I. Overview
1.1
Background of the project
In the current era of intelligent information technology, the most important thing for archivists is to think about how to “manage” and “use them well.” To “manage” archives well is to build an intelligent archive that can adapt to the era of intelligent information technology. To “use well” archives is to build an archive that provides user-centric services in a big data environment. If archival data is “fish”, the previous archival work model is equivalent to “pond fishing”. In the era of big data, archival departments face a large number of files and a wide variety of types. The work mode must be more flexible and intelligent. Otherwise it is equivalent to “fishing in the sea”. Therefore, the construction of smart archives is so important. The core concept of intelligent archives is intelligent services. To provide intelligent services, archives must unify the premises, archives, network, data, and users in the intelligent network to achieve effective mining, integration, and utilization of the nautical mile structure generated by various interactive elements. The purpose of structuring and unstructured data.
Under normal circumstances, after the implementation of RFID technology in archives, with the same number or fewer librarians, the quality of information management of archives will be greatly improved. At present, many provincial archives in China have implemented RFID systems and have started to use them steadily. Units such as State Grid, the courts, industry and commerce, and the talent market are also in the process of piloting. In the future, more RFID intelligent archives will enter the implementation stage.
1.2
Current status of archives
At present, domestic archives have insufficient management capabilities. After summarizing, there are roughly the following problems:
※ File management mostly stays at the stage of visual management
※ There is a general lack of automatic identification methods, which is not conducive to the development of inventory work
※ Archives generally lack an accurate grasp of the presence and location of physical archives
※ There is no way to know exactly whether the files are in the library, etc., and there is a lack of safety management mechanism
※ The file cataloging process is cumbersome and inefficient, and it takes a long time to organize
※ File review takes a long time, and the accuracy of review is difficult to meet the requirements
※ The order of file storage is easy to be disrupted, and it is difficult to find if it is put in the wrong place
※ The file inventory operation is unscientific ※ The utilization rate of public files is not high
※ File confidentiality work still relies too much on manual work, the confidentiality is poor, and the risk is high
※ File loss prevention work lags behind, and many precious files are damaged or lost
※ The management of expired files is lagging behind, and the destruction of expired files is not timely
※ File flow management is chaotic, and frequent loss and file disconnection occur
1.3
Introduction to RFID
RFID is the core technology of the system construction project, using RFID radio frequency identification technology. RFID radio frequency identification technology is the core basic technology of the Internet of Things application technology. The principle of this technology is to use the RFID transmitter to emit radio waves, activate the RFID tag oscillation circuit, generate current, and then read and write the stored information in the chip. Identity recognition technology is a new practical technology oriented to the 21st century. In terms of technical application, it carries a large amount of information, does not require contact recognition, can read multiple tags at a time, and has high reading and writing speed. It is becoming more and more popular in the society. The recognition of RFID and is replacing barcode and magnetic stripe technology. Compared with barcode and magnetic stripe technology, RFID tags have absolute advantages. The comparison is as follows:
Quick scan:Only one barcode can be scanned at a time; the RFID reader can identify and read several RFID tags at the same time.
Small size and diversified shapes:RFID is not limited by size and shape in reading, and does not need to match the fixed size and printing quality of the paper for reading accuracy. In addition, RFID tags can be miniaturized and developed in various forms to be applied to different products.
Anti-pollution ability and durability:The carrier of traditional bar codes is paper, so it is susceptible to contamination, but RFID is highly resistant to substances such as water, oil, and chemicals. In addition, because the bar code is attached to the plastic bag or the outer packaging carton, it is particularly vulnerable to breakage; RFID tag stores the data in the chip, so it can be protected from contamination.
reusable:Nowadays, the barcode cannot be changed after it is printed, and the RFID tag can repeatedly add, modify, and delete the data stored in the RFID tag to facilitate the update of information.
Penetrating and barrier-free reading:When covered, RFID can penetrate non-metallic or non-transparent materials such as paper, wood, and plastic, and can perform penetrating communication. The barcode scanner must be at a close distance and there is no object blocking the situation before it can read the barcode.
Large data memory capacity:The capacity of a one-dimensional bar code is 50 Bytes, the maximum capacity of a two-dimensional bar code can store 2 to 3000 characters, and the maximum capacity of an RFID is several MB. The current general RFID tag capacity is 1K. With the development of memory carriers, the data capacity also has a trend of continuous expansion. In the future, the amount of information that items need to carry will become larger and larger, and the demand for the expansion of the capacity of the label will also increase accordingly.
safety:Since RFID carries electronic information, its data content can be protected by a password, so that its content is not easy to be forged and altered.
1.4
Significance of constructing RFID intelligent archives collection management system
At present, archives basically use manual methods to count archive data, which can easily lead to file loss and data confusion. More advanced archives use barcode technology as an identification method to achieve these functions. However, although barcodes are cheap and easy to make, they also have some inherent shortcomings that are difficult to overcome, such as easy wear, small storage space, and inconvenience to the use of books, which are not completely suitable for archives. RFID intelligent management will bring the following advantages and meanings:
(1) Resources can be reasonably allocated
RFID intelligent management transforms the work of archives from manual file registration search to RFID automatic file search, allowing managers to find the resources they need in the shortest time.
(2) Efficient use of resources
RFID intelligent management makes the cumbersome work originally undertaken by the administrators lighter, and the manpower expenditure of the archives is correspondingly reduced, and the cost is reduced accordingly. Archivists use the saved time and human resources to extend the opening hours of the archives, for deeper reference and consulting work and personalized services, so as to increase the utilization rate of the archives.
(3) Safety is greatly improved
1) RFID tags have a globally unique identifier and cannot be copied;
2) If the label is torn down, there will be an alarm prompt;
3) Equipped with anti-theft device to avoid illegal removal of files;
4) Real-time monitoring of file status, abnormal alarm;
5) Automatic statistics to avoid human error;
6) Automatic reminder of file borrowing expiration;
7) Automatic reminder when the file storage period expires;
8) Real-name registration for file borrowing and return, and permanent storage of operating data.
Two, the solution
2.1
customer demand
Archives management is an important aspect of the application of RFID technology, and archives are the most concentrated application places for archives management needs. Based on the RFID archive management system using radio frequency identification RFID technology, archive managers can operate archives in any warehouse, and archives will be transferred anytime and anywhere with electronic digital tags. Self-service transfer of archives and the emergence of return on shelves, especially if it can do more at once This allocation and intelligently put on shelves according to the path greatly saves the workload of librarians and the waiting time of archives allocation personnel. RFID can better improve the efficiency of archives circulation management and collection management, so that archives administrators can have more time to provide services for archives transfer personnel, and bring new opportunities for the development of archives industry.
