The Design of Ecg Signal Generator Based on ARM9

This topic design of ecg signal simulation generator, through digital signal reduction by ecg original analog signals to simulate human body, or send other analog signal to ecg products, achieve the purpose of test ecg products. Ecg simulation signal generator forms by the hardware and software of upper and lower level computer, the task of PC is sending ecg data down to machine work, the task of lower machine is responsible for receiving and storage ecg data. PC is based on Visual c + + integrated environment of software system. through Visual c + + complete program design. Lower place machine is based on embedded system by the ARM9, ARM9 core board, serial ports, Ethernet, DAC, LCD, input/output, and other plug-ins interface component. The whole system realizes several different format of ecg signal data of transmission through serial and net, storage and analog output and polarization voltage function, and can also produce sine wave and square-wave and normal ecg wave can be used waveform, such as amplitude, frequency of regulation.
