TTP/C is a highly fault-tolerant bus protocol defined based on TTA architecture.According to its characteristics of distributed,multi-point serial,and time-triggered,based on system reliability theory and Stochastic Petri Net(SPN)theory,a reliability analysis model based on SPN is proposed.By setting the occurrence delay of related events,the model is solved by PIPE 4.3.0 analysis software,and the theoretical reliability of TTP/C is obtained.The model and simulation method proposed in this paper accomplish the inheritance and breakthrough of the traditional reliability analysis method.The simulation results prove that the TTP/C bus protocol has a very low failure rate which can meet its requirements in the aerospace control application field.
