Design Of A Remote ECG Monitor Using An Analog Front-end SOC Chip

In recent years, with the continuous improvement of quality of life, machine, theintelligent manufacturing the proportion of more and more important in the work, andpeople’s mental work more and more proportion in the total labor. High dietary levels,reduce manual labor and mental labor, poor diet, lack of physical exercise for a long time,the incidence of cardiovascular diseases every year. Since the onset of cardiovasculardisease is uncertain and sudden, so the prevention and diagnosis of cardiovasculardisease is particularly important. As people take seriously gradually to the concept ofhealth, more and more concerned about their physical and mental health, early prevention,early detection, early treatment concept gradually thorough popular feeling. If can beearly found early treatment, would greatly reduce the risk of the disease, reduce the painof the people.Detection of state of the commonly used method is through the electrocardiogrammachine measuring electrocardiogram (ECG). ECG examination to become one ofroutine inspection projects of cardiovascular disease, stomach is one of the importantbasis for clinical diagnosis, the doctor through the analysis of the changes ofelectrocardiogram curve, and then determine the condition of the heart. Usually peopleonly feel the heart is not timely, electrocardiogram test to the hospital. However, with theincrease of heart disease risk in recent years, medical equipment is relatively scarce.Coupled with the job is busy, many people take the conservative treatment method, oftenis found that the heart is unwell, have been pretty sick. Because cardiovascular eventswith a sudden, irregular, transient high and deadly, early diagnosis and timely treatmentis very important to reduce cardiovascular disease mortality, so people turn your attentionto the pre-hospital and the prevention and control, etc., such as found in the home and theprevention and control, to further reduce the incidence of sudden cardiac death,especially with China’s rapid step into aging society and pension problem of singleton female parents aggravating circumstances,pre-hospital detection and prevention ofcardiovascular disease makes more sense.For this reason, a kind of portable ECG signaldetection system is one of the more necessary. High-performance portable ECGmonitoring system of pre-hospital discovery and prevention of cardiovascular disease,and reduce the incidence of sudden cardiac death have very important significance.Based on TI company’s one of the analog front-end ADS1298SOC chip as the corechip, combined with high speed, low power consumption, strong anti-interference singleclock cycle machine microcontroller STC12LE5A60S2and ZigBee wireless network,implements a portable, low power consumption, high precision, wireless ECGmonitoring system. Patients can take advantage of the system measured ecg signals on aregular basis, and sent to doctor far away in the computer, and know my heart condition.Through the debugging of the system, the experiment results show that the systemof the ECG signal measurement is reliable, low noise, ECG signals through a serial portand ZigBee wireless network transmission to the computer, then with the help ofLabVIEW to compile applications realize the storage and display of ECG signalprocessing, etc. Lower cost of the system design, easy to carry, suitable for family andwork place such as ECG monitoring and remote diagnosis and treatment, has broadapplication prospects and potential.
