BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Figure 2 A flowchart for entering text and image information for the present invention. DETAILED DESCRIPTION

[0025] In order to further illustrate the technical solution of the present invention, the present invention is further described below through embodiments.

[0026] like Figure 1 As shown, a provincial power grid company service bidding and procurement information entry and management system of this embodiment includes an image scanning information entry module, an information filling module, a database module, a feature information hierarchical management module, and an information retrieval module;

[0027] The image scanning information entry module is used to extract information from paper project information and digitally enter the paper project information; traditional report information is read through the image scanning information entry module, and historical paper bidding and procurement information is digitally entered, and it is equipped with an image information text extraction function, which uses the scanned image of the file to extract text and automatically identify relevant information.

[0028] The information filling module is used to manually supplement and correct the project information entered by the image scanning information entry module, and the user can also manually fill in the report information. If there is missing information in the image recognition process, the user can manually supplement the information. The information of the service bidding and procurement project is entered through the information filling module, and the information entered through the scanning information entry module is supplemented and corrected.

[0029] The database module is used to store the input item information of the information filling module.

[0030] The characteristic information hierarchical management module is used to hierarchically manage the input project information stored in the database module and set the access scope; during the information input process, the user performs hierarchical management of the information according to the project type of the input information, and the administrator account can set the access scope of the project information according to the importance and confidentiality of the project information. The service type, project amount, project progress, person in charge of the project department, winning enterprise and other information of the service bidding and procurement projects in the database are hierarchically managed, and the project information type is set to specify the access scope.

[0031] The information retrieval module is used to retrieve the project information entered into the database module; the user searches for information by selecting key project information such as project type, project name, project leader, etc. The classification basis is used to provide retrieval features, which facilitates the user to retrieve information.

[0032] Specifically, in the database module, the system adopts MySQL database for storage. First, a storage file original data information table is created in the database. According to the provincial power grid company's service bidding and procurement information, the data information is determined, including service type, project amount, project progress, person in charge of the project department, winning enterprise and other project file specific information, project information access permission identification information, and file path storage information. Users can customize the project file specific information and access permission identification information in the storage file original data information table.

[0033] The database construction process determines the database's authority address information, database service listening port number information, and database name information. The management platform communicates with the database through this database information.

[0034] When using the database module, the user uploads files using the UUID method to generate a unique identification file name for the stored file. During the file storage process, the user needs to fill in the specific information of the project and the access permission identifier.

[0035] When a user downloads a file during the use of the database module, the management system searches for the original data and path information of the saved file based on the file information selected by the user, and then the database module sends the file to the user.

[0036] The characteristic information hierarchical management module adopts the principle of least privilege and separation of sensitive data in the process of database construction, and determines the four levels of "public", "internal", "confidential" and "top secret" according to the confidentiality level of the service bidding and procurement information of the provincial power grid company. The confidentiality level is recorded by creating multiple tables to record the characteristics of the stored files at each level. According to the visitor account information, it is determined that the user can only upload and access the file information within the confidentiality level. The separate storage of sensitive data reduces the risk of leakage of confidential data.

[0037] When the characteristic information classification management module performs data classification management, employees apply for confidentiality access levels when registering account information. The application confidentiality level is reviewed and can be modified based on the administrator account. When employees upload and access downloaded files, the characteristic information classification management module determines whether to perform the operation by comparing the user's access content confidentiality level identification with the user's account confidentiality level restriction.

[0038] The information retrieval module adopts the original data retrieval method, and the user can enter or select specific information of the project file such as service type, project amount, project progress, person in charge of the project department, and winning enterprise for retrieval.

[0039] After the search content is submitted, the management system queries the original data information table of the database, removes information outside the access permission according to the characteristic information classification management module, and then returns all file information that meets the search information entered by the user.

[0040] like Figure 2 As shown, the text and image information input process of this embodiment includes two parts: paper document information input and user manual information filling.

[0041] For paper document information entry: first use the image acquisition device to collect the image information of the document, then use Gaussian filtering and binarization operations to process the image information, then use OCR technology to identify the wireframe information in the image, and identify the information based on the information inside and outside the frame and the standardized features of the power grid company's project files. After identifying the complete information, organize and store the information. For manual information filling by users: users can manually enter project information, and can also supplement and modify the automatically entered information.

[0042] The specific steps of using OCR technology are:

[0043] S1. In the process of collecting project information images, try to ensure the smoothness and standardization of the images;

[0044] S2, filter the noise in the image using Gaussian filtering;

[0045] S3, using binarization operation to process the Gaussian filtered image;

[0046] S4, detecting the wireframe region in the image using a wireframe region detection method;

[0047] S5. Identify the information outside the wireframe area. According to the standard format of the bidding and procurement information for the power grid company's services, the information outside the wireframe is mostly the project title. The identified information is used as the project name.

[0048] S6, dividing the wireframe area identified in the image into cells, and identifying the internal text information according to each cell, and arranging the table in a horizontal manner according to the standard format of the bidding and procurement information of the power grid company's service category, identifying the character coordinates and setting keywords to organize the text information in the image;

[0049] S7. After all the information is identified, the information is summarized and sorted.

[0050] Among them, the principle of image Gaussian filtering is as follows:

[0051] The image acquisition and transmission process will produce various noise effects in the image, resulting in reduced image quality. In the image noise, the generation of noise is random. In order to reduce the image noise in the training and prediction process using the image, and reduce the impact of image noise on the model's recognition of foreign objects, the present invention smoothes the image through Gaussian filtering. This method is very effective in suppressing noise that obeys a normal distribution. Gaussian filtering is actually a process of weighted averaging of the entire image. The value of each pixel is obtained by weighted averaging itself and other pixel values ​​in the neighborhood. The specific operation of Gaussian filtering is to use a convolution kernel (template) to scan each pixel in the image, and replace the value of the central pixel of the template with the weighted average grayscale value of the pixels in the neighborhood determined by the template. The calculation formulas for one-dimensional and two-dimensional convolution kernels are as follows:

[0052]

[0053]

[0054] Where (x, y) is the coordinate of the point, which can be regarded as an integer in image processing, and σ is the standard deviation. The first step of Gaussian filtering is to move the central element of the correlation kernel so that it is located directly above the pixel to be processed in the image. Secondly, the pixel value of the input image is used as the weight and multiplied by the correlation kernel. Finally, the results of the above steps are added as the output. The two important steps of Gaussian filtering are to find the Gaussian template and then perform the convolution operation.

[0055] The above embodiments are not limited to the technical solutions of the embodiments themselves, and the embodiments can be combined with each other to form new embodiments. The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Any modification or equivalent replacement that does not deviate from the spirit and scope of the present invention shall be included in the scope of the technical solutions of the present invention.
