Problems solved by technology

However, the USB Power Delivery chargers on the market are uneven, which will lead to device charging compatibility issues
Some chargers still exist. When the charger receives the hard reset signal, the serial bus voltage VBUS will not be powered off, causing the charging device to be disconnected and the communication process to be wrong.

Abstract

The invention provides a communication method based on universal serial bus power supply and a related device, and the method comprises the steps: firstly receiving a hard reset signal from charging equipment, so as to carry out initialization processing, and the initialization processing comprises pausing a power supply communication link with the charging equipment; then, adjusting the power supply voltage to a first voltage value in a first time period; then, when it is detected that the first voltage value is not adjusted to a second voltage value in a second time period, determining that the adapter is in a hard reset abnormal state, and the communication function of a first physical layer of the adapter is enabled; finally, sending a data packet to the charging device to reestablish the power supply communication link. According to the method of the invention, in the USB Power Delivery hard reset process, the communication function of the adapter and the charging equipment can be automatically enabled when an abnormal condition occurs, so that the process is prevented from being stuck, and the charging compatibility is improved.

Description

technical field [0001] The present application relates to the technical field of power supply communication, in particular to a communication method and related devices based on universal serial bus power supply. Background technique [0002] With the rapid popularization of USB Power Delivery technology, more and more charging devices begin to support USB Power Delivery charging technology. However, the USB Power Delivery chargers on the market are uneven, which will cause compatibility issues for charging devices. Some chargers still exist. When the charger receives a hard reset signal, the serial bus voltage VBUS will not be powered off, causing the charging device to be disconnected and the communication process to be wrong. Contents of the invention [0003] This application proposes a communication method based on universal serial bus power supply and related devices, which can automatically enable the communication function of the adapter and the charging device wh...
