Abstract
A kind of bead of abacus learning machine, it is characterised in that described bead has cavity and endoporus, and the endoporus of bead is square, oval or polygonal；The endoporus of bead is provided with magnetic bodies.
Description
Technical field
The present invention relates to teaching field, more particularly to a kind of bead of abacus learning machine.
Background technology
Calculating is the intellectual development of mathematics, and life, science and techniques of defence, the industry manufacture of the mankind all be unable to do without and calculated, and calculating is
Gathered before physics and chemistry, without good computing capability, cannot propagate into the technical research in each field.
Abacus is China's calculating cultural tradition of 5,000 years, if being all popular in calculator at present, China's educational system is still
Abacus teaching is paid much attention to.Abacus can provide the visual representation of numeral, student can be encouraged to use one's brains, this visual representation can make
The concept that study of numbers system and arithmetic implement behind becomes easier to, such as：Such as decimal point, place value, carry, borrow it is general
Read the physical manipulations that is converted to and can be observed on abacus from abstract concept.Recognizing that abacus can above carry in Mathematics Concept Teaching
After benefit, some schools use abacus in based algorithm class.
The conventional teaching of rechoning by the abacus school relies on professional teachers, to check the progress of student, instructor view everyone to bead
Operation, although check obtained by final result be typically not enough to determine whether the student correctly implements computing, training
Early stage, it is necessary to which the intensive intervention of teacher, limits and while can be taught number of students amount.
As student improves, implement to practise by saying the numeral that on abacus will implement and computing, then check him
Obtained correct result, although these exercises can improve the speed of student, when the errors have occurred, done wrong on student
What and cause the mistake, only fed back on a small quantity.Therefore, the technical staff in field not yet has found a kind of by abacus and calculating
Device combination application, it can provide correct option with help on-line student.
The content of the invention
The present invention is solves the defects of prior art, there is provided a kind of bead of endoporus installation magnetic bodies, applied to
The abacus of calculator, bead and the Hall on pearl bar of magnetic bodies form position sensing, the study of student can be made to calculate number
According to being shown in calculator, and checked with calculator data, realize that student reviews one's lessons error correction.
A kind of bead of abacus learning machine of the present invention, it is characterised in that described bead has a cavity and endoporus, bead it is interior
Hole is square, oval or polygonal；The endoporus of bead is provided with magnetic bodies.
Further, bead endoporus is using ellipse as preferred feature；Designing the advantages of oval is that bead moves flexible nothing
Dead angle, bead is circumferentially fixed to be rotated, and magnetic bodies is fixed on a certain specific place, the convenient and correct centering of Hall, reduce
Magnetic dosage, reduce cost of manufacture.
Further, the cavity of bead is connected firmly by the molding plastic to match with glue.
Described magnetic bodies can be magnet steel or magnet；
Further, described magnetic bodies is installed on bead endoporus perisporium；
Described magnetic bodies can make square, circular and polygon, but must be with bead close fit, in a kind of form, magnetic
Property object make and have a step, the purpose for making step prevents magnetic bodies from coming off.
The depth of described cavity is at least from bead radial surface 1.5mm.
A kind of bead of abacus learning machine of the present invention, applied to the abacus of connection calculator, magnetic bodies is installed in bead,
Position sensing can be formed with the Hall of pearl bar, the data real-time delivery of abacus can be made to single-chip microcomputer, by single-chip microcomputer by data
Show on a display screen, during Students ' Learning, can see that contrast answer carries out reviewing one's lessons correction on the display screen of calculator.
Brief description of the drawings
Fig. 1 is bead top view;
Fig. 2 is bead front view.
The invention discloses a kind of bead of abacus learning machine, as shown in Figure 1, 2, a kind of bead of abacus learning machine, its
Described bead 1 is characterised by using ABS resin as raw material, molding injection shaping, bead 1 has a cavity 2 and endoporus 3, bead 1 it is interior
Hole 3 is square, oval or polygonal；The perisporium of endoporus 3 of bead 1 is provided with magnetic bodies 4.
Further, the endoporus 3 of bead 1 is using ellipse as preferred feature；Designing the advantages of oval is that bead 1 moves flexibly
Without dead angle, bead 1 is circumferentially fixed to be rotated, and magnetic bodies 4 is fixed on a certain specific place, convenience and the correct centering of Hall,
Magnetic dosage is reduced, reduces cost of manufacture.
Further, the cavity 2 of bead 1 is connected firmly by the molding plastic to match with glue.
Described magnetic bodies 4 can be magnet steel or magnet, be installed on the perisporium of 1 endoporus of bead 3；Magnetic bodies 4 can be made
Make square, circular and polygon, but must be with the close fit of bead 1, in a kind of form, magnetic bodies 4, which makes, step, makes
The purpose of step prevents magnetic bodies 4 from coming off.
The depth of described cavity 2 is at least from the radial surface 1.5mm of bead 1.
A kind of bead 1 of abacus learning machine of the present invention, applied to the abacus of connection calculator, Magnetic Materials are installed in bead 1
Body 4, position sensing can be formed with the Hall of pearl bar, the data real-time delivery of abacus can be made to single-chip microcomputer, will by single-chip microcomputer
Data show on a display screen, during Students ' Learning, can see that contrast answer carries out reviewing one's lessons correction on the display screen of calculator.
It is to be understood by the skilled artisans that the bead 1 of the present invention, when abacus is installed, bead 1 should be with the mutual court of hall position
Other side direction assembles, and when bead 1 moves after assembling, there is bead 1 and the correct centering of Hall all the time, forms position and passes
Sense.
