  However, the above-described conventional data collection apparatus has the following problems to be improved. That is, in the above data collection device, an alarm mark indicating that an alarm has occurred is displayed on a line segment indicating the sampling period in the calendar display unit, and the alarm occurrence time is displayed on the file integrated display unit. However, since the types of alarms (events such as dip, swell, and momentary power failure) are not displayed, in order to know the type of alarm, it is necessary to switch the display to waveform display and determine the type from the waveform. In this case, a configuration in which the type of alarm is displayed on the file integrated display unit is also conceivable. However, even if this configuration is adopted, what type of alarm occurred on which day, unless both the alarm mark display position and the type of alarm displayed on the file integrated display section are viewed It is difficult to confirm (intuitively) at a glance. Even when this configuration is adopted, when a large number of alarms are generated in a day, it is more difficult to confirm the type of alarm at a glance. As described above, in the conventional data collection device, it is difficult to easily check the date and type of alarm occurrence, and improvement of this point is desired.

  The present invention has been made in view of the problems to be improved, and provides a display device, a measurement device, a display method, and a program capable of easily confirming an occurrence date and type of an event that has occurred in a signal under measurement. The main purpose.

  Hereinafter, embodiments of a display device, a measurement device, a display method, and a program will be described with reference to the accompanying drawings.

  First, the configuration of the measuring apparatus 1 shown in FIG. 1 will be described. The measuring device 1 is an example of a measuring device, and stores waveform data Dw indicating the waveform of the input signal under measurement Sm (for example, the AC voltage shown in FIG. 2), and the amount under measurement of the signal under measurement Sm (for example, Voltage measurement), detection of events (examples of events) such as dip, swell, and instantaneous interruption, which are predetermined events for the measured amount of the signal Sm to be measured, and a measurement result image Gm by a display method described later. Processing such as display (see FIG. 6) can be executed. Specifically, as shown in FIG. 1, the measuring apparatus 1 includes a signal processing unit 11, an operation unit 12, a storage unit 13, a display unit 14, and a processing unit 15. In this case, the display unit is constituted by the display unit 14 and the processing unit 15.

  The signal processing unit 11 samples the signal under measurement Sm in synchronization with a sampling clock having a predetermined sampling period generated by a sampling clock generation circuit (not shown) according to the control of the processing unit 15 and outputs the signal under measurement Sm. Output processing for outputting waveform data Dw indicating a waveform is executed.

  The operation unit 12 includes various switches and outputs an operation signal when they are operated.

  The storage unit 13 stores a program (measurement program or display program (program)) of each process executed by the processing unit 15. The storage unit 13 stores the waveform data Dw output from the signal processing unit 11 according to the control of the processing unit 15. In addition, the storage unit 13 stores event data De (data indicating an event type, an occurrence time, and the like) generated by the processing unit 15.

  The display unit 14 displays various images such as the measurement result image Gm shown in FIG. 6 under the control of the processing unit 15.

  The processing unit 15 executes various processes according to the operation signal output from the operation unit 12 and the program stored in the storage unit 13. Specifically, the processing unit 15 executes a measurement process for measuring a measured amount (for example, a voltage value) of the measured signal Sm based on the waveform data Dw output from the signal processing unit 11. Further, the processing unit 15 functions as a detection unit, detects the occurrence of an event for the measured amount of the signal under measurement Sm, and generates event data De. Further, the processing unit 15 stores the waveform data Dw and event data De output from the signal processing unit 11 in the storage unit 13, and also records the waveform of the signal under measurement Sm based on the waveform data Dw and the event based on the event data De. A display process for displaying the measurement result image Gm including the detection result on the display unit 14 is executed.

  Next, a method for using the measuring apparatus 1 will be described.

  This measuring apparatus 1 is used, for example, when measuring a measured amount of a signal under test Sm (for example, AC voltage) shown in FIG. 2 for an arbitrary period (for example, several days to several months). When performing such measurement, the operation unit 12 is operated to start measurement. At this time, the operation unit 12 outputs an operation signal, the processing unit 15 reads the measurement program from the storage unit 13 according to the operation signal, and executes the measurement process according to the read measurement program. In this measurement process, the signal processing unit 11 is controlled to execute an output process of sampling the input signal under measurement Sm and outputting waveform data Dw indicating the waveform of the signal under measurement Sm. Next, the processing unit 15 stores the waveform data Dw output from the signal processing unit 11 in the storage unit 13.

  Further, the processing unit 15 measures a measured amount (voltage value) of the signal under measurement Sm based on the waveform data Dw, and from a change in the measured value, an event such as a dip, a swell, and a momentary interruption (such as a dip in the measured amount) Whether or not (event) has occurred is monitored, and when these events are detected, event data De including information on the type of event and the date and time of occurrence is generated and stored in the storage unit 13.

  In this case, the “dip” when the signal under test Sm is an alternating voltage is an event in which the voltage value as the amount to be measured drops for a short time t1, as shown in FIG. As shown in FIG. 5, the voltage value rises only for a short time t1, and “instantaneous power interruption” stops the signal under test Sm for a short time t1 as shown in FIG. Event.

