Description

  The present invention relates to a message display device for a measuring apparatus that generates a new window in front of a window for displaying a measurement result and displays a message on a display screen. More specifically, the message display window is a maximum on the display screen. The present invention relates to a message display device for a measuring apparatus that allows a user to quickly and accurately recognize a message having a high priority even when only one message is displayed.

  The message display device displays a measurement result of the measurement device and a message from the measurement device. The measurement device is, for example, a waveform measurement device, a spectrum analyzer, a power meter, and the like, and the message is, for example, an error message, a message indicating the state of the device, or the like. The message display device is one provided integrally with the measurement device, a personal computer connected to the measurement device (a measurement device without a display screen, a remote-controlled measurement device, or the like) (for example, Patent Document 1). 2).

  FIG. 5 is a display example of a conventional message display device. In FIG. 5, a waveform of a measurement result is displayed in a result display window W1 on the display screen, and a message display window dialog box W2 is displayed in front of (in front of) this window W1.

  Usually, the message from the measuring device is important to notify the user of the measuring device. For this reason, the dialog box W2 is displayed in front of the other windows W1 in the display screen so that the user can surely recognize it.

  In the box W2, an “OK” button for notifying the message display device that the user has confirmed the message is provided. Then, unless the “OK” button or the like in the box W2 is clicked, other windows W1 displayed on the display screen cannot be operated / set. For example, while the box W2 is being displayed, the window W1 is not focused even if it is clicked with the mouse. Then, by clicking the “OK” button in the box W2, the box W2 is deleted, and other windows W1 can be operated.

FIG. 6 is a configuration example of a conventional message display device (integrated with a waveform measuring device).
In FIG. 6, the setting unit 10 is a keyboard, a mouse, an operation panel of a measuring device, or the like. The measurement unit 20 receives a signal under measurement and outputs measurement data of the signal under measurement, an analysis result, and the like. The communication unit 30 communicates with external devices (storage devices such as USB, other measurement devices via a network, personal computers, etc.) to exchange data.

  The event processing unit 40 receives event information output from the setting unit 10, the measurement unit 20, and the communication unit 30, selects a necessary event, and generates a message corresponding to each event.

  The display processing unit 50 includes a measurement result display unit 51, a message display unit 52, and a queue 53. The measurement result is input from the measurement unit 20 and a message is input from the event processing unit 40, and image data is generated.

  The measurement result display unit 51 generates image data based on the measurement result of the measurement unit 20 (for example, the window W1 in FIG. 5).

  The message display means 52 generates image data for displaying a message from the event processing unit 40 (for example, box W2 in FIG. 5). The queue 53 stores the message from the event processing unit 40 in a FIFO format.

  The display unit 60 displays the image data from the display processing unit 50 on a display screen (not shown). The setting unit 10, the measurement unit 20, the communication unit 30, the event processing unit 40, and the display processing unit 50 are connected to each other through a common bus.

The operation of such an apparatus will be described.
The setting unit 10 performs various settings according to user operations. For example, the range of the input circuit (not shown) of the measurement unit 20, the sampling rate of the AD converter (not shown), the setting of waveform analysis such as DSP or FPGA (not shown), the communication protocol of the communication unit 30 Etc., GUI setting of the display processing unit 50, etc. Each time the setting unit 10 performs an operation from the user, event information related to the setting (for example, validity of the setting operation, completion of the setting operation, error of operation error, warning, etc.) is sent to the event processing unit 40. Output.

  Further, the measurement unit 20 measures the waveform to be measured and converts it into measurement data according to the setting conditions from the setting unit 10, performs data processing / analysis of the measurement data as necessary, and stores the measurement data, analysis results, etc. (Not shown) or output to the measurement result display means 51 of the display processing unit 50. Then, the measurement unit 20 outputs event information related to measurement (for example, a state during measurement (during measurement, measurement end, etc.), an error occurring during measurement, a warning, etc.) to the event processing unit 40.

  The communication unit 30 communicates with an external device according to the setting conditions from the setting unit 10 to exchange data, and stores the data in a memory (not shown). Then, the communication unit 30 outputs event information related to communication (for example, a state during communication (communication, communication end, etc., an error, a warning, etc. generated during communication) to the event processing unit 40.

  On the other hand, the measurement result table means 51 reads measurement results such as measurement data, analysis results, and the like from the measurement unit 20 and memory (not shown), generates image data, and displays them on the display screen of the display unit 60.

  Further, the event processing unit 40 selects event information that needs to be notified to the user from the event information from the units 10 to 30, and a message corresponding to the selected event (for example, a hard disk capacity for storing measurement data) Is received, an event such as “disk capacity shortage” is generated and output to the message display means 52.

