本发明涉及信息领域，具体是指一种基于虚拟打印机的电子档案自动采集系统及采集方法。The invention relates to the field of information, in particular to an electronic file automatic collection system and collection method based on a virtual printer.
背景技术Background technique
随着学校信息化建设的不断发展，学校各部门电子文件的产生量日益巨大，大量的电子文件从各个管理与职能部门的业务系统中产生。电子文件和纸质文件的双套制管理模式，是档案工作的现行管理模式。比如说，教学是高校的主体，仅从教学这条线来讲，各层次学生基本信息及其在校其间的学籍信息，是教学类档案的重要组成部分。此类档案，在收集或采集时，均是每年均由本科生院、研究生院以及继续教育学院，通过自己的教务系统，向档案馆打印成纸质的来移交归档，但是其对应的电子文件，则都由档案馆在纸质文件归档后进行扫描加工，形成电子文件，再对外提供利用。由于数量大，整个扫描加工过程需要花相当的时间和人力才能完成，而且扫描过程中，对扫描质量的控制变得非常重要，对原始纸质档案的清晰度要求也高，这样扫描的结果才能符合利用的要求，其中的任何一个环节出现问题，都会对整体扫描质量直至最后的利用环节产生影响。With the continuous development of school information construction, the production of electronic documents in various departments of the school is increasing day by day, and a large number of electronic documents are generated from the business systems of various management and functional departments. The dual-set management mode of electronic files and paper files is the current management mode of archives work. For example, teaching is the main body of colleges and universities. From the perspective of teaching alone, the basic information of students at all levels and their student status information during school is an important part of teaching files. Such files, when collected or collected, are printed and handed over to the archives in paper form by the undergraduate school, graduate school, and continuing education college through their own educational affairs system every year, but the corresponding electronic files , are all scanned and processed by the archives after archiving the paper documents to form electronic documents, which are then provided for external use. Due to the large quantity, the entire scanning process takes considerable time and manpower to complete, and during the scanning process, the control of the scanning quality becomes very important, and the clarity requirements for the original paper files are also high, so that the scanning results can be If it meets the requirements of utilization, if there is a problem in any link, it will have an impact on the overall scanning quality until the final utilization link.
可见在实际归档前的电子文件不能被有效利用，导致档案馆收集纸质文件又须花费费用扫描成电子文件，成本高，效率低，而且扫描的质量又不能有效把控。It can be seen that the electronic files before the actual archiving cannot be effectively used, resulting in the archives collecting paper files and scanning them into electronic files at a cost, which is high in cost and low in efficiency, and the quality of scanning cannot be effectively controlled.

通过上述两种解决方法，用户非常方便的完成了实现电子文件的自动归档，以及形成相应的纸质文件。Through the above two solutions, the user can realize the automatic archiving of electronic files and the formation of corresponding paper files very conveniently.
(1)识别码(1) Identification code
为了档案管操作人员收集到纸质文件后，能够快速实现纸质文件与电子文件的归档过程，因此通常在生成通用格式的电子文件时，自动为该电子文件加入一个识别码。In order for archives operators to quickly realize the archiving process of paper documents and electronic documents after collecting paper documents, an identification code is automatically added to the electronic document when generating an electronic document in a common format.
识别码的形式可以是：一串文字、二维码图片、条形码图片，以及其它可支持特定设备识别的形式。The form of the identification code can be: a string of text, a picture of a two-dimensional code, a picture of a barcode, and other forms that can support specific device identification.
例如文字识别码，档案馆人员在归档纸质材料时直接输入这些文字即可快速检索到相应的电子文件。二维码、条形码图片，档案馆人员在归档纸质材料时可使用支持扫描二维码、条形码的设备快速检索到相应的电子文件。For example, the text identification code, the archives personnel can quickly retrieve the corresponding electronic files by directly inputting these texts when archiving paper materials. QR codes and barcode pictures, archives personnel can use devices that support scanning QR codes and barcodes to quickly retrieve corresponding electronic files when archiving paper materials.
(2)虚拟打印机(2) Virtual printer
虚拟打印机，就是虚拟的打印机，它是一种软件程式，模拟实现打印机的功能，打印文件。虚拟打印机同真实打印机一样，安装完毕后，打开“控制面板”中的“打印机和传真”，就会看到所安装的虚拟打印机，可以像使用一台打印机一样使用它们。鼠标双击将其打开，可以对其“打印首选项”和“属性”进行修改，从而设定是否共享、可使用时间、是否后台打印和优先级，以及纸张大小、版式安排等。它们同样能截获所有Windows程序的打印操作，或模拟打印效果，或完成某一特殊功能。A virtual printer is a virtual printer. It is a software program that simulates the functions of a printer and prints files. The virtual printer is the same as the real printer. After the installation is complete, open the "Printers and Faxes" in the "Control Panel", and you will see the installed virtual printers, and you can use them like a printer. Double-click it to open it, and you can modify its "Printing Preferences" and "Properties", so as to set whether to share, available time, whether to print in the background and priority, as well as paper size, layout arrangement, etc. They can also intercept the printing operation of all Windows programs, or simulate the printing effect, or complete a certain special function.
