摘　　要：[目的]在船用欠稳定网络环境下,为提高数据传输效率和减少通信费用,提出一种基于“请求-响应”模式的分布式信息集成模式。[方法]结合信息元的有效组织和管理,通过详细定义信息元的组织方法,实现元数据的高效获取和平台元数据库的创建。此外,研究还涉及信息标识解析、元数据映射配置及SQL语句的动态解析编译器设计,有效处理语义异构问题,并实现不同软件系统间数据的集成。[结果]实验结果显示,与传统模式相比,基于“请求-响应”模式的数据集成方法显著降低了24 h通信量。在单项数据集成实验中,24 h通信量从原有模式的3456000 byte显著降低至3696 byte(每小时请求)和154 byte(每天请求)。对于10项数据集成,24 h通信量从原有模式的11232000 byte降低至17952和748 byte。此外,还有效降低了数据传输频次,同时保持数据信息利用的有效性,显著提高数据处理的效率和准确性。[结论]证明了基于“请求-响应”模式的分布式信息集成方法在船用欠稳定网络环境下的高效性和实用性。[Objectives]In the face of unstable network environments at sea,this study aims to develop a novel information integration model and method to improve data transmission efficiency and reduce communication costs.[Methods]This study introduces a distributed information integration method based on the"request-response"model,which is combined with the effective organization and management of information elements.By precisely defining the structure of information elements,the efficient acquisition of metadata and the creation of platform metadata databases were achieved.Furthermore,the study involves the design of an information identifier resolution system,metadata mapping configuration,and a dynamic parsing compiler for SQL statements,effectively addressing the issue of semantic heterogeneity and achieving seamless data integration between different software systems.[Results]Experimental results indicate that,compared to traditional models,the"request-response"based data integration method significantly reduces the 24-hour communication volume.In individual data integration experiments,the 24-hour communication volume was reduced considerably from 3456000 bytes in the original model to 3696 bytes(per hour request)and 154 bytes(per day request).For 10-item data integration,the 24-hour communication volume was reduced from 11232000 bytes in the original model to 17952 bytes and 748 bytes.Additionally,this method effectively reduces the frequency of data transmission while maintaining data utilization efficiency,significantly improving data processing efficiency and accuracy.[Conclusions]This study demonstrates the efficiency and practicality of the distributed information integration method based on the"request-response"model in unstable maritime network environments.It provides a new technical approach for ship operation and maintenance data integration and offers valuable insights for research in related fields.
