S1. Create a new txt document, and list the key information recorded in the document as a matching item;

S2, create a new VI program based on Labview to read the above txt file and convert it into a two-dimensional array;

S3. Receive the information input by the user, and use the above information as the item to be matched, apply the loop program of Labview and the if-else judgment program to match the item to be matched with the matching item in the two-dimensional array, and according to the key information of successful matching The number of different permissions assigned to the user.

Preferably, in step S1, the key information recorded in the document includes: user name, password, position.

Preferably, step S3 specifically includes:

Match the item to be matched with the matching item in the row and column of the two-dimensional array, and record the number of matching items that are successfully matched, and assign different permissions to the user according to the above number.

The permission login system based on Labview that the present invention proposes comprises:

The document creation module is used to create a new txt document and list the key information recorded in the document as matching items;

The array conversion module is used to create a new VI program based on Labview to read the above txt file and convert it into a two-dimensional array;

The authority distribution module is used to receive the information input by the user, and use the above information as the item to be matched, apply the loop program of Labview and the if-else judgment program to match the item to be matched with the matching item in the two-dimensional array, and according to the matching The number of successful key information assigns different permissions to users.

Preferably, in the document creation module, the key information recorded in the document includes: user name, password, and position.

Preferably, the authority assignment module is specifically used for:

Match the item to be matched with the matching item in the row and column of the two-dimensional array, and record the number of matching items that are successfully matched, and assign different permissions to the user according to the above number.

The present invention first records the key information into a txt file, and then uses the Labview software function to convert the txt file into a two-dimensional array, which facilitates subsequent information matching operations, and then based on the Labview software function, the key information in the two-dimensional array and the user input Match the information, and finally assign permissions to users according to the matching results, which not only improves the pertinence of permission assignment, but also ensures the security of user identity verification. In addition to the Labview software, the present invention does not need to install other software, and also avoids original and complicated processes such as databases and codes. The expected effect can be achieved by using txt files, and information can be easily changed at any time, and this method is beneficial to users and equipment. The requirements have been reduced, which is more convenient for users to use.

detailed description

As shown in Fig. 1 and Fig. 2, Fig. 1 and Fig. 2 are a Labview-based authority login method and system proposed by the present invention.

With reference to Fig. 1, a kind of permission login method based on Labview that the present invention proposes, comprises the following steps:

S1. Create a new txt document, and list the key information recorded in the document as a matching item;

In this embodiment, the key information recorded in the document includes: user name, password, and position; by recording the above-mentioned basic information, it can provide a verification basis for verifying the user's identity and authority, and ensure the pertinence of the above-mentioned verification process and security.

Further, the key information recorded in the document can also be customized according to the user's actual use requirements, so as to perform targeted switching according to the user's actual use scenarios and environments, thereby improving the scope and effect of the method.

S2. Create a VI program based on Labview to read the above txt file and convert it into a two-dimensional array; wherein, the row and column information of the two-dimensional array is arranged according to the key information recorded in the txt file.

S3. Receive the information input by the user, and use the above information as the item to be matched, apply the loop program of Labview and the if-else judgment program to match the item to be matched with the matching item in the two-dimensional array, and according to the key information of successful matching The number of different permissions assigned to the user.

In this embodiment, step S3 specifically includes:

Match the items to be matched with the matching items in the rows and columns of the two-dimensional array, and record the number of successfully matched items, and assign different permissions to the user according to the above number; to judge the user based on the information entered by the user different identities, and then assign different permissions to users according to their different identities to ensure the security of user identity verification. Pertinence, while simplifying the user's authentication process and improving the user's experience.

With reference to Fig. 2, Fig. 2 is a kind of permission login system based on Labview that the present invention proposes, including:

The document creation module is used to create a new txt document and list the key information recorded in the document as matching items;

In this embodiment, in the document creation module, the key information recorded in the document includes: user name, password, and position; by recording the above-mentioned basic information, it can provide a verification basis for verifying the user's identity and authority, and ensure the above-mentioned Pertinence and security of the verification process.

Further, the key information recorded in the document can also be customized according to the user's actual use requirements, so as to perform targeted switching according to the user's actual use scenarios and environments, thereby improving the scope and effect of the method.

The array conversion module is used to create a VI program based on Labview to read the above txt file and convert it into a two-dimensional array; wherein, the row and column information of the two-dimensional array is arranged according to the key information recorded in the txt file.

The authority distribution module is used to receive the information input by the user, and use the above information as the item to be matched, apply the loop program of Labview and the if-else judgment program to match the item to be matched with the matching item in the two-dimensional array, and according to the matching The number of successful key information assigns different permissions to users.

In this embodiment, the authority allocation module is specifically used for:

Match the items to be matched with the matching items in the rows and columns of the two-dimensional array, and record the number of successfully matched items, and assign different permissions to the user according to the above number; to judge the user based on the information entered by the user different identities, and then assign different permissions to users according to their different identities to ensure the security of user identity verification. Pertinence, while simplifying the user's authentication process and improving the user's experience.

In this embodiment, the key information is first recorded in a txt file, and then the txt file is converted into a two-dimensional array using the Labview software function to facilitate subsequent information matching operations, and then the key information in the two-dimensional array and the user input are based on the Labview software function. According to the matching information, users are assigned permissions according to the matching results, which not only improves the pertinence of permission allocation, but also ensures the security of user identity verification.
