基于串口的星载激光器控制软件升级方法研究

Research on the upgrade method of spaceborne laser control software based on serial port

摘要:

针对传统DSP应用程序烧写的缺陷，设计了一种利用串口对应用程序进行升级的方法。首先阐述了在线升级方案的必要性、所依赖的硬件系统组成和在线升级方案的总体构架，然后分别对应用程序HEX数据文件的转换方法、HEX文件重新编码的上位机软件设计方法和DSP升级软件设计方法等进行了详细的描述，最后通过实验证明提出的在线升级方法有效，可靠，解决了星载激光器控制软件必须通过JTAG口进行烧写的缺点，为星载激光器产品长期在轨执行任务时的软件远程升级奠定了基础

Abstract:

In view of the shortcomings of traditional DSP application flashing, this paper designs a method to upgrade the application by using serial port. This paper first expounds the necessity of the online upgrade scheme, the composition of the hardware system and the overall architecture of the online upgrade scheme, and then describes the conversion method of the application HEX data file, the design method of the host computer software for HEX file recoding and the design method of the DSP upgrade software respectively, and finally proves that the online upgrade method proposed in this paper is effective and reliable through experiments, which solves the shortcomings that the spaceborne laser control software must be programmed through the JTAG port. It lays the foundation for the remote software upgrade of spaceborne laser products when they perform tasks in orbit for a long time
