此程序实现了将GPS设备中采集的txt文件格式数据转成了UPT格式，进而转成DXF、SHP等格式！-This program implements the txt file format data collected in the GPS device will be turned into UPT format, and then converted to the format of DXF, SHP,

DXF轨迹图转G代码，有 直线，圆，圆弧，样条曲线，优化多段线，多段线。与下位机串口通讯！无法编译，是因为要先注册mscomm控件-DXF trajectories turn the G-code, line, circle, arc, spline curves to optimize the polyline, polyline. With lower serial communications! Not compile because the first registered mscomm
