Interface testing device for notebook computer

Abstract

The embodiment of the invention discloses an interface testing device for a notebook computer. The interface testing device comprises a control module, and an HDMI interface testing module, a USB testing module and a Type-c function testing module which are connected with the control module; the test device can effectively test each interface of the notebook computer, does not need to use additional equipment, achieves the effect of saving material resources, receives test information of the HDMI interface test module, the USB test module and the Type-c function test module by utilizing the control module, and can play a role in visualizing a test result; the display effect of the external display does not need to be checked manually, subjective judgment on the display effect is avoided, the test coverage rate is increased, the test efficiency is high, the labor cost is low, and great benefits are brought to production and operation of enterprises.

Description

technical field [0001] The invention relates to the technical field of interface testing, in particular to an interface testing device for a notebook computer. Background technique [0002] In the current technology, notebook computer interfaces include types such as high-definition multimedia interfaces HDMI, USB, and Type-C. In the production of notebook computers, it is necessary to test the transmission effect of the interface of notebook computers, but the current testing methods have the following defects: [0003] 1. Because the working mode of the U disk is too coupled with the operating system, the test in this way is not stable enough, which may cause the system to freeze and affect the production capacity; 2. The life of the U disk is limited, and the writing speed of most U disks is too slow to be able to Evaluate the stability of the computer's USB interface under full load, and the high-end U disk is expensive (the read and write life is limited). [0004] 2....

AI Technical Summary

Problems solved by technology

[0003] 1. Because the working mode of the U disk is too coupled with the operating system, the test in this way is not stable enough, which may cause the system to freeze and affect the production capacity; 2. The life of the U disk is limited, and the writing speed of most U disks is too slow to be able to Evaluate the stability of the computer's USB interface under full load, and the high-end U disk is expensive (the read and write life is limited)

[0004] 2. The current test of the HDMI interface of the notebook computer is not rigorous enough, that is, to read the level of the HDMI signal line to judge whether it is normal. This is not a functional test in the true sense, and it has a greater risk of mistesting

[0005] 3. The test boards of the current laptop type-c interface are not powerful enough, such as not supporting USB3.1gen2 rate, not supporting DP function test, etc.
