Description

Technical Field

[0001] The utility model relates to the technical field of marking reflection coefficient detection, in particular to a marking retroreflective coefficient detector. Background Technique

[0002] Traffic road markings are mainly drawn on the road surface, requiring strong reflection ability, distinct colors, and high reflectivity, so as to have good visibility during both day and night. A retroreflective coefficient detector is a special optical measurement device used to measure the reflective performance of road markings.

[0003] There is a Chinese utility model patent with the reference publication number of CN211061416U. It discloses a marking retroreflective coefficient detector, which relates to the technical field of road marking detection equipment. It includes a detector body. A receiving groove is opened around the detector body. A light-shielding member for shielding the periphery of the marking to be detected is arranged in the receiving groove. A cover plate for covering the opening of the receiving groove is hingedly arranged in the receiving groove. A fixing member for fixing the cover plate on the detector body is arranged on the detector body. When the detector body needs to be used, place the detector body on the marking to be detected, adjust the fixing member to open the opening of the receiving groove, and shield the periphery of the marking to be detected through the light-shielding member, reducing the light entering the marking to be detected from the gap due to the unevenness of the road surface and affecting the light intensity received by the sensor, thereby improving the accuracy of the detection result.

[0004] Due to different vehicle models, the height of the vehicle headlights from the road surface will also vary, resulting in differences in the angle between the light and the road markings. The existing retroreflective coefficient detectors cannot adjust the light angle during use and cannot simulate the headlight heights of different vehicle models. At the same time, the light intensities generated by headlights of different models are different, and the existing detectors cannot simulate headlights of different brightnesses.
