It is a flowchart which shows an example of the state display method to which this invention is applied.

  Hereinafter, although embodiment of this invention is described in detail, the scope of the present invention is not limited to these embodiment.

  A status display device 1 shown in FIG. 1 is a device in which a display 11, a mouse 12, and a keyboard 13 are connected to a control device 10, and monitors the status of equipment and displays the status.

  The control device 10 is a computer device such as a personal computer as an example, and includes a CPU (Central Processing Unit), a storage unit, a data input interface, a video card, an input / output interface, and the like. The control unit 10 operates by an operation program stored in the storage unit, and can perform various calculations. The control unit 10 can display an image on the display 11 connected to the video card. The control unit 10 can perform various input operations using the mouse 12 and the keyboard 13. Furthermore, the control unit 10 can store values input from the data input interface, values input from the keyboard 13, various calculation values, and the like in the storage unit.

  The data input interface of the control device 10 includes, for example, a voltage value or a current value output from a measuring instrument attached to various equipment to be monitored, and a high level when the equipment is normal and a low level when the equipment is faulty. Monitoring signals D1 to D6 (hereinafter simply referred to as monitoring signal D when not distinguished) such as failure detection signals to be output are input. The type and number of monitoring signals to be input are arbitrary. The data input interface may be configured to input an analog signal indicating a voltage value or the like as the monitoring signal D and perform analog / digital conversion using the data input interface, or to input digital data indicating the voltage value or the like as the monitoring signal. It may be. In the case of inputting digital data, the data input interface may be configured to input using a USB (Universal Serial Bus) or a LAN (Local Area Network).

  A setting value for determining whether the monitoring signals D1 to D6 are in a normal state or an abnormal state is stored in the storage unit of the control unit 10 in advance. The set value is set for each of the monitoring signals D1 to D6. As an example, the set value is input by displaying an input screen (not shown) for the controller 10 to input the set value on the screen of the display 11 and operating the keyboard 13 while watching the monitor. This is done by entering numerical values. For example, when the monitoring signal D1 is a voltage value, the set value is a value of 20V as a setting value for the monitoring signal D1 when the voltage value is 20V or less and is in a normal state and when it exceeds 20V, an abnormal state. And when this value is exceeded, an abnormal condition is set. Further, when the monitoring signal D6 is a logic signal and is at a high level when it is normal and at a low level when it is abnormal, it is set as an abnormal state when it is at a low level as a set value. The set value may be set in a numerical range that causes an abnormal state. Conversely, it can be set within a numerical range that is in a normal state.

  Such a control unit 10 operates as a determination unit, a display control unit, and a frequency measurement unit in the present invention in cooperation with a state display operation program stored in the storage unit. Further, the control unit 10 and the mouse 12 operate as confirmation input means in the present invention in cooperation with the operation program for status display stored in the storage unit.

  2 and 3 show an example of the monitoring window 21 displayed on the screen 20 of the display 11 by the display control means when the control unit 10 activates the operation program for displaying the state. In the monitoring window 21, state identification displays 22, 22... Indicating the states of CH1 to CH6 corresponding to the monitoring signals D1 to D6 are displayed. Further, the state identification display 22 is displayed in a circular shape as an example.

  FIG. 3 shows an example of the confirmation window 25 displayed on the screen 20 by the display control means. In the confirmation window 25, display columns of the CH number, occurrence date / time, confirmation date / time, and return date / time in which an abnormal state has occurred are displayed, and corresponding values are displayed. The confirmation window 25 is displayed on the screen 20 when the monitoring signal D is in an abnormal state. When the monitoring person operates the mouse 12 (see FIG. 1) and moves the mouse pointer 24 on the screen 20 to the confirmation window 25 and clicks the operation button of the mouse 12, the confirmation input means is in an abnormal state. It outputs to the display control means that a confirmation operation meaning that the monitor has confirmed the occurrence has been obtained. When there is a confirmation operation, the display control means may automatically delete the confirmation window 25 from the screen 20 or may automatically delete it from the screen 20 when the normal state is restored after the confirmation operation. The display may be continued until the operator performs an operation to close the window.

