AI Technical Summary

Problems solved by technology

However, using human voice to directly wake up is also easy to cause false triggers. For example, it is easy to trigger voice detection to wake up when chatting indoors. To solve this problem, now after human voice is detected, specific keywords are added to further detect whether it needs to be woken up; However, the power consumption is about 100ua when it enters the human voice detection, and about 2ma when it enters the keyword detection. For products that do not have a long power supply, frequent triggering will also consume a lot of energy and reduce the service life of the lithium battery.

Embodiment Construction

[0050] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0051]The invention discloses a method for waking up an intelligent electronic device. An infrared sensor is used for passive detection. When the infrared sensor detects a human body, the voice module is awakened to detect the human voice. When the voice module detects the human voice, The wake-up keyword detection is further performed, and when the voice module detects the wake-up keyword, the face recognition unit is woken up to perform face recognition.

[0052] refer to figure 1 , is a method for waking up an intelligent electronic device disclosed in the present invention (in this embodiment, the intelligent electronic device is a door lock), and the specific steps are as follows:

[0053] S01: Infrared sensor passive detection;

[0054] S02: After the infrared sensor detects a human body, trigger an interrupt to the first processing unit;

[0055] S0...

Abstract

The invention relates to an awakening method of intelligent electronic equipment. An infrared sensor is adopted for passive detection; after the infrared sensor detects a human body, a voice module isawakened to carry out human voice detection; after the voice module detects human voice, awakening keyword detection is further carried out; and after the voice module detects awakening keywords, a face recognition unit is awakened to carry out face recognition. False triggering of the human face recognition unit is reduced, the human face recognition unit is in a standby state for more time, power consumption is reduced; and the service life of the whole system is prolonged under the condition of the same battery power.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a method and system for waking up an intelligent electronic device. Background technique [0002] With the improvement of living standards, various smart devices emerge in an endless stream. This is especially true for the home furnishing industry that is closely related to living and living; for example, smart face door locks, when people approach the door, after successful face recognition, the door can be opened without feeling, which greatly improves people's quality of life. However, due to the high power consumption of the face recognition system, with a peak value of 500ma, due to energy consumption considerations, the face recognition system will enter standby or power-off mode. Identification; common wake-up methods are as follows. [0003] Wake up by distance sensor detection: wake up the face recognition system after detecting a person through a dista...
