Embodiment 1

[0052] An embodiment of an intelligent pavement crack repair system of the present invention is basically as attached figure 1 shown, including:

[0053] The two-dimensional module is used to collect two-dimensional images of the road surface in real time;

[0054] 3D module for collecting 3D data of fractures;

[0055] The identification module is used to analyze the two-dimensional image of the road surface, determine whether there are cracks in the road surface, and determine the location information of the cracks when there are cracks in the road surface;

[0056] The control module is used to send the control signal for collecting the three-dimensional data of the crack and the control signal for reducing the vehicle speed when there are cracks on the road surface; send the control signal for slotting, send the control signal for dust removal, and send the control signal for repair;

[0057] The stereo module is used to establish a fracture stereo model according to the...

Embodiment 2

[0071] The only difference from Embodiment 1 is that the car cavity 7 of B is stored with emery, which is used to enhance the skid resistance of the repaired cracks. If the skid resistance of the repaired road surface does not meet the requirements, emery will flow out from the discharge port 8 of the B vehicle cavity and the valve 9 of the B vehicle cavity, and be laid on the road surface to improve the skid resistance coefficient.

Embodiment 3

[0073] The only difference from Embodiment 2 is that there are two two-dimensional scanning probes, including probe A and probe B, which are installed on the head of the vehicle; probe A and probe B are located on the same straight line and in the same direction as the vehicle is moving forward. In this embodiment, the deflection angles of probe A and probe B can vary between 30 and 60 degrees, and the deflection angle refers to the angle between the light emitted by the probe and the straight line perpendicular to the road surface. The probe deflects toward the front of the vehicle, deflecting angle is positive.

[0074] Initially, the deflection angles of probe A and probe B are both 30 degrees. When the vehicle is moving forward, the vehicle's driving speed is detected in real time, and the detected vehicle's driving speed is sent to the server. If the driving speed of the vehicle is between 0 and 30km / h, the server sends a signal to the control system so that the deflectio...

Abstract

The invention relates to the technical field of road maintenance, and in particular relates to an intelligent pavement crack repairing system. The system comprises a two-dimensional module for acquiring a pavement two-dimensional image in real time, a three-dimensional module which is used for collecting crack three-dimensional data, a recognition module which is used for analyzing the two-dimensional image of the pavement and judging whether the pavement has cracks or not, a control module which is used for sending a control signal when the pavement has cracks, a three-dimensional module which is used for establishing a crack three-dimensional model according to the crack three-dimensional data, a disposal module which is used for conducting groove expanding and other treatment on the pavement cracks according to the result fed back by pavement crack recognition, a dust removal module which is used for cleaning the grooved pavement according to a dust removal control signal, and a repairing module which is used for repairing the cracks according to a repair control signal. The problems of high labor cost, low efficiency, long consumed time, low intelligent degree, poor repair durability and the like of current pavement crack repair in the prior art are solved, and the traffic safety in the road maintenance process is also improved.

Description

technical field [0001] The invention relates to the technical field of road maintenance, in particular to an intelligent pavement crack repair system. Background technique [0002] At present, pavement cracks are mainly repaired manually, that is, the cracks are manually identified and marked, and the appropriate method is selected according to the crack type to repair the cracks. This method is inefficient, time-consuming, and low in intelligence, which cannot meet the current rapidly growing maintenance. Quantity requirements and quality requirements. With the increase in the intelligence of highway traffic, intelligent scanning and recognition technology is constantly being applied to automatic repair operations. [0003] For example, the document CN102644234A discloses an automatic repair vehicle for cracks, including: a car body; a road surface scanning mechanism for capturing real-time road surface conditions; a crack identification module for analyzing and identifyin...
