Abstract

The present invention provides a method and system of monitoring the aged through sound by means of an internet of things. The voice recognition care nursing system comprises a host, at least one submachine and a care nursing unit. The submachine is installed in a room and configured to detect plural sound signals existing in the environment at the same time, and it is determined whether the sound signals are voice signals or non-voice signals or not through determining whether the sound signals have baseband-overtone structure or not; if the sound signals are voice signals, the content of the words and expressions of the voice signals are identified, and it is determined whether the sound signals include one of preset plural help information or not; if the sound signals are non-voice signals, it is determined whether the sound signals are one of preset plural abnormal sounds or not; if the content of the words and expressions of the voice signals is help information or the non-voice signals are abnormal sounds, the host is configured to send warning information to the care nursing unit and inform family members or a caregiver of inspection.

Description

A kind of method of Internet of Things sound monitoring old man and system thereof
Technical field
The present invention is the technology about a kind of house care and nursing, refers to a kind of method and system thereof of speech recognition care and nursing especially.
Technical background
Along with China is about to march toward aging society, medical care nursing quality is directly social concern with nurse shortage of manpower, People or handicapped person, to suffer from the be in security of daily life of heavy patient be the key factor affecting quality of life, therefore in the hypodynamic situation of present stage ward, how to maintain the home safety needing care and nursing object, making them can obtain succouring when there is emergency is the important problem of item.
Current part home for destitute or medical institutes be between every room mounting monitor to look after the situation of the old men, image-type and sound type two kinds can be divided into for the monitor of long distance nurse, wherein image-type uses the monitor of closed-circuit television or network communicating system to gather image, make supvr and care and nursing person can see the movement of all personnel in monitoring range, advantage is that all situations in monitoring range is all very clear, but shortcoming is that monitor has dead angle, and need people and look at supervision image always, in addition image-type monitor is comparatively useful in infant's care and nursing, for other age levels by care and nursing person shortage privacy.And the current rarely seen vagitus that is used on the market of sound type monitoring system is detected, People or care and nursing that is handicapped, that suffer from heavy patient cannot be applied in.
The present invention is directed to the disappearance of above-mentioned technology, propose method and the system thereof of a kind of Internet of Things sound monitoring old man, effectively to overcome above-mentioned problem.
Summary of the invention
Fundamental purpose of the present invention is providing a kind of method and system thereof of speech recognition care and nursing, its be room installing main frame or handset to monitor sound, judge that sound is voice or non-voice, distress signals whether are comprised or whether non-voice is urgent abnormal noise in further analyzing speech, to determine to start rescue mechanism the need of sending information warning, monitoring sound is without dead angle, and comparatively monitoring image is more accurate.
Another object of the present invention is providing a kind of method of speech recognition care and nursing, and it utilizes in the sound spectrum of voice signal whether to have fundamental frequency-general frequency structure to judge that whether voice signal is for voice.
The object of the present invention is to provide a kind of method of speech recognition care and nursing, it is stored in audio database by the feature of representative distress signals or abnormal noise, the distress signals or abnormal noise that analyze store in advance if having in voice signal, representative occurs outside may having a mind to, then send information warning.
In order to achieve the above object, the invention provides a kind of method of speech recognition care and nursing system, judge that whether environmental aspect is urgent by speech recognition care and nursing system, comprise the following steps: the plural voice signal in speech recognition care and nursing systems scan environment; Fundamental frequency-general frequency structure decision voice signal is utilized to be voice signal or non-speech audio; If voice signal is voice signal, then the words and expressions content of identification voice signal, judges whether the wherein a kind of of the plural distress signals comprising acquiescence, and if voice signal is non-speech audio, then judge that whether it is the wherein a kind of of default plural number kind abnormal noise; And if the words and expressions content of voice signal is distress signals, or non-speech audio is abnormal noise, then speech recognition care and nursing system external sends information warning.
The present invention separately provides a kind of speech recognition care and nursing system, comprise main frame, at least one handset and care and nursing unit, plural voice signal in handset detecting environment, main frame is connected in a wired or wireless manner with handset, after receiving voice signal, whether there is fundamental frequency-general frequency structure to determine whether voice signal by inspection voice signal, judging that the content of voice signal is the need of sending information warning further; Care and nursing unit is connected in a wired or wireless manner with main frame, if information warning sent by main frame, then care and nursing unit starts rescue mechanism, such as, set out nurse and go scene is actual visits whether someone needs relief.
The method of the speech recognition care and nursing that advantage of the present invention is to provide and system thereof install main frame or handset in a room to monitor sound, between every, estrade machine detecting sound is installed in room, be voice or non-voice by host analysis voice signal again, distress signals or abnormal noise whether is comprised in further analysis voice signal, to determine to start rescue mechanism the need of sending information warning, by judging that voice signal is voice signal and analyzes content wherein, speech recognition care and nursing system of the present invention more can be made to be used in People, the care and nursing of handicapped person or severe case, make sound type monitoring system no longer only for detecting vagitus, and can to being taked response by the emergency of care and nursing person, and by monitoring sound without dead angle, comparatively monitor image more accurate.
