Radar device and method used for real-time detection of road structure layer thickness

Abstract

The invention discloses a radar device used for real-time detection of a road structure layer thickness. The device includes a trolley. A data acquisition unit, a data processing unit and a distance sensor are installed on the trolley, wherein the data acquisition unit is controlled by the data processing unit; and the data acquisition unit includes a radar control module, a wireless module and a power supply module. The invention also discloses a method used for real-time detection of the road structure layer thickness. The radar device is high in universality, convenient to carry and capable of offering layer thickness data in a real-time manner without follow-up processing. The method not only has a plurality of advantages of high distinguishing capability, high detection precision, high detection depth and convenient operation and the like, but also realizes change from manual explanation to software automatic explanation, and from postprocessing to real-time processing of radar data through special-purpose real-time road structure layer thickness detection software.

Description

technical field [0001] The invention relates to the field of geophysical detection, in particular to a radar device and method for real-time detection of the thickness of road structure layers in the field. Background technique [0002] In recent years, my country's highway construction has achieved rapid development. According to statistics, by the end of 2012, the total mileage of my country's highways reached 4.24 million kilometers, and the mileage of high-speed traffic was 96,000 kilometers. This makes the quality inspection task of newly built roads more and more serious. The detection of the thickness of the road structure layer is the focus of all road inspections, but the original traditional road quality inspection method based on core sampling is not only low in efficiency, high in chance, poor in representativeness, but also destructive to the road. [0003] Ground Penetrating Radar (GPR) is a device that uses the difference of underground media to detect under...

Problems solved by technology

[0005] The structure of the antenna installation is more complicated and needs to be customized for different models;

[0006] People in the car cannot observe the status of the antenna in real time, and may get invalid data;

[0007] Only the collection of radar data can be completed, and the analysis results cannot be processed in real time;

[0008] The data processed after the event has a relatively large influence of human factors, and it is possible to falsify the data
