Abstract

Digital twin technology can support teachers in this major to complete monitoring related topics and application research and serve teaching and scientific research through the establishment of automatic monitoring teaching model laboratory and in-depth combination with the current students’ skill training needs in this major. This exploration aims to make the visual sensor industry have a steady stream of talents. Promoting the development of visual sensor technology is to promote the development of science and technology. Based on the teaching research of visual sensing design using digital technology, a set of teaching systems of visual sensing design is designed by using the methods of literature research and investigation and analysis. Special topics are set up from the aspects of professional subjects; regarding course content, various sensor principle research courses, visual sensor design courses, experimental courses, and example courses are set up; teaching methods are divided into online and offline synchronous classes; the evaluation method should focus on the distribution, examples, and practice. The results show that traditional classroom teaching is seriously separated from extracurricular learning. Most students are in a state of passive acceptance of knowledge and have few thinking activities. The established teaching system integrates brain and cognition, photoelectric foundation, sensory imaging, visual sensing imaging, visual sensing technology courses, computer technology, virtual experiment courses, and physical experiment courses. It can carry out more than 30 experiments of optical microscopic imaging and X-ray imaging based on the principle of visual sensing. Therefore, the teaching effect and teaching mode of the proposed digital visual sensing teaching system have been greatly improved.

Highlights

In the twenty-first century, people are used to digitization and seek the optimal solution of learning and life through big data
Physical model refers to all kinds of equipment in the real world: human, mechanical arm, numerically controlled machine tool, automatic instrument, and mobile phone. e virtual world can be understood as a digital world composed of various intelligent computing devices; through the Digital twins (DTs) technology, every device in the real world will have a digital entity in the virtual world, which has exactly the same appearance and internal structure e characteristics of the digital age include intelligence, integration, and parallelism [1]. e traditional teaching mode needs to invest a lot of physical equipment, venues, and personnel
Building a DTs production system integrating the manufacturing process can realize the digitization of the whole process from product design to production planning to manufacturing execution and raise the level of product innovation and manufacturing efficiency and effectiveness to a new level. e DTs body refers to a virtual model completely corresponding and consistent with the physical entities in the real world, which can simulate its behavior and performance in the real environment in real time, known as the DTs model

Summary

Introduction

In the twenty-first century, people are used to digitization and seek the optimal solution of learning and life through big data. It means that people have unknowingly entered the digital age, such as the music app that judges and recommends users’ favorite songs through big data, lists of popular film and television dramas, and online shopping of favorite items. Digital twins (DTs) complete the mapping of the physical model in virtual space in the real world. Physical model refers to all kinds of equipment in the real world: human, mechanical arm, numerically controlled machine tool, automatic instrument, and mobile phone. Applying DTs technology to online teaching can break the traditional teaching mode and realize digital teaching
