Abstract

The invention provides a signal quality evaluation method and device, electronic equipment and a storage medium, and the method comprises the steps: extracting a target signal from a first original signal outputted by a signal collector, calculating the ratio of the energy of the target signal to the energy of the first original signal, the first ratio being capable of reflecting the intensity of the target signal, and the second ratio being capable of reflecting the intensity of the first original signal; namely reflecting the signal-to-noise ratio of the first original signal, then calculating a second specific value of energy of the first original signal to the full-value signal, determining a quality score of the first original signal according to the first specific value and the second specific value, and evaluating the quality of the first original signal according to the quality score. Therefore, the quality of the first original signal is evaluated, and the strength of the first original signal and the strength of the target signal are both considered during calculation of the quality division, so that the quality evaluation result of the first original signal according to the quality division can reflect the quality of the target signal in the first original signal.

Description

Technical field [0001] The present application relates to device assessments, in particular to a signal quality assessment method, device, electronic device, and storage medium. Background technique [0002] As people pay more and more attention to sleep problems, all kinds of products related to sleep are increasingly rich. Currently, many products related to sleep In order to provide users with better services, it is often necessary to use physiological signal detection devices to obtain user physiological signals. [0003] At present, most physiological signal detection products require the use of a particular signal collector to collect the user's signal, and then filter the signal to which the signal collector output from the physiological signal is used to obtain the user's physiological signal. Physiological signals typically include weak signals such as heartbeat signals, respiratory signals, so signal collectors typically need to enlarge the collected signals, and then o...
