| With the development of China's national economy,the improvement of health care services and the change of the age structure of the population,the aging problem should not be overlooked.With the accelerated aging of the population at the same time,heart disease,hypertension,Alzheimer's disease and other diseases of the elderly are becoming more and more.But the traditional medical care equipment has many disadvantages,:large size,high cost,fixed location and wiring complex shortcomings,which limited the Medical care equipment in the actual treatment of chronic diseases in the application,and the existing medical and health services resources are short and unbalanced,far enough to meet the huge demand for the elderly for health care for the elderly.Multi-disciplinary and multi-technology combined with the rapid development of wireless sensor network technology has brought new opportunities in medical field,medical care method based on wireless sensor technology gradually accepted by the public,it combined a number of technologies,such as wearable physiological detection methods,sensor network technology,electronic information technology,network information technology and wireless communication technology,it can monitor the patient's physiological parameters and health status in real time and assist professional medical staff to remote diagnosis of patients and treatment.This paper developed a wireless medical monitoring system based on Zig Bee network.Through the sensor node of the system,the physiological data such as body temperature and heart rate are collected and wirelessly transmitted to the remote host computer to realize the monitoring of the information of the patient's symptoms.At the same time,the design of the ward sensor nodes to collect temperature and humidity,smoke concentration and other environmental information to protect the safety and comfort of the rehabilitation environment.Zig Bee wireless technology as one of the most popular communication technologies in recent years,It has the characteristics of low power consumption,low cost,short delay and close distance,based on this technology to build a wireless medical monitoring system,also has the features of wireless,node can carry,low cost,long working hours,easy maintenance management.The CC2530 chip is used as the core hardware of the system,and the peripheral circuits such as sensor acquisition module and power management module are designed to collect the physiological data such as body temperature and heart rate and the environmental information such as temperature and humidity and smoke concentration.The networking of the coordinator node and the sensor node and the wireless network communication are realized through the Zig Bee protocol stack.The wireless communication between the coordinator node and the monitoring center is realized by the Wi Fi module.The module uses the transmission function between the serial ports of the CC2530 Data transmission,the information will be forwarded to the monitoring center,health care workers can be developed in Visual Studio 2015 monitoring system PC software real-time monitoring of the patient's physiological data and environmental conditions,while the relevant data can be saved and processed.After being tested,the system can collect the necessary physiological parameters and environmental information and sent them to the host computer wirelessly,the host computer can also display the relevant data in real time,at the same time,historical data can be viewed and saved,it achieved the design of the program.It has certain reference value and practical significance for the research of wireless sensor network in medical care. |
