Description

Technical Field

[0001] The present invention relates to the technical field of television testing, and in particular to a television testing method, device, system and computer-readable storage medium. Background Art

[0002] Digital TV sensitivity is an important indicator of a TV. If a TV needs to meet the listing standards, it must comply with the standards of the corresponding TV. For example, a TV with DTMB (Digital Television Terrestrial Multimedia Broadcasting) TV function must meet the DTMB sensitivity standards.

[0003] In traditional testing, a standard signal generator can be used to provide signals of different frequency bands to the TV set, and the signal strength can be changed at different corresponding frequency points (including nearly 50 frequency points from 52.5MHz to 802MHz). When the signal strength is at the upper and lower limits, the TV channel screen cannot be displayed, there is no signal, the screen is distorted, and the TV audio is silent or the sound is intermittent. The upper and lower limits of the signal strength at this time are then recorded. When detecting each frequency point, take the DTMB digital TV function as an example, such as: requiring the TV signal strength range to be Min: ≤-82dBm; Max: ≥-10dBm. When the test shows that the TV screen at a certain frequency point within the signal strength range has the above abnormality, the signal strength does not meet the requirements, and the TV sensitivity is considered unqualified. Since traditional testing is to manually adjust the signal source output signal frequency and signal amplitude, and then the tester subjectively observes the picture and listens to whether the sound is normal, in order to obtain the test results, it is often necessary to repeatedly adjust the signal strength at the critical point, including switching the signal generator frequency band and TV signal source, which all take a lot of time. This testing method requires manual real-time operation and has low testing efficiency. Summary of the invention

[0004] The main purpose of the present invention is to provide a television test method, device, system and computer-readable storage medium, aiming to solve the problem of low test efficiency for television sensitivity test.

[0021] Importing the target sensitivity value into a preset test table, and comparing the target sensitivity value with the preset sensitivity value in the preset test table to obtain a comparison result;

[0022] If the comparison result is that the target sensitivity value is inconsistent with the preset sensitivity value, it is determined that the sensitivity of the frequency point to be tested is unqualified;

[0052] In this embodiment, the television test device composed of the above-mentioned standard signal generator, data acquisition device and core test device can realize automatic testing of television sensitivity, reduce labor costs, and improve test efficiency and accuracy.

[0053] Based on the above hardware structure, various embodiments of the method of the present invention are proposed.

[0054] Reference Figure 3 The present invention provides a television testing method. In a first embodiment of the television testing method of a television testing system, the television testing method comprises the following steps:

[0055] Step S10, sequentially setting a number of frequency points to be tested and the signal strengths corresponding to the frequency points to be tested according to a preset test table;

[0056] In this embodiment, the preset test table includes about 50 test frequencies from 52.5MHz to 802MHz arranged from low to high and the signal strength values ​​corresponding to the test frequencies, specifically including: 52.5MHz, 60.5MHz, 68.5MHz, 80MHz, 171MHz......794MHz, 802MHz and other frequencies. The signal strength value corresponds to the test frequency one by one, and can be set according to the standards required by technicians in this field. For example, if the signal strength needs to meet the national standard of 45dBm, the signal strength is set to less than 45dBm; or if the enterprise standard is 43dBm, the signal strength is set to less than 43dBm, so that the TV under test can search channels normally. The test control center is designed with a user interaction interface, including functions and interfaces such as test table import, test start, test stop, and test result export, and also includes a background corresponding configuration function, which can meet the background modification and input of test frequencies and standard values. Before executing step S10, a preset test form needs to be imported. The import of the preset test form can be done by importing an EXCEL table or by manual input. After completing the setting of the test requirements, the automated test of the system can be started by clicking the test start button.

[0057] In the implementation process of this embodiment, the TV test device needs to be started first, and the test control center establishes communication between the image and audio analysis module, the standard signal generator, and the TV to be tested. After the communication is established, the test control center retrieves the preset test table, and according to the frequency point sequence of the preset test table, the control core test device can sequentially set the frequency points to be tested for the standard signal generator through serial port communication according to the frequency points in the preset test table from low to high, so that the TV test device tests the frequency points to be tested in sequence.

[0058] Step S20, determining a target frequency point to be tested among the frequency points to be tested, controlling the TV under test to search for channels according to the target frequency point to be tested and the signal strength corresponding to the target frequency point to be tested, and obtaining a display screen of the TV under test.

