DI5S infrared range finder with the PC-E500 Pocket Computer Applications in the Highway Survey


About to start the computer into the machine BASIC program running, the main menu screen appears automatically power (Chinese show). 5 summarizes the main menu functions: wire, Curve, print, end. This 5 function keys corresponding to 5 PFI. PF2. PF3, PF4, PF5. Need a function to directly press the function key, in the main menu, press the button to display the wire PFI function menu, the menu shows 3 sub-functions: Adjustment (three-dimensional approximate adjustment wire), pivot (Traverse terms). Back to main (back to the main menu.) Press PF2 to display the curve of the function menu, this menu shows 5 sub-functions: angle (intersection angle. Line length). Standards (standard curve), composite (composite-shaped curve.) Oval (oval curve), back to the Lord. Press PF3 key to display the sub menu survey and design functions, showing 4 sub-functions: line (at Stake Surveying), a single point (an independent test set point). Height (in pile height measurement.) Back to the Lord. Press PF4 to display the printing sub-menu, which has 4 sub-functions: coordinate (three-dimensional wire coordinate), factor (curve elements, to claim points Stake,[link widoczny dla zalogowanych], coordinates), the pile (center line Stake, elevation), back to the Lord. The main program display notations: Br (J), Sr (J). HT (I) respectively, the level of lead from the horizontal angle, height; (J), y ∽ day (for three-dimensional wire coordinates; J as the intersection number; JD (I) for the intersection Stake; AL (for the intersection angle; R ( J) (+, a L) for the curve radius; LS (1) for the transition curve length; SL (J) for the intersection spacing; XLff.1). yL (J, 1) for the intersection point coordinates; X., y. for the test site coordinates; X.. y. as the starting point coordinate direction; X., y:, S.,. for the measuring point and the station to take the polar extreme from the measuring point, polar angle; CH Stake for the midline. Fuzhou University * 82 * 23 Volume 7, range finder at the conclusion D15s Red Pocket PC-E500 machine with the application, greatly improving the road swaddling clothes I set the precision and speed, the accuracy can meet the requirements of each grade road layout. In the actual survey and design work must be a good match between the precision and speed, to avoid unnecessary waste and impact the accuracy of the speed, the same time, bridges, tunnels and other large engineering survey to ensure precise control of its coordinate system with a unified control of the entire route, for retest the late construction is very beneficial, as long as the route to find two wire points or other elements of points, you can restore a large section of the center line, do not worry about long after the loss of some control points and can not restore the center line. The author in several secondary retest road survey and construction process, the use of DISS infrared range finder with the PC-E500 pocket-sized machine, in the case of less technical staff can quickly and accurately complete the selection lines and Center Line.
