Problems solved by technology

In the high-power test, the inverter control software cannot be debugged and run with an emulator, because if this will cause unpredictable circuit failures, which will cause fatal damage to the inverter, so in the high-power test, currently It is to debug the control software through other external interfaces (such as DA output), but if you want to observe different variables in this method, you need to repeatedly load or program the program, which is extremely inconvenient for debugging

Embodiment 1

[0018] A method for debugging the inverter control software during high-power tests: When designing the inverter control software, the control software header file containing the key parameters of the inverter is used as the configuration file, the relative positions between the variables are fixed, and the variable addresses are used as The only key field is used for identification; when performing a high-power test, the host computer imports the control software header file, so that the host computer obtains the right to control the key variables and state quantities of the inverter control software. The key parameters of the frequency converter include bus voltage sampling actual value, A phase current actual value, B phase current actual value, C phase current actual value, bus voltage sampling filter value, A phase current filter value, B phase current filter value, C phase Current filter value, d-axis current loop proportional coefficient, d-axis current loop integral coe...

Embodiment 2

[0020] Different from above-mentioned embodiment 1, say further, if figure 1 As shown, the debugging interface of the upper computer is programmed by using the object-oriented programming language. This debugging interface has at least a configuration module, a setting module, a monitoring module, a modification module, a fault recording module, and a program download module. During the high-power test, the process of debugging the control software of the frequency converter refers to figure 2 shown. The upper computer imports the control software header file through the configuration module, so that the upper computer obtains the right to control the key variables and state quantities of the inverter control software. The upper computer first sets the key variables and state quantities required for the test online through the setting module, sets the key variables and state quantities when a fault occurs, monitors the variable changes in real time through the monitoring mod...

Embodiment 3

[0022] The difference from the above-mentioned embodiment 2 is that further, when performing high-power tests, the process of debugging the new version of the inverter control software refers to image 3 shown. After modifying the source code of the inverter control software, the output file will be replaced by the previous version of the inverter control software through the program download module. The upper computer only needs to re-import the control software header file to be compatible with the modified control software, so as to be compatible with different inverter control software versions. The upper computer first sets the key variables and state quantities required for the test online through the setting module, monitors the variable changes in real time through the monitoring module, and changes the key variables and state quantities in real time by modifying the module when the inverter status needs to be changed. Good fault recording module, when a fault occurs,...

Abstract

The invention relates to a method for debugging the control software of a frequency converter during a high-power test, and belongs to the technical field of testing. If the existing inverter control software is run with an emulator during a high-power test, unpredictable circuit failures will be caused, causing fatal damage to the inverter, and debugging is also inconvenient. The present invention is a method for debugging the inverter control software when carrying out high-power tests: when designing the inverter control software, the control software header file containing the key parameters of the inverter is used as the configuration file, the relative positions between the variables are fixed, and the variables The address is used as the only key field for identification; when performing high-power tests, the host computer imports the control software header file, so that the host computer obtains the right to control the key variables and state quantities of the inverter control software. The method does not need an emulator, can monitor the internal variables of the control software online in real time and modify the internal variables of the control software, so that the control software can be debugged online without the emulator.

Description

technical field [0001] The invention relates to a method for debugging the control software of a frequency converter during a high-power test, and belongs to the technical field of testing. Background technique [0002] The inverter control software is one of the cores of the inverter, and the existing high-power inverter control software debugging methods mainly rely on emulators. When the project system is jointly debugged, when the system function and performance are debugged, only a small power test can be done with the emulator, and the internal variables of the period before the software stops can be observed. In the high-power test, the inverter control software cannot be debugged and run with an emulator, because if this will cause unpredictable circuit failures, which will cause fatal damage to the inverter, so in the high-power test, currently It is to debug the control software through other external interfaces (such as DA output), but if you want to observe diff...
