The invention relates to a road surface smoothness detection device, which relates to the technical field of road surface detection, and solves the problem that the laser detection method can be used to detect the smoothness of the road, but the laser cannot simulate the actual driving data of the wheels on the road, resulting in easy data The problem of deviation, which includes the steering part, driving part, connecting part, detection part, main control module, clock module, and lap number detection module; the main control module is preset with the highest amplitude signal, and the main control module obtains the Adjacent leveling signals and judging the amplitude; when the amplitude of the leveling signal in the line chart is greater than the highest amplitude signal, obtain the circle detection signal and time signal associated with the current leveling signal, and indicate the excess part of the line chart. The invention has the effect of performing contact detection and high data accuracy.
Description
technical field [0001] The invention relates to the technical field of road surface detection, in particular to a road surface levelness detection device. Background technique [0002] In the construction, operation and maintenance of high-grade highways, multiple quality indicators of the road need to be improved, and the requirements for the smoothness of the road surface are getting higher and higher. With the rapid progress and development of society, people's living standards are getting higher and higher, and cars have become consumer goods for the public. The smoothness of the road surface affects the service life of cars, and also plays an important role in the safety of people and cars. . [0003] In the prior art, the Chinese patent with the notification number CN101644023A is a road surface smoothness detection method. During the measurement process, an accelerometer is used to detect the relative displacement of the laser distance measuring device due to road bu...
