The invention relates to the field of signal devices, in particular to a real-time concerned driving safety monitoring method and system for heart rate changes of a driver. According to the scheme, the heart rate and the respiratory rate of a driver are monitored through a non-contact laser radar; collecting face information of a current driver in real time, and determining an identity label of the driver and the corresponding vehicle distance and vehicle speed at each moment; dividing into a plurality of psychological feature groups; when a new driver is obtained, grouping is determined through accumulation of different speeds and vehicle distance information; fitting risk rate calculation is carried out on the persons in the same group, and first-level, second-level and third-level prompts are formed; and according to the first-level prompt, the second-level prompt and the third-level prompt, vibration prompt, sound prompt and character prompt are sequentially According to the scheme, data classification is carried out by combining the heart rate of the driver with the corresponding driver information based on accurate online non-contact monitoring, accident pre-judgment is carried out through drivers of the same type, warning is formed, and online monitoring alarm is carried out.

    本发明涉及信号装置领域,更具体地,涉及实时关注的驾驶员心率变化的驾驶安全监控方法及系统。该方案包括通过非接触式激光雷达监测驾驶人员的心率和呼吸频率;实时采集当前驾驶员的人脸信息,确定驾驶员身份标识及对应的每个时刻的车距和车速;划分成若干个心理特征组;获取到一个新的驾驶员时,通过不同速度和车距信息的积累,确定分组;对相同分组的人员进行拟合风险率计算,并形成一级、二级和三级提示;根据一级、二级和三级提示依次进行振动、声音和文字提示。该方案通过基于精确的在线非接触监测利用驾驶员心率结合对应的驾驶员信息,进行数据分类,并通过相同类型驾驶员进行事故预判,形成警告进行,在线监控告警。
