Abstract

The invention discloses bowel sound detection method, device and system under noisy environment. The bowel sound detection method comprises steps of collecting a bowl sound mixed signal of a current user through a sensor, wherein the bowl sound mixed signal comprises a bowl sound signal and an environment interference signal; converting the bowl sound mixed signal to a digital signal; extracting a time-frequency spectrum characteristic of the digital signal; inputting the time-frequency spectrum characteristic of the digital signal into a trained convolution nerve network to process; and detecting a time point when the bowl sound happens so as to distinguish the bowl sound signal and the environment interference signal. The bowel sound detection method, device and system under the noisy environment utilize a difference of the time-frequency spectrum characteristics of the bowl sound signal and the environment interference signal, train a convolution nerve network to distinguish the bowl sound and the interference sound, can finish the detection on the bowl sound under the noisy environment, and can help to improve the accuracy of the bowl sound detection.

Description

technical field [0001] The invention relates to the technical field of biomedical signal processing, in particular to a method, device and system for detecting bowel sounds in a noisy environment. Background technique [0002] The intestine is the longest tube in the digestive organs, and its main function is to digest and absorb food. Once the intestinal tract is abnormal, it may cause digestive and absorption disorders, as well as a series of related symptoms. Therefore, the diagnosis of intestinal diseases is very necessary. Bowel sounds auscultation is a commonly used non-invasive examination in the diagnosis and treatment of intestinal diseases. [0003] In the current diagnosis and treatment process, the collection and identification of bowel sounds mainly rely on manual auscultation by physicians. Bowel sounds originate from the movement of the intestinal tract, and their appearance is sparse in the time range. Therefore, the auscultation process of bowel sounds ge...
