Design Of ECG Monitoring Mobile Phone System Based On Android

With the improvement of living standards and increasing work pressure, the incidence of heart disease is higher and higher. The common ECG has limitation and the dynamic electrocardiogram lacks real-time. On the other hand, with the development of mobile communication technology, mobile phone has become a necessary electronic product. Therefore, in order to reduce the cost of ECG detection, we can make full use of mobile phone or other mobile devices resources.This paper designs a set of dynamic ECG monitoring system based on the Android intelligent mobile phone system. The design of the system is convenient, intelligent, mobile and applicable to family, community and clinical monitoring, which plays an important role in the detection and prevention of heart disease. With the Tiny210 platform as the core, The system detects the ECG signal.For the modules, there are the ARM chip S5PV210, the Google Android4.0 system, external expansion ECG acquisition front-end, touch screen, WIFI transmission and so on. With the PC software, it realizes the functions of human ECG signals’ acquisition, storage, display, network transmission and SMS. On the server platform, the doctor can analyze and diagnose the ECG signals acquired. Testing the ECG monitoring mobile phone system after the completion of the design, the result fully meets the design requirements. It shows that the design can complete real-time monitoring, transmission and analysis ofECG signal.This paper analyzes the acquisition and processing of ECG signal, and introduces the relevant technologies. By the research of this system, the mobile phone and physiological signal detection integrates further, laying the foundation for the theory and practice of realizing the ultimate goal that a machine measures a variety of signals. The main function and innovation of the system are as follows:1、Designing and producing the ECG signal processing circuit module with a channel. The output ECG signals can be acquired by Tiny210 and also observed by the oscilloscope.2、Based on the development board of Tiny210, with the Android system and AD transfer function, acquiring, storing, displaying and transmitting the ECG signals, the software design is completed in this part.3、In the PC monitoring platform, designing the server software that the doctor uses to diagnose, the ECG signals collected in the Android client are stored, displayed, diagnosed and it sends messages through the GPRS/GSM module Sim900A.
