The Design And Implementation Of Old-age Home Fall Remote Monitoring System Base On Cloud Backstage

With the development of society,the problem of population aging has been highlighted in developed countries and some developing countries.At present,with the number of elderly people in China is growing,the pressure on social pensions is increasing.The home-based endowment is a new style to provide for the elderly which is suitable for the realistic context of our county,and plays an irreplaceable role in providing for the elderly.When the old man at home fainted by disease or accidentally fell down because they cannot use their hands or feet well,they are difficult to be detected and rescued in the first time.At present,the use of video surveillance for the elderly at home not only needs committed staff observe the state of the elderly in real time,but also causes the problems of high cost and invasion of the privacy of the elderly.The fall alarms and other equipments are not accurate enough for the fall detection.If the old man fell without much damage,the alarm cannot be cancelled in time after they stand up.The old man’s family members,doctors,and community managers cannot view the status of the elderly through the background data at the same time and the data cannot be shared.It is difficult to provide real-time nurse and timely care for the elderly.To solve the above problems,the design and implementation of old-age home fall remote monitoring system base on cloud backstage is put forward in the thesis.The system used wearable equipment to detect tumble,which saves cost and has high privacy.When the old man stood up after they fell down,the system could automatically detect the station and cancel the alarm to improve the accuracy of the fall detection.The old-age home fall remote monitoring system was set up in the cloud server.The cloud backstage could analyze,display and save the dropping information of old people,realized the sharing of data.The main contents of this thesis are as follows:(1)In order to realize the function of falling and standing up judgment,the three-dimensional acceleration and angle changes of human activities were test and measured,and the motion characteristics of falling and standing up were analyzed to deduce the judgment algorithm.(2)In order to ensure the accuracy of the fall and stand-up detection,the MPU6050 was selected as the sensor for detecting the fall acceleration and the angle of z axis of stand-up after the fall.The main control chip adopted the Arduino UNO R3 single-chip microcomputer,and the communication mode was GPRS.(3)The cloud server was set up in order to achieve real-time sharing of background data.(4)The PC software was designed in C# language to receive,displayed and saved the data sent by the hardware.(5)The functions of system were test and verified,and the false positive rate of the system was counted.On the basis of the above research work,the design and implementation of old-age home fall remote monitoring system base on cloud backstage was finally completed.The accuracy and timeliness of system was improved,and the remote monitoring the falling of old-age home and the function of sharing data by cloud backstage were realized.