  Then, the message display means 52 displays this message on the display screen of the display unit 60 by the dialog box W2. When the next message is input from the event processing unit 40 while the box W2 is displayed, the message is stored in the queue 53.

  Further, when the “OK” button in the box W2 is clicked by the mouse operation of the setting unit 10, the message display unit 52 deletes the box W2. If the next message is stored in the queue 53, the message display means 52 newly generates a box W2 and displays the next message on the display screen.

  The operation of the message display means 52 will be described in detail with reference to FIG. FIG. 7 is a flowchart showing the operation of the message display means 52.

  When the waveform measuring device is activated, the message display means 52 performs a received message processing routine S10 and a user confirmation processing routine S11, and repeats each routine until the measuring device is turned off (S12, S10, S11).

The operations of the routines S10 and S11 will be described in detail.
In the received message processing routine S10, when a message is received (S10-1), it is confirmed whether another message is being displayed in the box W2 (S10-2). If it is being displayed, a newly received message is displayed. When the message is stored in the queue 43 (S10-3) and is not being displayed, the newly received message is displayed on the display screen in the box W2 (S10-4).

  When no message is received (S10-1), after storing in the queue 43 (S10-3), after displaying a new message (S10-4), the routine proceeds to the next routine S11.

  In the user confirmation processing routine S11, when the message is being displayed in the box W2 (S11-1), the user determines whether or not the “OK” button in the box W2 has been clicked by the setting unit 10 (S11-2). If the message is not being displayed (S11-1), or if the “OK” button is not clicked even if it is being displayed (S11-2), this routine S11 is terminated and the process proceeds to the next step S12.

  On the other hand, when the “OK” button is clicked (S11-2), the message display means 52 deletes the box W2. If another message is stored in the queue 43, the message in the queue 43 is displayed on the display screen in the box W2 (S11-3, S11-4). If no message is stored in the queue 43, a new message is displayed. The message display is terminated without displaying the correct box W2 (S11-3, S11-5). And when the process of step S11-4, S11-5 is complete | finished, it moves to the following step S12.

JP 2000-2222032 A JP 2006-285433 A

  The measuring apparatus does not display a plurality of dialog boxes W2 on the display screen, and displays only one at most. This is to ensure that the user recognizes the message.

  Further, the message from the event processing unit 40 is generated regardless of the user clicking the “OK” button. The event processing unit 40 selects event information from the units 10 to 30 and outputs the event information to the message display unit 52. However, even a variety of selected messages are included.

  Further, if there is an important message indicating that the waveform measuring apparatus itself has a very serious influence (for example, the data of the measurement result or analysis result cannot be stored, the apparatus itself fails), the mere measurement performed by the apparatus There are also minor ones that just notify the processing.

  However, since only one box W2 is displayed on the display screen, there is a problem that display of a message that is really important and has a very high priority is delayed.

  This will be specifically described with reference to FIG. For example, messages are generated in the event processing unit 40 in the order of “calculation failure” (priority: medium), “disk capacity shortage” (priority: high), “recording start” (priority: low), and display means. A description will be given by using an example input to 52.

  In FIG. 8, (a1) is a state in which no message is displayed on the display screen. Then, (a2) receives the “calculation failure” message, and since the message is not displayed on the display screen, the received “calculation failure” message is displayed.

  Subsequently, in (a3), “disk capacity shortage” is received, but before the user clicks the “OK” button, that is, the message “calculation failure” is being displayed, the received message “disk shortage” is queued. 43.

  Further, in (a4), “recording start” is received, but the user has not yet clicked the “OK” button, and the message “calculation failure” is being displayed. To store.

  Then, at (a5), the user clicks the “OK” button, is notified that the message “calculation failure” has been confirmed, and the message “disk capacity shortage” in the queue 43 is displayed.

  Further, at (a6), the user clicks the “OK” button, is notified that the message “insufficient disk capacity” has been confirmed, and the message “recording start” in the queue 43 is displayed.

  Finally, at (a7), the user clicks the “OK” button, and is notified that the message “recording start” has been confirmed. Since the queue 43 is empty, the box W2 is not displayed.

  As described above, in the states of (a3) and (a4), the message “insufficient disk capacity” having a higher priority than the message “calculation failure” has already been received and held, even though the message display means 52 has received it. The message “insufficient disk capacity” cannot be displayed and remains stored in the queue 43 until the user confirms the message “calculation failure” being displayed (clicks the “OK” button).

