Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In this application, relational terms such as first and second, and the like are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions, and the terms "comprises", "comprising", or any other variation thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
The present invention is applicable in numerous general purpose or special purpose test equipment environments or configurations. For example: personal computers, server computers, oscilloscopes, waveform display devices, test environments that include any of the above devices or equipment, and the like.
The embodiment of the invention provides a measurement channel selection method, which can be applied to a test process of channel parameters, wherein an execution main body of the method can be a processor of test equipment, and a method flow chart of the method is shown in fig. 1 and specifically comprises steps S101-S104. Wherein:
s101: when the trigger is detected to send a trigger signal to the test equipment, a target test channel corresponding to the trigger signal is determined, and a preset counter is started to count the trigger signal.
It will be appreciated that a trigger is an intermediary through which a user interacts with the test device, i.e. the user sends a trigger signal to the test device through the trigger. Specifically, the user sends a trigger signal of the target test channel to the test device through the trigger to trigger a test process of the test device on the target test channel.
In the embodiment of the present invention, the test device may include a counter, and after the test device receives the trigger signal of the target test channel, the counter arranged in the test device is started to count the trigger signal, so as to obtain a counting result of the trigger signal.
For example: the user sends a trigger signal to the test equipment through the trigger for the first time, the counter deployed in the test equipment counts the trigger signal to be 1, and when the user sends the trigger signal through the trigger item test equipment again, the counter deployed in the test equipment accumulates the trigger signal, namely 2. The trigger signals are counted in this manner.
It should be noted that the trigger may be disposed in the testing device and integrated with the testing device; or may be a separate trigger independent of the test equipment and not specifically described herein.
S102: and starting a preset timer to time, and acquiring the current count value in the counter when the timing time of the timer reaches the preset counting time.
It is understood that a preset timer is also one of the modules in the test device, and a counting time is set in the timer, that is, the corresponding set counting time in the counting process of the counter. And when the timing time of the timer reaches the counting time, ending the timing of the timer.
Specifically, after the test device receives the trigger signal, the test device starts the counter to perform a counting operation on the trigger signal, and starts the timer to perform a timing operation on a counting process of the counter, and determines a count value corresponding to the trigger signal by combining the counter and the timer. Namely, a preset timing duration is set in the timer, and when the timer reaches the preset timing duration, a count value corresponding to the trigger signal at the current moment of the counter is extracted.
For example: the user initiates a trigger signal to the test equipment for the first time through the trigger, after the test equipment receives the trigger signal, the test equipment starts the counter to count the trigger signal, the count value is 1, and simultaneously, the timer is started to time according to the preset counting time. If the user does not send the trigger signal to the test equipment any more in the timing process, the count value of the counter is 1; if the user initiates a trigger signal to the test equipment through the trigger again in the timing process, at the moment, the counter adds 1, namely 2, on the basis of the original count value; and when the timing is finished, extracting a count value corresponding to the trigger signal in the counter.
It should be noted that the count value of the counter may be other values, and is not specifically described here.
S103: and judging whether the count value is a preset test value or not, wherein the test value represents the trigger signal and is used for setting test parameters for a target waveform curve corresponding to the target test channel.
In the embodiment of the present invention, before the target waveform curve is set with each test parameter, it is determined whether the count value of the counter is a preset test value. It can be understood that there is a preset binding relationship between the test parameter setting process of the target waveform curve and a preset test value, the test value is a condition for setting the test parameter for the target waveform curve, and whether the target test channel meets the condition for setting the test parameter is determined by judging the count value.
It should be noted that each test parameter in the target waveform curve can be displayed in the test device only by configuring, and a target test channel of the test parameter needs to be configured in the configuration process of the test parameter, so that the test parameter can display the parameter of the target waveform curve.
S104: and if the count value is a test value, starting a target test channel corresponding to the trigger signal, and setting test parameters of a target waveform curve corresponding to the target test channel, wherein the test parameters are used for testing the target waveform curve.
In the embodiment of the present invention, a preset binding relationship exists between the test parameter setting process of the target waveform curve and a preset test value, that is, when the count value of the trigger signal corresponding to the target test channel is the preset test value, the test parameter setting of the target waveform curve is performed to indicate that the current target test channel needs to be bound with a channel item in the test parameter setting interface of the target waveform curve, and the target test channel is filled in the channel item in the test parameter setting interface of the target waveform curve, so as to complete the binding.
It should be noted that there may be a plurality of test parameters of the target waveform curve, and when the trigger signal count value corresponding to the target test channel is the preset test value, the channel items in the test parameter setting interface of all the target waveform curves are bound with the target test channel.
For example: the target waveform curve corresponds to 6 test parameters, namely P1-P6. Each test parameter corresponds to a channel entry to be filled in. And when the trigger signal count value corresponding to the target test channel is a preset test value, filling the target test channel into the channel items from P1 to P6 to complete the test parameter configuration of the target waveform curve.
According to the technical scheme, the invention provides a measuring channel selection method, which comprises the following steps: when detecting that the trigger sends a trigger signal to the test equipment, determining a target test channel corresponding to the trigger signal, and starting a counter to count the trigger signal; starting a preset timer to time, and acquiring a current count value in a counter when the timing time of the timer reaches a preset counting time; judging whether the counting value is a preset test value or not, wherein the test value represents a trigger signal and is used for setting test parameters for a target waveform curve corresponding to a target test channel; and if the count value is a test value, starting a target test channel corresponding to the trigger signal, and setting test parameters of a target waveform curve corresponding to the target test channel, wherein the test parameters are used for testing the target waveform curve. By applying the method, the process of setting the test parameters for the target waveform curve is realized through the trigger signal of the trigger, a technician does not need to click the menu bar and then select the test channel needing to set the test parameters from the menu bar, the time for setting the test parameters is saved, and the working efficiency of the technician is improved.