  On the other hand, when displaying the measurement result of the measured amount in the measured signal Sm measured by the measuring apparatus 1, the operation unit 12 is operated to instruct the display of the measurement result image Gm. In the measurement apparatus 1, it is possible to instruct the measurement result image Gm even when the measurement process by the processing unit 15 is being performed or when the measurement process is completed (or stopped). ing.

  Subsequently, the processing unit 15 reads the display program from the storage unit 13 in accordance with the operation signal output from the operation unit 12, and executes display processing by the display method described below in accordance with the read display program. In this display process, as shown in FIG. 6, the processing unit 15 uses, as a measurement result image Gm, a calendar image C in which a plurality of daily areas A including the day on which the measurement process is performed are arranged in time series for each month. It is displayed on the display unit 14. In this case, the calendar image C is provided with a selection unit B for selecting “year” and “month”, and the operation of the operation unit 12 (for example, the surface of the display unit 14 facing the display location of the selection unit B). The “year” and “month” of the calendar image C can be selected by a touch operation on a part or a click operation on the selection unit B using a pointing device.

  Further, the processing unit 15 reads the event data De from the storage unit 13 and determines whether or not an event has occurred on the day corresponding to each region A in the calendar image C. At this time, if the processing unit 15 determines that an event has occurred, the processing unit 15 specifies the type of event and the date and time of occurrence. Next, as illustrated in FIG. 6, the processing unit 15 displays a mark (marker) that can specify the type of event in the area A corresponding to the day on which the event occurred. The mark displayed in the area A corresponds to “information indicating an event”.

  As an example, this measuring apparatus 1 employs a mark in which one alphabetic character representing the type of event is enclosed in a circle. Specifically, a mark in which “D” is surrounded by a circle (see FIG. 6: also referred to as “dip mark Md” in the following description) is adopted as a mark indicating a dip. Further, as a mark indicating a swell, a mark in which “S” is surrounded by a circle (see the same figure: also referred to as “swell mark Ms” in the following description) is adopted, and as a mark indicating an instantaneous stop, “I” is a circle. (See also the figure: also referred to as “instantaneous stop mark Mi” in the following description).

  Further, as shown in FIG. 6, the processing unit 15 sets the center of the mark at a position on the time axis corresponding to the time when the event occurs, with the horizontal direction (predetermined direction) in the region A as the time axis. To display the mark. In this measuring apparatus 1, as shown in the figure, a time axis Ta is used in which the left end of the region A is 0:00 am and the right end of the region A is 24:00 pm. Further, as shown in the figure, the processing unit 15 displays the mark by changing the display position for each type of event (mark) in the vertical direction of the region A (direction orthogonal to the time axis Ta).

  Here, when a large number of events occur on the same day, a large number of marks are displayed in one area A, and it may be difficult to determine the time of event occurrence and the type of event (mark). . For this reason, when the same type of event occurs more than the predetermined number of times (any number of 2 or more, 5 times as an example) on the same day, the processing unit 15, as shown in FIG. One mark whose number of occurrences can be specified is displayed in place of each mark individually corresponding to each event. In this measuring apparatus 1, as an example, a dip mark Md in which “D” and a number indicating the number of occurrences (for example, “6”) are surrounded by an ellipse is used as a mark indicating the occurrence of a plurality of dip. Further, as a mark indicating the occurrence of a plurality of swells, a swell mark Ms in which “S” and a number indicating the number of occurrences (for example, “5”) are surrounded by an ellipse is adopted, and a mark indicating the occurrence of a plurality of instantaneous interruptions As shown, an instantaneous stop mark Mi in which “I” and a number indicating the number of occurrences (for example, “5”) are enclosed by an ellipse is employed.

  In this case, when the processing unit 15 displays a mark indicating the occurrence of a plurality of events, for example, the processing unit 15 marks the position on the time axis Ta corresponding to the time when the first event occurred among the plurality of events. Position the left edge of By performing such display, it is possible to intuitively grasp at least the occurrence time of the first event.

  In the measuring apparatus 1, as described above, by displaying the mark corresponding to the generated event in the area A in the calendar image C, it is possible to know at a glance what kind of event has occurred on which day (intuitive). It is possible to confirm). In addition, since the mark corresponding to each event is displayed at a position on the time axis Ta corresponding to the time when the event occurred, it is possible to grasp the occurrence time of the event. In addition, in this measuring apparatus 1, when the same type of event occurs five times or more on the same day, one mark that can specify the number of times each event has occurred is displayed instead of each mark corresponding to each event individually. Therefore, it is possible to prevent a situation in which it is difficult to determine the time and type of the occurrence of an event because many marks are displayed in one area A.

