The present invention can also be implemented or applied through other different specific examples, and various details in this specification can also be modified and changed based on different viewpoints and applications without departing from the spirit of the present invention.

FIG. 1 is a system architecture diagram of an interactive visualization device for real-time test data according to the present invention. As shown in FIG. 1 , an interactive visualization device for real-time test data according to the present invention includes: an electronic control board abstract diagram generation unit 101 , an initial information acquisition and output unit 102 , and a test data update unit 103 .

Among them, the electric control board abstract diagram generation unit 101 is used to generate a highly restored electric control board abstract diagram according to the structure of the electric control board, and label the pin names according to the pin arrangement on the test box, and the used pins are labeled with the corresponding payload name. Preferably, each pin of the abstract diagram of the electric control board corresponds to an indicator light. During the test process, the indicator light corresponding to the input/output pin is controlled to light up by detecting the change of the pin signal, as shown in FIG. 2 .

The initial information acquisition and output unit 102 is used for acquiring the basic information of the test after the test creation is completed and outputting it in the abstract diagram of the electronic control board. In a specific embodiment of the present invention, the basic information of the test includes: test name, test box name, test start time, test end time, test status, and some or all of the remarks. Among them, the test name, test box name, test start time, and remarks are obtained after the test is created and will not change, while the test end time and test status are the initial values obtained when the test is created, and need to be updated in real time during the test.

The test data updating unit 103 acquires the data of each pin in real time during the test process, and updates the basic information of the test in real time according to the change of the pin data. Specifically, during the test, the pin data changes in real time, and the change of the pin data also causes the change of the test information. During the test, the main changes in the test basic information are the test status and the test end time. Specifically, each step of the test has an estimated running time when the test is created, and the test data update unit 103 determines the current test state according to the change of the pin data and the estimated running time of each step, and uses the power of the washing machine to determine the current test state. Take the control board as an example. For example, when the signal change of the corresponding pin matches the pin signal change of the "high-speed washing" step, and the running time of the current step is roughly equal to the estimated running time, it is considered that the current test state should change to the next One step is "high-speed washing", and the test end time is updated according to the estimated running time of the remaining steps. In the specific embodiment of the present invention, the test status is displayed in the format of "running to step <number> <step name>". The next step will be updated in real time, as shown in Figure 3. When the test is completed, the display will be updated as "Success/failure at step <number> <step name> <failure reason>".

Preferably, the test data updating unit 103 outputs the load value corresponding to each pin, that is, pin data, as required during the test process. In the process of testing, since the value of each load will change in real time, the tester needs an intuitive way to know the key load value at the current moment. As an implementation manner, in this embodiment, when it is detected that the mouse hovers over the corresponding pin, the test data updating unit 103 can highlight the information of the corresponding pin through the following floating frame, where the pin information may include The load name and load value corresponding to the pin.

It can be seen that, by generating an abstract diagram of the electric control board with high reduction, the present invention not only enables the user to have an intuitive perception on the appearance of the electric control board, but also the pins correspond to the physical board, and dynamically change data and bright/dark indicator lights. Help users perceive real-time changes in data on the electronic control board.

Preferably, as shown in FIG. 4 , an interactive visualization device for real-time test data of the present invention further includes a load change monitoring unit 104 for monitoring and outputting the load change corresponding to each pin during the test process. Preferably, the load variation monitoring unit 104 can also measure the parameters of the signal according to the output signal, for example, for digital signals, measure the parameters such as pulse width, period, frequency, duty cycle and the like of the signal. Specifically, there are two types of data to be tested: digital signals and analog signals. In the specific embodiment of the present invention, for digital signals, the monitoring unit 104 can output the changes of each load in the form of multi-picture linkage, and specifically, time series data can be used. The change of each load is displayed in the form of a line graph. For digital signals, you can refer to the display of the oscilloscope and use the waveform diagram to display. The digital signal only has a value of 0/1, so there will be more overlap in the display in the same coordinate system. , is not clear and intuitive. In order to make it clear and intuitive, the load change monitoring unit 104 provides the user to select the signal to be displayed, hide the signal that he does not care about, compare the selected signal, such as the time difference between the rising edge of the signal, and output the measured signal. pulse width, period, frequency, duty cycle and other parameters.

As shown in Figure 5a, taking the electric control panel of the washing machine as an example, select the water diverter valve, distributor, flowmeter, all digital signals share a horizontal axis (time axis), and the multi-image linkage mode can be selected to facilitate the user to compare the difference between the signals. However, each signal has its own slider. In the non-linked state, the user can move the area frame left and right or zoom in and out of the selected area, which is convenient for users to view the signal conditions in different time periods. The corresponding high/low level of the waveform graph displays the corresponding pulse width, and each signal automatically calculates its period, frequency, and duty cycle. If it is a periodic signal, the measured value can be obtained, otherwise only "----" is displayed. , which displays the exact time (in milliseconds) of the corresponding time point when the mouse is hovered. The user can also select a time period, such as the interval between the rising edges of signal 1 and signal 2, and the length of the time period is automatically displayed.

