[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] In the description of the present invention, it should be understood that terms such as "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0027] See also Figure 1-4As shown, the utility model is an automatic road surface measurement robot, comprising a robot body 1. When in use, the robot body 1 is controlled to walk along the ground, and a flatness detection mechanism 2 is arranged at the front end of the robot body 1. The flatness detection mechanism 2 comprises an outer sleeve 20, an inner sleeve rod 21 is movably sleeved in the outer sleeve 20, a pair of mounting plates 22 with gaps are connected to the bottom end of the inner sleeve rod 21, and a roller 23 that rolls along the ground is rotatably installed between the two mounting plates 22 through an axis 24; a mounting block 27 is arranged in the outer sleeve 20 above the inner sleeve rod 21, and the mounting block A pressure sensor A271 is set on the bottom side of 27; a push rod 28 is set on the top of the inner sleeve rod 21, and the end of the push rod 28 is connected to a rod sleeve 282 with the top against the pressure sensor A271 through a spring A281; when the road surface is uneven, the roller 23 will jump up and down when walking along the uneven road surface, thereby driving the inner sleeve rod 21 to move up and down in the outer sleeve 20, so the pressure information collected by the pressure sensor A271 changes, the collected pressure information is digitized and a coordinate graph is drawn, with the pressure size as the Y-axis and the walking distance as the X-axis.

[0028] Specifically, Figure 4 The top of the outer sleeve 20 also passes through the robot body 1, and a top cover 11 is arranged on the top end face of the outer sleeve 20, and a convex ring 26 is arranged on the top inner wall of the outer sleeve 20, and the bottom side of the convex ring 26 is connected to the top side of the mounting block 27 through a spring B286, and the convex ring 26 is threadedly connected with an adjusting bolt 261 whose end is against the mounting block 27. With long-term use, the roller 23 will be worn. Therefore, when using it, it is necessary to control the automatic measuring robot to be on a horizontal platform before each use, and then keep the roller 23 under the action of its own gravity to rotate to the adjusting bolt 261 until the pressure signal detected by the pressure sensor A271 is 5N.

[0029] Of course, in other possible implementations, when a road surface has many potholes and is extremely uneven, when the roller 23 contacts the bottom of the pothole, the rod sleeve 282 cannot contact the pressure sensor A271. In this case, it is necessary to adjust 5N to 10N before use.

[0030] It also includes a control circuit board electrically connected to the pressure sensor A271, and a liquid crystal screen 13 for displaying pressure values ​​is arranged above the control circuit board.

[0031] It can be known that during the road surface detection process, the slope needs to be detected, that is, the robot body 1 is also provided with a slope detection mechanism electrically connected to the control circuit board; Figure 5-6The slope detection mechanism includes a cavity 10 arranged in the robot body 1, a counterweight ball 102 is suspended on the top of the cavity 10 by a suspension rope 101, and the bottom side of the cavity 10 directly below the counterweight ball 102 is connected to a movable plate 104 supporting the counterweight ball 102 by a plurality of springs C103; it also includes a detection module for detecting the distance between the movable plate 104 and the bottom side of the cavity 10. When the robot body 1 tilts, the counterweight ball 102 moves to one side along the upper surface of the movable plate 104 under the action of gravity, and then the movable plate 104 moves upward, that is, the distance between the movable plate 104 and the bottom side of the cavity 10 changes. The slope of the slope at this time can be obtained by detecting the change in the distance.

[0032] In addition, an image acquisition module is arranged at the front end of the robot body 1, so as to facilitate the control of the robot body 1 to move along the length direction of the road surface during use and avoid errors.

[0033] Method 1: The detection module is an infrared distance sensor disposed on the bottom side of the cavity 10 .

[0034] Method three, such as Figure 6-7 The detection module includes a sleeve 107 arranged on the bottom side of the movable plate 104, a conductive ring 108 is arranged on the inner wall of the sleeve 107, a guide rod 109 inserted into the sleeve 107 is arranged on the bottom side of the cavity 10, and a resistor conductive rubber strip 110 is arranged on the outer wall of the guide rod 109 along its length, and the resistor conductive rubber strip 110 and the conductive ring 108 are respectively connected to the positive and negative poles of a power supply, and an ammeter is connected to the formed circuit; the current size is detected by the ammeter to determine the connection length of the resistor conductive rubber strip 110 in the circuit, and then the distance change between the movable plate 104 and the bottom side of the cavity 10 is conveniently measured.