  On the other hand, when it is confirmed that an event has occurred from a mark displayed on the calendar image C, it may be desired to grasp the detailed contents from the waveform of the signal under measurement Sm. In order to cope with such a usage pattern, the measuring apparatus 1 has a function of displaying the waveform of the signal under measurement Sm before and after the event occurrence time. When this function is used, an event for which a waveform is desired to be displayed as shown in FIG. 8 by an operation of the operation unit 12 (for example, a touch operation on the surface of the display unit 14 or an operation using a pointing device). Select the mark corresponding to.

  Subsequently, the processing unit 15 stores waveform data Dw for a predetermined time t2 (which can be specified at an arbitrary time, for example, 100 mS) including the occurrence time of the event corresponding to the selected mark. Read from unit 13. Next, as illustrated in FIG. 8, the processing unit 15 displays the waveform image Gw indicating the waveform for the time t2 based on the waveform data Dw so as to be superimposed on the calendar image C.

  Further, when displaying a waveform including the event occurrence time corresponding to one mark selected from the marks indicating the occurrence of multiple events, as shown in FIG. Select the mark that indicates the occurrence of the event. Subsequently, the processing unit 15 identifies the occurrence times of a plurality of events corresponding to the selected mark based on the event data De, and as shown in the figure, a list image showing the occurrence times of each event in a list Gt is displayed superimposed on the calendar image C. Next, as shown in FIG. 10, an event for which a waveform is desired to be displayed is selected by operating the operation unit 12 from among the events displayed as a list in the list image Gt. Subsequently, the processing unit 15 reads out the waveform data Dw for the time t2 including the occurrence time of the selected event, and as shown in the figure, the waveform image Gw showing the waveform for the time t2 based on the waveform data Dw. Is superimposed on the calendar image C and displayed.

  In the measuring apparatus 1, as described above, the event image is displayed by displaying the waveform image Gw indicating the waveform of the signal under test Sm for the time t2 including the event occurrence time corresponding to the mark only by selecting the mark. It is possible to quickly confirm the change in the voltage value of the signal under test Sm before and after the occurrence including the time when the occurrence of the occurrence of the occurrence of the error by an easy operation.

  As described above, according to the display device, the measuring device 1, the display method, and the program, by displaying the mark that can identify the type of the event in the area A corresponding to the day when the event occurs in the calendar image C, It is possible to easily confirm at a glance what kind of event has occurred on which day. Therefore, according to the display device, the measurement device 1, the display method, and the program, it is possible to easily determine whether the signal under test Sm is good or not based on, for example, the event occurrence timing and frequency.

  Further, according to the display device, the measuring device 1, the display method, and the program, by displaying a mark at a position on the time axis Ta corresponding to the time at which the event occurs, with the horizontal direction in the region A as the time axis Ta, It is possible to easily grasp at which time of the day an event has occurred.

  Further, according to the display device, the measuring device 1, the display method, and the program, by displaying the mark by changing the display position for each event type in the vertical direction in the area A (direction orthogonal to the time axis Ta). The type of event can be intuitively grasped from the display position in the vertical direction. In addition, by changing the display position in this way, when a plurality of types of events occur on the same day, it is possible to intuitively grasp that.

  Further, according to the display device, the measuring device 1, the display method, and the program, when the same type of event occurs five times or more (predetermined number of times) on the same day, each mark corresponding to each event is individually assigned. Instead, by displaying a single mark that can specify the number of occurrences of each event, a number of marks are displayed in one area A, making it difficult to determine the time and type of event occurrence. It is possible to reliably grasp the type and number of occurrences of an event while reliably preventing the occurrence of an event.

  In addition, according to the display device, the measuring device 1, the display method, and the program, when an operation for selecting a mark is performed in a state in which the mark is displayed, the time when the event for the selected mark occurs is included. By displaying the waveform image Gw showing the waveform of the signal under measurement Sm for a predetermined time t2, the change in the voltage value of the signal under measurement Sm before and after the occurrence including the time when the event occurred can be quickly and easily performed. Since it can be confirmed, the convenience when it is necessary to grasp the detailed contents of the event from the change of the voltage value can be sufficiently enhanced.

  In addition, a display apparatus, a measuring apparatus, a display method, and a program are not limited to said structure and method. For example, the form of each mark is not limited to the form described above, and can be arbitrarily changed. As an example, a mark whose color or shape is changed for each event type can be adopted. In addition, regarding the form of the mark indicating the occurrence of a plurality of events, the number of times may be changed to a form representing a number, and for example, a mark representing the number of times at the same number of points as the number of times may be employed.

  Further, although an example of detecting a dip, a swell, and an instantaneous interruption as an example of an event (event) has been described above, a configuration for detecting various other events (for example, transients and flickers) can be employed.

  Moreover, although it described above about the example applied to the measuring apparatus 1 which measures the voltage value as a to-be-measured amount in the alternating voltage as the to-be-measured signal Sm, the to-be-measured signal Sm and the to-be-measured amount are not limited to this, The present invention can be applied to a measuring apparatus that measures a measured amount of various measured signals Sm such as a voltage value of a voltage, a current value of an alternating current and a direct current, and a power value.
