Detailed Description
Other advantages and effects of the present invention will become apparent to those skilled in the art from the following disclosure, which describes the embodiments of the present invention with reference to specific examples. The invention may be practiced or carried out in other embodiments that depart from the specific details, and the details of the present description may be modified or varied from the spirit and scope of the present invention.
As shown in fig. 1, the method for generating the trusted fixed value list of the secondary equipment of the power system comprises the following steps:
s1: acquiring an operation fixed value list picture, an approval fixed value list picture and an authorization fixed value list picture; and the same fixed value sheet template is used for filling the fixed value data by the running fixed value sheet, the checking fixed value sheet and the authorization fixed value sheet.
S2: performing character recognition on the operation fixed value single picture, the approval fixed value single picture and the authorization fixed value single picture, and extracting corresponding fixed value data; if the authorization fixed value list picture is inconsistent with the operation fixed value list picture and the fixed value data extracted by the check fixed value list picture, continuing to execute the step S3;
s3: performing image similarity analysis on the check value sending single picture and the authorization value sending single picture; if the preset condition is met, the authorized fixed value list picture is used as a trusted fixed value list picture to be stored in a fixed value list library; otherwise, a warning prompt is sent out.
When the step S1 is implemented, if an operation fixed value list picture is required, the operation fixed value list is firstly obtained, fixed value data put into operation by the secondary equipment can be acquired or read through a data acquisition device of the secondary equipment, then the read fixed value data is processed in a certain format and then is imported into a fixed value list template, so that the operation fixed value list is obtained, and then the operation fixed value list is converted into a picture file through a picture conversion tool, so that the operation fixed value list picture is obtained.
The approval value list picture is converted into a picture file by an approval value list, and the approval value list can be obtained only by inputting fixed value data calculated by the setting into a fixed value list template; however, since the approval value sheet is editable, it is necessary to convert the approval value sheet into a picture file, and the difficulty of tampering is increased.
The authorization value list picture is converted into a picture file by the authorization value list, and the authorization value list is actually a transmitted and checked value list which is checked by an auditor. Generally, the authorized value list picture is converted into a picture file to prevent tampering.
In the invention, the same fixed value single template is used for filling the fixed value data by running the fixed value single, transmitting the check fixed value single and authorizing the fixed value single. In general, the power supply mechanism will set up a fixed value form template, i.e. design a word or Excel fixed value form template, so the fixed value form template is electronic and editable. Furthermore, importing external data into word or Excel may be implemented through development tools of word or Excel. As shown in fig. 2, the content formats of the running order, the delivery order and the authorization order in the present invention are consistent, that is, the content format of the template of the order shown in fig. 2 is adopted. The invention converts the operation fixed value list, the transmission check fixed value list and the authorization fixed value list into the picture file, so that the data cannot be directly edited, and the credibility of the data can be improved.
When the step S2 is implemented, characters in the pictures are converted into a text format by adopting an OCR (optical character recognition) technology, the extraction of the character information in the pictures is completed by combining with word processing software, and then the fixed value data of each fixed value single picture is obtained by combining with the configuration file of the fixed value single template.
However, because the OCR technology has a certain misreading rate, the defect of the OCR technology accuracy is overcome by the design of redundancy judgment, that is, judging whether the operation fixed value single picture is consistent with the approval fixed value single picture and whether the fixed value data between the operation fixed value single picture and the authorization fixed value single picture is consistent. If the operation fixed value single picture is consistent with the fixed value data of the approval fixed value single picture or the operation fixed value single picture is consistent with the fixed value data of the authorization fixed value single picture, the approval fixed value single or the authorization fixed value single can be considered to be credible without continuously executing the step S3; if the fixed value data of the operation fixed value single picture and the fixed value data of the approval fixed value single picture are inconsistent, and the fixed value data of the operation fixed value single picture and the fixed value data of the authorization fixed value single picture are inconsistent, the approval fixed value single or the authorization fixed value single is not credible at the moment, namely, the step S3 is needed to be entered.
In the implementation of the step S3, a preset condition is set, such as how much proportion the similarity needs to reach. In addition, the invention adopts a histogram comparison method or a characteristic point matching algorithm to analyze the image similarity.
In a specific embodiment, in order to further ensure the credibility of the authorized value order picture, before the authorized value order picture is stored as a credible value order picture in the value order library, the following steps are executed:
the method comprises the steps that firstly, difference area images are extracted from an operation fixed value single picture and an approval fixed value single picture, so that a plurality of pairs of difference area images are obtained;
secondly, carrying out character recognition on a plurality of pairs of difference area images, and extracting a plurality of pairs of difference constant value data;
thirdly, taking a plurality of pairs of difference constant value data as analysis objects, and performing multi-target fuzzy comprehensive analysis to obtain recommended constant value data;
step four, respectively calculating deviation indexes of the fixed value data of the transmitted check value single picture, the authorized fixed value single picture and the recommended fixed value data; if the deviation index corresponding to the authorized value list picture is smaller, importing the value data corresponding to the authorized value list picture into the secondary equipment to modify the value data of the secondary equipment; otherwise, a warning prompt is sent out.
In the first step, in implementation, it is necessary to divide the two aligned fixed-value single pictures into a plurality of picture areas in the same manner, for example, divide the picture areas in the form of pixel ranges. Then, by analyzing the similarity of each pair of picture areas one by one, a difference area between the picture files is extracted. Meanwhile, in the first step, a fixed value item corresponding to each difference area image is determined according to a fixed value item position matching file pre-configured by the fixed value single template; the method is convenient for the second step to be convenient for associating with the corresponding constant value item when the difference constant value data is extracted in the subsequent step; the use principle of the fixed value item position matching file is as follows: because the content format of the constant value single template is determined, after the constant value single template is converted into the picture file, the data of each constant value item is certainly presented in a certain pixel range of the picture file, and therefore, each image area is associated with the constant value item contained in each image area by calibrating the pixel range corresponding to each constant value item.
And the second step and the third step can also exchange and combine the constant value item data of two differences of the same constant value item between the picture files to form the difference result set. For example, the operation fixed value single picture and the approval fixed value single picture have three difference areas, and the data of the operation fixed value single picture in the difference areas are respectively: A. b and C, the data of the single picture of the approval value in the difference area are respectively as follows: D. e and F, then an additional 6 data combinations can be obtained by exchange combination of the constant value item data.
By expanding the difference data combination, the invention can provide more analysis objects for fuzzy comprehensive analysis, thereby reducing the influence of weight distribution in an analysis algorithm on analysis results. Besides, the invention can adopt clustering analysis to obtain recommended value data besides fuzzy comprehensive analysis.
In the fourth step, in implementation, the deviation index is specifically related to the data of the constant value item and also related to the risk coefficient of the power system caused by the change of the numerical value of the constant value item, so that the risk coefficient corresponding to the constant value item is taken as the weight value and is incorporated into the calculation of the deviation index, and the influence on the credibility of the constant value data based on the consideration of safety can be realized.
