AI Technical Summary
In existing technologies, testing the reversible insertion of Type-C interfaces requires actual plugging and unplugging, resulting in wasted time and costs. Furthermore, it is impossible to test reversible insertion, charging protocols, and current and voltage parameters simultaneously at the same workstation.
Design a USB port testing system, including a communication interface module, an MCU central control module, a USB charging protocol testing module, a USB switching module, and a USB power supply voltage measurement module. It realizes positive or negative insertion sensing by controlling the CC1 or CC2 port on the plug and supports switching tests between USB 3.0 and USB 2.0 hardware paths.
It enables reversible insertion testing of the Type-C interface without actual plugging and unplugging, and can simultaneously check charging protocol and current and voltage parameters, reducing time and cost and improving testing efficiency.
