Awakening method and device based on low-power-consumption Bluetooth radio frequency

Abstract

The invention discloses an awakening method and device based on low-power-consumption Bluetooth radio frequency, and the method comprises the steps: 1, carrying out system booting of an awakening terminal, and enabling high-power-consumption equipment to enter into a low-power-consumption state: shutdown or sleep; 2, enabling low-power-consumption Bluetooth slave equipment to enter into an intermittent work mode after the system booting of the awakening terminal; 3, enabling low-power-consumption Bluetooth main equipment of a control terminal to send a control instruction; 4, enabling low-power-consumption Bluetooth slave equipment of the awakening terminal to respond to the control instruction, and awakening the high-power-consumption equipment to work; 5, returning to step 2 after the low-power-consumption Bluetooth slave equipment of the awakening terminal completes an awakening task. The device comprises the equipment with a low-power-consumption Bluetooth slave, the awakening terminal formed by the high-power-consumption equipment which can be awakened by the equipment with the low-power-consumption Bluetooth slave, and the control end which consists of equipment with the low-power-consumption Bluetooth main unit. The method and device achieve the awakening of the high-power-consumption equipment in the air based on the radio frequency of low-power-consumption Bluetooth, and reduce the energy consumption of the high-power-consumption equipment.

Description

technical field [0001] The invention relates to a low-power bluetooth radio frequency wake-up method and device. Background technique [0002] Bluetooth Low Energy is an upgraded version of Bluetooth 3.0 (including Bluetooth 4.0 and later), which is more power-saving, low-cost, 3 milliseconds low-latency, ultra-long effective connection distance, AES-128 encryption, etc. than version 3.0; it is usually used in Bluetooth headsets, Bluetooth speakers and other devices. [0003] Radio frequency wake-up technology is a method of using wireless signals to wake up devices, and is mainly used in devices with low power consumption requirements. [0004] Bluetooth Low Energy is a supplement to the Bluetooth 3.0+HS specification. It is specially designed for wireless solutions that have high requirements for cost and power consumption. It can be widely used in many fields such as health care, sports and fitness, home entertainment, and security. It supports two deployment modes: dua...
