Advanced mathematics probability demonstration device

Abstract

The invention provides an advanced mathematics probability demonstration device which comprises a box body, a box opening is formed in an upper side of the box body, and a plurality of conical cylinders are uniformly and fixedly arranged in the box body; a support for supporting the box body is arranged on a lower side of the box body; an air distribution box is arranged in the middle of the support; a plurality of air nozzles are connected to an upper side of the air distribution box; upper ends of the air nozzles penetrate through a bottom wall of the box body and vertically face the interiors of the conical cylinders; the air distribution box is connected with an air inlet pipe; a pulse valve is installed at the middle of the air inlet pipe, a tail end of the air inlet pipe is providedwith an air pipe connector, and the pulse valve is electrically connected with a pulse valve controller; an inverted-L-shaped frame is arranged on an upper side of the box body, a camera is arranged on a lower side of a tail end of the inverted-L-shaped frame, control buttons are arranged on an outer side of the camera, a displayer is installed on the vertical section of the inverted-L-shaped frame, and a projector is arranged on an upper side of a horizontal section of the inverted-L-shaped frame. According to the invention, the demonstration statistics of a large number of thrown coins or thrown dices can be carried out conveniently, the demonstration process is recorded, the probability statistics efficiency is high, the intuitive demonstration of higher mathematics probability and widedevelopment of operation are realized, and a basis is provided for intelligent probability demonstration statistics.

Description

technical field [0001] The invention belongs to the technical field of advanced mathematics experiment equipment, and in particular relates to an advanced mathematics probability demonstration device. Background technique [0002] Advanced mathematics refers to the more complicated part of mathematics objects and methods compared with elementary mathematics. Broadly speaking, mathematics other than elementary mathematics is advanced mathematics, and there are also those who refer to the more in-depth algebra, geometry, and simple set theory and logic in middle school as secondary mathematics, and regard them as elementary mathematics in primary and secondary schools and university mathematics. Phase transition to higher mathematics. It is generally believed that advanced mathematics is a basic subject formed by calculus, more in-depth algebra, geometry and the intersecting content between them. [0003] Probability is a concept defined by people according to the law of ran...

Problems solved by technology

[0004] The existing advanced mathematical probability demonstration device generally throws coins or dice one by one during the demonstration process, and then records and counts the results; probability statistics require a large amount of data verification, and this demonstration device demonstrates one by one, which is extremely inefficient; It is beneficial for everyone to carry out the experimental verification of probability statistics, and often only a few people can only rely on the listening after the demonstration experiment, and passively accept the theory, which is not intuitive enough; the invention patent of the authorized announcement number is CN108492683B, an advanced mathematical probability demonstration device, which realizes a large number of Simultaneous demonstration of coins and dice, but this device only uses vibration to flip the coins and dice without throwing, plus a large number of coins or dice gather together during the flipping process and interfere with each other during the flipping process, the statistical results are convincing The power is not strong, which will interfere with the accuracy of the probability statistics results to a certain extent; on the other hand, it is easy to overlap and tilt during the flipping process, resulting in the inability to make statistics on the probability demonstration results

Existing demonstration devices are generally small in size and the demonstration process is not suitable for many people to watch, which limits the popularization and use of demonstration devices
