Power distribution method, device and system of concentrator and storage medium

Abstract

The invention provides a power distribution method, device and system of a concentrator and a storage medium, the concentrator is connected to electronic equipment, the electronic equipment is connected to an adapter. The method comprises the following steps: obtaining the power of the adapter and the chip working power of the concentrator; detecting the working state of the downlink port of the concentrator to obtain the number of the downlink ports in at least one working mode; and obtaining the charging power of the electronic equipment according to the chip working power of the USBC concentrator, the number of the downlink ports of at least one working mode and the power of the adapter. According to the method, the device, the system and the storage medium provided by the invention, the corresponding working power is reserved according to different modes on the basis of detecting the working mode of the working downlink port of the concentrator, and then the residual power is updated and configured to charge the electronic equipment, so that the charging efficiency of the electronic equipment connected with the concentrator is maximized.

Description

technical field [0001] The present invention relates to the technical field of hubs, and more particularly relates to power distribution of hubs. Background technique [0002] More and more manufacturers of electronic equipment such as notebook computers and tablet computers, while pursuing the lightness and thinness of products, replace the original multiple types of ports with one or two types of ports. For example, a USB-C port, and by using a USB-C hub and similar products, this interface is extended to a charging port (PD charging protocol), a USB-A port, a different type of USB-C port, and so on. [0003] At present, when the USB-C hub is used as the expansion of the port of the electronic device, the input power of the PD adapter is generally obtained. According to the number of USB-A configured by the USB-C hub, the configuration of HDMI, and the configuration of SD / TF card, Configure fixed working power for these peripherals, and configure the remaining power to ch...

Problems solved by technology

However, it will cause waste of energy and unreasonable use, because the USB-A port, HDMI and other ports on the USB-C Hub may not be plugged in, or some ports may work, resulting in idle power of peripherals, causing computers or other electronic devices to lose power. Charging with a small power, the charging speed is slow, and the customer experience is poor