  FIG. 4 shows how the state identification display 22 and the numerical display 23 are displayed on the screen 20. 2 to 4, the state identification display 22 is assumed to be green for a circle-shaped display only, red for a hatched display, and orange for a display with a set of dots.

  In the control device 10, the determination means determines whether the values of the monitoring signals D1 to D6 input are normal or abnormal based on each set value set in advance in the storage unit, and performs display control. As shown in FIG. 4, when the means is determined to be in the normal state by the determining means, the first display is green as the first display, and when the means is determined to be in the abnormal state as the second display When a confirmation operation is obtained from the operation input means when the second color is red and the abnormal state is determined and displayed in red, the third color is displayed in orange as the third color. 22 is displayed on the screen 20. Further, in the control device 10, the number measuring unit measures the number of abnormal states that occur until the confirmation operation is obtained as the number of occurrences of abnormality. When the display control means returns to the normal state without obtaining the confirmation operation from the confirmation input means in the abnormal state, the numerical display 23 showing the number of occurrences of the abnormality measured by the number counting means together with the state identification display 22 is displayed on the screen. 20 is displayed. The display control means preferably deletes the numerical display 23 from the screen 20 when a confirmation operation is obtained from the confirmation input means in a state where the numerical display 23 is displayed on the screen 20 together with the state identification display 22.

  Hereinafter, the operation of the state display device 1 will be described in more detail with reference to the flowchart shown in FIG.

  When an operation program for state display is started to monitor the monitoring signals D1 to D6, the control unit 10 first performs initial setting (step 10; “step” is represented by “S” in the figure). With this initial setting, the control unit 10 displays the monitoring window 21 on the screen 20 (see FIG. 2). Moreover, the control part 10 resets the measured value of the frequency | count of abnormality occurrence of the frequency | count measurement means for every monitoring signal D1-D6 to 0.

  The control unit 10 executes the following operations for each of the monitoring signals D1 to D6. Since the operations for the monitoring signals D1 to D6 are the same, the operation of the control unit 10 for the monitoring signal D1 will be described. The description for D2 to D6 is omitted.

  In step 11, the control unit 10 determines whether or not the value of the monitoring signal D1 is in an abnormal state based on each set value set in the storage unit in advance.

  When it is determined in step 11 that the monitoring signal D1 is not in an abnormal state, that is, in a normal state, the control unit 10 proceeds to step 12 and uses the CH1 state identification display 22 as the first display as the first display. The color is displayed in green. This state is shown in FIG.

  Next, the control unit 10 determines in step 13 whether or not the measured value of the number of occurrences of abnormality is 1 or more. In this case, since it is 0, the process proceeds to step 19 until the monitoring signal D1 becomes an abnormal state. Continue monitoring.

  When an abnormal state occurs in step 19, the control unit 10 returns to step 11 and is determined to be in an abnormal state even in step 11, so the process proceeds to step 21 and the state identification display 22 is set as the second display. The second color is displayed in red. This state is shown in (2) of FIGS. As shown in FIG. 3, when an abnormal state occurs, the control unit 10 displays a confirmation window 25 on the screen 20.

  In the confirmation window 25 shown in FIG. 3, the number of CH1 and the date and time of occurrence of the abnormal state are displayed. The confirmation date / time and return date / time fields are blank because the confirmation operation and return have not been performed yet. The confirmation window 25 also displays the CH number, occurrence date / time, confirmation date / time, and return date / time for abnormal states that occurred in the past. For example, as shown in the figure, an abnormal condition has occurred in CH3 in the past, and the date and time of occurrence and the confirmation date and time are displayed. In this CH3, the date and time when the confirmation operation was performed is displayed in the confirmation date and time column, and the return column is blank because it has not been restored yet. In addition, the occurrence date / time, confirmation date / time, and return date / time when an abnormal condition has occurred in CH5 in the past are displayed in the corresponding columns.

