Abstract

The invention discloses a digitized cart track system capable of automatically recognizing direction and distance of motion and a measuring method thereof, and belongs to the technical field of physical teaching tools. The digitized cart track system comprises tracks and a moving cart arranged on the tracks, and the moving cart is internally provides with an MCU processor, a reflective photoelectric sensor, a power module and a wireless communication module; the reflective photoelectric sensor, the power module and the wireless communication module are all connected to the MCU processor; the tracks are provided with two guide grooves of which the spacing is equal to that of wheels of the moving cart, and two black and white grating strips of which the phase difference is 90 degrees are arranged between the tracks. According to the digitized cart track system capable of automatically recognizing the direction and distance of motion and the measuring method thereof, based on a photoelectric method, on the condition that a traditional experimental method is not changed, the direction and distance of motion of the cart are measured by adopting a non-contact way, and the system and the method are applicable to various experiments of the exploration of uniform linear motion laws, the exploration of the relation among acceleration, force and mass, cart collision and the like.

Description

technical field [0001] The invention relates to a digital trolley track system capable of self-identifying the direction and distance of movement and a measuring method thereof, and belongs to the technical field of physical teaching aids. Background technique [0002] It is very important to study the law of motion of the trolley in high school basic physics experiments.

AI Technical Summary

Problems solved by technology

[0003] The currently used experiments such as exploring the law of motion mainly have the following shortcomings: (1) It is troublesome to use a dot timer or an external displacement sensor to test information such as displacement. Assembly is troublesome, difficult to operate, and there is additional force on the movement of the car

(2) The measurement and calculation of experimental data is complicated, and it is necessary to measure and calculate the experimental results separately for the experiment

(3) For tests involving collision experiments and other troubles, it is impossible to judge the running direction of the car

(4) Experimental results cannot be uploaded to display terminals such as computers, and digital teaching cannot be carried out
