Screening system for sleep apnea syndrome in family environment

The invention discloses a screening system for sleep apnea syndrome in family environment, comprising a snore data obtaining module, a snore processing module and a distinguishing module, wherein the data obtaining module is used for collecting the snore data; the snore signal processing module is used for firstly performing the preprocess of the voice signals such as framing, pre-emphasizing and window adding and then completing the end point detection for the snore by a double-gate detecting method; the first ten frame data of the snore sample is taken as the first measure of the background noise in the process of performing end point detection; and then the data of snore section is transmitted to an energy-ratio solution module. Finally, resolving the features of the energy ratio of the snore section and then transmitting the features of the energy ratio to the distinguishing module. The distinguishing module takes the energy ratio as the categorical data; if the energy ratio of a patient is higher than a certain threshold quantity, then the patient is distinguished as OSAS sufferer; if not, then the patient is the single snorer. The invention provides a system that brings less interference for the sleep of the patient and low cost and can still reach higher screening precision even in family environment.
