[0047] (1) During installation, the mounting bracket 1 is installed on the back of the detection vehicle using bolts, etc., and attention is paid to the installation height: so that the spring 506 is in a semi-compressed state to avoid failing to pop out and thus failing to detect potholes, or failing to retract and thus failing to detect road bumps. (2) When encountering potholes or bumps on the road, the floating pile 503 in a certain detection unit 5 moves up and down, causing the distance sensor 507 to receive different signals for data acquisition, and at this time the road position information is determined by the encoder a5032 for travel determination. (3) When in the like Figure 3 When the road surface is tilted, both the fixed frame 1 and the detection vehicle are tilted to the right. However, due to the weight of the counterweight 4 and the influence of the center of gravity at the center position of the vertical frame 3, the vertical frame 3 and the components below it are in a horizontal state. When the floating piles 503 in each detection unit 5 come into contact with the tilted ground, the extension distance is different. With the data held for a long time, it can be determined that the road surface is tilted and the tilt angle can be calculated. (4) Due to the tilt of the vertical frame 3, the fixed shaft 203 rotates in a disguised manner. At this time, the data collected by the encoder b307 is also the tilt angle data, which is transmitted to the host computer and combined with the data in step (3) for dual and comprehensive judgment.

Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
