The professional computer placed on the paver controls the automatic tracking and measuring robot that is set up freely or erected on the control point and completes the orientation through the wireless data transmission station, and acquires and collects both sides of the paver screed in real time (paver screed The traction boom) fixedly placed precision prism coordinates. A measuring robot is placed on the left and right sides of the paver at the work site to obtain the three-dimensional coordinate position data of both ends of the screed in real time respectively, and through the digital map information of the construction line pre-stored in the data processing center, the movements on both sides of the mold on the system are calculated in real time Requirement information (values include elevation deviation on the left and right sides of the sliding model, lateral line deviation, transverse slope deviation, etc.). The data is comprehensively processed by the data processing center of the 3D control system on the paver and then transmitted to the controller. The controller generates the corresponding proportional pulse driving signal by setting (matching the control mode between the controller and the paver during installation and debugging) Debugging, select the corresponding paver solenoid valve control mode and parameters), drive the paver leveling hydraulic cylinder through the hydraulic valve, so that the paver screed can be adjusted accordingly, with the continuous movement of the screed, the prism and drive signal will also Continuous adjustment, the greater the elevation difference, the greater the driving signal, the faster or more continuous the adjustment speed. The adjustment of the screed also causes the slope and elevation changes of the loose layer of the paved road to meet the elevation and slope requirements set in advance by the system. In this way, the large cycle data of the mechanical action is completed. In addition, the ranging sensor between the body of the paver and the traction arm (at the position slightly in front of the floating oil cylinder) monitors the paving thickness adjustment process, and transmits it to the computer in real time to form small cycle data. The system combines big data and small The two-way cycle control of data guides the mechanical direction of the paver and the change of the 3D posture of the iron mold, making the process control more precise, realizing the required road surface flatness and the structural requirements of other construction objects, and meeting the transformation from paving design to construction realization. The whole process.
