Abstract

The utility model discloses a kind of Multifunctional teaching aid, include ruler body (2), six-axle acceleration sensor (4), single-chip microcomputer (3) and LED charactrons (1), the LED charactrons (1) are embedded in ruler body (2) surface, six-axle acceleration sensor (4), single-chip microcomputer (3) are arranged on ruler body (2) inside, and the data that six-axle acceleration sensor (4) is exported are converted into angle of inclination and shown by LED charactrons (1) by single-chip microcomputer (3).The utility model has the function of ruler, level meter, dipmeter and protractor simultaneously.

Description

Multifunctional teaching aid

Technical field

The utility model is related to a kind of teaching aid, more particularly to a kind of to have ruler, level meter, dipmeter and function of angle gauge Multifunctional teaching aid.

Background technology

In mathematical education, teacher often, to carry out the drafting of angle, but draws angle using to protractor with protractor Spend speed slow, it would be desirable to have a kind of teaching aid energy Fast Drawing angle.

The content of the invention

Goal of the invention of the present utility model is to provide a kind of Multifunctional teaching aid, can simultaneously instead of ruler, level meter, incline Oblique instrument and protractor.

Goal of the invention of the present utility model is achieved through the following technical solutions：

A kind of Multifunctional teaching aid, includes ruler body 2, six-axle acceleration sensor 4, single-chip microcomputer 3 and LED charactrons 1, institute State LED charactrons 1 and be embedded in the surface of ruler body 2, six-axle acceleration sensor 4, single-chip microcomputer 3 are arranged on inside ruler body 2, The data that six-axle acceleration sensor 4 is exported are converted into angle of inclination and shown by LED charactrons 1 by single-chip microcomputer 3.

The beneficial effects of the utility model are that energy is same while having the function of ruler, level meter, dipmeter and protractor When meet the teaching needs of two subjects of mathematics and physics.

Brief description of the drawings

Fig. 1 is the structural representation of embodiment Multifunctional teaching aid；

Fig. 2 is the electrical block diagram in embodiment.

Embodiment

The utility model is described in further detail with reference to the accompanying drawings and examples.

As shown in Figure 1 and Figure 2, a kind of Multifunctional teaching aid of the present embodiment, comprising ruler body 2, six-axle acceleration sensor 4, Single-chip microcomputer 3 and LED charactrons 1, the LED charactrons 1 are embedded in the surface of ruler body 2, six-axle acceleration sensor 4, monolithic Machine 3 is arranged on inside ruler body 2, and the data that six-axle acceleration sensor 4 is exported are converted into angle of inclination and passed through by single-chip microcomputer 3 LED charactrons 1 are shown.

In the present embodiment, the model MPU6050 of six-axle acceleration sensor 4, the model Arduino of single-chip microcomputer 3 Nano3.0, uses I2C communication modes between six-axle acceleration sensor 4 and single-chip microcomputer 3.On single-chip microcomputer 3, entered using C language Edlin, the data that six-axle acceleration sensor 4 is exported calculate the radian value of angle using arc tangent formula, are finally converted into and incline Rake angle Dynamic Announce on LED charactrons.

The utility model has the function of ruler, level meter, dipmeter and protractor simultaneously, and mathematics and thing can be met simultaneously The teaching of two subjects of reason needs, and the speed of degree of painting angle is fast with traditional protractor, and table 1 is to use protractor respectively Multifunctional teaching aid one interior angle of drafting with this case is 50 °, 130 °, 50 °, the time for the rhombus that 130 ° of length of sides are 10 centimetres respectively Contrast.

Testee	The protractor used time	The Multifunctional teaching aid used time
			Teacher A	1 point 02 second	49 seconds
Teacher B	1 point 18 seconds	56 seconds
			Teacher C	1 point 29 seconds	1 point 02 second
Student A	1 point 38 seconds	52 seconds
			Student B	2 points 12 seconds	1 point 17 seconds

Table 1

In the geometric figure being made up of " straight line " and " angle " is drawn, the relatively conventional protractor of the present embodiment is (either No bottom carries ruler functions) there is obvious advantage, introduce angle, junior middle school's plane geometry and senior middle school's stereoscopic teaching in primary school In, and need in physics in the mapping on picture inclined-plane, it can find application, facilitate teacher, improve drawing efficrence.

It is understood that for those of ordinary skills, can be with technique according to the invention scheme and its hair Bright design is subject to equivalent substitution or change, and all these changes or replacement should all belong to the guarantor of appended claims of the invention Protect scope.

Claims

1. a kind of Multifunctional teaching aid, is included ruler body (2), it is characterised in that also comprising six-axle acceleration sensor (4), monolithic Machine (3) and LED charactrons (1), the LED charactrons (1) are embedded in ruler body (2) surface, six-axle acceleration sensor (4), single-chip microcomputer (3) is arranged on ruler body (2) inside, and the data that single-chip microcomputer (3) exports six-axle acceleration sensor (4) turn Angle of inclination is turned to be shown by LED charactrons (1).
