Abstract
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.关键词
