Research on multi-load bus system driving ability

Intord bus system is a high frequency industry bus system which uses the twisted wire as transmission line.The length of transmission line in this system is about 10 meters and 120 loads are loaded at the driven port.In the developing process,the system needs to judge if 120 loads can be driven properly by the bus system through the way of simulation in advance.The simulation work includes two parts.First part,it needs to setup the circuit model of the 10 meters long twisted pair on the basis of the analysis of twisted pair parameter using the theory of transmission line.In this part it needs to choose the right model between distributed system and Lumped system.Second part,it sets up the Intord circuit simulation system using the simulink toolbox in Matlab.It can know clearly about the bus system driving ability in advance before the system are fully developed through the circuit model simulation.It also gets some valuable direction for the ongoing developing work.
