Design of a reconfigurable extendible real-time multi-bus simulation system on the information flow in the control systems

A simulation system on information flow is designed to emulate the data communication on the RS-485 bus, the 1553B bus and the Ethernet bus. This simulation system has a high requirement for the extendibility, and it must have an ability to regulate and reconfigure the information flow on the three buses. To deal with the above problems, the simulation system has to be designed as a reconfigurable extendible real-time multi-bus simulation system. In order to meet the real-time requirements for the simulation of the information flow and the universal property for the most systems, this simulation system must be carried out based on a real-time operating systems (VxWorks) and a common hardware platforms. Firstly, this simulation system will have a total emulation and a whole simulation for the information flow, the communication status, the monitor nodes and the control nodes on each of the three buses. Secondly, this simulation system defines an extendible protocol between the simulation sever and the simulation terminals, and strictly plan the information flow among the simulation terminals to achieve the design requirements of the actual system. And then the simulation system has to own a reconfigure software components and a complete database functions of recording and stacking the data.