  That is, even when a very important high priority message is generated, there is a problem that the display of the message with such a high priority is delayed and the user's recognition is delayed.

  Note that each time the message display means 52 receives a new message, it is possible to overwrite the currently displayed message with a new message and always display only the latest message. This will be specifically described with reference to FIG.

  In FIG. 9, (b1) is a state in which no message is displayed on the display screen. Then, in (b2), the “calculation failure” message is received, and the received “calculation failure” message is displayed.

  In (b3), “insufficient disk capacity” is received, and the message “calculation failure” is overwritten with the newly received message “insufficient disk capacity” regardless of whether the user clicks the “OK” button.

  Further, in (b4), “recording start” is received, and the message “disk capacity shortage” is overwritten with the newly received message “recording start” regardless of whether the user clicks the “OK” button.

  In (b5), when the user clicks the “OK” button, the box W2 is deleted, and the box W2 is not displayed.

  As described above, in the states (b3) and (b4), the user clicks the “OK” button, that is, the message “calculation failure” and “disk capacity shortage” are discarded even though the user has not confirmed. As a result, there is a problem that the message “Insufficient disk capacity” is not recognized by the user.

  Therefore, an object of the present invention is to realize a message display device for a measuring device that allows a user to quickly and accurately recognize a message having a high priority even when only one message display window is displayed on the display screen at the maximum. There is to do.

The invention described in claim 1
In the message display device for the measuring device that generates a new window in front of the window that displays the measurement result and displays the message on the display screen,
Message storage means for storing the message;
Priority storage means for storing the priority for each type of message;
Comparison means for referring to the priority of the priority storage means and comparing the priority of the message currently displayed on the display screen with the priority of the newly input message;
A message display means for displaying a high priority message on a display screen based on the comparison result of the comparison means, and storing a low priority message in the message storage means ;
When a message displayed on the display screen is confirmed by a user, a setting unit is provided for erasing a window for displaying the message on the message display means,
In response to an instruction from the setting unit, when the message display means erases a window for displaying a message,
The comparison means compares the priority levels of a plurality of messages stored in the message storage means to search for a message with the highest priority, and if there are a plurality of messages with the highest priority, the latest message is selected from them. Search for
The message display means displays the message retrieved by the comparison means in a newly generated window.
The invention according to claim 2 is the invention according to claim 1,
It is used for a waveform measuring apparatus.

The present invention has the following effects.
When a new message is input, the comparing means compares the priority of the message being displayed with the priority of the newly input message. Then, the message display means displays a high priority message on the display screen based on the comparison result of the comparison means, and stores the low priority message in the message storage means, so that the message display window is displayed on the display screen. Even if only one message is displayed at the maximum, a message with a high priority can be recognized quickly and accurately by the user, and all messages can be recognized by the user without omission.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a block diagram showing an embodiment of the present invention. Here, the same components as those in FIG. In FIG. 1, a display processing unit 70 is provided instead of the display processing unit 50. In addition, a message buffer 80 and a priority memory 90 are newly provided. The message buffer 80 is a message storage unit and stores a message output from the event processing unit 40. The buffer 80 can store any number of messages. The priority memory 90 is a priority storage unit, and stores the priority for each type of message output from the event processing unit 40 as a priority table.

  The display processing unit 70 includes a measurement result display unit 71, a message display unit 72, and a comparison unit 73. The display processing unit 70 is connected to the buffer 80 and the memory 90, and receives a measurement result from the measurement unit 20 and a message from the event processing unit 40. Then, image data is generated and displayed on the display unit 60.

  The measurement result display means 71 generates image data based on the measurement result of the measurement unit 20 (for example, the window W1 in FIG. 5).

  The message display unit 72 generates image data for displaying a message from the event processing unit 40 (for example, box W2 in FIG. 5). Further, the buffer 80 and the memory 90 are mutually connected.

  The comparison unit 73 refers to the priority table in the priority memory 90 and compares the priority of messages. For example, the priority of a message currently displayed on the display screen of the display unit 60 is compared with the priority of a message newly input from the event processing unit 40, and the priority of each of a plurality of messages stored in the buffer 80 is compared. The comparison result is output to the message display means 72.

The operation of such an apparatus will be described.
Since the operations of the setting unit 10, the measurement unit 20, the communication unit 30, and the event processing unit 40 are the same as those of the apparatus shown in FIG. 6, the description thereof will be omitted, and the operations of the display processing unit 70, the buffer 80, and the memory 90 will be described in detail.

  The measurement result display means 71 reads measurement results such as measurement data, analysis results, etc. from the measurement unit 20 or memory (not shown), generates image data, and displays it on the display screen of the display unit 60 (for example, FIG. 5 window W1).

