 selects the waveform W1 in the range (−25 μs to −5 μs) corresponding to the determination region 5. While selecting a part, the part of the waveform W2 of the range corresponding to the determination area | region 5 is selected. Further, for example, in the display example of FIG. 7, when both of the check boxes 6 ₁ and 6 ₂ are selected, the selection range determination unit 32 displays the waveform in the range (−25 μs to −5 μs) corresponding to the determination region 5. While selecting the portion of W1, the portion of the waveform W2 in the range corresponding to the determination region 5 is selected. Further, for example, in the display example of FIG. 7, when only the check box ₆₁ is selected, the selection range determining means 32, the portion of the waveform W1 of the range (-25μs~-5μs) corresponding to the determined region 5 select. The portion of the waveform W2 in the range corresponding to the determination area 5 is not selected. Each time the check boxes 6 ₁ and 6 ₂ are turned on / off, the selection range determining means 32 clearly indicates which part of which waveform W1 or W2 is selected by changing the color or the like. Is preferably displayed.

  When the save button 7 is touched (save operation determination step S9), the processing execution means 33 reads the measurement data of the waveform portion selected in the partial selection step S8 from the measurement data storage unit 22 and saves the partial waveform. It preserve | saves at the memory | storage part 23 (process execution step S10).

  Next, a case where no waveform exists in the determination area 5 as shown in FIG. 10 will be described.

In this case, in the flowchart of FIG. 3, the process proceeds to the determination area setting step S1 to the presence / absence determination step S4. In the presence / absence determination step S4, it is determined that none of the waveforms W1 and W2 exist in the determination area 5. The process proceeds to initial value setting step S6. In the initial value setting step S6, the selection range determining means 32 sets the initial value of the check box to ON for all the displayed waveforms W1, W2. As a result, in the next selection window display step S7, as shown in FIG. 11, check marks are displayed in all the check boxes 6 ₁ and 6 ₂ of CH1 and 2 corresponding to the waveforms W1 and W2.

The measurer touches the save button 7 as it is when saving both partial waveforms of the waveforms W1 and W2. When saving either waveform, specify the waveform to be saved in the check boxes 6 ₁ and 6 ₂ . The selection range determining unit 32 selects a waveform portion corresponding to the designation of the check boxes 6 ₁ and 6 ₂ , and the process executing unit 33 stores it in the partial waveform storage unit 23.

  As described above, the waveform display device 10 of the present invention can directly specify the waveform portion to be stored by the sliding operation of the finger 90 on the display screen 17. In addition, when there are a plurality of waveforms, the selection window 3 is displayed in a state where a waveform existing in the determination region 5 is selected in advance, so that a waveform to be stored can be easily selected. Furthermore, when there are a plurality of waveforms, all the waveforms are selected by setting the determination region 5 so as not to be applied to any of the waveforms, so that it is possible to easily select the waveforms collectively. Further, by displaying a check box for selecting a waveform in the selection window 3, the measurer can arbitrarily select which waveform is to be stored.

  Although an example in which the partial waveform is stored in the partial waveform storage unit 23 in the partial storage process has been described, the partial waveform may be stored in an external recording medium attached to the external recording device 27. Moreover, although the example which preserve | saves a partial waveform was demonstrated as an example of the predetermined | prescribed process in this invention, it is not limited to this example, For example, the enlarged display process magnified and displayed on the display screen 17, a printing process, Various other processes such as an arithmetic process and an external output process for outputting from the external I / F unit 26 to an external device may be executed.

  Moreover, although the example of a display of two waveforms was shown as an example of a some waveform, there is no limitation in the number of waveforms to display, and three or more may be sufficient. The selection window 3 may be displayed by appropriately increasing or decreasing the number of check boxes corresponding to the number of waveforms.

  In addition, although the example in which the finger 90 is slid in the horizontal direction has been described, the finger 90 may be slid in an oblique direction or a vertical direction in accordance with the waveform shape.

  Moreover, although the example which attached the predetermined margin used at the time of setting the determination area | region 5 up and down was shown, you may make it attach on right and left. Further, as the partial storage mode button 2, the save button 7, and the cancel button 8, a push button type switch may be provided in the main body.

  Next, a program to which the present invention is applied will be described.

  FIG. 12 is a schematic diagram showing a usage state of the computer 50 operated by the program of the present invention. In addition, about the structure similar to the structure already demonstrated below, the same code | symbol is attached | subjected and detailed description is abbreviate | omitted.
