Abstract:

In order to enrich the product categories and function of the dynamic electrocardiogram,a new type of dynamic electrocardiogram product based on ARM(Advanced RISC Machines)Cortex-M3 is developed.The system hardware consists a processor minimum system,bioelectricity amplification module,storage module,LCD（Liquid Crstal Display)  and touch screen module,high speed USB interface and the power module.For the system software,the platform was build based on CooCox CoOS embedded real-time operating system, the file system and USB middleware.The man-machine interface is realized by transplanting uC/GUI.The experiment results showed that the system could be used to control ECG signal collection,great capacity data storage and high-speed upload.The graphical user interface and real time waveform display are the innovative points.
