Development and production of program-controlled chopper based on Raspberry pi

Abstract

Optical signal modulation plays an increasingly important role in many aspects such as photoelectric detection. Information technology plays an increasingly important role in promoting social progress. The integration of optics and electronic information technology is of great significance for social progress and scientific and technological development. Using computer science to improve and upgrade experimental equipment can make experiments more accurate and easier to operate. This subject is mainly based on the python programming of Raspberry PI. By controlling GPIO interface, the stepper motor is regulated and optimized. The photoelectric information technology and software program are combined and applied to scientific experiments.

By studying how to program and drive GPIO, and developing appropriate and reasonable algorithm and control method, so as to achieve the ability to regulate and control the stepping motor, the program controlled chopper based on Raspberry Pi was developed with chopper board installed on the stepper motor. Firstly, this paper introduces the definition, function and application of light modulation, and then introduces the related information and application of Raspberry Pi as the chopper control module. Secondly, the structure of the program-controlled chopper based on Raspberry Pi is described. Finally, the program of the program - controlled chopper is explained and analyzed. Through hardware regulation and software development, the program-controlled chopper based on Raspberry Pi was developed and manufactured by scientific algorithm.

Key Words: Chopper; Raspberry Pi; Light modulation; Linux