[0059] In this embodiment, the target frequency to be tested is selected in the order of arrangement of the frequency to be tested in the preset test table, that is, from low to high. Of course, it can also be selected from high to low or from the middle to both ends, and the present invention is not limited again. After completing one target frequency to be tested, the remaining target frequency to be tested is selected in the preset test table until the test of all the frequencies in the preset test table is completed. Taking the target frequency to be tested as 52.5MHz and the signal strength corresponding to 52.5MHz as an example, since the TV under test can only search for channels within a suitable signal strength range and then display normally, the signal strength can be set to an intermediate reasonable value to avoid the signal strength being too high or too low, so that the TV under test cannot search for channels normally, and then obtain the display picture. Specifically, the serial port 2 between the test control center and the TV under test can be used to search for channels. Synchronously, the camera in the data acquisition device collects the image of the TV under test, and when the normal display picture is detected, the NORAML signal is fed back to the test control center, and the test control center determines that the search is completed.

[0060] Step S30, adjusting the signal strength, switching the display screen according to the adjusted signal strength, and determining the target sensitivity value corresponding to the frequency point to be tested according to the switched display screen;

[0061] The target sensitivity value is a range value, including a target upper sensitivity value and a target lower sensitivity value. The TV can display the image normally when it is within this range.

[0062] In one embodiment, the step S30 further includes:

[0063] Step A31, adjusting the signal strength, switching the state of the display screen to an abnormal state according to the adjusted signal strength, adjusting the signal strength again until the state of the display screen switches from the abnormal state to a normal state, and obtaining a target sensitivity value when the display screen is in the normal state;

[0064] In this embodiment, after the channel search is completed, the test control center changes the signal strength of the standard signal generator to change the display screen of the tested TV. The camera in the data acquisition device collects the display screen of the tested TV and transmits it to the image and audio analysis device. The image and audio analysis device compares the received display screen with the pre-stored standard display screen to analyze whether the screen is normal. When it is abnormal, the ERR signal is fed back to the test control center. After receiving the ERR mark, the test control center records the set level value of the standard signal generator corresponding to the signal strength at this time. This set level value can be recorded in the test control center so that the data can be directly called for fine-tuning in subsequent tests to improve the test efficiency. Then the test control center reversely adjusts the signal strength of the signal generator until the display state is normal, and records the signal strength value at this time, which is the sensitivity value of the frequency point. The test control center records the final sensitivity value as the sensitivity value of this frequency point.

[0065] Specifically, in one embodiment, the step A31 further includes:

[0066] Step A311, reducing the signal strength until the state of the display screen switches to an abnormal state;

[0067] In this embodiment, the signal strength can be reduced by lowering the level value in the standard signal generator, and because the display image of the tested television can only be displayed normally when it is within a specific signal strength range, the signal strength can be adjusted to make the television display image exceed this normal range, thereby switching the television display image to an abnormal state.

[0068] Step A312, increasing the signal strength until the state of the display screen switches from the abnormal state to the normal state, and using the increased signal strength as the target lower limit sensitivity value.

[0069] In this embodiment, since the channel search in the above embodiment can only search for display images that can be displayed, but the display images obtained by the channel search are not necessarily standard and normal, it is necessary to adjust the display images to an abnormal state and then to a normal state, so as to determine the minimum signal strength required when the display images are in a normal state, that is, the target lower limit sensitivity value. In this embodiment, specifically, the test control center uses serial communication to adjust the standard signal generator to change the level value of the standard signal generator, thereby adjusting the display image of the TV to switch the display state, and at the same time, the image and audio analysis device detects and analyzes the display image of the tested TV.

[0070] In one embodiment, the step A31 further includes:

[0071] Step A314, increasing the signal strength until the state of the display screen switches to an abnormal state;

[0072] Step A315, reducing the signal strength until the state of the display screen switches from the abnormal state to the normal state, and using the reduced signal strength as the target upper limit sensitivity value.

