Problems solved by technology

[0005] Many functions simulated by software are different from the actual functions of the motherboard or cannot be successfully simulated at all, which brings difficulties to the test and results in inaccurate test results; in addition, the speed of mobile phone replacement is getting faster and faster. The functions of the mobile phone are continuously enhanced, and the investment of mobile phone manufacturers in mobile phone testing is also increasing accordingly. This requires the existing mobile phone testing system to be able to comprehensively test the various functions of the mobile phone Flip, and to be able to convert the existing mobile phone Flip through simple changes. Some mobile phone test methods can be easily transplanted to new test items, thereby reducing test costs, which is of great significance for mobile phone manufacturers to improve production efficiency and maintain their own brand effects, but obviously, the existing mobile phone test methods cannot meet the requirements. this request

example 1

[0040] Example 1: User Interface Testing

[0041] The hardware required for this test includes Traveler, test computer and Y-cable. As long as the Traveler is connected to the test computer through the Y-cable, the test software can be used to complete the user interface test according to the prompts, including the display of the main and secondary screens of the mobile phone, buttons, Bluetooth, infrared rays, and the test of the charging indicator.

[0042] It should be noted that, compared with the prior art, the solution of the present invention differs mainly in the way of controlling the Flip of the mobile phone: in the prior art, the function of the motherboard is simulated by software to control the Flip of the mobile phone, while the present invention In the solution, the Flip of the mobile phone is directly controlled through the main board. As for how the mobile phone Flip executes the corresponding functions under the control of the mobile phone motherboard and ho...

[0043] Example 2: Camera Test

[0044] Camera tests usually include camera focus (Focus) test and dust spot (Blemish) test, which can fully and specifically test the performance of mobile phone cameras. The mobile phone Flip installed on the Traveler takes a specific picture under the control of the main board, and then sends the picture back to the test computer through the main board and Y-cable, and the test software in the test computer automatically completes the analysis of the picture, as shown in the analysis. The clarity and uniformity of the captured pictures, and whether there are bright or dark spots on the pictures, etc., can determine the performance of the camera.

[0045] Example Three: Audio Test

[0046] This test can test the sound pressure level (SPL, Sound Pressure Level) and distortion (THD, Total Harmonic Distortion) of the speaker of the mobile phone and other related functions. The hardware used includes: test computer, power supply, audio amplifier, microphone, general purpose interface bus (GPIB, General Purpose Interface Bus) card, sound card and shielding box. Among them, the power supply is usually a Keithley2306 power supply, and the audio amplifier is usually a clio audio amplifier. The GPIB card is installed on the test computer and connected to the Keithley2306 power supply through the GPIB cable. The sound card is also located on the test computer; the shielding box is used to seal the Traveler in its own space to shield the external noise interference.

[0047] The test software controls the Keithley2306 power supply through the GPIB card to provide 5V mobile phone power supply voltage and 3.7V audio circuit required...

Abstract

The invention discloses a method for testing a mobile phone, comprising the following steps: firstly, test software is installed in test computers of different test work stations in advance and when a certain function of a mobile phone Flip is tested, the mobile phone Flip is installed on a Traveler with a main board, and the Traveler is connected with the test computers of the test work stations; secondly, the test software of the test computers is opened according to a received operation command, and the test computers determine the model of the mobile phone to be tested and test items according to the received operation command and send a test command to the main board positioned on the Traveler according to a determination result; the main board controls the mobile phone Flip to execute corresponding functions according to the received test command; and finally the test computers acquire the execution result of the mobile phone Flip and analyze the execution result to obtain a test result. The invention simultaneously discloses a system for testing the mobile phone. The method and the system can conveniently and accurately realize the test for various functions of the mobile phone Flip.

Description

technical field [0001] The invention relates to testing technology, in particular to a mobile phone testing method and system. Background technique [0002] During the mobile phone assembly process, it is necessary to strictly test the functions of the mobile phone Flip (the mobile phone component that has been assembled without the motherboard and battery), such as user interface test (CIT, Customer Interface Test), audio (Audio) test and camera. test etc. [0003] At present, the existing test methods mainly use software to simulate various functions of the main board of the mobile phone for testing. Analyze the received sound to determine its performance, such as sound pressure level and distortion. [0004] However, there are certain problems in the actual application of the existing testing methods, such as: [0005] Many functions simulated by software are different from the actual functions of the motherboard or cannot be successfully simulated at all, which brings...
