Embodiment 1

[0040] The present embodiment provides a method for measuring human respiratory rate, which at least includes the following steps:

[0041] S1: collect data signals related to the human body through the data collector;

[0042] S2: filter the data signal to obtain sample data;

[0043] S3: Determine the sample autocorrelation function based on the sample data;

[0044] S4: peak capture and measurement of sample autocorrelation function;

[0045] S5: Extract the respiratory frequency based on the peak value.

[0046] For ease of understanding, the following will discuss in detail based on each step.

[0047] S1: collect data signals related to the human body through the data collector.

[0048] When a person inhales, the thoracic diaphragm contracts and causes the chest cavity to expand. Natural inflation forces air into both lungs to equalize the pressure inside and outside the body. When the inhalation ends, the exhalation begins. During exhalation, the thoracic diaphr...

Embodiment 2

[0075] This embodiment is a further improvement on Embodiment 1, and repeated content will not be repeated here.

[0076] The present invention also provides an intelligent seat, which at least includes a seat cushion 3 and a backrest 4, wherein several sensors 1 are arranged on the seat cushion and the backrest to collect data signals related to the human body. The sensor 1 is preferably a capacitive sensor, and is arranged on the seat cushion and the backrest by connecting with a resistor to form a resistance-capacitance circuit, so that the current use state of the smart seat can be identified by measuring the change of the sensor capacitance.

[0077] preferred, such as Figure 5 As shown, the smart seat uses a total of 16 sensors 1 to form a data collection unit 13 to collect data signals related to the human body, among which 9 sensors are arranged on the seat cushion and 7 sensors are arranged on the backrest. Nine sensors are arranged on the cushion in a shape similar...

Embodiment 3

[0094] This embodiment is a further improvement on Embodiment 1 and Embodiment 2, and repeated content will not be repeated here.

[0095] The intelligent seat of the present invention also includes an identification unit 6 . The identification unit is configured to learn the working mode of the sitting behavior of the sitting person based on the machine learning algorithm. For example, in the process of touching the seat and sitting down completely, different occupants make the process last differently based on different sitting habits. For example, due to the different sitting habits of the seated people, the sitting steps will be completely different. For younger young people, they often sit down directly, which makes the instantaneous impact on the seat very strong. When the pressure data is processed and displayed through the time window, it will present a shape of sharp increase at a certain moment. For older middle-aged and elderly people, they often sit down slowly. ...

Abstract

The invention relates to a human body respiratory rate measuring system and an intelligent seat equipped with the same. The measuring system at least comprises at least one sensor that collects a first signal caused by physiological activities of a human body in a non-contact mode and a central processing unit that carries out operation processing on the first signal to obtain respiratory rate parameters of the human body. The central processing unit is configured as: selecting n peak points closest to the origin of time axis coordinates according to a percentage f of the total amount of the peak points so as to calculate an average value of the respiratory rate, wherein D is the total distance between a first peak point and an nth peak point; and re-determining the working mode of the remaining peak points with a percentage of 1-f in the operation result based on the average value of the respiratory rate.

Description

[0001] The present invention is a divisional application with the application number 201810833110.4, the application date is July 25, 2018, the application type is invention, and the application name is a physiological parameter measurement system and an intelligent seat equipped with the measurement system. technical field [0002] The invention belongs to the field of measurement technology, in particular to a physiological parameter measurement system and an intelligent seat equipped with the measurement system. Background technique [0003] Respiration rate is an important parameter of human body signs, how to realize the accurate measurement of this parameter through non-contact measurement method has always been one of the research hotspots in the field of biomedical engineering and instruments. Imaging photoplethysmography technology is a non-contact physiological parameter detection technology developed on the basis of PPG. This technology uses imaging equipment to co...
