摘　　要：表格驱动码是世界气象组织推荐并在全球范围内被广泛使用的数据编码格式,也是我国气象数据格式标准化实施中采用的主要国际互信通用格式之一。建立表格驱动码业务试验系统,依据观测系统和CIMISS数据环境核心业务构架,选择有代表性的观测数据和产品,针对其自描述和灵活扩展性特点,采用编码模板制定、码表动态加载、编码要素和序列向存储要素和模型映射转换、数据库存储模型设计等关键技术,建立其编码、传输、处理、存储和应用完整业务流程,试验和验证其业务适应性,为我国基于表格驱动码的气象数据格式标准化工作全面开展提供参考。The table-driven code forms are the data format recommended by the World Meteorological Organization and widely used around the world.It is also one of the major international common formats used in the standardization of meteorological data format within the China Meteorological Administration.Based on the main architecture of the observation system and CIMISS data environment,the representative observation data and products are selected,and the pilot operating system of Table Driven Code Forms is established.According to the self-description and flexible expansibility characteristics of table driven code forms,the coding templates are developed,and the code tables are dynamically loaded by the encoding/decoding software.The mapping and conversion of coding elements and sequences to the storage elements and models are realized,and the database storage model is designed.The complete data flow of encoding,transmission,processing,storage,and application is tested and verified,and can be the reference for the implementation of data format standardization based on table-driven code forms.