  Returning to FIG. 5, the description will be continued. Next, the control unit 10 determines whether or not the number of occurrences of abnormality is 1 or more in step 22. In this case, since it is 0, the process proceeds to step 23. 1 is added to step S25, and it is determined in step 25 whether or not there is a confirmation operation.

  When there is no confirmation operation in Step 25, the control unit 10 repeats Step 25 and Step 26 until the confirmation operation is obtained or until it is determined in Step 26 that the monitoring signal D1 has returned to the normal state.

  If there is a confirmation operation in step 25, the control unit 10 proceeds to step 27, and displays the CH1 state identification display 22 in orange, which is the third color, as the third display. This state is shown in (3) of FIG.

  Next, the control unit 10 resets the number of abnormal occurrences to 0 in step 28, and continues monitoring until the monitoring signal D1 returns to a normal state in step 29.

  When it is determined in step 29 that the normal state has been reached, the control unit 10 returns to step 11 and proceeds to step 12 to display the state identification display 22 in green. This state is shown in (4) of FIG.

  Thus, since the status identification display 22 is green in the normal state, red in the abnormal state, and orange when the confirmation operation is performed, the monitor knows whether the monitoring signal is normal or abnormal. It is possible to confirm whether or not a confirmation operation has been performed. Further, when the numerical display 23 is not displayed, it can be confirmed that there is no omission of confirmation by the supervisor.

  On the other hand, when the normal state is restored in step 26 without confirmation operation in step 25, the control unit 10 returns to step 11 and proceeds to step 12 to display the state identification display 22 in green. Subsequently, the control unit 10 determines whether or not the number of occurrences of the abnormality is 1 or more at Step 13, and in this case, since it is 1, the process proceeds to Step 14 so that it overlaps the area of the state identification display 22. The number of occurrences of abnormality “1” is displayed as a numerical display 23. This state is shown in (5) of FIG.

  In this way, the number display 23 of “1” is superimposed on the green state identification display 22 so that the normal state has been restored at present, but the abnormal state that has not been confirmed has been 1 in the past. It can be seen that it has occurred.

  Returning to FIG. 5 and continuing the description, the control unit 10 repeats steps 15 and 16 until a confirmation operation is obtained in step 15 or until it is determined in step 16 that the monitoring signal D1 is in an abnormal state.

  When the controller 10 determines that an abnormal state has occurred in step 16, the controller 10 adds 1 to the number of occurrences of abnormality (step 17), returns to step 11, and proceeds to step 21 to display the state identification display 22 in red. To do. Subsequently, the control unit 10 determines whether or not the number of occurrences of the abnormality is 1 or more in step 22. In this case, since it is 2, the control unit 10 proceeds to step 24 and displays “1” displayed as the number display 23. Instead of “2” indicating the number of occurrences of abnormality, the state identification display 22 is displayed in an overlapping manner. This state is shown in (6) of FIG.

  In this way, the number display 23 of “2” is superimposed on the red state identification display 22 to return to the normal state without performing a confirmation operation in the past, and the current abnormal state is the second abnormal state. It turns out that it is in a state.

  Returning to FIG. 5, when the confirmation operation is obtained in step 25, the control unit 10 displays the state identification display 22 in orange in step 27 and resets the number of occurrences of abnormality to 0 in step 28. . By this reset, the control unit 10 turns off “2” in the numerical display 23. This state is shown in (7) of FIG.

  Subsequently, the control unit 10 proceeds to step 29 and continues monitoring until the monitoring signal D1 returns to the normal state. If it is determined in step 29 that the normal state has been restored, the process returns to step 11 and proceeds to step 12 where the state identification display 22 is displayed in green. This state is shown in (8) of FIG.

  On the other hand, when the number display 23 of “2” is displayed on the red state identification display 22 (in the case of (6) in FIG. 4), in step 25, the normal state is restored in step 26 without any confirmation operation. If it is determined, the process returns to step 11 and proceeds to step 12 where the state identification display 22 is displayed in green while the numeral “2” is displayed, and the process proceeds to steps 13 and 14. In this step 14 as well, the numerical display 23 remains unchanged and is displayed as “2”. This state is shown in (9) of FIG.

