快控电源支路控制器程序的远程升级研究

在 EAST 等离子体垂直位移快速控制电源(快控电源)的数字信号处理(DSP)执行控制程序远程升级中，通过改变“二次引导”的顺序结构，提出一种新的“二次引导”结构。该结构不需要汇编语言的参与，使用 C语言编写“二次引导”程序，同时将该结构与无线网络传输技术相结合，实现了对程序的远程升级固化。实验结果表明，所提出的结合无线网络的“二次引导”结构能够实现对控制电源 DSP 程序的远程加密升级。

Research on the remote upgrade of the programof the fast control power branch controller

In the remote upgrade of digital signal processing (DSP) control program of fast control powersupply for plasma vertical displacement on EAST, a new "second-level boot" structure is proposed by changingthe sequential structure of the "second-level boot". This structure does not require the involvement of assemblylanguage and uses C language to write the "second-level boot" program. The structure is also combined withwireless network transmission technology to enable remote upgrading and curing of the program. Theexperimental results show that the proposed "second-level boot" structure combined with the wireless network iscapable of cryptographically upgrading the control power DSP program remotely.
