Problems solved by technology

[0004] In the existing technology, the sleep posture is analyzed through the pressure images of various parts of the body, but this technology does not deeply dig out the fine-grained characteristics of the force of each body posture, and increases the cost of the system based on the array distribution

Embodiment

[0023] Such as figure 1 As shown, the sleep posture recognition device based on the cardiac impact signal proposed by the present invention includes a sensing front-end module 100, a conditioning circuit 101, and a microprocessor 102. The sensing front-end module 100 includes a housing 1010, and a pressurized The electric ceramic 1011, wherein the housing 1010 is made of PP plastic material, and the piezoelectric ceramic 1011 is pasted on the inner surface of the upper cover of the housing 1010 with special glue. The piezoelectric ceramic 1011 is used as a signal collector, which can convert the pressure signal into an electrical signal, and output the acquired pressure signal to the corresponding processor (microprocessor) in the form of a voltage or current signal; the sensor front-end module 100 is placed on the bed The lower part of the pad is placed close to the chest to collect the individual's cardiac shock signal.

[0024] The conditioning circuit 101 includes an RC f...

Abstract

The invention provides a sleep posture recognition method based on a ballistocardiogram signal. The sleep posture recognition method comprises the steps that S1, acquiring the ballistocardiogram signal; S2, judging the relationship between the amplitude of the ballistocardiogram signal and a set threshold value; S3, calling the waveform characteristics of the ballistocardiogram signals; S4, inputting the waveform features into an integrated logistic regression classifier; S5, outputting four different sleeping postures; and S6, counting and calculating the time proportion of each sleeping posture, and sending a self-defined reminding message to the client. According to the method, the heart impact signal is acquired, and then the heart impact signal is analyzed to acquire the sleep posture, so that video monitoring is avoided, and the privacy of a user is protected.

Description

technical field [0001] The invention relates to the medical field, in particular to a sleep posture recognition device and method based on cardiac shock signals. Background technique [0002] Sleep monitoring plays an important role in identifying sleep disorders to aid diagnosis and treatment. Sleep posture recognition can better determine the time the subject maintains a certain fixed posture. If you maintain a fixed sleeping posture for a long time, you will have decubitus symptoms. Frequent changing of sleeping positions is a key factor leading to poor sleep quality. [0003] The current routine sleep quality monitoring adopts the polysomnography system. In addition to collecting vital sign information such as multiple physiological parameters of the subject, the system also adds a bedside camera to collect sleep image information to more accurately determine whether the subject is sleeping. The body posture changes during the process, but the recording method of video ...