  Then, the message display means 72 displays the message from the event processing unit 40 on the display screen of the display unit 60 by the dialog box W2. When the next message is input from the event processing unit 40 while the box W2 is displayed, the comparison unit 73 compares the priority of the message currently displayed on the display screen with the priority of the newly input message. Further, the message display means 72 displays a message with a high priority on the display screen based on the comparison result of the comparison means 73, and stores the message with a low priority in the buffer 70.

  Further, when the “OK” button in the box W2 is clicked by the mouse operation of the setting unit 10, the setting unit 10 notifies the message display means 72 that the message has been confirmed by the user, and the message display means is in accordance with this notification. 72 deletes the box W2. Then, the comparison unit 73 searches for a message having the highest priority in the buffer 80. Further, the message display means 72 displays the message retrieved by the comparison means 73 on the display screen in the newly generated box W2.

  The operations of the message display means 72 and the comparison means 73 will be described in detail with reference to FIG. FIG. 2 is a flowchart showing the operation of the message display means 72 and the comparison means 73. Steps that are significantly different from the apparatus shown in FIG.

  When the waveform measuring apparatus is activated, the message display means 72 and the comparing means 73 perform a received message processing routine S20 and a user confirmation processing routine S21, and repeat each routine until the measuring apparatus is turned off (S22, S20, S21). ).

The operations of the routines S20 and S21 will be described in detail.
The reception message processing routine S20 will be described.
The message display means 72 determines whether or not a new message has been received from the event processing unit 40. If a new message has been received, the message display means 72 proceeds to a step of confirming whether another message is being displayed in the box W2 (S20). -1, S20-2), if not received, this routine S20 is ended, and the process proceeds to the user confirmation processing routine (S20-1, S21).

  In step (S20-2), the message display means 72 determines whether another message is already being displayed on the display screen of the display unit 60 by the box W2, and if it is not displayed, it is newly received. The message is displayed on the display screen in the dialog box W2 (S20-2, S20-3). If already displayed, the process proceeds to the next step of comparing the priority of the message (S20-2, S20-4).

  In step (S20-4), the comparison unit 73 reads the priority table from the priority memory 90, and compares the priority of the currently displayed message with the priority of the newly received message. Furthermore, when the message display means 72 refers to the comparison result and the priority of the newly received message is high, the newly received message is exchanged with the currently displayed message, and the newly received message is displayed in the box W2. And the displayed message is stored in the buffer 80 (S20-4, S20-5). On the other hand, when the priority of the newly received message with reference to the comparison result is low, the message display means 72 stores the newly received message in the buffer 80 (S20-4, S20-6).

  After displaying the received message (S20-3), after exchanging the message to be displayed (S20-5) and after storing the received message in the buffer 80 (S20-6), this routine S20 is terminated and the user confirmation process Move on to routine S21

Next, the operation of the user confirmation processing routine (S21) will be described.
The message display means 72 determines whether or not a message is already being displayed on the display screen of the display unit 60 by the box W2, and if it is not displayed, this routine is terminated and the routine proceeds to the next step (S21-1, S22). ), If it is being displayed, the process proceeds to the next step for determining the click of the “OK” button (S21-1, S21-2).

  In step (S21-2), if the message display means 72 has not received notification from the setting unit 10 that the “OK” button has been clicked, this routine ends and the process proceeds to the next step (S21-2). , S22), when the notification indicating that the “OK” button has been clicked is received from the setting unit 10, the message display unit 72 deletes the box W2 from the display screen and determines whether the message is stored in the buffer 80. (S21-2, S21-3).

  In step (S21-3), if no message is stored in the buffer 80, the message display means 73 ends the message display without displaying the new box W2, ends the routine, and The process proceeds to steps (S21-3, S21-4, S22).

  On the other hand, when a message is stored in the buffer 80 in step (S21-3), the comparison unit 73 reads the priority table from the priority memory 90, and prioritizes all messages stored in the buffer 80. Compare the degrees and search for the message with the highest priority. Then, the message display means 72 refers to the search result, reads the highest priority message, deletes the read message from the buffer 80, and displays the read message on the display screen in the newly generated box W2. S21-3, S21-5). After the display, this routine is terminated and the process proceeds to the next step (S21-5, S22).

  Then, it demonstrates using a specific example. FIG. 3 shows an example of a priority table in the priority memory 90. In FIG. 3, the higher the priority number, the higher the priority. FIG. 4 is a diagram showing a display example of the dialog box W2 and the state of the message buffer 80. As an example, messages are generated in the event processing unit 40 in the order of “calculation failure” (priority: 4), “disk capacity shortage” (priority: 5), “recording start” (priority: 3). An example of input to the display means 72 will be described.

