Problems solved by technology

If such transportation conditions are completely driven and controlled manually, the labor intensity is very high, and it is difficult to ensure the safety of the operation, so that the beam transport vehicle can walk on the center line of the prefabricated beam.
And because...

Embodiment Construction

[0024] As shown in FIG. 2 , the automatic driving control system of a large construction vehicle of the present invention includes marking lines, a camera system installed on the vehicle and a motion control system. The camera system includes a camera, a computer, a light source, and a display (refer to FIG. 5 ). The automatic control system is a PLC control system.

[0025] The large engineering vehicle automatic driving control method of the present invention is:

[0026] As shown in Figure 3, the marking line 1 is drawn on the road surface 4 along the road direction in advance, as the vehicle (beam transport vehicle 2 in this embodiment) driving track; As shown in Figure 4, there are two cameras 3, respectively Be contained in the headstock and the tailpiece of beam transport vehicle 2. When the automatic driving is started, the running speed of the beam transport vehicle will automatically run at a constant speed according to the automatic driving speed set by the PLC co...

Abstract

The utility model discloses a self-steering control mode and system for the large-sized engineering truck. The tag line is made as the vehicle moving track along the road; the vehicle is equipped with a kinetic control system and a camera chain; the kinetic control system controls the moving forward of the vehicle. In the course of moving forward, the tag line is shot by the video camera in the camera chain, so that the computer in the camera chain can make the analysis according to the tag line-related real time video image, so as to work out the vehicle bias data which are transferred to the kinetic control system. As per the bias data, the kinetic control system can follow the existing moving direction or correct the moving direction. The method achieves the self-steering and the automatic guide of the large-sized engineering truck, so as to improve the work efficiency for the large-sized cargo transportation and the reliability in the transportation process.

Description

technical field [0001] The invention relates to the automatic control technology of equipment, in particular to a large engineering vehicle automatic driving control method and system. Background technique [0002] Now in the construction process of high-speed railway bridges, centralized prefabrication of beam yards, transportation of large-scale engineering vehicles such as beam trucks (as shown in Figure 1), and construction methods of large-tonnage bridge erecting machines or integrated transport and frame erecting machines have been adopted. The driving of the beam transport vehicle is a simple and repetitive work that requires high control precision, and most of the driving routes run on the prefabricated beams that have been erected. During the docking process of the large-tonnage beam transport vehicle and the bridge erecting machine, it is necessary to keep the precise alignment of the beam transport vehicle and the bridge erecting machine, and the vehicle is requir...
