In particular, the invention sets the ratio of the difference between the maximum value and the minimum value of the sound frequency in the sound fragments to be marked and the average value as the frequency variation degree of the sound, and compares the frequency variation degree with the preset frequency variation degree, and the longer the frequency variation degree is, the longer the time period is selected as the adjacent fragments, so as to prolong the marking time point, and the time point is used for obtaining the sound fragments marked by the object to be monitored, so that the monitoring module can judge the cough condition of the object to be monitored for monitoring.
Particularly, the method marks the abnormal sound locus of the object to be monitored, obtains the marked interval time according to the marked abnormal sound locus of the object to be monitored stored in the storage module, if the interval time is too short, the abnormal sound occurrence frequency of the large object to be monitored is proved to be too high, the object to be monitored is indicated to be cough, warning is carried out, the situation that children are not aware of cough is avoided, the interval time is longer than the preset interval time, the monitoring module further judges whether the cough condition of the object to be monitored is more accurately judged according to the frequency change degree of the abnormal sound fragment of the current mark and the abnormal sound fragment of the last mark in the unit interval time, if the frequency change degree of the abnormal sound fragment of the current mark and the abnormal sound fragment of the last mark in the unit interval time is smaller than the preset standard value of the frequency change degree in the unit time, the fact that the adjacent mark abnormal sound is not greatly changed is proved, the object to be monitored is not cough, the reason that the abnormal sound fragment of the object to be monitored is probably continuous sound emission of the object to be monitored is probably caused, and if the frequency change degree of the abnormal sound fragment of the current mark and the abnormal sound fragment of the last mark in the unit interval time is larger than the standard value of the frequency change degree of the preset unit time is proved to be cough.
