基于工作流技术的测控信息会签系统设计

A Countersign System for Aerospace Tracking,Telemetry and Command Information Based on Workflow Technology

为了解决地面测控中心采用纸质方式会签测控信息工作量大、效率低、多航天器支持能力差的问题,论述了测控信息会签系统的设计方法、实施效果。通过分析载人航天测控信息会签的需求和特点,采用工作流技术对测控数据处理过程进行阶段划分和抽象建模,设计用户、岗位和任务的多对多映射方式,规划层次化的会签流程模板,实施会签流程多层次复用和动态组装,构建基于B/S(Browser/Server,浏览器/服务器)模式跨平台的系统架构,以数据库实时同步为基础,建立对称的实时热备工作模式,设计多任务通用的数据库结构,实现了测控信息的在线会签。实际应用表明,基于工作流技术的在线会签系统大幅缩短了测控数据处理周期,提高了航天器上行控制效率,有较高的推广价值。

This paper presents a design method and its implementation effect for an auxiliary support countersign system of TT＆C （tracking, telemetry and command） information to reduce the workload of space control centers and the increase its efficiency and enhance its multi-spacecraft support capability. Following analysis of the requirements and characteristics of manned spaceflight, workflow technology is used to categorize and abstract the processing flow of TT＆C data for modeling. A multi-to-multi relationship mapping is designed for users, posts and tasks. Hierarchical countersign process templates are made for implementation of reuse and dynamic assembling of countersign procedures. A B/S （Browser/Server） -based cross-platform system architecture is built. An activestandby real-time system is realized for online countersign with a multitask-support universal database. Applications of the system in real missions show that the workflow-based online countersign system significantly shortens TT＆C data processing cycles and increases the uplink control efficiency for spacecraft.
