Study On Embedded Internet Technology And It's Application In Telemedicine

Heart disease is one of the main diseases menace human's health. Real-time ECG monitor can get ECG information of patients so that abnormal events can be discovered and measures can be taken on time. It is an efficient way to reduce death rate of heart disease. Short distance and limited monitor channels are shortcomings of the existing remote ECG monitor system. Because the burst of heart disease is occasional and paroxysmal, it is practical to bring ECG monitor from hospital to home. The main part of existing remote monitor system is a computer while the cost of sending ECG data by MODEM is high. The remote ECG monitor system studied in this article integrates embedded internet technology and remote monitor technology, it can send ECG data by internet so that it realizes real time recording and monitoring of ECG of patients at low cost and it also has some analysis function. Because the ECG data is sending by internet which is a unitive and open system, it makes the studied system has versatility, that is, it can be used at home for remote ECG monitor and act as an ideal substitute of the existing remote ECG monitor as well.The main works in this paper are listed as follows:1) Study on the basic knowledge of net and internet2) Probe into the way of realizing embedded internet technology and it's specificities3) Select the scheme for this system on the basis of study on technical literature of embedded internet technology.4) Put forward the whole design scheme for remote ECG monitor5) Design and make portable ECG data collector, including the design of ECG amplifier, ADC, wireless transmission circuit, power supply for batteries and low power waste, etc.6) Design and make wireless ECG data receiving and sending circuit based on embeddd internet module and compose the program in C language.7) Compose the application program with Delphi software, which works on the computer of monitor center. The program includes remotely link users and ECG processing, i.e. ECG data's receiving, real-time displaying, recording, replaying and analyzing.All these studies go well. The research model machine is worked out, the standard is reached, therefore good basis for the future development is well established.