[0073] In this embodiment, since the sensitivity value corresponding to each frequency point is a range value, that is, there is a minimum sensitivity value and a maximum sensitivity value, when the TV under test is at this frequency point, it can only be played normally if the signal strength is between the minimum sensitivity value and the maximum sensitivity value, so it is also necessary to obtain the maximum sensitivity value, that is, the target upper limit sensitivity value. Specifically, first, the level value of the standard signal generator can be increased by the test control center using serial communication until the display screen obtained by searching the channel is switched to an abnormal state, and then the level value of the standard signal generator is reduced, and then the abnormal state of the TV screen is switched to a normal state, and the maximum signal strength that can be played normally on the TV corresponding to the frequency point is obtained, that is, the target upper limit sensitivity value. In the above manner, the present invention can accurately obtain the target sensitivity value corresponding to the frequency point to be tested, thereby improving the test accuracy.

[0074] It should be noted that when performing the upper limit sensitivity test and the lower limit sensitivity test, the order of the tests is random, that is, the upper limit sensitivity test can be performed first, and then the lower limit sensitivity test; or the lower limit sensitivity test can be performed first, and then the upper limit sensitivity test. The present invention does not make any restrictions here. After completing a sensitivity test of a frequency point to be tested, it can automatically determine whether another sensitivity test has been performed. If not, the next sensitivity test is automatically performed to achieve automatic switching of the target sensitivity test and improve the degree of automation of the test.

[0075] When conducting upper and lower sensitivity tests, it is also necessary to record the signal strength of the standard signal generator that is adjusted to the abnormal picture for the first time after searching the channel, and save the recorded signal strength so that the next time you adjust it, you can directly adjust the abnormal picture based on the recorded signal strength to improve test efficiency and accuracy.

[0076] Step S40, judging whether the sensitivity of the target frequency point to be tested is qualified according to the target sensitivity value and the preset test table, and obtaining the judgment result to complete the test.

[0077] The judgment results include unqualified and qualified. After completing one target frequency point to be tested, select the remaining target frequency points to be tested in the preset test table until the test of all frequency points in the preset test table is completed.

[0078] In one embodiment, the step S40 further includes:

[0079] Step A41, importing the target sensitivity value into a preset test table, and comparing the target sensitivity value with the preset sensitivity value in the preset test table to obtain a comparison result;

[0080] Step A42: if the comparison result is that the target sensitivity value is inconsistent with the preset sensitivity value, it is determined that the sensitivity of the frequency point to be tested is unqualified;

[0081] Step A43: If the comparison result is that the target sensitivity value is consistent with the preset sensitivity value, it is determined that the sensitivity of the frequency point to be tested is qualified.

[0082] In this embodiment, the preset test table also includes the original qualified sensitivity value corresponding to the frequency point to be tested, so it is necessary to compare the target sensitivity value obtained by the test with the original qualified sensitivity value, and then determine whether the original qualified sensitivity value is correct, and mark the unqualified value for subsequent judgment by subsequent testers. After completing the detection of a frequency point to be tested, continue to complete the detection of the next frequency point to be tested in sequence according to the preset test table until all the frequencies to be tested in the preset test table are completed. In order to further improve the accuracy and reduce the errors of automated testing, the tester can re-test and evaluate the unqualified values ​​according to the recorded results. Since only unqualified values ​​and questionable values ​​are retested, the test efficiency is greatly improved.

[0083] The present invention proposes a television testing method, which includes: setting a number of test frequencies and signal strengths corresponding to the test frequencies in sequence according to a preset test table; determining a target test frequency among the test frequencies, controlling the tested television to search for channels according to the target test frequency and the signal strength corresponding to the target test frequency, and obtaining a display screen of the tested television; adjusting the signal strength corresponding to the target test frequency, switching the display screen according to the adjusted signal strength, and determining the target sensitivity value corresponding to the test frequency according to the switched display screen; judging whether the sensitivity of the target test frequency is qualified according to the target sensitivity value and the preset test table, and obtaining the judgment result to complete the test. The present invention can realize that a set of television testing devices can complete the sensitivity test of a television through the above method, avoiding the situation in the prior art where only subjective judgment can be made by test personnel, improving test efficiency, and reducing labor costs. At the same time, since test personnel are prone to make errors in subjective judgment of test results, the above method and device of the present invention are used to test and judge the television using automatic frequency point testing and judgment, which can avoid the situation of making errors in judgment and improve the efficiency and accuracy of television sensitivity testing.