For the convenience of understanding of the above embodiments, the present application provides practical application processes of the above embodiments.
A user sends a trigger signal to test equipment through a trigger, after the test equipment receives the trigger signal, a counter is started to count the trigger signal, a timer is started to time the counting process, and when the timer finishes the timing function, the number of times of the trigger signal accumulated currently in the counter, namely the count value of the counter, is extracted; judging the counting value, and if the counting value is a preset test value, setting a target test channel as a channel item of each test parameter of the target waveform curve; if the count value is not the preset test value, the target test channel is selected, and experience functions such as display, target test channel moving and the like can be provided for the user.
In an example, in addition to the above-mentioned S101-S104, the measurement channel selection method provided by the present application may further include:
and if the count value is not the test value, starting a target test channel corresponding to the trigger signal, and displaying a menu bar corresponding to the target test channel.
It is understood that the count value is not the predetermined test value, and indicates that the count value extracted from the counter is not equal to the test value. For example: the count value is 1, etc. This case indicates that the user does not perform the setting of the test parameters of the target waveform curve. And in order to facilitate the experience of the user, when the counting value is not the test value, selecting the target test channel. Different experience functions can be set based on the selected target test channel, for example: when the trigger is a key module arranged on the test equipment, the function of displaying the target test channel is provided according to the selected target test channel; and when the trigger is an operation module connected with the external of the test equipment, providing a function of moving the target test channel for the user according to the selected target test channel. The user can have better test experience when using the test equipment to test the target test channel.
It is understood that different triggers are different from the triggers with which the user interacts, the types of the generated trigger signals are different, and the specific process for determining the target test channel corresponding to the trigger signal is also different. To this end, the present application provides two types of triggers for illustration.
In one example, referring to fig. 2, in step S101, a specific process when determining a target test channel corresponding to a trigger signal includes:
s201: the signal type of the trigger signal is determined.
Before determining the target test channel corresponding to the trigger signal, it is necessary to determine how the trigger signal is generated, and the embodiments of the present application describe in detail a generation process of the trigger signal.
The signal type of the trigger signal may include various implementations, for example: pressure trigger signals, operation instruction trigger signals, and the like.
S202: judging whether the trigger signal is a pressure trigger signal or not according to the signal type; the pressure trigger signal is a preset trigger signal sent by a pressure gauge, and the pressure gauge is arranged in the trigger.
S203: and if the trigger signal is a pressure trigger signal, determining that the trigger is a key module arranged on the test equipment.
It will be appreciated that the key module is a trigger for a built-in pressure gauge which generates a pressure trigger signal when a user presses the key module.
S204: and determining a key number corresponding to the key module, and determining a target test channel corresponding to the pressure trigger signal according to the key number.
It should be noted that the number of the key modules is the same as the number of the channels, and corresponds to one another. For example: the channel 1 corresponds to the key module 1, and after a user determines a target test channel to be tested, the user only needs to click the key module corresponding to the target test channel, and the key module generates a trigger signal to indicate the test equipment to complete a corresponding indication step. For example: indicating the test equipment to complete the setting process of the test parameters; or instruct the test equipment to complete the process of selecting the target test channel.
After the test equipment receives the pressure trigger signal, the step of setting the test parameters in the above embodiment is continuously completed.
In addition to the pressure trigger signals described above, the present application also provides non-pressure trigger signals, specifically as follows:
in one example, the specific process of determining the target test channel corresponding to the trigger signal includes:
and if the trigger signal is not the pressure trigger signal, determining the trigger as an operation module for carrying out external connection on the test equipment, wherein the operation module is used for clicking and selecting a waveform curve for carrying out test parameter setting on a display page of the test equipment.
It will be appreciated that the operational module is a device separate from the test device, for example: a mouse.
It should be noted that, a display page is further provided in the test equipment, and is used for displaying the waveform curves of the channels.
The user can select the waveform curve in the display page through the operation module, determine the selected target waveform curve and the target test channel corresponding to the target waveform curve, and based on the display page, when the user clicks the target waveform curve, an operation instruction trigger signal is generated and sent to the test equipment.
Determining a click area selected by an operation module on a display page, and judging whether the click area is in an effective area; the effective area comprises a plurality of waveform display sub-areas, and each waveform display sub-area is an area where the corresponding waveform curve is displayed on a display page.
And if the clicking area is in the effective area, determining a waveform display sub-area to which the clicking area belongs in the effective area.
It should be noted that the target waveform curve has a click region, and the click region includes any point of the target waveform curve on the display page, that is, the waveform display sub-region.
It is understood that the operation instruction trigger signal can be generated by clicking operation of the user at any point of the waveform display sub-region.
And determining a target test channel corresponding to the trigger signal based on the waveform display sub-region.
In the method provided by the implementation of the invention, the count value of the trigger signal extracted from the counter also indicates the end of the counting process of the trigger signal of the current target test channel. In order to avoid confusion with the next counting process of the target test channel trigger signal. The test equipment in the application also comprises a zero clearing module. The method comprises the following specific steps:
in one example, after obtaining the current count value in the counter, the method further includes:
and sending a count clear instruction to the counter so that the counter clears the count value when receiving the count clear instruction.
It will be appreciated that the count value in the counter is extracted, indicating that the counting process is complete. At the moment, the test equipment starts a zero clearing module to clear the count value in the counter. Specifically, after the count value is extracted from the counter, the test equipment starts a zero clearing module, and the zero clearing module generates a zero clearing instruction and sends the zero clearing instruction to the counter to instruct the counter to complete zero clearing of the count value.
