| The increasingly fast pace of social development,the increasingly intense social competition,the ever-increasing cost of living and living pressure have led to the increasingly precious time of modern people and the increasing number of young people who choose to go to other places to work in big cities.The elderly at home are given very little time to spend with them,and their elderly parents are left to defend the"empty nest"[1].Old people become inconveniences,unattended,lack of nursing care when they are ill,and lack of help when accidents happen frequently.How to monitor and look after old people is a serious social problem that cannot be ignored.Years of family planning has gradually led to a negative population growth,aging,society has a large group of elderly,they undoubtedly need to be comprehensive and reliable guardianship.The monitoring system designed this time is a highly automated system,which realizes the monitoring of the elderly through voice recognition and environmental monitoring,without the need to question the quality and ability of the nursing home or nursing workers[2].And to old person itself,believe they prefer to live in comfortable,familiar environment.The goal of this study is to develop a high-tech/Internet model and a diversified elderly monitoring system with voice recognition technology.There are two common monitoring methods for the elderly.One is through the nursing home institutions for the elderly to monitor the elderly or through the nanny and nursing teacher to achieve the monitoring of the elderly,the cost is expensive.Because the old people in the nursing home are more and less care workers and the quality of care workers is uneven,so it is not very comprehensive and safe to protect the elderly,which brings hidden dangers and costs will be out of control.The advantages of this voice monitoring system compared with the nursing home monitoring method are as follows:1.Low cost.2.High rationality and controllability.3.Suitable for elderly people who are willing to stay at home.One is to monitor the living conditions and environmental information of the elderly in the family through camera technology.However,the monitoring system based on camera vision technology is often unable to realize real-time monitoring if the shooting of the elderly is not in place or face capture is not complete.Compared with the monitoring method based on visual technology,this voice monitoring system has the following advantages:1.Better security.2.No invasion of privacy.3.High controllability.The system designed in this paper will take the environmental monitoring function as the auxiliary and the voice recognition function as the leading function to design a set of monitoring system for the elderly living alone with stronger security.In environmental monitoring sensors,such as laser,temperature and humidity,human infrared,photosensitive resistance as well as various types of gas sensors and integrated environmental monitoring functions as auxiliary,to distinguish the characteristics of housing area and place the relevant sensors,and identify the home relevant environmental factors and analysis of the existence of abnormal data.Based on the speech recognition technology,a microphone is placed at the place where the elderly usually stay in the home,and the collected speech segment is saved to identify whether the elderly emit abnormal speech according to the template.The monitoring system has the functions of active alarm and passive inquiry.When the system analyzes abnormal environment data or abnormal voice,the system takes the initiative to send abnormal information to the customer terminal.Or by the guardian or care workers in WeChat way to ask the system host,real-time access to the current monitoring system information.In order to apply the speech recognition technology to the monitoring system more efficiently,the system has been tested and verified for many times.The test proves that this set of monitoring system has perfect function and practical use value. |
