本发明公开一种基于单片机的右转车辆避让行人安全预警装置,包括单片机,并且还包括车辆速度感应器、信号检测器、四组行人感应装置和语音提示装置;在右转车道的前方上设置车辆速度感应器及语音提示系统;安全预警装置工作时,车辆速度感应器测量出车辆速度,行人速度感应装置测出任一斑马线上过街行人的方向和速度,单片机计算右转车辆刚进入某一冲突区域和出该冲突区域的时间范围之间,与过街行人刚进入某一冲突区域和出该冲突区域之间的时间范围,若两者之间有重合,语音提示器便会提醒车辆减速慢行。本装置通过及时准确的获得过街行人速度、过街的方向,提醒车辆减速慢行,使得右转车辆避让行人准确有效,降低交通事故发生率。

    The invention discloses a single chip microcomputer-based safety early warning device for a right-turn vehicle to avoid a pedestrian. The device comprises a single chip microcomputer and further comprises a vehicle speed sensor, a signal detector, four pedestrian sensing devices and a voice prompt device; the vehicle speed sensor and the voice prompt system are arranged on the front portion of a right-turn lane; and when the safety early warning device works, the vehicle speed sensor measures the vehicle speed, a pedestrian speed sensing device measures the direction and speed of any crossingpedestrian on the zebra crossing, the single chip microcomputer calculates the time range from the time when the right-turn vehicle just enters some conflict area to the time when the right-turn vehicle is out of the conflict area and the time range from the time when the crossing pedestrian just enters the conflict area to the time when the crossing pedestrian is out of the conflict area, and ifthe two time ranges overlap, the voice prompter can remind the vehicle to slow down. According to the device, by accurately obtaining the speed and the crossing direction of the crossing pedestrian, the vehicle is reminded to slow down, therefore, the right-turn vehicle can accurately and effectively avoid the pedestrian, and the traffic accident rate can be decreased.
