摘 要:船舶航行使用自动化控制网络,网络信息的传输影响船舶航行状态,因此研究改进遗传算法的船舶网络优化调度方法。构建基于高层控制器局域网络协议(TTCAN)的船舶网络结构,分析高层控制器局域网络协议,在船舶网络的拓扑结构基础上,确定船舶控制网络矩阵周期中报文传输抖动最小为优化调度目标,利用模拟退火算法改进遗传算法,抑制遗传算法过早收敛情况,获取船舶网络矩阵周期报文传输抖动最小值,提高船舶网络通信质量。在模拟试验平台中对实际船舶控制网络开展试验,证明该方法报文传输时路径最短,能够有效节约传输时间,即使在恶劣天气条件下仍然能保证报文传输效率,确保船舶平稳航行。Ship navigation uses automatic control network, the transmission of network information affects ship navigation state, so the optimization scheduling method of ship network based on improved genetic algorithm is studied. Building high-level controller based on local area network structure, network protocol(TTCAN) ship analysis of high-level controller local area network protocol, on the basis of shipping network topology structure, control network matrix ship cycle minimum packet transmission jitter in order to optimize the scheduling objectives, using the improved genetic algorithm, simulated annealing algorithm, inhibition of genetic algorithm premature convergence. The minimum transmission jitter of periodic message of ship network matrix is obtained to improve the communication quality of ship network. Experiments on the actual ship control network in the simulation test platform show that the proposed method has the shortest transmission path, can effectively save transmission time, and can still ensure the efficiency of message transmission and ensure the smooth sailing of the ship even in bad weather conditions.
