摘　　要：为了改进当前脉象模拟技术一致性较差,未考虑中医师的取脉位置和应指压力等缺点,设计了新型脉象发生器和仿生手,利用多传感器信息融合技术智能检测中医师的取脉位置和应指压力,实现人体26种临床脉象和被试者脉象的准确复放。经过实验验证,该系统复放波形、脉图与输入波形间的相关系数R xy均大于0.85,具有显著相关性;脉象主要特征值误差在5%以内。经多名老中医盲测,一致认为本复放系统可应用于中医脉诊课堂教学测试、职业中医师培训考核、中医脉诊研究等领域。In order to improve the shortcoming of current pulse simulation method, the poor consistency and lack of considering the pulse position and the pressure, this paper designs a new type of pulse generator and bionic hand. Based on multi-sensor data fusion technology, this system automatically detects the pulse position and the pressure of TCM doctors and has successfully replayed 26 kinds of human pulse and collected pulse. With experimental verification, all the correlation coefficients between replayed and the input waveforms are greater than 0.85, with a significant correlation;the error between the main characteristics is less than 5%. Through several TCM doctors blindly testing, this system can be used to test of TCM pulse-taking,train and assess TCM practitioners, research on TCM pulse diagnosis.
