基于计划任务运行的测控设备软件体系设计与实现

Design and Implementation of theSpace Ground Station System Software Based on Plan and Task

以往的地面测控系统软件主要面向单机设备功能设计,随着航天测控业务的发展,这种设计的局限性日益明显,因此提出一种新的面向应用流程的设计思想。文中,首先约定与面向应用流程体系设计相关的一组核心概念,接着从流程分解与设计、应用流程设计和软件体系设计等几个方面对面向应用流程的设计思想进行阐述。然后,结合工程项目的研制实践,给出基于计划任务运行的测控应用软件的一个设计简述。最后对面向应用流程设计的应用前景作了分析,并提出需要进一步解决的重点难点问题。

The traditional space ground station system software is Device-oriented.A software must operate lots of individual devices to complete a tracking task.With the development of space services and the increasing of the number of devices,the shortcoming and limitation of such software are more and more obvious.The workflow-oriented software design pattern for the space ground station system is introduced in this paper.The work-flow-oriented software design is intended to relieve the labor intensive process required to prepare,execute a specific task and to print the task report.First,several core concepts related with the work-flow-oriented software design pattern are defined in this paper.Then,the analysis and design of the work flow,the architecture of the software,and the key point of the design pattern are described.And an example based on plan and task which is designed with the pattern is provided according to the application of the project.At last,the prospect of the design pattern is analyzed,and difficult problems of the design pattern are listed.
