Problems solved by technology

[0004] However, the traditional processing method has the risk of burning software outflow. If the burning software is outflowed, criminals can use the hardware single-board copy board of frequency converter electronic products to "copy" the frequency converter, so that they can also copy the frequency converter without source code. The functions of this inverter can be used
Therefore, there are certain hidden dangers in the traditional method

Embodiment Construction

[0027] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0028] In one embodiment, such as figure 1 As shown, a safety verification method for inverter software programming is provided, including the following steps:

[0029] Step S110, programming the software of the frequency converter master and slave respectively.

[0030] The software programming in this step includes the program software programming in the programmable read-only storage space and the program software programming in the flash memory space. In the frequency converter, the master is generally the party that actively sends data, and the slave is generally th...

Abstract

This application relates to a method, device, storage medium and equipment for safety verification of inverter software programming, which performs software programming on the inverter master and slave respectively; performs master safety verification and slave safety verification operations; when the After the safety verification of the master and the safety verification of the slave are passed, the functions corresponding to the program software in the flash memory space of the master and the slave are executed. A safety check operation process is added inside the frequency converter, and only when the safety checks of the master machine and the slave machine pass, the functions corresponding to the program software in the flash memory space of the master machine and the slave machine can be executed. Even if criminals obtain the programming software, because they cannot obtain the program software programmed in the one-time programmable read-only storage space, they cannot complete the safety verification process of the frequency converter, so that they cannot use the functions of the program software programmed, and then Reduce the risk of outflow of programming software functions and improve the safety performance of the inverter.

Description

technical field [0001] The present application relates to the technical field of frequency converters, in particular to a safety verification method, device, storage medium and equipment for programming software of frequency converters. Background technique [0002] Inverter (Variable-Frequency Drive, VFD) is a power control device that changes the frequency and amplitude of the AC motor's operating voltage through variable frequency drive technology. With the development of inverter technology, its application range is becoming more and more extensive. [0003] During the use of the inverter, there are situations where it is necessary to adjust the software functions of the inverter according to the actual application scenario. The traditional method of adjusting the software function of the frequency converter is: the programming software generated after the embedded software is compiled is handed over to the on-site personnel for programming, or the on-site computer is re...
