摘要
随着当前船舶自动化、高速化的发展趋势,船舶通信设备功能也日趋复杂,对无线网传感通信控制技术要求也逐渐增高。无线传感通信网络控制技术的运行效果直接影响船舶航行安全,由于船舶航行过程中数据种类复杂多样,传统船舶网络通信控制技术难以及时对船舶网络信息节点进行优化。因此,对当前常用的船舶无线传感网络通信控制技术进行分析,结合环型拓扑结构的以太网的交换机模型对通信节点优化控制方法进行创新,从而改善传统方法中存在的数据传输误差等问题。为了验证方法的使用效果,对数据传输的精准度和时延情况进行检测,检测结果表明,结合环型拓扑结构的交换式以太网的交换机模型对通信节点优化控制方法可有效减少信息传输延时和误差问题,具有较高的可行性。
The operation effect of wireless sensor communication network control technology directly affects the safety of ship navigation. However, with the development trend of ship automation and high speed, the functions of ship communication equipment are becoming more and more complex, and the requirements for wireless sensor communication control technology are also increasing. Due to the complexity and diversity of the data in the process of ship navigation, the traditional ship network communication control technology is difficult to optimize the ship network information node in time.Therefore, the communication control technology of ship wireless sensor network is analyzed, and the communication node optimization control method is innovated by combining the switch model of ring topology switched Ethernet, so as to improve the data transmission error and other problems existing in the traditional method. In order to verify the effectiveness of the method, the data transmission delay is detected under different network structure and traffic parameters, and the upper limit of network delay is given. the detection results show that the optimal control method of communication node based on the switch model of switched Ethernet with ring topology can effectively reduce the information transmission delay and error, and has high feasibility.
