Signal. The sound generating device 107, such as a buzzer, can also be a mobile phone for testing, which plays an audio file of a specific frequency in the sound shielding box 108 through a microphone attached to the mobile phone, such as 1KHz. The control terminal 1 makes the speaker of the mobile phone under test play the audio file just recorded through the ADB command. The motherboard of the mobile phone to be tested is recorded by a self-contained recording device, such as a Mic, and the recorded sound is played out in the sound shielding device 108 by the self-contained loudspeaker, and the sound collection device 112 on the test fixture assembly 3, such as a headset Return the audio information collection to the control terminal 1, and the automated test program running on the control terminal 1 will perform spectrum analysis on the collected audio files to determine whether the frequency is the corresponding 1KHz, if yes, the recording test has passed, otherwise The test failed. The test procedure of headphone loop test is similar to this.

Another embodiment of the present invention discloses a method for testing the functions of the mainboard of a mobile phone, which is implemented by the above-mentioned testing system for the functions of the mainboard of the mobile phone. As shown in Figure 3, it specifically includes the following steps:

Step 1. Prefabricate a standard image, and store the image information of the standard image in the storage module at the control end;

Step 2. The main board to be tested receives the control command from the control terminal, and displays the image through the display screen;

Step 3. The image testing device receives the control command from the control terminal, collects images from the display screen connected to the mainboard to be tested, and returns the image information displayed by the mainboard to be tested to the control terminal;

Step 4. The control terminal detects the main board of the mobile phone to be tested by comparing the image information of the standard image with the image information displayed by the main board to be tested.

The above step 1 is used to prepare for the test and collect standard images. On the basis of the above technical solution, step 1 also includes the following steps:

Step 11. A standard main board receives the control command from the control terminal, and performs image display through the display screen;

Step 12. The image testing device receives the control command from the control terminal, collects images from the display screen connected to the standard mainboard, and returns the image information displayed by the standard mainboard to the control terminal;

Step 13. The control terminal stores the image information displayed on the standard motherboard in the storage module of the control terminal to form the image information of the standard image;

Step 14. The control terminal sends multiple control commands for image display to the standard motherboard according to the preset settings, and repeats steps 11 to 13 until the preset times are completed.

Before collecting, the corresponding test settings can be made. For example, in the main control menu of the control terminal, enter the picture test through the corresponding setting options, and then perform corresponding settings. In an optional implementation, in the corresponding setting interface, a variety of different environmental settings can be selected, such as light brightness, light color, etc., and images can be collected multiple times in each environment to eliminate the impact of external environment changes. Image test device, such as testing the effect of the camera of the mobile phone when taking pictures.

In step 11 to step 14, the specific process of standard image acquisition can be that the control terminal makes the standard main board (that is, the mobile phone main board that has passed the test) refresh all the display screens connected to it to red through a control command, such as an ADB command, and then The camera of the test mobile phone is used to take pictures through the control command, and then the standard motherboard is used to refresh the display screen to green, and the camera of the test mobile phone is controlled to take pictures. In this way, the three pictures R1, G1, and B1 that can be collected can be saved locally. Testers check whether the three pictures are consistent with the actual display. If they are consistent, the acquisition is valid and can be saved as a standard image.

In step 14, the control terminal performs the next collection through the preset environment settings, such as changing the brightness of the external environment or the color of the light, and finally the tester judges whether the collected pictures are valid. Therefore, the preset settings here may include environment settings, test times settings, and the like.

On the basis of the above technical solution, step 4 also includes the following steps:

Step 41. The control terminal compares the color components of the image information displayed by the test board with the image information of the standard image at each pixel point; when the data difference of the color component of the corresponding pixel point is within the preset range, the control terminal determines the pixel point Similar, if it exceeds the preset range, it is judged not to be similar;

Step 42. When the ratio of the image information displayed by the test motherboard to all pixels of the standard image is greater than the preset threshold, the control end determines that the display image of the motherboard to be tested is similar to the standard image and the test is passed, otherwise it is determined not to be similar;

Step 43. When the image information displayed by the test mainboard is not similar to the standard image, the control terminal compares the image information displayed by the test mainboard with the image information of other standard images in the storage module of the control terminal according to step 41;

Step 44. When the image information displayed on the test mainboard is not similar to other standard image information in the storage module of the control terminal, the control terminal determines that the test fails; otherwise, the test passes.

The above-mentioned steps 2 to 44, the specific test and analysis process can be: make the display screen refresh to red, and control the image test device, such as testing the mobile phone camera to take pictures, and convert the pictures taken into a predetermined format, such as bmp format, according to the format Defines that the data in this file will be parsed and compared with the standard image. The method used for comparison is similarity, not complete equality. The so-called similarity means that the difference between the data of the color information components of each point of the photographed picture and the standard image is within a range, such as 5 or 10, and the two color components are considered The information is similar, and if it exceeds the range, it is considered not to be similar. In this way, the data of the two pictures can be counted, and finally a similar percentage can be obtained. If the similar percentage reaches 80%, it can be considered that the two pictures are the same, and the test can be continued. Otherwise, it will be the same as the red standard image collected twice. Comparing R2 and R3, if the similarity is lower than 80%, it is considered that the test fails, the test is exited, and a corresponding prompt is displayed on the control terminal. When comparing the color information components of each point above, an error range value and a similarity standard of 80% are empirical values obtained after a large number of tests. The smaller the error range value, the higher the similarity standard, and the higher the accuracy of the test, but the higher the requirements for the accuracy of the test mobile phone camera. In addition, by increasing the number of standard pictures, the compatibility of this test can be enhanced, especially when the camera effect is not good, the number of standard pictures collected needs to be increased. The same test process is used for the test when the display is refreshed to blue and green.

While the present invention completes the automated testing of the various functions of the mainboard of the mobile phone, it greatly improves the time period of the invention, the manpower cost invested and the versatility. Automated testing of multiple functions of the mobile phone motherboard. The test system development cycle is short, the practicability is high, and the cost is low.
