摘　　要：驾驶员疲劳驾驶是引发道路交通事故的主要原因。依据心冲击图(BCG)、呼吸等生理参数客观监测行车过程中的驾驶员疲劳状态成为了研究热点。针对传统生理信号采集需用复杂电极和导联线接触人体的弊端,基于偏聚氟乙烯(PVDF)压电薄膜的正压电特性,设计了一种非接触式汽车驾驶员心电监测系统。构建了可靠的小信号调理和电压抬升电路,研究了心冲击图和呼吸信号的分离提取算法;计算出心率和呼吸率并通过低功耗蓝牙通信发送到手机软件(APP)进行显示。实验表明,系统能实时可靠的监测行车中驾驶员的心率和呼吸率,提高了汽车行驶的主动安全性。It is a research hotspot to objectively monitor the driver fatigue state during driving according to physiological parameters such as ballistocardiagram(BCG)and respiration,due to fatigue driving for vehicle driver is the main cause of road traffic accidents.A non-contact(ECG)monitoring system for vehicle drivers is designed based on the positive piezoelectric characteristic of(PVDF)piezoelectric film,aiming at the disadvantages of traditional physiological signal collection using complex electrodes and lead wires to contact the human body.Construct reliable small signal conditioning and voltage boost circuit,the separation algorithm of BCG and respiratory signal,calculate heart rate and respiration rate and sent to the mobile phone application(APP)for display through bluetooth low energy communication were studed.Experiments show that the system can reliably monitor the heart rate and respiration rate of driver in real time and improve the active safety of vehicle.
