Abstract

The invention relates to the field of math teaching tools and specifically to a mathematical probability operation device for a coin-toss experiment and a control system of the mathematical probability operation device. The operation device comprises a machine body, a coin ejecting device, a coin receiving device and a coin returning device. The machine body comprises a stand, support plates, a bottom plate, a front baffle plate and a rear baffle plate, and a separator plate. The coin ejecting device comprises six coin ejectors. Each coin eject comprises a coin ejecting plate, a coin supporting plate, a first spring, a first ejecting column, a first iron block, and a first electromagnet. The coin receiving device comprises a rodless push plate cylinder, a sliding block, a coin receiving plate, a limiting plate, a rotating plate cylinder, a connecting base, a rotating wheel and a slide rail. The coin returning device comprises a left returning device and a right returning device. The control system comprises a programmable controller, a sensor unit, an air pressure unit and a servo controller. The operation device and the control system can satisfy the needs of frequent mathematical probability experiments and enable students to learn the process of coin-toss experiments directly.

Description

technical field [0001] The invention relates to the field of mathematics teaching aids, in particular to a mathematical probability calculation device and a control system for a coin tossing experiment. 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-touching games, coin tosses, turntables, needle-throwing experiments, thumbtack throwing and bottle cap throwing experiments. The above experiments should be done by students themselves. These experiments are relatively simple...

Problems solved by technology

[0007] Existing artificial coin tossing experiments are often carried out by one hand tossing a coin and another person counting next to it. However, due to the large number of experiments required, the method of the above-mentioned coin tossing probability experiment needs a lot of manpower and material resources, and affects Experimental efficiency; therefore, the current mathematical probability coin tossing experiments are often simulated by computers. Computer simulation experiments prevent students from participating in probability experiments, or cannot feel the actual experimental process, so that students cannot deepen their understanding of probability. In view of this , there is an urgent need for a mathematical probability coin tossing device that can enable students to intuitively feel the fun of the coin toss probability experiment without affecting the efficiency of the experiment
