The output of the first motor 41 drives the first threaded rod 42 to rotate, which in turn drives the moving rod 9 to move inside the support frame 1. The limiting rod 43 limits the moving rod 9, and the movement of the moving rod 9 drives the detection antenna 71, the high-frequency oscillator 72, the receiving antenna 73, and the signal amplifier 74 to move. The high-frequency oscillator... Electromagnetic waves of a specific frequency are generated and then sent to a certain distance above the road surface by the detection antenna 71. The reflected electromagnetic wave signal is then received by the receiving antenna 73. The weak received signal is then amplified by the signal amplifier 74 for analysis by the subsequent data processing module. The infrared camera 62 is then fixed by the mounting bracket 61 and captures a thermal image of the road surface. The road surface condition is analyzed in conjunction with the electromagnetic wave signal. The data processor 10 calculates the actual thickness value of the corresponding point on the road surface based on the characteristics of the received electromagnetic wave signal and generates a detailed inspection report.
