Abstract: The total station in the highway center line conductors and the application of measurement techniques, the Total Station use matters needing attention. Key words: Total Station Road measuring techniques 1 Total station in the wire measurement 1.1 Total Station Coordinate the advantages of Total Station can be used directly with the measuring point coordinate method, rather than polar coordinates law required, so that heavy equipment operators from the calculation of the data out. Outside the industry are now virtually no records, only a simple mind and the next point with the point of the relationship between the finishing industry for the reference period, but also do not have staff with a record of the calculation. Finishing in a time when the industry as long as the data transmission from the total station to PC2E500 calculator, or directly to the data input to a computer, after coordinate adjustment, on the computer using Auto CAD drawing software such as points, cut-off point, and calculated the angle value of each curve, the distance between the point of intersection as well as the coordinates of each pile and so. 1.2 Note and the application of state-controlled three-dimensional coordinates of points Coordinates method used before, as far as possible the country to find control points and control points of these three-dimensional coordinates, and these control points through the join test, not only can test their measurement accuracy, and error-yun Xu scope can be carried out through the adjustment of these coordinates, so that a higher measurement accuracy. 1.3 Point set should take into account the need to take the middle lane In the set point, not only should be wire line control points, that is, to point the center line should also prepare for the release, depending on the route pass conditions, 5 and higher terrain can be laid at a number of aircraft equipment, the benefits of doing so is to take the middle lane when there is a greater choice a
