Pressure distribution monitoring feedback system of intelligent mattress

Abstract

The invention discloses a pressure distribution monitoring feedback system of an intelligent mattress. The system comprises a pressure sensor, a controller and a pressure supporting matrix, the pressure supporting matrix is arranged below the pressure supporting matrix, the pressure supporting matrix comprises a plurality of supporting pieces which are arranged in an array mode and can adjust pressure, and the output end of the pressure sensor is connected with the input end of the controller. The system has the advantages of scientific structure and reasonable design; the pressure distribution monitoring and feedback system of the intelligent mattress can monitor and feed back the distribution of sleep pressure generated by a sleeper on the mattress, and is simpler, more convenient, faster and lower in cost; the pressure distribution of the intelligent mattress is monitored and fed back in a piezoelectric fiber network array form; the three columns of piezoelectric fibers are interwoven in the transverse direction, the longitudinal direction and the oblique direction to form a network array, a plurality of triangular arrays are formed and connected to the pressure driving unit tofeed back and control the pressure at the position of the mattress, and therefore, the sleeper can fall asleep on the mattress with the satisfactory comfortable hardness.

Description

technical field [0001] The invention relates to a smart home, in particular to a smart mattress system. Background technique [0002] With the continuous improvement of living standards and health awareness, people have higher and higher requirements for sleep quality. And there is a direct relationship between sleep quality and health, and sleep quality is related to mattresses, so it is of great significance to monitor and feedback mattresses that affect sleep quality. Monitoring and feedback by means of camera monitoring may cause moral issues such as spying on privacy; the use of wearable devices can easily interfere with people's daily normal life behavior. [0003] As a new, simple and non-interfering monitoring method, smart mattress has become a research hotspot and has been widely welcomed in recent years. Its core technology is intelligent monitoring and feedback control of pressure, which involves various technical means. Among them, the optical fiber array tec...

Problems solved by technology

The method of using gas or liquid to monitor pressure is also often used this year, but the detection and feedback of pressure often requires complex drive adjustment and pipeline design; traditional piezoelectric element arrays usually require N2 piezoelectric sensing elements on a square surface , which is huge consumption for pressure distribution monitoring
