Description

A kind of novel angulation surveying and mapping tool

Technical field

The utility model belongs to electronic science and technology field, relates to a kind of novel angulation surveying and mapping tool.

Background technology

In engineer operation and mechanical drawing, often need to survey and draw various angle, the most frequently used survey instrument is protractor, and in the conventional technology, protractor is typically designed to a semicircular plate, places and portrayed angle mark outside the semicircle of plate.When utilizing this kind of protractor to draw the angle of required angle, first draw straight line, make the end points at angle, again the center of circle of protractor is overlapped with the endpoint location at angle, a point is made afterwards outer the placing of protractor, and then this point is connected into straight line with the end points at angle, finally just complete the technique of painting at angle, utilize this kind of protractor to carry out the technique of painting at angle, reduce the efficiency of use.

Summary of the invention

The purpose of this utility model is to provide a kind of novel angulation surveying and mapping tool, replaces the angulation surveying and mapping tool that traditional graduated scale is novel, makes the measurement of Plane Angle convenient, quick, accurate with drafting.

The technical scheme that the utility model adopts is, a kind of novel angulation surveying and mapping tool, comprise measurement plate, measure on plate panel and be provided with rotational potentiometer, rotational potentiometer is other be provided with for treat angle measurement play the angle plotting staff that initial line overlaps, rotational potentiometer is fixedly connected with the miniature laser pen that can rotate together with rotational potentiometer, the laser that miniature laser pen is launched is used for and treats that the whole limit of angle measurement overlaps, rotational potentiometer signal output part is connected with CPU module, CPU module is connected with LCDs, CPU module is treated the number of degrees of angle measurement according to the electric current and voltage value calculating of the rotational potentiometer received and is shown by LCDs.

Further, angle plotting staff comprises the aided ruler and an initial line scale that are parallel to each other, the measurement limit of aided ruler and rotational potentiometer central point are on same straight line, play initial line scale and be positioned at the top of aided ruler, rise initial line scale and aided ruler all for treat that the initial limit of angle measurement overlaps.

Further, CPU module is provided with function button, and function button comprises reset key, plays initial line selection key and whole limit selection key.

The beneficial effects of the utility model are, can accurately measure or draw the angle in random two-dimensional plane, and its numerical value is recorded in display, use simple, measure fast, precision is high, can 360 ° to measure measurement ranges wide, simultaneously small and exquisite portable.

In figure, 1. laser pen, 2. turn knob potentiometer, 3. initial line scale, 4. aided ruler, 5. display screen, 6.CPU module, 7. function button, 8. measure plate.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.

The utility model provides a kind of novel angulation surveying and mapping tool, as Fig. 1, shown in Fig. 2, comprise and measure plate 8 i.e. blade, measure on plate 8 panel and be provided with rotational potentiometer 2, rotational potentiometer 2 is other be provided with for treat angle measurement play the angle plotting staff that initial line overlaps, the right side that angle plotting staff is positioned at rotational potentiometer 2 for treat that the initial line that rises of angle measurement overlaps, rotational potentiometer 2 is fixedly connected with the miniature laser pen 1 that can rotate together with rotational potentiometer 2, the laser that miniature laser pen 1 is launched is used for and treats that the whole limit of angle measurement overlaps, the knob of turn knob potentiometer 2 and miniature laser pen 1 or laser pen are fixed together, when miniature laser pen 1 or laser pen rotate together with the knob of turn knob potentiometer, the whole limit of the thin direct light line that miniature laser pen 1 or laser pen send and angle to be measured or wait that the whole limit of drawing angle overlaps, rotational potentiometer 2 signal output part is connected with CPU module 6, CPU module 6 is the integrated electronic modules with AD digital-to-analog conversion and simple data processing capacity, the minimum systematic module of such as Atmega16, CPU module 6 is connected with LCDs 5, CPU module 6 is treated the number of degrees of angle measurement according to the electric current and voltage value calculating of the rotational potentiometer 2 received and is shown by LCDs 5, measurement is when angle measurement, rotate thin direct light line that miniature laser pen 1 makes it send and treat that angle measurement limit at end overlaps, the electric current and voltage value of rotating generation with miniature laser pen 1 is sent to integrated electronic modules i.e. CPU module 6 by rotational potentiometer 2, the electric current and voltage value that integrated electronic modules receives the rotational potentiometer 2 rotated with miniature laser pen 1 draws through AD conversion computing the angle for the treatment of angle measurement and is presented in LCDs 5 by angle value.

Angle plotting staff comprises the aided ruler 4 and an initial line scale 3 that are parallel to each other, the measurement limit of aided ruler 4 and rotational potentiometer 2 central point are on same straight line, play the top that initial line scale 3 is positioned at aided ruler 4, rise initial line scale 3 and aided ruler 4 all for treat that the initial limit of angle measurement overlaps, initial line scale 3 has been provided with along measuring the plate 8 i.e. upper horizontal edge of blade, only just measurement of angle need can be carried out by measuring horizontal sides on plate 8 with until rising after initial line overlaps of angle measurement when needing to measure, due to miniature laser pen 1 have its length and central point with rise initial line scale 3 not on same straight line, when carrying out measurement of angle when measuring angle is less, at this moment can use aided ruler 4 and treat that the initial line of angle measurement overlaps and carry out small angle measurement.

CPU module 6 is provided with function button 7, and function button 7 comprises reset key, plays initial line selection key and whole limit selection key, can carry out function selection according to use operation.

A kind of novel angulation surveying and mapping tool structure of the utility model is advanced, easy and simple to handle, measure fast, accurately, can accurately measure or draw the angle in random two-dimensional plane, and its numerical value is recorded in display, simultaneously can 360 ° of measurements, measurement range is wide, small and exquisite portable, the non-contact measurement of angle can be realized.
