基于XML的测控系统统一数据模型

摘要

为提高测控系统的通用性,设计了基于XML的代表测控系统共性的原生数据类以及代表测控系统个性的自定义数据类,采用生产者/消费者模式设计了统一组件数据接口,利用测控系统中常用的、共性的数据结构的原生算于,提供了测控系统自定义算子的开发方法及示例,统一了测控数据的描述形式、组件之间的数据交互行为和数据操作行为.实验结果证明:统一数据模型的设计能大大降低系统软件组件间的耦合,同时大大提高系统的可扩展性和易维护性.%To improve the universality of the measurement and control system, the native data type that on behalf of measurement and control system's commonness and the custom data category that on behalf of the characteristic were designed based on XML. A unified interface was designed based on producer/consumer model, the methods and examples to design custom data using native data were provided, which unified the form of a description of measurement and control data, the data exchange behavior between components and the data manipulation behavior. The Experimental results show that the design of the unified data model greatly reduces the coupling between software components, while greatly improving the system scalability and easy maintenance.
