摘　　要：介绍了石英晶体传感器检测凝血酶原时间的基本原理,并以石英晶体为传感器研制了一套凝血酶原时间检测系统.该检测系统以单片机为控制核心,使用FPGA完成石英晶体的频率变化的测量功能,通过分析频率变化规律,计算出凝血酶原时间.检测系统具有体积小、灵敏度高、可实时检测、成本低廉等特点.The paper introduces the basic principle of QCM （Quartz Crystal Microbalance） sensor for detecting prothrombin time, and taking QCM principle for sensor has developed a set of prothrombin time test system. The detection system makes use of single chip processor as the controlling core, using FPGA to complete measurement function of quartz crystal frequency change. It calculates prothrombin time by analysis the change rules of frequency. The detection system has the characteristics of small volume, high sensitivity, real-time detection, low cost etc.
