Embodiment Construction

[0042] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0043] Such as Figure 1-9 As shown, the specific embodiment of the present invention is a single-line multi-device priority communication method, including a master-end power supply device, the master-end power supply device can be electrically connected to one or more slave-end devices, and the master-end power supply device can be charged at the voltage V 1 , communication voltage V 2 To switch between, the master power supply device can detect the level V of the slave device a , the specific communication control method is as follows:

[0044] The first step is to divide the stage level, and divide a voltage level into N step levels V x , each step level corresponds to a slave device or corresponds to a state of the slave device;

[0045] The second step is power supply. When the slave device is connected, the master power su...

Abstract

The invention discloses a single-line multi-device priority communication method and system, and the method comprises the steps: a voltage level is divided into N step levels Vx, and each step level corresponds to one slave device or one state of the corresponding slave device; when the slave end equipment is connected, the master end power supply equipment is switched to V1 to supply power to theslave end equipment in a reset manner; when Va is equal to a certain step level Vx, the main end power supply equipment is switched to a communication voltage V2, and the main end power supply equipment sends main end electric quantity information and a communication instruction to the slave end equipment; and the main-end power supply equipment is switched back to the charging voltage V1, the level of the slave-end equipment is continuously detected, when Va is equal to the next step level Vx, the main-end power supply equipment sends main-end electric quantity information and a communication instruction to the slave-end equipment again, and circulation is repeated until Va reaches the full-charge voltage Vmax. According to the invention, the level step is used as state detection, resetting, charging or a certain state identifier is realized, communication is realized according to the level change time sequence (logic), and the problem of compatibility of communication and charging can be solved with low cost.

Description

technical field [0001] The invention relates to the field of intelligent wireless devices, in particular to a single-line multi-device priority communication method and system. Background technique [0002] With the rapid development of 3G, 4G, and 5G mobile communication devices, the matching smart wireless wearable devices are becoming more and more popular in the market, such as: Bluetooth headsets, TWS headsets, smart bracelets, smart remote controls, smart handles, Motion game controllers and more. [0003] Take Bluetooth headsets as an example, especially TWS (true wireless stereo) Bluetooth headsets, because they are so small that they can be worn directly in the ear, the battery can only choose a very small size, resulting in limited capacity and can only be used for 3-4 hours , that is, it needs to be charged at any time. Therefore, a portable charging box will be configured. [0004] There is a charging box method on the market today. The charging box has two th...
