The invention discloses an acousto-optic projection early warning system and method. The system comprises a traffic management center which is used for obtaining the traffic condition information and traffic environment information of a high-speed road segment, and transmitting a control signal based on the traffic condition information and traffic environment information; and acousto-optic projection early warning equipment which is used for responding to the control signal and moving to a position corresponding to the traffic road condition information to execute acousto-optic projection early warning. According to the acousto-optic projection early warning system and method, a police car is not needed for congestion identification, potential safety hazards are avoided, identification can be carried out anytime and anywhere, and limitation of position randomness is avoided.

    本发明公开了一种声光投影预警系统及方法,所述声光投影预警系统包括:交通管理中心,用于获取高速路段的交通路况信息和交通环境信息,并基于所述交通路况信息和交通环境信息发送控制信号;以及声光投影预警设备,用于响应于所述控制信号,移动至所述交通路况信息对应的位置执行声光投影预警。该声光投影预警系统及方法无需警车来进行拥堵标识,避免了安全隐患,且能够实现随时随地进行标识,避免了位置随机性的限制。
