[0002] With the development of my country's economy and modernization, highways have become an important means of transportation and play a positive role in my country's economic development. However, due to the influence of the natural environment and external traffic loads, road structures will produce various types of roads. Diseases affect the normal traffic flow, and may endanger driving safety in severe cases. Therefore, scientific and effective road monitoring devices and data processing methods should be used to monitor and deal with the structural performance of roads, so as to detect possible road structure diseases in time and Take effective maintenance measures

[0003] At present, the challenges faced by traditional road structure performance testing methods mainly include four aspects: "poor result accuracy, low detection efficiency, single acquisition parameters, and short equipment life cycle". Specifically, there are the following problems:

[0004] First, the traditional road structure detection method is mostly a method of emitting electromagnetic waves into the road structure. The characteristics of the road structure are calculated by analyzing the waveform change of the electromagnetic wave during the propagation process. This method cannot directly obtain the internal performance parameters of the road structure; In addition, general data processing methods often only consider the influence of one of the parameters on the performance of road structures, often ignoring other factors, resulting in low accuracy of detection results;

[0005] Second, the efficiency of the detection method is low. The traditional additional detection methods are mostly manual fixed-point detection, which can only be limited to a certain period of time or a certain range, and cannot realize real-time and comprehensive monitoring of the road structure;

[0006] Third, the general detection method often only obtains a specific parameter that reflects the performance of the road structure, and cannot comprehensively and accurately obtain information that affects the road structure, resulting in the inability to evaluate the road structure condition more accurately;

[0007] Fourth, most of the monitoring methods often adopt the method of wired transmission, resulting in a high damage rate and easy to adversely affect road performance such as the strength of the road structure itself.
