Program Design And Realization Of Computer Aided Measurement Traverse

This paper is mainly about the adjustment of measurement problems, to traverse and vertical quasi of distance control measurement problems, according to coordinate, vertical quasi distance formula, through the establishment of a database to establish project data, work in the input, the known data modification. Adjustment is to input the known and unknown, end points, adjustment calculation of wire, leveling data, and the results are displayed on the screen, if the check is correct, write in the database can be calculated after wire drawing, also can be the result of check operations.In this paper, using Visual basic language, developed a computer aided traverse survey program, the program is a measurement of feasible adjustment calculation tools, to realize the automatic calculation of wire and horizontal alignment adjustment, the software has lower redundancy, high calculation accuracy, fast and flexible, the characteristics for the huge amount of information processing higher capacity, can save a lot of time, also can be because of the human operation into the error or mistake is minimized, thereby to complete automation, intelligent processing of measurement data. The software implementation of the multi form design, build build Access database, available for users of the data in the database to add, delete and modify, and change the display on the screen data; realize the radian to angle, angle to a mutual transformation radian; on the wire, horizontal alignment measurement known data, input output data; the adjustment calculation of wire, horizontal alignment measurement data; the adjustment after the data view and traverse coordinate for graphics rendering.Currently, the software has been widely used in the actual mapping work. The practice shows that the design of the software is very practical, simple and accurate operation, which greatly enhance the technical level and efficiency of data processing. It also advances digital technology and the development of wire measurement modernization as well as palying great role in the operation and inspection of the data.
