Abstract

The invention discloses a road flatness detection device, which is arranged on a plurality of test vehicles, comprises a shell and a main control board arranged in the shell, and is characterized in that the main control board is electrically connected with an acceleration sensor configured to detect a vibration amplitude change value generated by pavement fluctuation; a plurality of laser sensorstransversely arranged and configured to emit test laser and receive reflected light reflected by the road surface to obtain image information formed by a plurality of paths of reflected light; an image processing module configured to obtain the height of a gap between the image processing module and a reference surface according to the image information; a data acquisition and processing module;a processor configured to obtain flatness information of the road surface according to the vibration amplitude change value subjected to analog-to-digital conversion and the position information of the test vehicle; and a communication module.

Description

technical field [0001] The invention relates to a measuring device, in particular to a road smoothness detection device. Background technique [0002] Road surface roughness (Road Surface Roughness) refers to the deviation value of the unevenness in the longitudinal direction of the road surface. Pavement flatness is an important index in pavement evaluation and pavement construction acceptance, which mainly reflects the flatness of the profile curve of the pavement longitudinal section. When the profile curve of the pavement profile is relatively smooth, it means that the road surface is relatively flat, or the flatness is relatively good, otherwise it means that the flatness is relatively poor. A good pavement requires good evenness of the pavement. At present, there are generally three methods for measuring the flatness of the road surface: 1) the fixed-length ruler method, that is, a straight ruler of a specified length is placed on the road surface, and the gap betwee...
