A data acquisition system for an intelligent mattress

Abstract

The invention relates to a data acquisition system for an intelligent mattress. The data acquisition system at least comprises a data acquisition unit arranged on the intelligent mattress and provided with a plurality of acquisition channels and an intelligent terminal for data interaction with the data acquisition unit. The data acquisition system for the intelligent mattress selects acquisition channels for acquiring the physiological signals of a user according to the class of the intelligent mattress used by the user; the data acquisition unit converts the acquired physiological signals into AD voltage values with an A / D converter, preprocesses the AD voltage values, and then sends the preprocessed AD voltage values to the intelligent terminal assigned by the user and / or located beside the intelligent mattress via a communication device; and the intelligent terminal carries out calculation according to the screened physiological signal acquired by the acquisition channel with a preprocessed AD voltage value meeting a set threshold so as to obtain the physiological data of the user on the intelligent mattress.

Description

technical field [0001] The invention relates to the technical field of smart home, in particular to a mattress integrated with smart hardware, and in particular to a data acquisition system for a smart mattress. Background technique [0002] Smart hardware is the core content of smart home. Statistics show that people spend one-third of their lives in bed. Therefore, it is very meaningful to combine intelligent hardware with mattresses for disease prediction or monitoring of patients' physical conditions. [0003] In addition, with the arrival of my country's population aging trend, the health problems of the elderly living alone have become increasingly prominent. The unique physiological characteristics of the elderly require special care, and some elderly people even need to pay attention to their physiological changes and sleep status at all times. At present, the testing methods of sleeping posture and sleep behavior mainly include polysomnography recording method, a...

Problems solved by technology

[0006] (1) The signal collected by the piezoelectric unit is used for processing to obtain the user's breathing, heartbeat and other signs before filtering the collected signal. Due to the influence of the interference signal, the accuracy of the analysis result is low. In addition, some The signals collected by each piezoelectric unit are all used for processing to obtain the user's breathing, heartbeat and other signs. Due to the large amount of data processing, the data processing efficiency is low.

[0007] (2) In the absence of a communication connection, the smart mattress cannot upload the collected user data to the smart terminal and / or cloud service management system for storage and / or data processing. At this time, it is often easy to cause data loss. In case of an abnormal state, it is also impossible to alert the user of the abnormal state based on the collected data

[0008] (3) The battery capacity of the smart mattress itself is limited, and the long-term communication connection between the smart mattress and the smart terminal and / or cloud service management system and the exchange of data for a long time will consume a lot of battery power, which is not conducive to the long-term use of the smart mattress. keep working
