Description
Technical field
This utility model is related to data statisticss device, and in particular to a kind of probability statistics presentation device of theory.
Background technology
Due to the definition of probability statistics it is very abstract, only by explanation it is difficult to allow classmates to understand that it contains during teaching
Justice, or understand and do not cause deeply that what is defined obscures, the understanding for making classmates deep using simple experiment in teaching process is general
Definition, the theorem of rate statistics, make that the rudimentary knowledge of classmates grasps more in a down-to-earth manner, be road that each teaching person both knows about
Reason, but how can allow experiment instrument and be not take up space and can function well as basic role, and structure is detachably, becomes
The difficult problem of teacher.
Utility model content
In order to solve the above problems, there is provided a kind of principle using probability statistics is more preferable come tested, help student
Ground understand theorem, definition, apparatus for demonstrating easy to use, this utility model devises a kind of probability statistics principle demonstration dress
Put.
Particular technique content of the present utility model is：A kind of probability statistics presentation device of theory, including dartlike weapon, install case,
Base, statistics disk, controller and display screen, statistics disk is magnetic circular disk body, along some concentric circulars corresponding with statistics disk
The ring-type or circular portion of area equation are divided equally in statistics disk segmentation, outwards dissipate segmentation by the ring-type along statistics disk radius or
Circular homalographic is split to form some statistics, side surface is counted described in aliquot and is provided with each statistics aliquot flexible adhesion piece of connection；System
Meter disk is assemblied in installation case open end by flexible adhesion piece correspondence；Installation box cavity is provided with the shake-up of correspondence statistics aliquot and opens
Close, the touch switch connects controller by data wire, and display screen is embedded with controller；Dartlike weapon end is provided with correspondence statistics disk
Magnetic chuck.
The flexible adhesion piece is cloth or rubber film；Case is installed to be connected on base by support bar, base lower end
It is provided with universal wheel.
Controller includes
For receiving the data reception module of touch switch induction information；
For counting the memory module that aliquot is numbered and coordinate is remembered to each；
Information and memory module coordinate information for being received according to data reception module is analyzed and draws statistics
As a result data analysis module.
For the display module for connecting display screen and shown data analysis module analysis result.
Advantageous Effects：Statistics disk is divided into into the impartial statistics aliquot of some areas, dartlike weapon is thrown by student and is produced
Probability data, by touch switch and controller statistical result will be drawn, and be shown using display screen, and probability statistics are taught
Learn, simple structure is easy to use, is easy to student memory to learn.
Description of the drawings
Accompanying drawing 1 is this apparatus structure sketch；
Accompanying drawing 2 is installation case diagrammatic cross-sectional view；
Accompanying drawing 3 is dartlike weapon structure diagram.
In figure 1 for statistics disk, 2 be support bar, 3 be base, 4 be universal wheel, 5 be controller, 6 be display screen, 7 for flexibility
Bonding sheet, 8 for install case, 9 be touch switch, 10 for dartlike weapon, 11 be magnetic chuck, 101 for statistics aliquot.
Specific embodiment
A kind of probability statistics presentation device of theory, referring to Fig. 1-3：Including dartlike weapon 10, install case 8, base 3, statistics disk 1,
Controller 5 and display screen 6, statistics disk 1 is magnetic circular disk body, and disk 1 will be counted along some concentric circulars corresponding with statistics disk 1
The ring-type or circular portion of area equation is divided equally in segmentation, and segmentation is outwards dissipated by the ring-type or circle etc. along the statistics radius of disk 1
Area is split to form some statistics aliquots 101, and the statistics end face of disk 1 is provided with each statistics flexible adhesion piece 7 of aliquot 101 of connection；
Statistics disk 1 is assemblied in the installation open end of case 8 by the correspondence of flexible adhesion piece 7；The inner chamber of case 8 is installed and is provided with correspondence statistics aliquot
101 touch switch 9, the touch switch 9 connects controller 5 by data wire, and display screen 6 is embedded with controller 5；Dartlike weapon 10
End is provided with the magnetic chuck 11 of correspondence statistics disk 1.
The flexible adhesion piece 7 is cloth or rubber film；Case 8 is installed to connect on the base 3 by support bar 2, base 3
Lower end is provided with universal wheel 4.
Controller 5 includes
For receiving the data reception module of the induction information of touch switch 9；
For counting the memory module that aliquot 101 is numbered and coordinate is remembered to each；
Information and memory module coordinate information for being received according to data reception module is analyzed and draws statistics
As a result data analysis module.
For the display module for connecting display screen 6 and shown data analysis module analysis result.
By statistics disk, 1 point is the impartial statistics aliquot 101 of some areas, throws dartlike weapon 10 by student and produces probability number
According to, statistical result will be drawn by touch switch 9 and controller 5, and shown using display screen 6, and probability statistics are imparted knowledge to students,
Simple structure, it is easy to use, it is easy to student memory to learn；The connection statistics aliquot 101 of flexible adhesion piece 7 is set, it is convenient to connect, and
And it is can to carry out displacement and contradict touch switch 9 that can throw in statistics aliquot 101 in dartlike weapon 10, produces statistical signal.
