Problems solved by technology

[0003] In the inverter industry, traditional inverters do not have an upgrade function. When product iterations or bug fixes are performed, maintenance personnel can only disassemble the machine on site and upgrade the chip program through a dedicated programming tool, which is time-consuming and laborious. It also poses safety hazards

Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0023] refer to Figure 1 ~ Figure 3 As shown, the invention discloses a method for upgrading an inverter program.

[0024] In order to enable the inverter to have the upgrade function, during the inverter software development stage, it is necessary to plan the ARM chip and the Flash of the DSP chip in the inverter, and divide the boot program storage area and the application program storage area. The boot program storage area stores the bootloader program, which is responsible for program IAP processing and program jumping. The programs in this area generally do not change after leaving the factory; the application program stores programs related to actual functions, and this par...

Abstract

The invention relates to an inverter program upgrading method which comprises the following steps: S1, newly establishing an upgrading file, and transmitting the upgrading file to an ARM program of an inverter through a USB flash disk or a server; S2, enabling the ARM program to store the received upgrading file in an external flash; s3, reading parameters in an external flash, judging whether the ARM program needs to be upgraded or not, and if yes, starting upgrading of the ARM program; if not, not starting upgrading of the ARM program; s4, the ARM program being in communication connection with a DSP program in the inverter; and S5, reading parameters in the external flash, judging whether the DSP program needs to be upgraded or not, and if yes, sending an upgrading start instruction to the DSP through the ARM end to start upgrading of the DSP program. An ARM program or a DSP program in the inverter can be upgraded, maintenance personnel do not need to disassemble the machine on site, time and labor are saved, and the reliability is higher.

Description

technical field [0001] The present invention relates to the technical field of inverter program upgrade, in particular to an inverter program upgrade method. Background technique [0002] With the demand for green energy, the proportion of photovoltaic power generation in the field of electric energy is increasing, and the sales of inverters are increasing day by day, which brings great pressure to the maintenance of inverters. There is an urgent need for easy and simple maintenance. [0003] In the inverter industry, traditional inverters do not have an upgrade function. When product iterations or bug fixes are performed, maintenance personnel can only disassemble the machine on site and upgrade the chip program through a dedicated programming tool, which is time-consuming and laborious. At the same time bring security risks. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide an inverter program upgrade method, w...
