Description

Description: TECHNICAL FIELD The present invention relates to an operation state display method during storage processing, and more specifically, it has a display means such as a CRT display and has a trigger function to perform storage processing. The present invention relates to a method of displaying an operating state during storage processing in a device such as a recorder or a waveform analyzer that can perform.

[Prior Art] In a device such as a recorder or a waveform analyzer having a trigger function, a processing method that does not accept a trigger until the pre-trigger data up to the trigger position is captured for the entire captured waveform data is adopted. .

For this reason, at the time of data acquisition operation, it must be in one of three states: the state in which data for the pre-trigger is being fetched, the state in which trigger detection is awaited, and the state in which data after trigger detection is being fetched. become.

FIG. 5 is a flow chart showing a conventional example of a processing procedure taken in relation to such various states.

That is, conventionally, when the storage process is started, the display means of the apparatus displays that the pre-trigger is awaited, and the pre-trigger data is stored while the pre-trigger data is fetched.

Next, it is displayed on the display means that it is waiting for a trigger, becomes a wait for trigger detection, and determines whether or not a trigger is detected. When a trigger is detected, the display on the display means is turned off, and then the trigger is detected. The storage process is performed while fetching the subsequent data, and the waveform is displayed on the display means based on the stored data.

FIG. 6 is an explanatory view schematically showing the display state of the display means corresponding to the above-mentioned three kinds of states at the time of the data fetching operation. In the pre-trigger wait state, the display means waits for the pre-trigger. A message indicating that there is a message indicating that there is a trigger is displayed in the state of waiting for a trigger, and a message disappearing from the display means when in the state of capturing data.

[Problems to be Solved by the Invention] According to the above-mentioned conventional method, since it is sufficient to display a change indication on the display means at the same time as changes in various operating states, the processing procedure for causing the control system to perform this is as follows. It was relatively easy to construct, and was favorable in that respect.

However, when the change speed of the state is slow, it is possible to easily read the other of the states from the display means, but as the change speed of the state becomes faster, the display pattern of each different one is replaced at high speed. As a result, the display flickers and becomes difficult to read, and not only the display message cannot be read, but also the display flickers, which may distract attention to the display of other parts. In addition, there were some inconveniences, such as a bad appearance.

[Means for Solving the Problems] The present invention has been made in view of the above problems found in the conventional method, and the structural feature thereof is that the pre-trigger components are controlled by the arithmetic control unit. Storage means for fetching data and data after trigger detection, operation state change determination means for generating an interrupt to determine a change in operation state in the storage means, and a message about the operation state after determination are displayed. In a device having a display means for
The difference between the above-mentioned state and the current state is determined through the determination means last time, and the message about the operation state is displayed through the display means only when the same operation state continues for a certain time or longer. To do.

Embodiments Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a functional block diagram showing an example of an operation state display function in a device to which the present invention is applied.

According to this, when the storage is started, the setting for generating the interrupt is made to the interrupt generating means 5 by, for example, generating at an interval of 16 msec, and the storage means 1, the trigger detecting means 2, and the storage means for the pre-trigger are stored. 3 through 3, it is possible to store each state in the RAM 4 for state storage.

On the other hand, the interrupt generated by the interrupt generation means 5 can be detected by the interrupt detection means 6, the processing state can be read from the RAM 4 by this interrupt, and the processing state change determination means 7 can determine the various states.

In addition, the operating state determined by the processing state change determination unit 7 is displayed on the CRT screen 10 by the message display unit 8.
Can be displayed on. Further, the storage means 3
The waveform data fetched by can be displayed on the CRT screen 10 through the waveform display means 9.

FIG. 2 is a flowchart showing the procedure of the storage process according to the present invention. While the storage process is being executed, (1) a state in which data for pre-trigger is fetched, (2) a trigger detection waiting state, (3) There are three types of operation states, that is, the data acquisition state after the trigger detection.

The variables used here indicate the following states, respectively.

“FLAG”… Indicates the previous status 0… Data acquisition status 1… Pre-trigger wait status 2… Trigger wait status “DISP”… Displayed message content 0… Clear (no display) 1… Pre-trigger wait 2… Trigger Waiting "COUNT" ... Counter indicating how many times the same state continues "STATE" ... Representing the current state 0 ... Data acquisition state 1 ... Pre-trigger waiting state 2 ... Trigger waiting state Now, according to the flowchart of FIG. In the storage process, in the first step, the variable “FLAG” is set to 0 to bring in the data, the variable “DISP” is set to 0 to make no display, and the variable “STATE” is set to 0. By doing so, the data acquisition state is set.

Then, for example, 16 msec is set to generate an interrupt at an appropriate constant interval, and the interrupt generation means 5
Generate an interrupt via. After that, the variable "STAT
By setting “E” to 1, the pre-trigger wait state is set and the storage process for fetching the pre-trigger data is performed.

After the storage processing of the data for the pre-trigger, the variable "STATE" is set to 2 to set the trigger waiting state, and the check for detecting the trigger is performed under the trigger waiting state. When a trigger is detected in this step, the variable “STATE” is set to 0 to enter the data acquisition state, and the data after the trigger detection is acquired.
Perform storage processing.

After the storage processing for fetching the data after the trigger detection is performed in this manner, the waveform is displayed on the CRT screen 10 or the like via the waveform display means 9 such as the CRT display. Thus, it is checked whether or not such a series of processing operations have been completed, and while the variable "STATE" is being changed in the same way, the waveform display of the acquired data is repeated. If the storage process is finished,
Processing for stopping the generation of interrupts is performed, and the display on the CRT screen 10 and the like is erased to return to the initial step.

