TI TMS320VC5505 数字听诊器解决方案
TI 公司的数字听诊器解决方案是采用TMS320VC5505 DSP医疗开发套件来实现的.主要的元件是捕捉心肺声音的传感器,以及听诊的数字化和数字处理,以降低噪音,滤波和放大.此外还包括了心率检测和心脏缺陷检测的算法.电源和电池管理是该手提诊断设备的关键,主要的设计都采用超低功耗和高效率驱动,以延长电池寿命.本文介绍了数字听诊器总体方框图, 数字听诊器前端方框图, 增益为31的前置放大器, 一阶低通滤波器,以及TLV320AIC3254方框图和TMS320VC5505 DSP 与TLV320AIC3254间接口方框图, 数字听诊器前端板电路图和材料清单(BOM).
Digital Stethoscope Implementation on the TMS320VC5505 DSP Medical Development Kit (MDK)
The main elements of a Digital Stethoscope are the sensor unit that captures the heart and lung sounds (also known as auscultations), digitization, and digital processing of the auscultations for noise reduction, filtering and amplification. Algorithms for heart rate detection and heart defect detection may also be included.
