[Abstract]:With the development of society, people begin to pay more and more attention to their own health. All kinds of elderly patients, chronic diseases and emergency patients need a kind of platform which can continuously monitor the important physiological parameters of patients and communicate between doctors and patients anytime and anywhere. With the development of modern communication technology, especially the popularity of mobile communication and Internet technology, remote ECG monitoring has begun to show more and more powerful attraction. The ECG monitoring system which is oriented to families and individuals and can communicate and communicate with hospitals in time is of great practical significance. In this paper, a remote real-time ECG detection system based on GPRS is studied and designed on the basis of laboratory project. The system can transmit the user information of ECG monitoring terminal equipment and the ECG data collected in real time to the monitoring center workstation through the GPRS network, and analyze and manage the collected ECG data through the monitoring center. Assist the physician to monitor and analyze the current state of the patient's heart function. The main work accomplished in this paper is as follows: Firstly, this paper introduces the research background and significance of remote ECG monitoring, and summarizes the current situation of remote ECG monitoring. The overall framework and module of the system are given. Secondly, the realization principle of short message transmission and wireless data transmission using GPRS is analyzed, and the coding format of wireless transmission of ECG data is established to complete wireless transmission of user data and ECG waveform data. The reliable data communication between user terminal and monitoring center is realized. Third, complete the design and development of the monitoring center workstation. The realization of four basic modules of monitoring center: data transceiver, user interface, ECG automatic analysis and ECG data management. Fourthly, the received ECG data are de-noised and feature extracted by wavelet analysis. The wavelet basis of denoising is based on Daubechies wavelet. The wavelet coefficients of the scale of noise are de-noised by soft threshold through wavelet decomposition and reconstruction method, and the noise and drift are removed. The characteristic of ECG waveform is extracted, and the initial position of R wave and Q wave S wave and P wave T wave are located by Mexican-Hat wavelet decomposition with different scales. The results of MIT-BIH test show that the algorithm is effective and meets the design requirements. Finally, the work done in this paper is systematically summarized, and the next research direction is pointed out.
