【摘要】:多功能車(chē)輛總線(xiàn)(MVB)主設(shè)備通過(guò)預(yù)置的周期掃描表實(shí)現(xiàn)對(duì)周期信息的實(shí)時(shí)調(diào)度。針對(duì)使用傳統(tǒng)方法構(gòu)建周期掃描表所造成的負(fù)載信息均勻度較差這一缺陷,在對(duì)構(gòu)建周期掃描表這一組合優(yōu)化問(wèn)題進(jìn)行數(shù)學(xué)建模的基礎(chǔ)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(guò)采用"免疫算子"能夠有效避免抗體適應(yīng)度的退化,達(dá)到高效求得周期掃描表最優(yōu)解、周期信息負(fù)載均勻度大幅提高的目標(biāo)。并在OPNET Modeler網(wǎng)絡(luò)仿真平臺(tái)中搭建了由MVB主、從設(shè)備構(gòu)成的MVB網(wǎng)段,通過(guò)仿真驗(yàn)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.
