Optimization of Program Upgrading of Traction Auxiliary Converters for Hybrid Rail Cars
In the late debugging and maintenance process of hybrid rail car,a method of upgrading DSP and FPGA program is proposed to solve the problems of removing baffles,connecting communication ports and using separate software to upgrade multiple programs.According to the feature that DSP and FPGA need to be stored in FLASH,the underlying program and the upper computer program are designed respectively,and the program design flow chart is given.After testing on the product,the method is proved to be effective.This method realizes the remote upgrade of DSP and FPGA program,avoids the modification of hardware,guarantees the reliability of original products,shortens the maintenance time,and saves a lot of time and human resources cost.
