摘要
设计的脉象仪通过HKG-07B红外脉象传感器提取脉象信号,以TM S320VC5402作为控制核心,进行时域及频域特征提取和分类,通过USB接口可实现脉象数据的大量存储和与PC机的通信。通过对200位受试者脉象信号的采集和分类实验,表明该仪器对脉象信号的平均识别率达到87.4%,适用于临床脉象信号的诊断检测和家庭医疗保健。
The Traditional Chinese Medical Pulse Instrument uses the HKG-07B nfrared pulse sensor to get pulse signal from the body. It makes full use of the TMS320VC5402 chip to realize time-frequency domain parameters extracting, classification and identification of the pulse signal. The system can store a plenty of pulse signal and realize data communication with the PC via the USB interface. According to acquisition and classification of pulse signal experiments of 200 subjects, the results show that the recognition rate of pulse signal can reach to 87.4% It is applicable to the clinical diagnosis and detection of the pulse signal and home healthcare.
