摘　　要：文中针对船载网络数据集中过程中因设备通信方式不同,协议具有异构性,不确定性设备协议变动使数据接入系统复杂的问题,提出一种基于TCP/IP协议的可配置数据集中方法。首先增加采集适配层将设备通信接口统一成工业以太网,船载设备通过转以太网模块实现物理层接入,使数据经以太网传输到数据管理平台;其次将网络协议解析处理过程描述成解析配置表,引入用户配置机制,实现对新设备协议的按需变动;最后借鉴有限状态及思想设计不确定协议的解析和数据抽取算法。实验结果表明:该船载设备数据集中方法可对采集数据字段颗粒度抽取,避免因通信协议变动重新编写解析和处理程序,具有良好的灵活性和普适性。Considering that the data access system is complicated due to different communication modes of devices,heterogeneous protocols and uncertain device protocol changes in the process of data concentration in ship-borne network,a configurable data concentration method based on TCP/IP protocol is proposed.Firstly,the acquisition adaptation layer was added to unify the communication interface of the equipment into industrial Ethernet,and the shipborne equipment can access the physical layer through the Ethernet module,so that the data can be transmitted to the data management platform through Ethernet.Secondly,the network protocol parsing process was described as parsing the configuration table,and the user configuration mechanism was introduced to realize the on-demand change of the new device protocol.Finally,the analysis and data extraction algorithm of uncertain protocols were designed with reference to finite state and thought.The results show that the granularity of collected data fields can be extracted by this method,which avoids the need to rewrite the analysis and processing program because of the change of communication protocol,and has good flexibility and universality.
