摘　　要：为了满足当前数据交换中发布订阅需求,以及实时性和复杂性要求,设计了一种基于优先级任务的数据交换模型,并利用该模型开发TTS数据交换平台的核心模块。给出数据交换平台的整体框架以及数据集交换流程,并详细介绍任务泵、线程池等模块的实现。实际的应用测试表明,该平台能够实现复杂数据发布订阅应用,满足系统对实时性要求。In order to satisfy the demands of data subscribe/publish,real-time and complexity in present data exchanging,a data exchanging model based on task-priority model was designed.Using this model the core modules of TopTang Software（TTS）exchanging platform were developed.This paper proposed the framework of TTS platform,discussed all the processes of dataset exchanging,and then,illustrated the implementation of the core modules,including task-pumper and thread-pool.The practical application test demonstrates TTS can satisfy the requirements of publish/subscribe and real-time.
