Highway route design data are imported into control cabinet by curve table, coordinate of pile by pile table；
5th step sets up laser emitter, starts laser emitter, the confirmation to laser emitter working condition, to laser current
Dynamic station installation, correction；
6th step, paver 3D paves, and parameter is determining, and measurement takes GPS antenna to arrive to ground level, center of antenna axis horizontal direction
The distance of screed, center of antenna axis vertically arrive the distance of screed, the length of paver screed and enter data into control
In case processed；
Paver is started to operating status, opens control panel, is respectively set on the left of screed by the 7th step, solenoid valve calibration
Or the solenoid valve on right side, it is adjusted to when corresponding hydraulic cylinder starts the critical value of movement be suitable number when solenoid valve numerical value
Value；
8th step, sets up laser emitter and is corrected, and sets up laser emitter on known level control point, will flow
Station rack is located at in transmitter same level, and about 30 meters outer, measures correction to four faces of transmitter；
9th step sets up GPS reference station, a polygon control survey point is selected in the section to surfacing, by GPS reference station frame
It is located on polygon control survey point；
Control point parameter is arranged in tenth step；Creation control dot file, the title of polygon control survey point and coordinate information are input to and are led
In line traffic control dot file；
11st step is arranged GPS reference station parameter and starting GPS reference station, inputs the height and station information of GPS reference station,
The initialization of receiver is completed in the setting for completing GPS receiver signal, starts GPS Base Station；
12nd step sets up GPS rover station, and GPS flowing station host is mounted on centering rod,
13rd step corrects point, be erected at the correction of known point including GPS reference station and GPS reference station be erected at it is unknown
The correction of point；
Laser rover station is mounted on centering rod and is fixed, opens laser rover station, the thin switch of rover station hand by the 14th step,
Input laser emitter parameter, laser rover station parameter；
15th step determines paver running parameter, sets empty paving working face by the coefficient of loose laying that test section determines and paves thickness
Degree, the initial segment paver, which paves, is adjusted the height of screed and the angle at the elevation angle by paving thickness.
16th step, when spreader starting, put plank pad screed, and peace when starting that makes to pave starts to pave according to design thickness,
The screed elevation angle is beaten to the angle normally to pave, and screed height zero opens control panel, clicks starting, pave when paving
Machine enters the state that paves automatically.
