Design Of Patient Vital Signs Information Monitoring System Based On ZigBee

With the continuous progress of science and technology and the aggravation of the aging problem,the majority of the people began to pursue a more outstanding quality of basic life,which makes the health monitoring equipment has a very ideal development potential.For conventional equipment,because it can not show the advantages of real-time,wearing comfort is not ideal,the economy is poor,the operation is difficult,so it greatly restricts the basic life of patients during hospitalization.Compared with conventional devices,wearable health monitoring devices can reflect the characteristics of diversity,with outstanding performance,small overall volume,relatively low power consumption,ideal portability,perfect function,strong economy,long-term stable operation,easy operation and high comfort.Therefore,wearable health monitoring devices are highly praised by the majority of users,depth,and rhythm of breathing to make a preliminary diagnosis of whether the human body is suffering from diseases.Multi-sensor and Windows operating system are used in this article to design a wearable vital signs monitoring system that monitors human vital signs in real time and has an emergency alarm function.This system is mainly divided into two parts:the lower computer and the upper computer.When the human body is breathing,the cyclical fluctuations produced by the abdomen.The heart rate is based on the periodic beating of the heart.According to these two characteristics of the human body,a polymer piezoelectric sensitive material is used to collect respiratory signals and heart rate signals.The second is to preprocess the breathing and heart rate signals,which includes signal filtering and the use of AD620 AN to amplify the heart rate signal.After that,the processed signal is converted to analog to digital by the STM32F103C8T6 single-chip microcomputer,and the respiratory frequency and heart rate Perform analysis,and finally display the calculated results on the OLED LCD screen.Finally,the processed data is transmitted to the ZigBee communication module through asynchronous serial communication.In the upper computer part,From an objective point of view,respiration and body temperature are the key indicators to evaluate the health level,and their changes can reflect the individual physiological conditions.In the process of clinical diagnosis,relevant scholars mainly develop a perfect monitoring system through sensors,so as to achieve excellent emergency alarm function.it conducts an ad hoc network to form a tree stump network to communicate with the lower computer,which is used to transmit the instructions issued by the upper computer to the lower computer and the vital signs data sent from the lower computer;use the SMS sending platform to send distress messages;in general,the Software has two major functions,namely: real-time display of vital signs data and emergency distress functions.Different vital signs signals are collected by various sensors in the system.Computers are selected as the terminal for displaying vital signs data,and smartphones are selected as the terminal for emergency calls,which realizes the monitoring of various vital signs of the user,and has a good Wearing comfort,easy operation,low power consumption and small size Comparing the monitoring of various signals in the state of lying and sitting,the data shows that the system has small measurement errors,high stability,and good robustness.It is very suitable for hospital inpatients and bedridden patients at home.Use for vital signs monitoring.
