The components of the embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the invention, as presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Example 1
A software and hardware verification method for a main control system of a wind generating set comprises the following steps:
s1, a main control program acquires a hardware serial number of a PLC module, and simultaneously acquires an MAC address of a development computer corresponding to the main control program;
s2, binding the hardware serial number with the MAC address;
s3, calculating the binding information according to an encryption algorithm to obtain an authorization code ciphertext;
s4, when the main control program starts to run, comparing the authorization code ciphertext with a prestored key file ciphertext;
s5, if the comparison is consistent, the software and hardware verification process is authorized to pass, and the main control program enters a formal running state; if the comparison is inconsistent, the main control program stops running.
Details concerning the above method steps will be described in detail in this embodiment.
The process of checking software and hardware of the main control system of the wind generating set can be divided into two parts, wherein one part is realized in a main control program, and the whole software and hardware checking authorization flow can be specifically referred to the schematic diagram of FIG. 1; the other part is the generation process of the cipher text of the key file by development assistance of a computer, and particularly, reference can be made to the schematic diagram of fig. 2.
In this embodiment, the PLC module corresponds to a hardware portion of the main control system of the wind turbine generator, and the main control program corresponds to a software portion of the main control system of the wind turbine generator.
The software and hardware verification authorization flow in the main control program can be realized by setting a software and hardware verification program module in the main control program.
The encryption and decryption processes can be realized through an encryption module arranged in the main control program, and the function aims to generate an authorization code ciphertext in the main control program and verify the authorization code ciphertext with a key file ciphertext; firstly, the main control program is developed by a corresponding development computer, and in the development process, the MAC address of the development computer is recorded in the main control program.
After loading the developed main control program into a PLC module of a main control system of the wind generating set, reading a hardware serial number of the PLC module when the main control program is ready to operate; and storing the hardware serial number under the path of the main control program in a text file mode.
And generating a corresponding authorization code ciphertext through a specific encryption algorithm according to the read hardware serial number and the MAC address of the development computer, thereby completing the whole encryption part.
In a preferred embodiment, the authorization code ciphertext generated at this time is stored in an internal variable of the main control program so as to be invisible to the outside.
Decrypting the cipher text of the key file required by decryption, wherein the cipher text is pre-stored in a path of the main control program in the process of checking software and hardware; the obtaining of the cipher text of the key file comprises the following steps:
s11, developing a key generation tool on a development computer corresponding to the main control program;
s12, the key generation tool reads the hardware serial number of the PLC module obtained by the main control program;
and S13, operating a key generation tool on the development computer according to the content of the hardware serial number, and calculating a key file ciphertext on the basis of an authorization code ciphertext by adopting an encryption algorithm which is the same as that in the main control program after the key generation tool acquires the MAC address of the development computer.
In the reading process in step S12, the hardware serial number of the PLC module obtained by the main control program in step S1 can be directly taken out, and then the key file ciphertext can be generated on the development computer by the key generation tool.
In this embodiment, the security requirement level for the ciphertext of the key file is higher, so when the key generation tool is operated on the development computer, the development computer needs to perform authority verification operation first, and only after verification is passed, the ciphertext of the key file is calculated and obtained; the arrangement ensures that only a person who owns the authority to operate the development computer can obtain the correct cipher text of the key file and complete the whole decryption process.
In the encryption and decryption processes, the related authorization code and key correlation algorithm can directly adopt a conventional algorithm in the general key encryption technology, and will not be described herein.
Finally, when comparing and checking the authorization code ciphertext with the key file ciphertext, if the authorization code ciphertext is inconsistent with the prestored key file ciphertext, the main control system enters a hardware check failure state, presents failure information, stops running of a program and waits for manual means to process; if the comparison is consistent, the main control program judges that the main control program is authorized, and enters a formal running state, and the PLC module is controlled to complete corresponding functional contents.
In summary, the embodiment is designed by a method, so that the hardware part and the software part of the main control system of the wind generating set are subjected to binding verification; meanwhile, the corresponding relation is further clear by binding the hardware serial number of the hardware part PLC module with the MAC address of the development computer; the key development tool developed on the development computer is used as another set of software to realize the decryption process, so that the verification safety and effectiveness between the PLC module and the main control software are ensured, and the corresponding software can be completely and smoothly operated on the corresponding hardware only if the verification is passed; therefore, the method of the embodiment brings a good solution to the problems of mismatching of software and hardware, control failure, misoperation and the like possibly existing in the main control system of the wind generating set, and achieves the due effect.
