Research And Application Of Wireless Network In Medical Monitoring System

The traditional ways of medical care is mainly patients under the care of doctor or nurse accompanied,by special measuring instrument to obtain patient information,with the rapid development of computer technology,communication technology,the traditional mode of monitoring is complicated,and in many disadvantages.Wireless sensor network in the mobile space flexibility and real-time sensor testing advantages based on the above background,the wireless sensor network technology in traditional health care system,establish a new generation of wireless sensor network remote medical monitoring system based on.This system will improve the traditional health care system in time and space limitations,to improve flexibility,real-time medical monitoring system is a set of monitoring,medical and information management in one of the performance optimization of medical monitoring system.Firstly the topic research background and research significance are described,the research status of wireless sensor network are analyzed,and then chapter of my thesis research content,the arrangement were fully explained.Then research topics related to data sampling theory,sampling theorem,quantization and quantization error of basic knowledge,wireless sensor network technology,wireless data transmission technology,wireless network technology are introduced.Is given based on the overall structure of the sensor network monitoring system and the circuit design of data acquisition part in the overall structure of the FPGA minimum system circuit,power supply circuit,USB interface circuit are introduced in detail,and node of sensor network hardware control are introduced,finally,the system uses the wireless network card are introduced and discussed in this paper.In sensor network software design part,the first of the software system for the driver design,the USB driving program and wireless network card driver design and wireless communication program design,for the design of the socket communication,makes a design of the client and server-side program.Finally on the monitoring system data acquisition capability was validated through experiments on acquisition system sampling rate control,for different signal data acquisition ability and communication system and data acquisition capability was verified.
