The invention provides a road directivity safety early warning device without noise interference, which relates to the technical field of traffic facilities and comprises a shell, a data processing unit and a concrete ground, a base is installed at the bottom of the machine shell, a top plate is fixedly arranged at the top of the machine shell, a snapshot mechanism is installed in the machine shell, an ultrasonic assembly is installed in the machine shell and located below the snapshot mechanism, and a speed measuring mechanism is installed in the machine shell and located below the ultrasonic assembly. A display screen is installed in the outer wall of the machine shell in an embedded mode. According to the scheme, vehicle information is finally confirmed through a radar testing technology and an image recognition technology, sound and image information is accurately transmitted through an LED screen and a loudspeaker, meanwhile, sound is accurately projected into a designated area where a vehicle is located through an ultrasonic directional sound transmission technology, prompt voice containing the designated vehicle information is broadcasted, and the effect of prompting the vehicle is achieved. Due to the characteristic of small-angle directivity of audio of the ultrasonic directional sound transmission technology, the sound is prevented from interfering other vehicles or environments.
本发明提供一种无噪音干扰的道路指向性安全预警装置,涉及交通设施技术领域,包括机壳、数据处理单元和混凝土地面;所述机壳的底部安装有底座,所述机壳的顶部固设有顶板,所述机壳的内部安装有抓拍机构,所述机壳的内部且位于抓拍机构的下方安装有超声波总成,所述机壳的内部且位于超声波总成的下方安装有测速机构;所述机壳的外壁内嵌安装有显示屏。该方案最终实现通过雷达测试技术、图像识别技术手段确认车辆信息,并通过LED屏、扬声器准确传达声图讯息,同时采用超声波定向传音技术将声音准确投放至车辆所在指定区域内,播报包含指定车辆信息的提示语音,因超声波定向传音技术音频小角度指向性的特征,防止该声音对其他车辆或环境造成干扰。
