摘要
介绍了研制的一种由TMS302VC5402芯片、TLC320AD50C、液晶模块控制器等构成的便携式动态心电采集系统。文中叙述了系统的工作原理和采用自适应差分阈值法识别和定位心电特征波的方法。此系统具有存储数据量大、噪声低、精度高、功耗低和记录时间长等优点。
The Portable dynamic state electrocardiogram collecting system is introduced by using TMS302VC5402, TLC320AD50C, liquid crystal display model, and so on. This dissertation describes the work principle of the system and uses the united algorithm based on wavelet to identify and locate the ECG characteristic waves. This system has as follows of advantags： big memory, low noise,high common mode rejection ratio,the low power consume,the long record time etc.
