【摘要】:多功能車輛總線(MVB)主設備通過預置的周期掃描表實現(xiàn)對周期信息的實時調度。針對使用傳統(tǒng)方法構建周期掃描表所造成的負載信息均勻度較差這一缺陷,在對構建周期掃描表這一組合優(yōu)化問題進行數(shù)學建模的基礎上,提出了一種基于免疫遺傳算法的優(yōu)化方案。該算法通過采用"免疫算子"能夠有效避免抗體適應度的退化,達到高效求得周期掃描表最優(yōu)解、周期信息負載均勻度大幅提高的目標。并在OPNET Modeler網絡仿真平臺中搭建了由MVB主、從設備構成的MVB網段,通過仿真驗證了優(yōu)化方案的有效性。
[Abstract]:Multifunctional Vehicle Bus (MVB) main equipment dispatches periodic information in real time by preset periodic scanning table. Aiming at the shortcoming of poor uniformity of load information caused by constructing periodic scanning table by traditional methods, a basis is proposed based on mathematical modeling of the combined optimization problem of constructing periodic scanning table. This algorithm can effectively avoid the degeneration of antibody fitness by using "immune operator" to obtain the optimal solution of periodic scan table and greatly improve the uniformity of periodic information load. The effectiveness of the optimization scheme is verified by simulation.
