Immersive Virtual Simulation System for Principles of Communications Based on Unity 3D

Utilizing virtual reality technology for 3D modeling of experimental equipment, this study achieved digital simulation of the signal transmission process and developed a multi-user collaborative, immersive virtual simulation system for communication principles using the Unity 3D rendering engine. This system allows multiple students enter the same virtual space simultaneously via the network to collaboratively manipulate 3D virtual instruments and complete communication experiments such as modulation and demodulation of AM signal. The underlying information exchange architecture employs the MySQL database to store user data, uses C# for networking servers, and establishes a data exchange protocol with Socket, creating a decoupled foundation network that allows real-time data reading and exchange from multiple clients to meet the requirements of online collaboration. This approach addresses the issues of insufficient space and equipment resources in conventional laboratories, alongside overcoming the limitations on students' practice time and space, and streamlines the evaluation process in experimental education.
