Abstract

The invention relates to a USB Type-C interface rapid testing system and method, that system at least includes: a type-C signal input interface; a Type-C protocol mast controller; a USB2.0 module; a USB3.0 module; a Display Port Module; an Electronic load. The host computer controls an MCU to send a test command to the Type-C protocol main controller to control signals switch to different functions, and then the corresponding function modules are controlled to access the circuits, so as to realize the control of the Type- C integrity test. The forward and reverse switching modules are used tosimulate Type-C interface forward and backward insertion, control each module test Type-C interface, and then switch the interface to the reverse insertion mode through the positive and negative switching module to retest. Only one plug-in is required to implement fast Type-C testing, the test efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of USB Type-C interface testing, in particular to a USB Type-C interface rapid testing system and a testing method thereof. Background technique [0002] USB Type-C is a connection interface of USB interface. It mainly has three transmission functions, namely USB data, power supply / charging, and DisplayPort video. USB data is divided into USB2.0, USB3.0 and USB3.1 communication protocols . USB Type-C has at least the following characteristics: 1. High-speed data communication, the maximum transmission speed can reach 10Gbit / S, and can support USB2.0, USB3.0 and USB3.1 communication protocols; 2. Support Power Delivery charging protocol, the maximum support 20V / 5A power supply; 3. The USB Type-C interface contains four sets of differential signal lines, so it can support the Display Port transmission protocol; 4. Supports forward and reverse insertion, and the interface will automatically identify and switch...
