Problems solved by technology

The traditional distributed simulation system can only continuously modify the IO computer acquisition codes of each system according to the needs of the simulation personnel. The more complex the system, the more IO data types, the workload will increase geometrically, and the complexity of the code will continue to rise. Generalization and scalability capabilities are greatly reduced