(3)身份认证(3) Identity authentication
身份认证通常采用以下几种方式：Identity authentication usually adopts the following methods:
i.用户输入账号及密码，然后网络请求至服务器端程式进行认证用户输入的账号及密码是否正确；i. The user enters the account number and password, and then the network requests to the server-side program to verify whether the account number and password entered by the user are correct;
ii.使用用户的数字证书；ii. Use the user's digital certificate;
iii.使用第三方身份认证平台；iii. Use a third-party identity authentication platform;
iv.其它身份认证方法；iv. Other identity authentication methods;
(4)通用格式的电子文件(4) Electronic files in common format
系统默认使用PDF作为通用格式。PDF全称Portable Document Format，译为"便携文档格式"，是一种电子文件格式。这种文件格式与操作系统平台无关，也就是说，PDF文件不管是在Windows，Unix还是在苹果公司的Mac OS操作系统中都是通用的。这一性能使它成为在Internet上进行电子文档发行和数字化信息传播的理想文档格式。同时PDF文件是以PostScript语言图象模型为基础，无论在哪种打印机上都可保证精确的颜色和准确的打印效果，即PDF会忠实地再现原稿的每一个字符、颜色以及图象。The system uses PDF as the common format by default. The full name of PDF is Portable Document Format, translated as "Portable Document Format", which is an electronic file format. This file format has nothing to do with the operating system platform, that is to say, PDF files are universal whether they are in Windows, Unix or Apple's Mac OS operating system. This performance makes it an ideal document format for electronic document distribution and digital information dissemination on the Internet. At the same time, PDF files are based on the PostScript language image model, which can guarantee accurate colors and accurate printing effects no matter what kind of printer is used, that is, PDF will faithfully reproduce every character, color and image of the original manuscript.
(5)加解密/网络传输(5) Encryption and decryption/network transmission
使用TCP/IP作为网络传输协议，同时使用HTTP协议作为数据传送协议，而且使用HTTP协议可以有效解决绕开防火墙。HTTPS是在HTTP之上的安全超文本传输协议。HTTPS应用了Netscape的完全套接字层(SSL)作为HTTP应用层的子层。SSL使用40位关键字作为RC4流加密算法。同时HTTPS和SSL也支持使用X.509数字认证。Use TCP/IP as the network transmission protocol, and use the HTTP protocol as the data transmission protocol, and use the HTTP protocol to effectively solve the problem of bypassing the firewall. HTTPS is Hypertext Transfer Protocol Secure over HTTP. HTTPS uses Netscape's Full Sockets Layer (SSL) as a sublayer of the HTTP application layer. SSL uses a 40-bit keyword as the RC4 stream encryption algorithm. At the same time, HTTPS and SSL also support the use of X.509 digital certificates.
SSL协议位于TCP/IP协议与各种应用层协议之间，为数据通讯提供安全支持。SSL协议可分为两层：SSL记录协议(SSL Record Protocol)：它建立在可靠的传输协议(如TCP)之上，为高层协议提供数据封装、压缩、加密等基本功能的支持。SSL握手协议(SSLHandshake Protocol)：它建立在SSL记录协议之上，用于在实际的数据传输开始前，通讯双方进行身份认证、协商加密算法、交换加密密钥等。The SSL protocol is located between the TCP/IP protocol and various application layer protocols, providing security support for data communication. The SSL protocol can be divided into two layers: SSL Record Protocol (SSL Record Protocol): It is built on a reliable transmission protocol (such as TCP) and provides support for basic functions such as data encapsulation, compression, and encryption for high-level protocols. SSL Handshake Protocol (SSLHandshake Protocol): It is built on the SSL record protocol and is used for identity authentication, negotiation of encryption algorithms, and exchange of encryption keys before the actual data transmission begins.
因此，使用HTTPS为客户端与服务器端之间的网络传输起到如下作用：Therefore, using HTTPS plays the following roles for network transmission between the client and the server:
I认证用户和服务器，确保数据发送到正确的客户机和服务器；I authenticate users and servers to ensure that data is sent to the correct client and server;
Ii加密数据以防止数据中途被窃取；Ii encrypts data to prevent data from being stolen;
Iii维护数据的完整性，确保数据在传输过程中不被改变。Iii maintains the integrity of the data, ensuring that the data is not altered during transmission.
(6)加工、数据分析(6) Processing and data analysis
系统针对档案归档业务需求提供以下几个主要的处理功能。The system provides the following main processing functions for the archives business requirements.