FIG. 4 is a flowchart showing a procedure of interrupt processing when interrupts are generated at 16 msec intervals. In addition,
The interrupt generation interval can be set as appropriate as long as it is shorter than the time required to go around one of the three operating states.

According to the above flowchart, if the previous state (FLAG) and the current state (STATE) are different, a new variable "FLAG" is added.
And clear “COUNT”. At this time, if the message is already displayed on the CRT screen 10 etc.,
Erase the message and clear the variable "DISP".

If the previous state (FLAG) and the current state (STATE) are the same and the state is other than the data acquisition state (STATE = 1 or 2), add 1 to "COUNT" and set the value in advance. Then, it is checked whether or not it is a certain period of time, for example, whether or not "COUNT" is 6 or more.

If it is less than 6, the same state is 6 times 16msec, that is, 96ms
ec Do nothing because it has not continued, and if it is 6 or more, the same state continues for 96 msec or more, so C
A message to the effect that it is waiting for a pre-trigger or waiting for a trigger is displayed on the RT screen 10 or the like. The fixed time in this case is set to 96 msec as an example,
It can be appropriately set arbitrarily, and for example, it is preferably set to 100 msec.

The above interrupt processing will be described in more detail. When the interrupt processing starts, the variable "FLAG" representing the status one time before is the data acquisition status (0), the pre-trigger waiting status (1), or the trigger waiting status. It is determined whether or not (2).

If this is divided into cases and the case where it is determined that the pre-trigger waiting state (1) is determined in this determination step will be described first, in the next step, the variable "STA" representing the current state will be described.
It is determined whether "TE" is in the data acquisition state (0), the pretrigger waiting state (1), or the trigger waiting state (2). In this step, when it is determined that the state is still in the pre-trigger waiting state as in the previous time, 1 is added to the variable "COUNT" of the counter indicating the number of times the same state continues, and whether "COUNT" is 6 or more, for example. If it is less than 6, the same process is repeated until it becomes 6 or more. If it is 6 or more, the variable "DISP" indicating the content of the displayed message is waiting for a pre-trigger. If it is determined that it is not in the pre-trigger waiting state, a message indicating that the pre-trigger waiting state is set is displayed on the CRT screen 10 or the like, the variable "DISP" is set in the pre-trigger waiting state, and the process returns to the initial step. Also, in the determination step of the variable "STATE" representing the current state,
When it is determined that the data is in the data acquisition state, the variable “FLAG” representing the previous state is set to the data acquisition state (0).
Then, clear the variable "COUNT" of the counter that indicates how many times the same state continues, and in the next step, whether the variable "DISP" that indicates the content of the displayed message is clear (no display). When it is determined that there is a display, the message on the CRT screen 10 or the like is cleared, the variable "DISP" indicating the content of the displayed message is cleared (no display), and the process returns to the initial step. When it is determined in the step of determining the variable "STATE" indicating the current state that the state is waiting for the trigger, the variable "FLAG" indicating the state one time before is set as the trigger waiting state (2) and the same. Set the variable "COUNT" of the counter that indicates how many times the status has continued to 0 times, and in the next step, determine whether the variable "DISP" that indicates the content of the displayed message is clear (no display). If it is determined that there is a display, the message on the CRT screen 10 or the like is cleared, the variable "DISP" indicating the content of the displayed message is cleared (no display), and the process returns to the initial step.

On the other hand, when it is determined in the trigger waiting state (2) in the initial determination step of the variable “FLAG” that represents the state one time before, the pre-trigger is set in correspondence with the trigger waiting state. The processing is performed in the same manner as when the waiting state (1) is determined.

Further, when it is determined in the data acquisition state (0) in the initial determination step of the variable "FLAG" representing the state one time before, the variable "STATE" representing the current state is also obtained.
Is in the data acquisition state (0), the pretrigger waiting state (1), or the trigger waiting state (2). If the data acquisition state is still present, the process returns to the initial step and the pretrigger If it is in the waiting state, set "FLAG" to the pre-trigger waiting state, clear "COUNT", and then return to the initial step in the same manner. If it is in the trigger waiting state, set "FLAG" to the trigger waiting state and set "COUNT". After clearing, similarly return to the initial step.

Since the present invention is configured as described above,
A message indicating the operating state can be displayed on the CRT screen 10 or the like only when one operating state does not change even after waiting for a certain period of time, and one operating state changes before a certain period of time elapses. In case of CRT screen
It is possible to hide the message at 10 mag by turning off the message.

The display mode of such a message will be described in more detail with reference to FIG. 3, in which the variable "STATE" representing the current state is 1
When in the pre-trigger waiting state (1) like the variable “FLAG” which represents the previous state, no message is displayed on the CRT screen 10 etc. while “COUNT” is less than 6, Only when "COUNT" becomes 6 or more, a message indicating that the pre-trigger is waiting is displayed.

Also, when "STATE" is in the trigger waiting state like "FLAG", while "COUNT" is less than 6, no message is displayed on the CRT screen 10 etc. A message indicating that it is waiting is displayed.

Further, when "STATE" is in the data fetching state like "FLAG", "COUNT" is cleared to 0 so that no message is displayed on the CRT screen 10 or the like.

Therefore, a predetermined message is displayed on the CRT screen 10 or the like only when one operating state continues for a certain time, and the message display does not flicker.

In addition to the illustrated example, a desired pattern can be appropriately used as the message pattern displayed to indicate the operation state.

[Effects of the Invention] As described above, according to the present invention, the predetermined message is displayed only when one operating state continues for a certain period of time, so that the change of the operating state does not reach the certain period of time. The message is not displayed at all when changing at high speed, and the message is displayed when the operation state changes slowly over a certain period of time. Therefore, it is possible to eliminate the flicker of the message display on the CRT screen and the like. The badness can be wiped out.
