The invention discloses a pedestrian/rider risk monitoring and early warning device and early warning method. A positioner collects position information and first direction information of a user and sends the position information and the first direction information to a processor; the processor compares the position information and the first direction information with preset road information; theradar sensor collects first speed information of a motor vehicle running through a user and actual distance information between the motor vehicle and the user and sends the first speed information andthe actual distance information to the processor. And the processor calculates an early warning conflict distance and a dangerous conflict distance according to the first speed information, and compares the actual distance information with the early warning conflict distance and the dangerous conflict distance. According to the invention, the walking/riding environment of the pedestrian/rider canbe monitored and reminded in real time, the pedestrian/rider can be helped to get rid of the corresponding walking/riding environment or state in time, and the injury probability is reduced.
本发明公开了一种行人/骑行者风险监测预警装置及预警方法,定位器采集使用者的位置信息和第一方向信息,并发送给处理器;处理器将位置信息和第一方向信息与预设的道路信息比对;雷达传感器采集行驶经过使用者的机动车的第一速度信息以及该机动车与使用者之间的实际距离信息,并发送给处理器;处理器根据第一速度信息计算预警冲突距离和危险冲突距离,并将实际距离信息与预警冲突距离和危险冲突距离比较。本发明能够对行人/骑行者的步行/骑行环境实现实时的监测提醒,有助于行人/骑行者及时脱离相应的步行/骑行环境或状态,减少受伤害概率。
