ETC (Electronic Toll Collection) is an automatic Toll Collection for highways or bridges. The special short-range communication is carried out between the vehicle-mounted electronic tag arranged on the vehicle windshield and the microwave antenna on the ETC lane of the toll station, and the computer networking technology and the bank are utilized to carry out background settlement processing, so that the purpose that the vehicle can pay the highway or bridge expenses through the highway or bridge toll station without parking is achieved.
At present, ETC invoice information can be acquired only through applying to generate toll electronic invoices through a toll road toll electronic invoice service platform (hereinafter referred to as ETC platform, namely a ticket root network), registration and login are required during application, a license plate number is required to be input after login, multiple items of information such as month printing and the like are selected, the electronic invoices can be generated and sent to an electronic mailbox after verification is correct, and the ETC invoices of different vehicles cannot be downloaded in batches.
Some large-scale enterprises and public institutions usually have nearly hundreds of buses, invoices need to be printed through ETC platforms, the operations are repeatedly carried out on each bus every month, and the downloaded invoices are only in PDF documents, so that the invoices are not convenient to file and count and gather. After downloading the toll invoice from the ETC platform, need according to the requirement manual statistics of financial affairs information in the ETC invoice for invoice verification and statistics work, this part is consuming time power, and the probability that manual operation made mistakes is very big.
Based on the method, the embodiment of the invention provides an ETC invoice automatic summarizing method and device.
The following is a detailed description of an embodiment of an automatic aggregation method for ETC invoices according to an embodiment of the present invention.
Referring to fig. 1, the present embodiment provides an automatic collection method for ETC invoices, including:
s101: and downloading the invoice information in the PDF format from the ETC platform, and storing the invoice information in the PDF format into a preset cache path.
It should be noted that, the invoice information in the PDF format may be downloaded from the ETC platform by a JAVA virtual machine. Specifically, information such as license plate numbers, passing months and the like and login information are input on a JAVA virtual machine, and the JAVA virtual machine automatically logs in an ETC platform to download corresponding invoice information.
S102: scanning a preset cache path, and detecting whether a new PDF file exists.
It should be noted that there may be two scanning modes for the preset cache path.
The first is a boot scan mode, in which a predetermined cache path is scanned after each boot. The second is a timed scan mode, that is, a preset cache path is scanned according to a preset time.
S103: if yes, the picture file converted from the PDF file is extracted, and if not, step S103 is repeated.
Since the content in the PDF is generally composed of picture information, a picture file can be obtained by storing the PDF as the picture information.
S104: and acquiring the coordinate position of the information to be extracted according to the preset invoice template information.
It should be noted that the preset invoice template is set through the existing ETC toll invoice, the existing invoice has a uniform format, and different invoicing information is displayed at different fixed positions of the invoice, for example, province information (Shandong value-added tax electronic common invoice) with invoicing is displayed at a head-up position of the invoice by a larger word number, and information such as an invoice code, an invoice number, an invoicing date and a check code is displayed at the upper end of the right side of the invoice.
In the text of the invoice, more invoicing information is displayed in a form of a table, such as information of the invoicer, the name of the item, the license plate number, the passing date, the amount of money, the tax rate and the like.
The above information is in a fixed position in the same size picture, that is, the same information has the same coordinate position in the picture of the invoice in different invoices.
In this embodiment, the required billing information is selected from the template in advance, and the coordinate range of the billing information in the invoice picture is acquired. Specifically, a rectangular frame range corresponding to the required billing information is obtained first, and then a coordinate position corresponding to the rectangular frame range is extracted.
S105: and extracting a plurality of sub-picture files from the picture file according to the coordinate position.
It should be noted that, for each piece of required billing information, a sub-picture in a picture corresponding to the coordinate information may be extracted according to the preset corresponding coordinate information.
S106: and performing character recognition on each sub-picture file, and extracting corresponding character contents.
It should be noted that, the text content on each sub-picture may be recognized by the existing OCR text recognition technology to obtain each sub-billing information, where the sub-billing information may include information such as a billing province, a drawer information, a license plate number, a passage date, and an amount.
S107: and combining the text content corresponding to each sub-picture file into a piece of billing information data, and inserting the billing information data into a preset statistical table.
It should be noted that the statistical table may be a proprietary database file or an EXCEL table.
In the statistical table, the key value of each column is the billing sub-information, when inserting, one piece of billing information data is taken as a line, and the relevant billing sub-information is inserted into the statistical table according to the difference of the billing sub-information corresponding to the key value of each column.
In some preferred examples, it is also stored by different tables for different months. And when detecting that the statistical table of the current month does not exist, taking the current month as a main body, and creating a new statistical table.
In other examples, different license plate numbers, different invoicing provinces and the like can be processed by a similar method to obtain different types of statistical tables so as to facilitate checking.
Further, after the corresponding billing information is obtained, the PDF file in the cache path can be deleted periodically, so that the condition that the storage space is occupied due to excessive PDF files is avoided.
The embodiment provides an automatic summarizing method of ETC invoices, which comprises the steps of downloading invoice information in a PDF format from an ETC platform, and storing the invoice information in the PDF format into a preset cache path; scanning a preset cache path, and detecting whether a new PDF file exists; if yes, extracting a picture file converted from the PDF file; acquiring the coordinate position of the information to be extracted according to preset invoice template information; extracting a plurality of sub-picture files from the picture file according to the coordinate position; performing character recognition on each sub-picture file, and extracting corresponding character contents; and combining the text content corresponding to each sub-picture file into a piece of billing information data, and inserting the billing information data into a preset statistical table.
According to the method for collecting the toll invoices in the PDF format, the toll invoicing information needing to be extracted in the toll invoices is identified through the preset invoice template information through automatic downloading of the toll invoices in the ETC platform, and the extracted information is automatically classified and stored. The invoice verification and statistics work is carried out by financial staff conveniently, the statistics time is saved, the error probability is small, and the high error rate of manual statistics is avoided.
