摘要
随着空间技术的快速发展,使用数管模拟器模拟数管分系统进行测试已成为趋势。为了使数管模拟器软件能够适应航天器数据管理新的变化,降低软件实现难度,根据用户需求和已有硬件平台,提出了一种软件设计。本设计采用数据处理分层体制协议来降低软件实现的复杂性,使用数据包进行数据处理,并利用数据帧来完成数据的传输。该模拟器进行了100 h的各项功能老练试验,结果表明,该设计可靠、稳定、能满足设计要求。
With the rapid development of space technology,using spacecraft OBDH simulator which simulates On Board Data Handling subsystem to test the design of spacecraft has become a trend.In order to make the software of OBDH simulator to adapt the new changes of the OBDH subsystem and reduce the difficulty of software,be suitable for demand of user and existing hardware platform,a software design has been proposed in this paper.The design uses a layered system of data processing protocols to reduce the software complexity,uses data packets to process data and completes the data transmission based on data frames.The simulator has completed a 100 hours sophisticated test.The result indicates that this design is reliable,stable,and it also can meet the design requirements.