  In FIG. 4, (c1) is a state in which no message is displayed on the display screen. In (c2), the display unit 72 receives the message “calculation failure”, but since the message is not displayed on the display screen, the display unit 72 displays the received message “calculation failure”.

  Subsequently, (c3) receives “disk capacity shortage”, the comparison means 73 refers to the priority table, and the priority of the currently displayed message “calculation failure” and the newly received message “disk capacity shortage” The message display means 72 stores “calculation failure” with low priority in the buffer 80, and displays the message “insufficient disk capacity” with high priority in the box W2 instead of the message “calculation failure”.

  Further, in (c4), “recording start” is received, and the comparison means 73 refers to the priority table again to determine the priority of the displayed message “disk capacity shortage” and the newly received message “recording start”. Compare. Since the priority of the newly received message “recording start” is low, the display means 72 stores the message “recording start” in the buffer 80, and the high priority message “insufficient disk capacity” continues to be displayed.

  In (c5), the user clicks the “OK” button, a notification that the message “insufficient disk capacity” has been confirmed by the user is sent to the display means 72, and the display means 72 erases the box W2. Then, the message to be displayed next is searched by the comparison means 73, and the message “calculation failure” having the highest priority in the buffer is displayed based on the search result.

  Further, in (c6), the user clicks the “OK” button, a notification that the message “calculation failure” has been confirmed by the user is sent to the display means 72, and the display means 72 deletes the box W2, Since the only remaining message is “recording start”, the message “recording start” is displayed.

  Finally, in (c7), the user clicks the “OK” button, and is notified that the message “recording start” has been confirmed. Since the buffer 80 is empty, the box W2 is not displayed.

  As described above, when the new message “insufficient disk capacity” is received while the message “calculation failure” is being displayed ((c2) in FIG. 4), the comparison unit 73 refers to the priority table of the memory 90. Compare priorities. Then, based on the comparison result, the message display means 72 displays the message “disk capacity shortage” with a high priority, and stores the message “calculation failure” with a low priority in the buffer 80 ((c3 in FIG. 4). )). As a result, even if the message occurred late in time, the message “Insufficient disk space” with a high priority is displayed on the display screen, and the message “Calculation failure” with a low priority is also buffered without being discarded. 80 and are displayed in order. Therefore, even when only one message display window W2 is displayed on the display screen at the maximum, it is possible to promptly and accurately recognize a message having a high priority, and to the user without leaking all messages. Can be recognized.

  Further, when the message “insufficient disk capacity” is being displayed ((c3) in FIG. 4), when the new message “recording start” is received, the comparison unit 73 refers to the priority table in the memory 90 to determine the priority. Compare. Based on the comparison result, the message display means 72 displays the high priority message “disk capacity shortage” as it is, and stores the low priority message “recording start” in the buffer 80 ((c4 in FIG. 4). )). As a result, as shown in FIG. 9, an important message is not overwritten by a low-priority message and is not recognized by the user, and the user can recognize a high-priority message quickly and accurately.

  Further, when the message display means 72 receives a notification that the “OK” button of the box W2 has been clicked from the setting unit 10 and the display means 72 deletes the box W2, the highest priority retrieved by the comparison means 73 is displayed. Since a high message is displayed ((c5) in FIG. 4), a message with a high priority can be displayed regardless of the temporal order of occurrence.

The present invention is not limited to this, and may be as shown below.
Although the configuration in which the message display device is integrated with the waveform measuring device is shown, it may be a device connected to the waveform measuring device via a network (wired, wireless LAN, Internet connection, etc.) and provided separately from the measuring device.

  Although the comparison means 73 showed the structure which searches the message with the highest priority from all the messages memorize | stored in the buffer 80 in step (S21-5), several messages of the same priority exist. In this case, the latest message (the latest message input from the event processing unit 40 to the message display unit 72) may be selected.

  The message type may be any message other than those illustrated in FIG.

  The dialog box W2 has a configuration in which only the “OK” button is shown. However, any type of button may be used. In addition to the button, information indicating the state of the apparatus, for example, a message being recorded in the memory is stored. You may display the time etc. which are required until completion.

  Although the configuration used for the waveform measuring device is shown as an example of the measuring device, it may be used for other measuring devices (spectrum analyzers, power meters, etc.), and is not limited to measuring devices, but also operates on personal computers, portable devices, etc. It may be used for utility software.
