Description
Technical field
The invention belongs to teaching aid technical field, more particularly to a kind of mathematics stochastic finite element demonstration teaching aid.
Background technology
For student, study is the major way of study on class, and teacher is lectured knowledge by Classroom Teaching
To student.This subject of Probability Theory and Math Statistics with Students ' Learning each stage, especially to university stage, probability theory with
Content involved by mathematical statistics is more rich, and knowledge point is more.The explanation form of teacher is changed into electronic courseware and teaches teaching, but
Still do without departing from uninteresting explanation knowledge point and largely the process of these old stuff of exercise.In teaching process, especially one
The probability distribution of a little variables cannot intuitively be expressed clearly with language, and this is accomplished by a kind of apparatus for demonstrating.
The content of the invention
To overcome above-mentioned technical problem, the invention provides a kind of simple structure, convenient stochastic finite element is counted
Demonstration teaching aid.
To achieve the above object, the present invention is realized using following technical scheme：
A kind of stochastic finite element demonstration teaching aid, including housing, bead, it is characterised in that：The housing is respectively equipped with up and down
Raised one and raised two, described raised one is provided with longitudinally through raised one funnel-form demonstration groove, the bottom of the demonstration groove
Portion is provided with demonstration hole, and described raised two are provided with several separate Sheng ball grooves, and the bottom of the Sheng ball groove is provided with vibration and passes
Sensor, the vibrating sensor is connected to circuit board, on described raised less than one and described raised more than two housing
It is provided with several and separates post, several described separation post spaced sets and perpendicular to the housing.
Several described separation posts constitute equilateral triangle.
The separation post is T-shaped structure.
The diameter in the demonstration hole is equal to the diameter of the bead.
The circuit board is connected to battery, be additionally provided with the circuit board converter, data storage, display,
Indicator lamp and power switch.
The demonstration groove, some separation posts, the Sheng ball groove are symmetrical with the plane of symmetry.
The present invention has the positive effect that：
The present invention is made probability generator using the separation post and bead on housing, and record is installed in ball groove containing
The device that data occur, when principle of probability demonstration starts, one group of bead falls from demonstration hole, and T-shaped separation post ensure that bead
Finally fallen into without departing from post is separated in Sheng ball groove, contain the mould vibrated when the vibrating sensor in ball groove can produce bead to fall
Intend signal, the data after analog signal is converted are stored, and show that each contains the bead quantity in ball groove by display screen, directly
See, facilitate, conventional efficient improves without the quantity for looking into several beads for wasting time and energy in Faculty and Students.

Specific embodiment
Referring to accompanying drawing 1,2, a kind of stochastic finite element demonstration teaching aid, including housing 1, bead 13,
The housing is respectively equipped with raised 1 and raised 2 11, described raised 1 and is provided with longitudinally through the projection about 1
One 10 funnel-form demonstration groove 2, the bottom of the demonstration groove 2 is provided with demonstration hole 3, and the diameter in the demonstration hole 3 is equal to described small
The diameter of ball 13, described raised 2 11 are provided with several separate Sheng ball grooves 5, and the bottom for containing ball groove 5 is provided with vibration
Sensor 9, the vibrating sensor 9 is connected to circuit board, described raised less than one 10 and described raised more than 2 11 institute
State and several T fonts are provided with housing 1 separate post 4, several described separation post 4 spaced sets constitute equilateral triangles and
Perpendicular to the housing 1, the circuit board is connected to battery 12, and converter 6, data storage is additionally provided with the circuit board
Device 7, display 8, indicator lamp and power switch, the demonstration groove 2, some separation posts 4, the Sheng ball groove 5 are with the plane of symmetry
It is symmetrical.
Operation principle of the invention is as follows：
Product installation and debugging of the present invention are good, turn on the power switch, a number of bead is put into demonstration groove, bead is from demonstration
Hole falls, and by separating the barrier effect of post, bead is turned left or turn right motion, and by stopping several times, bead drops to Sheng
In ball groove, vibration during due to dropping is arranged on the vibrating sensor contained in ball groove and produces analog signal, the analog signal to pass through
Converter is converted to data, and is stored by data storage, and most each bead quantity contained in ball groove is displayed in display at last
On device, recorded, analyze after close power supply, detaching products of the present invention are installed.
