Description

An RFID-based file storage management system Technical Field

[0001] This invention relates to the field of radio frequency identification technology, and more specifically to an RFID-based file storage management system. Background Technology

[0002] RFID, short for Radio Frequency Identification, is a type of automatic identification technology. It uses radio frequency (RF) for non-contact, two-way data communication, reading and writing data onto a recording medium (electronic tag or RFID card) to identify targets and exchange data. It is considered one of the most promising information technologies of the 21st century. RFID has a wide range of applications, including animal microchips, car anti-theft devices, access control, parking management, production line automation, and material management. RFID technology uses radio waves for rapid, non-contact information exchange and storage. Through wireless communication combined with data access technology, it connects to a database system to achieve non-contact, two-way communication, thus achieving identification and data exchange, creating a highly complex system.

[0003] With the widespread adoption of networking and the application of electronic management, traditional management methods are gradually being replaced by electronic document management systems to meet the needs of data-driven document management in enterprises. These systems monitor, borrow, and return documents, thereby improving enterprise management efficiency. However, common document management systems using RFID technology directly bind electronic tags to documents. Therefore, when documents are lost or need updating, the electronic tags must be reset, impacting normal work efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide an RFID-based file storage management system to solve the following technical problems:

[0005] In conventional RFID-based document management systems, the frequent setting of electronic tags leads to low work efficiency.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] An RFID-based document storage management system includes a filing cabinet with several storage spaces for holding physical documents, and further includes:

[0008] The tag configuration module includes several electronic document tags and electronic wake-up tags. The electronic document tags are set in each storage space and bound to the storage space; the electronic wake-up tags are bound to employees.

[0009] The information acquisition module obtains the location coordinates of the storage space and the feature information of the physical archives. The feature information includes the name, author, and high-frequency words in the physical archives.

[0010] A primary reader / writer is used to emit radio frequency energy to form an electromagnetic field. The effective area of ​​the electromagnetic field is a spherical region centered on the filing cabinet, and the radius of the spherical region is a preset fixed value. The position coordinates, file status information, and feature information are entered into the corresponding electronic file tag. The file status information includes borrowing and storing.

[0011] The document management module includes a secondary reader / writer and a database. The database stores the characteristic information of physical documents and the IDs of their corresponding electronic document tags. It obtains borrowing requests and retrieves the IDs of the electronic document tags corresponding to the physical documents to be borrowed through database retrieval. The secondary reader / writer then inputs the IDs of the electronic document tags into the electronic wake-up tag. The borrowing request includes keywords, file name, and author.

[0012] As a further aspect of the present invention: the electronic document tag remains in a dormant state when it does not receive a communication request from the reader, and only the data storage portion of the electronic document tag is active while in the dormant state.

[0013] As a further aspect of the present invention: when the electronic wake-up tag enters the effective area, the reader reads the ID of the electronic file tag in the electronic wake-up tag, wakes up the designated electronic file tag, and changes the file status in the electronic file tag to "borrowed".

[0014] As a further aspect of the present invention: the file management module further includes:

[0015] Upon receiving a save request, the identification code is entered into the electronic wake-up tag via a secondary reader. After reading the identification code in the electronic wake-up tag, the primary reader wakes up the corresponding electronic file tag and changes the file status in the electronic file tag to save.

[0016] As a further aspect of the present invention: during the borrowing process, if the file status in the electronic file tag is "borrowed" after the reader wakes up the designated electronic file tag, the borrowing is determined to have failed.

[0017] As a further aspect of the present invention: during the document borrowing process, the primary reader changes the document status in the electronic document tag to "borrowed," reads the location coordinates in the electronic tag, and displays them to the employee through a display device.

[0018] As a further aspect of the present invention: the secondary reader communicates only with the electronic wake-up tag, and the electromagnetic field of the secondary reader does not overlap with the electromagnetic field of the primary reader.

[0019] As a further aspect of the present invention: after the electronic document tag is awakened, it will re-enter a dormant state, with the time interval being a preset processing cycle.

[0020] The beneficial effects of this invention are as follows: The main function of this invention is to record and identify the borrowing and storage of physical files, providing convenience for employees to borrow or return physical files. It does not involve any specific mandatory control; the borrowing, retrieval, return, and placement of physical files are all performed by the employees themselves. Therefore, the application scenario of this invention is normal employee borrowing and returning. Unauthorized forced use by employees or unauthorized use by external personnel is not within the scope of this invention. The electronic wake-up tag of this invention is directly bound to the employee. Specifically, the binding method can be to place the electronic wake-up tag on the employee's work badge or other methods that are convenient to carry and not easily lost. When an employee goes to the file management module with the electronic wake-up tag, the electronic file tag corresponding to the physical file the employee wants can be retrieved through a database search. The employee's ID is entered and stored in their electronic wake-up tag via a secondary reader. When an employee enters the designated area, the primary reader identifies the information in the electronic wake-up tag and communicates with the specified electronic file tag to obtain the location coordinates of the target physical file and update the file status. Therefore, after a routine search, employees can find the location of the desired physical file upon reaching the filing cabinet and then retrieve it. Similarly, during the return process, an identification code is added to the electronic wake-up tag to distinguish it from the borrowed file. Upon reaching the filing cabinet, the employee can directly determine the location where the physical file should be returned, greatly simplifying the process of borrowing physical files and improving work efficiency. Attached Figure Description

[0021] The invention will now be further described with reference to the accompanying drawings.

