Mathematics simulator used for buffon throwing-pin experiment and its control system

Abstract

The invention relates to field of mathematics training aid. To be specific, it is a mathematics simulator used for buffon throwing-pin experiment and its control system. Its simulator includes the body, coin inserting device and pin throwing device, wherein the body includes base, landing legs, front lateral plate, medium support plate, back lateral plate, No. 1 annulated column and No.2 annulated column. The coin inserting device and pin throwing device both include sliding device and shooting device. The shooting devices of mentioned coin inserting device and pin throwing device include shooting plate, rotating plate axis, supporting plate, shooting spring, flexible air bag, gas tank, ventilation hose and air pump. The pushing devices of mentioned coin inserting device and pin throwing device include pushing plate and pushing air cylinder. Its control system includes programmable logic controller, sensor unit, air pressure unit and servo controller. The simulator could make students directly sense the process of coin inserting (pin throwing) experiment to increase the interests and understanding of students on probability.

Description

technical field [0001] The invention relates to the field of mathematics teaching aids, in particular to a mathematical simulator for Buffon's needle throwing experiment and a control system thereof. Background technique [0002] Probability, also known as probability, chance rate, chance (probability) or possibility, is a basic concept of probability theory. Probability is a measure of the possibility of a random event occurring, and generally a real number between 0 and 1 represents the possibility of an event occurring. The closer to 1, the event is more likely to occur; the closer to 0, the event is less likely to occur, which is an objective argument rather than a subjective verification. [0003] Probability experiments generally include ball touch games, coin tosses, turntables, needle throwing tests, push pins and bottle cap throws, etc. [0004] Among them, the Buffon needle test mainly refers to: [0005] 1) Take a piece of white paper and draw many parallel lin...

Problems solved by technology

[0013] Existing artificial coin tossing (pin throwing) experiment is often carried out by a person's hand tossing coin (hand tossing needle), and the mode of counting next to another person carries out the experiment, yet, because the number of times that needs experiment is many, thus above-mentioned coin tossing (hand tossing needle) is experimented with. The method of needle) probability experiment needs a lot of manpower and material resources, and affects the efficiency of the experiment; so the current mathematical probability coin toss (hand throwing needle) experiment is often simulated by computer, and the computer simulation experiment makes it impossible for students to participate in the probability experiment, or cannot Feel the actual experimental process, so students can not deepen their understanding of probability; in view of this, there is an urgent need for a mathematical probability teaching that can make students intuitively feel the fun of coin toss (needle) probability experiment, and does not affect the efficiency of the experiment analog device
