Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of road surface detection, in particular to a road surface bumping rapid intelligent detection device and method. BACKGROUND

[0002] With the increase of highway operation time, various diseases will appear on the road surface, including damage, rut, poor flatness, road or bridge head subsidence, etc. These diseases will cause the vehicle to vibrate during the driving process, and in severe cases, it can form a bumping phenomenon. Bumping seriously affects driving speed and comfort, increases the maintenance cost of bridges and highways, reduces the traffic capacity, affects driving safety and even causes traffic accidents, causing huge economic losses and affecting normal operation.

[0003] In view of the above reasons, in 2018, China formulated and promulgated the "Highway Technical Condition Evaluation Standard" (JTG 5210-2018) industry standard, and road surface bumping has become a must-check index for highway technical condition detection. The "Highway Technical Condition Standard" (JTG 5210-2018) has made a detailed description of the detection and calculation of road surface bumping. The detection vehicle obtains the road surface elevation information by sampling the profile, and calculates the longitudinal section elevation by calculating a group of data every 0.1m. The road surface longitudinal section elevation difference within 10m is calculated, and the bumping degree is judged by the range of elevation difference. The specific classification is shown in Table 1. The formulation of this method provides a new method for evaluating road surface bumping.

[0005]

[0006] Road surface bumping is a phenomenon that occurs during driving, and has a great correlation with the road surface elevation difference in the road section. Domestic and foreign researches show that road surface bumping has a great relationship with local changes in road surface roughness IRI and pothole diseases. In addition, the current standard for road surface bumping detection requires first measuring the lane line longitudinal section elevation of the road surface, calculating the elevation difference between the highest and lowest elevations within every 10m, and using it as the basis for judging road surface bumping. This method requires the use of different technologies to measure the road surface elevation difference, which has insufficient applicability in some scenarios, especially in the case of low-grade highways. At the same time, the current road surface bumping detection has high cost, complex procedure and relatively low efficiency. Therefore, establishing a convenient, rapid, efficient and low-cost bumping detection method is an urgent demand for promoting China's transportation power construction. SUMMARY
