3 Overview

The measuring instrument is a measuring instrument mainly used for measuring the area of the drawing on the drawing. This instrument is widely used in land resources Land area and real estate area of surveys, cadastral surveys and management, urban and rural planning, and civil engineering and mechanics The process design is equal to the calculation work. The working principle is to use the trace tracking graphic outline to measure the area related parameters. root According to the integral principle (see Appendix A), after the operation of the mechanical computing device and using the cursor directly read the area value, or benefit The photoelectric conversion circuit converts the parameter related to the area of the measured pattern into an electrical signal, and the area value is calculated by the arithmetic circuit. According to the structure, the calculator can be divided into an image conversion type measuring instrument, a digital measuring instrument and a mechanical measuring instrument. Accurate Degree levels can be divided into I, II, and III levels. The structure diagram of the measuring instrument is shown in Figure 1, Figure 2 and Figure 3. 1-to-number conversion board; 2-manipulation handle; 3-keyboard; 4-tracking mirror; 5-Y direction guide rail; 6-X direction guide rail; 7-Y direction photoelectric encoder; 8-X direction photoelectric encoder; 9-chart conversion controller; 10-printer; 11-microcomputer Figure 1 Graph conversion calculator
