Problems solved by technology
[0003] At present, there are mainly two methods to detect the performance of pavement structure: first, manual detection, which is easily affected by the technical level of technicians, personal subjective factors are greatly affected, and it is not easy to detect and analyze the internal structure of the road; second , vehicle detection, vehicle detection avoids the influence of personal subjective factors of manual detection, but it is greatly affected by the road environment, and it is easy to cause secondary damage to the road
The above two methods are currently unable to objectively and comprehensively reflect the complex changes in the mechanical response behavior of the road structure due to the combined effects of the natural environment, traffic loads and many factors during the road service process.
[0004] Although there are some relatively advanced pavement non-destructive testing equipment at present, they are all regularly tested, and diseases cannot be found and dealt with in time.

The invention provides a pavement structure monitoring system based on multi-sensor fusion, and the system comprises the following parts of a data acquisition device cluster (10) comprising at least two data acquisition devices and used for real-time acquisition of pavement condition data; and a data receiving and analysis device (30) connected to the data acquisition device cluster (10) and usedfor receiving and analyzing the pavement condition data to obtain a disease state. The pavement structure monitoring system based on multi-sensor fusion provided by the invention, by using a variety of data acquisition devices to monitor the pavement condition in real time, avoids the subjective factors of human detection, and can more accurately reflect the real pavement situation, realize timelydetection and treatment of diseases, and ensure road driving safety.
Description
technical field [0001] The invention belongs to the technical field of traffic monitoring, and in particular relates to a road surface structure monitoring system based on multi-sensor fusion. Background technique [0002] In recent years, with the rapid development of my country's economy, the total mileage of highways has increased year by year. After the asphalt pavement is opened to traffic for a period of time, under the influence of vehicle load, water factors, climate and other aspects, damage, deformation and other defects will appear one after another. Common diseases include: cracks, potholes, ruts, looseness, subsidence, and surface damage Wait. These diseases seriously affect road safety. Therefore, it is necessary to regularly detect the road surface, find out the disease in time, maintain the road surface, and ensure the driving safety of the road. [0003] At present, there are mainly two methods to detect the performance of pavement structure: first, manua...
