Detailed Description
Other advantages and capabilities of the present invention will be readily apparent to those skilled in the art from the present disclosure by describing the embodiments of the present invention with specific embodiments thereof in conjunction with the accompanying drawings. The invention is capable of other and different embodiments and its several details are capable of modification in various other respects, all without departing from the spirit and scope 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, the present invention provides an interactive visualization apparatus for real-time test data, comprising: an electronic control board abstract figure generating unit 101, an initial information acquisition and output unit 102 and a test data updating unit 103.
The electric control board abstract drawing generation unit 101 is configured to generate a high-restoration electric control board abstract drawing according to the structure of the electric control board, mark pin names according to pin arrangement on the test box, and mark corresponding load names with the used pins. Preferably, each pin of the electrical control panel abstract diagram corresponds to an indicator light, and in 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, as shown in fig. 2.
And the initial information acquisition and output unit 102 is used for acquiring basic information of the test after the test is established and outputting the basic information in the abstract diagram of the electric control board. In an embodiment of the present invention, the basic information of the test includes: test name, test cartridge name, test start time, test end time, test status, and some or all of the notes. The test name, the test box name, the test starting time and the remark are obtained after the test is established and cannot be changed, and the test ending time and the test state are initial values obtained during the test establishment and need to be updated in real time during the test process.
The test data updating unit 103 obtains 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, in the test process, the pin data is changed in real time, the change of the pin data also causes the change of the test information, and in the test process, the change in the test basic information mainly includes the test state and the test end time. Specifically, each step of the test has an estimated running time at the time of test creation, the test data update unit 103 determines the current test state based on the change of the pin data and the estimated running time of each step, taking the electric control board of the washing machine as an example, when the signal variation of the corresponding pin corresponds to the pin signal variation of the "high speed washing" step, and the running time of the current step is approximately equal to the estimated running time, the current testing state is considered to be changed to the next step of 'high-speed washing', the testing ending time is updated according to the estimated running time of the rest steps, in the embodiment of the present invention, the test status is displayed in the format of "run to step < number > < step name >", and is updated in real time each time the next step is entered, as shown in fig. 3, when the test is completed, the update is displayed as "success/failure in step < number > < step name > < failure reason >".
Preferably, the test data updating unit 103 outputs the load value corresponding to each pin, i.e. the pin data, as required during the test process. In the testing process, because the value of each load changes in real time, the tester needs an intuitive way to know the critical load value at the current moment. As an embodiment, in this embodiment, when it is detected that the mouse is hovering to the corresponding pin, the test data updating unit 103 may highlight the information of the corresponding pin through the following hovering frame, where the pin information may include a load name and a load value corresponding to the pin.
Therefore, by generating the high-restoration electronic control panel abstract picture, the invention not only enables a user to generate visual perception on the appearance of the electronic control panel, the pins correspond to the physical panel, but also helps the user to perceive the real-time change of the data on the electronic control panel through the dynamically changed data and the bright/dark indicator lamps.

As shown in fig. 5a, taking an electric control board of a washing machine as an example, a shunt valve, a distributor and a flow meter are selected, all digital signals share a horizontal axis (time axis), a multi-graph linkage mode can be selected, and a user can compare the relationship among the signals conveniently, but each signal has a slider, and the user can move a region frame left and right or enlarge and reduce the selected region in a non-linkage state, so that the user can check the signal conditions in different time periods conveniently. And displaying corresponding pulse width on high/low level corresponding to the oscillogram, automatically measuring the period, frequency and duty ratio of each signal, obtaining a measured value if the signal is a periodic signal, and displaying only "- - -", and displaying accurate time (in millisecond unit) corresponding to a time point when the mouse is suspended. The user may also frame a time period, such as the interval of the rising edges of signal 1 and signal 2, and automatically display the length of the time period.
For the analog signal, since the analog signal is not overlapped by the digital signal seriously, it is displayed in the same coordinate system, such as the variation graph of the temperature sensor and the turbidity sensor in fig. 5 b.
Preferably, the interactive visualization apparatus for real-time test data of the present invention further comprises a test report generation unit 105, configured to automatically generate a test report according to the requirement specification of the test department for subsequent data analysis, and the like.