A.OCR识别与模式匹配A. OCR recognition and pattern matching
通过虚拟打印机接管请求打印的电子原件，如果为图像，则经过OCR识别技术自动识别出中文，同时结合模式库对这些中文进行抽取元数据。如果为其它格式的文档，则结合模式库对这些文档进行抽取元数据。The electronic original requested to be printed is taken over by the virtual printer. If it is an image, it will automatically recognize Chinese through OCR recognition technology, and at the same time extract metadata from these Chinese in combination with the pattern library. If it is a document in other formats, the metadata is extracted from these documents in combination with the pattern library.
OCR识别可以使用Tesseract的OCR引擎。Tesseract的OCR引擎最先由HP实验室于1985年开始研发，至1995年时已经成为OCR业内最准确的三款识别引擎之一。Tesseract目前已作为开源项目发布在Google Project。OCR recognition can use Tesseract's OCR engine. Tesseract's OCR engine was first developed by HP Labs in 1985, and by 1995 it had become one of the three most accurate recognition engines in the OCR industry. Tesseract is currently published as an open source project on Google Project.
模式库主要有几种类型。一种类型是在识别出中文的基础上，根据出现的前后顺序建立的模板。另一种类型是基于元数据出现的XY位置而建立的模板。另外就是根据特定文档通过外挂程式进行准确抽取元数据。通过这些模板对电子原件进行元数据分析，抽取元数据信息。如发文，则元数据有发文的主题、发文单位、文号、日期等。如成绩信息，则有学生姓名、年级、班级、学号、学期等。还有一种类型是基于语义进行识别。There are several main types of pattern libraries. One type is a template established according to the order of appearance on the basis of recognizing Chinese. Another type is a template based on the XY position where the metadata occurs. The other is to accurately extract metadata through plug-ins based on specific documents. Perform metadata analysis on electronic originals through these templates, and extract metadata information. If a document is published, the metadata includes the subject of the document, the issuing unit, document number, date, etc. Such as grade information, there are student names, grades, classes, student numbers, semesters, etc. There is another type of recognition based on semantics.
B.生成识别码B. Generate an identification code
在生成通用格式的电子文件时，自动为该电子文件加入一个识别码。识别码的形式支持文字、二维码、条形码等。When an electronic file in a common format is generated, an identification code is automatically added to the electronic file. The form of the identification code supports text, two-dimensional code, bar code, etc.
C.服务器端文件存储及管理C. Server-side file storage and management
支持按部门定义文件夹，使得电子文件自动归属到相应的部门文件夹下；Support for defining folders by department, so that electronic files are automatically assigned to the corresponding department folders;
支持自定义电子文件自动生成名称；Support automatic generation of names for custom electronic files;
支持按元数据项进行检索与二次检索；Support retrieval and secondary retrieval by metadata item;
支持根据电子文件匹配的模板进行自动分类，如发文、学籍卡等；Supports automatic classification based on templates matched with electronic documents, such as posting documents, student status cards, etc.;
支持文件压缩与加密存储；Support file compression and encrypted storage;
支持二维码检索；Support QR code retrieval;
支持电子公章和电子签名章的应用；Support the application of electronic official seal and electronic signature seal;
支持WS接口方式及XML方式电子文件批量导出；Support batch export of electronic files in WS interface mode and XML mode;
支持电子文件的全量备份、增量备份、异机备份等多种形式；Support various forms such as full backup, incremental backup, and different machine backup of electronic files;
支持对特异性数据来源的元数据分析功能；Support metadata analysis functions for specific data sources;
支持管理与上传电子文件模板(即为模式库)；Support management and upload of electronic file templates (that is, pattern libraries);
支持扩展数据接口，使与纸质材料二维码相对应的电子文件、归档附加信息等传递到“预立卷系统”或“数档系统”。Support extended data interface, so that the electronic files corresponding to the QR codes of paper materials, additional information for filing, etc. can be transmitted to the "pre-volume system" or "digital file system".
D.其它功能模块D. Other functional modules
如图3所示描述了实际兼职档案员操作的应用模型。兼职档案员针对需打印生成的纸质归档原件，通过系统上述步骤形成相应的电子文件及纸质材料。另外针对对于已存在的纸质归档实体与对应电子文件，通过适度改进业务系统，使系统能够获取相应目录数据信息及其电子文件，这些作为主体归档材料，同时业务办理过程形成的过程信息与过程文件，仍然可以通过系统上述步骤，打印生成业务过程纸质原件与电子文件。As shown in Figure 3, the application model of the actual part-time archivist operation is described. The part-time archivist will form corresponding electronic files and paper materials through the above steps of the system for the original paper archives that need to be printed. In addition, for the existing paper archiving entities and corresponding electronic files, by moderately improving the business system, the system can obtain the corresponding catalog data information and electronic files, which are used as the main archiving materials, and the process information and process formed during the business process Documents can still be printed to generate paper originals and electronic documents in the business process through the above steps of the system.