  In this way, by displaying the number display 23 of “2” superimposed on the green state identification display 22, the normal state has been restored at present, but the abnormal state that has not been confirmed has been detected in the past. It can be seen that it occurred twice.

  Returning to FIG. 5, the control unit 10 proceeds from step 14 to step 15, and when a confirmation operation is obtained in step 15, the abnormality occurrence count is reset to 0 in step 18. As a result, the control unit 10 erases “2” of the numerical display 23 displayed together with the state identification display 22 from the screen 20. This state is shown in (10) of FIG.

  The status display device 1 continues to operate as described above. When the confirmation operation is obtained in the state where the number display 23 of “1” is displayed on the green state identification display 22 shown in FIG. 4 (5), the control unit 10 turns off the number display 23. Further, when the numerical state 23 of “2” is displayed on the green state identification display 22 shown in (9) of FIG. 4 and the abnormal state and the normal state are repeated without obtaining the confirmation operation, The control unit 10 displays the numerical display 23 with “3”, “4”, “5”.

  By operating as described above, the supervisor can determine whether the monitoring signal D is normal, abnormal, or confirmed by viewing the state identification display 22. Furthermore, when there is an unconfirmed return that returns to the normal state without obtaining the confirmation operation in the abnormal state, the number of times that the abnormal state is obtained without obtaining the confirmation operation is displayed by the numerical display 23. By simply looking at the number display 23 at a glance, it is possible to quickly and surely know the number of occurrences of the abnormal state that has occurred so far without obtaining a confirmation operation. Therefore, in order to examine the number of occurrences of this abnormal state, it is not necessary for the monitor to count the number of occurrences of the abnormal state without the confirmation date displayed on the confirmation window 25, for example. Furthermore, since the numerical display 23 is not displayed when there is no unconfirmed return, the supervisor only needs to recognize that there has been an unconfirmed return when the numerical display 23 is displayed.

  In the confirmation window 25 (see FIG. 3), the confirmation date and time is displayed when a confirmation operation is performed, and the return date and time is described when the normal state is restored. Further, the confirmation window 25 returns to the normal state without obtaining confirmation operation, and when an abnormal state occurs, the CH1 number and the date and time of occurrence are written in a new line. In this way, when the normal state is restored without the confirmation operation, the confirmation date / time column becomes blank.

  In addition, although the example which erase | eliminated the numerical display 23 of abnormality occurrence from the screen 20 when confirmation operation was performed was demonstrated, you may erase | eliminate the numerical display 23 when it returns to a normal state after confirmation operation.

  In addition, although an example in which a numerical display of the number of occurrences of abnormality is superimposed in the area of the state identification display 22 has been shown, it is not in the area of the state identification display 22 but above, below, left, or right A numeric display may be displayed at a position such as. Moreover, although the example which displayed the state identification display 22 with the circular shape was shown, you may display the shape, such as a square shape and a star shape, in a desired shape. Also, as the first to third displays, an example is shown in which all are displayed in the same shape (circular shape), but the first display is circular, the second display is quadrangular, and the third display is triangular. You may change and display a shape like a shape. Thus, when changing the shape of the 1st-3rd display, it is more preferable to display by changing a color, since it is excellent in visibility, However, You may display a color by the same color as needed. The first to third colors are not limited to green, red, and orange, and may be displayed in other desired colors such as blue and yellow.

  In addition, as an example of the confirmation input means, the confirmation operation is obtained when the confirmation window 25 displayed on the screen 20 with the mouse 12 is clicked. For example, the state identification display 22 is clicked with the mouse 12. Confirmation operation may be obtained at the time of confirmation, or confirmation operation may be obtained by key operation of the keyboard 13. Alternatively, the display 11 may be replaced with a touch panel so that the confirmation operation can be obtained when the confirmation window 23 is touched.
