The invention relates to the technical field, in particular to an optical structure of an optical rainfall sensor and a rainfall detection method, the optical structure is used for sensing rainfall on a vehicle windshield, the optical structure comprises a supporting seat, a light emitting assembly and a light receiving assembly, and the light emitting assembly and the light receiving assembly are arranged on the supporting seat. The light emitting assembly comprises a plurality of light sources and a plurality of emitting end lenses, the light receiving assembly comprises a light detector and a light guide structure, the light guide structure comprises a plurality of groups of light guide assemblies, and light beams sequentially pass through the emitting end lenses, a vehicle windshield and the light guide structure and are received by the light detector. According to the invention, a multi-channel optical path system is adopted to obtain more signals, and the signal-to-noise ratio and the detection accuracy can be improved by screening the signals through an algorithm; according to the light receiving assembly, the light guide structure is adopted to replace lens focusing in the prior art, so that the light beams are incident to the light detector from different directions, and a lens does not need to be independently designed for each channel.

    本发明涉及技术领域,具体涉及到一种光学式雨量传感器的光学结构及雨量检测方法,用于对车辆挡风玻璃进行雨量感应,包括支撑座、光发射组件和光接收组件,所述光发射组件和光接收组件设置在支撑座上,所述光发射组件包括若干光源和若干发射端透镜,所述光接收组件包括光探测器、导光结构,所述导光结构包括若干组导光组件,所述光束依次经过发射端透镜、车辆挡风玻璃、导光结构被光探测器接收。本发明采用多通道光路系统得到较多的信号,可利用算法对信号的筛选处理,提高信噪比,提高检测的准确度;本发明的光接收组件采用导光结构替代现有技术中的透镜聚焦,使得光束从不同方向入射到光探测器,无需对每一通道单独设计透镜。
