摘　　要：本系统设计通过方向盘加载压电式传感器测定驾驶员心率,利用单片机处理实时数据,当测量数值与标准值之间差距过大时,通过发出声响使驾驶员警醒。相比较PERCLOS等测定疲劳的方法,本系统具有方法简单、经济性高、适用性强、性价比高等特点。The design of the system tests driver＇s heart rate via piezoelectric transducer which is loaded by the steering wheel of an automobile. The system uses single chip microcomputer to deal with real-time data. When the gap between the measured value and the standard value is too large, it will make a sound to alert the driver. Compared with PERCLOS and other the methods of testing fatigue, this system is simpler, more economic, more practical, and more cost-effective.
