Research On Monitoring System Of Vital Signs Based On LabVIEW

Chronic diseases severely threatening the health of mankind,in recent years,our government pays more and more attention on protection and treatment of chronic diseases,cardio-cerebral vascular disease as a representative of chronic diseases has also attracted more and more attention.Signaling signals on patients with cardiocerebral vascular disease require long-term real-time monitoring,at present,the wearable equipment on the market can monitor some signs of signal,but its accuracy can not reach the medical level,and there is not a information platform to unified manage sign signal.The research of wearable life tracking system is designed t o solve these problems.The research content of this topic is divided into three parts:hand-ring monitoring terminal,mobile phone APP and medical information platform.The hand-ring monitoring terminal uses digital sensors and highly integrated analog front ends to monitor important signs of cardio-cerebral vascular disease: body temperature,ECG and oxygen saturation,and pass the collected sign signals to smart mobile phone by bluetooth.Mobile APP in this topic mainly play the role of extending the transmission distance.The smart phone receives the sign signal that collected by the hand-ring monitoring terminal through the bluetooth,and transmits the collected sign signal to the remote LabVIEW-based life information management system through th e Wifi/GPRS network and stores it in the database.Then t he cloud-based medical information platform manages the signals by operating the database.This topic chooses the Android operating system as the development platform,in the simulator to simulate the receive and send of sign signal,and then transplant it to the smart phone.The medical information platform of this topic is based on the cloud computing,and LabVIEW-based life information management system plays the role of receiving,processing and storing the sign signal.The specific functions of LabVIEW-based life information management system include:(1)Build life information management system,including the login system.(2)Use the TCP/IP protocol to design the sign signal rec eption procedure.(3)The system make processing and calculation of the received sign signal,wherein the ECG signal and the body temperature signal are received in a packet form,and the noise reduction processing is carried out with the moving average method and the wavelet transform.But,for the oxygen saturation,because the collected signal is not a direct oxygen saturation value,so the further calculated is needed to get oxygen saturation value.(4)Access the Access database through the DB control in LabVIEW and store the sign signals in the database.The medical information platform based on the cloud computing through the operation of the database to achieve the further management of sign signal.
