The invention discloses a vehicle distance and vehicle speed real-time monitoring and early warning system, relates to the technical field of vehicle early warning, and is used for solving the problems that the current vehicle distance monitoring and early warning adopt direct setting of speed and vehicle distance to limit and trigger early warning, so that intelligent vehicle distance and vehicle speed monitoring and early warning triggering cannot be performed according to the actual condition of a road vehicle; and the early warning is not accurate and not timely. Comprising a data acquisition unit, a road condition analysis unit, a vehicle analysis unit and a feedback unit, the threshold value is analyzed and set by analyzing the relation among the traffic flow, the vehicle density and the vehicle flow speed to determine the interval of the vehicle flow speed, the threshold value is intelligently and reasonably set to limit the vehicle speed, whether the vehicle speed meets the current road condition or not is judged accordingly, and intelligent setting of the speed limit of the vehicle speed according to the road condition is achieved. A high traffic flow is kept under the condition that the speed limit of the vehicle is more reasonable; and meanwhile, early warning and feedback are carried out on vehicles with abnormal vehicle distances and vehicle speeds, so that monitoring and prompting measures on the vehicles with abnormal vehicle distances and vehicle speeds are realized.
本发明公开了一种车距车速实时监测预警系统,涉及车辆预警技术领域,用于解决目前的车距监测预警采用直接设置速度和车距进行限制并触发预警,存在无法根据道路车实际状况进行智能车距车速的监测和触发预警,导致预警不准确和不及时的问题;包括数据采集单元、路况分析单元、车辆分析单元和反馈单;通过分析车流量、车密度和车流速三者之间的关系来分析设置阈值来确定车流速的区间,智能合理的设置阈值来限制车速度,并据此判断车速是否符合当前的道路情况,实现根据道路情况智能设置车辆速度的限速,使得车辆的限速更加合理的情况下保持较高的车流量;同时对车距车速异常的车辆进行预警和反馈,实现对车距车异常车辆的监控和提示措施。
