Problems solved by technology

[0002] In the grid-connected inverter control technology of the power system, most of its various modulation methods are carried out by software, so the simulation debugging of the software in the grid-connected state cannot perform single-step execution, interruption points, etc. A series of operations, because once misoperation, it is likely to cause problems such as bombing
Therefore, in order to avoid serious consequences caused by misoperation during simulation, general developers simply do not perform software simulation debugging, which affects the efficiency of code debugging

Abstract

The invention relates to an online simulation debugging protection method for a microprocessor, which is characterized by comprising the following steps: connecting the microprocessor with the input end of an independent monostable flip-flop, and connecting the output end of the monostable flip-flop with an IGBT Drive circuit, when the program running on the microprocessor runs at full speed, the microprocessor regularly gives a trigger signal to the output of the monostable flip-flop, and the timer in the microprocessor is set to apply to the PWM generator function, timing The second device is a timer that is not used by the PWM generator function. The method proposed by the present invention solves the problems existing in the prior art. Using the method provided by the present invention, the simulation debugging of the microprocessor can be performed, and various non-full-speed operation modes can be entered, such as breakpoint, single-step Execution and other operations greatly improve the development and debugging efficiency of developers.

Description

technical field [0001] The invention relates to an online simulation debugging protection method for a microprocessor. Background technique [0002] In the grid-connected inverter control technology of the power system, most of its various modulation methods are performed by software, so the simulation debugging of the software in the grid-connected state cannot perform single-step execution, interrupt points, etc. It is operated in series, because once misoperation, it is likely to cause problems such as bombing. Therefore, in order to avoid serious consequences caused by misoperation during simulation, general developers simply do not perform software simulation debugging, which affects the efficiency of code debugging. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to enable developers to perform simulation debugging of microprocessors in the state of grid-connected power equipment, and to enter various non-full-speed operation modes. [000...