[0022] Figure 1 is a schematic diagram of the structure of an RFID-based file storage management system according to the present invention. Detailed Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please refer to Figure 1. This invention is an RFID-based document storage management system, including a filing cabinet with several storage spaces inside for placing physical documents. It also includes:

[0025] The tag configuration module includes several electronic document tags and electronic wake-up tags. The electronic document tags are set in each storage space and bound to the storage space; the electronic wake-up tags are bound to employees.

[0026] The information acquisition module obtains the location coordinates of the storage space and the feature information of the physical archives. The feature information includes the name, author, and high-frequency words in the physical archives.

[0027] A primary reader / writer is used to emit radio frequency energy to form an electromagnetic field. The effective area of ​​the electromagnetic field is a spherical region centered on the filing cabinet, and the radius of the spherical region is a preset fixed value. The position coordinates, file status information, and feature information are entered into the corresponding electronic file tag. The file status information includes borrowing and storing.

[0028] The document management module includes a secondary reader / writer and a database. The database stores the characteristic information of physical documents and the IDs of their corresponding electronic document tags. It acquires borrowing requests and, through database retrieval, obtains the ID of the electronic document tag corresponding to the physical document to be borrowed. The secondary reader / writer then inputs the electronic document tag ID into an electronic wake-up tag. The borrowing request includes keywords, file name, and author. When the electronic wake-up tag enters the valid area, the reader / writer reads the electronic document tag ID from the electronic wake-up tag, wakes up the specified electronic document tag, and changes the file status in the electronic document tag to "borrowed."

[0029] The aforementioned file management module also includes:

[0030] Upon receiving a storage request, the identification code is entered into the electronic wake-up tag via a secondary reader / writer. After reading the identification code in the electronic wake-up tag, the primary reader / writer wakes up the corresponding electronic file tag and changes the file status in the electronic file tag to "storage". At the same time, the primary reader / writer deletes the information in the electronic wake-up tag.

[0031] First and foremost, it's important to note that the primary function of this invention is to record and identify the borrowing and storage of physical files, facilitating employee access to and return of these files. It does not involve any mandatory control measures; the borrowing, retrieval, and return of physical files are all performed by the employees themselves. Therefore, the application scenario of this invention is normal employee borrowing and returning. Unauthorized forced use by employees or unauthorized use by external personnel is not within the scope of this invention. The electronic wake-up tag of this invention is directly linked to the employee. Specifically, the tag can be attached to the employee's work badge or used in other convenient and secure ways. When an employee goes to the file management module with the electronic wake-up tag, the database can retrieve the electronic file tag corresponding to the physical file the employee wants. The employee's ID is entered and stored in their electronic wake-up tag via a secondary reader. When an employee enters the designated area, the primary reader identifies the information in the electronic wake-up tag and communicates with the specified electronic file tag to obtain the location coordinates of the target physical file and update the file status. Therefore, after a routine search, employees can find the location of the desired physical file upon reaching the filing cabinet and then retrieve it. Similarly, during the return process, an identification code is added to the electronic wake-up tag to distinguish it from the borrowed file. Upon reaching the filing cabinet, the employee can directly determine the location where the physical file should be returned, greatly simplifying the process of borrowing physical files and improving work efficiency.

[0032] In this embodiment, it is worth noting that, in a theoretical state, each electronic wake-up tag can only contain one electronic document tag ID. That is to say, an employee can only borrow one physical file at a time. If they want to borrow other physical files, they must borrow them before returning them.

[0033] In another preferred embodiment of the invention, to achieve efficient resource utilization, the electronic document tag remains in a dormant state when it does not receive a communication request from the reader / writer. While in dormant mode, only the data-storing portion of the electronic document tag is active. When the electronic document tag is woken up, it re-enters a dormant state, with the time interval being a preset processing cycle. This mode allows unused electronic document tags to remain dormant, saving power. Used electronic document tags also enter a dormant state after a period of time. It is worth noting that the electronic wake-up tag is carried by the employee, so an external switch can be set to allow the employee to wake it up or put it into dormant mode independently.

[0034] In a preferred embodiment of the present invention, considering the case where multiple people borrow the same physical file, during the borrowing process, if the file status in the electronic file tag is "borrowed" after the reader wakes up the designated electronic file tag, the borrowing is determined to have failed.

[0035] In this embodiment, it is worth noting that during the document borrowing process, after the primary reader changes the document status in the electronic document tag to "borrowed," it reads the location coordinates in the electronic tag and displays them to the employee through a display device, such as a common monitor or teleprompter.

[0036] Furthermore, to ensure that the two readers do not interfere with each other during the reading and writing process, the secondary reader only communicates with the electronic wake-up tag, and the electromagnetic field of the secondary reader does not overlap with that of the primary reader. Therefore, it can be understood that the primary and secondary readers are spatially separated by a distance greater than or equal to the sum of the radii of their electromagnetic fields. In practical applications, the secondary reader can be placed on the path leading to the filing cabinet, or in areas where employees congregate, such as break rooms or offices.

[0037] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
