Advanced mathematics probability demonstration device

Abstract

The invention provides an advanced mathematics probability demonstration device, and relates to the field of teaching equipment. The advanced mathematics probability demonstration device comprises a base, wherein the surface of the base is provided with an information acquisition mechanism, the upper surface of the base is provided with a probability experiment mechanism, the inner bottom wall of the base is provided with a driving mechanism, the surface of the base is provided with a control mechanism, the surface of the base is rotatably connected with a connecting shaft, and rope belts are fixedly connected to the surface of the connecting shaft and symmetrically distributed on the front surface and the back surface of the base. According to the invention, a magnet is powered on, an electromagnet and magnetic plate attract each other, then a driving rod is pulled to move downwards, a moving block moves downwards along with the driving rod, a reset spring is compressed, energy is stored, after the driving rod does not move any more, the electromagnet is powered off, the reset spring drives the moving block to reset to throw a dice upwards and throw the dice, and after the dice is stabilized, a camera is controlled to take a picture, and information is acquired through photos subsequently, so that errors are avoided.

Description

technical field [0001] The invention relates to the technical field of teaching equipment, in particular to an advanced mathematics probability demonstration device. Background technique [0002] In advanced mathematics teaching, probability is a concept defined by people according to the rules of random events. In classical probabilistic teaching, teachers often use some actual probability demonstration experiments to make students learn the knowledge of probability more intuitively. The most common one is the coin tossing experiment, that is, after multiple coin tosses, the probability of getting the head and tail of the coin is 1 / 2; or throwing dice, and counting the probability of each point of the dice, that is, the probability is six One-half; or the number of balls with the same number of different colors, the probability of randomly drawing each color ball. [0003] When the applicant applied for the present invention, after searching, it was found that a Chinese pa...

Problems solved by technology

[0008] Aiming at the deficiencies of the prior art, the present invention provides an advanced mathematical probability demonstration device, which solves the problem of manual collection of dice points, which is prone to recording errors, poor teaching effect, and needs to be close to the device to clearly observe the dice points , that is to say, only a small number of students can observe clearly, which affects the learning efficiency of students and the problem that it takes a long time to record continuous rolls of dice
