The simulator comprises a machine body, a coin feeding device and a needle feeding device, wherein the machine body comprises a base plate, supporting legs, a front side plate, an intermediate supporting plate, a rear side plate, a first annulated column and a second annulated column; the coin feeding device and the needle feeding device respectively comprise an object sliding device, an object bounding device, an object pushing device and an object conveying device; each object bounding device comprises an object bounding plate, a rotating plate shaft, an object supporting plate, an object bounding spring, a telescopic airbag, a gas storage tank, a ventilation hose and an air pump; each object conveying device comprises a material falling hopper, a conveying bin, a conveying roller and a conveying belt. The control system of the mathematical probability teaching simulator comprises a programmable logic controller, a sensor unit, an air pressure unit, a servo motor unit and a servo controller. According to the mathematical probability teaching simulator and the control system thereof disclosed by the invention, the requirements of mathematical probability experiments with more experiment times can be met, and students are enabled to visually experience the processes of coin and needle feeding experiments.

Description

technical field [0001] The invention relates to the field of mathematics teaching aids, in particular to a mathematics probability teaching simulator and its control system. 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 lines with a distance of a on...

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
