摘　　要：船舶物联网是船舶自动化控制系统的重要组成部分,Mesh无线网络在物联网中承担着数据传输的任务。本文对船舶通信信道负载率调控方案进行研究,数据在Mesh无线网络传输时,有静态信道分配、动态信道分配和混合信道分配3种方案,混合信道分配更加适用于船舶物联网数据传输,提出了船舶物联网通信信道负载率估计方法,设计了DACA-LB信道负载率调控算法,分析了算法实现流程,并从数据传输时延和吞吐量比较了DACA-LB算法和ORPTD算法的优劣,结果发现DACA-LB算法更优。Ship's Internet of Things is an important part of ship's automatic control system.Mesh wireless network undertakes the task of data transmission in the Internet of Things.In this paper,the load rate regulation scheme of ship communication channel is studied.In the data transmission of Mesh wireless network,there are three schemes:static channel allocation,dynamic channel allocation and mixed channel allocation.The mixed channel allocation is more suitable for ship Internet of Things data transmission.DACA-LB channel load rate regulation algorithm is designed,the implementation process of the algorithm is analyzed,and the advantages and disadvantages of DACA-LB algorithm and ORPTD algorithm are compared in terms of data transmission delay and throughput.The results show that DACA-LB algorithm is better.
