      Table 1. Differences and similarities between shipboard and shore-based metadata dictionaries

      元数据类型船端元数据岸基元数据
      定义船端元数据字典记录船用设备及其软件系统中的元数据信息,反映设备状态、操作参数等具体细节中心平台利用岸基元数据字典统一管理和集成各船端数据的目录,包含所有船端数据的映射和标准化定义
      数据类型多为实时监测数据,如温度、转速、扭矩等多为整合后的分析数据,用于决策支持和运维管理
      采集方式通过船端系统的自动监测和记录功能获取通过各船端数据字典的上传和汇总生成
      更新频率由于船端设备的实时监测需求,数据字典更新较为频繁,通常按秒或分钟级别进行更新相对较低,通常按小时或日级别进行更新,以保证数据的稳定性和一致性
