Guarding system, mattress, alarm system and sleep state recognizing method of guarding system

Abstract

The invention discloses a guarding system, a mattress, an alarm system and a sleep state recognizing method of the guarding system. The guarding system comprises a pressure sensor, a data acquisition unit and a processor, wherein the pressure sensor comprises a piezoelectric electret film, a first metal grounding electrode, a metal positive electrode, a first insulated isolation layer and a second insulated isolation layer, the first insulated isolation layer and the second insulated isolation layer are arranged on two opposite sides of the piezoelectric electret film, the first metal grounding electrode is arranged between the piezoelectric electret film and the first insulated isolation layer, the metal positive electrode is arranged between the piezoelectric electret film and the second insulated isolation layer, and the first grounding electrode, the metal grounding electrode and the metal positive electrode are electrically connected with the data acquisition unit respectively. The guarding system has the advantage that a more efficient guarding tool is supplied to parents or keepers since an infant sleep state can be recognized. The invention further provides the mattress assembled with the guarding system, the alarm system applying the guarding system and the sleep state recognizing method of the guarding system.

Description

technical field [0001] The present invention relates to a monitoring system, in particular to an infant respiratory monitoring system, a mattress equipped with the infant respiratory monitoring system, an alarm system using the infant respiratory monitoring system, and a sleep state recognition method of the infant respiratory monitoring system . Background technique [0002] Infants and toddlers enter a light sleep state when they go to sleep. During light sleep, it will move its trunk and limbs and sob softly from time to time. The whole sleep process is not quiet, and it occasionally opens its eyes for a short time. It can cause startle action. About 1 to 2 hours after light sleep, they will enter deep sleep. Infants and young children in deep sleep are relatively quiet, their faces and limbs are in a relaxed state, and their breathing is very even. Parents or guardians will check from time to time like obsessive-compulsive disorder whether the infant kicks or rolls to...

AI Technical Summary

Problems solved by technology

[0004] 1. At present, non-invasive flexible respiratory monitoring mattresses mainly use PVDF piezoelectric film as the pressure sensor, which is more expensive;

[0005] 2. The piezoelectric electret film is used as a pressure sensor, and its anti-electromagnetic interference ability is low;

[0006] 3. Existi
