| In recent years, The size of the global family portable medical equipment market grow sharply, Portable medical equipment research and development has attracted close attention, but a portable and intelligence ECG monitoring product not much in the market. Based on the ECG monitor and some portable medical products on the basis of the current, a portable ECG intelligent detection and diagnosis system is presented in this paper. Mainly from the hardware circuit design of ECG acquisition board, ECG signal processing and ECG signal feature point extraction and intelligent diagnosis of three aspects of the system.(1) ECG signal is collected by the Electrode slice, through the design of hardware filter circuit, including the differential amplifier, high pass filtering, then product the clear ECG signal.(2) Receivedfiltering of ECG signals at the mobile via Bluetooth hardware, after using the improved plastic feedback type digital filtering technology, obtained the obvious and waveform feature points more clear visualization of ECG signals.(3) Difference threshold method and wavelet transform method is used to extract feature points in ECG signal.(4) By taking a new progressive type double BP neural network, the feature points of ECG signal multiple training study, got a can of feature points of ECG signal is intelligent diagnosis system, to achieve the basic electrical disease diagnosis ability.(5) In the current most widely used building software applications on Android mobile phone system, as the implementation ECG waveform and diagnostic information display platform, and set up a simple server, to achieve a simple cloud ECG data display.The portable ECG detection and diagnosis system designed in this paper can be used for collecting and analyzing ECG signal.Finally has carried on the system of feature points extraction algorithm performance analysis, so that the diagnosis algorithm can according to the right ECG characteristic parameters generatethe right of ECG diagnosis, has important significance to the intelligent medical construction in the future. |
