摘　　要：为了绘制压路机在压实过程中的碾压轨迹,实现压路机碾压轨迹的实时监控,通过对GPS接收机实时数据的解析,获得了压路机在WGS-84世界大地坐标系下的大地坐标.利用高斯投影正算法将大地坐标转换成了北京54平面坐标系下的平面坐标,进而采用平面四参数转换法得到了压路机所需的施工坐标并建立了压路机的施工平面坐标系,实现了压路机在压实过程中的实时定位,最后通过理论分析和试验来验证压路机碾压轨迹纵向和横向的定位方法.研究结果表明:采用的平面定位算法绘制出的压路机碾压轨迹图快捷、可靠、实用,可实现对压路机压实过程碾压轨迹的实时监控.To draw the track of roller compacting in the compaction process and to realize the real-time monitoring of the rolling track,by means of the analysis of real time data of GPS receiver,the geodetic coordinates of the roller in the WGS-84 world geodetic coordinate system are obtained.Using the Gauss projection positive algorithm,the geodetic coordinates are converted into plane coordinates in the 54 plane coordinate system of Beijing,then the plane four parameter conversion method is used to get the construction coordinates required by the roller and the construction plane coordinate system of the roller is set up,the real time positioning of the roller in the compaction process is realized.Finally,according to theoretical analysis and experiment,the longitudinal and lateral positioning method of roller compacting track is verified.The results show that the roller compaction trajectory plotted by the plane location algorithm is fast,reliable and practical,which can realize real-time monitoring of roller compaction trajectory during compacting process.
