Ecg Monitoring System Based On Arm Research And Implementation

Nowadays angiocardiopathy has been one of disease that threaten human's life and health.ECG monitor can trace patient's electrocardiosignal continually, which would be an efficient method in clinical monitoring and diagnosis of heart disease. Whether ECG monitor system can trace all the electrocardiosignal on time correctly when all the monitored signal changed abnormally, it would affect doctor's diagnose to the patient correctly and the continual treatment. So design and research of high-reliable dynamic ECG monitor system can make great significance in clinical medicine.And the development of technology in the fields of software and hardware of computer science, micro-electronic and embedded, can support very well for studying the such device.This paper designs a proper detection circuit in this paper with appropriate computer chip selected, and the paper, based on the analysis of electrocardiosignal, focus on weakness of electrocardiosignal, mass of disturbance signal.Designing of this circuit includes analysis and design of amplifier,high-pass filter and low-pass filter, which makes weak electrocardiosignal access the circuit in mass of electrical noise.Then filter accurate wave, and transmit to A/D module.During the procedure of signal transforming, the original signal can be recognized by ARM processor.This paper choose samsung s3c2440 processor to analysis the collected signal, and display on screen in real-time, and save the electrocardiosignal data in SD storage, for fear that doctor analysis by himself to improve the accurate rate in detecting patient's heart disease.Designing alarm module, by calculating rhythm of the heart to detect whether a patient's heartbeat is normal, can makes patient get treatment without delay.In software module, this paper choose appropriate bootloader and embedded linux kernel to transplant.and this paper analysises specific implement of A/D transform SD storage and LCD.
