Sleep quality data acquisition device and monitoring system based on surface acoustic wave sensor

Abstract

The invention relates to a sleep quality data acquisition device and monitoring system based on a surface acoustic wave sensor. The device comprises a tension transmission column, a patch type surface acoustic wave sensor, and a transmission antenna module. The tension transmission column is connected with skin of a user, and is used for transmitting heart beat pressure of the user; the patch type surface acoustic wave sensor is connected with the tension transmission column, and is used for converting the heart beat pressure of the user to an electrical signal, at the same time achieves the exchange of the electrical signal and a surface acoustic wave signal; the transmission antenna module is connected with the patch type surface acoustic wave sensor, and is used for receiving an external excitation electrical signal and transmitting the external excitation electrical signal to the patch type surface acoustic wave sensor, at the same time wirelessly transmits the electrical signal transmitted by the patch type surface acoustic wave sensor; the system comprises the sleep quality data acquisition device and a control terminal which has two-way transmission with the sleep quality data acquisition device; the control terminal also comprises a signal interaction module and a sleep quality analysis module. Compared with the prior art, the sleep quality data acquisition device and the monitoring system have the advantages of high safety coefficient, nonbreakable monitor, strong anti-interference ability, high monitor sensitivity, stable performance and the like.

Description

technical field [0001] The invention relates to the field of surface acoustic waves, in particular to a sleep quality data acquisition device and monitoring system based on a surface acoustic wave sensor. Background technique [0002] With the development of science and technology, modern technology is gradually integrated into people's daily life. Real-time monitoring of human heartbeat is of great help to people's mastery of their own health, especially the elderly. After monitoring the heartbeat pressure and frequency, by analyzing the relationship between the parameters and the sleep quality, the sleep quality of the user in the time period of use can be obtained. Only by mastering the sleep quality of each time period can we analyze and improve the sleep quality based on this. In particular, the role of the patch as a signal monitoring device in this monitoring system is very important. Therefore, this patch-type surface acoustic wave sensor has a huge room for develop...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, in order to solve the above problems, a monitoring system composed of active sensors, power supplies, transmission units, etc. is generally used to detect heartbeat or pulse, but this detection method has the following disadvantages: 1. The existing active sensors Due to the need for power supply, and the power supply is prone to run out of power during use, it is impossible to monitor the sleep time in the future, and because the patch is relatively close to the skin, there are greater safety hazards, such as leakage, etc.

2. The signal acquisition device in the prior art is heavy and bulky, and placing it close to the body will make it uncomfortable and affect the normal sleep quality of the user

3. The implementation of the prior art has poor anti-interference ability, and the measurement results are easily affected by temperature, humidity, and interference pressure, and large deviations will occur when analyzing data
