Research On Interaction Method Of The Collaborative Simulation System Based On Rti

With the constantly expanding of system simulation technology in the application field, more complex problems need to be resolved,with the computer simulation.As the traditional single collaborative simulation technology can’t meet the needs, the researchers in all countries around the world begin to research the HLA collaborative simulation technology for complex product.High-speed train is a typical complex product, its co-simulation technology research will be an important study for China’s high-speed railway. In this thesis, HLA/RTI collaborative simulation technology is used to the co-simulation research of China’s high-speed railway. It can help us to achieve the purpose of owning our independent intellectual property rights technology of train communication network control system.On the background of the National Science and Technology Support Project, Network System Virtual Simulation of High-speed Train Traction Drive and Train Network System, this thesis conducts in-depth study on the communication network system of CRH2and the collaborative simulation technology based on HLA/RTI. After analyzing the network architecture and communication theory of the CRH2train communication network, we analysis the system functional requirements and overall design of CRH2train communication network system based on HLA/RTI co-simulation. And then, a combination of the ARCNET network communication technology and HLA simulation technology is used to perform the co-simulation of the CRH2train communication network system based on HLA/RTI. In this thesis, the simulation of each communication function module of the communication network has been carried on the detailed design and analysis, and time advances of each RTI federal member is managed with the ARCNET token. After going through this, the train control information, status information and control commands can be correctly send and received, and the communication between the network communications equipment is real-time and reliable.The thesis is divided into six parts.The first part is an introduction, focuses on discussing the research background, research status at home and abroad and the research content and structure of this project. The second part analyses the CRH2train communication network, the system functional requirements and overall design of CRH2train communication network system based on HLA/RTI. The Third, fourth and fifth parts discuss the detail design and implementation of co-simulation system, by adopting the idea of modularity for each module function. Finally, the co-simulation system has been tested, and the feasibility of using RTI interaction method of collaborative simulation system as the co-simulation method of complex products such as high-speed rail is verified.
