Problems solved by technology

[0008] Among them, after the step (3), it is necessary to connect the DSP board with the actual hardware device inverter, and start the step (4), then whether the DSP program is correct, whether the DSP control system and the inverter hardware are normal and trouble-free The verification must be carried out at the same time. If there is a problem in any link, it must be debugged and checked repeatedly. It is not easy to quickly locate the problem, and it is easy to cause hardware damage or even personal injury during the debugging process (especially the development of high-power and high-voltage equipment. and debug)

Embodiment Construction

[0041] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0042] The DSP program of the present invention runs inside the DSP chip, and the DSP board with the DSP chip as the core is placed in the inverter, and the inverter is connected with the DC source and the AC source through the DC and AC strong current lines. In order to be safe and efficient, the inverter, DC source, and AC source are all virtualized as programs, and added to the vicinity of the original "DSP program", it can be judged whether each hardware module on the DSP board is normal, and the above mentioned The test process is consistent with the real test, and the test results can basically reflect the real results.

[0043] like figure 1 Shown, the embedded virtual test system based on DSP of the present invention has realized the full set of emulation function of DSP tested program, is core with DSP, embedded following unit with the form of progr...

Abstract

The invention relates to a DSP-based embedded virtual test system. A virtual inverter unit, a virtual DC source unit and a virtual AC source unit are embedded in a DSP in the form of program; and the virtual DC source unit provides DC voltage signals for the virtual inverter unit and a to-be-tested DSP program and control algorithm, the virtual AC source unit provides AC voltage signals for the virtual inverter unit and the to-be-tested DSP program and control algorithm, the virtual inverter unit provides AC and DC current signals for the to-be-tested DSP program and control algorithm, the virtual inverter unit provides DC current signals for the virtual DC source unit, and the to-be-tested DSP program and control algorithm provides modulation signals for the virtual inverter unit. The virtual test system of the invention improves the DSP development and test efficiency and the test safety, and reduces the development and test cost.

Description

technical field [0001] The invention relates to a virtual test system, specifically a DSP-based embedded virtual test system. Background technique [0002] The current development process of DSP (DigitalSignalProcessor, digital signal processor) is: [0003] (1) Research on theoretical algorithms; [0004] (2) Use Matlab for simulation. Matlab is a commercial mathematical software produced by MathWorks in the United States. It is an advanced technical computing language and interactive environment for algorithm development, data visualization, data analysis and numerical calculation. It mainly includes Matlab and Simulink. ; [0005] (3) DSP programming; [0006] (4) Burn the DSP program into the DSP chip on the DSP board, and then carry out a strong current test experiment to verify whether the DSP program, each hardware module on the DSP board and each hardware module of the inverter can operate normally. [0007] Among them, the step (4) specifically includes: testing...
