Human Health Monitoring System Based On Zigbee And GPS

With the increasing life rhythm,irregular diet,affected by environmental pollution and unhealthy lifestyle such as irregular diet,sleep debt,lack of exercise,smoking and drinking,people’s health is not optimistic.According to low employment efficiency,inadequate medical resources and previous human health monitoring system which is not conducive to the user to understand their own health data and physical potential problems at any time.This paper proposes a human health monitoring system based on ZigBee and GPS which can help the public monitor their health condition at any moment to improve the quality of life.This paper mainly has completed the following work:(1)The existing human health monitoring system has the disadvantages of weak operability.It can not provide home care services and accurate positioning for users.To solve these problems,this paper proposes the overall design scheme of human health monitoring system based on ZigBee and GPS.The system designed in this paper makes the user’s life more convenient and timely understanding of their health status.When users’ body is uncomfortable,medical staff will be informed of the user’s information and rushed to the incident place timely.(2)In view of the shortcomings of the existing human health monitoring system,such as low positioning accuracy,unitary system,user passivity and so on,this system combines GPS positioning technology to locate the position accurately.When the user is physically abnormal,the system automatically obtains all user information and sends the information to the nearest hospital and medical personnel in the shortest period of time.The nearest medical staff will be rushed to the user’s geographical location,and carry the necessary medical tools on the spot to the user for medical treatment.Similarly,the system provides different hospital information(such as medical facilities and medical information)and travel information for the user to choose.(3)In view of the shortcomings of the existing human health monitoring system,such as no direction,low flexibility,poor real-time performance,weak intelligence and so on,the system can real-time and accurately track the location of medical staff and users based on the Dijkstra shortest path algorithm.According to the current location of the two sides,the system provides the shortest path which is constantly changing in term of geographical location.The user decides whether to go to the hospital or arrange the medical staff to home.(4)The system uses the ontology knowledge base technology to establish the user file management database which solves the problems of the existing human body health system,such as less data,less information updating,Information supply and user needs are not corresponding,and so on.The system tracks the user’s physiological information and updates it in real time which will be compared with the initial user information.The system will record the change of the information and provide pertinent information to the user.(5)For each module,the system completes the circuit design,hardware design and software design.The hardware design consists of body temperature module,pulse module,microprocessor module,GPRS module,voice prompt module,LCD module and wireless transceiver module.The software design mainly includes the physiological information collection function,the user localization function,the recommended function of the shortest path for medical staff.The system combines the ontology knowledge base technology to realize the user consultation function.The feasibility and reliability of the system are verified by functional test.