For the analog signal, since the analog signal does not have the serious overlap of the digital signal, it is displayed in the same coordinate system, such as the change diagram of the temperature sensor and the turbidity sensor in Figure 5b.

This tabular test report allows users to correspond to steps and corresponding inputs in the form. and output, corresponding constraints are convenient for locating steps and troubleshooting, and the current steps are displayed at the top, and the user can always correspond to the current steps, as shown in Figure 6.

FIG. 7 is a flow chart of the steps of an implementation method of an interactive visualization device for real-time test data according to the present invention. As shown in Figure 7, a method for realizing an interactive visualization device of real-time test data of the present invention includes the following steps:

Step 701 , generating a high-reduction abstraction diagram of the electric control board according to the structure of the electric control board, labeling the pin names according to the pin arrangement on the test box, and labeling the used pins with the corresponding load names. Preferably, each pin of the abstract diagram of the electric control board is also provided with an indicator light, and during the test process, the indicator light corresponding to the pin with input/output is controlled to be on by detecting the change of the pin signal.

In a specific embodiment of the present invention, the basic information of the test includes: test name, test box name, test start time, test end time, test status, and some or all of the remarks. Among them, the test name, test box name, test start time, and remarks are the information obtained after the test is created and will not change, and the test end time and test status are the initial values obtained when the test is created, and need to be updated in real time during the test.

Step 703: Acquire the data of each pin in real time during the test process, and update the basic information of the test in real time according to the change of the pin data. Specifically, during the test, the pin data changes in real time, and the change of the pin data also causes the change of the test information. During the test, the main changes in the test basic information are the test status and the test end time. Since each step of the test has an estimated running time when the test is created, in step 703, the current test status can be determined according to the change of the pin data and the estimated running time of each step. Take the electric control board of a washing machine as an example. For example, when the signal change of the corresponding pin matches the pin signal change of the "high-speed washing" step, and the running time of the current step is roughly equal to the estimated running time, the current test state is considered. To change to the next step "high-speed washing", and update the test end time according to the estimated running time of the remaining steps, in a specific embodiment of the present invention, the test status is displayed as "running to step <number> <step name>" The format will be updated in real time every time you enter the next step.

Preferably, the value of the load corresponding to each pin will be output as required during the test. In the process of testing, since the value of each load will change in real time, the tester needs an intuitive way to know the key load value at the current moment. As an implementation manner, in this embodiment, when it is detected that the mouse hovers over the corresponding pin, the information of the corresponding pin can be highlighted through the following floating frame, where the pin information includes the load name corresponding to the pin and load value.

Preferably, the implementation method of the interactive visualization device for real-time test data of the present invention further comprises the following steps:

Monitor the change of the load corresponding to each pin during the test and output it. Preferably, the parameters of the signal can also be calculated according to the output signal. For example, for digital signals, the pulse width, period, frequency, duty cycle, etc. of the signal can be calculated. parameter. Since there are two types of test data, digital signals and analog signals, in the specific embodiment of the present invention, for digital signals, the change of each load can be output by means of multi-graph linkage. For digital signals, you can refer to the display of the oscilloscope and use the waveform diagram to display. The digital signal only has a value of 0/1, so there will be more overlap in the display in the same coordinate system, which is not clear and intuitive. It is clear and intuitive, which can provide users to choose the signal to be displayed, hide the signal they don’t care about, compare the selected signal, such as the time difference between the rising edge of the signal, and output the pulse width, period, frequency, and duty cycle of the measured signal. and other parameters.

Preferably, the implementation method of the interactive visualization device for real-time test data of the present invention further comprises the following steps:

Specifically, the test report can be output in tabular form, each row corresponds to a step, and each step has corresponding inputs, constraints and corresponding outputs. This tabular test report allows users to correspond to steps and corresponding inputs in the form. And output, corresponding constraints are convenient for locating steps and troubleshooting, and the current steps are displayed at the top, and the user can always correspond to the current steps.

2. The real-time data of the electric control board: its output is also at the front of the page. When the tester enters the test details page, he can intuitively know the current data situation on the electric control board without querying in the chart;

3. When the tester needs a more detailed understanding of the specific data values, changes, relationships, etc. of the test, they need to understand through the diagrams/tables. The importance of the real-time electronic control board data should be equivalent to the diagrams/tables.

At the same time, using an expandable/collapsed floating frame to display basic information allows users to view and confirm the real-time status of the test at any time anywhere in the test details.
