Embodiment Construction

[0034] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0035] refer to figure 1 , an embodiment of a method for accurately sensing indoor activities of the present invention is proposed. The method can include:

[0036] Step S11, receiving the vibration signal of the indoor ground through a plurality of vibration sensors arranged according to preset rules;

[0037] Step S12 , judging the position of the vibration source according to the phase difference of the vibration signals of the same vibration source in different vibration sensors.

[0038] The above-mentioned method for accurately sensing indoor activities can sense the vibrations caused by activities such as walking on the indoor ground through a plurality of vibration sensors with relatively fixed distances, and can analyze the phases of vibration signals on vibration sensors at different positions, and can acc...

Abstract

The invention discloses a method and device for accurately sensing indoor activities. The method comprises the steps that shake signals of the indoor floor are received through a plurality of shake sensors distributed according to a preset rule; the position of a shake source is judged according to the phase difference, in the different shake sensors, of the shake signals of the same shake source. By means of the method and device for accurately sensing the indoor activities, the indoor activities can be monitored on the premise of not disturbing a monitored person, and concern about leakage of the privacy of the monitored person can be eliminated.

Description

technical field [0001] The invention relates to the technical field of vibration perception, in particular to a method and device for accurately sensing indoor activities. Background technique [0002] In the prior art, if one wants to know indoor activities (usually people's activities), it is usually necessary to wear sensing equipment on the human body or use video monitoring equipment. [0003] Wearable sensing devices need to be worn on the human body to be used normally, which is cumbersome; while monitoring devices can easily lead to leakage of personal privacy in daily life, and the recognition calculation is complicated, so it is currently not suitable for commercial applications. Contents of the invention [0004] The main purpose of the present invention is to provide a method for accurately sensing indoor activities, which can effectively monitor indoor activities and is convenient and practical. [0005] The present invention proposes a method for accurately ...
