Abstract

A load power detection device based on a type-C interface and a detection method thereof are used for detecting a type-C interface, and the load power detection device based on the type-C interface comprises: a power supply module which provides a power supply for the type-C interface; a detection module which is used for detecting whether the type-C interface is connected with a pull-up resistor and a pull-down resistor or not; a control module which is used for controlling the type-C interface to output a voltage and a current; a load module which is connected with the output module, wherein the voltage and current output by the type-C interface are transmitted to the load module; a power detection module which detects the power of the load module; a judgment module which is used for judging whether the power detected by the power detection module is qualified or not and outputting a judgment result; and a display module which is connected with the judgment module, wherein the display module is used for displaying the judgment result of the judgment module. Therefore, whether the output power of the type-C interface is normal or not can be quickly detected, and the detection efficiency is greatly improved.

Description

【Technical field】 [0001] The invention relates to a connection interface power detection system and a detection method thereof, in particular to a type-C interface-based load power detection device and a detection method thereof. 【Background technique】 [0002] With the development of USB interface technology, the USB specification organization has announced a new type of USB interface, that is, the USB Type-C interface. The interface of this USB Type-C interface is divided into two rows, and each row has 12 signal pins. There are 4 VBUS pins, 4 GND pins, 4 pairs of TX / RX pins, 2 pairs of USBD+ / D- pins, 1 pair of SBU pins, and 2 CC pins. Because this new USB Type-C interface has the following characteristics compared with the old USB Type-A interface and USB Type-B interface: 1. The interface size is thinner and smaller; 2. The data transmission speed is faster; 3. The transmission power Stronger ability; 4. Support positive and negative insertion. Therefore, this new type...
