Research On Application Of Wireless Sensing Network Technology In Healthy Project

With the development of communication technology, telemonitoring system makes the monitoring range from hospital to anyplace where the communication network can reach. It realizes the transmission of information between patients and cliniques, cliniques and hospitals, also hospitals themselves. Telemonitoring provides a method researching object's physiological functions through series monitoring of physiological parameters. It will shorten the distance between doctors and patients. Doctors can provide medical service for the sufferers by the help of the information from long distance. It is significative for sufferers to get a high level medical service in emergency. Therefore, it is reasonable to develop a wireless monitor system based on the parameters of human's health, which is economical and humanistic.In the presence of singlechip, sensing technology, microcomputer, and modern wireless communication technology, this paper presents a wireless monitor system based on the parameters of human's health, which is small, low power consumption, real-time and safe. The system extracts people's life indication parameters with various sensors in time. These parameters will be processed by pre-circuit, controlled by singlechip, transmitted and received by wireless system, after that carried in the computer through USB interface. Then with the help of internet, the information is transmitted to telemedicine organization or other system, and it will provide important data for doctors to monitor people's health state.The system can be divided into three modular by function, sensing data acquisition part, wireless data transmitting part, and universal serial interface part. We use AT89C52 to be core control device. The parameters including body temperature, pulse and so on, which are got by sensors, disposed by pre-circuit, are supplied for wireless transmitting modular. We choose PTR8000 integrated with nRF905 as wireless transmitting and receiving device, which makes the system convenient and safe. The universal serial interface modular is used for communicating with the computer, which transmit the collecting data to the computer in time. The system is small in size, safe, plug and play, and convenient.There are six chapters in this thesis. The first chapter concluded the background of this technology, and gave the summary of this paper and put forwards the design. The second showed the monitoring principle and the whole system design. The third chapter...
